摘要:

本文介绍了PoC业务应用到TD-SCDMA系统的技术背景和现有技术方案,并给出了一种优化时延的方案。该技术方案不仅适用于PoC业务,而且适用于其它对时延敏感的业务,能够大大缩短呼叫建立的时延,将时延缩短到原来的50%左右。

关键词: 无线一键通, TD-SCDMA, 时延, 服务质量

Abstract:

The paper introduces technological background and different technological methods when PoC (push to talk over cellular) is applied to TD-SCDMA system.Based on investigation of different methods,we present an optimal time delay method,which can be extended to other delay-sensitive services.Compared to other methods,the presented method can reduce delay to 50%.

Key words: PoC, TD-SCDMA, delay, quality of service
