ADDRESS REGISTRATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an address registration method that prevents data in a base station unit from being discarded by reducing a time required until reception start or reception restart of a mobile station unit. SOLUTION: A base station unit A connected to an Ethernet E provide a frame transmission service between a mobile station unit C via the unit A and the Ethernet E, manages a MAC address of the mobile station unit C in existence within a service area of the base station unit A, and discards a frame addressed to a mobile station unit to which no MAC address is registered. The mobile station unit C informs the base station unit A about the MAC address of the base station A before communication start.
