Title: Method and apparatus for reducing co-channel interference
Inventor: REINHOLD STANLEY LYNN
IPC: H04W16/02
Filed: 1997-03-28
Granted: 2005-02-08
Abstract: The amount of co-channel interference which occurs for any given time slot in a cellular communication system can be reduced by distributing or averaging out the co-channel interference to other time slots. This averaging out results from the staggering of control and traffic signals for a given time slot wherein the staggering is relative to the same time slot in the same frequency channel at neighboring clusters of cells. If a transmitter is on a satellite which transmits to the various clusters, the method and apparatus prevents an interfering signal from interfering with the entire time slot. The inventive method and apparatus requires synchronization of the control and traffic signal transmission to the clusters relative to each other so that the amount of delay introduced while staggering the time slots can be predicted and controlled.

Title: Prioritization of data to be transmitted in a router
Inventor: HUUSKO SAMI
IPC: H04L47/2491
Filed: 1997-03-24
Granted: 2007-05-22
Abstract: General Packet Radio Service GPRS is a new service designed for digital mobile systems. Because of bottlenecks, such as an air interface (Um), queues may be formed in routers (SGSN, GGSN, 13, BTS, BSC). Long transmissions of data may slow the operation of interactive applications so that it is no longer sensible to use the applications. In the routers (SGSN, GGSN, 13, BTS, BSC) of the invention, separate queues are formed for each service, quality of service, connection, subscriber and/or application/application class. The quality of service can be indicated by providing each packet with an identity indicating the quality, or a change in the quality can be signalled as separate messages.  In a preferred embodiment of the invention, the amount of data sent from a queue at one go is controlled primarily on the basis of the quality of service of the subscriber. When packets are sent from a queue, it is monitored whether only a small number of packets remains in the queue, and if so, these packets are sent as well.

Granted: 2009-11-17
Abstract: A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line fax machines are described. To process a fax, a source interface (24a) waits until an interface to a destination fax machine (18b) has been established before establishing an interface to a source fax machine (18a). The source fax transmission rate must be less than or equal to the destination fax transmission rate and the data rate of the digital channel. To establish the source fax interface at the proper rate, the source interface (24a) first selects an initial data rate from a set of standard fax transmission rates. The source interface (24a) sends unacceptable rate (failure to train) messages to the source fax machine (18a) until the source fax transmission rate is less than or equal to the data channel rate and the destination fax transmission rate. During fax processing, the destination interface (24b) inserts non-printing data (fill bits) if the destination fax transmission rate is greater than the source fax transmission rate. Fill bits are also inserted to compensate for transmission delays.

Abstract: A signal processor for effecting the conversion of an audio data signal from one format to another. The signal processor has a signal converter that can selectively acquire two operative modes, namely a first operative mode and a second operative mode. In the first operative mode, the signal converter transforms the audio data signal from one format to another and releases the converted audio data signal from the output of the signal processor. In the second operative mode, the signal converter is disabled and permits passage of the audio data signal to the output without conversion. The signal processor has a control unit for controlling the transition of the signal converter between operative modes. The control unit enables the signal converter to pass from the first operative mode to the second operative mode when at least one operative condition has been satisfied. The control unit reacts to a link impairment occurring on the data communication channel to alter the operative condition to be satisfied to enable passage from the first operative mode to the second operative mode. In a specific example of implementation, the modification to the operative condition can be such as to "tighten" the requirements to be met for switching from the first to the second operative mode.
