Abstract: Systems, methods, and computer-readable media are provided for displaying a digital map with scale information. In accordance with one implementation, a computer-implemented system is provided that includes a computer-readable medium that stores instructions, and at least one processor that executes the instructions. The processor receives a request for map data associated with a geographic area, and determines a viewport for displaying the map data on a user device. The processor also calculates a scale distance based on a measurement from the center of a first edge to the center of a second edge of the determined viewport. In addition, the processor provides, to the user device, the requested map data and instructions for displaying the map data, wherein the instructions include instructions to display a graphical element specifying the scale distance and a scale orientation in at least one of a horizontal or vertical direction.

Abstract: A system and method for controlling information transmission and communication handoff between frequency division multiplexing (FDD) and time division multiplexing (TDD) communication systems using any multiple access scheme is provided. The mobile unit transmits information via a current one of the FDD and TDD communication systems while it moves toward the other, or targeted one of the FDD and TDD communication systems. A pilot search signal is generated by the targeted communication system, where the pilot search signal corresponds to a transmission range of the targeted communication system. A communication handoff is initiated from the current communication system to the targeted communication system when the mobile unit recognizes a predetermined threshold level of the pilot search signal. Concurrent communications are synchronized and temporarily maintained between the mobile unit and both the current and targeted communications systems using an increased data rate for each of the communications links.

Abstract: A method and apparatus for controlling the transmission power of a mobile station during handoff of a call between base stations of a cellular system A desired transmission power of a mobile station on an assigned traffic channel of a target base station is determined, and the transmission power of the mobile station is adjusted over a range of power values to be set to the desired transmission power level. The desired transmission power of the mobile station may be determined based on measurements made on the pilot channel of the target base station at the mobile station.
