A wireless communication service network includes a message processing system with at least two programmable application processors (APs) providing operational, administrative and maintenance support for one or more cell base stations in the network serving one or more wireless radio units. Improved control of the AP message processing resources is provided in response to an AP shutdown condition. In accordance with the improvement, an initial overload control (OLC) threshold is set for the APs, and the APs are monitored during their operation as they perform message processing. In the event that one of the APs becomes non-operational (non-operating AP), the OLC threshold relative to one or more remaining operational APs is dynamically increased. The message processing functions of the non-operational AP are then redistributed to one or more remaining operational APs, whereby improved load sharing is provided among the remaining operational APs and the likelihood of a catastrophic processing failure is minimized.
The invention relates to a device and a procedure for aiding the management of a wireless telephony network consisting of stations. The procedure comprises, for a given mobile pertaining to a station:a--the calculation of a quantity incorporating the attenuation with regard to its station and the attenuation with regard to the neighboring stations (103),b--the product of this quantity times another quantity representing the requirements of the mobile with regard to its station (103),c--the summation of these products for a given set of mobiles pertaining to said station (105),d--the comparison of the sum with a threshold (107).
This invention relates to a method and apparatus for controlling application processor occupancy based traffic overload. More particularly, the invention is directed to a system to maintain call processing related traffic below a predefined threshold in application processors that are typically incorporated into communication networks.
A satellite communication system (10) includes a satellite (20) which receives first and second data from sources. Each satellite receives control data from a satellite control center (100). An earth processing center (PC) is arranged to process the data received from the satellites, and a wide band network (30) is arranged to transmit the data to the processing center. A receptor terminal (A) is arranged to receive the first data and to place the first data on the network (30) for transmission to the processing center (PC). A second receptor terminal (B) is arranged to receive the second data and to place the second data on the network (30) for transmission to the processing center (PC).
A mobile communication system which includes an exchange, a plurality of base stations, and a plurality of radio telephone sets communicatable with the associated base stations. In order to suppress or reduce call loss caused by traffic congestion or by faulty one of the base stations, an uncommunicatable service area of the faulty base station is covered by the other working base stations. The exchange detects operation states of all the base stations, searches a base-station state pattern table within the exchange for base-station control data suitable for the operation states to read out the base-station control pattern, and transmits the read-out base-station control data to the base stations to cause radio service areas of the base stations to be set to have desired radiation patterns according to the read-out base-station control data.
Disclosed herein is a method and system for managing transmission of media to a plurality of subscribers. As a general matter, a media management system determines that a more than a threshold number of subscribers scheduled to receive a given media transmission are located within a common zone (e.g., common wireless coverage area, common geographically-defined area, etc.), and the system responsively (i) divides the subscribers in the common zone into two or more groups and (ii) transmits the media to the groups sequentially. Preferably, the system waits a period of time between transmission to each group.
