Problems solved by technology

[0002] In the 4G era, most dual-card terminals are dual-card dual-standby single-pass terminals, and the radio frequency channel is single transmission and single reception or single transmission and double reception. The card can only be offline (the other card of a terminal that supports dual reception can receive signals, but cannot send signals), and the services of the two SIM cards cannot be activated at the same time
[0003] Some single-transmission and dual-reception terminals realize the so-called dual-card dual-communication through time-division multiplexing between the two SIM cards through the transmission path when both SIM cards are in the service state. However, the implementation process of this solution is complicated, and sharing the transmission path will lead to The service performance of the two SIM cards is affected, especially when one SIM card is in the voice service state and the other SIM card is in the data service state, voice service packet loss and delay increase will seriously affect the service experience
It can be seen that the implementation of dual-card dual-pass on 4G terminals is mainly limited by the transmission channel.

Abstract

The invention provides a method, system and device for establishing communication connection and a computer readable storage medium, and relates to the technical field of communication. The method for establishing the communication connection comprises the following steps: the terminal establishes a main communication connection of a main SIM card with a main base station corresponding to the main SIM card, wherein the main communication connection occupies a radio frequency transceiving path of a first radio frequency transceiving chip of the terminal; the terminal establishes an auxiliary communication connection of the main SIM card with an auxiliary base station corresponding to the main SIM card, wherein the auxiliary communication connection occupies a radio frequency transmit-receive path of a second radio frequency transmit-receive chip of the terminal; the terminal receives a service request sent by a base station corresponding to the auxiliary SIM card; the terminal disconnects the auxiliary communication connection with an auxiliary base station corresponding to the main SIM card; and the terminal establishes communication connection of the auxiliary SIM card with a base station corresponding to the auxiliary SIM card, wherein the communication connection occupies a radio frequency transceiving channel of a second radio frequency transceiving chip of the terminal. According to the invention, the dual-card dual-pass of the terminal is realized, the main SIM card and the auxiliary SIM card of the terminal occupy different radio frequency transmit-receive paths during service concurrence, and the service performance of the main SIM card and the auxiliary SIM card is ensured at the same time.
