Title (EN) METHODS AND APPARATUSES FOR FACILITATING P-CSCF RESTORATION WHEN A P-CSCF FAILURE HAS OCCURED
(FR) PROCÉDÉS ET APPAREILS POUR FACILITER LA RESTAURATION D'UNE P-CSCF LORSQU'UNE DÉFAILLANCE DE P-CSCF S'EST PRODUITE
Abstract:
(EN) A method of facilitating P-CSCF restoration when a P-CSCF failure has occurred is disclosed. The method comprises a Proxy Call Session Control Function, 'P-CSCF' receiving a Session Initiation Protocol, 'SIP', message when said P-CSCF has been selected as an alternative P-CSCF to a failed P-CSCF and providing, to an associated Policy and Charging Rules Function, 'PCRF', a message comprising an indication that P-CSCF restoration is required.
(FR) L'invention concerne un procédé pour faciliter la restauration d'une fonction proxy de commande de session d'appels (P-CSCF) lorsqu'une défaillance de P-CSCF s'est produite. Le procédé comprenant une P-CSCF consiste à recevoir un message de protocole de lancement de session (SIP) lorsque ladite P-CSCF a été sélectionnée en tant que P-CSCF alternative à une P-CSCF défaillante, et à fournir à une fonction de règles de politique et de taxation (PCRF) associée un message comprenant l'indication que la restauration de P-CSCF est nécessaire.
