摘要： There is described a method and apparatus for managing security for a connection between a user device and a communications network comprising at least one base station and a core network. In one embodiment, the method includes receiving at the core network security capability information for the user device connecting to the communications network. Security capability information for the base station is then obtained from memory or from the base station itself. The security capability information for the user device and the security capability information for the base station is then processed in the core network to select a security policy for a connection between the user device and the base station and the selected security policy is transmitted to the base station.

摘要： A communications device in the form of a base station or communications node such as an eNodeB communications node selects one of a plurality of modulation and coding schemes for a control channel for a user communications device on the basis of the range which is specified by the location or channel condition within a cell of the user communications device. The selected modulation and coding scheme are identified to the user communications device separately from the control channel. In one example, the selected modulation and coding scheme is identified to the user communications device by way of a 2-bit code which may be provided within a MAC control block or appended to a MAC Data PDU.

摘要： In a telecommunication system, Service Data Units (SDUs) are received and copies are stored in an SDU management buffer 101. The SDUs are concatenated and segmented 105 to generate Protocol Data Units (PDUs), which are stored in a transmission buffer 111 for transmission to a mobile communication device. A feedback message 113 is sent to the SDU management buffer identifying an SDU that may be removed when, for Unacknowledge Mode (UM) data, the PDUs corresponding to that SDU have been forwarded from the transmission buffer or when, for Acknowledge Mode (AM) data, receipt of the PDUs corresponding to the SDU has been acknowledged by the mobile communication device. In response to receipt of the feedback message, the identified SDU is removed from the SDU management buffer. A system is also proposed to provide handover in which a source base station stops downlink traffic on detecting a handover in progress whereas the uplink traffic is separately stopped by the user equipment on receiving a handover command. A new buffer management entity is provided in the outer ARQ entities for controlling the storage of data packets that are to be forwarded to a target base station in order to prevent or minimise packet loss.

摘要： A system is proposed to provide handover in a mobile telecommunications environment, particularly applicable to 3GPP networks, which does not increase signalling overhead but minimises user data loss during handover. In the modified system, PDCP SDUs with Sequence numbers are buffered and retransmitted as necessary. At the time of handover, SDUs not received by the user device are forwarded to the target base station for forward transmission to the UE. The handover procedure is designed to minimise packet loss whilst keeping to a minimum the duplication of packet transmission over the air interface.

摘要： A system is proposed to provide handover in a mobile telecommunications environment, particularly applicable to 3GPP networks, in which a user device, such as a mobile telephone provides a buffer status report to the target base station during a handover procedure. The target base station uses this status report to allocate appropriate resources for uplink data to be transmitted from the user device to the target base station.

摘要： A system is proposed to provide buffer status reporting in a mobile telecommunications environment, particularly applicable to 3GPP networks, which allows the base station to perform Quality of Service aware uplink resource allocation. The system uses two types of buffer status reports - Absolute Buffer Status Reports and Relative Buffer Status Reports. Absolute Buffer Status Reports are sent at application start up or when the buffer level is above or below set threshold values. Otherwise Relative Buffer Status Reports are sent, which encode the present buffer level in terms of the difference from the last transmitted Absolute Buffer Status Report.

摘要： A mobile communications system is proposed in which mobile communications devices are arranged to carry out signal measurements on the signals received from neighboring cells. The bandwidth over which these signal measurements are carried out is determined in dependence upon the bandwidths of the neighboring cells and is signalled to the mobile communication device by a serving base station.
