摘要
根据SIP系统的组成结构,利用SER和PJSIP在普通呼叫业务的基础上开发会话转移业务,包括确定的会话转移(As-sured Transfer,也称Unattended Transfer)和需要协商的会话转移(Consultive Transfer,也称Attended Transfer)。实验结果证明,会话转移业务具有较高的实用及研究价值。
According to the SIP architecture,this paper mainly talks about the design and implementation of the session transfer service.Based on the general call service,the Assured Transfer and the Consultive Transfer is developed here,using SER and the open source SIP stack PJSIP.Experiment result shows that the SIP-based session transfer service values highly in our daily life and the research field.
