Description
Technical field
The present invention relates to the communications field, particularly the dual-mode terminal technology in the communications field.
Background technology
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 Multiple Access, be called for short " TD-SCDMA "), micro-wave access to global intercommunication (Worldwide Interoperability for Microwave Access, be called for short " WiMAX "), Long Term Evolution (Long Term Evolution, be 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 mobile terminal the technical scheme of multiple wireless system can be 11136547 United States Patent (USP) referring to the patent No..
The GSM/TD-SCDMA dual-mode terminal can be further divided into single-pass dual-mode terminal and bilateral dual-mode terminal.The single-pass dual-mode terminal refers to that synchronization can only carry out resident and initiate communication traffic by a Serving cell under a kind of mobile network's pattern (access technology).Especially when a plurality of circuit switching (Circuit Switching is called for short " CS ") occurring, be also like this in the time of packet switching (Packet Switching is called for short " PS ") service concurrence.2G in the market (second generation mobile communication system), 3G (3-G (Generation Three mobile communication system)) mobile terminal all belongs to this form basically.The single-pass dual-mode terminal refers to have the terminal of two cover radio frequencies and antenna assembly, by two cover radio frequency and antenna assemblies, accesses respectively GSM and TD-SCDMA.At present, the single-pass dual-mode terminal also is in the research and development stage, and its implementation does not have unified standard yet.
