The invention is a system and method of transmitting control information and user data, relating to multicast or broadcast services, between a first information entity (110) within at least one mobile station (104) and a second information entity (114) within a controller (106) of a wireless network (102) in which the at least one mobile station is located. The process of the invention includes originating control information from at least one first information entity; encoding the control information at the at least one mobile station on a logical channel; transmitting the logical channel on a physical channel from the at least one mobile station to the controller; decoding the physical and the logical channels at the controller and providing the control information to the second information entity; providing user data at the second information entity; encoding the user data at the controller on a logical channel; encoding the logical channel, on which the user data is encoded, on a physical channel and wirelessly transmitting the physical channel on which the logical channel is encoded from the controller to the at least one mobile station; and decoding the physical channel and the logical channel on which the user data is encoded at the at least one mobile station and providing the user data to at least one of the first information service entities.
