Destination context 

Specifies the name of a configured destination context through which the subscriber is provided 
access to the packet data network. 

Accounting context 

Specifies the name of a configured accounting context through which the subscriber is provided 
accounting of data session. 

Subscriber Plmn Type 

Indicates the subscriber type of Public Land Mobile Network area. Possible values are: 
- H: Home networks 
- F: Foreign networks 
- U: Unknown networks 

Charging Characteristics 

Displays the Charging characteristics. Hot Billing, Flat rate Billing, Prepaid Billing and Normal 
Billing 

Charging Characteristics 
Selection Mode 

Displays the selection mode of the Charging characteristics. 

MNRG Flag 

The MNRG (Mobile Not Reachable for GPRS) flag indicates whether activity from the MS will be 
reported to the HLR or not. Possible values are True or False. 

PPF 

The PPF (Page Proceed Flag) indicates whether paging for PS and CS services can be initiated. 
Possible values are True or False. 

NGAF 

The NGAF (Non-GRPS Alert Flag) indicates whether activity from the MS will be reported to the 
MCSC/VLR. Possible values are True or False. 

VLR-Reliable 

Set to 'false' when the SGSN has received a reset indication from the VLR. The SGSN may request 
the MS, upon reception of the next routing area update (either periodic routing area update or 
combined routing and location area update) procedure, to re-attach to non-GPRS services if the MS 
is still IMSI attached to non-GPRS services. Alternatively, the SGSN may upon reception of a 
combined routing and location area update request or a periodic routing area update from a MS that 
is still attached for non-GPRS service, perform immediately the location update for non-GPRS 
services procedure. 

VLR-Association 

States associated to the Gs interface in the VLR. Possible states are: 
- Gs-NULL 
- LA-UPDATE PRESENT 
- Gs-ASSOCIATED 

NRI Assigned 

The Network Resource Identifier (NRI) is used either when Iu-flex or Gb-flex is used or when 
MOCN configuration is used for network sharing. NRI is a 1-10 bit length value that is a part of 
PTMSI. This de-multiplexes which SGSN handles the subscriber at the RNC or BSS. The NRI that 
was chosen for this subscriber is shown and this is useful to know when this SGSN is configured 
with more than one NRI.
