Hi,

 

As far as I know, there is no RAR message in Sh Interface.

Yes I know, there is no such message in Sh defined

The messages supported in Sh Interface are

UDR/UDA

PUR/PUA

SNR/SNA

PNR/PNA

 

All these messages use the application ID of Sh.

Someone just threw example of Sh scenario where server reqeust authentication - I didnt find anything about that in TS, rfc or google, neither I was able to find any example scenarios (of any kind, not regardign this particular case), so I have decided to post here.
Up until now I was sure that there is not authentication in Sh scenarios, or is there?
Is there any case of application that uses base messages? I mean there is no app id in Base, this would indicate that all aplication have to support those?

Can you please elaborate more on the context of RAR in the Sh interface?

Subject: [Dime] Application ID, Session Id and message flows

 

Hi

Im trying to figure few things out for some time now and up until now I have been hearing contradicting voices wherever I turn myself.
I would like to know what are values of ApplicationID set in messages - Base messages used in context of Sh interface to Authanticate/Authorize user?

Lets consider flow like follows (not sure if its valid or not):




CLIENT                        

       SERVER(HSS ?)
     | -------------    UDR -----------------> |                             SesssionId_1, AppId_1 ==Sh
                           X
     | <-----------    RAR ------------------- |                             SessionId_2, AppId_2= Base
     | -------------    RAA -----------------> |                             SessionId_2, AppId_2= Base
     | -------------    UDR -----------------> |                             SesssionId_1, AppId_1 ==Sh
     | <-----------   UDA -------------------- |                             SesssionId_1, AppId_1 ==Sh


Does X indicates UDA denying access?
Is SessionId_1 equal to SessionId_2?
Is AppId_2== Base or is it equal to AppId_2 ?


Thanks
