METHODS AND ARRANGEMENTS FOR PREFIX MANAGEMENT IN MOVING NETWORKS

摘要

The present invention relates to prefix management in a moving network (101 ') comprising a first mobile router (104) which is assigned a first prefix for use when passing traffic to and from a home agent (112) with which the first mobile router (104) is associated, and a second mobile router (105). The present invention relates to methods and arrangements in the first mobile router (104), the second mobile router (105) and the home agent (112) for delegating the right to use said first prefix to said second mobile router (105) in a secure manner by means of first and second authentication information that may be compared to verify that the second mobile router (105) has the right to use the first prefix.
