Abstract

A method and an apparatus for controlling issuance of a PDP context. The method includes: receiving a GPRS location updating request of a user sent by an SGSN; acquiring, according to the GPRS location updating request, an issuance control condition of a PDP context to which the user has subscribed; and determining, according to the issuance control condition, whether to send the PDP context to the SGSN. According to the method and the apparatus for controlling issuance of a PDP context in the embodiments of the present disclosure, issuance of a PDP context is controlled based on an issuance control condition of the PDP context, which can avoid generation of unnecessary traffic, improve service experience of a user, and reduce the customer service workload of an operator, thereby lowering the operating cost of the operator.

Claims

1. A method for controlling issuance of a packet data protocol (PDP) context, comprising:

receiving a general packet radio service (GPRS) location updating request of a user sent by a serving general packet radio service support node (SGSN);

wherein the location updating request carries information of the user and an identity (ID) of the SGSN;

determining, according to the ID of the SGSN, a network the user currently accesses;

acquiring, according to the information of the user, an issuance control condition of a PDP context to which the user has subscribed; and

determining, according to the network the user currently accesses and a network range of issuance indicated by the issuance control condition, whether to send the PDP context to the SGSN.

2. The method according to claim 1, wherein the network the user currently accesses is a national home public land mobile network (PLMN), another national PLMN, an international home PLMN, or another international PLMN.

3. The method according to claim 1, wherein a control option of the issuance control condition is one selected from the group consisting of:

issuance on other international public land mobile networks (PLMNs) only, issuance on international home PLMNs only, issuance during international roaming only, issuance on other national PLMNs only, issuance on other PLMNs only, issuance on other national PLMNs and international home PLMNs only, issuance on all PLMNs except national home PLMNs, issuance on national home PLMNs only, issuance on national home PLMNs and other international PLMNs only, issuance on home PLMNs only, issuance on all PLMNs except other national PLMNs, issuance inside a local country only, issuance on all PLMNs except international home PLMNs, and issuance on all PLMNs except other international PLMNs.

4. The method according to claim 1, wherein the method further comprises sending a GPRS not subscribed error response to the SGSN when it is determined that no PDP context to which the user has subscribed needs to be sent.

5. An apparatus for controlling issuance of a packet data protocol (PDP) context, comprising a processor;

and a non-transitory computer readable medium having a plurality of computer readable instructions stored thereon that, when executed by the processor, cause the processor to;

receive a general packet radio service (GPRS) location updating request of a user sent by a serving general packet radio service support node (SGSN);

wherein the location updating request carries information of the user and an identity (ID) of the SGSN;

determine, according to the ID of the SGSN, a network the user currently accesses;

acquire, according to the information of the user, an issuance control condition of a PDP context to which the user has subscribed; and

determine, according to the network the user currently accesses and a network range of issuance indicated by the issuance control condition, whether to send the PDP context to the SGSN.

6. The apparatus according to claim 5, wherein the network the user currently accesses is a national home public land mobile network (PLMN), another national PLMN, an international home PLMN, or another international PLMN.

7. The apparatus according to claim 5, wherein a control option of the issuance control condition is one selected from the group consisting of:

issuance on other international public land mobile networks (PLMNs) only, issuance on international home PLMNs only, issuance during international roaming only, issuance on other national PLMNs only, issuance on other PLMNs only, issuance on other national PLMNs and international home PLMNs only, issuance on all PLMNs except national home PLMNs, issuance on national home PLMNs only, issuance on national home PLMNs and other international PLMNs only, issuance on home PLMNs only, issuance on all PLMNs except other national PLMNs, issuance inside a local country only, issuance on all PLMNs except international home PLMNs, and issuance on all PLMNs except other international PLMNs.

8. The apparatus according to claim 5, wherein the apparatus comprises a home location register (HLR).
