Stask@narus.com CoolTech Club Founding Meeting July 9, 2003Goals & Agenda : Goals & Agenda Acronyms flood - 2G, 3G, GSM, GPRS Challenges of the Mobile IP GPRS basic architecture GPRS components GGSN SGSN GTP – GPRS Tunneling Protocol Charging for GPRS services Q&AEvolution 2G , 2.5G and 3G : Evolution 2G , 2 .5 G and 3GGSM/GPRS acronyms : GSM/GPRS acronyms GSM - Global System for Mobile communication GPRS – General Packet Radio Service IMSI - International Mobile Subscriber Identity SIM – Subscriber Identity Module IMEI – International Mobile station Equipment Identity IP – Internet protocol ( often – address)GSM System Architecture: GSM System ArchitectureMobile IP challenge: Mobile IP challengeGPRS System Architecture: GPRS System Architecture PDN - Public Data NetworkGPRS Acronyms: GPRS Acronyms SGSN – Serving GPRS Supporting Node GGSN – Gateway GPRS Supporting Node CGF – Charging Gateway Functionality HLR – Home Location Register PDN – Packet Data Network PLMN – Public Land Mobile NetworkGPRS Logical Architecture: GPRS Logical Architecture (GSM 09.60 version 7.4.0 Release 1998)GPRS Routing Example Two IPs assigned: GPRS Routing Example Two IPs assignedPDP Context: PDP Context PDP: Packet Data Protocol (PDP) is a network protocol used by an external packet data network interfacing to GPRS. 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? ETSI - European Telecommunications Standards Institute www.etsi.org - official specifications 3GPP - 3 rd Generation Partnership Project www.3gpp.org - free specifications (work in progress) http://www.comsoc.org/livepubs/surveys/public/3q99issue/bettstetter.html - very good IEEE article , excellent starting pointPowerPoint Presentation: Q & A You do not have the permission to view this presentation.
