Abstract: A method for updating identity information of a packet gateway, an authentication, authorization, and accounting (AAA) server and a packet gateway. The method includes: 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; the decision-making network element deciding whether to update identity information of the packet gateway or not according to the UE capability indication information carried in the message and/or local information. The technical solution can be applied to distinguish R11 UE and R12 UE, and to ensure supporting both the R11 UE and the R12 UE normally accessing to a 3GPP core network through a 3GPP access system and a non-3GPP access system simultaneously.

Abstract: Provided are a method for optimizing the multicast group and an anchor. A set of nodes requesting for the same multicast group data and sharing the same Access Gateway (AG) is identified in a multicast group, and the same multicast group data is transmitted to each node in the set of nodes via the same AG thereby forwarding multicast data to different nodes via the same gateway, saving traffic of a network side, and optimizing the multicast group. In addition, the node optimization method allows the anchor to optimize multicast routing of the nodes requesting for the same multicast group data and sharing the same AG to the same shared gateway for forwarding if a node has a plurality of access interfaces in the present application.

Abstract: A method, device and system for managing a packet data network type management are disclosed. The method comprises: a User Equipment, UE, sends a request message to a WLAN AN, wherein the request message carries a packet data network type requested by the UE; the UE receives an acknowledgement message returned by the WLAN AN to the UE, wherein the acknowledgement message carries a packet data network type decided by a network side. It is solved the technical problem in the related art of the waste of the address resources, which is caused by the fact that the addresses corresponding to the packet data network type subscribed by the user in the subscription information are all directly allocated to the UE in advance, thereby achieving the technical effects of reducing the wasted address resources and improving the address resource utilization rate.
