In the above example, assume that when CDR is opened the subscriber is in CGI1. The first
container is closed because of QOS change and second container is closed because of Tariff Time.
Now the ULI is changed to CGI2. Third container includes the indication of location change (ULI
change to CGI2) and corresponding volume counts before the location change and after the tariff
time change. Now these three containers does not have the “User Location Info” because none of
the containers are closed with CGI/SAI change or RAI change. Now if the fourth container is
closed it should have a User Location Info as CGI2. This is because the previous change condition
was CGI/SAI change and hence the next container should have new ULIs (CGI2).
