Description

Technical Field

[0001] The present application relates to the field of computer and communication technology, and more specifically, to a communication processing method, apparatus, medium and equipment based on an edge computing platform. Background Art

[0002] At present, 5G networks have achieved a complete separation of the control plane and the user plane. The deployment of user plane functional entities usually adopts a multi-level approach. Especially in the edge computing scenario, edge user plane functional entities and local user plane functional entities will be deployed separately. Multiple edge user plane functional entities will aggregate user data traffic to the local user plane functional entity, which will then be sent to the network by the local user plane functional entity and finally reach the service scheduling server in the cloud. Of course, depending on the load situation, the local user plane functional entity can also be further aggregated to a higher-level user plane functional entity before entering the network and finally reaching the service scheduling server in the cloud.

[0003] However, in the edge computing scenario, the edge application server is deployed at the edge site, and the service scheduling is uniformly implemented by the service scheduling server deployed in the cloud. However, under this network architecture, the service scheduling server in the cloud cannot make effective scheduling. The reason is that after the service access request of the terminal device is converged to the local user plane function entity through the edge user plane function entity, it will be sent from the public network exit of the local user plane function entity, and finally reach the service scheduling server in the cloud through the network. At this time, the source address of the IP packet of the service access request received by the service scheduling server will be the public network address of the local user plane function entity, which makes it impossible for the service scheduling server to make correct scheduling. Summary of the invention

[0004] The embodiments of the present application provide a communication processing method, apparatus, medium and equipment based on an edge computing platform, which can enable the service scheduling server to make effective and accurate scheduling of the service access request of the terminal device to a certain extent, thereby reducing the service access delay of the terminal device.

[0035] Figure 1 A schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied is shown.

[0036] like Figure 1 As shown, the system architecture 100 may include a terminal device 101 , an edge computing platform 102 , a local user plane functional entity 103 , and a service scheduling server 104 .

[0037] Among them, the terminal device 101 can be various electronic devices with a display screen, including but not limited to desktop computers, portable computers, smart phones, tablet computers and cameras, etc., and multiple application (application, APP for short) clients can be installed on the terminal device 101. Users can initiate business requests through different clients to obtain corresponding business data.

[0038] The edge computing platform 102 is deployed at the edge of the network close to the terminal device 101 or the data source, and can use the wireless access network to provide the services and cloud computing functions required by the terminal device 101 nearby, thereby creating a service environment with high performance, low latency and high bandwidth, accelerating the rapid download of various content, services and applications in the network, and allowing users to enjoy an uninterrupted high-quality network experience. In the embodiment of the present application, the edge computing platform 102 includes an edge user plane functional entity 1021, an edge application server 1022 and a business scheduling auxiliary module 1023.

[0039] The edge user plane function entity 1021 is used to forward the service access request or service access request of the terminal device 101, and the edge application server 1022 is used to process the service access request of the terminal device 101 and provide the terminal device 101 with the service data it needs.

[0040] The service scheduling auxiliary module 1023 is used to process the service access request of the terminal device 101 forwarded by the edge user plane function entity 1021, so that the processed service access request contains the network address of the edge application server 1022. In an exemplary embodiment, the service scheduling auxiliary module 1023 processes the service access request by adding the network address of the edge application server 1022 in the request header of the service access request, or by adding the network address of the edge application server 1022 in the request body of the service access request.

[0041] It is worth noting that the service scheduling auxiliary module 1023 can be deployed independently of the edge application server 1022 , or the service scheduling auxiliary module 1023 can be deployed in the edge application server 1022 .

[0042] The service scheduling server 104 may be composed of one server or multiple servers. The service scheduling server 104 may schedule the edge application server 1022 to provide service data for the terminal device 101 .

[0043] In one embodiment of the present application, the service scheduling auxiliary module 1023 can send the configured traffic unloading policy to the edge user plane functional entity 1021, and the traffic unloading policy is used to instruct the edge user plane functional entity 1021 to send the service access request to the service scheduling auxiliary module 1023 when it detects that the destination address of the service access request of the terminal device 101 is the network address of the specified service scheduling server, so that the service scheduling auxiliary module 1023 can process the service access request.

[0044] In one embodiment of the present application, the terminal device 101 can send a service access request to the edge user plane functional entity 1021 through the wireless access network. When the edge user plane functional entity 1021 detects that the destination address of the service access request is the network address of the specified service scheduling server, the service access request is sent to the service scheduling auxiliary module 1023. After modifying the service access request, the service scheduling auxiliary module 1023 can return the modified service access request to the edge user plane functional entity 1021.

[0045] In one embodiment of the present application, after receiving the modified service access request, the edge user plane functional entity 1021 can send the modified service access request to the network via the local user plane functional entity 103, and finally reach the service scheduling server 104, so that the service scheduling server 104 returns a service access response message containing the network address of the edge application server 1022.

[0046] In one embodiment of the present application, after receiving the service access response message returned by the service scheduling server 104, the edge user plane functional entity 1021 can send the service access response message to the terminal device 101, and then the terminal device 101 can send a service access request to the edge application server 1022 according to the network address of the edge application server 1022 contained in the service access response message.

[0047] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0048] Figure 2 A flow chart of a communication processing method based on an edge computing platform according to an embodiment of the present application is shown, wherein the edge computing platform includes an edge user plane functional entity, a service scheduling auxiliary module, and an edge application server. Figure 2 The communication processing method based on the edge computing platform shown can be performed by an edge user plane functional entity, such as Figure 1 The edge user plane function entity 1021 shown in FIG. Figure 2 As shown, the method includes:

[0049] Step S210: receiving a service access request sent by a terminal device;

[0050] Step S220: If the destination address of the service access request is the network address of the designated service scheduling server, the service access request is sent to the service scheduling auxiliary module;

[0051] Step S230: receiving a modified service access request returned by the service scheduling auxiliary module, wherein the modified service access request includes a network address of an edge application server;

[0052] Step S240: Send the modified service access request to the designated service scheduling server, so that the designated service scheduling server returns a service access response message including the network address of the edge application server;

[0053] Step S250: If a service access response message is received, the service access response message is sent to the terminal device, so that the terminal device initiates a service access request to the edge application server according to the network address of the edge application server.

[0054] These steps are described in detail below.

[0055] In step S210, a service access request sent by a terminal device is received.

[0056] Specifically, the service access request is an HTTP request sent by the terminal device to the service scheduling server in an existing manner. The terminal device sends the service access request to the service scheduling server to request the service scheduling server to schedule an edge application server for the terminal device so that the terminal device can access the service through the edge application server.

[0057] It is understandable that the service scheduling server is a server that can schedule edge application servers to process service access requests of terminal devices, wherein the service access requests of terminal devices may be, for example, requests to access a web page or requests to download data.

[0058] As mentioned before, the 5G network achieves a complete separation of the control plane and the user plane. Especially in the edge computing scenario, multi-level user plane functional entities are deployed. Therefore, the edge user plane functional entity can receive service access requests sent by terminal devices through the wireless access network.

[0059] In step S220, if the destination address of the service access request is the network address of the designated service scheduling server, the service access request is sent to the service scheduling auxiliary module.

[0060] Here, after receiving the access request of the terminal device, if the edge user plane functional entity detects that the destination address of the service access request is the network address of the designated service scheduling server, it may send the service access request to the service scheduling auxiliary module.

[0061] It needs to be explained that the service scheduling auxiliary module is a newly added module in the edge computing platform, which also includes an edge user plane functional entity and an edge application server. The service scheduling auxiliary module can be deployed in the edge application server or independently deployed from the edge application server.

[0062] In one embodiment of the present application, the edge user plane functional entity is a 5G user plane device, and one of its main functions is to unload the uplink or downlink traffic passing through the edge user plane functional entity according to the corresponding policy configuration in the edge computing scenario. Therefore, before the edge user plane functional entity sends the service access request to the service scheduling auxiliary module, the method also includes:

[0063] The traffic unloading policy configured by the service scheduling auxiliary module is received, where the traffic unloading policy is used to instruct the edge user plane function entity to forward the service access request to the service scheduling auxiliary module when detecting that the destination address of the service access request is the network address of the designated service scheduling server.

[0064] In this embodiment, the service scheduling auxiliary module can send the configured traffic unloading policy to the edge user plane functional entity, so that the edge user plane functional entity can forward the service access request according to the traffic unloading policy. If the edge user plane functional entity detects that the destination address of the service access request is the network address of the specified service scheduling server according to the traffic unloading policy, the service access request is forwarded to the service scheduling auxiliary module. Conversely, if the edge user plane functional entity detects that the destination address of the service access request is not the network address of the specified service scheduling server according to the traffic unloading policy, the edge user plane functional entity can send the service access request to the service scheduling server corresponding to the destination address of the service access request.

[0065] In one embodiment of the present application, the edge user plane functional entity can send the service access request to the service scheduling auxiliary module through a tunnel. Sending the service access request through a tunnel can prevent the message of the service access request from being modified, thereby ensuring the integrity of the service access request. The tunnel can be a Generic Routing Encapsulation tunnel (GRE) or other tunnels, which are not specifically limited in the embodiments of the present application.

[0066] Step S230: Receive the modified service access request returned by the service scheduling auxiliary module, where the modified service access request includes the network address of the edge application server.

[0067] The service scheduling auxiliary module can be used to process the service access request, and its processing method can be to modify the service access request so that the modified service access request contains the network address of the edge application server. As before, the edge application server, the service scheduling auxiliary module and the edge user plane functional entity are in the same edge computing platform. The edge application server is a service server that can provide low latency and high-quality experience for terminal devices, such as a content delivery network (CDN) or a cloud tour server.

[0068] In one embodiment of the present application, the edge user plane function entity may send the service access request to the service scheduling auxiliary module through the tunnel, and accordingly, the service scheduling auxiliary module may also return the modified service access request to the edge user plane function entity through the tunnel. The tunnel may be a Generic Routing Encapsulation tunnel (GRE) or other tunnels, which are not limited in the embodiments of the present application.

[0069] Step S240: Send the modified service access request to the designated service scheduling server, so that the designated service scheduling server returns a service access response message including the network address of the edge application server.

[0070] Specifically, after receiving the modified service access request returned by the service scheduling auxiliary module, the edge user plane functional entity can send the service access request to the designated service scheduling server through the core network. After receiving the modified service access request, the designated service scheduling server can determine whether the modified service access request contains the network address of the edge application server. If so, it means that the edge application server can process the service access request of the terminal, and then return a service access response message containing the network address of the edge application server to the edge user plane functional entity.

[0071] In step S250, after receiving the service access response message, the edge user plane functional entity will directly forward the service access response message to the terminal device. The terminal device can obtain the network address of the edge application server according to the service access response message, and thus initiate a service access request according to the network address of the edge application server.

[0072] In the prior art, in order to solve the problem that the service scheduler cannot accurately perform service scheduling, the industry has developed a variety of solutions. For example, by modifying the terminal device, the service access request sent by the terminal device carries special data (such as the terminal geographic location information of the terminal device), and at the same time, the service scheduling logic of the service scheduling server is modified so that the service scheduling server can make correct scheduling according to the geographic location information of the terminal device. For example, by modifying the function of the edge user plane functional entity, when the service access request of the terminal device passes through the edge user plane functional entity, the identifier of the edge user plane functional entity is added to the service access request. When the service access request passes through the edge user plane functional entity and reaches the service scheduling server in the cloud, the service scheduling server can make correct service scheduling according to the identifier of the edge user plane functional entity. Of course, this method also requires modifying the processing logic of the service scheduling server.

[0073] Compared with the prior art, the present application is based on the technical solution provided by the above embodiments, by adding a service scheduling auxiliary module to the edge computing platform, and the service scheduling auxiliary module modifies the service access request so that the modified service access request contains the network address of the edge application server, so that after the designated service scheduling server receives the modified service access request, it can make effective and accurate scheduling for the service access request of the terminal device according to the network address of the edge application server, thereby reducing the service access delay of the terminal device, and the solution is simple and easy to implement. At the same time, since it does not involve modifications to the terminal device or the edge user plane functional entity, it greatly reduces the cost of service upgrades and does not bring challenges to the entire service scheduling software and hardware system. In addition, by adding a new service scheduling auxiliary module to the edge computing platform, the modification of the service access request by the service scheduling auxiliary module can be fully compatible with the original service scheduling logic, thereby ensuring the compatibility of the service scheduling function.

[0074] Figure 3 A flow chart of a communication processing method based on an edge computing platform according to an embodiment of the present invention is shown, referring to Figure 3 As shown, after sending the service access response message to the terminal device through step S250, the communication processing method based on the edge computing platform also includes steps S310 to S330, which are described in detail as follows:

[0075] Step S310: Receive a service access request sent by a terminal device, where the service access request includes a network address of an edge application server.

[0076] Among them, the service access request is a request sent by the terminal device to the edge application server, for example, a web page access request, a data download request, etc. of the terminal device. After receiving the service access response message, the terminal device can obtain the network address of the edge application server that can process the service access request of the terminal device from the service access response message, and then send the service access request according to the network address of the edge application server. The service access request of the terminal device will be sent to the edge user plane functional entity in the edge computing platform through the wireless access network.

[0077] Step S320: Send the service access request to the edge application server.

[0078] Specifically, after the terminal device sends a service access request to the edge user plane functional entity, the edge user plane functional entity forwards the service access request to the edge application server, so that the edge application server can respond to the service access request.

[0079] Step S330: If a service response result for the service access request returned by the edge application server is received, the service response result is returned to the terminal device.

[0080] If the edge user plane functional entity receives a service response result for the service access request returned by the edge application server, it forwards the service response result to the terminal device.

[0081] Figure 4 A flow chart of a communication processing method based on an edge computing platform according to an embodiment of the present invention is shown. The edge computing platform includes an edge user plane functional entity, a service scheduling auxiliary module and an edge application server. The communication processing method can be executed by the service scheduling auxiliary module. Figure 4 As shown, the communication processing method at least includes steps S410 to S430, which are described in detail as follows:

[0082] Step S410: Receive a service access request from a terminal device sent by an edge user plane function entity, where the destination address of the service access request is the network address of a designated service scheduling server.

[0083] Specifically, the service access request is an HTTP request sent by the terminal device to the designated service scheduling server in an existing manner. The terminal device sends the service access request whose destination address is the network address of the designated service scheduling server to the edge user plane functional entity. When the edge user plane functional entity detects that the destination address of the service access request is the network address of the designated service scheduling server, it forwards the service access request to the service scheduling auxiliary module.

[0084] In one embodiment of the present application, before the service scheduling auxiliary module receives the service access request, the communication processing method further includes:

[0085] The traffic offloading policy is sent to the edge user plane functional entity, where the traffic offloading policy is used to instruct the edge user plane functional entity to forward the service access request to the service scheduling auxiliary module when detecting that the destination address of the service access request is the network address of the designated service scheduling server.

[0086] As before, the service scheduling auxiliary module can send the configured traffic unloading policy to the edge user plane functional entity. In this way, the edge user plane functional entity can forward the service access request according to the traffic unloading policy, which can specifically include: if the edge user plane functional entity detects that the destination address of the service access request is the network address of the specified service scheduling server according to the traffic unloading policy, the service access request can be forwarded to the service scheduling auxiliary module; conversely, if the edge user plane functional entity detects that the destination address of the service access request is not the network address of the specified service scheduling server according to the traffic unloading policy, the edge user plane functional entity can send the service access request to the service scheduling server corresponding to the destination address of the service access request.

[0087] Step S420: modify the service access request to obtain a modified service access request, wherein the modified service access request includes the network address of the edge application server.

[0088] Since the service scheduling auxiliary module is a newly added module in the edge computing platform, which is used to process the service access request, in this step, after receiving the service access request, the service scheduling auxiliary module can modify the service access request so that the modified service access request can contain the network address of the edge application server. The edge application server is a server that can process the service access request of the terminal. The service scheduling auxiliary module and the edge application server are deployed in the same edge computing platform, wherein the service scheduling auxiliary module can be deployed independently of the edge application server or can be co-located with the edge application server.

[0089] In one embodiment of the present application, the service scheduling auxiliary module may modify the service access request by modifying the request header. In this embodiment, step S420 specifically includes:

[0090] The network address of the edge application server is added to the request header of the service access request to obtain a modified service access request.

[0091] In another embodiment of the present application, the service scheduling auxiliary module may modify the service access request by modifying the request body. In this embodiment, step S420 specifically includes:

[0092] The network address of the edge application server is added to the request body of the service access request to obtain a modified service access request.

[0093] Step S430: Send the modified service access request to the edge user plane function entity, so that the edge user plane function entity sends the modified service access request to the designated service scheduling server. The modified service access request is used to enable the designated service scheduling server to return a service access response message containing the network address of the edge application server to the terminal device.

[0094] It is easy to understand that after the service scheduling auxiliary module modifies the service access request, it can send the modified service access request to the edge user plane functional entity, and the edge user plane functional entity continues to forward the modified service access request to the designated service scheduling server, so that the designated service scheduling server responds to the modified service access request and returns a service access response message containing the network address of the edge application server.

[0095] In one embodiment of the present application, in order to ensure that the service access request of the terminal device does not change before being sent to the service scheduling auxiliary module for processing, the service access request can be sent to the service scheduling auxiliary module in a tunnel manner, and the service scheduling auxiliary module returns it through the original tunnel. In this embodiment, step S410 specifically includes: receiving the service access request from the terminal device sent by the edge user plane functional entity through the general routing encapsulation tunnel; step S430 specifically includes: sending the modified service access request to the edge user plane functional entity through the general routing encapsulation tunnel.

[0096] It should be noted that the Generic Routing Encapsulation (GRE) protocol encapsulates data packets of certain network layer protocols so that these encapsulated data packets can be transmitted in another network layer protocol. The GRE protocol is essentially an encapsulation protocol that provides a mechanism for encapsulating packets of one protocol in packets of another protocol, so that packets can be transmitted in heterogeneous networks. The transmission channel is called a tunnel.

[0097] For example, assuming that the network address of the terminal device is 33.3.3.3 and the network address of the designated service scheduling server is 11.2.2.2, the source address of the service access request sent by the terminal device to the designated service scheduling server is 33.3.3.3 and the destination address is 11.2.2.2.

[0098] When a terminal device sends a service access request to a designated service scheduling server, the terminal device may first send the service access request to an edge user plane functional entity. After receiving the service access request, the edge user plane functional entity may encapsulate an outer header outside the message of the service access request to form a GRE message.

[0099] Assume that the interface address corresponding to the general routing encapsulation tunnel port on the edge user plane functional entity is 22.1.1.1, and the interface address corresponding to the general routing encapsulation tunnel port on the service scheduling auxiliary module is 11.1.1.1. The outer source address of the encapsulated GRE message is the interface address corresponding to the GRE tunnel port on the edge user plane functional entity (i.e., 22.1.1.1), the outer destination address is the interface address corresponding to the GRE tunnel port on the service scheduling auxiliary module (i.e., 11.1.1.1), the inner source address of the GRE message is the network address of the terminal device (i.e., 33.3.3.3), and the inner destination address is the network address of the designated service scheduling server (i.e., 11.2.2.2).

[0100] After encapsulating the service access request to form a GRE message, the edge user plane functional entity sends the GRE message to the service scheduling auxiliary module. After receiving the GRE message sent by the edge user plane functional entity, the service scheduling auxiliary module can decapsulate the GRE message to obtain the service access request, modify the service access request, and then encapsulate the modified service access request, and return the modified service access request to the edge user plane functional entity through the interface corresponding to the general routing encapsulation tunnel port.

[0101] Figure 5 An interactive flow chart of a communication processing method based on an edge computing platform according to an embodiment of the present application is shown. The edge computing platform includes an edge user plane functional entity, a service scheduling auxiliary module and an edge application server. The communication processing method includes the following steps:

[0102] Step S510: the service scheduling auxiliary module sends a traffic offload policy to the edge user plane functional entity, wherein the traffic offload policy is used to instruct the edge user plane functional entity to forward the service access request to the service scheduling auxiliary module when detecting that the destination address of the service access request of the terminal device is the network address of the designated service scheduling server.

[0103] Step S520: The edge user plane function entity receives a service access request sent by the terminal device.

[0104] Step S530: The edge user plane function entity sends the service access request of the terminal device to the service scheduling auxiliary module.

[0105] As before, after the edge user plane functional entity receives the traffic offload policy, if the edge user plane functional entity detects that the destination address of the service access request is the network address of the designated service scheduling server according to the instruction of the traffic offload policy, the service access request can be sent to the service scheduling auxiliary module. Conversely, if the edge user plane functional entity detects that the destination address of the service access request is not the network address of the designated service scheduling server according to the instruction of the traffic offload policy, the edge user plane functional entity will not send the service access request to the service scheduling auxiliary module.

[0106] In one embodiment of the present application, the edge user plane functional entity can send the service access request of the terminal device to the service scheduling auxiliary module through a general routing encapsulation tunnel. Sending through the general routing encapsulation tunnel can ensure that the service access request sent to the service scheduling auxiliary module will not change.

[0107] Step S540: The service scheduling auxiliary module modifies the service access request, and the modified service access request includes the network address of the edge application server.

[0108] Optionally, the service scheduling auxiliary module can be modified by adding the network address of the edge application server in the request header of the service access request, or by adding the network address of the edge application server in the request body of the service access request. Of course, other methods can also be used so that the service access request modified by the service scheduling auxiliary module contains the network address of the edge application server.

[0109] Step S550: The service scheduling auxiliary module returns the modified service access request to the edge user plane function entity.

[0110] In one embodiment of the present application, the edge user plane functional entity sends the service access request of the terminal device to the service scheduling auxiliary module through the general routing encapsulation tunnel. After the service scheduling auxiliary module modifies the service access request, the service scheduling auxiliary module can return the modified service access request to the edge user plane functional entity through the general routing encapsulation tunnel.

[0111] Step S560: The edge user plane function entity sends the modified service access request to the service scheduling server.

[0112] It can be understood that after receiving the modified service access request, the edge user plane functional entity can further forward the modified service access request to the service scheduling server.

[0113] Step S570: The service scheduling server returns a service access response message including the network address of the edge application server to the edge user plane function entity.

[0114] Specifically, the service scheduling server receives the modified service access request and can determine that the edge application server can process the service request of the terminal device based on the network address of the edge application server contained in the modified service access request, and then generate a service access response message containing the network address of the edge application server and return it to the edge user plane functional entity.

[0115] Step S580: The edge user plane function entity sends a service access response message to the terminal device.

[0116] Step S590: After receiving the service access response message, the terminal device sends a service access request to the edge application server according to the network address of the edge application server included in the service access response message. The service access request of the terminal device can be sent to the edge user plane function entity through the wireless access network, and the edge user plane function entity forwards the service access request to the edge application server.
