摘　　要：传统的位置汇报是通过查询方式,经过主控制器下发指令,对应终端收到消息后发起信道申请,再由控制器分配信道,接着终端跳转到传输信道再发送数据到上行信道的过程。该流程耗时且无序。经过分析,可以让终端与主控制器在首次建联时分配好固定信道,主控制器在控制信道不停广播当前窗口。终端可以根据首次建联时分配的窗口,做出上报数据或为下一个窗口准备数据的决定。从而达到分时、复用、有序的目标,以极大地提高系统吞吐量。Traditional location reporting is a process where the main controller issues instructions through a query method,and the corresponding terminal initiates a channel application after receiving the message.The controller then allocates the channel,and the terminal jumps to the transmission channel before sending data to the uplink channel.This process is timeconsuming and disorganized.After analysis,it is possible to allocate a fixed channel between the terminal and the main controller during the first connection,and the main controller continuously broadcasts the current window on the control channel.The terminal can make decisions to report data or prepare data for the next window based on the window allocated during the first connection establishment.In order to achieve the goal of time sharing,reuse,and order,and greatly improve system throughput.

关 键 词：位置信息 分配窗口 分时有序 非确认式用户数据报 系统吞吐量
