Description
Technical field
The present invention relates to mobile communication field more particularly to a kind of mobile terminals and usim card dispatching method.
Background technology
There are the communication technology of multiple types in current mobile communication system, as 2G (Generation Mobile Telecommunication System technology,
2rd Generation) GSM (global system for mobile communications, Global System of Mobile
Communication), 3G（3G (Third Generation) Moblie, 3rd Generation）TD-SCDMA（TD SDMA connects
Enter, Time Division-Synchronous Code Division Multiple Access）Business etc.；And with movement
The evolution of technology, the TD-LTE based on evolution in TD-SCDMA technology（Timesharing long term evolution, Time Division Long
Term Evolution）4G（Fourth generation mobile communication technology, 4rd Generation）It gradually promotes and applies at home, base
It is also more and more perfect in the 4G business of TD-LTE.
Existing 2G and 3G network have formd all standing, and network performance meets client communication demand, TD-LTE networks
Still in the initial stage of network construction, hot spot is paid the utmost attention in network construction, and network is unable to all standing.In practical applications, one
Aspect is needed when TD-LTE occurs business and network and cannot service, it is desirable to and business can be switched to TD-SCDMA or GSM network,
On the other hand, it is also desirable to which terminal can support data service and speech business complications.Therefore multi-mode multi-standby terminal is proposed
Good interoperability requirement.
Current bimodulus single-chip to be divided into and multi-chip two schemes, there is no the handover managements of usim card to ask for the former more
There is usim card handover management in topic, the latter, use hard handover approach management at present, cannot achieve in this case double
It waits for, needs to be manually switched to the standard for needing generation business every time.
Existing TD-LTE is with TD-SCDMA multimode twin-core flake products due to the agreement regulation of no standard, TD-LTE and TD-
SCDMA is two sets of independent systems to the management of usim card, and terminal just needs manual switching usim card simultaneously when standard switches
Connecting side, there are two types of the current shared processing substantially to usim card：
One is directly use switching；It is namely similar to and uses single-pole double throw in usim card interface
Usim card is switched to the sides TD-LTE by switch when TD-LTE needs access；TD-SCDMA needs then to cut usim card when access
Change to the sides TD-SCDMA；Two kinds of standard switching times of this processing mode are very long, and cannot handle background well and sweep
It retouches.
Another processing mode is to intend a USIM in TD-LTE side forms（Referred to as pseudo- card）, by the general information of USIM
Be stored in the sides TD-LTE, the switching time of two kinds of standards can be shortened in this way, at the same can be relatively good processing TD-LTE the back of the body
Scape scans problem.But the direct-cut operation that the processing mode of this usim card is still blocked（Network bi-directional authentication needs true
Card）, also can not really accomplish TD-LTE and TD-SCDMA double standby, namely be difficult by the data service of the high speed of TD-LTE and
The speech business of TD-SCDMA perfectly combines, and especially keeps good call sum number when needing frequently authentication
According to business.
Therefore, the mobile terminal of the existing technology the problems such as time caused by direct-cut operation is long between multiple types.
