Abstract: The present invention proposes a method for scheduling resource in a packet network and a network element for exchanging signaling with user equipments, wherein user equipments communicate therebetween using the resource allocated by network elements, said communication comprises talk-spurt periods during which data packets are transmitted and silent periods during which silence descriptor packets are transmitted, said method for scheduling resource comprising: said network element allocates resource for said user equipments for communication; both said user equipment and said network element detect the presence of said silence descriptor packet, and said network element determines the optimized number of resource unit(s) to be allocated to said user equipment during the interval for transmitting said data packet, based on the coding rate of said user equipment, the selected modulation coding scheme and the valid transmission times; the network element starts timing and the user equipment stops using the allocated resource if a silence descriptor packet is detected; when the timing finishes or a request for allocating resource is received from the user equipment before the end of said timing, said network element allocates the determined optimized number of resource unit(s) to said user equipment, and said user equipment begins to use said determined optimized number of resource unit(s); said network element determines the end of the interval for transmitting said data packet by detecting the silence descriptor packet.; and when both said user equipment and said network element detect a silence descriptor packet, said user equipment stops using said determined optimized number of resource unit(s), while said network element releases said determined optimized number of resource unit(s).

Abstract translation: 本发明提出了一种用于在分组网络中调度资源的方法和用于与用户设备交换信令的网元，其中用户设备之间使用由网元分配的资源在其间进行通信，所述通信包括在其中发送数据分组的通话时段 以及静默期间，其中发送静音描述符分组，所述调度资源的方法包括：所述网元为所述用户设备分配资源进行通信; 所述用户设备和所述网络元件都检测到所述静音描述符分组的存在，并且所述网络单元基于所述用户设备和所述网络单元确定在用于发送所述数据分组的间隔期间被分配给所述用户设备的资源单元的优化数量 所述用户设备的编码率，所选择的调制编码方案和有效的传输时间; 如果检测到静默描述符分组，则网元开始定时，并且用户设备停止使用分配的资源; 当在所述定时结束之前从用户设备接收到定时完成或分配资源的请求时，所述网络单元将确定的优化的资源单元数量分配给所述用户设备，并且所述用户设备开始使用所述 确定优化的资源单位数量; 所述网元通过检测静音描述符包确定发送所述数据包的间隔的结束; 并且当所述用户设备和所述网络元件都检测到静默描述符分组时，所述用户设备停止使用所确定的优化数量的资源单元，同时所述网络单元释放所确定的优化数量的资源单元。
