    Abstract: A mobility control method and device that can suppress an increase of location registration signaling are provided. In a mobile communication network including cells (21a, 21b) of multiple types differing in cell size, priorities for mobility control are set on individual neighbor cells (22a-29d) or individual neighbor cell types, and mobility control is performed such as to select a neighbor cell with a priority lower than that of a currently staying cell when a mobile terminal is moving faster than a predetermined speed (Operations 303-306).

    Abstract: A disclosed base station gateway apparatus has a C-plane processing unit and a U-plane processing unit. When a mobile station performs handover from a subordinate source base station to a subordinate target base station, the C-plane processing unit terminates S1AP signaling received from the source base station and the target base station without relaying the S1AP signaling to a mobility management apparatus. The U-plane processing unit inserts, into U-plane data that is received from a serving gateway apparatus and that is to be transferred to the source base station, an end marker indicating that the U-plane data is the last data at a predetermined timing, and switches the transfer destination of the U-plane data, received from the serving gateway apparatus, from the source base station to the target base station at a timing immediately after the end marker is inserted.

    Abstract: A base station apparatus (1) is configured to send a first information element to an inter-base-station gateway (3). The first information element explicitly or implicitly indicates whether a relay operation is necessary. The relay operation is an operation in which the inter-base-station gateway (3) relays a data packet destined for or sent from a radio terminal between the base station apparatus (1) and another base station (2). It is thus, for example, possible to contribute to enabling a base station or an inter-base-station gateway to select whether a relay operation by the inter-base-station gateway should be performed at the time of an inter-base-station handover.

    Abstract: A communication control method includes: transmitting, by a second radio base station (103) adjacent to a first radio base station (100), an attribute value relating to a second cell (102) under control of the second radio base station (103) to the first radio base station; receiving, by the first radio base station, the attribute value relating to the second cell; comparing, by the first radio base station, the attribute value relating to the second cell with an attribute value relating to a first cell under control of the first radio base station; and executing, by the first radio base station, processing for matching the attribute value relating to the second cell with the attribute value relating to the first cell in accordance with a predetermined criterion when the received attribute value relating to the second cell is different from the attribute value relating to the first cell.

    Abstract: A radio communication system, a radio station, a network operation management apparatus, and a network optimization method are provided that can optimize a performance of the entire system even when network optimization is performed individually. In the radio communication system including multiple radio stations (10, 20, 30) and network operation management apparatuses managing the radio stations, network optimization is autonomously performed. A first radio station (10) notifies first optimization information regarding network optimization in a cell (10a) of the first radio station to at least one of another second radio station (20/30) that is different from the first radio station and a network apparatus that manages the second radio station (101).
