IMSI detached flag is a parameter indicating that the MS is in the IMSI detached state, i.e. the subscriber is no longer reachable. For definition and handling see
TS 23.012 and
TS 29.002. The parameter takes the following values:
-
IMSI detached;
-
IMSI attached.
The parameter is temporary subscriber data and is stored conditionally in the VLR.
In HLR, MNRG indicates whether the MS is marked as GPRS detached or GPRS not reachable in the Gn/Gp-SGSN and possibly in the GGSN. The reason why the MS is GPRS not reachable is indicated in the Mobile Not Reachable via SGSN Reason (MNRR-SGSN).
In Gn/Gp-SGSN, MNRG indicates whether activity from the MS shall be reported to the HLR.
In GGSN, MNRG indicates whether the MS is marked as GPRS detached in the Gn/Gp-SGSN.
MNRG is described in
TS 23.060. It is temporary subscriber data stored in the HLR, in the Gn/Gp-SGSN and in the GGSN.
The Mobility Management State indicates the GPRS state of the MS. It takes one of three possible values:
-
READY: The MS is GPRS attached and its location is known at Cell Identity level.
-
STANDBY: The MS is GPRS attached and its location is known at Routing Area level.
-
IDLE: The MS is not GPRS attached.
The parameter is described in
TS 23.060. It is temporary subscriber data stored in the SGSN.
In the case of SGSN, MME, VLR or HLR failure, location register data have to be restored as described in
TS 23.007 and
TS 29.002. The following flags are used for this purpose.
Confirmed by Radio Contact indicator is a restoration indicator defined in
TS 23.007.
It is temporary subscriber data, stored in the VLR.
Subscriber Data Confirmed by HLR/HSS indicator is a restoration indicator defined in
TS 23.007.
It is temporary subscriber data, stored in the VLR, in the SGSN and in the MME.
Location Information Confirmed in HLR/HSS indicator is a restoration indicator defined in
TS 23.007.
It is temporary subscriber data, stored in the VLR and in the SGSN and in the MME.
Check SS indicator is a restoration indicator defined in
TS 23.007.
It is temporary subscriber data and is stored in the HLR.
VLR-Reliable indicator is a restoration indicator defined in
TS 23.007.
It is temporary subscriber data and is stored in the SGSN and in the MME.
MS purged for non-GPRS flag is set in the HLR per IMSI record in order to indicate that the subscriber data for the MS concerned have been purged in the VLR. The parameter takes the following values:
-
MS purged;
-
MS not purged.
The default value is
"MS not purged". The parameter is temporary subscriber data, stored in the HLR.
MS purged for GPRS/UE purged in SGSN flag is set in the HLR/HSS per IMSI record in order to indicate that the subscriber data for the MS/UE concerned have been purged in the SGSN. The parameter takes the following values:
-
MS purged for GPRS/UE purged in SGSN;
-
MS not purged for GPRS/UE not purged in SGSN.
The default value is
"MS not purged for GPRS"/
"UE not purged in SGSN". The parameter is temporary subscriber data, stored in the HLR/HSS for a PS subscription.
UE purged in MME flag is set in the HSS per IMSI record in order to indicate that the subscriber data for the UE concerned have been purged in the MME. The parameter shall take the following values:
-
UE purged in MME;
-
UE not purged in MME.
The default value is
"UE not purged in MME". The parameter is temporary subscriber data, stored in the HSS for a PS subscription.
Mobile station Not Reachable via MSC Reason (MNRR-MSC) for SMS is defined in
TS 23.040.The MNRR-MSC is temporary subscriber data. It is conditionally stored in the HLR.
Mobile station Not Reachable via SGSN Reason (MNRR-SGSN) for SMS is defined in
TS 23.040.The MNRR-SGSN is temporary subscriber data. It is conditionally stored in the HLR.
Subscriber data dormant is set in the VLR per IMSI record in order to indicate that the subscriber data belong to a subscriber that has moved outside the VLR area (see
TS 23.012). The parameter takes the following values:
-
Subscriber data dormant;
-
Subscriber data not dormant.
The parameter is temporary subscriber data and is stored in the VLR.
Cancel Location received is set by a VLR supporting the MT roaming retry feature per IMSI record to indicate that a Cancel Location message has been received from the HLR. This is used to determine whether to trigger MT roaming retry upon receipt of an incoming call, see
clause 7.3.2.1 of TS 23.018. The parameter takes the following values: true or false.
The parameter is temporary subscriber data and is stored in the VLR.
The UE Reachability Request Parameter for the MME (URRP-MME) indicates that UE activity notification from MME has been requested by the HSS. For definition and handling of the data see
TS 23.401.
URRP-MME is temporary subscriber data conditionally stored in the MME and in the HSS.
The UE Reachability Request Parameter for the SGSN (URRP-SGSN) indicates that UE activity notification from SGSN has been requested by the HSS. For definition and handling of the data see
TS 23.060.
URRP-SGSN is temporary subscriber data conditionally stored in the SGSN and in the HSS.
This information element is a list of service related entities (i.e. gsmSCF address list or AS Identity list, see the definition of gsmSCF address list in
clause 2.14.2.4 and the definition of AS Identity list in
clause 3.5.7) which have subscribed to a notification of UE reachability (e.g. IP-SM-GW )
Service-related Entity list is temporary subscriber data stored in the HSS.
