METHOD FOR MAKING WIRELESS LOCAL AREA NETWORK IN A WIRELESS METROPOLITAN AREA NETWORK AND THEREOF WIRELESS COMMUNICATION SYSTEM

摘要

According to the present invention, a mobile terminal performs a wireless area service during a first time period, thereby performing data transmission and reception with at least one mobile terminal connected to the wireless local area network, which is included in the wireless wide area network, and performs a wireless wide area service during the second time period. Transmitting data received from the at least one mobile terminal to a base station of the wireless wide area network by receiving a service, receiving data to be transmitted from the base station to the at least one mobile terminal, and real time among the at least one mobile terminal If there is a mobile terminal requesting a service, data transmission / reception for the real time service is periodically performed with the mobile terminal requesting the real time service and the base station, and a first polling period is determined in response to the mobile terminal requesting the real time service. , The other mobile terminal requesting the real-time service zone If not, a second polling period is determined, the information on the determined second polling period is transmitted to the base station, and the mobile station requesting the real-time service is periodically polled by the determined first polling period, thereby performing the real-time service. Perform data transmission / reception for the mobile station, and perform data transmission / reception for the real-time service according to polling periodically performed from the base station by the determined second polling period, wherein the first time period and the second time period are on a time axis. They have different positions from each other and alternately exist until the at least one mobile terminal completes data transmission to the base station.;Wireless communication system, wireless wide area network, wireless local area network, dual mode terminal, relay
