Abstract

The invention relates to the field of communication technologies, and discloses a mobile terminal and a call switching method for a multi-card multi-standby mobile terminal. At least two SIM cards operating at different frequency bands are inserted in the multi-card multi-standby mobile terminal, and the call switching method comprises the steps of detecting received signal strength of all SIM cards when the mobile terminal receives a call request for the first SIM card; and switching the call request for the first SIM card to the second SIM card when the received signal strength of the first SIM card is less than that of other SIM cards, wherein the second SIM card is one of the other SIM cards with received signal strength greater than that of the first SIM card. Compared with the prior art, the call switching method for the multi-card multi-standby mobile terminal allows the request for the SIM card with weak received signal strength to be switched to the SIM card with high received signal strength in real time, thereby reducing radiation to human body; in addition, the mobile terminal can set call transfer without monitoring the received signal strength of all SIM cards in real time, thereby reducing work tasks of the mobile terminal and saving power consumption of the mobile terminal.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a call switching method for a multi-card multi-standby mobile terminal and the mobile terminal. Background technique

[0002] Generally speaking, when two users make a call, a call connection needs to be established between SIM cards (Subscriber Identity Modules, subscriber identity identification cards) inserted in their respective mobile terminals. The call connection establishment process includes the calling SIM card access phase and the called SIM card access phase. The caller sends a call request, requests access to the base station control center and mobile switching center through the base station registered by the caller, until the caller accesses, and then the mobile call center, which can be the same mobile call center or a different mobile call center, through the base station In the control center, the base station registered by the called party pages the cal...
