First embodiment

Fig. 3 shows a kind of flow chart of the control method for carrier aggregation that first embodiment of the invention is provided.This implementation The control method for the carrier aggregation that example is provided is applied to terminal device 100, and the terminal device 100 is in CA patterns.Refer to Fig. 3, methods described includes：

Step S101, obtains the information about power of terminal device；

In the present embodiment, information about power can be the dump energy of battery.Battery management module in terminal device 100 The dump energy of 110 pairs of batteries is detected in real time, therefore, it can directly carry out data interaction with battery management module, from electricity Pond management module obtains the dump energy of battery.Or, dump energy can also be by calling behaviour used in terminal device 100 Make the API (Application Programming Interface, application programming interface) of system offer to obtain.

Specifically, the dump energy of battery can be searched by custom communication interfaces in the modem sides of terminal device 100. Such as, when terminal device 100 is in running order, (high-pass platform AP and modem is special by qmi by the modem of terminal device 100 Communication interface) check the battery that AP (Application Processor, application chip) side of terminal device 100 is provided Dump energy.

Step S102, the terminal device is controlled according to the CA mode of operations of the terminal device and the information about power Close at least one of up CA or descending CA.

In the present embodiment, the CA mode of operations of terminal device 100 can be to only operate in descending CA mode of operations, or, Can also be for while being operated in up CA and descending CA mode of operation.Therefore, above-mentioned steps S102 embodiment can Think：When terminal device 100 only operates in descending CA patterns, descending CA is closed according to information about power control terminal equipment 100. Or, above-mentioned steps S102 embodiment can also be：When terminal device 100 is in up CA and descending CA works simultaneously During the pattern of work, up CA is closed according to information about power control terminal equipment 100, or simultaneously close off up CA and descending CA.

Specifically, when information about power is the dump energy of battery, being closed according to information about power control terminal equipment 100 up CA, or simultaneously close off up CA and descending CA embodiment and can be：Judge whether dump energy is less than default electricity threshold Value, if dump energy is less than default power threshold,

Up CA is closed, or simultaneously closes off up CA and descending CA, if dump energy is higher than default power threshold, is protected CA mode of operations are held, step S101 and step S102 is repeated.

Power threshold can be arranged as required to, and can be stored in advance in terminal device 100.In one kind of the present embodiment Preferably in embodiment, power threshold can pre-set a default initial values, and user can lead to according to the need for itself Cross the modification power threshold such as input block such as touch-screen or keyboard., can for the terminal device 100 of variety classes or different brands To set different default initial values.

It is understood that when terminal device 100 is the mobile terminals such as smart mobile phone or tablet personal computer,

Mobile terminal in itself may be there is also the alarm threshold value of an electricity, when the electricity of terminal device 100 is to be equal to or low Electricity early warning can be carried out when the alarm threshold value such as to show red light, flashing indicator light or show electricity warning information, carried Awake user's not enough power supply, notes charging.Power threshold in this step could be arranged to identical with above-mentioned alarm threshold value, also may be used It is different from above-mentioned alarm threshold value to be set to.

For example, when the power threshold of terminal device 100 is identical with above-mentioned alarm threshold value, and when being disposed as 15%, when obtaining When the battery dump energy got is less than 15%, up CA is closed, or simultaneously closes off up CA and descending CA, to ensure that terminal is set Standby 100 cruising time.

It should be noted that close up CA according to information about power control terminal equipment 100, or simultaneously close off up CA and Descending CA embodiment can also use other modes as needed in addition to aforesaid way.For example, can set as needed Two power thresholds, including first threshold and Second Threshold are put, first threshold is more than Second Threshold, when dump energy is more than second Threshold value and less than first threshold when, control terminal equipment 100 closes up CA, when dump energy be less than Second Threshold when, control Terminal device 100 is closed and simultaneously closes off up CA and descending CA.

When terminal device 100 is operated in up CA, the uplink transmission power for causing terminal device 100 is increased, directly Increase the power consumption of terminal device 100 on hardware level, and cause the heating of terminal device 100, bring bad Consumer's Experience.Cause This, when closing the up CA of above-mentioned terminal device 100, the transmitting uplink data of terminal device 100 is operated in single carrier mode, can With the power consumption for reducing uplink transmission power, reducing terminal device 100, alleviate the heating of terminal device 100.Now, terminal device 100 are still operated in descending CA patterns, the need for disclosure satisfy that high-speed downloads data.

In order to prove above-mentioned conclusion, inventor has done following experiment：On certain platform, terminal device 100 is passed through into cable After line connection CMW500, terminal device has been measured respectively and has been operated under the descending CA patterns of B7C 2CC up CA and 2CC and closes It is operated in after up CA under descending CA patterns and transmission power is respectively 12.32dbm and 15dbm related data.The correlation Data are specifically included：Transmission power, up modulation system, bandwidth, theoretical uploading speed and average operating current, such as the institute of table 1 Show.

The terminal device of table 1 is operated in the data comparison table under different CA patterns

As it can be seen from table 1 after up CA is closed, the transmission power reduction of terminal device 100, uploading speed reduction, Meanwhile, average operating current is significantly reduced, and shows that uplink transmission power can be reduced, reduce terminal device by closing up CA 100 power consumption, so as to be conducive to increasing the cruising time of terminal device 100 and reduce the temperature rise of terminal device 100.

Further, since up CA depends on descending CA, accordingly it is also possible to simultaneously close off up CA and descending CA.Now, eventually The transmitting uplink data and downlink data transmission of end equipment 100 are operated in single carrier mode, by reducing terminal device 100 Data are uploaded and downloading data, to increase the cruising time of the terminal device 100.

Further, as shown in figure 4, when terminal device 100 simultaneously be operated in up CA and descending CA mode of operation and When information about power is the dump energy of terminal device 100, if having performed above-mentioned steps S102 closes up CA, or simultaneously close off After up CA and descending CA, methods described can also comprise the following steps S103.

Step S103, if detecting the dump energy greater than or equal to default power threshold, opens what is closed CA。

When user charges to terminal device 100 so that the electricity of terminal device 100, which is met, to be required, cruising time energy It is enough ensure in the case of, it is contemplated that user is to that the need for the data transmission bauds of terminal device 100, can open in step S102 The CA closed.If specifically, closing up CA in step S102, step S103 is：If detecting the dump energy Greater than or equal to default power threshold, then the up CA closed is opened.If simultaneously closed off in step S102 up CA and Descending CA, then step S103 be：If detecting the dump energy greater than or equal to default power threshold, unlatching is closed Up CA and descending CA.In this step, power threshold can be with setting in above-mentioned steps S102 embodiment Power threshold is identical, can also be different, can specifically be arranged as required to.

Compared to prior art, the control method of carrier aggregation provided in an embodiment of the present invention can not set in terminal Increase up CA in user interface on standby 100 and beat opening/closing button and in the case that descending CA beats opening/closing button, pass through Intelligentized control method is carried out to the CA of terminal device 100, the cruising time of terminal device 100 is effectively improved.

Second embodiment

Fig. 5 shows a kind of flow chart of the control method for carrier aggregation that second embodiment of the invention is provided.This implementation The control method for the carrier aggregation that example is provided is applied to terminal device 100, and the terminal device 100 is in up CA and descending CA The pattern worked simultaneously.Referring to Fig. 5, methods described includes：

Step S202, judges whether the dump energy is less than default power threshold；

When the dump energy of the battery accessed by step S201 is less than default power threshold, show the residue electricity of battery Amount is relatively low, now thinks that the dump energy can not meet demand of the user to the cruising time of terminal device 100, in order to increase end In the cruising time of end equipment 100, perform step S204.

When the dump energy of the battery accessed by step S201 is greater than or equal to default power threshold, show battery Dump energy is more sufficient, now thinks that the dump energy can meet demand of the user to the cruising time of terminal device 100. Now, it is contemplated that influence of the temperature of terminal device 100 to Consumer's Experience sense, step S204 can be continued executing with.

Step S203, closes up CA, or simultaneously close off up CA and descending CA；

In the present embodiment, step S201 to step S203 embodiment are referred in above-mentioned first embodiment Step S101 and step S102, here is omitted.

Step S204, judges whether the crystal oscillator temperature of the terminal device is higher than default temperature threshold；

Crystal oscillator temperature is to influence the key factor of the temperature of terminal device 100.When terminal device 100 is operated in up CA simultaneously During with descending CA patterns, when being especially operated in up CA patterns, the increase of the uplink transmission power of terminal device 100 will be caused, So as to directly increase the power consumption of terminal device 100 on hardware level, the rising of crystal oscillator operating temperature can be so directly resulted in.Cause This, in the present embodiment, using crystal oscillator temperature as whether close a terminal equipment 100 CA evaluation factor.

Certainly, it is necessary to first obtain the crystal oscillator temperature of terminal device 100 before S204 when performing step.Obtain terminal device The embodiment of 100 crystal oscillator temperature has a variety of.For example, in a particular application, passing through the temperature sensor set close to crystal oscillator 112 such as thermistors are detected in real time to the operating temperature of the crystal oscillator of terminal device 100.At this point it is possible to pass through processor 106 Data interaction is carried out with temperature sensor 112, the temperature value for reading the output of temperature sensor 112 is used as crystal oscillator temperature to be determined Degree.In addition, terminal device 100 is also provided with an application program, memory 102 is stored in, is called by processor 106, is used In the crystal oscillator temperature and optimization processing that obtain the collection of temperature sensor 112.It therefore, it can by used in terminal device 100 The API (Application Programming Interface, application programming interface) that operating system is provided is come on calling Application program is stated, to obtain crystal oscillator temperature.It should be noted that due to the reading accuracy and thermistor and crystalline substance of thermistor The distance between shake, cause that there is deviation between the actual work temperature of the crystal oscillator temperature and crystal oscillator read.Therefore, in order to carry The accuracy of high judged result, in the preferred scheme of the present embodiment, accessed crystal oscillator temperature is after temperature-compensating Crystal oscillator temperature.

In step S204, temperature threshold can feed back according to the hardware configuration and Consumer's Experience of terminal device 100 to be set. If acquired crystal oscillator temperature is higher than the temperature threshold, step S203 is performed.By closing up CA, or simultaneously close off up CA and descending CA, reduces uplink transmission power, reduces the power consumption of terminal device 100, reduces crystal oscillator temperature, is conducive to improving user Experience, while being also beneficial to increase the service life of crystal oscillator, that is, increases the life-span of terminal device 100.

If crystal oscillator temperature is less than or equal to temperature threshold, it is considered that the crystal oscillator temperature of present terminal equipment 100 will not Consumer's Experience is influenceed, now terminates, when time judgement, into judging next time, to repeat above-mentioned steps S201 to step S204.

It should be noted that after execution of step S203, when user charges to terminal device 100 so that detection The battery dump energy of the terminal device 100 arrived is greater than or equal to above-mentioned power threshold so that the cruising time of terminal device 100 Can be ensured, and the terminal device 100 detected crystal oscillator temperature be less than or equal to said temperature threshold value when, it is contemplated that User is to that the need for the data transmission bauds of terminal device 100, can open the CA closed in step S203.If specifically, Up CA is closed in step S203, then opens the up CA closed.If having simultaneously closed off up CA in step S203 with Row CA, then open the up CA and descending CA closed.

The present embodiment adds the judgement to crystal oscillator temperature, by terminal device 100 simultaneously on the basis of first embodiment Whether battery dump energy and crystal oscillator temperature are as closing a terminal equipment 100 when being operated under up CA and descending CA patterns CA evaluation factor, is conducive on the basis of the cruising time of terminal device 100 is ensured, it is to avoid the bonnet of terminal device 100 Temperature is too high, influences the experience sense of user.

3rd embodiment

Fig. 6 shows a kind of flow chart of the control method for carrier aggregation that third embodiment of the invention is provided.This implementation The control method for the carrier aggregation that example is provided is applied to terminal device 100, and the terminal device 100 is in up CA and descending CA The pattern worked simultaneously.Referring to Fig. 6, methods described includes：

Step S301, obtains the dump energy of the battery of terminal device；

Step S302, judges whether the dump energy is less than default power threshold；

If the dump energy is less than default power threshold, step S303 is performed, if the dump energy is higher than or waited In default power threshold, step S304 is performed.

Step S303, closes up CA, or simultaneously close off up CA and descending CA；

In the present embodiment, step S301 to step S303 embodiment are referred in above-mentioned first embodiment Step S101 and step S102, here is omitted.

Step S304, judges whether the received signal strength of the descending CA is less than default signal strength threshold；

In the present embodiment, the intensity for receiving signal can be obtained by the value for the interface RSRP for checking antenna, for example, RSRP Rx [0]=- 65dBm.

Wherein, signal strength threshold can be stored in advance in terminal device 100, can also be inputted by input block. Specifically, signal strength threshold can rule of thumb and real needs set.For example, could be arranged in the present embodiment- 125dbm。

If the received signal strength is less than the signal strength threshold, step S305 is performed；If the reception signal is strong Degree is more than or equal to the signal strength threshold, then terminates, when time judgement, into judging next time, to repeat above-mentioned steps S301 to step S305.

Step S305, closes the up CA.

It should be noted that, it is necessary to first obtain descending CA received signal strength before performing step S304.It can manage Solution, terminal device 100 is when entering row data communication, the relevant communication parameter that can be recorded, can be in the messaging parameter recorded Search received signal strength when terminal device 100 is operated in descending CA.For example, when the terminal device 100, to be operated in 2CC descending During the up CA of CA and 2CC, the received signal strength of two member carriers is respectively RSRP1 and RSRP2, and inventor sends out through research It is existing, when the received signal strength sum of two member carriers is less than above-mentioned signal strength threshold, the descending letter of terminal device 100 It is number bad.Because up CA also needs to depend on descending CA, in the case of descending CA dtr signals, up CA is remote The demand normally used can not be met, therefore, now, up CA, which is opened, also can not realize the high-speed uploading of data.Cause This, now can be by closing up CA, to increase the cruising time of terminal device 100 and reduce the temperature rise of terminal device 100.

Further, after execution of step S303 or S305, when user charges to terminal device 100 so that inspection The battery dump energy of the terminal device 100 measured is greater than or equal to above-mentioned power threshold so that during the continuation of the journey of terminal device 100 Between can be ensured, and the terminal device 100 detected received signal strength be higher than signal strength threshold when, it is contemplated that User is to that the need for the data transmission bauds of terminal device 100, can open the CA closed in step S303 or S305.Specifically , up CA is closed, then opens the up CA closed, if closing up CA and descending CA, it is upper that unlatching is closed Row CA and descending CA.

The present embodiment adds the judgement to received signal strength on the basis of first embodiment, by terminal device 100 Whether battery dump energy and received signal strength are used as and close a terminal when being operated under up CA and descending CA patterns simultaneously The CA of equipment 100 evaluation factor, is conducive to increasing the cruising time of terminal device 100 and reduces the temperature rise of terminal device 100.

Step S402, judges whether the dump energy is less than default power threshold；

If the dump energy is less than default power threshold, step S403 is performed, if the dump energy is higher than or waited In default power threshold, step S404 is performed.

Step S403, closes up CA, or simultaneously close off up CA and descending CA；

In the present embodiment, step S401 to step S403 embodiment correspondingly can be implemented with reference to above-mentioned first Step S101 and step S102 in example, here is omitted.

Step S404, obtains the transmission power of the corresponding main plots of the up CA as the first transmission power, obtains institute The transmission power of the corresponding secondary cells of up CA is stated as the second transmission power；

The acquisition modes of the transmission power of the corresponding main plot of up CA and the transmission power of the corresponding secondary cells of up CA Can be：Directly search the Initial Trans for being pre-stored within terminal device 100.But, it is contemplated that when terminal device 100 is During mobile terminal, the transmission power that the transmission power and the corresponding secondary cells of up CA that the corresponding main plot of up CA needs need Changed different from the distance of base station with mobile terminal.Therefore, more accurately controlled to realize, in step S404 The transmission power of the corresponding main plots of up CA obtained and the preferred embodiment of transmission power of the corresponding secondary cells of up CA are： Real-time searching terminal device 100 is according to the Initial Trans of the corresponding main plots of up CA, the corresponding secondary cells of up CA The distance between Initial Trans and terminal device 100 and base station calculate obtained transmission power.For example, for being operated in The terminal device 100 of the descending CA patterns of 2CC up CA and 2CC, Active Carrier 0 represent main plot, Active Carrier 1 represents secondary cell, by checking that Active Carrier 0 and Active Carrier 1 tx power values can To obtain the transmission power that the transmission power and secondary cell of main plot needs need.For example, the transmission power that main plot needs is 5dbm, the transmission power that secondary cell needs is 6dbm.

Step S405, judges whether first transmission power is more than default power with the second transmission power sum Threshold value；

Wherein, power threshold can rule of thumb be set, and can be pre-stored within terminal device 100, can be by defeated Enter unit and change the power threshold.For example, could be arranged to 15dbm in the present embodiment.
