A method and a system for controlling a connection in a reiteration area of wibro cells

An access control method in a WiBro(Wireless Broadband Internet) cell overlapping area and a system therefor are provided to enable an ACR(Access Control Router) to send responses to all of serving RASs(Radio Access Stations) and peripheral RASs when responding to an initial ranging request, thereby increasing a call connection rate as reducing access delay time. A PSS(Portable Subscriber Station) transmits an initial ranging request message to a synchronized RAS(S310). The RAS transmits an Hbis initial ranging request message to an ACR(S320). The ACR transmits an Hbis initial ranging response message to the RAS which transmits the Hbis initial ranging request message and peripheral RASs included in a neighbor list of the RAS by responding to the request message(S330). The synchronized RAS transmits an initial ranging response message corresponding to the initial ranging request message to the PSS(S340).
