Problems solved by technology
[0004] When the main card of the DSDS mobile terminal is in the IDLE state because the RF resources are preempted by the secondary card, and the network side has not synchronized with the state of the DSDS mobile terminal at this time, the network side will always send paging messages carrying the URNTI identifier, causing the main Although the card has obtained the radio frequency resources, it cannot process the received paging message carrying the URNTI identifier, and there is a problem of missed calls

The present application discloses a state switching method, which includes: when the first user identification card of the mobile terminal uses radio frequency resources to communicate with network equipment, the mobile terminal detects that the radio frequency resources are preempted by the second user identification card of the mobile terminal. The mobile terminal switches the communication state of the first user identification card from the paging state to the idle state. If it is detected that the radio frequency resource is re-acquired by the first user identification card, the first user identification card is updated with a cell, and if the cell update is successful, the communication state of the first user identification card is switched from an idle state to a search call status. In the technical solution of the present application, after the first user identification card reacquires radio frequency resources, the cell update of the first user identification card is performed, so that the communication status of the first user identification card is consistent with that of the network device for the first user identification card. The communication status is consistent, and the problem of missing calls in some scenarios is optimized.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method for state switching. Background technique [0002] The paging technology may refer to the process initiated by the network side to find a specific mobile terminal and notify the mobile terminal to communicate with the network side. The network paging mobile terminal can be divided into paging the mobile terminal in the P state or paging the mobile terminal in the IDLE state. The mobile terminal in the P state includes the mobile terminal in the cell paging state (CELL_PCH) or the mobile terminal In the paging state (URA_PCH) in the user registration area. Among them, when paging the mobile terminal in the P state, the paging message sent by the network side carries the UTRAN radio network temporary identity (URNTI) of the terrestrial radio network temporary identity of the universal mobile communication system. The mobile terminal performs pagin...
