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.
Claims17
A method for controlling network handover of a user equipment (UE) comprising:
- obtaining, by a mobile management entity (MME), information of a user type of a UE from a serving GPRS support node (SGSN);
- determining, by the MME, which type of universal integrated circuit card (UICC) the UE is equipped with according to the obtained information of the user type of the UE;
- and
- determining, by the MME, whether to perform a handover of the UE during relocation to an evolved universal mobile telecommunication system terrestrial radio access network (eUTRAN), based on the determined type of UICC the UE is equipped with.
A mobile management entity (MME), comprising:
- an obtaining module, configured to obtain information of a user type of a user equipment (UE) from a serving GPRS support node (SGSN);
- and
- a processing module, configured to determine, which type of universal integrated circuit card (UICC) the UE is equipped with according to the obtained information of the user type of the UE;
- and to determine whether to perform a handover of the UE to an evolved universal mobile telecommunication system terrestrial radio access network (eUTRAN), based on the determined type of UICC the UE is equipped with.
A system, comprising a mobile management entity (MME) and a serving GPRS support node (SGSN), wherein the MME comprises hardware for:
- an obtaining module, configured to obtain information of a user type of a user equipment (UE) from the SGSN;
- and
- a processing module, configured to determine, which type of universal integrated circuit card (UICC) the UE is equipped with according to the obtained information of the user type of the UE;
- and to determine whether to perform a handover of the UE to an evolved universal mobile telecommunication system terrestrial radio access network (eUTRAN), based on the determined type of UICC the UE is equipped with.
A system, comprising a mobile management entity (MME) and a user equipment, (UE), wherein the MME comprises hardware for:
- an obtaining module, configured to obtain information of a user type of the UE from a serving GPRS support node (SGSN);
- and
- a processing module, configured to determine, which type of universal integrated circuit card (UICC), the UE is equipped with according to the obtained information of the user type of the UE;
- and to determine whether to perform a handover of the UE to an evolved universal mobile telecommunication system terrestrial radio access network (eUTRAN), based on the determined type of UICC the UE is equipped with.
