Communication network switching method and mobile terminal

Abstract

The embodiment of the invention discloses a communication network switching method and a mobile terminal. The method comprises the following steps: receiving a measurement event issued by a network; acquiring an appointed threshold value in a GSM signal in the measurement event; and measuring the LTE signal intensity of the current service cell and the GSM signal intensity of an adjacent service cell; judging whether the LTE signal intensity is less than the preset threshold value; reporting a first measurement report to the network if the LTE signal intensity is less than the preset threshold value, wherein the GSM signal intensity in the first measurement report is the actual measurement value; reporting a second measurement report to the network if the LTE signal intensity is not less than the preset threshold value, wherein the GSM signal in the second measurement report is the preset intensity value, and the preset intensity value is less than the appointed threshold value. By use of the method disclosed by the invention, whether to change the GSM signal intensity to the preset intensity value slightly less than the appointed threshold value in the reported measurement report is decided according to the LTE signal intensity so as to meet a conventional SRVCC switching condition; the switching of the terminal is less frequent and a configuration requirement issued by the network is satisfied.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a communication network switching method and a mobile terminal. Background technique [0002] As operators continue to build LTE networks. More and more places have already covered LTE. The LTE network can provide hundreds of megabits of data transmission rate, which is completely sufficient for traditional voice transmission, and then can undertake the transmission of high-definition digital voice and high-definition digital voice, which require higher transmission rates. Data in the form of multimedia such as video. Although we can use VOLTE technology to transmit these multimedia data under the LTE network, in areas without LTE network, we still can only use traditional analog data to form voice data for transmission through analog-to-digital conversion, so when we use VOLTE for high-definition During voice or video calls, when moving to the edge of LTE network cove...

Problems solved by technology

[0003] However, due to unilateral reasons of the network, sometimes the network sends wrong handover evaluation measurement events or the network does not issue handover instructions after receiving the measurement report reported by the terminal, which will cause the terminal to switch from LTE to LTE frequently and too quickly.
