Embodiment
Below in conjunction with accompanying drawing, the present invention is done further detailed description.
The present invention is in the PHS network, the standard signaling of utilizing hot-zone notion and terminal when two paging zones carry out the physical location switching, to be triggered, a kind of message mode that triggers based on user terminal location is provided, promptly when the mobile subscriber enters these hot-zones, if there is a kind of device to detect soon, so just can be in time, send information to user very targetedly, the present invention is called the position broadcast service system with this system.Wherein the hot-zone is meant to spread news needs the area of covering, such as public places such as airport, square, school, buildings.Described message comprises short message, multimedia message and WAP link.
Figure 1 shows that, the network architecture schematic diagram of system of the present invention in the PHS network, this system comprises broadcast service system (LBS), position determining entity (GLC/LMSC), attaching position register (HLR), Short Message Service Gateway (SMG), mobile data services content supplier (CP/SP), switching center (IGW) and base station.LBS links to each other with position determining entity (GLC/LMSC), HLR, SMG and CP/SP respectively, and IGW links to each other with HLR and base station respectively, and the base station links to each other with user terminal by data link.Wherein be based on the interface of the manmachine command of Socket between HLR and the LBS system.
Carry out physical location when switching when terminal at two paging zones, IGW sends AlterPA message to HLR, carries the information of the new PA that the user enters in the message; The business operation support system BOSS of LBS by HLR obtains and the information of this new PA of temporary cache user; LBS is according to the information of this new PA, the user is realized zonal location positioning, LBS sends Location Request to position determining entity (location gateway GLC or centre of location LMSC) then, and position determining entity returns the longitude and latitude at the current place of user or the positional information of sector level to LBS after locating successfully; LBS judges by this positional information of returning whether the user is in the hot-zone, if the user is in the hot-zone, LBS follows the interface protocol of standard and transmits message by SMG to this user according to the different messages type.
The paging zone PA at the current place of HLR storage user accepts the user position update reporting information, and sends user's new PA information to position broadcast service system LBS; HLR reports interface that the information of Subscriber Number, the current PA of user is passed to the LBS system by user position update.
Position determining entity (location gateway GLC or centre of location LMSC) positions the user, locatees successfully and then returns the longitude and latitude at the current place of user or the positional information of sector level to LBS.Interface between position determining entity and the LBS both can have been followed the Ln interface specification and link to each other with location gateway GLC, also can follow the Le interface specification and link to each other with centre of location LMSC, and obtain the current position of user.
CP/SP is used for increasing or revising to the LBS request dynamic information of needs broadcasting.
SMG transmits message to user terminal.
LBS obtains user's new PA information by HLR, and information judges under user's the new PA whether have the hot-zone thus, if there is the hot-zone, this user may now or be about to appear in the hot-zone so, in case this user appears in the hot-zone, LBS should be able to be as soon as possible, find as much as possible, so that send the information that needs broadcasting to the user timely; LBS manages according to the different signatory PA of user, LBS supports a plurality of hot-zones, a plurality of signatory PA, and it is independently that the business of each signatory PA is carried out flow process, wherein signatory PA is meant in the PHS network, the scope that paging zone PA covers is bigger, and there is dozens of PA in a general city, and the hot-zone, such as building, square, its geographic range is much smaller, if having the hot-zone under a PA, this PA will be called signatory PA so.
Above-mentioned LBS receives the user profile of HLR, and LBS manages according to the PA at user ID and its place, and promptly LBS only collects the user of place, hot-zone PA.Obviously, because the PA zone is bigger, the hot-zone is less.Be in the user under the PA, some may be in the hot-zone, and some is in outside the hot-zone.Before concrete location, can't predict which user necessarily is in the hot-zone, therefore the process that issues of LBS location process and information all needs to take certain system resource, because the LBS business is a kind of business of auxiliary extended pattern, the system resource that takies is too much unsuitable, can not influence the carrying out of basic service of PHS network, therefore need LBS to increase flow control function.In addition, the user is a notice LBS system in switching the process of PA, and in this case, the probability of fringe region that the user is in PA is bigger.And common hot-zone more is the area that the user comparatively concentrates, and from the angle of the network planning, in order to guarantee the ICQ quality, the hot-zone is partial to the central area usually, the edge effect that the LBS system needs certain measure to alleviate this PA.
On the other hand, for the issue of non-public welfare information, the LBS of present embodiment also considers certain filtering policy, protects society's impression of user.Such as advertising message, if the user repeats in the short time to receive, can cause dislike psychology, thus the social image of impact position broadcasting.
In sum, LBS possesses following control strategy, in other embodiments, also can adopt one of following strategy or combination in any:
A, flow control strategy, LBS are wanted quantified controlling and are regulated the pressure that LBS takies the PHS resources of core network; It is too high to monitor the traffic carrying capacity transient pulse, and the business of automatic pause LBS is carried out.
B, user's window positioning time selection strategy, after the user entered place, hot-zone PA, the user not necessarily always was in outside the hot-zone, and the time (comprising resetting) that needs the choose reasonable location is to improve the probability that is caught in when the user is in the hot-zone.
C, scanning strategy, when the user of place, hot-zone PA more for a long time because the reason of flow control, all users can not all position, and therefore, need certain scanning strategy select suitable user priority to position.The optimisation criteria of scanning strategy is: improve the hot-zone information coverage, perhaps briefly, capture the hot-zone user as far as possible; Transmission information as much as possible.Described raising hot-zone information coverage is meant at certain hour in the cycle that hot-zone information is accurately thrown in to user's the sum and the ratio of the actual total number of users that occurred in the hot-zone.
D, privacy protection policy, user position information is a kind of privacy information for the user.When commencing business, the user's that needs protection privacy authority.LBS is the positional precision of limited subscriber on the one hand, and promptly LBS is in restriction Qos rank in the position requests of deciding the entity transmission, and the position of not exporting the user on the other hand is transparent to system operator.
E, user filtering strategy are used for the granting of control information, and whether protection user's impression is to transmitting time, number of times, the mode of information and send and control.
Figure 2 shows that the functional module structure schematic diagram of LBS in the system shown in Figure 1, LBS mainly comprises information management module, user's selection function, scanning input function, flow control function and position decision function on logic function, omitted information management module among the figure.
Information management module is used to obtain the information of user place paging zone, the information of storage paging zone and hot-zone information thereof and managerial demand broadcasting.
The Subscriber Queue administration module is used to manage the user profile of signatory PA, calculates user's location priority level, and the user priority that priority is high passes to the scanning of scanning input functional module.
User's location priority level is in order to find to have appeared at the user of hot-zone as far as possible soon, as much as possible, then information to be sent to the user.Calculating user's location priority level strategy has multiple, below provides 2 examples:
Strategy one: a thresholding time is set, and it is short more that the user enters the time difference of time of PA and this thresholding time, then the priority height.This tactful basic thought is: the user enters that time of PA is too short or long, and user's behavior is more unpredictable, and navigating to the user, to be in the possibility of hot-zone lower.
Strategy two: on the basis of strategy one, increase the calculating that in historical Location Request number of times, the distance parameters such as time of a last Location Request in user's estimated delay positioning time, the one-period or its combination position priority level, and every multiply by a factor coefficient.Wherein estimated delay positioning time is to come predictive user to enter the time of hot-zone according to the current position of user, center, hot-zone, PA center, can improve the possibility that discovery has appeared at the user of hot-zone thus.
The arrangement that an above-mentioned tactful preferred application is advanced priority in the user who newly enters PA.And tactful two preferred application are carried out priority arrangement again to the user under other situation.
The flow control function module is used to provide flow calculation model, the flow that the overall arrangement business is carried out, supervisory control system flow, automatic pause, recovery business etc.As when the user of signatory PA is too much, the paging pressure of signatory PA increases, and the flow control function module is suspended carrying out of LBS business, and when the paging pressure of PA reduced, it is professional that the flow control function module is recovered again.
The scanning input functional module is used for according to the user filtering constraints of setting the user being scanned, and gives position decision function module with the user's that satisfies condition number notifying.These filter constraints can be based on user filtering strategies such as privacy of user protection strategy, user's positioning strategies.
Comprise following user filtering constraint strategy in the present embodiment and filter constraints accordingly, but in other embodiments, also can comprise a kind of or combination in any in the following situation:
When (1) user has just entered PA and promptly has been in the edge of PA, also has certain distance apart from the hot-zone, need to postpone to locate behind the certain hour, can determine by time and current time that user relatively enters PA, greater than a designated time, then satisfy this filtration constraints as user's current time and the difference that enters the PA time;
(2) user continuously the time of location need certain interval, and the total degree of continuous location is limited, the time interval of adjacent twice location of promptly same user reaches time threshold, perhaps locatees total degree when not reaching thresholding, satisfies this filtration constraints;
(3) user is under the PA for a long time, and the number of times of perhaps attempting the location in the cycle reaches the total degree thresholding of setting, does not then satisfy this filtration constraints and tackle this user deactivating, and thinks that this user has left PA and do not notified LBS;
(4) it is controlled that the user receives the information total degree of broadcasting, when promptly the number of times of user's receiving broadcasting information does not reach thresholding, satisfies this filtration constraints;
(5) user is provided with the information screen function, and perhaps the user is in the hot-zone during permanent resident population, does not satisfy this filtration constraints, will no longer this user be sent the trial of broadcast message.The information screen function that the user is provided with is collected customer complaint information, is obtained when the user orders information belonging to a category by LBS.
Position decision function module is used for receiving behind the Subscriber Number of overscanning, according to constructing Location Request and send to position determining entity with the interface of position determining entity, after obtaining the current position of user, when being in the hot-zone as the user, then the information that will need to broadcast by gateway is delivered to the user.
Figure 3 shows that the business process map of Fig. 1 system, may further comprise the steps:
Step 301:LBS is provided with the information of paging zone, hot-zone information, managerial demand broadcasting, and outside CP sends the increase of request dynamic or revises the information that needs broadcasting to LBS;
Step 302:LBS sends response message to CP;
Step 303: when the mobile subscriber enters PA2 from paging zone PA1, initiate position updating process, IGW obtains user's reposition PA2, upgrades signaling, the information that carries user ID in the signaling and newly enter PA to the HLR reported position;
Step 304:HLR sends MML order, the information that has user ID in the order and newly enter PA according to configuration to LBS;
The information that step 305:LBS receives user ID and newly enters PA, if PA is non-signatory PA, the information, the user that then need to upgrade the user leave the information of former place PA, process ends; If signatory PA, LBS chooses suitable user by control strategy, positions, and sends Location Request to position determining entity (location gateway GLC or centre of location LMSC) then;
Step 306: position determining entity returns user's positioning result, and LBS judges whether user's geographical position is in the hot-zone, when the user is in the hot-zone, enters step 307, otherwise process ends;
The information that step 307:LBS will need to broadcast is forwarded to the terminal use by Service Gateway.
Described Service Gateway is according to the difference of information and difference, if the information of the hot-zone that sets in advance is note or multimedia message or WAP link etc., then LBS links to each other with the corresponding business gateway, thereby Service Gateway has been omitted in issuing of realization information among the figure.
In the above-mentioned steps, the LBS system specifically may further comprise the steps the process that a certain signatory PA chooses suitable user and subsequent treatment, as shown in Figure 4:
Step 401:LBS calculates user's location priority level (method is as indicated above), according to priority level the user under the same PA is arranged;
Step 402: judge whether PA has flow margin, if then enter step 403, otherwise, the end process flow process;
Step 403: choose the high user of priority;
Step 404: scanning user;
Step 405: judge whether the user satisfies the filtration constraints of all scannings, if, carry out step 406, if not satisfying any one, the user do not filter constraints, execution in step 411;
Step 406: the flow information that upgrades PA;
Step 407: the scanning input functional module sends to Subscriber Number the position decision function module of LBS;
Step 408: position decision function module is constructed Location Request for this user, to position determining entity request user's latest position, receives final positioning result;
Step 409: position decision function module judges according to reposition whether the user is in the hot-zone, if carry out step 410, otherwise advance to return step 401;
Step 410: position decision function module notification gateway sends the information that needs broadcasting, finishes this operating process then;
Step 411:LBS upgrades this user's information, judges whether again to deactivate to the user, if, LBS end process flow process (unless this user enters this PA again once more) then, otherwise change step 401 over to.
Related LBS can support a plurality of hot-zones, a plurality of signatory PA in the above-mentioned flow process.Each signatory PA manages current user's collection independently.Simultaneously, each PA dynamically upgrades the total number of users of PA, the information such as paging amount of PA, and statistics sends number of users, the customer location overall distribution state of broadcast message, the estimation coverage rate of hot-zone information etc.These parameters are further used for the user's of back the calculating and the arrangement of priority level again.LBS is in this dynamic operation, optimizing process, and the information coverage of hot-zone will increase, and systematic function is progressively optimized.
The above only is preferred embodiment of the present invention, and in order to restriction the present invention, within the spirit and principles in the present invention all, any modification of being done is not equal to replacement, improves etc., all should be included within protection scope of the present invention.

(a) position broadcasting is carried out the priority level arrangement to each user in having the same paging zone of hot-zone, and judges whether this paging zone has flow margin;
(b) if this paging zone has flow margin, position broadcasting scans the user according to priority order from high to low, judges whether the user satisfies the filtration constraints of scanning;
(c) if the user satisfies the filtration constraints of all scannings, the flow information of paging zone is upgraded in position broadcasting, for this user constructs Location Request, and send Location Request to position determining entity, position determining entity returns the final positioning result of this user and broadcasts to the position then;
(d) position broadcasting judges by the positioning result that returns whether this user is in the hot-zone, if the message that the position broadcast transmission need be broadcasted is to user terminal.
13, method as claimed in claim 12, it is characterized in that, described step (a) medium priority is entered the time difference of the thresholding time of time of paging zone and setting and judges by the user, short more then user's of described time difference priority is high more, and the judgement of this kind priority is applicable to that the user newly enters the situation of the paging zone that has the hot-zone.
14, method as claimed in claim 12, it is characterized in that, described step (a) medium priority is entered the time difference of the thresholding time of time of paging zone and setting by the user, in the time of user's estimated delay location, the one-period in the number of times of historical Location Request, the distance parameters such as time of a last Location Request one or its combination judge, this kind priority is judged and is applicable to that the user is not the situation that newly enters the paging zone that has the hot-zone.
15, method as claimed in claim 12 is characterized in that, filters constraints in the described step (b) and be following any or its combination in any:
(1) user's current time and the difference of time that enters paging zone then satisfy this filtration constraints greater than a designated time;
(2) time interval of adjacent twice location of same user reaches time threshold, and perhaps the user locatees total degree when not reaching thresholding, satisfies this filtration constraints;
(3) user is under the paging zone for a long time, and perhaps the number of times that the user attempts locating in the cycle reaches the total degree thresholding of setting, does not then satisfy this filtration constraints;
When (4) number of times of user's receiving broadcasting information does not reach thresholding, satisfy this filtration constraints;
(5) user is provided with the information screen function, and perhaps the user is in the hot-zone during permanent resident population, does not satisfy this filtration constraints.
16, a kind of position broadcast system is characterized in that, comprises information management module, Subscriber Queue administration module, scanning input functional module, flow control function module and position decision function module;
Information management module is used to obtain the information of user place paging zone, the information of storage paging zone and hot-zone information thereof and managerial demand broadcasting;
The Subscriber Queue administration module, the user profile that is used to manage signatory paging zone, calculating user's location priority level, the user priority that priority is high passes to the scanning of scanning input functional module;
The flow control function module is used to provide flow calculation model, the flow that the overall arrangement business is carried out, and the supervisory control system flow, when paging zone has flow margin, this module controls position broadcast system operate as normal;
The scanning input functional module is used to select qualified user, and this module determines to satisfy the user who filters constraints through scanning, and gives position decision function module with user's number notifying;
Position decision function module is used to receive through scanning and determines the Subscriber Number that satisfies condition, and to the current location that position determining entity is inquired about this user, then sends broadcast to this user as its current location in the hot-zone.
