METHOD AND PACKET DATA SERVING NODE FOR PROVIDING NETWORK ACCESS TO MOBILE TERMINALS USING PROTOCOL FOR CARRYING AUTHENTICATION FOR NETWORK ACCESS (PANA) AND POINT-TO-POINT PROTOCOL (PPP)

摘要

The invention relates to a method and a base station controller (BSC) for providing network access to mobile terminals (MTs) in a packet data network that uses Protocol for Carrying Authentication for Network Access (PANA) and Point-to-Point Protocol (PPP) simultaneously. The method performs at the BSC a selection algorithm at the BSC for selecting from a list of IP addresses of PANA/PPP capable packet data serving nodes (PDSNs) a PDSN for serving the MT. The PDSN further starts a PANA session or establishes a PPP session for the MT and this based on a MT PANA capability indicator previously received at the PDSN.
