Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a registration method, apparatus, and device for an IP multimedia subsystem.
Background
Voice Over LTE (VOLTE) is a Voice service based on an IP Multimedia Subsystem (IMS), that is, a Voice service based on an IP Multimedia Subsystem. After completing network attachment of Long Term Evolution (LTE) or Evolved Packet Core (EPC), the VOLTE user may initiate registration to the IMS network after establishing data bearer and IMS signaling bearer, and after IMS registration is successful, the user may use VOLTE, and may also implement IMS network roaming. However, whether the user is located in the home network or the visited network, when the user performs IMS registration, the registration needs to be completed in the user's home network.
When a user needs IMS registration in a visiting network, an IMS signaling bearer needs to be established first, and then a registration request is sent to a proxy call session control function (P-CSCF) of the visiting network, wherein the registration request carries a domain name of a user home network. The visiting network P-CSCF can find the inquiry call session control function (I-CSCF) of the user Home network according to the domain name of the user Home network, and inquire the Home Subscriber Server (HSS) of the user through the I-CSCF of the Home network, and determine the service call session control function (S-CSCF) for executing IMS registration for the user, thereby completing the registration process. In the above process, when the P-CSCF of the visited network determines, through the I-CSCF of the home network, the S-CSCF for performing IMS registration for the user, the topology hiding inter-network gateway (THIG) function of the I-CSCF of the home network may be used to hide a network structure inside the home network, thereby ensuring the security of the home network.
At the time of IMS registration of a user, if the user uses an ISIM (IP Multimedia Service Identity Module) card, the home network domain name may be directly read from the ISIM card. However, currently, a large number of VOLTE users use Universal Subscriber Identity Module (USIM) cards, and the USIM cards cannot store the home network domain names thereof, so that the users using the USIM cards complete the attachment of the LTE or EPC network through the temporary public Identity. At this time, if the user wants to perform IMS registration, the visiting network P-CSCF can only obtain all S-CSCF capability sets signed by the user in the home network from the HSS in the user equipment home network through the I-CSCF of the visiting network because the visiting network P-CSCF does not have the domain name of the user home network, and the I-CSCF of the visiting network inquires the self-stored S-CSCF capability set corresponding table according to the S-CSCF capability sets distributed by the HSS, and designates the S-CSCF of a home location for the user to complete the IMS registration.
However, in the above-mentioned IMS registration method by the user of the USIM card, since the IMS registration is not performed by the home network I-CSCF, the gateway function between the topologically hidden networks cannot function, and the I-CSCF of the visited network needs to store data of all S-CSCFs in other networks having roaming agreements with the I-CSCF, which exposes the S-CSCF topology structures of other networks to the visited network, brings potential safety hazards to other networks, and is not favorable for network security.

The destination information is used for indicating a home network domain name query server corresponding to the home network of the user equipment. The service setting proxy gateway prestores user information, including user identity identifiers and the like, for example, route information corresponding to the user identity identifiers, so that after receiving a request message sent by user equipment, the service setting proxy gateway can determine target information corresponding to the request information based on the prestored route information and the user identity identifiers, and then send the request information to the home network domain name query server through the target information.
It should be noted that the destination information may include address information or identification information of a home network domain name query server corresponding to the home network of the user equipment.
And 130, sending a request message including the destination information to the home network domain name query server.

Therefore, before the user equipment carries out IMS registration, the home network domain name is obtained from a home network domain name inquiry server of the home network through the service setting proxy gateway, then the IMS registration process is executed, so that the visiting network P-CSCF determines the S-CSCF which executes the user equipment registration in the home network through the I-CSCF of the home network, the registration process is further completed, the I-CSCF of the visiting network does not need to store the data of the S-CSCF in the home network of the user equipment, the network structure in the home network can be hidden through the gateway function between topology hiding networks in the home network I-CSCF, and the problem of hidden danger brought to the home network safety is avoided.

After the user equipment acquires the home network domain name from the response information of the home network domain name query server, the IMS registration can be executed, and a registration request including the home network domain name is sent to the visiting network P-CSCF, so that the IMS registration is completed.
In the embodiment of the invention, after the user equipment establishes the data bearer with the visiting network where the user equipment is located, the user equipment sends a request message comprising a user identity identifier corresponding to the user equipment to a service setting proxy gateway through the data bearer to request the home network domain name of the home network of the user equipment; and after receiving the home network domain name sent by the service setting proxy gateway, the user equipment executes the registration process of the IP multimedia subsystem based on the home network domain name. Therefore, before the user equipment carries out IMS registration, the home network domain name is obtained from a home network domain name inquiry server of the home network through the service setting proxy gateway, then the IMS registration process is executed, so that the visiting network P-CSCF determines the S-CSCF which executes the user equipment registration in the home network through the I-CSCF of the home network, the registration process is further completed, the I-CSCF of the visiting network does not need to store the data of the S-CSCF in the home network of the user equipment, the network structure in the home network can be hidden through the gateway function between topology hiding networks in the home network I-CSCF, and the problem of hidden danger brought to the home network safety is avoided.

It should be noted that, in the prior art, when the visited network I-CSCF queries the S-CSCF capability set mapping table stored in the visited network I-CSCF according to the S-CSCF capability set allocated by the home network domain name query server, the visited network I-CSCF needs to make data of all the S-CSCFs, so that the amount of data that the I-CSCF of the visited network needs to make is large, and the home network must notify the visited network I-CSCF to perform data adjustment as long as the home network has network entry or network exit adjustment of the S-CSCF, which increases the operation load of the I-CSCF device, and is not favorable for operation and maintenance management and roaming intercommunication of the network. In the embodiment of the invention, the user equipment acquires the domain name of the home network before performing IMS registration, the visiting network P-CSCF can directly discover the I-CSCF of the home network when performing IMS registration, and the registration process is completed through the home network I-CSCF, and the registration process is not required to be executed through the visiting network I-CSCF, so that data of S-CSCF manufactured by the visiting network I-CSCF is not required, and data adjustment is performed when the home network has network entry or network exit adjustment of the S-CSCF, thereby reducing the operation load of the I-CSCF equipment, simplifying the complexity of operation and maintenance management of the network, and facilitating roaming intercommunication.
