Abstract: A method of managing a plurality of radio links in a WLL (Wireless Local Loop) is provided. The state of each radio link are defined as L2_NewLid indicating establishment of the radio link is requested but not completed, LNK indicating that a new connection is established to the radio link, and L3_AddReq indicating establishment of the radio link is pending. A data link layer of a base station manages each radio link between a terminal and the base station referring to the state of the radio link. Upon request for establishing a radio link, the data link layer sets the LNK of the radio link to 1. Upon request for releasing the radio link, the data link layer sets the LNK of the radio link to 0. Upon request for adding a radio link, the data link layer adds the radio link by checking the L2_NewLid and the LNK of the radio link.
