Fig. 1 is a packet data protocol context activation method flow diagram in the embodiment of the invention, as shown in Figure 1, comprises the steps:
Step 100 receives the PDP context activation solicited message, carries APN information in the described request information;
When the user uses Packet Service by MS, at first to activate PDP Context, by the bearer path of setting up, send the PDP context activation solicited message to SGSN, carry APN information in the described PDP context activation solicited message; SGSN receives the PDP context activation solicited message of the APN information that includes of MS transmission.
Step 101 is mated described APN information and subscription data information, if coupling is unsuccessful, then according to the access-in point information in the subscription data APN information of carrying in the request message is corrected;
After the PDP context activation solicited message of the APN information that includes that SGSN reception MS sends, judge whether described APN information can effectively be used, promptly judge this APN information whether with subscription data information in APN information be complementary, SGSN uses the GGSN corresponding with the APN selection of APN information matches success in the subscription data information and finishes activation.When MS carried out network attachment, SGSN obtained user's subscription data information from HLR, had comprised the APN information that the user contracts in this information.SGSN mates the information in APN in the solicited message and the subscription data information, if the match is successful, then the APN information in the application request message is finished follow-up activation; If coupling is unsuccessful, then use subscription data information the APN information in the solicited message is corrected, it is corrected as the APN that can finish follow-up activation.
Step 102 is used described access points information through correction and is carried out pdp context activation.
After SGSN corrected end to the APN information in the solicited message, the GGSN that uses the APN Information Selection correspondence of process correction finished activation.
Further, be not complementary if judge the APN information learn in the solicited message and the APN information in the subscription data information in the step 101, the described APN information in the solicited message that is meant that is not complementary can not be mated fully with the APN information in the subscription data information, then can be according to longest match principle, the access points information of using in the described subscription data information is corrected the access points information that comprises in the solicited message, be specially, for example the signatory APN information of user is " APN1 " in the subscription data information that obtains from HLR of SGSN, if the user on MS with the access points information errors be set to " AP ", and use " AP " to activate request as access points, then when SGSN receive comprise this solicited message after, the CAMEL-Subscription-Information of using in " AP " and the subscription data information " APN1 " carries out matching process, but because CAMEL-Subscription-Information " APN1 " in the subscription data information and the AP in the solicited message do not match, then SGSN uses " APN1 " in the subscription data information that APN information wrong in the solicited message is corrected, be about to it and be corrected as CAMEL-Subscription-Information " APN1 ", SGSN uses the address through " APN1 " inquiry GGSN that corrects then, and use " APN1 " to send to activate according to the address of GGSN and ask, finish the activation of PDP Context at last to GGSN.If the user is not only signatory with " APN1 " in the subscription data information that SGSN obtains from HLR, also contract with " APN11 ", then when the APN information of mistake is corrected, should use " APN11 " in the CAMEL-Subscription-Information that " AP " of mistake corrected according to longest match principle, " APN1 " and " APN11 " are promptly arranged in CAMEL-Subscription-Information, then preferentially select " APN11 " to carry out error correcting.Certainly, also can select for use other matching principle to mate in the present embodiment, for example the matching way used always of those skilled in the art such as short matching principle.Be not complementary if judge the APN information learn in the solicited message and the information in the subscription data information in the step 101, can also basis be the priority of access points information setting in the subscription data information, using described CAMEL-Subscription-Information corrects the access points information that comprises in the solicited message, be specially, on SGSN, the signatory APN in the subscription data information is carried out the priority configuration, when SGSN finds that APN information in the solicited message that MS sends and the CAMEL-Subscription-Information in the subscription data information do not match, then correct according to the APN of the highest signatory APN information of CAMEL-Subscription-Information medium priority to mistake, for example, comprise in user's the CAMEL-Subscription-Information " APN1 ", " APN2 ", " APN3 " and " APN4 ", the priority of above-mentioned signatory APN is configured to 1 respectively, 2,3 and 3, the more little expression priority of its intermediate value is high more.User's signatory APN is " APN1 " and " APN2 ", APN information or activation solicited message that mistake is set on user's MS are not carried APN information, then SGSN will use CAMEL-Subscription-Information to correct, priority difference because of signatory APN, the priority 1 of " APN1 ", the priority of " APN2 " are 2, and the priority of " APN1 " is higher than " APN2 ", then " APN1 " that SGSN selection priority is high corrects the APN of mistake, and correcting the result is " APN1 ".If the priority of user's signatory APN is identical, then select the first signatory APN to correct, for example, user's signatory APN is " APN3 " and " APN4 ", its priority is identical to be 3, then SGSN should select first signatory APN " APN3 " to correct when carrying out the APN correction, and correcting the result is " APN3 ".Certainly, the signatory APN information that also optional usefulness has other priority among this embodiment is corrected, and the signatory APN that for example can use time limit priority corrects.
If being " APN1 " and open country, blocks the signatory APN of user in the step 101, then when user error ground setting " APN2 " activates request, SGSN is considered as non-signatory APN with it, and can use signatory " APN1 " to correct according to above-mentioned correction principle, use " APN1 " to carry out activation process, after activating successfully, the APN that writes down in this user's the ticket is " APN1 ".Again because the signatory wild card of user, therefore can think that " APN2 " can match wild card, then " APN2 " do not corrected, and use APNA2 and carry out dns resolution, searching to be with uses behind the corresponding GGSN address " APN2 " to initiate to activate request to GGSN, after activating successfully, the APN that writes down in user's the ticket is " APN2 ".When if dns resolution is carried out in application " APN2 ", all not configurations " APN2 " on hosts file of SGSN this locality and the dns server, cause the dns resolution failure, can use this moment SGSN to go up acquiescence APN and carry out dns resolution once more, after carrying out dns resolution and obtain corresponding GGSN address by acquiescence APN, use acquiescence APN to initiate to activate request, finish pdp context activation at last to GGSN." hosts " file of SGSN is the home domain name resolution file, is a file of record domain name and IP address corresponding relation, and the IP address that disposes in the local hosts file is preferentially inquired about by system.This document for example all exists among windows and the unix in a lot of systems, and actual name may difference, all is " hosts " or " hostfile " usually.
