The executive agent of above step is strategy and charging regulation function entity (Policy and Charging Rule Function, PCRF).
Optionally, the business stream information of terminal (User Equipment, UE) can be by flow monitoring functional entity (Traffic Detection Function, TDF) reports PCRF, can also be by content distribution functional entity (Content Delivery Function, CDF) report PCRF.
Specifically, TDF can intercept and capture the miscellaneous service request that terminal is sent to business tine source or CDF, the business please It can be HTTP (Hyper Text Transfer Protocol, HTTP) Get request, the service class of request to ask Type can be video playback request, web access request etc..TDF can be according to the unified money carried in the service request intercepted and captured Source finger URL (Uniform Resource Locator, URL) identifies the classification belonging to business, determines service identification and industry The information such as business stream five-tuple information, wherein, Business Stream five-tuple information includes：The source IP address and port numbers of CDF are pointed to, is pointed to The purpose IP address and port numbers of terminal, and transmission control protocol (the Transmission Control that business is used Protocol, TCP).
The request of intercepting and capturing terminal traffic and the further operation of the business stream information of acquisition terminal that above-mentioned TDF is performed, Can by improving after CDF perform, improvement to CDF can be, for example：Increase on existing CDF with Business Stream inspection The unit of brake, and the interface that increase is interacted with PCRF on CDF etc..
TDF or CDF by the Business Stream information reporting of terminal to PCRF after, PCRF can be according to business stream information, Yi Jizhi One of user signing contract information and network state of few terminal, search default business game, determine the first business transmission control plan Slightly with the first service optimization control strategy.Wherein, business game for PCRF pre-set for basis to different terminals, Under different network environments, the different business classification of request when carry out a kind of dynamic strategy of differentiation control, dynamic strategy tool Body includes being determined for traffic flow template, charging method, the business transmission service quality of the business transmission of terminal (Quality Of Service, QoS), gating information etc., and for determining the mandate most great cause of service optimization control strategy Business bandwidth, whether allow service optimization configured information etc..Wherein, traffic flow template is used for PCEF identification business data flows, so that Business data flow is associated with corresponding transmission carrying；Charging method is shown to be online charging or offline charging, Yi Jishi According to flow, duration or event charging；Business transmission service quality includes QoS class letters (QoS Class Identifier), maximum bit rate (Maximum Bit Rate, MBR), guarantee bit rate (Guaranteed Bit Rate, GBR), distribution with keep priority (Allocation and Retention Priority, ARP) etc. parameter, be used for PCEF sets up business transmission and carries；Gating information includes gating state, and gating state shows to allow to transmit current video number to open According to stream, otherwise forbid transmission；The maximum transmission bandwidth of a width of transmission services of maximum traffic band of mandate, for limiting CDF to industry The rate conversion that business is carried out；Service optimization is indicated for allowing or forbidding CDF that treatment is optimized to business.
By taking video traffic as an example, the upper default business games of PCRF can be embodied in the following aspects：
Differentiation control is provided according to source video sequence, for example：For the carrier network from internet (Internet) Third party content (Over The Top, OTT) video not operator controlled of upper transmission provides the transmission done one's best QoS, does not do optimization processing to video；To having third party content provider (the Business to of cooperative relationship by oneself Business, B2B) video or the video of operator (Business to Client, B2C) on one's own account high priority is provided Transmission QoS, and implement video optimized treatment, with adaptive terminal ability to play and transmission bandwidth；
Differentiation control is realized according to user video grade, for example：User to different stage distributes different transmission belts Wide and video optimized control, Gold Subscriber can distribute highest video transmission bandwidth, and provide video optimized service；Silver Board user can distribute medium video transmission bandwidth, and provide video optimized service；Bronze Subscriber can distribute relatively low Bandwidth, video optimized service is not provided；
Differentiation control is realized according to the video genre that user contracts, for example：Only the video to user's signing provides bandwidth Ensure and video optimized treatment, the video for non-signing only provides the service of doing one's best.
Based on the factor of above-mentioned setting business game, the business game of the video traffic of formation can include, for example：Depending on Frequency strategy 1, the video bearer of correspondence high priority, maximum 2M video bandwidths, it is allowed to which CDF optimizes treatment to video；Video Strategy 2, the video bearer of correspondence high priority, maximum 1M video bandwidths, it is allowed to which CDF optimizes treatment to video；Video plan Slightly 3, correspondence low priority (doing one's best) transmission is carried, maximum 500K video bandwidths, it is allowed to which CDF optimizes place to video Reason；Video strategy 4, correspondence low priority (doing one's best) transmission is carried, and maximum 500K video bandwidths do not allow CDF to video Optimize treatment etc..
Below only as a example by being business, the default business games of PCRF are illustrated, it is to be understood that PCRF can be with According to actual needs, or the actual Adjustment effect according to business Transmission Control Strategy and service optimization control strategy etc. set or Modification business game.
After PCRF receives the business stream information of terminal, can be according to the business of the terminal request carried in business stream information Mark and Business Stream five-tuple information, find the user signing contract information of terminal, wherein, user signing contract information can be signed from ownership About server (Home Subscriber Server, HSS)/attaching position register (Home Location Register, ) etc. HLR obtained in network element.PCRF can further according to user business stream information, user signing contract information and current net Network state, determines the first business Transmission Control Strategy and the first service optimization control strategy.
First business Transmission Control Strategy can be handed down to PCEF by PCRF, and strategy performs entity (Policy with charging And Charging Enforcement, Function, PCEF), the traffic assignments resource for terminal request is performed by PCEF Operation, can be specifically：Terminal to the carrying of PCEF is changed, to meet the qos requirement of the business of terminal request.
PCEF returns to response message after the operation for performing resource allocation to PCRF, if response message indicates resource point The operation success matched somebody with somebody, then the first service optimization control strategy can be handed down to CDF by PCRF by TDF, or can be by first Service optimization control strategy is directly handed down to the interface CDF for having between PCRF and interacting, and is performed to terminal transmission from CDF The operation that business is optimized.First service optimization control strategy may indicate whether to allow CDF to the business to terminal transmission The action type of optimization is optimized and allows, if it is allowed, then CDF can carry out lattice to the business datum for being sent to terminal The operations such as formula conversion, Compression conversion, so that the disposal ability or the maximum belt of mandate of the business datum of transmission and terminal Width matches；If it is not allowed, then CDF can be directly from local cache or from the affiliated content source of the business of terminal request Obtain corresponding service and be sent to terminal.
If the operation failure of response message instruction PCEF resource allocations, PCRF can issue mistake by TDF to CDF Indicate, or mistake can be indicated directly be handed down to have the CDF of the interface for interacting between PCRF, CDF is stopped to terminal Transmission services.
When the user signing contract information of terminal changes, or network state, when changing, PCRF can be according to change User signing contract information afterwards and/or network state, adjustment are handed down to the business Transmission Control Strategy of PCEF, so that PCEF is to terminal The resource allocation of requested service and terminal subscribed services in itself and network condition are adapted；Make the business for being handed down to CDF excellent The traffic handing capacity and network state for changing control strategy and terminal itself match.
Distribution of services control method provided in an embodiment of the present invention, PCRF according to the business information of the business of terminal request, User signing contract information and network state, it is dynamic to determine business Transmission Control Strategy and service optimization control strategy, and by business Transmission Control Strategy is handed down to PCEF, PCEF is carried out resource allocation to the business of terminal；Service optimization control strategy is issued To CDF, make CDF to being optimized to the business of terminal transmission.So as to the different business for realizing different user rationally takes network Resource, and optimization processing is implemented to business tine, it is to avoid cause network congestion, it is ensured that the regular traffic experience of user.
The schematic flow sheet of distribution of services control method another embodiment that Fig. 2 is provided for the present invention, as shown in Fig. 2 The method includes：
S201, the first service request according to the terminal for obtaining, obtain the business stream information of terminal, in business stream information extremely Include the service identification and Business Stream five-tuple information of terminal request less；
S202, by Business Stream information reporting to strategy with charging regulation function entity PCRF so that PCRF is according to Business Stream One of user signing contract information and network state of information and at least terminal, search corresponding business game, determine the first business Transmission Control Strategy and the first service optimization control strategy；
If the first service optimization control strategy that S203, reception PCRF are issued, according to the first service optimization control strategy, To being optimized to the business of terminal transmission.
The executive agent of above step can be TDF, can also be and increased the unit with business current detection functionality, and And increased the CDF of the interface interacted with PCRF.
When the executive agent of above-mentioned steps is TDF, TDF can intercept and capture terminal and be sent to business tine source or CDF Miscellaneous service is asked, can be according to URL (the Uniform Resource carried in the service request intercepted and captured Locator, URL) classification described in business is identified, determine service identification and Business Stream five-tuple information, including：Point to The source IP address and port numbers of CDF, point to the purpose IP address and port numbers of terminal, the TCP that business is used.
TDF can will carry the Business Stream information reporting of service identification and Business Stream five-tuple information to PCRF, work as PCRF When returning to the first business Transmission Control Strategy or error message to TDF, TDF can be direct by the first business Transmission Control Strategy CDF is sent to, or, the first business Transmission Control Strategy can also be carried and returned in the service request of terminal by TDF CDF。
Need explanation when, if PCRF is redefined according to user signing contract information and/or network state after change The service optimization control strategy for issuing, the then service optimization control strategy that TDF directly can re-issue PCRF is handed down to CDF；Or, TDF can also be after another service request of the terminal for same business be intercepted, the industry that PCRF is re-issued Business Transmission Control Strategy is carried and returns to CDF in the service request.
Optionally, after TDF receives the first service optimization control strategy for miscellaneous service request that PCRF is issued, can Do optimization processing will only allow the corresponding Optimal Control Strategy of service request for optimizing to be transmitted to CDF, without allow into The corresponding Optimal Control Strategy of service request of row optimization can not be transmitted to CDF, and be transmitted directly to business and provide source.
Optionally, TDF can with preset domain name or url list, after TDF intercepts and captures the service request that terminal sends, if The domain name or URL included in the service request are present in pre-configured list, then TDF directly can send out the service request Giving CDF carries out follow-up optimization processing；If the domain name included in service request or URL are not present in pre-configured list In, the service request is not sent to CDF and optimizes treatment by TDF, is transmitted directly to business and is provided source.Should during TDF with PCRF does not have interaction.
Optionally, TDF can also point to certain or certain port (for example：Port 80) all service requests it is all direct Being transmitted to CDF carries out subsequent treatment, is judged whether to optimize current business treatment by CDF.TDF and PCRF does not have during being somebody's turn to do There is interaction.
When the executive agent of above-mentioned steps is that increased the unit with business current detection functionality, and increased and PCRF During the CDF of interactive interface, can detect that the business that terminal sends please by the unit of increased business current detection functionality in CDF Ask, and then obtain service identification and business five-tuple information, and PCRF is reported by the increased interface interacted with PCRF. When the first business Transmission Control Strategy that the interface interacted with PCRF to PCRF is issued, if the transmission control of the first business Tactful CDF optimizes permission to the business for being transferred to terminal, then CDF can enter row format to the business datum for being sent to terminal The operations such as conversion, Compression conversion, so that the disposal ability or the maximum bandwidth of mandate of the business datum of transmission and terminal Match；If it is not allowed, then CDF can be obtained directly from local cache or from the affiliated content source of the business of terminal request Take corresponding service and be sent to terminal；If receiving the error message that PCRF is issued, CDF stops to terminal transmission business.
If PCRF has redefined the business for issuing excellent according to user signing contract information and/or network state after change Change control strategy, then after CDF receives the business Transmission Control Strategy that PCRF is re-issued, can be re-issued according to PCRF Service optimization control strategy optimizes treatment to the business sent to terminal.
Terminal traffic can be asked corresponding industry by distribution of services control method provided in an embodiment of the present invention, TDF or CDF Business stream information reports PCRF, and PCRF can be according to the business information of the business of terminal request, user signing contract information and network-like State, it is dynamic to determine service optimization control strategy, and be directly handed down to CDF, or CDF is handed down to by TDF, make CDF to The business of terminal transmission is optimized.So as to the different business for realizing different user rationally takes Internet resources, and in business Hold and implement optimization processing, it is to avoid cause network congestion, it is ensured that the regular traffic experience of user.
The schematic flow sheet of distribution of services control method another embodiment that Fig. 3 is provided for the present invention, as shown in figure 3, The method includes：
S301, the first business Transmission Control Strategy that strategy is issued with charging regulation function entity PCRF is received, first Business Transmission Control Strategy is believed by PCRF according to user's signing of the business stream information and at least terminal of the business of terminal request One of breath and network state, search corresponding business game, it is determined that；
S302, according to the first Transmission Control Strategy, the business to terminal request carries out resource allocation.
The executive agent of above step can be PCEF, and the PCEF can be the network element, or and TDF being separately provided And/or CDF integrates the network element of setting.
After PCEF receives the first business Transmission Control Strategy that PCRF is issued, according to the first business Transmission Control Strategy, If without available carrying between terminal and PCEF, PCEF can be directed to the newly-built carrying of business of terminal request；If terminal There is available carrying between PCEF, then PCEF can change the QoS and traffic flow template (Traffic Flow of current carrying Template, TFT) etc. information.
If resource allocation operations run succeeded, PCEF can indicate resource point by returning to the response message of PCRF With operating successfully, so that PCRF is to CDF issuing service Optimal Control Strategies；If resource allocation performs failure, PCEF can be with Indicate resource allocation to fail by response message, so that PCRF issues error message to CDF, indicate CDF to stop to terminal transmission Corresponding business.
Further, when the user signing contract information of terminal changes, or network state is when changing, and PCRF can be with Dynamic adjustment is handed down to the business Transmission Control Strategy of PCEF, the business transmission control that PCEF can be redefined according to PCRF Strategy, adjusts the resource allocation of terminal request business, so as to be adapted with terminal subscribed services in itself and network condition.
