Abstract:
1. A first mobile router, MR, connectable to a first moving network associated to a home agent, HA, the first moving network comprising at least a second MR, wherein each of the MRs is adapted to have a relation with said HA and to be assigned a first set of network prefixes identifying the first moving network, the first MR comprising: means for determining if the first moving network is split into a second and a third moving network such that the first MR belongs to the second moving network, means for transmitting a request to said HA to be re-assigned the first set of network prefixes if it is determined that the first moving network is split into a second and a third moving network, means for being re-assigned the first set of network prefixes if it is determined that the first moving network is split into a second and a third moving network and if local connectivity between the first MR and all other MRs that are assigned the first set of network prefixes is verified, means for switching to a second set of network prefixes if it is determined that the first moving network is split into a second and a third moving network and if local connectivity between the first MR and all other MRs that are assigned the first set of network prefixes is not verified; means for waiting a time period after determining that the first moving network has been split before transmitting a request to said HA to be re-assigned the first set of network prefixes; and means for selecting the length of said time period based on the number of nodes in the second moving network, such that a greater number of nodes results in a longer time period than a smaller number of nodes.
