摘要： A method and apparatus for distributing and consolidating data packets onto multiple network interfaces includes using frame-based inverse multiplexing to parse high-speed data into frames for placement onto lower-speed E1 or T1 connections between a base station controller and a base station, or between two base station controllers, in a cellular telephony network. The inverse multiplexing algorithm may be implemented with hardware such as, e.g., FIFOs and registers. The frames are transmitted across the E1 or T1 connections and then received, buffered, and multiplexed into a single high-speed data stream.

摘要： A loopback processing method includes detecting a loopback at a first entity in a wide area network. The detection is accomplished by recognizing that a “memorized” frame has returned on the same communications interface within a given period of time. The time interval between sending the frame and detecting it returning at the same port may be recorded and sent to an operator to provide information on the relative location of the loopback in the network. A loopback detect sequence is sent from the first entity to a second entity on the communications interface in loopback. Because of the loopback, both entities receive the loopback detect sequence. Either or both entities may inform a network operator of the loopback. The first entity has stopped using the link in loopback for real data, instead sending the loopback detect sequence. The second entity, upon detecting the loopback detect sequence, also stops using the link for real data. When the first entity stops detecting the loopback detect sequence returning on the link, the first entity stops sending the loopback detect sequence and begins using the link for real data again. When the second entity stops receiving the loopback detect sequence on the link, the second entity begins using the link for real data again. Either or both entities may inform a network operator that the loopback is gone.

摘要： A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system. The link load message include peak queue length and average frame rate information.

摘要： A base station can communicate resource allocation to a wireless mobile station in an uplink map information element. The base station can identify destination mobile stations using a shorthand connection identifier. The base station parses the connection identifier field into a shorthand connection identifier field and an embedded subfield data field. The shorthand connection identifier field can be sized to support a predetermined number of mobile stations. The base station can further parse the embedded subfield field into a number of sub-fields, each communicating a different set of control information. In one embodiment, the base station utilizes the embedded subfield to communicate power, timing, and frequency information to the destination mobile station.

摘要： A method for producing an analog output from a digital input is described. A digital pulse train is received having an average value which is proportional to a digital conversion value. The digital pulse train is driven at a periodic interval to produce a modulated tristate-gate output. The modulated tristate-gate output is averaged to produce an analog output. Optionally, the pulse train is also driven at an additional periodic interval having a duty cycle of more, or less, than less than 50%. The pulse train may also be driven steadily.

摘要： Methods and apparatus for reducing out of band emissions through selective resource allocation, transmit power control, or a combination thereof. A resource controller, such as a base station, can allocate uplink resources to a requesting subscriber station based in part on an expected transmit power. The base station can allocate uplink bandwidth to the subscriber station based on an expected subscriber station uplink transmit power and a frequency of a restricted emissions band. Those subscriber stations having higher expected transmit powers are allocated bandwidth further from the restricted emissions band. The subscriber station can perform complementary transmit power control based on allocated uplink resources. The subscriber station can limit a transmit power based in part on a bandwidth allocation, modulation type allocation, or some combination thereof.

摘要： An electrical current (“EC”) manager module may assign a plurality of hardware elements of the PCD to one of two groups. The EC manager module may monitor individual electrical current levels of one of the groups as well as calculate an instantaneous electrical current level for the PCD based on a current charge status for the PCD. The EC manager module may then adjust operation of at least one hardware element to keep operation of the PCD below the calculated instantaneous electrical current level for the PCD. The EC manager module may estimate an electrical current level for one of the groups based on requests issued to hardware elements. The EC manager module may also compare the calculated instantaneous electrical current level to the monitored electrical current level. The calculated instantaneous electrical current level may be compared to minimum current levels listed in a table.

摘要： Automatic gain control (AGC) methods and apparatus that implement a dynamically variable AGC setpoint. The variable AGC setpoint can be determined based in part on the type of modulation used to convey information to the receiver. The AGC setpoint can be set higher than a nominal setpoint for higher order modulation types and can be lower than the nominal setpoint for low order modulation types. The manner in which gain is adjusted can also depend on the modulation type. The gains can be increased according to a front to back priority. The gains can be decreased in a priority that is based on the modulation type. For lower order modulation types, the gain controller can decrease gain according to a back to front priority. For higher order modulation types, the gain controller can maintain linearity of front end amplifiers prior to decreasing gain according to a back to front priority.
