  • System and method for inferring wireless trajectories in a cellular telephone network
    Patent number: 8121599
    Abstract: A device includes a processor configured to determine a number of users in each of a plurality of wireless telephone cells of a trajectory in a wireless telephone network. The processor is also configured to determine handoff data between each adjacent pair of the wireless telephone cells, and to determine a first number of users traveling along the trajectory in the wireless telephone network while on a telephone call. The processor also calculates a total number of users associated with the trajectory in the wireless telephone network based on the handoff data between each adjacent pair of the wireless telephone cells, and based on the first number of users traveling along the trajectory while on the telephone call.
