Embodiment
In present cordless communication network technology, contents processing mode for the roamer, two kinds of tupes of main existence: first, the content that the roamer receives is successively passed through the processing of home network and visited network, and the content of roamer's transmission is simultaneously successively passed through the processing of visited network and home network; The second, the content of roamer's transmitting-receiving is only handled at visited network.Prior art only adopts the content that under first kind of pattern the roamer is received to handle, and has the long problem of waste Internet resources, processing delay; Do not propose how to solve the scheme that the roamer receives and dispatches information filtering for second kind of pattern simultaneously.
The embodiment of the invention not only can will be received and dispatched the visited network that regular and synchronized that content filters gets access to the roamer place to this user in roamer's home network, can directly carry out filtration treatment for the content of roamer's transmitting-receiving like this at roaming network, thereby avoided wasting the long problem of Internet resources, processing delay once, can be applicable to above-mentioned roam mode two simultaneously in above-mentioned roam mode.Can also will receive and dispatch the home network that regular and synchronized that content filters gets access to the roamer place to this user in roamer's visited network, can directly carry out filtration treatment for the content of roamer's transmitting-receiving like this at home network, thereby avoided wasting the long problem of Internet resources, processing delay once, met the home domain control thought of IMS in above-mentioned roam mode.
Wherein, the scheme of realization said process comprises step: roamer place second network obtains roamer place first network this user is received and dispatched the rule that content is filtered; According to described filtering rule the content of described roamer's transmitting-receiving is filtered.Wherein, when described second network was visited network, described first network was a home network; When perhaps second network was home network, first network was a visited network.For convenience of description, be home network with first network below, second network is that visited network is that example is described.
The filtering rule that roamer place visited network obtains to roamer's home network is the rule (being defined as publicly-owned rule here) that home network filters all transmitting-receiving contents, if in the home network at this roamer place, exist content corresponding to filter the subscriber and be provided with other filtering rules for this user, then the filtering rule that obtains of visited network also comprises the filtering rule (here be defined as privately owned rule) of information filtering subscriber for this user's setting.Adopt identical total rule if the visited network at roamer place and home network are reached an agreement, then the filtering rule that obtains from home network of visited network only includes corresponding privately owned rule.
Preferably, for the visited network (VN) at roamer place first to this user's home network (HN) obtain filtering rule include but not limited to below two kinds of situations:
First: VN finds that on behalf of user roaming, this Signalling exchange enter present networks, then is triggered to the action of obtaining filtering rule among the HN;
Second: when VN receives the content that the interior perhaps roamer that sends to the roamer sends first, the transmission related content goes for to visited network content filter server (VCS) asks information filtering, VCS inquires this user for the roamer and when not obtaining the filtering rule of this user attaching network, then is triggered to the action of obtaining filtering rule among the HN.
Followingly describe, drive home network content filter server HCS and home network HN into line description as two processing body portion for convenient, but this only be for convenience of description for the purpose of, its HCS still is a network element device among the HN; In like manner also drive VCS and visited network VN into line description as two processing body portion, its VCS still is a network element device among the VN.
As shown in Figure 3, for the present invention obtains the first embodiment processing procedure schematic diagram of filtering rule, wherein processing procedure is as follows:
S10. switch registration, voice/data traffic when switching as the start registration of VN process user, static (dormant) into sequence of operations such as (as change MSC and switch, change PDSN switch, change SGSN switch etc.), VN can parse user's HN address, and to judge the user with this be the roamer, simultaneously according to operation can judge this be the roamer under roaming state for the first time and present networks carry out Signalling exchange.
S11.VN notice VCS obtains the filtering rule that this user is had in its home network, wherein carry this user's sign and the address of its HN in the notification message that VN sends.
The user ID of carrying in the notification message that S12.VCS sends according to VN, inquiring user roaming state record sheet, under the situation that does not inquire this user record, explanation need be arrived among this user's the HN and be obtained the filtering rule that this user has; If inquired this user record, illustrate and in this user's HN, obtained the filtering rule that this user had that this situation then stops this flow process after S13 carries out.
S13.VCS returns response to VN, notice VN has received the notification message among the above-mentioned S11, if VN does not receive this response, retransmit the notification message among the above-mentioned S11 at interval behind the certain hour, if after repeating to send this notification message of stipulated number, still never receive this response, can select termination.
The HN address of carrying in the notification message that S14.VCS sends according to VN to this user's HN request content filtering rule, wherein carries user ID and VCS address in this request message.
S15.HN resolves the request message that VCS sends, find that it is an information filtering rule request message, then the record that whether records this user in the user record table is roamed out in inquiry according to the user ID of carrying in its request message, if there not be the record that writes down then add this user; And then HN is transmitted to home network content filter server (HCS) with this request message that receives.
The user ID inquiring user roaming state record sheet that carries in the S16.HCS basis request message that receives: if do not inquire this user's roaming state record, then add this user's roaming state record, and its roaming identity is changed to roams out, preserve the VCS address of carrying in the request message that receives simultaneously; If HCS inquires roaming identity in this user's the roaming state record for roaming out, but the VCS address of carrying in corresponding VCS address of preserving and the request message that receives is different, illustrate that then this user has roamed into the VN of the current VCS address correspondence that receives from the VN of the VCS address correspondence of former preservation, then the HCS VCS address of having preserved before replacing it with the VCS address that receives; And if the roaming identity that inquires in this user's the roaming state record is not roaming to illustrate that this user has directly roamed into VN from HN, then its roaming identity is changed to and roams out, and the VCS address that receives of preservation.
HCS also will inquire about this user and whether be equipped with privately owned filtering rule, if this user has been set up privately owned rule, also will will go out privately owned rule searching that should the user.
S17.HCS feeds back to VCS with the publicly-owned rule of self all the elements being filtered, if HCS has also inquired this roamer's privately owned filtering rule, then also the privately owned rule that inquires VCS be to be fed back to, user ID and HCS address in this feedback message, also carried simultaneously.
If VCS does not receive this feedback message, then should behind the certain hour of interval, retransmit the request message among the above-mentioned S14, if VCS still never receives the feedback message that HCS sends behind this request message of retransmitting stipulated number, can select terminator.
S18.VCS handles the filtering rule that receives as required and user ID and filtering rule correspondence is kept in the rule database, VCS adds user record in the user roaming state record sheet on the other hand, with user ID corresponding stored HCS address, and this user's roaming identity is changed to is roamed into.About VCS to the handling problem of the filtering rule that receives can but be not limited to be undertaken by following manner:
If at first VCS adopts identical grammer to describe filtering rule with HCS, then need not carry out the identification and the conversion of grammer, if and VCS adopts different grammers to describe filtering rule with HCS, then to carry out the identification and the conversion process of grammer to the filtering rule that receives, to allow VCS and HCS can understand syntax rule mutually; Secondly aspect semantic, directly take for crucial words, if VCS uses identical classify and grading method with HCS, then do not need the filtering rule that receives is carried out semantic identification and conversion, if and VCS uses different classify and grading methods with HCS, then need the filtering rule that receives is carried out semantic identification and conversion process.
VCS filtering rule after the filtering rule that gets access to or the conversion and self filtering rule can be separated store separately and in follow-up filtration treatment to above-mentioned rule call successively (can carry out earlier carry out behind self the filtering rule get access to or change after filtering rule, also can carry out earlier get access to or conversion after filtering rule after carry out self filtering rule), HCS filtering rule after the publicly-owned filtering rule of VCS and HCS filtering rule that gets access to or the conversion can also be merged processing simultaneously, and the content of roamer's transmitting-receiving be carried out filtration treatment based on the filtering rule after merging.
As shown in Figure 4, for the present invention obtains filtering rule and carries out the second embodiment processing procedure schematic diagram of information filtering, wherein processing procedure is as follows:
When S20. visited network received the content of roamer's transmitting-receiving first, the user record table was roamed out in inquiry according to user ID, does not find this user record, then content and the user ID that receives is sent to VCS, and request VCS carries out information filtering.
The user ID inquiring user roaming state record sheet that the S21.VCS basis receives: under the situation that does not inquire this user record, judge the address that to go VN to obtain HN.
S22.VCS wherein carries user ID in this request message to VN request user's HN address.
S23.VN inquires about its HN address according to this user ID, and the HN address that this inquires is returned to VCS.
S24.VCS judges this user for being roamed into the user after receiving this user's the HN address of VN feedback, need arrive among this user's the HN and obtain the information filtering rule.
If judging this user is the local user, then in the user roaming state record sheet, add this user record, put roaming identity and be roaming, stop this flow process and directly use the publicly-owned rule of VCS and mate possible privately owned rule and filter also return results.
The processing procedure of S14～S18 in the processing procedure of follow-up S25～S29 and the above-mentioned Fig. 3 processing procedure is same or similar, specifically sees for details above-mentionedly, does not repeat them here.
S30.VCS matches all filtering rules that this user should follow according to this user ID and (comprises that the user receives and dispatches the filtering rule that content should be followed in HN under roaming state in rule database, if further there is the rule that all transmitting-receiving contents are filtered in VCS, also comprise the rule that this VCS filters all transmitting-receiving contents), and use the filtering rule that matches that this roamer's transmitting-receiving content first carry out filtration treatment; VCS will write down and carry out current point in time that this information filtering handles with as the nearest time of implementation on the other hand.
Content after S31.VCS will filter and this user ID thereof send to VN (wherein VCS can directly feed back to the content after filtering the equipment that sends this content, also can feed back among the VN other and have the equipment of content transmitting capacity).
In addition, in 3GPP R5, R6, IMS is from being incorporated into deeply, be defined as supporting the multimedia service core net of all IP Access Networks, can support any mobile or fixing, wired or wireless IP connectivity accesses network (IP-CAN, IP Connectivity Access Networks).The IMS territory has the characteristic of roaming, no matter the user wherefrom access network can provide service by the S-CSCF (service call conversation control function) that the mode of IMS roaming or IP-CAN roaming is got back to ownership.
As shown in Figure 5, a kind ofly be based on above-mentioned roam mode two, shown in (2) bar dotted line among the figure, (with GPRS is example to the user attached to visit ground IP-CAN, carrying out data via visit ground SGSN, GGSN inserts), the user will be linked into the IMS network by visit ground P-CSCF (Proxy Call Session Control Function), because data channel is all at visited network, the above-mentioned method that corresponding filtering rule is used in the home network of in visited network, obtaining should be adopted, the function of controlled filter application server can be increased at the IMS network by visited network P-CSCF; A kind ofly be based on above-mentioned roam mode just like among the figure shown in (1) the bar dotted line, the user is attached to ownership place IP-CAN (via visit ground SGSN and homing GGSN), IMS user is linked in the IMS network by ownership place P-CSCF, this moment is very convenient, flexible, both can use prior art, also can use above-mentioned visited network to get the method for rule application, can also adopt home network to get the method for rule application (as filtering) at GGSN.
That is to say, the embodiment of the invention proposes and will in roamer's visited network this user be received and dispatched the home network that regular and synchronized that content filters gets access to the roamer place, can directly carry out filtration treatment for the content of roamer's transmitting-receiving like this at home network, thereby avoided wasting the long problem of Internet resources, processing delay once, met the home domain control thought of IMS in above-mentioned roam mode.
Also see also Fig. 6, for roaming based on IP-CAN among Fig. 5 in the embodiment of the invention, ownership place IMS triggers the flow chart that operation layer application server HCS filters the data of turnover GGSN.Specifically comprise:
M61. after the user successfully registered first, H-IMS checked this user's who is downloaded filtering rule, and it is used to control the registration that application server is carried out service application.
M62.H-IMS is according to described filtering rule, generate a third-party registration request, and described third-party registration request mail to HCS, wherein, described register requirement carries user ID, preferably, can also carry VCS address or VN IMS address in the described register requirement, perhaps other represents that this user is in the sign of roaming state.
After M63.HCS receives described register requirement, return 200 (OK) response to H-IMS.
If M64. in step M62, carry VCS address or VN IMS address in the described register requirement, then HCS to VCS request content filtering rule, wherein carries user ID in this request directly or through VN IMS, also may carry the HCS address.
Wherein, if in step M62, do not carry VCS address or VNIMS address in the described register requirement; Then being divided into following three kinds of situations describes:
If HCS is instructed to this user's roaming, but does not provide VN IMS or VCS address, then HCS need carry out the operation of step M64 again after HSS obtains VN IMS or VCS address.
If whether HCS is not instructed to roam, then whether HCS need obtain to HSS and roam, and obtains VN IMS or VCS address when roaming, and carries out the operation of step M64 after confirming to roam again.
If HCS is instructed to not roaming, or confirm not roaming under a last situation, the filtering rule of then confirming this user's correspondence as required has only the information filtering rule of HN, does not have the filtering rule of roaming place before.
M65.VCS takes out its publicly-owned information filtering rule, and corresponding user ID and the HCS address of preserving; Or in the HCS corresponding lists, increase this user ID.
M66.VCS returns its publicly-owned information filtering rule to HCS, wherein also may carry user ID and VCS address.
M67.HCS handles the information filtering rule that receives as required and user ID, VCS address and filtering rule correspondence is kept in the rule database.Wherein, about processing procedure (the possible grammatical and semantic conversion of HCS to the filtering rule that receives, with filtering rule and self the filtering rule separate storage after the filtering rule that obtains or the conversion, so that carry out respectively during follow-up filtration, or and self filtering rule merge the back storage for use in follow-up filtration) appropriate section of step S18 among similar Fig. 3, specifically see for details above-mentionedly, do not repeat them here.
As shown in Figure 7, for the filtering rule among the roamer HN being obtained on the basis that is stored in VN based on the handling process of above-mentioned Fig. 3 or Fig. 4, the embodiment that the content that follow-up subtend roamer sends is filtered handles schematic diagram, wherein:
S40. content source (CR) directly sends to VN (referring to adopt second kind of present roam mode) with content and reception user ID; Perhaps CR at first sends to content and reception user ID this user's HN, HN roams out the user record table according to this user ID inquiry then, find this user record then HN learn that this user has roamed into field network, directly shielding HCS filters the content that CR issues this user, but content and this reception user ID thereof directly CR sent are transmitted to the VN (referring to adopt first kind of present roam mode) that this user roams in.
S41.VN inquires about according to user ID and roams out the user record table, do not find, then content that HN is sent and reception user ID thereof are transmitted to VCS, request VCS filters this content, if VCS can not discern the user ID that CR brings, after then VN also needs to find the user ID that corresponding VCS can discern according to the user ID that CR brings, send to VCS again.
S42.VCS is according to the user ID inquiry roamer state record table that receives, find the record that records this roamer and its roaming identity for being roamed into, then in rule database, mate all the elements filtering rule that this user should follow under roaming state and (comprise that the user receives and dispatches the filtering rule that content should be followed in HN according to this user ID, if further there is the rule that all transmitting-receiving contents are filtered in VCS, also comprise the rule that this VCS filters all transmitting-receiving contents), and use the filtering rule that matches that each transmitting-receiving content of this roamer is carried out filtration treatment; VCS will write down current point in time that each execution information filtering handles with as the nearest time of implementation on the other hand.
Content after S43.VCS will filter and this user ID thereof send to VN (wherein VCS can directly feed back to the content after filtering the equipment that sends this content, also can feed back among the VN other and have the equipment of content transmitting capacity).。
S44.VN determines the recipient address according to receiving user ID, and the content after will filtering is assembled into satisfactory data packet format, sends to reception user (User) then.
Also see also Fig. 8, for based in the handling process of above-mentioned Fig. 6 the filtering rule among the roamer VN being obtained on the basis that is stored in HN, the embodiment that the content that follow-up subtend roamer sends is filtered handles schematic diagram, comprising step:
M80.CR directly sends to HN (such as the GGSN in the home network) with content and reception user ID.
M81.HN sends to HCS with content and the user ID of receiving, request HCS filters this this user's content.
M82.HCS mates all the elements filtering rule that this user should follow on the one hand, and uses the filtering rule that matches that each transmitting-receiving content of this roamer is carried out filtration treatment according to the user ID that receives under roaming state in rule database; HCS will write down current point in time that each execution information filtering handles with as the nearest time of implementation on the other hand.
Content and this user ID thereof after M83.HCS will filter send to HN.
M84.HN determines VN SGSN address according to receiving user ID, and the content after will filtering is assembled into satisfactory data packet format, sends to VN SGSN.
M85.VN sends to content and receives user (User).
As shown in Figure 9, for the handling process based on above-mentioned Fig. 3 or Fig. 4 is obtained the filtering rule among the roamer HN on the basis that is stored in VN, the follow-up process chart that the filtering rule that has obtained is upgraded, wherein in subsequent process, HCS is monitoring self to all transmitting-receiving contents rules (publicly-owned rule) of filtering when changing, and/or the privately owned filtering rule that is set up of roamer triggers filtering rule and upgrades operation (S50) when changing; HCS determines that the change of filtering rule will have influence on that all roaming identities are the user who roams out in roamer's state record table, then according to the VCS address of the corresponding preservation filtering rule after VCS sends change, VCS upgrades the filtering rule among the HN of current preservation with request, carries roamer's sign (S51) in this update inquiry information; The user ID rule searching database that the VCS basis receives, and based on the filtering rule (S52) among the HN of current storage in the filtering rule update rule database after the renewal that receives; VCS returns the renewal success response to HCS, if HCS does not receive this response message, then can behind the certain hour of interval, retransmit the update inquiry information among the above-mentioned S51, if HCS is after the update inquiry information of retransmitting stipulated number, still can not receive the response of VCS feedback, then can consider to stop sending update inquiry information (S53).
Similarly, the replacement of VCS and HCS can be used as based in the handling process of Fig. 6 the filtering rule among the roamer VN being obtained on the basis that is stored in HN among Fig. 9, the follow-up process chart that the filtering rule that has obtained is upgraded, VCS, triggers filtering rule and upgrades operation (S50) when changing all transmitting-receiving contents rules (publicly-owned rule) of filtering monitoring self; VCS is according to the filtering rule of the HCS address of preserving after HCS sends change, and HCS upgrades the filtering rule among the VN of current preservation with request.
As shown in figure 10, for the present invention obtains filtering rule and carries out the 3rd embodiment processing procedure schematic diagram of information filtering, wherein the disposed of in its entirety process of S60～S74 is similar to the S20～S31 processing procedure among above-mentioned Fig. 4, just HCS also will feed back the rule sign corresponding with the filtering rule of feedback to VCS feedback filtering rule the time, VCS also will preserve the rule sign corresponding with this filtering rule when the filtering rule that preservation HCS sends then, wherein filtering rule sign can be a rule ID, also can be that corresponding rule ID and update time, information etc. was combined into can a rule of unique representative sign.Rule identifies the regular obtain manner that does not limit to in the present embodiment and combines the regular obtain manner that triggers in the time of can also being used for detecting this roamer and other situation first.Simultaneously, compare with S20～S31, the clear and definite filtering rule of carrying out self earlier of present embodiment removes to obtain the HCS filtering rule simultaneously, carry out again get access to or conversion after filtering rule.
As shown in figure 11, for the filtering rule among the roamer HN being obtained on the basis that is stored in VN based on the handling process of above-mentioned Figure 10, the embodiment that the content that follow-up subtend roamer sends is filtered handles schematic diagram, wherein:
S80.CR directly sends to VN (referring to adopt second kind of present roam mode) with content and reception user ID; Perhaps CR at first sends to content and reception user ID this user's HN, HN roams out the user record table according to this user ID inquiry then, find this user record then HN learn that this user has roamed into field network, directly shielding HCS filters the content that CR issues this user, but content and this reception user ID thereof directly CR sent are transmitted to the VN (referring to adopt first kind of present roam mode) that this user roams in.
S81.VN inquires about according to user ID and roams out the user record table, do not find, then content that HN is sent and reception user ID thereof are transmitted to VCS, request VCS filters this content, if VCS can not discern the user ID that CR brings, after then VN also needs to find the user ID that corresponding VCS can discern according to the user ID that CR brings, send to VCS again.
S82.VCS is according to the user ID that receives inquiry roamer state record table, finds the record that records this roamer and its roaming identity for being roamed into, and illustrates that VCS calls the content corresponding filtering rule from HCS.
S83.VCS extracts and sends to HCS with the user ID of storage and with the rule sign of the information filtering called rule corresponding stored.
S84.VCS at first uses the rule of self all transmitting-receiving contents being filtered that the content that CR sends is filtered.
The user ID coupling that S85.HCS sends according to VCS is current to filtering rule sign that should user storage, and whether the filtering rule sign that comparison match goes out is identical with the filtering rule sign that VCS sends, if the comparative result difference illustrates that then the filtering rule among the HCS upgrades.
S86.HCS extracts filtering rule after the renewal and corresponding rule sign thereof, returns the Policy Updates response to VCS then, carries user ID in this Policy Updates response, the filtering rule after upgrading and corresponding rule sign thereof; If the comparative result difference among the above-mentioned S85, then HCS upgrades response message to VCS feedback rule; If VCS does not receive this response message, VCS then can behind the certain hour of interval, retransmit the message among the above-mentioned S83, if after this message of retransmitting stipulated number, still can not receive the response of HCS feedback, then can consider to stop sending this message, continue S88 and subsequent step thereof.
S87.VCS is based on the corresponding record of the new filtering rule of HCS feedback and corresponding new regular identification renewal this locality thereof;
S88.VCS matches this up-to-date user information filtering rule that needs use in HN according to user ID in the home town ruling database, and based on the HN filtering rule that matches the content that CR sends is filtered; VCS also will write down the current point in time that each execution information filtering is handled on the other hand, with as the nearest time of implementation.
Content after S89.VCS will filter and this user ID thereof send to VN (wherein VCS can directly feed back to the content after filtering the equipment that sends this content, also can feed back among the VN other and have the equipment of content transmitting capacity).
S90.VN determines the recipient address according to receiving user ID, and the content after will filtering is assembled into satisfactory data packet format, sends to reception user (User) then.
As described in Figure 12, first embodiment that deletes the filtering rule that gets access to for VCS handles schematic diagram, wherein:
S100.VCS is detecting the last content execution filter time distance that the roamer is received and dispatched now above an official hour length, then delete the roaming state record of this user in the user roaming state record sheet, comprise this user's sign, roaming identity, HCS address, time of implementation recently in this roaming state record, may also have and the rule sign of this filtering rule correspondence.Also want the record of this user in the deletion rule database simultaneously, comprise sign and its corresponding filtering rule of this user in this record.
This user's roaming state record carries this user ID and VCS address in the S101.VCS notice HCS deletion user roaming state record sheet in this notification message.
S102.HCS is according to the roaming state record of this user in the user ID inquiring user roaming state record sheet: if the roaming identity in the roaming state record is that the VCS address of roaming out and writing down is identical with the VCS address that receives, then delete its roaming state record; If the roaming identity in the roaming state record is to roam out but the VCS address of writing down is different with the VCS address of receiving, illustrate that then the user has roamed into new VN; If the roaming identity in the roaming state record illustrates that for not roaming this user has come back to HN.
S103.HCS returns the deletion success response to VCS; If VCS does not receive this response message, then can behind the certain hour of interval, retransmit the notification message among the above-mentioned S101, if VCS after this message of retransmitting stipulated number, still can not receive the response of HCS feedback, then can consider to stop sending this notification message.
The record of this user in the user record table is roamed out in S104.HCS notice HN deletion, wherein carries user ID in this notification message.
S105.HN inquires about the record of roaming out this user in the user record table according to user ID, and with its deletion.
S106.HN returns the deletion success response to HCS; If HCS does not receive this response message, then can behind the certain hour of interval, retransmit the notification message among the above-mentioned S104, if HCS after this message of retransmitting stipulated number, still can not receive the response of HN feedback, then can consider to stop sending this notification message.
Similarly, VCS among Figure 12 and HCS replaced can be used as the filtering rule among the roamer VN is obtained on the basis that is stored in HN based on the handling process of Fig. 6, the follow-up process chart that the filtering rule that has obtained is deleted, HCS is detecting the last content execution filter time distance that the roamer is received and dispatched now above an official hour length, or receive that H-IMS registers the releasing message of removing the back initiation, the filtering rule after then the VN filtering rule of this user's correspondence maybe will merge in the deletion rule database reverts to and only is the HN filtering rule.HCS notice VCS deletes the HCS address of its reservation, carries this user ID and HCS address in this notification message.VCS deletes its record according to user ID, or deletes this user ID from the user ID tabulation of HCS correspondence, and returns the deletion success response to HCS.Because Fig. 6 filtering server is deployed in the GGSN position, do not need to notify VN deletion user record afterwards.If this flow process is initiated by H-IMS, then need to reply response.
As shown in figure 13, second embodiment that deletes the filtering rule that gets access to for VCS handles schematic diagram, wherein:
S110.HCS is receiving filtering rule that VCS sends when obtaining request message, if the roaming identity in this user roaming state of inquiry record be roam out and the VCS address of wherein record with receive obtain the VCS address of carrying in the request message when inconsistent, illustrate that this user has roamed into new VN from former roaming place, then HCS triggers the filtering rule that this VCS deletion has got access to;
On the other hand, when if HCS receives the content that requires filtration, the roaming identity of inquiring about in this user roaming state record is not roaming, illustrates that then this user has got back to local network again after the field network roaming, and HCS triggers the filtering rule that the VCS deletion has got access to;
This user's information filtering rule in this user's roaming state record and the rule database wherein comprises this user ID in this notification message in the S111.HCS notice VCS deletion user roaming state record sheet; Comprise roaming identity, user ID, HCS address, information such as time of implementation recently in the roaming state record, wherein roaming identity comprise again be roamed into, roam out, roaming.
S112. in addition, the record of this user in the user record table is roamed out in HCS notice HN deletion, wherein carries this user ID in this notification message.
S113.HN roams out the record of this user in the user record table according to the user ID deletion of carrying in the notification message that receives.
S114.HN returns the deletion success response to HCS, if HCS does not receive this response message, then can behind the certain hour of interval, retransmit the notification message among the above-mentioned S112, if HCS is after this message of retransmitting stipulated number, still can not receive the response of HN feedback, then can consider to stop sending this notification message.
The information filtering rule of this user in HN in this user's roaming state record and the rule database in the user ID deletion user roaming state record sheet that carries in the S115.VCS basis notification message that receives.
S116.VCS is to HCS feedback deletion success response, if HCS does not receive this response message, then can behind the certain hour of interval, retransmit the notification message among the above-mentioned S111, if HCS is after this message of retransmitting stipulated number, still can not receive the response of VCS feedback, then can consider to stop sending this notification message.
As shown in figure 14, for the information filtering technology is applied in the interface schematic diagram of WCDMA R99 system, wherein content filter server (CS) had not only provided the SS7 address of circuit domain but also had provided the IP address of packet domain.CS-1 interface between CS and the SGSN adopts the GTP agreement (to comprise chain of command GTP-C, user's face GTP-U), CS-2 interface between CS and the MSC/VLR adopts the SS7 agreement, CS-3 interface between CS and the HLR has only signaling to transmit, usually adopt the MAP among the SS7, CS-4 interface between CS and the CS adopts GTP agreement (comprising chain of command GTP-C, user's face GTP-U).
As shown in figure 15, be applied in interface schematic diagram for information filtering technology in the embodiment of the invention based on the IMS network architecture.Follow existing ISC interface between CS and the CSCF, follow existing Sh interface between CS and the HSS, CS and IP connect between the Access Network and connect by the CS-1 interface, IP connects the reference point of Access Network and is determined by concrete network condition, can be the GGSN of WCDMA/GRPS, the HA of CDMA2000 etc., connect by the CS-4 interface between CS and the CS.
As shown in figure 16, for the information filtering technology is applied in the schematic diagram of WCDMA R99 system, this system is divided into four major parts: terminal (representative of consumer), Access Network, core net and external network, wherein terminal, Access Network and core net constitute WCDMA R99 system.Usually terminal is mutual by Uu interface and Access Network, and Access Network is mutual by Iu interface and core net.Core net has only identified main network components and interface, wherein MSC/VLR is mutual by CS-2 interface and CS, MSC/VLR is mutual by D interface and HLR, GMSC and HLR are undertaken alternately by C interface, use the SS7 signaling that is carried on the TDM to carry out alternately between MSC/VLR and GMSC and GMSC and the outside PSTN, SGSN and HLR are mutual by Gr interface, SGSN is mutual by gn interface and GGSN, SGSN is mutual by CS-1 interface and CS, GGSN is mutual by Gc interface and HLR, by the Gi interactive interfacing, CS and HLR are by the CS-3 interactive interfacing between GGSN and the exterior I nternet.MSC/VLR and GMSC are the critical piece of circuit domain, and terminal is finished circuit domain service interaction in the WCDMA network by it, perhaps is linked into external circuit territory business networks such as PSTN by it.SGSN, GGSN are the critical piece of packet domain, and terminal is mutual by its packet switch domain service of finishing in the WCDMA network, or are linked into Internet by it.Wherein CS and HLR both be the circuit domain parts services, also were the packet domain parts services.
Based on above-mentioned application network environment, here suppose that CS uses the Common Policy (referring to www.ietf.org website draft-ietf-geopriv-common-policy) of IETF to describe the information filtering rule, use the Semantic mapping table to carry out the coupling and the conversion of different filtering rule semantemes simultaneously, make between the different CS and can correctly discern mutually and the converted contents filtering rule.Illustrate below.
The Common Policy of IETF uses XML to describe, and has defined the delegated strategy framework of relevant application data access control, the clear and definite describing mode of common policy rule, and this common policy framework can expand to other application.Wherein Policy is exactly rule set (Rule Set), and it is made up of a lot of Rule, and each Rule comprises conditional expression (Conditions), operation (Actions) and conversion (Transformations) three parts.Conditions is the set of conditional expression, each conditional expression or be TRUE or for FALSE.When the information filtering request arrives, need be with each Rule coupling among itself and the RuleSet, the Rule that all conditions expression formula of its Conditions part is TRUE is exactly the suitable Rule of this request.Actions is the operation behavior that content is specifically filtered, and Transformations is the retouching operation to the particular content that sends to the user.
Here use the Semantic mapping table to carry out the coupling and the conversion of different filtering rule semantemes, a concrete Semantic mapping table is as shown in table 1 below, in CS, can use database or simple program to express this Semantic mapping table, with this object information that inquiry service is provided and returns matching operation.

2) classifying content is Sex1, or content part comprises XXX or XX or XXXX or XXXXXXX;
Carry out action action for stoping block, be about to information filtering and fall.
Enumerate the specific implementation process that an embodiment illustrates the inventive method below, suppose that user A is based on the F ground contracted user of Chinese WCDMA R99 network, its CS-B place on F ground is provided with the information filtering service.When user A roams into G ground, its WCDMA R99 network by G ground surfs the web, owing to surf the Net by visited network distributing IP address when operator's whole strategy is roaming, so user A is by GGSN-S visit exterior I nternet, G ground content that user A the is received and dispatched process of filtering specifically can be as follows like this:
Obtain filtering rule and information filtering: certain content supplier of Internet network sends to GGSN-S according to the IP address of user A with the content that user A asks; GGSN-S sends to SGSN-S according to the IP address of user A by gn interface, SGSN-S is according to the IMSI of the IP address search user A that receives, and, ask it that content is filtered with the content filter server CS-S that content of receiving and the IMSI that searches send to G ground.
The IMSI that the CS-S basis receives does not inquire the roaming state record of user A, then inquires about the address on home network F ground to the VLR-S on G ground request.VLR-S inquires about the address of its HLR according to this IMSI, and the HLR-B address with F ground returns to CS-S then.CS-S asks the filtering rule of user A to HLR-B, and has the address of oneself, and HLR-B is transmitted to this request the CS-B on F ground.CS-B inquires about its roaming state record according to the IMSI of this user A, finds that its roaming identity is not roaming, and CS-B is changed to it and roams out, and preserves the CS-S address.CS-B sends to CS-S with the publicly-owned filtering rule of self and the privately owned filtering rule and the CS-B address of user A setting.CS-S adds A in user roaming state record, preserve the CS-B address, handles also to preserve and obtains the filtering rule of filtration, and the filtering rule preserved and IMSI are carried out correct related, and the roaming identity of this user A is changed to is roamed into.Since CS-S and CS-B use same grammer and based on classification grade also identical, therefore do not need to carry out the identification and the conversion of syntax and semantics.
If CS-S has inquired the roaming state record of user A according to the IMSI that receives, and roaming identity wherein is for being roamed into, then CS-S matches corresponding filtering rule according to this IMSI in the roaming state record of user A, comprises the publicly-owned filtering rule of CS-S, the publicly-owned filtering rule of CS-B and the privately owned filtering rule of user A;
CS-S has the publicly-owned filtering rule of CS-B and the privately owned filtering rule of user A based on self publicly-owned filtering rule and embodiment, content is filtered, and write down the nearest time of implementation of current time conduct of each filtration treatment.Content and IMSI after CS-S will filter send to SGSN-S.Content after SGSN-S will filter according to this IMSI carries out sending to after the respective handling WCDMA R99 Access Network on G ground, sends to the user A that roams in G ground by it.
Policy Updates are handled: if the publicly-owned filtering rule of CS-B is changed, then CS-B is according to the CS-S address of record in the roaming state record of user A, publicly-owned filtering rule after CS-S sends change, request CS-S carries out Policy Updates to be handled, and wherein carries the IMSI of user A in this request message.CS-S is according to IMSI inquiring user roaming state record, and the roaming identity of finding its record then upgrades the publicly-owned filtering rule of CS-B of original storage for being roamed into the filtering rule that receives.CS-S returns to CS-B and upgrades successful response message.
Redundant rule elimination is handled: CS-S detects the current time and is performed the information filtering processing time apart from the content of the last transmitting-receiving of user A and has surpassed 48 hours of regulation, all records in the roaming state of the CS-S deletion user A record then comprise the filtering rule that gets access to from the CS-B side of former storage.CS-S notice CS-B deletes the roaming state record of user A, carries IMSI and the CS-S address of user A in this notification message.CS-B finds that according to IMSI inquiring user roaming state record wherein the roaming identity of record is that the CS address of roaming out and writing down is identical with the CS address that receives, and then deletes the roaming record of user A.CS-B returns success the deletion response message to CS-S.
As shown in figure 17, for implementing the processing structure chart of system construction drawing that the above embodiment of the present invention constituted and VCS thereof, HCS inside, visited network content filter server (VCS) 100 wherein, can obtain roamer's home network this user is received and dispatched the rule that content is filtered, and the content of this roamer's transmitting-receiving be filtered based on the filtering rule that gets access to; Home network content filter server (HCS) 200, the request of obtaining of sending according to this VCS100, to receive and dispatch the rule that content filters to this user and send to VCS100, the filtering rule that VCS100 may also need to obtain from HCS200 is converted to the grammatical and semantic that self can discern, and based on the filtering rule after the conversion content of roamer's transmitting-receiving is filtered.If store the rule of self all transmitting-receiving contents being filtered among the VCS100, also to filter the content of roamer's transmitting-receiving in addition based on the rule of self the transmitting-receiving content being filtered; VCS100 may need filtering rule of self and the filtering rule that obtains from HCS200 are merged processing in this case, based on the filtering rule after merging the content of roamer's transmitting-receiving is filtered again.If adopt first kind of present roam mode, the content of roamer's transmitting-receiving also needs the processing through home network, therefore HCS200 will shield these contents will be carried out filtration treatment in this case, handle but the visited network that directly by home network these contents is sent to the roamer place carries out information filtering.
In VCS100, acquiring unit 101 obtains to roamer's home network this user is received and dispatched the rule that content is filtered; In HCS200, request receiving element 201 is used for receiving the request of obtaining that the VCS100 of roamer place visited network sends, and wherein this request of obtaining is used to ask this user is received and dispatched the rule that content is filtered; Filtering rule feedback unit 202 is used for according to the request of obtaining that receives of request receiving element 201, and inquiry is received and dispatched the rule that content filters and fed back to VCS100 this user in the rule database 203 of self.
Rule database 102 among the VCS100 stores the filtering rule that acquiring unit 101 gets access to, may also store the rule that VCS100 self filters the transmitting-receiving content in addition in this rule database 102, the filtering rule that filter element 103 is used for rule-based database 102 storages carries out filtration treatment to the content of this roamer's transmitting-receiving.
Rule change transmitting element 204 among the HCS200, in detecting rule database 203 storage this user is received and dispatched rule that content filters when changing, the filtering rule after changing is sent to VCS100 in the visited network of roamer place; The first Policy Updates unit 104 among the VCS100 is based on roamer's home network filtering rule after the user being received and dispatched the variation of sending when rule that content filters changes, the filtering rule that has got access to of storage in the update rule database 102.
Acquiring unit among the VCS100 101 also obtains the rule sign corresponding with this filtering rule when obtaining filtering rule in addition, and the filtering rule corresponding stored that the rule that will obtain identifies and obtains is in rule database 102.It is follow-up like this when VCS desires the filtering rule of storage in the update rule database 102, identify transmitting element 105 extracts the rule sign of storage and sends to the roamer in rule database 102 home network by rule, can when receiving the content that the interior perhaps roamer that sends to the roamer sends at every turn, follow-up VCS100 send the rule sign as rule sign transmitting element 105 to roamer's home network.Whether rule among HCS200 sign comparing unit 205 relatively identifies consistent to rule that should roamer's storage in the rule sign sent of the VCS100 in the visited network of roamer place and the rule database 203; Upgrade as a result feedback unit 206 when the comparative result of rule sign comparing unit 205 be unanimity, VCS100 feedback filtering rule in the visited network of roamer place is change notification not, and when comparative result is inconsistent, new filtering rule and corresponding new rule thereof are identified the VCS100 that sends in the visited network of roamer place.The rule sign that the second Policy Updates unit 106 among the VCS100 sends at rule sign transmitting element 105 according to roamer's home network and rule that should roamer's storage identified when inconsistent, the filtering rule of storage and corresponding rule sign thereof in new filtering rule of sending and the corresponding new regular identification renewal rule database 102 thereof.
