  3. Who we are/ what are we doingConsult / Design / Make & Ship process DNP IP addressing Communication matrix Customized output based on customer requirements Yes Tool support needed / available? Detailed planning Inputs from consultative phase IP Planning Tool SECANT No EPF Engineering Planning Folder Site Survey • Detailed planning phases includes: • Detailed IP planning • SECANT tool for IP planning - optional • A certified planner can produce the DNP based on HW configuration guidelines and IP planning guidelines • Outputs are • DNP & EPF • DNP used to fill the TPD (cooperation with Staging Center) • SECANT files (TPD export, ACL rules, communication matrix) TPD Technical Project Data Part of the output used for TPD TPD load specific Different types: HSS, CSCF, PCS

  4. What we need for IP planning • Reaching a common definition of External Interfaces ASI/PAE • VLANs definition with assigned IP addresses • Acceptance of hardware requirements • Deeper knowledge of the related equipments in the customer’s network • If possible , conducting the Site Survey • Agreement upon the way in which the solution will be implemented

  5. Planning aspects DNP – Documentation IT Net Planning Project specific … • System overview (overall & site specific) • System Configuration (detailed network diagramm) • Guaranteed connectivity to existing elements (“Interfaces”) • Network design • VLAN- and IP-Planning • IP Subnetting • Delivery of communication matrix for further security issues (e.g. Firewall Integration) • Component Adressing (IP-Adresses, Hostnamens, static routes, def GW, routing rules, etc.) • Easy usable specification for realization- and installation tasks Documentation Net Planning (DNP) Jhdslfueaöoföoifsödal Jhdlkjshdlkshfdkhjhfldjhf Kjsdöihkljhglfdskjhgalk kjhdsalfkjhadslkjfhdaslkjf 

  10. HSS IMS5.0 Core Network elements • CMS-8200: HSS – Home Subscriber Server • Stores the IMS User Profiles including the User Identification, Addressing information (Public-/Private User IDs, IMSI, MSISDN, ...), Service Provisioning Information (Filter Criteria), User Mobility Information (S-CSCF address), Charging Information (CCF-, ECF address), Radius Parameters (GCID, IP-address, SGSN-ID) • Provides support for User Authentication (AKA Authentication Vector) and Mobility Control. • The HSS therefore retrieves information from the HLR and the SMS-C via a MAP interface • Provides Subscriber Self Administration (SSA) support • CFX-5000: CSCF – Call Session Control Function • Can be viewed as a SIP based Multimedia Session Controller. • Includes the three 3GPP standard functions: S-CSCF, I-CSCF, P-CSCF. • The P-CSCF provides SigComp, QoS Support, Integrity/Confidentiality Support (IMS AKA) • The P-CSCF may also provide a SIP-ALG for NAT, Far-end NAT, IPv4/v6 translation and pinholing • The I-CSCF is the first contact point into the operator network and performs the S-CSCF Selection • The S-CSCF performs the User Authentication, Charging and Session/Service Control • The S-CSCF may also provide Mobility Control for Roaming and Handover • CFX-5000: BGCF – Breakout Gateway Control Function • Is responsible for selecting the MGCF that controls the IMS Interworking to the PSTN/CS-Domain. • The selection could e.g. be based on operator policy / Number Plan. • The BGCF is co-located with the S-CSCF. Each S-CSCF has a BGCF.
