摘要： A technique for providing real-time multimedia conferencing services with guaranteed performance, in a hybrid networking environment, by interconnecting cable modem-based premises networks via hybrid fiber coaxial (HFC) access networks and an ATM wide area network is disclosed. The ATM wide area network may be divided into a plurality of access network domains and one backbone network domain to provide efficient and intelligent multimedia conferencing services. Each ATM access network domain has one cable modem server as well as access multimedia bridge server. There is only one central network server and one central multimedia bridge server within the backbone network domain. Each cable modem server located in an ATM access network domain maintains necessary information of how the cable network bandwidth is used by existing calls, and will be allocated when new multimedia conference calls are initiated, in accordance with desired priority and performance levels.
摘要翻译：公开了一种在混合网络环境中通过混合光纤同轴（HFC）接入网络和ATM广域网互联基于电缆调制解调器的房屋网络来提供具有保证性能的实时多媒体会议业务的技术。 ATM广域网可以分为多个接入网域和一个骨干网域，以提供高效智能的多媒体会议业务。每个ATM接入网域都有一个电缆调制解调器服务器以及接入多媒体桥服务器。骨干网域内只有一台中央网络服务器和一台中央多媒体网桥服务器。位于ATM接入网域中的每个电缆调制解调器服务器保持有关现有呼叫如何使用有线网络带宽的必要信息，并且将根据期望的优先级和性能水平在新的多媒体会议呼叫被启动时被分配。

摘要： A method for communication employs a plurality of gatekeepers and involves receiving at a first gatekeeper a request for information. If the information is not known by the first gatekeeper, a request is sent via a second gatekeeper to a third gatekeeper for the information. If the information is known by the third gatekeeper, it is returned to the first gatekeeper, illustratively via the second gatekeeper. The gatekeepers are at a single gatekeeper hierarchical level.

摘要： The present invention provides a method and system for assuring H.323 alias address portability to an H.323 user in real-time H.323 multimedia communications where the H.323 user is registered with a home gatekeeper for the home zone of the H.323 user. Alias address portability may be obtained using a central database that is known to the administrative zones and is used for alias address mapping, or alternatively, may be obtained by using a distributed database. The method may be implemented by: sending, by the H.323 user, a message with a called H.323 entity's alias address, to the home gatekeeper to originate a call to the called H.323 entity; confirming that the alias address, services, and service providers are portable; converting the alias address to a called routable alias address for the called H.323 entity and sending the alias address to the H.323 user; and placing the call to the called H.323 entity.
摘要翻译：本发明提供一种方法和系统，用于在实时H.323多媒体通信中向H.323用户确认H.323别名地址可携带性，其中H.323用户向H的本地用户注册H .323用户。可以使用管理区域已知的并用于别名地址映射的中央数据库获取别名地址可移植性，或者可以通过使用分布式数据库获得别名地址可移植性。该方法可以通过以下方式来实现：由H.323用户将具有被叫H.323实体的别名地址的消息发送到归属关守以发起对被叫H.323实体的呼叫; 确认别名地址，服务和服务提供者是可移植的; 将别名地址转换为被叫H.323实体的被叫可路由别名地址，并将别名地址发送给H.323用户; 并将呼叫发送到被叫H.323实体。

摘要： An interworking function (IWF) for a first and second protocol based network, for example, an H.323 protocol based network and an SIP protocol based network comprises an interworking gateway server including a state machine for defining each call processing state and a translation table for use in translating addresses formatted in each protocol. A method of interworking for use in interworking between said first protocol based network and said second protocol based network comprises the steps of receiving at said interworking gateway server serving said first and second protocol based networks a request from an endpoint in the first or second protocol based networks, establishing a state machine in memory whereby, for each state of said state machine, a message associated with that state is categorized as one of a triggering message, a non-triggering message and an error message, establishing a translation table in said memory whereby an address formatted in said first protocol has a one-for-one correspondence with an address formatted in said second protocol, processing said request in accordance with said translation table and said state machine and permitting communication between said first and second endpoints utilizing a realtime transport protocol. In the event media is terminated at said interworking gateway server, the interworking gateway server, in one embodiment, comprises a media switching fabric for switching media terminated at the gateway to an addressed endpoint capable of receiving it.

摘要： A method for providing real-time multimedia conferencing services is described over a hybrid network, consisting of packet-switched nonguaranteed quality of service local area networks and a cell-switched wide area network having a multimedia bridge connected to the wide area network. The local area networks and the multimedia bridge are interconnected to the wide area network via routers. New architectural entities within the multimedia bridge execute a multimedia performance and resource analysis algorithm and determine whether the network and the bridge have sufficient resources to satisfy the requirements of the multimedia conference call. If sufficient resources are not available, it is determined whether the requirements for the higher priority services can be provided by preempting the lower priority resources. Signaling information messages are exchanged between the communicating entities indicating whether the multimedia conference can be accepted, rejected, or accepted to operate in degraded mode, based on the analysis performed by the bridge.

摘要： A customer premises border element is disclosed that functions as an interface between devices, such as SIP devices located on a customer's premises, and a border element located in the service provider's network. Such customer premises border elements are advantageous in that they are relatively inexpensive since they only have to support devices located on the customer's premises. At the same time, by performing a number of functions, such as media transcoding and a portion of call processing, it reduces the processing requirements of network border elements.
