Abstract: The present invention concern methods and apparatuses for handling public identities in an Internet Protocol Multimedia Subsystem, IMS, network. According to a method an HSS receives a request message from an S-CSCF. The request message includes a public identity. The HSS sends a response message including the registered wildcarded public identity to the S-CSCF if the request message includes an indication that the public identity is unregistered, the request message does not include a wildcarded public identity indication, and the public identity, included in the request message, matches with a wildcarded public identity, registered in the HSS. The S-CSCF is thus enabled to fetch a user profile using the wildcarded public identity.

Abstract: The present invention concern methods and apparatuses for handling public identities in an Internet Protocol Multimedia Subsystem, IMS, network. A CSCF node receives information indicating a set of distinct public identities, within a range of a wildcarded public identity, which set of distinct public identities are not in the same Implicit Registration Set (IRS) as the wildcarded public identity. The information is received from a Home Subscriber Server (HSS) node. The CSCF node stores the information indicating the set of distinct public identities, which are not in the same IRS, in the CSCF node for allowing matching of an originating request to the information indicating the set of distinct public identities, which are not in the same IRS.

Abstract: A method of handling IP Multimedia Public Identity registration within an IP Multimedia Subsystem network. The method comprises receiving at a Call Session Control Function a SIP REGISTER message including a completed IP Multimedia Public Identity Attribute-Value-Pair and no IP Multimedia Private Identity. The method further comprises deriving at the Call Session Control Function an IP Multimedia Private Identity using the IP Multimedia Public Identity and sending a Cx query from the Call Session Control Function to a Home Subscriber Server, the query including the IP Multimedia Public Identity and the derived IP Multimedia Private Identity. The Home Subscriber Server identifies a subsubscription using the IP Multimedia Public Identity, and determines that the derived IP Multimedia Private Identity is not associated with said subscription.

Abstract: According to an aspect of the present invention there is provided a method of obtaining authentication information for use in a Generic Bootstrapping Architecture, GBA, employed in a network with one or more GBA-capable subscriber registers and one or more GBA-incapable subscriber registers. The method involves a selection function for determining whether the authentication information of a subscriber is stored at a GBA-capable subscriber register or at a GBA-incapable subscriber register, and an inter working function for translating between the Diameter messages of the Zh interface and the MAP messages of the Zh? interface.

Abstract: Method and apparatuses for collecting user activity information in a telecommunications system. A first telecommunications node (120) handling signaling of the terminal of a user sends a message (516) notifying a registration event (515) of the user to a second node (130) handling registration information of said user. The message comprises an information element (ACT) indicating whether the user has been involved in a service provided during a registration period comprised between a previous registration event (501) of said user and said notified registration event. At reception of the message, the second node updates registration information (430) and activity information (440) of the user. By including service usage information in registration notification messages, the operator of the telecommunications system can obtain information about the rate of service usage in the system without requiring implementation of neither new nodes nor new messages to be exchanged by new or existing nodes.

Abstract: A service request (SRV) comprising a second identifier belonging to a collection of identifiers identified by a first identifier (WPSI-I) is rejected or allowed to proceed depending on whether the current usage data stored in relationship with the first identifier reaches a value established by usage limit data stored in relationship with said first identifier. Current usage data is updated according to service requests comprising a second identifier belonging to said collection and allowed to proceed. The usage limit data can state maximum number of simultaneous communications, or maximum number of second identifiers belonging to said collection, and can be dynamically updated according to traffic load conditions in an apparatus of the telecommunications system. The invention prevents overloading resources in telecommunications systems when the number of eventual users can not be foreseen.

Abstract: A single IMPI is determined, allowing the progress of a terminating call that addresses a given IMPU shared by more than one IMPI of an IMS subscription. A number of policies are applied per IMPI basis on how to progress the terminating call. A HSS is provided where the policies are configured and, a method is disclosed including IMPU with a number of policies. Additionally, the method may also include a step of configuring at the HSS the more than one IMPI with a priority indication usable to set the order in which the more than one IMPI are checked to determine at least one for which the policies allow to progress the terminating call.

Abstract: There is provided a method for handling subscriptions from a subscriber node (700) to changes in data relating to a user held at a database node (900) in a telecommunications system. At the subscriber node (700) a subscribe message is prepared (S1) comprising: first information identifying first data which the subscriber node (700) wishes to receive in a notification message in response to a change to the first data; second information identifying second data which the subscriber node (700) wishes to receive with such a notification message; and third information, different to the first information, specifying a condition to be fulfilled in relation to third data before such a notification message is sent. The first, second and third data each relate to the user and are held at the database node (900). The subscribe message is sent (S2) towards the database node (900). The subscribe message sent from the subscriber node (700) is received (S3) at the database node (900).

Abstract: A method of operating a Call Session Control Function node within an IP Multimedia Subsystem network. The method comprises establishing a first session corresponding to a first IP Multimedia Subsystem communication service using a first Application Server, receiving a request for a further session corresponding to a further IP Multimedia Subsystem communication service, and forwarding said request to a further Application Server. Said further Application Server is additionally notified that said first communication service is ongoing and of the nature of said first session.

Abstract: A method and apparatus for providing location information to a CSCF in an IMS network. An S-CSCF registers a first contact associated with an IMPU, and receives location information associated with the first contact. A second contact associated with the same IMPU, and also with a mobile access, is then registered at the S-CSCF. The S-CSCF receives location information associated with the second contact.

Abstract: A method and a HSS server allow the implicit registration of more than one IMS Private User Identity (IMPI), or the implicit registration of more than one contact address, or both, upon explicit registration of a subscriber with a given IMPI/IMPU (IMS Public User identity) pair and a given contact address. In particular, the method includes configuring subscriber data for the subscriber at the HSS with at least one implicit registration set selected from: a set of IMPIs associated with a given IMPI or with a given IMPU, and a set of contact addresses per IMPI basis; downloading from the HSS towards the S-CSCF the implicit registration set; and building up a corresponding data model therein.

Abstract: A method and apparatus for sharing an application profile for plural public IMS identities across different IMS subscriptions. A home application profile for a first public IMS identity (IMPUx) of a first IMS subscription, is stored in its entirety at a first HSS storage. A profile reference is stored as an abbreviated foreign application profile for a second public IMS identity (IMPUy) of a second IMS subscription at a second HSS storage. The profile reference points to the home application profile in the first HSS storage. An authorizing identifier for the second public IMS identity that authorizes access to the home application profile, is also stored at the first HSS storage.
