According to the present invention, the WCDMA baseband processor communicates by serial ports and PHS communication module, and the mode of ordering by AT realizes the software control function.For the WCDMA part, mainly in the WCDMA baseband processor, handle.
Operation to multimode mobile communication terminal of the present invention describes below.
The operating state of mobile phone can be divided into idle condition and service connected state, respectively control procedure of the present invention is described below.
Idle condition mainly comprises two sub-states: the start-up logging process, be in holding state after succeeding in registration.
Selection for different districts in the selection of mainly carrying out heterogeneous networks under the multi mode terminal idle condition and the consolidated network.Selection for different districts in the consolidated network (as the WCDMA network), all realize at standard agreement and device and functional module, do not pay close attention in the present invention, this programme is mainly realized how controlling and is selected different networks, and the priority level that heterogeneous networks is selected is higher than the priority level that different districts is selected in the consolidated network.
In the network selection process, three kinds of patterns are arranged: manual preference pattern, priority preference pattern, automatic preference pattern.These three kinds of patterns, the user can select in the interface menu by multi mode terminal.
Fig. 3 shows the process chart of manual preference pattern.
Manual preference pattern and traditional nonstandard multi mode terminal are realized similar, receive the handset-selected mode command of user's selection when multi mode terminal after, (as the WCDMA network) carries out registration process in the network that the user selects, the single mode mobile phone implementation procedure of this process and standard is the same, after succeeding in registration, just enter into the holding state of idle pulley, service call is initiated or received to latency services.Behind registration failure, then this network selecting failure, and be prompted to the user, wait for other operations of user.
The invention is characterized in priority preference pattern and automatic preference pattern.In these two kinds of patterns, the first pattern communication module and the second pattern communication module (being WCDMA radio frequency unit and PHS communication module) are to controller (WCDMA baseband processor) reporting ent state, controller is automatically selected current communication pattern according to the network state of the first pattern communication module and the report of the second pattern communication module according to predefined order.
Fig. 4 shows the handling process of priority preference pattern.
When the user selects the priority preference pattern, the user at first sets priority orders by mobile phone interface on multi mode terminal, be higher than the WCDMA network as the PHS network priority, after then multi mode terminal receives the web search order, earlier carry out registration process in the PHS network successively, the single mode mobile phone implementation procedure of this process and standard is the same, after succeeding in registration, just enter into the holding state of idle pulley, service call is initiated or received to latency services.Behind registration failure, then select the WCDMA network to carry out registration process again, the single mode mobile phone implementation procedure of this process and standard is the same, after succeeding in registration, just enters into the holding state of idle pulley, and service call is initiated or received to latency services.After registration in the WCDMA network also failure, it is unsuccessful then to point out user network to select.
Fig. 5 shows the handling process of automatic preference pattern.
After the user selects automatic preference pattern, multi mode terminal is at first by comparing heterogeneous networks signal strength signal intensity size, at first select the strongest network of signal to register, single mode mobile phone implementation procedure for registration process in the peak signal network and standard is the same, after succeeding in registration, just enter into the holding state of idle pulley, service call is initiated or received to latency services.Behind registration failure, then select time strong network signal to register; And the like, up to the network that finds can succeed in registration.If it is unsuccessful that all-network is all registered, point out then that the user is current not to have the network that can serve.In this programme, reporting mainly of WCDMA network signal just possesses in the WCDMA baseband processor; For the signal of PHS network, mainly pass through AT command mode enquiring PHS communication module by the WCDMA baseband processor, by the PHS communication module PHS network signal that measures is reported the WCDMA baseband processor by the mode that AT orders; In the CPU core in the WCDMA baseband processor, the size of two kinds of signals is compared, select the strongest network of signal as registered network.
After user registration success, just enter idle holding state; At idle holding state, because the user moves, the possibility of existence from a netsurfing to another network, the present invention has realized the automatic roaming handoff functionality according to following processing mode: after multi mode terminal succeeds in registration, the network that selection is succeeded in registration enters idle holding state, the mode of CPU in the WCDMA baseband processor by AT order inquiry obtain constantly that the PHS module measures around PHS network signal situation, the WCDMA network signal intensity that PHS network signal intensity that the PHS communication module is measured and WCDMA baseband processor report self compares.If the current network that succeeds in registration is the WCDMA network, when the PHS network signal that measures under the idle holding state is better than the WCDMA network signal intensity, then can carry out network selecting again, to select the PHS network as registered network by the mode of the automatic preference pattern of network; The PHS network signal that measures under idle holding state is weaker than the WCDMA network signal, then continue to keep current resident constant to the WCDMA network, the PHS network signal intensity that continuation measures by AT enquiring PHS communication module, and and the WCDMA network signal intensity that reports of WCDMA baseband processor compare, whether need to carry out again network selection procedures with decision.
Under the service communication state, the typical case is under talking state, processing procedure of the present invention is as follows: the CPU of WCDMA baseband processor obtains the PHS network signal intensity by the AT order in the multi mode terminal in communication process, and collects the WCDMA network signal intensity that WCDMA baseband processor self reports.When the PHS network signal intensity is higher than certain threshold value (this threshold value can set in advance or dynamically adjust according to the ambient signal situation), CPU in the baseband processor starts the PHS communication module by the AT control mode and sets up the communication link process, after communication link is set up, if the signal of all sub-districts of WCDMA network is lower than a certain threshold value (this threshold value can set in advance or dynamically adjust according to the ambient signal situation), then speech is switched on the communication link that PHS set up, to realize automatic switching function.
By above explanation as seen, implementation simple and flexible of the present invention can utilize ripe single mode device and module to realize non-standard multimode terminal fast.
And, by real-time monitoring, according to the size of heterogeneous networks signal strength signal intensity to the ambient network signal, whether decision carries out network selecting again, realized automatic roaming and handoff functionality, can select the network of suitable network flexibly according to user's demand simultaneously as current service.
In addition, it should be noted that above explanation only is exemplary, is not construed as limiting the invention.
For example, being embodied as example with the WCDMA/PHS multi mode terminal above describes the present invention.But the present invention is not limited to the WCDMA/PHS multi mode terminal, but can be applied to other multimode combination, for example GSM/PHS multi mode terminal, CDMA2000/PHS multi mode terminal or the like.
The present invention also is not limited to dual-mode handset, but can be applied to support the mobile phone of two or more communication patterns, for example, and three mould mobile phones or four mould mobile phones.
