摘要： A base station includes a radio communication unit (82, 85) configured to wirelessly communicate with a mobile apparatus capable of communicating in both a first mobile communication system and a second mobile communication system and a network communication unit (83, 84) configured to communicate with a switching station in the first mobile communication system, and if a line setup instruction signal (Initial Context Setup Request) received at the network communication unit from the switching station is not due to initial access to the switching station by the mobile apparatus, the radio communication unit receives mobile apparatus capability information in the second mobile communication system (UE-UTRA-Capability) from the mobile apparatus after transmitting a line setup response signal (Initial Context Setup Response) to the switching station.

摘要： Upon detecting an opportunity to release E-RABs related to mobile stations, a mobility management entity transmits a single E-RAB release information message that collectively specifies E-RABs to be released to a base station communicating with the mobile stations. Subsequently, upon receiving the E-RAB release information message, the base station transmits a single E-RAB release information acknowledge message to the mobility management entity. Upon receiving the E-RAB release information acknowledge message, the mobility management entity updates information related to the E-RABs so that the information indicates release of the E-RABs.

摘要： In a method for managing cyclic shift codes used for reporting the CQI, when a new communication occurs between a base station and a mobile station, a cyclic shift code is allocated to the CQI report from the mobile station in accordance with a predetermined order of precedence. When the communication has ended or been disconnected, the cyclic shift code is released. In the allocating step, a cyclic shift code is allocated to the CQI report from the mobile station for the newly occurring communication, the allocated cyclic shift code having a precedence ranking that is lower than a precedence ranking of the allocated cyclic shift code allocated latest for the CQI report from another mobile station, being not used for CQI reports from other mobile stations, and having a highest precedence ranking in the predetermined order of precedence.

摘要： A radio base station determines at least any one type of subframe constituted of multiple system information subframes for sending system information to a mobile station, paging subframes for sending paging messages for the mobile station in idle mode, or on-duration subframes corresponding to on-durations at which the mobile station receives downlink control channel signals in discontinuous reception mode for the downlink control channel signals. The radio base station allocates, to the mobile station, inter-frequency measurement periods for inter-frequency measurement at the mobile station, while avoiding simultaneous occurrence of inter-frequency measurement periods and the subframes determined by the subframe determiner.
