Embodiment 1:
The embodiment of the invention 1 provides a kind of auxiliary antenna state control method of wireless terminal.Fig. 4 is the method flow diagram of the embodiment of the invention 1.As shown in Figure 4, this method comprises:
S401, obtain the temperature of wireless terminal;
The embodiment of the invention 1 described wireless terminal for example can be for being the wireless broadband product of representative with data card (Data Card), mobile communication terminal etc.
The method of temperature of obtaining wireless terminal has multiple, including but not limited to following mode:
For example PCB temperature sensor or other temperature detecting unit can be set on wireless terminal, be used to detect the temperature value of wireless terminal, the temperature value that measures in real time to the wireless terminal feedback can adopt the periodic feedback mode then.
S402, the temperature of judging described wireless terminal and the relation between the temperature threshold upper limit and the temperature threshold lower limit;
Particularly, in S402, can compare the temperature of wireless terminal and the magnitude relationship between the temperature threshold upper limit and the temperature threshold lower limit.
S403A, when the temperature of described wireless terminal is higher than the temperature threshold upper limit, then close auxilliary antenna;
Alternatively, the detailed process of S403A also can comprise: when the temperature of described wireless terminal is higher than the temperature threshold upper limit, and state continuance very first time that the temperature of wireless terminal is higher than temperature threshold upper limit during length, close auxilliary antenna; Perhaps, when the temperature of described wireless terminal is higher than on the temperature threshold in limited time, close auxilliary antenna immediately.Wherein, when the temperature that needs wireless terminal is higher than the state continuance very first time of the temperature threshold upper limit during length, the temperature of described wireless terminal is higher than the temperature threshold upper limit: whether the temperature of judging wireless terminal maintains more than the temperature threshold upper limit in very first time length always, if think that then the temperature of wireless terminal is higher than the temperature threshold upper limit; Or whether the mean temperature of judgement wireless terminal in very first time length is above the temperature threshold upper limit, if think that then the temperature of wireless terminal is higher than the temperature threshold upper limit; Or the mode that adopts majority decision judges whether most temperature values are arranged above the temperature threshold upper limit, if think that then the temperature of wireless terminal is higher than the temperature threshold upper limit in a plurality of different temperatures values of obtaining in very first time length; Certainly, can also adopt other modes to determine that the temperature of wireless terminal is higher than the temperature threshold upper limit and lasting very first time length, does not do qualification at this.Among the embodiment after the present invention to whether being higher than the judgement of temperature threshold, similarly, follow-up repeating no more.
Wherein, the wireless terminal of the embodiment of the invention 1 has a main antenna and at least one auxilliary antenna, and main antenna is mainly used in the reception and the transmission of signal, and auxilliary antenna is mainly used in received signal usually; Auxilliary antenna can refer to the antenna and the auxiliary circuit of other performance boost except that keeping normal basic communication; second, third antenna in the MIMO pattern etc. for example; HSPA (High Speed Packet Access; high-speed packet inserts) diversity antenna in the pattern etc., promptly auxilliary antenna can be diversity antenna or the auxilliary antenna of MIMO.Usually the efficient of main antenna is higher than the efficient of auxilliary antenna, for example, can improve the MIMO effect by the first high antenna of efficient as main antenna in the MIMO pattern.
Alternatively, the auxilliary antenna of diversity antenna and MIMO can be an antenna physically, and forms different antennas by loading different software.
The default temperature threshold upper limit for example can be set to 80 ℃, also can be other value in 80 ℃～100 ℃, and the embodiment of the invention 1 is not limited to this.It will be appreciated by those skilled in the art that when the temperature of wireless terminal is higher than 80 ℃, can adopt measure that the auxilliary antenna of wireless terminal cuts out immediately, to reduce electric current or temperature; Perhaps, default very first time length can be set also, for example can be set to 30-60 second, after the temperature of wireless terminal is higher than the temperature threshold upper limit and is higher than the state continuance very first time length of the temperature threshold upper limit, the more auxilliary antenna of wireless terminal cut out; Certainly, very first time length also can be other value, and the embodiment of the invention 1 does not limit this yet.
Preferably, because the temperature signal of temperature sensor measurement or the wireless terminal tested is an analog signal, this analog signal may be interfered and produce fluctuation, and then influences the accuracy of measured value, and causes reporting wrong temperature value to cause misoperation or erroneous judgement.For avoiding this situation, the 30-60 time threshold of second can be set, whether during this period of time maintain more than 80 ℃ or 80 ℃ with the temperature of judging wireless terminal always, or the mean temperature of judging wireless terminal during this period of time is above 80 ℃, or the mode that adopts majority decision judges in a plurality of different temperatures values of obtaining in this during this period of time whether most temperature values are arranged above 80 ℃, when satisfying the condition of one of them at least, then close this auxilliary antenna.Like this, by setting default very first time length, the analog temperature value that can effectively avoid obtaining is interfered and produces fluctuation, causes erroneous judgement or misoperation.
S403B, when the temperature of described wireless terminal is lower than the temperature threshold lower limit, then open described auxilliary antenna.
Alternatively, the detailed process of S403B also can comprise: when the temperature of described wireless terminal is lower than the temperature threshold lower limit, and the temperature of wireless terminal is lower than after state continuance second time span of temperature threshold lower limit, opens described auxilliary antenna; Perhaps, when the temperature of described wireless terminal is lower than under the temperature threshold in limited time, open auxilliary antenna immediately.Wherein, when the temperature that needs wireless terminal is lower than state continuance second time span of temperature threshold lower limit, the temperature of described wireless terminal is lower than the temperature threshold lower limit: whether the temperature of judging wireless terminal maintains below the temperature threshold lower limit in very first time length always, if think that then the temperature of wireless terminal is lower than the temperature threshold lower limit; Or judge whether the mean temperature of wireless terminal is lower than the temperature threshold lower limit in very first time length, if think that then the temperature of wireless terminal is lower than the temperature threshold lower limit; Or adopt the mode of majority decision to judge in a plurality of different temperatures values of in very first time length, obtaining whether have most temperature values to be lower than the temperature threshold lower limit, if think that then the temperature of wireless terminal is lower than the temperature threshold lower limit; Certainly, can also adopt other modes to determine that the temperature of wireless terminal is lower than the temperature threshold lower limit and continues second time span, does not do qualification at this.Among the embodiment after the present invention to whether being lower than the judgement of temperature threshold, similarly, follow-up repeating no more.
Wherein, the temperature threshold lower limit for example can be 75 ℃, and its scope can be 70 ℃～85 ℃, and the second default time span can be identical or different with default very first time length, and for example, the second default time span also can be set to 30-60 second.By setting the second default time span, the analog temperature value that can effectively avoid obtaining is interfered and produces fluctuation, causes erroneous judgement or misoperation.
Fig. 5 A: diversity antenna by Fig. 5 A as can be known, open diversity antenna and will cause electric current and temperature to raise, and the switching off diversity antenna will cause electric current and temperature to reduce the exemplary plot that influences of data card power consumption in the embodiment of the invention.Fig. 5 B be in the embodiment of the invention different in flow rate to the exemplary plot that influences of data card power consumption.By Fig. 5 B as can be known, along with flow velocity increases, power consumption also increases.
In conjunction with consulting Fig. 5 A and Fig. 5 B, need to prove that please after auxilliary antenna is closed, the temperature of wireless terminal and electric current will descend, and when auxilliary antenna is performed fighting out, the temperature of wireless terminal and electric current will rise.If default temperature threshold is following just opens auxilliary antenna at once when the temperature of wireless terminal has just dropped to, then the temperature of terminal will rise to this rapidly more than the temperature threshold; If after the temperature of terminal has just surpassed default temperature threshold, just close auxilliary antenna at once, then the temperature of terminal again will be rapidly down below the near temperature threshold, so circulation will form " ping-pong ", the temperature of terminal fluctuates near temperature threshold all the time, thereby can't lower the temperature effectively and fully, auxilliary simultaneously antenna is is also opened or closed too continually, has increased the processing burden of terminal.Postpone to open auxilliary antenna behind the certain hour by setting, can effectively avoid " ping-pong ", and the temperature of wireless terminal is fully reduced, can also alleviate the processing load of terminal.
Fig. 6 is the another kind of method flow diagram of the embodiment of the invention 1.Fig. 6 at auxilliary antenna be diversity antenna, as shown in Figure 6, corresponding method flow comprises the steps:
S601, obtain the temperature of wireless terminal;
S602, the temperature of judging described wireless terminal and the relation between the temperature threshold upper limit and the temperature threshold lower limit;
S603A, be higher than the temperature threshold upper limit, the switching off diversity antenna when the temperature of described wireless terminal;
Alternatively, the detailed process of S603A also can comprise: when the temperature of described wireless terminal is higher than the temperature threshold upper limit, and state continuance very first time that the temperature of wireless terminal is higher than temperature threshold upper limit during length, the switching off diversity antenna; Perhaps, when the temperature of described wireless terminal is higher than on the temperature threshold in limited time, switching off diversity antenna immediately.
Laboratory and real net test shows, the switching off diversity antenna only can cause performance slightly to reduce (Hong Kong existing network test rate is behind some particular point switching off diversity antenna, and speed can reduce 0.3Mbps) in the special area of minority, but in most of occasion influences and uncertain; And the benefit that exchanges for is the Overall Power Consumption reduction of equipment, avoids temperature too high, and user experience obviously strengthens.
S603B, when the temperature of described wireless terminal is lower than under the temperature threshold in limited time, open described diversity antenna.
Alternatively, the detailed process of S603B also can comprise: when the temperature of described wireless terminal is lower than the temperature threshold lower limit, and the temperature of wireless terminal is lower than after state continuance second time span of temperature threshold lower limit, opens described diversity antenna; Perhaps, when the temperature of described wireless terminal is lower than under the temperature threshold in limited time, open diversity antenna immediately.
Above-mentioned handling process and flow process shown in Figure 4 are similar, do not give unnecessary details at this.
Among this clearly demarcated embodiment, the on off state of diversity antenna can be controlled by terminal, and opening of the auxilliary antenna of MIMO needs terminal and system negotiates.
Fig. 7 is the another kind of method flow diagram of the embodiment of the invention 1.Fig. 7 at auxilliary antenna be the auxilliary antenna of MIMO, as shown in Figure 7, this method comprises the steps:
S701, obtain the temperature of wireless terminal;
S702, the temperature of judging described wireless terminal and the relation between the temperature threshold upper limit and the temperature threshold lower limit;
S703A, when the temperature of described wireless terminal is higher than the temperature threshold upper limit, close the auxilliary antenna of MIMO;
Alternatively, the detailed process of S703A can comprise: when the temperature of described wireless terminal is higher than the temperature threshold upper limit, and state continuance very first time that the temperature of wireless terminal is higher than temperature threshold upper limit during length, then close the auxilliary antenna of described MIMO; Perhaps, when the temperature of described wireless terminal is higher than on the temperature threshold in limited time, close the auxilliary antenna of described MIMO immediately;
S703B, when the temperature of described wireless terminal is lower than under the temperature threshold in limited time, open the auxilliary antenna of described MIMO.
Alternatively, the detailed process of S703B can comprise: when the temperature of described wireless terminal is lower than the temperature threshold lower limit, and the temperature of wireless terminal is opened the auxilliary antenna of described MIMO when being lower than state continuance second time span of temperature threshold lower limit; Perhaps, when the temperature of described wireless terminal is lower than under the temperature threshold in limited time, allowing of obtaining immediately that the base station sends opened second of the auxilliary antenna of described MIMO and confirmed response, and confirms that according to described second response opens the auxilliary antenna of described MIMO.
Alternatively, also comprise close the step of the auxilliary antenna of described MIMO in S703A after: informing base station switches to single current with sending mode from double fluid; And first confirm that response switches to single current with receiving mode from double fluid according to what the base station was returned.
Preferably, by the unequal temperature threshold upper limit and temperature threshold lower limit are set, can effectively avoid single double fluid table tennis to switch.
Alternatively, because in the embodiment of the invention, the auxilliary antenna of diversity antenna and MIMO can form an antenna physically, and forms different antennas by loading different software, can be in conjunction with Fig. 6 and Fig. 7 for the handling process of this situation.
Above-mentioned informing base station switches to single current with double fluid; And first confirm that response switches to single current with double fluid and specifically comprises the steps: according to what the base station was returned
Particularly, above-mentioned channel quality information can also be for example RSCP, Ec/I0 etc.For example can be by RSCP, Ec/I0 etc. calculate CQI, and CQI is determined by multiple factor, such as signal to noise ratio, modulation system etc., can calculate according to the requirement of agreement, and each producer of system adopts algorithm basic identical.Different parts are: the different wireless terminal product of sensitivity, because its interference varies in size, the CQI that reports so is also different.
Step 12, revise described CQI, and revised CQI is sent to the base station, double fluid is switched to single current to indicate described base station;
For example described channel quality information CQI can be modified to less than the default double-current switch decision thresholding of list; Particularly, the default double-current switch decision thresholding of list can be stored on base station and the wireless terminal in advance, and the double-current handover operation of corresponding list be carried out according to wireless terminal channel state parameter of returning and the double-current switch decision thresholding of list that should preset in the base station.
Alternatively, it is CQI=16 that this default double-current switch decision thresholding of list can be set, and when CQI＞16, the expression signal quality is good, and the base station is supported double-current, then single current is switched to double fluid; When CQI＜16, the expression poor signal quality, single current is supported in the base station, then double fluid is switched single current.
In this step, the CQI value can be modified to CQI=15, this CQI value is less than the default double-current switch decision threshold value of list (CQI=16).
Then, revised channel status quality information (CQI=15) is sent to the base station, double fluid is switched to single current with the indication base station;
First of the single current that double fluid is switched to that step 14, the described base station of reception are returned is confirmed response;
Particularly, the base station switches to single current by more revised CQI value (CQI=15) and the default double-current switch decision threshold value of list (CQI=16) with double fluid, and returns the first affirmation response that double fluid is switched to single current to this wireless terminal.
Step 16, confirm response according to described first, switch double fluid and become single current.
In the embodiment of the invention 1, wireless terminal also sends a notification message to the base station after closing the auxilliary antenna of MIMO, and with informing base station double fluid is switched to single current, thereby make the base station can in time discharge resource, and scheduling resource reasonably, avoided the wasting of resources effectively.And, also satisfy when closing condition when the auxilliary antenna of MIMO, according to temperature value to reporting to the base station or the network channels state parameter is revised, thereby make the base station can need judge whether fill order's double fluid handover operation fast.
Alternatively, the detailed process of S703B can comprise the steps:
Alternatively, above-mentioned channel condition information can also be for example RSCP, Ec/I0, etc.
Step 22, revise described CQI, and revised CQI is sent to the base station, single current is switched to double fluid to indicate described base station;
For example described channel quality information is modified to greater than the default double-current switch decision thresholding of list;
In this step, the CQI value can be modified to CQI=17, this CQI value is greater than the default double-current switch decision threshold value of list (CQI=16).
Then revised channel quality information (CQI=17) is sent to the base station, single current is switched to double fluid with the indication base station;
The second affirmation response that step 24, the described base station of reception are returned comprises in the described second affirmation response single current is switched to double-current indication and allows to open the indication that described MIMO assists antenna;
Particularly, the base station is by more revised CQI value (CQI=17) and the default double-current switch decision threshold value of list (CQI=16), single current is switched to double fluid, and return second to this wireless terminal and confirm response, described second confirms to comprise in the response indication that single current is switched to the indication of double fluid and allows to open the auxilliary antenna of described MIMO.
Step 26, confirm response according to described second, open the auxilliary antenna of described MIMO, and single current is switched to double fluid.
In the embodiment of the invention 1, when wireless terminal need reopen the auxilliary antenna of MIMO or when single current switches to double fluid, need to obtain the permission or the agreement of base station, help management and the control of base station like this Radio Resource.
The method of the embodiment of the invention 1, by obtaining the temperature of wireless terminal, when the temperature of described wireless terminal is higher than default temperature threshold, and lasting very first time is during length, then close auxilliary antenna, thereby can prevent the overheated of wireless terminal, and prevention is by the overheated potential safety hazard that causes, for example prevent the chip overtemperature, situations such as ageing failure or short circuit burning; Guarantee that simultaneously the user can continue to use wireless terminal, the impact that during actual the use user is produced (sudden change of flow speed, fall net etc.) minimum.By setting default very first time length, the analog temperature value that can effectively avoid obtaining is interfered and produces fluctuation, thereby causes erroneous judgement or misoperation.When the temperature of described wireless terminal is lower than described default temperature threshold; then after through second time span; open described auxilliary antenna; thereby can utilize auxilliary antenna to strengthen the performance of wireless terminal; improve user experience; and wireless terminal is fully lowered the temperature, wireless end form is become overheated safeguard protection.
