[0051] refer to figure 2 , the first embodiment includes the following steps:
[0052] Step 201, pre-setting a user registration status priority list on the HSS.
[0053] In the priority table, for the four user registration states REGISTERED, REGISTERED_WITH_UNREG_SERVICE, NOT_REGISTERED, and AUTHENTICATION_PENDING, the order of priority from high to low can be set as required. The first embodiment uses Table 1 as an example to illustrate the user registration state priority setting.
[0054] In Table 1, the order of priority from high to low is: AUTHENTICATION_PENDING>REGISTERED>REGISTERED_WITH_UNREG_SERVIC>REGISTERED_WITH_UNREG_SERVICE>NOT_REGISTERED, where ">" indicates that the priority of the previous user registration status is higher than that of the latter user registration status.

[0068] Different from the IMPU carried in the UDR message in the first embodiment, in the second embodiment, the UDR message carries the IMPI, and the HSS performs corresponding processing according to the UDR message carrying the IMPI, and returns an appropriate user registration status to the AS.
[0069] refer to Figure 4 , the second embodiment includes the following steps:
[0070] Step 401, pre-setting a user registration status priority table on the HSS.
[0071] The second embodiment still uses Table 1 to illustrate the priority of user registration status. In Table 1, the order of priority from high to low is: AUTHENTICATION_PENDING>REGISTERED>REGISTERED_WITH_UNREG_SERVIC>REGISTERED_WITH_UNREG_SERVICE>NOT_REGISTERED, where ">" indicates that the priority of the previous user registration status is higher than that of the latter user registration status.

Abstract
The invention discloses a method for responding to a user registration state request. The method includes the following steps: setting a user registration state priority table for saving user registration state priority in the HSS in advance; the HSS according to the first user identifier and Pre-saved correspondence between the first user ID and the second user ID and the user registration status, obtaining all user registration statuses corresponding to the first user ID, and obtaining the acquired user registration status according to the user registration status priority table The user registration status with the highest priority in the status, and send the user registration status with the highest priority to the AS through a UDA message. The invention also provides a system for responding to user registration status requests. When the first user ID corresponds to a plurality of second user IDs, the invention can correctly respond to the UDR message and return the appropriate user registration status to the AS, thereby making up for the deficiency of the existing protocol.
Description
technical field [0001] The invention relates to the field of IP multimedia service sub-network (IMS), in particular to a method and system for responding to user registration status requests. Background technique [0002] In the IMS domain, a piece of subscription data (IMS Subscription) contains a public user identity (IMS Public User Identity, IMPU), a private user identity (IMS Private UserIdentity, IMPI) and a mobile station International Integrated Services Digital Network (ISDN) number ( MSISDN). figure 1 Shown is the relationship between IMS domain user IDs. There are two IMPIs in the IMS Subscription in the figure: IMPI-1 and IMPI-2, and IMPI-1 is associated with IMPU-1 and IMPU-2, and IMPI-2 is associated with IMPU-2 is associated with IMPU-3, IMPU-1 is associated with Service Profile-1, and IMPU-2 and IMPU-3 are associated with Service Profile-2. From figure 1 It can be seen that there are multiple IMPIs in each IMSSubscription, and there are also situations whe...
