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.

The present invention is an apparatus and a method for sharing a communication channel among two or more base stations connected to a base station controller via a common transmission line in a channelized format. The present invention allows each of the base stations to receive data transmitted over a shared communication channel from the base station controller, to determine whether the data transmitted from the base station controller is intended for that base station, and to insert its data into the communication channel without interfering with data transmitted by other base stations over the communication channel. In one embodiment, each of the base stations is configured to bridge onto the transmission facility such that signaling messages being transmitted over a signaling channel may be received by all of the base stations. The signaling messages has associated identifiers for specifying particular base stations to which the signaling messages are intended. In another embodiment, each of the base stations can insert its signaling message into the data stream over the signaling channel without interfering with signaling messages already in the data stream.

The present invention provides a method for implementation in a wireless communication system including a plurality of base stations, a plurality of gateways, and a plurality of mobility management entities. The method includes receiving, at a first mobility management entity and from a first base station, measurement data collected by the first base station for a first mobile unit having a connection to the wireless communication system via the first base station. The measurement data includes a temporary identifier associated with the first mobile unit for the duration of the connection. The method also includes identifying the first mobile unit using the temporary identifier and forming a first record associated with the first mobile unit. The first record includes the measurement data collected by the first base station for the first mobile unit and previously collected measurement data for the first mobile unit.

摘要:
The system and method of the invention enable any channel of a multi-channel communication link to be used for transmission of a control signal to a system component by a system controller. The system component, connected to the system controller by the multi-channel communication link, automatically locates the one or more signaling channels carrying the control signal(s) and then establishes communication with the system controller in accordance with the control signal(s). If no signaling channels are located after a predetermined number of attempts or after a predetermined period of time, the system component may, if particular conditions are met, reset itself before continuing to search for the signaling channel(s).

摘要:
A communications system that is arranged to transport so-called connection oriented messages via respective virtual circuit connections is enhanced so that it also transports so-called connectionless messages via a predefined virtual circuit connection that is common among those data modules which participate in the connectionless message service. In particular, each module which participates in the connectionless message service is assigned, in addition to a primary address that is used in conjunction with associated channels numbers to transport respective connection oriented messages, a common address and a channel number that is used solely for transporting connectionless messages. In this way, the communications system processes connectionless messages as though they were connection oriented messages.

A mechanized system distributing the access, test and communication functions to the pont 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 in 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.
