摘要： A disclosed user apparatus is for use in a mobile communication system including a macrocell and a closed cell wherein unspecified users are allowed to access the macrocell and specified users are allowed to access the closed cell. The user apparatus includes a measurement unit configured to measure quality of a signal provided from a camped cell in an idle state at a predefined cycle, a cell search unit configured to measure quality of a signal provided from a neighbor cell at a predefined cell search cycle, and a cell reselection unit configured to reselect a cell depending on the cell search result. A frequency of the macrocell is at least partially identical to a frequency of the closed cell. If the user apparatus resides in the macrocell and a predefined reselection criterion is satisfied, the closed cell adjacent to the camped cell is reselected as a standby cell. The predefined reselection criterion corresponds to a state where the quality of the signal provided from the closed cell has been higher than or equal to the quality of the signal provided from the camped cell by a predefined threshold for more than a predefined reselection duration.

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： In resource measurement device 32, a measured value x of resource use condition is acquired in respect of the wireless resource to be monitored. Furthermore, in comparators 34 and 35, the measured value x is compared with the call admission threshold value xA of service A or with the call admission threshold value xB of service B, respectively. Comparison result selector 36 then selects one or other of the comparison results of comparators 34 and 35 in accordance with the type or degree of priority of the service of the call requested, identified by service identifier 33, and call admission control device 31 restricts new call admission in accordance with the selected comparison result. Thus, the call admission control method, communication system and base station device wherein deterioration of communication quality is suitably suppressed by call admission control in accordance with the service that is being utilized are provided in communication in which access is performed with shared resources.
