Problems solved by technology

[0003] General dual-mode terminals are currently designed with dual card slots. Generally, each card slot specifies the type of card that can be inserted. If the user inserts the wrong card, such as inserting a CDMA UIM card into a device that only supports GSM SIM card slot, then the user will not be able to use the card correctly

Embodiment Construction

[0021] The present invention will be further described in detail in conjunction with the drawings and embodiments below.

[0022] In a general dual-mode terminal solution, there is a main control module for interacting with users. We can call it the main control module, and the other module can be called the slave module, which only completes the realization of the communication function. No direct contact with users. figure 1 The shown dual-mode terminal includes two communication modules and two card slots, wherein each card slot is connected to the two communication modules, but switches are added to the connection lines.

[0023] A kind of CDMA / GSM dual-mode terminal that the present invention proposes supports the method for multiple card combination, comprises the following steps:

[0024] Step 1: The dual-mode terminal starts the main control module first, and connects the main control module with the two card slots;

[0025] Step 2: The main control module identifies...

Abstract

The invention discloses a method of supporting multi-card combination by a double mode terminal and the double module terminal thereof. Two card grooves and a main control module, two card grooves and accessorial modules of the double mode terminal are connected with each other through switches. The method comprises following steps: (a) firstly, the double mode terminal starts the main control module, then tconnects the main control module with two card grooves; (b) the main control module allocates cards for the main control module and accessorial modules according to the types of cards; (d)the double mode terminal closes the card groove switches of cards which are used by the main control module and the accessorial modules respectively according to the allocation of two cards, and closes the switches of two cards and card grooves of cards which are not used. The method does not limit the corresponding relation of the card groove and the card, supports any card combination modes, which is convenient to use of users.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for a dual-mode terminal capable of supporting multiple card combinations and the dual-mode terminal. Background technique [0002] Current users mainly use mobile phones based on GSM or CDMA networks. For a long time, GSM mobile phones and CDMA mobile phones are in a "hostile" state. Using a GSM mobile phone will not be able to enjoy the green and environment-friendly CDMA network, and a CDMA mobile phone will not be able to use an ordinary SIM card. The emergence of CDMA / GSM dual-mode terminals has completely solved this problem, allowing users to freely switch between GSM and CDMA networks, killing two birds with one stone. [0003] General dual-mode terminals are currently designed with dual card slots. Generally, each card slot specifies the type of card that can be inserted. If the user inserts the wrong card, such as inserting a CDMA UIM card into a device th...
