  • Patent number: 5121115
    Abstract: A paging network is disclosed which utilizes a plurality of distributed switches to transmit pages on a non-real time basis to achieve efficient and low cost transmission. Each of the switches processes packets of pages received from the network. Each of the switches also processes pages into packets of pages to be transmitted to another switch in the network or into batches of pages to be transmitted by a local paging service if the switch is a local switch. The network dynamically programs the reception channel(s) of the paging receivers in response to traffic conditions of a local switch or in accordance with service options specified by a subscriber to a local paging service. The digits of the paging receiver identification code are transmitted in an order of increasing significance to conserve battery life of the paging receivers. Pages may be initiated by placing a local call to any lata switch in the network and service options may be varied by placing of a local call to a lata switch.

  • Patent number: 5077834
    Abstract: A RF paging receiver which is tunable to channels to receive pages comprising characters to be displayed with the pages being transmitted in a plurality of licensed frequency bands with each band containing a plurality of FM channels in which signal strength of pages on received channels in the bands varies as a result of variable antenna gain with programming of channels being accomplished by channel programming commands in accordance with the invention includes a tunable antenna (12, 14) having a reception bandwidth spanning the frequency bands with the antenna being tunable in response to an antenna tuning signal to achieve maximum antenna gain for a received channel in any one of the plurality of licensed frequency bands; a RF tuner (16), coupled to the tunable antenna, for receiving individual channels from the bands in response to varying a receiver tuning signal specifying reception of one of the channels within the plurality of frequency bands, the RF tuner comprising a plurality of RF amplifiers (102

  • Patent number: 5052049
    Abstract: A paging receiver (10) is disclosed which is compatible with transmissions from analog or digital paging transmitters. The paging receiver has a command structure which permits it to be dynamically programmable to change its functionality including programming of the channel frequencies which the paging receiver is to receive. The programmability of the channel frequencies permits the paging receiver to be used for making national, regional, remote area, local area, and sublocal area pages, and pages to a group in the local area and to switch from channel frequencies which are heavily used during peak paging times to lesser used channels. The paging receiver transmits the paging receiver identification code digits in an order of increasing significance which significantly lessens power consumption for all paging receivers tuned to a particular frequency for determining if a page is to be received which prolongs paging receiver battery life.

  • Patent number: 5045850
    Abstract: A paging network which generates pages at a page source storing a plurality of subscriber files chosen from subscriber files stored at a plurality of switches located in the network. The destination to which a page is to be transmitted is determined by the network transmitting the page to the switch storing a number identical to the identification added to the page by the page source. A plurality of locations may be connected to the network with each location generating pages having a different type of information.
