摘要： A system and method for scheduling packet transmissions, whereby a Base Station System (BSS) part provides scheduling-related information to a Switching System (SS) part for scheduling of LLC frames, which includes information about the total number of packet data service radio links in the cell, and for each user, the bandwidth per link. Consequently, the SS can determine the required link utilization and hence the transmission time for each data packet the SS submits for transmission over the radio links. As such, the SS can control all end-to-end QoS quantities for each data packet, and how these quantities are affected by the SS scheduling of the LLC frames to the BSS. In this way, the SS can completely control how QoS agreements with users are met.

摘要： A wireless terminal (30) communicates across a wireless interface with a Long Term Evolution (LTE) radio access technology network (22-1) and a circuit switched network (22- 2). The wireless terminal (30) establishes a circuit switched call with the circuit switched network (22-2); maintains a packet switched session with the Long Term Evolution (LTE) radio access technology network (22-1) during establishment of the circuit switched call; and, multiplexes transmissions of the packet switched session with transmissions of the circuit switched call.

摘要： A wireless terminal (30) is capable of communicating with a first network (22- 1) and a second network (22-1, 22-3), the first network (22- 1) being an LTE network. A wireless terminal method comprises (prior to making a request to participate in a circuit switched call with the second network) the wireless terminal (30) camping on a respective selected cell (of each of the first network and the second network and thereby having tuned to both the selected cell for the first network and the selected cell for the second network. In view of already camping on the selected cell of the second network, the wireless terminal (30) does not make a measurement with respect to a cell of the second network in a time period between the making of the request to participate in the circuit switch call and actual establishment of the circuit switched call with the second network.

摘要： The invention discloses a method (1100) for a cellular wireless access TDD system (100) with a base stations (120, 220) for respective cells (110, 210) in the system, where each cell can accommodate at least a first user terminal (130, 230). The user terminals can receive traffic from their base stations during a down link period, and can transmit traffic to their base stations (120, 220) during an up link period (UL). There is a first guard period (TDu) at the transition from down link to up link, and a second guard period (TUD) at the transition from up link to down link. The method comprises measuring the interference level in a second plurality (110, 210) of cells during part of the time between two consecutive down link periods, and varying the duration of said first and/or second guard period in said second plurality of cells (110, 210) according to the interference level.

摘要： In a packet-based communication network ( 10 ) polling of connected user equipment is performed according to a first type (T1) and a complementary second type (T2). Upon receiving polling according to type one (T1) a user equipment ( 30 ) is allowed to transmit user data packets (UP) if any are available, otherwise the user equipment ( 30 ) can remain silent. In response to polling according to type two (T2), the user equipment ( 30 ) is required to either transmit an available user data packet (UP) or a dummy data packet (DP).

摘要： The technology described relates to management of data packets and buffers comprising segments of data packets in a mobile communication system. Information associated with data packet segments is analyzed by a Base Station System (BSS) housing a data buffer. Based on this information analysis, the BSS can identify those segments in the buffer that constitute a complete data packet. Once identified, the segments can be discarded from the buffer. The information can include size information, whereby the analysis comprises pairwise comparing the size of a current segment with the size of a next consecutive segment. This size comparison enables identification of a first segment and a last segment of the complete data packet. The information could also, or alternatively, include a notification provided in the header of the segment. This notification identifies the associated segment as the first or last segment of the data packet or an intermediate segment.

摘要： A method ensures that a reduction in data throughput is minimized in the event of a cell change in a GPRS network. When it is determined that cell change is appropriate for a mobile station, the BSS ensures that no further data for the mobile station is transmitted form the SGSN, and then continues to transmit all buffered data to the mobile station. The throughput may be deliberately reduced for a part of this time, so that the system timers become adapted to the reduction in throughput which will occur at the cell change. When the buffer has been emptied, the cell change is effected and, thereafter, that mobile station is prioritised in the BSS, in order to allow any buffered data on the uplink or downlink to be cleared.
