Abstract
A method of operating a communication system comprises exchanging initial communications between a wireless communication device and a communication network over a wireless connection between the wireless communication device and a network access system and over a network connection between the wireless device and the communication network. The method further comprises, in response to a loss of the network connection due to a deterioration of the wireless connection, determining if a partial network entry process is possible to regain the connection, and if the partial network entry process is possible to regain the network connection, performing the partial network entry process. The method further comprises, in response to an improvement of the wireless connection and upon regaining the network connection, exchanging new communications between the wireless communication device and the communication network over the wireless connection and the network connection.
