Abstract
The invention relates to the field of communication and discloses a method reading essential file information before network selection of a dual-mode terminal and the dual-mode terminal. In the method, after a non-access layer of a network system in the dual-mode terminal reads the essential file information used for network selection, the read essential file information shared by a non-access layer of a second network system of the dual-mode terminal is sent to the non-access layer of the second network system, so two non-access layers are prevented from reading two sets of the essential file information with the same contents and information sharing of shared EF is realized. Therefore, the time for booting and network searching is shortened, the frequency of accessing card hardware interfaces is simultaneously reduced and the equipment stability is enhanced.
Description
Technical field
The present invention relates to the communications field, particularly the dual-mode terminal technology in the communications field.
Background technology
Continuous development along with the communication technology, various types of wireless communication systems have appearred, as global system for mobile communications (Global System for Mobile communication, be called for short " GSM "), Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA "), TD SDMA (Time Division Synchronous Code Division MultipleAccess, be called for short " TD-SCDMA "), micro-wave access to global intercommunication (WorldwideInteroperability for Microwave Access, be called for short " WiMAX "), Long Term Evolution (LongTerm Evolution is called for short " LTE ") etc.
At present, many terminals (as mobile phone) all can be supported two kinds of wireless systems (or wireless standard), as not only supporting GSM but also support TD-SCDMA.The terminal of two kinds of wireless systems of this support is commonly referred to dual-mode terminal.Support that about portable terminal the technical scheme of multiple wireless system can be 11136547 United States Patent (USP) referring to the patent No..
Existing dual-mode terminal needs to carry out subscriber identification module (Subscriber IdentityModule after start, be called for short " SIM ") or the user serve identification module (User Service Identify Module, abbreviation " USIM ") initialization, and after the SIM/USIM card initialization is finished, before preparing network selection, can from card, read the relevant constituent instruments of network selection (Elementary File is called for short " EF ") content earlier, as EF
