Abstract: A digital voice storage system adapted for use in a multiple unit land mobile radio communications system. The system utilizes a PSK signalling system with fixed length data packets to control a system capable of multiple message storage of speech at mobile stations. Up to eight 64K dynamic RAMS are used in conjunction with a microprocessor to store up to 42 seconds of speech comprising up to eight separate messages. In addition, the system permits base interrogation of mobiles to determine if a message has been stored for review by the base operator and to determine the remaining recording capacity and total recording capacity of the mobile.

Abstract: In a wireless communications system (20), a beacon having a first radiation pattern (28) covering a portion of a subscriber service area (34) covered by a base station is transmitted. A subscriber (36) reception quality is then measured to produce a first beacon quality measurement (210). Thereafter, the first radiation pattern is changed to a second radiation pattern (32, 212), and a subscriber reception quality of the beacon transmitted with a second radiation pattern is measured to produce a second beacon quality measurement (214). In response to the first and second beacon quality measurements, a traffic channel radiation pattern (32) is selected (218), wherein such radiation pattern covers a portion of the subscriber service area. In a preferred embodiment, the beacon carrier frequency is the same as the traffic channel carrier frequency.

Abstract: A register-modelled radio system comprising a plurality of register-modelled processors having addressable registers for modelling the virtual state of the processor; a serial bus, interconnecting the register-modelled processors for communicating between the addressable registers; and a communications protocol for passing information to or from the addressable registers, whereby the virtual state of a radio portion may be determined or altered by, respectively, communicating information from or to the addressable registers. The communications protocol further comprises an information packet having an address, an operation code, optional data, and an error detection device, such as a cyclical redundancy check packet. The operation code is chosen from the group of primitive operation codes reset, read, write, bit set, bit clear, acknowledge, and negative acknowledge.

Abstract: A time division multiplexed (TDM) communication system, which apportions radio frequency communication channels into at least two time slots. Voice signals for transmission on this system are analyzed and vo-coded into a digital signal that is transmitted during one or more of the time slots. Received messages are recovered from at least one of these time slots and the voice message synthesized from the vo-coded signal. In this manner multiple voice messages may be transceived in a time division multiplexed manner on a single narrowband communication channel.
