The base station can sub-district of unique identification at the cell ID that need guarantee when the RN devices allocation cell ID to distribute; The cell ID that distributes such as the cell ID of the sub-district that can check self-management and for other RN, guarantee can not be identical with above-mentioned these signs.
In the step 503, the base station can be with each cell ID respectively as assignment information after having distributed cell ID, such as having distributed 3 cell IDs, then with each cell ID as an assignment information, 3 assignment information are promptly arranged; Accordingly, in the step 504, RN equipment respectively as a cell ID, identifies each cell ID each assignment information respectively as a sub-district corresponding district.
The base station can also be with the partial bit of each cell ID respectively as assignment information after having distributed cell ID; Accordingly, in the step 504, RN equipment is filled all the other bits of cell ID after receiving assignment information, and according to the cell ID after filling, confirms each sub-district corresponding district sign.Such as cell ID is ECGI; Need to distribute 2 cell IDs; Then the base station can send to RN equipment as an assignment information respectively by back 8 bit with each ECGI; RN equipment after receiving two assignment information, according to preceding 44 bits of the ECGI of Donor cell respectively with two that receive after 8 bits form two new ECGI, and the ECGI that each is new is as a sub-district corresponding district sign.
The partial bit of each cell ID can be saved transfer resource as the mode of assignment information respectively, improve efficiency of transmission and resource utilization.
In the step 503, the base station can also be from all cell IDs that distribute selected a part of cell ID, each selected cell ID respectively as assignment information, is remained partial bit in each cell ID respectively as an assignment information; Accordingly, in the step 504, the bit number that RN equipment takies according to cell information just knows that which assignment information is complete cell ID, and which assignment information is the part cell ID.
In the step 500, RN equipment can be set up in the process at X2 interface, or before the X2 interface foundation, or send cell informations to base station 20 in the X2 interface config update process.
Concrete, RN equipment can place RRC message or X2-AP message to send the cell information that needs to send.
In the step 503, the base station can place RRC message or X2-AP message to send the assignment information that needs to send.
It is relevant that which kind of message concrete RN equipment and base station adopt follow RN equipment under what scene, to send cell information respectively, and particular content can repeat no more at this referring to Fig. 7～Figure 11.
The base station can also report the OAM equipment that is connected with self with the cell ID that distributes after being RN devices allocation cell ID.
RN equipment can also report the OAM equipment that is connected with self, i.e. RN OAM equipment with the cell ID of confirming after having confirmed sub-district corresponding district sign.
Preferable, in the step 504, RN equipment can also assign by the informing base station cell ID after having confirmed sub-district corresponding district sign.
As shown in Figure 6, the embodiment of the invention confirms that the method for cell ID comprises the following steps:
The quantity that step 601, RN equipment distribute the sub-district of cell ID is as required confirmed cell information, and sends cell information to the base station.
In the step 601, RN equipment will distribute the quantity of sub-district of cell ID as cell information; Or RN equipment with each cell ID particular value as cell information.
In the step 602, when assignment information was cell ID, RN equipment as cell ID, and was confirmed each sub-district corresponding district sign with assignment information;
When assignment information was the partial bit of cell ID, RN equipment was filled all the other bits of cell ID, and according to the cell ID after filling, confirmed each sub-district corresponding district sign.
In the step 601, RN equipment is set up in the process at X2 interface, or before the X2 interface foundation, or send cell information to the base station in the X2 interface config update process.
Further, RN equipment sends cell information through RRC message or X2-AP message.
Can further include after the step 602:
RN equipment reports the OAM equipment that is connected with self with the cell ID of confirming.
Can further include after the step 602:
RN equipment informing base station cell ID has assigned.
Wherein, the particular content of step 601 and step 602 can be respectively identical referring to step 500 and step 504, repeat no more at this.
Be that ECGI is that example is elaborated with cell ID below, cell ID is that the process of process and ECGI of PCI is similar, repeats no more.
As shown in Figure 7, first kind of X2 interface of the embodiment of the invention set up and distributed the method for cell ID to comprise the following steps: in the process
After step 701, the RN device power-up, set up in the process of X2 interface, in X2 SetupRequest (X2 sets up request) message, report the number of cells of RN equipment control to DeNB with DeNB.
The number of cells that step 702, DeNB ask according to RN; Each cell allocation sub-district ECGI for RN; And situation about setting up according to X2 interface; Send to RN equipment through X2 Setup Response (X2 sets up response) message or X2 Setup Failure (X2 sets up failure) message, promptly set up and successfully send X2 Setup Response, set up failure and send X2 Setup Failure.
