Description
INTERNETWORKING AIR-TO-AIR NETWORK AND WIRELESS
NETWORK
Backizround [0001] Existing aeronautical data link services based on VHF ground stations, which are installed across landmasses to provide line-of-sight air-to-ground data link communications, are relatively expensive for airspace users. This is in part due to capital equipment required to install the ground stations as well as on going maintenance costs. In particular, current domestic aeronautical data links (ACARS) use an expensive, in terms of both capital and maintenance, ground station network where the ground stations are spaced approximately every 150 miles, where 150 miles is the approximate radio range of VHF
communications from an aircraft. This results in hundreds of ground stations, used only for aeronautical data link, in high density domestic airspaces in the US, Europe and other areas around the world.
These ACARS networks work in a star configuration where ground stations are connected to a central processor which serves as the master router. The central processor knows the ground station used for a downlink from an aircraft and uses that same ground station for an uplink to the aircraft. If the aircraft does not respond to an uplink, the central processor sends the message out via adjacent ground stations until it finds the aircraft.

[0002] Air-to-air networking provides one possible solution which does not rely on capital intensive ground stations. In an air-to-air network, aircraft form mobile nodes capable of relaying messages from one aircraft to another aircraft or to a ground station at the intended destination which is beyond the communication range of the originating aircraft.
Air-to-air networks, where the message is relayed entirely via the air-to-air network from the source to the destination, however, have a disadvantage when a message needs to be relayed over a long distance because they consume more radio frequency spectrum than direct air-to-ground communications.

Detailed Description [0014] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the inventions may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, mechanical and electrical changes may be made without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defmed only by the claims and equivalents thereof.
[0015] Embodiments of the present invention utilize hybrid air-to-air and wireless networks to provide aeronautical communications. In particular, in embodiments, air-to-air networks are used until an aircraft comes within the range of a wireless network. This is possible, with the emergence of wireless networks with metropolitan coverage of approximately several kilometers up to 100 kilometers and beyond. The use of wireless networks provides a cost effective solution for aeronautical communications.
Embodiments take advantage of commercially available wireless networks, such as but not limited to, WiMAX and Wireless Regional Area Networks (WRANs) which are emerging in the marketplace. Since WiMAX and WRAN can handle significantly more data traffic than ACARS and will have many more paying customers, the cost per kilobyte should be much less. The drawback is the shorter range. As discussed above, Wireless WiMAX
will likely have ranges up to several km and WRANs perhaps up to 100 km. To communicate with aircraft further away from the WiMAX or WRAN access point or base station, this invention makes use of air-to-air networking, where the aircraft act as ad-hoc nodes.
One element of the communication system of embodiments is a Ground Station Controller which is a router that maintains the routing topology of aircraft (mobile nodes) that are within communications range of a wireless access point (transceiver).
H0018085-543co [0016] Referring to Figure 1, an example of a communication network 100 of one embodiment is illustrated. As illustrated, this network 100 includes ground station controllers (GSC) 106 (1-N) and a terrestrial end system 104. Each GSC 106 can be generally referred to as a route computing system. As discussed above, each GSC 106 is a router that maintains the topology of aircraft that are within communication range of wireless access points in a memory 105. The network 100 also includes aircraft 102-1 through 102-11, ground stations 108-1 through 108-3 and an end system 104. In Figure 1, some aircraft 102 include an indication of a radio range 110-1 through 110-6. For example, aircraft 102-2 has a radio range 110-1. The ground stations 108 also include an indication of a radio range 112-1 through 112-3. For example, ground station 108-1 has a radio range of 112-1.
The ground stations 108 are in communication with the GSC 106 via communication links 114-1 through 114-3 which are part of a network such as but not limited to the internet. The network can be generally referred to as a terrestrial network. In embodiments, the aircraft 102 form ad-hoc communication networks to pass messages between communication peers in a communication network 100. The communication peers are made up of the aircrafts 102 and the end system 104. Although, embodiments of the present invention are described above and below as applying to air-to-air communication networks, other embodiments apply to any type of mobile-to-mobile communication network and the present invention is not limited to air-to-air communication networks.
[0017] As discussed above, embodiments establish conununication paths through the communication network 100. That is, embodiments establish communication paths both to and from any airborne (mobile) node and a terrestrial node (one fixed, wired or wireless on a network such as an internet network) via an air-to-air network and a WiMAX, WRAN or similar wireless communication network (herein generally referred to as a Wireless Network (WN)). Referring to Figure 2, a register and unregister flow diagram 200 is illustrated. It illustrates one method of registering and unregistering a gateway with a GSC
as well as the topology information transfer. As illustrated, the process begins when an aircraft (node) establishes a connection with a WN (202). Once, a connection is established between the node (which will be the gateway) and the WN through a respective ground station 108, the node sends the topology information it has to the GSC over a terrestrial network such as but not limited to an internet protocol (IP) Network (204). The topology information relates to H00 t 8085-5435 the connectivity status, location and identification of nodes (aircraft) that make up the air-to-air network with which the gateway node is associated. An example of a system that discovers the topology of the air-to-air network is provided in the commonly assigned patent application having an Application Number 12/025,685, entitled "Use of Alternate Communication Networks to Complement an Ad-Hoc mobile node to Mobile Node Communication Network", which is herein incorporated in its entirety. If the gateway node is not already registered with the GSC, it registers itself as a gateway to its associated air-to-air network with the GSC (204). The GSC dynamically updates topology information in the memory 105 associated with each registered gateway based on the received topology information (206). In embodiments, the gateway also initially advertises to its associated air-to-air network that it is available as a gateway to the ground (203). In embodiments, the gateway further periodically advertises to its associated air-to-air network that it is still available as a gateway to the ground. Further in embodiments, each gateway periodically sends its then current topology to the GSC (204). Examples of gateway nodes (or gateway aircraft) are aircraft 102-5, 102-6 and 102-11 of Figure 1.
[0018] As also illustrated, in flow diagram 200 of Figure 2, in embodiments, when a gateway node determines it is leaving the radio range of the WN (208), the gateway node sends an unregister message though the respective ground station to the GSC
(210). The GSC then dynamically updates its topology information based on the received information (206). Different events can be used to trigger an unregister message. Examples of events include but are not limited to, an aircraft departing an airport which has a WN access point, the aircraft traveling a predetermined distance since it established connectivity with the WN
access point as well as events determined by algorithms that indicate the gateway node is moving outside of the range of a peer receiver. By unregistering the gateway aircraft, the GSC is prevented from using the aircraft as an entry point to the air-to-air communication network after the aircraft has left the WN coverage. As Figure 2 also illustrates, the node also advertises to its associated air-to-air network that it is no longer available as a gateway to the ground when it determines it is leaving the radio range of the WN (212).
[0019] Figure 3A illustrates an uplink message flow diagram 300 of one embodiment of the present invention. In particular, it illustrates an example of one method of delivering a message to an aircraft through the communication network 100. In this example, an end H00 : 5085-5435 system 104 wants to deliver a message to an aircraft. The end system 104 sends the uplink message to a GSC 106 (302). The GSC selects a specific aircraft gateway based on the then current topology information it has on the air-to-air networks in the communication network 100 (304). The GSC encapsulates the uplink information in a message having a protocol specific format used by the wireless network and addresses the message to the selected gateway (306). An example of a message protocol is an IP message having an IP
address of the selected gateway. Although, the following description describes embodiments using IP
messages and IP addresses, the present invention is not limited to IP
messages. As stated above, any type of terrestrial network having its own protocol can be used.
The GSC then transmits the protocol specific message to the selected gateway via the associated ground station 108 through the internet (308). Since a protocol specific message is used, basic routing used by the terrestrial network directs the delivery of the protocol specific message through the ground station (108) to the gateway aircraft (102). Once, the gateway receives the protocol specific message it extracts the uplink message (310). In embodiments, the encapsulated message contains addressing information used to determine routing of the message to the destination aircraft through the air-to-to air network. The addressing information may include but is not limited to, aircraft tail number, an International Civil Aviation Organization (ICAO) aircraft ID address or another type of address identification scheme. The gateway then uses the air-to-air network to deliver the uplink message to the destination aircraft (312) based on the then current topology of the air-to-air communication network.
[0020] Referring to Figure 1, an example of the delivery of an uplink message is provided. In this example, end system 104 needs to deliver an uplink message to aircraft (node) 102-1. In this example, the end system 104 sends the uplink message to a GSC 106 which in this example is GSC 106-1. Once the GSC 106 receives the message, it determines where the destination aircraft is based on its then current topology information received via the gateway aircraft 102-5. In this example, GSC 106 will recognize based on the then current topology information that the destination aircraft 102-1 can be reached via gateway aircraft 102-5 through a WN of ground station 108-1 and the air-to air network made up of gateway aircraft 102-5, aircraft 102-4, aircraft 102-3, aircraft 102-2 and the destination aircraft 102-1. Communication link 114-1 (like connections 114-2 and 114-3) are available internet or private network connections. In one embodiment using an internet connection, an IP address of the gateway aircraft 102-5 is used to deliver the uplink message over communication link 114-1. Accordingly, based on this information, internet routers send the uplink message to ground station 108-1 via communication link 114-1. Ground station 108-1 then transmits the uplink message via the wireless network (WN) to gateway aircraft 102-5 that is within the radio range 112-1 of the WN. The uplink message is then passed to destination aircraft 102-1, via the path through the air-to air network made up of gateway aircraft 102-5, aircraft 102-4, aircraft 102-3, aircraft 102-2 and the destination aircraft 102-1.
[0021] Figure 3B illustrates another upload message flow diagram (320) of another embodiment of the present invention. In this embodiment, the process starts when the end system 104 determines it needs to send a message to an aircraft 102. The end system 104 sends a message to the GSC 106 indicating the destination aircraft (322).
Based on the then current topology information that it has, the GSC 106 determines which gateway 102-5, 102-6 or 102-11, provides an optimal communication link to the select aircraft (324). In one embodiment, a domain name server (DNS) like server is used to translate a host name of the gateway to a protocol specific address such as an IP address. The GSC 106 then provides the protocol specific address of the gateway 102-5, 102-6 or 102-11 to the end system 104 (326).
The end system 104 then uses the IP address to communicate with the aircraft 102 via the select gateway 102-5, 102-6 or 102-11. For example, referring to Figure 1, end system 104 wants to send a message to aircraft 102-10. In this embodiment, end system 104 tells GSC
106-1 (which can be referred to as a route computing system 106-1) that it wants to send a message to aircraft 102-10. GSC 106-1 checks its then current topology and determines that an optimal path to aircraft 102-10 is through gateway 102-11. GSC 106-1 then sends the protocol specific address of gateway 102-11 to the end system 104. End system 104 then sends its message to aircraft 102-10 using the protocol specific address for gateway 102-11.
Gateway 102-11 then extracts the message and transmits it to the destination aircraft 102-10.
[0022] Figure 4, illustrates a downlink message flow diagram 400 of one embodiment. In this example, a message is to be sent from an aircraft to the select end system. First the originating aircraft determines a gateway aircraft to use to deliver the downlink message. In one embodiment, an optimal path algorithm is applied to the topology of the air-to-air network associated with the aircraft to select the gateway aircraft (402). The downlink message is then passed through the air-to-air network to the gateway aircraft (404). The gateway aircraft then communicates the message over the WN where it is delivered to the terrestrial destination (406). In one embodiment, the gateway aircraft is configured with the terrestrial destination address and basic internet routing. In another embodiment, the source aircraft addresses the message to the end-system directly without the need to configure each gateway aircraft. If the downlink is addressed for multiple end destinations (multicast), at least one of the gateway aircraft and source aircraft has routing capabilities with multiple end-system addresses configured. As discussed above, the gateway aircraft, in response to a triggering event, will advertise to its associated air-to-air ad-hoc network that it is unavailable as a gateway to the ground. In one embodiment, a timeout is used for the gateway usage since the gateway aircraft is expected to periodically advertise its availability as a gateway to the air-to-air network as discussed above.
[0023] Referring to Figure 1, an example of a downlink message is discussed.
In this example, aircraft 102-8 needs to send a downlink message to end system 104.
Once aircraft 102-8 determines that it needs to send the downlink message, it determines the best route to send the message to end system 104. In particular, aircraft 102-8 will apply an optimal path algorithm to select a path. In this case, aircraft 102-8 can use either gateway aircraft 102-6 or 102-11. Since, the path to gateway aircraft 102-6 is optimal, that is the path that will be chosen by the routing algorithm. This path consists of aircraft 102-7 and the gateway aircraft 102-6. As illustrated, the gateway aircraft 102-6 is within the radio range 112-2 of WN point of ground station 108-2. As described above, the gateway aircraft 102-6 encapsulates the downiink message in a protocol specific message directed to the destination end system 104.
The gateway aircraft then transmits the protocol specific message to ground station 108-2 via the WN. Based on the message being addressed to destination end system 104, routers of the terrestrial network send the message to end system 104 through communication links 114-2.
[0024] It will be understood that, although the above examples discuss communicating messages between aircraft and terrestrial end systems, embodiments can exchange messages between aircraft using the communication network 100 as described above. For example, the GSC 106 and related WN can serve to offer a more spectrum efficient method to enable two mobile nodes 102 (one source and one destination) to communicate. In this embodiment, the message would originate in a mobile node, follow the optimal routing over the mobile-to-x0011 8085-5435 mobile network to a WN gateway 102-5, 102-6 or 102-11, then be transmitted over a terrestrial network to a WN gateway 102-5, 102-6 or 102-11 with optimal air-to-air routing to the destination mobile node 102.
[0025] Figure 5 illustrates a vehicle communication system 500 block diagram of one embodiment of the present invention. The vehicle communication system 500 includes a communication management function (CMF) 510 that controls the communications of the communication system. In this embodiment, the vehicle communication system 500 includes two communication transceivers, an air-to-air network transceiver (HF, VHF, or other system) 514 and a wireless network (WN) transceiver (520). The air-to-air network transceiver 514 sends and receives signals via antenna 518 and WN transceiver 520 sends and receives signals via antenna 522. The air-to-air network transceiver 514 is used to send and receive air-to-air signals with other aircraft to form the ad-hoc air-to-air network. The WN
transceiver 520 is used to send and receive wireless signals over a communication network such as WiIvIAX, WRAN or similar wireless communication scheme to allow access to the terrestrial network such as but not limited to the Internet or other private IP network. In embodiments, when the WN transceiver 520 is in communication with a WN, the enters into the gateway mode and directs the WN transceiver 520 to send register signals and unregister signals to a GSC as discussed above in regards to Figure 2. Also illustrated in Figure 5 are route and encapsulate algorithms 525 that are used by the CMF.
The route algorithms are used to determine the optimal route to a select destination in the communication network. The encapsulate algorithms are used to encapsulate and extract downlink and uplink messages in protocol specific messages as discussed above.
As further discussed above, in some embodiments the CMF addresses encapsulated downlink messages to the GSC. Figure 5, further includes a surveillance transceiver 512 and an associated antenna 516 which in one embodiment is used in part for discovery of air-to-to air network of aircraft as is discussed in the commonly owned Patent Application No.

The network 100 also includes aircraft 102-1 through 102-11, ground stations 108-1 through 108-3 and an end system 104. In Figure 1, some aircraft 102 include an indication of a radio range 110-1 through 110-6. For example, aircraft 102-2 has a radio range 110-1. The ground stations 108 also include an indication of a radio range 112-1 through 112-3. For example, ground station 108-1 has a radio range of 112-1.
The ground stations 108 are in communication with the GSC 106 via communication links 114-1 through 114-3 which are part of a network such as but not limited to the internet. The network can be generally referred to as a terrestrial network. In embodiments, the aircraft 102 form ad-hoc communication networks to pass messages between communication peers in a communication network 100.

[0017] As discussed above, embodiments establish conununication paths through the communication network 100. That is, embodiments establish communication paths both to and from any airborne (mobile) node and a terrestrial node (one fixed, wired or wireless on a network such as an internet network) via an air-to-air network and a WiMAX, WRAN or similar wireless communication network (herein generally referred to as a Wireless Network (WN)).

Once, a connection is established between the node (which will be the gateway) and the WN through a respective ground station 108, the node sends the topology information it has to the GSC over a terrestrial network such as but not limited to an internet protocol (IP) Network (204). The topology information relates to H00 t 8085-5435 the connectivity status, location and identification of nodes (aircraft) that make up the air-to-air network with which the gateway node is associated. An example of a system that discovers the topology of the air-to-air network is provided in the commonly assigned patent application having an Application Number 12/025,685, entitled "Use of Alternate Communication Networks to Complement an Ad-Hoc mobile node to Mobile Node Communication Network", which is herein incorporated in its entirety. If the gateway node is not already registered with the GSC, it registers itself as a gateway to its associated air-to-air network with the GSC (204). The GSC dynamically updates topology information in the memory 105 associated with each registered gateway based on the received topology information (206). In embodiments, the gateway also initially advertises to its associated air-to-air network that it is available as a gateway to the ground (203). In embodiments, the gateway further periodically advertises to its associated air-to-air network that it is still available as a gateway to the ground. Further in embodiments, each gateway periodically sends its then current topology to the GSC (204). Examples of gateway nodes (or gateway aircraft) are aircraft 102-5, 102-6 and 102-11 of Figure 1.
[0018] As also illustrated, in flow diagram 200 of Figure 2, in embodiments, when a gateway node determines it is leaving the radio range of the WN (208), the gateway node sends an unregister message though the respective ground station to the GSC
(210). The GSC then dynamically updates its topology information based on the received information (206). Different events can be used to trigger an unregister message. Examples of events include but are not limited to, an aircraft departing an airport which has a WN access point, the aircraft traveling a predetermined distance since it established connectivity with the WN
access point as well as events determined by algorithms that indicate the gateway node is moving outside of the range of a peer receiver. By unregistering the gateway aircraft, the GSC is prevented from using the aircraft as an entry point to the air-to-air communication network after the aircraft has left the WN coverage. As Figure 2 also illustrates, the node also advertises to its associated air-to-air network that it is no longer available as a gateway to the ground when it determines it is leaving the radio range of the WN (212).
[0019] Figure 3A illustrates an uplink message flow diagram 300 of one embodiment of the present invention. In particular, it illustrates an example of one method of delivering a message to an aircraft through the communication network 100. In this example, an end H00 : 5085-5435 system 104 wants to deliver a message to an aircraft. The end system 104 sends the uplink message to a GSC 106 (302). The GSC selects a specific aircraft gateway based on the then current topology information it has on the air-to-air networks in the communication network 100 (304). The GSC encapsulates the uplink information in a message having a protocol specific format used by the wireless network and addresses the message to the selected gateway (306). An example of a message protocol is an IP message having an IP
address of the selected gateway. Although, the following description describes embodiments using IP
messages and IP addresses, the present invention is not limited to IP
messages. As stated above, any type of terrestrial network having its own protocol can be used.
The GSC then transmits the protocol specific message to the selected gateway via the associated ground station 108 through the internet (308). Since a protocol specific message is used, basic routing used by the terrestrial network directs the delivery of the protocol specific message through the ground station (108) to the gateway aircraft (102). Once, the gateway receives the protocol specific message it extracts the uplink message (310). In embodiments, the encapsulated message contains addressing information used to determine routing of the message to the destination aircraft through the air-to-to air network. The addressing information may include but is not limited to, aircraft tail number, an International Civil Aviation Organization (ICAO) aircraft ID address or another type of address identification scheme. The gateway then uses the air-to-air network to deliver the uplink message to the destination aircraft (312) based on the then current topology of the air-to-air communication network.
[0020] Referring to Figure 1, an example of the delivery of an uplink message is provided. In this example, end system 104 needs to deliver an uplink message to aircraft (node) 102-1. In this example, the end system 104 sends the uplink message to a GSC 106 which in this example is GSC 106-1. Once the GSC 106 receives the message, it determines where the destination aircraft is based on its then current topology information received via the gateway aircraft 102-5. In this example, GSC 106 will recognize based on the then current topology information that the destination aircraft 102-1 can be reached via gateway aircraft 102-5 through a WN of ground station 108-1 and the air-to air network made up of gateway aircraft 102-5, aircraft 102-4, aircraft 102-3, aircraft 102-2 and the destination aircraft 102-1. Communication link 114-1 (like connections 114-2 and 114-3) are available internet or private network connections. In one embodiment using an internet connection, an IP address of the gateway aircraft 102-5 is used to deliver the uplink message over communication link 114-1. Accordingly, based on this information, internet routers send the uplink message to ground station 108-1 via communication link 114-1. Ground station 108-1 then transmits the uplink message via the wireless network (WN) to gateway aircraft 102-5 that is within the radio range 112-1 of the WN. The uplink message is then passed to destination aircraft 102-1, via the path through the air-to air network made up of gateway aircraft 102-5, aircraft 102-4, aircraft 102-3, aircraft 102-2 and the destination aircraft 102-1.
[0021] Figure 3B illustrates another upload message flow diagram (320) of another embodiment of the present invention. In this embodiment, the process starts when the end system 104 determines it needs to send a message to an aircraft 102. The end system 104 sends a message to the GSC 106 indicating the destination aircraft (322).
Based on the then current topology information that it has, the GSC 106 determines which gateway 102-5, 102-6 or 102-11, provides an optimal communication link to the select aircraft (324). In one embodiment, a domain name server (DNS) like server is used to translate a host name of the gateway to a protocol specific address such as an IP address. The GSC 106 then provides the protocol specific address of the gateway 102-5, 102-6 or 102-11 to the end system 104 (326).
The end system 104 then uses the IP address to communicate with the aircraft 102 via the select gateway 102-5, 102-6 or 102-11. For example, referring to Figure 1, end system 104 wants to send a message to aircraft 102-10. In this embodiment, end system 104 tells GSC
106-1 (which can be referred to as a route computing system 106-1) that it wants to send a message to aircraft 102-10. GSC 106-1 checks its then current topology and determines that an optimal path to aircraft 102-10 is through gateway 102-11. GSC 106-1 then sends the protocol specific address of gateway 102-11 to the end system 104. End system 104 then sends its message to aircraft 102-10 using the protocol specific address for gateway 102-11.
Gateway 102-11 then extracts the message and transmits it to the destination aircraft 102-10.
[0022] Figure 4, illustrates a downlink message flow diagram 400 of one embodiment. In this example, a message is to be sent from an aircraft to the select end system. First the originating aircraft determines a gateway aircraft to use to deliver the downlink message. In one embodiment, an optimal path algorithm is applied to the topology of the air-to-air network associated with the aircraft to select the gateway aircraft (402). The downlink message is then passed through the air-to-air network to the gateway aircraft (404). The gateway aircraft then communicates the message over the WN where it is delivered to the terrestrial destination (406). In one embodiment, the gateway aircraft is configured with the terrestrial destination address and basic internet routing. In another embodiment, the source aircraft addresses the message to the end-system directly without the need to configure each gateway aircraft. If the downlink is addressed for multiple end destinations (multicast), at least one of the gateway aircraft and source aircraft has routing capabilities with multiple end-system addresses configured. As discussed above, the gateway aircraft, in response to a triggering event, will advertise to its associated air-to-air ad-hoc network that it is unavailable as a gateway to the ground. In one embodiment, a timeout is used for the gateway usage since the gateway aircraft is expected to periodically advertise its availability as a gateway to the air-to-air network as discussed above.
[0023] Referring to Figure 1, an example of a downlink message is discussed.
In this example, aircraft 102-8 needs to send a downlink message to end system 104.
Once aircraft 102-8 determines that it needs to send the downlink message, it determines the best route to send the message to end system 104. In particular, aircraft 102-8 will apply an optimal path algorithm to select a path. In this case, aircraft 102-8 can use either gateway aircraft 102-6 or 102-11. Since, the path to gateway aircraft 102-6 is optimal, that is the path that will be chosen by the routing algorithm. This path consists of aircraft 102-7 and the gateway aircraft 102-6. As illustrated, the gateway aircraft 102-6 is within the radio range 112-2 of WN point of ground station 108-2. As described above, the gateway aircraft 102-6 encapsulates the downiink message in a protocol specific message directed to the destination end system 104.
The gateway aircraft then transmits the protocol specific message to ground station 108-2 via the WN. Based on the message being addressed to destination end system 104, routers of the terrestrial network send the message to end system 104 through communication links 114-2.
[0024] It will be understood that, although the above examples discuss communicating messages between aircraft and terrestrial end systems, embodiments can exchange messages between aircraft using the communication network 100 as described above. For example, the GSC 106 and related WN can serve to offer a more spectrum efficient method to enable two mobile nodes 102 (one source and one destination) to communicate. In this embodiment, the message would originate in a mobile node, follow the optimal routing over the mobile-to-x0011 8085-5435 mobile network to a WN gateway 102-5, 102-6 or 102-11, then be transmitted over a terrestrial network to a WN gateway 102-5, 102-6 or 102-11 with optimal air-to-air routing to the destination mobile node 102.
[0025] Figure 5 illustrates a vehicle communication system 500 block diagram of one embodiment of the present invention. The vehicle communication system 500 includes a communication management function (CMF) 510 that controls the communications of the communication system. In this embodiment, the vehicle communication system 500 includes two communication transceivers, an air-to-air network transceiver (HF, VHF, or other system) 514 and a wireless network (WN) transceiver (520). The air-to-air network transceiver 514 sends and receives signals via antenna 518 and WN transceiver 520 sends and receives signals via antenna 522. The air-to-air network transceiver 514 is used to send and receive air-to-air signals with other aircraft to form the ad-hoc air-to-air network. The WN
transceiver 520 is used to send and receive wireless signals over a communication network such as WiIvIAX, WRAN or similar wireless communication scheme to allow access to the terrestrial network such as but not limited to the Internet or other private IP network. In embodiments, when the WN transceiver 520 is in communication with a WN, the enters into the gateway mode and directs the WN transceiver 520 to send register signals and unregister signals to a GSC as discussed above in regards to Figure 2. Also illustrated in Figure 5 are route and encapsulate algorithms 525 that are used by the CMF.
The route algorithms are used to determine the optimal route to a select destination in the communication network. The encapsulate algorithms are used to encapsulate and extract downlink and uplink messages in protocol specific messages as discussed above.
As further discussed above, in some embodiments the CMF addresses encapsulated downlink messages to the GSC. Figure 5, further includes a surveillance transceiver 512 and an associated antenna 516 which in one embodiment is used in part for discovery of air-to-to air network of aircraft as is discussed in the commonly owned Patent Application No.
