Abstract

Referring to Figure 1, a console (dispatcher point) interfaces a base station with a point-to-point link. Only the console that interfaces with a specific base station 'knows' that base station, i.e. the console can only communicate with that base station because it is aware of the base station type, the type of point- to-point link used, the protocol, the type of radio signalling used by the base station, the encryption type and the encryption key. A console that inter- faces a specific base station decrypts and encrypts messages from and to its base station, and translates voice and data to a common protocol which is dis- tributed to all consoles that share a dedicated local area network (LAN).

MULTI-BASE MULTI-DISPATCH COMMUNICATIONS SYSTEM WITH VOICE ON A LAN

by Oz Goren and Menachem Dismantstein

  Referring to Figure 1, a console (dispatcher point) interfaces a base station with a point-to-point link. Only the console that interfaces with a specific base station 'knows' that base station, i.e. the console can only communicate with that base station because it is aware of the base station type, the type of point- to-point link used, the protocol, the type of radio signalling used by the base station, the encryption type and the encryption key. A console that inter- faces a specific base station decrypts and encrypts messages from and to its base station, and translates voice and data to a common protocol which is dis- tributed to all consoles that share a dedicated local area network (LAN).

Each console can be divided into 3 sections (Figure
2):

i) an operator console with a mic, speaker, key- board and display;
ii) a base module with base interface circuitry, link, voice compression and encryption algorithem; and
iii) LAN interface module.

  Voice and control data from an operator will be transferred to the LAN to be routed a specific con- sole that uniquely interfaces with a desired base sta- tion. This specific console will translate the voice and control data to an appropriate language under- stood by the desired base station to which it is

interfaced. Communication between consoles is through the LAN without the need to involve base stations. A patch between two base stations may be created by control of one console designated as a supervisory console. Th...
