摘要： Disclosed are a handoff system and a method among heterogeneous networks. The handoff system among heterogeneous networks has plural access nodes which supports wireless communication with a mobile terminal; and a crossover node which selects resources of an access node to which a handoff is made without repetitive communications between access modes and the mobile terminal in selecting an access node. The handoff system performs a handoff to a network if resources of the network are sufficient for wireless communication.
摘要翻译：披露了异构网络中的切换系统和方法。异构网络中的切换系统具有支持与移动终端的无线通信的多个接入节点; 以及交叉节点，其在选择接入节点时，选择进入切换的接入节点的资源，而无需接入模式与移动终端之间的重复通信。如果网络的资源足够用于无线通信，则切换系统执行到网络的切换。

摘要： A handoff system and method between different kinds of devices, an SIP server and an application method of the SIP server applied thereto. The handoff system between different kinds of devices includes a plurality of devices; a SIP server which requests a routing path update when a handoff request signal is input from a source device among the plurality devices, and getting a target device to participate in a current session; and a gateway which updates a predetermined routing path when a request signal for the routing path update is input, and transmitting data to the source device and the target device via the updated routing path.
摘要翻译：不同种类的设备之间的切换系统和方法，SIP服务器和应用于其中的SIP服务器的应用方法。不同种类的设备之间的切换系统包括多个设备; SIP服务器，当从所述多个设备中的源设备输入切换请求信号时请求路由路径更新，并且使目标设备参与当前会话; 以及当输入用于路由路径更新的请求信号时更新预定路由路径的网关，以及经由更新的路由路径将数据发送到源设备和目标设备。

摘要： A method, medium, and apparatus controlling a handover between different network types, including the operations of transmitting a message requesting a transmission bandwidth change, so as to have a transmission bandwidth supported by a new network after movement of the mobile terminal, from the mobile terminal to the server after performing the handover, changing the transmission bandwidth of the server to be supported by the new network based on the transmitted message of requesting the bandwidth change, transmitting a message acknowledging the changed transmission bandwidth from the server to the router, and transceiving data through a new data transmission tunnel between the router and a new access point within the new based on the message acknowledging the changed transmission bandwidth. Accordingly, loss of data packets occuring when a handover is performed may be effectively prevented.
