As a possible implementation manner, the terminal accesses the AP device of the wifi network, and after receiving the operation of the user requesting data, generates a data request and sends the data request to the AP device.

In some embodiments, the identity of the terminal may be a media access control (medium access control, MAC) address of the terminal, and/or a user name and password of the terminal.

The user name and the password of the terminal can be preset when the terminal accesses the AP.

Correspondingly, the AP equipment receives the data request of the terminal.

It should be noted that the first interface protocol may be preset by an operator of the communication system. For example, the first interface protocol may be a wireless access point control and provisioning (controlling and provisioning of wireless access point, CAPWAP) protocol.

Correspondingly, the UPF device receives an address allocation request sent by the AP device based on the first interface protocol.

S204, the UPF equipment responds to the address allocation request, and allocates an address for the terminal based on a Dynamic Host Configuration Protocol (DHCP) module included in the UPF equipment.

As a possible implementation manner, the UPF device obtains the identifier of the terminal from the address allocation request, determines the quality of service (quality of service, qoS) information allocated to the terminal according to the identifier of the terminal, and allocates an address to the terminal through a dynamic host configuration protocol (dynamic host configuration protocol, DHCP) module included in the UPF device.

The address allocated to the terminal may be an internet protocol (Internet Protocol, IP) address.

In this step, the implementation manner of the DHCP module for allocating an address to the terminal may refer to the prior art, and will not be described herein.

The second authentication request is used for requesting the AMF equipment to authenticate the terminal.

As a possible implementation manner, the AP device obtains the identifier of the terminal from the first authentication request, and generates the second authentication request according to the identifier of the terminal.

S303, the AP equipment sends a second authentication request to the mobile management function AMF equipment.

As a possible implementation manner, the AP device sends a second authentication request to the AMF device through a preset second interface protocol.

It should be noted that the second interface protocol may be preset by an operator of the communication system. For example, the second interface protocol may be the CAPWAP protocol.

Accordingly, the AMF device receives the second interface protocol sent by the AP device based on the second interface protocol.

The second authentication request is for requesting authentication of the terminal, the second authentication request including an identification of the terminal.

S304, the AMF equipment authenticates the terminal based on the identification of the terminal.

As a possible implementation manner, the AMF device obtains the identifier of the terminal from the second authentication request, and authenticates the terminal according to the identifier of the terminal.

S402, the AMF device sends a third authentication request to the AUSF device of the authentication server function.

Correspondingly, the AUSF device receives a third authentication request sent by the AMF device.

S403, the AUSF equipment acquires authentication information corresponding to the terminal from the Unified Data Management (UDM) equipment based on the identification of the terminal.

The authentication information is used to indicate a pre-stored media access control MAC address of the terminal and/or a user name and password of the terminal.

As a possible implementation manner, the AUSF device obtains the identifier of the terminal from the third authentication request, and sends a fourth authentication request to the UDM device to obtain authentication information corresponding to the terminal.

It should be noted that authentication information of the terminal is stored in the UDM in advance.

Correspondingly, the UDM device responds to the fourth authentication request, acquires authentication information corresponding to the terminal, and sends the authentication information corresponding to the terminal to the AUSF device.

S404, the AUSF equipment authenticates the terminal based on the authentication information.

As a possible implementation manner, the AUSF device determines that the terminal passes authentication if it is determined that the identifier of the terminal matches authentication information corresponding to the terminal.

S405, the AUSF device sends an authentication pass message to the AMF device.

Wherein the indication authentication pass message is used for indicating that the terminal has passed authentication of the 5GC.

Correspondingly, the AMF device receives an indication authentication passing message sent by the AUSF device.

In one design, as shown in fig. 4, the communication method provided in the embodiment of the present invention further includes the following S406, because QoS information of the terminal is pre-stored in the UPF device.

S406, the AMF device sends an indication configuration message to the session management function SMF device under the condition that the terminal passes the authentication.

Wherein the indication configuration message comprises an identification of the terminal. The indication configuration message is used for indicating the SMF device to configure the quality of service QoS information for the user plane function UPF device based on the identification of the terminal.

Accordingly, after receiving the indication configuration message, the SMF device performs a rule query to the PCF device. Further, the PCF device feeds back a rule query response to the SMF device.

The PCF device feeds back the rule query response to the SMF device, i.e. configures the terminal with the corresponding QoS information.

Further, the SMF device issues QoS information of the terminal to the UPF device.

In one design, because the AMF device and the AP device in the 5GC in the current network do not establish a data transmission tunnel, in order to implement the data transmission tunnel between the 5GC and the wifi network, as shown in fig. 5, the communication method provided in the embodiment of the present invention specifically further includes the following S501-S503.

S501, the AP equipment sends a discovery request to the mobile management function AMF equipment.

Wherein the discovery request is for requesting a communication connection to be established with the AMF device.

As one possible implementation, the AP device generates a discovery request and sends the discovery request to the AMF device after startup.

It will be appreciated that the discovery request is used to determine if the AMF device for 5GC is online.

Accordingly, the AMF device receives the discovery request sent by the AP device.

S502, the AMF device generates a discovery response message and configuration information.

The discovery response message is used for indicating that the AMF equipment is online, and the configuration information is used for indicating the working frequency band and the power of the AP equipment.

S503, the AMF device sends a discovery response message and configuration information to the AP device.

Correspondingly, the AP equipment receives the discovery response message and the configuration information sent by the AMF equipment, and works according to the responded working frequency band and power.

It can be understood that after the AP device receives the discovery response message sent by the AMF device, a data transmission tunnel between the AP device and the AMF device is established, that is, fusion deployment of the 5GC and wifi network is achieved.

The embodiment of the invention provides a communication method and equipment, which can realize the fusion deployment of a wifi network and a 5GC through the interaction of signaling between an AP (access point) device and a UPF (unified power flow) device, and can expand the access capability of the wifi network while supporting the original 5GC, so that compared with the prior art, the method and equipment have the advantages that the terminal is not required to be transformed, and the fusion deployment of the wifi network and the 5GC can be better realized
