    • Embodiments of the present invention relate to a charging method and system for a Push-to-talk over Cellular (PoC) system. The charging method for a PoC system includes: after sending an initial online charging request to an Online Charging System (OCS), receiving an initial online charging response message that is sent by the OCS and carries a downlink channel type switching trigger variable; monitoring a type of a downlink channel used by a PoC service according to the downlink channel type switching trigger variable; and sending an online charging request to the OCS if switching of the type of the downlink channel used by the PoC service is detected, where the online charging request includes a switched type of the downlink channel. The embodiments of the present invention implement precise and proper charging for a PoC client when the PoC client switches a channel.
    • 本发明的实施例涉及一种一键通蜂窝(PoC)系统的计费方法和系统。 PoC系统的计费方法包括:向在线计费系统(OCS)发送初始的在线计费请求后,接收由OCS发送的初始在线计费响应消息,并携带下行链路信道类型切换触发变量; 根据下行链路信道类型切换触发变量来监视PoC业务使用的下行链路信道的类型; 以及如果检测到由PoC服务使用的下行链路信道的类型的切换,则在线计费请求包括切换类型的下行链路信道的情况下,向OCS发送在线计费请求。 当PoC客户端切换信道时,本发明的实施例为PoC客户端实现精确和适当的计费。

    • A Push-to-X over Cellular (PoC) server (351) receives a server registration message (301) for a first called device from a second server. The PoC server (351) receives a PoC invitation message (310) with PoC preferences and a message (313) from an originating device (311). The PoC preferences determine what device to call first (e.g., a mobile device 315, 317) and how many hops the call can be forwarded (e.g., to a voicemail server) if the first-attempted device is not available, before discontinuing the connection. If a trigger, such as time elapsed, occurs for the first-attempted device (350) and the PoC preferences permit, the PoC server (351) sends an invitation message (360) to the second server (391). If the second server (391) is a recording server, the invitation message (360) includes a message (363) from the originating device that is compatible with the capabilities of the recording server (391).
    • Push-to-X over Cellular(PoC)服务器(351)从第二服务器接收用于第一被叫设备的服务器注册消息(301)。 PoC服务器(351)从源设备(311)接收具有PoC偏好和消息(313)的PoC邀请消息(310)。 在停止连接之前,PoC首选项确定首先呼叫什么设备(例如,移动设备315,317)以及如果首次尝试的设备不可用,呼叫可以转发多少跳(例如,到语音邮件服务器) 。 如果首次尝试的设备(350)和PoC偏好设置允许触发(例如时间消逝),则PoC服务器(351)向第二服务器(391)发送邀请消息(360)。 如果第二服务器(391)是记录服务器,则邀请消息(360)包括与记录服务器(391)的能力兼容的始发设备的消息(363)。
