Abstract:
1. A method of controlling a connection between a user terminal, configured to connect to a communication network, and an access node with access restrictions comprising: prior to receiving general access to the communications network via the access node, sending, using the user terminal, a message over the communication network to a network node using tunneling effective to facilitate obtaining a packet based communication service through the network node, the tunneling configured to circumvent the access restrictions associated with the access node; responsive to sending the message using tunneling, establishing, using the user terminal, a data connection with the access node, the data connection with the access node configured to enable general access to the communication network; periodically generating, using the user terminal, a message at predetermined intervals and transmitting the periodic message to at least one network node via the access node over the communication network; receiving, with the user terminal, responses to the periodic messages from the at least one network node; analyzing, using the user terminal, the responses to determine whether to terminate the connection to the access node; and responsive to determining that the connection to the access node should be terminated, transmitting, from the user terminal, a disconnect message to the access node, wherein analyzing the responses further comprises an ability to:
