    摘要:

    基于电路交换的传统电话录音系统因其结构复杂,存储的不便捷和非实时性的特点,已经无法满足新时代行政办公对高效,即时的通话录音需求,因此,提出一种基于电力IMS的电话实时录音系统.首先分析了电力IMS交换网中电话终端实时录音的业务需求;其次介绍了系统的实现流程,阐明了系统的关键技术:利用录音服务器对其镜像端口的SIP报文进行解析获得媒体流并解码、采用一致性哈希算法的内存数据库作为解码数据的缓存机制、利用Ckafka技术在两者之间构建实时数据通道;最后就响应时间、吞吐量、容错能力和推送的最大时延这四项指标对录音服务器进行性能分析,结果表明该系统的实时性强,吞吐量大,具备一定的容错能力,并能实现多服务器之间的负载均衡.

    Abstract:

    The traditional circuit-switched telephone recording system has been unable to meet the needs of efficient and instant call recording in the new era administrative office due to its complicated structure, inconvenient storage, and non-real-time characteristics. Therefore, this paper presents a real-time recording system for power IMS telephone terminal to solve these problems. First of all, the article analyzes the business needs of real-time recording of telephone terminals in the power IMS exchange network. Secondly, the article introduces the implementation process of the system and clarifies the key technologies of the system: the system uses the recording server to parse the SIP message of its mirrored port for obtaining the media stream and decoding, and consistent Hash algorithm memory database is used as decoding data caching mechanism, and the message queue between the both is Ckafka. Finally, the performance of the recording server is analyzed based on the four indicators of response time, throughput, fault tolerance, and maximum delay. The analysis shows that the system has strong real-time performance, large throughput, certain fault tolerance, and load balancing.
