TLDR
In this paper, the authentication of system status OSWs in a trunked communication system is provided by first verifying (411) that a received system ID (313) matches a pre-programmed system ID before the information in the status OSW is programmed into a communication unit.Abstract:
Authentication of system status OSWs in a trunked communication system is provided by first verifying (411) that a received system ID (313) matches a pre-programmed system ID A system status OSW must then be matched twice before the information in the system status OSW is programmed into a communication unit (115), thus limiting the possibility of false decoding of system status OSWsread more

Extended trunked RF communications systems networking
TL;DR: In this paper, a dedicated Network Interface Module (NIM) is provided in the multisite switch to facilitate interconnection and communication between multiple networks of similar multsite switch controlled architectures to create an "extended" mega-network.
Patent
Cellular fraud deterrent system
TL;DR: In this paper, a system for deterring fraudulent cloning by a reader station of valid call-origination message parameters assigned to authorized mobile radiotelephone stations operating within a cell or other area of a cellular radio system was proposed.
Patent
Efficient message switching in a switching apparatus
TL;DR: In this paper, a system and method of transferring packets/cells and messages within a switching apparatus that includes a plurality of input units (100, 192), a packet/cell switch element (160), a message controller (130), and an output unit (190, 194) is described.
Patent
System and method for preventing unauthorized use of a micro cellular system
TL;DR: In this paper, a micro cellular system (MCS) which co-exists with a cellular system in a frequency band is prevented by providing a control unit 2 in the MCS and a system ID receiving and judging unit which is capable of receiving all the downward control channels used in the CMTS.
Patent
Method for indicating a band plan for a trunked radio communications system
TL;DR: In this article, a trunked radio communications system receives an outbound signaling word comprising at least an opcode field, a site identification field and a four bit band plan field, where opcode fields indicate that the outbound message is a system status message and band plan fields indicate the band plan in use on the site.

Patent
Mobile radio transmission system
TL;DR: In this article, the authors propose a registration procedure to prevent frequent re-registrations when the mobile station repeatedly crosses the boundary between two service areas, and when it registers with a new base station and hence a new service area it retains its registration with at least one service area with which it is already registered.
Patent
Signalling method for establishing trunked communication
TL;DR: In this article, a trunked communication signalling protocol is provided by a unifying signalling protocol in which subscribers request communication channels using only their individual IDs encoded into a single ISW, and the central decodes the call request, extracts the requesting subscriber's individual ID, which is cross referenced to determine the subscriber's talk-group affiliation(s).
Patent
System for off-the-air reprogramming of communication receivers
Walter Lee Davis,Nasrin Sirang +1 more
TL;DR: In this paper, a programmable controller uses instructions in a non-volatile reprogrammable memory to decode and process the signals, and to output the information contained in the signals in a useable form.
Patent
Method and apparatus for coordinating independent communications systems
TL;DR: In this paper, a method and apparatus for coordinating the transfer of communications control from one independent radio communications system to another is disclosed, where a remote unit which communicates data messages is associated with a home system which has a plurality of fixed sites and overlapping radio coverage areas.
Patent
Dispatch trunked radio system.
TL;DR: In this article, a dispatch trunked radio system (100) which provides for individual subscriber to subscriber communication as well as other enhanced trunking features is presented. But the system is not compatible with prior ''single-word'' subscriber units.
