Publication number: 20110098059Abstract: A method and service-related nodes for providing a deferred distance notification for at least two user devices. A Location-based gateway receives a request for a deferred distance notification for user devices, and sends a request to a Location enabler for the location of the user devices. The gateway receives location data from the Location enabler, and monitors the fulfillment of user device distance-related event criteria. When a user device distance-related event criterion is fulfilled, the gateway triggers the deferred distance notification, and sends the notification of the user device distance event to an application node. The application node sends a location request after which the Application node receives the notification. Distance notification can thus be provided to a user requesting a location-deferred service, such that the location of entire groups of users can be revealed to the requesting party.Type: ApplicationFiled: October 23, 2009Publication date: April 28, 2011Inventors: Kermit Qiu, Bjorn Andersson, Vitomir IIic, Johan Bolin, Ake Busin

Publication number: 20100304707Abstract: In a method and arrangement for providing a reliable location for a communication terminal, a first location is obtained for the terminal by means of a first access mechanism. A second location is also obtained for the terminal by means of a second access mechanism, and the obtained first and second locations are then compared. The location of the terminal is validated if the obtained first and second locations are found to be substantially equal. Thereby, a more reliable location of the terminal can be used to support communication services requiring or needing such position information, such as emergency services. The validated location of the terminal can also be used for validating the location of an end point used by the terminal in an access network with fixed end points, or for validating a used positioning mechanism.Type: ApplicationFiled: August 14, 2006Publication date: December 2, 2010Inventor: Johan Bolin

Publication number: 20080002654Abstract: Methods and devices for encoding and decoding secure data entities are presented, which use at least parts of broadcast control messages (13) used by a cellular communications system (18) to which an intended user (10) is connected for obtaining suitable keys. Since the broadcast control messages (13) are sent continuously, the invention works without additional signaling when the application or content is actually used. The broadcast control messages (13) can also be different from time to time and/or from cell to cell, which opens up for usage restrictions both in space and in time. The present invention can also be operable on secure data entities provided in any transmission format supported by the user device (10), not only for secure data entities provided through the cellular communications system (18) itself.Type: ApplicationFiled: November 18, 2005Publication date: January 3, 2008Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventor: Johan Bolin

Publication number: 20070218920Abstract: A method and apparatus for obtaining the position of a calling subscriber terminal (400) connected to a fixed IP access network (402) at an end point. A Location Information Component LIC (404) including a radio receiver (404a) is placed in the vicinity of the end point to represent the position of the terminal. Broadcasted mobile network signals or satellite navigation signals are received, and position-related information is derived from the signals and added to a data stream (A1) from the terminal, before sending the stream over the IP access network. A centrally arranged Location Information Aggregator LIA (408) then receives the modified data stream (A2), extracts the position-related information, and associates location information on the terminal with a network address of the end point or an identity of the terminal. Thereby, reliable location information can be obtained for calling terminals to be available to a called party or used application.Type: ApplicationFiled: March 16, 2006Publication date: September 20, 2007Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventor: Johan Bolin

Patent number: 7194275Abstract: In a cellular communications network, additional control signals comprising virtual base station identification data are distributed in the radio system from well defined locations by e.g. transmitters. Since there is a connection between each virtual base station identification data and the location from where it is transmitted, a mobile terminal can use the information for improving its position estimation according to conventional procedures. No modifications of the mobile terminals are therefore necessary. The mobile terminal is not able to connect to the communications system using the virtual base station identification data, since this data only is intended for position estimating purposes. In such a way, the devices for providing the additional information necessary for the improved position estimation can be made very simple and inexpensive.Type: GrantFiled: September 30, 2004Date of Patent: March 20, 2007Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Johan Bolin, Rune Johansson, Ari Kangas
