Embodiment Construction

[0034] 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.

[0035] The embodiment of the present invention provides a mode switching method, such as figure 1 shown, including:

[0036] 101. When a UE (User Equipment, user equipment) is in a state of accessing a first network through a first network mode of a first communication mode, the UE determines whether the first network supports a first subsystem.

[0037] Wherein, the first network mode of the first communication mode is used to support the UE to access a firs...

Abstract

The embodiment of the invention provides a method and device for switching modes, and relates to the field of communication. The method and device are used for improving the user experience. The method comprises the steps that when user equipment (UE) is in the state of being connected to a first network through a first network mode of a first communication mode, the UE determines whether the first network supports a first subsystem or not; if the UE determines that the first network does not support the first subsystem, and when the UE is connected to a second network not through the first communication mode, the UE starts a second communication mode and is connected to the second network through the second communication mode; the UE sends first register request information to the second network. The method and device are suitable for service transmission scenes.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for mode switching. Background technique [0002] VoLTE (Voice over Long Term Evolution, long-term evolution network voice service) is a multimedia subsystem based on the IMS (Internet Protocol Multimedia Subsystem) protocol defined by the 3GPP (3rd Generation Partnership Evolution, Third Generation Partnership Project) standard. ) voice services. In an LTE (Long Term Evolution, long-term evolution) network, VoLTE voice data can be transmitted as IP (Internet Protocol, a protocol for interconnection between networks) data. Compared with the voice services in the existing 2G (2nd Generation Mobile Communications System, second-generation mobile communication system) and 3G (3rd Generation Mobile Communications System, third-generation mobile communication system) networks, VoLTE introduces high-definition codec and other technologies , so that the call conne...
