S403, the network device determines the position change of the terminal device according to the current position information.

Optionally, the location change of the terminal device may include: the terminal equipment moves to a service area of a first data network; the terminal device moves out of the service area of the first data network; the terminal equipment returns to the service area of the first data network within a preset time length after being moved out of the service area of the first data network; the terminal device does not return to the service area of the first data network within a preset time after moving out of the service area of the first data network.

For example, the first Data Network in the embodiment of the present invention may be a Local Access Data Network (LADN) that is closer to the terminal device.

For example, as shown in fig. 5, the service area of the LADN is area 1. When the terminal device 01 moves to the position 1, reporting current position information to the network device 02, and determining that the terminal device 01 moves to the area 1 by the network device 02 according to the current position information reported by the terminal device 01; when the terminal device 01 moves to the position 2, the current position information is reported to the network device 02, and the network device 02 determines that the terminal device 01 moves out of the area 1 according to the current position information reported by the terminal device 01.

S404, the network device executes any one of the following S404a-404d according to the position change of the terminal device:

s404a, if the terminal device moves to the service area of the first data network, the network device performs a PDN connection for the first data network.

When the network equipment determines that the terminal equipment moves to a service area of a first data network and receives a service request sent by the terminal equipment, the network equipment performs PDN connection of the first data network, namely, establishes a PDN session between a PDN user plane of the first data network and the PDN of the first data network.

Illustratively, the network device determines that the terminal device has moved to a service area of the first data network. After receiving a service request sent by a terminal device, an AMF of a network device sends a first data network PDN connection request (namely a first data network PDN user plane creation request and a first data network PDN session creation request) to the SMF; the SMF sends a first data network PDN connection request to the UPF; the UPF creates a first data network PDN user plane and a first data network PDN session according to the first data network PDN connection request, and sends a first data network PDN connection response to the AMF through the SMF; and after receiving the PDN connection response of the first data network, the AMF sends a context establishment request to the RAN, establishes a radio bearer with the terminal equipment and completes the connection process of the PDN of the first data network.

In the embodiment of the present invention, when the terminal device moves to the service area of the first data network, the network device may perform PDN connection of the first data network. Because the terminal device is located in the service area of the first data network, that is, when the terminal device is located near the network device, the network device can use the MEC resource of the first data network to perform service transmission with the terminal device, thereby reducing the end-to-end delay and the load of the transmission network, realizing efficient service interaction, and improving the service experience of the user.

S404b, if the terminal device moves out of the service area of the first data network, the network device deletes the PDN user plane of the first data network.

And when the network equipment determines that the terminal equipment moves out of the service area of the first data network, the network equipment deletes the PDN user plane of the first data network.

For example, when the AMF of the network device receives current location information sent by the terminal device (the current location information is used to represent that the terminal device moves out of the service area of the first data network), the current location information is sent to the SMF; after receiving the current position information, the SMF determines that the terminal equipment moves out of the service area of the first data network, and sends a first data network PDN user plane deleting command to the UPF; after receiving a first data network PDN user plane deletion command, the UPF sends a first data network PDN user plane deletion request to the SMF; after receiving the first data network PDN user plane deletion request, the SMF deletes the first data network PDN user plane, sends a first data network PDN user plane deletion response to the UPF, and stops sending a notification message of subscribing downlink data arrival to the UPF, thereby completing the deletion process of the first data network PDN user plane.

In the embodiment of the invention, when the terminal equipment moves out of the service area of the first data network, the network equipment deletes the PDN user plane of the first data network; therefore, occupation of MEC resources of the first data network by the terminal device is reduced.

Optionally, in this embodiment of the present invention, with reference to fig. 4, after S404b shown in fig. 4, S501-S503 may also be executed:

s501, the terminal device sends a first data network PDN user plane establishment request to the network device.

The first data network PDN user plane establishing request is used for requesting the network equipment to rebuild the first data network PDN user plane.

S502, the network equipment refuses to receive a first data network PDN user plane establishment request sent by the terminal equipment.

For example, when the terminal device is out of the service range of the LADN, the SMF of the network device may reject the user plane establishment request from the terminal device to the LADN.

S503, the network equipment refuses to rebuild the PDN user plane of the first data network.

Illustratively, after the SMF rejects the user plane establishment request from the terminal device to the LADN, the SMF does not initiate a request to the UPF to reestablish the user plane connection to the LADN.

Optionally, in the embodiment of the present invention, when the terminal device moves out of the service area of the first data network, the network device may also directly delete the PDN session of the first data network. Specifically, in conjunction with fig. 4, as shown in fig. 6, S404 may be replaced with S404':

s404', if the terminal device moves out of the service area of the first data network, the network device deletes the PDN conversation of the first data network.

Exemplarily, after receiving the current location information, the SMF determines that the terminal device moves out of the service area of the first data network, and sends a request for deleting the PDN session of the first data network to the UPF; and after receiving the first data network PDN session deletion request, the UPF deletes the first data network PDN session, and sends a first data network PDN session deletion response to the SMF to complete the deletion process of the first data network PDN session.

In the embodiment of the invention, when the terminal equipment moves out of the service area of the first data network, the network equipment directly deletes the PDN session of the first data network; therefore, occupation of MEC resources of the first data network by the terminal device is further reduced.

Optionally, in this embodiment of the present invention, in combination with fig. 6, after S404' shown in fig. 6, S701 and S702 (or S703) may also be executed:

s701, the network equipment sends a first data network PDN session deletion message to the terminal equipment.

When the terminal device moves out of the service area of the first data network, the network device sends a first data network PDN session deletion message to the terminal device after deleting the first data network PDN session, wherein the first data network PDN session deletion message is used for notifying the UE that the first data network PDN session is deleted.

S702, when the terminal equipment receives a first data network PDN session deletion message sent by the network equipment, the terminal equipment determines that the first data network PDN session is deleted by the network equipment.

Illustratively, the first data network PDN session reestablishment request may be sent to the network device upon a first data network PDN reconnection with the network device after the terminal device determines that the network device has deleted the first data network PDN session.

And S703, when the terminal equipment does not receive the first data network PDN session deletion message, the terminal equipment determines that the first data network PDN user plane is deleted.

Illustratively, when the terminal device does not receive the first data network PDN session deletion message, the terminal device considers that the network device deletes the first data network PDN user plane and does not delete the first data network PDN session; when the terminal device reconnects the first data network PDN with the network device, it may send a request for reestablishing the first data network PDN user plane to the network device.

S404c, if the terminal device returns to the service area of the first data network within the preset duration after moving out of the service area of the first data network, the network device reconstructs the PDN user plane of the first data network.

After determining that the terminal device moves out of the service area of the first data network, the network device starts a timer and starts timing, and when determining that the terminal device returns to the service area of the first data network within a preset time length, the network device rebuilds the PDN user plane of the first data network.

Illustratively, as shown in fig. 7, the network device determines that the terminal device moves out of the service area of the first data network at time t1, and the network device starts counting at time t1 with a preset duration of time from the time t1 to the time t 2. The network device reestablishes the first data network PDN user plane when the terminal device returns to the service area of the first data network at any time between time t1 and time t 2.

The network equipment determines that the terminal equipment returns to the service area of the first data network within a preset time length after moving out of the service area of the first data network, and after receiving a service request sent by the terminal equipment, the network equipment rebuilds a PDN user plane of the first data network.

Illustratively, the network device determines that the terminal device returns to the service area of the first data network within a preset duration after moving out of the service area of the first data network. After receiving a service request sent by terminal equipment, the AMF sends a first data network PDN user plane reestablishment request to the SMF; the SMF sends a first data network PDN user plane reconstruction request to the UPF; the UPF rebuilds the PDN user plane of the first data network according to the PDN user plane rebuilding request of the first data network, and sends a PDN user plane rebuilding response of the first data network to the AMF through the SMF; and after receiving the user plane reestablishment response of the first data network PDN, the AMF sends a context establishing request to the RAN, establishes a radio bearer with the terminal equipment and completes the user plane reestablishment process of the first data network PDN.

In the embodiment of the present invention, when the terminal device returns to the service area of the first data network within the preset duration after moving out of the service area of the first data network, the network device may reconstruct the PDN user plane of the first data network. Because the terminal device is located in the service area of the first data network, that is, when the terminal device is located near the network device, the network device can use the MEC resource of the first data network to perform service transmission with the terminal device, thereby reducing the end-to-end delay and the load of the transmission network, realizing efficient service interaction, and improving the service experience of the user.

Optionally, in the embodiment of the present invention, when the terminal device moves out of the service area of the first data network and the network device deletes the PDN session of the first data network, and when the terminal device returns to the service area of the first data network within a preset time period after moving out of the service area of the first data network, the network device reestablishes the PDN session of the first data network.

S404d, if the terminal device does not return to the service area of the first data network within the preset time after moving out of the service area of the first data network, the network device deletes the PDN session of the first data network.

After determining that the terminal device moves out of the service area of the first data network, the network device starts a timer and starts timing, and when determining that the terminal device does not return to the service area of the first data network within a preset time period, the network device deletes the PDN session of the first data network.

Illustratively, the network device determines that the terminal device moves out of the service area of the first data network at time t1 shown in fig. 7, and the network device starts counting at time t1 with a preset duration of time from the time t1 to the time t 2. The network device deletes the first data network PDN session when the terminal device does not return to the service area of the first data network at any time between time t1 and time t 2.

For example, when the AMF of the network device receives current location information sent by the terminal device (the current location information is used to represent that the terminal device does not return to the service area of the first data network within a preset time period after moving out of the service area of the first data network), the current location information is sent to the SMF; after receiving the current position information, the SMF determines that the terminal equipment does not return to the service area of the first data network within a preset time length after moving out of the service area of the first data network, and sends a first data network PDN session deletion request to the UPF; and after receiving the first data network PDN session deletion request, the UPF deletes the first data network PDN session, and sends a first data network PDN session deletion response to the SMF to complete the deletion process of the first data network PDN session.

In the embodiment of the invention, when the terminal equipment does not return to the service area of the first data network within the preset time length after moving out of the service area of the first data network, the network equipment deletes the PDN user plane of the first data network and the PDN session of the first data network; therefore, occupation of the MEC resources of the first data network by the terminal equipment is completely released.

The embodiment of the invention provides a method for processing an MEC based on a position, wherein a network device determines the position change of a terminal device according to current position information reported by the terminal device, and correspondingly processes the MEC resource of a first data network according to the position change of the terminal device.
