Abstract
The invention provides a calling-control method of double-frequency double-mode terminal. The DBDM terminal has WCDMA and CDMA modem. The method comprises: requiring for calling control to the Subsciber Identity Module SIM connecting to the WCDMA modem when processing calling; operating the Subsciber Identity Module SIM calling-control function by the WCDMA modem in the CDMA modem when the calling is CDMA calling and operating the Subsciber Identity Module SIM calling-control function in the WCDMA modem when the calling is WCDMA calling. The invention is able to apply USIM calling-control function in the CDMA modem and connects more than 3 processors in a DPRAM.
Description
Technical field
The present invention relates to the calling-control method of a kind of DBDM (DBDM:Dual Band Dual Mode) terminal, be particularly related in the DBDM terminal of using WCDMA and cdma modem (MODEM), when in the CDMA field, calling out, utilize the calling-control method of the DBDM terminal of subscriber identification module (the SIM:subscriber identification module) controlling call that is connected with the WCDMA modulator-demodulator.
Background technology
In existing DBDM (the DBDM:Dual Band Dual Mode) terminal, WCDMA and CDMA coexist.User interface (UI:User Interface) is on the WCDMA modulator-demodulator, and cdma modem is only done the modulator-demodulator use.User interface UI is to use the UI on the WCDMA.
But it is possible utilizing the calling control (Call Control) of universal subscriber identity module USIM (UniversalSubscriber Identity Module) among the WCDMA of existing DBDM terminal, the controlling call but CDMA has no idea.
That is because USIM is connected with the WCDMA modulator-demodulator, be possible when using the WCDMA modulator-demodulator, so utilize the calling control of USIM.But, when using cdma modem, because can not use the USIM that is connected with the WCDMA modulator-demodulator, so can not use CCF.
And, existing DBDM terminal not only can not be used CCF in CDMA pattern (MODE), but also can only use the problem of 2 processors (Processor) among the dual-port random access memory DPRAM (Dual PortRAM) who exists terminal to have.
Summary of the invention
The object of the present invention is to provide a kind of calling-control method of DBDM terminal, the user interface of terminal (interface) is placed on the WCDMA modulator-demodulator, and the USIM that is connected with the WCDMA modulator-demodulator by the utilization of WCDMA modulator-demodulator when calling out in the CDMA field uses CCF, therefore also can use the USIM CCF in cdma modem; And utilized the DBDM terminal call control method that in a dual-port random access memory (DPRAM), can connect the subscriber identification module SIM that uses the processor (PROCESSOR) more than 3.
In order to achieve the above object, the invention provides a kind of calling-control method of DBDM terminal, this DBDM terminal possesses WCDMA and cdma modem, and this method comprises:
In the time will calling out, to the step of the subscriber identification module SIM request call control that is connected with the WCDMA modulator-demodulator;
When described calling is the CDMA calling, in cdma modem, carry out described subscriber identification module SIM CCF by the WCDMA modulator-demodulator, when described calling is the WCDMA calling, in the WCDMA modulator-demodulator, carry out the step of described subscriber identification module SIM CCF.
Beneficial effect of the present invention is, end user interface is placed on the WCDMA modulator-demodulator, pass through the WCDMA modulator-demodulator when in the CDMA field, calling out, utilize the USIM that is connected with the WCDMA modulator-demodulator to use CCF, so on cdma modem, also can use the USIM CCF, and on a DPRAM, can connect 3 above processors uses.

Embodiment
Followingly describe the embodiment of calling-control method that have an as above feature of the present invention utilizes the DBDM terminal of subscriber identification module in detail with reference to accompanying drawing.Fig. 1 is a DBDM terminal structure block diagram of the present invention.As shown in the figure, by the WCDMA modulator-demodulator 1 that comprises user interface (UI) and be connected with USIM2, cdma modem 5, in order to carry out the DPRAM4 of communication between WCDMA modulator-demodulator 1 and the cdma modem 5, be connected and show display window 3 formations of the data of importing from the outside with WCDMA modulator-demodulator 1.
Above-mentioned Fig. 1 also as can be known, because the present invention is combined into a user interface UI to CDMA UI and WCDMA UI on WCDMA modulator-demodulator 1, so in the CDMA field, use in the cdma modem 5, communicate by letter with WCDMA modulator-demodulator 1 by DPRAM4, use the user interface UI on the WCDMA modulator-demodulator 1, and can use CCF as the characteristic of the USIM2 that is connected with WCDMA modulator-demodulator 1.Existing WCDMA UI and CDMA UI are inconsistent, but the present invention is because WCDMA UI is consistent with CDMA UI, so can use regardless of what communication mode by a user interface UI.Convenience is provided therefore for terminal manufacturer's user interface UI designer.
And, because communication by (between WCDMA modulator-demodulator and the cdma modem) between the processor that utilizes DPRAM4, can on cdma modem 5, use the method for the same UI of WCDMA modulator-demodulator 1 to carry out CDMA calling and WCDNA calling, on a DPRAM, can connect the advantage that 3 above processors use so possess.
Fig. 2 is the flow chart of an embodiment of the DBDM terminal call control method of utilizing subscriber identification module SIM of the present invention.As shown in the figure, in the time will calling out, comprising: to the step of USIM2 request call control by the user interface UI of WCDMA modulator-demodulator 1; When above-mentioned calling is the CDMA calling, in cdma modem 5, carry out above-mentioned USIM2 CCF by WCDMA modulator-demodulator 1, when above-mentioned calling is the WCDMA calling, in WCDMA modulator-demodulator 1, carry out the step of above-mentioned USIM2 CCF.
Here, when will carry out above-mentioned calling, the KOC kind of call is by the communication mode decision of the mobile communication base station that is connected with the DBDM terminal.That is, when the communication mode of the base station that is connected with terminal is the CDMA mode, carry out calling control when will call out, when ways of connecting is the WCDMA mode, carry out calling control by WCDMA modulator-demodulator 1 by cdma modem 5.
The action of the present invention that is made of above-mentioned steps describes as follows.
At first, the user is in order to carry out call function by the user interface UI call try on the WCDMA modulator-demodulator 1.When above-mentioned calling is attempted, to the CCF of the USIM2 request that is connected with WCDMA modulator-demodulator 1 as the characteristic of USIM2.
After above-mentioned USIM2 request call controlled function, judge the communication mode that is using in terminal.That is, judge that terminal is according to work of cdma communication mode or the work of WCDMA communication mode.
When above-mentioned judged result, terminal are worked in the cdma communication mode, carry out the CCF of USIM2 by cdma modem 5.Otherwise, when promptly terminal is worked with the WCDMA communication mode, carry out the CCF of USIM2 by WCDMA modulator-demodulator 1.
By this method, in cdma modem, also can use CCF as the USIM characteristic.
That is, possesses the advantage of in cdma modem, carrying out the USIM CCF that is connected with the WCDMA modulator-demodulator by above-mentioned WCDMA modulator-demodulator.
The foregoing description only is used to illustrate the present invention, and is not to be used to limit the present invention.
