Abstract

The embodiment of the invention provides a call method of a mobile terminal and the mobile terminal. The method comprises a step of judging whether the network to which the mobile terminal attached is an LTE special network, a step of receiving the voice call request of a user when the network to which the mobile terminal attached is the LTE special network, a step of responding to the voice call request and obtaining an SIB7 system message, a step of extracting the GSM special network frequency point information in the SIB7 system message, a step of switching to a GSM special network according to the GSM special network frequency point information, and a step of using the GSM special network to trigger voice call. The GSM special network frequency point information in the SIB7 system message is used to substitute the GSM special network frequency point information of a base station side, the problem that RRC connection release is failed to obtain to obtain a GSM special network frequency point in a CSFB process and the connection of the GSM special network is failed is solved, the opportunity of accessing the GSM network of the mobile terminal is improved, and the call quality of the user is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a mobile terminal call method and the mobile terminal. Background technique [0002] The mobile network coverage of the high-speed railway is divided into private network and public network. The private network is a community specially set up along the high-speed railway track. After the optimization strategy of the high-speed railway private network optimization strategy, the signal of the mobile terminal registered in the private network is relatively stable. . The public network is an ordinary residential area around the high-speed railway, which has not been optimized, and the signal of the mobile terminal registered in the public network changes drastically and is unstable. The actual signal environment on the high-speed railway is mixed coverage of private network and public network. The performance of the mobile terminal registered in the private net...
