Embodiment
Core of the present invention is to be provided with the power-saving control unit and controls the application layer unit in portable terminal, upper-layer protocol unit and physical layer element enter the sleep state of low-power consumption or respectively it are waken up from sleep state, for fear of the increase of under the more frequent situation of portable terminal task, constantly sleeping and waking each layer cell moving power consumption of terminal up, further set the thresholding length of one's sleep, when portable terminal during in idle condition, calculate it from now on to the shortest time that needs between the last the executing the task, if should the time greater than the thresholding of the setting length of one's sleep, just by power-saving control unit controls application layer unit, upper-layer protocol unit and physical layer element enter the sleep state of low-power consumption.After the time is executed the task in arrival, at first wake physical layer element up and carry out the task that this need be carried out constantly, and then determine that according to the execution result of physical layer element whether waking the upper-layer protocol unit up enters operating state.At any time, if after trigger action from keyboard is received in the power-saving control unit, then wake the application layer unit immediately up and carry out corresponding operation.
The present technique field personnel know, after the terminal power-on, carries out the cell initial search process, finally enters into idle pulley.Under idle pulley, the main task of terminal is exactly to understand system information aperiodically, and adjacent cell is measured, and listens to the gravity treatment of paging and sub-district.The system information of Web broadcast and paging content were carried out with the fixed cycle, so terminal there is no need all system informations of constantly deciphering and the content of paging block, thereby can save the power supply power consumption of terminal greatly, improved the stand-by time of terminal.According to this principle, the present invention is provided with a power-saving control unit and controls application layer unit, upper-layer protocol unit and physical layer element and enter the sleep state of low-power consumption or respectively it is waken up from sleep state in portable terminal.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 1, Fig. 1 shows the theory diagram of portable terminal first embodiment of the present invention:
Usually, existing portable terminal is made up of several parts such as application layer unit, upper-layer protocol unit, physical layer element, keyboard, radio-frequency module, antennas.In the present invention, comprise this several parts equally, as shown in FIG., application layer cell S 1, upper-layer protocol cell S 2, physical layer element S3, keyboard S4, radio-frequency module S5, antenna S6 are arranged.In addition, in portable terminal of the present invention, also comprise with lower unit: power-saving control cell S 01, time calculating unit S02 and timer S03 execute the task.
When portable terminal was in idle condition, the time calculating unit S02 that executes the task calculated portable terminal from now on to the shortest time T that needs between the last the executing the task
i, notify power-saving control cell S 01 to make application layer unit, upper-layer protocol unit and physical layer element enter the sleep state of low-power consumption simultaneously, and according to this shortest time T
iBe provided with and startup timer S03, when timing arrives, that is to say elapsed time T
iAfter, timer S03 notice power-saving control cell S 01 is waken the task that physical layer element is carried out this moment up, after physical layer element is executed the task and finished, give power-saving control cell S 01, whether wake the upper-layer protocol unit up according to this result's decision by it with the execution result data passes.
The front is mentioned, and under idle pulley, the main task of terminal is exactly to understand system information aperiodically, and adjacent cell is measured, and listens to the gravity treatment of paging and sub-district.And in existing protocol, do not have the specifying measurement task executions constantly.Therefore, calculate portable terminal from now on to the shortest time T that needs between the last the executing the task at the time calculating unit S02 that executes the task
iThe time, only consider that portable terminal needs the moment of read system message or sub-district message and receipts beep-page message.Because the Web broadcast beep-page message is by transmission channel PCH (paging channel) and physical channel PICH (Page Indication Channel) broadcasting, wherein PICH and PCH pairing is used.PICH does not carry the data of transmission channel, but uses with transmission channel PCH pairing, the PCH channel (being mapped on the auxiliary Common Control Channel S-CCPCH) of following thereafter in order to indicate specific portable terminal whether to need to understand.The required information such as physical layer parameter, channel number and channel architecture of PICH channel configuration are by system information broadcast.The content of PICH channel is made up of a series of paging indicator, after terminal is understood the PICH piece, can determine the value of this paging terminal factor in the PICH piece, according to this value, terminal can learn whether be required to receive the PICH channel interior paging channel of paging block afterwards, to determine whether comprising in the beep-page message paging to this terminal.Therefore, calculating portable terminal from now on to the shortest time T that needs between the last the executing the task
iThe time, only consider the moment that portable terminal needs read system message or sub-district message and reads PICH.
No matter being system message, cell broadcast messages or the message of reading PICH, all is periodic, that is to say that each fixing cycle will read once this class message.But the cycle of every kind of message is different, and original position is generally also inequality, if the cycle of certain message is T (is unit with 5ms), start offset is O (is unit with 5ms), and the position of reading this message so is exactly O+N*T, and wherein N is an integer.
When power-saving control cell S 01 is waken physical layer element up, task of needing the notice physical layer element to carry out.If need to carry out read apparatus message or cell broadcast messages, after then physical layer element reads these message, send the message content that reads to power-saving control cell S 01, judge whether the message content that reads to be reported the upper-layer protocol unit by power-saving control cell S 01, report if desired, then power-saving control cell S 01 is waken the upper-layer protocol unit up, and the data content that physical layer element is received reports the upper-layer protocol unit and handles.If need to carry out the task of reading the PICH channel, when then physical layer element is read the PICH channel, carry out the measurement task, and send measurement result to power-saving control cell S 01, judge by power-saving control cell S 01 whether measured value has reached predetermined measurement thresholding.If measured value has reached predetermined measurement thresholding, then power-saving control cell S 01 is waken the upper-layer protocol unit up, makes physical layer element that measurement result is reported the upper-layer protocol unit; Simultaneously, physical layer element sends the PICH information that reads to power-saving control cell S 01, and by the value of power-saving control cell S 01 definite this paging terminal factor, whether according to this value, can learn needs to receive PICH channel PCH channel afterwards.Paging receiving message is then waken the upper-layer protocol unit up and is carried out corresponding action if desired.If power-saving control cell S 01 judges that according to the execution result of physical layer needs do not wake the upper-layer protocol unit up, then notify the time calculating unit of executing the task to carry out the calculating of next control time point.
Make T after application layer unit, upper-layer protocol unit and physical layer element enter sleep state in power-saving control cell S 01
iIn time period,, then wake the application layer unit up and obtain keyboard triggering task if power-saving control cell S 01 is received the triggering from keyboard.If the application layer unit finds that the triggering from keyboard is a task that needs insert, then notify power-saving control cell S 01, power-saving control cell S 01 is waken the operation that it is inserted up with being about to upper-layer protocol unit and physical layer element.
Under the frequent situation of task, constantly sleep and wake the increase that brings the control expense up for fear of portable terminal, also can set one the length of one's sleep thresholding, when the time calculating unit S02 that executes the task calculates the shortest time T that portable terminal needs between executing the task to the last time from now on
iGreater than this during thresholding, power-saving control cell S 01 just makes application layer unit, upper-layer protocol unit and physical layer element enter sleep state length of one's sleep, otherwise, make application layer unit, upper-layer protocol unit and physical layer element keep state of activation always.
Theory diagram with reference to portable terminal second embodiment of the present invention shown in Figure 2:
In this embodiment, threshold setting length of one's sleep cell S 04 is used to be provided with the threshold T length of one's sleep
t, this value can be set by user oneself in the position and the traffic carrying capacity of sub-district according to portable terminal.The threshold T length of one's sleep that comparing unit S05 is used for relatively being provided with
tAnd the portable terminal that calculates is from now on to the shortest time T that needs between the last the executing the task
