Embodiment
Can SAR index is related to terminal by authentication test, obtain sale qualification.And there is different standards in different countries for SAR certification, in some country, the requirement to SAR is higher, and other countries are then relatively low to the requirement of SAR.In order to be the SAR requirement adapting to country variant, the present invention proposes a kind of scheme, the operator of Dynamic Recognition country variant, requiring higher country to SAR, adopts lower transmitting power; Requiring lower country to SAR, then take higher transmitting power.Like this can when size keep competitiveness, the contradiction between coordinates transmission power and SAR, at least meets and can obtain reasonable transmitting power and TRP index in a part of country.
Technical scheme in the embodiment of the present invention is understood better in order to make those skilled in the art person, and enable the above-mentioned purpose of the embodiment of the present invention, feature and advantage become apparent more, below in conjunction with accompanying drawing, technical scheme in the embodiment of the present invention is described in further detail.
See Fig. 1, it is the method for adjustment flow chart of a kind of transmitting power of the embodiment of the present invention.
The method can comprise:
Step 101, terminal obtains the Public Land Mobile Nerwork PLMN identification information of network side.
There is multiple Virtual network operator in each country, and the network of each operator has Public Land Mobile Nerwork (Public Land Mobile Network, PLMN) identification information, is also PLMN ID.Terminal, by obtaining the PLMN ID of network side, can be known the country belonging to this operator, and then can know the requirement of this country to SAR.
The process that terminal obtains network side PLMN ID can be by web search and the system message receiving network side after starting up of terminal, and then obtains the PLMN ID in system message.Certainly also can also have other modes, such as network side informs the PLMN ID of this network side of terminal by other means.
Step 102, the transmitting power span corresponding with the PLMN identification information of described network side is searched in PLMN database, the corresponding relation of PLMN identification information and transmitting power span is stored in described PLMN database, wherein, the transmitting power span corresponding to PLMN identification information of described network side meets the SAR requirement of network side.
First, obtain the PLMN ID of the carrier network of multiple country, then according to the requirement of the SAR of every country, determine the transmitting power span meeting SAR and require, finally set up the PLMN ID of Duo Zu various countries carrier network and meet the corresponding relation of the transmitting power span that SAR requires, and will the PLMN database of above-mentioned corresponding relation stored in terminal be organized more, wherein, often organize the span of a corresponding transmitting power of PLMN ID in corresponding relation, this span can be one or more concrete numerical value, also can be the higher limit etc. of transmitting power, do not limit herein, the transmitting power span that each PLMN ID is corresponding meets the SAR requirement of the network side with corresponding PLMN ID, SAR requires that the transmitting power that the PLMN ID of higher network is corresponding is less, certainly, the transmitting power that PLMN ID is corresponding can be the maximum transmission power that the SAR of the network side meeting this PLMN ID requires.
The PLMN ID of Duo Zu operator and the corresponding relation of transmitting power span is at least comprised in the PLMN database of this terminal, as shown in the table.

| PLMN ID2 | VAULE(numerical value) 2 |
Wherein, field value corresponding to transmitting power span field can be the concrete numerical value of transmitting power, also can be the grade or number range etc. of transmitting power.Certainly, the SAR that also can also comprise each PLMN ID in this PLMN database requires.
When terminal is after the PLMN ID of the network side of upper step acquisition current network side, the transmitting power span that the PLMN ID of this network side is corresponding can be searched in its PLMN database.If there is the PLMN ID of this network side in this database, then continue to perform step 103.
If there is not the PLMN ID of this network side in this database, then terminal can hang up, and sends manually-operated prompt tone, manually inputs to point out user or selects transmitting power.After the transmitting power receiving artificial input or selection, terminal can learn this transmitting power, and in its PLMN database, increase the PLMN ID of this network side and the entry of the corresponding relation of the transmitting power manually inputting or select.
Step 103, is set to meet the transmitting power span that the PLMN identification information of described network side is corresponding by the transmitting power of described terminal.
After upper step obtains transmitting power, in this step, himself transmitting power of terminal and adjustable, is set to meet the transmitting power span that the PLMN ID of the network side that upper step obtains is corresponding by transmitting power.So just when size keeps competitiveness, the transmitting power meeting SAR and require can be obtained.
The embodiment of the present invention, by the operator of Dynamic Recognition country variant, obtains the PLMN ID of carrier network, and according to the PLMN database set up in advance, requiring higher country to SAR, adopts lower transmitting power; Requiring lower country to SAR, then take higher transmitting power, thus achieve when size keeps competitiveness, the contradiction between coordinates transmission power and SAR.
