Description
Technical field
The present invention particularly, in moving communicating field, selects the technology of communication band and pattern automatically about wireless communication field.
Background technology
For a radio communication device, for example (Personal DigitalAssistant PDA), intelligent mobile phone mobile communications devices such as (smart phone), usually must emphasize the stand-by time and the air time of its product for mobile phone, personal digital assistant.This be because mobile communications device for easy to carry and when volume dwindled as far as possible, but also remote-effects the battery occupation space.Therefore in battery limited under the situation in space, except the development novel battery, it is also very important how to reduce electrical source consumption.
With reference to figure 1 with the explanation known technology.Fig. 1 is the calcspar design of a known communicator 100, comprise an antenna 102, a radio frequency (Radio Frequency, RF) transceiver (transceiver) 104, a simulation fundamental frequency processor 106, an application processor 108, a memory 110 and an input/output interface 112.With a global system for mobile communications (Global System for Mobile Communications, GSM) mobile phone 100 is an example, when the user presses the mains switch on the input/output interface 112 and after making mobile phone 100 start, application processor 108 can produce a log-on message, it is successively by simulation fundamental frequency modulator 106, transceiver 104, reach antenna 102 and be sent to contiguous base station (Base Station), do the operation of position login with Request System.Log-on message is subsequently via base station controller (Ba seStation Controller, BSC), be transferred to visitor's position recorder (Visitor LocationRegister again, VLR), just can have the information of mobile phone 100 present positions afterwards in the communications network system, mobile phone 100 also just has call function.
For multiband multimode (multi-band, multi-mode) radio communication device, the mobile phone such as double frequency, three frequencies, four frequencies of for example bragging about international roaming (roaming) convenience now on the market, when start, can scan exercisable frequency band of communicator and pattern earlier, finding a spendable service network, and to this service network registration.With reference to the illustrative examples of figure 2, the course of work when Fig. 2 is a three-frequency mobile phone start.Behind the mobile phone power-on (202), search earlier first frequency band (204),, then use first frequency band to send log-on message (208),, then begin cell-phone function (212) and arrive end (232) if succeed in registration (210) if searches successfully (206).Get back to square (206) and (210), if not, then search second frequency band (214),, then use second frequency band to send log-on message (218),, then begin cell-phone function (212) and arrive end (232) if succeed in registration (220) if searches successfully (216).Get back to square (216) and (220), if not, then search the 3rd frequency band (224),, then use second frequency band to send log-on message (228),, then begin cell-phone function (212) and arrive end (232) if succeed in registration (230) if searches successfully (226).Get back to square (206) and (210), if not, then judge no spendable service network (222) and to end (232).By above flow process as can be known, when communicator scans spendable service network, will that is to say that this search process may be dialed the more power consumption of taking on the telephone than connecting service network than consuming more power supply in the general operation.
In addition, and though set communication regional service band and pattern by user oneself, the scanning process of avoiding, but the shortcoming person of being to use must know this communicate by letter regional spendable frequency band and pattern in advance.For example gsm system mostly uses 900MHz and 1800MHz in Europe, then uses 850MHz and 1900MHz in the North America.WCDMA system for example again, in Europe and Pan Asia use 2100MHz, then use 850MHz and 1900MHz in the North America, will use 1700MHz in Japan in the future.Want user's these complicated system specifications of being familiar with, will become unfriendly in the operation.
Therefore, be necessary to provide a kind of and do not need scan band and pattern, and automatically help the user to select the device and method of frequency band and pattern.
Summary of the invention
An aspect of of the present present invention is to provide a kind of radio communication device, comprises: (Global Positioning System, GPS) module are used to obtain the position of radio communication device to a global positioning system; One storage module includes and has stored a plurality of communications area, and each area is a frequency band of correspondence and a database of a pattern; One processing module is connected with GPS module and storage module; And a mobile communication module, be connected with processing module; Wherein, this processing module utilizes this position and this database selecting this frequency band and this pattern, and this mobile communication module uses this frequency band and this pattern and sends a log-on message.
Another aspect of the present invention is to provide a kind of control method of radio communication device, wherein radio communication device is supported a global positioning system and a built-in database, and the method includes the steps of: the position of (a) obtaining radio communication device by global positioning system; (b) Query Database is come in the position obtained of utilization, to select an employed frequency band in this position and a pattern; And the frequency band of (c) use selecting and pattern and send a log-on message of radio communication device.
