Embodiment 2

The embodiment of the invention provides a kind of method of base station energy-saving, and the embodiment of the invention is an example with WCDMA (WidebandCode Division Multiple Access) system, specifies the method for base station energy-saving; In the WCDMA system, the base station energy-saving control appliance is RNC (Radio Network Controller, a radio network controller), and the base station energy-saving actuating equipment is that as shown in Figure 5, this method comprises NodeB (Node Base station, base station):

501, the loading condition of RNC detected cells if detecting the sub-district that is in normal operating conditions satisfies the sub-district energy saving condition, judges that then need close described sub-district realizes the energy-conservation of base station, and then execution in step 502.

Wherein, any combination in any one or the following condition of described sub-district energy saving condition in the following condition: the load of described sub-district is lower than first load-threshold that pre-sets; Number of users is lower than the number of users thresholding that pre-sets in the perhaps described sub-district; Perhaps described sub-district arrives closes pre-seting the time of sub-district; Perhaps the load of described sub-district is compared with the load of coverage cell with alien frequencies and is lower than the load difference thresholding that pre-sets; The quantity of subscriber equipment is compared with the quantity of subscriber equipment in the coverage cell with alien frequencies and is lower than the quantity difference threshold that pre-sets in the perhaps described sub-district.

502, the RNC Indication message that will close the sub-district sends to NodeB, comprises the adjustment step-length of adjusting the P-CPICH transmitting power in the described Indication message and/or adjusts the time interval.Wherein, if detect a sub-district of satisfying the sub-district energy saving condition, just send the Indication message of closing a described sub-district in the embodiment of the invention to described NodeB; If detect a plurality of sub-districts of satisfying the sub-district energy saving condition, then one by one to the Indication message of closing sub-district of described NodeB transmission corresponding to described sub-district.

Wherein, it will be understood by those skilled in the art that, be not limited in the described Indication message and comprise the adjustment time interval of adjusting the P-CPICH transmitting power and/or adjust step-length, can also be including, but not limited to adjusting number of times, wherein, if comprise in the described Indication message when transmitting power of adjusting P-CPICH is adjusted number of times, after described NodeB receives described Indication message of closing the sub-district, according to current network condition, obtain the unit of adjustment of the transmitting power of adjusting sub-district P-CPICH and adjust the time interval, and, the transmitting power of described sub-district master P-CPICH is reduced corresponding number of times according to the adjustment number of times in the described Indication message.The embodiment of the invention is the adjustment that example specifies described sub-district P-CPICH transmitting power to comprise the adjustment step-length of adjusting the P-CPICH transmitting power in the described Indication message and to adjust the time interval.In the wherein said Indication message can but be not limited to and be carried at the cell re-configuration that sends to described NodeB and put in the request message.

Wherein, because at present in the agreement, the power of some down channels is that the transmitting power with P-CPICH serves as with reference in case adjusted the transmitting power of P-CPICH, NodeB will adjust all channel powers relevant with P-CPICH, may cause other conversation loss in the sub-district like this, therefore in closing the Indication message of sub-district, can further include the indication of the transmitting power of the P-CPICH that only adjusts described sub-district, so that described NodeB does not adjust the transmitting power of other down channels in the transmitting power of adjusting described sub-district P-CPICH according to described indication.

What it will be appreciated by those skilled in the art that is, NodeB also can and adjust the time interval according to the adjustment step-length of the transmitting power of the adjustment P-CPICH in the described Indication message, judges the transmitting power of not adjusting other down channels in the transmitting power of adjusting sub-district P-CPICH.

503, after NodeB receives the indication information of closing the sub-district that RNC sends, with the adjustment time interval in the described Indication message be the cycle, be unit with the adjustment step-length in the described message, reduce the transmitting power of described sub-district P-CPICH.

Wherein, in described Indication message of closing the sub-district, comprise the indication of only adjusting described sub-district P-CPICH transmitting power, described NodeB is the cycle with the adjustment time interval in the described Indication message, with the adjustment step-length in the described message is unit, adjust the transmitting power of described sub-district P-CPICH, other channel transmitting power are constant; When the transmitting power of the P-CPICH of described sub-district was adjusted to the predetermined electric power thresholding, NodeB closed or adjusts other channel transmitting power more automatically; To reach the purpose of further saving base station energy consumption.

504, after the transmitting power of described sub-district P-CPICH is reduced to the predetermined electric power thresholding, described NodeB sends to RNC and closes the completed message in sub-district; Described default power threshold is an empirical value, is criterion with the target that reaches base station energy-saving; Wherein, in the energy-conservation process in sub-district, as long as reached the purpose of energy saving of going to the station to meet somebody, described RNC thinks that just described purpose of closing the sub-district realizes, close differently with known sub-district, it is all functions that stop described sub-district that known sub-district is closed, and makes described sub-district can't realize any function.Wherein, what it will be appreciated by those skilled in the art that is that described NodeB can also send described response message of closing the sub-district to described RNC at once behind the Indication message of closing the sub-district that receives the RNC transmission; Perhaps NodeB does not send the response message of closing the sub-district to described RNC behind the Indication message of closing the sub-district that receives the RNC transmission.The embodiment of the invention is finished to close behind the sub-district with described NodeB and is sent to described RNC that to close the completed message in sub-district be example, specifies the operating process of closing the sub-district.

505, described RNC receives that described NodeB sends closes the completed message in sub-district; And be power save mode with the status indicator of described sub-district, there is subscriber equipment to insert or switching etc. when preventing to be in power save mode to described sub-district in described sub-district.

Further, when detecting to be in, described RNC closes sub-district in the closed procedure or power save mode, when satisfying the condition of opening the sub-district, balance for the load that keeps each sub-district of whole network, RNC need indicate NodeB to improve the described transmitting power that is in the P-CPICH that closes sub-district in the closed procedure or power save mode, avoid more subscriber equipment to be linked into the same coverage cell of alien frequencies of described sub-district, cause the load too high of alien frequencies, alien frequencies that request inserts described sub-district is got clogged with the subscriber equipment of coverage cell and can not normally insert with coverage cell.

RNC indication NodeB improves the described process of closing sub-district in the process of sub-district or power save mode P-CPICH transmitting power that is in, and specifically as shown in Figure 6, comprising:

601, if detecting to be in, RNC closes sub-district in the closed procedure or power save mode, satisfy the condition of opening the sub-district, the Indication message that then will open the sub-district sends to NodeB, comprises the adjustment step-length of adjusting the P-CPICH transmitting power in the described Indication message and/or adjusts the time interval; Wherein, it will be appreciated by persons skilled in the art that the adjustment time interval of adjustment P-CPI CH transmitting power included in the described Indication message and/or adjust step-length, can also be including, but not limited to adjusting number of times.Wherein, if comprise in the described Indication message when transmitting power of adjusting P-CPICH is adjusted number of times, after described NodeB receives described Indication message of closing the sub-district, according to current network condition, obtain the unit of adjustment of the transmitting power of adjusting sub-district P-CPICH and adjust the time interval, and, the transmitting power of described sub-district master P-CPI CH is reduced corresponding number of times according to the adjustment number of times in the described Indication message.The embodiment of the invention is the adjustment that example specifies described sub-district P-CPICH transmitting power to comprise the adjustment step-length of adjusting the P-CPICH transmitting power in the described Indication message and to adjust the time interval.Wherein said Indication message can but be not limited to and be carried at the cell re-configuration that sends to described NodeB and put in the request message.

Wherein, any combination in the condition of described satisfied unlatching sub-district can be in the following condition any or the following condition: the alien frequencies of described sub-district is higher than second load-threshold that pre-sets with the load of coverage cell; Perhaps the quantity of the subscriber equipment of the described sub-district of request access surpasses default quantity thresholding within a certain period of time; Perhaps arrive and open pre-seting the time of sub-district; Perhaps the load of described sub-district is compared with the load of coverage cell with alien frequencies and is higher than the load difference thresholding that pre-sets; The quantity of subscriber equipment is compared with the quantity of subscriber equipment in the coverage cell with alien frequencies and is higher than the quantity difference threshold that pre-sets in the perhaps described sub-district.

602, after NodeB receives the Indication message of described unlatching sub-district, with the adjustment time interval in the described Indication message be the cycle, be unit with the adjustment step-length in the described message, improve the transmitting power of described sub-district P-CPICH.

603, during the transmitting power when the transmitting power of described sub-district P-CPICH is brought up to the sub-district normal operating conditions, described NodeB will open the completed message in sub-district and send to RNC.Wherein, what it will be appreciated by those skilled in the art that is that described NodeB can also send the response message of described unlatching sub-district at once to described RNC behind the Indication message of the unlatching sub-district that receives the RNC transmission; Perhaps described NodeB does not send the response message of described unlatching sub-district to described RNC.The embodiment of the invention is finished to open behind the sub-district with described NodeB and is sent to described RNC that to open the completed message in sub-district be example, specifies the operating process of opening the sub-district.

604, RNC receives the completed message in unlatching sub-district that described NodeB sends, and is normal operating conditions with the status indicator of described sub-district.

Further, when RNC control NodeB reduced or improve the transmitting power of sub-district P-CPICH, dividing into groups in the sub-district that needs can be closed or divides into groups in the sub-district that will need to open, and every group more than a sub-district.When the Indication message of sub-district is closed or is opened in the NodeB transmission, the sign that comprises each sub-district in the described grouping in the described Indication message, and the adjustment step-length of progressively adjusting P-CPICH transmitting power corresponding and/or the adjustment time interval with the sub-district, so that NodeB according to the sign of described sub-district, adjusts the transmitting power of described respective cell P-CPICH according to the adjustment step-length of progressively adjusting the P-CPICH transmitting power corresponding with described sub-district and/or the adjustment time interval.

Further, NodeB closes or opens in the process of sub-district in RNC control, if RNC judges that according to current network state needs stop closing the sub-district or stop the unlatching sub-district, the invention provides corresponding termination and close the sub-district or stop opening the sub-district method.Wherein, stop closing the sub-district method specific implementation as shown in Figure 7, comprising:

701, if RNC is in the sub-district of closing in the process of sub-district as if detecting, the condition of sub-district is closed in satisfied termination, and the Indication message of then termination being closed the sub-district sends to NodeB.

Wherein, described satisfied termination close that the condition of sub-district can be in the following condition any one or following condition in any combination: request inserts and is in the number of users that closes the sub-district in the closed procedure and reaches the predetermined number thresholding within a certain period of time; Perhaps be in the alien frequencies that closes the sub-district in the closed procedure and be higher than default second load-threshold with the load of coverage cell; Perhaps being in the conversation loss that closes the sub-district in the closed procedure increases.

702, after described NodeB received that the Indication message of sub-district is closed in termination that RNC sends, the described sub-district of phase down promptly stopped to reduce the transmitting power of described sub-district P-CPICH.

703, after stopping the process of closing described sub-district, NodeB, and in described message, can comprise the transmitting power of the present P-CPI CH in described sub-district, so that inform the transmitting power of the described current P-CPICH in sub-district of RNC.Wherein, what it will be appreciated by those skilled in the art that is that described NodeB can also send the response message of described unlatching sub-district at once to described RNC after the Indication message of sub-district is closed in the termination that receives the RNC transmission; Perhaps described NodeB does not send the response message that the sub-district is opened in described termination to described RNC.The embodiment of the invention stops opening behind the sub-district with described NodeB and sends to described RNC that to open the completed message in sub-district be example, specifies and stops the operating process that the sub-district is closed.
