Abstract:
A method for providing adaptive gateway node selection in a general packet radio service (GPRS) network wherein said GPRS network includes a plurality of gateway GPRS support nodes (GGSN), each GGSN including Gn interface and a Gi interface for communicating with others communications nodes, comprising the steps of:monitoring a Gn interface or Gi interface associated with at least one GGSN of said plurality of GGSNs; detecting that said Gn interface or Gi interface associated with said at least one GGSN is non-connective; receiving a mapping request, the mapping request including at least one nomenclature; mapping the at least one nomenclature to one or more of said plurality of GGSNs using an entry of a data structure responsive to said step of receiving a mapping request; filtering at least one field of the entry of the data structure based, at least in part, on said step of detecting wherein said step of filtering further comprises the step of omitting a network address of said at least one GGSN with said non-connective interface from a response to the mapping request.
