Claim:
A mobile communication terminal which receives a program via a multicast sent from a wireless base station, comprising: a communication means for communicating with the wireless base station; an acquisition means for acquiring registration control information in order to prohibit registration to a program via a multicast sent from a wireless base station using the communication means; a registration control means for controlling the registration operation based on the registration control information; wherein the registration control means cancels the registration operation and prevents the mobile communication terminal from switching from an original frequency channel to a frequency channel on which the program is transmitted when the registration control information indicates that registration is prohibited for all mobile communication terminals and thereby prevents the mobile communication terminal from receiving the program; and wherein the registration control means cancels the registration operation and prevents the mobile communication terminal from switching from the frequency channel on which the program was transmitted back to the original frequency channel when the registration control information indicates that registration is prohibited for a portion of all mobile communication terminals.
