Wireless frequency changes for wireless communication devices based on tracking area updates
View Patent ↗Systems, methods, and software for wireless frequency changes for wireless communication devices based on tracking area updates in wireless communication systems are provided herein. In one example, a method of operating a communication system is provided. The method includes providing wireless access to communication services for wireless communication devices over a first frequency spectrum at a wireless access node, and receiving tracking area updates transferred by ones of the wireless communication devices. The method also includes processing at least a quantity of the tracking area updates received at the wireless access node to determine idle timers for the wireless communication devices, where an expiration of an associated idle timer indicates that an associated wireless communication device can no longer receive the wireless access over the first frequency spectrum and can receive further wireless access over a second frequency spectrum.
