Abstract

The invention relates to methods, IMS system, and nodes such as P-CSCF, I-CSCF and S-CSCF for bypassing a network node, such as the HSS, during a reregistration procedure. Communication links are monitored and if a probability of success of a new request to the network node is within a range, then the network node can be bypassed.
