PACKET DATA NETWORK TYPE MANAGEMENT METHOD, DEVICE, AND SYSTEM

摘要

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.
