Description

Communication method and device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a communication method and apparatus.

Background

An independent non-public network (SNPN) is a communication network architecture for private network scenarios. During the process that the terminal device requests registration with the SNPN, network access information, such as identification information, authentication information, etc., may be provided to the SNPN.

The network access information may be acquired through an ON-board network (ON). Illustratively, the terminal device may request that a protocol data unit (protocol data unit, PDU) session be established in the ON, through which the subsequent ON may send the network entry information to the terminal device. That is, the terminal may first access the ON to obtain the network access information, and then use the network access information to initiate the registration request in the SNPN.

In addition, after the ON transmits the network access information to the terminal device, the terminal device may be separated from the ON. Typically, at the time of PDU session establishment described above, the access and mobility management device in ON starts a timer, which after expiration separates the terminal device from ON.

However, if the timer is short, it may be separated when the terminal device has not successfully acquired the network access information; if the timer is long, the terminal device may still keep connection with the ON after successfully acquiring the network access information, thereby resulting in waste of network resources of the ON.

s401a, the access and mobility management device sends first request information to the application function device. Accordingly, the application function device receives the first request information from the access and mobility management device.

Illustratively, the network access information of the terminal device mainly includes identification information, authentication information, and the like of the terminal device.

Based on the scheme, when the access and mobility management equipment sends first request information to the application function equipment, the terminal equipment is identified by carrying GPSI in the first request information so as to indicate a network access information configuration completion event of the terminal equipment identified by the GPSI, and when the terminal equipment is indicated to the application function equipment, the external application side can be prevented from exposing identification information such as SUCI or SUPI of the terminal equipment.

In some possible implementations, the first request information may also be referred to as terminal device network access information issuing a completion event subscription request. Of course, other names are possible, and this application is not limited thereto.

After S401a, the terminal device may request the network access information from the provisioning server, and in response to the request of the terminal device, the provisioning server may issue the network access information to the terminal device through the user plane, and after the terminal device successfully receives the network access information, the terminal device may send a response to the provisioning server to indicate that the network access information is received. In this process, the application function device may determine that the configuration of the network access information of the terminal device is completed, and thus send a notification of completion of the configuration of the network access information of the terminal device to the access and mobility management device, that is, perform the following steps S402a and S403a:

After receiving the second notification information, the application function device may determine whether the access and mobility management device subscribes to the network access information configuration completion event of the terminal device identified by the GPSI, and if so, execute step S403a described below.

In some possible implementations, the second notification information may also be referred to as an access information configuration completion notification. Of course, other names are possible, and this application is not limited thereto.

S401b, the terminal device sends sixth request information to the user plane device. Correspondingly, the user plane device receives the sixth request information from the terminal device.

The sixth request information is used for requesting the provisioning server for network access information of the terminal equipment.

As a possible implementation, the sixth request information includes address information of the provisioning server in the second network, for indicating that the provisioning server identified by the address information requests the network access information.

Illustratively, the sixth information may be carried in at least one data message, one or more of which may include address information of the provisioning server in the second network. The address information of the provisioning server in the second network is acquired by the terminal device during the PDU session establishment procedure, which will be described in detail later, and will not be described here.

In some possible implementations, the sixth request information may also be referred to as the network access information request information, and of course, there may be other names, which is not limited in this application.

S402b, the user plane device sends seventh request information to the provisioning server. Accordingly, the provisioning server receives the seventh request information from the user plane device.

The seventh request information is used for requesting network access information of the terminal equipment.

As a possible implementation, the seventh request information includes a GPSI of the terminal device. The GPSI of the terminal device may be acquired by the user plane device during the PDU session establishment procedure.

As a possible implementation, the ue may add the GPSI of the terminal device to a header of one or more data packets in the at least one data packet carrying the sixth request information, to obtain seventh information.

The user plane device adds the GPSI of the terminal device to the header of the data packet including the address information of the provisioning server in the second network, so as to obtain seventh information; alternatively, the ue may add the GPSI of the terminal device to the at least one header of the data packet including the address information of the provisioning server in the second network to obtain the seventh information. The position and the number of the GPSI data messages added to the terminal equipment are not limited.

S403b, the provisioning server sends networking information to the user plane device. Correspondingly, the user plane device receives the network access information from the provisioning server.

As a possible implementation, the provisioning server sends a network access information delivery message to the user plane device, where the network access information delivery message includes the network access information.

As a possible implementation, the provisioning server may determine the network access information of the terminal device according to the GPSI in the seventh request information.

S404b, the user plane device sends network access information to the terminal device. Correspondingly, the terminal equipment receives the network access information from the user plane equipment.

Further, after receiving the network access information, the terminal device may further execute step S405b described below.
