US 8,411,673 B2 · Method, device, and system for transferring service control signalling path

Abstract

A method, device, and system for transferring a Service Control Signalling Path are provided. The method for transferring a Service Control Signalling Path includes: establishing a connection with an opposite end by a User Equipment (UE), where the UE uses a Circuit Switched (CS) bearer in a CS network and a Service Control Signalling Path in a first Packet Switched (PS) network; sending a transfer request via a second PS network, to instruct a network side to transfer the Service Control Signalling Path according to the transfer request. Thus, the UE can replace a current Gm reference point with a Gm reference point of a new and available PS network when the PS network where the current Gm reference point is located is unavailable, so as to ensure smooth data transmission.

A method for transferring a Service Control Signalling Path, comprising:

establishing, by a User Equipment (UE), a connection with an opposite end, wherein the UE uses a Circuit Switched (CS) bearer in a CS network and the Service Control Signalling Path in a first Packet Switched (PS) network;
and
sending a transfer request via a second PS network to instruct a network side to transfer the Service Control Signalling Path according to the transfer request,
wherein the UE retains the CS bearer in the CS network after the network side transfers the Service Control Signalling Path.
