Claim:
1. A method for updating identity information of a packet gateway, comprising: a decision-making network element receiving a message which carries user equipment (UE) capability indication information and is sent by an information transmission network element; and the decision network element deciding whether to update the identity information of the packet gateway or not according to the UE capability indication information carried in the message and/or local information; wherein, the step of the decision-making network element receiving the message which carries the UE capability indication information and is sent by the information transmission network element comprises: an authentication, authorization, and accounting (AAA) server receiving an Extensible Authentication Protocol (EAP) authentication message which carries the UE capability indication information and is sent by a trusted non-3GPP access network (TNAN) network element; or the AAA server receiving a packet gateway address update message which carries the UE capability indication information and is sent by the packet gateway, wherein, the packet gateway acquires the UE capability indication information from a session creation request message or a proxy binding update message sent by the TNAN network element; or the packet gateway receiving the session creation request message or the proxy binding update message which is transmitted by the TNAN network element and carries the UE capability indication information; wherein, when the decision-making network element is the AAA server, the step of the decision-making network element deciding whether to update the identity information of the packet gateway or not according to the UE capability indication information carried in the message and/or the local information comprises: when the AAA server determines that a current UE is a R12 UE and is in a handover procedure according to the UE capability indication information and/or the local information, do not update the address of the P-GW or the GGSN to a Home Subscriber Server (HSS); when the AAA server determines that the current UE is a R12 UE and accesses for the first time according to the UE capability indication information and/or the local information, update the address of the P-GW or the GGSN to the HSS; or when the AAA server determines that the current UE is a R11 UE according to the UE capability indication information and/or the local information, do not update the address of the P-GW or the GGSN to the HSS; when the decision-making network element is the packet gateway, the step of the decision-making network element deciding whether to update the identity information of the packet gateway or not according to the UE capability indication information carried in the message and/or the local information comprises: when the packet gateway determines that the current UE is a R12 UE and is in the handover procedure according to the UE capability indication information and/or the local information, do not update the address of the packet gateway to the AAA server or the HSS; when the packet gateway determines that the current UE is a R12 UE and accesses for the first time according to the UE the capability indication information and/or the local information, update the address of the packet gateway to the HSS or the AAA server; or when the packet gateway determines that the current UE is a R11 UE according to the UE capability indication information and/or the local information, do not update the address of the packet gateway to the HSS or the AAA server.
