20090097398 | FAILURE RECOVERY IN AN IP MULTIMEDIA SUBSYSTEM NETWORK - A method and apparatus for facilitating recovery from the failure of a Serving Call Session Control Function (S-CSCF) within an IP Multimedia Subsystem (IMS) network. A Proxy Call Session Control Function (P-CSCF) receives a SIP request sent by a User Equipment (UE) having an identity previously registered with the IMS network and for which a given S-CSCF was allocated. The P-CSCF determines whether the given S-CSCF has failed or is otherwise unreachable. If so, the P-CSCF sends a re-registration message to the UE. Receipt of the re-registration message at the UE forces the UE to perform an IMS registration procedure with the IMS network. | 04-16-2009 |

20090215454 | Method and Apparatus for use in a Communications Network - A method and apparatus for registering a mobile node such as a User Equipment (UE) of a UMTS telecommunications network with a subsystem of the network such as an IP Multimedia Subsystem (IMS). A Policy and Charging Rules Function (PCRF) node provides policy and charging rules, and a Gateway GPRS Support Node (GGSN) enforces the rules for traffic flows. The UE sends a registration request to the GGSN, which selects a PCRF. When a Proxy Call Session Control Function (P-CSCF) receives the registration request, the P-CSCF selects a candidate PCRF and validates the selection. If the candidate PCRF is the PCRF selected by the GGSN, the registration is successful. If not, the P-CSCF may select another PCRF and repeat the validation process. | 08-27-2009 |
20100088421 | Evaluating Initial Filter Criteria - A method of evaluating Initial Filter Criteria (IFC) at a terminating Serving Call Session Control Function (S-CSCF) in an IP Multimedia Subsystem network. Upon receiving a Session Initiation Protocol (SIP) message containing a destination Uniform Resource Identifier (URI), the S-CSCF applies an Initial Filter Criterion to the message, sends the message to an Application Server (AS), and suspends further IFC evaluation. When a return message is received from the AS, the S-CSCF determines whether the AS changed the URI. If so, the S-CSCF makes a determination of whether to resume IFC evaluation. If the AS did not change the URI, the S-CSCF resumes IFC evaluation. | 04-08-2010 |

20110128843 | FAILURE RECOVERY IN AN IP MULTIMEDIA SUBSYSTEM NETWORK - A method is provided for facilitating recovery from the failure of a P-CSCF within an IP multimedia Subsystem network. A gateway, such as a GGSN, monitors signals arriving at the gateway from the P-CSCF and provides an indication if the monitored signals become unacceptable, for example because of an interruption in the signals. The gateway responds by signalling the unavailability of the P-CSCF to user equipment, which was associated with the P-CSCF during a previous registration with the IMS network. In response, for example, the user equipment affected by the failure may request re-registration with the IMS network using a different available P-CSCF. | 06-02-2011 |
20120117624 | Method and Apparatus for use in an IP Multimedia Subsystem - A method is provided for use in an IP Multimedia Subsystem, IMS, in which a Serving 5 Call Session Control Function, S-CSCF, of the IMS cooperates with a Home Subscriber Server, HSS, of the IMS, to lock a user following a predetermined number of failed authentications of the user at the S-CSCF and/or to unlock that user thereafter, with any request received from the user at a node of the IMS where the lock is in effect and requiring an authentication challenge being caused by the node to be rejected. In one example, a locking signal is sent from the S-CSCF to the HSS, following the predetermined number of failed authentications, to indicate to the HSS that the user should be locked at the HSS. The locking signal could be carried by a Server Assignment Request, SAR, message. In another example, the user is unlocked at the S-CSCF in response to receipt of an unlock signal sent from the HSS to the S-CSCF. The unlock signal could be carried by a Registration Termination Request, RTR, message. | 05-10-2012 |
