SYSTEMS AND METHODS FOR USING INTERNET MOBILITY PROTOCOLS WITH NON INTERNET MOBILITY PROTOCOLS

摘要

A method for using Internet mobility protocols with non Internet mobility- protocols, e.g., in a 3GPP or an SEA/LTE system, is described. A first gateway node comprising a home Agent (304) as well as a Legacy Gateway Node (LGN 302)m which may be a Gateway GPRS Support Node (GGSN), communicates with a second gateway node comprising a Local Mobility Agent (LMA 314) as well as a Legacy Serving Node (LSN 312), which may be a Servicing GPRS Support Node (SGSN), using a first protocol. The first protocol is a non Internet mobility protocol, e.g., the GPRS tunneling protocol GTP. A home address (HoA) for a mobile node is managed by the second gateway node. Updates regarding the location of the mobile node within a domain are received using a second protocol. The second protocol is an Internet mobility protocol, e.g., Mobile IP (MIP). Intra-domain mobility for the mobile node is managed by the second gateway node using the second protocol. To manage the local mobility the Local Mobility Agent (LMA 314) uses a local mobility protocol, e.g., Hierarchical Mobile IP (HMIP), Fast Mobile IP (FMIP), Proxy Mobile IP (PMIP), or Network-based Local Mobility Management (NETLMM).
