When TR-069/TR-369 USP and Location Based Services Meet

Smart use of insights acquired from a mobile network enriched data in combination with the TR-069/TR-369 USP device data can help service providers optimize their services, increase ARPU and identify potential service degradations and trends that should be closely monitored.

A location-based service (LBS) is a service provided based on the geographic location of the Device or information related to the Device location. LBS data tied to a specific area where activities take place can offer service providers a variety of features for optimized subscriber management.

LBS emerged in the 1990s with the development of the Internet, global positioning, and the use of mobile devices.

A wide range of services can be offered based on LBS mapping and navigation, such as search and information, social networking and entertainment, recreation and fitness, as well as tracking.

In this post, we have outlined a few use-cases that describe how LBS can be leveraged for early identification of disruptive service patterns and prevent abuse of the CSP's subscriber plans.

  • Fraud prevention
    • Avoid the misuse of customer devices if moved to a different location outside of the home network zone.
  • Tariff change
    • Change and update customer tariffs according to the Subscriber's location
  • Zone related information – send notifications to the residents of a specific area if any area-related problem is detected.
    • Enrich customer metadata with additional zone related information that can be used by 3rd party application to send or push zone related data
  • Defining zone-related performance KPI
    • Proactive monitoring of KPI related to different location zones
    • Going from passive notification of service failure to predictive insights on service degradation
    • Troubleshooting zone-related events for fast and precise failure diagnostics
  • Predictive analytics based on zone-related KPI
    • Area-based heatmaps, e.g., if a certain amount of subscribers in a specific area experience a DL/UL ratio of less than 100MB, the CSP can offer an upgrade to its customers.


LBS and TR-069/TR-369 USP Mechanism

Here is a brief overview of a scenario combining mobile network enriched data in combination with the TR-069/TR-369 USP device data.There are two ways to detect a change in the Device location.

  1. IP Geolocation
  2. Device Geolocation parameters – for supported devices with built-in GPS functionality, location parameters can be used to set the customer location zone.
  3. Mobile Network enrichment parameters
    • For devices with cellular network modules, the supported parameters could help determine the device zone according to network layout and design, e.g., Cell ID. Any change in Serving Cell ID can be identified and matched to the Home Zone configuration.
    • A change in Cell ID will indicate that the Device has been moved from one Serving Area to another.
    • Upon a change in the Serving Zone, a new configuration file can be sent to the Device.
    • The configuration file will change the default parameters to set the Device to a "Closed Garden" environment.

We are matching the IP Address with the location of the Device connected to the Internet. Geolocation involved in IP mapping uses the following parameters: country, region, CSP, or domain name.There are some significant disadvantages of IP based geolocation for TR-069 connected devices that are mainly related to the lack of accuracy of IP-based geolocation.

Network zoning

  • Network zoning is used to apply service access conditions depending on the location of a mobile subscriber.
  • The following areas are considered network zones:
    • Home Zone – The area of a network in which a subscriber is registered.
    • Home Network – The entire network in which a subscriber is registered.
    • Roaming – If the Subscriber is located in neither Home Zone nor Home Network, he is considered to be Roaming
  • The Home Zone in which the Subscriber is registered can be defined according to the Subscriber's Address, Serving Area Network, or SIM credentials
  • Upon a change of zoning parameters (change in Cellid), a network operator can decide on a rule applied to the Device – e.g., service restriction or a subscriber plan change.
  • When the Device moves from the Serving Zone, it informs the ACS of a Zone Parameter change, forcing the ACS to push a configuration file to the Device, based on a rule that the Service provider has assigned to this type of event.
  • When the Device is back in the Serving Zone, it runs the re-provision process, which restores the Device to a normal operation mode


Home Zone

Communication between the ACS and the Device

Normal usage - the Subscriber uses an APN to access the Internet.


Communication between the ACS and the Device when the Device Location changes

  • When the Device moves from the Serving Zone, it informs the ACS of a Zone Parameter change, forcing the ACS to push a configuration file to the Device, based on a rule that the Service provider has assigned to this type of event.
  • When the Device is back in the Serving Zone, it runs the re-provision process, which restores the Device to a normal operation mode
