Description

User registration information processing method and device and ePDG equipment
Technical Field
The present invention relates to the field of communications applications, and in particular, to a method and an apparatus for processing user registration information, and an ePDG device.
Background
At present, a WiFi session (VoWiFi) service based on an IP Multimedia Subsystem (IMS) architecture can be implemented by deploying an Evolved Packet Data Gateway (ePDG) network element in a 4G Core network (EPC). The ePDG network element enables the EPC network to have WLAN access capability.
The WLAN Access is a Non-3GPP Access, and a terminal is assumed to be in an "Untruded Non-3GPP IP Access", namely a WiFi wireless network. The terminal accesses the ePDG network element through WiFi so as to be attached to the EPC network, and meanwhile, relevant configuration information such as an IP address, a domain name system DNS, a proxy call session control function PCSCF address and the like is acquired. Then, the registration of the IMS network is completed by a Session Initiation Protocol (SIP) message established with the EPC network, so as to finally implement IMS voice and other IMS service functions.
Wherein, the interface between the terminal and the ePDG is an SWu interface, and the secure encrypted connection based on IKEv2 is established. An S2b interface is between the ePDG and a PDN Gateway (PGW), and a GPRS Tunneling Protocol (GTP) session is established through the interface. The PGW distributes an EPC network terminal address, DNS information and a P-CSCF address for the terminal, and the information is issued to the terminal through the ePDG. The terminal sends a SIP register message to the SBC/P-CSCF, and the UDP port of the message is a well-known port 5060. After the IMS registration is completed, the terminal can perform IMS services such as VoWiFi and the like.
In the existing VoWiFi registration process, the PGW only issues the SBC/P-CSCF address to the terminal, and does not include the port number, so the terminal generally uses the default known port number 5060 when registering with the IMS.
However, currently, an actual Session Border Controller (SBC) product generally has a function of being capable of allocating an SIP registration port, and is capable of using other port numbers for registration, which are not necessarily 5060, so that on one hand, networking is more flexible, and on the other hand, some specific personalized product functions, such as distinguishing a network element role according to the port number, deciding a terminal access type (LTE access or WiFi access), and other personalized functions, can be implemented through the terminal accessed port number SBC.
For example, one scenario for the terminal access type is that the terminal may access the EPC network through Long Term Evolution (LTE), and may also access the EPC network through WiFi. If the SIP registration message sent by the terminal does not carry the access type information, or the carried access type information is inaccurate, the IMS network cannot determine the actual access type of the terminal. No matter the LTE access or the WiFi access is carried out, the IP address is allocated to the terminal and the SBC/P-CSCF address is issued by the anchored PGW network element. Although the PGW itself can distinguish the access type of the terminal, the PGW does not have a standard interface to directly notify the SBC/P-CSCF network element. In this case, therefore, the IMS network cannot determine its access type when receiving the SIP register message from the terminal, and particularly, the SBC network element cannot use other personalized product functions brought by differentiating different port numbers. In addition, if other port numbers are manually configured on the terminal, the terminal is too complicated and difficult to understand for a non-professional ordinary mobile phone user, and obviously, the configuration is not reasonable.

Step 12: adding SBC/P-CSCF port number information in the IMS network configuration information to obtain an IMS registration message.
Specifically, the ePDG first obtains SBC/P-CSCF port number information configured for the terminal to be registered, and then obtains an IMS registration message by carrying the SBC/P-CSCF port number information in a private attribute of IMS network configuration information, where the private attribute is an attribute whose value defined in RFC7296 is greater than 16384. The ePDG may configure the port number information of the SBC/P-CSCF on the local device, or may obtain the port number information of the SBC/P-CSCF from an external network element, for example, obtain the port number information of the SBC/P-CSCF from the PGW when establishing the GTP session.
Step 13: and sending the IMS registration message to a terminal to be registered, and indicating the terminal to be registered to perform IMS registration according to the SBC/P-CSCF port number information and the SBC/P-CSCF address.
In the specific embodiment of the invention, after receiving the IMS registration information carrying the SBC/P-CSCF port number information and the SBC/P-CSCF address, the terminal sends an SIP registration message to the SBC/P-CSCF, where a User Datagram Protocol (UDP) port is an SBC/P-CSCF port number issued by the ePDG, and the SBC/P-CSCF performs subsequent processing after receiving the registration message, thereby completing the registration of the terminal to be registered.
According to the technical scheme of the embodiment of the invention, the IMS network configuration information of the terminal to be registered is obtained, wherein the IMS network configuration information comprises an SBC/P-CSCF address allocated for the terminal to be registered; adding SBC/P-CSCF port number information in the IMS network configuration information to obtain an IMS registration message; and sending the IMS registration message to the terminal to be registered, and indicating the terminal to be registered to perform IMS registration according to the SBC/P-CSCF port number information and the SBC/P-CSCF address. In the embodiment of the invention, the terminal can carry out IMS registration according to the SBC/P-CSCF port number information and the SBC/P-CSCF address by adding the SBC/P-CSCF port number information in the IMS network configuration information, so that the SBC can flexibly configure the port without being fixed on a certain port, thereby being more flexible in networking.
Further, the step 11 specifically includes: carrying out authentication processing on the terminal to be registered;
after the authentication of the terminal to be registered is passed, sending a session request message for establishing a GIP session to a PDN gateway PGW; and acquiring a session response message returned by the PGW according to the session request message, wherein the session response message carries the IMS network configuration information. Specifically, the authentication processing is performed on the terminal to be registered through a 3GPP AAA server.
According to the method for processing the user registration information, the terminal performs IMS registration by using the port number of the SBC/P-CSCF issued by the EPC network in the VoWiFi scene, meanwhile, manual configuration on the terminal is not needed, so that the SBC can flexibly configure the port without being fixed on a 5060 port, the networking is more flexible, and the SBC/P-CSCF network element can also enable the related personalized function of the port.
The following describes the implementation of the embodiment of the present invention.
As shown in fig. 2, the method for processing user registration information according to the embodiment of the present invention includes:
step 21: and the terminal UE establishes an IKE tunnel with the eDPG.
Step 22: the terminal authenticates between the ePDG and the 3GPP AAA server, and the network side performs authentication and authorization processing.
Step 23: the ePDG sends a message of a session establishment request to the PGW to request the establishment of a GTP session.
Step 24: the PGW performs IP connection access network IP-CAN session processing, including terminal IP address allocation, processing of interaction with a policy and charging rule function PCRF, and the like.
Step 25: the PGW informs the 3GPP AAA server to update the PGW address information.
Step 26: the PGW returns a session establishment response message to the ePDG, wherein the session establishment response message comprises the IP address allocated to the terminal and the SBC/P-CSCF address of the IMS.
Step 27: and the terminal establishes an Internet protocol security IPSec tunnel with the ePDG.
Step 28: the ePDG returns an IKEv2 response message to the terminal, carries information such as the IP address of the terminal and the SBC/P-CSCF address of the IMS issued by the PGW, and carries the SBC/P-CSCF port number in the configuration attribute CFG _ REPLY through the private attribute type.
Step 29: and the terminal sends the SIP registration message to the SBC/P-CSCF, and the UDP port is the port number of the SBC/P-CSCF sent by the ePDG. Wherein, the message is forwarded to IMS network through IPsec tunnel and GTP tunnel, SBC/P-CSCF carries on the subsequent processing after receiving the registration message.
The method for processing the user registration information adds the SBC/P-CSCF port number information in the IMS network configuration information, so that the terminal can carry out IMS registration according to the SBC/P-CSCF port number information and the SBC/P-CSCF address, and further the SBC can flexibly configure the port without being fixed to a certain port, thereby being more flexible in networking.
