    • A telecommunications system and method for the exchange of standards information facilitates communication by invoking a standards translator whenever two users within the system utilize incompatible communication technologies. In accordance with an embodiment of the present invention, standards information is interchanged between two communications nodes, such that the equipment at those nodes may communicate with each other directly if the same standards are used at both nodes or communicate through the aid of the standards translator when different standards are used. The system and method of the present invention, through the interchange of standards information between the nodes, minimizes communications disruptions caused by mismatched standards.
    • 当系统内的两个用户利用不兼容的通信技术时,用于交换标准信息的电信系统和方法通过调用标准翻译器来促进通信。 根据本发明的实施例,标准信息在两个通信节点之间互换,使得如果在两个节点上使用相同的标准或者通过标准转换器的协助,那些节点处的设备可以直接相互通信 当使用不同的标准时。 本发明的系统和方法通过节点之间的标准信息的交换,最大限度地减少由不匹配的标准引起的通信中断。

    • A method and apparatus for providing a call circuit connection between a mobile station and a remote application host is disclosed. Once a call circuit connection is initially established between a mobile station and remote application host to enable data to transfer therebetween, the call circuit connection is monitored for detection of an idle condition. Upon detection of the idle condition, identifying information for the call circuit connection is stored, and a first portion of the call circuit connection is disconnected while maintaining a second portion of the connection. Upon a request for reconnection of the call circuit connection, the first portion of the call circuit connection is reestablished with the second portion to enable continued data transfer.
    • 公开了一种用于在移动台和远程应用主机之间提供呼叫电路连接的方法和装置。 一旦在移动台和远程应用主机之间最初建立了呼叫电路连接,以使数据能够在其间进行传输,则监视呼叫电路连接以检测空闲状况。 在检测到空闲状况时,存储用于呼叫电路连接的识别信息,并且呼叫电路连接的第一部分在维持连接的第二部分的同时被断开。 在请求重新连接呼叫电路连接时,呼叫电路连接的第一部分与第二部分重新建立,以便能够继续进行数据传送。

    • A method and apparatus are provided for effectuating voice communication between a mobile station and a mobile radio network. A gateway to the mobile radio network receives an incoming voice call for a destination mobile station and accesses information pertaining the status and location of the destination mobile station. A determination is made as to whether the destination mobile station is capable of operation in a voice mode using circuit-switched communications across a traffic channel. If the destination mobile station is operable in the voice mode, a circuit-switched communication on a traffic channel is established between the mobile radio network and the destination mobile station. Otherwise, the incoming voice call is routed to a voice gateway which converts the voice call to data packets and routes the data packets to the mobile station across an Internet Protocol communication network to a packet gateway of the mobile radio network. The packet gateway routes the call across a packet data channel of the mobile radio network to the destination mobile station using a packet data service.
    • 提供一种用于实现移动台和移动无线电网络之间语音通信的方法和装置。 到移动无线电网络的网关接收目的地移动台的进入语音呼叫,并访问与目的移动台的状态和位置有关的信息。 确定目的地移动台是否能够使用跨业务信道的电路交换通信在语音模式下操作。 如果目的地移动台在语音模式下可操作,则在移动无线电网络和目的地移动台之间建立业务信道上的电路交换通信。 否则,进入的语音呼叫被路由到语音网关,语音网关将语音呼叫转换成数据分组,并且将数据分组通过因特网协议通信网络路由到移动台到移动无线电网络的分组网关。 分组网关使用分组数据业务将移动无线电网络的分组数据信道的呼叫路由到目的移动台。
