Problems solved by technology

[0004] However, in some network configuration states, when a terminal supporting CSFB switches from a 4G network to a 2G or 3G network for voice services as a called party, voice service failures may occur
For example: the 4G network is not configured with 2G or 3G network adjacent cells, or, when the terminal performs CSFB joint registration, it registers the packet switching (Packet switching, abbreviated: PS) domain on the 4G network but does not register the circuit switching (PS) domain in the 2G or 3G network. Circuit Switch (abbreviation: CS) domain, or the location area of ​​the 4G network cell where the terminal is currently located is different from that of the 2G or 3G network cell; in the above network configuration state, when the terminal switches from the 4G network to the 2G or 3G network voice service failure

Abstract

A method and device for processing circuit switched fallback terminal communication. The method comprises: a terminal determining that a first 4G network cell is a CSFB called failure cell, wherein the CSFB called failure cell is a 4G network cell causing CSFB called failure due to a pre-set reason, and the first 4G network cell is a current serving cell of the terminal (S101); and when the terminal does not perform a data service, the terminal changing a registration network to a 2G or 3G network from a 4G network (S102). Thus, it is ensured that the terminal can successfully perform voice communication when serving as a called party, and the CSFB called call-completion rate is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for processing communication of a CS domain fallback terminal. Background technique [0002] With the development of the 4th Generation Mobile Communication (abbreviation: 4G) technology, many users have begun to use the 4G network for communication, such as Circuit Switched Fallback (CSFB), Global Mobile Communication System (Global System for Mobilecommunication, referred to as GSM) and long-term evolution (Long Term Evolution, referred to as: LTE) synchronous support (Simultaneous GSM and LTE, referred to as: SGLTE), voice and LTE simultaneous support (Simultaneous Voiceand LTE, referred to as: SVLTE) and A voice service is performed based on technologies such as voice over LTE (Voice over LTE, VoLTE for short). [0003] Among them, CSFB refers to a technology in which a terminal falls back from a 4G network to a 2G or 3...
