Ask about information elements (IEs), mobility, registration, requirements, and more; answers are grounded in the actual specs. **Built with [Agent Composer](/quickstarts/agent-composer)**, Contextual AI's framework for production-ready AI agents. ## The Knowledge Base The agent is connected to a datastore of 3GPP standards (e.g. Series 36 LTE, 38 NR, and others). The documents were obtained from the 3GPP archive using the [download\_3gpp](https://pypi.org/project/download_3gpp/) CLI and ingested for search and retrieval. ## What the Agent Does You can ask natural-language questions such as: * **IEs and parameters**: "What is the purpose of IE X in the RRC connection setup?" * **Mobility**: "What are the handover requirements for NR in Release 19?" * **Registration**: "Describe the registration procedure for 5G NR." * **Requirements**: "What does the spec say about timing for TAU?" The agent retrieves relevant chunks from the specs and synthesizes answers with citations to the source documents. ## Try the Demo Search the 3GPP spec yourself ## Learn More * [Contextual AI Demos](/examples/overview-demos) — All live demos in one place * [Agent Composer Documentation](/quickstarts/agent-composer) * [Prompt Builder Quickstart](/quickstarts/prompt-builder) * [Agent Composer YAML Guide](/how-to-guides/agent-composer-yaml)
