The 3rd receiver module is used to receive the PDP Context foundation response that GGSN sends;
Module is returned in second response, is used for returning described PDP Context to SGSN and sets up response.
Therefore, in implementation two, in the step 22, the 3rd packet data protocol PDP Context that GGSN sends from the network insertion control device is set up the request and is directly obtained described the 3rd APN, and described the 3rd APN is selected from least two the 2nd APN corresponding with a described APN that self preserve according to preset rules by the network insertion control device.
Simultaneously, in implementation two, in the step 23, GGSN need return PDP Context to mobile communication terminal by network insertion control device and SGSN and set up response.
As shown in Figure 6, be the detailed process schematic diagram of method in the embodiment of the invention, it comprises:
When portable terminal need be got online without being tethered to a cable, initiate the PDP context activation request to SGSN based on predefined APN configuration parameter.Generally comprise APN information in this activation request,, then fill up according to the 3GPP standard by SGSN if be empty.
APN on the network insertion control device in the pre-configured signaling and the mapping relations table of the 2nd APN, different request APN separate configurations mapping relations table are by the mapping acquisition route APN result of request APN with route APN tabulation;
Step 611, GGSN inserts outer data network according to the route plane of the 3rd APN correspondence.
Certainly, among Fig. 6, GGSN receives also needs to carry out the PDP context activation processing after PDP Context is set up request, only not shown.
Below mapping ruler in the embodiment of the invention and mapping relations being elaborated, in follow-up explanation, is that example is elaborated with first kind of implementation only.
As shown in the table, be a kind of corresponding relation allocation list that can use in the embodiment of the invention.
Can find that according to last table an APN (APN-A) is corresponding with 3 the 2nd APN (APN-A, APN-B and APN-C), and preset rules wherein is a poll.
In this situation, suppose user A, B and C successively send the PDP context activation request, wherein all comprise APN-A, in this case, after GGSN receives first PDP Context that comprises APN-A foundation request, according to the poll rule from APN-A, select APN-A among APN-B and the APN-C, utilize the route plane of APN-A correspondence to be linked into external network then, and GGSN receives after another PDP Context that comprises APN-A sets up request, according to the poll rule from APN-A, select APN-B among APN-B and the APN-C, utilize the route plane of APN-B correspondence that user B is linked into external network then, and GGSN receives after another PDP Context that comprises APN-A sets up request, according to the poll rule from APN-A, select APN-C among APN-B and the APN-C, utilize the route plane of APN-C correspondence to be linked into external network then.
In this case, can realize the load sharing on multirouting plane.
For above-mentioned corresponding relation allocation list, break down or be unusual or need to safeguard in the route plane of any one APN correspondence, at this moment, this APN deleted from tabulation gets final product, and is described as follows.
Suppose when data link in the route plane of APN-B correspondence need be checked that with APN-B deletion from tabulation, this moment, remaining table was as follows.
In this situation, suppose user A, B and C successively send the PDP context activation request, wherein all comprise APN-A, in this case, after GGSN receives the PDP Context foundation request that comprises APN-A, from APN-A and APN-C, select APN-A according to the poll rule, utilize the route plane of APN-A correspondence to be linked into external network then, and GGSN receives after the next one comprises the request of setting up of the PDP Context of APN-A, from APN-A and APN-C, select APN-C according to the poll rule, utilize the route plane of APN-C correspondence to be linked into external network then, and GGSN receives after another PDP Context that comprises APN-A sets up request, from APN-A and APN-C, select APN-A according to the poll rule, utilize the route plane of APN-A correspondence to be linked into external network then.
Therefore, utilize a plurality of routes plane to insert same external network, realized the backup that inserts, thereby break down on the route plane of any one APN correspondence or unusual or need to safeguard, can not exert an influence existing business.
Certainly, above-mentioned poll rule also can be other rule, as the principle of determining according to priority, as the principle according to the state on the route plane of APN correspondence, be unusual or during obstruction as the state on the route plane of APN correspondence, excludes selective listing.
Certainly, can also distribute the 2nd APN according to its terminal iidentification for it for having the terminal of identical APN, each terminal iidentification is corresponding to one the 2nd APN.
Therefore, the preset rules in the embodiment of the invention can be:
According to the state on the route plane of the 2nd APN correspondence, selection mode is the APN of the route plane correspondence of work; Perhaps
Poll the 2nd APN; Perhaps
Select the 2nd the highest APN of priority; Perhaps
Select two APN corresponding with terminal iidentification.
Certainly, the external network in the embodiment of the invention can be outer data network or INTERNET.
Suppose that APN-A is corresponding to APN-A, APN-B and APN-C, wherein APN-A, APN-B are corresponding to the route plane A and the B that are linked into outer data network A, and APN-C is corresponding to the route plane C that is linked into outer data network B, preset rules is mobile communication terminal 1 and APN-A simultaneously, the APN-B correspondence, mobile communication terminal 2 and APN-B, the APN-C correspondence, mobile communication terminal 3 is corresponding with APN-C, terminal 1 is corresponding to polling selection mode, terminal 2 is corresponding to priority, and the form of foregoing description correspondence is as follows:
According to the network of above-mentioned corresponding relation as shown in Figure 7.
In this case, after GGSN receives the PDP Context that the comprises APN-A request of setting up, wherein go back the terminal iidentification of carried terminal 1, selecting one this moment from APN-A or APN-B inserts, even one of them route plane goes wrong, can also select this moment another to insert external network A, after GGSN receives the PDP Context that the comprises APN-A request of setting up, wherein go back the terminal iidentification of carried terminal 2, from APN-B and APN-C, select the highest the inserting of priority this moment, even one of them route plane goes wrong, can also select another to insert another external network this moment.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
