Abstract:
A method and system for distributing a plurality of data processing units (116, 118, 120, 122, 124, 126, 128, 130 and 132) in a communication network (100) is provided. The communication network comprises a plurality of manager data processing units (104, 106 and 108) for serving the plurality of data processing units. The method includes detecting (304) a failure at a manager data processing unit of the plurality of manager data processing units. Further, the method includes distributing (306) the plurality of data processing units to remaining manager data processing units of the plurality of manager data processing units.
Abstract:
An automatic protection arrangement for a communication system (100) provides a working line terminal equipment (300 and a link (1A) for transmitting bearer traffic from a number of bearer payload processors (50-N) to a switching center (10). The arrangement also has a protection line terminal equipment (35) and link (2A) coupled to the switching center (10). For detected faults, an instantaneous switch over occurs of the bearer traffic of the bearer payload processors (50-N) from the working line terminal equipment (30) to the protection line terminal equipment (35).

Abstract:
A method for dormant data session reactivation may include a packet control function (118) in a radio access network (104) receiving a first data packet (150) having a source IP address (152), where the first data packet has a destination IP address (152) addressed to reactivate a dormant mobile station (102) coupled to the radio access network. The packet control function may receive a plurality of subsequent data packets (160) having the source IP address, where each of the plurality of subsequent data packets has a subsequent destination IP address (162, 164, 166) and a corresponding time stamp (163, 165, 167). For each of the subsequent destination IP addresses that are substantially sequential, evaluating an absolute value of a slope (270) of the difference between the subsequent destination IP addresses that are substantially sequential over a difference in the corresponding time stamps. If the absolute value of the slope is less than a threshold function (280), denying the first data packet and preventing reactivation of the dormant mobile station by the first data packet.
Abstract:
A method for controlling reverse link loading in a communication system (100) comprises determining a reverse link load in the communication system. The communication system comprises a plurality of mobile units (102, 103) configured to receive a rate indicator from a base station (104). The rate indicator comprises a first state indicating the mobile units can increase their data transmission rate and a second state indicating that the plurality of mobile units can decrease their transmission rate. A duty cycle of the rate indicator is set based on the reverse link load. The relationship between the reverse link loading and the duty cycle of the rate indicator further may be determined adaptively based on the measured loading and link loss rate characteristics. Then, the rate indicator is sent to the plurality of mobile units using the duty cycle.
Abstract:
A data queue service center and method of operation therefore is provided for routing data packets of different Classes of Service over a transmission path. A queue is established for each different Class of Service (12, 14, 16, 18, 20) to be transmitted with a Class Based Weighted Fair Queueing weighting factor for each Class of Service (40). A desired queue residence time for each Class of Service is preallocated based on the level of quality of service required. The actual residence time of packets for each Class of Service is determined (44) and compared with the preallocated residence time for each Class of Service. The CBWFQ weight for each Class of Service is dynamically adjusted (54) based on a comparision of the actual residence time to the preallocated residence time.
