Embodiment
Basic thought of the present invention is: by obtaining the state information of different RNC sub-district, state information according to sub-district among this RNC, carry out the Energy Saving Control judgement of base station, and by corresponding Energy Saving Control (immediately dormant cell, friendly dormant cell, wake the sub-district up immediately, the close friend wakes the sub-district up) realization wakes up or makes it enter resting state base station cell.Here, the state information of different RNC sub-district by between the RNC that newly establishes between cell information request message and RNC the cell information response message obtain, perhaps, obtain the indication information of the state information of different RNC sub-district, thereby obtain the state information of different RNC sub-district by the existing message bearing between the RNC.The present invention will control this sub-district in the time of should entering resting state in definite sub-district and enter resting state, and more corresponding sub-district be waken up the access user, realize the energy-conservation of base station most possibly, realize simple and practical.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Embodiment one
In the present embodiment, between RNC the decision algorithm of energy-conservation control according to the current time period, the power save mode of this RNC sub-district, load condition, the power save mode of different RNC sub-district are comprehensively adjudicated; Cell information request (INTER-RNC CELL INFO REQUEST) message is carried cell information request between RNC between use RNC; Use cell information response (INTER-RNC CELL INFO RESPONSE) message between RNC, expression is handled successfully; Use cell information failure (INTER-RNC CELL INFOFAILURE) message between RNC, failure is handled in expression; Use cell information renewal (INTER-RNC CELLINFO UPDATE) message between RNC, cell information upgrades between expression RNC; Energy-conservation control indication (INTER-RNC ENERGY SAVINGS INDICATION) message is carried energy-conservation control indication between RNC between use RNC; Use energy-conservation control response (INTER-RNC ENERGY SAVINGSRESPONSE) message between RNC, expression is handled successfully; Use energy-conservation control failed message (INTER-RNCENERGY SAVINGS FAILURE) message between RNC, failure is handled in expression.Need to prove that above-mentioned message all is to be the newly-installed message body of realization technical solution of the present invention, the message format of above-mentioned message does not limit, as long as comprise above-mentioned corresponding information.
Fig. 1 is the flow chart of the energy-saving control method embodiment one of base station between RNC of the present invention, and as shown in Figure 1, the energy-saving control method of base station comprises the steps: between this example RNC
Step 101: the information of obtaining sub-district between INTER-RNC: state informations such as power save mode (whether being in power save mode) and load condition; RNC1 initiates INTER-RNC CELL INFO REQUEST message and gives RNC2, the information of sub-district between request RNC.
Step 102: if handle successfully, RNC2 returns INTER-RNC CELL INFORESPONSE message to RNC1, carries the information of the sub-district of request: state informations such as power save mode (whether being in power save mode) and load condition; If handle failure, RNC2 returns INTER-RNC CELLINFO FAILURE message to RNC1.
INTER-RNC CELLINFO UPDATE takes place to send after changing the power save mode of the sub-district of this RNC is passed to different RNCRNC2 in the power save mode of the sub-district of step 103:RNC1.
After step 104:RNC2 receives INTER-RNC CELL INFO UPDATE, upgrade the state information (power save mode of sub-district etc.) of the sub-district of preserving RNC1.
Step 105:RNC1 periodically carries out the Energy Saving Control judgement, according to the time period, and the power save mode of this RNC sub-district, the load condition of different RNC sub-district, power save mode comprehensively carries out the Energy Saving Control judgement; The condition that for example enters power save mode is: the time period sub-district of 22:00～7:00 of (1) every day enters resting state, the other times section state of resuming work; (2) different RNC cell load nonoverload; (3) different RNC sub-district is not in power save mode.When RNC1 adjudicates above-mentioned condition when all satisfying, impel the sub-district in this RNC to enter power save mode: the dormancy energy-efficient treatment of carrying out this RNC sub-district, even the dormancy of this RNC sub-district reduces to zero or turn-off carrier wave with the pilot channel power of the carrier wave of sub-district, enter power save mode.The mode of dormant cell comprises dormant cell, friendly dormant cell immediately.
Step 106:RNC1 periodically carries out the Energy Saving Control judgement, and according to current slot, the power save mode of this RNC sub-district, the load condition of different RNC sub-district, power save mode comprehensively carry out the Energy Saving Control judgement; After the RNC1 judgement reaches the condition of waking up the sub-district in this RNC, carrying out waking up of this RNC sub-district recovers to handle, as overloading, when this RNC sub-district is in resting state, then adjudicates and wake this RNC sub-district up when definite different RNC cell load identical or adjacent with this RNC cell coverage area.The pilot channel power of the carrier wave of sub-district is reverted to operation state values, and withdraw from power save mode.The mode of waking the sub-district up comprise wake the sub-district up immediately, the close friend wakes the sub-district up.
Dormancy and wake the patent document that the method REFERENCE TO RELATED people of the sub-district in this RNC has applied for up, its denomination of invention be " implementation method and a system that a kind of base station energy-saving is controlled ", application number is PCT/CN2008/002118.
Step 107:RNC1 periodically carries out the Energy Saving Control judgement, and according to current slot, the power save mode of this RNC sub-district, the load condition of different RNC sub-district and power save mode comprehensively carry out the Energy Saving Control judgement; After the RNC1 judgement need wake the sub-district of different RNC up, sub-district as this RNC is in running order, and serious excess load, and the adjacent area of different RNC is when being in power save mode, send INTER-RNCENERGY SAVINGS INDICATION message (the adjacent area id that can comprise different RNC in the message to RNC2, Energy Saving Control indication: wake the sub-district up), the sub-district that request wakes RNC2 up.Base station among the RNC2 reverts to operation state values with the pilot channel power of the carrier wave of sub-district, and withdraws from power save mode.The mode of waking the sub-district up comprise wake the sub-district up immediately, the close friend wakes the sub-district up.
Step 108:RNC2 carries out the recovery that wakes up of this RNC sub-district after receiving INTER-RNC ENERGY SAVINGS INDICATION message; If handle successfully, return INTER-RNCENERGY SAVINGS RESPONSE to RNC1; If handle failure, return INTER-RNCENERGY SAVINGS FAILURE to RNC2, can comprise failure cause in the failed message.
Embodiment two
