Abstract
Techniques are described herein for providing improved service call session restoration. In embodiments, such techniques may comprise storing, at a home subscriber server (HSS), information about a proxy call session control function (P-CSCF) node. The HSS may then receive an indication that a first service call session control function (S-CSCF) node is unresponsive. Upon receiving such an indication, the techniques may comprise determining, based on a user profile, that the first S-CSCF node is associated with the P-CSCF node; selecting, based on the information about the P-CSCF node, a second S-CSCF node to be associated with the P-CSCF node; and providing, by the HSS, at least a portion of the information about the P-CSCF node to the second S-CSCF node. The second S-CSCF node can then be configured to replace the first P-CSCF node using that information.
