Abstract: PURPOSE: A location information providing method in a wireless communication system is provided to effectively and rapidly supply location information if a terminal is an idle state. CONSTITUTION: A LBS(Location Based Service) control information includes a type of wireless location method which determines a terminal location. If a terminal is an idle state, a determining method of the terminal location is performed by using procedures of paging or raging.

Abstract: PURPOSE: A solution for the iterative problems of a data transmitting/receiving process in a mobile communication system is provided to improve the waste of resources by discarding a correctly received block through a reset process. CONSTITUTION: Transmitted-data is divided into blocks. Each generic number is given to the divided transmitted-data. A data block which is located in a pre-set window range is transmitted. The window range is a data block section which is transmitted through one data transmission. Normal receiving state is verified with respect to the transmitted data blocks. Normal receiving state is verified with respect to the non-transmitted data blocks. A discard message for requesting to discard the transmitted data block is transmitted. A window start advance field(610) is defined in addition to the discard message.
