Pau Espin 6e59534d6b Add initial SBc-AP support to osmo-cbc 
This patch makes use of the newly introduced sbcap library, and
introduces new code (and extends existing one) to handle all the aspects
of MME peers talking SBc-AP and its underlaying SCTP connection.

This commit doesn't aim to implement all the SBc-AP features, but to
implement a minimal subset of features already available for CBSP in
osmo-cbc, in order to have similar support level for both 2G and 4G
networks.

osmo-cbc - Osmocom Cell Broadcast Centre

This repository contains a C-language implementation of a minimal 3GPP Cell Broadcast Centre (CBC). It is part of the Osmocom Open Source Mobile Communications project.

A Cell Broadcast Centre is the central network element of a cellular network for distribution of Cell Broadcast and Emergency messages.

This code implements

  • the CBSP protocol on the CBC-BSC interface
  • a custom HTTP/REST based interface for external users to create/delete CBS messages

We plan to add support for the following features in the future:

  • the SABP protocol on the CBC-RNC (or CBC-HNBGW) interface for UMTS support
  • the SBcAP protocol on the CBC-MME interface for LTE support
