Fig. 2 is a first schematic flow chart of an information configuration method according to an embodiment of the present application, and as shown in fig. 2, the information configuration method includes the following steps:

step 201: the first core network determines target network information.

In one embodiment, the first core network sends first RFSP information to the first access network, so that the first access network determines target network information according to the first RFSP information and sends the target network information to the terminal. Here, the first core network acquires the first RFSP information from a subscription server of the terminal; or, the first core network acquires the first RFSP information according to the second configuration information.

Here, the target network information includes at least one of: RAT information and frequency point information.

Step 202: and the first core network determines target core network information according to the target network information.

In the embodiment of the application, if the access network on the target network information is connected with multiple types of core networks or multiple core networks at the same time, the first core network determines the target core network information according to the first configuration information; and the first core network sends the target core network information to a first access network. Here, if the second access network is connected to only one core network, the first core network does not need to configure target core network information to the first access network.

According to the technical scheme of the embodiment of the application, whether the target core network information is matched with the target RAT and/or frequency point information is verified by the core network, specifically, the core network transmits the RFSP information to the access network, and the access network configures the target RAT and/or frequency point information redirected by the terminal to the terminal according to the RFSP information. The core network selects appropriate RFSP information from a subscription server of the terminal or according to local configuration. When a terminal initiates a service and needs to return the terminal to other networks, a core network determines target RAT and/or frequency point information and determines target core network information indicated to an access network according to the core network connected with a target access network corresponding to the target RAT and/or frequency point information. The following can be achieved: 1) if the target access network is connected to multiple core networks or multiple core networks, such as EPC and 5GC, the core network selects the retroversion target core network information according to local configuration and indicates the retroversion target core network information to the access network; 2) and if the target access network is connected with only one core network, the core network does not configure the target core network information for the access network.

Fig. 3 is a second schematic flowchart of an information configuration method according to an embodiment of the present application, and as shown in fig. 3, the information configuration method includes the following steps:

step 301: the first access network receives the target core network information and/or the first RFSP information sent by the first core network.

Specifically, the core network transmits the RFSP information to the access network, and the access network determines to configure the RAT/frequency point redirected by the terminal to the terminal according to the RFSP information. When the terminal initiates a service and needs to fall back to another network (such as a RAT and a frequency point), the core network indicates the target core network information to the access network. The access network determines the RAT/frequency point information of the redirection terminal. Or the access network determines the RAT/frequency point information of the redirection terminal according to the RFSP information sent by the core network.

The target network information in the following embodiments includes at least one of: RAT information and frequency point information.

Step 302: and the first access network determines target network information according to the target core network information and/or the first RFSP information.

The first method is as follows: the first access network determines network information matched with the target core network information and takes the network information as target network information; and the first access network sends the target network information and/or the target core network information to the terminal.

Further, if the first access network does not determine the network information matched with the target core network information, the first access network sends a first notification message to the first core network, where the first notification message is used to indicate that the target core network information is invalid or that the target core network information is not sent to the terminal. Optionally, the first notification message further carries a first cause value, where the first cause value is used to indicate that the first access network does not determine the network information matched with the target core network information.

Specifically, the access network determines target RAT and frequency point information according to target core network information indicated by the core network. And the access network selects the RAT and the frequency point which support the target core network as a redirection RAT and a frequency point and sends the redirection RAT and the frequency point to the terminal, and the information of the target core network is also sent to the terminal. If the access network does not select the RAT and the frequency point supporting the target core network, the access network does not send the target core network information to the terminal, optionally, the access network replies a response message to the core network to indicate that the target core network information is invalid or is not transmitted to the terminal, optionally, the response message carries a reason to indicate that the target RAT and the frequency point information suitable for the target core network are not found.

The second method comprises the following steps: and the first access network determines whether to send the target core network information to the terminal according to the first RFSP information.

Further, if the target network information determined by the first access network according to the first RFSP information matches the target core network information, the first access network sends the target network information and/or the target core network information to the terminal. And if the target network information determined by the first access network according to the first RFSP information is not matched with the target core network information, the first access network sends a first notification message to the first core network, wherein the first notification message is used for indicating that the target core network information fails or the target core network information is not sent to the terminal. Optionally, the first notification message further carries a first cause value, where the first cause value is used to indicate that the first access network does not determine the network information matched with the target core network information.

Specifically, the access network determines whether to transmit the target core network information to the terminal according to the RFSP information. And if the access network can be connected to the target core network according to the target RAT and the frequency point information determined by the RFSP information, the access network sends the target core network information to the terminal. Otherwise, the access network does not send the target core network information to the terminal. Optionally, the access network replies a response message to the core network to indicate that the target core network information is invalid or is not transmitted to the terminal, and optionally, the response message carries a reason indicating that the target RAT and the frequency point information suitable for the target core network are not found.

The third method comprises the following steps: and if the access network on the target network information is connected with multiple types of core networks or multiple core networks at the same time, the first access network sends the target core network information to the terminal.

Further, if the access network on the target network information is not connected to multiple types of core networks or multiple core networks at the same time, the first access network sends a first notification message to the first core network, where the first notification message is used to indicate that the target core network information is invalid or that the target core network information is not sent to the terminal. Optionally, the first notification message further carries a first cause value, where the first cause value is used to indicate that the first access network does not determine the network information matched with the target core network information.

Specifically, if the access network on the target RAT and frequency point is connected to multiple core networks or multiple core networks, such as EPC and 5GC, the access network configures the target core network information to the terminal. Otherwise, the access network does not send the target core network information to the terminal. Optionally, the access network replies a response message to the core network to indicate that the target core network information is invalid or is not transmitted to the terminal, and optionally, the response message carries a reason indicating that the target RAT and the frequency point information suitable for the target core network are not found.

Fig. 4 is a schematic flowchart of a third process of an information configuration method according to an embodiment of the present application, and as shown in fig. 4, the information configuration method includes the following steps:

step 401: and the terminal receives the core network information sent by the first access network.

Step 402: if the terminal does not find a cell which can be connected to the core network in the cell on the first target network information, the terminal determines that the core network information is invalid or ignores the core network information, or determines second target network information matched with the core network information and searches the cell which can be connected to the core network on the second target network information.

Here, the target network information includes at least one of: RAT information and frequency point information.

Here, the core network information includes at least one of: PLMN information, core network identification information, core network type information. Further, the core network type information includes at least one of:

a 5G core network or NR core network, a 4G core network or LTE core network, a 3G core network or UTRAN core network.

In the above scheme, the access layer of the terminal submits the core network information to the non-access layer. Specifically, the method comprises the following steps:

1) the access stratum of the terminal indicates to the non-access stratum when finding a cell that can connect to the core network.

Further, the access stratum of the terminal finds a cell on the first target network information and/or finds a cell on the second target network information to connect to the core network.

2) And the access layer of the terminal indicates the core network information indicated by the network to the non-access layer when receiving the core network information.

In the above scheme, if the access layer of the terminal does not find the cell connected to the core network, the access layer of the terminal indicates that the core network information of the non-access layer is invalid or ignores the core network information.

Specifically, the core network sends the target core network information to the access network, the access network sends the target core network information to the terminal, the terminal searches for and resides in a cell on the redirected RAT and frequency point, and if the terminal does not find a cell which can be connected to the target core network on the target RAT and frequency point, the terminal ignores the target core network information. Or the terminal searches the cells which can be connected to the target core network again to other RAT and frequency points.

In the above technical solution of the embodiment of the present application, whether the access network information of the second access network and the core network information of the second core network are matched refers to: if the access network information of a second access network matches the core network information of the second core network, the second access network supports the second core network, or the second access network can connect to the second core network; and if the access network information of the second access network does not match the core network information of the second core network, the second access network does not support the second core network, or the second access network cannot be connected to the second core network.
