Annexure IV

VLR Subscribers in the Wireless Segment



Home Location Register (HLR) is a central database that contains details of
each mobile phone subscriber that is authorized to use the GSM core network.
The HLRs store details of every SIM card issued by the mobile phone operator.
Each SIM has a unique identifier called an International Mobile Subscriber
Identity (IMSI), which is the primary key to each HLR record. The HLR data is
stored for as long as a subscriber remains with the mobile phone operator.
HLR also manages the mobility of subscribers by means of updating their
position in administrative areas. It sends the subscriber data to a Visitor
Location Register (VLR).



Subscriber numbers reported by the service providers is the difference
between the numbers of IMSI registered in service providers Home Location
Register(HLR) and sum of other figures as given below:-


                1             Total IMSI's in HLR (A)

                2             Less: (B=a + b + c + d + e)


                a.            Test/Service Cards


                b.            Employees

                              Service suspended pending
                e.            disconnection


                3             Subscribers Base (A-B)




                                    17
Visitor Location Register (VLR) is a temporary database of the subscribers
who have roamed into the particular area, which it serves. Each base station
in the network is served by exactly one VLR; hence a subscriber cannot be
present in more than one VLR at a time.



If subscriber is in active stage i.e. he is able to send/receive calls/SMSs he is
available both in HLR and VLR. However, it may be possible that the
subscriber is registered in HLR but not in VLR due to the reason that he is
either switched-off or moved out of coverage area, not reachable etc. In such
circumstances he will be available in HLR but not in VLR. This causes
difference between subscriber number reported by the service providers and
numbers available in VLR.



The VLR data calculated here is on the basis of active subscribers in VLR on
the date of Peak VLR of the particular month for which the data is being
collected. This data is to be taken from the switches having the purge time of
not more than 72 hours.

  • 17. Annexure IV VLR Subscribers in the Wireless Segment Home Location Register (HLR) is a central database that contains details of each mobile phone subscriber that is authorized to use the GSM core network. The HLRs store details of every SIM card issued by the mobile phone operator. Each SIM has a unique identifier called an International Mobile Subscriber Identity (IMSI), which is the primary key to each HLR record. The HLR data is stored for as long as a subscriber remains with the mobile phone operator. HLR also manages the mobility of subscribers by means of updating their position in administrative areas. It sends the subscriber data to a Visitor Location Register (VLR). Subscriber numbers reported by the service providers is the difference between the numbers of IMSI registered in service providers Home Location Register(HLR) and sum of other figures as given below:- 1 Total IMSI's in HLR (A) 2 Less: (B=a + b + c + d + e) a. Test/Service Cards b. Employees Stock in hand/in Distributional Cannels (Active Card) c. Subscriber Retention d. period expired Service suspended pending e. disconnection 3 Subscribers Base (A-B) 17
  • 18. Visitor Location Register (VLR) is a temporary database of the subscribers who have roamed into the particular area, which it serves. Each base station in the network is served by exactly one VLR; hence a subscriber cannot be present in more than one VLR at a time. If subscriber is in active stage i.e. he is able to send/receive calls/SMSs he is available both in HLR and VLR. However, it may be possible that the subscriber is registered in HLR but not in VLR due to the reason that he is either switched-off or moved out of coverage area, not reachable etc. In such circumstances he will be available in HLR but not in VLR. This causes difference between subscriber number reported by the service providers and numbers available in VLR. The VLR data calculated here is on the basis of active subscribers in VLR on the date of Peak VLR of the particular month for which the data is being collected. This data is to be taken from the switches having the purge time of not more than 72 hours. --------- 18
