Paging system with separate transmission paths for control and data
First Claim
1. A paging system, comprising:
- a primary paging system for generating paging information and control information, said control information utilized in conjunction with said paging information;
a primary transmission link;
a secondary transmission link;
said paging system having;
a first paging system transmitter for transmitting at least said control information over said primary transmission link, anda second paging system transmitter for transmitting at least said paging information through said secondary transmission link;
a plurality of remote paging sites, each disposed at one of said remote paging sites such that both said primary transmission link and said secondary transmission link are connected thereto at the other end thereof, each of said paging sites having;
a primary paging receiver for receiving from said primary paging link the transmission from said first paging system transmitter including at least said control information,a secondary paging receiver for receiving from said second transmission link the transmission from said second paging transmitter including at least said paging information,a memory for storing the information received by said secondary paging receiver including at least said paging information, anda remote paging transmitter for transmitting at least said paging information stored in said memory to a plurality of portable receivers disposed proximate to said remote paging transmitter, said pagingtransmitter transmitting at least said paging information stored in saidmemory in response to information contained in said control informationreceived by said primary paging receiver.

Abstract
A paging system includes a paging terminal that is operable to receive paging signals and transmit them up to a satellite (28) and down through a downlink (312) to stick locations (314), (316), (318), (320) and (322). Each of the sticks (314)-(322) is associated with a given locale (324), (326), (328), (330) and (332). The sticks are operable in a simulcast mode and also in a cellular mode. In the cellular mode, each of the sticks (314)-(322) is operable to receive a separate message that is distinct from the other cells. Pagers (36), having a known location at any of the locales (324)-(332) can then be selectively addressed and data transferred thereto. To prevent interference between adjacent RF locales, adjacent cells are not turned on during transmission to select cells in the cellular mode. These can be turned on at a different time. Orthogonal coding can be utilized such that adjacent cells can be turned on, thus increasing throughput. The paging system operates by providing a primary transmission path and a secondary transmission path. The primary transmission path is operable to transmit only control information. The secondary transmission path is operable to transmit only data. The data is received by a secondary paging receiver and stored in the memory whereas the terminal information is received by a primary paging receiver. Upon receiving control information associated with the stored paging information, the paging information is then transmitted by the paging transmitter.
