    • One embodiment of the present invention facilitates efficient metering in a packet network environment by providing a single metering message, which contains sufficient information to provide the complete call tariff model for a particular call. The media gateway receiving the message can analyze the information provided in the message to determine how to provide metering pulses for all phases of the call, as well as any one-time charges, such as setup and add-on charges. Another embodiment of the invention provides a way for handling fractional pulse counts in an efficient manner. Yet another embodiment facilitates the handling of situations where charge intervals do not divide evenly into the phase duration of the phase associated with the call. In still another embodiment, the amount of information necessary to deliver the parameters of the call tariff model is minimized to reduce the overhead necessary for facilitating the metering process.
    • 本发明的一个实施例通过提供单个测量消息来提供分组网络环境中的有效计量,该测量消息包含足够的信息以为特定呼叫提供完整的呼叫费率模型。 接收消息的媒体网关可以分析消息中提供的信息,以确定如何为呼叫的所有阶段提供计量脉冲,以及任何一次性费用,例如设置和附加费用。 本发明的另一个实施例提供了一种以有效的方式处理分数脉冲计数的方法。 另一个实施例有助于处理充电间隔不均匀地划分到与呼叫相关联的相位的相位持续时间的情况。 在另一个实施例中,将呼叫资费模型的参数传递所需的信息量减到最小以减少便于计量过程所需的开销。

    • The present invention allows a network policy server or other centralized entity to provide arbitration for selecting media capabilities to use in a communication session between communication clients. In operation, the network policy server will directly or indirectly receive a first message in association with an attempt to establish a communication session from a first communication client. The first message will include the available media capabilities of the first communication client. The network policy server will apply appropriate policies for the first communication client, the network in general, or a combination thereof to select one or more of the first media capabilities to determine a second set of media capabilities, which are provided in response to the first message. This reduced set of media capabilities will ultimately be used to establish the communication session with the first communication client.
    • 本发明允许网络策略服务器或其他中央实体提供仲裁以选择在通信客户​​端之间的通信会话中使用的媒体能力。 在操作中,网络策略服务器将直接或间接地接收与第一通信客户端建立通信会话的尝试相关联的第一消息。 第一个消息将包括第一个通信客户端的可用媒体功能。 网络策略服务器将对第一通信客户端,一般的网络或其组合应用适当的策略,以选择一个或多个第一媒体能力来确定第二组媒体能力,其响应于第一通信客户端 信息。 这种减少的媒体功能集最终将用于建立与第一通信客户端的通信会话。
