Description

Communication method and device

Technical Field

The present application 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. In the process of requesting registration from the SNPN by the terminal device, 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-networking network (ON). For example, the terminal device may request to establish a Protocol Data Unit (PDU) session in the ON, and the subsequent ON may send the network entry information to the terminal device through the PDU session. That is, the terminal may access the ON to acquire the network access information, and then use the network access information to initiate a registration request in the SNPN.

In addition, the ON may separate the terminal device from the ON after transmitting the network access information to the terminal device. Generally, when the PDU session is established, the access and mobility management device in the ON starts a timer, and separates the terminal device from the ON after the timer expires.

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

That is, the application function device may determine that the network access information configuration of the terminal device is completed according to the second notification information from the provisioning server.

As a possible implementation, the second notification information includes the GPSI of the terminal device. For example, after receiving the second notification information, the application function device may determine whether the access and mobility management device subscribes to a network access information configuration completion event of the terminal device identified by the GPSI, and if so, perform the following step S403 a.

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

s401b, the terminal device sends the sixth request information to the user plane device. Correspondingly, the user plane device receives the sixth request message from the terminal device.

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

As a possible implementation, the sixth request message includes address information of the provisioning server in the second network, and is used to indicate that the network access message is requested from the provisioning server identified by the address information.

For example, the sixth information may be carried in at least one data packet, and one or more data packets in the at least one data packet may include address information of the provisioning server in the second network. The address information of the provisioning server in the second network is obtained by the terminal device in the PDU session establishment process, and will be described in detail later, which is not described herein again.

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

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

And the seventh request message is used for requesting the 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 obtained by the user plane device during the PDU session setup procedure.

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

Exemplarily, the first data message of the user plane device in the at least one data message includes the address information of the provisioning server in the second network, and the GPSI of the terminal device is added to the header of the data message to obtain the seventh information; or, the user plane device may add the GPSI of the terminal device to the header of the at least one data packet including the address information of the provisioning server in the second network to obtain the seventh information. The method and the device do not limit the position and the number of the data messages of the GPSI added with the terminal equipment.

S403b, the provisioning server sends the network access information to the user plane device. Accordingly, 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 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 message.

S404b, the user plane device sends the 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 perform the following step S405 b.
