Abstract
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.
Claims20
A method for user detachment when a handover or change occurs between a 3GPP network and a non-3GPP network, comprising:
- handing over or switching a user equipment (UE) from a source network to a target network;
- and
- determining, by a network element on a network side, whether to detach the UE from the source network;
- if yes, detaching the UE from the source network.
A method for user detachment when a handover or change occurs in a heterogeneous network, comprising:
- initiating, by a user equipment (UE), handover or switching from a source network to a target network;
- and
- determining, by the UE, whether to detach the UE from the source network;
- if yes, detaching the UE from the source network.
A system for user detachment when a handover or change occurs in a heterogeneous network, comprising a network side, wherein
- the network side is adapted to handover or changed the UE from the source network to the target network and to detach the UE from the source network.
A device for user detachment when a handover or change occurs in a heterogeneous network, comprising a second handover or change module and a second detachment module disposed on a network side;
- wherein
- the second handover or change module is adapted to hand over or switch a user equipment (UE) from a source network on the network side to a target network on the network side;
- and
- the second detachment module is adapted to detach the UE from the source network.
A device for user detachment when a handover or change occurs in a heterogeneous network, comprising a first handover or change module and a first detachment module disposed in a user equipment (UE);
- wherein
- the first handover or change module is adapted to hand over or switch the UE from a source network to a target network;
- and
- the first detachment module is adapted to detach the UE from the source network.
