E2SM Ran Control Slice-level PRB Quota messages should skip the number 4

[gckopper]

Hello everyone!

In the issue #468 was discussed that the messages sent by the example xApp provided with flexric were not being decoded correctly by srsran, in part, because they didn't skip the number 4 when numbering the parameter ids, as per specification. Since then, the br-flexric branch of flexric has fixed the issue with this commit. However, srsran also changed its numbering so it doesn't skip the number 4. Now srsran's decoding is not in spec nor is the encoding in the xapp provided by the srsran/oran-sc-ric repo.

I'd like to know if this change was made intentionally in order to conform with the older version of flexric or if this is a bug?

Here is a screenshot from the spec (O-RAN.WG3.E2SM-RC-R003-v06.00) for quick reference.

Hi, thanks for pointing this out, we will match the order from the spec in the next release.

@gckopper,
Indeed we had set it intentionally to be interoperable with FlexRic, now that they have changed this we will do so too.

Hi @gckopper,

In preparation for our upcoming workshop in DC, we are contacting some users of our E2 solution. Can you please share a few lines about your experience with the E2 interface, what you were trying to achieve, and how it worked out for you?

Kind Regards,
Justin
