    摘要: 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.

    摘要: The present invention is aimed to provide means and methods for recovery of the IMS where an S-CSCF has suffered a restart after a failure, software upgrade or other reasons. To this end, the present invention provides for a first method to be applied in a HSS holding subscriber data for subscribers of the IMS and a second method to be applied in a S-CSCF selected for serving a given subscriber, upon restart of a S-CSCF assigned for serving a given subscriber. Both first and second methods cooperating to submit from the S-CSCF towards the HSS contact data required by the S-CSCF to contact the given subscriber, or to contact a proxy server where the subscriber is accessible through; storing the contact data at the HSS; and providing from the HSS towards an IMS entity, which may be the previously assigned S-CSCF or a new S-CSCF, contact information elements selectable from the contact data.

    摘要: A method of registering or deregistering a user to or from an IP Multimedia Subsystem (IMS) network. A SIP Application Server (SIP-AS) performs a registration or deregistration with the IMS network on a user's behalf. The registration or deregistration is performed over one of the following interfaces: a Service Control Interface (ISC) with a Serving Call State Control Function (S-CSCF), a Gm interface with a Proxy CSCF (P-CSCF), or an Ma interface with an Interrogating CSCF (I-CSCF).

    摘要: A method of initiating an IP Multimedia Sub-system communication for a user that is not registered a priori with the IP Multimedia Subsystem. The method comprises receiving a communication request from said user at a Session Initiation Protocol Application Server via an interface to an external network or receiving an internally or externally generated stimulus requiring the establishment of an IP Multimedia Subsystem communication, allocating a Serving Call/State Control Function to the user, forwarding a SIP request from the Application Server to the allocated Serving Call/State Control Function, and establishing the requested communication.

    摘要: In one aspect, the invention provides a method, and associated apparatus for re-registering a contact address of a user of an IP Multimedia Subsystem, IMS, network. A request for re-registration of the contact address is received at a Serving-Call Session Control Function, S-CSCF, node serving the user. After a determination that the S-CSCF has no stored information relating to the contact address, a request is sent to a Home Subscriber Server, HSS, of the user to register the contact address information. The HSS detects if the contact address information relating to the user has already been backed-up by the HSS, and notifies the node serving the user of registered contact address information backed-up by the HSS. Another aspect provides a method and associated apparatus for de-registering a registered contact address of a user of an IP Multimedia Subsystem, IMS, network.
