S1AP protocol testing

[northmirko]

Hi, MTS-E//

Having problem with S1AP. Can you help ?
Trying to send PDU (S1SetupRequest):

<S1AP-PDU> <initiatingMessage> <procedureCode>17</procedureCode> <criticality>reject</criticality> <value> <S1SetupRequest> <protocolIEs> <protocolIEs> <id>59</id> <criticality>reject</criticality> <value> <Global-ENB-ID> <pLMNidentity>22F050</pLMNidentity> <eNB-ID> <macroENB-ID>11110011000001010000</macroENB-ID> </eNB-ID> </Global-ENB-ID> </value> </protocolIEs> <protocolIEs> <id>60</id> <criticality>ignore</criticality> <value> <ENBname>Mirko_Test_Sumarice</ENBname> </value> </protocolIEs> <protocolIEs> <id>64</id> <criticality>reject</criticality> <value> <SupportedTAs> <SupportedTAs-Item> <tAC>0100</tAC> <broadcastPLMNs> <PLMNidentity>22F050</PLMNidentity> </broadcastPLMNs> </SupportedTAs-Item> </SupportedTAs> </value> </protocolIEs> <protocolIEs> <id>137</id> <criticality>ignore</criticality> <value> <PagingDRX>v64</PagingDRX> </value> </protocolIEs> </protocolIEs> </S1SetupRequest> </value> </initiatingMessage> </S1AP-PDU>

but I am getting error:

`CAUSE: NotHandledCaseException

Great product, by the way.
I can't imagine every day working with Diametar without MTS.

Hi and thanks,

That one is tricky, this error happens in sub-project https://github.com/ericsson-mts/mts-asn1 (PER ASN1 decoder) because not all the spec was implemented.

In this case it looks like the case 16.6 from the PER encoding/decoding rules was not implemented.

You're welcome to take a look at it and do a pull request, but I'm afraid won't be having time to fix that in a reasonnably short term.
