GeoLENs™ GeoLocation-Enabled Network Solutions—Policy Server

The Andrew GeoLENs Policy Server is a powerful tool for controlling access to, and the quality of location information in both IP and cellular location enabled networks. By controlling who can access location and at what quality, the Andrew GeoLENs Policy Server permits the operator to maximize control of, and ROI on, their location infrastructure investment.

In SUPL deployments the Policy Server works in conjunction with an Operator’s SLP to restrict SET initiated requests to mobile devices that have paid for a location capability. The Policy Server can be deployed as a stand-alone platform containing all the subscribers allowed to use SET initiated location requests. In this mode the Policy Server can maintain up to 70 million subscriber records and be queried by a number of geographically distributed SLPs. The Policy Server supports multiple arbitration outcomes including:

Acceptance, full location rights
Rejection, no location rights
Partial, a coarse location is provided

In addition to maintaining a subscriber database, the Policy Server can also query external operator policy sources in order to confirm a client’s right to access location information. External policy sources include Diameter, RADIUS and LDAP servers. When used in this manner the Policy Server may be internal or external to the SLP.

For smaller operators the option also exists for a limited capacity subscriber database to reside in the integrated SLP-Policy Server configuration.

The Policy Server is also an element of the GeoLENs LIS product portfolio. In the LIS, the Policy Server can be used to interrogate external policy servers, such as a RADIUS, Diameter and LDAP server to ascertain a user’s right to quality location information. The Policy Server can be configured to apply local jurisdiction and operator policies pertaining to specialist location clients. Agencies such as law enforcement and emergency services can obtain high accuracy location information for any device. Policies can be applied to both Targets and third party location requestors.

The Policy Server also enforces Target policies associated with HELD contexts. These policies may contain IETF common policy documents (RFC4745), geo-policy documents (draft-ietf-geopriv-policy-20), or a combination of the two.

The Andrew GeoLENs Policy Server provides operators with the controls and flexibility needed to manage and enforce location policy in their network. Operating as either a standalone or integrated element to existing Andrew GeoLENs location products the Policy Server adds real value to a location enabled network.
