In step 520, if in base station configuration change request success in step 501 and the second base station 502 upgrades corresponding information, second base station 502 sends base station configuration change acknowledge message to the first base station 501, and this message is for confirming base station configuration change request message in step 501.
In step 521, if unsuccessful in base station configuration change request in step 501, second base station 502 sends base station configuration change failed message to the first base station 501, and it does not accept the base station configuration change request of the first base station 501 for replying the first base station 502, base station 501 second.
In yet another embodiment, figure 6 show the flow chart of CoMP initialization procedure, CoMP process of establishing comprises CoMP request and CoMP replys or CoMP failure, and wherein the first base station 601 also can be central node.
Except the scheme of the base station role configuration in Fig. 4 and Fig. 5, base station role also can be configured by CoMP initialization procedure.
In step 610, the first base station 601 sends CoMP request message to the second base station 602.
CoMP message comprises cooperation feature, this cooperation feature is used to indicate the cooperation relation of the first base station 601 and the second base station 602, this cooperation relation comprise the second base station 602 as the first base station 601 by control base station or the second base station 602 be not the first base station 601 by control base station.
When to be the second base station 602 be not the first base station 601 of the cooperation relation in cooperation feature by control base station time, coordinated multipoint transmission is carried out in the first base station 601 and the second base station 602 in a distributed manner pattern, and also namely cooperation is eliminated in the interference of minizone is distributed.
When the cooperation relation in cooperation feature is the second base station 602 as the first base station 601 by control base station, coordinated multipoint transmission is carried out in first base station 601 and the second base station 602 in a centralized pattern, wherein the first base station 601 is as control base station, namely second base station 602, as by control base station, is also also that the interference elimination cooperation of minizone is centralized.
CoMP request message also includes but not limited to following at least one item:
Type of message;
The Global base station ID of the first base station: positive integer (1 ..., 4095 ...);
The Global base station ID of the second base station: positive integer (1 ..., 4095 ...);
Registration request, it is used to indicate the multipoint cooperative starting or stop minizone;
The community reported: ECGI, 0 ... the largest cell number > of < base station;
Cooperation carrier frequency identifies: EARFCN or EARFCN expands;
Part successfully indicates: enumerate (part successfully allows ...), this instruction is only just included when part successfully allows.
In step 620, if the second base station 602 accepts the CoMP request in step 601, the second base station 602 sends CoMP and replys message to the first base station 601.
CoMP replys message and is used for confirming that CoMP asks successfully to the first base station 601, and it includes but not limited to following at least one item:
The confirmation instruction of cooperation relation;
Cooperation carrier frequency identifies.
