Based on the description of said method embodiment, the present invention proposes a kind of preferred embodiment, specific as follows: with reference to Fig. 3, show the flow chart of a kind of terminal sleeping method of the present invention, the present embodiment specifically can comprise the following steps:
Step 200, judges whether terminal meets dormancy condition.
After the physical layer of terminal meets dormancy condition, DSP can send sleep request to ARM, ARM after receiving the sleep request that DSP sends, and ARM judges whether self meets dormancy condition.Judge in the present embodiment whether terminal meets dormancy condition, specifically can comprise: judge whether the ARM of terminal meets dormancy condition.Specifically can by judging whether the LTE business of the ARM of terminal in current DRX cycle completes, judge whether the ARM of terminal meets dormancy condition, when the Long Term Evolution business of ARM in current DRX cycle of terminal completes, judge that the ARM of terminal meets dormancy condition; When the LTE business of ARM in current DRX cycle of terminal does not complete, judge that the ARM of terminal does not meet dormancy condition.
Step 202, when terminal meets dormancy condition, obtains the park mode corresponding with the terminal type of terminal.
Terminal type comprises: single-mode terminal, first kind multimode terminal and Second Type multimode terminal, wherein, power mode under single-mode terminal type corresponding A RM, first kind multimode terminal corresponding A RM frequency reducing pattern, Second Type multimode terminal corresponding A RM normal frequency pattern; Since dissimilar terminal is different for the demand of low-power consumption, and ARM is responsible for the low-power consumption management of whole LTE baseband chip and other modules, therefore the low-power consumption difference of different terminals type is mainly reflected on the sleep mode of ARM, the present embodiment is according to the difference of ARM sleep mode, propose multiple different terminal dormancy mode, comprising: power mode, ARM frequency reducing pattern and ARM normal frequency pattern under ARM.The park mode that terminal types different in the present embodiment is corresponding different, terminal can obtain the park mode corresponding with the terminal type of terminal, and different park modes is specific as follows:
Power mode under ARM, is used to indicate when terminal type is single-mode terminal, makes the ARM power-off of terminal.Single-mode terminal only has a LTE module, therefore when LTE module does not need work, can make LTE module power-off, therefore for single-mode terminal, selects park mode corresponding to be with it power mode under ARM.
ARM frequency reducing pattern, is used to indicate when terminal type is first kind multimode terminal, and the ARM frequency reducing of terminal is run.Multiple module is had in the LTE baseband chip of first kind multimode terminal, and have in these modules and between the 2G/3G module in terminal some be coupled (such as USIM acts on behalf of), when LTE module does not need work, other modules are still in running order, but be only limitted to some shirtsleeve operations such as USIM agency, now LTE module can not power-off; And ARM just can meet the operation of USIM agency when lower frequency, therefore for first kind multimode terminal, park mode corresponding is with it selected to be ARM frequency reducing pattern.
ARM normal frequency pattern, is used to indicate when terminal type is Second Type multimode terminal, and the ARM normal frequency of terminal is run.Multiple module is had equally in the LTE baseband chip of Second Type multimode terminal, these modules not only need there is coupled relation between 2G/3G module, and to need and WIFI module carries out communication, complete the transfer of WIFI data, now LTE module equally can not power-off; And the transfer of WIFI data, need ARM to keep normal frequency just can complete, therefore for Second Type multimode terminal, select park mode corresponding to be with it ARM normal frequency pattern.
Step 204, calculates time of starting apart from next DRX cycle of current DRX cycle, and using time of calculating as dormancy time.
Terminal is at the LTE correlated process (Paging of current DRX cycle, cell measurement, cell detection, up-downgoing data service etc.) complete after, (be according to configurations such as Paging cycle during RRC_IDLE according to DRX relevant configuration, according to the configuration of DRX Setup relevant parameter during RRC_CONNECT) calculate the time that current time starts apart from next DRX cycle, and using time of calculating as dormancy time.
Step 206, carries out dormancy process according to the park mode obtained in dormancy time.
Dormancy process can be carried out according to the park mode obtained in dormancy time in the present embodiment, wherein carry out dormancy process according to the park mode obtained, specifically can comprise following sub-step:
Sub-step 1, when park mode is power mode under ARM, the RF unit of closing a terminal, the power supply of FPGA, DSP and ARM, make the Double Data Rate synchronous DRAM of terminal (Double DataRate, DDR) enter self-refresh battery saving mode; The park mode obtained when being power mode under ARM, illustrates that terminal type is single-mode terminal, and when meeting dormancy condition, LTE module can power-off, the RF unit on the LTE baseband chip of namely closing a terminal, the power supply of FPGA, DSP and ARM.
Sub-step 2, when park mode is ARM frequency reducing pattern, the RF unit of closing a terminal, the power supply of FPGA and DSP, the ARM frequency reducing of control terminal runs, and stops protocol stack relevant to LTE in scheduling ARM, the DDR of terminal is normally run; When the park mode obtained is ARM frequency reducing pattern, illustrate that terminal type is first kind multimode terminal, when meeting dormancy condition, ARM frequency reducing runs, close the power supply of whole RF unit, FPGA and DSP, stop protocol stack relevant to LTE in scheduling ARM, the DDR of terminal is normally run.
Sub-step 3, when park mode is ARM normal frequency pattern, the RF unit of closing a terminal, the power supply of FPGA and DSP, the ARM normal frequency of control terminal is run, and stops protocol stack relevant to LTE in scheduling ARM, the DDR of terminal is normally run.When the park mode obtained is ARM normal frequency pattern, illustrate that terminal type is first kind multimode terminal, when meeting dormancy condition, control ARM normal frequency is run, and stops protocol stack relevant to LTE in scheduling ARM, the DDR of terminal is normally run.
Above-mentioned three sub-steps describe dormancy process corresponding to three kinds of park modes (under ARM power mode, ARM frequency reducing pattern and ARM normal frequency pattern), can understand the difference of three with reference to following table 1 better.
Table 1 three kinds of park mode contrasts
As can be seen from Table 1, under ARM power mode, ARM frequency reducing pattern and ARM normal frequency pattern dormancy process in, all close the power supply of RF unit, FPGA and DSP, the RF unit of closing a terminal in the present embodiment, the power supply of FPGA and DSP, specifically can realize in the following manner:
First, the DSP of terminal calculates time that the next discontinuous receiving cycle of current distance starts as dormancy time; Secondly, the DSP of terminal closes the power supply of RF unit, and according to dormancy time configuration PMU, PMU according to dormancy time, uses RTC to carry out dormancy counting; Finally, after the power supply of the DSP closedown FPGA of terminal, DSP powered-down enters resting state.
In the present embodiment, although terminal type is different with the sleep mode of selection, for terminal, when dormancy time terminates time, all need to be waken up.Wake terminal in the present embodiment up and specifically can comprise following sub-step:
Sub-step 1, PMU exits to count and send hardware interrupts message wakes ARM up.
After sub-step 2, ARM receives hardware interrupts message, exit current park mode, and wake DSP up.
Sub-step 3, DSP exits park mode, and recovers the power supply of FPGA and RF unit.
Sub-step 4, DSP sends to wake up and indicates message to ARM, and so far terminal is waken up from resting state, starts the LTE process in next DRX cycle.
In LTE system, according to whether there is wireless heterogeneous networks connection, can be off-grid state by the state demarcation residing for UE, idle condition (RRC_IDLE) and connection status (RRC_CONNECT).Clear and definite statement and requirement has been had to the DRX technology under idle condition (RRC_IDLE) and connection status (RRC_CONNECT) in the LTE related protocol of current 3GPP, namely when idle condition, UE is according to the paging cycle carried in Sib2, the parameters such as nB and UE ID, the PDCCH of the monitoring P-RNTI scrambling of property performance period.When connection status, RRC issues the configuration of the various DRX parameter of signaling UE and timer, and UE carrys out execution cycle property by the cooperation of various timer and monitors PDCCH.
It should be noted that, the terminal in the embodiment of the present invention can comprise UE or have other equipment of identical identity function.
Below in conjunction with the low-power consumption DRX scheduling flow figure under RRC_IDLE and RRC_CONNECT shown in Fig. 4, the dormancy method shown in Fig. 3 is described, specific as follows:
Step 1, ARM selects park mode according to terminal type.
When terminal type is single-mode terminal, power mode under selection ARM, ARM power-off enters resting state; When terminal type is first kind multimode terminal, select ARM frequency reducing pattern, after ARM enters resting state, frequency reducing runs; When terminal type is Second Type multimode terminal, select ARM normal frequency pattern, after ARM enters resting state, normal frequency is run.
Step 2, LTE PHY completes LTE correlated process in current DRX cycle, and calculates time that current time starts apart from next DRX cycle as dormancy time.
Because DSP with FPGA has been in the relevant work of LTE physical layer, therefore both are synthesized LTE PHY.Specifically by the LTE correlated process (Paging of DSP at current DRX cycle, cell measurement, cell detection, up-downgoing data service etc.) complete after, (be according to configurations such as Paging cycle during RRC_IDLE according to DRX relevant configuration, according to the configuration of DRXSetup relevant parameter during RRC_CONNECT) calculate time that current time starts apart from next DRX cycle as dormancy time, i.e. T_Sleep, and send sleep response message (SLEEP_REQUEST message) to ARM.
Step 3, ARM receives the sleep request that LTE PHY sends;
Specifically send sleep request (Sleep Request) by the DSP in LTE PHY, ARM receives the sleep request that DSP sends.
Step 4, ARM judges whether this ARM can carry out dormancy.
After ARM receives the sleep request of LTE PHY transmission, judge whether this ARM can carry out dormancy, namely ARM judges whether self meets dormancy condition, if ARM meets dormancy condition, just can carry out dormancy, if ARM does not meet dormancy condition, then can not carry out dormancy.
Step 5, ARM sends sleep acknowledge message to, LTE PHY.After ARM judges that self (this ARM) can carry out dormancy, send sleep acknowledge message (Sleep Confirm) to LTE PHY.
Step 6, after LTE PHY receives the sleep acknowledge message of ARM transmission, closes radio frequency.Specifically received the sleep acknowledge message of ARM transmission by the DSP in LTE PHY after, close RF unit.
Step 7, LTE PHY configures PMU according to dormancy time.Specifically configure PMU by the DSP in LTE PHY.
