    • For an incoming session intended for a user element, a domain selection function (DSF) is provided in a multimedia subsystem (MS) to select a circuit-switched subsystem (CS) or MS domain to use when routing the incoming session to the user element. Regardless of the domain in which incoming sessions are originated, the incoming sessions intended for the user element are routed to an S-CSCF in the MS. The S-CSCF directly or indirectly employs the DSF to determine whether to use the MS or the CS for terminating the incoming session. Based on available domain selection criteria, the DSF will select an appropriate domain, such as the MS or CS, to use for routing the incoming session to the user element. The domain selection decision of the DSF is provided to the S-CSCF, which will proceed by routing the incoming session to the user element via the selected domain.
    • 对于用于用户元素的传入会话,在多媒体子系统(MS)中提供域选择功能(DSF),以选择在将传入会话路由到用户元素时使用的电路交换子系统(CS)或MS域 。 不管发起传入会话的域名,用于用户元素的传入会话路由到MS中的S-CSCF。 S-CSCF直接或间接地使用DSF来确定是否使用MS或CS来终止传入会话。 基于可用的域选择标准,DSF将选择适当的域,例如MS或CS,用于将传入会话路由到用户元素。 DSF的域选择决定被提供给S-CSCF,S-CSCF将通过所选择的域将入局进入路由到用户单元。

    • The present invention provides a call/session control function for an Internet Protocol multimedia subsystem where a service template may be invoked in lieu of a single multimedia service. The service template identifies a number of multimedia services and associated logic for invoking the multimedia services, once the service template is invoked. In operation, a signaling message is received and appropriate filtering criteria are retrieved for the signaling message. Filtering criteria define a set of rules identifying any multimedia services that need to be invoked in light of receiving the signaling message. The filtering criteria will identify a service template, and perhaps other multimedia services to invoke directly. If a service template is invoked, the service template is obtained and the logic controlling invocation of the associated multimedia services is applied to effect invocation of the multimedia services.
    • 本发明提供了一种用于互联网协议多媒体子系统的呼叫/会话控制功能,其中可以调用服务模板来代替单个多媒体服务。 一旦调用了服务模板,服务模板就会识别多个多媒体服务和相关联的逻辑来调用多媒体服务。 在操作中,接收到信令消息,并为信令消息检索适当的过滤标准。 过滤标准定义了一组根据接收到信令消息而需要调用的多媒体业务的规则。 过滤标准将识别服务模板,以及可能直接调用的其他多媒体服务。 如果调用了服务模板,则获得服务模板,并且应用相关联的多媒体服务的逻辑控制调用来实现多媒体服务的调用。

    • Provided is a method and system for providing a packet-based multimedia service to a mobile device in a network. The service is defined by a telecommunications standard, such as the 3GPP IP multimedia subsystem (IMS) standard, and the network does not support packet quality of service (QoS) functionality as required by the standard. A communications session embodying the method may be initiated by the mobile device or by the network. The method begins by establishing simultaneous packet signaling and circuit bearer connections with the mobile device. Signaling information for the multimedia service may then be transferred via the packet signaling connection using a session initiation protocol (SIP) or similar protocol. Data for the multimedia service may be transferred via the circuit bearer connection. This enables a feature rich signaling protocol to be used to provide the multimedia service via the network in alignment with the standard, even though the network does not support the required QoS functionality.
    • 提供了一种用于向网络中的移动设备提供基于分组的多媒体服务的方法和系统。 该服务由诸如3GPP IP多媒体子系统(IMS)标准的电信标准定义,并且该网络不支持标准所要求的分组服务质量(QoS)功能。 体现该方法的通信会话可以由移动设备或网络启动。 该方法通过与移动设备建立同时的分组信令和电路承载连接开始。 然后可以使用会话发起协议(SIP)或类似协议经由分组信令连接来传送用于多媒体服务的信令信息。 多媒体业务的数据可以通过电路承载连接传输。 这使得能够使用特征丰富的信令协议来提供与标准一致的网络的多媒体服务,即使网络不支持所需的QoS功能。

    • A packet-based multimedia service is provided to a terminal in a network. A packet signaling connection is established between the terminal and the network. Signaling information for the multimedia service is transferred via the packet signaling connection using Session Initiation Protocol (SIP) or a similar protocol. A circuit bearer connection is also established with the terminal. Data for the multimedia service is transferred via the circuit bearer connection. This allows the data to be carried across networks which do not support the required QoS functionality for the packet-based service, or which cannot efficiently carry packet-based data. The circuit bearer connection can be established by a network entity or by the terminal. The circuit bearer can be interworked to a packet-switched bearer at some point in the network, such as at a gateway, so as to provide a remote party with the appearance that a fully packet-switched connection is being used.
    • 基于分组的多媒体服务被提供给网络中的终端。 在终端和网络之间建立分组信令连接。 通过使用会话发起协议(SIP)或类似协议的分组信令连接来传送多媒体业务的信令信息。 终端也建立了电路承载连接。 通过电路承载连接传输多媒体业务的数据。 这允许数据在不支持基于分组的服务所需的QoS功能的网络上承载,或者不能有效地承载基于分组的数据。 电路承载连接可由网络实体或终端建立。 电路承载可以在诸如网关的网络中的某一点处与分组交换承载互通,从而向远程方提供正在使用完全分组交换连接的外观。
