When the user will use mobile phone 10 to carry out wireless telecommunications, user's speech sound waves can be converted to electric signal via microphone 29A, signal via signal process device 16C is handled, the signal modulation of radio circuit 16B, transfer to a base station 28 by antenna 16A with the form of radio signals again, and can signal be transferred to another mobile phone by the signal switched service of base station 28.On the other hand, the radio signals (similarly being by the radio signals of another mobile phone by base station 28 switchings) that transfer to mobile phone 10 can be received by antenna 16A, again by radio link 16B demodulation, and in signal process device 16C, carry out necessary signal and handle the back and be converted to sound wave by loud speaker 29B and play back (or show by man-machine interface 18).Via above-mentioned running, the user of mobile phone 10 just can utilize mobile phone 10 to carry out radio communication.
But, as aforementioned, modern mobile phone has the additional function that other convenient user carries out data preparation, routing mostly except carrying out radio communication.In general, these functions are to be controlled by the man-machine interface of mobile phone by the user, and are carried out by the processor of mobile phone.When the user utilizes these additional functions of mobile phone, the user can not carry out radio communication mostly simultaneously, therefore, and when the user utilizes the additional function of mobile phone, mobile phone just can be stopped power supply and is responsible for carrying out the circuit of radio communication to transceiver module etc., to reduce power consumption.In addition, the user also not necessarily can carry out radio communication at once behind starting hand-set, and this moment, mobile phone also can enter so-called holding state, reduced the power consumption of transceiver module.But, because the user of mobile phone may move at any time, the environment of radio communication also can change at any time, in order to keep suitably getting in touch between mobile phone and base station, mobile phone still must carry out wireless link and exchange message (similarly being various parameters of radio communication or the like) by wireless communication timing and base station, is ready to the access capability to cordless communication network.In case when the user will carry out radio communication with mobile phone once again, mobile phone just can recover the access to wireless network apace.About this situation, please refer to Fig. 2 (and in the lump with reference to figure 1).Fig. 2 is the flow chart of power operation control flow 100 during mobile phone 10 operates.Flow process 100 is provided with the following step:
Step 102: beginning.After mobile phone 10 starts, just can carry out flow process 100.
Step 104: login the base station.After mobile phone 10 starts, search the base station that the better quality radio communication service can be provided; Just suppose that herein this base station is the base station 28 among Fig. 1.Behind the base station of decision contact, the processor 12 of mobile phone 10 can control transceiver modules 14 with the relevent information of radio signals transmit wireless communication to the base station 28, carry out the relevant authentication of cordless communication network or the like process, to login cordless communication network.Base station 28 also can be transmitted the message of response with radio signals, confirms login (or registration) of mobile phone 10.Also can exchange the various parameters of radio communication between base station 28 and the mobile phone 10.For instance, after base station 28 receives the radio signals that mobile phones 10 transmit, can adjust the watt level of follow-up radio signals according to signal power size notice mobile phone 10, the communication environment with 28 of matching with mobile phone 10, base station reaches preferable communication quality.In addition, a reception time data also can be transmitted to mobile phone 10 in base station 28, and in these data, mobile phone 10 can be obtained discontinuous (DRX, a Discrete Receiving) reception time interval, as the parameter of another radio communication.Under the battery saving mode of mobile phone 10 in standby, if according to this reception time interval to base station 28 senders repayment, carry out wireless link, just can keep the state of logining to cordless communication network.The relevant running of the time interval of reception therewith will be further discussed in follow-up description.
Step 106: whether enter battery saving mode.If the user of mobile phone 10 temporarily also need not use mobile phone 10 to carry out radio communication after step 102 start, mobile phone 10 just can enter the battery saving mode of standby, flow process 100 also can with proceed to step 108.If the user will carry out radio communication, just can proceed to step 124.
Step 108: processor 12 can be set timer 26 according to the reception time interval of being transmitted by base station 28 after entering battery saving mode.In addition, processor 12 also can determine a power saving time interval according to the operating state of mobile phone 10 itself and user's instruction, and according to this power saving time set timer 26.As previously mentioned, mobile phone 10 also can carry out other additional function except carrying out radio communication.In this step 108, mobile phone 10 can be according to the additional function that it carried out, the decision power saving time.For instance, the display that the user can set man-machine interface 18 regularly shows different image frames, with the function as screen protection.Display upgrades the time interval between image frame at every turn, can be as a power saving time interval.In general, the power saving time interval can be less than the reception time interval.
Step 110: after the end step 108, mobile phone 10 can carry out the running under the battery saving mode.Processor 12 meetings this moment are set electric power controller 20 and only be provided electrical power to timer 26; And electrical management device 20 also will stop to provide clock that electric power and clock generator 22 produce to other circuit in the mobile phone 10, and especially transceiver module 14.This moment, the power consumption of mobile phone 10 will significantly reduce, and entered to battery saving mode.And timer 26 also can pick up counting according to the power saving time interval, the reception time interval.
Step 112: mobile phone 10 is after step 110 enters to battery saving mode, and the timer 26 in the mobile phone 10 also can continue timing, has checked whether institute's elapsed time has reached the power saving time interval since step 110 is carried out.If elapsed time has arrived the power saving time interval, just can proceed to step 114.In other words, the time and the power saving time interval definable that are begun to carry out by step 110 go out the power saving time, make the lead time of the time phase difference that power saving time and step 110 are carried out be this power saving time interval.After arriving the power saving time, timer 26 will trigger flow process 100 and proceed to step 114.
Step 114: the time since timer 26 is found to be undertaken by step 110 in step 112 has arrived the power saving time interval, will send one and start signal to electrical management device 20 and processor 12, so that electrical management device 20 begins each circuit of mobile phone 10 is provided the clock of electric power and clock generator 22 once again, and the processor 12 that obtains supply of electric power also will begin carry out step 108 in default running.For instance, the brought forward example, the display in the processor 12 may command man-machine interfaces 18 upgrades image frame.After processor 12 finishes corresponding running, can get back to step 108; If be necessary that processor 12 can be set the new power saving time interval, sets timer 26 once again, and after step 110, reenter battery saving mode.And timer 26 can check repeatedly in step 112 once again also whether the power saving time interval arrives.
Step 116: when whether the 6 calculating power saving time intervals of timer 2 arrive, can check also whether institute's elapsed time has arrived the reception time interval since step 110 is carried out simultaneously.In other words, the time and the reception time interval from step 110 beginning can define the reception time; And timer 26 can continue timing in step 110 beginning back, checks whether arrived the reception time.If arrive the reception time, timer 26 will trigger flow process 100 and enter to step 118.
Step 118: be similar to step 114, time is up when timer 26 is found reception in step 116, will start signal with one makes electrical management device 20 and processor 12 break away from battery saving mode, this moment, electrical management device 20 can be supplied the transceiver module 14 of the clock of electric power and 22 generations of clock generator to each circuit, especially the transmitting/receiving wireless electric signal of mobile phone 10 once again.
Step 120: the processor 12 that obtains supply of electric power in step 118 can send a wireless contact signal to base station 28 by control transceiver module 14, with the contact base station, keeps the state of logining to cordless communication network.And base station 28 also can respond the signal of a correspondence behind the signal of receiving mobile phone 10, and the contact signal that reaches base station 28 with foundation mobile phone 10 is 10 pairs of employed parameters of cordless communication network access of new cell-phone more.Wherein, a new reception time data can be transmitted once again to mobile phone 10 in base station 28, to indicate a new reception time interval to mobile phone 10.Mobile phone 10 can be got back to step 108 after the reception time interval in reading the reception time data, resets timer 26 according to this new reception time interval, and gets back to step 110, allows mobile phone 10 return to low power consumption running under the battery saving mode.By the time that the new reception time interval and step 110 begin once again, definable goes out a new reception time again; Through the setting in the step 108, timer 26 can check in step 116 constantly also whether the new reception time arrives.
Step 122: carry out step 112, at 116 o'clock at timer 26,, just can proceed to step 124 if mobile phone 10 will break away from battery saving mode (for example the user is interrupted battery saving mode, begin to carry out radio communication with mobile phone 10).
Step 124: carrying out other outer running of battery saving mode, mainly is radio communication.This moment, transceiver module 14 will obtain supply of electric power and the transmitting/receiving wireless electric signal.
For further specifying the situation that flow process 100 is carried out, please continue with reference to figure 3 (and in the lump with reference to figure 1, Fig. 2).When Fig. 3 carried out for flow process 100 among Fig. 2, correlation step was carried out the schematic diagram of time; The transverse axis of Fig. 3 is the time.Suppose that at time point tp0 flow process 100 begins to carry out.At time point tp0 to tp1, mobile phone 10 can carry out step 104, logins the cordless communication network of base station 28, and draws a reception time interval TpD1 by the reception time data that base station 28 is transmitted.If the user of mobile phone 10 also need not carry out radio communication with mobile phone 10 behind time point tp1, mobile phone 10 will proceed to step 108, to set timer 26, enter the running of step 110 under battery saving mode at time point tp1 immediately according to a power saving time interval Tps1 and reception time interval TpD1; And timer 26 is also picked up counting by time point tp1.By time point tp1 and power saving time interval Tps1, reception time interval TpD1, just can determine a power saving time tp2a and a reception time tp4 in the equivalence respectively; Make the time difference between power saving time, reception time and time point tp1, just equal power saving time interval Tps1 and reception time interval TpD1 respectively.Arrived time point tp2a, timer 26 is found power savings, and time is up, will trigger electrical management device 20, processor 12 comes into operation, and carry out step 114.And in Fig. 3, the oblique line pattern between time point tp1, tp2a, just representative is between this two time point, and mobile phone 10 is under the battery saving mode that need not start transceiver module 14.Suppose that step 114 finishes at time point tp2b, flow process 100 will be got back to step 108.Suppose that herein processor 12 defines a new power saving time interval Tps2 once again according to the needs of follow-up running, and in step 108, reset timer 26, proceed to step 110 immediately, make mobile phone 10 get back to battery saving mode.Time point tp2b according to power saving time interval Tps2 and step 110 are restarted just can draw a new power saving time tp3a in the equivalence; And timer 26 can reexamine whether arrived this power saving time tp3a in step 112.At the same time, timer 26 still can not be subjected to the influence of power saving time timing, and whether the continuation review time has arrived reception time tp4.
Arrived time point tp3a, timer 26 is judged power saving, and time is up, will proceed to step 114 once again, carries out necessary function by processor 12.Suppose that behind time point tp3b flow process 114 finishes, mobile phone 10 can enter the power saving running of low power consumption again at time point tp3b.Arrived time point tp4, timer 26 can be judged reception in step 116 time is up, and can start electrical management device 20 and processor 12 in step 118; And processor 12 will be controlled transceiver module 14 and carries out the contact signal is sent in base station 28 in step 120, carries out wireless link, to confirm the state of logining of 10 pairs of cordless communication networks of mobile phone; And base station 28 also can be with response radio signals response, and the parameter of 10 pairs of cordless communication network accesses of new cell-phone more.Suppose that this moment, base station 28 transferred to mobile phone 10 with a new reception time data, draw up a new reception time interval TpD2.And flow process 100 can proceed to step 108, resets the 6 counting reception times of timer 2 according to reception time interval TpD2; And carry out step 110 at time point tp5 immediately, (with respect to the reception time interval, required time of step 11 8,120 to 108,110 is quite short in fact to come back to battery saving mode; In other words, time point tp4, tp5 are quite approaching in fact).According to time point tp5 and new reception time interval TpD2, also just determined a new reception time tp7 in the equivalence; And timer 26 will be in step 116 review time whether arrived the reception time.In addition, the power saving time timing that timer 26 still can determine according to the power saving time interval so that electrical management device 20, processor 12 can begin during the time to start in power saving, is carried out necessary function and running.For instance, when another power saving time of time point tp6a arrived, timer 26 can make flow process 100 proceed to step 114 once again, and gets back to step 110 at time point tp6b.Simultaneously, whether timer 26 still can continue to count the reception time and arrive, be not subjected to the power saving time reset, the influence of timing.
Arrived reception time tp7, timer 26 triggers flow process 100 once again and proceeds to step 118,120, and mobile phone 10 can start transceiver module 14 and base station 28 exchange radio signals once again, keeps the state of logining, and obtains a new reception time interval TpD3.Along with flow process 100 gets back to 108,110 by step 118,120, the time point tp8 and the reception time interval TPD3 that carry out according to step 110, also go out another reception time tp9, and timer 26 can restart in step 116 to new reception time timing, by that analogy with regard to definable.Certainly, mobile phone 10 also might be contained the reception time during step 114 is carried out additional function.For instance, when processor 12 was begun to carry out step 114 by time point tp3a, the time that step 114 is carried out may be longer, and the time point tp3b that step 114 is finished falls within after the time point tp5.In the case, timer 26 still can proceed to step 118 at time point tp4, and prompting processor 12 should carry out step 120, exchanges radio signals to keep the state of logining with base station 28.Only the term of execution of step 114, electrical management device 20 should start (at time point tp3a), and just needn't start electrical management device 20 once again in the step 118.
By above discussion as can be known, when mobile phone 10 is in standby or carries out additional function outside the radio communication, timer 26 still can trigger processor 12 according to the reception time interval of base station 28 indications, send the contact signal by processor 12 control transceiver modules 14 to base station 28, to keep the state of logining to cordless communication network by intermittence, discontinuous/reception.In fact, base station 28 can be considered the time slot (time slot) that open for mobile phone 10 base station 28 to the reception time interval of mobile phone 10 indications; Determine reception during the time at mobile phone 10 according to the reception time interval, the signal that base station 28 equally also can be transmitted at this reception time waiting mobile phone 10.Because base station 28 may provide the service of cordless communication network access for a plurality of different mobile phones, so will carry out time-related multitasking, handles the wireless network access matters of different mobile phones in the different time.By to the indicated reception time interval of each mobile phone, base station 28 just can be for different handset allocation different time slots, realize a plurality of mobile phones in time-related control tasks.Yet because the characteristic of mobile phone wireless communication, the wireless communications environment between mobile phone, base station also can change in time.For instance, the user of mobile phone possibility shift position, or some barrier appears between mobile phone, the base station; The mobile phone number that relies on same base station to handle radio communication also may change in time.So, when mobile phone 10 according to the reception time interval when each reception time and base station 28 are got in touch, base station 28 all can be according to the wireless communication parameters of the status update mobile phone 10 of radio communication, and adjusts the reception time interval.
But, regulation according to existing radio communication specification, if in certain specific reception time of being drawn up according to a reception time interval TD, the contact signal (for example being that the contact signal that mobile phone 10 sends to base station 28 is not received by base station 28 for some reason) of mobile phone 10 is not received in base station 28, a time slot still can be opened for mobile phone 10 every a reception time interval TD in base station 28, waits for the wireless link signal that mobile phone 10 transmits once again.And the contact signal that sends when mobile phone 10 does not obtain the response of base station 28, and mobile phone 10 also can transmit the contact signal once more every a reception time interval TD, recovers to get in touch with base station 28 attempting, and keeps the state of logining to cordless communication network.About this kind operation, refer again to Fig. 2.For instance, mobile phone 10 sends the contact signal at time point tp7 to base station 28, and base station 28 responds and indicates a reception time interval TpD3, mobile phone 10 also to enter battery saving mode in time point tp8, also just draw up a new reception time tp9 in the equivalence, and pick up counting by timer 26.Supposed time point tp9, mobile phone 10 sends the contact signal according to predetermined running, and the contact signal that mobile phone 10 transmits is not but received in base station 28, and this moment, base station 28 just can't respond mobile phone 10.And base station 28 meetings are that mobile phone 10 is opened time slots through (time point tp10 just) behind another section reception time interval TpD3 once again, wait for the contact signal that sends separately of mobile phone 10.Similarly, mobile phone 10 is not but received the signal of base station 28 responses after time point tp9 sends the contact signal, can (being at time point tp10 equally) transmit the contact signals to base station 28 once again behind another section reception time interval TpD3 yet.In other words, this moment, time point tp10 can become the new reception time again, timer 26 can check in step 116 whether this reception time arrives, and, transmit wireless contact signals (being step 118,120) with transceiver module 14 to base station 28 once again at time point tp10 startup electrical management device 20, processor 12.If mobile phone 10 is not received by base station 28 still that at the contact signal that time point tp10 sends base station 28, mobile phone 10 can be drawn up a new reception time tp11 according to time point tp10 once again according to previous reception time interval TpD3.According to the regulation of existing radio communication specification, contact can be attempted setting up in time point tp11 once again in mobile phone 10, base station 28.Suppose that at time point tp11 the contact signal that mobile phone 10 sends is received by base station 28 finally, base station 28 will respond mobile phone 10, keeps the state of logining of 10 pairs of cordless communication networks of mobile phone, and to mobile phone 10 indication another reception time interval TpD4.And mobile phone 10, base station 28 can carry out wireless link once again in the next reception time that reception time interval TpD4 defines.In brief, successfully do not setting up wireless link according to a certain reception time interval in a certain specific reception time, will attempt setting up wireless link once again at the time point after this a plurality of reception time interval specific reception time of interval when mobile phone, base station.Similarly be at above-mentioned example, the lead time between time point tp9, tp10 and tp11 and time point tp8 (mobile phone 10 is obtained the time of reception time interval TpD3) just is respectively one times of reception time interval TpD3, twice and three times.
Keep the state of logining of 10 pairs of cordless communication networks of mobile phone in above-mentioned this mode, discontinuous wireless link is carried out every a reception time interval between only needing off and in 28 of mobile phone 10 and base stations, can keep the state of logining to cordless communication network.And between between two wireless links every during in, mobile phone 10 just needn't be opened transceiver module 14 and carry out wireless link, also just can save a large amount of power of transmitting/receiving wireless electric signal.If mobile phone 10 in above-mentioned battery saving mode, interrupt fully with base station 28 get in touch and login state, then when the user will use mobile phone 10 to carry out radio communication, mobile phone 10 will carry out step 104 again, expend many times and power and search suitable base station again, also to carry out logining of cordless communication network again, on the contrary the user be made troubles.
Though mobile phone 10 can enter under the battery saving mode when standby or user use the additional function of mobile phone with flow process known among Fig. 2, avoid carrying out continuously the spent power of radio communication, but to carry out discontinuous wireless link according to the reception time interval of base station indication, so not only lack the elasticity on the power dispatching, under the prerequisite of keeping state that cordless communication network is logined, also can't further reduce the power of the required consumption of wireless link.Though there is mobile phone to have the function of refusing incoming call at present, in fact this kind mobile phone still can be according to the known procedures 100 of Fig. 2, carries out wireless link according to the reception time interval of base station indication.In other words, the function of its refusing incoming call, still can be because of carrying out discontinuous wireless link consumed power, can not reduce the power that wireless link consumed because of refusal communication veritably.
Summary of the invention
Therefore, main purpose of the present invention, be to provide a kind of method and relevant apparatus that can under battery saving mode, further reduce discontinuous wireless link power consumption, with under the prerequisite of keeping state that wireless network is logined, enter mobile phone is used more flexible, power consumption battery saving mode still less.
In known technology, known mobile phone must be set up wireless link in specific time and base station, to keep the login state of mobile phone to cordless communication network according to the reception time interval of base station indication under battery saving mode; This kind battery saving mode lacks flexibility in utilization, and discontinuous wireless link still can consume suitable power.
In the present invention, mobile phone of the present invention can multiply by many times as a virtual reception time interval with the reception time interval of base station indication under battery saving mode, draw the reception time according to this virtual reception time interval again, carry out discontinuous wireless link with the base station.According to the regulation of existing radio communication specification, carry out discontinuous wireless link in the time interval in many times of the reception time intervals, also still can keep the login state of mobile phone to cordless communication network; And because the present invention elongates the time between discontinuous wireless link, the power that the unit interval internal cause is carried out the required consumption of wireless link also just can reduce than known technology.In brief, the present invention can directly be implemented in existing radio communication specification, can not only save more energy than known technology, also still can keep the state of logining to cordless communication network simultaneously under battery saving mode.The present invention also can set different battery saving modes, selects the reception time interval of base station indication be multiply by different multiples to draw the different virtual reception time under different battery saving modes, more increases the elasticity in the use.
