摘要： The method provides for a first network controller, operating according to a first radio technology, to form and send a relay message to a second network controller, operating according to a different, second radio technology. The relay message includes an embedded message for the second network controller. The embedded message may be a transition message requesting transition of a packet switched call for a mobile station handled by the first network controller to a call for the mobile station handled by the second network controller. The method further provides selection of another wireless element for service at a wireless unit, using a current wireless element. A wireless unit receives a message identifying at least one other wireless element, available to the wireless unit and to which a wireless element currently in communication with the wireless unit is also in communication with and the wireless unit selects another wireless element for possible future service based on the message.

摘要： The present interoperability system serves to pass presence and supervision information relating to a user's wireless station set between a cellular communication network and an enterprise communication network, which typically includes a Private Branch Exchange system. The interoperability system functions to extend the wireless Private Branch Exchange services provided in the enterprise communication network to the cellular communication network based on the presence and supervision data provided by the interoperability system. The provision of ubiquitous service to the user, regardless of their location provides a significant advantage over existing Private Branch Exchange and cellular communication network services. In addition, the user is equipped with only one wireless station set, which can operate as a cordless Private Branch Exchange extension in the office or as a standard wireless station set outside of the office.

摘要： A telecommunication system routes wireless-specific digital frames from a first wireless communication device across a data-oriented network, without vocoding, for information delivery to a second communication device while implementing multi-party conferencing and tone/announcement generating functionality. Tone and announcement generation services are provided while the call path retains the wireless-specific digital frame format between the first wireless communication device and the terminating gateway. When tones are generated by the first wireless communication device, signaling messages are sent directly to the terminating gateway vocoder to initiate the generation of full rate DTMF tones at the terminating network. When tones and announcements are sent to the first wireless communication device, a resource server, working together with a feature server, generates a wireless-encoded version of the tone or announcement. This wireless-encoded version is then sent to the first wireless communication device, where an audible version of the tone or announcement is produced. When multi-party conferencing is initiated, the first call is established via wireless-specific digital frame communication. The first call is placed on hold while the second call is completed using a digital wireline format (e.g., PCM). Through vocoding, the first call's connection is re-negotiated to match the digital wireline format of the second call. To complete the conference call, the two calls are combined in the conference circuit as a composite digital wireline traffic stream.
摘要翻译：电信系统通过面向数据的网络将无线特定的数字帧跨越面向数据的网络路由，而无需声码，用于在实现多方会议和音调/通告生成功能的同时向第二通信设备发送信息。在呼叫路径保持第一无线通信设备和终接网关之间的无线特定数字帧格式的同时提供音调和通知生成服务。当由第一无线通信设备生成音调时，信令消息被直接发送到终端网关声码器，以在终端网络发起全速率DTMF音的产生。当音调和通知被发送到第一无线通信设备时，与特征服务器一起工作的资源服务器产生无线编码版本的音调或通知。然后，该无线编码版本被发送到第一无线通信设备，其中产生音调或通知的可听版本。当多方会议启动时，首先通过无线特定的数字帧通信建立呼叫。当使用数字有线格式（例如，PCM）完成第二个呼叫时，第一个呼叫被置于保持状态。通过声码，第一呼叫的连接被重新协商以匹配第二呼叫的数字有线格式。要完成电话会议，两个呼叫在会议电路中组合为复合数字有线业务流。

摘要： The present invention provides methods of inter-technology handoff of a multi-mode mobile unit in a packet-switched communication system. One embodiment of the method includes establishing a call from a first application layer client in the first mobile unit using a first wireless communication link that operates according to a first wireless access technology. The method also includes sending, in response to detecting changing conditions of the first wireless communication link, a request to form a conference call including the first application layer client and inviting a second application layer client in the first mobile unit to join the conference call. The second application layer client uses a second wireless communication link that operates according to a second wireless access technology. The method further includes handing off the call from the first application layer client to the second application layer client.

摘要： The present invention provides a method for detecting bearer loss in an IP-based multimedia session. A multimedia session is initiated by an access terminal. A Policy and Charging Rules Function (PCRF) communicates the Session setup information and the bearer characteristics to a Signaling Gateway (SGW). The SGW uses this information to adjust the dormancy timers on the originating side so that the originating access link remains active during the call setup.
