Abstract:
1. A method, comprising: configuring one or more user stations and a switching and management infrastructure with a function that maps packet data protocol addresses of data transmissions to defined service access point identifiers; creating a packet data context for data transmissions of a packet data service by: associating a packet data protocol address with a service access point identifier used in an interface between the one or more user stations and the switching and management infrastructure; using the function to determine independently in the one or more user stations or the switching and management infrastructure the service access point identifiers for data transmissions of the packet data service; sending from a user station to an element of the switching and management infrastructure a packet data context activation request that comprises the independently determined service access point identifier; and sending from the element of the switching and management infrastructure to the user station a packet data context accept message, if the service access point identifier sent from the user station matches with a service access point identifier determined by the switching and management infrastructure.
