Apparatus and method for processing connection failure in unlicensed mobile access (uma) network

A method for processing a connection failure in an Unlicensed Mobile Access (UMA) network, comprising:

• determining whether a message to determine a lower layer connection status is periodically received, while providing a current service;
• if the message to determine the lower layer connection status is periodically received, continuously providing the current service;
• and
• if the message to determine the lower layer connection status is not received periodically, transmitting a message to inform the connection failure of the lower layer.

A method for processing a connection failure in an Unlicensed Mobile Access (UMA) network, comprising:

• determining whether a node periodically receives from a other node a message to determine a lower layer connection status while providing a current service;
• if the node periodically receives the message to determine the lower layer connection status, continuously providing the current service;
• if the node does not receive periodically the message to determine the lower layer connection status, transmitting a message to inform the connection failure of the lower layer to the other node;
• if the other node receives the message to inform the connection failure of the lower layer, performing a connection failure management process;
• and
• if the other node does not receive the message to inform the connection failure of the lower layer, continuously providing the current service;
