摘要：
There is provided a method for locating a terminal device in a network system, at least one network having several cells that are combined to form one or more tracking areas. The one or more tracking areas are combined to form an equivalent area. An exemplary method comprises transmitting a locating message from the terminal device to a network when the terminal device enters an equivalent area. Locating messages are also transmitted from the terminal device to the network at predetermined time intervals. The method also comprises indicating via the locating messages a sub-area of an equivalent area in which the terminal device is located during the transmission of a locating message. The method additionally comprises storing at least the sub-area indicated in a most recently received locating message by the network. The method further comprises transmitting at least a first terminal device tracking call by the network within the stored sub-area in order to locate the terminal device.
摘要（中）：
提供了一种用于在网络系统中定位终端设备的方法，至少一个网络具有被组合以形成一个或多个跟踪区域的几个小区。 一个或多个跟踪区域被组合以形成等效区域。 一种示例性方法包括当终端设备进入等效区域时，将定位消息从终端设备发送到网络。 定位消息也以预定的时间间隔从终端设备发送到网络。 该方法还包括在定位消息的发送期间经由定位消息指示终端设备所在的等效区域的子区域。 该方法还包括至少存储由网络在最近接收的定位消息中指示的子区域。 该方法还包括至少在存储的子区域内发送由网络跟踪呼叫的第一终端设备，以便定位终端设备。
