Description

一种终端的会话方法、装置及计算机存储介质 技术领域
本发明涉及基于长期演进的语音业务(VoLTE，Voice over Long Term Evolution)领域，尤其涉及一种终端的会话方法、装置及计算机存储介质。
背景技术
随着长期演进(LTE，Long Term Evolution)网络的迅速发展，IP多媒体子系统(IMS，IP Multimedia Subsystem)网络也正在逐步完善，VoLTE的商用进程逐步加快，将逐渐替换固网产品。
在2G/3G网络中，终端既有的呼叫应用程序是通过AT(ATtention)命令进行呼叫发起流程、获取状态等操作的，AT命令是一种调制解调器命令语言。而VoLTE的呼叫流程则是通过IMS/会话初始协议(SIP，Session Initiation Protocol)信令进行的，IMS/SIP协议栈不提供AT命令接口，而是提供应用程序编程接口(API，Application Programming Interface)接口或者消息(Message)接口；为了使终端能够进行VoLTE呼叫流程，现有技术中的解决方案是重新开发出一套VoLTE呼叫应用程序，以适用VoLTE的IMS/SIP信令。而重新开发出的VoLTE呼叫应用程序需要对终端中已应用的呼叫应用程序进行较多修改且对其他关联软件模块引入部分影响，总体改动工作量较大，这就导致不能快速开发出终端中适用于VoLTE的呼叫功能。

工业实用性
本发明实施例的技术方案，呼叫应用功能实体按照既有的呼叫应用程序发送AT命令，呼叫控制服务功能实体接收呼叫应用功能实体发送的第一AT命令后，向IMS网络发送相应的第一SIP消息；接收到IMS网络发送的第二SIP消息后，向呼叫应用功能实体返回相应的第二AT命令。这样由呼叫控制服务功能实体在呼叫应用功能实体与IMS网络之间做AT命令和IMS/SIP消息的适配转换，就可以仍然应用现有的呼叫应用功能实体，使用既有的呼叫应用程序发起呼叫流程。本发明实施例中只需要在主叫终端中增设一个呼叫控制服务功能实体，其他的无需改变，这样可以快速开发出主叫终端中适用于VoLTE的呼叫功能。
