Abstract  Abstract

A communications system in which information is transmitted in successive time slots grouped into a plurality of superframes which are in turn grouped into a plurality of hyperframes. A remote station is assigned to one of the time slots in each of the superframes for paging the remote station each hyperframe including at least two superframes and the information sent in the assigned time slot in one superframe in each hyperframe is repeated in the assigned time slot in the other superframe(s) in each hyperframe. Each superframe can include a plurality of time slots used for sending paging messages to remote stations grouped into a plurality of successive paging frames and the time slot to which the remote station is assigned is included once in every paging frame. Also each superframe may include time slots comprising a logical channel for broadcast control information and time slots comprising a logical paging channel. Information sent in the assigned time slot may direct the remote station to read the broadcast control information and the information may have been encoded according to an error correcting code and include a plurality of bits having polarities that are inverses of cyclic redundancy check bits produced by the encoding. Also the broadcast control information may comprise special messages that are included in respective time slots comprising a logical special message channel the time slots of the special message channel may be grouped in successive SMS frames and the SMS frames may be synchronized to start with a start of a superframe.
