It is respectively included in the configuration change request message of base station by control base station deletion information or control base station deletion message
But it is not limited to Global base station mark.
In step 520, if base station configuration change in step 501 request successfully and the second base station 502 more
New corresponding information, the second base station 502 send base station configuration change confirmation message to first base station 501, and the 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, the second base station 502 is to the
One base station 501 sends base station configuration change failed message, is used to reply 501 second base station 502 of first base station and does not receive first
The base station configuration change of base station 501 is requested.
In yet another embodiment, attached drawing 6 shows the flow chart of CoMP initialization procedure, and CoMP establishment process includes
CoMP request and CoMP are replied or CoMP failure, and wherein first base station 601 is also possible to central node.
In addition to the scheme of the base station role configuration in Fig. 4 and Fig. 5, base station role can also be matched by CoMP initialization procedure
It sets.
In step 610, first base station 601 sends CoMP request message to the second base station 602.
CoMP message includes cooperation feature, which is used to indicate the cooperation of first base station 601 and the second base station 602
Relationship, it as first base station 601 is not by control base station or the second base station 602 which, which includes the second base station 602,
One base station 601 by control base station.
When the cooperation relation in cooperation feature be the second base station 602 be not first base station 601 by control base station when, first
Mode carries out coordinated multipoint transmission in a distributed manner namely the interference elimination of minizone cooperates to be point for base station 601 and the second base station 602
Cloth.
When the cooperation relation in cooperation feature be the second base station 602 as first base station 601 by control base station, the first base
Stand 601 and second base station 602 coordinated multipoint transmission carried out with Centralized Mode, wherein first base station 601 is used as control base station, the
Two base stations 602 as by control base station, namely namely the interference of minizone eliminate and cooperate to be centralized.
CoMP request message further includes but is not limited at least one of following:
Type of message；
The Global base station ID: positive integer (1 ..., 4095 ...) of first base station；
The Global base station ID: positive integer (1 ..., 4095 ...) of second base station；
