摘要:
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.

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.

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.

The present invention faces the issue of exercising a parental control over children's activities in the IMS network, in terms of registering into the IMS network as well as in terms of call establishment, and provides for a new IMS subscription model supporting a hierarchy of IMPI's, so-called ‘primary’ IMPI's and so-called ‘secondary’ IMPI's, whereby only the primary IMPI's are allowed to register themselves, whereas the secondary IMPI's can only register themselves after having been previously registered by a primary IMPI. To this end, the present invention provides for a new method and an enhanced HSS to allow the implicit registration of one or more ‘secondary’ IMPI's upon the explicit registration of an IMS subscriber with a given IMPI/IMPU pair, wherein the given IMPI is a ‘primary’ IMPI and the given IMPU is associated with a registration set of IMPI's which includes said one or more ‘secondary’ IMPI's.
摘要:
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.

Methods and apparatus facilitate recovery of an IMS in which an S-CSCF has suffered a restart (after a failure, software upgrade, or other reasons). One or more of first and second methods comprise submitting, from the S-CSCF towards a HSS, contact data required by the S-CSCF to contact a given subscriber, or to contact a proxy server through which the subscriber is accessible; storing the contact data at the HSS; and providing from the HSS towards an IMS entity, which may be previously assigned S-CSCF or a new S-CSCF, contact information elements selectable from the contact data.
摘要:
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.

A Home Subscriber Server for handling IP Multimedia Subsystem subscriptions comprises means for maintaining associations between public user identities and Service Profiles, where two or more public user identities can be associated with a common Service Profile, and means for identifying to a network node all public user identities that are associated with a common Service Profile.
