Local network connection method, apparatus, and system

1. A local network connection method, applied to a control plane node, the method comprising:

receiving a location area identity from an access node, the location area identity indicating a location area in which a user equipment is located;

obtaining local network subscription information of the user equipment, the local network subscription information indicating a subscribed local network of the user equipment;

determining at least one local network identity based on the location area identity and based on the local network subscription information, and sending the at least one local network identity to the user equipment;

receiving a connection establishment request from the user equipment, the connection establishment request carrying a first local network identity, wherein the first local network identity is within the at least one local network identity; and

establishing a connection between the user equipment and a first local network based on the first local network identity.

2. The method according to claim 1 , wherein the access request comprises a location area update request or an attach request, the location area update request is sent by the user equipment when the location area of the user equipment changes, and the attach request is sent by the user equipment when the user equipment is enabled.

3. The method according to claim 1 , wherein before the establishing the connection between the user equipment and the first local network based on the first local network identity, the method further comprises:

determining whether the at least one local network identity comprises the first local network identity; and

establishing the connection between the user equipment and the first local network based on the first local network identity when the at least one local network identity comprises the first local network identity.

4. The method according to claim 1 , wherein the local network identity is an access point name corresponding to a local network, corresponding to a network name of the local network, or corresponding to an enterprise name of the local network.

5. The method according to claim 1 , wherein the subscribed local network comprises one or more subscribed local networks.

6. A local network connection apparatus, comprising:

a non-transitory computer readable medium storing computer readable instructions; and

a processor in communication with the computer readable medium, wherein the processor executes the instructions to:

receive a location area identity from an access node, location area identity indicating a location area in which a user equipment is currently located;

obtaining local network subscription information of the user equipment, the local network subscription information indicating a subscribed local network of the user equipment;

determine at least one local network identity based on the location area identity and based on the local network subscription information, and send the at least one local network identity to the user equipment;

receive a connection establishment request sent by the user equipment, the connection establishment request carrying a first local network identity, wherein the first local network identity is within the at least one local network identity; and

establish a connection between the user equipment and a first local network based on the first local network identity.

7. The apparatus according to claim 6 , wherein the access request comprises a location area update request or an attach request, the location area update request is sent by the user equipment when the location area of the user equipment changes, and the attach request is sent by the user equipment when the user equipment is enabled.

8. The apparatus according to claim 6 , wherein the subscribed local network comprises one or more subscribed local networks.

9. A local network connection system, the system comprising:

a control plane node;

an access node in communication with the control plane node, the access node configured to:

send a location area identity to the control plane node upon receiving the access request from the user equipment, the location area identity indicating a location area in which the user equipment is located;

the control plane node is configured to:

receive the location area identity;

obtain local network subscription information of the user equipment, the local network subscription information indicating a subscribed local network of the user equipment;

determine at least one local network identity based on the location area identity and based on the local network subscription information;

send the at least one local network identity to the user equipment;

receive a connection establishment request from the user equipment, the connection establishment request carrying a first local network identity, wherein the first local network identity is within the at least one local network identity; and

establish a connection between the user equipment and a first local network based on the first local network identity.

10. The system according to claim 9 , wherein the subscribed local network comprises one or more subscribed local networks.

11. A non-transitory computer-readable medium storing computer instructions that when executed by one or more processors, cause the one or more processors to perform the steps of:

receiving a location area identity from an access node, wherein the location area identity is from the access node and indicates a location area in which a user equipment is located;

obtaining local network subscription information of the user equipment, the local network subscription information indicates subscribed local network of the user equipment;

determining at least one local network identity based on the location area identity and the local network subscription information, and sending the at least one local network identity to the user equipment;

receiving a connection establishment request from the user equipment, wherein the connection establishment request carries a first local network identity, wherein the first local network identity is within the at least one local network identity; and

establishing a connection between the user equipment and a first local network based on the first local network identity.
