Embodiment Construction

[0042] The basic idea of ​​the embodiment of the present invention is that an eNB (evolved Node B, evolved Node B, referred to as a base station) acquires PS HO capability information of an adjacent GERAN cell in various ways, including supporting PS HO and not supporting PS HO, and then when When the UE initiates a CS voice service in the Active state, it receives the CS voice service, and determines the handover process according to the target system cell type and PSHO capability of the service, so that the handover process can be effectively judged and optimized, and the handover delay can be reduced. , to avoid switching failures.

[0043] It should be noted that, in the current prior art, when the target system cell of the CS voice service is a UTRAN cell, the UTRAN cell supports PS HO by default; Types (including UTRAN and GERAN) and PS HO capability information (supporting PS HO or not supporting PS HO) to determine the switching mode, only need to focus on how to obtai...

Abstract

The invention relates to a method for realizing service switching between different networks and a device therefor, wherein the method comprises: acquiring PS HO capability information of adjacent GERAN districts; and realizing the switching according to the district type and the PS HO capability of a target system of a CS voice service when the CS voice service initiated by a UE is received. With the adoption of the method and the device, by acquiring the PS HO capability information containing supporting PS HO and non-supporting PS HO of the adjacent GERAN districts and then by receiving the CS voice service when the UE initiates the CS voice service under the Active state, the switched flows can be determined according to the district type and the PS HO capability of the target system of the service, so as to effectively judge and optimize the switching process, reduce the switching time-delay and avoid the switching failure.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a device for realizing service switching between different networks. Background technique [0002] The CS fallback (circuit domain fallback) feature in the LTE (Long Term Evolution, long-term evolution) system provides voice and other CS domain services for users accessing the EPC (Evolved Packet Core, evolved core network) system by reusing the CS architecture . When a user initiates a CS voice service in the EUTRAN (Evolved UMTS Terrestrial Radio Access, evolved UMTS terrestrial radio access) network, or receives a voice service from the CS domain, the user needs to be switched to the UTRAN (UMTS Terrestrial Radio Access, UMTS Terrestrial Radio Access) or GERAN (GSM / EDGE Radio Access Network, GSM / EDGE Radio Access Network) network to establish CS domain services. [0003] Although there are many handover methods in the current prior art, for example,...
