    • The present invention relates to an improved wireless communications system capable of efficiently transmitting smaller-sized data packets (e.g. 10 to 20 byte length) that are frequently delivered (e.g. 10 to 20 msec.) to mobile nodes on the communications system, such as voice communications. Because an uncompressed TCP/IP or UDP/IP header length is disproportionally large compared to the smaller-sized data packets, the bandwidth on the backhaul connection between the base station controller unit (BSC) and the base transceiver station (BTS) is not being utilized as efficiently as possible. The present invention optimizes the transmission of information packets on the backhaul connection by using an IP Adaptation Layer (IPAL) protocol to map the user connections, eliminate the large header on information packets having smaller-sized data packet sizes, and concatenating the data packets into an IPAL information packet for tunnelling on the backhaul connection. In this manner, the present invention more efficiently uses the available bandwidth on the backhaul connection by selectively reducing the overhead (e.g. headers) of the information packet transmission.
    • 本发明涉及一种改进的无线通信系统,其能够有效地发送经常传送(例如10至20毫秒)的通信系统上的移动节点(例如语音)的较小尺寸的数据分组(例如10到20字节长度) 通信。 由于与较小尺寸的数据包相比,未压缩的TCP / IP或UDP / IP标头长度不成比例,基站控制器单元(BSC)和基站收发器(BTS)之间的回程连接的带宽不是 尽可能高效地利用。 本发明通过使用IP适配层(IPAL)协议来映射用户连接来优化回程连接上的信息分组的传输,消除具有较小尺寸数据分组大小的信息分组上的大标题,并将数据分组连接成 用于在回程连接上隧道的IPAL信息包。 以这种方式,本发明通过选择性地减少信息分组传输的开销(例如头部)来更有效地使用回程连接上的可用带宽。

    • A radio access network (24) comprises a control node (26) which performs a dynamic adjustment of a priority class afforded to a packet data connection with a user equipment unit. The dynamic adjustment of a priority class performed by the control node is based on a throughput criteria (112) communicated to the control node by the user equipment unit. In one example embodiment, the dynamic adjustment is performed by a dynamic priority regulator application program (100) which executes at node compares actual data packet throughput for the packet data connection with the throughput criteria, and on the basis of the comparison performs a change of the priority class accorded to the packet data connection. In accordance with the change of the priority class the control node requests a radio base station node to change a throughput rate for the packet data connection. The control node performs the dynamic adjustment of a priority class within priority class constraints also communicated to the control node by the user equipment unit.

    • Network element (300) with reference clock (302) is fixed to base station (102) with local clock (330) via asynchronous data transmission connection (312). Reference clock sends time stamp signal (308) over connection. Station (102) receives time stamp signal and calculates deviation of local clock time from reference time. Based on deviation, speed correction factor is output and applied to local clock. A frequency synthesizer (212) generates frequency based on the corrected local clock. An independent claim is also included for the method of performing frequency synchronization of base station.
