Abstract

The embodiment of the invention discloses a wireless module, a terminal and a storage method. The wireless module comprises a control unit and an obtaining unit, wherein the control unit stores specific information in a SIM card in another storage medium except the SIM card and also stores the changed specific information in the storage medium when the obtaining unit learns that the specific information is changed; the specific information at least contains one of temporary mobile subscriber identity, location area Identity, global cell identity and base station identity. Therefore, the embodiment of the invention uses another storage medium except the SIM card to store the specific information which was stored in the SIM card and directly updates the specific information stored in the storage medium when the specific information is changed, thus achieving the aims of reducing the number of write operations of Flash of the SIM card and prolonging the writing life of Flash, and prolonging the service life of the SIM card.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, relates to a wireless module, a terminal and a storage method. Background technique [0002] Wireless terminals such as mobile phones, vehicle radios, and wireless data terminal units (DTUs) all need to use wireless modules to access the network to complete data transmission. [0003] The above-mentioned wireless module generally includes a control unit and a transceiver unit, and the processing unit is responsible for wireless resource management, mobile management, connection and call management, and short message service. When in use, the control unit uses the user identification information stored in the SIM card (such as mobile user identification code, temporary mobile user identification code, user authentication key, etc.) and mobile information (such as user current location information) to access the network. [0004] The above-mentioned mo...
