Orthogonal frequency division multiplexing system access method and apparatus

The present invention provides an orthogonal frequency-division multiplexing access system, comprising the following processes: indicates whether the access terminal using the frequency resources reserved for access to the broadcast system message, which carries the reserved frequency resources access identifier, for way to access orthogonal frequency-division multiplexing system; in the case where the reserved frequency resources using the access terminal identifier indicates the access frequency resources reserved access mode, the access network to reserve at least one physical frame with successive transmission frequency resource access probe in an access terminal; the reserved frequency resources using the access terminal identifier indicates the case where the access frequency resources reserved access mode, access user terminal by transmitting on the reserved frequency resources probe access orthogonal frequency-division multiplexing system. Through the above technical solution, the present invention achieves the following advantageous effects: effectively solves the problem of a larger cell radius of the cell covered by the access counter, which effectively support the access system in a wide coverage.
