Method and device for time division multiplexing of radio frequency resource in terminal, and terminal

Abstract

The invention discloses a method and a device for time division multiplexing of a radio frequency resource in a terminal, and the terminal, relates to the field of wireless communication, and can efficiently save network resources and remove influence from call drop records of the terminal to network KPI (Key Performance Indicator). The method for time division multiplexing of the radio frequency resource in the terminal comprises the steps of: receiving a connecting request of a first service sent from a network to a first SIM card; determining whether a second service of a second SIM card is in progress; if the second service of the second SIM card is determined in progress, sending a resource release request of the second service to the network to enable the second SIM card to enter into an idle state; sending a connecting request of receiving the first service to the network to enable the first SIM card to perform the first service. The method and the device for time division multiplexing of the radio frequency resource in the terminal are mainly used in a time division multiplexing process of the radio frequency resource 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 is dropped and releases resources, its dropped call records will affect the KPI (key performance indicator) of the network
