gsmap

gsmap is a Mobile Application Protocol (MAP) implementation written in Go. It provides a full protocol stack for mobile core network signaling, supporting the C, D, and E interfaces of MAP. This package is designed for use in telecom signaling, testing, and development environments.

Features

• MAP protocol implementation (C, D, E interfaces)
• TCAP, SUA, SCCP+M3UA, and SCTP protocol stacks
• SCTP support via Linux kernel module
• Modular and extensible Go codebase
• Suitable for building MAP-based applications, simulators, and test tools

Architecture

+-------------------+
|      MAP          |

|      TCAP         |

+-------------------+

• MAP: Implements Mobile Application Protocol logic for C, D, E interfaces.
• TCAP: Transaction Capabilities Application Part for dialog management.
• SUA/SCCP+M3UA: Signaling transport over IP networks.
• SCTP: Stream Control Transmission Protocol (Linux only).

Requirements

• Linux OS (SCTP support requires Linux kernel module)
• Not available on non-Linux platforms

Restriction

• Only UDT is supported (XUDT/LUDT is not supported) for SCCP
• Only connection less classes are supported for SCCP/SUA
• For SSNM xUA message, only recieveing is supported

Usage

You can use gsmap as a library in your Go project or as a base for building MAP-related tools and servers. Example (see roundrobin directory for a sample application):

import "github.com/fkgi/gsmap"
// Use gsmap APIs to build your MAP application
