In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0038] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0040] It should be noted that the "multiple" mentioned in this article refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0041] With the large-scale commercial deployment of 5G networks, mobile edge computing, as an important feature of 5G networks, has gradually entered the stage of solution implementation. The deployment of edge services usually faces the following two scenarios:

[0042] like Figure 1 The figure shows a proprietary MEC deployment scenario for large enterprises. In this deployment scenario, the edge computing platform 102 is deployed at a specific location in the network, and an edge user plane functional entity 1021 and an edge service server 1022 are deployed in the edge computing platform 102. The service access request of the terminal device 101 can be unloaded to the edge service server 1022 in the edge computing platform 102 through the edge user plane functional entity 1021, and the edge service server 1022 deployed on the edge computing platform 102 provides services for the terminal device 101.

[0043] like Figure 2 The figure shows a MEC deployment scenario for ordinary consumers. In this deployment scenario, the edge computing platform 202 is deployed at a specific location in the network, and the edge user plane functional entity 2021 and the edge service server 2022 are deployed in the edge computing platform 202. Considering the continuity of user services and the experience quality of terminal services, it is usually necessary not only to deploy the edge computing platform 202 and the edge service server 2022 at a specific site, but also to deploy the same service server 203 on the Internet cloud, so that the terminal device 201 can continue to enjoy Internet service after leaving the coverage of the edge computing platform 202.

[0044] against Figure 2 In the deployment scenario shown in the figure, the related art proposes to use a cloud-based service scheduler to schedule the services deployed in the cloud and the services deployed on the MEC as a whole. The service scheduler makes decisions based on the service access request of the terminal device. Specifically, Figure 3As shown, the service scheduler 304 usually provides an HTTP interface. In the service scheduling request sent by the terminal device 301 to the service scheduler 304, its own location information is represented by modifying the IP address or HTTP header of the service scheduling request. The service scheduler 304 makes scheduling decisions based on the mapping relationship between the pre-configured location information data and the service server, and determines whether the service scheduling request should be provided by the service server 303 deployed in the cloud or the edge service server 3021 deployed on the edge computing platform 302. Then the terminal device 301 sends a service request to the determined service server 303 or edge service server 3021.

[0045] exist Figure 3 In the application scenario shown, the terminal device 301 is required to carry location information in the service scheduling request issued, and a service scheduler 304 that can perform full-network scheduling of service servers including cloud services and edge services needs to be deployed in the cloud. At the same time, it is also necessary to collect and organize the mapping relationship between the geographic location information and the edge service server 3021 and the service server 303 deployed in the cloud, so as to make full-network scheduling decisions based on the location information carried in the service scheduling request of the terminal device 301.

[0046] However, the disadvantages of this implementation are obvious: for Internet services that do not have a full-network service scheduler, the deployment and transformation costs in the edge computing scenario need to be increased; and it is necessary to collect, organize and maintain the mapping relationship between terminal location information data and the full-network (including cloud and edge) business servers, resulting in low management efficiency; at the same time, system upgrades, expansions and maintenance are relatively complex, resulting in higher maintenance costs.

[0047] Based on this, in an application scenario of the embodiment of the present application, Figure 4As shown, an edge user plane functional entity 4021, a DNS proxy module 4022 and an edge service server 4023 are deployed in the edge computing platform 402. As a standard 5G network element, the edge user plane functional entity 4021 has the main function of forwarding network traffic to the Internet or the local edge computing platform 402 according to the instructions of the core network control plane device to realize the local traffic unloading function. As a standard device, the core network control plane device provides an open interface to the outside world so as to interact with other modules through the interface to realize functions such as local traffic unloading. In an embodiment of the present application, the DNS proxy module 4022 on the edge computing platform 402 can use the interface to realize the DNS request sent by the terminal device 401 to the global DNS server to the edge computing platform 402. As a standard network element, the global DNS server provides a standard domain name resolution service. The edge service server 4023 and the service server 403 deployed on the Internet cloud are used to provide normal service services for the service request sent by the terminal device 401 when receiving the service service request.

[0048] In one embodiment of the present application, Figure 4 In the application scenario shown, the DNS request sent by the terminal device 401 to the global DNS server reaches the edge user plane functional entity 4021, and then the edge user plane functional entity 4021 forwards the DNS request to the DNS proxy module 4022, and then the DNS proxy module 4022 forwards the DNS request to the global DNS server. For example, the DNS proxy module 4022 can forward the DNS request to the global DNS server through the edge user plane functional entity 4021, or can directly forward the DNS request to the global DNS server based on the IP address of the global DNS server.

[0049] In one embodiment of the present application, after forwarding the DNS request to the global DNS server, if the DNS proxy module 4022 receives a DNS response returned by the global DNS server, the IP address of the edge service server 4023 is added to the first place in the IP address list contained in the DNS response, and then the modified DNS response is returned to the edge user plane function entity 402, and the edge user plane function entity 402 returns it to the terminal device 401, and then the terminal device 401 can initiate a service request to the edge service server 4023 based on the modified DNS response. This method can achieve lower latency and more efficient service processing without the perception of the service system and the terminal device 401, and since there is no need to modify the service system, it can also reduce the system operation and maintenance costs, which is conducive to improving the system operation and maintenance management efficiency.

[0050] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0051] Figure 5 A flow chart of a communication method based on an edge computing platform according to an embodiment of the present application is shown. The edge computing platform is deployed with an edge user plane function entity, an edge service server and a DNS proxy module. The communication method based on the edge computing platform can be executed by the DNS proxy module. Figure 5 As shown, the communication method based on the edge computing platform includes at least the following steps S510 to S540:

[0052] Step S510, receiving a DNS request from a terminal device forwarded by an edge user plane function entity;

[0053] Step S520, forwarding the DNS request to a DNS server located in the cloud, and receiving a DNS response returned by the DNS server in response to the DNS request;

[0054] Step S530, adding the network address of the edge service server to the first position of the network address list included in the DNS response, to obtain a modified DNS response;

[0055] Step S540: Send the modified DNS response to the edge user plane function entity, so that the edge user plane function entity returns the modified DNS response to the terminal device.

[0056] In one embodiment of the present application, the edge user plane functional entity may only forward a specified DNS request to the DNS proxy module, and the specified DNS request matches the service type processed by the edge service server, that is, if the service requested by the terminal device is deployed in the edge service server, then the DNS request is forwarded to the DNS proxy module, otherwise the edge user plane functional entity may directly forward the DNS request to the DNS server located in the cloud. In this case, before receiving the DNS request from the terminal device forwarded by the edge user plane functional entity, the DNS proxy module may send a first diversion request for the DNS request to the control plane device, and the first diversion request is used to enable the control plane device to send a first diversion strategy for the DNS request to the edge user plane functional entity, and the first diversion strategy is used to instruct the edge user plane functional entity to forward the received specified DNS request to the DNS proxy module.

[0057] In one embodiment of the present application, the edge user plane functional entity may forward all received DNS requests to the DNS proxy module. In this case, if the DNS proxy module determines that the edge service server can process the service request of the terminal device according to the DNS request, then after receiving the DNS response, the network address of the edge service server is added to the first of the network address list contained in the DNS response; if the DNS proxy module determines that the edge service server cannot process the service request of the terminal device according to the DNS request, then after receiving the DNS response, the DNS response is directly sent to the edge user plane functional entity so that the edge user plane functional entity returns the DNS response to the terminal device. In this embodiment, before receiving the DNS request from the terminal device forwarded by the edge user plane functional entity, the DNS proxy module may send a second diversion request for the DNS request to the control plane device, and the second diversion request is used to cause the control plane device to send a second diversion strategy for the DNS request to the edge user plane functional entity, and the second diversion strategy is used to instruct the edge user plane functional entity to forward all received DNS requests to the DNS proxy module.

[0058] In one embodiment of the present application, the process of the DNS proxy module forwarding the DNS request to the DNS server located in the cloud can be to first send the DNS request to the edge user plane functional entity, and then the edge user plane functional entity forwards the DNS request to the DNS server; or the DNS proxy module can send the DNS request directly to the DNS server based on the network address of the DNS server.

[0059] Figure 5 The communication method based on the edge computing platform of the embodiment of the present application is described from the perspective of the DNS proxy module. Figure 6 The technical solution of the embodiment of the present application is described from the perspective of the edge user plane functional entity:

[0060] Figure 6 A flow chart of a communication method based on an edge computing platform according to an embodiment of the present application is shown. The edge computing platform is deployed with an edge user plane functional entity, an edge service server and a DNS proxy module. The communication method based on the edge computing platform can be executed by the edge user plane functional entity. Figure 6 As shown, the communication method based on the edge computing platform includes at least the following steps S610 to S630, which are described in detail as follows:

[0061] In step S610, the DNS request sent by the terminal device is forwarded to the DNS proxy module, so that the DNS proxy module forwards the DNS request to the DNS server located in the cloud.

[0062] In one embodiment of the present application, the edge user plane functional entity may forward a designated DNS request sent by a terminal device to a DNS proxy module, and the designated DNS request matches the service type processed by the edge service server. Specifically, before forwarding the DNS request sent by the terminal device to the DNS proxy module, the edge user plane functional entity may receive a first diversion strategy for the DNS request sent by the control plane device, and the first diversion strategy is generated by the control plane device according to the first diversion request sent by the DNS proxy module, and the first diversion strategy is used to instruct the edge user plane functional entity to forward the received designated DNS request to the DNS proxy module. In this case, if the edge user plane functional entity receives other DNS requests other than the designated DNS request sent by the terminal device, the other DNS requests are forwarded to the DNS server, and then the DNS responses returned by the DNS server for the other DNS requests are received, and the DNS responses returned by the DNS server for the other DNS requests are forwarded to the terminal device.

[0063] In one embodiment of the present application, the edge user plane functional entity may forward all DNS requests sent by the terminal device to the DNS proxy module. Specifically, before forwarding the DNS request sent by the terminal device to the DNS proxy module, the edge user plane functional entity may receive a second diversion strategy for the DNS request sent by the control plane device, the second diversion strategy being generated by the control plane device according to the second diversion request sent by the DNS proxy module, and the second diversion strategy being used to instruct the edge user plane functional entity to forward all received DNS requests to the DNS proxy module.

[0064] In step S620, a modified DNS response sent by the DNS proxy module is received. The modified DNS response is obtained by the DNS proxy module adding the network address of the edge service server to the first position of the network address list included in the DNS response after receiving the DNS response returned by the DNS server.

[0065] In step S630, the modified DNS response is returned to the terminal device, so that the terminal device initiates a business service request to the edge business server based on the modified DNS response.

[0066] In one embodiment of the present application, since the DNS proxy module adds the network address of the edge business server to the first place in the network address list contained in the DNS response after receiving the DNS response returned by the DNS server, the terminal device can preferentially select the network address of the edge business server from the network address list to initiate a business service request.

[0067] The above describes the communication method based on the edge computing platform of the embodiment of the present application from the perspectives of the DNS proxy module and the edge user plane functional entity. Figure 7 The technical solution of the embodiment of the present application is further explained from the perspective of interaction between various entities:

[0068] like Figure 7 As shown, according to an embodiment of the present application, a communication method based on an edge computing platform includes the following steps:

[0069] Step S701: The DNS proxy module sends a traffic diversion request for DNS requests to the control plane device. In one embodiment of the present application, the classification request may be to forward the DNS request matching the service type deployed in the edge service server to the DNS proxy module.

[0070] Step S702, the control plane device sends a DNS request diversion strategy to the edge user plane functional entity. In one embodiment of the present application, if the classification request sent by the DNS proxy module is to forward the DNS request matching the service type deployed in the edge service server to the DNS proxy module, then the diversion strategy is to require the edge user plane functional entity to forward the DNS request matching the service type deployed in the edge service server to the DNS proxy module.

[0071] Step S703: The terminal device sends a DNS request to the edge user plane function entity.

[0072] In one embodiment of the present application, the DNS request may be a DNS request based on a standard DNS protocol, or may be a DNS request using an HTTP protocol (ie, using an HTTP DNS service scheduling method).

[0073] Step S704: the edge user plane functional entity diverts the DNS request to the DNS proxy module. In this embodiment, assuming that the DNS request sent by the terminal device matches the service type deployed in the edge service server, the edge user plane functional entity diverts the DNS request to the DNS proxy module.

[0074] Step S705: The DNS proxy module forwards the DNS request to the global DNS server.

[0075] Step S706: The global DNS server returns a DNS response, which includes a list of IP addresses assigned by the global DNS server.

[0076] Step S707: The DNS proxy module modifies the DNS response and sends the modified DNS response to the edge user plane functional entity. Specifically, the DNS proxy module can add the IP address of the edge service server deployed on the edge computing platform to the first of the IP address list in the DNS response, and then send it to the edge user plane functional entity.

[0077] Step S708: The edge user plane function entity forwards the modified DNS response to the terminal device.

[0078] Step S709: After receiving the modified DNS response, the terminal device initiates a business service request to the edge business server according to the modified DNS response.

[0079] It should be noted that in Figure 7 In the illustrated embodiment, the diversion request for the DNS request sent by the DNS proxy module to the control plane device is a request to forward the DNS request that matches the service type deployed in the edge service server to the DNS proxy module. In this case, if the DNS request sent by the terminal device does not match the service type deployed in the edge service server, that is, the edge service server does not deploy the service requested by the terminal device, then the edge user plane functional entity can send the DNS request directly to the global DNS server, and send the DNS response returned by the global DNS server to the terminal device.

[0080] In other embodiments of the present application, the diversion request for the DNS request sent by the DNS proxy module to the control plane device may also be a request to forward all DNS requests sent by the terminal device to the DNS proxy module. In this case, the DNS proxy module needs to determine whether the DNS request matches the service type deployed in the edge service server. If it matches, the DNS response returned by the global DNS server needs to be modified; if it does not match, the DNS proxy module can directly forward the DNS response returned by the global DNS server to the edge user plane function entity after receiving the DNS response returned by the global DNS server, and the edge user plane function entity forwards it to the terminal device.
