Hello, everyone

I have a question on the procedure to register a GSCL to NSCL.

First, what I have understood about the implementation of OM2M :
1. GSCL send a RequestIndication to the NSCL and wait for ResponseConfirm primitive ;
2. If successful, NSCL creates local resources for GSCL and sends back a successful response to GSCL, GSCL registers to NSCL successfully ;
3. NSCL send a RequestIndication to the GSCL and wait for ResponseConfirm primitive ;
4. If successful, GSCL creates resources for NSCL and sends back a successful response to NSCL, NSCL registers to GSCL successfully.

Second, what I have understood about the standard ETSI M2M :
1. GSCL send a RequestIndication to the NSCL and wait for ResponseConfirm primitive ;
2. If successful, NSCL creates resources for GSCL and sends back a successful response to GSCL, GSCL registers to NSCL successfully ;
3. If GSCL receives a positive response, GSCL creates local resources for NSCL with NSCL id and other default attributes ;
4. GSCL sends a request to NSCL for its attributes and wait for response.
5. If NSCL sends back its information, GSCL updates the attributes locally.

The first two steps are the same, but the rest isn't. Anyone could explain this ?
Thanks.

Hi Hao,

What you said is correct, we implemented the registration mechanism using an other procedure. We will try to update the code, taking into account your remark, and push it in the OM2M GIT as soon as possible. An Email will be sent when this will be done.

Thanks.
Yassine Banouar.

Hi Yassine,
Thanks very much for your response.
Could you tell me when you could do this update?
Because I have to decide to wait for your update or do it in other way.

Hello Hao XU,

I pushed an update on the git repository including the correct GSCL/NSCL authentication procedure as described by ETSI.
In the updated version: after starting, the GSCL sends a request to register to the NSCL, if successful, the GSCL creates locally the required remote NSCL resource based on the config.ini file parameters.
The registration request initiated by the NSCL to GSCL is now removed, which simplify and optimize the registration procedure.
Thank you for this remark.
