摘要
GPRS是以GSM网络为基础建立起来的被称为2.5G的无线分组应用,随着移动通信的发展,GPRS业务达到了空前的火热程度。在话音优先的前提下,GSM话音与GPRS数据共享无线信道。因此在GPRS业务用户分布密集的大中型城市区域,GPRS业务经常会遭遇信道资源短缺危机。为了改善这个问题,在GPRS信道数量已经限定的前提下,本文提出了一个关于GPRS信道资源智能分配的改进方案。改进方案采用适当算法将各MS发出的GPRS服务请求划分优先等级,再综合影响无线信道利用率的各个因素以及QoS参数,最终给出使无线信道利用率最优化的服务解决方案。本文最后还分析了这种改进方案对原系统配置、规模等方面的影响。
GPRS is one kind of wireless packet applications which is GSM-based network and known as the 2.5G technology. With the development of mobile communication, GPRS Services are becoming really hot nowadays. On the premise of voice have the higher priority, GSM and GPRS data share the radio channels. Therefore, GPRS services are often encountered crisis of channel resource shortage in the large and medium-sized urban areas that have dense service-users. To solve this problem, on the premise of the GPRS channel amount not increasing, this paper brings up an improved scheme about intelligent allocation of resources. Firstly, the improved scheme uses one appropriate algorithm to prioritizing the GPRS service requests which is applied by MS. Secondly, the scheme combines and analyses the QoS parameters and various factors which effect wireless channel utilization. Finally, the improved scheme provides the optimal solution of radio channel service utilization. In the end of this paper, the improved scheme＇s effects on the original system in the field of configuration, size and other aspects are also analyzed.
