A Mobile Station, an MS (700), for a GERAN system, the MS (700) being arranged (705, 710, 750, 730) to receive bursts from a Base Transceiver Station, a BTS, each of said bursts being modulated with a modulation type chosen from one of a number of modulation types. The MS is arranged (730, 740) to identify bursts from the BTS which may comprise information for the MS by identifying if a Training Sequence Code, a TSC, which is comprised in received bursts corresponds to a TSC which the MS has been assigned, the MS being arranged (705, 710, 750, 730, 740) to be assigned a first and a second TSC to be used for at least one of said modulation types.

The present disclosure relates to a method and a transmitting unit for reducing a risk of transmission stalling between a transmitting unit and a receiving unit in a communication network system comprising said transmitting unit arranged to transmit data blocks to said receiving unit. Each data block comprises a block sequence number and transmitted data blocks are stored in a transmission buffer. A transmission buffer window is arranged to control the flow of retransmission of said transmitted data blocks. When the block sequence number has been acknowledged in a piggybacked acknowledgement/negative acknowledgement field, it is only set as acknowledged upon receipt of a packet uplink acknowledgement/negative acknowledgement message or a packet downlink acknowledgement/negative acknowledgement message comprising an acknowledgement for said block sequence number.

A method in a Gateway General packet radio service Support Node, GGSN, for transferring a service identifier from a packet core network to a radio network is provided. The GGSN adds a service identifier in a General packet radio service Tunneling Protocol for User Plane, GTP-U, header extension of a data packet. The service identifier comprises information about what service and/or traffic pattern that the packet concerns. The GGSN sends the data packet with the GTP-U header extension to a radio network.

A method of performing congestion notification for a data transmission (10) from a sender (14) to a receiver (11) is described. Furthermore, nodes for such a transmission as well as methods of controlling such nodes are described. The data transmission involves a first node (12) and a second node (13) between said sender and receiver. The data packets pass from said second node to said first node towards said receiver. The method comprises: —sending (S82) a message (15) from said first node to said second node, said message relating to a decision on whether to notify said receiver of a congestion condition in said data transmission, —sending (S83) an explicit congestion notification (16) from said second node to said receiver if it is decided to notify said receiver of said congestion condition.
摘要:
A base station subsystem (BSS) and a method are described herein for improving an Access Grant Channel (AGCH) capacity when mobile stations establish an uplink Temporary Block Flow (TBF) triggered by a small data transmission (SDT) or an instant message transmission (IMT). Plus, a mobile station (MS) and a method are described herein for improving the AGCH capacity when the mobile station establishes an uplink TBF triggered by a SDT or an IMT.
摘要:
A base station detects the transition of a mobile station from a DTX mode to a continuous transmission mode. The base station schedules an uplink transmission by the mobile station during an uplink transmission period while the mobile station is in DTX mode and receives an uplink LLC PDU from said mobile station during the scheduled uplink transmission periods. The base station determines the operating mode of the mobile station based on the size of the received uplink LLC PDU.

The invention proposes to introduce a method for a Radio Access Network for providing “Local Switching” between call legs of a call. Within said method the Radio Access Network receives a call identifier for a leg of a call from a Core Network to be handled by the Radio Access Network. The Radio Access Network stores said received call identifier, compares said received call identifier with stored call identifiers for call legs of calls via said Radio Access Network. If said received call identifier matches a stored call identifier the Radio Access Networks establish local switching of call legs identified by the matching call identifier. In an alternative embodiment, the invention proposes to introduce a method for a Core Network for providing local switching for call legs of a call. Within said method the Core Network receives or generates a call identifier for a leg of a call. The Core Network stores said received call identifier and identifies a respective Radio Access Network for said leg of said call. Thereafter, the Core Network compares said call received identifier with stored call identifiers for call legs of calls via said identified Radio Access Network. If said received call identifier matches a stored call identifier enforce local switching of call legs identified by the matching call identifier. The invention furthermore provides for respective Nodes of the respective Networks employing the invention.

A method may include receiving, by a user equipment incapable of transmitting and receiving simultaneously, a schedule to transmit data on an uplink, detecting, by the user equipment, whether there is data to be transmitted on the uplink, and receiving, by the user equipment, during a time corresponding to the schedule, data associated with a downlink, when it is determined that there is no data to be transmitted.

摘要:
The present invention relates to a method of reducing setup delay for an uplink message from a user terminal (UT) in a delay sensitive service in a radio telecommunications system, such as a push to talk service (PoC), by predicting that delay sensitive data is about to be transmitted, sending, as a response to the prediction, a connection setup signal from the terminal to a basestation subsystem (BSS) in order to set up an early uplink radio connection, and transmitting the delay sensitive data via the early uplink connection. There is also provided a user terminal (UT) and a radio telecommunications system.
