Number Management System

Number management System is an inventory management system for telephone numbers and other customer numbers
An open, scalable, centralized database with all the functionality carriers need to store, manage, and assign wire line and mobile telephone numbers and for a multitude of services
Using one centralized database for all numbers, it eliminates redundancies and errors, manages the most complex number requests, and provides instant access to accurate, continuously-updated, criteria-sorted number information.
 

Why Number Management System ?

• Preventing duplicate number assignments
• Improving customer service by providing instant access to accurate number data during service negotiation and utilizing threshold tracking and alarming
• Integrating easily with other number management and business systems
• Automating wire line and Mobile Number Portability business flows
• Providing support for SIM and IMSI management

 

SIM Management System

The application takes care of maintaining an audit-trail of the transactions carried out by the counter operators/ accounts officers – of each SIM-card issue, Sale of SIM card/ recharge card, replacement, blocking of GSM number, cancellation of receipt, reprinting of receipt, surrendering connection, release of surrendered connection for sale, waiving of charges, etc.
History of transactions can be viewed by Administration and Management whenever necessary.
 

SIM Provisioning

Provisioning Statuses
Create, Idle, Failed, Active, Suspended, Disabled, and Recycle statuses.
SIM Generation
Generates the SIMs numbers and creates a file for sending to the supplier and to the ERP system.
New Number Configuration
Configures a set of MSISDNs with various parameters to provision later.
Bulk MSISDN Number Provisioning
Associates a range of MSISDNs with a contiguous range of SIMs and provisions these through the provisioning system.
Number Recycling
Deletion of the recycled numbers on the IN and HLR and VMS.
Re-provision Numbers
Search of recycled numbers to be reconfigured and re-provisioned.
Configure Memorable Numbers
Individual or patterned numbers can be assigned to a pool so they cannot bulk be provisioned but are saved for individual provisioning by customer selection with a customer service request.
 

SIM/Number Management(NM)

SIM Ordering
Make requests through an NM System to generate a purchase order for one or more batches of SIMs.
Goods Inwards
The SIM supplier supplies, in a file for each IMSI/ICCID, the following data that is then associated to the original record: MSISDN (Optional), IMSI1, IMSI2, ICCID, PIN1, PUK1, PIN2, PUK2, Authentication Key.
Goods Outwards
Stock is taken from the warehouse to goods outwards, located in the system and updated from Reserved to Delivered, and then physically moved from the warehouse to the delivery/shipping company.
Returns – Damaged Stock
Items can be returned and flagged when they are faulty.
 

FNN / MSN Life cycle

Billing solution provides a service lifecycle model and the management of subscriptions (MSISDNs) within that life cycle the following lifecycle states used in the solution and a MSISDN will always be in one of these states:

• Available – A number in the inventory begins in available status, ready for regular number selection process to find and provision.
• Pre-Active / Assigned – The subscription state where the number is selected and provisioned through provisioning system but is not yet “Active”
  
• Active – Upon provisioning completion, the number moves to Active status. The number remains in this status until the customer no longer needs it. Switch will allow subscribers to originate events (voice calls, send SMS-MO, MMS, receive SMS-MT etc) in this state (assuming sufficient balance etc to rate the event).
• Inactive – The subscription state when the account balance is less than or equal to zero (due to subscriber or customer care activity) but neither the Active nor Life time timers have expired. The subscriber can only originate calls to the IVR. For example the subscriber has not used all of their active time since the last recharge (e.g. still 20 days left) but they have zero balance. 
• Deactive – The subscription state when the Active timer but not the Lifetime timer has expired. The subscriber can only originate calls to the IVR. For example, the subscriber has used all of their active time (e.g. more than 186 days). Once the subscriber performs a recharge they will move back to the Active state and the active time will start again.
• Expired – The subscription state when the Lifetime timer has expired. Subscribers will exist indefinitely in this state on the network switch until a request is received from the customer service request to erase the subscriber or Reactivate the account (which will change the state from “disconnected” to “Deactive”). For example, more than 1272 days have passed since the subscriber’s last successful recharge.
• Unavailable – A number that has been given to another service provider or is otherwise not available for selection has the status of unavailable.

 

Lifecycle of prepaid SIM

• Prepaid packaged SIMs can be assembled with a dummy MSN or real MSN at the time of loading to Number management system. An assembly is created when SIM and MSN is paired
• At registration when the SIM is activated, the relationship between an active SIM and its associated real MSN is maintained in Number management system.
• The assembly meets the requirement to couple the MSN and SIM packaged in prepaid packs until either cancellation by a customer or shelf life expiry occurs. There are 2 processes, dependent on the initial pairing of a dummy or real MSN for bulk activation.
• On cancellation of service, the SIM remains in Aging status for 180 days before the same is moved to Unavailable status
• Life cycle of postpaid SIM is similar to that of prepaid SIM
• Unlike prepaid SIMs, postpaid SIMs need not be bulk activated in the networks
• On cancellation of service, the SIM remains in Aging status for 180 days before the same is moved to Unavailable status
