    • PURPOSE: A hand-off method in a domain of an MIP(Mobile Internet Protocol) communication network is provided to designate an area managed by a domain server as one domain so that an authentication about a mobile subscriber is not performed in a home network when an FA(Foreign Agent) is changed in one domain. CONSTITUTION: A temporal tunnel is set up between the second FA(43) and the first FA(42) according as an FA is changed to not the first FA(42) in which connection is set up in one domain but the second FA(43) by the movement of a mobile subscriber(41)(416). The second FA(43) updates visitor information through an HA(Home Agent)(46) of a home network and transmits updated visitor information to the mobile subscriber(41)(421). The temporal tunnel is released between the first FA(42) and the second FA(43)(422). The first FA(42) ends the connection with an area domain server(423,424).
    • 目的:提供MIP(移动因特网协议)通信网络域中的切换方法,以将由域服务器管理的区域指定为一个域,使得在家庭网络中不执行关于移动用户的认证, FA(外地代理)在一个域中更改。 构成:根据FA改变为第一FA(43)和第一FA(42)之间的时间隧道而不是在一个域中建立连接的第一FA(42),而第二FA( 43)通过移动用户(41)的移动(416)。 第二FA(43)通过家庭网络的HA(归属代理)(46)更新访客信息,并将更新的访问者信息发送到移动用户(41)(421)。 时间通道在第一FA(42)和第二FA(43)(422)之间释放。 第一个FA(42)结束与区域域服务器的连接(423,424)。

    • PURPOSE: A method for controlling a call in a digital mobile communication network radio data interlocking device is provided to increase the reliability of a service by retransmitting data lost in case that data transmitted between a radio data terminal of a subscriber and a radio data communication interlocking device according to a deterioration or a hand-off of a radio section. CONSTITUTION: In case that a mobile subscriber tries to call, a mobile terminal starts to call. A mobile communication exchange makes a request for setting a call to a radio data communication interlocking device(301). The radio data communication interlocking device determines whether a mobile subscriber originating call or a terminating call using the number of a trunk(302). The interlocking device selects efficient resources using an INWA board(303). The interlocking device activates a pair of modems and a speed matching device(304). The device initializes the state of the modems(305). The device generates one socket for exchanging information with a protocol stack module(306). The device judges the type of the call(307). In case of the originating call, the device performs a passive open of a TCP(308). In case of the terminating call, the device performs an active open of the TCP(313).
    • 目的:提供一种用于控制数字移动通信网络无线电数据互锁装置中的呼叫的方法,用于通过在用户的无线电数据终端和无线电数据通信互锁之间传输的数据的情况下重传丢失的数据来增加服务的可靠性 根据无线电部分的恶化或越区切换的装置。 规定:如果移动用户尝试呼叫,则移动终端开始呼叫。 移动通信交换机请求设置对无线电数据通信互锁装置(301)的呼叫。 无线电数据通信互锁装置使用中继线(302)的号码确定移动用户发起呼叫或终止呼叫。 联锁装置使用INWA板选择有效的资源(303)。 互锁装置激活一对调制解调器和速度匹配装置(304)。 设备初始化调制解调器的状态(305)。 设备生成一个用于与协议栈模块交换信息的套接字(306)。 设备判断呼叫的类型(307)。 在发起呼叫的情况下,设备执行TCP的被动打开(308)。 在终止呼叫的情况下,设备执行TCP(313)的主动打开。

    • PURPOSE: A method for controlling a data service in a mobile exchange is provided to configure a wireless data service IWF(Inter Working Function) as a gadget of the mobile exchange, and to make the mobile exchange control the IWF. CONSTITUTION: If an idle MS(Mobile Station)(10) requests asynchronous data or a fax service, an MX(Mobile EXchange)(40) checks whether a calling subscriber is capable of calling and checks a called subscriber number. If the number is located in a local station, the MX(40) performs a paging and checks service options of the calling and a called subscriber. If the two subscribers request the asynchronous data or the fax service, the MX(40) starts a data service local call processing. If the called subscriber is registered in other exchange, the MX(40) occupies an outgoing trunk. If the service option of the calling subscriber requests the asynchronous data or the fax service, the MX(40) starts a data service outgoing call. The MX(40) occupies a wireless data communication IWF(Inter Working Function)(100) to connect a speech path, and transmits a response of a called control station to the IWF(100) and a calling control station, then starts a data service billing. If the MX(40) receives a response from a called exchange, the MX(40) transmits the response to the IWF(100) and the calling control station, then starts a data service billing. If a hand off is generated during a busy state, the MX(40) changes the speech path. If an additional service is requested, the MX(40) ignores the request. If a subscriber cuts off the speech path, the MX(40) performs a data service cancellation processing.
    • 目的:提供一种用于控制移动交换机中的数据服务的方法,将无线数据业务IWF(Interwork Function)作为移动交换机的小配件配置,并使移动交换机控制IWF。 规定:如果空闲MS(移动台)(10)请求异步数据或传真服务,则MX(移动交换)(40)检查主叫用户是否能够呼叫并检查被叫用户号码。 如果该号码位于本地站,则MX(40)执行寻呼并检查呼叫和被叫用户的业务选项。 如果两个订户请求异步数据或传真服务,则MX(40)启动数据服务本地呼叫处理。 如果被叫用户以其他交换机注册,则MX(40)占据出站中继线。 如果主叫用户的服务选项请求异步数据或传真服务,则MX(40)启动数据业务传出呼叫。 MX(40)占用无线数据通信IWF(InterWork Function,互联功能)(100)来连接语音路径,并将被叫控制站的响应发送到IWF(100)和呼叫控制站,然后启动数据 服务计费。 如果MX(40)从被叫交换机接收到响应,则MX(40)向IWF(100)和主叫控制台发送响应,然后启动数据业务计费。 如果在繁忙状态下产生切换,则MX(40)会改变语音路径。 如果请求附加服务,MX(40)将忽略该请求。 如果用户切断语音路径,则MX(40)执行数据服务取消处理。
