Abstract
A method for tracing the location in wireless network includes following steps: builds a group; sets various parameter for the group; invites several movable target to joint the group; starts the tracing monitor service; the tracing system enquiries the generic information of the traced target; the tracing system enquiries the current information of the traced target; based on the current information of the traced target and warn triggering condition makes calculation; based on the above result decides if the warn is needed; if the warn triggering condition is met, then starts the emergency processing; if the warn triggering condition is not met, then waits for a time to make next tracing. The invention also provides a tracing system comprising; wireless core network, application server, location server, movable terminal and location tracing system (LTS). The location server gets the location information of movable terminal through the wireless core network and sends it to the location tracing system, the location tracing system provides the service to users through the application server.
Description
Technical field
The present invention relates to location-based tracking and tracking system in a kind of wireless network, relate in particular to location-based tracking and the tracking system on a kind of 2.5G of being applied in or the 3G wireless network with alarm function.
Background technology
Such a case is usually arranged, have lineup group to wish to keep in touch mutually, and when having special event to take place, carry out relevant rapidly emergency processing in specific situation and place.Suchlike situation can occur in such as rescue attempt, exploration, disaster event analysis, travel, spends a holiday or the like, and the mutual intellectual between this each group member has been played the part of important role in the information sharing of whole group of maintenance.
According to market survey, expect in the near future for the demand of security monitoring service and to have great rising, in traditional safety system market, most of tracking systems are very limited in fact, mainly be in the environment of a sealing because of these system works, it is so-called local trace system, in addition, the signaling that the mechanism of these monitoring objects is based between watch-dog and the object transmits, generally when can not receive signaling or signal, watch-dog just can report to the police, and these systems are very strong to the dependence of its specific signaling, do not have portability.
Along with the development of global positioning system, obtain positional information and will be no longer dependent on traditional signal transmitting station, thereby enlarged the coverage of tracking system at present.But global positioning system equipment and usage charges are extremely expensive, use the target of this system also very remote from ordinary people's group energy, furthermore, the principle of supervisory control system still depends on the traditional tracking system principle-transmission spoken of the front and the simple signaling process between the accepting device, and lacks high-rise more complicated service logic.
In current wireless network, this real time information intercommunication and real-time tracking are very expensive and unpractical, further, under the situation that aforesaid lineup group wishes to keep in touch mutually in specific situation and place, when urgent, it is impossible especially that the lineup carries out track following to its group member that wanders away rapidly, also do not have so a kind of mechanism to store group member's movement track.
Summed up, there are a lot of restrictions in existing position-based information trace system, has hindered the use of domestic consumer, for example:
Expensive special-purpose terminal equipment;
Do not have the notion of group, just within the specific limits each object is followed the tracks of separately;
There is not corresponding high-rise complicated business logic;
Monitoring objective is in the environment of sealing;
Follow the tracks of between individuality and do not have mutual intellectual;
Every character of dynamically change group of tracking group, as alert if, monitoring range, personnel's increase and decrease or the like;
It is single that information transmits media.
Summary of the invention
The purpose of this invention is to provide location-based tracking and tracking system in a kind of wireless network, can be applied on 2.5G or the 3G Radio Network System, provide global real-time tracking service to the user, can keep trackability between each group member at the appointed time, intellectual and real time information intercommunication mutually, and provide record, calculating and logic high level to judge the enforcement mechanism of each group member's movement track.The equipment of this tracking and tracking system and usage charges will be that the general population can bear.
To achieve these goals, the present invention adopts following technical scheme:
Location-based tracking in a kind of wireless network may further comprise the steps:
A. set up a group;
B. set the parameters of this group;
C. several moving targets are defined as this group membership, these group memberships can be tracked;
D. start tracing monitor service;
E. tracking system is inquired about the general information of tracked target;
F. tracking system is inquired about the current information of tracked target;
G. calculate according to the current information and the alarm triggered condition of tracked target;
H. the result who calculates according to step g) judges whether the needs alarm, if desired, and to step I), do not need then to arrive step j);
I. satisfy the alarm triggered condition, start emergency response mechanism;
J. satisfy the warning trigger condition, then wait for behind the certain hour to follow the tracks of next time to step f).
Location-based tracking system in a kind of wireless network comprises wireless network, portable terminal, and application server, location server and positioning control system are characterized in:
Application server links to each other with described radio core network, for described positioning control system provides the platform support;
Location server links to each other with described positioning control system with described radio core network, obtains the positional information of described portable terminal and offers described positioning control system by described wireless network;
Positioning control system links to each other with described location server with described application server, utilizes described application server to provide follow-up service to the user, finishes each step of above-mentioned tracking.
Owing to adopted technique scheme, the present invention is compared to prior art, has following advantage, being different from traditional positioning control system needs the system manager to set/dispose, applied for that the usufructuary general user of native system just can dynamically independently create and group is followed the tracks of in management, intervention that need not the system manager, thus privacy of user protected; Reduced and started the intermediate link of emergency treatment program, thereby improved emergency response speed; The center of following range, promptly object of reference can be arbitrarily movable object space, can be static object space also, can be the arbitrary member of this trackings group, also can be other tracking arbitrary members of group, also can be the fixed object that does not belong to any tracking group; It is unrestricted to follow the tracks of the group member of group quantity; The tracking group member of group forms situation and can dynamically update as required, that is to say that any tracked object can at any time add or leave tracking group.
