Problems solved by technology

[0003] At present, mobile terminals such as mobile phones generally support multiple network standards and address-based For the voice service of the multimedia subsystem (Ip Multimedia Subsystem, IMS), when there is no card emergency communication, the emergency call based on the IMS network is preferentially selected. When the IMS network does not support no card emergency communication, other standard cells are selected to initiate the emergency call. It is easy to lead to a long call-through time and the call-through rate may be affected by complex signaling and reduce
[0004] In addition, the emergency communication function without a card is in the International Organization for Standardization (3rd Generation Partnership Project, 3GPP) protocol, which allows the operator's network not to support this function. When making an emergency call, the phone interface will briefly display "Dialing", but it will automatically hang up soon and display "Call ended", which will result in the inability to connect to the emergency service desk and reduce the success rate of calls

Abstract

The embodiment of the invention discloses a card-free emergency communication method, a terminal and a readable storage medium, and the method comprises: obtaining the parameter information of at least one cell when the terminal is in a card-free state and is started, receiving at least one piece of system information of the at least one cell, determining a candidate cell supporting card-free emergency communication according to the at least one piece of system information, selecting a target cell with the best communication capability from the candidate cells based on the parameter information of the at least one cell, and carrying out card-free emergency communication in the target cell.

Description

technical field [0001] The invention relates to the technical field of card-free emergency communication, in particular to a card-free emergency communication method, terminal and computer-readable storage medium. Background technique [0002] The emergency call function is an important function that is currently required to be supported by mobile phone products. It is used to call various emergency service desks, such as fire, police, and medical emergencies, to obtain emergency assistance in case of emergency or danger. [0003] At present, mobile terminals such as mobile phones generally support multiple network standards and address-based For the voice service of the multimedia subsystem (Ip Multimedia Subsystem, IMS), when there is no card emergency communication, the emergency call based on the IMS network is preferentially selected. When the IMS network does not support no card emergency communication, other standard cells are selected to initiate the emergency call. ...
