Abstract
A method, a system and a device for maintaining user service continuity are provided in an embodiment of the present invention. The method includes prohibiting a UE from accessing a forbidden network before handover is complete when the UE needs to perform network handover if the UE adopts a SIM access technology, thus avoiding service interruption of a SIM user due to access to an incorrect network. A system and a device for maintaining user service continuity are provided in an embodiment of the present invention.
Claims25
A method for maintaining user service continuity, comprising:
- when a User Equipment (UE) needs to perform network handover, prohibiting the UE from accessing a forbidden network, by a Radio Network Controller (RNC) at a network side, before the network handover is complete if the UE adopts a Subscriber Identity Module (SIM) technology for access;
- and
- selecting, by the RNC, an accessible target network for the UE.
A method for maintaining user service continuity, comprising:
- when a User Equipment (UE) needs to perform network handover, prohibiting the UE from accessing a forbidden network, by a Mobile Management Entity (MME) at a network side, before the network handover is complete if the UE adopts a Subscriber Identity Module (SIM) technology for access;
- and
- selecting, by a Radio Network Controller (RNC), an accessible target network for the UE.
A device for maintaining user service continuity, comprising:
- a judging unit, configured to judge whether a User Equipment (UE) is a Subscriber Identity Module (SIM) user when the UE needs to perform network handover;
- and
- a handling unit, configured to prohibit the UE from accessing a forbidden network before the network handover is complete when the judging unit determines that the UE is the SIM user.
A system for maintaining user service continuity, comprising:
- a Mobile Management Entity (MME), configured to judge whether a User Equipment (UE) is a Subscriber Identity Module (SIM) user when the UE needs to perform network handover;
- and prohibit the UE from accessing a forbidden network before the network handover is complete;
- and
- a Radio Network Controller (RNC), configured to select an accessible target network for the UE.
