摘要

在线服务是IP多媒体子系统(IMS)中最重要的业务之一，它允许用户表达自己的可用性和相互通信的意愿。一些研究表明，呼叫会话控制功能(Call Session Control Function, CSCF)可能成为IMS网络中的瓶颈，但是当关键的IMS服务存在服务(PS)与web服务(WS)结合时，瓶颈的数量可能发生变化或转移到其他节点。本文给出的仿真结果表明，当PS和WS结合使用时，AS和WS可能成为性能瓶颈。将仿真结果与理论分析结果进行了比较，结果与理论分析结果吻合较好。本文提出了一种提高性能和消除瓶颈的解决方案。

Bottlenecks elimination and performance enhancements in IMS presence service

Presence service is one of the most important IP Multimedia Subsystem (IMS) services which allow the user to express their availability and willingness to communicate with each other. Several studies have shown that Call Session Control Function (CSCF) may become the bottleneck in the IMS network, but when a crucial IMS service presence service (PS) is combined with the web services (WS), the number of bottlenecks may change or may shift to some other node. In this paper, simulation results have been presented which shows that when PS and WS are combined together then AS and WS may become the performance bottlenecks. The simulation results are then analyzed and compared with the theoretical analysis and they show a good agreement with it. A solution to improve the performance and to eliminate the bottlenecks has been suggested through this paper.
