Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the technical field that charge information is provided in the wireless access network system.
Background technology
Extensive use along with the flourish and wireless network of internet service, GPRS network (General Packet Radio Service, GPRS), 3G, microwave access global intercommunication network (Worldwide Interoperability Microwave Access, WiMAX) and back 3G (Beyond 3G B3G) waits wireless system to obtain a large amount of application and concern.The increase of number of users and the increase of user's request provide new demand for wireless access network system: requirement can be supported the multiple business of big capacity, big data quantity and different service quality requirement.
Wireless access network is mainly finished provides business to provide Packet Service between network and the mobile subscriber terminal to transmit or the function of route.How to add up the user's data amount that offers/registration fee service time information and be a very important aspect in the communication system, do not consider in the Access Network other with the irrelevant internal unit situation of chargeing under, we are the function that example (but the technology that this patent was provided includes but not limited to the application in the WiMAX system) illustrates each network element with WiMAX charging network structure system shown in Figure 1.
Accessing business network (Access Service Networt, ASN): ASN is defined as the network function set that the wireless access service is provided for the WiMAX user terminal, ASN has comprised base station (Base Station, BS) and wireless access network gateway (Access Service Network GateWay, ASN-GW) network element.
ASN mainly provides following function:
The function of BS:
-BS and mobile subscriber terminal are provided, and (Mobile Subscribe Station, L2 MSS) connects
-RRM
-measure and power control
The compression and the encryption of-the data of eating dishes without rice or wine
The function of ASN-GW:
-provide client functionality for MSS authentication function
(Network Service Provider, network NSP) find and select in-support network services provider
-the Relay function (as IP address assignment) of L3 information is provided for MSS
-RRM
Except above-mentioned functions, can also comprise following optional function:
Switch in-the ASN
-MSS paging and location management
Tunnel management between the-ASN-CSN is equivalent to the external agent (FA) in the mobile IP technology
The registration of-vision location.
(Connectivity Service Network, CSN): CSN is defined as to the WiMAX terminal IP is provided Connection Service to connect service network.
CSN mainly provides following function:
The IP address assignment of-MSS
-Internet inserts
-AAAproxy or server
-based on user's authorization control
-ASN is equivalent to the home agent (HA) in the mobile IP technology to the tunnel of CSN
-WiMAX user's charging and the clearing between the operator, accounting server shown in the figure or charging proxy are mainly finished this function
Tunnel under the-roaming condition between the CSN
Switching between the-ASN
-various WiMAX services (as location-based business, multi-medium multi-packet broadcasting and broadcasting service, IP Multimedia System business).
MSS:MSS is a mobile subscriber terminal, and the user uses this devices accessing WiMAX network.
From data surface, the grouping busihess data bag of descending MSS from the HA of CSN by the Interface R3 between the ASN-GW HA and the ASN (being referred to as anchor ASN-GW), be sent among the ASN, and send on the MSS through the R6 interface between inner ASN-GW of ASN and the BS and the R1 interface between BS and the MSS data MSS by ASN-GW.If the ASN-GW (being referred to as to serve ASN-GW) of the BS that ASN-GW that links to each other with HA among the CSN and control MSS insert is not simultaneously, the grouping busihess data of descending MSS newspaper from the HA of CSN by the Interface R3 between the ASN-GW HA and the ASN, be sent among the ASN, and send on the MSS through the R6 interface between the inner anchor ASN-GW of ASN and the Interface R4, ASN-GW and the BS that serve between the ASN-GW and the R1 interface between BS and the MSS data MSS by anchor ASN-GW.Upstream data then is delivered to the CSN along opposite path from MSS and reaches end subscriber.
As mentioned above, the data path of corresponding uplink and downlink is arranged all for each Business Stream of each MSS in the interface of ASN inside, these all can be set up according to the qos requirement of each Business Stream and the employing mode of data path when each Business Stream is set up.When this service ending, when just Business Stream is ended, just need to discharge corresponding data path.For charge system, may need classification to charge for user's different business, that is to say, will be discriminatively in the charge information that reports accounting server/agency the charge information of this user's different sessions be collected and reported.And be moved when causing the position to change as the user, may require reporting of uninterrupted charge information owing to the continuity of session for data traffic and Session Time, even the variation of accounting server has taken place, preferably do not need to produce the process that the charging that causes because move stops/beginning at the accounting server end, just the charge information sign of receiving in the accounting server termination to this session of this user will remain unchanged.Like this, for any one session of MSS, keep representing at the accounting server end before ending therein with this charging identifier always.Avoid having caused chargeing continually stopping because moving, charging identifier must be redistributed, the process such as begin of chargeing.
Yet make the BS that inserts it that variation take place when MSS moves, Accounting Client will be ended the charging to this session so, generate new charging identifier then, again to this session charging.When Accounting Client is ended this session charging, will notify accounting server or notify accounting server by charging proxy, the charging of this charging identifier is ended; Accounting Client produces charging identifier again then; Notify accounting server then or notify accounting server, to the beginning charging process of new charging identifier by charging proxy.
Having caused like this charges continually stops, charging identifier must be redistributed, processes such as charging begins, make that charging bill and the ground thereof of MSS are complicated and tediously long, and in fact a plurality of charge information items all will be arranged for same session, charge and user's CDR inquiry all is very disadvantageous for operator.
Present IETF RFC3580 has proposed to identify all sessions of a MSS by Acct-Multi-Session-Id, and specifically identifies session by Session-ID.For a MSS, its Acct-Multi-Session-Id is unique, and the unique identification (such as MAC Address) of the access point (BS) in the time of can be by initial access the, the MAC Address of MSS and the timestamp when setting up this Acct-Multi-Session-Id (first session just begins) are at first represented.So no matter which access point MSS moves under, can not rebulid and change this Acct-Multi-Session-Id again.Though not clear and definite, also we can say in moving process, unless session stop, otherwise also remain unchanged corresponding to the session identification Session-ID of each session always.Guaranteed so finally only to have a usage data record (UDR) for a session.
But this method is not clearly after moving, if after new access point (BS) inserts, processing method when increasing session newly, particularly the Accounting Client at this MSS changes in (forwarding the target Accounting Client to from the source Accounting Client), how to handle charging identifier and for the building method of the sign of the session that increases newly.And this technology and failing considers to carry charging problem under a plurality of user situations at MSS, when a MSS has a plurality of user, can't distinguish each user by Acct-Multi-Session-Id.
Summary of the invention
The present invention proposes to provide in a kind of wireless access network system the method for charge information, in order to solve the problem that charge information can't uninterruptedly be provided after the Accounting Client that has MSS in the prior art changes.
The inventive method comprises:
A, when the source Accounting Client is set up the session of user terminal, be that described session produces a session identification;
B, when described user terminal when described source Accounting Client changes to the target Accounting Client, described source Accounting Client sends to described target Accounting Client with the session identification of described user terminal;
C, described source Accounting Client or described target Accounting Client report accounting server according to described session identification with charge information, are used to upgrade the station message recording.
Further comprising the steps of after the described steps A:
A1, when described user terminal increases a session under the Accounting Client of described source, described user terminal increases a session identification.
Further comprising the steps of behind the described step B:
B1, when described user terminal increases a session under described target Accounting Client, described user terminal increases a session identification.
Described session identification comprises timestamp and the sequence number that unique identification marking of unique identification marking of described source Accounting Client, described user terminal, described session are set up.
Unique identification marking of described source Accounting Client can be the MAC Address of source Accounting Client, or the network identification mark of source Accounting Client; Unique identification marking of described user terminal can be the MAC Address of user terminal, or the network access Identifier of user terminal.
Comprise that also the unique identification marking by the source Accounting Client, unique identification marking of user terminal, the timestamp of session foundation constitute the group sign of many sessions, be used to identify the session of same user terminal, group sign and described sequence number by described many sessions constitute described session identification.
When described user terminal increased session identification, the group of the described many sessions in the session identification of described increase sign was constant, and described sequence number changes.
When one of them session stop of described user terminal, described Accounting Client discharges the resource of the session identification correspondence of described session, keeps the corresponding resource of group sign of many sessions of described session; And/or when all sessions of described user terminal stopped, described Accounting Client all discharged the session identification of described all sessions and the corresponding resource of group sign of many sessions.

Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
As shown in Figure 2, in wireless access network system, comprise MSS101, accounting server 104 and a plurality of Accounting Client 102, each Accounting Client comprises a user terminal session identification memory cell 103, be used to store the session identification of described user terminal, the session identification of MSS comprises unique identification marking of Accounting Client, unique identification marking of this MSS, timestamp and the sequence number that session is set up, comprise a user terminal station message recording memory cell 105 in the accounting server, the station message recording that is used to store described MSS.
As shown in Figure 3, be the flow chart that the present invention supports Acct-Multi-Session-Id and Session-Id simultaneously, as seen from the figure, mainly may further comprise the steps:
S101, support the situation of Acct-Multi-Session-Id and Session-Id simultaneously for Accounting Client and accounting server, when Accounting Client is set up first session of MSS at needs, produce one can the unique many sessions of the overall situation group sign Acct-Multi-Session-Id, this sign can comprise unique identification marking (for example MAC Address or network identification mark etc.) of this Accounting Client, (this timestamp is consistent with the purpose of timestamp among the RFC3580 with the timestamp of setting up for unique identification marking of MSS (for example user's network access Identifier NAI etc.), be in order to prevent when this Accounting Client restarts, generate the group sign Acct-Multi-Session-Id of same session more than again, and the group of these many sessions sign Acct-Multi-Session-Id does not also temporarily end, will cause over-charge like this), also produce simultaneously one by Acct-Multi-Session-Id derive from also can the unique session identification Session-Id (for example Acct-Multi-Session-Id adds sequence number) of the overall situation.
S102, for the session that after this this user increases, then Acct-Multi-Session-Id is constant, Session-Id the inside sequence number changes and gets final product.
S105, when MSS ends certain session, Accounting Client only discharges the resource of this Session-ID correspondence, and with the advice of charge information accounting server of this session.
If the session stop that S106 is all, then the resource of Acct-Multi-Session-Id and Session-ID correspondence all discharges, and the session information of all corresponding termination reports accounting server.Wherein charge information comprises the communication flows information (byte number, datagram number etc.) of this session and/or session persistence or the like.If after this have new session to begin again, then repeat above-mentioned step.
S103, as MSS because move when having produced the replacing of Accounting Client, if there is the agreement of mutual trust between Accounting Client originally (being referred to as the source Accounting Client) and the new Accounting Client (target Accounting Client), all session informations so, comprise that Acct-Multi-Session-Id and Session-ID and other necessary information all will be transferred in the target Accounting Client by the source Accounting Client, all ongoing sessions can't be interrupted/stop to charge like this.
If S104 increases the session of this MSS in this case again newly, so according to present Acct-Multi-Session-Id and the composition rule of Session-ID, new session is distributed Session-ID, and Acct-Multi-Session-Id is still consistent with original session.
S105, when MSS ends certain session, Accounting Client only discharges the resource of this Session-ID correspondence, and with the advice of charge information accounting server of this session.
If S106 all sessions in the destination client have all been ended, then the resource of Acct-Multi-Session-Id and Session-ID correspondence all discharges, and the session information of all corresponding termination reports accounting server.
When the new session of this MSS is set up, then handle according to above-mentioned steps, but produce unique identification marking that can use the target Accounting Client in the composition rule of Acct-Multi-Session-Id and Session-ID this moment, because can not guarantee the sign of the Accounting Client when whether new Accounting Client can also keep the most initial the access, and the information of the Accounting Client when there is no need to re-use and preserve the most initial the access, do not get rid of certainly yet and preserve and the sign of the Accounting Client when using the most initial the access makes up session identification.
When if MSS moves the replacing that has produced Accounting Client, the agreement that does not have mutual trust between Accounting Client originally (being referred to as the source Accounting Client) and the new Accounting Client (target Accounting Client), so then will end all session record, and original Acct-Multi-Session-Id and Session-ID are no longer valid at the source Accounting Client; And in the target Accounting Client, then can produce Acct-Multi-Session-Id and Session-ID again, but in the composition rule of these signs, use unique identification marking of target Accounting Client at each session of this user.
As shown in Figure 4, for the Accounting Client of only supporting Session-ID and accounting server, flow process is as follows:
When S201, Accounting Client are set up first session of MSS at needs, producing one can the unique Session-ID of the overall situation, and no longer include generation and the maintenance process of Acct-Multi-Session-Id, and can be separate for the structure of each Session-ID.Session-ID has comprised unique identification marking (for example MAC Address or the network identification mark etc. of this Accounting Client, the sign of the Accounting Client in the time of herein can inserting for the initial beginning also can be the sign of the Accounting Client that begins this session is chargeed), unique identification marking of user (for example user's network access Identifier NAI etc.), the timestamp of setting up and sequence number (in this case, timestamp can be the time that this session is set up, also can be all identical with the time of first session foundation).
S202, the session that after this increases for this user, Session-Id the inside sequence number changes.
S205, when MSS ends certain session, Accounting Client discharges the resource of this Session-ID correspondence, and with the advice of charge information accounting server of this session.Wherein charge information comprises the communication flows information (byte number, datagram number etc.) of this session and/or session persistence or the like.If after this have new session to begin again, then repeat above-mentioned step.
S203, as MSS because move when having produced the replacing of Accounting Client, if there is the agreement of mutual trust between Accounting Client originally (being referred to as the source Accounting Client) and the new Accounting Client (target Accounting Client), all session informations so, comprise that Session-ID and other necessary information all will be transferred in the target Accounting Client by the source Accounting Client, all ongoing sessions can't be interrupted/stop to charge like this.
If S204 increases the session of this MSS in this case again newly, new session is distributed Session-ID.When MSS ended certain session, Accounting Client only discharged the resource of this Session-ID correspondence, and with the advice of charge information accounting server of this session.
When the new session of this MSS is set up, then handle according to above-mentioned steps, but produce unique identification marking that can use the target Accounting Client in the composition rule of Session-ID this moment, because can not guarantee the sign of the Accounting Client when whether new Accounting Client can also keep the most initial the access, and the information of the Accounting Client when there is no need to re-use and preserve the most initial the access, do not get rid of certainly yet and preserve and the sign of the Accounting Client when using the most initial the access makes up session identification.
When if MSS moves the replacing that has produced Accounting Client, the agreement that does not have mutual trust between Accounting Client originally (being referred to as the source Accounting Client) and the new Accounting Client (target Accounting Client), so then will end all session records, and original Session-ID is no longer valid at the source Accounting Client; And in the target Accounting Client, then can produce Session-ID again, but in the composition rule of these signs, use unique identification marking of target Accounting Client at each session of this user.
If the method for structure Acct-Multi-Session-Id and/or Session-ID can only cause these signs just local unique, method so of the present invention also can be used in reporting of the uninterrupted charge information of this regional area support, guarantees that promptly the charging identifier of session is constant.And the new Accounting Client that inserts as the mobile subscriber during not at this regional area (when perhaps entering this regional area) from the outside all will cause redistributing of charging identifier, just can't support the uninterrupted charge information of the overall situation to report in this case, stop/redistributing the process of chargeable session sign/charging beginning and can occur chargeing.
Illustrate the specific embodiment of the present invention below:
Accounting Client begins in session, conversation end and periodically report charge information, perhaps prepaid user's charging correlated condition (run low for user's amount such as network allocation, Accounting Client is once again to the server application etc.) also can report charge information when arriving.The ID of charge information and session can report up together when reporting at every turn, and charging and session id could be one by one on deserved like this.Each when Accounting Client reports the charge information of this session, by Acct-Multi-Session-Id and Session-ID, just can find the record of this session uniquely at accounting server, thereby upgrade in time this station message recording.
The Acct-Multi-Session-Id and the Session-ID of first session of MSS (supposing to be designated [email protected]) under Accounting Client 1 (MAC Address is 00-10-A4-23-19-C0) are respectively:
[email protected] and 00-10-A4-23-19-C0-bob@gprs.cnmobile.cn-AF-23-83-C0-76-B8-44-E8-01, wherein timestamp is AF-23-83-C0-76-B8-44-E8, and sequence number is 01.
Increase a session for 1 time newly at Accounting Client then, Acct-Multi-Session-Id is constant, and the Session-ID of new session is:
00-10-A4-23-19-C0-bob@gprs.cnmobile.cn-AF-23-83-C0-76-B8-44-E8-02, wherein sequence number changes 02 into.
It is each like this when Accounting Client reports the charge information of second session of this MSS, by Acct-Multi-Session-Id and Session-ID (00-10-A4-23-19-C0-bob@gprs.cnmobile.cn-AF-23-83-C0-76-B8-44-E8-02), just can find the record (second session of this MSS) of this session uniquely at accounting server, thereby upgrade this session charging record in time.
And at every turn when Accounting Client reports the charge information of first session of this MSS, by identical Acct-Multi-Session-Id and the Session-ID of first session (00-10-A4-23-19-C0-bob@gprs.cnmobile.cn-AF-23-83-C0-76-B8-44-E8-01), just can find the record (first session of this MSS) of this session uniquely at accounting server, thus the station message recording of upgrading this session in time.
When MSS moves to new Accounting Client 2 (MAC Address is 00-12-B2-14-23-DE) in first session time, Accounting Client 1 will send to Accounting Client 2 to the Acct-Multi-Session-Id of MSS and [email protected] 3-C0-76-B8-44-E8 and 00-10-A4-23-19-C0-bob@gprs.cnmobile.ch-AF-23-83-C0-76-B8-44-E8-01.Accounting Client 2 will just can find the record (first session of this MSS) of this session at accounting server uniquely by Acct-Multi-Session-Id and Session-ID, thus the station message recording of upgrading this session in time.
After MSS moved to new Accounting Client 2, when increasing a session newly, Acct-Multi-Session-Id was constant so, and the Session-ID of new session is:
[email protected] 44-E8-03, wherein sequence number is 03.
And at every turn when Accounting Client 2 reports the charge information of the 3rd session of this MSS, Session-ID by identical Acct-Multi-Session-Id and the 3rd session (00-10-A4-23-19-C0-bob@gprs.cnmobile.cn-AF-23-83-C0-76-B8-44-E8-03), just can find the record (the 3rd session of this MSS) of this session uniquely at accounting server, thereby upgrade the charging record of this session in time.
When MSS ends all sessions, increase the session of this MSS then newly, then produce the Acct-Multi-Session-Id of this session again, the Acct-Multi-Session-Id and the Session-ID of this session correspondence of this MSS are respectively:
[email protected] and 00-12-B2-14-23-DE-bob@gprs.cnmobile.cn-AF-23-83-C0-77-B8-44-E8-01, wherein timestamp is AF-23-83-C0-77-B8-44-E8.
And at every turn when Accounting Client 2 reports the charge information of this new session of this MSS, by new Acct-Multi-Session-Id and Session-ID (00-12-B2-14-23-DE-bob@gprs.cnmobile.cn-AF-23-83-C0-77-B8-44-E8-01)
Just can find the record (the new session of this MSS) of this session uniquely at accounting server, thus the station message recording of upgrading this session in time.
In addition, charge information is reported the step of accounting server, also can charge information be reported accounting server by charging proxy.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
