Description
Technical field
The present invention relates to wireless communication technology field, particularly method, equipment and the communication system of proximity relations between a kind of definite subscriber equipment.
Background technology
Third generation partner program (3rd Generation Partnership Project at present, two subscriber equipment (User Equipment of definition 3GPP), UE) communication process between, shown in Figure 1, the process that UE1 sends data to UE2 comprises:
Data are sent to the eNB1 into its service by UE1; ENB1 is receiving after data, and these data are delivered to gateway (Serving Gateway, SGW)/packet data gateway (Packet Data NetworkGateway, PDN GW); SGW/PGW, receiving after these data, according to the Route Distinguisher of UE1, routes the data to the SGW/PGW into UE1 service; Because UE1 in figure is identical with the SGW/PGW of UE2, for these data are delivered to the eNB2 into UE2 service by the SGW/PGW of UE2 service; These data are passed to UE2 by last eNB2, sends the process of data to complete UE1 to UE2; If the SGW/PGW of UE1 and UE2 service is not identical, the communication process between UE1 and UE2 also comprises that the PGW of UE1 routes data to the process of the PGW of UE2.
Can find out from said process, even if the position between two subscriber equipmenies of intercommunication is very near mutually, while transmitting data, also need by for eNB and the core net of service separately could arrive opposite end, make communication delay very large, but also can take more Internet resources.Therefore, 3GPP is studying about the communication technology between nearby device, that is: when the distance between two UE of needs communication is very near, realize direct transmission data between these two UE, its data transfer path is referring to shown in Fig. 2 A, between UE1 and UE2, can directly transmit data, and not need through any mobile network appliance; Or only realize the high-speed traffic between these two UE by the transmission of eNB, its data transfer path is referring to shown in Fig. 2 B, UE1 and UE2 are connected to same eNB, only realize and forward by this eNB the data that need transmission, forward and do not need to route data to core net.Above-mentioned two kinds of transmission meanss have greatly reduced the time delay of transfer of data, and can save Internet resources, especially save the Internet resources of core net.
At present, 3GPP SA1 is discussing the problem of implementation of adjacent communication, in order to realize the adjacent communication between UE, need to solve following two large problems: the proximity relations discovery procedure between the one, UE, the 2nd, determine between the UE of proximity relations how to realize direct communication.Wherein, the proximity relations discovery procedure between UE is not only the important prerequisite that realizes adjacent communication, can also support a lot of application scenarioss simultaneously.For example, businessman can, by detecting proximity relations, send and give a discount and promotional advertisement near the UE this businessman; And for example, the function that user can find by proximity relations, searches near the information such as restaurant and supermarket in its position; For another example, the function that bus stop can be found by proximity relations, the forecast public transport information of arriving at a station, etc.
In order to support machine type communication (Machine-Type Communication, MTC) characteristic of triggering (trigger), in the 3GPP network architecture, introduce new framework, shown in Figure 3, at public land mobile network (Public Land Mobile Network, PLMN) in network, increased an entity newly---machine type communication interactive function (Machine-Type Communication Interworking Function, MTC-IWF) entity, for being connected to each network element and the MTC server (server) of 3GPP network, and to MTC server shielding 3GPP topology of networks.Wherein, between MTC-IWF and Mobility Management Entity (Mobility Management Entity, MME), be provided with interface T5b, between MTC-IWF and home subscriber server (Home Subscriber Server, HSS), be provided with interface S6m.
UE uses internal indicator (internal ID) in 3GPP network, for example international mobile subscriber identifier (International Mobile Subscriber Identifier, IMSI) etc.; And the outside mark of mutual use (external ID) between UE and MTC server, outside mark and the mapping relations between internal indicator of each UE are kept at HSS.In the time that MTC server initiates to trigger (trigger) message to UE, what in trigger message, carry is the outside mark of UE; After receiving, go MTC-IWF HSS to inquire about the internal indicator that this UE is corresponding.HSS will return to the MME id information of the internal indicator that UE is corresponding and the UE preserving in HSS registration to MTC-IWF.MTC-IWF triggers corresponding message by T5b interface to MME after receiving information.
In sum, 3GPP has only defined the demand of finding for proximity relations at present, also not for the solution of carrying out proximity relations discovery between the subscriber equipment of mutual vicinity.

The application layer equipment of the embodiment of the present invention obtains and stores mapping relations and the positional information of CAMEL-Subscription-Information, internal indicator and the outside mark of each terminal; Find that in the proximity relations that receives first terminal after request, the proximity relations CAMEL-Subscription-Information corresponding according to described first terminal, determines that first terminal has the function that can find other-end; And judge whether the second terminal and first terminal meet proximity principle, and judged result is sent to first terminal, thus solve at present not for the problem of carrying out the solution of proximity relations discovery between the subscriber equipment of mutual vicinity.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
Shown in Figure 4, the method for proximity relations between a kind of definite subscriber equipment that the embodiment of the present invention provides, comprises the following steps:
Wherein, the CAMEL-Subscription-Information of each terminal and the internal indicator of this terminal are corresponding one by one
Wherein, this proximity relations finds to carry in request the outside mark of first terminal;
Wherein, the second terminal in the embodiment of the present invention refers to the terminal that is different from first terminal.
Judged result is sent to first terminal by step 44, application layer equipment, to complete proximity relations discovery procedure.
Wherein, the application layer equipment of the embodiment of the present invention can be (server) such as application servers.
In force, in step 42, application layer equipment determines according to following steps the CAMEL-Subscription-Information that first terminal is corresponding:
Application layer equipment is according to self internal indicator of storage and the mapping relations of outside mark, and definite proximity relations receiving finds that the outside of the first terminal carrying in request identifies corresponding internal indicator; And
Application layer equipment, according to the internal indicator of this first terminal, the CAMEL-Subscription-Information of the terminal of storing from self, is determined the CAMEL-Subscription-Information that this internal indicator is corresponding.
It should be noted that, for the terminal with proximity relations discovery feature, in its CAMEL-Subscription-Information, also comprise the proximity relations CAMEL-Subscription-Information of this terminal, the proximity relations CAMEL-Subscription-Information of terminal is: this terminal allows to find other-end and do not allow to be allowed to be found by other-end and do not allow to find that by other-end discovery, this terminal other-end, this terminal allow to find other-end and allow or not to be found by other-end and do not allow to find other-end by other-end discovery or this terminal; The proximity relations CAMEL-Subscription-Information of terminal is for all business relevant to proximity relations of this terminal, and any business relevant to proximity relations that this terminal activates all should be observed its signing proximity relations CAMEL-Subscription-Information.
In the invention process, a certain terminal does not have the function that can find other-end, comprising: this terminal does not have proximity relations discovery feature; Or this terminal has proximity relations discovery feature, but its proximity relations CAMEL-Subscription-Information allows to be found by other-end and do not allow to find other-end for this terminal; Or this terminal has proximity relations discovery feature, but its proximity relations CAMEL-Subscription-Information does not allow to be found by other-end and do not allow to find other-end for this terminal;
A certain terminal has the function that can find other-end, comprising: the proximity relations CAMEL-Subscription-Information of this terminal is found by other-end for this terminal allows to find other-end and permission; Or the proximity relations CAMEL-Subscription-Information of this terminal allows find other-end and do not allow to be found by other-end for this terminal.
In force, if first terminal does not have the function that can find other-end, application layer equipment is found after request in the proximity relations that receives this first terminal transmission, do not carry out proximity relations discovery procedure, or notify described first terminal not there is the function that can find other-end by application layer messages.
In the embodiment of the present invention, the proximity principle in step 43 refers to that distance between first terminal and the second terminal meets and imposes a condition.
Further, satisfied the imposing a condition of the distance between first terminal and the second terminal comprises following three kinds of modes:
Distance between first kind of way, first terminal and the second terminal is not more than the threshold value of setting;
Wherein, the threshold value of setting is empirical value, can set as required; For example, the distance between first terminal and the second terminal is not more than 500 meters etc.;
The second way, first terminal and the second terminal reside in same community; That is: first terminal is identical with the ID of the second current persistent district of terminal;
The third mode, first terminal and the second terminal reside in same base station; That is: first terminal is identical with the ID of the second current resident base station of terminal.
Owing to also having defined a kind of restriction scene to proximity relations discovery procedure in 3GPP, i.e. whether the discovery procedure of regulation proximity relations need to be registered relation in application layer with the proximity relations CAMEL-Subscription-Information of this UE, network configuration and two subscriber equipmenies is (the being social networks) factor analysis such as friends.
Illustrate: suppose that A, B and C use same social networks application, and A, B and C use the UE with contiguous business function, in the context that this social networks application layer is safeguarded, show below relation information: A and C is friend, C and B are friends, A and B are not friends, under this scene, need the contiguous discovery feature of realization as follows:
The UE of-A can find that C is at close position;
The UE of-C can find that A is at close position;
The social networks application of-A can know that whether C is at its close position;
The social networks application of-C can know that whether A is at its close position;
The UE of-B can not find that the UE of A is at its close position;
The social networks application of-A can not detect that whether B is at its close position;
The social networks application of-B can not detect that whether A is at its close position;
Therefore, proximity relations discovery procedure requires only to have between the UE of friends and could mutually find, if application layer shows between this UE it is not friends, can not mutually find, two contiguous terminals need to meet certain social networks, could mutually find.
For the restriction scene to proximity relations discovery procedure of above-mentioned 3GPP definition, further, in step 43, application layer equipment, in the time judging whether described the second terminal and described first terminal meet described proximity principle, also comprises:
Judge whether the second terminal and first terminal meet the social networks of setting.
In the embodiment of the present invention, the social networks of setting refers to that the personal status relationship between each terminal of same social networks registration meets and imposes a condition, wherein, the personal status relationship of inquiry between each terminal of same social networks registration in the context that application layer equipment can be stored at self, if UE1 and UE2 are friends, UE1 and UE3 are not friends etc.; And for example, UE1 and UE2 belong to same group, and UE2 and UE3 do not belong to same group; Etc.;
The social networks of setting can be friends for the second terminal and first terminal to be determined, or the second terminal to be determined and first terminal belong to the group of same setting, etc.; In the embodiment of the present invention, can be set according to actual needs the personal status relationship of each terminal of same social networks registration carrying out needing satisfied condition in discovery procedure.
Further, in the embodiment of the present invention, in step 41, application layer equipment obtains the positional information of this terminal by the mode of each terminal to report, concrete, and application layer equipment obtains the positional information of each terminal according to following steps:
Set up after PDN for transmitting application layer traffic aided is connected at terminal and Access Network, between application layer equipment and each terminal, set up application layer and be connected; And
Application layer equipment receives self current positional information the storage of each terminal to report, and positional information comprises: a kind of or combination in the ID of the current resident base station of ID, terminal of the current resident community of terminal, the geographical location information of terminal.
In force, terminal can be obtained by eating dishes without rice or wine the ID of self current resident community;
Terminal can, by self-contained GPS module, be obtained the GPS positional information of self, as latitude and longitude information.
Take the network architecture diagram shown in Fig. 5 as example, in this network architecture, in the middle of definition, between interactive device and HSS, undertaken alternately by interface Xy, this interface Xy is in order to realize CAMEL-Subscription-Information query script, and middle interactive device feeds back the CAMEL-Subscription-Information of each terminal and the internal indicator of each terminal and the outside mapping relations that identify to HSS transmission inquiry request and HSS to middle interactive device; In the middle of definition, between interactive device and application layer equipment, undertaken alternately by interface Xz, this interface Xy sends the mapping relations of the CAMEL-Subscription-Information of each terminal and the internal indicator of each terminal and outside mark to application layer equipment to the middle interactive device initiation CAMEL-Subscription-Information request of obtaining and middle interactive device in order to realize application layer equipment; It should be noted that, interface Xy and interface Xz can adopt existing any protocol stack to define, as long as can realize above-mentioned functions.
In this network architecture, the reciprocal process between terminal and application layer equipment is shown in Figure 6; Concrete, between UE1 and UE2 and application layer equipment, set up PDN and be connected, and report current location information separately to application layer equipment alternately by application layer; Accordingly, application layer equipment is in the positional information the storage that receive UE1 and UE2 and report, and while changing in the position of UE1 and UE2, the positional information of self storage of upgrading in time.
It should be noted that, each terminal is being attached to after network, to Access Network initiation packet data network (PacketData Network, PDN) connect and set up, and by packet data gateway (Packet Data NetworkGateway, PGW) SGi interface is set up PDN with Access Network and is connected, and detailed process refers to 3GPPTS23.401 agreement;
After setting up PDN connection, each terminal is set up application layer with application layer equipment respectively and is connected;
Each terminal reports self current positional information to application layer equipment;
Preferably, each terminal reports self current positional information to application layer equipment in real time; Or each terminal is after self current positional information changes, and reports self current positional information, the positional information of each terminal so that application layer equipment upgrades in time to application layer equipment.
Further, in the embodiment of the present invention, in step 41, application layer equipment obtains the CAMEL-Subscription-Information of this terminal from HSS by middle interactive device according to the outside mark of each terminal (as application layer mark), concrete, application layer equipment obtains the CAMEL-Subscription-Information of each terminal according to following steps:
Application layer equipment is initiated CAMEL-Subscription-Information to middle interactive device and is obtained request, and CAMEL-Subscription-Information obtains the outside mark of carried terminal in request;
Middle interactive device obtains after request receiving this CAMEL-Subscription-Information, sends inquiry request to HSS, to obtain the CAMEL-Subscription-Information of terminal, and the outside of carried terminal mark in inquiry request;
HSS is receiving after this inquiry request, mapping relations according to internal indicator with outside mark, determine that the outside that this inquiry request is carried identifies corresponding internal indicator, and interactive device in the middle of the internal indicator of CAMEL-Subscription-Information corresponding definite internal indicator and this terminal and the mapping relations of outside mark are sent to, wherein, there is the proximity relations CAMEL-Subscription-Information that at least comprises this terminal in the CAMEL-Subscription-Information of terminal of proximity relations discovery feature; And
The CAMEL-Subscription-Information of this terminal that middle interactive device returns to HSS and the internal indicator of this terminal send to application layer equipment with storage with the mapping relations of outside mark.
Still take the network architecture shown in Fig. 5 as example, in this network architecture, middle interactive device and application layer equipment, and reciprocal process between middle interactive device and HSS is shown in Figure 6.
It should be noted that, in HSS, preserve the CAMEL-Subscription-Information of each terminal, for the terminal with proximity relations discovery feature, in its CAMEL-Subscription-Information, also comprise the proximity relations CAMEL-Subscription-Information of this terminal, mutual owing to using outside mark to carry out between terminal and application layer equipment, and and between 3GPP network equipment, use internal indicator to carry out alternately, therefore, in HSS, also preserve the internal indicator of each terminal and the mapping relations of outside mark; General, the internal indicator of terminal is IMSI, and the outside of terminal is designated application layer ID(as terminal No. QQ, MSN account etc.).
Preferably, the middle interactive device of the embodiment of the present invention can be disposed separately, also can close and establish with MTC-IWF, can also close and establish with HSS.
Concrete, if closing, middle interactive device and MTC-IWF establish, middle interactive device can carry out alternately with HSS and application layer equipment respectively by interface Xy and interface Xz; Also can carry out alternately with HSS and application layer equipment respectively by the interface S6m of MTC-IWF and interface Tsp, wherein, defining interface S6m and interface Tsp have the function of above-mentioned interface Xy and interface Xz;
If middle interactive device and HSS close establish, middle interactive device carries out alternately with HSS and application layer equipment respectively by interface Xy and interface Xz, wherein, and the mutual employing interior signaling between middle interactive device and HSS.
Further, the proximity relations that first terminal is initiated finds that request comprises following two kinds:
The first proximity relations finds that request is: first terminal request determines whether this first terminal and the second terminal of self appointment meet the proximity principle social networks of proximity principle and setting (or meet); Wherein, proximity relations finds that request also carries the outside mark of the second terminal;
Under this application scenarios, first terminal needs to get the outside mark of second terminal of self specifying, as first terminal can obtain by application layer equipment the outside mark of the second terminal, can certainly adopt other modes to get the outside mark of the second terminal.
The second proximity relations finds that request is: first terminal request is determined and all the second terminals that self meet proximity principle (or social networks of proximity principle and setting).
For the restriction scene to proximity relations discovery procedure of above-mentioned 3GPP definition, initiate proximity relations at first terminal and find that after request,, in step 43, the proximity relations deterministic process that application layer equipment carries out describes below.
Find request for the first proximity relations, in step 43, further comprise:
