METHOD FOR ARBITRATING MULTI-HDLC NODE IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A method for arbitrating a multi-HDLC(High-level Data Link Control) node in a mobile communication system is provided to perform a plurality of routings to a bandwidth wanted to an H.110 bus of 8-MHz by constituting a logic for performing a routing of a multi-HDLC node in the H.110 bus and minimize an H.110 bus using the H.110 bus. CONSTITUTION: It is checked whether a bus usage requesting signal(OK) is generated from each node in a master mediation unit(ST11). In the case that a bus usage requesting signal is expressed in a specific HDLC node as a checking result, an RTS(Request To Send) of the expressed HDLC node is checked(ST13). If the RTS performs a low-to-high transition(ST14), CTS(Clear To Send) performs a low-to-high transition and a bus usage right is allocated(ST15). The RTS of the expressed HDLC node is continuously checked(ST16). If the RTS is canceled(ST17), a bus usage requesting signal of the next HDLC node is checked(ST18).
