Abstract: A handover method in a mobile communication network and the mobile terminal using the same are provided to supply mobile communication network services having performance and cost suitable for a user's request. A comparison unit checks whether received signal strength of a currently accessed wireless network cell is stronger than the first threshold value(310). The comparison unit checks whether signal strength of new wireless network cells is stronger than the second threshold value(320). The first data transceiver transmits RSSI(Received Signal Strength Intensity) information about wireless network cells having strength stronger than the second threshold value to the first base station(330).

Abstract: A handover method in an IP-based radio network is provided to enable a terminal to receive an IP in an IP management area, and keep an IP address regardless of the movement of the terminal when there is a session performed by the terminal, thereby performing the handover of the terminal without changing the IP address of the terminal to prevent a delayed time and a data loss. A PSS(Portable Subscriber Station)(101) reports a radio access status to a RAS(Radio Access System)(102)(S401). The PSS requests a new RAS(105) to perform the handover of the terminal(S402). The new RAS determines whether to receive the terminal and transmits a handover response to a previous RAS(S403). The previous RAS sets a data path to the new RAS during handover and prevent a loss of data during the handover(S404). The previous RAS directs the PSS to perform handover(S405). The PSS performs a radio access connection with the new RAS(S406). The new RAS completes the radio access connection with the PSS(S407). The new RAS sets a radio data path to the PSS(S408). The new RAS notifies a radio access gateway(103) that the PSS is registered in itself(S409). The radio access gateway processes a registration request, releases the data path of the PSS through the previous RA, and sets the data path of the PSS through the new RAS(311,S411). Accordingly, an IP(Internet Protocol) bearer path to the PSS is completed.
Abstract translation: 提供了一种基于IP的无线网络中的切换方法，使得终端能够在IP管理区域中接收IP，并且在终端执行会话时不考虑终端的移动来保持IP地址，从而执行 终端的切换，而不改变终端的IP地址，以防止延迟时间和数据丢失。 PSS（便携式用户站）（101）向RAS（无线接入系统）（102）报告无线接入状态（S401）。 PSS请求新的RAS（105）执行终端的切换（S402）。 新的RAS确定是否接收终端并向先前的RAS发送切换响应（S403）。 先前的RAS在切换期间设置到新RAS的数据路径，并防止在切换期间丢失数据（S404）。 先前的RAS指示PSS执行切换（S405）。 PSS使用新的RAS执行无线接入连接（S406）。 新RAS完成与PSS的无线接入连接（S407）。 新的RAS设置到PSS的无线电数据路径（S408）。 新RAS向无线接入网关（103）通知PSS本身注册（S409）。 无线电接入网关处理注册请求，通过先前的RA释放PSS的数据路径，并通过新的RAS（311，S411）设置PSS的数据路径。 因此，完成了到PSS的IP（因特网协议）承载路径。

Abstract: A system and a method for supporting user and service mobility in a ubiquitous environment are provided to enhance user satisfaction and convenience in service mobility by determining an optimum service device based on characteristic information of a user and a service. A domain server(410) authenticates a user who enters the second network by interworking with the first network, controls the movement of a service based on user location information, user situation information and service situation information, and determines one of plural service devices. A media adaptation server(420) converts data of the service in order to provide the service to a service device determined by the domain server(410). A location recognition server(440) senses location of the user and provides the sensed result as physical location information. A location management server(430) receives physical location information of the user from the location recognition server(440), recognizes it as logical location information to thus manage location information of the user, and provides location information of the user to the domain server(410).

Abstract: A system and a method for managing service shift are provided to manage the service shift by selecting a service terminal for offering a service to a user based on user profile information including user movement information and service shift selection information of the user. Each service terminal(100,110) detects movement of the user by recognizing a tag including ID information and transfers user ID information to a service shift manager(130). A user terminal(120) transfers the service shift selection information received from the user terminal to the service shift manager. The service shift manager selects the terminal for offering the service to the user based on the user profile information. The user profile information includes the user ID information received from the service terminals and the service shift selection information received from the user terminal. The service shift manager transfers a user logon message to the selected terminal and transfers a user logoff message to the terminal shifting the service. The terminal receiving the user logon message starts the service.

CONSTITUTION: A mobile terminal(10) is within a scope of an optional base station(20). The information of the mobile terminal(10) is transmitted to a mobile exchange(40) through base stations(20) and base station controllers(30) for controlling the base stations(20). The information transmitted from the mobile exchange(40) is transmitted to the mobile terminal(10) for receiving a mobile communication service through the base stations(20) and the base station controllers(30) for controlling the base stations(20).

Abstract: PURPOSE: A method for controlling a CODEC of a mobile terminal for a circuit switched service in an asynchronous IMT-2000 system is provided to obtain a mobility management connection for an originating call, and to indicate CODEC function activation with a CODEC module, thereby securing voice and video calls. CONSTITUTION: A call control protocol waits until a call setup request is received(S301). If the call setup request is received(S302), the protocol obtains call setup targeted service information(S303) and obtains a mobility management connection for an originating call(S304). The protocol requests CODEC function activation of a CODEC module(S305), and starts a response standby timer for the CODEC function activation(S306). The protocol waits whether a CODEC function activation response is received from the CODEC module(S307). If not, and if the response standby timer expires(S311), the protocol performs a canceling procedure for the mobility management connection(S312), and sets a CODEC operation mode to 'Fail'(S313). The protocol informs a user that a call is not set, and completes the procedure(S314).
