Abstract:
1. A computer-implemented method comprising: receiving, at a network node and from a client device via an access node with access restrictions, a request message over a communication network via tunneling, the request message associated with the client device requesting to obtain general access to the communication network via the network node, the receiving comprising receiving the request message prior to the client device receiving the general access to the communication network, the request message encoded to enable the client device to tunnel the request message through the access node to circumvent the access restrictions associated with the access node; enabling, using the network node, the client device to establish a data connection with the access node, the data connection with the access node configured to enable general access to the communication network; periodically receiving, at the network node and from the client device via the access node, a message at predetermined intervals over the communication network; and sending, to the client device and from the network node via the access node, responses to the periodic messages, wherein the responses to the periodic messages are configured to enable the client device to determine whether to terminate the data connection to the access node.
