摘要： A downlink packet scheduling method is disclosed for a shared channel or a common channel in a mobile communication system between a base station and a mobile station, the method including a step in which the base station determines whether there is a waiting packet to be transmitted to the mobile station other than a current transmission packet; a step in which when it is determined that there is no waiting packet to be transmitted, the base station sets a stop period “t” in which packet transmission is temporarily stopped after the current packet transmission; a step in which the base station transmits information indicating the stop period “t” through a schedule information channel transmitting schedule information of downlink packets; and a step in which the base station stops the packet transmission to the mobile station during the stop period “t” after the current packet transmission.

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.

摘要： Embodiments of the present invention make it possible to reduce loss and delay of downlink user data transmitted at regular time intervals in a mobile communication system employing a hard handover method, and make it possible to easily perform high-quality handover solely by a handover-starting base station. A base station for transmitting downlink user data at regular time intervals to a mobile station is disclosed. The base station is configured to transmit a handover-command signal immediately after transmitting the downlink user data to the mobile station.
