Abstract
A method and system to avoid flooding a control channel after the end of a system-wide call is provided. A Land Mobile Radio (LMR) site tracks active channel assignments. The LMR site also receives a system-wide call request. Upon receiving the system-wide call request, a snapshot of the channel assignments is taken. When the LMR site receives an indication that the system wide call request has ended, the LMR site receives a de-assign complete message.
