What's New in NAS-1Step 5G r16.8.0 v8.3.4

Enhancements

The details of a UE policy management message delivered in a Registration request message's Payload container IE is made available by changing the representation of this IE from PayloadContainerContents (opaque ossOctetString) to UEPolicyManagementMessage.

Improvements

  • The sNSSAI and eapMessage fields of the NetworkSliceSpecificAuthentificationCommand, NetworkSliceSpecificAuthentificationComplete, and aNetworkSliceSpecificAuthentificationResult types are now mandatory as specified by the standard. Previously, to encode the corresponding messages correctly the user had to mark both fields in the bitmask as present; the decoder failed on valid messages.
  • A Routing Indicator field value with a length < 4 in a 5GS mobile identity information element for a "SUCI" type of identity and an "IMSI" SUPI format will now be encoded correctly. Previously, to correctly encode such a short value, it had to be padded with spaces to make it 4 in length.
  • Hexadecimal digits are now allowed in a UERadioCapabilityID information element. Previously, only decimal digits were allowed.
  • The UEPolicyManagementMessage type is simplified to avoid duplication of its length in encoded NAS messages.

What's New in NAS-1Step 5G r16.8.0 v8.3.2

Improvements

For some of the QoS rule operations, table 9.11.4.13.1 (Chapter 9.11.4.13) in TS 24.501 specifies the presence or absence of the QoS rule precedence and QoS flow identifier fields. For other operations, the standard does not explicitly specify whether these fields are absent or present.
In this version of OSS 5G NAS-1Step, the QoS rule precedence and QoS flow identifier fields are optional. Previously, unless the standard indicated otherwise, these fields were treated as mandatory.
NOTE: It is the responsibility of the application to make sure that when the optional segregationAndQFI field is present in a NAS message passed to ossNASEncode(), the antecedent optional qosRulePrecedence field is also present.
