Abstract: A controller in a network assigns a dedicated foreign radio talk group to each radio frequency (RF) site in the network for use by foreign radios during an incident event. The controller receives a registration request from a foreign radio and registers the foreign radio in a first RF site. The controller receives a talk group affiliation request from the foreign radio and, responsive to determining that the first RF site is in the incident event mode, affiliates the foreign radio with dedicated foreign radio talk group that is assigned to the first RF site, associated with at least one of a system identifier, a Wide Area Communication Network identifier and a talk group identifier provided by the foreign radio, and/or associated with the talk group identifier provided by the foreign radio and included in a master list including talk group IDs associated with a function.

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.
