    • A connection destination determination device includes a control unit for performing an approval determination process to determine that a user authentication state in a connection destination request is approved if the user authentication state satisfies the user authentication state corresponding to a collaboration service. If the user authentication state is determined to be approved in the approval determination process, the control unit responds to a source of the connection destination determination request with the connection destination of service corresponding to the collaboration service which is the search key. If the user authentication state is not determined to be approved in the approval determination process, the control unit responds to the source of the connection destination determination request with the connection destination of authentication service, in order to obtain the user authentication state that does not satisfy the user authentication state corresponding to the collaboration service which is the search key.
    • 连接目的地确定装置包括控制单元,用于执行批准确定处理以确定如果用户认证状态满足与协作服务对应的用户认证状态,则连接目的地请求中的用户认证状态被批准。 如果在批准确定处理中确定用户认证状态被批准,则控制单元使用与作为搜索关键字的协作服务相对应的服务连接目的地来响应连接目的地确定请求的源。 如果在批准确定处理中没有确定用户认证状态被批准,则控制单元用认证服务的连接目的地对连接目的地确定请求的源进行响应,以获得不满足的用户认证状态 与作为搜索关键字的协作服务对应的用户认证状态。

    • A method and a system for speeding up session establishment are provided, wherein the time required to establish a session is reduced, even in the case where a session management server requires a large amount of time to process respective functions required for establishing the session (such as making a decision regarding whether to permit or deny provision of a service, or generating a session key).The session management server is provided with means for conducting, in parallel, processing to issue processing requests for respective functions required for establishing a session (such as making a decision regarding whether to permit or deny provision of a service, or generating a session key) and processing to forward a communication message transmitted by a communications device or another session management server attempting to establish a session.
    • 提供了一种用于加速会话建立的方法和系统,其中即使在会话管理服务器需要大量时间来处理建立会话所需的各种功能的情况下,建立会话所需的时间被减少(例如 作为决定是否允许或拒绝提供服务,还是生成会话密钥)。 会话管理服务器被提供有用于并行处理以发出用于建立会话所需的相应功能的处理请求(例如作出关于是否允许或拒绝提供服务的决定或生成会话密钥)的装置, 以及处理以转发由通信设备或尝试建立会话的另一会话管理服务器发送的通信消息。

    • A streaming data delivery system contrived to curtail the procedure until a session is established between a delivery server and a user terminal includes a delivery device, a server for provisional coupling, format conversion servers, a terminal, and a 3PCC device which implements Third Party Call Control. The 3PCC device obtains format information from the terminal and establishes a session between the terminal and the server for provisional coupling; also obtains data format information from the data delivery device and establishes a session between the delivery device and the server for provisional coupling; further selects a format conversion server, transfers the session between the delivery device and the server for provisional coupling into a session between the delivery device and the selected format conversion server, and transfers the session between the terminal and the server for provisional coupling into a session between the terminal and the selected format conversion server.
    • 设计用于限制该过程直到在递送服务器和用户终端之间的会话建立的流数据传送系统包括传送设备,用于临时耦合的服务器,格式转换服务器,终端和实现第三方呼叫的3PCC设备 控制。 3PCC设备从终端获取格式信息,并在终端和服务器之间建立临时耦合的会话; 还从数据传送装置获取数据格式信息,并在传送装置和服务器之间建立临时耦合的会话; 进一步选择格式转换服务器,将递送设备和服务器之间的会话传送到临时耦合到递送设备和所选择的格式转换服务器之间的会话中,并且将终端与服务器之间的会话传送到会话中 在终端和所选格式转换服务器之间。

    • A data communication system is provided that is capable of increasing or decreasing the number of session management servers flexibly, and is further capable of implementing data communication while distributing the message processing load in the session management server. The data communication system includes multiple communication devices which perform data communications mutually, multiple session management servers which manage sessions of data communication between the communication devices, and a load balancer which assigns the session management servers for processing a message received from the communication device according to a predetermined criterion, wherein, the session management server is provided with a unit for managing a currently logged-in communication device and a state of the communication performed by the communication device, and a unit for acquiring information necessary for performing communication with the communication device.
    • 提供能够灵活地增加或减少会话管理服务器的数量的数据通信系统,并且还能够在会话管理服务器中分发消息处理负载的同时实现数据通信。 数据通信系统包括相互执行数据通信的多个通信设备,管理通信设备之间的数据通信会话的多个会话管理服务器和分配会话管理服务器的负载平衡器,用于处理从通信设备接收的消息,根据 预定标准,其中,会话管理服务器设置有用于管理当前登录的通信设备的单元和由通信设备执行的通信的状态,以及用于获取与通信设备进行通信所需的信息的单元 。
