Interaction.It is illustrated in figure 3 the oscillogram that UE in the embodiment of the present invention is respectively at CDRX patterns and power consumption corresponding to DRX mode；
When the data service of UE execution in need, UE is waken up, and after the data service that above-mentioned needs perform, UE enters
CDRX patterns, when CDRX mode durations reach, which switches to DRX mode.
As shown in fig.4, in the embodiment of the present invention, the detailed process for reducing UE power consumptions is：
Step 400：RRC connection status is between UE and network side, and it is current between the UE and above-mentioned network side
After the data service of execution, the CDRX mode duration information that the network side issues is obtained.
In the embodiment of the present invention, need the data service that performs when existing between UE and network side, and UE and network side it
Between when not setting up RRC connections, UE will send RRC connections to network side and establish request, and network side, which is based on the RRC connections, to be established and ask
Being fed back to UE allows connection establishment response message, after UE obtains the permission connection establishment response message, that is, establishes and network side
RRC connections.At this time, UE can perform above-mentioned data service, and after the data service, UE obtains CDRX mode durations
Information, the CDRX mode duration information are issued by network side, and the corresponding time length of the CDRX mode duration information
Spend and pre-set for t, such as t=120 second；Also, in CDRX mode durations, UE and network side are RRC connection status.Can
Choosing, from above-mentioned data service finish time with acquisition network side issue CDRX mode duration information it is corresponding at the time of between
Time difference be less than 30 seconds, the specific time is specifically judged by network side according to the service conditions of UE.
Optionally, a CDRX timer is locally configured in UE, the duration information of the timer is configured to CDRX patterns and holds
The corresponding time span of continuous temporal information., will be local when the execution initial time of above-mentioned UE any one data service reaches
CDRX timers reset, after above-mentioned any one data service is finished, i.e., the CDRX patterns that are issued according to network side
Duration Information again for above-mentioned CDRX timers distribute duration information, and for the CDRX timers distribution duration information still
For the corresponding time span t of CDRX mode duration information.
Step 410：According to the operating parameter of UE, the corresponding time length of CDRX mode duration information in acquisition is judged
When UE need not perform data service in degree, the RRC connections of UE and network side are disconnected.
In the embodiment of the present invention, the acquisition methods of the operating parameter of above-mentioned UE have two kinds.First way is by network side
Obtain the operating parameter of UE；The second way is that the operating parameter of UE is obtained by UE.
The operating parameter that UE is obtained using first way is specific as follows：Network side is obtained by net according to network performance parameter
The data business volume that the lateral UE of network is sent in the data service that network side is initiated, according to the data business volume, counts each respectively
The corresponding business datum of item data business reaches the corresponding arrival moments of above-mentioned UE, and during arrival that all data services are corresponding
The operating parameter as the UE is carved, and the operating parameter of the UE is sent to above-mentioned UE.For example, network side runs speed according to UE
Degree, CELL ID（Cell Identifier；Cell ID）Institute is obtained Deng any one in network performance parameter and combinations thereof
There is the corresponding arrival moment of data service.
The operating parameter that UE is obtained using the second way is specific as follows：UE searches the application program being locally currently running,
Obtain all application programs there are data service with network side；Count the data service of the above-mentioned all application programs found
The cycle is performed, and the data service of all application programs found is performed into operating parameter of the cycle as UE.Second
In kind mode, the data service execution cycle of the application program of UE local runtimes can determine according to the characteristic of the application program,
For example, when in UE local runtime instant messenger application programs, the data service of the instant messenger application program is held
The row cycle be 3 minutes, that is, represent the every data services for performing the instant messenger application program in 3 minutes of UE, with network side into
The interaction of the corresponding business datum of the above-mentioned data service of row.
From the above process, during using first way, the operating parameter of the UE of acquisition is actively to be initiated by network side
The corresponding arrival moment of data service；During using the second way, the operating parameter of the UE of acquisition is according to local fortune by UE
The execution cycle of data service performed by capable application program.Therefore, can using first way obtain arrival moment as
The operating parameter of UE；Can also be according to operating parameter of the execution cycle that the second way obtains as UE.
When obtaining the operating parameter of UE using the second way, UE, which is searched, to be locally currently running, and is existed with network side
All application programs of data service；UE is respectively each application program configuration timer found, and according to finding
The data service of each application program perform the cycle, be respectively that each timer for being configured sets corresponding perform
Duration information；When any one above-mentioned timer expiry, UE is the data industry that can perform the corresponding application program of the timer
Business.For example, if the execution cycle that application program one corresponds to data service is 3 minutes, for the timing of the application program one configuration
The execution duration information that device is set is 3 minutes, after the one currently performed data service of application program, is reached within 3 minutes
When, i.e., after the configured timer expiry of above application program one, perform the one corresponding data service of application program.
In the embodiment of the present invention, UE, which judges to whether there is in the corresponding time span of CDRX mode duration information, to be needed
The process for the data service to be performed is：According to the operating parameter of UE, holding for each single item data service that UE needs to perform is determined
At the start of line moment, if judging, definite any one execution initial time does not fall within the CDRX mode duration information in acquisition
In corresponding time span, then judge that UE need not be held in the corresponding time span of CDRX mode duration information of acquisition
Row arbitrary data business.Wherein, when this data service of UE（Such as the first data service）After being finished, that is, obtain CDRX and continue
Temporal information（Such as temporal information is 120 seconds）, i.e. the corresponding duration information of CDRX timers is 120 seconds, in this 120 seconds,
The data service next time performed in the presence of needs（Such as the second data service）, after data service next time reaches, CDRX timings
Device is reset（Timing is not continued to）, UE performs second data service, after the second data service is finished, reacquires
CDRX mode duration information（I.e. 120 seconds）, i.e. after each data services of UE are finished, network side can issue for UE again
CDRX Duration Informations.Therefore, in the embodiment of the present invention, time length corresponding in CDRX mode duration information is only ensured
Do not include any one execution initial time in degree, that is, represent in the corresponding time span of CDRX mode duration information not
Need to perform arbitrary data business.
In the embodiment of the present invention, UE is judged in the corresponding time span of CDRX mode duration information with the presence or absence of at least
One data service for needing to perform, if being not present, RRC chain ruptures request is sent from UE to network side, and based on network side
Chain rupture is allowed to instruct, disconnection is connected with the RRC of network side；Otherwise, UE is determined whether to determine the operation of subsequent execution.
When UE judges that the execution initial time that there is at least one data service is corresponded in CDRX mode durations information
Time span in when, UE perform determine whether, be specially：From the execution initial time of at least one of above-mentioned data service
In, obtain with current time immediate execution initial time, and obtain current time and the acquisition execution initial time it
Between time difference, which is that finish time and the data service next time of currently performed data service performs starting
Duration between moment, as shown in fig.5, after the n-th data service of UE is finished（After being waken up by n-th）, net
Network stresses newly to issue CDRX mode duration information to UE, if being finished from first time data service to n-th data industry
Business is finished, and the corresponding time span of CDRX mode duration information is without resetting, then the n-th data industry
The corresponding time span of CDRX mode duration information that business obtains after being finished, holds with any data service before
The corresponding time span all same of CDRX mode duration information obtained after row, is t；According to the time difference, often
A CDRX pattern cycles duration, the energy consumption of each CDRX pattern cycles, obtains the corresponding CDRX when locally keeping CDRX patterns
Pattern energy consumption；According to the above-mentioned time difference, the energy consumption of RRC connections is established, disconnects the energy consumption of RRC connections, during each DRX mode cycle
Long, the energy consumption in each DRX mode cycle, obtains corresponding DRX mode energy when locally by CDRX pattern switchings to DRX mode
Consumption, wherein, after UE, which is disconnected, to be connected with the RRC of network side, which is in DRX mode.
Specifically, above-mentioned CDRX patterns energy consumption can use the following formula to obtain：
POWER_CDRX_Hold=(T/CDRX_CYCLE_T)*Power_CDRX
Wherein, POWER_CDRX_Hold is CDRX pattern energy consumptions；When T is current time and the execution starting of above-mentioned acquisition
Time difference between quarter；CDRX_CYCLE_T is each CDRX pattern cycles duration；Power_CDRX is each CDRX patterns week
The energy consumption of phase, the value can be obtained by testing, such as the energy consumption of each CDRX pattern cycles of above-mentioned UE taken multiple measurements
Afterwards, the average value repeatedly measured is calculated to obtain.
As shown in fig.5, if UE switches without state, that is, CDRX patterns are kept, since UE and network side are constantly in
RRC connection status, when the execution initial time of above-mentioned next data service for needing to perform reaches, performs the data service
, without the process established UE and be connected with network side RRC.
In addition, above-mentioned DRX mode energy consumption can use the following formula to obtain：
POWER_DRX_Hold=POWER_CDRX_RRC_OFF+POWER_CDRX_RRC_ON+(T/DRX_CYCLE_T)*
Power_DRX
Wherein, POWER_DRX_Hold is DRX mode energy consumption；POWER_CDRX_RRC_OFF is the energy for disconnecting RRC connections
Consumption；POWER_CDRX_RRC_ON is the energy consumption for establishing RRC connections；T be current time and above-mentioned acquisition execution initial time it
Between time difference；DRX_CYCLE_T is DRX mode cycle duration；Power_DRX be each DRX mode cycle energy consumption, the value
It can be obtained by testing, after such as being taken multiple measurements to the energy consumption in each DRX mode cycle of above-mentioned UE, calculate the multiple survey
The average value of amount obtains.
As shown in fig.5, include at least one data industry when the corresponding time span of CDRX mode duration information is interior
During the execution initial time of business, if after the currently performed data services of UE, i.e., by CDRX pattern switchings to DRX mode, then
The RRC connections of disconnection UE and network side are needed, at this time, it may be necessary to consume " energy consumption for disconnecting RRC connections ", and work as above-mentioned next need
, it is necessary to re-establish the RRC connections of UE and network side when the execution initial time for the data service to be performed reaches, need at this time
Consume " energy consumption for establishing RRC connections ".Therefore, when UE needs what is performed by CDRX pattern switchings to DRX mode up to next
The execution initial time of data service reaches, and UE needs " to disconnect RRC and connect-keep the above-mentioned next needs of DRX mode-wait
The execution initial time of the data service of execution establishes RRC connections when reaching ", establish i.e. executable above-mentioned next after RRC connections
A data service for needing to perform.
Based on the above process, more above-mentioned CDRX patterns energy consumption and DRX mode energy consumption, and according to comparative result, to UE with
RRC connection relations between network side are handled, and are specially：When judgement CDRX patterns energy consumption is more than DRX mode energy consumption（I.e.
POWER_CDRX_Hold>POWER_DRX_Hold）When, UE sends RRC chain ruptures request to network side, and is fed back according to network side
Permission chain rupture instruction, disconnection be connected with the RRC of network side；When judgement CDRX patterns energy consumption is less than DRX mode energy consumption（I.e.
POWER_CDRX_Hold<POWER_DRX_Hold）When, UE keeps being connected with the RRC of network side.
