If the first base station does not receive any cooperation request message within a cooperation cycle, can carry out flow process as shown in Figure 4:
The state of oneself is confirmed in S401, the first base station, if the first base station is current, is not set to dominant base or from base station, proceeds to S402.
Further, if the first base station is current, has been configured to dominant base or from base station, has continued to keep current state.
S402, judge that whether the customer charge of the first base station than is less than Second Threshold, if the customer charge of the first base station ratio is less than Second Threshold, proceeds to S403; If the customer charge of the first base station ratio is not less than (being more than or equal to) Second Threshold, proceed to S409.
Wherein, the customer charge of the first base station is than the ratio that is the user's that accessed of the first base station quantity and the user's that the first base station allows access maximum quantity; Second Threshold is equal to or less than first threshold, and for example Second Threshold can be set to threshold T 2, T1<=T2.
S403, the first base station, the first base station are set to dominant base, proceed to S404.
The Reference Signal Received Power that S404, the first base station report according to the adjacent cell base station of the first base station (Reference Signal Receiving Power is called for short RSRP), selects RSRP higher than the adjacent cell base station of the 3rd threshold value, proceeds to S405.
Wherein, the grade of the value of the 3rd threshold value and base station self signal coverage strength is relevant.
S405, the first base station to select RSRP higher than the 3rd threshold value adjacent cell base station send cooperation request message, proceed to S406.
S406, the first base station receive the cooperation response message of the adjacent cell base station transmission of the first base station, the information of the collaboration user of the adjacent cell base station that comprises the first base station in this cooperation response message, for example the cooperate ID of collaboration user of the adjacent cell base station that comprises the first base station in response message, proceeds to S407.
Further, if the first base station does not receive the cooperation request failure that the cooperation response message that the adjacent cell base station of the first base station sends or the adjacent cell base station that receives the first base station send, can from remaining adjacent cell measuring value, choose same number of RSRP higher than the adjacent cell base station of the 3rd threshold value, again initiate cooperation request message.For example, the first base station that is set to dominant base sends cooperation request message to 3 RSRP higher than the 3rd threshold value from base station, only receive that 2 RSRP are higher than the cooperation response message sending from base station of the 3rd threshold value, the first base station sends cooperation assignment messages to these 2 RSRP higher than the 3rd threshold value from base station; Also has another situation, the first base station that is set to dominant base sends cooperation request message to 3 RSRP higher than the 3rd threshold value from base station, only receive that 2 RSRP are higher than the cooperation response message sending from base station of the 3rd threshold value, the first base station from remaining RSRP higher than selecting again 1 base station to send cooperation request message the 3rd threshold value adjacent cell base station, when receive 3 RSRP higher than the 3rd threshold value from base station, send cooperation response message time, just to these 3 RSRP, higher than the 3rd threshold value, from base station, send cooperation assignment messages; If the first base station has traveled through remaining RSRP higher than in the 3rd threshold value adjacent cell base station, still do not receive that 3 RSRP are higher than the cooperation response message sending from base station of the 3rd threshold value, the first base station only sends cooperation assignment messages to the base station that sends cooperation response.
The cooperation response response message that S407, the first base station send according to the adjacent cell base station of the first base station receiving sends cooperation assignment messages to the adjacent cell base station of the first base station, in this cooperation assignment messages, comprise Secondary resource and distribute indication information, the resource that the collaboration user that Secondary resource distributes indication information to indicate the adjacent cell base station that is the first base station and the first base station distributes, proceeds to S408.
Wherein, Secondary resource distributes indication information can comprise the ID of the first base station self collaboration user and the running time-frequency resource that the adjacent cell base station collaboration user of the first base station collaboration user and the first base station is distributed.
It is relative users Resources allocation that indication information is distributed according to resource in S408, the first base station.
The state of S409, the first base station is set to from base station state or intercepts state.
In above-mentioned flow process, the execution sequence of step 401, step 402 can exchange.
Further, be set to the first base station of dominant base and can be according to the cooperation cycle to the first base station, from base station, send cooperation request message.
By the embodiment of the present invention four, if base station within a cooperation cycle in the state of intercepting and do not receive any cooperation request message, by the further value that judges the customer charge ratio of base station self, check whether the duty ratio of base station itself surpasses system to the resource upper limit of base station assigns, when the customer charge of base station self than surpass system to the resource of base station assigns in limited time, this base station no longer participates in base station collaboration set, by distributing to the resource of collaboration user use, carry out certain restriction, thereby can guarantee the current user's who has accessed in base station performance, when the customer charge of base station self than do not surpass system to the resource of base station assigns in limited time, oneself is set to dominant base.By oneself, be set to dominant base, can higher than the adjacent cell base station of the 3rd threshold value, send cooperation request message to RSRP, receive RSRP higher than the cooperation response message of the adjacent cell base station transmission of the 3rd threshold value, according to this cooperation response message, the collaboration user of base station self and RSRP are carried out to resource distribution higher than the collaboration user of the adjacent cell base station of the 3rd threshold value, make the user in cooperation set can share running time-frequency resource, thereby the utilance of network to frequency spectrum resource can be provided.
In addition, for avoiding when the state of base station is set to dominant base, resource load to base station assigns surpasses system to the resource upper limit of the distribution of base station, can consider to carry out certain restriction to sending the number of the base station of cooperation request message, the number that for example sends the base station of cooperation request message is less than or equal to N, thereby make the number from base station of setting up cooperation relation with dominant base can not surpass N, can guarantee that the resource load of base station assigns is in certain scope.
