Abstract
A switching device (PLMN-SW) in a mobile radio communication system (PLMN) which supports a GPRS-network allows to connect a terminal station (GPRS-MS) of the mobile radio communication network (PLMN) with one of a plurality of packet data communication networks (PDN PDN IN). The selection of the packet data communication network (PDN PDN IN) is based on the transmission of a specific network indication parameter (NIP) from the terminal station (GPRS-MS) of the mobile radio communication network (PLMN). The network indication parameter (NIP) is transmitted to a serving (GPRS) support node (SGSN) as a special parameter in a PDP context activation procedure. Thus, a large number of internet service providers (ISP ISP ISP ) can be connected to a GPRS-network.
