Dynamic creation of channels in a simulcast wireless communication system
First Claim
1. In a communication system comprising at least a first and second simulcast station at a first remote site, a method comprising:
- detecting, by a simulcast site controller, unavailability of the first simulcast station for communicating on a first communication resource;
determining, by a simulcast site controller, if the second simulcast station is available for supporting simulcast transmissions on the first communication resource; and
if the second simulcast station is available, assigning, by a simulcast she controller, the second simulcast station to communicate on the first communication resource, sending, by a comparator, data to be communicated over the simulcast channel to one or more of the simulcast stations along with a timestamp specifying when the data will be transmitted, and communicating, by the second simulcast station, simulcast messages on the first communication resource, andwherein the communication system further comprises a plurality of simulcast stations distributed among a plurality of remote sites and where a subset of the plurality of simulcast stations communicates on the first communication resource and wherein the controller, comparator and simulcast stations are connected by an Internet Protocol network and the simulcast stations that communicate on the first communication resource share a multicast Internet Protocol address.

Abstract
Dynamic allocation of communication resources in a wireless communication system employing simulcast transmission. When a simulcast station of a simulcast channel at a remote site becomes unavailable, a simulcast site controller determines if there is an unused simulcast station at the remote site. If there is an unused simulcast station, the simulcast site controller assigns the unused simulcast station to the simulcast channel thereby allowing the simulcast channel to continue to function. In an alternate embodiment, simulcast stations at a plurality of remote sites are dynamically assigned to simulcast channels as they become available.

14. In a communication system comprising at least a first and second simulcast station at a first remote site, a method comprising:
-
detecting, by a simulcast site controller unavailability of the first simulcast station for communicating on a first communication resource by the first simulcast station notifying the comparator of a malfunction and the comparator notifying the simulcast site controller of the malfunction; determining, by a simulcast site controller, if the second simulcast station is available for supporting simulcast transmissions on the first communication resource; and if the second simulcast station is available, assigning, by a simulcast site controller, the second simulcast station to communicate on the first communication resource, sending, by a comparator, data to be communicated over the simulcast channel to one or more of the simulcast stations along with a timestamp specifying when the data will be transmitted, and communicating, by the second simulcast station, simulcast messages on the first communication resource. - View Dependent Claims (15, 16)

17. In a communication system comprising at least a first and second simulcast station at a first remote site, a method comprising:
-
detecting, by a simulcast site controller, unavailability at the first simulcast station for communicating on a first communication resource, wherein the unavailability of the first simulcast station is due to a problem with a connection between the first simulcast station and a comparator; determining, by a simulcast site controller, if the second simulcast station is available for supporting simulcast transmissions on the first communication resource; and if the second simulcast station is available, assigning, by a simulcast site controller, the second simulcast station to communicate on the first communication resource, sending, by a comparator, data to be communicated over the simulcast channel to one or more of the simulcast stations along with a timestamp specifying when the data will be transmitted, and communicating, by the second simulcast station, simulcast messages on the first communication resource. - View Dependent Claims (18, 19)
