Signaling Conformance 3GPP TS 36.523-1 5G PCT

Protocol Conformance Testing (PCT) is the rigorous verification of the "language" spoken between a User Equipment (UE) and the network. Under the 3GPP TS 36.523-1 framework, we ensure that your device’s signaling stack—ranging from RRC to NAS layers—is flawless, secure, and globally interoperable.

• Interoperability Assurance: Guarantees seamless operation across diverse vendor eNodeB and gNodeB infrastructures.
• Legacy & Future Integration: Validates critical 5G Non-Standalone (NSA) anchors and 4G LTE fallbacks.
• Market Readiness: A mandatory prerequisite for GCF and PTCRB certifications.
• Reliability: Minimizes call drops, handover failures, and data throughput bottlenecks.

While 3GPP TS 36.523-1 serves as the primary technical prose, our testing methodology integrates the full compliance suite to ensure global acceptance:

• 3GPP TS 36.523-1: Test Case Descriptions and Procedures.
• 3GPP TS 36.523-2: Implementation Conformance Statement (ICS) and Applicability.
• 3GPP TS 36.523-3: Abstract Test Suite (TTCN-3) Specifications.
• Cross-Reference: Alignment with TS 38.523-1 for NR (New Radio) Standalone integration.

Our lab handles a diverse spectrum of chipsets and end-user hardware, including:

• Consumer Electronics: 5G Smartphones, Tablets, and Wearables.
• IoT & Telematics: NB-IoT/Cat-M1 modules and Automotive (C-V2X) units.
• Fixed Wireless: 5G CPEs, Routers, and Industrial Gateways.
• Infrastructure Components: Specialized 5G modems and chipset evaluation boards.

We dissect the signaling exchange to ensure every packet adheres to the 3GPP state machine:

• Emm & Gmm Management: Attachment, Detachment, and Tracking Area Updates (TAU).
• Session Management: Bearer establishment, QoS negotiation, and VoLTE/VoNR signaling.
• Mobility & Handover: Seamless transitions between 4G LTE and 5G NR (EN-DC).
• RRC Procedures: Connection setup, reconfiguration, and measurements in RRC_IDLE and RRC_CONNECTED states.

Quality is at our core. Our facility maintains:

• ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories.
• GCF/PTCRB Authorization: Recognized as an Authorized Test Lab (ATL) for wireless certification.
• Carrier Specific Approvals: Compliance with major global MNO (Mobile Network Operator) acceptance programs.

Protocol testing is a complex, iterative process. A standard test cycle typically spans:

• Pre-Conformance/Debugging: 1 – 2 Weeks.
• Formal Certification Execution: 2 – 4 Weeks (depending on the number of supported bands and features).
• Final Report Issuance: 3 – 5 Business Days post-testing.

To initiate testing, we require:

• Device Units: 3–5 Engineering/Final samples (unlocked for diagnostic access).
• Interface Requirements: Access to the USB/Diagnostic port for logging and AT Command control.
• Support Hardware: 2 sets of batteries, chargers, and any specialized RF cables/pigtails for conducted testing.

The cost of 5G PCT is highly variable based on your device's complexity. Factors influencing the quote include:

• Band Support: Number of LTE and 5G bands to be tested.
• Feature Set: Support for CA (Carrier Aggregation), MIMO, and specialized protocols like NB-IoT.
• Retesting Policy: Discounted rates for firmware revisions and bug fixes.
• Customized Quote: Please contact our technical sales team for a detailed BOM-based estimate.

For a smooth onboarding process, please prepare the following:

• PICS/PIXIT: Protocol Implementation Conformance Statement.
• User Manual & Technical Datasheet: Outlining RF capabilities and supported features.
• Firmware Version Declaration: A signed document stating the software version under test.
• Safety Data Sheets (SDS): For devices containing Lithium-ion batteries.
