Abstract

The invention discloses a cell fallback method and terminal equipment, and aims to reduce the call establishment time to improve the user experience, and the method comprises the steps that the terminal equipment obtains first configuration information; the terminal equipment measures frequency point information according to the first configuration information and generates a first measurement report; the terminal device selects N fallback cells with the strongest signal strength in a first measurement report to form a first alternative cell set, wherein N is a positive integer; and the terminal equipment falls back to the corresponding fall-back cell according to the frequency point information of each fall-back cell in the first alternative cell set. Advanced measurement of the fallbackcell can be realized, the paging duration is reduced, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a cell fallback method and a terminal device. Background technique [0002] At present, in the implementation process of CSFB (Circuit Switched Fallback, circuit domain fallback), when the mobile terminal has an incoming call, the call session control device of the calling party sends a query request to the HLR (Home Location Register, Home Location Register) according to the called number , the home location register HLR feeds back the location information of the MSC (mobile switching center, mobile switching center), the call session control device sends a call request to the mobile switching center MSC, and the mobile switching center MSC sends a call request to the MME (Mobile Management Entity, mobile management entity) according to the SGs interface Send a paging request, the mobile management entity MME sends a paging request to the mobile terminal, the mo...
