Welcome to CSN.1 and ASN.1 Message Analyser for 2G/GSM, 3G/UMTS, 4G/LTE standards. This WEB page provides online functionality to decode and encode the protocol stack messages between mobile station and network defined by 3GPP standard.
The decoder is a WEB based application for decoding and encoding protocol stack (2G / 3G / LTE) messages defined by 3GPP standard and encoded using ASN.1 algorithm.
Supported protocol stack layers:- GSM (2G) : RLC - Radio Link Control, MAC, RRC - Radio Resource Control
- UMTS (3G) : RRC - Radio Resource Control
- LTE (3.5G/4G) : RRC - Radio Resource Control
Features
- Showing Hex and Binary representation of the message elements.
For comfort of developers the decoder shows all parts of the message in Hex and Binary forms. - Better than Wireshark because
Not only decoding of message PDU is possible, but also composing & editing. You can choose version of 3GPP to be used for decoding.
Product Benefits
- saves your time;
- reduces errors in manual decoding;
- easy to use;
- up to date with the latest 3GPP specifications.

Decoding as Service:
M2M Web Service for automated decoding
A new Web Service is availabe now for automated decoding of the 3GPP air interface messages. It supports the CSN.1 and ASN.1 messages from 2G/GSM, 3G/UMTS, 4G/LTE defined by 3GPP standard (see full list of supported messages).
