Problems solved by technology

[0006] In the process of 1xRTT CSFB or SRVCC, for the bearer of the UE, the SAE / LTE network releases the GBR bearer and suspends the Non-GBR bearer, so that the UE cannot continue to use the PS data service or can continue to use the PS service but the switching process time Longer, leading to poor user experience

Embodiment Construction

[0027] The specific implementation manners of the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0028] The embodiment of the present invention is mainly based on a CSFB (CS Fallback, voice fallback in CS domain) call flow. It should be noted that those skilled in the art should understand that for the CSFB called procedure, the processing procedure is similar, so details will not be repeated here.

[0029] Those skilled in the art should understand that, according to the technical solution provided by the implementation of the present invention, there can be similar or similar technical solutions applied to the CSFB process from LTE to 2G / 3G, or applied to SRVCC (Single Radio Voice Call Continuity single wireless voice Call Continuity) process, the above-mentioned technical solutions should be in the protection scope of the present invention.

[0030] In the following embodiments, if the target 1xRTT base station...

Abstract

The invention discloses a switching method and a switching device, which belong to the field of communication. The switching method comprises the following steps of: receiving indication information from a mobile management entity (MME), wherein the indication information is used for indicating whether a network side and a terminal support enhanced circuit system fallback (CSFB) to a 1x network or not; if the network side and the terminal support the enhanced CSFB, determining to execute the enhanced CSFB to the 1x network and switching operation to a high rate packet data (HRPD) network and transmitting a first message to the terminal so as to trigger the terminal to perform the enhanced CSFB to the 1x network and the switching operation to the HRPD network; and if the network side and / or the terminal do not support the enhanced CSFB to the 1x network, initiating the common CSFB or ending up the process. The method has the advantages of realizing that user equipment (UE) can continue to use packet system (PS) data service in the process of generating 1x radio transmission technology (RTT) CSFB or performing single radio voice call continuity (SRVCC), shortening the switching time and providing good client experience for a client.

Description

technical field [0001] The present invention relates to the communication field, in particular to a switching method and device. Background technique [0002] Currently, a Long Term Evolved (LTE for short) network / System Architecture Evolved (SAE for short hereinafter) network has become an important research topic. Among them, LTE aims to provide a network that can reduce delay, increase user data rate, improve system capacity and low-cost coverage. It uses packet (Packet System PS) domain services, and the bearer network is Internet Protocol (Internet Protocol, hereinafter referred to as : IP) bearer. [0003] It can be seen from the prior art that in the LTE system, voice service data is generally controlled by the IMS, so the voice service in SAE / LTE is generally called VoIP (Voice Over IP over IP) voice service. Traditional voice services are generally carried on CS TDM (Circuit System Time Division Multiplexing). The deployment of LTE in the initial stage is hotspot...
