Patent number: 8320260Abstract: A wireless communication network automatically tests itself for sleeping cells. This is done by designing the base stations to regularly act as a terminal, contact its neighboring base stations and as a mobile perform a set of typical traffic cases. From the outcome of the traffic cases the probing base station detects neighboring base stations that cannot carry traffic. The information about sleeping cells is subsequently communicated from the base station to the operation and maintenance system.Type: GrantFiled: September 5, 2007Date of Patent: November 27, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Erik Lars Westerberg, Kenneth Balck, Anna Pucar Rimhagen

Patent number: 7940718Abstract: A first radio base station (RBS) is operated to cause trace log information to be supplied to a trace log storage node. The RBS becomes responsible for serving a user equipment session, and at some point begins a trace process. When the session report criterion has been satisfied, a trace status indication is alternatively sent to or received from a second radio base station, the trace status indication including an indicator of a session report cause and a time of satisfying the session report criterion. The indicator of the session report cause and the time of satisfying the session report criterion are used to identify a set of trace log information stored in a record buffer. If not empty, the set of trace log information is supplied to the trace log storage node.Type: GrantFiled: March 11, 2008Date of Patent: May 10, 2011Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Andreas Olsson, Kenneth Balck

Publication number: 20100273451Abstract: In one aspect of the invention presented herein, a mobile terminal requests positioning assistance data from its supporting wireless communication network, in response to receiving a positioning request from a positioning node. Further, in response to receiving the positioning assistance data from the network, the mobile terminal sends the positioning assistance data to the positioning node. In this manner, the positioning node advantageously gains access to network-generated positioning assistance data without need for requesting it from the network. In at least one embodiment, the mobile terminal receives the positioning request from the positioning node over a User Plane (UP) connection. However, the mobile terminal sends the positioning assistance data request to the base station over a Control Plane (CP) connection, and receives the requested positioning assistance data via the CP. The terminal transfers that data to the UP and sends it to the positioning node.Type: ApplicationFiled: June 29, 2009Publication date: October 28, 2010Inventors: Joakim Bergström, Kenneth Balck, Ake Busin, Tao Cui, Martin Israelsson, Tarmo Kuningas, Janne Peisa, Elena Voltolina

Patent number: 7742418Abstract: The technology in this application determines the throughput over a data communication substantially as experienced by a user receiving the data. The determined throughput is substantially independent of the total amount of data transferred over the connection. This “active” throughput measure is divided into two parts to provide two performance measures: transfer throughput and latency. Latency corresponds to a time period needed to accomplish one or more functions associated with the data connection, like setting up and taking down the connection, during which payload type data to be transferred to an end user is not transferred. By identifying and removing the initial latency from the throughput determination for the data connection, the determined transfer throughput provides a more accurate measure of the throughput actually experienced by the end user.Type: GrantFiled: August 24, 2007Date of Patent: June 22, 2010Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lars Erik Westerberg, Kenneth Balck, Martin Skarve, Mikael Soderstrom

Patent number: 6529497Abstract: A telecommunications system (18) comprises a control node (24) and a base station node (22). The control node (24) maintains a first list (42) of idle radio channels which is consulted in order to obtain channels for a first type of telecommunications service. A second list (56) of idle radio channels is maintained for a specialized telecommunications service, the idle radio channels of the second list being radio channels which are unallocated with respect to the specialized telecommunications service but yet activated (e.g., having an established transmission path and synchronization). The second list of idle radio channels is initially consulted in order to obtain channels for the specialized telecommunications service. If no channels are available for the specialized telecommunications service on the second list, idle channels from the first list are adapted and utilized for the specialized telecommunications service. The specialized telecommunications service preferably involves packet data transfer (e.Type: GrantFiled: September 17, 1999Date of Patent: March 4, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Suzanne Hjelm, Kenneth Balck
