Prefix delegation in a communication network
First Claim
1. A method of prefix delegation for a network entity in a communication network, the method comprising:
- at a network entity, receiving from a first neighbouring network entity a first prefix, said first prefix relating to said first neighbouring network entity, and a path length to a core network entity via said first neighbouring network entity;
at the network entity, receiving from a second neighbouring network entity a second prefix, said second prefix relating to said second neighbouring network entity, and a path length to a core network entity via said second neighbouring network entity;
selecting a neighbouring network entity on the basis of the path length to the core network entity; and
delegating a prefix for the network entity by concatenating the prefix of the selected neighbouring network entity with an identifier for the network entity.

Abstract
A method and apparatus for automated prefix delegation for a network entity in a communication network. A network entity receives from a first neighboring network entity a first prefix that relate to the first neighboring network entity, and a path length to a core network entity via the first neighboring network entity. The network entity also receives from a second neighboring network entity a second prefix that relates to the second neighboring network entity, and a path length to a core network entity via the second neighboring network entity. The network entity then selects a neighboring network entity on the basis of the path length to the core network entity, and delegates a prefix for the network entity by concatenating the prefix of the selected neighboring network entity with an identifier for the network entity.

11. A network entity for use in a communication network, the network entity comprising:
-
a receiver configured to receive from a first neighbouring network entity a first prefix, said first prefix relating to said first neighbouring network entity, and a path length to a core network entity via said first neighbouring network entity, the receiver further configured to receive from a second neighbouring network entity a second prefix, said second prefix relating to said second neighbouring network entity, and a path length to a core network entity via said second neighbouring network entity; a processor configured to select a neighbouring network entity on the basis of the path length and to delegate a prefix for the network entity by concatenating the prefix of the selected neighbouring network entity with an identifier for the network entity; and a first transmitter configured to send to a core network node the delegated prefix for the network entity. - View Dependent Claims (12)

13. A Rendezvous System node for use in a communication network, the Rendezvous System node comprising:
-
a first receiver configured to receive a registration message from a first network entity, the registration message including a delegated prefix for the first network entity, the delegated prefix comprising a concatenation of identifiers for network entities in a path between the first network entity and a core network entity and a prefix of the core network entity; a memory configured to store the delegated prefix for the network entity; a second receiver configured to receive, from a second requesting network entity, a request for the prefix of the network entity; a processor configured to determine from the memory the prefix of the first network entity; and a transmitter configured to send a message to the second requesting network entity, the message including the delegated prefix. - View Dependent Claims (14)
