摘要： A method and system for selecting traffic processors for processing and transmitting broadcast/multicast service flow in a cellular network includes evaluating processor occupancy of a plurality of traffic processors and selecting the traffic processors with the highest available processor occupancy. The cellular network has one or more base stations that are connected to a radio network controller, the radio network controller having a plurality of traffic processors to process the radio signals and data traffic to be transmitted to the base stations. A required processor occupancy for transmitting the broadcast/multicast service flow to the base stations is estimated and the traffic processors are selected such that their combined available processor occupancy is greater than the required processor occupancy for the broadcast/multicast service flow. The method and system optimizes resource utilization and distribution among the plurality of traffic processors.

摘要： A method for adjusting the power of a probe signal to be transmitted by user equipment to system equipment of a wireless communication system. The power of the probe signal is adjusted based on information received by the user equipment from the system equipment. The information is a local mean of RSSI at the system equipment. The adjusted probe signal is transmitted and thus has an increased likelihood of being detected by the system equipment. Also, the power available for transmitting the probe signal is used more efficiently when the probe signal is adjusted in accordance with the local mean information received by the user equipment from system equipment of the wireless communication system.

摘要： In a method to support geo-location emergency services in a wireless network, a request message is transmitted from a source base station of one vendor to a target base station of another vendor. For example, the request message might be sent subsequent to a wireless unit initiating an emergency services communication, where it is desired to determine the location of the wireless unit by radiolocation, or otherwise at the network level. Upon receiving the request message, the target base station transmits a report message to the source base station, which includes a one-way transmission delay (or other propagation delay information) of the wireless unit as measured at the target base station. Communication protocols in the network are configured so that there are no automatic transmissions of propagation delay information. Instead, base stations transmit propagation delay information only upon the receipt of request messages requesting the information.

摘要： In a method for processor overload control in a wireless or other network, a processor occupancy level (“PO”) of a network processing unit is monitored and compared to a target PO. If the measured PO exceeds the target PO, one or more network load sources are controlled to reduce the data load of the processing unit, until the measured PO falls below a designated PO. “Load source” refers to a source of extant and/or potential data traffic through the processing unit, and/or a network control factor relating thereto, the control of which results in a reduction (or prevents an increase) in the data traffic handled by the processor. Examples include existing data flows, new calls, and BE flow window size. The load sources are controlled according to differentiated QOS levels, wherein non delay-critical data flows (e.g., BE flows) are reduced before delay-critical data flows, e.g., EF or AF flows.

摘要： In a method and system for controlling base station processing unit overload and buffer overflow in a unified manner, one or more processing units of the base station are monitored to determine if the processing unit(s) has entered an overload condition. If so, on a per flow basis, the system generates an advertise window for controlling the amount of data in the data flow, as transmitted to the processing unit from an upstream entity. The advertise window is generated taking into consideration both processor overload and buffer overflow factors. By incorporating these factors, the advertise windows collectively serve to limit both processor overload and buffer overflow, on a system wide basis.
