To identifying two internodal chain of command transmission tunnels, wherein, described GTP-C is to being that the TEIDC that the TEIDC that distributed by the opposite end and local terminal distribute consists of by GTP-C for the GTP-C agreement.Adopt the GTP-C agreement to be beneficial to the management in path, but need this moment to guarantee that the TEIDC that distributes is unique at intra-office, by TEIDC can unique identification a transmission tunnel.
Take interface S11 as example, because the signaling of a user in communication process will be transmitted by a transmission tunnel, the TEIDC that therefore distributes and the contextual information of UE will have relation one to one.In interface S58, the TEIDC of distribution and the contextual information of PDN will have relation one to one equally.
For the TEIDC that guarantees to distribute is unique at intra-office, and guarantee the TEIDC of distribution and the one-to-one relationship of contextual information, therefore the distribution method of a kind of TEIDC is, dispose the resource control module of the overall situation, and configured a distribution node in this resource control module, adopt this distribution node to carry out unified distribution and record to all TEIDC of intra-office.
Carrying out minute timing of TEIDC, distribution node can receive the distribution request that network element sends, the contextual information that comprises the user in described distribution request, distribution node is after definite unallocated TEIDC of this user, can be this user assignment TEIDC, therefore at first according to the definite TEIDC that is not assigned with of record, the user due to intra-office in this process is a lot, therefore very loaded down with trivial details of the method by searching, mate to come distribution T EIDC, efficient is lower.After the TEIDC that has determined to distribute, can set up this user's context and the incidence relation of described TEIDC.Thereby can determine this user's transmission tunnel, follow-up this user can be transmitted command transmitting in the tunnel at this.
But, adopt said method in the process of distribution T EIDC, the process that is not assigned with according to the definite TEIDC of record is more loaded down with trivial details, all wants query note relatively to waste resource before every sub-distribution, affects allocative efficiency.
The embodiment of the present invention provides the management method of a kind of TEIDC, adopts 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 dividing timing to TEIDC, can obtain node instance successively from the example array, thereby obtain fast the value of TEIDC, allocative efficiency is higher.
With reference to Fig. 1, provided the management method process flow diagram of the described a kind of TEIDC of the embodiment of the present invention.
In actual treatment, MME network element and SGW network element, and employing GTPC signaling message between SGW network element and PGW network element, when the message of SGW network element judgement MME transmission is the first bag message of this user, obtain the TEIDC about this user that MME distributes in this message, and corresponding contextual information.
After this, the SGW network element will be given TEIDC of this user assignment, then feeds back to the MME network element by response message, thereby sets up a transmission tunnel (being the GTPC tunnel).

Whether step 102 detects described contextual information and meets pre-conditioned.
Described pre-conditioned be to detect described contextual information whether to meet pre-conditionedly, if meet, execution in step 104, if do not meet, execution in step 103.
Because TEIDC and contextual information possess one-to-one relationship, if therefore the user registered in network, namely there is described user's transmission tunnel, described user had distributed TEIDC, just can find the TEIDC of this user assignment by described contextual information, not need distribution T EIDC again.If the user did not register in network, namely there is not described user's transmission tunnel, this user does not have TEIDC, need to be its distribution T EIDC.Therefore can the described pre-conditioned described contextual information that is configured to not exist.
Can detect and whether not exist described node to distribute contextual information in request in the SGW network element, if, namely do not have described contextual information, described contextual information meet pre-conditioned, follow-up execution in step 104.If not, namely have described contextual information, described contextual information do not meet pre-conditioned, follow-up execution in step 103.
Step 103 is obtained node instance corresponding to described contextual information.
If it is pre-conditioned that described contextual information does not meet, namely there is described contextual information, can find the value of the TEIDC corresponding with it by described contextual information.
In the embodiment of the present invention, can adopt node instance to preserve the value of TEIDC and the index of contextual information, be the value that described node instance comprises index and the TEIDC of contextual information, thereby can identify the corresponding relation of TEIDC and contextual information by described node instance.Due to the value that stores 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, the value of searching TEIDC by described node instance.
Step 104 is obtained a node instance from the example array.
The embodiment of the present invention, with the set of preserving node instance array as an example, the example array can be preserved the unappropriated node instance of storage.
Therefore, when described contextual information meets when pre-conditioned, when namely not having described contextual information in the SGW network element, a node instance can be obtained, to carry out the distribution of TEIDC from described example array.Specifically comprise the following steps:
With reference to Fig. 2, provided the described the first node instance of embodiment of the present invention acquisition methods process flow diagram.
Step 201 is obtained the chained list corresponding with described example array.
In the embodiment of the present invention, also configured chained list in the SGW network element, described chained list is used for the example array is controlled, managed, and the headers and footers of concrete chained list points to respectively a node instance in the example array.In the embodiment of the present invention, can have the Multi-instance array, therefore corresponding chained list also has a plurality of.
Wherein, dividing timing to node instance, can adopt last node instance of the described example array of table tail sensing of described chained list, gauge outfit is pointed to arbitrary node instance in the example array.
Therefore, when being described user assignment node instance, at first to obtain the chained list corresponding with described example array, thereby by described chained list distribution node example.
Step 202 is obtained the node instance that described gauge outfit is pointed to.
Then can obtain the node instance of the gauge outfit sensing of described chained list, described node instance is fed back to the SGW network element, thereby realize 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 of obtaining.
Then can keep the table tail of described chained list motionless, described gauge outfit be carried out a rear node instance of the node instance of obtaining.
With reference to Fig. 3, provided the described the second node instance of embodiment of the present invention acquisition methods process flow diagram.
With reference to Fig. 4, provided the described node instance of the embodiment of the present invention and obtained schematic diagram.
In the embodiment of the present invention, can be with the value of TEIDC in the node instance subscript as this node instance.Thereby just can obtain fast the value of TEIDC when obtaining node instance.
Therefore, the value that is TEIDC for the subscript to node instance manages, the subscript of each node instance in the example array can also be consisted of a set, with described set as the subscript array, thereby joined a subscript array for the instance number component, can adopt the subscript of each node instance in the described instance number group of described subscript array management.
Wherein, store successively described subscript according to the order of memory node example in the example array in the subscript array.Namely obtain the order of memory node example in the example array, then store successively subscript corresponding to each node instance according to described order in the following table array.
As Fig. 4, store node instance in example array L, be respectively A, B, C and D.Stored respectively the subscript of above-mentioned each node instance in corresponding subscript array L ＇, having comprised: 0,1,2 and 3.
Also configured a chained list and be used for controlling described subscript array L ＇, the headers and footers that can configure described chained list when initial points to respectively first subscript 0 and last subscript 3 in subscript array L ＇.Then can obtain subscript in subscript array L ＇ by described chained list, and then definite node instance, the distribution of TEIDC completed.
Therefore, describedly obtain a node instance from the example array, comprising:
Step 301 is obtained the chained list corresponding with described subscript array.
Adopt the subscript of each node instance in subscript array admin instance array, therefore, can also configure the chained list corresponding with described following table array, adopt the headers and footers of described chained list point to respectively described following table array in a subscript.
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 is pointed to arbitrary subscript in the subscript array.As Fig. 4, chained list is under original state, and gauge outfit is pointed to the subscript of subscript 0(solid line indication), the table tail points to subscript 3.
Thereby when the distribution node example, at first obtain the chained list corresponding with described following table array.
Step 302 is obtained the subscript that described gauge outfit is pointed to, and determines corresponding node instance according to the subscript of obtaining.
Then can obtain the subscript of the gauge outfit sensing of described chained list, as obtain 0 in Fig. 4, just can get the value of TEIDC this moment, but TEIDC will possess corresponding relation with contextual information, therefore, also to according to described subscript, search node instance corresponding to this subscript, i.e. the node instance A of 0 correspondence in the example array.
Step 303 keeps the table tail of described chained list motionless, with subscript after the described lower target of obtaining of described gauge outfit sensing.
As Fig. 4, keep the sensing 3 of table tail motionless, with the subscript of gauge outfit by the next subscript 1(dotted line indication of sensing 0).Thereby completed the obtaining step of node instance.
At this moment, 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, efficient is higher.And can be with the value of TEIDC in the node instance subscript as this node instance, then adopt the subscript of each node instance in subscript array admin instance array, thus can determine fast the value of TEIDC.
Step 105 distributes contextual information in request to carry out the index of contextual information in described node instance and described node related, to distribute described node instance;
After the node instance of determining to distribute, can obtain the index of described contextual information from described node instance, then node can be distributed the contextual information that carries in request, carry out related with the index of contextual information in described node instance, thereby set up the corresponding relation of TEIDC and contextual information, completed the distribution of node instance.
