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.

1. In a mobility management entity (MME) of a 3rd Generation Partnership Project (3GPP) network, a method for releasing resources utilized by a User Equipment (UE) when handed over from the 3GPP network and a non-3GPP network, comprising:
receiving a delete bearer request sent by a serving gateway (GW) in the 3GPP network, wherein the delete bearer request includes an indication of a handover of the UE from the 3GPP network to the non-3GPP network; in response to the delete bearer request, deleting at least one bearer resource and verifying that all bearer resources associated with the UE have been deleted; determining that a terminal capability of the UE is single radio capability; and based on the determination, detaching the UE from the 3GPP network without sending a detach request message to the UE.
