Description

Communication processing method and device, computer readable medium and electronic equipment

Technical Field

The present application relates to the field of computer and communication technologies, and in particular, to a communication processing method and apparatus, a computer-readable medium, and an electronic device.

Background

With the popularization of mobile intelligent terminals, the increasing mobile data services bring huge traffic to mobile networks. Therefore, Network congestion is reduced by adopting a Content Delivery Network (CDN), and corresponding access speed and hit rate of a user are improved.

In the existing CDN deployment scheme, a service server may be deployed at nodes in the country, or in the provincial level, or in the key city level, and there are many users that can be served, and there are usually many stored contents and service contents that can be provided. However, due to the deployment scenario of the MEC (Multi-Access Edge Computing) service server, the service content that can be provided by the MEC service server is generally less, so the hit rate of the service request sent by the terminal device in a single MEC service server is lower, and further, more response delay is brought.

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 may include: a terminal device 101 (e.g., a smart phone, a tablet computer, a portable computer, a desktop computer, etc.); a base station 102; a routing unit 103 and an MEC server (e.g., MEC servers 104a, … …, MEC server 104n, etc.) deployed in the mobile network; a dispatch server 105 and a CDN server 106 deployed in the internet public network. The routing unit 103 is configured to provide a routing service between the base station 102 and the internet public network, for example, the routing unit 103 may be a core network device in a mobile network, or may be a set of the core network device and an MEC server.

It should be understood that the number of terminal devices, base stations and various servers in fig. 1 are merely illustrative. There may be any number of terminal devices, base stations and corresponding individual servers, as desired for implementation.

In one embodiment of the present application, the terminal device 101 may send a DNS query request to the DNS server through the base station 102, so that the DNS server returns DNS response information. The DNS server may be deployed in a mobile network or an internet public network, and if the DNS server is deployed in the internet public network, the base station 102 may send the DNS query request to the DNS server through the routing unit 103.

In an embodiment of the present application, after acquiring the DNS response information, the terminal device 101 may acquire the address information of the scheduling server 105 from the DNS response information, and then send an access scheduling request to the scheduling server 105, where the access scheduling request may be sent to the scheduling server 105 through the base station 102 and the routing unit 103, and the scheduling server 105 may return the MEC server set allocated to the terminal device 101.

In an embodiment of the present application, after acquiring the MEC server set returned by the scheduling server 105, the terminal device 101 may select one MEC server from the MEC server set to initiate a service access request, for example, select an MEC server with the largest service content provided or select an MEC server with the lowest communication delay. Assuming that the MEC server 104a is selected by the terminal device 101, the terminal device 101 may initiate a service access request to the MEC server 104a, and if the MEC server 104a can respond to the service access request, return service response content to the terminal device 101. If the MEC server 104a cannot respond to the service access request, that is, the terminal device 101 cannot acquire the service response content from the MEC server 104a, another MEC server whose difference between the provided service content and the service content provided by the MEC server 104a is greater than the set value may be selected from the MEC server set allocated by the scheduling server 105 to initiate the service access request, so that the hit rate of the service access request may be increased to a certain extent, the response delay of the service access request may be reduced, and the user experience may be improved.

In an embodiment of the present application, if the terminal device 101 cannot obtain the service response content from the MEC server set allocated by the scheduling server 105, a service access request may be initiated to the CDN server 106 through the base station 102 and the routing unit 103 to ensure that the terminal device 101 can obtain the service response content.

The implementation details of the technical solution of the embodiment of the present application are set forth in detail below:

fig. 2 shows a flowchart of a communication processing method according to an embodiment of the present application, which may be performed by a terminal device, such as the terminal device 101 shown in fig. 1. 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 set of service servers allocated by the scheduling server is obtained.

In an embodiment of the present application, the service server set allocated by the scheduling server may be an MEC service server set, where the MEC service server set includes a plurality of MEC service servers.

In one embodiment of the present application, the terminal device may send an access scheduling request to the scheduling server, and then the scheduling server allocates a service server set to the terminal device, and the terminal device may receive the service server set returned by the scheduling server according to the access scheduling request.

In an embodiment of the present application, before sending the access scheduling request to the scheduling server, the terminal device may send a DNS query request to the DNS server, then receive DNS response information returned by the DNS server according to the DNS query request, obtain address information of the scheduling server based on the DNS response information, and then send the access scheduling request to the scheduling server based on the address information of the scheduling server.

In an embodiment of the present application, the service server set acquired by the terminal device may include addresses of the service servers allocated by the scheduling server and service content information provided by the service servers, and the terminal device may calculate a difference between the service contents provided by the service servers according to the address information. For example, the service server address included in the service server set is: 10.17.81.67, 10.17.82.92, and 10.17.83.45. The service content information provided by the service server address 10.17.81.67 may be a _0 and a _ 1; the service content information provided by the service server address 10.17.82.92 may be a _0 and a _ 2; the service content information provided by the service server address 10.17.83.45 may be a _0, a _3, and a _ 4.

In an embodiment of the present application, the service server set acquired by the terminal device may include addresses of the service servers allocated by the scheduling server, and differences between service contents provided by the service servers. That is, in this embodiment, the scheduling server may calculate the difference between the service contents provided by the respective service servers.

Continuing to refer to fig. 2, in step S220, a first service server is selected from the service server set to initiate a service access request.

In an embodiment of the present application, the terminal device may select, from the service server set, a service server with the largest service content provided as a first service server to initiate a service access request, so as to improve a hit rate of the service access request.

In an embodiment of the present application, the terminal device may select a service server with the lowest communication delay from the service server set as the first service server to initiate the service access request, so as to improve the service access efficiency. The communication delay may be a communication delay between the terminal device and the service server, and may include a one-way or round-trip delay, which is not limited herein.

In step S230, if the service response content for the service access request is not acquired from the first service server, a second service server, in which a difference between the provided service content and the service content provided by the first service server is greater than a set value, is selected from the set of service servers.

In an embodiment of the present application, the terminal device may determine that the service response content for the service access request is not acquired from the first service server when receiving a redirection message for the service access request returned by the first service server and the redirection message includes a specified network address. Alternatively, the specified network address may be a previously agreed-upon network address.

In an embodiment of the present application, the terminal device may also determine that no service response content for the service access request is obtained from the first service server when receiving a redirection message for the service access request returned by the first service server, where the redirection message includes indication information for indicating that another service server is preferentially selected. Alternatively, the indication information may be set in a header of an HTTP (HyperText Transfer Protocol) message and/or an HTTP message body.

In an embodiment of the present application, the terminal device may further determine that the service response content for the service access request is not acquired from the first service server when the response information for the service access request returned by the first service server is not received within a predetermined time period.

In an embodiment of the present application, a difference between service content provided by a first service server and service content provided by each other service server in a service server set may be calculated to obtain a difference value corresponding to each service server, and then a service server with the largest corresponding difference value is selected as a second service server, so as to improve a hit rate of a service access request.

In an embodiment of the present application, a difference between service content provided by the first service server and service content provided by each other service server in the service server set may also be calculated to obtain a difference value corresponding to each service server, and then a service server with the lowest communication delay is selected from the service servers with the corresponding difference values larger than a set value as the second service server, so as to improve service access efficiency on the premise of improving the hit rate of the service access request.

Continuing to refer to fig. 2, in step S240, the service access request is sent to the second service server.

In an embodiment of the present application, after sending a service access request to a second service server, if a service response content for the service access request is not obtained from the second service server, according to a descending order of a difference between a provided service content and a service content provided by a first service server, sequentially selecting other service servers from a set of service servers to send the service access request until the service response content is obtained.

For example, if the service server set includes 5 service servers (i.e., the service server 1, the service server 2, the service server 3, the service server 4, and the service server 5), and the service server selected for the first time is the service server 1, the content difference between the service server 1 and each of the other service servers may be calculated in advance, and if the content difference is sequentially the service server 2, the service server 3, the service server 4, and the service server 5 from large to small, when the terminal device cannot obtain the service response content from the service server 1, the service server 2 may be selected to initiate a service access request, when the terminal device cannot obtain the service response content from the service server 2, the service server 3 may be selected to initiate a service access request, and the service access request is sequentially executed until the service response content is obtained.

Alternatively, the difference between the other service servers in the service server set and the first service server may be calculated in real time each time the service response content cannot be acquired from the service server. For example, if the service server set includes 5 service servers (i.e., the service server 1, the service server 2, the service server 3, the service server 4, and the service server 5), and the service server selected for the first time is the service server 1, when the terminal device cannot obtain the service response content from the service server 1, the content difference between the service server 1 and each of the other service servers may be calculated, and then the service server 2 with the largest content difference is selected to initiate a service access request; if the terminal device cannot acquire the service response content from the service server 2, the content difference between the service server 1 and each of the other service servers except the service server 2 may be calculated, and then the service server 3 with the largest content difference is selected to initiate a service access request, and the service access requests are sequentially executed until the service response content is acquired.

In another embodiment of the present application, after sending the service access request to the second service server, if the service response content for the service access request is not obtained from the second service server, according to the sequence of the difference between the provided service content and the service content provided by all the accessed service servers from large to small, other service servers are sequentially selected from the service server set to send the service access request until the service response content is obtained.

For example, if the service server set includes 5 service servers (i.e., the service server 1, the service server 2, the service server 3, the service server 4, and the service server 5), and the service server selected for the first time is the service server 1, the content difference between the service server 1 and each of the other service servers may be calculated in advance, and then the service server selected for the second time is determined to be the service server 2 based on the content difference; then, continuously calculating the content difference between the union of the service contents provided by the service server 1 and the service server 2 and other service servers to determine the service server selected for the third time as a service server 3; and then continuing to calculate the content difference degree between the union of the service contents provided by the service server 1, the service server 2 and the service server 3 and other service servers to determine the service server selected for the fourth time as the service server 4. Based on this, when the terminal device cannot obtain the service response content from the service server 1, the service server 2 may be selected to initiate the service access request, and when the terminal device cannot obtain the service response content from the service server 2, the service server 3 may be selected to initiate the service access request, and the service access request is sequentially executed until the service response content is obtained. It should be noted that if there is no difference between the contents provided by the other service servers and the service server 1, when the terminal device cannot obtain the service response content from the service server 1, the terminal device may directly send the service access request to the CDN server.

Alternatively, the difference between other service servers in the service server set and the accessed service server can be calculated in real time each time the service response content cannot be acquired from the service server. For example, if the service server set includes 5 service servers (i.e., the service server 1, the service server 2, the service server 3, the service server 4, and the service server 5), and the service server selected for the first time is the service server 1, when the terminal device cannot obtain the service response content from the service server 1, the content difference between the service server 1 and each of the other service servers may be calculated, and then the service server 2 with the largest content difference is selected to initiate a service access request; if the terminal device cannot acquire the service response content from the service server 2, the content difference between the content union provided by the service server 1 and the service server 2 and each other service server may be calculated, and then the service server 3 with the largest content difference is selected to initiate a service access request, and the service access request is executed in sequence until the service response content is acquired.

In an embodiment of the present application, based on the technical solution of the foregoing embodiment, if service access requests are all sent to a predetermined number of service servers in a service server set and no service response content is obtained, the service access requests are sent to a content delivery network CDN server. The technical scheme of the embodiment can ensure that the terminal equipment can acquire the service response content from the CDN server under the condition that the service response content cannot be acquired from the service server set. The predetermined number of service servers may be the number of all service servers in the service server set, or the number of part of service servers in the service server set.

The technical scheme of the embodiment shown in fig. 2 enables the terminal device to respond to the service access request by selecting the service server with a larger difference in the contents of the provided services, thereby facilitating the improvement of the hit rate of the service access request, reducing the response delay of the service access request, and improving the user experience.

Fig. 3 shows a flowchart of a communication processing method according to an embodiment of the present application, which may be performed by a service server, which may be the MEC server shown in fig. 1. Referring to fig. 3, the communication processing method at least includes steps S310 to S330, which are described in detail as follows:

in step S310, a service access request sent by the terminal device is received.

In one embodiment of the present application, the terminal device may select one service server from the service server set allocated by the scheduling server to send the service access request. The specific selection strategy can refer to the technical scheme of the previous embodiment.

In step S320, it is determined whether the service server has the capability of responding to the service access request according to the service content provided by the service server.

In one embodiment of the present application, if the service content to be obtained by the service access request matches the service content provided by the service server, it is determined that the service server has the ability to respond to the service access request; otherwise, it may be determined that the service server is unable to respond to the service access request.

In step S330, if it is determined that the service server cannot respond to the service access request, returning redirection information to the terminal device to instruct the terminal device to select another service server having a difference between the provided service content and the service content provided by the service server that is greater than a set value to initiate a service access request.

In an embodiment of the present application, the redirection message returned by the service server may include a specified network address, such as a pre-agreed network address, to instruct the terminal device to select another service server having a content difference greater than a set value to initiate a service access request.

In an embodiment of the present application, the redirection message returned by the service server may further include indication information to indicate the terminal device to select another service server having a content difference greater than a set value to initiate a service access request. The indication information can be explicit indication information and can be set in the header of the HTTP message or can also be set in the body part of the HTTP message; the indication information may also be implicit indication information, for example, the indication information may be an IP address (e.g. 10.0.0.0) or a port number agreed in advance, and when the terminal device detects the agreed IP address or port number from the redirection message, it may be determined that another service server with a content difference greater than a set value needs to be selected to initiate a service access request.

The process of the terminal device selecting another service server to initiate a service access request refers to the technical solution of the foregoing embodiment, and is not described again.

The communication processing method in the embodiment of the present application is described above from the perspective of the terminal device and the service server, and details of implementation of the communication processing scheme in the embodiment of the present application are described below with reference to fig. 4, taking the service server as an MEC server as an example:

referring to fig. 4, a communication processing method according to an embodiment of the present application includes the following steps S401 to S406, which are described in detail as follows:

in step S401, the user equipment initiates an access scheduling request to the scheduling server.

It should be noted that: before initiating an access scheduling request to the scheduling server, the user equipment may also initiate a DNS query request to the DNS server to obtain information such as a network address of the scheduling server according to DNS response information returned by the DNS server. The user equipment needs to initiate an access scheduling request to the scheduling server through the base station.

In step S402, the scheduling server returns the set of service servers to the user equipment.

In one embodiment of the present application, the set of service servers returned by the scheduling server may include addresses of the respective service servers. The service server is used for the user equipment to obtain services, such as video services, game services, application downloading services and the like. Optionally, the service server set includes at least one or more MEC service server addresses (e.g., IP address sets) potentially available to the user equipment, and both the one or more MEC service servers potentially available to the user equipment and the user equipment are routable bidirectionally, that is, the user equipment may send messages to the one or more MEC service servers potentially available to the user equipment, and may also receive messages sent by the one or more MEC service servers potentially available to the user equipment.

In one embodiment of the present application, the set of traffic servers may contain one or more IP addresses, such as 10.17.81.67, 10.17.82.92, and 10.17.83.45. The IP address may be IPv4(Internet Protocol version 4) or IPv6(Internet Protocol version 6, Internet Protocol version 6).

In one embodiment of the present application, the service server set may include one or more IP addresses and a mapped content set, and the user equipment may store the service server set until successfully acquiring a service or redirecting to a CDN service server. In particular, the content set may be used to instruct the service server to provide the content composition of the service. Taking a video service as an example, the video content may be divided into a content set { a _0, a _1, …, a _ N }, where each element represents a part of the service content, and different elements may be completely different or partially the same. For example, in the mapping relationship shown in fig. 5, the content set of the service server corresponding to the IP address 10.17.81.67 may be { a _0, a _1 }; the content set of the service server corresponding to the IP address 10.17.82.92 may be { a _0, a _2 }; the content set of the service server corresponding to the IP address 10.17.83.45 may be { a _0, a _3, a _4 }; the content of the content set elements a _0, a _1, a _2, a _3, and a _4 may be different.

In step S403, the user equipment initiates a service access request to the first MEC server.

In an embodiment of the present application, the user equipment may first select a service server of the first MEC to initiate a service request according to a service server selection algorithm. The service server selection algorithm may be to preferentially select an MEC service server containing the most elements of the content set for access when the user equipment has potential access to multiple optional MEC service servers, such as an MEC service server with IP address 10.17.83.45, and the MEC service server may be selected to initiate a service request because its content set contains the most elements. Or, the MEC service server with the lowest time delay may be selected for access, and in addition, the MEC service server accessed for the first time may be selected in other manners.

In step S404, the user equipment misses a desired service in the first MEC service server. For example, the first MEC service server does not store the video content that the user wishes to view.

Specifically, in a first possible example, the first MEC service server may return a redirection message to the user equipment, where the redirection message carries a special and pre-agreed IP address (e.g. 10.0.0.0) to indicate that, after receiving the special IP address, the user equipment may not directly connect to the service server to which the IP address points, but execute a content set difference algorithm, and access the MEC service server to which the content set difference algorithm points according to a result of the algorithm. In addition, the redirection message may also carry a CDN service server or other service server address that can be returned to the source.

In a second possible example, the first MEC service server may return a redirection message to the user equipment, and at the same time, the HTTP message header and/or the HTTP message body carries indication information to indicate that, when the user reselects an MEC service server to be accessed in a subsequent step, the MEC service server address indicated by the redirection message may not be preferentially connected, but a content set difference algorithm is executed and the MEC service server pointed to according to an algorithm result is accessed.

In step S405, the user equipment sends a service request to the service server of the second MEC. When the MEC service server is selected, the user equipment may execute a content set difference algorithm, that is, according to the service server set (including at least the IP address and the content set of the service server) received in step S402, select an MEC service server with a content set that is the most different from the content set of the first MEC service server in step S403 as a second MEC service server to initiate the service request.

Specifically, for example, the content set of the first MEC service server is { a _0, a _1}, and the content sets of MEC service servers potentially available to the user equipment after the miss are { a _0, a _2} and { a _0, a _3, a _4}, respectively, then in the content set difference algorithm, the user equipment may select, as the second MEC service server, the MEC service server corresponding to the content set { a _0, a _3, a _4} with the largest difference from the content set { a _0, a _1}, so as to initiate the service request, so as to improve the service hit rate.

In step S406, the second MEC service server returns a service access response, and the user equipment obtains the desired service content.

It should be noted that, if the user equipment does not obtain the desired service from the service server of the second MEC, other MEC service servers may be sequentially selected and access is attempted according to the difference of the content sets according to the content set difference algorithm (the specific selection process may refer to the technical solution of the foregoing embodiment, and is not described again); if the miss continues and after a certain number of attempts (e.g., N times, where N is a natural number greater than or equal to 1) is reached, or there is no retriable MEC service server, the scheduling request of the user equipment may be sourced back to the CDN service server, so as to maintain the disaster tolerance capability and control the service access delay not to be too long.

According to the technical scheme of the embodiment of the application, the feedback sent by the scheduling server carries the information such as the IP address and the content set, so that when the service access request is not hit, the user equipment can respond to the service access request by selecting other MEC service servers with larger service content differences, the hit rate of the service access request is improved, the response delay of the service access request is reduced, and the user experience is improved.
