## NAME

**osmo-sgsn** - Serving GPRS Support Node

## SYNOPSIS

## DESCRIPTION

**This is an implementation of the GPRS Serving GPRS Support Node (SGSN). As**  **such it implements the GPRS Mobility Management (GMM) and SM (Session** **Management).**

**Typically, you would start osmo-sgsn with the "-c" option specifying a** **configuration file. You can find example configuration files here:**

```
