Patent number: 9510170Abstract: A method of performing a compression operation on data in a mobile communication network. An intermediate node located between a mobile terminal and a mobility anchor point node, receives a data payload. If the intermediate node has access to compression information required to perform the compression operation, it performs the compression operation to generate a modified data payload and sends the modified data payload to a next node. If the intermediate node does not have access to compression information required to perform the compression operation, it sends the data payload to the next node. The compression operation may be data compression or de-compression.Type: GrantFiled: June 12, 2013Date of Patent: November 29, 2016Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Fredrik Persson, Hans Eriksson, Jens Knutsson, Paul Stjernholm, Lars Westberg

Patent number: 9456380Abstract: A method and apparatus for handling data compression in a mobile communication network. A node located between a mobile terminal and a mobility anchor point determines compression information relating to data transferred between the node and the mobile terminal. The node then sends the compression information to a network repository node for storage and retrieval by a further node in an event that subsequent mobility of the mobile terminal leads to transferring data between the mobile terminal and the further node.Type: GrantFiled: June 13, 2013Date of Patent: September 27, 2016Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Paul Stjernholm, Hans Eriksson, Jens Knutsson, Fredrik Persson, Lars Westberg

Patent number: 9432050Abstract: A method of updating data compression software. The method comprises using real-time data to train upgraded compression/decompression software. A compressor and/or decompressor function processes and delivers the real-time data using an existing compression/decompression software. Following completion of the training process, the compressor and/or decompressor deactivates the existing compression/decompression software and activates the upgraded compression/decompression software to process and deliver the real-time data.Type: GrantFiled: June 3, 2013Date of Patent: August 30, 2016Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Fredrik Persson, Jens Knutsson, Hans Eriksson, Paul Stjernholm, Lars Westberg

Publication number: 20150172421Abstract: A method and apparatus for data compression in a mobile communication network. A node performing data compression on a downlink towards a mobile terminal compresses data based on an identity of a decompression node. A determination is made that the mobile terminal is no longer receiving data from the decompression node owing to mobility the mobile terminal. An identity of a further decompression node from which the mobile terminal receives data is determined, and data is compressed based on the identity of the further decompression node. The node performing compression can therefore dynamically adapt to mobility of the terminal, potentially resulting in a shorter learning phase.Type: ApplicationFiled: June 13, 2013Publication date: June 18, 2015Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Paul Stjernholm, Hans Eriksson, Jens Knutsson, Fredrik Persson, Lars Westberg

Publication number: 20150156653Abstract: A method of handling user plane data in a packet switched network. A packet inspection node determines a compression ratio and/or content information for the user plane data, and sends said compression ratio and/or content information towards a user plane data handling node. The user plane data handling node receives the compression ratio and/or content information, and handles the user plane data in dependence upon the compression ratio and/or content information.Type: ApplicationFiled: June 11, 2013Publication date: June 4, 2015Inventors: Fredrik Persson, Hans Eriksson, Jens Knutsson, Paul Stjernholm, Lars Westberg

Patent number: 6381458Abstract: A radiocommunication system balances interference reduced by soft handoff with access network loading increased by soft handoff. When the access network loading exceeds some threshold for a particular transmission source, then the system limits or reduces that source's soft handoff connections with remote stations.Type: GrantFiled: May 15, 1998Date of Patent: April 30, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Magnus Frodigh, Jens Knutsson, Magnus Madfors, Magnus Persson

Patent number: 6144861Abstract: The transmit power of a base station transmission to a mobile station is advantageously controlled. The base station receives a signal from the mobile station and determines a signal-to-interference ratio (SIR) associated with the received signal. The base station controls its transmit power to the mobile station using the determined SIR value in conjunction with a transmit power control command received from the mobile station. When the mobile station is in the process of a soft handover involving two or more base stations, each of those base stations determines an SIR value associated with a signal received from the mobile station. Moreover, each of the base stations controls its respective power using both the power control command received from the mobile station and the SIR determined by that base station.Type: GrantFiled: April 7, 1998Date of Patent: November 7, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Magnus Sundelin, Jens Knutsson, Paul Peter Butovitsch, Carl M.

Patent number: 6128506Abstract: A method of stabilizing a communication system having base stations and mobile stations using integrated control of both signal transmission power levels and signal congestion levels. In particular, the method includes measuring a quality such as a signal to interference ratio of a signal transmitted from a mobile station to a base station and measuring a total received signal power at the base station. The signal transmission power of the mobile station is changed based on comparisons of the measured signals with predetermined threshold values. When the measured total received signal power at the base station exceeds the corresponding predetermined threshold value, a congestion control algorithm is executed to reduce the signal congestion level.Type: GrantFiled: September 24, 1997Date of Patent: October 3, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Jens Knutsson, Magnus Persson

Patent number: 6085108Abstract: The power levels of signals transmitted by base stations in a communication are controlled. Power level control commands are transmitted from a remote station to base stations from which the remote station receives signals to control the power levels of the signals transmitted by the base stations. A determination is made whether the remote station simultaneously receives a first signal from a first base station and at least one second signal from at least one second base station that include substantially identical message information. The first and second base stations transmit first and second reports of power levels of the first and second signals, respectively, to the controller. The controller compares the first and second reports and transmits first and second commands for adjusting the power levels of the first and second signals to the first and second base stations, respectively.Type: GrantFiled: April 9, 1998Date of Patent: July 4, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Jens Knutsson, Magnus Persson
