Problems solved by technology

[0005] visible, figure 1 In the shown prior art, the connection between the CDMA communication module and the GSM communication module and the card slot is fixed in the hardware design, thereby limiting the arbitrariness of the user's card insertion, that is to say, the card in the card slot cannot be placed arbitrarily, must Corresponding to the communication module, in this way, there will be a problem: if the card in the card slot does not correspond to the communication module, such as placing a SIM card in the card slot corresponding to the CDMA communication module, it will cause the dual card slot mobile phone to be unable to select Network, which in turn causes the dual card slot mobile phone to fail to work according to the user's expectations, affecting the user's use

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0045] A mobile phone with dual card slots is a mobile phone with dual card slots, which can simultaneously insert two cards of different numbers into the dual card slots. The user can freely dial and answer calls on the activated cards in the mobile phone with dual card slots, and send and receive short messages. Among them, if the two card slots in the dual-card slot mobile phone can support the insertion of two different network cards, it is called a dual-network or dual-mode mobile phone, and if the two card slots support cards inserted into the same network, it is called a dual-card mobile phone. For example, if the two card slots in a dual-card-slot mobile phone can support the insertion of cards for the CDMA network and the GSM network at th...

Abstract

The invention discloses a connection method for a mobile phone with two card slots. A switch control unit is preset in the mobile phone with two card slots and the invention includes that a communication unit acquires the types of cards in a first card slot and a second card slot; then the present available networks are determined according to the types of the cards in the two card slots and are provided to users for choosing; according to the types of the cards in the first card slot and the second card slot acquired by the communication unit, the switch control unit controls the connection of the communication unit which the user selects and corresponds to the network with the card slot of the card which the user selects and corresponds to the network. The invention also discloses a mobile phone with two card slots. By adopting the invention, the free choice of cards for a user can be realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a connection method for a mobile phone with dual card slots and the mobile phone with dual card slots. Background technique [0002] There are many modes of mobile communication at present, and each mode has a corresponding mobile phone that can be used within the coverage of the communication system. For example, Global System for Mobile Communication (GSM: Global System for Mobile communication) mobile phone, Code Division Multiple Access (CDMA: Code Division Multiple Access), mobile phone, WCDMA mobile phone, etc. In the mobile phone with separated machine and card, a single-standard mobile phone has only one card slot and can only support one corresponding card. For example, a CDMA mobile phone supports a User Identity Module (RUIM: User Identity Model) card, and a GSM mobile phone supports a Subscriber Identification (SIM: User Identity Model) card. Subscriber ...
