Subscriber Management
- About Subscriber Management
  Subscriber Management provides an overview of subscriber-related data, including users, groups, subscriptions, devices, balances, and notifications. You can capture any attribute of a subscription and base rating on it, enforce subscription and group spending limits across all services and networks, and notify users associated with subscriptions and groups when the subscriptions and groups are nearing spending limits.
- Subscriber Authorization
  MATRIXX Engine supports service authorization and cut-offs to ensure subscriber usage is valid and revenue loss does not occur.
- Subscription-User Association
  You can associate a _glossary/subscription.html with a user in a many-many relationship using the user APIs.
- Subscription-Device Association
  When a network message is received, the device information is used to guide the service usage to the subscription. As a result, a subscription can have any number of associated devices.
- Managing Subscriptions
  Managing subscriptions includes adding subscriptions to groups, removing subscriptions from groups, setting the status of subscription objects, and associating users with subscriptions. You can perform these operations by using MATRIXX Backoffice Customer Tool and any custom applications that call the SubMan APIs.
- Managing Devices
  You can create, provision, and delete devices by calling the SubMan APIs and scheduling automated tasks.
- Managing Users
  Managing users includes creating and deleting users, associating users with subscriptions, and assigning users roles. You can perform these operations by using MATRIXX Backoffice Customer Tool and any custom applications that call the SubMan APIs.
- Managing Product Offers
  Managing product offers includes purchasing and canceling product offers, and removing expired product offers. You can purchase and cancel product offers by using MATRIXX Backoffice Customer Tool and any custom applications that call the SubMan APIs. Expired product offers are removed from subscriber and group wallets automatically after a configured amount of time.
- Rehoming
  Rehoming is the process of moving a user, group, device, or subscription from one sub-domain to a different sub-domain in a multi-domain platform.

Subscription-User Association

You can associate a subscription with a user in a many-many relationship using the user APIs.

During subscriber database configuration, you can define the following information that impact user objects:

How many users would you like to support?
What is the average size of a user object in bytes?
What is the initial size of a user object in bytes?
How many userSubscriptionJoin objects do you want to support?
What is the average size of a userSubscriptionJoin object in bytes?
What is the initial size of a userSubscriptionJoin object in bytes?
How many userGroupJoin objects do you want to support?
What is the average size of a userGroupJoin object in bytes?
What is the initial size of a userGroupJoin object in bytes?

For more information about subscriber database configuration, see Installation and Configuration.

In general, a subscription should be associated with a user. For information about the subscription APIs, see the discussions about subscription APIs. For information about the user APIs, see the discussions about the user APIs.
