摘要： The present invention provides for an improved presence system, which can automatically and unobtrusively factor in the location of a person being monitored when creating presence information for dissemination to subscribers. Presence tags can be distributed at different locations, which may bear on the relative availability of the monitored person for communications. A mobile terminal associated with the monitored person is configured to automatically obtain tag information from the presence tags and deliver location-based state information to the presence server without human interaction. The presence server will process the location-based state information and any other applicable state information to create presence information for the person being monitored, and then deliver the presence information to subscribers.
摘要翻译：本发明提供一种改进的存在系统，其可以在创建用于传播给用户的存在信息时，自动且不引人注目地考虑被监视者的位置。存在标签可以分布在不同的位置，这可能会影响受监控人员的通信的相对可用性。与被监视人相关联的移动终端被配置为从存在标签自动获取标签信息，并且在没有人类交互的情况下将基于位置的状态信息传送到存在服务器。存在服务器将处理基于位置的状态信息和任何其他可应用的状态信息以创建被监视者的呈现信息，然后将呈现信息递送给订户。

摘要： Architecture for normalizing phone numbers and other types of connection information for facilitating mobile communications for users outside their local service areas. When a mobile user attempts to make a connection to a destination entity while outside the user's regular service area, the current location of the user is determined by the system. A normalization rule is selected that corresponds to a local service area associated with the current location. The phone number or other type of connection data string is normalized to the standards of the local service area. The normalized data string is used to automatically complete the connection to the destination entity. In this way, communication is facilitated and simplified for mobile users while traveling abroad.
摘要翻译：用于规范化电话号码和其他类型的连接信息的架构，用于促进本地服务区域之外的用户的移动通信。当移动用户在用户正常服务区域之外尝试连接到目的地实体时，用户的当前位置由系统确定。选择对应于与当前位置相关联的本地服务区域的规范化规则。电话号码或其他类型的连接数据串被标准化为本地服务区域的标准。归一化数据字符串用于自动完成与目标实体的连接。通过这种方式，移动用户在国外旅行时便利和简化通信。

摘要： Techniques to manage presence information are described. An apparatus may comprise a presence management component operative to manage presence information for a presentity node. The presence management component may comprise a presence normalization module operative to retrieve presence temporal information for a home time zone, and normalize the presence temporal information for a local time zone of the presentity node to form normalized presence temporal information. The presence management component may further comprise a presence control module communicatively coupled to the presence normalization module. The presence control module may be operative to send presence state information from the presentity node to a presence server based on the normalized presence temporal information. Other embodiments are described and claimed.

摘要： Network connections that are used in routing VoIP session to their end destination are monitored to determine when a call fails to reach its destination. When a network failure is detected, the call is automatically routed to another device that is not dependent on the failed network connection. The call may be automatically rerouted to one or more secondary numbers, such as a mobile telephone number and/or a PSTN number.
摘要翻译：监控用于路由VoIP会话到其终端目的地的网络连接，以确定呼叫何时到达目的地。当检测到网络故障时，呼叫将自动路由到不依赖于故障网络连接的其他设备。呼叫可以被自动重新路由到一个或多个辅助号码，例如移动电话号码和/或PSTN号码。
