Patent number: 8707137Abstract: Communication frames transmitted over a communication network may have different QoS requirements for each communication session. The required BER for different types of communication session is selected based at least in part on the required QoS for that communication session. When frames are received, the QoS level associated with the frame is determined. Based at least in part on the QoS level, the frames are routed toward the destination over a path that provides BER protection commensurate with the required QoS. Prior to transmission to the destination, the processed frames are multiplexed together into a single stream of segment. On the receiving side, the stream of segments is divided in accordance with the QoS level associated with the segments and the segments are routed over a path that is selected, at least in part, on the QoS level. Over this selected path, the original frames are restored and then provided to the destination node.Type: GrantFiled: August 11, 2010Date of Patent: April 22, 2014Assignee: Celtro Ltd.

Patent number: 8370721Abstract: A bandwidth sensing system operates to sense the existence of additional bandwidth available for transmitting data over a best effort communication. The operations include receiving an original block of data from a transmitting node and calculating error correction data based on the original block of data. The original block of data and the error correction data is then transmitted toward a receiving node. The data may be simply appended or, the entire block may be modified during the error correction data process. When the original block of data and error correction data is received at the receiving end associated with the receiving node, the data is analyzed to determine if any errors occurred in the transmission. If so, the error correction data is used to maintain the integrity of the transmitted data by restoring the original block.Type: GrantFiled: November 9, 2009Date of Patent: February 5, 2013Assignee: Celtro LtdInventor: Ram Arye

Patent number: 8284692Abstract: The allocation of network resources, such as bandwidth, etc., can be dynamically adjusted based on the knowledge of the traffic volume, the transport protocol used by the payload and entitled level of services. The type of transport protocol can be determined by monitoring and analyzing characteristics of the data traffic. The frames or packets over a particular channel are monitored to identify the time between frames for a particular period of time. This time then can be used to calculate a recent average time. The timing of subsequently received frames can then be compared to this average to determine if the transport protocol is UDP, TCP or some other protocol. In other embodiments a recent average throughput can be calculated and be compared to a current throughput. This information, along with the load and entitled level of service is used to control the network resources.Type: GrantFiled: July 24, 2008Date of Patent: October 9, 2012Assignee: Celtro LtdInventor: Ram Arye

Patent number: 8219107Abstract: 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.Type: GrantFiled: February 12, 2008Date of Patent: July 10, 2012Assignee: Celtro LtdInventors: Shay Bakfan, Hezi Manos

Patent number: 8194669Abstract: A system and method suitable for identifying the type of communication that is transferred between two intermediate nodes over a communication link that has a plurality of different channels or sub-channels each of which carry user's data. With accurate identification of the communication types, subsequent bandwidth management decisions can be made such that a telecommunications system can have increased bandwidth utilization without jeopardizing user contracted QoS levels.Type: GrantFiled: April 23, 2009Date of Patent: June 5, 2012Assignee: Celtro LtdInventors: Ram Arye, Emanuel Fleishman

Patent number: 8107419Abstract: 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.Type: GrantFiled: February 13, 2008Date of Patent: January 31, 2012Assignee: Celtro LtdInventors: Hezi Manos, Shay Bakfan

Patent number: 8094607Abstract: Multi-channel network communication is improved by reducing the amount of data that is transmitted over connections that can stem from a similar source. Content of data packets transmitted from the source are reduced and the result is compared to previously transmitted data packets. If identical packets are found, then only an identification of the packet is transmitted. At the receiving side, the identification is used to identify a previously received data packet and use that as though it was the recently received packet. If a similar packet is identified, then the identification of the similar packet, along with change information is transmitted to the receiving side.Type: GrantFiled: July 24, 2007Date of Patent: January 10, 2012Assignee: Celtro LtdInventors: Ram Arye, Emanuel Fleishman, Shahar Gorodeisky

Patent number: RE39990Abstract: A method of forwarding signals over a cellular link. The method includes receiving, at a first base station of a cellular fixed network, a packet of signals having a data payload directed to a second base station, determining whether the data payload will be used by the second base station, and forwarding the entire packet if the data payload will be used and not forwarding the entire packet if the data payload will not be used.Type: GrantFiled: August 1, 2005Date of Patent: January 1, 2008Assignee: Celtro Ltd.Inventors: Ofer Shalem, Lior Kushmaro
