Patent number: 10506421Abstract: A method and corresponding apparatus are configured to transmit, during terminal attachment to an evolved packet system and in at least a portion of a diameter command, centralized service-related subscription information. The method and apparatus are also configured to transmit, in an initial message of a call continuity procedure, received centralized service-related subscription information. The method and apparatus are configured to operate according to the received centralized service-related subscription information in the initial message of the call continuity procedure.Type: GrantFiled: August 14, 2018Date of Patent: December 10, 2019Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Lauri Kalevi Lahtinen, Juha Matias Kallio, Miikka Juhana Poikselka, Markku Ahti Tuohino

Patent number: 10225765Abstract: Certain networks can operate using circuit switched infrastructure, while other networks may operate using infrastructure for the long term evolution (LTE) of the third generation partnership project (3GPP). Devices can operate across the boundaries of these networks. Thus, such devices as well as the networks may benefit from network sharing in reverse single radio voice call continuity. For example, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include providing a network identification corresponding to the source network while requesting the handover. Alternatively, or in addition, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include determining the target network based on a network identification received previously.Type: GrantFiled: October 9, 2013Date of Patent: March 5, 2019Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Curt Wong, Lauri Kalevi Lahtinen

Patent number: 9838343Abstract: A method, apparatus, and computer program for control of a text component of a call. The method may include sending a message to a node for establishment of a call in an area, the area providing at least partially overlapping packet switched and circuit switched coverage. The message may include a request for one of a packet switched real-time text component and a circuit switched real-time text component in said call. In response to receiving a message from the node, the method may include sending a further message to the node including a request to provide the other of a packet switched real-time text component and a circuit switched real-time text component in the call.Type: GrantFiled: January 22, 2014Date of Patent: December 5, 2017Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Juha Matias Kallio, Lauri Kalevi Lahtinen, Vesa Tapani Tiainen

Patent number: 9420443Abstract: Communication systems may benefit from various aspects of emergency call handing. For example, wireless communication systems may benefit from clean up with respect to a fast return feature applied to an emergency call using circuit switched fallback, without a location area update. A method may include identifying an emergency communication that is a circuit switched fallback communication of a user equipment. The method may also include configuring communications so that mobile terminated services work properly after completion of the emergency communication. More particularly, for example, a method may include determining in a network element that the emergency communication is a circuit switched fallback communication. The method may also include, when the emergency call is ended, avoiding invoking a fast return feature for the user equipment.Type: GrantFiled: January 18, 2013Date of Patent: August 16, 2016Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Curt Wong, Devaki Chandramouli, Laszlo Janosi, Lauri Kalevi Lahtinen

Patent number: 8335485Abstract: Embodiments provide a method and apparatus wherein a proxy control function may forward an emergency session to a serving control function, the serving control function forwarding the session to a default emergency control function. The default emergency control function may return an address or identity of an emergency control function or may forward the session to an emergency control function.Type: GrantFiled: June 11, 2008Date of Patent: December 18, 2012Assignee: Nokia CorporationInventors: Markku Ahti Tuohino, Lauri Kalevi Lahtinen

Publication number: 20110201342Abstract: A method can include allocating a temporary mobile subscriber identity for a user equipment during a location update procedure. The method can also include allocating, during the allocating of the temporary mobile subscriber identity, a unique network resource identifier value for the whole network element, wherein temporary mobile subscriber identity allocation avoids being location area based. The method can further include providing, to the user equipment, a location area identifier, temporary mobile subscriber identity with the unique network resource identifier value, and an indication to skip location area identifier checking when performing circuit-switched fallback. Certain embodiments of the present invention can thus minimize the LAU by the UE and allow the network not to require perfect alignment of TA and LA.Type: ApplicationFiled: February 16, 2010Publication date: August 18, 2011Applicant: NOKIA SIEMENS NETWORKS OYInventors: Curt WONG, Lauri Kalevi LAHTINEN, Robert ZAUS
