摘要： The present invention relates to an architectural model of a radio network unit, e.g. a Radio Base Station, that separates functionality in such a way that it is possible to easily adapt the unit to various requirements and conditions. The radio network unit comprises an internal RBS-interface that subdivides the its functionality into a first part, which solely relates to the functionality of the radio network, and a second part, which solely relates to the radio part, i.e. the airborne part of the transmission. The internal interface comprises at least a link that handles the necessary additional communication that arises due to the subdivision and a link that handles the user data that is to be processed, i.e. transmitted or received, by said unit.

摘要： A method and apparatus in a radio telecommunications system for converting data from a first sample rate to a second sample rate such that the first and second sample rates are preferably within 10% of each other are disclosed. An input buffer receives a plurality of data groupings at a first sample rate. A spline filter utilizes the input data along with a phase difference between input and output data to calculate a third order spline function and an output time for the input data. This information is used to convert the input data at the first sample rate to output data at a second sample rate. The output data is buffered within an output buffer until transmitted to an associated base band unit.

摘要： A telecommunications system and method is disclosed for reducing the signaling load on the network by instructing a Location Measurement Unit (LMU) to measure the relation between the absolute time and air interface timing, e.g., TDMA frame number, only when a positioning request has been received. Prior to configuring the LMU for time of arrival (TOA)-based positioning of a particular mobile station, the Serving Mobile Location Center (SMLC) can request an LMU associated with a particular cell to perform an asynchronous handover within the same cell. During this asynchronous handover, the LMU measures the relation between the absolute time and the TDMA frame number, and sends this relation information to the SMLC. The SMLC uses this relation information in configuring the LMU for TOA-based positioning of the particular mobile station.

摘要： A method for combining signals being conveyed across a digital interface is disclosed. In one embodiment, a subharmonic of a frequency is superimposed on asynchronous data. The subharmonic can be used to carry a frequency reference across the digital interface. In another embodiment, a time stamp algorithm is used to carry a time reference from a master circuit to a slave circuit across a digital interface. The transmission delay between the master circuit and slave circuit is measured. The master circuit transmits time correction messages to the slave circuit, based on the time the correction message is transmitted plus the transmission delay. In another embodiment, a reset signal is carried across a digital interface by discontinuing the transfer of a frequency reference for a predetermined time. A lowpass filter can be used at the receiving side of the interface to recognize the absence of the frequency reference and initiate a reset procedure at that side.

摘要： Each transmitter/receiver pair of a radio base station is connected via an antenna bus and radio frequency feeder to antenna near parts equipment such as active antennas, boosters and tower mounted amplifiers. Automatic configuration and calibration of the antenna near parts equipment is accomplished by establishing communication between the base station and each of its connected antenna near part components. Each antenna near part component sends its identification to the base station over the antenna bus at power-on. Furthermore, communications selectively sent over the radio frequency feeder are monitored to determine the connectivity between individual transmitter/receiver pairs of the base station and each antenna near parts equipment. These radio frequency feeder communications are further processed to determine calibration data for configuring each antenna near parts equipment for optimal operation.
