PDP Context: Information sets held in MS and GSNs for a PDP address NSAPI: Network Service Access Point Identifier. An integer value in the range [0; 15], identifying a certain PDP Context.PDP Context Activation Procedure: PDP Context Activation Procedure + IP assignment + RoamingGPRS Transmission Plane: GPRS Transmission PlaneGTP: GPRS Tunnelling Protocol: GTP : GPRS Tunnelling Protocol (GSM 09.60 version 7.4.0 Release 1998) TID – Tunnel Identifier (IMSI + NSAPI) NSAPI: Network Service Access Point Identifier. An integer value in the range [0; 15], identifying a certain PDP Context. It identifies a PDP context belonging to a specific MM Context ID.Protocols at Gi interface: Protocols at Gi interfaceGPRS/Internet connection: GPRS/Internet connectionGPRS Charging: GPRS Charging “IRS Definition”: If you can’t charge for you services, it is a hobby, not a business!GPRS Charging: GPRS Charging 3GPP TS 32.015 V3.8.0 (2001-12) CGF: Charging Gateway Functionality SCF: Service Control FunctionWhere to find specifications?: Where to find specifications?
