Embodiment approach

[0039] In another exemplary embodiment, the following scenario is considered: the first SIM card supports the GSM network mode and the TD-SCDMA network mode, and the second SIM card supports the GSM network mode, TD-SCDMA and TDD-LTE network modes. The first SIM card is in the TD-SCDMA network mode, and the second SIM card is initially in the TDD-LTE network mode. When the mobile terminal, for example, enters an area without TDD-LTE network coverage, the second SIM card can change from the TDD-LTE network mode to the TD-SCDMA network mode. Thus, both the first SIM card and the second SIM card are in the TD-SCDMA network mode.

[0040] It can be understood that the above description of the exemplary embodiments is for illustration purposes only, and the scope of the present invention is not limited thereto. For example, the first SIM card and the second SIM card may respectively transform from different network modes to the same network mode.

Abstract

Various embodiments of the invention provide a cell residence method for a mobile terminal, a device and a mobile terminal. The mobile terminal at least is provided with a first subscriber identification model SIM card and a second SIM card. The method comprises determining whether the first SIM card and the second SIM card belong to the same service provider, determining whether the first SIM card and the second SIM card are at the same network mode in response to the fact that the first SIM card and the second SIM card belong to the same service provider, and enabling the first SIM card and the second SIM card to reside in the same service cell in response to the fact that the first SIM card and the second SIM card are at the same network mode. By utilizing the embodiments of the invention, the two SIM cards can share measuring results, information of a service cell and information of an adjacent cell, so scheduling and empty port receiving and transmitting actions are reduced, and power consumption is saved.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 928,735, filed January 17, 2014, the entire disclosure of which is hereby incorporated by reference. technical field [0003] Embodiments of the present invention relate to the communication field, and more particularly, to a camping method, device, and mobile terminal for a mobile terminal with multiple Subscriber Identity Module (SIM) cards. Background technique [0004] With the rapid development of wireless communication technology, smart mobile terminals play an increasingly important role in people's work and life. At the same time, people's demand for wireless services has shifted from simple voice services to online video, real-time games, and precise positioning. In order to meet people's diverse service needs, mobile terminals that can support multiple, for example, two or more SIM cards have been developed. [0005] At present...
