    Abstract: A method for operating a cellular communications system of a type that includes a first type of terminal having real-time transmission needs and a second type of terminal having nonreal-time transmission needs. The method includes the steps of (a) determining at periodic intervals a total amount of capacity required to service the first type of terminals; (b) subtracting the determined amount from a current maximum capacity; and (c) allocating all or some of the remaining capacity, if any, to one or more of the second type of terminals.

    Abstract: A radiotelephone (10) capable of operation within a CDMA radiotelephone system. The radiotelephone includes a receiver (30) for receiving a paging channel transmission; a system time pseudonoise (PN) generator (18); and despreading circuitry (20, 22, 24 26, 28), having an input coupled to the receiver, for despreading the paging channel transmission received during at least a portion of the assigned slot. The assigned slot is predetermined to have a duration that is three times the duration of a rollover period of the system time pseudonoise (PN) generator (26.667 msec) and four times the duration of one frame (20 msec), or 80 msec. The use of predetermined masks for initializing the PN generators, and in particular a Long Code PN generator (32), is also described.
