Abstract

The invention relates to a method for managing communications of a physical network entity in an arrangement of physical network entities. The method comprises managing (101) communications of the physical network entity in the arrangement of physical network entities using a virtual management stratum, the virtual management stratum being associated with the physical network entity.

Claims

1-22. -22. (canceled)

23. A method for managing communications of a physical network entity in an arrangement of physical network entities, the method comprising:

managing communications of the physical network entity in the arrangement of physical network entities using a virtual management stratum, the virtual management stratum being associated with the physical network entity.

24. The method of claim 23, wherein managing communications further comprises exchanging a communication message between the virtual management stratum and another virtual management stratum which is associated with another physical network entity of the arrangement of physical network entities.

25. The method of claim 23, further comprising the virtual management stratum:

receiving a communication message;

performing one of determining a physical network entity of the arrangement of physical network entities to which the communication message pertains and randomly selecting a physical network entity from the arrangement of physical network entities to determine a physical network entity for forwarding the communication message; and

initiating a forward of the communication message towards the determined physical network entity.

26. The method of claim 23, further comprising the virtual management stratum:

receiving a communication message requesting a transmission of certain information towards a user entity;

determining a physical network entity in the arrangement of physical network entities which has the certain context; and

initiating a forward of the communication message towards the determined physical network entity to initiate a transmission of the certain information towards the user entity.

27. The method of claim 23, further comprising the virtual management stratum maintaining connectivity between the physical network entity and another physical network entity in the arrangement of physical network entities.

28. The method of claim 23, further comprising the virtual management stratum initiating a forward of a communication message towards another physical network entity in the arrangement of physical network to request a transmission of certain information towards the physical network entity.

29. The method of claim 23, further comprising the virtual management stratum:

initiating a forward of a communication message towards another physical network entity in the arrangement of physical network entities, the communication message comprising network information indicating at least one of a network load and an availability of the physical network entity.

30. The method of claim 23, further comprising the virtual management stratum:

determining a physical network entity in the arrangement of physical network entities towards which certain information is to be transmitted upon the basis of a complexity measure; and

initiating a forward of the certain information towards the determined physical entity.

31. The method of claim 23, wherein the arrangement of physical network entities comprises a network control node, a network management node and a user entity, the network control node communicating with the network management node, the network management node managing communications of the user entity, the virtual management stratum being associated with the network management node, the virtual management stratum managing communications of the network management node with the network control node or with the user entity.

32. The method of claim 23, wherein the arrangement of physical network entities comprises a network control node, a network management node and a user entity, the network control node communicating with the network management node, the network management node managing communications of the user entity, the virtual management stratum being associated with the network control node, the virtual management stratum:

maintaining a first communication link between the network control node and a first network management node of the arrangement of physical network entities; and

maintaining a second communication link between the network control node and a second network management node of the arrangement of physical network entities, the second communication link forming a stand-by communication link for the first communication link.

33. The method of claim 23, wherein the arrangement of physical network entities comprises a network control node, a network management node and a user entity, the network control node communicating with the network management node, the network management node managing communications of the user entity, the virtual management stratum being associated with the user entity, the virtual management stratum initiating a transmission of an attach request towards a virtual management stratum of the network control node to request an establishment of a communication link over a communication network.

34. The method of claim 33, further comprising the virtual management stratum locally generating a global unique temporary identity (GUTI).

35. A physical network entity for communicating in an arrangement of physical network entities, the physical network entity comprising:

a processor being configured to provide a virtual management stratum associated with the physical network entity, the virtual management stratum being configured to manage communications of the physical network entity in the arrangement of physical network entities.

36. The physical network entity of claim 35, the virtual management stratum further comprising a virtual entry point entity for communicating with another physical network entity of the arrangement of physical network entities.

37. The physical network entity of claim 35, the virtual management stratum further comprising a virtual mobility manager entity for identifying another physical network entity for performing one of holding certain information, and for transmitting certain information towards another physical network entity in the arrangement of physical entities.

38. The physical network entity of claim 35, the virtual management stratum further comprising a virtual topology manager entity for maintaining connectivity between the physical network entity and another physical network entity.

39. The physical network entity of claim 35, the virtual management stratum further comprising a virtual mobility optimization entity for determining another physical network entity in the arrangement of physical network entities towards which certain information is to be transmitted upon the basis of a complexity measure, and for initiating a transmission of the certain information towards the determined physical entity.

40. The physical network entity of claim 35, wherein the physical network entity is a network management entity managing communications of a user entity in the arrangement of physical network entities.

41. The physical network entity of claim 35, wherein the arrangement of physical network entities comprises a network control node, a network management node and a user entity, the network control node communicating with the network management node, the network management node managing communications of the user entity, the physical network entity being the network control entity, the virtual management stratum comprising a virtual mobility proxy entity for managing communications between the network control entity and the network management node.

42. The physical network entity of claim 35, wherein the arrangement of physical network entities comprises a network control node, a network management node and a user entity, the network control node communicating with the network management node, the network management node managing communications of the user entity, the physical network entity being the user entity, the virtual management stratum being configured to initiate a transmission of an attach request towards a virtual management stratum of the network control node, the attach request requesting an establishment of a communication link over a communication network.
