3GPP MCP Server

# V1 vs V2: Comprehensive Comparison ## Executive Summary The 3GPP MCP Server project offers two distinct approaches to AI-assisted 3GPP specification research: - **Version 1 (Data Hosting)**: Comprehensive specification storage and search - **Version 2 (Intelligent Guidance)**: Lightweight research guidance and methodology This document provides a detailed comparison to help users and organizations choose the right approach for their needs. ## Philosophical Differences ### **V1: "Library Approach"** *"Provide access to all the books"* - Store comprehensive specification content locally - Enable full-text search and content retrieval - Focus on immediate access to specification text - Emphasize completeness and self-sufficiency ### **V2: "Librarian Approach"** *"Teach how to find the right books"* - Provide intelligent guidance to external sources - Enable strategic research planning and methodology - Focus on education and skill development - Emphasize understanding and learning ## Technical Comparison ### **Resource Requirements** | Aspect | V1 (Data Hosting) | V2 (Guidance) | |--------|------------------|---------------| | **Storage** | 13.5GB+ (TSpec-LLM dataset) | <100MB (knowledge base) | | **Memory** | 2-4GB during operation | <100MB typical | | **Startup Time** | 2-5 minutes (large dataset) | <5 seconds | | **Network** | Internet for dataset download | None required | | **Maintenance** | Dataset updates, indexing | Knowledge base updates | ### **Performance Characteristics** | Metric | V1 (Data Hosting) | V2 (Guidance) | |--------|------------------|---------------| | **Response Time** | 3-5 seconds (search) | <500ms (guidance) | | **Concurrent Users** | ~50 (memory limited) | 1000+ (stateless) | | **Scalability** | Vertical (more RAM) | Horizontal (more instances) | | **Cold Start** | Slow (dataset loading) | Fast (minimal setup) | | **Resource Usage** | High, persistent | Low, on-demand | ### **Architecture Complexity** | Component | V1 Complexity | V2 Complexity | |-----------|---------------|---------------| | **Search Engine** | Complex (vector + text) | Simple (pattern matching) | | **Data Pipeline** | Heavy (document processing) | Lightweight (knowledge lookup) | | **Caching** | Multi-layer (L1-L3) | Minimal (templates only) | | **Dependencies** | Many (ChromaDB, embeddings) | Few (core libraries only) | | **Deployment** | Complex (database setup) | Simple (single binary) | ## Functional Comparison ### **Core Capabilities** #### **Search and Discovery** **V1 Approach**: ```typescript // Full-text search with semantic understanding const results = await server.callTool('search_3gpp_specs', { query: 'NAS authentication procedures', series: ['24'], limit: 10 }) // Returns: Actual specification content with relevance scores ``` **V2 Approach**: ```typescript // Intelligent research guidance const guidance = await server.callTool('guide_specification_search', { query: 'NAS authentication procedures', userLevel: 'intermediate' }) // Returns: Research strategy, suggested specs, methodology ``` #### **Information Depth** | Information Type | V1 (Data Hosting) | V2 (Guidance) | |------------------|------------------|---------------| | **Specification Text** | ✅ Full content | ❌ No content | | **Search Results** | ✅ Ranked matches | ❌ No search | | **Cross-References** | ✅ Document links | ✅ Relationship guidance | | **Contextual Help** | ⚠️ Basic context | ✅ Rich guidance | | **Learning Support** | ❌ Minimal | ✅ Comprehensive | | **Methodology** | ❌ None | ✅ Detailed strategies | #### **Response Examples** **V1 Response Style**: ``` Found 3 specifications matching "NAS authentication": **TS 24.301** - Non-Access-Stratum protocol for EPS (Relevance: 85%) Content: "4.2 Authentication procedures The authentication procedure is initiated by the network..."

[3000+ words of specification text] ``` **V2 Response Style**: ``` For NAS authentication procedures research, I recommend this strategic approach: **Primary Specifications to Study:** • TS 24.301 (4G NAS): Sections 4.2-4.4 for EPS authentication • TS 24.501 (5G NAS): Sections 4.2-4.4 for 5GS authentication • TS 33.501 (5G Security): Chapter 6 for authentication architecture **Research Strategy:** 1. Start with TS 33.501 Ch.6 for conceptual overview 2. Compare 4G (TS 24.301) vs 5G (TS 24.501) procedures 3. Focus on key differences: SUCI vs IMSI, 5G-AKA vs EPS-AKA **Key Search Terms for 3GPP.org:** - "SUCI encryption", "5G-AKA procedure", "authentication vector" - Filter by series 24 (protocols) and 33 (security) **Expected Learning Outcomes:** - Understand identity protection improvements in 5G - Know when to use different authentication methods - Grasp the security architecture evolution Would you like me to elaborate on any specific aspect or help you formulate more targeted research questions? ``` ## Use Case Suitability ### **V1: Data Hosting -
