This curriculum spans the technical workflows of a multi-phase network modernization program, covering the integration of mobile VoIP across RAN, core, and Wi-Fi domains with the depth required for operational deployment in regulated carrier environments.

Module 1: Radio Access Network (RAN) Design for VoIP Traffic

  • Selecting between LTE and 5G NR for VoIP based on latency targets and spectrum availability in dense urban deployments.
  • Configuring eNodeB or gNodeB parameters such as PRB (Physical Resource Block) allocation to prioritize VoIP over best-effort data.
  • Implementing semi-persistent scheduling (SPS) in LTE to reduce signaling overhead for periodic VoIP packet transmission.
  • Adjusting RLC and MAC layer timers to balance voice packet delay and retransmission efficiency.
  • Integrating QCI 1 (Quality of Service Class Identifier) into RAN policies to enforce strict jitter and packet loss thresholds.
  • Conducting drive testing with VoIP-specific KPIs (e.g., R-factor, MOS) to validate RAN coverage assumptions.

Module 2: Core Network Integration and IMS Architecture

  • Deploying dedicated P-CSCF instances in the IMS to handle SIP registration and session initiation for mobile VoIP.
  • Configuring S-GW and P-GW QoS policies to map EPS bearers to IMS voice flows with guaranteed bit rate (GBR).
  • Integrating ENUM and DNS SRV records to route SIP traffic across operator domains securely.
  • Implementing topology hiding and topology-agnostic routing in I-CSCF to protect internal network structure.
  • Setting up emergency call handling logic in the IMS to comply with regulatory location reporting (e.g., ETSI, FCC).
  • Managing interworking with legacy CS networks via MGCF and IM-MGW for fallback scenarios.

Module 3: Handover and Mobility Management

  • Configuring A3 and A5 event thresholds in LTE to trigger handovers without disrupting active VoIP sessions.
  • Implementing VoWiFi-to-LTE handover using ANDSF or ePDG policies based on signal strength and cost rules.
  • Enabling SRVCC (Single Radio Voice Call Continuity) to hand over VoLTE calls to 2G/3G CS domain at cell edge.
  • Calibrating T-REX and T-IMSI timers to balance mobility signaling load and session continuity.
  • Testing inter-RAT handover performance using real-time voice quality monitoring tools (e.g., PESQ, POLQA).
  • Managing bearer split scenarios in dual connectivity (EN-DC) to maintain VoIP QoS on primary carrier.

Module 4: Wi-Fi Integration and VoWiFi Deployment

  • Configuring WMM (Wi-Fi Multimedia) and WMM-AC to prioritize VoIP traffic over other Wi-Fi applications.
  • Implementing 802.11r fast roaming to reduce handoff latency between access points during VoIP calls.
  • Setting up secure tunneling via IPsec between UE and ePDG for encrypted VoWiFi session transport.
  • Integrating ANDSF policies to steer devices to Wi-Fi when cellular signal drops below -105 dBm.
  • Managing NAT traversal issues for SIP signaling using STUN/TURN servers in enterprise Wi-Fi environments.
  • Validating VoWiFi performance across heterogeneous AP vendors using standardized test profiles.

Module 5: Quality of Service and Traffic Prioritization

  • Mapping DSCP values from IP layer to 5G QoS Flow Identifiers (5QI) for end-to-end QoS enforcement.
  • Configuring uplink packet filtering in the UE to assign correct QCI to VoIP RTP and SIP packets.
  • Implementing weighted fair queuing in backhaul routers to prevent VoIP starvation during congestion.
  • Deploying deep packet inspection (DPI) to detect and classify non-compliant VoIP traffic from OTT apps.
  • Adjusting bufferbloat mitigation algorithms (e.g., FQ-CoDel) in CPE devices to reduce jitter.
  • Monitoring per-flow throughput and latency using PCAP-based probes at aggregation points.

Module 6: Network Coverage Optimization and Planning

  • Placing small cells in enterprise buildings to improve VoLTE uplink performance in low-SINR zones.
  • Optimizing antenna tilt and azimuth in macro cells to reduce interference on VoIP channels.
  • Conducting pilot testing with VoIP KPIs in fringe coverage areas to validate cell breathing effects.
  • Adjusting power control parameters (e.g., alpha, p0) to maintain uplink VoIP coverage at cell edge.
  • Integrating CDR analysis to identify coverage holes correlated with call drop events.

Module 7: Regulatory Compliance and Interoperability

  • Implementing lawful interception interfaces (e.g., LI-XML) for VoIP calls in compliance with CALEA.
  • Validating IMSI and TMSI handling in VoIP registration to meet GDPR and data minimization requirements.
  • Testing interoperability with third-party IMS providers using SIPconnect 2.0 profiles.
  • Ensuring emergency call routing supports PSAP location delivery via LIS and HELD protocols.
