Description

一种MCPTT架构下控制信令传输方法以及相关设备 技术领域
本发明涉及通信领域，尤其涉及一种关键任务集群通信(Mission Critical Push To Talk，MCPTT)架构下控制信令传输方法以及相关设备。
背景技术
目前无线集群技术在不同行业有着广泛的应用，且随着无线技术尤其是长期演进(Long Term Evolution，LTE)技术的飞速发展，LTE宽带集群逐渐成为无线集群业务未来发展的方向。在LTE宽带集群业务流程中，策略和计费控制是一个非常关键的环节。
其中，目前的策略和计费控制环节中，应用服务器对LTE网络进行策略和计费控制都是通过LTE网络中的策略和计费规则功能(Policy and Charging Rule Function，PCRF)实体的通用的Rx接口完成。其中，3GPP架构下，PCRF实体的Rx接口面向的是作为AF(Application Function)应用功能的通用的IP多媒体子系统(IP Multimedia Subsystem，IP多媒体子系统，IMS)/会话初始协议(Session Initial Protocol，SIP)核心网络层。这样当应用服务器需要与PCRF进行用于策略和计费的控制信令传输时，这些用于策略和计费的控制信令都需要经过IMS/SIP核心网络层进行转发的。例如：针对MCPTT业务，MCPTT应用服务器需要向PCRF传输用于策略和计费的控制信令时，MCPTT需要将该用于策略和计费的控制信令传输至IMS/SIP组网，IMS/SIP组网再将该用于策略和计费的控制信令传输给PCRF，同理，PCRF向MCPTT传输用于策略和计费的控制信令时，也是需要经过IMS/SIP组网进行中转。另外，在一些场景中PCRF与MCPTT应用服务器之间没有部署MS/SIP组网，这样在该场景中PCRF与MCPTT应用服务器之间没无法进行用于策略和计费的控制信令的传输。可见，现有技术中PCRF与MCPTT应用服务器可能会存在用于策略和计费的控制信令无法传输或者传输的效率低的问题。

202、PCRF实体使用所述连接通道与所述MCPTT应用服务器传输用于策略和计费的控制信令。
当步骤201建立上述连接通道后，PCRF实体就可以通过该连接通道与上述MCPTT应用服务器进行用于策略和计费的控制信令的传输。其中，这里的用于策略和计费的控制信令的传输可以是，上述PCRF实体接收上述MCPTT应用服务器发送的用于策略和计费的控制信令，或者可以是上述PCRF实体向 上述MCPTT应用服务器发送用于策略和计费的控制信令。另外，本发明实施例中上述用于策略和计费的控制信令包括但不限于：策略和计费请求信令、策略和计费响应信令或者策略和计费通知信令等PCRF实体与应用服务器之间需要传输的用于策略和计费的控制信令。

本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存取存储器(Random Access Memory，简称RAM)等。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
