| 摘 要： | 在对GSM／GPRS(global system for mobile communications／general packet radio service)蜂窝系统现有典型信道分配策略FRA(fixed resource allocation)和DRA(dynamical resource allocation)及其排队策略进行分析的基础上，提出了基于DRA的改进策略DMC—DRA(dynamical minimum channels of packets for DRA)．新策略能动态改变GPRS包下限信道数，在FRA和DRA之间折衷，提高信道利用率、包传输时间、呼叫阻塞率等综合性能．

| Abstract: | Based on the analyses of the typical channel allocation schemes such as FRA (fixed resource allocation) and DRA (dynamical resource allocation) for GSM/GPRS (global system for mobile communications/general packet radio service) networks, an improved channel allocation scheme, DMC_DRA, was proposed, and its performances were analyzed. The new scheme may dynamically changes the minimum number of channels for a GPRS packet. In this way a compromise between FRA and DRA may be achieved to have better comprehensive performances such as channel utilization efficiency, packet transfer time and call blocking probability. |
