摘要:
A radio physical channel is available to multiple logical channels commonly, and multiple radio physical control channels are provided concomitantly with the radio physical channel and include a commonly usable common control channel. A channel transmission apparatus includes a logical channel type determination unit determining a type of a logical channel, and a channel transmission unit transmitting an identifier of the UE in the radio physical control channel depending on the type of the logical channel. A scheme of identifying the UE in the radio physical control channel is modified depending on the type of the logical channel.

A data transfer method according to the present invention transfers user data of a mobile station from a handover source base station to a handover target base station through a transmission path, when the mobile station performs a handover. The data transfer method according to the present invention includes: determining, at the handover source base station, a priority order of the user data; determining, at the handover source base station, a transfer speed of the user data based on the priority order; and transferring, at the handover source base station, the user data to the handover target base station based on the determined transfer speed.

A radio base station transmits user common data provided from a user common data control apparatus connected to a communication network to a plurality of mobile stations by radio. The radio base station includes a frame loss detection unit configured to detect loss of user common data that occurs on a transmission route between the radio base station and the user common data control apparatus, and a timing adjustment unit configured to change transmission timing of the user common data for the mobile station according to the loss of the user common data.

A handover method according to the present invention includes the steps of: forwarding, at a handover-source radio base station (eNB), user data (A) for a mobile station (UE) to a handover-target radio base station (eNB) when it is determined that a handover processing is to be performed, the user data (A) being stored in the handover-source radio base station (eNB); activating, at the handover-target radio base station, a predetermined timer when transmitting a path switch request to a path control apparatus, and storing second user data for the mobile station received from the path control apparatus until the predetermined timer expires; and forwarding, at the handover-target radio base station, the stored second user data to the mobile station after the predetermined timer expires.

A radio base station (T-eNB) is configured to set up a data forwarding tunnel for forwarding user plane data to the radio base station (T-eNB) only for an access bearer for which the user plane data to be forwarded exists, when receiving a notification from a handover-source radio base station (S-eNB) as to whether or not the user plane data to be forwarded exists for each access bearer. The notification being made by using a handover request message for the mobile station (UE), and the access bearer being set up between the radio base station (T-eNB) and a upper level node (SGW).
摘要:
The present invention relates to a data transfer method which transfers user data of a mobile station, which is stored in a buffer of the handover source base station, from a handover source base station to a handover target base station, when the mobile station performs a handover. The data transfer method according to the present invention includes: determining, at the handover source base station, a transfer order of the user data; and transferring, at the handover source base station, the user data to the handover target base station based on the transfer order.
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.

A disclosed base station apparatus to be used in a mobile communication system includes a report signal receiving unit receiving a report signal from one or more user equipment terminals, a radio parameter adjustment unit adjusting radio parameters based on an analysis result of each report signal, a designation unit designating a report condition to be used for each user equipment terminal to determine whether to transmit the report signal and content to be reported in the report signal, and a report unit reporting the report condition and the content to be reported to the one or more user equipment terminals. Further, in the base station apparatus, the report condition is satisfied when a transmission source of a downlink reference signal is a specific cell, and the content to be reported includes a received quality value of the downlink reference signal.
