Optimized information transfer associated with relocation of an IP session in a mobile communications system

A mobile communication system comprising a mobile node and one or more network nodes, wherein the mobile node is configured to:

• detect, from application context information on the mobile node, a first set of capabilities of a network node that facilitate maintaining an Internet Protocol (IP) session;
• query, from a potential next network node, capability information on the first set of capabilities;
• and
• determine applicability of the potential next network node to relocation of the IP session by the capability information on the first set of capabilities.

A mobile communication system comprising a mobile node and one or more network nodes, wherein

• the mobile node is configured to register a first set of capabilities in a first network node;
• wherein the first network node is configured to:
• query, from a potential next network node, capability information on the first set of capabilities;
• and
• determine applicability of the potential next network node to the relocation of an Internet Protocol (IP) session by the capability information on the first set of capabilities.

A mobile node in a mobile communication system, configured to:

• generate application context information based on at least one ongoing Internet Protocol (IP) session in the mobile communication system;
• detect from the application context information a first set of capabilities that facilitate maintaining the IP session;
• query, from a potential next network node, capability information on the first set of capabilities;
• and
• determine applicability of the potential next network node to relocation of the IP session by the capability information on the first set of capabilities.

A system for supporting relocation of an Internet Protocol session of a mobile node during a network layer handover in a mobile communication system, said system comprising:

• detecting means for detecting, from application context information on the mobile node, a first set of capabilities of a network node that facilitate maintaining the IP session;
• querying means for querying from a potential next network node capability information on the first set of capabilities;
• and
• determining means for determining applicability of the potential next network node to relocation of the IP session by the capability information on the first set of capabilities.
