Enhanced Techniques For Using Core Based Nodes For State Transfer

A communications method for use in a communications system including a first access node, said method comprising:

• receiving at the first access node, a signal from a mobile node, the signal being a signal used to initiate a transfer of state information;
• and
• communicating state information from the first access node to a second access node in response to the signal received by the first access node by transmitting the state information to a first network node coupled to the first access node and the second access node.

A computer program product stored on a computer-readable medium of a first access node and comprising code that when executed on at least one processor causes the at least one processor to:

• receive at the first access node, a signal from a mobile node, the signal being a signal used to initiate a transfer of state information;
• and
• communicate state information from the first access node to a second access node in response to the signal received by the first access node by transmitting the state information to a first network node coupled to the first access node and the second access node.

A first access node comprising:

• means for receiving at the first access node, a signal from a mobile node, the signal being a signal used to initiate a transfer of state information;
• and
• means for communicating state information from the first access node to a second access node in response to the signal received by the first access node by transmitting the state information to a first network node coupled to the first access node and the second access node.

A communications method comprising:

• receiving at a first access node, a signal from a mobile terminal, the signal being used to initiate a transfer of state information;
• and
• in response to receiving the signal from the mobile terminal, transmitting by the first access node, the state information to a second access node, the transmitting of the state information being used to initiate a transmitting of a routing update signal to a routing device.

A communications method comprising:

• receiving at a second access node, a signal from a first access node in response to an initiation of a transfer of state information at the first access node;
• and
• transmitting by the second access node, a routing update signal to a routing device after receipt of the state information.

A communications method comprising:

• receiving at a first access node, a signal from a mobile node, the signal being used to initiate a transfer of state information;
• and
• in response to receiving the signal from the mobile terminal, transmitting state information to a network node coupled to the first access node and a second access node, the state information to be sent from the network node to the second access node.
