    摘要: 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). 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, application server, and Serving Call/Session Control Function (S-CSCF) for allocating a SIP Application Server to a subscriber in an IP Multimedia Subsystem. A Home Subscriber Server (HSS) identifies for the subscriber, a set of provisioned initial filter criteria, which contains at least one generic SIP Application Server identity. The HSS sends the filter criteria to an S-CSCF allocated to the subscriber. The S-CSCF resolves the generic SIP Application Server identity into a plurality of application server addresses, with one of the addresses being allocated to the subscriber for use in provisioning a service to the subscriber. The S-CSCF caches the address allocated to the subscriber for subsequent use.

    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).
