Embodiment 1

[0176] Regarding the first embodiment, it should be noted that the separation method in this embodiment is also suitable for the processing of the UE switching / changing from the non-3GPP network to the 3GPP network:

[0177] Step 1, after the UE switches / changes to the 3GPP network, the PDN GW sends a binding revocation indication message to the non-3GPP network GW. The message carries the Cause cell, which indicates the reason for the revocation of the binding. For binding revocation caused by handover / change from non-3GPP network to 3GPP network, PDN GW sets the Cause cell to "UE's accessing RAT changed from Non-3GPP network to 3GPP network". For binding revocation caused by non-handover / change If the decision is cancelled, the PDN GW sets the Cause cell to another value.

[0178] Step 2, after receiving the binding revocation instruction message, the non-3GPP network GW deletes the bearer resource. If the non-3GPP network GW finds that all bearer resources of the UE are d...

Abstract

The embodiment of the invention discloses a method for user separation when a heterogeneous network switches or changes. The method comprises the following steps: a UE switches / changes from a source network into a target network; the source network determines whether to separate the UE from the source network: if yes, the UE is separated from the source network, otherwise the UE is not separated from the network. The embodiment of the invention further provides a system and a device for user separation when the heterogeneous network switches or changes, as well as another method for user separation when the heterogeneous network switches or changes. The separation scheme solves the problems that a network side separates the UE from the source network and the UE is separated from the network when the UE switches / changes from the source network to the target network.

Description

technical field [0001] The present invention relates to network communication technology, and in particular, to a method, system and device for user separation during switching / changing of heterogeneous networks. Background technique [0002] The 3rd Generation Partnership Project (3GPP, 3rd-Generation Partnership Project) network is studying a new evolution network in order to enhance the competitiveness of future networks. figure 1 It is a schematic diagram of the system structure of the 3GPP network evolution network. The system includes an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN, Evolved UMTS Terrestrial Radio Access Network), which is used to implement all functions related to the evolved network radio; a mobility management network element (MME, Mobility Management Entity), which is used for It is responsible for the mobility management of the control plane, including user context and mobility state management, as well as assigning user temporary identi...
