Publication number: 20130262950Abstract: The invention discloses a method for use in a cellular system with an RBS which controls traffic to and from a cell, with one User Equipment, UE, in the cell. The RBS and the UE receive and transmit information between each other, one of them being a sending party and the other one is a receiving party, and errors in messages which are received can be detected by the receiving party by a first error detection method and if errors are detected in received messages, the receiving party can request a retransmission from the transmitting party. The receiving party stores the order in which retransmissions are requested, so that erroneous retransmissions may be detected by the receiving party without the first error detection method.Type: ApplicationFiled: May 24, 2013Publication date: October 3, 2013Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Ylva Timner, Håkan Axelsson

Publication number: 20120230219Abstract: The invention relates to a method in a source radio base station (14) for enabling a handover of a connection to a user equipment (13) from a source cell (11) to a target cell (17). The source radio base station (14) serves the source cell (11) and is comprised in a radio communications network (100). The source radio base station receives (802) at least a first segment of a measurement report from the user equipment (13), which measurement report indicates received signal power of signals of neighbouring cells. The source radio base station then determines (803) a transmission time of the segment of the measurement report and compares (804) the transmission time with a predefined time threshold value. When the transmission time has exceeded the time threshold value, the source radio base station determines (806) whether to perform the handover based on the at least first segment of the measurement report.Type: ApplicationFiled: November 25, 2009Publication date: September 13, 2012Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Jonas Pettersson, Kristofer Sandlund, Ylva Timner, Min Wang, Mats Wernersson

Patent number: 8155034Abstract: A method (200) for a cellular system (100), with an RBS (120) which controls a cell (110) with User Equipments UE (130, 140). The RBS and the UEs exchange data which may comprise sequence numbers, and exchange reports on whether or not data has been received successfully, so that both the UE and the RBS can be the reporting party and the report receiving party. The reporting party sends a report (210) to the report receiving party on whether or not data has been received successfully, together with data to the report receiving party or to another party in the cell. The reporting party decides (220) the contents of the report using one of the following priority rules: Data with lower delay tolerance is given priority, Data detected as received in error is given priority, Data is given priority according to block sequence numbers.Type: GrantFiled: March 27, 2007Date of Patent: April 10, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Ylva Timner, Mårten Sundberg, Håkan Persson, Andreas Bergström

Patent number: 8107425Abstract: The present invention provides a quality based resource management in a radio communications system. In this resource management, channel resources are dynamically allocated to a multiresource capable mobile unit based on a radio quality of a radio link between the mobile unit and an associated base station. Thus, the amount of these resources to be allocated to the mobile unit is determined based on this radio quality and can be dynamically updated based on new quality reports. A high experienced quality means that more resources are allocated. The quality based resource allocation can also be combined with a quality based transmission scheduling. In such a case, mobile units experiencing a high quality are allowed to transmit more often in a period of time than mobile units with low quality.Type: GrantFiled: October 25, 2004Date of Patent: January 31, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Peter de Bruin, Ylva Timner, Tomas Jönsson

Patent number: 7876789Abstract: For some mobile communication services, a media stream such as video, will be combined with another media stream such as voice. For example, a user of a first terminal (101) is involved in a voice call over e.g. a circuit switched network (103) with a friend. During the voice call, the user of the first terminal decides to start transmitting another media stream, such as live streamed video, which may be transmitted over a packet switched network (104), to the friend's terminal (102). In such a case there is problem in that the two media streams voice and video may have quite different end-to-end time delays, i.e. the time from a part of the media stream is transmitted from the first user's terminal (101) until that part of the media stream is presented at the friend's terminal (102). Since comments from the first user will be presented to the user's friend earlier than the commented part of the video this will be quite annoying to the friend.Type: GrantFiled: June 23, 2005Date of Patent: January 25, 2011Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Per Synnergren, Stefan Wänstedt, Ylva Timner

Publication number: 20050159166Abstract: A quality of service profile for a mobile communication subscriber unit is determined and includes one or more mobile-specific desired quality of service parameters. Actual values for the service parameter(s) is(are) determined and fed back to a link quality controller to determine whether they are in an acceptable range or relationship with corresponding actual quality of service parameter values. A modulation and/or coding scheme for transmitting the information over the radio link is selected or adjusted based on whether the desired and actual quality of service parameters are in an acceptable range or acceptable relationship. A combined “desired” quality of service parameter using the first and second quality of service parameters (or more if desired) may be determined. A combined “actual” quality of service parameter using first and second actual quality service parameter values is determined.Type: ApplicationFiled: January 21, 2004Publication date: July 21, 2005Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Tomas Jonsson, Ylva Timner, Peter de Bruin, Johan Axnas
