Patent ID: 7408943

Claim:
A method for exchanging information between components in a network which includes a core network and a radio access network, having terminal devices which exchange, via the network, IP information packets which have IP headers including IP addresses, having a memory area in which unique terminal device identifiers are administered in relation to IP addresses, comprising: routing, via at least one subset of MPLS-capable components in the network, the information packets through the network based on MPLS paths and corresponding MPLS headers; configuring the components such that the MPLS paths to the terminal devices are unique, the MPLS paths being identified by the unique terminal device identifier which is mapped in the MPLS headers; removing, via the MPLS capable components, at least part of the IP headers from the IP information packet to provide modified IP information packet with MPLS headers, the MPLS header including the terminal device identifier which is administered in relation to the IP address to send the modified data packet; and reading, via the MPLS-capable components, the MPLS headers of the information packets sent to determine an associated IP address based on the terminal device identifier to modify the information packet such that the original IP header replaces the MPLS header.
