A base station includes a system information creating unit that creates first system information for barring communication and second system information for not barring; a timing determination unit that classifies user equipment into groups based on timings of the user equipment being in an idle mode to be activated in every discontinuous reception period, and that determines, for each of the groups, a timing of transmitting a paging signal; and a transmitter that transmits the paging signal to the user equipment of some of the groups, and subsequently the first system information; that switches transmission of the first and second system information, so that a ratio between a number of transmitting the first system information and that of the second system information corresponds to a barring ratio; and that transmits the paging signal to the user equipment of the some of the groups, and subsequently the second system information.
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.

A base station includes a connection processing unit that performs connection processes between user terminals registered in a user terminal registration unit and the base station, and between user terminals other than the user terminals registered in the user terminal registration unit and the base station; a resource amount measurement unit that measures an amount of resources utilized by the base station; and a call disconnection user terminal selecting unit that selects, when the resource amount measurement unit measures that the amount of the resources is greater than or equal to a predetermined threshold value, the user terminal for which a call is to be disconnected, among the user terminals other than the user terminals registered in the user terminal registration unit. The connection processing unit disconnects a connection with the user terminal for which the call is to be disconnected.

A base station includes a call connection acceptance determination unit that determines, when a call connection request signal from the user terminal is received, whether a call connection request from the user terminal is acceptable, based on an amount of resources that is used by the base station; a redirection-setting unit that sets, when the call connection acceptance determination unit determines that the call connection request from the user terminal is not to be accepted, a different base station to which the user terminal is to be redirected; and a notification unit that reports information representing the different base station that is set by the redirection-setting unit to the user terminal.
摘要:
During a transition procedure from a first communication system to a second communication system, when the priority of a second communication call, whose setup is requested, is the first priority, the second communication system does not set up the bearer of a first communication call between the second communication system and the mobile communication terminal, and notifies the first communication system that the setup of the first communication is not possible, but the setup of the second communication call is possible. When notified that the setup of the first communication is not possible, but the setup of the second communication call is possible, the first communication system aborts the handover procedure, and instructs the mobile communication terminal to switch to the second communication system by another procedure.

A base station is disclosed. The base station includes: a reconnection setting information generation unit configured, in a case where handover is requested from a first base station, after a reconnection request signal is received from a mobile apparatus, to generate reconnection setting information to be used for specifying the mobile apparatus; a transmission unit configured to transmit a reconnection request signal to the first base station; a receiving unit configured to receive reconnection setting information to be used for specifying the mobile apparatus from a second base station that is a destination of handover of the mobile apparatus after the second base station receives a reconnection request signal from the mobile apparatus; a reconnection setting information holding unit configured to hold the reconnection setting information; and a connection processing unit configured to perform reconnection processing with the mobile apparatus by using the reconnection setting information held in the reconnection setting information holding unit in accordance with a reconnection request signal from the mobile apparatus after initial connection processing between the second base station and the mobile apparatus.

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.
