A mobile communication system according to the present invention comprising a plurality of Un radio bearers set between the plurality of mobile stations UE and the relay node RN, each of Un radio bearers for a predetermined QoS set for different mobile stations UE is configured to be mapped to a Un radio bearer for the predetermined QoS set between the relay node RN and the radio base station DeNB.
摘要:
A radio base station includes a mobile communication system, a relay node and a radio base station connected via a radio bearer. A mobile station is configured to conduct a handover process between the state in which a radio bearer is set with the relay node in order to communicate via the relay node and the radio base station, and the state in which a radio bearer is set with the radio base station in order to communicate via the radio base station. The mobile station is configured such that during the handover process, control signals involved in the handover process are sent and received via a radio bearer between the relay node and the radio base station.
摘要:
A base station used in a packet transmission system in which shared user data to be selectively received by a user are transmitted using a shared data channel from one or more base stations to one or more mobile stations is provided. The base station includes means configured to provide user control data associated with transmission of the shared user data; means configured to provide notification data that include notification information used to select the shared user data and group identification information for specifying the notification information; and means configured to generate an associated control channel that is associated with the shared data channel and includes the user control data and the notification data, the associated control channel and the shared data channel being transmitted from the base station to the mobile station. The generated associated control channel is transmitted from the base station to the mobile stations.
摘要:
The present invention provides a data transmission system where MBMS data are transmitted to a mobile station in synchronization among multiple base stations without use of any central control node for controlling the multiple base stations. The data transmission system includes a communication node managing user common data, one or more radio base stations coupled to the communication node and one or more mobile stations. In the system, each of the one or more base stations is synchronized with absolute time commonly used by the base stations. The communication node includes a reception unit receiving the user common data for one or more users from a provider and a determination unit determining through communications with the one or more base stations a transmission timing when the one or more base stations transmit the user common data to the mobile stations.
