Please in conjunction with referring to Fig. 7, the method for subscribing of an embodiment location dependent information, also can implement based on the ordering system of above-mentioned location dependent information, present embodiment is by carrying the relative position condition in subscribe request, realized a kind of method for subscribing of position-based information, this method comprises the steps:
Step 702, the subscriber sends subscribe request to Subscriber, comprises the subscription condition of position-based relevant information in the subscribe request.The subscription condition is the relative position condition in the present embodiment, this relative position condition is that Subscriber sends the trigger condition of notifying to the subscriber, promptly by this relative conditon, the subscriber can only send notice by the given subscription server when satisfying relative conditon, and this relative conditon is based on the positional information of reference object and target, as, target enters or leaves the border at a distance of the reference object specific distance range, target within the certain scope of distance reference object or outside, target and reference object in identical or different zone (as the city, the section, street etc.), target and reference object be simultaneously in the specific region, the relative velocity of target and reference object etc.Certainly the relative conditon of position-based information is not limited thereto.
In other embodiments, relative conditon also can comprise the positional information of reference object, and, also can adopt the mode in external reference path to provide the positional information of reference object, this external reference path point reference object positional information provides the place, and Subscriber can be according to quoting the positional information that the path obtains reference object.
Subscriber and positional information server can be can provide to subscribe to and the server of positional information, as location server etc.
Can being accomplished in several ways alternately of subscriber and Subscriber is as SIP (SessionInitiation Protocol, session initiation protocol) subscribing notification, MLP (Mobile Location Protocol, running fix agreement) mode or the like.
Reference object can also be other entities of subscriber's appointment except subscriber self, and it also can be a plurality of that target both can be one.
Step 704, the relative conditon in the Subscriber storage subscribe request.
Step 706, Subscriber are obtained the reference object location dependent information.After Subscriber receives subscribe request, resolve the relative conditon in the subscribe request, and obtaining the positional information of reference object to positional information server according to wherein external reference path, Subscriber also can only be subscribed to the positional information relevant with the subscription condition of reference object.
The positional information server general reference external reference path server that the reference object positional information can be provided pointed is as presence server etc.Certainly, step 704 and step 706 be order in no particular order, repeats no more.
Step 708, positional information server are returned the location dependent information of reference object and are given Subscriber.If Subscriber and positional information server are integrated in the same device, then also can carry the reference object positional information in the relative conditon in the step 702 and quote the path, this device can provide reference object and target position information.
Step 710, Subscriber are obtained the positional information of target, and judge whether the target location satisfies relative conditon.Subscriber can obtain the positional information of target in several ways, when Subscriber is positioned at the target home domain, Subscriber can directly obtain the positional information of target, or target is positioned, or Subscriber obtains the positional information of target to other information sources.
Subscriber is according to the positional information of reference object and target, judge whether the target position satisfies relative conditon, if satisfy, execution in step 712, otherwise, handle accordingly according to ad hoc rules, as the position that continues tracking target etc., this ad hoc rules can be set for the subscriber, also may be the strategy of Subscriber self.
Whether the relevant information of judging target satisfies the subscription condition, also can be judge target with respect to the distance of reference object whether less than threshold value or greater than threshold value.The relevant information of judging target whether satisfy the subscription condition for the relative velocity of judging target and reference object whether greater than threshold value or less than threshold value or equal threshold value.
Step 712, Subscriber send and notify the terminal to the subscriber when satisfying relative conditon.
Except that above-mentioned situation, also there are some processing in other embodiments, comprise: if the relative conditon in subscriber's the subscribe request does not comprise the reference object positional information, but subscribe request comprises that (the geolocation header field is the SIP header field of an expansion for geolocation header field or functionally similar with it header field, be used for transmitting positional information in the SIP inter-entity, function comprises the route of positional information transmission end to end and acting server position-based information), then Subscriber can be automatically with the positional information of the information in this header field as reference object; If the relative conditon in subscriber's the subscribe request does not comprise the reference object positional information, and subscribe request does not comprise geolocation header field or functionally similar with it header field yet, then Subscriber can be located reference object by other modes, as: if Subscriber itself has the positional information of reference object, then can directly search and obtain in inside, otherwise, Subscriber can also obtain to relevant position information source according to the identify label such as the SIP URI of reference object, as location server, presence server etc., in addition, technology such as WiFi also can realize the location of server to client, certainly, the server method of initiatively obtaining the positional information of client is not limited thereto.
Please in conjunction with referring to Fig. 8, but subscriber's request server, at target and reference object in identical zone or different notify the subscriber when regional.This zone is specified by the subscriber, as: section, city, street or the like.Present embodiment is the instantiation of such relative conditon: A is a company clerk, he goes on business to Beijing, and run each big section transacting business every day in Beijing, in order to gather with near colleague local and own, he has and he colleague in same section as if among the colleague of Beijing branch by request server, then notifies.The SIP URI that supposes the colleague of A and Beijing branch is respectively user@example.com, workmate1@example.com, workmate2@example.com etc.This subscribing position-related information method comprises:
Step 802, A sends subscribe request to Subscriber, comprises relative conditon in this subscribe request, but does not comprise the positional information of A self.In the present embodiment, A subscribes to the colleague's of Beijing branch positional information to Subscriber, and by relative conditon given subscription server when monitoring with the colleague of A in same section, send notice.In the present embodiment client and server can adopt the MLP agreement alternately, subscribe request can followingly be represented:

Wherein, in the message body＜tlrr〉element representation trigger position report request, its daughter element＜msids〉and＜tlrr_event〉represent target and position informing trigger event respectively,＜msids〉daughter element＜msid the expression target identify label,＜rel_filter_same〉element representation notification triggers condition is in identical zone, present embodiment is in identical section.
On the contrary, also can be by in relative conditon, carrying＜rel_filter_different〉element, expression if target and subscriber in different zones, then server sends and notifies to the subscriber, as: if good friend and oneself is not or not a city, then server sends notice, allows oneself know that the good friend is current and roam, and has been unlikely to chat in number to know just that for a long time what oneself engage is toll telephone.
Step 804 after Subscriber receives subscribe request, is obtained the positional information of A to positional information server.In the present embodiment, the positional information that does not have A in the subscribe request, therefore Subscriber is attempted initiatively obtaining to positional information server, be specially, obtain the positional information of A to positional information server according to subscriber's identity information (SIP URI), as: if positional information server is location server or presence server, Subscriber can be subscribed to the positional information of A by SIP SUBSCRIBE method.
Step 806, positional information server are returned to Subscriber and are subscribed to failure response message.In the present embodiment, positional information server returns to Subscriber failure response message, and possible reason comprises that authentication is unsuccessful, the information deficiency that Subscriber provides etc.
Step 808, Subscriber returns failure response message to A, because Subscriber can't be known the positional information of A, prompting A resends subscribe request, and the positional information of self is provided.
Step 810, A initiates subscribe request again, comprises self-position information in this subscribe request, and having replenished the relative conditon after the positional information can be described below:
<tlrr_event>
<rel_filter_same>cl:civilAddress/cl:A4</rel_flter_same>
<rel_filter_locationURI>sip:sra14sdf@example.com</rel_filter_locationURI>
</tlrr_event>
Wherein,＜and rel_filter_locationURI〉the positional information place place of element representation A.
Step 812, Subscriber are subscribed to the positional information of A according to the external reference path in subscriber's the subscribe request to positional information server.
Since the subscriber wish to know target whether with own in same section, therefore Subscriber only needs with the current section of subscriber as basis for estimation, need not know the positional information that it is detailed, therefore Subscriber needs to subscribe to positional information server the section at subscriber place, can realize by in this subscribe request, carrying the notification filter condition, and positional information server is just notified Subscriber when only changing in the section at subscriber place.If positional information server is a presence server, and filter employing xml format identification (FID), then this filter can be following form:
<？xml?version＝″1.0″encoding＝″UTF-8″？>
<filter-set?xmlns＝″urn:ietf:params:xml:ns:simple-filter″>

Step 814, positional information server are returned the location information notification of A to Subscriber.
Step 816, Subscriber are obtained colleague's information according to the section at A place, and have judged whether that colleague of Pekinese and A are in same section.
Step 818 if colleague and A are arranged in same section, sends and is notified to A.
Please in conjunction with referring to Fig. 9, similar to the above embodiments, present embodiment also is based on reference object and target in identical or different zone, different is, the zone in the foregoing description relative conditon is an area type, as: city, street etc., and the predefined particular location that is the subscriber of the zone in the present embodiment, as: secretary A wish when she with some employee during just simultaneously in office, server sends and is notified to her, so that open a temporary meeting.This position-based relevant information method for subscribing comprises:
Step 902, secretary A sends subscribe request to Subscriber, and points out some employee and A while in the relative conditon that carries when office, server notification secretary A.The SIP URI that supposes secretary A and employee is respectively: user@example.com, and employee1@example.com ... (employee may be many people).If adopt Session Initiation Protocol, then subscribe message is as follows:

AreaEventType::＝ENUMERATED{enteringArea(0)，insideArea(1)，outsideArea(2)，leavingArea(3)，...}
Expression zone issue type comprises and enters the zone, in the zone, outside the zone, leaves four types in zone.
In addition, the related definition of GeographicTargetAreaList is:
GeographicTargetAreaList::＝SEQUENCE(SIZE(1..maxNumGeoArea))OF?GeographicTargetArea
GeographicTargetArea::＝CHOICE{
circularArea CircularArea，
ellipticalArea EllipticalArea，
polygonArea PolygonArea，
...}
The expression target area can be one or more zones, and the shape in zone can be circle, ellipse or polygon etc.
Owing to the trigger condition that can only realize based on the existing parameter of SUPL based on fixed area, therefore, need the element of this message be expanded for realizing relative conditon, extended method is as follows:
(1) increases new AreaEventType type---relativeArea (4), represent the zone of this zone for determining based on the position of reference object.
I.e. expansion back the new of AreaEventType is defined as follows:
AreaEventType::＝ENUMERATED {enteringArea(0)，insideArea(1)，outsideArea(2)，leavingArea(3)，relativeArea(4)...}
(2) for AreaEventParams increases new parameters R elativeGeographicTargetArea, the zone that expression is determined based on the reference object position, it is defined as follows:
RelativeGeographicTargetArea::＝SEQUENCE
{
