Embodiment 2:
Please refer to Fig. 4.
The embodiment of the invention provides a kind of method for reducing communication unit battery saving mode power consumption, the communication unit UE packets
Include RTC timer module and RTC_RAM module, which comprises
Step S401, when the described communication unit UE enters battery saving mode PSM, it is in Deeper Sleep state.
Step S402, the RTC timer module power supply is kept, wherein the RTC timer module is used for timing, calls out
It wakes up.
Step S403, by the information preservation in the RTC_RAM module to separate storage region；Wherein, the packet
Modem information and AP information are included, the Modem information includes protocol information and portion radio frequency information.The separate storage region
It is defined in the system Flash, dedicated for saving the information in RTC_RAM module, the separate storage region can be into
The repetition of row data information is erasable, that is, wipes the information of previous write-in, then this data information is written.
Step S404, the RTC_RAM module for power supply is disconnected.

It is that simulation Flash erase/write test is carried out to the present embodiment below.
Data in the RTC_RAM module only have several K, and the function in erasable process is tested in simulation Flash erase/write operation
Consumption, example are as follows:
000020 start erase 4k data time=1860
000021 end erase 4k data time=1865
000046 start write 4k data time=2237
000047 end write 4k data time=2240
Above chronomere is 10ms, then as can be seen that the process about time-consuming 5*10=50ms wiped, the process consumption write
When 3*10=30ms, erasable data are all 4K.
It reads the block message in Flash and another region is written, the write back data of Flash will be written to RTC_ in simulation
The process of RAM module.It is as follows:
000072 start read 4k data time=2584
000073 end read 4k data time=2584
000046 start write 4k data time=2237
000047 end write 4k data time=2240
The time of 4K data is read less than 10ms, the time for writing 4K data is 30ms.Referring to the data of test Flash chip:
Reading and writing, the operation average current 5mA of wiping or so.The then battery capacity that above process expends are as follows: 0.17uAH.
It is forced in test software code after breaking the electricity of the RTC_RAM module under PSM mode, after tested, current reduction
2.6uA or so has been arrived, 1uA is about reduced.
By measuring and calculation, after the method for the embodiment of the present application, the battery capacity of consumption in communication equipment one day subtracts
Small is 97.79uAh.It is as shown in the table:
Comparison is as shown in the table using the power consumption before the method optimization of the embodiment of the present application and after optimization:
| Contents of decrement before optimizing | Optimize post consumption capacity | Reduce capacity | Reduce percentage |
| 121.79uAh | 97.79uAh | 24uAh | 19.7% |
The capacity that comparison write-in, write-back expend is as follows: with the capacity for reducing PSM Save power consumption
| Operation | It is written, writes back power consumption | The power consumption that RTC_RAM goes electricity to save |
| The battery capacity of consumption in one day | 0.17uAh | 24uAh |
Above data comparison is it can be found that be write-in using the battery capacity saved after the method optimization of the embodiment of the present application
Write back data expends 141 times of battery capacity, battery capacity optimization 19.7%.And it because being related to frequent Flash erase/write, examines
Consider the loss of Flash, if erasable, 10 years erasable numbers 3650 times once a day, erasable time hundreds of thousands of for Flash
It can ignore for number.
