Abstract

The invention relates to a multi-card multi-standby mobile terminal as well as a user identification card switching method and a user identification card switching device thereof. The switching method comprises the following steps: monitoring the signal strength of virtual user identification cards and physical user identification cards; when receiving an instruction that a user manually selects a network, controlling the multi-card multi-standby mobile terminal to stay in the network manually selected by the user, and starting a user identification card corresponding to the network manually selected by the user; and, when receiving an instruction that the user automatically selects a network, starting the corresponding virtual user identification cards or physical user identification cards according to the signal strength of the virtual user identification cards and the physical user identification cards. By virtue of the switching method, a mobile network can be flexibly and conveniently selected by virtue of the multi-card multi-standby mobile terminal when a multi-card multi-standby function is realized by virtue of the virtual user identification cards.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-card multi-standby mobile terminal and a user identification card switching method and device thereof. Background technique [0002] With the successive commercialization of various mobile network protocols, it has become a common phenomenon to cover multiple network signals in the same area, which has triggered fierce competition among operators operating different mobile networks and brought more choices to users. . [0003] In order to facilitate users to flexibly choose a mobile network to reside on according to their own needs, most mobile phones have a multi-card multi-standby function. [0004] The original multi-card multi-standby mobile phone reserved multiple subscriber identification card slots, and then multiple physical subscriber identification cards could be inserted into the corresponding subscriber identification card slots to realize the multi-ca...
