Embodiment
Below in conjunction with the accompanying drawing in the present embodiment, the technical scheme in the present embodiment is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Before the present embodiment is described, first the network architecture of D2D technology is briefly introduced.
As shown in Figure 1, in incumbent operator network, merchant tenninal and user terminal dock with the advertisement pushing server in network respectively, in the time carrying out advertisement pushing, merchant tenninal reports ad content to advertisement pushing server, by advertisement pushing server, ad content is sent to each user terminal.This advertisement pushing mode based on Incumbent network all needs the forwarding of advertisement pushing server participation ad content in the time of each advertisement, therefore larger to taking of Internet resources.For example, if merchant tenninal need to push certain ad content to 10000 user terminals in certain region, need to report this ad content to carrier network, amount to the ad content of 10000 times to each user terminal respectively by carrier network and forward, to push mode very serious to taking of carrier network resource for existing ad content as can be seen here.
As shown in Figure 2, in D2D network, broadcast terminal is connected with the signaling plane that carrier network is set up as shown in phantom in Figure 2 respectively with receiving terminal, and the user's face that simultaneously also can set up between each terminal as shown in solid line in Fig. 2 connects.Carrier network is connected and all terminals is carried out to the controls such as D2D service access, transfer of data by signaling plane, and broadcast terminal can connect directly to receiving terminal broadcast transmission of data content by user's face under the control of carrier network.Due to can be directly to receiving terminal data content at D2D net environment broadcast terminal, if therefore D2D technology is applied in ad content propelling movement process, can save the forwarding operation of carrier network to ad content, can save in a large number thus the Internet resources of carrier network.
Concrete, push tying up in a large number carrier network resource for reducing ad content, a kind of method that the present embodiment provides ad content to push, the ad content that the method can utilize up-to-date D2D technology that broadcast terminal directly need to be pushed to receiving terminal broadcast transmission under the control of carrier network.As shown in Figure 3, the method comprises:
301,, in D2D network, network side carries out legitimate verification to broadcast terminal ad content to be pushed.
Regulation according to current 3GPP standard agreement to D2D technology, network side is connected the transfer of data behavior of broadcast terminal is controlled by signaling plane, and the control that broadcast terminal cannot depart from signaling plane connection realizes separately data content transmission.In the present embodiment, broadcast terminal connects directly to each receiving terminal broadcast transmission ad content by user's face, but for the ad content of broadcast terminal broadcast is verified, before advertisement content, network side connects the ad content to be pushed to broadcast terminal mandatory requirement by signaling plane.Under the control connecting at signaling plane, the ad content that broadcast terminal does not report network side cannot directly broadcast to receiving terminal.Concrete, before the each advertisement content of broadcast terminal, between network side and broadcast terminal, initiate to find (Discovery) flow process by existing 3GPP TR23.703 agreement, require broadcast terminal to report ad content to be pushed to network side.In practical application, a kind of flow process in 15 kinds of discovery flow processs that network side and broadcast terminal can be recorded according to 3GPPTR23.703 agreement the 6th chapter 6.1.1 to 6.1.15 realizes, and the present embodiment no longer repeats.
In practical application, network side can carry out artificial examination to ad content by network manager, also can such as, carry out automatic examination by technology such as semantic analyses to ad content according to proof rule (advertising theme, responsive vocabulary etc.) default and storage in advance by network equipment, the present embodiment not content to legitimate verification and concrete mode limits.
In the present embodiment, broadcast terminal is the merchant tenninal as advertisement pushing side, and receiving terminal is the user terminal as advertisement side, and the present embodiment is follow-up all replaces explanation with broadcast terminal and receiving terminal.It should be noted that, be only the division in function to the differentiation of broadcast terminal and receiving terminal, and in practical application, for terminal equipment itself, its function both with information broadcasting also has the function that receives broadcast data simultaneously.
If 302 ad contents are legal, network side is that ad content distributes content identification.
When ad content is by after legitimate verification, network side is that this ad content distributes a content identification, and content identification, for an ad content is carried out to unique identification, can be generated at random by system.The form of content identification includes but not limited to it is numeral or character string, and the present embodiment does not limit this.
303, network side, according to the area identification of the device identification of content identification, broadcast terminal and advertisement content, generates standard key.
Broadcast terminal is in the time reporting ad content, and network side obtains the device identification of broadcast terminal, and the target area pushing with broadcast terminal agreement ad content.Determining that behind target area, network side obtains the area identification of target area, thus, network side acquires content identification, the device identification of identification of broadcast terminal and the area identification of mark target area of mark ad content.Network side, according to default cryptographic algorithm, generates standard key according to content identification, device identification and area identification afterwards.Described cryptographic algorithm can be selected and adopt general algorithm in prior art, and the present embodiment does not limit specific algorithm.
304, network side is encrypted ad content according to standard key, and the ad content after encrypting is sent to broadcast terminal.
Concrete, distributing after content identification, content identification is sent to broadcast terminal by network side, and in the time carrying out advertisement pushing, broadcast terminal is take this content identification as foundation is to network side request ad content.Network side, receiving after the content identification that broadcast terminal reports, is searched corresponding ad content according to this content identification, and the standard key then generating according to step 303 is encrypted ad content, finally the ad content after encrypting is sent to broadcast terminal.
305, broadcast terminal generates temporary key according to content identification, device identification and area identification.
Broadcast terminal obtains the area identification of the current target area that needs advertisement to network side, in conjunction with the content identification of obtaining before this and the device identification of self, independently generate temporary key according to the cryptographic algorithm identical with network side cryptographic algorithm in local side again.
It should be noted that, the area identification in realistic objective region when broadcast terminal carries out advertisement pushing in this step is not necessarily identical with the area identification of the agreement in advance of both sides in step 303.For example, advertisement pushing is carried out in broadcast terminal and network side agreement in community 1, in actual propelling movement process, if broadcast terminal carries out advertisement pushing in community 1, the area identification in realistic objective region is 1, if broadcast terminal carries out advertisement pushing in community 2, the area identification in realistic objective region is 2.Generating when temporary key, broadcast terminal is take the area identification in realistic objective region as according to generating temporary key.
306, broadcast terminal is decrypted the ad content after encrypting according to temporary key, and by D2D technology, the ad content after deciphering is broadcast to receiving terminal.
Broadcast terminal is decrypted the ad content receiving in step 304 according to the temporary key generating in step 305.If temporary key is identical with the standard key that network side generates, broadcast terminal can successfully be deciphered ad content, if temporary key is not identical with the standard key that network side generates, the ad content after deciphering is mess code, and receiving terminal cannot correctly receive.
In the present embodiment, determine that the temporary key condition whether identical with standard key comprises:
1) device identification that when whether the device identification of the broadcast terminal of advertisement pushing is verified with ad content, network side obtains is identical;
2) content identification that when whether the content identification of ad content is verified with ad content when advertisement pushing, network side distributes is identical;
3) area identification of the target area of agreement is identical in advance with broadcast terminal and network side for area identification when advertisement pushing.
Only have above-mentioned three aspects: condition all corresponding when identical, broadcast terminal can generate correct temporary key, thereby successfully ad content is decrypted to transmission.In the present embodiment, because the generation of temporary key is subject to the restriction of device identification, therefore can avoid the broadcast terminal advertisement content privately without network side mandate.Secondly, because the generation of temporary key is also subject to the restriction of content identification, therefore when ad content is verified without network side, or while checking by network side, network side can not be this ad content distribution content identification, and then can avoid broadcast terminal privately to push the ad content of unauthenticated.In addition, because the generation of temporary key is also subject to the restriction of area identification, therefore when broadcast terminal is in agreement in other regions beyond region when advertisement, actual area mark makes the temporary key of broadcast terminal generation different with the standard key of network side generation from the different meetings of agreement area identification, and then can avoid broadcast terminal in unauthorized region, to carry out advertisement pushing.
In prior art, merchant tenninal relies on carrier network to carry out ad content propelling movement, just need to forward how many times ad content by carrier network to how many user terminal advertisement contents.As everyone knows, the feature that ad content pushes is that audient is wide general, can seriously tie up the Internet resources of operator to a large number of users terminal advertisement content.The method that the ad content that the present embodiment provides pushes, can utilize up-to-date D2D technology to realize the propelling movement of ad content.Because the transmission of ad content forwards without network side, therefore can not take the Internet resources of operator to how many receiving terminal advertisement contents.In addition, the method that the ad content that the present embodiment provides pushes, can force the ad content of broadcast terminal to carry out legitimate verification, encrypt by network side, the mode of broadcast terminal side deciphering guarantees that broadcast terminal can only authenticate the ad content passing through by network side and successfully be pushed to receiving terminal, and for the unsanctioned ad content of authentication, because merger terminal cannot correctly be deciphered, therefore receiving terminal can only receive mess code, guarantee thus the ad content that broadcast terminal can only authenticate by legitimacy to receiving terminal broadcast transmission, and then realization pushes effective supervision of behavior to merchant advertisements.
It should be noted that, although relate to the process that sends ad content and follow-up a series of data interactions to network side in the process of ad content checking, but after ad content is verified, broadcast terminal can be directly to receiving terminal broadcast transmission ad content, without the Internet resources that take operator.No matter broadcast terminal is to how many receiving terminal broadcast transmission ad contents, in verification process, all only send an ad content to network side, in verification process, data interaction is very little to taking compared with the carrier network resource of saving in advertisement pushing process of carrier network resource, negligible on the impact of the present embodiment technique effect.
Further, as the refinement to method shown in Fig. 3 and expansion, a kind of method that the present embodiment also provides ad content to push, the method comprises ad content checking and ad content pushes two flow process stages.First the flow process stage of ad content checking is described.
As shown in Figure 4, the flow process of ad content checking comprises:
401,, in D2D network, advertisement pushing server carries out D2D activation of service to broadcast terminal and receiving terminal.
Broadcast terminal and receiving terminal send D2D service request to advertisement pushing server respectively, advertisement pushing server receives D2D service request, and be that broadcast terminal is opened D2D data broadcast function according to the difference of class of business, for receiving terminal is opened D2D data receiver function.
402, advertisement pushing server receives the ad content that broadcast terminal sends.
In the present embodiment, be that example describes with Mobility Management Entity (Mobility Management Entity is called for short MME) as dynamic management equipment.Broadcast terminal sends ad content to be pushed by the MME in core net to advertisement pushing server, and ad content is sent to advertisement pushing server by MME, the device identification of broadcast terminal is together sent to advertisement pushing server simultaneously.
In the present embodiment, can use international mobile subscriber identity (International Mobile Subscriber Identification Number, be called for short IMSI) or International Mobile Station Equipment Identification (International Mobile Equipment Identity, be called for short IMEI) as the device identification of broadcast terminal, the present embodiment does not limit the concrete form of device identification.
403, ad content and device identification are sent to business platform by advertisement pushing server.
The ad content obtaining from MME and device identification are transmitted to business platform by advertisement pushing server.
404, business platform and broadcast terminal are determined the region that ad content wish pushes, and obtain area identification.
The target area of advertisement pushing determines according to the popularization demand of trade company by broadcast terminal, and business platform is being determined behind target area with broadcast terminal, searches the area identification that obtains this region in background data base.In the present embodiment, described area identification can be specifically cell ID, and the present embodiment does not limit this.
405, business platform carries out legitimate verification to ad content.
The ad content that business platform sends advertisement pushing server carries out legitimate verification.If ad content is by legitimate verification, business platform execution step 406, for this ad content distributes content identification; If ad content is not by legitimate verification, business platform abandons this ad content, sends a notification message, and finish checking flow process to broadcast terminal.
406, business platform is to distribute content identification by the ad content of legitimate verification.
The implementation of this step is identical with the implementation of step 302 in Fig. 3, repeats no more herein.
407, business platform generates standard key.
Business platform is according to the content identification distributing in the area identification finding in the device identification of obtaining in step 403, step 404 and step 406, for this ad content generates standard key.
408, content identification and standard key are sent to advertisement pushing server by business platform.
Content identification is sent to broadcast terminal by advertisement pushing server, so as when follow-up advertisement as the locking foundation of ad content.The ad content receiving in content identification, standard key and step 402 is sent to static management equipment by the server of advertisement pushing simultaneously.The data that static management equipment interconnection is received are preserved, so that follow-up mandate advertisement pushing is used.
In the present embodiment, describe as static management equipment with attaching position register (Home Location Register is called for short HLR), in practical application, static management equipment can also be local subscribed services device (Home Subscriber Server is called for short HSS).
In a preferred version of the present embodiment, for ease of the data that receive are managed and are searched, HLR is except preserving content identification, standard key and ad content, can also preserve the mapping relations between three, example, the mapping relations table that HLR preserves as shown in Figure 5.
So far, network side completes the flow process to ad content checking, enters next stage ad content is pushed.
As shown in Figure 6, the flow process that ad content pushes comprises:
601,, in D2D network, advertisement pushing server receives the content identification that broadcast terminal sends.
In the time carrying out ad content propelling movement, the content identification that broadcast terminal sends advertisement pushing server in above-mentioned steps 408 by MME sends to advertisement pushing server, to inform that advertisement pushing server broadcast terminal need to push the corresponding ad content of this content identification.
602, content identification is sent to static management equipment by advertisement pushing server.
HLR receives after this content identification, searches standard key and ad content that should content identification in the mapping relations table shown in Fig. 5, then standard key and ad content is read.
603, static management equipment is encrypted ad content according to standard key.
604, the ad content after encrypting is sent to advertisement pushing server by static management equipment.
The ad content after encrypting is sent to advertisement pushing server by HLR, is transmitted to broadcast terminal by advertisement pushing server.
605, broadcast terminal generates temporary key according to content identification, device identification and area identification.
The implementation of this step is identical with the implementation of step 305 in Fig. 3, repeats no more herein.
606, broadcast terminal is decrypted the ad content after encrypting according to temporary key, and by D2D technology, the ad content after deciphering is broadcast to receiving terminal.
If the temporary key that broadcast terminal generates is identical with the standard key that business platform generates, can successfully decipher ad content, the ad content that broadcast terminal is deciphered success by D2D technology broadcasts to each receiving terminal; If the temporary key that broadcast terminal generates is different from the standard key that business platform generates, the ad content after deciphering is mess code, and receiving terminal cannot receive this ad content.
In the present embodiment, the mode that network side mates by temporary key guarantees only to allow authorized broadcast terminal to send the ad content that process legitimacy is checked reach an agreement in advance and pass through in the target area of network side license.As long as push main body, push area and send the data that have a factor to obtain in advance from network side between object three corresponding different together, broadcast terminal just cannot be decrypted transmission to ad content, realizes thus the effective supervision of network side to broadcast terminal advertisement pushing behavior.
Further, consider that trade company can push same ad content by different broadcast terminals, or for same ad content, the situation that trade company can push in different target areas, because standard key and temporary key are according to device identification, content identification and area identification generate, therefore in the time that broadcast terminal changes (being that device identification changes) or the target area of advertisement pushing changes (being that area identification changes), the key that ad content is corresponding also can change, thereby an ad content (content identification in other words) tends to corresponding multiple key in actual applications.The flow process stage pushing at ad content, for finding more fast and accurately the standard key that ad content is corresponding, in another preferred version of the present embodiment, advertisement pushing server can also generate temporary key voluntarily, by this temporary key, static management equipment can be located fast to the standard key of ad content.
Concrete, as the replacement to implementation shown in Fig. 6, as shown in Figure 7, the flow process stage that ad content pushes comprises:
701, advertisement pushing server receives the content identification that broadcast terminal sends.
In the time carrying out ad content propelling movement, the content identification that broadcast terminal sends advertisement pushing server in above-mentioned steps 408 by MME sends to advertisement pushing server, to inform that advertisement pushing server broadcast terminal need to push the corresponding ad content of this content identification.
Advertisement pushing server in the time receiving the content identification that MME forwards, the device identification of also obtaining this broadcast terminal to MME, and broadcast terminal is wished the area identification of the target area of carrying out advertisement pushing.
702, advertisement pushing server generates temporary key according to the content identification receiving, device identification and area identification.
Different from implementation shown in Fig. 6, advertisement pushing server needs self to generate temporary key, and sends to HLR with the content identification in this temporary key replacement step 602.The implementation of this step is identical with the implementation that broadcast terminal in Fig. 3 step 305 generates temporary key, but it should be noted that, the object that both generate temporary key is not identical: in Fig. 3, the object that broadcast terminal generates temporary key is that the ad content of network side being encrypted according to temporary key is decrypted transmission; In this step, the object of advertisement pushing server temporary key is to make HLR in the cipher key list of preserving, to navigate to fast the standard key of corresponding ad content according to this temporary key.
703, the temporary key of generation is sent to static management equipment by advertisement pushing server.
As shown in Figure 8, preserve standard key according to " device identification-> content identification-> standard key " three DBMS tables HLR inside.As previously mentioned, same ad content can be pushed to different target area (i.e. corresponding different area identification), and therefore same ad content (being content identification) can corresponding multiple standard key.HLR is receiving after the temporary key of advertisement pushing server transmission, only need to travel through the standard key of storage according to this temporary key, compare successively temporary key whether identical with the standard key of storage, if comparison result is identical, the standard key identical with temporary key is defined as to the standard key of current ad content, order is carried out subsequent step; If the not standard key identical with temporary key, network side finishes advertisement pushing flow process, and sends a notification message to broadcast terminal.
704, static management equipment is encrypted ad content according to standard key.
705, the ad content after encrypting is sent to advertisement pushing server by static management equipment.
706, broadcast terminal generates temporary key according to content identification, device identification and area identification.
707, broadcast terminal is decrypted the ad content after encrypting according to temporary key, and by D2D technology, the ad content after deciphering is broadcast to receiving terminal.
Step 704 is identical to the implementation of step 606 with step 603 in Fig. 6 respectively to the implementation of step 707, repeats no more herein.
Further, for further shortening searching the time of standard key, in another preferred version of the present embodiment, advertisement pushing server can also send to content identification static management equipment, first according to the settle the standard traversal sample of key of content identification, and then in traversal sample, standard key is traveled through one by one to comparison according to temporary key by static management equipment.Reduce the traversal number of times of static management equipment by dwindling the mode of traversal sample space, and then shorten searching the time of standard key.Concrete:
Storage organization shown in Fig. 8 is converted, the standard key of storage is classified as classification dimension using content identification, obtain tables of data as shown in Figure 9.In Fig. 7 step 703, advertisement pushing server, except to HLR sends temporary key, also sends content identification to HLR.HLR, receiving after the data that advertisement pushing server sends, first according to the content identification cipher key list that settles the standard, narrows down to a standard key list by traversal sample from the overall standard key of preserving thus; Then HLR travels through comparison according to temporary key to the standard key in standard key list more one by one, can greatly save thus the traversal spent time of standard key.
The method that the ad content that the present embodiment provides pushes, except can be in the propelling movement main body of advertisement pushing, push target and push object supervises, the mode that can also generate temporary key by network side improves the efficiency of the standard key that static management equipment searches, and is more applicable for practical application.
Further, with reference to the realization of said method, the system that the present embodiment also provides a kind of ad content to push, in order to realize said method.As shown in figure 10, described system comprises: business platform server 1001, advertisement pushing server 1002, static management equipment 1003, broadcast terminal 1004 and receiving terminal 1005, and in order to said method is realized.Concrete:
