Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a service method of a CDN system of a mobile base station.
Fig. 1 is a flowchart illustrating a service method of a CDN system of a mobile base station according to a first embodiment of the present invention.
In a first embodiment, a service method of the CDN system includes:
step S10, receiving a remote user dial authentication RADIUS request and an HTTP request sent by a remote terminal;
step S20, according to the received RADIUS request and HTTP request sent by the remote terminal, the CDN system provides a service corresponding to a preset rule for the remote terminal.
In this embodiment, a CDN server is deployed in a nodeB of a base station, and the CDN server may directly obtain a RADIUS (Remote Authentication dial in User Service) request and an HTTP (Hyper Text Transfer Protocol) request sent to the base station by a User, and set up a main server based on a plurality of CDNs of the base station to analyze and process the obtained request.
Referring to fig. 2, step S20 may include the following refinement steps:
and step S21, when a remote user dial authentication RADIUS request sent by a remote terminal is received, the RADIUS request is analyzed to obtain and associate the user identifier and the base station identifier.
When a user uses a mobile phone, a tablet computer and other terminals to surf the internet through mobile traffic, and when the user starts mobile traffic internet access service provided by an operator at the terminal, the terminal can send a remote user dialing authentication request to a base station to access a network, and the RADIUS request comprises a user identifier and a base station identifier, and the user identifier is associated with the base station identifier, wherein the user identifier can comprise a mobile phone number, an IP (Internet protocol) address of the user, or identification information of the user terminal, and the base station identifier can be information such as a base station ID (identity) or a specific position of the base station. When a RADIUS request sent by a remote terminal is received, the RADIUS request is analyzed, a user identifier and a base station identifier contained in the RADIUS request are obtained and associated, and for example, the obtained user identifier information such as a mobile phone number, an IP address of a user or identifier information of a user terminal is associated with a base station ID.
Step S22, when receiving the HTTP request sent by the remote terminal, obtaining access information and a user identifier corresponding to the HTTP request, and obtaining a base station identifier associated with the user identifier.
Step S23, updating the access statistical information corresponding to the obtained base station identifier according to the access information, where the access information includes an access address.
After the remote terminal successfully realizes the remote dialing authentication, a user accesses a website by sending an HTTP request, after receiving the HTTP request sent by the remote terminal, intercepts the HTTP request, obtains access information such as a URL (Uniform Resource Locator) of the HTTP request accessed by the user, domain information of the URL accessed by the user, access time, and the like, and a user identifier from the HTTP request, and obtains a base station identifier associated with the user identifier, because the URL accessed by each user may be repeated, for example, there is a case where a plurality of users access the same URL, after obtaining the access information, access statistical information corresponding to a base station identifier established in advance is updated, because the received HTTP request may be for different base stations, it is necessary to perform statistics on the access request of each base station, including, the number of times that the URL is accessed, the access time, and the like are updated, so that each time an HTTP request is received, the information such as the number of times that the URL corresponding to the HTTP request is accessed, the access time, and the like is updated, and the access heat of a certain URL address, for example, the number of times that a certain URL address is accessed within a certain period of time, can be obtained according to the information.
Step S24, when the access statistics information matches a preset rule, the CDN system provides a service corresponding to the preset rule for the remote terminal.
Preset rules may be preset, for example, a VIP mobile phone number is set, or when the number of access times of a certain URL reaches a certain number of times, or the access user is directed to a certain specific base station, and a corresponding directional service, such as directional acceleration, directional push, and the like, is configured for the preset rules. And when the updated access statistical information conforms to the configured preset rule, providing services corresponding to the preset rule, such as cache acceleration, advertisement pushing, bandwidth control, redirection and the like, for the remote terminal sending the RADIUS request and the HTTP request.
The access statistical information represents access hotspots of users, for example, hot videos, hot websites and the like in a specific base station area are counted, then, the website resources of the TOP100 are accelerated in a targeted manner, and in combination with the website access and videos of the TOP100, through big data calculation, corresponding recommendation information can be pushed for internet access of a specific user of a certain base station, for example, the base station in a commercial street is collected through a CDN, a link of a business that is taking a sales promotion activity near the base station, for example, the base station in a school dormitory, and relevant advertisement information can be pushed by collecting videos watched by student hotspots in the latest period of time. The user experience can be optimized, the behavior characteristics of the user can be fully mastered, and the refined flow management in the true sense is realized.
The service method of the mobile base station CDN system provided by this embodiment includes setting a CDN server at a base station, setting a preset rule in advance, analyzing a request to obtain a user identifier and a base station identifier and associating the user identifier and the base station identifier when receiving an RADIUS request sent by a remote terminal, obtaining access information and a user identifier corresponding to an HTTP request when the remote terminal sends the HTTP request to access a network, obtaining a base station identifier associated with the user identifier, updating access statistical information corresponding to the base station identifier, determining whether the access statistical information matches the preset rule, and if the access statistical information matches the preset rule, providing a service corresponding to the preset rule, such as cache acceleration, directional push, and the like, for the remote terminal, thereby solving a technical problem that an existing CDN cannot provide a directional service according to user access information of a specific base station.
Referring to fig. 3, a first embodiment of a service method based on the CDN system of the present invention provides a second embodiment of the service method of the CDN system of the mobile base station. In the present 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, acquiring the content corresponding to the HTTP request from the cache region.
Step S242, when the content corresponding to the HTTP request is acquired from the cache region, responding to the HTTP request and sending the content corresponding to the HTTP request in the cache region to the remote terminal corresponding to the user identifier.
When the service corresponding to the preset rule configured in advance provides cache acceleration for the remote terminal which sends the RADIUS request and the HTTP request and meets the preset rule, the content corresponding to the HTTP request is obtained from the cache region and is sent to the remote terminal.
Further, after step S241, step S24 further includes:
when the content corresponding to the HTTP request is not obtained from the cache region, downloading the content corresponding to the HTTP request from the source server corresponding to the HTTP request and responding to the remote terminal; and storing the content corresponding to the HTTP request to the cache region.
It can be understood that, when a certain URL address is accessed for the first time, even if the current access meets the requirement, the content corresponding to the HTTP request is not cached in the cache region, at this time, the content corresponding to the HTTP request is acquired from the source server corresponding to the HTTP request and responds to the remote terminal that sent the HTTP request, and the acquired content is stored in the cache region, and when a request meeting the preset rule is received again, a cache acceleration service is provided for the corresponding remote terminal.
Further, if the user identification and the access statistical information do not accord with the preset rules, the HTTP request is directly and transparently proxied to the destination address without any processing to the request.
For example, a user accessing the internet near a certain base station provides a cache acceleration service to the user, and it is assumed that the configured preset rule is that the number of access times of the URL of the video a of the favorite web site reaches 100 times, and the corresponding service is cache acceleration. When a user accesses the internet through a base station, firstly, an RADIUS request sent by a terminal of the user is analyzed, the request is analyzed to obtain a user identifier and a base station identifier, the user accesses a video A of a favorite web site, access information such as a Uniform Resource Locator (URL) address of the video A is obtained, the access times of the URL address are updated, if the access times reach 100 times, content corresponding to the HTTP request is cached, wherein statistics of the access times can be the access requests sent by different users, when the same HTTP request is received subsequently, caching acceleration service is provided for a remote terminal corresponding to the HTTP request, the content corresponding to the request in the cache can be directly sent to the remote terminal, the corresponding content does not need to be requested to an origin server, for the remote terminal, the response time of the HTTP request is accelerated, better internet access experience is brought for the user, and meanwhile, flow value increase is realized. The above is only a simple example, and in practical application, diversified preset rules can be created according to the requirements of different operators, so as to achieve more refined service experience.
In other embodiments, other directed services are possible, such as directed push, etc. And when the access statistical information accords with a preset rule which is configured and the service corresponding to the preset rule is advertisement push, pushing the configured advertisement information to a remote terminal which sends the HTTP request which accords with the preset rule.
Further, the method comprises the following steps:
and updating the preset rule according to the updated access statistical information.
Updating the preset rule according to the access statistical information, for example, when the popular website is changed, the preset rule can be updated according to the changed information; or the operator may set preset rules according to its own needs, for example, to provide a directed service for a specific VIP user, or to provide a directed service for a user at a specific location, or to provide a directed service for a user accessing a URL.
The invention also provides a CDN system of the mobile base station.
Fig. 4 is a functional module diagram of a CDN system of a mobile base station according to a first embodiment of the present invention.

When the obtained user identifier and the updated access statistical information conform to the configured preset rule, the execution unit 24 provides a service corresponding to the preset rule, such as cache acceleration, advertisement push, bandwidth control, redirection, and the like, for the remote terminal that issues the RADIUS request and the HTTP request.
The access statistical information represents access hotspots of users, for example, hot videos, hot websites and the like in a specific base station area are counted, then, a website resource of the TOP100 is accelerated in a targeted manner, in combination with the website access and videos of the TOP100, through big data calculation, corresponding recommendation information is pushed for internet access of a specific user of a certain base station, for example, the base station in a mall is collected through a CDN, the execution unit 24 can push links of merchants taking a promotion activity near the base station, for example, the base station in a school dormitory, and the execution unit 24 can push related advertisement information by collecting videos watched by the student hotspots in the latest period of time. The user experience can be optimized, the behavior characteristics of the user can be fully mastered, and the refined flow management in the true sense is realized.
The CDN system for the mobile base station provided by this embodiment is configured to set a CDN server at a base station, preset rules, parse, when receiving an RADIUS request sent by a remote terminal, to obtain and associate a user identifier and a base station identifier, when the remote terminal sends an HTTP request to access a network, obtain access information and a user identifier corresponding to the HTTP request, obtain a base station identifier associated with the user identifier, update access statistics information corresponding to the base station identifier, determine whether the access statistics information matches the preset rules, and if so, provide services corresponding to the preset rules, such as cache acceleration, directional push, and the like, for the remote terminal, thereby solving a technical problem that an existing CDN cannot provide a directional service according to user access information of a specific base station.
