Goal

This document explains why a location update may be successful in Hlr even when the Vlr address is missing in the OCPLMN template.

Solution

Whenever LU request is received from PLMN which is not defined in our HLR,Hlr Checks the default PLMN. A default PLMN is created at system start up. This default PLMN doesn’t have any VLR/GMSC nodes associated to it.

In the case of the ‘Default PLMN’, the Node Range list is empty (N/A), which means that for all Node Ranges the roaming Allowed/Not Allowed verification will be done based on the Allowed IMSI defined for the ‘Default PLMN’ assigned to the subscriber’s OCPLMN Template.

The “Allowed IMSIs list” may:

  1) Be empty (N/A) – this means that the “PLMN is NOT allowed “.Any calls coming from any Node Range defined for that PLMN will be blocked.
  2) Have a list of one or more specific IMSI ranges.This only allows certain subscribers (IMSIs) to make calls from any Node Range defined for that PLMN.
  3) Have a MCC=000 and MNC=000 as IMSI ranges.This allows ALL subscribers (IMSIs) to make calls from any Node Range defined for that PLMN.
