Abstract: PROBLEM TO BE SOLVED: To provide a method and a communication node to control a data flow provided to a communication node for serving a wireless communication system. SOLUTION: A communication node captures an incoming message to its buffer memory if the incoming message is contained within a range of a storage capacity with respect to a class of the incoming message and no congestion takes place in the buffer memory. A state detector detects whether or not congestion takes place in the buffer memory by evaluating an occupancy ratio of the buffer memory. The range of the storage capacity is decided by obtaining an operating rate of the buffer memory depending on the specific class of a data message specified according to an economical value rating estimated by the data message.

Abstract: PROBLEM TO BE SOLVED: To provide a data flow performance enhance means in a communication node. SOLUTION: The communication node 14 predicts a transmission/departure time of a received data message from an output section 16 just after the reception of the received data message in an input section 12 of the communication node 14. The communication node 14 decides whether or not the received data message is resident in the communication node for a latent time longer than a wait time limit based on the predicted transmission departure time. If the received data message is transmitted before the wait time limit expires, the communication node 14 accepts the received data message for the storage to a buffer memory 36 for the purpose of expected transmission from the output section 16.

Abstract: PROBLEM TO BE SOLVED: To allow base stations to attain synchronization between base stations, without mounting an expensive external device in TDMA and AMPS systems. SOLUTION: An object base station records the time stamp of a signal arrived from a service base station. Each object base station records the time stamp with respect to a clock signal of each of them. Each object base station is operated synchronously with the service base station, on the basis of a downlink offset calculated by each object base station. The downlink offset indicates a fractional symbol time from the time, the service base station sends the signal to a prescribed periodic time succeeding a symbol clock of the concerned object base station with respect to the internal symbol clock of each object base station. Each object base station decides the time, when the signal is transmitted on the basis of both the time, when the concerned object base station receives the signal and a known time required for propagation of the signal from the service base station to the object base station.

Abstract: A communications node predicts a transmission-departure time of a receive data message from an output upon reception of the receive data message at an input of the communications node. The communications node determines if the receive data message would remain stored within the communications node for a latent duration longer than a waiting-time limit based on the predicted transmission-departure time. The communications node admits the receive data message, for storage in a buffer memory of the communications node for prospective transmission over the output, if the receive data message would be transmitted prior to expiration of the waiting-time limit.

Abstract: The synchronization system uses a TDMA or AMPS air interface to provide tuning synchronization between previously unsynchronized base stations. The synchronization of base stations is critical between when determining the geographical position of a mobile because the geographical position is determined using a time difference of arrival method. In order to synchronize a remote base station with a serving base station, the remote base station receives a signal from the serving base station and measuring the receiving time of the signal at the remote base station in relation to the clock of the remote base station. The synchronization system determines the transmission time of the signal based on the reception time of the signal and the distance between the base stations, in relation to the clock signal of the second station, and synchronizes the clock of the remote base station to the clock of the serving base station based on the offset in the clock cycles at the time the signal was transmitted.

Abstract: A communications node admits the receive data message to the buffer memory if the receive arriving message falls within the capacity rang e of a class of the receive data messages and if the buffer memory is not congested. A state detector detects if the buffer memory is congested by evaluating the occupancy rate of the buffer memory, or otherwise. The capacity range determines the utilization of buffer memory by a particular class of data messages, which may be defined in accordance with an estimated economic value rating of the data messages.

Abstract: The synchronization system uses a TDMA or AMPS air interface to provide timing synchronization between previously unsynchronized base stations. The synchronization of base stations is critical between when determining the geographical position of a mobile because the geographical position is determined using a time difference of arrival method. In order to synchronize a remote base station with a serving base station, the remote base station receives a signal from the serving base station and measuring the receiving time of the signal at the remote base station in relation to the clock of the remote base station. The synchronization system determines the transmission time of the signal based on the reception time of the signa l and the distance between the base stations, in relation to the clock signal of the second station, and synchronizes the clock of the remote base station to the clock of the serving base station based on the offset in the clock cycles at the time the signal was transmitted.
