Method and Apparatus for Route Optimization in a Telecommunication Network
First Claim
1. A method of controlling the routing of data packets sent from a first node towards a second node of a telecommunication network, the first node being a mobile node having an associated home network, and the method comprising:
- intercepting such a data packet;
determining if the packet relates to a first mode of communication between the first and second nodes in which data packets generally bypass a home agent associated with the first node'"'"'s home network, through which home agent packets would generally pass in a second mode of communication between the first and second nodes different to the first mode; and
dropping the packet if it is so determined and if dropping of the packet is determined to be in accordance with a predetermined routing policy.

Abstract
A method, access node, and mobile node for controlling the routing of a data packet sent from the mobile node towards a correspondent node of a foreign Internet Protocol (IP)-based telecommunication network different from a home network associated with the mobile node. The access router intercepts the data packet and determines whether the packet relates to a route optimization mode of the Mobile IP standard in which data packets bypass a home agent associated with the mobile node'"'"'s home network, or whether the packet relates to a bidirectional tunneling mode of the Mobile IP standard in which home agent packets pass through the home agent. The access router drops the packet when the packet relates to the route optimization mode and when dropping of the packet is determined to be in accordance with the predetermined routing policy.

25. An apparatus for controlling the routing of data packets sent from a first node towards a second node of a telecommunication network, the first node being a mobile node having an associated home network, and the apparatus comprising:
-
means for intercepting such a data packet; means for determining if the packet relates to a first mode of communication between the first and second nodes in which data packets generally bypass a home agent associated with the first node'"'"'s home network, through which home agent packets would generally pass in a second mode of communication between the first and second nodes different to the first mode; and means for dropping the packet if it is so determined and if dropping of the packet is determined to be in accordance with a predetermined routing policy. - View Dependent Claims (34)

26. A method of controlling the sending of data packets from a first node towards a second node of a telecommunication network, the first node being a mobile node having an associated home network, and the method comprising:
- not sending such a packet if it would relate to a first mode of communication between the first and second nodes in which data packets generally bypass a home agent associated with the first node'"'"'s home network, through which home agent packets would generally pass in a second mode of communication between the first and second nodes different to the first mode, unless the sending of such a packet is determined to be in accordance with a predetermined routing policy.

32. An apparatus for controlling the sending of data packets from a first node towards a second node of a telecommunication network, the first node being a mobile node having an associated home network, and the apparatus comprising:
- means for preventing the sending of such a packet if it would relate to a first mode of communication between the first and second nodes in which data packets generally bypass a home agent associated with the first node'"'"'s home network, through which home agent packets would generally pass in a second mode of communication between the first and second nodes different to the first mode, unless the sending of such a packet is determined to be in accordance with a predetermined routing policy.
