20090073964 | Providing services in case of call diversion in a communication system - The present invention relates to an S-CSCF receiving a terminating request associated with a called user and executing services for the called user. The S-CSCF determines an indication in Session Case indicating originating services handling in call forwarding situation, and based on this executes a subset of services for the user. | 03-19-2009 |
20100232368 | METHOD FOR MULTIPLE REGISTRATION OF A MULTIMODAL COMMUNICATION TERMINAL - For multiple registration of a multimodal communication terminal (MKE) via at least one access network in an IMS-based service communication system in a mobile and/or convergent communication system, where the multimodal communication terminal (MKE) is registered for at least one communication service via a first access network (WIAN) in at least one service control unit in the IMS-based service communication system (S-CSCF), a registration message with an access network identifier (ZK) is produced and is transmitted to the at least one service control unit (S-CSCF) in the IMS-based service communication system. The at least one service control unit evaluates the access network identifier (ZK) and takes it as a basis for performing further registration of the multimodal communication terminal in the IMS-based service communication system (S-CSCF). | 09-16-2010 |
20120131167 | Method and Apparatus for User Registration in IMS - A method for user registration in Internet protocol multimedia subsystem is provided including receiving a registration request including a first identification of a control function, comparing said first identification of the control function with a second identification of the control function, and proceeding with the registration request based on the result of said comparing. | 05-24-2012 |
20130084860 | MINIMAL ACCESS TRANSFER CONTROL FUNCTION REQUIREMENTS FOR SINGLE RADIO VOICE CALL CONTINUITY HANDOVER - A method, apparatus, and computer readable medium is provided for a reverse single radio voice call continuity handover procedure, where an access transfer control function is only allocated dynamically during a call setup phase, if the access transfer control function is needed to support the reverse single radio voice call continuity handover procedure. | 04-04-2013 |
20130148550 | Method and Apparatus for Registration of an Emergency Service in Packet Data Connections - The invention relates to a session control entity, a method and a computer program product for assigning for a user, during establishment of a packet data connection, an interne protocol (IP) address allocated for an emergency packet data connection if the packet data connection is an emergency packet data connection. | 06-13-2013 |
20130212284 | METHOD AND APPARATUS FOR MAINTAINING INFORMATION ABOUT SUBSCRIPTION SERVERS - The invention relates to transferring subscription data of a user from a first subscription server to a second subscription server, and involving the first subscription server in handling of terminating requests to the user, until the user performs registration procedure, and involving the second subscription server in handling of terminating requests to the user, after the user has performed the registration procedure. | 08-15-2013 |
20130336225 | METHOD AND APPARATUS FOR TRANSMITTING A NETWORK IDENTITY - The invention relates to a session control entity, method and computer program for receiving an indication indicating a network where an access network entity for a user is located, transmitting a message for establishing a session for the user, and, including the indication indicating the network in the message. | 12-19-2013 |
20150200946 | SECURITY FOR ACCESS TO THE IP MULTIMEDIA SUBSYSTEM (IMS) WITH WEB REAL TIME COMMUNICATION (WebRTC) - Systems, methods, apparatuses, and computer program products for providing security between WebRTC clients and IMS are provided. One method includes storing, by a network node, at least one parameter per internet protocol multimedia subsystem (IMS) subscription, where the at least one parameter comprises at least one identity of any web real time communication (WebRTC) web server function that is authorized to authenticate an IMS subscriber in WebRTC. The method may further include receiving a WebRTC web server function identity from a call state control function, comparing the received WebRTC web server function identity with the at least one parameter associated with the IMS subscription, and rejecting IMS communication when there is not a match between the received WebRTC web server function identity and the at least one parameter associated with the IMS subscription. | 07-16-2015 |
