Fig. 2 is a flowchart of another exception handling method according to an embodiment of the present invention, and as shown in fig. 2, the method includes:
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 specifically requests multiple capability sets corresponding to multiple S-CSCFs.
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-CSCF (S-CSCF 1, S-CSCF2 and S-CSCF 3) can be selected, and the capability sets corresponding to the S-CSCF1 are 1, 2 and 3; the corresponding capability set of the S-CSCF2 is 1, 2, 3 and 100; the corresponding capability sets of the S-CSCF3 are 1, 2, 3 and 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 corresponding capability sets of the S-CSCF1 are 1, 2 and 3; the corresponding capability set of the S-CSCF2 is 1, 2, 3 and 100; and if the capability set corresponding to the S-CSCF3 is 1, 2, 3 and 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 an appointed 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.
And step 209, the DRA sends the MAR to the main 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 first host name list and the AV.
In this embodiment, the master HSS is configured with a master HSS configuration file, and the host name of the master HSS and the host name of the disaster-tolerant HSS corresponding to the master HSS are recorded in the master HSS configuration file. At this time, the preset first priority order is that the priority of the master HSS is higher than that of the disaster-tolerant HSS, and a first host name list is generated according to the first priority order, the host name of the master HSS and the host name of the disaster-tolerant HSS. The first host name list is: host names of main HSS and disaster-tolerant HSS. Namely: the host names of the main HSS with high priority are ranked in the front, and the host names of the disaster-tolerant HSS with low priority are ranked in the back.
Step 211, the DRA sends the MAA message to the S-CSCF.
In this embodiment, the S-CSCF stores the first host name list in 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.
In this embodiment, the sending 401 of the authentication challenge message to the UE by the S-CSCF specifically includes: and the S-CSCF sends the 401 authentication challenge message to the I-CSCF, the I-CSCF sends the 401 authentication challenge message to the SBC, and finally the SBC sends the 401 authentication challenge message to the UE.
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 214, the I-CSCF sends the UAR to the DRA.
In this embodiment, the UAR is specifically a request S-CSCF identifier.
And step 215, sending the UAR to the master HSS by the DRA.
And step 216, the master HSS sends UAA information to the DRA, wherein the UAA information carries the S-CSCF identification.
Step 217, DRA sends UAA message to I-CSCF.
Step 218, the I-CSCF sends the 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.
And step 219, the S-CSCF sends the SAR to the DRA, and the SAR carries the first host name list.
In this embodiment, destination-Host fields of the SAR are a Host name of the primary HSS and a Host name of the disaster-tolerant HSS, that is, contents of the first Host name list.
In this embodiment, the primary HSS stores user subscription data.
Step 220, the DRA detects that the state of the active HSS is abnormal according to the first host name list.
In this embodiment, the DRA detects the state of the active HSS according to the host name of the active HSS, where the state of the active HSS includes: normal or abnormal. If the state of the master HSS is detected to be normal, the DRA sends the SAR to the master HSS, receives a Server Assignment Answer (SAA) message sent by the master HSS, the SAA message carries the host name and the user subscription data of the master HSS, sends the SAA message to the S-CSCF, and continues to execute step 226; if the state of the primary HSS is detected to be abnormal, step 221 is continuously performed.
And step 221, the DRA sends the SAR to a disaster-tolerant HSS according to the DRA configuration file.
In this embodiment, the DRA is configured with a DRA configuration file, and the DRA configuration file records a primary HSS and a disaster-tolerant HSS corresponding to the primary HSS; and the DRA sends the SAR to a disaster-tolerant HSS corresponding to the main HSS according to the DRA configuration file.
In this embodiment, the disaster tolerant HSS determines whether the Destination-Host field content in the SAR includes the Host name of the disaster tolerant HSS, if yes, step 223 is executed continuously; if not, the process ends.
In this embodiment, if the disaster-tolerant HSS determines that the SAR carries the host name of the disaster-tolerant HSS, the disaster-tolerant HSS takes over the primary HSS.
In this embodiment, the disaster-tolerant HSS stores the same user subscription data as the corresponding primary HSS.
Step 223, the disaster tolerance HSS sends SAA message to the DRA, where the SAA message carries the host name of the disaster tolerance HSS.
In this embodiment, an Origin-Host (Origin-Host) field of the SAA message is a Host name of the disaster-tolerant HSS, indicating that the SAA message is sent by the disaster-tolerant HSS.
In this embodiment, the SAA message carries user subscription data, that is: and the disaster tolerance HSS sends the user subscription data to the DRA.
Step 224, 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 225, the S-CSCF generates a second list of host names according to the SAA message.
In this embodiment, the S-CSCF detects whether the host name of the primary HSS or the host name of the disaster tolerant HSS is carried in the SAA message. If the host name of the main HSS is detected to be carried, the first host name list in the S-CSCF local database is kept unchanged; if the carried host name of the disaster-tolerant HSS is detected, the S-CSCF adjusts the first host name list, the preset second priority order is that the priority of the disaster-tolerant HSS is higher than that of the main HSS, and the second host name list is generated according to the second priority order, the host name of the main HSS and the host name of the disaster-tolerant HSS. The second host name list is: host names of disaster-tolerant HSS and host names of main HSS.
Further, the S-CSCF saves the second list of host names to a local database.
Further, when the UE sends a refresh registration request to the I-CSCF again, the I-CSCF sends UAR to the main HSS and receives UAA sent by the main HSS; the I-CSCF sends a refresh registration request to the S-CSCF; the S-CSCF sends the SAR to the DRA, the SAR carries a second Host name list at the moment, namely the Destination-Host field of the SAR is the Host name of the disaster-tolerant HSS and the Host name of the main HSS at the moment; the DRA detects whether the state of the master HSS is abnormal or not according to the master name of the master HSS in the second master name list, if so, the SAR is sent to the disaster-tolerant HSS according to the DRA configuration file configured by the DRA, and the steps 221 to 226 are continuously executed; if not, the SAR is sent to the master HSS, the SAA message sent by the master HSS is received, the SAA message is sent to the S-CSCF, and the step 226 is continuously executed.
Step 226, the S-CSCF sends an acknowledgement 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.
In the scheme of the embodiment of the invention, a multimedia authentication response request sent by a service call session control function is received, wherein the multimedia authentication response request is sent by the service call session control function through a routing agent node; generating a first host name list according to the host name of the host, the host name of the corresponding disaster recovery home location register and a preset first priority order; and sending a multimedia authentication response message to the routing agent node, wherein the multimedia authentication response message carries the first host name list so that the routing agent node sends the multimedia authentication response message to the service call session control function, so that the user equipment can continue to execute the initial registration process or the refresh registration process even if the main home location register fails in the initial registration process or the refresh registration process, and the success rate of the initial registration and the refresh registration is improved.
