摘要： To reduce the number of cells in which a “Measurement Subframe Pattern” is broadcasted, in the mobile communication method according to the present invention, a radio base station eNB#2 broadcasts setting broadcast information in a cell #2 when a radio base station eNB#1 broadcasts a “Measurement Subframe Pattern” in a cell #1. A MOBILE STATION UE in Idle mode receives the “Measurement Subframe Pattern” broadcasted in the cell #1 in order to perform a “Measurement process” based on the “Measurement Subframe Pattern” when the MOBILE STATION UE detects, based on the setting broadcast information broadcasted in the cell #2, that the “Measurement Subframe Pattern” is broadcasted in a neighbor cell.

摘要： A plug-and-play radio base station autonomously establishes X2 logical interfaces and S1 logical interfaces with existing base stations and upper nodes. A new radio base station which is installed in a network advertises an IP address of the new radio base station over a transport network. An existing radio base station or an upper node which receives the IP address detects the number of hops from the new radio base station to the existing radio base station or the upper node. An initial logical interface with the new radio base station is established when the detected number of hops is below a predetermined threshold.
