Detailed ways

It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

The present invention provides a service method of a mobile base station CDN system.

Referring to FIG. 1 , it is a flowchart of a first embodiment of a service method for a CDN system of a mobile base station according to the present invention.

In the first embodiment, the service method of the mobile base station CDN system includes:

Step S10, receiving the remote user dial-up authentication RADIUS request sent by the remote terminal, and the HTTP request;

Step S20, according to the received RADIUS request and HTTP request sent by the remote terminal, the CDN system of the mobile base station provides the remote terminal with a service corresponding to the preset rule.

The base station is the access point for the user to access the Internet. In this embodiment, a CDN server is deployed in the nodeB of the base station, and the CDN server can directly obtain the RADIUS (Remote Authentication DialIn User Service) sent by the user to the base station. ) requests and HTTP (Hyper Text Transfer Protocol, Hyper Text Transfer Protocol) requests, a general server is set up on the basis of multiple base station CDNs, and the obtained requests are parsed and processed.

Referring to Figure 2, step S20 may include the following refinement steps:

Step S21, when receiving a remote user dial-up authentication RADIUS request sent by a remote terminal, parse the RADIUS request to obtain and associate the user ID and the base station ID.

When a user uses a terminal such as a mobile phone or a tablet to access the Internet through mobile traffic, and the user enables the mobile traffic-based Internet service provided by the operator on the terminal, the terminal will send a remote user dial-up authentication request to the base station to access the network, and the above RADIUS request , the RADIUS request contains the user ID and the base station ID, and associates the user ID with the base station ID, where the user ID can include the mobile phone number, the user's IP address, or the identification information of the user terminal, etc. The base station ID can be the base station ID or The specific location of the base station and other information. When receiving the RADIUS request sent by the remote terminal, the RADIUS request is parsed to obtain and associate the user ID and base station ID contained in the request, such as the obtained mobile phone number, user IP address or user terminal identification information, etc. The user identification information is associated with the base station ID.

Step S22, when receiving the HTTP request sent by the remote terminal, obtain the access information and the user ID corresponding to the HTTP request, and obtain the base station ID associated with the user ID.

Step S23: Update the acquired access statistical information corresponding to the base station identifier according to the access information, where the access information includes an access address.

After the remote terminal successfully implements the remote dial-up authentication, the user accesses the website by sending an HTTP request. After receiving the HTTP request sent by the above-mentioned remote terminal, the HTTP request is intercepted, and the URL of the HTTP request accessed by the user is obtained from it (Uniform Resource Locator (Uniform Resource Locator), domain information of the URL accessed by the user, access information such as access time, and user ID, and obtain the base station ID associated with the user ID. Since the URLs accessed by each user may be duplicated, for example , there is a situation where multiple users access the same URL. Therefore, after obtaining the above access information, update the access statistics corresponding to the pre-established base station identifier, because the received HTTP request may be for different base stations, so It is necessary to separately count the access requests of each base station, including the number of times the URL has been accessed and the access time, etc. Therefore, each time an HTTP request is received, the number of accesses to the URL corresponding to the HTTP request is updated, and the access times Time and other information, the access popularity of a URL address can be obtained according to the information, for example, the number of times a URL address is accessed within a certain period of time.

Step S24, when the access statistical information matches a preset rule, the mobile base station CDN system provides the remote terminal with a service corresponding to the preset rule.

Preset rules can be set in advance, for example, to set the VIP mobile phone number, or when the number of visits to a URL reaches a certain number of times, or for users who visit a specific base station, and configure the corresponding targeting services for the preset rules, such as targeting Acceleration, targeted push, etc. When the updated access statistics match the configured preset rules, provide services corresponding to the preset rules, such as cache acceleration, advertisement push, bandwidth control, redirection, etc., to the remote terminal that sends the above-mentioned RADIUS request and HTTP request.

The above access statistics reflect the user's access hotspots, such as statistics of hotspot videos and popular websites in a specific base station area, and then targeted acceleration for TOP100 website resources, combined with TOP100 website visits and videos, through big data calculation , you can push the corresponding recommendation information for a specific user of a base station for Internet access, such as a base station in a commercial street, collect the corresponding information through CDN, and push the link of a business that is holding promotional activities near the base station, such as a base station in a school dormitory , you can push relevant advertising information by collecting videos that students have watched hotly in the recent period. It can not only optimize the user experience, but also fully grasp the behavioral characteristics of users, so as to achieve refined traffic management in the true sense.

In the service method of the mobile base station CDN system proposed in this embodiment, a CDN server is set up at the base station, and preset rules are set in advance, and when a RADIUS request sent by a remote terminal is received, the request is parsed to obtain and associate the user ID with the base station ID. , when the remote terminal sends an HTTP request to access the network, obtain the access information and user ID corresponding to the HTTP request, obtain the base station ID associated with the user ID, and update the access statistical information corresponding to the base station ID, and determine whether the access statistical information conforms to the The preset rules match. If they match, the remote terminal will be provided with services corresponding to the preset rules, such as cache acceleration, directional push, etc., which solves the technical problem that the existing CDN cannot provide directional services based on the user access information of a specific base station. .

Referring to FIG. 3 , based on the first embodiment of the service method of the mobile base station CDN system of the present invention, a second embodiment of the service method of the mobile base station CDN system of the present invention is proposed. In this embodiment, step S24 includes the following refinement steps:

Step S241, when the access statistical information conforms to the configured preset rule and the service corresponding to the preset rule is cache acceleration, acquire the content corresponding to the HTTP request from the cache area.

Step S242, when the content corresponding to the HTTP request is obtained from the cache area, respond to the HTTP request and send the content corresponding to the HTTP request in the cache area to the remote terminal corresponding to the user ID.

When the service corresponding to the preconfigured preset rule is to provide cache acceleration to the remote terminal that sends the above-mentioned RADIUS request and HTTP request and satisfies the preset rule, the content corresponding to the HTTP request obtained from the cache area is sent to the remote terminal terminal.

Further, after step S241, step S24 further includes:

When the content corresponding to the HTTP request cannot be obtained from the cache area, download the content corresponding to the HTTP request from the source server corresponding to the HTTP request and respond to the remote terminal; save the content corresponding to the HTTP request to the buffer area.

It is understandable that when a URL address is accessed for the first time, even if the access meets the requirements, the content corresponding to the HTTP request has not been cached in the cache area. At this time, the corresponding HTTP request is obtained from the source server corresponding to the HTTP request. It responds to the remote terminal that sends the HTTP request, and saves the acquired content to the cache area. When a request that conforms to the preset rules is received again, the corresponding remote terminal is provided with a cache acceleration service.

Further, if the user ID and access statistics do not conform to the configured preset rules, the HTTP request is directly transparently proxyed to the destination address, and no processing is performed on the request.

For example, a user who surfs the Internet near a certain base station is provided with a cache acceleration service. Suppose the preset rule configured is that the number of visits to the URL of video A of the Youku website reaches 100 times, and the corresponding service is cache acceleration. When the user accesses the Internet through the base station, first parse the RADIUS request sent by the user's terminal, and parse the request to obtain the user ID and base station ID, the user accesses the video A of the Youku website, obtains the access information such as the URL address of the video A, and updates the URL The number of visits to the address. If the number of visits reaches 100, the content corresponding to the HTTP request will be cached. The statistics of the number of visits can be the visit requests sent by different users. When the same HTTP request is subsequently received, it is an HTTP request. The corresponding remote terminal provides the cache acceleration service, that is, the content corresponding to the request in the cache can be directly sent to the remote terminal without having to request the corresponding content from the origin server. The user brings a better online experience, and at the same time realizes the value-added traffic. The above is just a simple example. In practical applications, diversified preset rules can be created according to the needs of different operators to achieve a more refined service experience.

In other embodiments, it may also be other targeted services, such as targeted push and so on. When the access statistical information conforms to the configured preset rule and the service corresponding to the preset rule is advertisement push, push the configured advertisement information to the remote terminal that sends the HTTP request that conforms to the preset rule.

Further, the method also includes the following steps:

The preset rules are updated according to the updated access statistics.

Update preset rules according to access statistics. For example, when popular URLs change, preset rules can be updated according to the changed information; or operators can set preset rules according to their own needs, such as providing targeted services for specific VIP users , or provide targeting services for users in a specific location, or provide targeting services for users who visit a certain URL.

The present invention also proposes a CDN system of a mobile base station.

Referring to FIG. 4 , it is a schematic diagram of functional modules of the first embodiment of the CDN system of the mobile base station according to the present invention.

The base station is the access point for the user to access the Internet. In this embodiment, a CDN server is deployed in the nodeB of the base station, and the CDN server can directly obtain the RADIUS (Remote Authentication DialIn User Service) sent by the user to the base station. ) request and HTTP (Hyper Text Transfer Protocol, Hyper Text Transfer Protocol) request, set up a general server on the basis of multiple base station CDNs, as a mobile base station CDN system, parse and process the obtained requests.

Further, as shown in FIG. 5 , the service control module 20 may include the following units:

The parsing unit 21 is configured to parse the RADIUS request to obtain and associate the user ID and the base station ID when receiving the remote user dial-up authentication RADIUS request sent by the remote terminal.

When a user uses a terminal such as a mobile phone or a tablet to access the Internet through mobile traffic, and the user enables the mobile traffic-based Internet service provided by the operator on the terminal, the terminal will send a remote user dial-up authentication request to the base station to access the network, and the above RADIUS request , the RADIUS request contains the user ID and the base station ID, and associates the user ID with the base station ID, where the user ID can include the mobile phone number, the user's IP address, or the identification information of the user terminal, etc. The base station ID can be the base station ID or The specific location of the base station and other information. When receiving the RADIUS request sent by the remote terminal, the parsing unit 21 parses the RADIUS request, and obtains and associates the user ID and base station ID contained therein, such as the obtained mobile phone number, the user's IP address, or the user terminal's ID. User identification information such as identification information is associated with the base station ID.

The obtaining unit 22 is configured to obtain access information and a user ID corresponding to the HTTP request when receiving the HTTP request sent by the remote terminal, and obtain the base station ID associated with the user ID.

The updating unit 23 is configured to update the acquired access statistics information corresponding to the base station identifier according to the access information, wherein the access information includes an access address.

After the remote terminal successfully implements the remote dial-up authentication, the user accesses the website by sending an HTTP request, and after receiving the HTTP request sent by the above-mentioned remote terminal, the obtaining unit 22 intercepts the HTTP request, and obtains the information of the HTTP request accessed by the user. URL (Uniform Resource Locator, Uniform Resource Locator), the domain information of the URL accessed by the user, and access information such as access time, as well as the user ID, and obtain the base station ID associated with the user ID, since the URL accessed by each user may exist Repeat, for example, there is a situation where multiple users access the same URL. Therefore, after obtaining the above access information, update the access statistics corresponding to the pre-established base station identifier, because the received HTTP request may be for different base stations. , so it is necessary to separately count the access requests of each base station, including the number of times the URL has been accessed, and the access time, etc. Therefore, each time an HTTP request is received, the obtaining unit 22 updates the URL corresponding to the HTTP request. Information such as the number of visits and the visit time can be used to obtain the visit popularity of a URL address, for example, the number of times a URL address is visited within a certain period of time.

The execution unit 24 is configured to provide the remote terminal with a service corresponding to the preset rule when the access statistical information matches a preset rule.

Preset rules can be set in advance, for example, to set the VIP mobile phone number, or when the number of visits to a URL reaches a certain number of times, or for users who visit a specific base station, and configure the corresponding targeting services for the preset rules, such as targeting Acceleration, targeted push, etc. When the acquired user ID and the updated access statistics conform to the configured preset rules, the execution unit 24 provides services corresponding to the preset rules, such as cache acceleration, advertisement push, for the remote terminal that sends the above-mentioned RADIUS request and HTTP request , bandwidth control, redirection, etc.

The above access statistics reflect the user's access hotspots, such as statistics of hotspot videos and popular websites in a specific base station area, and then targeted acceleration for TOP100 website resources, combined with TOP100 website visits and videos, through big data calculation , pushes corresponding recommendation information for a specific user of a base station for Internet access, such as a base station in a commercial street, collects corresponding information through CDN, and the execution unit 24 can push the link of a business that is holding promotional activities near the base station, such as in a school dormitory The base station, the execution unit 24 can push relevant advertisement information by collecting videos watched by students in a recent period of time. It can not only optimize the user experience, but also fully grasp the behavioral characteristics of users, so as to achieve refined traffic management in the true sense.

In the mobile base station CDN system proposed in this embodiment, a CDN server is set at the base station, and preset rules are set in advance, and when a RADIUS request sent by a remote terminal is received, the request is parsed to obtain and associate the user ID with the base station ID. When the terminal sends an HTTP request to access the network, it obtains the access information and user ID corresponding to the HTTP request, obtains the base station ID associated with the user ID, and updates the access statistics corresponding to the base station ID, and determines whether the access statistics conform to the preset rules. If it matches, the remote terminal will be provided with services corresponding to the preset rules, such as cache acceleration, directional push, etc., which solves the technical problem that the existing CDN cannot provide directional services based on user access information of a specific base station.

Referring to FIG. 6 , based on the first embodiment of the mobile base station CDN system of the present invention, a second embodiment of the mobile base station CDN system of the present invention is proposed. In this embodiment, the execution unit 24 includes the following subunits:

The cache obtaining subunit 241 is configured to obtain the content corresponding to the HTTP request from the cache area when the access statistical information conforms to the configured preset rule and the service corresponding to the preset rule is cache acceleration.

The cache acceleration subunit 242 is configured to respond to the HTTP request and send the content corresponding to the HTTP request in the cache area to the user ID when the content corresponding to the HTTP request is obtained from the cache area the corresponding remote terminal.

When the service corresponding to the preconfigured preset rule is to provide cache acceleration to the remote terminal that sends the above-mentioned RADIUS request and HTTP request and satisfies the preset rule, the cache acquisition subunit 241 acquires the content corresponding to the HTTP request from the cache area, and caches the content corresponding to the HTTP request. The acceleration subunit 242 sends it to the remote terminal.

Further, the cache acquisition subunit 241 is further configured to download the content corresponding to the HTTP request from the source server corresponding to the HTTP request and respond to the HTTP request when the content corresponding to the HTTP request cannot be obtained from the cache area. a remote terminal; and saving the content corresponding to the HTTP request to the cache area.

It is understandable that when a URL address is accessed for the first time, even if the access meets the requirements, the content corresponding to the HTTP request has not been cached in the cache area. At this time, the corresponding HTTP request is obtained from the source server corresponding to the HTTP request. It responds to the remote terminal that sends the HTTP request, and saves the acquired content to the cache area. When a request that conforms to the preset rules is received again, the corresponding remote terminal is provided with a cache acceleration service.

Further, if the user identification and the access statistical information do not conform to the configured preset rules, the execution unit 24 directly transparently proxies the HTTP request to the destination address, and does not perform any processing on the request.

For example, a user who surfs the Internet near a certain base station is provided with a cache acceleration service. Suppose the preset rule configured is that the number of visits to the URL of video A of the Youku website reaches 100 times, and the corresponding service is cache acceleration. When the user accesses the Internet through the base station, the parsing unit 21 first parses the RADIUS request sent by the user's terminal, and parses the request to obtain the user ID and the base station ID, the user accesses the video A of the Youku website, and the obtaining unit 22 obtains the URL address of the video A and other accesses information, and update the number of visits of the URL address. If the number of visits reaches 100, the cache acquisition subunit 241 caches the content corresponding to the HTTP request. The statistics of the number of visits may be the visit requests sent by different users. When receiving the same HTTP request, the cache acceleration subunit 242 provides a cache acceleration service for the remote terminal corresponding to the HTTP request, that is, the content corresponding to the request in the cache can be directly sent to the remote terminal without having to request the corresponding content from the origin server. , for the remote terminal, it speeds up the response time of HTTP requests, brings users a better online experience, and realizes the value-added of traffic. The above is just a simple example. In practical applications, diversified preset rules can be created according to the needs of different operators to achieve a more refined service experience.

In other embodiments, it may also be other targeted services, such as targeted push and so on. The execution unit 24 may further include a directional push sub-unit, configured to send a message that meets the preset rules of the configuration when the user identifier and the access statistical information conform to the preset rules, and the service corresponding to the preset rules is advertisement push. The remote terminal of the HTTP request of the preset rule pushes the configured advertisement information.

Further, the system further includes a configuration module for updating the preset rules according to the updated access statistics.

The configuration module updates the preset rules according to the access statistics. For example, when the popular website changes, the preset rules can be updated according to the changed information; or the operator can set the preset rules according to their own needs, such as providing specific VIP users. Orientation services, or provide targeted services for users in a specific location, or provide targeted services for users who visit a certain URL.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention.
