摘要

移动流媒体被认为主要是一种3G服务，提供有保证的比特率、错误率和延迟界限。本文分析了2.5G环境下流媒体服务的可行性。GPRS Rel。97允许足够的带宽用于流媒体，但它不能保证比特率或延迟。我们研究了不同的QoS参数配置，以找到GPRS Rel上流的最佳值。97年。如果选择了正确的QoS配置文件，它的错误保护就足够好了。GPRS小区重选会给流带来额外的问题，因为几秒钟的数据可能会丢失。结果表明，尽管存在所有这些限制，在GPRS环境中仍然可以进行流传输，并且甚至可以在部署3G网络之前启动该服务。

3GPP streaming over GPRS Rel '97

Mobile streaming is thought to be mainly a 3G service offered with guaranteed bit rates, error rates and delay bounds. In this paper we analyze the feasibility of streaming services in a 2.5G environment. GPRS Rel. '97 allows enough bandwidth for streaming, but it cannot guarantee bit rates or delays. We study different QoS parameter configurations to find optimal values for streaming over GPRS Rel. '97. Its error protection is good enough, if the correct QoS profile is chosen. GPRS cell reselections cause additional problems for streaming, since several seconds of data can be lost Results show that despite all the limitations, streaming is possible in a GPRS environment and this service can be started even before the deployment of 3G networks.
