7.3.7 ULR-Flags
The ULR-Flags AVP is of type Unsigned32 and it shall contain a bit mask. The meaning of the bits shall be as defined in
table 7.3.7/1:
Bit Name
Description
0 Single-Registration-Indication
This bit, when set, indicates that the HSS shall send Cancel Location to the SGSN. An SGSN shall not set this bit when sending ULR.
1 S6a/S6d-Indicator
This bit, when set, indicates that the ULR message is sent on the S6a interface, i.e. the source node is an MME (or a combined MME/SGSN to which the UE is attached via E-UTRAN).
This bit, when cleared, indicates that the ULR message is sent on the S6d interface, i.e. the source node is an SGSN (or a combined MME/SGSN to which the UE is attached via UTRAN or GERAN).
2 Skip Subscriber Data
This bit, when set, indicates that the HSS may skip subscription data in ULA. If the subscription data has changed in the HSS after the last successful update of the MME/SGSN, the HSS shall ignore this bit and send the updated subscription data. If the HSS effectively skips the sending of subscription data, the GPRS-Subscription-Data-Indicator flag can be ignored.
3 GPRS-Subscription-Data-Indicator
This bit, when set, indicates that the HSS shall include in the ULA command the GPRS subscription data, if available in the HSS; it shall be included in the GPRS-Subscription-Data AVP inside the Subscription-Data AVP (see 7.3.2).
Otherwise, the HSS shall not include the GPRS-Subscription-Data AVP in the response, unless the Update Location Request is received over the S6d interface and there is no APN configuration profile stored for the subscriber, or when the subscription data is returned by a Pre-Rel-8 HSS (via an IWF).
A standalone MME shall not set this bit when sending a ULR.
4 Node-Type-Indicator
This bit, when set, indicates that the requesting node is a combined MME/SGSN.
This bit, when cleared, indicates that the requesting node is a single MME or SGSN; in this case, if the S6a/S6d-Indicator is set, the HSS may skip the check of those supported features only applicable to the SGSN, and if, in addition the MME does not request to be registered for SMS, the HSS may consequently skip the download of the SMS related subscription data to a standalone MME. NOTE2
5 Initial-Attach-Indicator
This bit, when set, indicates that the HSS shall send Cancel Location to the MME or SGSN if there is the MME or SGSN registration.
6 PS-LCS-Not-Supported-By-UE
This bit, when set, indicates to the HSS that the UE does not support neither UE Based nor UE Assisted positioning methods for Packet Switched Location Services. The MME shall set this bit on the basis of the UE capability information. The SGSN shall set this bit on the basis of the UE capability information and the access technology supported by the SGSN.
7 SMS-Only-Indication
This bit, when set, indicates that the UE indicated "SMS only" when requesting a combined IMSI attach or combined RA/LU.
8 Dual-Registration-5G-Indicator
This bit, when set by an MME over S6a interface, indicates that the HSS+UDM shall not send Nudm_UECM_DeregistrationNotification to the registered AMF (if any); when not set by an MME over S6a interface, it indicates that the HSS+UDM shall send Nudm_UECM_DeregistrationNotification to the registered AMF (if any). See 3GPP TS 29.503 [66].
An SGSN shall not set this bit when sending ULR over S6d interface.
9 Inter-PLMN-inter-MME handover
This bit, when set by an MME over S6a interface, indicates that an inter PLMN inter MME (or AMF to MME) handover is ongoing.
10 Intra-PLMN-inter-MME handover
This bit, when set by an MME over S6a interface, indicates that an intra PLMN inter MME (or AMF to MME) handover is ongoing.
NOTE1: Bits not defined in this table shall be cleared by the sending MME or SGSN and discarded by the receiving HSS.
NOTE2: If the MME is registered for SMS then the HSS will download the SMS related data also for the standalone MME.
