Abstract
A method of facilitating multihoming in the case of a mobile node possessing an Upper Layer Identifier belonging to a home network, where the mobile node is assigned a Global Mobility Management anchor within the home network and a Local Mobility Management anchor within a visited network. The method comprises allocating to the mobile node a primary SHIM6 proxy at said Global Mobility Management anchor, and at least one secondary SHIM6 proxy at said Local Mobility Management anchor. At said primary SHIM6 proxy, a SHIM6 context is established on behalf of the mobile node in respect of a peer node; and the established context is shared with said secondary SHIM6 proxy. Locator switching is then performed in respect of traffic exchanged between the mobile node and said peer node at one of said primary and secondary SHIM6 proxies.
