1. A method for reporting location information at a terminal, the method comprising:
receiving a request for location information from a base station, wherein the request includes a reporting period, and wherein a length of the reporting period is determined by the base station based on a mode state of the terminal, wherein the length of the reporting period when the mode state is an idle mode is different from the length of the reporting period when the mode state is an active mode; reporting the location information to the base station according to the reporting period corresponding to the mode state of the terminal; and reporting the location information to the base station when an event is generated according to an event generating condition, wherein the length of the reporting period when the mode state is an idle mode is longer than the length of the reporting period when the mode state is an active mode; wherein receiving the request for location information comprises:
receiving a location based service (LBS) request message from the base station when the mode state of the terminal is the active mode; andreceiving a mobile paging advertisement message from the base station when the mode state of the terminal is the idle mode,wherein the LBS request message and the mobile paging advertisement message include the reporting period; and wherein the event is generated when a variation between current location information and finally reported information exceed a threshold.
