The core of the CDN is to push the content and service in the center to the edge of the network by using an intelligent policy technology, so that a user can obtain the service in the nearest place and where the quality of service is the best, and key technologies of the CDN include caching, load balancing, content routing, content distribution, content storage, content management, and the like. Technical advantages of CDNs include: (1) the global load is balanced, the access speed is high, and the user can be connected to the nearest server. (2) And the hot content is actively transmitted, automatically tracked and automatically updated. (3) Seamless integration, high reliability, availability, and scalability. (4) The occupation of network bandwidth resources is reduced, and the intelligent management and control capability is achieved. (5) The transmitted content is protected and the content provider can decide locally on its own the content to serve. Based on the advantages, the CDN technology can improve the utilization rate of broadband resources, increase the application popularization of streaming media on the Internet, and greatly promote the development of Internet application and service, wherein the applications comprise online playing, music on demand, live television broadcast, interactive games and the like. CDN nodes are primarily based on cache servers, also called proxy caches, which are located near the internet edge of the mobile network.

A Gateway (GW) is a user plane functional entity, is used for user plane Data routing processing, and is divided into an S-GW (Serving Gateway) and a P-GW (Packet Data Network Gateway).
The S-GW is a mobile anchor point between Evolved Universal Radio access networks (E-UTRAN); the P-GW is a border gateway of a PDN (Packet Data Network, mobile Network and Packet Data Network), and is responsible for functions such as access to the PDN and forwarding of Data between the mobile Network and the PDN.
The RGW (Remote Gateway) is located between the eNB and the SGW, and is mainly used for identifying a data packet to be distributed and distributing the data packet to a CDN node connected to the data packet.
GSLB (Global Server Load Balance), which mainly implements traffic allocation between servers in different areas on a wide area network (including the internet), ensures that the user closest to the user is served by the best Server, and thus ensures the internet access quality.
A UE (User Equipment) is a User terminal in 3G and 4G networks, and is an MS (Mobile Station) in 2G networks, and the User Equipment may include a Mobile phone, an intelligent terminal, a multimedia device, or a streaming media device.
Referring to fig. 1, a flowchart of a first embodiment of a service offloading method based on a content distribution network according to the present application is shown, where the embodiment may be applied to a policy and charging rule function server, and the embodiment may include the following steps:
step 101: and responding to a first service shunting request, and acquiring an internet protocol address of a user carried by the first service shunting request.
In this embodiment of the present application, it is assumed that a user inputs a website to be accessed on a UE that the user holds, and after an access request of the website is triggered, a browser first accesses a master server corresponding to the website, and the master server sends a service response to the UE, where the service response includes master content. It will be appreciated that the return from the primary station server may be a message only informing that the UE has successfully connected to the primary station server, which may be only a few bytes in size. After receiving an access request of a user, the master station server acquires an IP address of the UE held by the user, carries the IP address in a first service offloading request, and sends the first service offloading request to the PCRF, so as to subsequently implement service offloading for the user, that is, offloading internet content that should be provided to the user by the master station server to a CND node, and providing the internet content to the user by the CDN node.
Referring to fig. 2, a scene architecture diagram of an actual application of the embodiment of the present invention is shown, where after receiving an access request sent by a user, a master station server 201 may send to a PCRF202 an IP address of the user carried in a first traffic offload request.
It can be understood that, if a certain user does not need to perform traffic offload, the master station server may directly return the internet content corresponding to the access request of the user to the user, and does not need to send a traffic offload request to the PCRF for the user that does not need to perform traffic offload. Because the master station server receives the service requests of a large number of users, the master station server can set a certain rule to determine which users need to perform service distribution and which users do not need to perform service distribution.
For example, if the master station server is an elutriation net server, the elutriation net server may determine which users need to be distributed according to the registration time of the users in the master station server or the transaction fee. For another example, if the transaction cost of the user a in one month exceeds ten thousand yuan, in this case, assuming that the user a sends a service request to the master station server, the IP address of the user a may be carried in the first service offloading request and sent to the PCRF, so as to implement subsequent service offloading for the user a. If the transaction cost of the user B in one month does not exceed ten thousand yuan, the step 101 does not need to be executed for the user B, and then the service distribution is not performed for the user B subsequently.
Of course, it is understood that those skilled in the art can set other traffic splitting rules at the primary station server, and the above description is only an example, and should not be construed as limiting the present application.
Step 102: and determining the packet data network gateway of the user according to the internet protocol address of the user.
After receiving a first service offloading request carrying an IP address of a user, the PCRF may obtain the IP address of the user from the first service offloading request, and further determine a PGW corresponding to the IP address of the current user according to a correspondence between the IP address of the user stored in the PCRF and a PGW203 (refer to fig. 2) to which the user belongs.
Step 103: and sending the internet protocol address of the user to the packet data network gateway.
In this step, the PCRF may send the IP address of the user to the PGW determined in step 102, and specifically, may carry the IP address of the user in the second service offloading request, so that the PGW determines the identity information of the user according to the internet protocol address of the user, and sends the identity information of the user to the remote gateway, so that the remote gateway locally implements service offloading for the user. The PGW may determine, according to an IP address of the user, identity information of the user, for example, account information registered by the user at the master server or information that can uniquely identify the user identity, such as a mobile phone number of the user, and forward a third service offloading request including the identity information of the user to the RGW204 (refer to fig. 2) through the SGW, where the RGW may implement service offloading for the user locally, so as to implement that the first CDN node 205 connected to the RGW directly provides internet content for the user.
Further, after step 103, the method may further include:
step 104: and receiving the service distribution response forwarded by the packet data network gateway.
After the RGW successfully implements service offloading for the user locally, the SGW may also send a service offloading response to the PGW to notify the PGW that the service offloading has been successfully implemented for the user, and the PGW then sends the service offloading response to the PCRF, so as to notify the PCRF that the user has successfully implemented service offloading.
As can be seen, in this embodiment, for the users needing offloading, the master station server sends the IP addresses of the users to the PCRF, and the PCRF further sends the IP addresses to the PGW, and the PGW may query to obtain the identity information of the users, and then sends the identity information to the RGW, so that offloading of the users is achieved by the RGW. Therefore, the effect of user-level distribution that different users can carry out distribution or not can be achieved, and the user carrying out service distribution can directly provide internet content for the user through the CDN node, so that the process that the user accesses the internet content is faster, the efficiency is higher, and the access experience of the user is improved.
Referring to fig. 3, a flowchart of a second embodiment of a service offloading method based on a content distribution network according to the present application is shown, where the present embodiment may be applied to a PGW, and the present embodiment may include the following steps:
step 301: and responding to the sent second service shunting request, and acquiring the internet protocol address of the user carried in the second service shunting request.
In this step, the PGW receives a second service offloading request which is sent by the PCRF and carries the IP address of the user, and may acquire the IP address of the user from the second service offloading request. It should be noted that the difference between the present embodiment and the first method embodiment is that the execution subject of the present embodiment is PGW, and other similarities may be referred to each other.
Step 302: and determining the identity information of the user according to the internet protocol address of the user.
The PGW determines identity information of the user according to the IP address of the user. The PGW may store a correspondence between an IP address of the user and the identity information, for example, the identity information corresponding to the user IP address "202.203.21" is a mobile phone number: 13855555555.
wherein, the step specifically comprises the steps of A1-A2:
step A1: and acquiring the corresponding relation between the internet protocol address and the identity information of the user.
Firstly, the PGW locally obtains a correspondence between an IP address of a user and identity information, where the identity information may be account information when the user registers in the master station server, and may uniquely identify one user, and may also enable a mobile phone number of the user to uniquely identify one user. In practical application, the identity information only needs to uniquely identify one user.
Step A2: determining identity information corresponding to the internet protocol address of the user according to the corresponding relation, wherein the identity information comprises: mobile phone number or/and account information.
And secondly, determining the identity information corresponding to the IP address according to the corresponding relation in the step A1.
Step 303: and sending a third service distribution request comprising the identity information of the user to a remote gateway.
Then, after determining the identity information of the user, the PGW may send the identity information of the user to the RGW, and the RGW implements traffic offload for the user locally. Specifically, the identity information of the user may be carried in the third service offloading request and sent to the RGW through the SGW. After the RGW performs traffic offload locally for the user, the access request sent by the user later may be forwarded to a CDN node (a first CDN node in fig. 2) connected to the RGW, and the CDN node connected to the RGW directly provides internet content to the user. It is understood that, in this embodiment, the SGW and the RGW may both store the identity information of the user.
Optionally, after step 303, the method may further include:
step 304: and receiving a service distribution response sent by the remote gateway.
After the RGW locally implements service offloading for the user, the RGW may also forward a service offloading response to the PGW through the SGW, so as to notify the SGW and the PGW that the user has implemented service offloading.
In this embodiment, for the users needing offloading, the master server sends the IP addresses of the users to the PCRF, and the PCRF further sends the IP addresses to the PGW, and the PGW may query to obtain the identity information of the users, and then sends the identity information to the RGW, so that the RGW implements offloading of the users. Therefore, the effect of user-level distribution that different users can carry out distribution or not can be achieved, and the user carrying out service distribution can directly provide internet content for the user through the CDN node, so that the process that the user accesses the internet content is faster, the efficiency is higher, and the access experience of the user is improved.
Referring to fig. 4, a flowchart of a third embodiment of a service offloading method based on a content distribution network according to the present application is shown, where the present embodiment may be applied to an RGW, and the present embodiment may include the following steps:
step 401: and responding to a third service distribution request, and acquiring the identity information of the user carried in the third service distribution request.
The difference between this embodiment and the first two embodiments is that the execution body is RGW, and similar points can be referred to by the same reference.
In this embodiment, for the RGW, if a third service offloading request forwarded by the PGW through the SGW is received, the identity information of the user is obtained from the third service offloading request.
Step 402: and locally realizing service distribution for the user according to the identity information of the user.
For the RGW, the received identity information of the user means that traffic splitting needs to be performed for the user. The RGW shunts the user corresponding to the received identity information to the CDN node connected to itself, so that the CDN node provides the internet content that the user needs to access to for the user. For example, if a user triggers an access request for internet content on the UE, for example, inputs a web address or triggers an operation of viewing internet content, the UE will first send the access request to the master server, and the master server will return a message of several bytes to inform that the UE has connected to the master server, and then, when the UE parses the message returned by the master server to request for resources of specific content of the master, such as pictures, etc., the request will be forwarded by the RGW to a service offload corresponding CDN node, so that the CDN node provides the specific internet content to the user.
Then, specifically, the implementation of this step may include steps B1 to B2:
step B1: and acquiring a target content distribution network node connected with the remote gateway.
First, the RGW acquires a target address, such as an IP address, of a CDN node connected to the RGW when it needs to perform traffic offload for a user corresponding to the received identity information.
Step B2: setting the target content distribution network node as a content provider of the user.
The RGW may then set the CDN node connected to itself in step B1 as the content provider for that user.
Optionally, after step 402, step 403 may be further included:
step 403: and responding to the service request sent by the user, and forwarding the service request to the target content distribution network node.
Under the condition that the user continues to send the service request, the RGW directly forwards the service request to the target CDN node determined in step 402, and the CDN node may send the content corresponding to the service request to the user. For example, for the picture resource mentioned in step 402, which the user needs to access further, the picture resource is directly queried locally by the CDN node and then sent to the user through the RGW.
Optionally, after step 402, step 404 may be further included:
step 404: and sending a service distribution response to the packet data network gateway, wherein the service distribution response is used for informing the packet data network gateway that the user has distributed to the target content distribution network node.
After the RGW implements service offloading for the user, a service offloading response may also be forwarded to the PGW through the SGW, so as to notify the PGW that the user has already been offloaded to the CDN node.
In this embodiment, for the users needing offloading, the master server sends the IP addresses of the users to the PCRF, and the PCRF further sends the IP addresses to the PGW, and the PGW may query to obtain the identity information of the users, and then sends the identity information to the RGW, so that the RGW implements offloading of the users. Therefore, the effect of user-level distribution that distribution or non-distribution can be carried out for different users is achieved, and the user carrying out service distribution can directly provide internet content for the user by the CDN node, so that the process of accessing the internet content by the user is faster, the efficiency is higher, and the access experience of the user is improved.

Wherein, the server may further include:
a first receiving module 504, configured to receive a service offloading response forwarded by the packet data network gateway.

Therefore, the effect of user-level distribution that distribution or non-distribution can be carried out for different users is achieved, and the user carrying out service distribution can directly provide internet content for the user by the CDN node, so that the process of accessing the internet content by the user is faster, the efficiency is higher, and the access experience of the user is improved.
