20090202047 | Implicit emergency registration set - A method for providing an implicit emergency registration set is disclosed. The method can include initiating an identifier selection procedure. The method can also include identifying whether a user has a dedicated emergency telephone uniform resource identifier (tel URI), and, if so, selecting it. The method can further include identifying, when the user does not have a dedicated emergency tel URI, whether the user's internet protocol (IP) multimedia private identity (IMPI) is known. The method can additionally include identifying, when the user's IMPI is known, whether the user's IMPI has a non-shared tel URI, and, if so, selecting it, but otherwise selecting a tel URI of the user's IMPI. The method can also include identifying, when the user's IMPI is not known, whether a shared tel URI is available, and selecting it if it is, otherwise selecting a tel URI from a non-shared set. | 08-13-2009 |
20100011004 | Service Identification Optimization - A network element comprising a storage configured to maintain downloaded service profiles; a data base configured to maintain a list of identifiers of downloaded service profiles; and a correspondence processor configured to check the availability of a downloaded service profile by referring to the list of identifiers. | 01-14-2010 |
20110264747 | INTERWORKING BETWEEN MESSAGING SERVICES - In a service level interworking unit, a service center (SC) address or a set of SC addresses dedicated for the service level interworking is used whenever an instant message (IM) is interworked to a short message (SM). In other words, if a message is initially sent as an instant message (IM) by user equipment (UE) and is interworked to a short message (SM) by the interworking function, the interworked short message (SM) is sent to a dedicated service center (SC) address. For originating messages that are not interworked, different service center address or addresses are used. A terminating short message (SM) received at the interworking unit is interworked to an instant message (IM) and the interworked instant message (IM) is delivered to the user equipment (UE), if a service center address in the terminating short message (SM) is one of the dedicated service center addresses. If the a service center address in the terminating short message (SM) is not one of the dedicated service center addresses, the terminating short message (SM) is delivered to the user equipment (UE) without a service level interworking. | 10-27-2011 |
20110280383 | DELIVERY OF SHORT MESSAGES - Methods, apparatuses, system and a computer program product provide improved delivery of short messages. The method includes the steps of receiving a message to be delivered to user equipment, negotiating a timer value with a short message service routing element, forwarding the short message to the short message service routing element together with the negotiated timer value and starting a timer according to the negotiated timer value. | 11-17-2011 |
20120218920 | Emergency Service in Communication System - The invention relates to an apparatus, method and a computer program product for establishing a request for a session by an application server, determining by an emergency related local service function that the session includes an emergency session, wherein the emergency related local service function is co-located at the application server, and, transmitting the request for the session to an emergency call state control function of the internet protocol multimedia subsystem based on the determination. | 08-30-2012 |
20130097331 | Submit Report Handling In SMSIP - Submit report handling in Short Message Session Initiation Protocol (SMSIP) is provided. For example, a method can include preparing a submit report, wherein the preparing includes using a combination of forking and an in-reply-to header to find an appropriate terminal. The method can also include sending the submit report to the appropriate terminal. Likewise, another method can include receiving, by an apparatus, a session initiation protocol message request including a submit report. The method can also include processing the submit report to determine whether the request corresponds to a message sent by the apparatus. The method can further include sending, when the submit report is determined not to correspond to any message sent by the apparatus, a not-acceptable-here session initiation protocol response. The method can additionally include sending, when the submit report is determined to correspond to the message sent by the apparatus, an ok session initiation protocol message. | 04-18-2013 |
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 |
20130201879 | Method and Apparatus for Maintaining a Registration for an Emergency Service - The invention relates to a session control entity, subscription entity, methods and computer programs for transmitting a request to terminate a registration of a user, determining if the user is registered for an emergency service, for maintaining the user registered for the emergency service, if based on the determination the user is registered for the emergency service, and transmitting an indication indicating that the user is registered for an emergency service if based on the determination the user is registered for the emergency service. | 08-08-2013 |
