The location criteria that embodiment provides a kind of use to be used for the potential target user is filtered the information that is sent by broadcasting and multicast service, makes reception information and the user's who needs reception information significantly increase and do not reduce the method for this type of user's number of ratio.As long as play a role in the process of determining targeted group in the position, but with regard to using said method and equipment.
Distinct between the information that receives by portable terminal and the information by the mobile terminal user reception.Usually, filtration has increased actual number received information, that receive the mobile terminal user of information that uses.This can partially or completely realize by the ratio that increases the portable terminal that can represent the user that can use received information to use received information.Portable terminal may play a part less or inoperative in supporting the process of further filtering, and in the process of further filtering, the granularity that sets the goal is accurate.Arrival can use the portable terminal of received information also can finish by increasing the ratio of representing the user that can use received information to receive the portable terminal of information, in the case, portable terminal may play bigger effect in supporting the process of further filtering.Some examples of this embodiment further are provided herein.
In one embodiment, disclose the filter of a kind of position-based information and position relevant criterion.Allow broadcast transmission person to define ad-hoc location standard that the re-set target portable terminal satisfied so that it can receiving broadcasting information or broadcast message is delivered to the user, perhaps receive or transmit and have the information that particular priority is indicated.Described standard can be included among the various embodiment, but is not limited to following:
(a) as current location by the inner or outside destination mobile terminal in the geographic area of some appointments of different two-dimentional geometrical shape (for example, circular, ellipse or polygon) regulation.Add by the coordinate (for example, latitude, longitude) of stipulating some points and its geometric attribute and dimension can define each shape.For instance, border circular areas can be added its radius and be stipulated by the coordinate at its center.Polygon can use the coordinate on its each summit to be stipulated.
(b) destination mobile terminal is higher or lower than ground or is higher or lower than the current height on plane partly.Height gage can be decided to be a scope, destination mobile terminal need be in described scope or outside the described scope.
(c) destination mobile terminal as at (a) and/or (b) at certain specific previous time or during a previous time scope or the previous position that defines of any time in the past.
(d) destination mobile terminal as at (a) and/or (b) in certain specific following time or the following position during a following time range or in any time in future, defined.Following position may be based on the current mobile deduction to portable terminal, perhaps in some instances, based on mobile terminal user the following time in certain position or near or outside certain position or away from the known intention or the requirement of described position.For instance, the user may enter the destination address in the routing function of portable terminal.
(e) as at (a) and (b) above, (c) and/or the position of the portable terminal (d), but its mode with the town explains-for example, use the title in scope, street or one group of street of specific address, address, title and/or address, city/county/circle, state or well-known position (for example, airport, shopping center, gymnasium, theater, the hotel) of building.Under the situation of height, can use the basement height under ground or the bottom.
(f) be expressed as the present speed of the destination mobile terminal of a scope, destination mobile terminal is just advanced to be suitable for described standard in described scope or outside the described scope.
(g) be expressed as the current orientation (moving direction) of the destination mobile terminal of a scope, portable terminal is just advanced to be suitable for described standard in described scope or outside the described scope.
(h) past of moving of destination mobile terminal and/or following speed and past and/or following direction.
Can use any logical combination of above-mentioned standard, provide filtration than fine level by using logical, logical "or" and logic "No" operation group to close to state in the standard two or more.For instance, may make about primary highway in a direction but not the information of the obstruction on the other direction and the portable terminal (for example, may just consider to enter the user of highway) that just moving at closely adjacent obstruction place of identification add (logical "or") current location, speed and orientation hint may be associated blocking the location criteria that arrives the portable terminal of obstruction before may being eliminated.In another example, hurricane warning may be sent to the destination mobile terminal in a certain high constructure, the height that described high constructure exceeds a certain ground level is in the bigger danger it, therefore it is given notice.In a further example, may with send to when finding about the information of finding to lose article (for example, wrist-watch, jewelry, money) at the mall or the previous position before and after the discovery time make its in described shopping center or near destination mobile terminal.
Can be with above-mentioned standard and some non-geographic criteria combinations, described non-geographic criteria for example broadcast character (for example, the individual, that work is relevant, the public's or emergency), information (for example becomes important time, the date of selling event will take place) and sender's classification (for example, user's wireless carriers, friend/relative, employer, public safety personnel).Any filter operation is followed all available standards capable of being combined and (is for example determined validity, priority to the user), information with the pattern that is presented (for example, whether use the sense of hearing, vision and/or haptic signal) and possible information with time of being presented (for example, whether immediately, in certain time after a while through defining, perhaps only make certain request after a while when recognizing fresh information as the user).
In various embodiments, filter operation itself can be carried out by network and/or by user's wireless terminal and/or by the user.Can regard user's manual filtration as rely at last method, should avoid as much as possible because under the situation that the user stops with abolishment message, may produce delay and mistake and interference user.Under the situation of network filtering, network (for example, wireless network mobile switching centre (MSC), Serving GPRS Support Node (SGSN), call server controlled function (CSCF), base station sub-system (BSS), radio network controller (RNC)) can be by determining portable terminal the position or obtain about the current location of re-set target portable terminal by inquiry another entity (for example, position determination entity (PDE) or Serving Mobile Location Center (SMLC) or subscriber equipment (UE) itself), highly, the information in speed and orientation.Spendable localization method comprises this type of existing ability, as, enhancement type district identification (ID), uplink time-difference of arrival (U-TDOA), enhancement mode observed time difference (E-OTD), observation arrive time difference (OTDOA), auxiliary type global positioning system (A-GPS) and/or GPS.Also can use for example following navigation system such as Galileo in certain embodiments.
In addition, communication network can be retrieved and before obtain with the stored historical positional information or inquire that some servers are to obtain this information.Network also can be based on current location, speed and the orientation of (for example) portable terminal and is attempted inferring or otherwise predict the scope of the following position or the possible following position of portable terminal.Based on this positional information and the location criteria that is associated with broadcasting, network can be determined and should or specific broadcast message should do not sent to portable terminal.
Perhaps, position-based information and location criteria, whether and when network can determine and broadcast message should be sent to portable terminal, but have indication other some priority of significance level or indication with auxiliary described portable terminal decision access information.Priority or similar indication can be determined with the matching degree of the location criteria that is associated by the importance of broadcast message itself and the positional information of portable terminal.The priority indication then can be enabled the proper method of the availability of warning mobile terminal subscriber information.For instance, answer the urgent especially information of immediate access for the user, portable terminal can be warned described user by the sense of hearing, vision and/or sense of touch (for example, vibration) clue immediately based on the priority of height indication.Priority can change the indication user into should be very fast but needn't immediate access more not urgent but still information that may be important.In the case, portable terminal may only provide low-level audible indication (for example, some bleeps) and/or visual cues (for example, screen-icon).
In another embodiment, can be based on rough filter criteria with information broadcast or be multicasted to one group of portable terminal, described rough filter criteria is the service in the particular cell sectors of the membership qualification of multicast group and/or wireless network for example.Described information can be attended by the location criteria that is associated.Portable terminal will be for example by using as A-GPS, GPS, E-OTD, advanced forward link triangle are located a certain combination of this type of existing localization method such as (A-FLT), OTDOA, cell sector ID, enhancement type district ID or these methods, perhaps in future, by using the method for the novel global position system may utilize for example European GALILEO system, obtain the current location information of described portable terminal.Portable terminal also can read or by historical, retrieve previous position information and predict following positional information by the position before being next to.For instance, most of mornings, in work is travelled frequently, can take same paths, make second day, portable terminal is measurable be similar to that another work of before having travelled frequently is travelled frequently or can position change begin to duplicate before travelled frequently in during the content of observation described another work of prediction travel frequently.
Described terminal compares the location criteria of positional information and broadcast message and determine whether and information should be presented to the user, and if having what priority so.In case described terminal has determined whether and should present or the existence of warning message and may obtain particular priority to the user, described terminal just can have been done this as network and determines and obtain any priority information process information-for example, and it can be warned any urgent especially information of user immediately or more not urgent, the alarm that may postpone than low priority information can be provided.Tabular has gone out the exemplary customized alarm of various types of other location-based message.The user can with the screen interaction of application program or web screen or wireless terminal so that alarm is configured.In some cases, alarm can be relayed to other device (for example, TV or computer) among the personal area network to increase the possibility that the user discovers alarm by terminal.
Positional information in the information that portable terminal is broadcasted based on being included in and location information of terminals are carried out under the situation of filtering, and might determine whether and should before receiving all information information be provided to the user.Information is not presented to portable terminal if determine, so described terminal might be interrupted the reception of broadcast message, save terminal resource (for example, battery, processor, memory) whereby potentially and be used for receiving broadcasting information (it may unnecessarily use reverse link resources) and/or discharge terminal resource to be used for the opportunity cost of other task.
Also might in network and terminal, use filtration-for example, based on be present in the indicated approximate location information of terminal in specific cell and the cell sector in the rough filtration of network neutralization away from portable terminal, and the meticulousr more comprehensive filtration in the terminal.Also can use two filtered models support self can not to support the terminal of filtering subclass-under described situation, network may be carried out these subclass of terminal and filter, other terminal that can carry out filtration itself is finished this operation.
In some cases, communication network may know little about it or know nothing for the position and/or the identification code of expection wireless terminal.For instance, do not know or unreliable when knowing WLAN or WLAN position when wireless network, the user that its terminal is just inserting WLAN may know nothing the position.When potential recipient's portable terminal (is for example taken action passively, when not needing wireless terminal support call or other user's correlated activation) and can not be to network when himself being identified as the potential recipient of specific broadcasting, any wireless technology all may be known nothing identification code and position.In order to reduce the signaling overhead, if perhaps the broadcast/multi broadcast solution can not be discerned some or all of recipient users, so such situation may take place.Under this type of situation, network may need information broadcast to than the much bigger one group of portable terminal of set recipient and rely on location filtering in the portable terminal suitably to receive information and it is delivered to the user.
In another embodiment, network or portable terminal active bank or other method are with geographical location information (for example, lat/lon) is converted to town form (for example, street address, building identification) and this and any town relevant position standard compared.Network or portable terminal also can use the positional information and the standard of two types of town and geography (for example, lat/lon).For instance, in order to determine whether the portable terminal that is just moving may arrive described obstruction before the obstruction on the primary highway might be eliminated, have and necessary determine that by continuous location, geographical position portable terminal in fact just advances along highway, the geographical position navigate to the town form conversion or with town mapping information relatively confirmed position along highway.Other town mapping can comprise identification rural area/state/county/urban border.According to the position of portable terminal with respect to civic boundary, message can realize on portable terminal.
Hereinafter list some illustrative application:
