Embodiment
In order to make those skilled in the art person understand technical scheme in the embodiment of the invention better, and the above-mentioned purpose of the embodiment of the invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing technical scheme in the embodiment of the invention is described in further detail.
A kind of method and apparatus that pushes band width service is provided in the embodiment of the invention, to improve real-time and the accuracy that band width service pushes, has improved the user and experience.
Referring to Fig. 1, be a kind of flow chart that pushes the method embodiment of band width service provided by the invention, this method specifically can may further comprise the steps:
Step 101, determine to meet the user profile of band width service pushing condition;
Among this embodiment, before carrying out the band width service propelling movement, at first need to determine to meet the user that band width service pushes, namely identify potential band width service and push object.
Usually, potential band width service pushes the frequent accessing video of object, game website, and certain consumption strength is arranged, and is bigger to bandwidth demand, and bandwidth is less in the present signatory band width service.This part obtain manner that meets the user's that band width service pushes information mainly contains following several:
(1) analyzes with the band width service supplying system to CRM(Customer relationship management, customer relation management) goes up the attribute of user information of gathering, for example: information such as the band width service set meal type of name, sex, age, occupation, user gradation, order, as the source data of analyzing bandwidth service propelling object;
(2) analysis is gathered user traffic data with the band width service supplying system to probe, for example gathers at Gn mouth, Gi mouth, with the source data of data on flows as analysis bandwidth service propelling object;
Usually, potential band width service pushes object owing to frequent accessing video, game website, all has bigger customer flow.
(3) analyze with the band width service supplying system to OCS(Online Charging System, Online Charging System) go up and gather charge information, with the source data of charge information as analysis bandwidth service propelling object.
Compare with general user, potential band width service pushes object owing to have bigger flow, has the higher station message recording usually.
Usually, the band width service of operator's issue generally is the form of set meal bag, for example:
The basis set meal bag A:30 unit/moon, bag 100M flow, maximum bandwidth 1M, access service is not limited;
The basis set meal bag B:50 unit/moon, bag 200M flow, maximum bandwidth 2M, access service is not limited;
Accelerate set meal bag C:3 unit, the term of validity 1 day, maximum bandwidth 2M, access service is not limited;
Accelerate set meal bag D:5 unit, the term of validity 1 day, maximum bandwidth 4M, access service is not limited.
Suppose that user A has ordered basic set meal bag A, user A contacts management system (User contact management by business hall or user, UCM) etc. electronic channel is finished set meal and is ordered, CAMEL-Subscription-Information by CRM or Service Activation System (provision) be synchronized to OCS and the strategy with the charging decision making function (Policy and Charging Rule Function, PCRF).
Step 102, according to the current ongoing business data flow of described user, monitor the actual bandwidth requirements of described business data flow;
In this step, when the user initiates Operational Visit, by the current ongoing concrete business data flow of real-time perception user, with the actual bandwidth demand of monitoring current business visit.
Step 103, when described actual bandwidth requirements is higher than the current signatory bandwidth value of described user, push corresponding band width service according to described actual bandwidth requirements to described user.
In this step, compare monitoring the actual bandwidth demand of the current business visit that obtains and user's signatory bandwidth, judge whether the current bandwidth service satisfies the current business demand, if the actual bandwidth demand that monitoring result shows is higher than the current signatory bandwidth of user, be reference with the actual bandwidth requirements that monitors then, push corresponding band width service service to the user, recommend suitable band width service to the user.
In the embodiment of the invention, when the user initiates Operational Visit, by the current ongoing business data flow of real-time perception user, to monitor the actual bandwidth requirements of described business data flow, when the actual bandwidth requirements is higher than the current signatory bandwidth value of user, push corresponding band width service service according to the actual bandwidth requirements to the user, thereby recommend suitable band width service to the user.Owing to push band width service real-time detection actual bandwidth requirements when user's access service, be that the basis is carried out band width service and pushed with this professional actual bandwidth requirements, make the real-time and the accuracy that push band width service improve greatly.
When specifically implementing technical solution of the present invention, the implementation of the actual bandwidth requirements of the described business data flow of monitoring in above-described embodiment described in the step 102 specifically can may further comprise the steps:
Presetting in the width monitoring sampling period, the number-of-packet of handling according to the number of dropped packets of described business data flow and success is calculated the actual bandwidth demand sampled value of described business data flow;
According to the statistics that presets a plurality of described actual bandwidth demand sampled values in the monitoring time, obtain the actual bandwidth requirements of described business data flow.
In this execution mode, (that is: preset the width monitoring sampling period by adding up a short time, for example: the 3 seconds) number-of-packet of the number of dropped packets of user service data stream and success processing, calculate and obtain the current actual bandwidth demand sampled value of business data flow in this sampling period of user, and (determined by the monitoring duration parameters presetting monitoring time, repeatedly carry out the sampling of actual bandwidth demand for example: 60 seconds), and then, according to the statistics that presets a plurality of actual bandwidth demand sampled values in the monitoring time, obtain the actual bandwidth requirements of described business data flow.
After the actual bandwidth requirements that obtains user's current business data flow, just can be according to the comparative result between actual bandwidth requirements and the current signatory bandwidth value of user, determine whether deficiency of current signatory bandwidth.If current signatory bandwidth deficiency then pushes the band width service that is higher than described signatory bandwidth value to this user.
In the practical application, user's signatory bandwidth is divided according to up, down direction usually, and wherein, upstream bandwidth is represented user's maximum uplink bandwidth, and downlink bandwidth is represented user's maximum downstream transmission bandwidth.Usually, upstream bandwidth monitoring threshold and downlink bandwidth monitoring threshold are set to contract accordingly bandwidth value.
Particularly, if width monitoring found that, in the duration of presetting the monitoring time definition, measure to obtain the peak bandwidth requirements be higher than the current signatory bandwidth value of user and (determined by last/downlink bandwidth monitoring threshold parameter, as: the downlink bandwidth monitoring threshold is 1M), then determine the current signatory bandwidth deficiency of user.
Perhaps, when judging that signatory bandwidth is whether enough, increasing a judgement ratio (determines by judging scale parameter, as: 80%), if preset in the monitoring time, the actual bandwidth demand sampled value that sampling obtains is higher than the current signatory bandwidth value of user more than 80%, then determine the current signatory bandwidth deficiency of user.
In the mode of the signatory bandwidth deficiency that above-mentioned two kinds of definite users are current, adopt the processing situation of packet in the real-time monitor user ' business data flow, to estimate the actual bandwidth requirements of Operational Visit, compare to judge with user's signatory bandwidth whether signatory bandwidth is not enough, and do reference with the actual bandwidth demand that monitors, recommend only band width service bag to the user, therefore, can improve real-time and accuracy that band width service pushes.In addition, among this embodiment signatory bandwidth whether not enough determination methods be applicable to and have wide range of applications the Business Stream of all protocol types.
In a kind of method embodiment that pushes band width service provided by the invention, described basis is the statistics of actual bandwidth demand sampled value repeatedly, and the implementation that obtains the actual bandwidth requirements of described business data flow can have following two kinds:
(1) obtains maximum in a plurality of described actual bandwidth demand sampled values, with the actual bandwidth requirements of the maximum in a plurality of described actual bandwidth demand sampled values as described business data flow.
(2) obtain the mean value of a plurality of described actual bandwidth demand sampled values, with the mean value of a plurality of described actual bandwidth demand sampled values actual bandwidth requirements as described business data flow.
Need to prove, when definite current signatory bandwidth deficiency of user, in the time of need being higher than the band width service of described signatory bandwidth value to this user's propelling movement, if when network congestion, recommend the high bandwidth business to the user, can't reach bandwidth after then the user orders and promote effect, experience thereby influence the user.For example: the user bandwidth 1M that contracts, the business demand bandwidth is 2M, but has only 256K because of the busy actual access bandwidth that should business of network, presses such scheme, and system can send the band width service pushed information of high bandwidth bag to the user, and the user also can't promote bandwidth after ordering.In order to address this problem, in the method embodiment of another kind of propelling movement band width service provided by the invention, before pushing the band width service that is higher than signatory bandwidth value to the user, at first need to obtain the load condition of current network, when described network is idle, push the band width service that is higher than described signatory bandwidth value to described user.
During concrete the application, can pass through wireless access network (Radio access network, the current load condition of the real-time requester network of built-in or external probe RAN).
Thus, in the embodiment of the invention, when the user is high bandwidth service propelling object, need meet the following conditions simultaneously:
(1) user is that potential band width service pushes object;
(2) the current signatory bandwidth deficiency of user;
(3) the residing network of user is idle load condition.
In the above-mentioned implementation, make a strategic decision whether push the service package that bandwidth promotes to the user according to the resource occupying situation, particularly, only when network is idle, just recommend the high bandwidth business packet to the user, thereby, guarantee in time to reach the purpose that promotes bandwidth after the user orders, can improve the accuracy that band width service pushes.
In the embodiment of the invention, can pass through Short Message Service Center (Short message service center, SMSC), multimedia messaging center (Multimedia messaging service center, MMSC), email server and terminal door (On-device portal, ODP) form of server issues the band width service package informatin to the terminal use, the current signatory bandwidth deficiency of prompting user, more professional acceleration of set meal bag realization of high bandwidth ordered in recommendation, and presents the bandwidth bag of recommendation.And, after the band width service pushed information is issued to the terminal use, provide the real-time order of electronic channel to the user carries out band width service, so that ordering new high bandwidth, the user overlaps after the meal the bandwidth real-time update.
Further understanding for the ease of to technical solution of the present invention is elaborated to specific embodiments of the invention below by concrete application scenarios.
Referring to Fig. 2, for provided by the invention first pushes the application scenarios of band width service.Under this application scenarios, all Operational Visits of Client-initiated are carried out width monitoring, namely the user class band width service pushes, and the flow process of concrete propelling movement band width service comprises:
(0) analyzes the assessment models of setting up band width service propelling movement object with the band width service supplying system, the band width service potential by off-line analysis identification pushes object, and specific implementation can comprise any or wherein any two or three the combination in following 3 kinds of modes:
(0a) analysis is gone up the attribute of user information of gathering with the band width service supplying system to CRM, for example: and information such as the band width service set meal type of name, sex, age, occupation, user gradation, order, as the source data of analyzing bandwidth service propelling object;
(0b) analysis is gathered user traffic data with the band width service supplying system to probe, for example gathers at Gn mouth, Gi mouth, with the source data of data on flows as analysis bandwidth service propelling object;
(0c) (Online Charging System OCS) goes up the collection charge information, with the source data of charge information as analysis bandwidth service propelling object to Online Charging System with the band width service supplying system in analysis.
(1) during PDP context activation, PCEF goes up request user initial policy to PCRF, that is: obtain the current signatory bandwidth situation of user, PCRF is user traffic flow generation strategy rule and user's actual bandwidth demand monitoring parameter is added in the policing rule, by the Gx interface policing rule is sent to PCEF, simultaneously the not enough detection event of bandwidth and issue PCEF by the Gx interface.PCEF and wireless network are finished resource reservation alternately, and IP-CAN carries foundation, the actual bandwidth demand monitoring parameter in the Write strategy rule, and startup is to the monitoring of the not enough event of bandwidth.In this step, the function of PCRF needs to strengthen, and the Gx interface between PCRF and the PCEF need be expanded.
Actual bandwidth demand monitoring parameter in the policing rule specifically can comprise:
Policing rule numbering: be used for policing rule of unique identification;
The agreement class indication: the protocol class that sign this rule is suitable for, the policing rule of user class adopts the agreement wildcard, such as: utilize the sign of " ALL " to represent that this strategy is suitable for all Business Streams of user, specifically can realize by the Extended Protocol field;
Upstream bandwidth: expression user's maximum uplink bandwidth;
Downlink bandwidth: expression user's maximum downstream transmission bandwidth;
QoS(Quality of service, service quality) class letter: be used to indicate the hierarchical resource that wireless network distributes;
The width monitoring duration: the time of width monitoring is carried out in expression;
The width monitoring sampling period: all period interval of the number of dropped packets of user service data stream and the number-of-packet statistics that success is handled are carried out in expression;
Upstream bandwidth monitoring threshold: expression user's signatory uplink bandwidth value;
Downlink bandwidth monitoring threshold: expression user's signed descending bandwidth value;
Judgement ratio: in the expression width monitoring duration, determine to be higher than in the actual bandwidth demand sampled value ratio of the current signatory bandwidth value of user, be optional parameter.
Part width monitoring parameter in the policing rule, comprise: monitoring duration, the width monitoring sampling period, on/downlink bandwidth monitoring threshold, judgement ratio, generated according to user's signatory bandwidth, operator's configuration by PCRF, have only the user need to be configured to monitoring just can in rule, carry these width monitoring parameters.
For example: operator carries out the width monitoring parameter configuration at user A, B and C on PCRF, and concrete parameter configuration form is as shown in table 1:
Table 1 user class width monitoring parameter configuration
In the table 1, protocol type is ALL, represents that this monitoring parameter is applicable to all Business Streams of this user; The signatory non-operator of bandwidth of user manual configuration, by the distribution of services system (for example: CRM/Provision) be issued to PCRF.
When certain user is configured to need to carry out monitoring, must provide simultaneously and continue to monitor duration, width monitoring sampling period, up-downgoing and whether monitor switch, judgement ratio, can arrange according to the operation situation and monitor upstream and downstream bandwidth simultaneously or only monitor downlink bandwidth, when certain user does not need to carry out width monitoring, do not provide the width monitoring parameter in the policing rule.Usually, the upstream and downstream bandwidth monitoring threshold that issues equals user's signatory bandwidth.
(2) user initiates the Operational Visit request;
(3) PCEF finishes the charging authentication operations, carries out the bandwidth control strategy of Business Stream.
The actual bandwidth requirements of PCEF monitor user ', compare with signatory bandwidth value, be higher than signatory bandwidth value if find the actual bandwidth requirements, then report the not enough event of bandwidth to PCRF, and in event, carry corresponding policing rule numbering and user monitor calculate in the period in fact/the downlink bandwidth demand.
Particularly, by the number of dropped packets of user service data stream in the statistics width monitoring sampling period and the number-of-packet that success is handled, calculate and obtain the current repeatedly actual bandwidth demand sampled value of business data flow in this sampling period of user, and repeatedly carry out actual bandwidth demand sampling in the width monitoring time presetting, and then, according to presetting in the width monitoring time the repeatedly statistics of actual bandwidth demand sampled value, obtain the actual bandwidth requirements of described business data flow.
Particularly, if width monitoring found that, in the duration of presetting the monitoring time definition, measure to obtain the peak bandwidth requirements be higher than the current signatory bandwidth value of user and (determined by last/downlink bandwidth monitoring threshold parameter, as: the downlink bandwidth monitoring threshold is 1M), then determine the current signatory bandwidth deficiency of user.
Perhaps, when judging that signatory bandwidth is whether enough, increasing a judgement ratio (determines by judging scale parameter, as: 80%), if preset in the monitoring time, the actual bandwidth demand sampled value that sampling obtains is higher than the current signatory bandwidth value of user more than 80%, then determine the current signatory bandwidth deficiency of user.
Can obtain the maximum in the described actual bandwidth demand sampled value, with the actual bandwidth requirements of described maximum as described business data flow; Also can obtain the mean value of described actual bandwidth demand sampled value, with the actual bandwidth requirements of described mean value as described business data flow.
(4) PCEF gives PCRF with the not enough reporting events of bandwidth, and carries the actual bandwidth demand that corresponding policing rule is numbered and the user calculated in the monitoring period in event;
(5) PCRF is by real-time interface notification analysis and band width service supplying system user's signatory bandwidth deficiency, notification message comprises: Subscriber Number, professional numbering (business of unique identification is optional value), up actual bandwidth requirements and descending actual bandwidth requirements.
(6) after analysis is received the not enough notice of bandwidth of PCRF with the band width service supplying system, carry out user bandwidth service propelling strategy intelligent decision, the decision-making factor comprises:
Whether the user is that potential high bandwidth business packet band width service pushes object;
By the current load condition of the real-time requester network of built-in or external probe of RAN, judge whether current network is idle condition;
Whether user's current signatory bandwidth is not enough;
When above-mentioned three decision-making factors all were affirmative acknowledgement (ACK), the band width service that the user is the high bandwidth business packet pushed object;
(7) analyze the band width service pushed information that sends bandwidth set meal bag with the band width service supplying system to the user.
The band width service pushed information sends and can send by channels such as note, multimedia message, email, ODP.The bandwidth bag of recommending mates according to the set meal of user's actual bandwidth demand contrast operator issue that PCRF reports, and matches only set meal as the bandwidth bag of recommending, and matching strategy is disposed according to actual operation demand by operator.As: the signatory bandwidth of user A is 1M, and the user A actual bandwidth demand that PCRF reports band width service propelling movement platform is 3.5M, and the bandwidth that matches operator is that the acceleration set meal D of 4M meets the band width service pushing condition.
(8) SMSC, MMSC, email server or ODP server issue the wide service propelling information of band width service band to the terminal use, the current bandwidth deficiency of prompting user, more professional acceleration of set meal bag realization of high bandwidth ordered in recommendation, and presents the bandwidth bag of recommendation.
(9) user initiates the subscription request of the high bandwidth set meal bag of recommendation by electronic channels such as SMSC, MMSC, email server or ODP servers.
(10) SMSC, MMSC, email server or ODP server are initiated subscription request to OCS.
(11) OCS finishes the order operation to the bandwidth bag, and finishes the order of the PCC strategy that new bandwidth set meal bag is comprised by real-time interface notice PCRF.
(12) after PCRF receives and orders notice, initiate strategy modification, generate new policing rule according to new order relations, and by the Gx interface New Policy is issued to the PCEF execution.
(13) PCEF promotes user's access bandwidth according to the New Policy rule adjustment user's who issues bandwidth resource allocation.
