摘要： Each cell has an assigned classification that determines its inclusion in a measurement list for handing off. The candidate cells, which are selected from the measurement list are given priority level assignments. The priority levels are implemented by the candidate neighboring cells measured RF signal strength; and the order of handing off is arranged in accordance with the adjusted RF signal strength.

摘要： A method and system for handing off an on-going communication from a serving cell to a neighboring cell of a cellular communication system having scanning receivers associated with each base transceiver station. A dynamic threshold is calculated for effecting the handoff in accordance with various operating conditions. The current mobile minimum attentuation level, (MT) the minimum permissible attenuation level of a serving (MS) cell and a neighboring cell (MN), together with the RF signal strength of the mobile unit at the neighboring cell (RSSI-NBR) and the serving cell (RSSI-SRV) are used in calculating a dynamic threshold (RSSI-THP).

摘要： Cellular handoff is improved by tailing or adapting the measurement time based on the characteristics of the received signal intensity or power. More particularly, base stations typically measure mobile signal power in order to determine the necessity for handoff and the identity of a new cell. The measurement time must be of a duration which is sufficient to characterize the environment of the mobile. In accordance with the invention, the duration of the measurement time is determined from the received signal itself. Once the duration of the measurement time is determined, that data may be passed to a target cell along with other handoff data.

摘要： A method and system which temporally sorts data such as program guide data for example, to ensure that near-term data (i.e. most likely to be used, or “now data”) is always available for rapid access from a physical memory location such as a high-speed temporal cache. The method incorporates two low-priority background processes or algorithms, termed “event horizons” into the storage and manipulation of the data so that applications using the data may be run without having to always access a mass storage device. The method and system are highly applicable to all set top boxes (STBs) used in various communication systems such as satellite communication, Cable-TV and DVB systems. The method and system are economical in that superior STB and/or system performance may be obtained with the inclusion of lesser amounts of expensive high-speed RAM.
