Embodiment Construction

[0057] In order to solve the problem in the prior art that the communication quality is already very poor and the call quality is poor due to the failure to switch to the WCDMA network, the present invention provides a voice service switching method. The present invention is further described below in conjunction with the accompanying drawings and embodiments Detailed description. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] like figure 1 As shown, the voice service switching method may include the following steps:

[0059] Step 101: Acquiring the voice quality of the current VOLTE call;

[0060]Considering that when the call quality is severely degraded, there are some obvious voice characteristics, such as: intermittent voice, user repeated calls, in this example, the degree of voice quality degradation can be judged by voice recognition technology, which is...

Abstract

The invention discloses a voice service switching method and a voice service switching device, wherein the method comprises the following steps: acquiring voice quality of a current VOLTE call; determining a measurement indifference value of a LTE cell signal according to the voice quality; determining whether the measurement indifference value satisfies requirements of sending a measurement report, if so, sending the measurement report to a network side, thereby triggering switching to a WCDMA network. With the method and the device, a problem of relatively poor call quality caused by refusing to switch to the WCDMA network even if the call quality is already very poor in the existing technology is solved, and technical effects of effectively guaranteeing call quality and improving user experience are achieved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a voice service switching method and device. Background technique [0002] SRVCC (Single Radio Voice Call Continuity, single radio voice continuity scheme) is a VoLTE (Voice over LTE, an IP data transmission technology) voice service continuity scheme proposed by 3GPP, mainly for single radio frequency UE (user When the terminal) moves between the LTE / Pre-LTE network and the 2G / 3G CS network, the continuity of the voice call is guaranteed, that is, the smooth handover between the IMS-controlled VoIP voice and the CS domain voice of the single-radio UE is guaranteed. [0003] However, the handover threshold configurations currently configured in E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, evolved UMTS terrestrial radio access network) in different areas are slightly different. In some areas, the handover threshold is too low, which will cause SRVCC to lag behind. T...
