Revision Details	Release
In this release, SaMOG supports PLMN level statistics for Samog services.	21.23

Feature Description

The SaMOG level statistics that are available at the SaMOG system level does not allow operators pin-point issues to certain users of the network. PLMN-based statistics is captured and displayed in the CLI and bulk statistics to help operators localize failures to a particular circle. The PLMN-based statistics allows operators to decide on the load that is generated on the SaMOG from different circles and helps in network planning.

SaMOG extracts the PLMN information, such as Mobile Country Code (MCC) and Mobile Network Code (MNC) from International Mobile Subscriber Identity (IMSI) received in the Radius Access Request message.
SaMOG associates PLMN list to samog-services to enable the collection of PLMN level statistics for all the PLMN's present in the list.
Displays PLMN statistics in CLI through mandatory options of MCC and MNC.
Facility to clear the PLMN-based statistics for all PLMNs and for a specific PLMN based on MCC and MNC.
The PLMN statistics is applicable only for the combination of RADIUS Access-Request based triggers, EoGRE user-plane, Diameter-based authentication with AAA on STa interface and GTPv2 based S2A interface.
Displays PLMN level statistics of all the PLMNs in the samog-plmn schema bulk statistics.

Configuring PLMN-list

Use the following PLMN list command to capture the statistics at PLMN level. PLMN level statistics will be captured, only if the IMSI received during initial attach / Handoff belongs to one of the PLMNs in the associated PLMN list. By default no PLMN list is configured.

configure 
   context context_name 
      plmn-list plmn_list_name  
         mcc mcc_value  mnc mnc_value  
         end

plmn-list : Configures a list of PLMNs (MCC and MNC) and association to samog-service is required for capturing PLMN level statistics. A maximum of 25 PLMNs are allowed in a list. You can create a maximum of 10 PLMN lists for each context.
plmn_list_name : Enter a name of size 1 to 63
mcc mcc_value : Configures the PLMN MCC in the PLMN list. Enter a number, ranging from 100 to 999.
mnc mnc_value : Configures the PLMN MNC in the PLMN list. Enter a number, ranging from 00 to 999.

Note

List of MCCs with 3 digit MNCs are:

300 302 310 311 312 313 316 334 338 342 344 346 348 354 356 358 360 365 376 405 708 722 732

If you enter MCC, which is present in the above list, then MNC shall be of 3 digits. If you enter a 2-digit MNC for this case, then ‘0’ shall be prefixed to it and stored in the memory. When “show plmn-list name plmn-name” command is executed, then MNC with prefixed ‘0’ is displayed in the output.

Similarly, if user enters MCC which is NOT present in the above list, then MNC shall be of 2 digits. If user enters a 3-digit MNC for this case (with ‘0’ prefixed), then the prefixed ‘0’ shall be removed and stored in the memory. When “show plmn-list name plmn-name” command is executed, then MNC without prefixed ‘0’ is displayed in the output. If the entered MNC is more than 99, then error message is displayed.

For all other combinations, it shall be stored and displayed as it is.

Associate PLMN List to SaMOG Services

Use the following command to associate the PLMN List with the SaMOG service.

configure 
   context context_name 
      samog-service service_name  
         [ no ] associate plmn-list  plmn_value   
         end

Notes:

associate plmn-list plmn_value : Associates PLMN list with SaMOG services.
no : Dis-associates the PLMN List with SaMOG service and clears the existing PLMN statistics, if present for that PLMN

Removing PLMN List Configuration

Use the following command to remove the PLMN list. This command stops SaMOG or ePDG from capturing the statistics at PLMN level and clears the existing PLMN statistics if present for that PLMN.

configure 
   context  context_name 
      no plmn-list   plmn_name   
      end

NOTES:

no plmn-list plmn_name : Removes the PLMN list and stops the PLMN level statistics collection for that PLMN.

Add or Remove PLMN to or from PLMN list

Use the following command to add or remove PLMN to/from PLMN list.

configure 
   context  context_name 
      plmn-list   plmn_name   
           no  mcc   mcc_value mnc mnc_value 
           end

NOTES:

no mcc mnc : Removes PLMN entry with MCC and MNC combination from PLMN list. This commnad clears existing statistics if present for that PLMN.
mcc mcc_value mnc mnc_value : Adds or removes the PLMN entry.

Configuring samog-plmn schema

Use the following CLI commands to create new bulkstats schema for PLMN level statistics.

configure 
   bulkstats mode 
      [ no ] samog-plmn schema  schema_name [ active-only ] format format_string    
      end

samog-plmn schema : Configures SaMOG-PLMN bulk statistic schema.
schema_name alllows you to enter a string of size 1 to 31.
active-only : Gathers statistics on active chassis only.
format format_string : Designates naming convention format to use. Enter string of size 1 to 3599.
no : Deletes bulkstats schema for PLMN level statistics.

clear samog-service statistics

Use the following CLI commands to clear the PLMN based counters in SaMOG service for all the PLMNs or to a particular PLMN.

clear samog-service statistics  plmn all 
          clear samog-service statistics  mcc mcc_value mnc mnc_value 
          end

Notes:

clear samog-service statistics : Clears SAMOG service-related statistical information.
plmn : Clears SAMOG service-related statistical information at PLMN.
all : Clears the PLMN level statistics for all the PLMNs.
mcc : Clears the PLMN level statistics for this MCC followed by MNC of PLMN.mcc_value allows you to enter a number, ranging from 100 to 999.
mnc : Clears the PLMN level statistics for this MNC.mnc_value allows you to enter a number, ranging from 00 to 999.
