2. terminal need be supported this flow process (terminal of existing network is not all supported, needs customization yet)
3. if this process occurs in the business initializtion stage, just increased access delay, influence user's impression.
4. if the user carries out the voice-and-data business simultaneously, existing terminal is not supported this demand.
For scheme two, also there is following problem:
1. consider the QOS of data service, cover under incomplete situation,, cause the increase of the cutting off rate of speech business because success rate for switching is not very desirable between system at WCDMA.Have a strong impact on operator's brand image.
2. if the user carries out the voice-and-data business simultaneously, existing terminal is not supported this demand.

Embodiment
Below the specific embodiment of the present invention is described in detail.
In the prior art, the dual-mode terminal of standard can not work in (for example while transmitting/receiving signal in gsm system and WCDMA system) in two kinds of patterns simultaneously.Particularly, the dual-mode terminal of standard can not realize that circuit domain works among a kind of pattern, and data field is operated among the another kind of pattern.
In bimodule mobile communication terminal of the present invention, have independent circuit domain part and data field part, the partly shared same IMSI of circuit domain part and data field wherein, and can the while according to different wireless access ways transmitting/receiving signal respectively.Thereby the user can carry out Speech Communication and data communication easily simultaneously.
Need to prove that at this present invention can be applied to the combination of various communication modes, include but not limited to GSM, WCDMA, CDMA2000 and TD-SCDMA etc.But, be that example describes one embodiment of the present of invention with GSM and WCDMA below for the convenience of narration.
Mobile communication terminal comprises two major parts according to an embodiment of the invention:
Circuit domain part: comprise GSM base band and radio-frequency unit, support the GSM function, do not support the GPRS function;
Data field part: comprise WCDMA base band and radio-frequency unit.Baseband part is not supported WCDMACS (circuit domain) function, supports WCDMA PS (data field)+GPRS function.Radio-frequency unit supports the emission of WCDMA system and gsm system signal to receive.When working in GPRS pattern following time, can share the radio-frequency unit of circuit domain part.
Owing to be designed to by GSM voice-over business, and,, closed the WCDMA circuit domain function simultaneously so circuit domain need be supported the GSM access technology by the WCDMA bearing data service.Simultaneously, in order to carry out data service in the area that does not have WCDMA to cover, data field is supported WCDMA and two kinds of access technologies of GPRS, and is supported in the interoperability (cell selecting is switched) between GSM network and the WCDMA network.
Above two large divisions has same IMSI (international mobile subscriber identifier, International Mobile Subscriber Identity).And these two parts can be in operating state simultaneously, promptly can be simultaneously respectively with gsm system and WCDMA system synchronization and receive/transmit.
Simultaneously, carry out following configuration at network side:
1 by GSM and WCDMA system message broadcast cell reselection algorithm, makes that the GPRS/GSM sub-district is lower than the preferred rank in WCDMA sub-district concerning terminal.
Do not establish Gs interface between 2 2G MSC (mobile switching centre, Mobile Switching Center) and 3G SGSN (Serving GPRS Support Node, Serving GPRS Supporting Node)/2.5G SGSN, promptly network does not support co-location to upgrade.
Can as above dispose at network side at an easy rate.
Below the mobile communication terminal of present embodiment and the operation of mobile communication system are described.
At first, under the situation of mobile communication terminal when startup, circuit domain part is only searched for the GSM signal, synchronously and sign in to gsm system.On the other hand, data field part first search WCDMA signal, if judge and to have the WCDMA signal, then the data field part is synchronously and sign in to the WCDMA system.If the WCDMA signal does not exist, then data field partly signs in to gprs system.
Have again under the situation of WCDMA signal at existing GSM signal, portable terminal of the present invention can sign in in GSM and the WCDMA system simultaneously.That is, circuit domain partly remains in the gsm system, and data field partly remains in the WCDMA system.
Because part of the circuit domain in the portable terminal of the present invention and data field part are worked in gsm system and WCDMA system respectively, so this terminal can utilize circuit domain part and data field partly to carry out circuit domain business and data field business simultaneously respectively.For example: can when carrying out caller or called voice call, carry out data communication, as downloading data.
Simultaneously, because part of the circuit domain in the portable terminal of the present invention and data field part are worked in gsm system and WCDMA system simultaneously, when carrying out data communication, need not with prior art in carry out switching like that from the GSM network to the WCDMA network, perhaps when carrying out Speech Communication, carry out switching from the WCDMA network to the GSM network, thereby can immediately carry out speech or data communication, not have any additional time-delay.
On the other hand, when the user moves, if along with the moving of terminal, the WCDMA signal more and more a little less than, when the WCDMA signal level was lower than a predetermined threshold value, terminal partly switched to data field on GSM or the GPRS.Like this, even in the area that does not have the WCDMA signal, also can carry out data communication by GPRS.
In addition, under the situation that does not exist WCDMA to cover, data field partly resides on the GSM.At this moment, the data field of terminal part detects the WCDMA signal strength signal intensity at interval termly according to preset time.If the WCDMA signal level is higher than predetermined threshold value, and satisfy different system cell gravity treatment requirement, then the data field part is moved to WCDMA from GPRS immediately.
Be illustrated with the example that is applied as of the present invention in GSM/WCDMA above.The invention enables the operator that has the GSM network in the process of building the WCDMA network, under situation about need not, realize by the GSM carry voice traffic by the WCDMA bearing data service to the existing network upgrading.Have plurality of advantages in this present invention, for example can realize audio call and data call simultaneously, and when carrying out audio call or data call, can not produce the time-delay that brings because of the network switching.
More than utilize a specific embodiment to describe the present invention.But the invention is not restricted to above-mentioned specific detail.For example, the invention is not restricted to the realization of GSM/WCDMA bimodulus, but can be applied to the combination in any among GSM, CDMA, WCDMA, CDMA2000, the TS-SCDMA etc.
Scope of the present invention only is defined by the claims.Within the scope of the invention that claim limited, can carry out various details and pro forma variation to the present invention.
