Embodiment Construction

[0018] The embodiment of the present invention proposes a method for determining the main card in a dual-card dual-standby mobile terminal, which is applied to figure 1 The mobile terminal shown, figure 1 It is a schematic diagram of an application scenario for determining a main card method in a dual-card dual-standby mobile terminal according to an embodiment of the present invention, including: a radio interface layer (RIL, Radio Interface Layer) module 101, a card-one protocol stack module 102, a card slot one 103, and a card two Protocol stack module 104, card slot 2 105. Among them, the RIL module 101 is connected with the card one protocol stack module 102 and the card two protocol stack module 104 respectively, the card one protocol stack module 102 is connected with the card slot one 103 , and the card two protocol stack module 104 is connected with the card slot two 105 . The SIM / UIM card inserted into card slot one 103 is called card one, and the SIM / UIM card inser...

Abstract

The invention provides a method and system for confirming the main card in a dual card dual standby mobile terminal. The method comprises: a card one protocol stack module reports the state information of the card one to a radio interface layer (RIL); a card two protocol stack module reports state information of the card two; RIL module confirms the main card according to the state information of the card one and state information of the card two; the specific method comprises: RIL module judges whether there is only card one inserting slot or card two inserting slot; if yes, confirming the card inserted n the slot as the main card; if no, while the card one and card two are both inserted in the slot, judging whether the card one and card two are both arranged with personal identification number (PIN), or both not arranged with the PIN protection; if yes, confirming the predetermined setting default card as the main card; if no, confirming the card without the PIN protection as the main card. The method and system provided by the invention can confirm the main card in a dual card dual standby mobile terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a system for determining a master card in a dual-card dual-standby mobile terminal. Background technique [0002] At present, the demand for dual-card dual-standby mobile terminals is increasing. An advantage of dual-card dual-standby mobile terminals over single-card mobile terminals is that they can support two protocol stacks at the same time, and users can use two different terminals. Number. [0003] Microsoft mobile (Windows Mobile) operating platform is currently a mainstream mobile operating platform, but it does not support two wireless interfaces, and all upper-layer applications are designed based on the architecture of a single card, which gives dual-card The application of dual standby mobile terminals brings certain difficulties. For example, when a user initiates an upper-layer application, the current implementation is that when the user specifie...
