Based on the description of the traffic acceleration system, please refer to fig. 2, which is a flowchart illustrating a traffic acceleration method according to an exemplary embodiment of the present application, where the method can be applied to the traffic management unit, and specifically can be executed by hardware or/and software installed in the traffic management unit. The method comprises at least the following steps.
S210, receiving a flow acceleration request.
The traffic acceleration request is obtained by redirecting the packet data processing gateway when receiving the traffic acceleration request sent by the terminal. For example, a user sends a traffic acceleration request representing a forward traffic acceleration application through a service APP or the like installed on the terminal, and when receiving the traffic acceleration request, the packet data management unit forwards a packet whose destination address is an IP address of an acceleration request server (that is, the aforementioned traffic acceleration request) to the traffic control unit based on a preconfigured HyperText Transfer Protocol (HTTP) redirection rule.
Optionally, the message body in the traffic acceleration request may include a private network IP address (i.e., a source IP address) allocated to the terminal by the mobile network, a SERVICE type (SERVICE _ ID) of the target SERVICE applying acceleration, a current traffic state (STATUS) of the target SERVICE, a target acceleration duration (TIME) applying acceleration, a target LOCATION (LOCATION, such as a geographical area, etc.) applying acceleration, a public network IP address of the acceleration request server, and the like. Wherein the target location may be, but is not limited to, a location where the terminal is located, and the like.
S220, sending a secondary acceleration request to the packet data processing gateway.
And the secondary acceleration request is used for indicating the packet data processing gateway to inquire and feed back a user identifier corresponding to a source IP address included in the flow acceleration request. It is to be understood that one or more subscriber 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.
In this embodiment, the traffic management unit can obtain a complete traffic acceleration request of a user through a "secondary request for acceleration service" process. For example, the first request is a traffic acceleration request forwarded from the packet data processing gateway, where the traffic acceleration request carries a source IP address, a service type of a target service applying acceleration, a service state of the target service, a target acceleration duration of the target service applying acceleration, and the like. And the second request is from a second acceleration request sent by the traffic management unit to the packet processing gateway so as to request the packet processing gateway to inquire the MSISDN of the user.
And S230, performing compliance verification on the traffic acceleration request based on a preset acceleration white list under the condition that the user identifier is received, and inquiring a current traffic state corresponding to the user identifier based on a preset acceleration state library.
The acceleration white list is used for storing a user identifier (such as a user MSISDN) of a service acceleration service subscribed by a user, an accelerated service type subscribed by the user, an accelerated geographic area subscribed by the user, a target acceleration duration of a service subscribed by the user, and the like. In one implementation, the acceleration white list may be created autonomously by the traffic management unit, or may be obtained from a charging system.
In this embodiment, when performing 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 triple group of the current service acceleration state of the user, and the triple group can comprise a user identification, an acceleration service type ordered by the user and a service acceleration state ordered by the user. The traffic acceleration state may include three states, namely stop acceleration, start acceleration and pause acceleration.
For example, referring to fig. 3, when the user subscribes to the forward service acceleration service, the charging system inserts the specific content subscribed by the user into the acceleration control unit, and the acceleration state is the stop acceleration state; when a user applies for starting service acceleration, the acceleration state is a starting acceleration state; when the pause/stop is initiated, the acceleration state is a pause acceleration/stop acceleration. When the user cancels the subscription to the 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, under the condition that the check result passes and the current flow state is 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, when the check result passes and the current traffic state is the non-acceleration state, the acceleration control unit may send an acceleration request to the charging control unit, so that the charging control unit generates a target acceleration policy and issues the target acceleration policy in the network. For example, a new network bearer is created based on a media stream formed by a < source IP address, a destination IP address > in the network, and a higher-level QoS is allocated, in this case, when the terminal initiates a mobile internet access service, a target acceleration policy may be triggered to take effect, and a traffic is transmitted through the network bearer of the higher-level QoS, so that an acceleration effect is achieved.
In one implementation manner, when the verification result fails or/and the current traffic state is the acceleration state, the traffic management unit may feed back acceleration failure information or refuse to reply the traffic acceleration request to the terminal.
The traffic acceleration method provided by the embodiment is implemented by a mobile internet forward traffic acceleration system based on an intelligent pipeline and DPI fusion framework. The traffic management unit can perform real-time verification on the compliance of the traffic acceleration request under the condition of receiving the traffic acceleration request, construct a target acceleration strategy when the verification is passed, and issue the target acceleration strategy to the terminal, so that the terminal can perform real-time traffic acceleration when target service access is performed, thereby effectively utilizing the service type identification capability of a signaling system on one hand and solving the problem that a large number of service identification rules need to be statically configured for forward acceleration in the industry at present; on the other hand, the problem that the backward acceleration application range is limited in the industry is solved, the service acceleration function applicability is improved, the network entity overhead is reduced, the service acceleration real-time performance is improved, the 'autonomous acceleration' requirement of a user is met, and the timeliness and the accuracy of flow acceleration are ensured.
As shown in fig. 4, a flow chart of a traffic acceleration method according to another exemplary embodiment of the present application is schematically shown, and the method may be applied to the aforementioned traffic management unit, and may be specifically executed by hardware or/and software installed in the traffic management unit. The method comprises at least the following steps.
And S410, receiving the service subscription relation message.
The service subscription relationship message is obtained by forwarding the charging system after receiving the user application data sent by the terminal, and the service subscription relationship message may be a service subscription relationship message when the user subscribes to the flow acceleration service of the target service, or a service subscription relationship 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 user identification (e.g. user MSISDN), target service type of subscribed/cancelled target service, target acceleration position of subscribed/cancelled target service, target acceleration duration of subscribed/cancelled target service, and the like.
Illustratively, a user can order/cancel the flow acceleration service through a business hall (offline mode) or a service APP (online mode) installed on a terminal, correspondingly, a service manager or the user directly inputs the user application data into a customer management system through the service APP, and then the user application data is forwarded to the charging system through the terminal of the customer management system and the like, and the charging system generates a service order relation message based on the user application data and sends the service order relation message to the flow management unit.
And 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 relationship 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 relationship 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 further send a cancel/subscribe subscriber message to a charging control unit, and a cancel/subscribe subscriber identifier is used for the charging control unit to perform charging. Correspondingly, in order to ensure the information synchronization between the charging system and the charging control unit, when the charging unit completes the cancellation/subscription of the subscriber message, the confirmation information of whether the cancellation/subscription of the subscriber message is normally completed can be fed back to the charging system.
S430, sending information operation confirmation information to the charging system.
Illustratively, the acceleration control unit completes the insertion (or deletion) of the subscription relationship in the acceleration white list, completes the setting of the user state (i.e. the current traffic state) in the user state library, and replies operation confirmation information for representing whether the insertion of the subscription relationship is normally completed (cancelled) to the charging system.
S440, receiving a flow acceleration request.
S450, sending a secondary acceleration request to the packet data processing gateway.
For specific implementation processes in S440 and S450, reference may be made to the foregoing detailed description in S210 and S220, which is not described herein again.
And S460, performing compliance verification on the traffic acceleration request based on a preset acceleration white list under the condition that the user identifier is received, and inquiring the current traffic state of the user identifier based on a preset acceleration state library.
In addition to the detailed implementation process in S230, in an implementation manner, the step of performing compliance check on the traffic acceleration request based on the preset acceleration white list in S460 may include at least one of the following steps.
(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 not stored, the verification result is passed.
(2) And checking whether the target acceleration duration included in the traffic acceleration request is not greater than the acceleration duration in the acceleration white list. For example, if not, the check result passes, otherwise, the check result fails.
(3) And checking whether the acceleration state change relation corresponding to the target service conforms to the acceleration state conversion logic. For example, if the result is matched, the verification result is passed, otherwise, the verification result is not passed, and the abnormal state transition condition such as direct order cancellation from the starting acceleration state can be avoided through the setting of the verification process.
(4) And checking whether the acceleration times of the target service in a preset time length exceed a preset value. For example, if not, the check result passes, otherwise, the check result fails. Through the setting of the verification process, malicious or abnormal acceleration conditions can be avoided.
