摘要： A base station controller system comprises a high data rate distributed switching fabric providing flexible access to call processing resource pools. The arrangement permits a system controller to selectively assign specific resources depending on call type based on configuring the distributed switching fabric. The transport links comprising the distributed switching fabric provide redundant access to each of the resource pools, greatly reducing the portion of overall call processing capability lost with a single failure. Preferably, the distributed switching fabric comprises a central ATM switch and a number of distributed ATM switches interconnecting the resource pools to the central switching resource. The system may adopt a rack arrangement wherein a processing subrack includes the mix of different processing resources necessary to support substantially all call flow processing for one or more types of calls. The system's call capacity is thus easily scalable based on adding additional processing subracks.

摘要： A Base Station Controller (BSC) that reduces the occurrence of audible noise in a Code Division Multiple Access (CDMA) radio network is provided. The BSC according to one embodiment of the present invention comprises a Media Stream Board (MSB) for compressing groups of 160 PCM speech samples from a Public Switch Telephone Network (PSTN) into vocoded frames, and a Special Purpose Board (SPB) for reformatting the vocoded frames from the MSB into over-the-air CDMA vocoded frames. The MSB and SPB each have a local timer that is slave to “PSTN time”. The BSC further comprises a Timing Unit Board (TUB) connected to a GPS receiver. The TUB receives “GPS time” from the GPS receiver. The TUB generates timing cells, each containing time-of-day information according to “GPS time”. The TUB distributes the timing cells to the MSB and the SPB over an Asynchronous Transfer Mode (ATM) network. The MSB and SPB use the received timing cells to compare their local timer, which tracks “PSTN time”, to “GPS time”. The MSB and the SPB realign their local timer with “GPS time” whenever their local timer drifts from “GPS time” outside of a predetermined time window.

摘要： A timing network for a wireless communication network includes first and second Timing Unit Board (TUB) and processor boards for processing speech channels of the radio network, each processor board having a local timer that is slave to “PSTN time” from a Public Switch Telephone Network (PSTN). The first and second TUB each alternately transmits a timing cell containing time information to each processor board over a transport network. Each processor board realigns its local timer with the time information contained in a received timing cell whenever its local timer drifts from the time information contained in the received timing cell by a predetermined time offset. When one of the TUBs fails to transmit timing cells to the processor boards or transmits timing cells containing erroneous time information, the processor boards rely on the remaining TUB for timing cells to realign their local timers.

摘要： Systems, methods, and other embodiments associated with real-time text indexing are described. One example method includes receiving a document for indexing in a search system that includes a mature index and indexing the received document in a staging index. The staging index may be stored in direct access memory associated with query processing that does not degrade query performance even when postings become fragmented. The staging index and the mature text index are accessed to process queries on the search system. The example method may also include periodically merging the staging index into the mature index based on query feedback.
