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.

A base station includes a congestion state determination unit that determines whether the base station is in a congestion state; a barring target setting unit that sequentially sets targets of barring among a plurality of the targets of the barring when a determination is made that it is the congestion state; a barring time interval setting unit that sets a time interval of the barring based on the congestion state when the determination is made that it is the congestion state; and a transmitter that transmits information representing the targets of the barring and information representing the time interval of the barring to the user equipment.
摘要:
A radio base station includes a step-A where a second radio access network device inside a second radio access network notifies a first radio access network device inside a first radio access network of access information comprising at least one of either load information or barring information. Step-B includes a mobile station on standby in a cell under the first radio access network device, upon moving to an area in which the cell under the first radio access network device and the cell under the second radio access network device overlap, transmits a communication initiation request signal to the first radio access network device. Step-C includes the first radio access network device decides regarding in which of the cell under the first radio access network device or the cell under the second radio access network device. The communication of the mobile station should be initiated based on the access information.
摘要:
A mobile communication method according to the present invention includes the steps of: (A) transmitting, from a radio base station (eNB) to a plurality of cells designated by a transmission request received from a switching center (MME), broadcast information; and (B) transmitting, from the radio base station (eNB) to the switching center (MME), a transmission response which includes an information element to which the number of cells and identification information of the cells are set, in accordance with the transmission request; wherein, in the step (B), when the broadcast information was not successfully transmitted to all the plurality of cells, the radio base station sets “0” to the number of cells in the information element.
