Of the 45 patents added to TCS' portfolio, the following eight are indicative of their depth and relevance:
-The recently issued Personal Location Code patent (U.S. Patent 8,428,619), a continuation of patents 7,957,751 and 8,165,603 that were issued in previous years, is an LBS patent that describes techniques that allow mobile device users to control access to their location information through the use of a PLC. By implementing a PLC, the user can customize the access of the user's location information by another individual or application. For example, if you are expected at a meeting, you can allow others to track your travel progress to that meeting. A PLC does not reveal any identification information about the user and establishes parameters that determine who can locate a user, in addition to how and when a user can be located. A PLC can be made to expire due to time, geographic location or other parameters. Location Based Services can use PLCs to constrain the use of a user's location and can be conveyed either via proprietary techniques or use standard messaging, chat, and instant messaging protocols.
-The recently acquired System and Method for Determining the Location of a Mobile Device patent (U.S. Patent 8,378,888) is an LBS patent that describes a system and method that sends time-stamped information from a mobile device to a Mobile Location Center wherein the platform produces the calculated location of the mobile device. This location method is described in later-released LTE standards and may serve as the foundation for LBS services in an LTE network.
-The recently acquired System and Method for Preventing A-GPS Devices from Searching for Specific Satellites patent (U.S. Patent 8,085,193) is an LBS patent that describes a system and method that reduces the number of satellites that a device needs to search and acquire in order to calculate its location. By marking "healthy" satellites as being "unhealthy," the amount of power and time needed to generate a location calculation can be reduced, thus extending battery power and reducing the time to get a satellite-based location fix. This technique can extend the battery life of devices that use GPS-intensive applications and can speed up the time-to- first-fix, thereby improving user interfaces and response times.
-The recently acquired Using Serving Area Identification in a Mixed-Access Network Environment patent (U.S. Patent 8,019,339) is an LBS patent that describes a system and method that allows two LBS location-calculation techniques, Control Plane and User Plane, to cohabitate within a specific platform. In a typical Control Plane architecture, an outside entity may request the location of a mobile device. In a typical User Plane architecture, the request for the location of a mobile device starts with the mobile device. As LBS applications continue to proliferate, a wireless carrier is more and more likely to need platforms that support both Control Plane and User Plane technologies. Being able to support both technologies within a single platform provides economies of scale and a competitive advantage to the vendor providing such a combined system.
