Abstract: A wireless device is determined to be in communication with a first access node is at a location in a coverage area of a first communication network, and it is determined whether the wireless device is in communication with the first access node using a first radio access technology or a second radio access technology. The availability of the first r and the second radio access technologies from the first communication network are determined, and the wireless device is permitted to register with the PTT communication system when the wireless device is in communication with the access node using the first radio access technology. Further, the wireless device is prevented from registering with the PTT communication system when the wireless device is in communication with the access node using the second radio access technology and the first radio access technology is available for the wireless device.
