Communication system and method
First Claim
1. A method of controlling a connection between a user terminal and an access node connected to a communication network, comprising:
- the user terminal establishing a data connection with the access node;
the user terminal periodically generating 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 responses to the periodic messages from the at least one network node;
analysing the responses to determine whether to terminate the connection to the access node; and
in the case that the connection to the access node should be terminated, transmitting a disconnect message to the access node from the user terminal.

Abstract
A method of controlling a connection between a user terminal and an access node connected to a communication network is provided. The user terminal establishes a data connection with the access node, periodically generates a message at predetermined intervals and transmits the periodic message to at least one network node via the access node over the communication network. Responses to the periodic messages are received from the at least one network node. The responses are analysed to determine whether to terminate the connection to the access node, and in the case that the connection to the access node should be terminated, a disconnect message is transmitted to the access node from the user terminal.

12. A communication system comprising:
-
a communication network; an access node connected to the communication network; at least one network node connected to the communication network; and a user terminal configured to establish a data connection with the access node, wherein the user terminal is arranged to periodically generate a message at predetermined intervals and transmit the periodic message to the at least one network node via the access node over the communication network, receive responses to the periodic messages from the at least one network node, analyse the responses to determine whether to terminate the connection to the access node, and, in the case that the connection to the access node should be terminated, transmit a disconnect message to the access node from the user terminal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
