The present invention relates to a device, system and a method for obtaining and monitoring vehicular parameters and in particular, to such a device, system and method in which vehicular parameters are sniffed and automatically ascertained from a vehicle controller data bus.

Method and system for retrieving vehicular parameters from a vehicle data bus

The amount of data that is transmitted over a cellular network is reduced thereby providing an improvement in the quality of service. The data reduction is obtained by intercepting data units transferred over a bearer between two nodes, such as a BTS and BSC. The current load for a bearer is determined and based on the current load, the source of the data is requested to change the bit rate of subsequent data units. Thus, the bit rate of data that is transmitted toward two intermediate nodes is changed in order to control the load over a bearer that connects the two intermediate nodes.

Method and system for improving quality of service over a fixed network

Bandwidth utilization over bearers in a fixed cellular network is improved by reducing the amount of data required to be transported. At each side of the bearer, data blocks (such as Iub blocks) are received and, prior to transmitting them across the bearer, they are analyzed to determine if they can be modified in such a manner to decrease the amount of data. On the other end of the bearer, received blocks are analyzed to determine if they have been modified, and if so, the blocks are reconstructed to a format that may not be identical to the original format but, that is operationally equivalent from a user perspective. The modifications to the blocks can be based on the type of data being transmitted. For instance, if the data is for a video session or and audio session, the modifications can be different. Information regarding the reconstruction of the blocks can be sent to the other end of the bearer as a part of the data or through other channels.
