Method, device and terminal for time-division multiplexing of radio frequency resources in a terminal

Abstract

The invention discloses a method, device and terminal for time-division multiplexing of radio frequency resources in a terminal, relates to the field of wireless communication, can effectively save network resources and can eliminate the impact of terminal call drop records on network KPIs. The present invention includes: receiving the connection request of the first service sent by the network to the first SIM card; determining whether the second SIM card is conducting the second service; if it is determined that the second SIM card is conducting the second service, Sending a resource release request of the second service to the network, so that the second SIM card enters an idle state; sending a connection request for accepting the first service to the network, so that the first SIM card can perform first business. The invention is mainly used in the process of time-division multiplexing of radio frequency resources in the terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and terminal for time-division multiplexing of radio frequency resources in a terminal. Background technique [0002] At present, a terminal can support two SIM (subscriber identity module, subscriber identity module) cards at the same time. However, in order to reduce costs, usually only one radio frequency module is provided in the terminal, so the two SIM cards cannot perform services at the same time. In order to enable the two SIM cards to reside in their respective service networks at the same time, the two SIM cards may share radio frequency resources in a time-division multiplexing manner. [0003] In the prior art, the services performed by the SIM card include voice services and data services, and the priority of the voice service is usually set higher than that of the data service. During the time-division multiplexing of radio frequency ...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the above-mentioned time-division multiplexing of radio frequency resources, the inventor found that at least the following problems exist in the prior art: the network maintains the wireless link until it receives the feedback from the first SIM card, thus causing a waste of network resources

Although in the end the network thinks that the terminal has dropped calls and releases resources, its dropped call records will affect the network's KPI (key performance indicator, key performance indicator)
