摘要： In a communication system, a token manager corresponding to a generated or arriving packet is determined, tokens corresponding to a target transmission rate limit are generated, and a corresponding packet is at least one of dropped and provided in consideration of the amount of the tokens created and the size of the generated packet. Through such a method, a packet transmission rate can be limited to the target transmission rate. In addition, when there is traffic of various service classes, service can be differentially provided according to the priorities of the service classes.

摘要： A method and an apparatus for load balancing a serving subcell providing a data service to one or more user equipments in a cellular communication system are provided. The method includes calculating a load metric by using a radio resource occupation rate of data traffic in one or more scheduling types except for a Best Effort (BE) scheduling type, determining whether the serving subcell is in an overload state by using the load metric, and triggering a load balancing algorithm when it is determined that the serving subcell is in the overload state. Accordingly, the load metric used for load balancing may be defined to have a value closer to an actual free load, and thus the load balancing may be efficiently performed.
摘要翻译：提供了一种用于将蜂窝通信系统中的一个或多个用户设备提供数据服务的服务子小区负载平衡的方法和装置。该方法包括：通过使用除了最佳努力（BE）调度类型之外的一种或多种调度类型中的数据业务的无线电资源占用率来计算负载度量，通过使用负载度量确定服务子小区是否处于过载状态，并且当确定服务子小区处于过载状态时触发负载平衡算法。因此，用于负载平衡的负载度量可以被定义为具有更接近实际空闲负载的值，因此可以有效地执行负载平衡。

摘要： Provided is an apparatus and method for transmitting/receiving a service guide in a Broadband Wireless Access (BWA) system. In the method, a service guide request message is transmitted to A MultiCast and BroadCast Service (MCBCS) server. A service guide response message including a service guide is received from the MCBCS server. The service guide is stored in a user terminal. A variety of factors necessitating the maintenance of an awake state of a user terminal can be eliminated. Thus, it is possible to prevent a waste of power, which may be caused by periodic uplink transmission due to the awake state of the user terminal, and a waste of air resources necessary for a signaling process.

摘要： A method and apparatus for managing a buffer of a Radio Access Station (RAS) in a communication system are provided. An available buffer space determiner sets a threshold for each service class for scheduling packet input/output of the buffer according to priority of a service class, estimates and stores, upon receipt of a packet at the buffer, an available space size of the buffer after the packet reception, compares the estimated available space size of the buffer with a first threshold corresponding to a first service class indicative of a service class of the packet, and schedules packet input/output of the buffer according to the comparison result. A processor module schedules packet input/output of the buffer according to an output of the available buffer space determiner. The present invention can improve quality of services through service differentiation based on priorities of service classes and buffer management based on characteristics of the corresponding service traffics.
