Abstract
Provided are request processing method, network node, and computer-readable storage medium. The method for I-CSCF includes receiving a first registration refresh request transmitted by P-CSCF, the first registration refresh request is generated by P-CSCF based on a second registration refresh request transmitted by UE, and the first registration refresh request includes historical registration information corresponding to UE. The historical registration information carries address information of a registration server that is cached by P-CSCF in the case that a last registration is successful. Transmitting the first registration refresh request to S-CSCF based on the historical registration information in the first registration refresh request. The influence of situations such as signaling surge, congestion, and service interruption, etc., on request processing can be overcome, network robustness can be improved, and network performance can be optimized, thereby ensuring normal network service.
