Step 402: Determine whether the terminal device is authorized to access the target first-type network based on the request message.

In this embodiment, the second network device may be understood as a core network device in a network where the current terminal device is located.

This embodiment is different from the first and second embodiments in that in this embodiment, the core network device on the network side is used to control whether the terminal device can access the first type network.

The two cases are described below:

Case one,

Receive the measurement report of the terminal device through the access network device of the source network, that is, the first network device. The measurement report may include: information about the target first-type network; for example, the cell identifier of the first-type network At least one of information, network type information, and network identification information;

After receiving the measurement report, the first network device sends request information to the second network device, that is, the core network device in the source network (specifically, this may be handover request information); in the request information, Can carry information of target first-class networks;

After receiving the handover request information of the terminal device sent by the first network device, the second network device verifies whether the terminal device is authorized to access the target first-type network.

Before authentication, authorization information of the terminal device on the target first-type network may also be obtained.

That is, authorization information corresponding to the terminal device is stored in the target first-type network, and according to the network type and / or network identifier in the authorization information, it may further include a RAT, etc. The first type of network is compared with the network type and / or network identification and / or RAT information, and when matched, it is determined that the terminal device is allowed to access or switch to the target first type network; otherwise, all The terminal device accesses or switches to the target first-type network.

Further, in this case, since the terminal device needs to be switched to the target first-type network, the second network device may also send a handover request of the terminal device to the core network of the target network.

For example, see Figure 5,

1. The terminal sends a measurement report, which carries the target network information, such as cell identification information, network type information, and network identification information.

2. The source access network sends a handover request message to the source core network, which carries the target network information;

3. The source core network verifies whether the terminal is authorized to access the target network.

4. The source core network obtains the contract information of the terminal in the target network or the network attribute information to which the terminal belongs. If the terminal contract information allows the terminal to access or switch to this target network, the source core network initiates a handover request to the target core network; Otherwise, the source core network rejects the handover request. Here, when the request is rejected, the reason for the rejection can also be sent to the terminal device. Specifically, it can be a rejection code. The rejection code is pre-negotiated and saved on the terminal and the network side.
