Description
Technical field
The present invention relates to the cell selecting technology in the radio communication, be meant that especially a kind of multi-module mobile terminal carries out the method for cell selecting and gravity treatment.
Background technology
Along with developing rapidly of mobile communication, and user's improving constantly to business demand, existing second generation digital mobile communication system (2G) is difficult to satisfy the demand of high-speed data service, such as: existing global system for mobile communications (GSM) or Narrowband CDMA (CDMA) communication system can only provide basic voice service and some simple information series business; For the data service of dynamic real-time, its data bandwidth can't satisfy the demand of quality of service.Though the mobile communication system of the 2.5th generation such as GPRS (GPRS) occurred, the ability of its data bandwidth does not have the raising of essence yet.And for video class business such as similar video telephone, its QoS can't be guaranteed on 2G or 2.5G.Therefore, characteristics such as 3-G (Generation Three mobile communication system) (3G) is wide with its data tape, the data service disposal ability is strong have satisfied the quality of service requirement of mass data business, and then have been able to broad development.In very long a period of time in future, second generation mobile communication system will and be deposited with 3-G (Generation Three mobile communication system), so, the zone of a lot of two kinds of overlapping coverings of communication system can appear.
In order to adapt to the development of mobile communication system, portable terminal also develops into digital terminal from traditional pseudo-terminal, but present digital terminal mobile phone such as GSM mobile handset all are the single mode mobile phones, only supports to communicate with a kind of mobile communication system; And the appearance of 3G and 3G network and 2G network and deposit, make multi mode terminal developed.So-called multi mode terminal is exactly a terminal phone of supporting two kinds of mobile communication system patterns simultaneously, and existing multi mode terminal generally comprises with the lower part: possess the transmitting-receiving processing unit of 2G terminal and transmitting-receiving processing unit, terminal casing, terminal keyboard, terminal display screen, receiver and transmitter, the battery of 3G terminal simultaneously.Wherein, the described transmitting-receiving processing unit transceiver that is exactly portable terminal.
Tradition is supported the digital mobile terminal such as the GSM mobile handset of 2G communication, because the processing protocol of GSM is simple and GSM adopts time division way communication, institute is so that GSM mobile handset power consumption when communication is lower; And in 3G, owing to adopt the cdma communication technology, and bandwidth, the power efficiency of general radio frequency is lower, and the whole communication protocol complexity of 3G, makes 3G mobile bigger on power consumption.Under identical battery capacity, 2G mobile phone communication time and stand-by time are longer than 3G mobile, have manufacturer data to show, under the identical situation of battery capacity, Speech Communication duration based on the GSM system is 17 hours, and is 2.5 hours based on the Speech Communication of WCDMA system, and difference is very big.In addition, the appearance of 3G network mainly is because 2G network service bandwidth can't satisfy the demand of data service, so the main feature of 3G network is to be embodied on the data service disposal ability; And mainly be positioned at speech and simple information series business from the 2G network, very maturation and capacity also can satisfy the demands the 2G network for speech business, speech quality is also basic to match in excellence or beauty with fixing speech, therefore, if 2G and 3G are organically combined, then can reach mutual supplement with each other's advantages, guarantee QoS and improving on the network whole volume and obtain remarkable result.
As shown in Figure 1, usually portable terminal at first will select network to register after startup self-detection, and network selection is therefrom to select a signal best according to the current signal that monitors here, if the registration failure, then network is directly to portable terminal report registration failure; If register successfully, then the optional only sub-district of portable terminal is carried out resident and is entered into idle condition, the initiation of latency services.After portable terminal enters into idle condition, regulation according to 3GPP 25.304 standard agreements, portable terminal according to the measurement control messages in the network system message on every side the sub-district that might monitor monitor carry out resident so that can in time find better sub-district.The sub-district of communication system also may be the sub-district of other communication systems of same operator under when described better sub-district can be the network registry registration.If better the sub-district is monitored to, portable terminal will activate cell re-selection mechanism, reselect more suitably the sub-district and carry out resident.
Stipulated the mechanism of a kind of sub-district gravity treatment in 3GPP 25.304 standard agreements, this mechanism mainly be according to on every side the sub-district that might monitor measure, around obtaining might monitor the signal strength signal intensity of sub-district after, screen according to the signal quality of certain threshold criterion then, determine the persistent district after an only sub-district is as cell selecting and gravity treatment each sub-district.Said process both had been applicable to the single mode portable terminal, also be applicable to multi-module mobile terminal, but for multi-module mobile terminal, need affiliated 2G network of monitoring simultaneously and following of 3G network might use the signal of sub-district, therefore, there is following defective in the existing method of sub-district of selecting for multi-module mobile terminal:
1) multi-module mobile terminal under the prior art is under idle condition, need to around all sub-districts that can monitor carry out signal measurement, so, in the place that 2G network and 3G network cover simultaneously, just need measure the some sub-districts under two kinds of communication patterns, so, make the 2G receiver of multi-module mobile terminal and 3G receiver all in running order.Even adopt the sleep operation mode of saving energy, this multi-module mobile terminal is also periodically in running order; And, can not close 2G receiver and 3G receiver in the multi-module mobile terminal under the sleep pattern fully, make the power consumption of multi-module mobile terminal under idle condition strengthen like this.
2) under the zone of 2G network and the overlapping covering of 3G network, because multi-module mobile terminal can select optimum subdistrict as persistent district in 2G and all sub-districts that can monitor of 3G network, this just makes multi-module mobile terminal that the possibility and the increased frequency of sub-district gravity treatment take place under idle condition.Especially when 2G cell and 3G sub-district are at utmost not overlapping, because what the fluctuation of wireless signal and user were possible moves, multi-module mobile terminal may frequently be reselected with resident between 2G cell and 3G sub-district back and forth, the instability that causes the multi-module mobile terminal Radio Link, a lot of unnecessary network interactions also can take place simultaneously, the waste Internet resources.
3) in the existing standard agreement regulation, do not take into full account 2G network and 3G network characteristics, according to the concrete condition of multi-module mobile terminal, possibility is preferential resident in 2G cell or 3G sub-district, can only self control the optimum combination that realizes that Network provides by the multi-module mobile terminal side so.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of multi-module mobile terminal to carry out the method for cell selecting, not only reduce multi-module mobile terminal to greatest extent and select the used power consumption in sub-district, reduce waste of network resources, and separately advantage when giving full play to the 2G network and combining with 3G network.

Description of drawings
Fig. 1 is the schematic flow sheet of connection of mobile terminal into network;
The schematic flow sheet that Fig. 2 realizes for the inventive method.
Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Core concept of the present invention is: in cell selecting and reuse adoption process, support the preferential resident sub-district of portable terminal of various modes to preference pattern, such as the GSM sub-district, and, as long as the signal quality of sub-district satisfies communicating requirement under the current selected pattern, just do not consider to monitor the signal of sub-district under other pattern.Concrete implementation method is: adopt the mode that the various modes transceiver cuts out and starts in the control multi-module mobile terminal, substitute existing to following mode that all monitor the sub-district that might adopt of different mode.That is to say,, just, only between the different districts under the current selected pattern, carry out gravity treatment the transceiver Close All of other pattern in the current multi-module mobile terminal as long as cell signal satisfies communicating requirement under the current selected pattern; Only under the situation that the signal quality of sub-district under the current selected pattern all can not meet the demands, just open the transceiver of different mode one by one, carry out the gravity treatment of sub-district under the different mode by the priority preset order.Wherein, whether signal quality satisfies communicating requirement, is to compare acquisition by signal quality and the predefined signal quality threshold value that will monitor.The priority orders of different mode can be determined according to user's needs or according to the fine or not degree of network signal quality.
Give an example, for the mode mobile terminal of supporting GSM pattern and WCDMA pattern, closing and opening, the GSM sub-district of in the alternative prior art all energy measurements being arrived and the assessment of WCDMA cell signal quality by GSM pattern transceiver and WCDMA pattern transceiver in the control mode mobile terminal.Simultaneously, if expectation preferentially resides in the GSM sub-district, then can improve the resident possibility in GSM sub-district by the method for setting the unlike signal quality threshold, in other words be exactly, to the quality evaluation of WCDMA cell signal the time, improve the WCDMA sub-district can become persistent district in cell selecting and reuse adoption process signal quality threshold value, so, just can realize making the preferential resident purpose of mode mobile terminal to the GSM sub-district.
The present invention proposes at 3G network and 2G network's coverage area and the situation of depositing, and below with the gsm system in the 2G network and the WCDMA system in the 3G network and save as example, specifies the scheme of mode mobile terminal realization cell selecting and gravity treatment.In the present embodiment,, be the preferred residing mode of mode mobile terminal so select gsm system because gsm system speech processes ability is strong and power consumption is lower.
As shown in Figure 1, mode mobile terminal can be finished power-on self-test, network selecting and network registry, after succeeding in registration successively after start, this mode mobile terminal can select a proper cell as persistent district, enters the idle condition Waiting for Call then and inserts.So, when after mode mobile terminal succeeds in registration, carrying out cell selecting, under the situation that does not adopt priority control, can there be two kinds of selections: a) select the WCDMA sub-district as persistent district; B) select the GSM sub-district as persistent district.
As shown in Figure 2, the process that mode mobile terminal carries out cell selecting and gravity treatment in the present embodiment may further comprise the steps:
Step 203: mode mobile terminal resides in the WCDMA sub-district of current selected, simultaneously, the GSM transceiver of this mode mobile terminal by starting self to around all GSM sub-districts that can monitor signal carry out signal measurement; And, behind the signal that obtains all GSM sub-districts that monitor, the signal quality of these sub-districts is assessed.Wherein, the assessment level of signal quality can be according to the signal evaluation criterion in the commercial at present gsm system.
Step 204: according to the signal quality assessment result of step 203, judge whether that the signal quality of GSM sub-district satisfies resident standard, if having, then execution in step 207; Otherwise, execution in step 205.Wherein, described resident standard is the optimum persistent district evaluation criteria of agreement regulation.
Step 207: carry out from of the gravity treatment of WCDMA sub-district to the GSM sub-district, specific practice is: the signal quality that judges whether an above GSM sub-district satisfies the resident standard in sub-district, if, then select an only GSM sub-district as the target persistent district in all available GSM sub-districts, the standard of selecting suitable cell here is according to evaluation criteria in the commercial at present gsm system; If have only the signal quality of a GSM sub-district to satisfy the resident standard in sub-district, then directly selected this GSM sub-district is as the target persistent district.After determining the target persistent district, the cell reselection process of execution from the WCDMA sub-district to the GSM sub-district, that is: switch to determined target GSM sub-district from current resident WCDMA sub-district, this cell reselection process carries out according to defined standard procedure among the present 3GPP fully.
Step 208: judge whether the sub-district gravity treatment is successful, if mode mobile terminal sub-district gravity treatment success, then execution in step 209; Otherwise, execution in step 205.
Step 213: if the signal quality of all the GSM sub-districts that can monitor all is lower than the high threshold Up_Sir of signal quality, then current mode mobile terminal starts the WCDMA transceiver of self, begins to utilize the WCDMA transceiver that the signal quality of all WCDMA sub-districts that can monitor is measured on every side.
Then, current mode mobile terminal is carried out from current resident GSM sub-district to the switching of the selected resident WCDMA of target sub-district, i.e. cell reselection process, and this cell reselection process carries out according to defined standard procedure among the present 3GPP fully, return step 203 then, continue monitoring GSM cell signal; Otherwise if there are one or more GSM cell signal quality to be higher than the signal quality minimum threshold Low_Sir of setting, then execution in step 212.
In the process of monitoring GSM sub-district, the GSM sub-district that surpasses signal quality minimum threshold Low_Sir for signal quality, carry out sub-district gravity treatment between different GSM sub-district according to the cell reselection criteria of the gsm system of present commercialization, present commercial system is farthest inherited guaranteeing.
In addition, because when all GSM cell signals are lower than the high threshold Up_Sir of signal quality, started mode mobile terminal WCDMA transceiver, but trigger not carry out from the GSM sub-district before cell reselection process is carried out in the WCDMA sub-district, may reappear the situation that certain or certain several GSM cell signal quality are higher than the high threshold Up_Sir of signal quality, therefore, one timer can be set, when under WCDMA transceiver starting state occurring, having GSM cell signal quality to be higher than the high threshold Up_Sir of signal quality, start set timer, after if timer time arrives, the signal quality that still can maintain the GSM sub-district is higher than the high threshold Up_Sir of signal quality, then closes the WCDMA transceiver of current mode mobile terminal; Otherwise, continue to keep the WCDMA transceiver to be in starting state.
In the said process, high threshold Up_Sir of signal quality and signal quality minimum threshold Low_Sir determine according to signal quality situation in the current network, and such as according to the signal to noise ratio setting, these two threshold values can directly adopt the setting of stipulating in the 3GPP standard.
Adopt above-mentioned flow process, can make mode mobile terminal under idle pulley, carry out preferentially selecting the GSM sub-district as persistent district in cell selecting and the reuse adoption process; In the zone of GSM network and the network overlapped covering of WCDMA, mode mobile terminal is operated mainly under the GSM pattern, thereby the power consumption that can save mode mobile terminal under the idle condition postpone the stand-by time of mode mobile terminal.
Be in mode mobile terminal under the idle condition for residing in the GSM sub-district, when voice service triggers, then directly from the GSM network insertion voice service at place; When the business of initiating is data service, because the GSM network can not satisfy service quality (QOS) requirement of this data service, then the mode mobile terminal in the GSM sub-district can initiatively be initiated the process to the gravity treatment of WCDMA sub-district, earlier resident in the WCDMA sub-district, after resident success, in the WCDMA sub-district, finish the access of data service again.If mode mobile terminal resides in the WCDMA sub-district and is in idle condition, no matter be that voice service or data service trigger, can directly from current resident WCDMA sub-district, initiate service access.As seen, employing the present invention can't influence the use of customer service, simultaneously, because the present invention can guarantee preferential gravity treatment and resident to the GSM sub-district under the idle condition, preferentially use the GSM network so can guarantee user's voice service, and the WCDMA network is used in data service.Because mode mobile terminal uses the Speech Communication power consumption of GSM low in energy consumption more a lot of than WCDMA Speech Communication, therefore, adopts the present invention can improve the conversation and the stand-by time of mode mobile terminal greatly under the same battery capacity.
Above-mentioned implementation is not only applicable to mode mobile terminal, be equally applicable to multi-module mobile terminal, when certain portable terminal is supported multiple mobile communication system pattern, can for all patterns priority be set in advance, what its medium priority was the highest is exactly preference pattern, next is less preferred pattern, and the rest may be inferred.So, be under the preference pattern if this multi-module mobile terminal is current, and the signal quality of sub-district satisfies resident requirement under the preference pattern, then this multi-module mobile terminal is closed the transceiver of all other patterns in self, otherwise, open less preferred pattern transceiver successively, if signal can't satisfy, order is opened the transceiver of next priority mode again, and the rest may be inferred.Be not under the preference pattern if this multi-module mobile terminal is current, then this multi-module mobile terminal will be monitored the signal of all sub-districts that can monitor under the preference pattern in real time, if having satisfy resident requirement with regard to gravity treatment under preference pattern.
Lift an example, current have individual multi-module mobile terminal to support A, B, three kinds of mobile communication system patterns of C, and priority orders is followed successively by A from high to low, B, C, wherein A is a preference pattern, so, if sub-district and signal after the current multi-module mobile terminal start under the resident A pattern satisfy resident standard, then current multi-module mobile terminal is closed B in self, the transceiver of two kinds of patterns of C, if reside in after the current multi-module mobile terminal start in the sub-district under B or the C pattern, then this multi-module mobile terminal is monitored the sub-district under the A pattern, in case the sub-district under the A pattern is arrived in the energy gravity treatment, finishes immediately from the process of the selected target sub-district gravity treatment of current persistent district under the A pattern.During the sub-district, can between the sub-district under the current residing mode, carry out gravity treatment in gravity treatment not under the A pattern, also can between two kinds of patterns of B, C, select signal best finish the sub-district gravity treatment.When if current multi-module mobile terminal is under the A pattern sub-district, find that all cell signal quality that can monitor all can not satisfy resident standard, then open the transceiver of B pattern in the current multi-module mobile terminal earlier, judge whether that the sub-district under the B pattern satisfies resident standard, if satisfy, then gravity treatment is carried out in the minizone under the B pattern, monitor the cell signal under the A pattern simultaneously, at any time prepare sub-district under the gravity treatment meeting A pattern,, then open the transceiver of C pattern in the current multi-module mobile terminal again if resident standard can not be satisfied in the sub-district under the B pattern, judge whether that the sub-district under the C pattern satisfies resident standard, if can, then gravity treatment is carried out in the minizone under the C pattern, monitors the cell signal under the A pattern simultaneously, at any time prepare sub-district under the gravity treatment meeting A pattern, in such cases, can close the transceiver of B pattern, also can not close; If resident standard can not be satisfied in the sub-district under the C pattern, then or not gravity treatment, perhaps under A, B, C pattern, select the best sub-district of signal resident arbitrarily.
Multi-module mobile terminal proposed by the invention carries out the control method of cell selecting and gravity treatment under idle condition, be to want under 3G network and 2G network's coverage area and the situation of depositing, adopt a kind of controlling mechanism, do not influencing under the professional prerequisite of using, making multi-module mobile terminal can residently fast arrive proper cell.The present invention mainly utilizes the characteristics of 2G voice network and 3G data network, takes into full account work under the different mode difference of power consumption of multi-module mobile terminal, avoids multi-module mobile terminal that frequent cell reselection process takes place between 2G cell and 3G sub-district.The present invention adopts a kind of simple method, makes the multi-module mobile terminal priority task at 2G cell, simultaneously according to certain threshold criterion, judges whether 2G cell satisfies resident requirement, if do not satisfy resident again in the 3G sub-district; If satisfy then continue to reside in 2G cell, and close the 3G transceiver on the multi-module mobile terminal.Because the present invention has improved the multi-module mobile terminal possibility of working under the 2G pattern, therefore can reduce the energy loss of multi-module mobile terminal greatly, can make full use of simultaneously the characteristics of 2G network voice and 3G network data service, make the utilance of whole network reach optimum, also fundamentally avoided the frequently possibility of gravity treatment back and forth between 2G cell and 3G sub-district of multi-module mobile terminal.
