corescope's Introduction

srsRAN

srsRAN is an open source 4G software radio suite developed by SRS. For 5G RAN, see our new O-RAN CU/DU solution - srsRAN Project.

See the srsRAN 4G project pages for information, guides and project news.

The srsRAN suite includes:

srsUE - a full-stack SDR 4G UE application with prototype 5G features
srsENB - a full-stack SDR 4G eNodeB application
srsEPC - a light-weight 4G core network implementation with MME, HSS and S/P-GW

Decoding error on NAS: 5GS tracking area identity list with more than one element

Issue Description

Corescope fails parsing the "5GS tracking area identity list" form the NAS-PDU inside a Registration accept message when the list contains more than one TAC.

5GS tracking area identity list
    Element ID: 0x54
    Length: 43
    Partial tracking area list  1
        .00. .... = Type of list: list of TACs belonging to one PLMN or SNPN, with non-consecutive TAC values (0)

        Mobile Country Code (MCC): Unknown (1)
        Mobile Network Code (MNC): Unknown (01)
        TAC: 1
        TAC: 2
        TAC: 3

        TAC: 123
        TAC: 141
        TAC: 151
        TAC: 152

Setup Details

git rev a7fd328
Running corescope against an instance of Open5Gcore from Fraunhofer FOKUS.
The AMF has configured support for a total number of 13 TAC.

Sending of unexpected Configuration update complete NAS message.

Issue Description

corescope is sending an configuration update complete response when it is not requested to by the core.
According to 3GPP TS 24.501 Section 5.4.4.3.:

If "acknowledgement requested" is indicated in the Acknowledgement bit of the Configuration update indication IE in
the CONFIGURATION UPDATE COMMAND message, the UE shall send a CONFIGURATION UPDATE
COMPLETE message.

Setup Details

running corescope against an instance of of the open5gcore from Fraunhofer FOKUS.

Expected Behavior

No reply was expected to the configuration update command message.

Actual Behaviour

corescope replies with a configuration update complete message.

Steps to reproduce the problem

send a NAS PDU with the following contens to corescope:

NG Application Protocol (DownlinkNASTransport)
