    摘要: In order to reduce the size of a signalling message advertising prefixes, a super block prefix is determined amongst two or more prefixes having a common pattern. Information on the super block prefix and delta information on each non-super-block prefix is used in the messages instead of the prefixes as such, the delta information indicating how the prefix differs from the super block prefix.

    摘要: A telecommunication system comprising: a home agent, a first mobile router administrating a first IP address space and at least a second mobile router administrating a second IP address space; wherein network connections between said home agent and the first and the second mobile router are established via an IPv4-based network; said first and second mobile router being arranged to register their care-of addresses with the home agent. The home agent is arranged to send, upon noticing at least two mobile routers registered with the home agent, at least routing information of the first mobile router to at least the second mobile router, and the second mobile router is arranged to send, upon detecting data transmission destined to the first IP address space administrated by the first mobile router, said data transmission directly to the first mobile router for further forwarding to an IP address of an appropriate node.
