It should be noted that the aforementioned flow acceleration system may have more or fewer devices, units than in fig. 1. In addition, the flow management unit may be a stand-alone device, or may be integrated with one or more of the foregoing devices, which is not limited in this implementation.
Based on the foregoing description of the flow acceleration system, please refer to fig. 2 in combination, which is a schematic flow chart of a flow acceleration method according to an exemplary embodiment of the present application, the method may be applied to the foregoing flow management unit, and may be specifically executed by hardware or/and software installed in the flow management unit. The method at least comprises the following steps.
S210, receiving a flow acceleration request.
The flow acceleration request is redirected by the packet data processing gateway when the flow acceleration request sent by the terminal is received. For example, the user sends a traffic acceleration request representing a forward traffic acceleration application through a service APP installed on the terminal, and when receiving the traffic acceleration request, the packet data management unit forwards a data packet (i.e. the foregoing traffic acceleration request) with a destination address being the IP address of the acceleration request server to the traffic control unit based on a pre-configured hypertext transfer protocol (HyperText Transfer Protocol, HTTP) redirection rule.
Optionally, the message body in the traffic acceleration request may include a private network IP address (i.e., source IP address) allocated to the terminal by the mobile network, a SERVICE type (service_id) of a target SERVICE to which acceleration is applied, a current traffic state (STATUS) of the target SERVICE, a target acceleration duration (TIME) to which acceleration is applied, a target LOCATION (LOCATION, such as a geographic area, etc.) to which acceleration is applied, and a public network IP address of the acceleration request server. Wherein the target location may be, but is not limited to, a location where the terminal is located, etc.
S220, sending a secondary acceleration request to the packet data processing gateway.
The secondary acceleration request is used for indicating the packet data processing gateway to inquire a user identifier corresponding to a source IP address included in the flow acceleration request and feed back the user identifier. It will be appreciated that one or more user identities corresponding to the source IP address are pre-stored in the packet data processing gateway. In this embodiment, the user identifier may be, but is not limited to, a user MSISDN or the like.
In this embodiment, the flow management unit may obtain the complete flow acceleration request of the user through the process of "acceleration service secondary request". For example, the first request is a traffic acceleration request forwarded by the packet data processing gateway, where the traffic acceleration request carries a source IP address, a service type of a target service for acceleration, a service state of the target service, and a target acceleration duration of the target service for acceleration. And a second request, namely a second acceleration request sent by the flow management unit to the packet processing gateway, so as to request the packet processing gateway to inquire about the MSISDN of the user.
And S230, under the condition that the user identifier is received, carrying out compliance verification on the flow acceleration request based on a preset acceleration white list, and inquiring the current flow state corresponding to the user identifier based on a preset acceleration state library.
The acceleration white list is used for storing user identification (such as user MSISDN) of the acceleration service subscribed to by the user, acceleration service type subscribed to by the user, acceleration geographic area subscribed to by the user, target acceleration duration of the service subscribed to by the user, and the like. In one implementation, the acceleration whitelist may be created autonomously by the traffic management unit or may be obtained from a billing system.
In this embodiment, when the traffic management unit performs compliance verification based on the acceleration white list, the traffic management unit may perform verification based on one or more items of content stored in the acceleration white list, which is not limited in this embodiment.
The acceleration state library is used for storing a current service acceleration state triplet of the user, and the triplet can comprise a user identifier, an acceleration service type subscribed by the user and a service acceleration state subscribed by the user. The service acceleration state may include three types of stopping acceleration, starting acceleration and suspending acceleration.
For example, referring to fig. 3 in combination, when a user subscribes to a forward-looking business acceleration service, the billing system inserts user subscription details into the acceleration control unit, and the acceleration state is a stop acceleration state; when a user applies for starting service acceleration, the acceleration state is a starting acceleration state; when the pause/stop is started, the acceleration state is pause acceleration/stop acceleration. When the user cancels the subscription acceleration service, the billing system deletes the subscription content to the acceleration control unit. Correspondingly, the current flow state comprises a stop acceleration state, a start acceleration state or a pause acceleration state.
And S240, when the verification result passes and the current flow state is in a non-acceleration state, constructing a target acceleration strategy based on the flow acceleration request and sending the target acceleration strategy to the terminal, so that the terminal performs flow acceleration based on the target acceleration strategy when accessing a target service corresponding to the flow acceleration request.
In one implementation manner, the acceleration control unit may send an acceleration request to the charging control unit when the verification result passes and the current traffic state is a non-acceleration state, so that the charging control unit generates a target acceleration policy and issues the target acceleration policy in the network. For example, based on the media stream composed of the source IP address and the destination IP address in the network, a network bearer is newly established, and a higher level QoS is allocated, in this case, when the terminal initiates the mobile Internet access service, the terminal can trigger the target acceleration policy to take effect, and the traffic is transmitted through the network bearer of the high level QoS, so as to achieve the acceleration effect.
In one implementation manner, the flow management unit may feed back acceleration failure information or refuse to reply the flow acceleration request to the terminal when the verification result is not passed or/and the current flow state is an acceleration state.
The foregoing flow acceleration method provided in this embodiment is implemented by a mobile internet forward flow acceleration system based on a fusion architecture of an intelligent pipeline and a DPI. The traffic management unit can verify compliance of the traffic acceleration request in real time under the condition of receiving the traffic acceleration request, constructs a target acceleration strategy when verification passes, and issues the target acceleration strategy to the terminal so that the terminal can realize real-time traffic acceleration when performing target service access, thereby effectively utilizing service type identification capability of the signaling system and solving the problem that forward acceleration in the industry currently requires static configuration of a large number of service identification rules; on the other hand, the method and the device also solve the problem of limited backward acceleration application range in the industry, improve the applicability of the service acceleration function, reduce the cost of network entities, improve the real-time performance of service acceleration, realize the 'autonomous acceleration' requirement of users and ensure the timeliness and the accuracy of flow acceleration.
As shown in fig. 4, a flow chart of a flow acceleration method according to another exemplary embodiment of the present application may be applied to the foregoing flow management unit, and may be specifically executed by hardware or/and software installed in the flow management unit. The method at least comprises the following steps.
S410, receiving service subscription relation information.
The service subscription relation message is forwarded by the charging system after receiving the user application data sent by the terminal, and the service subscription relation message may be a service subscription relation message when the user subscribes to the flow acceleration service of the target service, or a service subscription relation message when the user cancels the flow acceleration service of the target service, which is not limited in this embodiment.
The user application data includes user information and target service information, such as a user identifier (e.g., a user MSISDN), a target service type of a subscribed/cancelled target service, a target acceleration position of the subscribed/cancelled target service, a target acceleration duration of the subscribed/cancelled target service, and the like.
The user can subscribe/cancel the traffic acceleration service through a business hall (off-line mode) or a service APP (on-line mode) installed on a terminal, and accordingly, a service manager or the user directly inputs user application data into a client management system through the service APP, forwards the user application data to the charging system through the terminal installed with the client management system, and then the charging system generates a service subscription relation message based on the user application data and sends the service subscription relation message to the traffic management unit.
S420, performing target operation on a preset acceleration white list and a user state library according to the service subscription relation message.
Wherein the target operation may include at least one of an information insertion operation, an information modification operation, and an information deletion operation.
For example, the charging system sends an insert/cancel subscription relation message to the traffic management unit, and the traffic management unit may insert/delete user information in the acceleration white list according to the service subscription relation message, and set the current traffic state to stop acceleration (insert scenario) or delete the current traffic state (delete scenario) in the user state library.
In one implementation, the charging system may also send a cancel/sign-up subscriber message to a charging control unit, with the cancel/sign-up subscriber identity being used for charging by the charging control unit. Accordingly, in order to ensure the synchronicity of the information between the charging system and the charging control unit, when the charging unit completes the cancellation/subscription subscriber message, the confirmation information of whether to normally complete the cancellation/subscription subscriber message may be fed back to the charging system.
S430, sending information operation confirmation information to the charging system.
Illustratively, the acceleration control unit completes inserting (or deleting) the subscription relationship in the acceleration white list, and completes setting the user state (i.e., the current traffic state) in the user state library, and replies operation confirmation information for indicating whether to normally complete (cancel) the subscription relationship insertion to the charging system.
S440, receiving a flow acceleration request.
S450, sending a secondary acceleration request to the packet data processing gateway.
The specific implementation process in S440 and S450 may refer to the detailed descriptions in S210 and S220, and will not be described herein.
S460, under the condition that the user identifier is received, carrying out compliance verification on the flow acceleration request based on a preset acceleration white list, and inquiring the current flow state of the user identifier based on a preset acceleration state library.
In addition to the detailed description of S230, in an implementation manner, the step of verifying compliance of the flow acceleration request based on the preset acceleration white list in S460 may include at least one of the following.
(1) And checking whether the user identification and the service type of the target service are stored in the acceleration white list. For example, if the user identifier and/or the service type of the target service are/is not stored, the verification result is not passed.
(2) And checking whether the target acceleration duration included in the flow acceleration request is not greater than the acceleration duration in the acceleration white list. For example, if not greater than, the verification result passes, otherwise, the verification result fails.
(3) And checking whether the acceleration state change relation corresponding to the target service accords with acceleration state conversion logic. For example, if the verification result is in conformity, the verification result is passed, otherwise, the verification result is not passed, and by setting the verification process, abnormal state transition situations such as direct cancellation of ordering from the start acceleration state can be avoided.
(4) And checking whether the acceleration times of the target service in the preset time exceeds a preset value. For example, if not exceeded, the verification result passes, otherwise, the verification result fails. Through the setting of the verification process, malicious or abnormal acceleration conditions can be avoided.
It should be noted that if the step of compliance verification includes at least two of the four foregoing, it may be determined that the compliance verification result passes when both pass, and conversely, the verification result does not pass.
And S470, when the verification result passes and the current flow state is in a non-acceleration state, constructing a target acceleration strategy based on the flow acceleration request and sending the target acceleration strategy to the terminal, so that the terminal performs flow acceleration based on the target acceleration strategy when accessing a target service corresponding to the flow acceleration request.
In addition to the detailed description of S240, in the specific implementation process of S470, in one implementation, the process of constructing the target acceleration policy based on the traffic acceleration request described in S470 includes: sending an IP query request to a signaling system, wherein the IP query request is used for indicating the signaling system to query a target IP address of the target service and feeding back the target IP address; under the condition that the target IP address is received, modifying the current flow state corresponding to the user identifier in the acceleration state library, and recording the target acceleration duration; constructing a target acceleration strategy, wherein the target acceleration strategy comprises at least one of the user identifier, the source IP address, the target IP address, a target acceleration state and a target acceleration duration.
For example, considering that parameters such as a source IP address, a destination IP address (i.e., an IP address of an internet server public network), a user MSISDN, a target acceleration duration, a target acceleration state and the like need to be provided for traffic acceleration of a target service, and the DPI deep packet inspection function of the signaling system can provide a function of inquiring a corresponding relationship between a service type and an IP address of the internet server in real time, so that in order to construct a complete target acceleration policy, the acceleration control unit can search in real time for a destination IP address corresponding to the service type of the target service for acceleration, such as a sequence < destination IP1, destination IP2, … …, destination IPn >, and generate a target acceleration policy based on the user MSISDN, the source IP address, the destination IP address, the target acceleration state, the target acceleration duration and the like, and send the target acceleration policy to the terminal.
In another implementation, after constructing the target acceleration policy, constructing the target acceleration policy based on the traffic acceleration request further includes: and sending the target acceleration policy to a charging control unit, so that the charging control unit accelerates the flow based on the target acceleration policy.
