Specific embodiment

Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure It is fully disclosed to those skilled in the art.

The embodiment of the invention provides a kind of flow statistical method and gateways, a kind of method, agency service for accessing network Device and system, when mobile terminal network visiting to solve the prior art, need to expend a large amount of data traffic of mobile terminal Technical problem.

The exchange method for the access network that the embodiment of the present invention is introduced, as shown in Figure 1, be the interaction figure of this method, it should Equipment involved in method includes: mobile terminal, the distribution server, proxy server and Resource Server, wherein mobile terminal Such as are as follows: mobile phone, tablet computer etc., the user of mobile terminal are terminal user；The distribution server is mainly used for moving Dynamic terminal provides authentication, selection proxy server；Proxy server is mainly used for having online and exempting from flow permission Mobile terminal provides network access service；Resource Server is usually provided by internet content provider, for utilizing internet Internet resources provide rich and varied Web content for terminal user, such as: video, webpage, picture etc..

Referring to FIG. 2, the exchange method of the access network the following steps are included:

Step S110: proxy server receives the data that mobile terminal accesses network by the network of mobile communication carrier Access request, includes the communication identifier of mobile terminal in data access request, and communication identifier has online and exempts from flow permission；

Step S120: proxy server obtains phase according to the data access request from mobile terminal, from Resource Server The requested date answered；

Step S130: requested date is transmitted to mobile whole by proxy server by the network of mobile communication carrier End；

Wherein, the communication data during above-mentioned mobile terminal network visiting is being flowed through positioned at mobile terminal and agency service When the gateway of the mobile communication carrier between device, if exempting from flow identifier comprising online in communication data, communication data will be by Gateway is completely or partially included in specified services quotient.

Wherein, as a kind of optional embodiment, before proxy server receives data access request, mobile terminal is needed It is determined as it and proxy server of network access service is provided, wherein mobile terminal can be directly communicated mark and send The distribution server, judges whether the communication identifier has by the distribution server and exempts from flow permission, determines its tool in the distribution server It is not otherwise mobile terminal assignment agent server for when exempting from flow permission, being mobile terminal assignment agent server.

Specifically, gateway first obtains mobile terminal and accesses leading in network development process by the network of mobile communication carrier Letter data, and detect in communication data whether comprising online exempt from flow identifier, if comprising, based on online exempt from flow identifier, The corresponding data traffic of communication data is completely or partially included in specified services quotient, wherein mobile terminal is asked in network development process Communication data include that data access request that mobile terminal is sent to proxy server and proxy server are sent out to mobile terminal The requested date sent.And from safety considerations, above-mentioned communication data is transmitted using cipher mode, and gateway can be from communication It is obtained on predeterminated position in data and exempts from flow identifier ciphertext, and be decrypted to flow identifier ciphertext is exempted from, obtain exempting from flux scale Know in plain text, then judge whether exempt from flow identifier in plain text is to preset to exempt from flow identifier, if it is, determining in communication data comprising upper Net exempts from flow identifier.

And the communication identifier of mobile terminal is falsely used in order to prevent, improves the safety of network access, as a kind of optional Embodiment, determine the process of proxy server with continued reference to FIG. 2, the following steps are included:

Step S101: the communication identifier and authentication information of the distribution server reception mobile terminal；

Step S102: communication identifier and authentication information verifying communication identifier of the distribution server based on mobile terminal are It is no have exempt from flow permission；

Step S103: the distribution server determine communication identifier have exempt from flow permission when, be mobile terminal assignment agent Server.

For example, before step S101, mobile terminal can by first pass through in advance registration etc. in a manner of the distribution server bind The communication identifier of mobile terminal, such as: mobile terminal can exempt from traffic service, the distribution server to the distribution server application first After receiving the application of mobile terminal, according to some prerequisites (such as: initiate this application software whether be make a reservation for it is soft Part, the mobile terminal whether used predetermined software, the communication identifier whether specified services quotient registration etc.) determine whether to Flow permission is exempted from the communication identifier distribution of the mobile terminal, if the distribution server, which is determined, exempts from flow power to mobile terminal distribution Limit, then the distribution server can send a UserKey (user password) to mobile terminal and be used as authentication information；Further , the distribution server can then give communication identifier to guarantee that the communication identifier of mobile terminal is not falsely used by other users first An identifying code is sent, after the user of mobile terminal successfully fills in the identifying code, just gives mobile terminal distribution authentication letter Breath；In addition, the access network development process for mobile terminal provide exempt from stream service when, can be not present flow restriction, can also deposit In flow restriction, accumulated in access network development process using more wherein being referred to there is no flow restriction regardless of the mobile terminal Few flow, exempts from flow permission to its offer as long as meeting the requirement for exempting from stream；There are flow restrictions to refer to for movement end It holds and distributes particular flow rate in every section of predetermined time, if mobile terminal, which accumulates the total flow used in access network development process, not to be had Beyond the particular flow rate, then its meet exempt from traffic requirement in the case where, exempt from flow permission to its distribution, and if mobile terminal The total flow used in access network development process is more than particular flow rate, then does not exempt from flow permission to its distribution, such as；For shifting Dynamic terminal can be with the free flow of a month distribution 30M, the free flow of 50M etc..

If mobile terminal needs to access network in turn, such as: detect that the user of mobile terminal starts the behaviour of browser Make, then the communication identifier of oneself and authentication information can be sent to the distribution server by mobile terminal.

In addition, the distribution server provided for mobile terminal network visiting process exempt from stream service when, flow can be not present Limitation, there may also be flow restrictions, wherein there is no flow restrictions to refer to regardless of the mobile terminal is in access network development process Middle accumulation uses how many flow, exempts to exempt from flow permission to its offer as long as stream requires as long as meeting, such as: the distribution server can be Certain mobile terminals device identification (such as: particular vendors production mobile terminal, use the shifting of certain types of operating system Dynamic terminal etc.) setting VIP identity, and then the device identification that is supplied to these mobile terminals is endless exempts to flow；And it is directed to non-VIP User may exist flow restriction, and there are flow restrictions to refer to for the specific stream of distribution in every section of predetermined time of the mobile terminal Amount meets if mobile terminal accumulates the total flow that uses without departing from the particular flow rate in access network development process at it In the case where exempting from stream requirement, exempt from flow permission to its distribution, and if mobile terminal is total used in access network development process Flow is more than particular flow rate, then does not exempt from flow permission to its distribution, such as；It can be exempted from for mobile terminal with a month distribution 30M Take free flow of flow, 50M etc..

In an alternative embodiment, if the distribution server distributes to the free flow of mobile terminal, there are Flow Limits System, then the user of mobile terminal can also obtain the data traffic of the distribution server reward by some activities, such as: movement is eventually Endpoint hits pre-determined advertisement, click predetermined webpage, the predetermined APP of downloading etc., and in this case, the distribution server, which can increase, is The data traffic of mobile terminal distribution, such as: 30M, 40M etc..

In step S102, the authentication information for the communication identifier that the distribution server judgement receives is led to this prestored Whether the authentication information that beacon is known matches, and if matching, illustrates that corresponding mobile terminal has and exempts from flow permission, Otherwise illustrate that corresponding mobile terminal does not have and exempt from flow permission.

In step S103, if the flow permission of exempting from that the distribution server is mobile terminal distribution does not have flow restriction, divide Hair server can directly be its assignment agent server after determining that mobile terminal has and exempts from flow permission, and if The distribution server is that the flow permission of exempting from of mobile terminal distribution has flow restriction, then the distribution server is determining mobile terminal tool It is standby exempt from flow permission after, it is also necessary to judge its residual flow whether more than one threshold value, just give shifting when being more than this threshold value Dynamic terminal distribution proxy server, treatment process is specifically includes the following steps: the distribution server acquisition communication identifier uses and refers to The charging mode for determining service provider carries out the free residual flow information of charging；Communication identifier is judged based on free residual flow information Free residual flow whether be greater than predetermined amount (threshold value of such as front)；When free residual flow is greater than predetermined amount, for movement Terminal distribution proxy server.

Under normal conditions, one of the effect of the distribution server is exactly to count the free residual flow information of communication identifier, in advance If amount is for example are as follows: 0M, 1M, 512K etc. illustrate under normal conditions, to be somebody's turn to do if free residual flow is greater than predetermined amount Exempting from stream residual flow can satisfy the access of this network, so its assignment agent server can be given；And if free residual stream Amount then illustrates under normal conditions that it is impossible to meet the access of this network for the free residual flow no more than if predetermined amount, so Do not give its assignment agent server.

Wherein, the distribution server can be selected when giving mobile terminal assignment agent server from multiple proxy servers It selects the proxy server nearest apart from mobile terminal physical position and distributes to that mobile terminal, also to can choose network load most light The proxy server that proxy server distributes to mobile terminal or selects network delay minimum distributes to mobile terminal etc. Deng, or comprehensively considered using at least two strategies in above-mentioned multiple distribution policies to select, the distribution server is used Which kind of mode is mobile terminal assignment agent server, and the embodiment of the present invention no longer itemizes, and with no restriction.

Wherein, as a kind of optional embodiment, there is no flow restriction in the flow permission of exempting from for mobile terminal distribution In the case where, if mobile terminal, which has, exempts from flow permission, interim verification information (token) use is can be generated in the distribution server In this network access procedure of mobile terminal；Or there are flow restrictions in the flow permission of exempting from for mobile terminal distribution In the case where, if mobile terminal has and exempts from flow permission and mobile terminal has free residual flow, the distribution server Interim verification information can be generated.

In addition, the distribution server is needed some numbers in order to guarantee that subsequent movement terminal can be connected to proxy server According to proxy server is sent to, four kinds of data therein are set forth below and are introduced, it is certainly, in the specific implementation process, unlimited In following four situation.1. the communication identifier of mobile terminal is sent to proxy server by the distribution server；2. the distribution server The communication identifier of mobile terminal, interim verification information are sent to proxy server；3. the distribution server is led to mobile terminal Beacon is known, free residual flow is sent to proxy server；4. the distribution server is by the communication identifier of mobile terminal, free remaining Flow, interim verification information are sent to proxy server.

In addition, the address information of proxy server is also required to be supplied to mobile terminal, wherein the address of proxy server is believed Breath can be sent directly to mobile terminal by the distribution server；It can also be by proxy server in the communication for receiving mobile terminal After mark, mobile terminal is sent it to by the communication identifier of mobile terminal.Step S104 as shown in Figure 2, for by dividing The process for the mobile terminal that the address information of proxy server is sent to by hair server.

After completing above-mentioned preparation, in step S110, if the distribution server in step S101~S103 simultaneously Interim verification information is not distributed for this network access procedure, then mobile terminal will directly carry the data access for exempting from flow identifier Request is sent to proxy server；If the distribution server is assigned in step S101~S103 for this network access procedure Interim verification information, then mobile terminal will flow identifier be exempted from carrying, the data access request of interim verification information is sent to agency Server.

Wherein, exempt from flow identifier can for it is a variety of it is various forms of exempt from flow identifier, be set forth below it is therein two kinds progress It introduces, certainly, in the specific implementation process, is not limited to following two situation.

1. proxy server is after receiving the communication identifier of mobile terminal of the distribution server transmission and is receiving Before the data access request that mobile terminal is sent, default label is sent to mobile terminal, in mobile terminal network visiting process In default label is carried when carrying out data transmission, default label is to exempt from flow identifier.

2. the distribution server is that the IP address of the proxy server of mobile terminal distribution is preset IP address, preset IP address As this exempts from flow identifier.

In step S120, proxy server can be just straight after the data access request for receiving mobile terminal transmission It connects from Resource Server and obtains corresponding requested date, and based on the difference sent before the distribution server to proxy server Information, proxy server can also first carry out some verification process, and three kinds of verification process therein are set forth below and are introduced, when So, in the specific implementation process, following three kinds of situations are not limited to.

1. the data that the distribution server is sent to proxy server include that the communication identifier of mobile terminal and interim verifying are believed Breath, in this case, the data access request that mobile terminal is sent also can include interim verification information, then proxy server exists When legal by interim verification information verify data access request, requested date is obtained from Resource Server.Wherein, agency's clothes Business device matches the interim verification information that mobile terminal is sent and the interim verification information that the distribution server is sent, if matching If success, then illustrates that the data access request is legal, otherwise illustrate that the data access request is illegal.Through the above scheme can Enough guarantee the safety of this network access procedure.

2. the distribution server be sent to proxy server data include mobile terminal communication identifier and free residual stream Information is measured, then proxy server is primarily based on free residual flow information judgement movement after receiving data access request Whether the newest free residual flow of terminal is greater than predetermined amount；When newest free residual flow information is greater than predetermined amount, from money Source server obtains requested date, and if newest free residual flow information is not more than predetermined amount, inform mobile terminal, Allow mobile terminal by other access path access Resource Server (such as: directly by data access request be sent to resource clothes Business device).Through the above scheme, specified services quotient can be made to provide the free data flow of specific quantity to mobile terminal.

Wherein, if judging that the free residual flow of mobile terminal was greater than predetermined amount in the distribution server, clothes are acted on behalf of Device be engaged in when receiving data access request for the first time, does not need to judge newest free residual flow (namely the distribution server hair The free residual flow sent) whether it is greater than predetermined amount；But the data traffic of this network access request consuming is directly counted, so It is subtracted into the data traffic from the free residual flow that the distribution server is sent afterwards, then available newest free data stream Amount；It can be determined whether by judging whether newest free data flow is greater than predetermined amount by data access request in subsequent It is sent to Resource Server.

In addition, proxy server can also the data traffic letter according to spent by preset measurement period statistics mobile terminal Breath, knows that mobile terminal has the newest free residual flow information for exempting from flow permission.

For example, preset measurement period is for example are as follows: preset statistics time interval, preset statistics time interval example Timer can be set in for example 30s, 50s, 1min etc., proxy server, and every prefixed time interval just obtains its statistics Mobile terminal data traffic spent in current time interval, and mobile terminal is obtained most based on the data flux statistics New free residual flow information.

Preset measurement period in another example are as follows: preset statistics flow, preset statistics flow are 512k, 1M etc., generation Reason server can be monitored data traffic spent by the mobile terminal, every to expend preset statistics flow, then basis The preset statistics flow determines the newest free residual flow information of mobile terminal.

Through the above scheme, it can guarantee the newest residual flow information for obtaining mobile terminal in time.

Certainly, proxy server, can also after measurement period counts data traffic information spent by mobile terminal To be sent to the distribution server, the newest free residual flow information of mobile terminal is counted by the distribution server.

Wherein, it after the distribution server obtains data traffic information spent by mobile terminal, can also be sent to move Dynamic terminal is informed in mobile terminal enquiry；Or the distribution server is in the newest free residue for determining mobile terminal After flow information, mobile terminal can also be sent it to, so enable mobile terminal to present flow rate service condition into And a understanding, then select preferable network access policies.Or it is informed in mobile terminal enquiry.

3. the data that the distribution server is sent to proxy server include the communication identifier of mobile terminal, free residual flow Information and interim verification information, in this case, then proxy server is verifying the visit of this data by interim verification information It asks and legal and newest free residual flow information is requested to be greater than predetermined amount, requested date is obtained using Resource Server.Pass through The program can either guarantee the safety of this network access procedure, and can guarantee that specified services quotient only provides to mobile terminal The free flow of predetermined amount.

In step S130, the data during mobile terminal network visiting include upstream data and downlink data, wherein on Row data are the data (namely data access request) that Resource Server is sent to by mobile terminal, and downlink data is by providing Source server is sent to the data (namely requested date) of mobile terminal, wherein at least one in upstream data and downlink data The data traffic of kind data is counted into the data traffic of given server consumption.

For example, comprising exempting from flow identifier, the data access request in the data access request that the mobile terminal is sent Corresponding data traffic is exempted from flow identifier based on described in and is included in the specified services quotient；Exempt from flow another example is: carrying The data access request of mark is sent to after Resource Server, also can be comprising exempting from flux scale in the requested date returned Know, so the data traffic of requested date by based on exempt from flow identifier be included in given server consume data traffic in.

In the specific implementation process, it can be counted by the gateway being set between mobile mobile terminal and proxy server Data traffic in network access procedure.

It is corresponding gateway (or the charge system being connected with corresponding network) In the case where presetting IP for flow identifier is exempted from After the data access request for receiving mobile terminal transmission, the IP of next node corresponding to the data access request is judged Whether it is default IP, if it is default IP, its data traffic is included in the data traffic of specified services quotient, corresponding gateway (or The charge system that person is connected with corresponding network) after the requested date for receiving proxy server transmission, judge the agency Whether the IP of server is to preset IP its data traffic is included in the data traffic of specified services quotient if it is default IP；Needle It is in the case where presetting label to flow identifier is exempted from, corresponding gateway (or the charge system being connected with corresponding network) is receiving After the data access request (or the requested date for receiving proxy server transmission) that mobile terminal is sent, it is judged as this Whether comprising default label in data access request (or requested date), if comprising presetting label, by its data flow Meter enters the data traffic of specified services quotient.

In the specific implementation process, mobile terminal accesses the partial data stream generated in network development process by proxy server Amount is exempted from flow identifier based on described in by Mobile Network Operator and is included in specified services quotient, may exist a variety of situations, under Face is enumerated three kinds therein and is introduced, and certainly, in the specific implementation process, is not limited to following three kinds of situations.

The first, the data traffic of special ratios is counted into the specified services during the mobile terminal network visiting Quotient.

For example, special ratios are for example are as follows: 50%, 70% etc., wherein have during mobile terminal network visiting It is standby when exempting from flow permission (such as: data transmission, which carries, exempts from flow identifier), corresponding gateway (or the charging being connected with corresponding network System) its special ratios is included in specified services quotient, and remaining ratio is included in the communication identifier, and such as: assuming that this net Mobile terminal expends the flow of 10M, special ratios altogether in network access process are as follows: and 50%, then charge system is in charging, by 5M's Flow is included in specified services quotient, and the flow of remaining 5M is included in the communication identifier of the mobile terminal.Certainly, above data is only As an example, it is not intended as limiting.

Second, certain amount of data traffic is counted into the specified services during the mobile terminal network visiting Shang Zhong.

For example, specific quantity is for example are as follows: 10M, 20M etc., wherein have during mobile terminal network visiting When exempting from flow permission, corresponding gateway (or the charge system being connected with corresponding network) terminates it in this access network development process Afterwards, whether the data traffic for judging this access network development process is more than the specific quantity, if being not above, will be owned Data traffic be all included in specified services quotient；If it exceeds will then be not above the data traffic of part if specific quantity It is included in specified services quotient, overage is included in the communication identifier of the mobile terminal.

The third, the data traffic of specific content is counted into the specified services during the mobile terminal network visiting Quotient.

For example, specific content is for example are as follows: text, picture etc., wherein have during mobile terminal network visiting For when exempting from flow permission, corresponding gateway (or the charge system being connected with corresponding network) obtains what access network development process was transmitted Data, then determine the data such as text, picture from the data transmitted of access network development process, and by its corresponding data flow Meter enters in specified services quotient；And it is directed to other kinds of content, and such as: its corresponding data traffic is then included in shifting by video In the communication identifier of dynamic terminal.

It is described to be included in specified services quotient as a kind of possible implementation, comprising: to generate corresponding data flow Expense is calculated as the expense of the account consumption of specified services quotient.

For example, since corresponding data flow has been included in specified services quotient, and mobile communication carrier will not be directed to Primary network access process carries out repetition charging, so corresponding data traffic will not be counted into the mark of the mobile terminal, because , in mobile communication carrier's charging, the expense that can be generated is calculated as the expense of the account consumption of specified services quotient for this, thus It charges to specified services quotient.
