A robust, lightweight implementation of the MAP (Mobile Application Part) protocol in Go.

Overview

The go-gsmmap package provides simple and painless handling of MAP in the mobile networks, implemented in the Go Programming Language. It's designed to be straightforward to integrate into existing Go applications that need to interact with mobile networks.

The GSM-MAP structures in this library are directly defined as go structs with ASN.1 tags, making them lightweight and efficient.

Installation

go get github.com/gomaja/go-gsmmap
