摘要: The present invention discloses a method for applying multi-protocol label switching (MPLS) network in general packet radio service (GPRS). MPLS is established by multiple differentiated (DS) domains. Each DS domain constructed routers (LSRs) and edge (LERs). LER provides at least GPRS supporting node (SGSN) connected to wireless base station, gate (GGSN) network. At signalling plane, IP addresses of all SGSNs GGSNs are utilized establish one-to-one pre-created paths (LSPs) the backbone transmission LSP tunneling transmit packets between SGSN GGSN.
