Access node device for forwarding data packets
First Claim
1. An access node device arranged for receiving and forwarding data packets in a communication network, comprising at least one processor arranged to:
- receive data packets from a user node; and
forward the data packets in a stateless mode over a first path to a destination gateway node, the first path being a default path, orforward the data packets in a stateful mode over a second path to a destination node, the second path being determined by at least one of user or session specific information for said user node; and
receive instructions about policing, charging and security for data packets, from said destination gateway node when switching from forwarding the data packets in the stateless mode to forwarding the data packets in the stateful mode.

Abstract
Embodiments of present invention relate to an access node device arranged for receiving and forwarding data packets in a communication network, the device comprising at least one processor arranged to: receive data packets from an user node; and forward the data packets in a stateless mode over a first path to a destination gateway node, the first path being a default path, or forward the data packets in a stateful mode over a second path to a destination node, the second path being determined by user and/or session specific information for said user node. Furthermore, the invention also relates to a corresponding gateway node device, a method in an access node, a method in a gateway node, a computer program, and a computer program product thereof.

12. A method in an access node arranged for receiving and forwarding data packets in a communication network, the method comprising:
-
receiving data packets from a user node; and forwarding the data packets in a stateless mode over a first path to a destination gateway node, the first path being a default path, or forwarding the data packets in a stateful mode over a second path to a destination node, the second path being determined by at least one of user or session specific information for said user node; and receive instructions about policing, charging and security for data packets from said destination gateway node when switching from forwarding the data packets in the stateless mode to forwarding the data packets in the stateful mode. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A gateway node device of a communication network, comprising at least one processor arranged to:
-
receive data packets from a user node; identify said user node; transmit instructions to one or more access node devices whether data packets from said user node should be forwarded in a stateless mode over a first path to said gateway node device, the first path being a default path, or in a stateful mode over a second path to a destination node, the second path being determined by at least one of user or session specific information for said user node; and drop the data packets received from said user node if said user node is not authorized to transmit data packets to a service provider associated with said gateway node device. - View Dependent Claims (20, 21, 22)

23. A method in a gateway node of a communication network, the method comprising:
-
receiving data packets from a user node; identifying said user node; transmitting instructions to one or more access node devices whether data packets from said user node should be forwarded in a stateless mode over a first path to said gateway node device, the first path being a default path, or in a stateful mode over a second path to a destination node, the second path being determined by at least one of user or session specific information for said user node; and drop the data packets received from said user node if said user node is not authorized to transmit data packets to a service provider associated with said gateway node device. - View Dependent Claims (24, 25)
