Fig. 1 shows a schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied.
As shown in fig. 1, the system architecture 100 may include a terminal device 101 (the terminal device 101 may be a smart phone shown in fig. 1, and may also be a tablet computer, a laptop computer, a desktop computer, etc.), a User Plane Function (UPF) 102, a core network, a service scheduler 103 located in the core data center, and an edge computing platform 104 connected to the User Plane Function 102.
It should be understood that the number of terminal devices 101, user plane functional entities 102, traffic schedulers 103, and edge computing platforms 104 shown in fig. 1 is merely illustrative. There may be any number of terminal devices 101, user plane functional entities 102, service schedulers 103, and edge computing platforms 104, as desired for the implementation.
In an embodiment of the present application, the terminal device 101 may send a DNS (Domain Name System) query request to the user plane functional entity 102, where the DNS query request is used to indicate that network location information of an edge computing platform needs to be acquired. After receiving the DNS query request sent by the terminal device 101, the user plane functional entity 102 forwards the DNS query request to a DNS server located in the edge computing platform 104, and then the DNS server returns a DNS response message containing network location information of the edge computing platform. After receiving the DNS response message, the user plane functional entity 102 returns the DNS response message to the terminal device 101.
In an embodiment of the present application, after receiving the DNS response message, the terminal device 101 may acquire the network location information of the edge computing platform from the DNS response message, and then send a service scheduling request to the user plane functional entity 102, where the service scheduling request includes the network location information of the edge computing platform. After receiving the service scheduling request, the user plane functional entity 102 forwards the service scheduling request to the service scheduler 103 through the core network, and after receiving the service scheduling request, the service scheduler 103 may preferentially allocate, to the terminal device 101, a service server deployed in the edge computing platform 104 according to the network location information of the edge computing platform included in the service scheduling request, generate a service scheduling response message based on the service server allocated to the terminal device 101, and then return the service scheduling response message to the user plane functional entity 102 through the core network.
In an embodiment of the present application, after receiving the service scheduling response message returned by the service scheduler 103, the user plane functional entity 102 returns the service scheduling response message to the terminal device 101. After receiving the service scheduling response message, the terminal device 101 may initiate a service access request to the service server included in the service scheduling response message. For example, the terminal device 101 may initiate a file download request to the service server, and then the file download request may be routed to the service server in the edge computing platform 104 by the user plane functional entity 102, and then the service server may return a service access response message containing the target file requested to be downloaded to the terminal device 101 through the user plane functional entity 102.
Therefore, according to the technical scheme of the embodiment of the application, the service scheduler 103 can allocate the service server located in the edge computing platform 104 to the terminal device 101 as much as possible according to the network location information of the edge computing platform included in the service scheduling request to process the service access request, so that the terminal device 101 can be ensured to obtain a lower time delay, the service experience of the terminal device 101 is improved, and meanwhile, the service server in the edge computing platform 104 can be effectively and reasonably controlled through the service scheduler 103.

Referring to fig. 2, the communication processing method at least includes steps S210 to S240, and the following is described in detail:
in step S210, a service scheduling request from a terminal device is received, where the service scheduling request includes network location information of an edge computing platform.
In an embodiment of the present application, the service scheduling request sent by the terminal device may be sent to the base station device first, and then forwarded to the user plane function entity by the base station device.
In an embodiment of the present application, before receiving the service scheduling request from the terminal device in step S210, if the user plane functional entity receives the DNS request from the terminal device, the DNS request may be forwarded to a DNS server located in the edge computing platform, so that the DNS server returns a DNS response message containing the network address information of the edge computing platform. If the user plane functional entity receives a DNS response message returned by the DNS server, the DNS response message may be forwarded to the terminal device, so that the terminal device can obtain the network address information of the edge computing platform from the DNS response message, and further initiate a service scheduling request based on the network address information of the edge computing platform.
In step S220, the service scheduling request is forwarded to a service scheduler, so that the service scheduler allocates a service server to the terminal device according to the network location information of the edge computing platform.
In an embodiment of the present application, the process of forwarding the service scheduling request to the service scheduler by the edge computing device may be to first send the service scheduling request to the core network device, and then the core network device sends the service scheduling request to the service scheduler. Optionally, the traffic scheduler is located within the core data center.
Continuing to refer to fig. 2, in step S230, a service scheduling response message returned by the service scheduler is received, where the service scheduling response message includes information of the service server allocated by the service scheduling.
In one embodiment of the present application, the service scheduling response message returned by the service scheduler may be a service scheduling response message forwarded by the receiving core network device from the service scheduler.
The process of allocating the service server to the terminal device by the service scheduler according to the network location information of the edge computing platform may be to preferentially allocate the service server deployed in the edge computing platform. And if the fact that no available service server in the edge computing platform is allocated to the terminal equipment is determined according to the network position information of the edge computing platform, allocating the service server deployed in the core data center to the terminal equipment.
In step S240, the service scheduling response message is returned to the terminal device, so that the terminal device initiates a service access request to the service server included in the service scheduling response message.
The technical scheme of the embodiment shown in fig. 2 enables the service scheduler to allocate the service server located in the edge computing platform to the terminal device as much as possible according to the network location information of the edge computing platform included in the service scheduling request to process the service access request, thereby ensuring that the terminal device obtains a lower time delay, improving the service experience of the terminal device, and simultaneously, effectively and reasonably managing and controlling the service server in the edge computing platform through the service scheduler.
Based on the technical solution of the embodiment shown in fig. 2, as shown in fig. 3, in an embodiment of the present application, after returning the service scheduling response message to the terminal device, the method may further include the following steps:
step S310, if a service access request initiated by a terminal device to a service server is received, forwarding the service access request to the service server.
In an embodiment of the present application, a service access request initiated by a terminal device includes address information of a service server, and a user plane functional entity may forward the service access request to a corresponding service server after receiving the service access request.
Step S320, receiving a service access response message for the service access request returned by the service server, and forwarding the service access response message to the terminal device.
In an embodiment of the present application, the service access request may be a file download request, and after the user plane functional entity forwards the file download request to the service server, a service access response message returned by the service server includes a target file requested to be downloaded by the terminal device, and further forwards the service access response message including the target file to the terminal device.
In an embodiment of the present application, the service access request may be an access request, and then after the user plane functional entity forwards the access request to the service server, a service access response message returned by the service server includes an access confirmation message, and further forwards the service access response message including the access confirmation message to the terminal device.
In an embodiment of the application, the service access request may be an acquisition request of the car networking data, and then after the user plane functional entity forwards the acquisition request of the car networking data to the service server, a service access response message returned by the service server contains target car networking data requested to be acquired by the terminal device, and further forwards the service access response message containing the target car networking data to the terminal device.
Fig. 4 shows a flow diagram of a communication processing method according to an embodiment of the present application, which may be performed by the traffic scheduler 103 shown in fig. 1. Referring to fig. 4, the communication processing method at least includes steps S410 to S440, and the following is described in detail:
in step S410, a service scheduling request from a terminal device forwarded by a user plane function entity is received, where the service scheduling request includes network location information of an edge computing platform.
In an embodiment of the present application, the service scheduling request sent by the terminal device may be sent to the base station device first, and then forwarded to the user plane function entity by the base station device.
In step S420, a service server deployed on the edge computing platform is allocated to the terminal device according to the network location information of the edge computing platform.
In an embodiment of the present application, a service server deployment record of an edge computing platform may be obtained according to network location information of the edge computing platform, and then a service server is allocated to a terminal device based on the service server deployment record of the edge computing platform. For example, the service servers available in the edge computing platform are allocated to the terminal device according to the service server deployment record of the edge computing platform, so that the terminal device is ensured to obtain lower time delay through the service processing server in the edge computing platform.
In an embodiment of the present application, if it is determined that there is no available service server in the edge computing platform to allocate to the terminal device according to the network location information of the edge computing platform, the service server deployed in the core data center is allocated to the terminal device. In this embodiment, in the case that there is no available service server in the edge computing platform, the service server deployed in the core data center is allocated to the terminal device, so that it is ensured that the service access request of the terminal device can be responded to in time.
In step S430, a service scheduling response message is generated according to the service server allocated to the terminal device.
In an embodiment of the present application, the generated service scheduling response message includes address information of a service server allocated to the terminal device, and the terminal device may initiate a service access request based on the address information of the service server.
In step S440, the service scheduling response message is returned to the user plane functional entity, so that the user plane functional entity returns the service scheduling response message to the terminal device.
In an embodiment of the present application, the service scheduler may send the service scheduling response message to the core network device, and then the core network device returns the service scheduling response message to the user plane functional entity, and the user plane functional entity forwards the service scheduling response message to the terminal device. After receiving the service scheduling response message, the terminal device may initiate a service access request based on the address information of the service server in the service scheduling response message.
