The method also comprises the step (S2) of receiving information representing the identity of the second cell selected by the UE (e.g. CGI), and the step (S3) of identifying, based on the received information representing the identity of the second cell and information representing the identity of the first cell, a neighbor cell relation between the first cell and the second cell.Type: GrantFiled: June 18, 2014Date of Patent: June 5, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Lena Melin, Sofia Brismar

Patent number: 9955392Abstract: Techniques for use in selecting a base station transceiver system for communication with a mobile station are described. The mobile station is connected to a first base station transceiver system, and scans to identify a second base station transceiver system for communication. The mobile station further identifies that the second base station transceiver system provides a predetermined communication service, and that the first base station transceiver system fails to provide the predetermined communication service. In response to identifying, the mobile station causes the second base station transceiver system to be selected for communication over the first base station transceiver system even if the signal quality of the second base station transceiver system is worse than that of the first base station transceiver system.Type: GrantFiled: April 4, 2017Date of Patent: April 24, 2018Assignee: BlackBerry LimitedInventors: Muhammad Khaledul Islam, Asif Hossain

Patent number: 9949185Abstract: Mobile service anchor management (MSAM) is facilitated. MSAM is an anchor management function/system for radio frequency (RF) access configuration/reconfiguration over the downlink, and uplink separated novel frequency division duplex systems. One method comprises determining, by a MSAM system comprising a processor, that a mobile device communicatively coupled to a first network device is associated with a region in which the first network device fails to have line of sight communication with the mobile device; and assigning, by the mobile service anchor management system, the mobile device to a second network device determined to have the line of sight communication for the region. Millimeter watt (mmW) BS devices and devices that operate on other RF bands can be utilized.Type: GrantFiled: October 8, 2015Date of Patent: April 17, 2018Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Yuang Lou, Douglas A.

Patent number: 9775183Abstract: A radio communication system and a method for assigning a short-lived Cell Radio Network Temporary Identifier, “CRNTI”, to a first user equipment performing random access to a radio network node are provided. The radio communication system registers the first user equipment as connected to the radio network node. A message for synchronizing the radio network node and the first user equipment with respect to the first time period is transferred. After the first time period has elapsed, the radio communication system maintains the first user equipment connected to the radio network node, and allows the short-lived CRNTI to be assigned to a second user equipment.Type: GrantFiled: January 3, 2012Date of Patent: September 26, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: György Miklós, Erik Eriksson, Johan Rune, Joachim Sachs, Zoltán Turányi, Niclas Wiberg
