Abstract
The invention discloses a MRS (Mobile Relay Station) PCI (physical cell ID) distribution method. The method comprises the following steps: step A, a PCI distribution detection list is configured at the terminal of a macro base station of each cell; step B, information interaction of the PCI distribution detection lists can be carried out between the macro base station of the cell in which the MRS locates and macro base stations of the cells adjacent to the cell in which the MRS locates so as to predict a possible PCI collision caused by the MRS; step C, if a collision is predicted, the macro base station of the cell in which the MRS locates can redistribute a PCI for the MRS to avoid the predictable collision. In the invention, the PCI of the MRS is configured at the terminal of the macro base station to detect the MRS entering in the cell in advance and can be changed in advance if a collision happens, thus avoiding the happening of PCI collision; besides, the invention transfers the work of PCI configured by an OAM (Operation Administration and Maintenance) to the macro base station in which the MRS locates, so the delay brought from the OAM configuration can be avoided; and meanwhile, the monitoring and reporting works of the MRS can be saved, the processing load and the signaling cost of the MRS can be alleviated and the backhaul link resource can be saved.
