摘要： Disclosed is a method of controlling communication rates over a link within a communications system. The method includes storing packets associated with voice and data traffic in individual buffers, and determining an instantaneous number of active voice and active data traffic in the individual buffers. Furthermore, a total link bandwidth that the active voice traffic will consume during a frame interval is determined, and an available link bandwidth, for the active data traffic, remaining after the total link bandwidth is calculated. Finally, rate control is applied to fit the active data traffic in the available link bandwidth. Rate control is achieved by allowing a data session to send data at a portion of its full-rate, where the portion is determined as a function of the instantaneous load generated by all sessions carried on the link.

摘要： A back haul architecture effectively reduces the reactivation times for both forward-link and reverse-link data transmissions over CDMA wireless communications systems, by relying on packet-mode transmissions over the back haul between a frame selection/distribution (FSD) function and the appropriate base stations. In particular, for the forward direction, the FSD function transmits forward-link data only to one base station, which is solely responsible for controlling the forward-link air interface with the corresponding mobile unit. For the reverse direction, each base station that receives frames of reverse-link data from the mobile unit, assigns a time tag to the frame, divides the frame into one or more data packets, assigns a different sequence number to each data packet, and transmits the data packets to the FSD function over the back haul, all without first synchronizing time with any other base station that is also operating in reverse-link soft hand-off with that mobile unit.

摘要： In a wireless communications system having a centralized interworking function (IWF) and geographically distributed base stations, a packet-oriented frame selection/distribution (FSD) function forwards forward-link user data intended for a particular mobile unit directly to a primary base station, which determines whether to transmit the forward user data to the mobile unit using a fundamental channel or a supplemental channel. If the data is to be transmitted using a fundamental channel, when the base station is operating in soft handoff, the forward user data is transmitted from the primary base station back to a circuit-oriented FSD function for forwarding to all of the base stations currently participating in the soft handoff, so that all of the base stations can transmit the forward-link user data to the mobile unit at the same time. If the data is to be transmitted using a supplemental channel, then the primary base station is able to assign a supplemental channel and transmit the forward user data to the mobile unit using the supplemental channel in simplex mode, independent of whether or not the mobile unit is otherwise operating in soft handoff. In this way, forward-link data transmissions can be performed without first having to coordinate either the timing or the data rate with any other base stations or with the FSD function. As such, the reactivation time needed to resume active forward-link data transmissions using a supplemental channel from the control hold state is less than the corresponding reactivation time under the prior art, which does require coordination of timing and data rate between all base stations in soft handoff.

摘要： A reconfigurable base station suitable for supporting multiple wireless communication system standards includes a set of channel unit boards, each providing processing operations for user signals assigned to multiple carriers of the system, a set of a radio boards, each generating a radio frequency (RF) output signal for each of at least a subset of the multiple carriers, and a reconfigurable bus interconnecting the channel unit boards and radio boards. The base stations configured to support a particular wireless system standard, such as IS-95 CDMA, by assigning particular user signals to designated signal lines of the reconfigurable bus. The base station may then be reconfigured to support other CDMA standards, such as, e.g., IS-95C with or without Orthogonal to Transmit Diversity (QTD), Multi-Carrier (MC) cdma2009, or Universal Mobile Telecommunications System, (UMTS) by assigning. other user signals to the signal lines of the reconfigurable bus. The assignment of signal lines may be implemented dynamically under the control of software running on a base station control computer, or by establishing fixed connections between the bus signal lines and appropriate ports of the channel unit and radio boards.

摘要： A method and apparatus are disclosed for automatically determining system configuration information, including the sector, carrier frequency and bus assignment of each hardware component installed on equipment, such as a cell station. In an illustrative cell station implementation, each cell station includes a hardware controller that communicates on a common bus with a plurality of hardware components. When each cell station is powered up or reset, each hardware component reads an identification value (or a portion thereof) that has some physical significance from a backplane on which the hardware component is installed. The identification information obtained from the backplane is used to derive a bus address that uniquely identifies each hardware component on the common bus. In addition, the identification information contains information that describes the hardware component and how the component is located within the cell station. In the illustrative embodiment, the identification value identifies the carrier frequency, frame, sector number (such as &agr;, &bgr;, &ggr;), unit type and unit number associated with the hardware component. The hardware component can provide information to the hardware controller that allows the hardware controller to generate a map of the hardware components located within the cell and determine their interconnection.

摘要： A method and apparatus for isolating portions of multi-tasking software for integration testing (debugging) are disclosed. One or more applications software tasks can advantageously be isolated for testing from other "remote" tasks in the same subsystem or other subsystems, or one or more complete computer subsystems having multi-tasking software can be isolated from other "remote" subsystems having other multi-tasking software. Such isolation facilitates debugging without having to modify the application software. In accordance with illustrated embodiments of the invention, tasks or complete subsystems are isolated using a test task and an external user. The test task is operable to alter communications pathways for the transfer of messages between tasks that are supported by a common communications mechanism that is resident in multi-tasking computer systems. The external user is operable to emulate the functions of the remote software tasks. A message from a task being tested that is intended for a remote task in the same or a different subsystem is rerouted to the test task and then to the external user. The external user emulates the functions of the remote task, generates a response message, and delivers the response message, via the test task, to an appropriate task under test. Thus, without any modification to the software tasks, such tasks can be debugged for integration with other tasks in the system. As such, the final production software is identical to the debugged software.

摘要： A mechanized system distributing the access, test and communication functions to the point of testing, typically the centralized switching facility serving the telephone loops and equipment to be tested. Computer (200) stores information about each subscriber loop in the geographical area served by a system. Front-end computers (220,221) interact with computer (200) to retrieve pertinent data regarding loops to be tested. Each switching facility in an area includes a loop testing system (e.g., 160) that implements the required functions. The communication functions residing in front-end computers (220,221) and loop testing systems (160,161) are coupled via a data communication network (140) in a manner that allows any front-end computer to communicate with any loop testing system. Users of the system control access and test from consoles having the capability of establishing independent communication paths over the national dial network for interactive tests on loops accessed through standard test trunks. Microprocessor-based circuitry is utilized for numerous system tasks such as signal generation, digital signal processing and controlling sensitive analog measurements. Signal generation includes digital generation of analog waveforms. Signal processing techniques incorporate various digital filters to analyze sample sequences derived from, for example, dial pulses and coin telephone signals. Sensitive analog measurements of loop characteristics are effected with a magnetic current detector that operates over broad current and frequency ranges. Frequency dependent measurements are converted to DC using synchronous demodulation techniques to enhance resolution.
