    • The present invention provides a method is provided for soft vertical handovers. The method includes requesting a handover from a first wireless network that operates according to a first protocol to a second wireless network that operates according to a second protocol, the first protocol being different than the second protocol, via a first wireless telecommunication link that operates according to the first protocol. The method also includes forming, in response to the handover request, a second wireless telecommunications link according to the first and second protocols, the second wireless telecommunications link being concurrent with the first wireless telecommunication link. The method further includes dropping the first wireless telecommunications link after forming the second wireless telecommunications link.
    • 本发明提供了一种用于软垂直切换的方法。 该方法包括根据第一协议请求从根据第一协议操作的第一无线网络切换到根据第二协议操作的第二无线网络,第一协议不同于第二协议,经由第一无线电信链路 到第一个协议。 该方法还包括响应于切换请求,形成根据第一和第二协议的第二无线电信链路,第二无线电信链路与第一无线电信链路并发。 该方法还包括在形成第二无线电信链路之后丢弃第一无线电信链路。

    • The present invention provides a method for transmitting voice packet data over a selected one of a first network in which multiple devices belonging to a defined set communicate with each other according to a first protocol and a second network in which multiple devices communicate with each other according to a second protocol, different from the first protocol. The method includes establishing at least one radio bearer between at least two devices in the first network according to the first protocol, receiving at least one voice packet that conforms to the second protocol, modifying the at least one voice packet to conform to the first and the second protocols, and transmitting the at least one modified voice packet using the at least one radio bearer.
    • 本发明提供了一种用于在第一网络中选择的一个网络中传输语音分组数据的方法,其中属于定义集合的多个设备根据第一协议相互通信,并且第二网络中多个设备彼此通信, 到第二协议,不同于第一协议。 该方法包括根据第一协议在第一网络中的至少两个设备之间建立至少一个无线电承载,接收符合第二协议的至少一个语音分组,修改至少一个语音分组以符合第一和第 所述第二协议,以及使用所述至少一个无线承载发送所述至少一个修改的语音分组。
