Patent number: 9413561Abstract: A subscriber server routes a terminating call in a network that includes a circuit switched (CS) network, a packet switched (PS) network, and an IP Multimedia Subsystem (IMS). The server receives a request for routing information in relation to the terminating call from a CS node in the CS network. A determination is made at server based on whether a UE associated with the terminating call is registered in the IMS and the UE has access to the PS network. The server instructs the CS node to route the terminating call in the CS network when the UE is not registered in the IMS or when the UE does not have access to the PS network. The server instructs the CS node to send the terminating call to the IMS for handling when the UE is registered in the IMS and when the UE has access to the PS network.Type: GrantFiled: June 27, 2011Date of Patent: August 9, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ralf Keller, Afshin Abtin, Fredrik Lindholm, David Castellanos Zamora, Juan Manuel Fernandez Galmes, Antonio Alonso Alarcon

Patent number: 8782208Abstract: A method is disclosed for use by an Interrogating Call/Session Control Function (I-CSCF) of an IP Multimedia Subsystem (IMS). In the method, a Session Initiation Protocol (SIP) message is received by the I-CSCF, which the I-CSCF attempts to forward to a Serving Call/Session Control Function (S-CSCF) of the IMS assigned to provide services to a user. If the attempt is determined to have failed, the I-CSCF sends a message to a Home Subscriber Server (HSS) of the IMS to request capabilities information for selecting a S-CSCF, the request message also providing first information relating to the status of the assigned S-CSCF. On receipt of the capabilities information at the I-CSCF from the HSS, the I-CSCF selects a replacement S-CSCF to provide services to the user. Related methods are also disclosed for use by the HSS and S-CSCF.Type: GrantFiled: July 23, 2007Date of Patent: July 15, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Maria Carmen Belinchón Vergara, Germán Blanco, Juan Manuel Fernandez Galmes, Hubert Przybysz, Andreas Schumacher, Stephen Terrill

Patent number: 8510457Abstract: A generic method is described for storing data in the HSS (2) by the S-CSCF (1) of an IMS. When a SIP message containing new information relating to an IMPI/IMPU pair is received by the S-CSCF (1), a data package is created for storage at the HSS (2), containing the new information. An SAR command is sent to the HSS (2) containing an AVP including an instruction to the HSS (2) and the new data package. In one aspect a unique data package is controlled by the S-CSCF (1). When new information relating to the IMPI/IMPU is received in a SIP message, this is added to any previously sent data package to create a new data package. In another aspect the HSS (2) controls a unique data package, returning the data package to the S-CSCF (1) to be amended if necessary. In another aspect separate data packages are used.Type: GrantFiled: November 30, 2007Date of Patent: August 13, 2013Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Maria-Carmen Belinchón Vergara, Hubert Przybysz, Juan Manuel Fernandez Galmes

Publication number: 20100217875Abstract: A method is disclosed for use by an Interrogating Call/Session Control Function (I-CSCF) of an IP Multimedia Subsystem (IMS). The method comprises, in response to receipt of a Session Initiation Protocol (SIP) message, requesting capabilities information relating to a user from a Home Subscriber Server (HSS) of the IMS. On receipt of the capabilities information from the HSS, a primary and a secondary Serving Call/Session Control Function (S-CSCF) of the IMS are selected to provide services to the user. In one embodiment, the I-CSCF attempts to forward the SIP message to the primary S-CSCF with information relating to the secondary S-CSCF, such that the information can be provided subsequently to the HSS. If the attempt is determined to have failed, the SIP message can be forwarded to the secondary S-CSCF instead. Methods are also disclosed for use by the S-CSCF and the HSS.Type: ApplicationFiled: July 23, 2007Publication date: August 26, 2010Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Maria-Carmen Belinchón Vergara, Juan Manuel Fernandez Galmes, Santiago Munoz Munoz
