Communications system enabling radio link access for non-trunked radio units to a multifrequency trunked two-way communications systems
First Claim
1. An improved multifrequency trunked, two-way radio communication system selectively operating on an assigned one of a predetermined number of information channels and wherein in such system one or more non-trunked single fixed channel radio units may be provided access to the trunked system, comprising:
- a trunked controller;
a plurality of trunked remote stations having means to request a channel assignment from said trunked controller and means responsive to an assigned channel signal to operate on said channel;
said trunked controller having means to assign a channel to a requesting trunked remote station and means for truncating said remote station channel assignment;
a plurality of non-trunked remote stations operating on a separate single channel; and
a radio access link having means for receiving transmissions on said separate single channel from any of said non-trunked remote stations and means to request a channel assignment from said trunked controller in response thereto, and in response to a received assigned channel signal from said trunked controller to permit said plurality of non-trunked remote stations to operate on said assigned channel in the same manner as said plurality of trunked remote stations.

Abstract
An improved multifrequency trunked, two-way communications system is provided in which a plurality of conventional single channel radio units are provided access. The system includes a predetermined number of information channels that are shared by a plurality of trunked stations. A trunked controller assigns one of the information channels to a requesting trunked mobile unit. The requesting trunked mobile unit is enabled to operate on the assigned channel in response thereto.
The improved communications system includes a radio access link which enables the single channel radio units to operate on an assigned information channel in the same manner as the trunked remote stations. The radio access link provides the plurality of conventional remote stations automatic access to the trunked system without requiring any modification of the conventional remote stations, and likewise without modification of the trunked remote stations and trunked controller.

10. In a multifrequency trunked, two-way radio communications system having a trunked controller and a plurality of trunked remote stations selectively operating in an assigned one of plurality of information channels, a radio access link for providing one or more non-trunked remote stations operating on a separate, single fixed information channel access to the trunked system, said radio access link comprising:
-
means for receiving transmissions on the separate single channel from any of the one or more non-trunked remote stations and means to request a channel assignment from the trunked controller in response thereto, and in response to a received assigned channel signal from the trunked controller to permit the said one or more non-trunked remote stations to operate on said assigned channel in the same manner as the plurality of trunked remote stations. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of providing access for a plurality of non-trunked remote radio stations operating on a single fixed channel to a multifrequency trunked, two-way radio communications system having a trunked controller and a plurality of trunked remote stations operating on an assigned one of a plurality of information channels and permitting operation therewithin, comprising the steps of:
-
a. receiving a transmission from a non-trunked remote station; b. requesting a channel assignment from the trunked controller in response thereto; c. receiving a channel assignment from the trunked controller; and d. permitting said non-trunked remote station to operate on said assigned channel in the same manner as the trunked remote stations. - View Dependent Claims (18, 19, 20)
