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.
