step 201, a User Equipment (User Equipment, abbreviated as UE) sends an initial registration request to an Interrogating Call Session Control Function (I-CSCF).
In this embodiment, the sending of the initial registration request to the I-CSCF by the UE specifically includes: the UE sends the initial registration request to a Session Border Controller (SBC), and the SBC sends the initial registration request to the I-CSCF.
Step 202, I-CSCF sends User Authorization Request (UAR for short) to DRA.
In this embodiment, the UAR is specifically a set of capabilities that requests multiple Call Session Control functions (Serving Call Session Control functions, abbreviated as S-CSCF).
Step 204, the primary HSS sends a User Authorization Answer (UAA) message to the DRA, where the UAA message carries multiple capability sets corresponding to multiple candidate S-CSCFs.
For example: 3 candidate S-CSCFs (S-CSCF1, S-CSCF2 and S-CSCF3) are available for selection, and the corresponding capability sets of the S-CSCF1 are 1, 2 and 3; the capability set corresponding to the S-CSCF2 is 1, 2, 3, 100; the S-CSCF3 corresponds to capability sets 1, 2, 3, 4.
Step 205, DRA sends UAA message to I-CSCF.
And step 206, the I-CSCF screens out an appointed capability set meeting the preset capability requirement from the plurality of capability sets and acquires an S-CSCF corresponding to the appointed capability set.
In this embodiment, the I-CSCF filters out a designated capability set meeting a preset capability requirement from a plurality of capability sets, for example: the preset capability requirements of the I-CSCF are 1, 2 and 100; the 3 candidate S-CSCFs and their corresponding capability sets are: the capability set corresponding to the S-CSCF1 is 1, 2, 3; the capability set corresponding to the S-CSCF2 is 1, 2, 3, 100; and if the capability set corresponding to the S-CSCF3 is 1, 2, 3 or 4, the capability set corresponding to the S-CSCF2 is an energy level set meeting the preset capability requirement, and the capability set corresponding to the S-CSCF2 is determined as the designated capability set.
Step 207, the I-CSCF sends the initial registration request to the S-CSCF.
Step 208, the S-CSCF sends a Multimedia Authentication Request (MAR) to the DRA.
In this embodiment, the MAR is specifically an authentication request Vector (AV).
In this embodiment, the MAR carries the S-CSCF id.
In this embodiment, AV is security data required for authentication.
Step 209, the DRA sends the MAR to the primary HSS, and the MAR carries the S-CSCF identification.
In this embodiment, the MAR carries the S-CSCF identifier, that is, the DRA sends the S-CSCF identifier to the master HSS, indicating that the S-CSCF serves the current UE, and the master HSS stores the S-CSCF identifier in the local database, so as to ensure that the user equipment initiates a re-registration request or refreshes a registration request again to reach the same S-CSCF.
Step 210, the master HSS sends a Multimedia authentication response (MAA) message to the DRA, where the MAA message carries the host name and AV of the master HSS.
Step 211, the DRA sends the MAA message to the S-CSCF.
In this embodiment, the S-CSCF stores the host name of the primary HSS to the local database.
Step 212, the S-CSCF sends 401 an authentication challenge message to the UE, and the 401 authentication challenge message carries AV.

Further, the UE determines whether the network side is valid according to the AV, if so, continues to perform step 213; if not, the process ends.
Step 213, the UE sends a re-registration request to the I-CSCF.
In this embodiment, the sending, by the UE, the re-registration request to the I-CSCF specifically includes: and the UE sends the re-registration request to the SBC, and the SBC sends the re-registration request to the I-CSCF.

Step 217, DRA sends UAA message to I-CSCF.
Step 218, the I-CSCF sends a re-registration request to the S-CSCF.
In this embodiment, the I-CSCF sends the re-registration request to the S-CSCF corresponding to the S-CSCF identifier.
Step 219, the S-CSCF sends the first SAR to the DRA, where the first SAR carries the host name of the active HSS.
In this embodiment, a Destination-Host field (Destination-Host) of the first SAR is a Host name of the primary HSS.
In this embodiment, the primary HSS stores user subscription data.

Step 221, the DRA sends a failure response message to the S-CSCF, where the failure response message carries the host name of the disaster-tolerant HSS.
In this embodiment, the failure response message indicates that the state of the master HSS is abnormal.
In this embodiment, when the DRA detects that the state of the primary HSS is abnormal in the configuration file, the corresponding disaster-tolerant HSS is allocated to take over the primary HSS, and the host name of the disaster-tolerant HSS is encapsulated in the failure response message.
In this embodiment, the disaster-tolerant HSS stores the same user subscription data as the corresponding primary HSS.
Step 222, the S-CSCF sends a second SAR to the DRA, and the second SAR carries the host name of the disaster recovery HSS.
In this embodiment, after receiving the failure response message, the S-CSCF extracts the Host name of the disaster-tolerant HSS from the failure response message, replaces the Host name of the primary HSS in the Destination-Host field of the first SAR with the Host name of the disaster-tolerant HSS, and repackages the Host name into the second SAR.
Step 223, the DRA sends the second SAR to the disaster recovery HSS.
In this embodiment, the DRA sends the second SAR to the corresponding disaster-tolerant HSS according to the host name of the disaster-tolerant HSS.
Step 224, the disaster-tolerant HSS sends the SAA message to the DRA.
In this embodiment, the SAA message carries user subscription data, that is: and the disaster-tolerant HSS sends the user subscription data to the DRA.
Step 225, the DRA sends the SAA message to the S-CSCF.
In this embodiment, the DRA sends the user subscription data to the S-CSCF.
Step 226, the S-CSCF sends a confirmation message to the UE.
In this embodiment, the sending of the confirmation message to the UE by the S-CSCF specifically includes: and the S-CSCF sends the confirmation message to the SBC, and the SBC sends the confirmation message to the UE.
