METHOD, SYSTEM, AND DEVICE FOR USER DETACHMENT WHEN A HANDOVER OR CHANGE OCCURS IN HETEROGENEOUS NETWORK

摘要

A method for user detachment when a handover or change occurs in a heterogeneous network is provided. The method includes: a user equipment (UE) is handed over or switched from a source network to a target network; a network element on a network side determines whether to detach the UE from the source network, and if yes, the network element on the network side detaches the UE from the source network. A system and a device for user detachment when a handover or change occurs in a heterogeneous network, and another method for user detachment when a handover or change occurs in a heterogeneous network are also provided.
