Embodiment Construction

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0060] In the present invention, when the UE's serving cell initiates a voice call and switches from the original network to the GSM network, the UE sends first indication information to the GSM network to instruct the GSM network to send a channel release signaling to the UE after the voice call ends, and the UE receives the channel release signaling. After releasing the instruction, perform cell measurement on the original network, obtain the measurement resu...

Abstract

The embodiment of the invention provides a method and device for quickly returning to an original network. UE sends first indication information to a GSM network to indicate the GSM network to send a channel release signal to the UE after a voice call is finished, after the UE receives the channel release signal, cell measurement is conducted on the original network, a measurement result is acquired, a first target cell of the original network to be returned is determined according to the measurement result, and then the UE returns to the first target cell of the original cell. By the adoption of the technical scheme, the GSM network does not need to be updated, the original network can be quickly returned after the voice call is finished, and network establishment cost is reduced.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and device for quickly returning to an original network. Background technique [0002] With the rapid development of wireless communication technology, although the new generation network after Global System for Mobile Communications (GSM) supports full packet switching network, it does not support voice services. Among them, the representative new A generation network such as: Time Division-Synchronous Code Division Multiple Access (TDS-SCDMA) network or Long Term Evolution (LTE) network, therefore, when the new generation To successfully develop voice services under the network, it is necessary to switch from the network being used by User Equipment (UE) to the GSM network. When the voice service ends, it is necessary to return to the original network (that is, the network used before switching to the GSM network) Continue to complete other b...
