    • The present invention relates to a vertical handoff method. According to the present invention, a serving network of a mobile station is determined. Herein, the mobile station that can access a first network having relatively wide service coverage and a second network having relatively narrow service coverage in an area where service coverages of heterogeneous networks are overlapped. When accessing the serving network of the first network, it is determined whether a received signal strength received from the second network is greater than a first threshold value. In addition, a first vertical handoff is decided by using a result of prediction of a transition pattern of the received signal strength that is greater than the first threshold value. When the serving network is the second network, it is determined whether the received signal strength received from the second network is less than a second threshold value. By using a result of prediction of a transition pattern of the received signal strength that is less than the second threshold value, a second vertical handoff is decided. Herein, the first threshold value is greater than the second threshold value.
    • 本发明涉及垂直切换方法。 根据本发明,确定移动台的服务网络。 这里,可以访问具有相对较宽服务覆盖范围的第一网络的移动站和在异构网络的服务覆盖区域重叠的区域中具有相对窄的业务覆盖的第二网络。 当访问第一网络的服务网络时,确定从第二网络接收的接收信号强度是否大于第一阈值。 此外,通过使用接收信号强度的转变模式的预测结果大于第一阈值来确定第一垂直切换。 当服务网络是第二网络时,确定从第二网络接收的接收信号强度是否小于第二阈值。 通过使用小于第二阈值的接收信号强度的转换模式的预测结果,决定第二垂直切换。 这里,第一阈值大于第二阈值。

    • A handover method and apparatus for a mobile terminal using location information in a network of heterogeneous systems are provided. The handover method uses service area map information provided by a location service server in a mobile communication network in which at least one or more heterogeneous wireless network systems are connected through a predetermined network and, includes: receiving service area map information transmitted from the location service server; the mobile terminal determining whether or not the location of the mobile terminal is within the service area map; and if it is determined that the mobile terminal is within the service area map, the wireless terminal selecting an accessible wireless network system and then activating a unit for communicating with a base station of the selected wireless network system. According to the method, a battery consumption problem that occurs by activating all modems when a wireless terminal, which is connected to a predetermined mobile communication system in an environment where a plurality of heterogeneous systems are overlapping each other, is searching for candidate systems in order to perform handover to a heterogeneous network, can be solved. Also, a problem where finding a candidate system is time-consuming can be solved.
    • 提供了一种在异构系统的网络中使用位置信息的移动终端的切换方法和装置。 切换方法使用由移动通信网络中的位置服务服务器提供的服务区域地图信息,其中至少一个或多个异构无线网络系统通过预定网络连接,并且包括:从位置服务发送的服务区域地图信息 服务器; 移动终端确定移动终端的位置是否在服务区域图内; 并且如果确定所述移动终端在所述服务区域映射内,则所述无线终端选择可访问无线网络系统,然后激活用于与所选择的无线网络系统的基站进行通信的单元。 根据该方法,当在多个异构系统彼此重叠的环境中连接到预定移动通信系统的无线终端时,通过激活所有调制解调器而发生的电池消耗问题正在按顺序搜索候选系统 可以解决异构网络的切换。 此外,可以解决发现候选系统耗时的问题。
