    • When a calling party calls a called party on the public-switched telephone network (PSTN), a database common to both the PSTN and an Internet Protocol (IP) network, is accessed to determine whether the called telephone line is currently active on the IP network. That database maintains a record for each user who is currently active on the IP network through an Internet Service Provider (ISP). In addition, each record contains information identifying the particular user logged into the network on that line, an indication whether the telephone line is IP telephony capable, an indication whether that line is currently active on an IP telephony call on an Internet Telephony network (ITN), and the IP telephony feature set subscribed to by the called party on that line. If the telephone line is active, IP telephony capable, currently active on an IP telephony call on the ITN, and the called party subscribes to a call waiting-on-IP feature, then the incoming call can be forwarded as an IP telephony call to the called telephone line over the ITN. Alternatively, the incoming call can be directed to an alternate destination on either the ITN network or the PSTN, such as a voice mail or message service. If the called party is engaged in a browsing activity and has an IP telephony capability, then the called party is alerted to the incoming telephone call via a message on his terminal. The incoming call is then completed through the ITN to the called party as an Internet telephony call. If the called party is currently active on the IP network through an ISP, but does not have an IP telephony capability, then the PSTN forwards a message to the ISP, which pushes a message to the called party to inform him or her of the incoming call. The incoming call is then be directed onto the IP network to a messaging service, or on the PSTN to a voicemail service, or to an alternate telephone number, such as a cellular phone, for pickup by the called party.

    • A subscriber to alias telephone number e-mail system can retrieve both their voice-mail messages and e-mail messages by accessing only their e-mail system. Specifically, when a calling party calls the subscriber of an alias e-mail system who is unavailable to take the call, and leaves a voice-mail message on a network-based voice-mail system, the voice-mail system stores the message. The network-based voice-mail system then determines, through a network-based database retrieval, whether the called party is a subscriber to an alias telephone number e-mail system. In such a system, e-mail messages are addressed with a name portion including a subscriber's telephone number. A translation server then translates the alias telephone number e-mail address to the subscriber's actual e-mail address and forwards the message to the subscriber. If the called party is determined to be a subscriber to such a system, the voice-mail system converts the stored voice-mail message into a text or a .WAV file and includes the converted message in an e-mail message addressed to the called party/subscriber's alias telephone number e-mail address for transmission over the Internet. The translation server then converts the alias telephone number e-mail address to the subscriber's actual e-mail address and forwards the e-mail message to the called party/subscriber's e-mail repository server at that actual address for later retrieval by the called party.
    • 别名电话号码电子邮件系统的用户可以仅通过访问其电子邮件系统来检索其语音邮件消息和电子邮件消息。 具体来说,当呼叫方呼叫不可接听呼叫的别名电子邮件系统的用户,并且在基于网络的语音邮件系统上留下语音邮件消息时,语音邮件系统存储消息。 基于网络的语音邮件系统然后通过基于网络的数据库检索来确定被叫方是否是别名电话号码电子邮件系统的订户。 在这样的系统中,电子邮件用包括用户电话号码的名称部分寻址。 翻译服务器然后将别名电话号码电子邮件地址转换成用户的实际电子邮件地址,并将消息转发给用户。 如果被叫方被确定为这样一个系统的用户,则语音邮件系统将存储的语音邮件消息转换为文本或.WAV文件,并将转换的消息包括在寻址到被叫方的电子邮件消息中 方/用户的别名电话号码通过互联网传输的电子邮件地址。 然后,翻译服务器将别名电话号码电子邮件地址转换为用户的实际电子邮件地址,并将该电子邮件消息转发到被叫方/订户的电子邮件存储库服务器,该实际地址供被叫方随后检索 。

    • A mobility support technique provides home agents and foreign agents in mobility aware access networks. Participating mobile hosts are assigned a home address that is used by other hosts as the mobile host's address. The home address actually addresses the home agent provided in the mobility aware access network. The home address provides additional privacy to the mobile host because it does not identify the mobile host's home premises network where the mobile host resides permanently absent any mobility of the mobile host. By providing home agents and foreign agents in a mobility aware access network, the agents may cooperatively establish optimal routing paths for data transmitted to a mobile host. The agents may identify a pseudo home agent, an agent in a mobility aware access network located near to a transmitting mobile host, that acts as the home agent of a destination mobile host. The pseudo home agent tunnels data directly to the destination mobile host without requiring the data to be routed first to the true home agent. In this regard, the pseudo home agent establishes a more direct routing path between the transmitting and destination mobile hosts.
    • 移动支持技术在移动感知接入网络中提供归属代理和外部代理。 参与移动主机被分配一个家庭地址,由其他主机用作移动主机的地址。 归属地址实际上涉及在移动感知接入网络中提供的归属代理。 家庭地址为移动主机提供额外的隐私,因为它不识别移动主机的住宅网络,其中移动主机所驻留的移动主机永远不存在任何移动性。 通过在移动性感知接入网络中提供归属代理和外部代理,代理可以协作地为传送到移动主机的数据建立最佳的路由路径。 代理可以识别充当目的地移动主机的归属代理的伪归属代理,位于发送移动主机附近的移动感知访问网络中的代理。 伪归属代理将数据直接传送到目标移动主机,而不需要首先将数据路由到真正的归属代理。 在这方面,伪归属代理在发送和移动主机之间建立更直接的路由路径。

    • An action control point master gatekeeper for a communications network creates a hierarchical scalable signaling and transaction infrastructure for supporting carrier level deployment of, for example, IP telephony using H.323 terminals and gateways. The action control point master gatekeeper supports a plurality of H.323 zones in an administrative domain. Action control point master gatekeepers in an administrative domain can signal to other administrative domains via a hierarchical signaling infrastructure. A backup master gatekeeper can also be present in an action control point. A customer database, which can be distributed within zones or centralized within an administrative domain, allows for address resolution between a terminal alias and a terminal address. The customer database can also contain pointers to special purpose processes, such as network control points, to implement service specific transaction services.
