A technique for reporting faults of a base station in a digital cellular system, includes: a base station management unit having a table storing information of predetermined faults; and a base station including multiple devices, which detects the faults of the devices and reports addresses for accessing relevant fault messages of the table to the base station management unit.
A method for automating a test of a base transceiver station in a mobile telecommunication system is disclosed. In a base station manager (BSM) for managing a plurality of base transceiver stations providing communication service to mobile stations that move within a service coverage area, the method comprises the steps of checking whether an operator is registered, receiving parameters for command of test items, and selecting commands of test items to test base transceiver stations. When parameters are not inputted, a default parameter is read, but when parameters are inputted, the inputted parameters are saved as new default. Not only the selected test items, but also all test items under the selected test items are automatically executed at a time. The results of testing is stored and outputted in accordance with identification of systems selected by an operator.
A method and system for detecting failures in a wireless communications network. A computer is programmed to remotely access a platform, such as a network switch or database, that stores data indicative of the performance of the wireless communications network infrastructure. The computer downloads the data, parses the data to extract wireless communications network events such as dropped calls, noise or lack of audio, sorts the events, and passes the events through an event-to-failure mapping module to identify probable network component failures. Data is preferably analyzed over periods of less than 24 hours. The probable failures are preferably reported to network operations personnel who can then resolve the failures on a more timely basis.
A Transmit Diversity Redundancy controller dynamically mediates implementation of diversity and antenna hopping by detecting and remediating faults on antenna branches while minimizing the capital investment required. The controller monitors the equipment along the antenna branches. If a fault occurs, the controller determines the appropriate fault remediation measures to implement based on default settings, or relays an indicator to an external processor (e.g., a BTS or BSC CPU) and awaits instructions. If traffic on the BTS is high, the external processor instructs the TDR controller to combine the signals carried by the downed branch with the signals carried by the active branches, and the combined carrier signals are transmitted over the active branches. Otherwise, the external processor instructs the controller to allow signals carried by the downed antenna branch to be dropped, and notifies the BSC to suspend assignment of calls to the dropped carriers until the branch is restored.
A portable subscriber unit (122) provides (402) communications for a user, and monitors (404) a parameter indicative of communication quality during the communications. The portable subscriber unit compares (406) the parameter with a predetermined threshold; and when the communication quality deteriorates (408) such that the parameter reaches the predetermined threshold, the portable subscriber unit determines (412) geographic coordinates corresponding to the location at which the communication difficulty occurred, and adds (414) a communication difficulty report identifying the parameter and the geographic coordinates to a record of communication difficulty reports stored in the portable subscriber unit. When the portable subscriber unit receives (502) a request for the record of communication difficulty reports from a fixed portion (102) of a two-way wireless communication system, the portable subscriber unit communicates (504) the record of communication difficulty reports to the fixed portion.
A method and system are disclosed for implementing management functions on both sides of a base station management interface (i.e., in both the base station manager and the base station) so that a plurality of different types of base stations can be managed by the same base station manager. The management service functions are allocated to the specific base station(s) involved. As such, each type of base station in the network can maintain all of the software needed to perform the base station management services (e.g., element management services). Consequently, one common base station manager can be used for the management of any type of base station. In other words, the base station manager can be considered as a generic base station manager, and any base station can be connected to the generic base station manager via a management interface.
