Abstract

The invention discloses a dual-card UE data transmission method and device, a storage medium and user equipment. The dual-card UE is provided with a first SIM card and a second SIM card, and the method comprises the steps: when the first SIM card is in a connected state, determining the wireless operation requirement of the second SIM card, wherein the first SIM card is connected with a first service base station; requesting at least no data transmission time slot or radio frequency resource from the first serving base station according to the wireless operation requirement; and executing thewireless operation of the second SIM card at least by utilizing the no-data-transmission time slot or the radio frequency resource. According to the technical scheme of the invention, the data transmission performance when the two SIM cards of the dual-card UE share the communication baseband can be improved.

Description

technical field

[0001] The present invention relates to the field of communication technologies, and in particular to a dual-card UE data transmission method and device, a storage medium, and user equipment. Background technique

[0002] A dual-card user equipment (User Equipment, UE) refers to a terminal device capable of using two subscriber identification cards (Subscriber Identification Module, SIM) (hereinafter referred to as SIM1 and SIM2). The two SIM cards of the dual-card UE may need to occupy the communication baseband and radio frequency at the same time. For example: when SIM1 is in the connected state, SIM2 performs wireless operations such as paging reception, system message reception, signal measurement, and cell search; further, when SIM2 paging is received, or SIM2 needs to correspond to radio resource control (Radio Resource Control, RRC ) request on demand (on demand0 system message, or when the user actively initiates SIM2 access, perform network access ...

Examples

Embodiment Construction

[0029] As mentioned in the background art, the first method will result in failure to page the UE, degrade data transmission performance, waste network radio resources, and affect network operation indicators. The second method will affect the smoothness of data transmission and reduce the efficiency of data transmission.

[0030] In the technical solution of the present invention, in the state where the first SIM card is connected to the first serving base station, by requesting the first serving base station for no data transmission time gap or radio frequency resources for performing wireless operations of the second SIM card, it is possible Execute the service of the second SIM while affecting the service of the first SIM card as little as possible; that is, through the coordination between the dual-card UE and the base station, it is possible to avoid wasting wireless resources and improve the dual-card UE The data transmission performance of a SIM card.
