摘要

SIP (Session initiation protocol)是用于VoIP信令和呼叫控制的协议。消息传递和VoIP的计费机制通常用于后付费服务。基于sip的面向公共交换电话网(PSTN)的VoIP呼叫的预付费机制很少被讨论。在本文中，我们提出了一种可以同时处理消息和VoIP呼叫的预付费机制。这种预付机制是在国家电信科技计划(NTP)开发的VoIP平台上实现的。不像以前的VoIP预付方法，需要修改端点，我们的机制可以很容易地集成到VoIP平台，而无需修改现有的网络组件。

Prepaid mechanism of VoIP and messaging services

Session initiation protocol (SIP) is used for voice over IP (VoIP) signaling and call control. Billing mechanisms for messaging and VoIP are typically deployed for postpaid services. Prepaid mechanisms for SIP-based VoIP calls toward public switched telephone network (PSTN) are seldom discussed. In this paper, we propose a prepaid mechanism that can simultaneously process messaging and VoIP calls. This prepaid mechanism is implemented in a VoIP platform developed under National Science & Technology Program for Telecommunications (NTP). Unlike previous VoIP prepaid approaches which require modifications to end points, our mechanism can be easily integrated to a VoIP platform without modifying existing network components.
