Patent number: 11381964Abstract: A cellular terminal detects any capability reporting trigger and responsively to such determination produces a cellular network authentication capabilities message indicative of cellular network authentication capabilities available for the terminal; and transmits the cellular network authentication capabilities message to the cellular network. The cellular network receives the network authentication capabilities message from a cellular terminal, selects a cellular authentication algorithm based on capabilities indicated by the network authentication capabilities message; and performs cellular authentication with the cellular terminal using the selected cellular authentication algorithm.Type: GrantFiled: May 20, 2014Date of Patent: July 5, 2022Assignee: Nokia Technologies OyInventors: Hannu Bergius, Silke Holtmanns

Patent number: 9918292Abstract: A method, apparatus and computer program product are described for reducing delay when making a network connection between user equipment (UE) and a network node when a tracking area update (TAU) request has been denied during LTE reselection. Following a revised signaling protocol, a UE can avoid activation of a NAS Attach Retry timer and move directly to establishing a connection to the network, reducing the UE communications delay from about eleven seconds to less than one second.Type: GrantFiled: May 6, 2013Date of Patent: March 13, 2018Assignee: Nokia Technologies OyInventors: Jarkko Koskela, Hannu Bergius, Jorma Kaikkonen, Ari Laukkanen

Patent number: 9820327Abstract: Methods and apparatus, including computer program products, are provided for delaying a service request. In one aspect there is provided a method. The method may include receiving, at a user equipment, a message including a service rejection sent by a network; starting a timeout period in response to the received message including the service rejection; and waiting to send an attach request to the network until at least one of a radio resource control connection release is received from the network or the timeout period expires. Related apparatus, systems, methods, and articles are also described.Type: GrantFiled: October 15, 2012Date of Patent: November 14, 2017Assignee: Nokia Technologies OyInventors: Hannu Bergius, Jussi-Pekka Koskinen, Jarkko Tuomo Koskela, Jorma Kaikkonen

Publication number: 20160157142Abstract: A user equipment is initially camped on an LTE/E-UTRAN cell (205). An eNodeB informs (210) the UE to return after circuit-switched fall-back, CSFB, and optionally provides re-direction/re-selection information. The UE then performs a CSFB (215) with a NodeB of a legacy network cell, such as GERAN/UTRAN/CDMA2000 cell. Upon release of the CSFB connection (220), the UE uses (230) the received re-direction information to identify a best cell candidate in LTE, and select back (235) to the LTE/E-UTRAN carrier.Type: ApplicationFiled: July 3, 2013Publication date: June 2, 2016Inventors: Jussi-Pekka Koskinen, Hannu Bergius, Jorma Kaikkonen
