Description
Technical field
The present invention relates to a kind of wireless data communication monitoring system and method, relate in particular to business monitoring and the credit management of user in radio communication.
Background technology
Along with being surging forward of data value-added service, each mobile operator is before 3G arrives, all strengthened investment in wireless data service, how to guarantee investor's running income, prevent the arrearage of user data service, carrying out user's credit monitoring, is that each big operator does not have the basic problem that solves for many years.
The implementation that present each mobile operator adopts the data user to insert when the user roams with visiting, the access control point of this moment is at the GGSN (GGSN on visit ground, Gateway GPRSSupport Node), and user's management data is stored in ownership place, so use the charging of data service to monitor in real time to the roamer, can only take other billing schemes, charge such as the BOSS system, be that after falling ticket by the strange land deduct fees in transmission recurrence possession, in time supervisory user inserts behavior, cause subscriber arrearage, especially the malicious owing fee data volume is big more, and operator's loss is big more.The 3G network that looks to the future simultaneously can be greatly developed data service, and it is carried out content charging, the content charging strategy is to define on GGSN, if adopt visit ground access way, then the roamer can not enjoy the content rate of this province definition, is unfavorable for carrying out of data service.
GPRS (GPRS) network is mainly by GPRS serving GPRS support node (SGSN, ServingGPRS Support Node), GGSN (GGSN), charging gateway (CG) and name server network elements such as (DNS) form, wherein SGSN is responsible for GPRS user's access monitoring.GGSN is the interface of GPRS net and external packet data net (as: Internet, enterprise-specific net etc.).DNS resolves to the IP address of corresponding GGSN with the Access Point Name (APN) of user terminal, for SGSN provides routing iinformation, so that the user is linked in the correct outer data network.
The Access Point Name (APN) that user terminal is provided with indicates the outer data network that the user inserts.Be divided into two classes by purposes:
A kind of is all to support the APN that the external data network that inserts is distributed for the whole network, also claims general APN, and shape such as WAP-Access, this type of APN do not comprise user's home zone domain information; Another kind of APN distributes APN (enterprise's private network inserts) for the external data network of non-the whole network access, also claims regional APN, and shape such as isp.com.bj, this type of APN comprise user's home zone domain information.
Because the characteristics of China Mobile's network, be considered as roaming between different the province but use identical network No., therefore the general APN that the whole network is unified can't distinguish the GGSN in different provinces, and mobile data user's access point is mainly located the parsing of APN by name server (DNS).The roamer that general APN is set at present navigates to the GGSN that visits the defense sector through dns resolution and inserts, thereby causes the reality of roaming data user's visit ground access.The roamer of setting area APN then can navigate to the GGSN access of ownership place through dns resolution.
At the 3G communication document 3GPP TS of International Standards Organization 23.060 appendix As (APN and GGSNSelection) APN parsing and user are inserted in the normal process, APN (S) relation signatory in APN (R) that among the 3GPP TS23.060 user terminal is provided with and the attaching position register (HLR) has following regulation:
| APN(R)： | Be provided with | Be provided with | Empty | Empty |
| APN(S)： | Be provided with | Symbol under unified control | Symbol under unified control | Be provided with |
| Both are provided with condition: | APN(R)＝APN(S) | |||
| The result: | APN(R) | APN(R) | The default APN of SGSN | APN(S) |
The refusal that the packet data protocol (PDP) that regulation all will cause terminal to be initiated for other APN combinations beyond the form in the standard activates.Resolve and selection course for whole APN, as shown in accompanying drawing 2, when the APN of reporting of user (R) is correct signatory APN, SGSN can carry out operator's tag extension to APN (R), by APN NI (operator logo)+OI (operator's sign) APN (R) is expanded, and deliver to DNS and inquire about.From above normal process as can be seen, for the APN of two kinds of common form of user terminal situation (the general APN of shape such as WAP-Access and the regional APN of shape such as isp.com.bj) is set, the domain name of the request analysis that SGSN finally sends to DNS is:
WAP-Access.MNC<mnc>.MCC<mcc>.gprs
isp.com.bj.MNC<mnc>.MCC<mcc>.gprs
Fig. 1 is existing wireless data users connecting system structure chart, and GPRS serving GPRS support node (SGSN) is finished data user's access control standard feature.Insert through GGSN that dns resolution navigate to visit ground roamer that general APN is set this moment, roam into Shanghai as Beijing user on the figure after, can only be connected to external data network by the GGSN in Shanghai, and can not get back to the GGSN of Pekinese.Thereby the reality that the visit ground that causes the roaming data user inserts.

Execution mode one
As shown in Figure 6, in step S1, whole judgement flow process meets existing standard.SGSN receives the correct APN (R) that the domestic user reports, and comprises the APN complete form that has HPLMN operator sign, and SGSN follows execution in step S21.In step S21, at first by the built-in judgment means of SGSN, judge whether APN (R) is general APN, the general APN that perhaps has operator's sign, if not, then be regional APN, it is carried out shape expand as " regional APN+HPLMN OI ", report name server (DNS) to resolve then, Query Result is sent into step S3; If general APN, the general APN that perhaps has operator's sign, then by the built-in expanding unit of SGSN, APN (R) is carried out the information of home location expansion, the number that contains user ascription area information is extracted from travelling carriage integrated services digital network (MSISDN) number, be to extract its 3-9 position 1XXH0H1H2H3 at present, and append on the APN (R), to report name server (DNS) to resolve as " general APN.1XXH0H1H2H3.mnc001.mcc460.gprs ", analysis result is sent into step S3 then.In step S3, if Query Result returns mistake, SGSN returns Active PDP Context Reject to the terminal use, means wireless access request failure.If name server (DNS) correctly resolves to Internet protocol (IP) address of GPRS gateway support node (GGSN), SGSN initiates Create PDPContext Request connection request to this GGSN, means that the user can correctly be linked in the wireless network.
GPRS serving GPRS support node (SGSN) also carries out judgement and the information of home location expansion of reporting of user APN (R) except finishing standard feature such as data user's access control.In APN judged, whether SGSN can identify reporting of user APN (R) and can distinguish fully and join general APN, perhaps has the general APN of operator's sign.Be the WAP-Access form, or WAP-Access.MNC＜mnc .MCC＜MCC the .gprs form.In the information of home location expansion, SGSN extracts 3-9 position 1XXH0H1H2H3 in user's the Mobile Subscriber International ISDN Number, and expands to above the general APN (R), and then reports dns resolution; To regional APN, i.e. isp.com.bj form, SGSN can only carry out operator's tag extension according to standard.In a word, require SGSN to be to the APN extend type that DNS reports:
General APN.1XXH0H1H2H3.mnc0001.mcc0460.gprs;
Zone APN.mnc0001.mcc0460.gprs.
Attaching position register (HLR) provides normal GPRS user contracting data storage, and the GPRS user contracting data is as follows:
To each provincial dns server configuration data requirement be:
The correspondence of " general APN+ this province 1XXH0H1H2H3 section " and this province GGSN IP;
The correspondence of " this province zone APN " and this province GGSN IP.
To national root dns server configuration data requirement be:
The correspondence of " general APN+ each province 1XXH0H1H2H3 section " and each province DNS IP;
The correspondence of " zone, each province APN " and each province DNS IP.
Execution mode two
As shown in Figure 7, in step S1, whole judgement flow process meets existing standard.SGSN receives the correct APN (R) that the domestic user reports, and comprises the APN complete form that has HPLMN operator sign, and SGSN follows execution in step S22.In step S22, at first by the built-in judgment means of SGSN, judge whether APN (R) is general APN, the general APN that perhaps has operator's sign, if not, then be regional APN, it is carried out shape expand as " regional APN+HPLMN OI ", report name server (DNS) to resolve then, Query Result is sent into step S3; If general APN, the general APN that perhaps has operator's sign, then by the built-in expanding unit of SGSN, APN (R) is carried out the information of home location expansion, the number that contains user ascription area information is extracted from international mobile station identity number (IMSI), be to extract its 6-15 position (H1H2H3XXXXXXX) and append on the APN (R) at present, to report name server (DNS) to resolve as " general APN.H1H2H3XXXXXXX.mnc001.mcc460.gprs ", analysis result is sent into step S3 then.In step S3, if Query Result returns mistake, SGSN returns Active PDP Context Reject to the terminal use, means wireless access request failure.If name server (DNS) correctly resolves to Internet protocol (IP) address of GPRS gateway support node (GGSN), SGSN initiates Create PDP Context Request connection request to this GGSN, means that the user can correctly be linked in the wireless network.
GPRS serving GPRS support node (SGSN) also carries out judgement and the information of home location expansion of reporting of user APN (R) except finishing standard feature such as data user's access control.In APN judged, whether SGSN can identify reporting of user APN (R) and can distinguish fully and join general APN, perhaps has the general APN of operator's sign.Be the WAP-Access form, or WAP-Access.MNC＜mnc .MCC＜MCC the .gprs form.In the information of home location expansion, SGSN extracts the 6-15 position (H1H2H3XXXXXXX) of user's international mobile station identity number (IMSI), and expands to above the general APN (R), and then reports dns resolution; To regional APN, i.e. isp.com.bj form, SGSN can only carry out operator's tag extension according to standard.In a word, require SGSN to be to the APN extend type that DNS reports:
General APN.H1H2H3XXXXXXX.mnc0001.mcc0460.gprs;
Zone APN.mnc0001.mcc0460.gprs.
Attaching position register (HLR) provides normal GPRS user contracting data storage.
To each provincial dns server configuration data requirement be:
The correspondence of " general APN+ this province H1H2H3XXXXXXX section " and this province GGSN IP;
The correspondence of " this province zone APN " and this province GGSN IP.
To national root dns server configuration data requirement be:
The correspondence of " general APN+ each province H1H2H3XXXXXXX section " and each province DNS IP;
The correspondence of " zone, each province APN " and each province DNS IP.
Execution mode three
Except normal signatory regional APN with have the general APN of area flag, need in CAMEL-Subscription-Information, insert simultaneously to trigger and indicate in the attaching position register (HLR), i.e. "+area flag ", form is as "+bj ".For example the signatory tabulation of Beijing data user's APN is:
As shown in Figure 8, in step S1, whole judgement flow process is expanded existing standard.When SGSN receives the correct APN (R) that the domestic user reports, comprise the APN complete form that has HPLMN operator sign, SGSN follows execution in step S23.After SGSN receives not signatory wrong APN, not that refusal inserts, but judge that further the user is whether in HPLMN, if not at HPLMN, explanation is that other operators are roamed into the user, then refuses its access, if at HPLMN, then SGSN follows execution in step S23.In step S23,, judge whether APN (R) is general APN or the general APN that has operator's sign by the built-in judgment means of SGSN.If not, then SGSN carries out operator's tag extension to it, promptly by APN NI (operator logo)+OI (operator's sign) APN (R) is expanded, and reports name server (DNS) to resolve then, and analysis result is sent into step S3; If general APN or have the general APN of operator sign, SGSN can directly not refuse to insert, but SGSN is by the special field "+area flag " among the inquiry HLR, trigger SGSN general APN is carried out the area flag expansion, report name server (DNS) to resolve with " general APN+ area flag+HPLMN OI " form, analysis result is sent into step S3.In step S3, if Query Result returns mistake, SGSN returns Active PDP Context Reject to the terminal use, means wireless access request failure.If name server (DNS) correctly resolves to Internet protocol (IP) address of GPRS gateway support node (GGSN), SGSN initiates Create PDP ContextRequest connection request to this GGSN, means that the user can correctly be linked in the wireless network.
GPRS serving GPRS support node (SGSN) also triggers sign and extracts and trigger landmark identification except finishing 3GPP specified standard function.In triggering the sign extraction, for the general APN of reporting of user, SGSN is not that simple refusal inserts, but takes out the triggering sign from HLR, and with this this APN (R) is expanded.In triggering landmark identification, for among the HLR with the triggering sign of "+area flag " form, SGSN can therefrom extract user's information of home location, what SGSN not only stipulated in the image scale standard carries out operator's tag extension to APN (R) like that, and carry out the information of home location expansion simultaneously, " area flag " that will extract from trigger sign expands to above the APN (R).
HLR except needs according to the existing subscription data memory requirement, APN tabulation is needed the following form of configuration:
Wherein area flag is according to the abbreviated form of each province.
To each provincial dns server configuration data requirement be:
The correspondence of " the regional sign of general this province of APN+ " and this province GGSN IP;
The correspondence of " this province zone APN " and this province GGSN IP.
To national root dns server configuration data requirement be:
The correspondence of " general APN+ each province area flag " and each province DNS IP;
