Description

We'll need an implementation of the IuUP protocol described in 3GPP TS 25.415 and TS 25.414 for the RTP encapsulation.

Particularly the SMpSDU mode is important here.

The code should come as a library so it can be used by multiple different applications. It could implement the primitives described in Section 7 of TS 25.415 towards the user (RNL).

The laforge/iu_up branch of libosmocore contains some initial untested code for the CRC generation as well as for the primitives and a related FSM. This should be used as a base for the library code. This library code can then be used from osmo-mgw.

Implemented an encoder/decoder for IuUP accordint to TS 25.415 Chapter 6.6 in TTCN-3 for implementation of a test fixture. Next will be that test fixture with some inspection if wireshark decodes the payload correctly. After that, the fixture can be used towards testing the upcoming osmocom implementation.
