Abstract

Provided in the present application are a method and a base station for implementing service initialisation redirection and switching. When a terminal UE initialises a service, detecting a random access procedure executed by the terminal, and triggering a redirection procedure; in the redirection procedure, redirecting the terminal to another target system, target frequency point, or target cell; thereafter, the terminal must re-initialise the service in the other target system, target frequency point, or target cell.

Description

Technical field [0001] The present invention relates to service initialization technology, in particular to a method and base station for realizing service initialization redirection and switching. Background technique [0002] There are many high interference scenarios in current communication networks, such as atmospheric duct interference, high load scenarios, and weak coverage scenarios. In these high-interference scenarios, the IMS-based voice service (VoLTE, Voice over LTE) may fail to initiate a call. [0003] Traditional technologies to solve the failure of initiating calls include: Single Radio Voice Call Continuity (SRVCC) before ringing (bSRVCC, Single Radio Voice Call Continuity (SRVCC) before ringing) technology when the VoLTE service initiates a call. Enhanced Single RadioVoice Call Continuity (eSRVCC, Enhanced Single RadioVoice Call Continuity) is moved to 2G initiation; in the VoLTE initiation process, intra-LTE system handover is performed, and users are switched ...
