The first embodiment,

An embodiment of the present invention provides a network information transmission method, applied to a first network device, as shown in fig. 2, including:

step 202: sending a paging message containing network information of the first network to the first terminal device.

In this embodiment, the terminal device can simultaneously access at least two networks, for example, simultaneously access two networks, one being a mobile communication network and a private network, where the private network may be understood as a private network or a non-public network (NPN network) laid out by a local user or an administrator, and only authorized users who can access have a right to access the private network or the non-public network; or, the above method may be also adapted to other scenarios, two different PLMNs; alternatively, one 5GS and the other is EPC; or, two different non-public networks.

The at least two networks share an access network, and the at least two networks share a core network, or do not share a core network. For example, two PLMNs share the same access network; or, the 5GC and the EPC are connected with the same access network; alternatively, two different non-public networks, i.e. NPN networks, are connected to the same access network. Referring to fig. 3, two networks may share one Access Network, that is, a Next Generation (NG) Radio Access Network (RAN) shown in the figure is shared by a PLMN and an NPN, and meanwhile, the two networks may also share the same core Network, that is, a Core Network (CN) shown in the figure is shared by two networks. Referring also to fig. 4, two networks may share one Access Network, that is, a Next Generation (NG) Radio Access Network (RAN) shown in the figure is shared by a PLMN and an NPN, and core networks of the two networks are separated, that is, Core Networks (CN) shown in the figure are a PLMN CN and an NPN CN, respectively.

In this embodiment, the first network device may be an Access and Mobility Management Function (AMF) in a communication network. The third network device may be a Session Management Function (SMF) in the core network.

The network information comprises at least one of the following:

the network identification information, the network name information, the network type and the identification information of the first terminal equipment in the first network.

and receiving a downlink data notification aiming at the first terminal equipment from the first network from the third network equipment.

The third network device may be a core network device in a network where the UE currently acquires data, for example, a Session Management Function (SMF). When the third network device sends data to the first network device, that is, when downlink data for the first terminal device is sent to the first network device, the PDU session information, the network information of the first network, and the connection information may be included. The PDU session information may be a PDU session ID.

Further, the sending the paging message including the network information of the first network to the first terminal device may be sending the paging message including the network information of the first network to the first terminal device through the radio access network RAN.

Specifically, after receiving the paging message, the terminal device also knows which network the paging is received from, or after receiving a communication request sent from a second terminal device in which network, receives a service request sent from the first terminal device through the first network device; further, the service request is transmitted to the corresponding target network based on the network information of the first network included in the service request. For example, the networks that the first terminal device can access currently are the first network and the second network, and based on the paging message, the first terminal device can learn that the paging message is a page from the first network, so that the first network device can be instructed to send the service request to the corresponding first network.

In this embodiment, referring to the flowchart of fig. 5, it is assumed that the first network device is an AMF, the third network device is an SMF, and the second network device is a UPF; the specific process is illustrated as follows:

1. the UPF receives downlink data for the first terminal device sent by the DN, where the downlink data may include network information of the first network, that is, the NPN; that is, the external data network has downlink data to send to the terminal, and sends the downlink data to the first terminal device through the UPF; this external network may be a network from an external server, or other UPF, or any other third party network entity, or other access network;

2a, the UPF sends a downlink data notification to the SMF, optionally, the notification may further include at least one of PDU session information, connection information, and network information;

2b, UPF sends down data notice to SMF, SMF determines at least one of PDU conversation information, connection information and network information;

3. the SMF sends a downlink data notification to the AMF, optionally, the notification may further include at least one of PDU session information, connection information, and network information;

4. the AMF determines network information of the first network based on at least one of PDU session information, connection information and network information of the first network;

5-6, the AMF sends a paging message to the first terminal device via the NG-RAN and includes network information of the first network in the paging message.

Then, the method can further include determining which network the called service belongs to according to the network information in the paging message after the terminal receives the paging message, and initiating a service request in the network.

Therefore, when the information is sent to the first terminal device, the network information including the corresponding first network is added in the paging message, so that the first terminal device can acquire the target network from which the paging message is sent, and when the first terminal device can access at least two networks, the first terminal device can determine the target network to which the data is interacted, and the system processing efficiency is improved.

For example, the networks that the first terminal device can access currently are the first network and the second network, and based on the paging message, the first terminal device can learn that the paging message is a page from the first network, so that the first network device can be instructed to send the service request to the corresponding first network. It should be further understood that, after the first terminal device initiates the service request to the first network, data interaction may be performed between the core network of the first network and the first terminal device through the shared access network, which is not described herein again.

5-6, the AMF sends a paging message to the first terminal device via the NG-RAN and includes network information of the first network in the paging message. After receiving the paging message, the terminal determines which network the called service belongs to according to the network information in the paging message, and initiates a service request in the network.
