Patent number: 10728819Abstract: A scenario may arise in which a circuit switched (CS) bearer reservation is successful but a voice media switching from packet switched (PS) to CS performed by a mobile switching center (MSC) server fails. Certain embodiments provides systems, apparatuses, and methods for recovery from such a scenario. A method, for example, can include determining whether session transfer of a user equipment is possible in response to a request from a network element to initiate session transfer of the user equipment and reporting to the requesting network element either a generic or specific indication that the transfer is not possible, when it is determined that the session transfer is not possible.Type: GrantFiled: January 9, 2013Date of Patent: July 28, 2020Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Curt Wong, Peter Leis, Jiadong Shen, Juergen Mayer

Method for re-assignment of S-CSCF services to registered IMS users of a home subscriber servers HSS
Patent number: 8934461Abstract: Re-assigning Serving Call Session Control Function, S-CSCF, services to a user of a Home Subscriber Server, HSS (200), in a Third Generation Partnership Program, 3GPP, telecommunications network is provided. In the case that S-CSCF services to the user including a registration procedure are previously assigned and access by the user to the S-CSCF services is erroneously lost, the proposal is to provide a method and means to re-assign those services. First, dynamic registration information (204) is uploaded from S-CSCF to the HSS (200) during the registration procedure. Then, the dynamic registration information (204) is stored from HSS (200) to S-CSCF (203) during a re-assignment procedure of the user.Type: GrantFiled: October 17, 2007Date of Patent: January 13, 2015Assignee: Nokia Solutions and Networks GmbH & Co.
