Description

Charging method and prepayment client based on the base station from home system

Technical field

The present invention relates to the communications field, in particular to a kind of charging method and prepayment client based on the base station from home system.

Background technology

For higher service rate being provided to the mobile subscriber and reducing the investment of using the needed expense of high rate services, reducing the carrier network deployment; simultaneously; in order to remedy the deficiency that existing distributed cellular radio communication system covers; usually can in existing communication network, dispose base station from home, as replenishing to macro base station.The base station from home operated by rotary motion is used in places such as family, Administrative Areas.Base station from home is a kind of small-sized, lower powered base station, has advantages such as practicality, convenient, low-power output.

Fig. 1 is the schematic diagram according to the communication network model that comprises base station from home of correlation technique, as shown in Figure 1, the communication network model of base station from home comprises base station from home, security gateway, IAD, authentication authorized charging server, anchor point datapath function, prepaid server PPS (Prepaid Server is called for short PPS).

Base station from home can be linked into IAD by security gateway.Security gateway can close with IAD and establish also and can set up separately with IAD.The main effect of security gateway is the link safety that ensures between base station from home and the IAD.

Authentication authorized charging server (Authentication Authorization andAccounting Server, abbreviate aaa server as) be the critical function facility in the communication network, be used to realize control and the management of Virtual network operator to data, user, Certificate Authority is provided, the account service and the service of chargeing, common and collaborative works such as access to netwoks control, gateway server, database and user profile catalogue.The major function of anchor point authentication device (AnchorAuthenticator abbreviates AA as) is to provide the access authentication service to portable terminal when portable terminal networks; After portable terminal networks, move back net before, be in charge of and safeguard the contextual information of portable terminal.Usually the anchor point authentication device is placed in the IAD.

Anchor point datapath function (Anchor Data Path Function abbreviates A-DPF as) is another important function that communication network possesses.No matter how the portable terminal in the network switches in each base station, and all come the data (upstream data) of self terminal all can finally converge to the anchor point datapath function of this terminal, and then are further transmitted (for example, sending to Internet); All mail to this terminal data (downlink data) also all can at first be sent to this anchor point datapath function, further sends to terminal by the anchor point datapath function again.Usually the anchor point datapath function also is placed in the IAD.Anchor point authentication device and anchor point datapath function can be arranged in same IAD, also can be placed in different IAD (as shown in Figure 1).

Billing function is a kind of important Core Feature in the communication system, and charging can be divided into online charging (that is pre-payment) and two kinds of charge mode of offline charging (that is, pay in the back).Online charging comprises multiple charge mode again, for example, charge by flow, by charge often, by service billing (such as, two kinds of different charging methods are used in voice call and visual telephone).

PPS and prepayment client (Prepaid Client, be called for short PPC) be two essential functional entities that realize online charging, both charge to user's online to finish in cooperation: PPS at first is converted into the active user account balance quota (this quota is meant the spendable data traffic of user or the spendable duration of call of user etc.) of some, then the part in the above-mentioned quota is distributed to terminal, and notify PPC this part quota; PPC then is responsible for coming the monitoring user business according to the quota that acquires, and when this part quota is about to use up (for example, the user is current to have used 80% the data traffic used or 80% the duration of call used), PPC general's notice arrives PPS; After this, PPS can reallocate a part of quota to terminal.So repeatedly, find that until PPS all quotas all use up (that is, active user account balance deficiency), at this moment, PPS will notify PPC interruption user's business, and notify the user with the user account information that Sorry, your ticket has not enough value.

When disposing online billing function, the general and aaa server of PPS closes to be established, and at this moment, can be regarded as the function that aaa server itself has PPS; PPS also can set up separately with aaa server, needs suitable interface between them at this moment.PPC then resides on the anchor point authentication device.When anchor point authentication device and anchor point datapath function were positioned at same IAD, PPC also resided on the datapath function, at this moment simultaneously, services such as PPC can use that datapath function provides, come the professional operating position (for example, flow, duration etc.) of monitoring user according to quota; When the anchor point authentication device is placed in different IADs with the anchor point datapath function, for realizing pre paid functionality, also need resident one to be referred to as the PPA functional entity (in Fig. 1, not identifying) of (Prepaid Agent is called for short PPA) in the anchor point datapath function.At this moment, be responsible for professional operating position according to the quota monitoring user by this PPA, and with relevant information by the PPC transfer, send to PPS.

In existing base station from home system, three kinds of dissimilar base station from home are arranged, be respectively: closed mode (CSG-CLOSDE) base station from home, mixed mode (CSG-OPEN) base station from home and open mode (OPEN) base station from home.The closed mode base station from home is meant to have only the affiliated closed subscriber group (CSG) member's of this base station from home user just can insert this base station from home and enjoy the business that this base station from home provides; The open mode base station from home is meant that Any user can insert this base station from home; The mixed mode base station from home is meant and allows CSG user and other users to insert, but can according to the user whether belong to CSG tabulate distinguish different user types, realize differential service quality handle (as, CSG user has higher service priority, has better service quality and class of service).

Reduce the cost of investment that carrier network is disposed in order to arrive, and the purpose that reaches the satisfaction (higher service rate, lower business is used rate) that improves the user and use business, operator need use the base station from home system.

Because base station from home need be bought and arrangement (macro base station does not need the user to buy and settles) by the user, therefore in order to attract user and encouragement user to use base station from home widely, operator need provide otherness to charge and serve for the user who uses base station from home.This otherness is embodied in: use the expenses standard of base station from home visit to be lower than the expenses standard of using the macro base station accesses network; Use the corresponding different charging policy of dissimilar base station from home accesses network, for example use dissimilar base station from home correspondences differently expenses standard, corresponding different charge mode (for example, closed mode base station from home correspondence by charge often, open mode base station from home correspondence charges by flow).

But, the base station type that uses when existing charge system is not related to the injection terminal customer access network (all having only macro base station in the existing network), therefore, in existing network, introduce after the base station from home system, existing charge system can't be known the type of the base station of the current use of terminal use, can't serve for the user provides otherness to charge by carrier-supporting-carrier.Like this, can cause the user that the satisfaction of using the base station from home accesses network is descended, perhaps losing interest, (nobody can be ready oneself to purchase base station from home and be placed among the own home, but same expense when still needing Zhi Fuyu to use macro base station), can not reach operator effectively attracts the user, encourages the user to use the purpose of base station from home widely, and cause the base station from home business to carry out smoothly, until carrying out.

Wherein, above-mentioned base station from home comprises one of following: closed mode base station from home, mixed mode base station from home, open mode base station from home.

Particularly, PPC is by inserting request message or other message with base station type information, and/or user type information, sends to PPS.Wherein, inserting request message comprises one of following: the access request message in the radius protocol, access request message, the credit control request information in the Diameter.

PPC is with base station type information, and/or user type information, it is one of following that the trigger condition that sends to PPS comprises: the quota that terminal initial networks, prepaid server is terminal distribution uses up or is about to use up, the serving BS or the serving BS type of terminal change, the user type of terminal changes, prepayment client receives the pre-payment request; For example, PPC find PPS be the quota of terminal distribution use up or be about to use up (as, used 80% quota, reached threshold value), PPC finds that current serving BS or the serving BS type of terminal changes, PPC finds that the user type of terminal changes.

At PPC with the base station type information of the serving BS of terminal and/or the user type information of terminal, send to before the PPS, this method also comprises: PPA sets up request message from base station from home/base station by pre-established request message of data channel or data channel and obtains base station type information, and/or user type information; PPA is with base station type information, and/or user type information sends to PPC; Particularly, when initial network entry, PPA obtains base station type information and/or user type information from serving BS; When switching, PPA obtains base station type information and/or user type information from target BS.

In addition, PPC can also obtain base station type information from base station from home/base station by one of following message, and/or user type information: but the pre-Attach Request message extended authentication of terminal agreement (Extensible Authentication Protocol abbreviates EAP as) is transmitted message, CMAC key count update request message, context information request message, the pre-established request message of data channel, data channel and is set up request message.Wherein, pre-Attach Request message of terminal and EAP forwarding message is to be used in the initial network entry process, corresponding to serving BS; It is to be used at handoff procedure that CMAC key count update request message, context request message, the pre-established request message of data channel, data channel are set up request message, corresponding to target BS, wherein, pre-established request message of data channel and data channel are set up the scene of corresponding PPC of request message and PPA unification.Then, PPC is by inserting request message with the base station type information that gets access to, and/or user type information sends to PPS.

After PPC sends to PPS with the user type information of the base station type information of the serving BS of terminal and/or terminal, PPS will receive base station type information and/or user type information, and be that terminal is carried out charging policy according to base station type information and/or user type information, wherein, carrying out charging policy for terminal comprises: for terminal is selected charging rate (carrying out quota converts) and/or is the different charge mode of terminal selection.

In addition, with base station type information and/or user type information, when sending to PPS, also that terminal is the current remaining quota of PPC sends to PPS at PPC.Wherein, this remaining quota be PPC from this locality or PPA obtain.

By this embodiment, PPC sends to PPS with the base station type and/or the terminal use active user type of terminal use's Current Serving BTS; PPS can be according to above-mentioned serving BS type, and/or user type information, for this terminal use carries out corresponding charging policy, can attract and encourage the user to use base station from home widely, can be according to the type of the presently used base station of terminal use, it is the type (macro base station of serving BS, dissimilar base station from home), come to serve for the user who uses base station from home provides otherness to charge, can solve after existing network is introduced the base station from home system, can't provide above-mentioned otherness to charge to the user serves, and then can cause the user that the satisfaction of using the base station from home accesses network is descended, until losing interest, and finally cause the base station from home business to carry out smoothly, even problem such as can't carry out.

In actual application, can also be by the user type (CSG member or non-CSG member) under the current terminal use of notice PPS, being embodied as the user provides otherness charging service.For example, CSG member is during by closed mode base station from home or mixed mode base station from home accesses network, obtains lower expenses standard or according to duration based accounting; Non-CSG member is during by open mode base station from home or mixed mode base station from home accesses network, obtain higher expenses standard or according to charge on traffic etc.

Be described in detail below in conjunction with the implementation procedure of example the embodiment of the invention.

Embodiment one

Fig. 2 is according to the current serving BS type of the PPC of the embodiment of the invention one notice PPS terminal, and/or the interaction diagrams of the method for the current user type of terminal, as shown in Figure 2, comprises that following step S202 is to step S206:

Step S202:PPC sends to PPS and inserts request message (AAA message).

Carry out in the process of initial network entry in terminal, PPC need send above-mentioned access request message to PPS, this message is carried the pre paid functionality that PPC supports, be used for and PPS consults the prepayment capabilities method, and to require PPS is that terminal (terminal use) is distributed initial quota (Quota); At this moment, this message is also carried the serving BS type of the terminal that PPC gets access to, and/or the current user type of terminal that gets access to of PPC.

After terminal networks, PPC can also be when finding that PPS is about to use up for this user's allocated quota (for example, used quota 80%), send above-mentioned access request message to PPS, this message was carried and can be indicated the indication which quota need be replenished this moment; At this moment, this message is also carried the serving BS type that above-mentioned PPC gets access to, and/or user type; In addition, this message quota of portability terminal (terminal use) current residual also.

After terminal networked, PPC can also find the current serving BS of terminal, or the serving BS type sends above-mentioned access request message to PPS when changing (for example, terminal switches to base station from home from macro base station); At this moment, this message is also carried the serving BS type that above-mentioned PPC gets access to, and/or user type; In addition, this message quota of portability terminal current residual also.

After terminal networks, PPC can also be when finding that the current user type of terminal (terminal use) changes (for example, the serving BS of terminal is the mixed mode base station from home, manage by CSG, the user type of terminal becomes CSG member by non-CSG member), send above-mentioned access request message to PPS; At this moment, this message is also carried the serving BS type that above-mentioned PPC gets access to, and/or user type; In addition, this message quota of portability terminal current residual also.

, when PPS sends the base station type information of serving BS, can in above-mentioned AAA message, increase B parameter STYPE, and make BSTYPE=0 represent macro base station (MacroBS) at PPC; BSTYPE=1 represents open mode (OPEN) base station from home; BSTYPE=2 represents mixed mode (CSG-OPEN) base station from home; BSTYPE=3 represents closed mode (CSG-CLOSED) base station from home.Can make also that BSTYPE=0 is a default value, when even above-mentioned AAA message was not carried B parameter STYPE, the default service base station type was a macro base station.Perhaps, adopt another mode, in above-mentioned AAA message, increase B parameter STYPE=0 and represent macro base station (Macro BS); BSTYPE=1, SUBTYPE=1 represent open mode (OPEN) base station from home; BSTYPE=1, SUBTYPE=2 represent mixed mode (CSG-OPEN) base station from home; BSTYPE=1, SUBTYPE=3 represent closed mode (CSG-CLOSED) base station from home.Equally, can make also that BSTYPE=0 is a default value, implication and last with.

, when PPS sends user type information, can in above-mentioned AAA message, increase parameter USERTYPE, and make USERTYPE=0 represent non-CSG member (Non-CSG Member) at PPC; USERTYPE=1 represents CSG member (CSGMember).Can make also that USERTYPE=0 is a default value, when even above-mentioned AAA message was not carried parameter USERTYPE, the default user type was non-CSG member.

Above-mentioned access request message (AAA message), the Access-Request message in the radius protocol for example, the AA-Request message in the Diameter, perhaps Credit-Control-Request.

Need to prove, according to actual needs, above-mentioned serving BS type information, user type information can be used separately, also can combine use.

Step S204:PPS obtains the type of above-mentioned serving BS, and/or user type, and is that terminal (terminal use) is used (carry out, select) different charging policy.

Carry out in the process of initial network entry in terminal, PPS can obtain the type of Terminal Service base station from above-mentioned access request, and/or user type.At this moment, PPS can be according to the serving BS type, and/or user type, is that terminal is selected different charging policy.For example, select to carry out according to charge on traffic, according to duration based accounting for terminal (terminal use); Perhaps/and, for terminal (terminal use) is selected different charging rate etc.Wherein, according to this charging policy, PPS is that terminal (terminal use) is carried out the quota conversion;

After terminal networked, PPS can also receive above-mentioned access request from PPC, as described in step S202, had multiple condition and triggered PPC to PPS transmission access request message.PPS can therefrom obtain above-mentioned serving BS type, and/or user type.At this moment, PPS can be according to the serving BS type, and/or user type, the change charging policy, and carry out the quota conversion for terminal again.For example, PPS can find the serving BS type, and/or user type is carried out aforesaid operations relatively when the state of record changes before.In addition, PPS can also carry out together in conjunction with the quota of obtaining the terminal current residual from above-mentioned access request when re-executing the quota conversion for terminal.

Be that terminal is when pressing duration and chargeing (Duration Based Accounting) hereinafter with PPS, carry out quota and be scaled example, illustrate that PPS is according to the serving BS type, and/or user type, for the user carries out different charging policy methods, provide the purpose of differentiated charging service to be reached for the user.

Suppose that active user's account balance is 100 units, above-mentioned PPS is that terminal is carried out the quota conversion, following two examples according to the serving BS type:

If macro base station A., PPS is converted into 100 unit durations (rate is 1, and is higher) with remaining sum; If base station from home, PPS is converted into 200 unit durations (rate is 1/2, and is lower) with remaining sum.

If macro base station B., PPS is converted into 100 unit durations (rate is 1, and is the highest) with remaining sum; If the open mode base station from home, PPS is converted into 150 unit durations (rate is 2/3) with remaining sum; If the mixed mode base station from home, PPS is converted into 200 unit durations (rate is 1/2) with remaining sum; If the closed mode base station from home, PPS is converted into 300 unit durations (rate is 1/3, and is minimum) with remaining sum.

Suppose that active user's account balance is 100 units, above-mentioned PPS comes to carry out quota for terminal according to user type and converts, in the following example:

C. if the terminal use is with non-CSG member's role access network (for example, using non-CSG member role by macro base station, open mode base station from home, mixed mode base station from home accesses network), PPS is converted into 100 unit durations (rate is 1, and is higher) with remaining sum; If the terminal use is with CSG member's role access network (for example, using CSG member role by closed mode base station from home, mixed mode base station from home accesses network), PPS is converted into 200 unit durations (rate is 1/2, and is lower) with remaining sum

Suppose that active user's account balance is 100 units, above-mentioned PPS comes to carry out the quota conversion for terminal in conjunction with serving BS type and user type, in the following example:

D. the serving BS of terminal is a macro base station, the certain right and wrong CSG member of user type this moment, and then user type can classify as non-CSG member, and PPS is converted into 100 unit durations (rate is 1, and is the highest) with remaining sum; The serving BS of terminal is the open mode base station from home, the certain right and wrong CSG member of user type this moment, and PPS is converted into 150 unit durations (rate is 2/3) with remaining sum; The serving BS of terminal is the mixed mode base station from home, and then if terminal is not CSG member's (that is, user type right and wrong CSG member) of this base station from home, PPS is converted into 150 unit durations (rate is 2/3) with remaining sum.If terminal is CSG member's (that is, user type is CSG member) of this base station from home, PPS is converted into 300 unit durations (rate is 1/3) with remaining sum; The serving BS of terminal is the closed mode base station from home, and at this moment, user type must be CSG member, and PPS is converted into 300 unit durations (rate is 1/3, and is minimum) with remaining sum.

By above-mentioned example (A to D) as can be seen, the conversion of quota is actually according to current and carries out for the rate of terminal appointment, and rate then specified by charging policy.

Step S206:PPS returns the access success message to PPC.

It is terminal (terminal use) allocated quota that the access success message can carry PPS.This allocated quota generally is the part of all quotas of having of this user.For example PPS is converted into 100 unit durations (step S204, example C) with the remaining sum of 100 units, that is, all quotas that the user has are 100 unit durations; And in this step, the PPS wherein allocation of quota of 10 unit durations gives terminal, and is delivered to PPC.

PPS is the terminal distribution quota returning to PPC when inserting successfully, generally is used for following several scene (continue to use example, PPS is the quota of terminal distribution 10 unit durations):

E. be the initial quota of terminal distribution, generally occur in terminal and carry out when initially inserting.At this moment, PPC will know allow terminal in following 10 unit interval (as, 10 hours) the accesses network business;

F. be that terminal replenishes the quota of current residual, when generally occurring in quota that PPC finds current terminal and soon using up (for example, also remaining 4 hours), PPC replenishes quota to the PPS application.The reallocate quota of 10 units of PPS is given terminal, and then this moment, PPC had the quota of 14 units.

Certainly, in the present invention, as described in step S202, PPC is finding the serving BS type of terminal, and/or user type also can send the request of access to PPS when changing.At this moment, after execution of step S204 (quota conversion), PPS also can replenish quota for terminal.

What need supplementary notes is, the example that example A to D is lifted among the step S204 can be regarded as in terminal and carries out in the process of initial network entry, and PPS is according to the serving BS type of terminal, and/or user type, terminal use's account remaining sum converted by quota converts the example of quota to.In fact, same principle also can be applied in other scenes.For example, when PPC finds current terminal quota deficiency, perhaps PPC finds above-mentioned serving BS, and/or user type is when changing.

At this moment, PPC need be with the quota of terminal current residual, and above-mentioned serving BS type, and/or user type sends to PPS; PPS takes out current rate, and the quota of current residual (remaining quota that comprises the PPC notice, and the quota that also not have distribution to go down that keeps of PPS) is converted into the user account remaining sum; PPS determines current rate (as described in example A to D among the step S204), and account balance is converted into quota again according to new rate; PPS is that terminal is replenished quota (as described in example F among the step S206).

Below the scene described based on above-mentioned example C, said method is described.Suppose the user type right and wrong CSG member that terminal is current, this user's quota is 100 unit durations (rate is 1, and the user account remaining sum is 100 units) during initial network entry; The PPS 10 unit durations that have been terminal distribution during initial network entry, 90 unit durations are also grasped in PPS this locality.

G. after a period of time, terminal has been used 6 unit durations; At this moment, variation has taken place in the user type of terminal, has become CSG member's (for example, switch to base station from home from macro base station, and terminal being the CSG member of this base station from home) from non-CSG member; As above-mentioned, PPC need send to PPS with relevant information, is 4 unit durations comprising the quota of terminal current residual.PPS can know that current terminal remaining quota is 94 unit durations, and the corresponding account remaining sum is 94 units (rate is 1); Because the user type of current terminal has become CSG member, then PPS is converted into 188 unit durations (rate is 1/2) again with above-mentioned 94 unit remaining sums.Then this moment, total quota of terminal is 184 unit durations; PPS can also replenish quota for terminal this moment, for example, replenishes the quota of 10 unit durations again, and then the quota that has among the PPC this moment is 14 unit durations.

Certainly, the method that above-mentioned example (G) is described equally also is applicable to above-mentioned example A to D, and its principle is identical, and processing method also is similarly, does not repeat them here.

All to illustrate according to duration based accounting, identical principle also can be used the charge mode with other to above-mentioned example (A to G), as, according to charge on traffic (Volume BasedAccounting), principle is identical, repeats no more.

Need to prove that above-mentioned example all is suitable for for the embodiment of the invention, only in certain embodiments, by the function of PPA replacement PPC, and PPC is still essential identical with principle as agency mutual between PPA and the PPS (for example, embodiment two).
