ABSTRACT

Presented herein are systems for cell identification (ID)-based location tracking.

This platform may be integrated into the Internet of Things (IoT) ecosystem for customer

2G/3G/4G devices hosted in a Home Location Register (HLR) / Home Subscription

Server (HSS).

DETAILED DESCRIPTION

There are many applications and services that would benefit from having a

ubiquitous location tracking mechanism for a subscriber even when there is no available

Global Positioning System (GPS) or mobile data connection. The mobile network is

already tracking the location of the user in order to provide its services. The tracking is

normally only used by the network, but other applications also benefit from this

knowledge. Some example applications include: fleet management services to track

inventory units/vehicles; tracking mobility patterns of children, the elderly, and pets to

build maps of mobility; and a range of new services such as targeted advertising,

determining geographic areas visited by certain demographics, or locating a lost device

(e.g. a phone). Described herein are systems for cell identification (ID)-based location

tracking that are more ubiquitous than other systems/methods (e.g., Wi-Fi® positioning).

As an example, the operator may potentially use three methods to obtain a cell ID:

Location Services (LCS), GPS hardware, and cell ID-based location tracking.

1. LCS: This is a specific feature provided in the Mobile Application Part (MAP)

protocol to obtain user cell location information in order to provide location-based

services. While LCS is relatively accurate, it requires specific dedicated nodes on the

network level, such as a Gateway Mobile Location Center (GMLC) and/or a Serving

Mobile Location Center (SMLC), for position calculations. LCS methods are fairly

unpopular due to the entry of GPS and phone-based applications for location tracking.

2. GPS Hardware: GPS hardware located on the end device may be coupled with a

subscriber identity module/device/device operating system (OS) application in order to

extract the location of the device. GPS hardware is also relatively accurate, but because

many devices are already deployed without the GPS hardware, this methodology would

require new devices to be issued or existing end device hardware/software to be

upgraded. Installation and deployment of this GPS hardware/software is difficult and

expensive. For example, this would require a bulk recall of the deployed devices.

3. Cell ID-Based Location Tracking: Unlike GPS, which is a satellite-based service,

cell coverage is a terrestrial tower-based system. As such, cell coverage is more reliable

than GPS service in certain situations (e.g., on cloudy days, underground, inside

buildings, etc.). In an example, systems described he...
