Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
In the EPC network of LTE, adopt interface S11 between MME network element and SGW network element, adopt interface S58 between SGW network element and PGW network element, wherein, interface S11 and interface S58 adopts GTP-C agreement.
GTP-C agreement is by GTP-C to identifying two internodal chain of command transmission tunnels, and wherein, described GTP-C is formed the TEIDC being TEIDC and the local terminal distribution distributed by opposite end.Adopt GTP-C agreement to be beneficial to the management in path, but now need to ensure that the TEIDC distributed is unique at intra-office, then can unique identification transmission tunnel by TEIDC.
For interface S11, because the signaling of a user in communication process will be transmitted by a transmission tunnel, the contextual information of TEIDC and the UE therefore distributed will have relation one to one.Same in interface S58, the contextual information of TEIDC and the PDN of distribution will have relation one to one.
In order to ensure that the TEIDC distributed is unique at intra-office, and ensure the one-to-one relationship of TEIDC and the contextual information distributed, therefore the distribution method of a kind of TEIDC is, dispose the resource controlled block of the overall situation, and in this resource controlled block, be configured with a distribution node, adopt all TEIDCs of this distribution node to intra-office to carry out unified distribution and record.
When performing the distribution of TEIDC, distribution node can receive the distribution request that network element sends, the contextual information of user is comprised in described distribution request, distribution node is after determining the unallocated TEIDC of this user, can be this user distribution T EIDC, therefore first according to recording the TEIDC determining not to be assigned with, the user due to intra-office in this process be a lot, therefore by the method for searching, mating to come distribution T EIDC very loaded down with trivial details, efficiency is lower.After determining the TEIDC of distribution, the context of this user and the incidence relation of described TEIDC can be set up.Thus the transmission tunnel of this user can be determined, this user follow-up can in this transmission tunnel command transmitting.
But, adopt said method in the process of distribution T EIDC, determine that the process that TEIDC is not assigned with is more loaded down with trivial details according to record, all want query note to compare waste resource before every sub-distribution, affect allocative efficiency.
Embodiments provide the management method of a kind of TEIDC, adopt node instance to preserve the value of TEIDC and the index of corresponding contextual information, it is hereby ensured the uniqueness of TEIDC, and the one-to-one relationship of TEIDC and contextual information.Therefore, when distributing TEIDC, can obtain node instance successively from example array, thus obtain the value of TEIDC fast, allocative efficiency is higher.
With reference to Fig. 1, give the management method process flow diagram of a kind of TEIDC described in the embodiment of the present invention.
Step 101, obtains contextual information.
In actual treatment, MME network element and SGW network element, and adopt GTPC signaling message between SGW network element and PGW network element, when SGW network element judges that the message that MME sends is the first bag message of this user, obtain the TEIDC about this user that MME distributes within the message, and the contextual information of correspondence.
After this, SGW network element distributes a TEIDC will to this user, then feeds back to MME network element by response message, thus sets up a transmission tunnel (i.e. GTPC tunnel).
Concrete, described contextual information comprises: the contextual information of UE or the contextual information of PDN.As comprised the contextual information of UE in the message that received by interface S11, and for example, in the message received by interface S58, comprise the contextual information of PDN.
For interface S11, when base station detect the UE of user need to transmit tunnel carry out the transmission of data, signaling transmission time, base station can send request to MME network element, if MME network element sends GTPC signaling message to SGW network element, SGW network element obtains the contextual information of TEIDC and UE of this user from GTPC signaling message.
Whether step 102, detect described contextual information and meet pre-conditioned.
Described pre-conditioned be detect described contextual information whether meet pre-conditioned, if meet, then perform step 104, if do not meet, then perform step 103.
Because TEIDC and contextual information possess one-to-one relationship, if therefore user is registered in a network, namely there is the transmission tunnel of described user, then described user distributed TEIDC, just can be found the TEIDC of this user distribution by described contextual information, not need distribution T EIDC again.If user is not registered in a network, namely there is not the transmission tunnel of described user, then this user does not have TEIDC, needs for its distribution T EIDC.Therefore described pre-conditioned being configured to described contextual information can be there is not.
Then can detect in SGW network element the contextual information whether do not existed in described peer distribution request, if so, namely there is not described contextual information, then described contextual information meets pre-conditioned, follow-up execution step 104.If not, namely there is described contextual information, then described contextual information does not meet pre-conditioned, follow-up execution step 103.
Step 103, obtains the node instance that described contextual information is corresponding.
If described contextual information does not meet pre-conditioned, namely there is described contextual information, then can be found the value of the TEIDC corresponding with it by described contextual information.
In the embodiment of the present invention, node instance can be adopted to preserve the value of TEIDC and the index of contextual information, namely described node instance comprises the index of contextual information and the value of TEIDC, thus can be identified the corresponding relation of TEIDC and contextual information by described node instance.Owing to storing the value of TEIDC in node instance, and the index of the contextual information corresponding with it, therefore after getting contextual information, also can find corresponding node instance, be searched the value of TEIDC by described node instance.
Step 104, obtains a node instance from example array.
The embodiment of the present invention, will preserve the set array as an example of node instance, then example array can be preserved and be stored unappropriated node instance.
Therefore, when described contextual information meets pre-conditioned, when namely there is not described contextual information in SGW network element, a node instance can be obtained from described example array, to carry out the distribution of TEIDC.Specifically comprise the following steps:
With reference to Fig. 2, give the first node instance acquisition methods process flow diagram described in the embodiment of the present invention.
Step 201, obtains the chained list corresponding with described example array.
In the embodiment of the present invention, be also configured with chained list in SGW network element, described chained list is used for controlling example array, managing, and the headers and footers of concrete chained list points to a node instance in example array respectively.In the embodiment of the present invention, can there is Multi-instance array, therefore corresponding chained list also has multiple.
Wherein, when distributing node instance, the table tail of described chained list can be adopted to point to last node instance of described example array, gauge outfit points to any node example in example array.
Therefore, when for described user's distribution node example, the chained list corresponding with described example array first to be obtained, thus by described chained list distribution node example.
Step 202, obtains the node instance that described gauge outfit is pointed to.
The node instance that the gauge outfit that then can obtain described chained list is pointed to, feeds back to SGW network element by described node instance, thus realizes the distribution to node instance.
Step 203, keeps described table tail motionless, described gauge outfit is pointed to a rear node instance of the node instance obtained.
Then the table tail of described chained list can be kept motionless, described gauge outfit is performed a rear node instance of the node instance obtained.
With reference to Fig. 3, give the second node instance acquisition methods process flow diagram described in the embodiment of the present invention.
With reference to Fig. 4, give node instance described in the embodiment of the present invention and obtain schematic diagram.
In the embodiment of the present invention, can using the subscript of the value of TEIDC in node instance as this node instance.Thus the value of TEIDC just can be obtained fast when obtaining node instance.
Therefore, in order to manage the subscript of node instance and the value of TEIDC, the subscript of node instance each in example array can also be formed a set, using described set as subscript array, thus be assigned with a subscript array for instance number group, described subscript array can be adopted to manage the subscript of each node instance in described instance number group.
Wherein, in subscript array, described subscript is stored successively according to the order of memory node example in example array.Namely obtain the order of memory node example in example array, then in following table array, store subscript corresponding to each node instance successively according to described order.
As Fig. 4, storing node instance in example array L, is A, B, C and D respectively.Store the subscript of above-mentioned each node instance in corresponding subscript array L ＇ respectively, comprising: 0,1,2 and 3.
Also be configured with a chained list for controlling described subscript array L ＇, the headers and footers that can configure described chained list time initial points to first subscript 0 in subscript array L ＇ and last subscript 3 respectively.Then can be obtained the subscript in subscript array L ＇ by described chained list, and then determine node instance, complete the distribution of TEIDC.
Therefore, described from example array obtain a node instance, comprising:
Step 301, obtains the chained list corresponding with described subscript array.
Adopt the subscript of each node instance in subscript array admin instance array, therefore, the chained list corresponding with described following table array can also be configured, adopt the headers and footers of described chained list to point to a subscript in described following table array respectively.
In the embodiment of the present invention, the table tail of described chained list can be pointed to last subscript of described subscript array, gauge outfit points to arbitrary subscript in subscript array.As Fig. 4, under chained list is in original state, gauge outfit points to the subscript of subscript 0(solid line indication), table tail points to subscript 3.
Thus when distribution node example, first obtain the chained list corresponding with described following table array.
Step 302, obtains the subscript that described gauge outfit is pointed to, and determines corresponding node instance according to the subscript obtained.
The subscript that the gauge outfit that then can obtain described chained list is pointed to, as obtained 0 in Fig. 4, now just can get the value of TEIDC, but TEIDC will possess corresponding relation with contextual information, therefore, also according to described subscript, the node instance that this subscript is corresponding in example array to be searched, i.e. the node instance A of 0 correspondence.
Step 303, keeps the table tail of described chained list motionless, described gauge outfit is pointed to a subscript after the lower target of described acquisition.
As Fig. 4, maintenance table tail points to 3 motionless, by gauge outfit by the subscript of next subscript 1(dotted line indication pointing to 0).Thus complete the obtaining step of node instance.
Now, obtaining lower target time complexity is O(1).
In the embodiment of the present invention, adopt chained list to obtain node instance, simple to operate, efficiency is higher.And using the subscript of the value of TEIDC in node instance as this node instance, then the subscript of each node instance in subscript array admin instance array can be adopted, thus the value of TEIDC can be determined fast.
Step 105, associates the index of contextual information in described node instance with the contextual information in described peer distribution request, to distribute described node instance;
After determining the node instance of distributing, the index of described contextual information can be obtained from described node instance, the contextual information that then can will carry in peer distribution request, associate with the index of the contextual information in described node instance, thus establish the corresponding relation of TEIDC and contextual information, complete the distribution of node instance.
Wherein, described association refers to the index incidence relation setting up described contextual information and described contextual information, can be to associate etc. by setting up mapping relations.
Step 105 specifically comprises the following steps:
Based on the index of contextual information in described node instance, search the memory address of described contextual information; Contextual information in described peer distribution request is saved in described memory address.
Save the index of contextual information in node instance, also namely save the related data of searching contextual information, then can be found the memory address of corresponding contextual information by the index of described contextual information.
After determining the memory address of contextual information, contextual information in peer distribution request can be saved in described memory address, thus in node instance, have the value of TEIDC, and preserve the index of contextual information, corresponding contextual information can be found.Thus on the basis ensureing TEIDC uniqueness, also assures that the unique corresponding relation of TEIDC and contextual information.
Step 106, obtains the value of TEIDC, and returns from described node instance.
After determining the node instance of distributing, just can get the value of TEIDC from described node instance, and return to request transmit leg, MME network element or PGW network element.Thus make MME network element or PGW network element can obtain the TEIDC of distribution, combine the corresponding contextual information of UE or the contextual information of PDN simultaneously, build corresponding transmission tunnel, carry out the transmission of message, signaling.
In the embodiment of the present invention, the value of TEIDC comprises high-order portion and low portion, in order to more guarantee the uniqueness of TEIDC, and the wasting of resources reduced in node instance acquisition process, can using low portion in the value of TEIDC as the subscript of node instance interior joint example, then now only can get low portion in the value of TEIDC by the distribution of node instance, then also comprise following methods:
A selected signal command board, and obtain the sequence number of described signal command board, using the high-order portion of described sequence number as the value of described chain of command tunnel nodes mark TEIDC.
In actual treatment, the many employings of LTE system be the networking of many signal command boards, therefore node instance is being distributed, can according to the load sharing situation in data transmission procedure, select one piece of signal command board to distribute to corresponding UE or PDN, each signaling be in the transmission tunnel of this UE or PDN distribution can be sent to this signal command board.
Now, can get low portion in the value of TEIDC from the node instance of distributing, the sequence number due to described signal command board is all unique, therefore using described sequence number as high-order portion in the value of TEIDC, thus can guarantee the uniqueness of TEIDC.And the signal command board of signaling in the transmission tunnel that this TEIDC determines can also be determined to receive by the value of TEIDC.
With reference to Fig. 5, give the method for releasing process flow diagram of node instance described in the embodiment of the present invention.
In the embodiment of the present invention, when UE or PDN does not need transmission tunnel, if UE is mobile phone, detect that this has shut down, now no longer need the transmission tunnel of this UE or PDN, when namely having corresponding relation in TEIDC and UE contextual information, can also node instance be discharged.
The then method for releasing of node instance, specifically comprises:
Step 501, obtains the chained list corresponding with described subscript array;
When carrying out the release of node instance, the table tail of chained list can be adopted time initial to point to first subscript of following table array, and gauge outfit points to arbitrary subscript in following table array.Then in dispose procedure, the table tail of described chained list and gauge outfit point to a subscript in described subscript array respectively, then can obtain described chained list.
Step 502, discharges the subscript that described table tail points to, and the node instance that described subscript is corresponding;
The subscript that the table tail that then can discharge described chained list points to, and determine the node instance that described subscript is pointed to, discharge described node instance.
Step 503, keeps described gauge outfit motionless, by a subscript after the lower target of described table tail sensing release.
Then keep described gauge outfit motionless, by a subscript after the lower target of described table tail sensing release.Corresponding subscript can be discharged fast when making perform releasing operation next time.
In sum, the embodiment of the present invention adopts node instance to store the index of contextual information and the value of TEIDC, thus has both ensured the value uniqueness of TEIDC, in turn ensure that the corresponding relation of TEIDC and contextual information.Therefore according to peer distribution acquisition request contextual information, thus after determining to need distribution T EIDC, can obtain a node instance from example array, now can determine the value of TEIDC, TEIDC distribution method is very convenient, simple.Again by the contextual information in peer distribution request, associate with the index of the contextual information in node instance, thus establish the corresponding relation of TEIDC and contextual information, the foundation of corresponding relation is very convenient, simple to operate.Complete the distribution of node instance, also namely complete the distribution of TEIDC, the value of TEIDC can be returned.Thus the embodiment of the present invention can distribution T EIDC efficiently, and the corresponding relation of TEIDC and contextual information efficiently, easy and simple to handle, save time, efficiency is higher.
Secondly, the present invention using the subscript of the value of TEIDC in node instance as this node instance, can also adopt subscript array to manage the subscript of each node instance in described instance number group, thus has unified management to the value of TEIDC.Then timestamp under employing chained list obtains, just can obtain the value of TEIDC fast.
Again, in the embodiment of the present invention, the value of TEIDC comprises high-order portion and low portion, in order to reduce the waste of resource, and can using low portion in the value of TEIDC as the subscript of node instance interior joint example.Then after distributing node instance, can using the high-order portion of the sequence number of selected signal command board as the value of TEIDC, wherein, the signaling of the transmission tunnel transmission that this TEIDC identifies all will be received by described selected signal command board.Thus on the basis determining TEIDC uniqueness, decrease the waste of resource.
