    摘要: The present invention provides a call session control server assignment method and system for equalizing loads of a plurality of call session control servers (S-CSCF servers). For this end, the HSS server 40 is provided with an S-CSCF selection table 41A that stores priority information indicating the order of priority at the time of assigning user equipment in response to the current operation condition of the plurality of S-CSCF servers 20, 21, 22 and the like in correspondence with the respective S-CSCF servers. When an interrogating call session control server (I-CSCF server) 30 sends an interrogation to the HSS server 40 for determining a particular S-CSCF server for registering the user equipment and administering a call session control for the user equipment at the registration time of the user equipment, a reference is made to the S-CSCF selection table 41A for selecting a particular S-CSCF server to be assigned in response to the current operation condition of the respective S-CSCF servers 20, 21, 22 and the like and also the information in the S-CSCF selection table 41A is sent back to the I-CSCF server 30.
