摘要： Disclosed herein is a method that enables a radio access network (RAN) to page more mobile stations concurrently. By reducing the size of the individual page record, more page records can fit within a general page message (GPM), and thus more mobile stations can receive page messages. One method of reducing the size of an individual page record is to reduce the size of the terminal IDs that page records carry. Currently, terminal IDs are globally unique, but they can be shortened if replaced with locally unique IDs. These locally unique IDs are unique for only mobile stations in a given paging area, unique for only mobile stations assigned to a given paging channel time slot, and/or unique for only mobile stations in a subgroup of mobile stations assigned to a given paging channel time slot. The number of mobile stations in any of these groups is smaller than the number of mobile stations in the global network. Therefore, the length of a terminal ID that is unique for only mobile stations in one of these groups can be shorter than a globally unique identifier.

摘要： A privacy-preserving device-tracking system and method to assist in the recovery of lost or stolen Internet-connected mobile devices. The function of such a system seem contradictory, since it is desirable to hide a device's legitimately-visited locations from third-party services and other parties to achieve location privacy, while still enabling recovery of the device's location(s) after it goes missing by tracking the device to determine its location. An exemplary embodiment uses a DHT for storing encrypted location information and other forensic information in connection with indices that are successively determined based on initial pseudorandom seed information (i.e., state) that is retained by the owner of the device. Using the seed information, the software can determine indices mapped to location information stored after the device went missing, enabling the device to be located. Numerous extensions are discussed for the basic exemplary design that increase its suitability for particular deployment environments.
