When being positioned to multiple terminals, server determines the location information provider of the terminal according to the Location Policy resource of each terminal, and Location Request is sent to the location information provider of each terminal one by one, the location information that each location information provider by positioning terminal returns is received, realizes positioning.But above-mentioned positioning method, a large amount of transfer resource can be consumed, and will lead to channel congestion.
In order to solve this problem, the embodiment of the present invention provides a kind of localization method and corresponding intrument, technical solution of the present invention is described in detail below by attached drawing and specific embodiment, it should be understood that the specific features in the embodiment of the present invention and embodiment are the detailed description to technical solution of the present invention, rather than the restriction to technical solution of the present invention, in the absence of conflict, the technical characteristic in the embodiment of the present invention and embodiment can be combined with each other.
Term " includes " and " having " and their any deformation in description and claims of this specification, it is intended to cover and non-exclusive includes, such as, the process, method, system, product or equipment for containing a series of steps or units those of are not necessarily limited to be clearly listed step or unit, but may include other step or units being not clearly listed or intrinsic for these process, methods, product or equipment.
In a first aspect, the embodiment of the present invention provides a kind of localization method, referring to Fig. 3, for the flow diagram of the localization method, which includes the following steps:
Step 101: server is when positioning group, according to the group prestored positioning each group membership from multicast address to group location information provider's multicast Location Request, position the address information of the location information provider for each group membership that multicast address includes group, location information of the Location Request for the group membership of request group.
Specifically, each group membership of group is one by positioning terminal, location information provider can have following implementation:
First, the location information provider of member is group membership itself, i.e., group membership can determine the location information of itself by the locating module of itself, and the location information of itself is returned to server.
Second, the location information provider of group membership is the location-server in bottom-layer network.For example, common carrier is provided with positioning function, the location-server of common carrier preserves the location information of group member, and server can send Location Request to the location-server in bottom-layer network, and then know the location information of group member.In actual conditions, the location-server of bottom-layer network is normally based on position deployment, and therefore, the corresponding location-server of group member for being usually located at different zones is different.
Thirdly, the location information provider of group membership is shared device, specifically, the location information of group membership is preserved in shared device, and the location information of group membership is shared, when server positions group membership, it can send and request to the shared device, the location information of the shared group membership of the request shared device.
Multicast (Multicast) refers to sender information while passing to one group of destination address (that is, multicast address), and information need to only be transmitted once on every network link, and only when link bifurcated, information can be just replicated.
In the embodiment of the present invention, the group is prestored in server is set to positioning multicast address, the positioning multicast address includes the address information of the location information provider of each group membership of group, therefore, server can be according to positioning each group membership location information providing multicast Location Request of the multicast address to group, the location information provider of each group membership can be not only made to receive Location Request, information redundancy caused by multiple copies in same chain there are Location Request can also be avoided, and then saves transfer resource.
In addition, the trigger condition that server positions group includes: first, server receives the Location Request of Location Request end transmission positioned to group, server responds the request, triggers group's positioning flow.Second, being provided with timer on server, when timer time reaches, trigger and the group of group is positioned, in actual conditions, when timer time reaches, timer zero, into next time-count cycle, periodically group is positioned to realize.
Step 102: server receives the location information that the location information provider of each group membership of group returns.
Specifically, the location information provider of each group membership of group is in the positioning for receiving server multicast After request, the Location Request is responded, the location information of the group member positioned, the location information that server returns to the location information provider for receiving group member are returned to server.
In above-mentioned technical proposal, server sends Location Request to the location information provider of group member in a manner of multicast, and the location information that the location information provider for receiving each group member returns, and realizes the positioning to group.Due to sending Location Request by the way of multicast, what is used in compared to the prior art sends the scheme of Location Request one by one, not only reduce the transinformation in transmission link, and then improve the utilization rate of air interface transmission resource, but also the congestion because alleviating transmission link, transmission rate is improved, time delay is reduced, and then it is time-consuming to reduce positioning.
Optionally, further include following steps referring to Fig. 4 after step 102 in the embodiment of the present invention:
Step 103: the location information of each member of received group is carried out mixed poly-, generation group's location information by server；
Step 104: server to Location Request end return mixed consor at group's location information.
Specifically, poly- (mashup) is mixed to refer to permeating different information the information of Xiang Xin, in the embodiment of the present invention, the location information of each member of received group is carried out mixed poly- processing by server, obtain one new information, location information comprising each group membership in group in the new information, which is group's location information.
In the embodiment of the present invention, server includes: first, Location Request end has initiated to obtain the request of group's location information to server to the case where Location Request end return group's location information；Second, server timing updates the location information of each group membership of group, and after updating the success of group's location information, by updated group's location information restoring to normal position request end.
In above-mentioned technical proposal, server, which mixes the location information of each group membership of group, to be gathered for group's location information, and mixed poly- obtained group's location information is returned to Location Request end, middle server returns to the mode of the location information of each group membership of group to Location Request end one by one compared to the prior art, transfer resource when above-mentioned technical proposal of the embodiment of the present invention can be effectively reduced from server to Location Request end restoring to normal position result occupies, and improves transfer resource utilization efficiency.Moreover, since the location information of entire group to be stored in an information (that is, group's location information), data processing and data management are carried out convenient for server and Location Request end.
Optionally, in the embodiment of the present invention, before step 101, with continued reference to Fig. 4, further include step 105: server judges whether the network that Location Request is sent to the location information provider of each group membership of group supports multicast, if the network support multicast, thens follow the steps 101.
Specifically, in actual conditions, network locating for the location information provider of each group membership of group may not support multicast, in this case, Location Request can not be sent to the location information provider of each group membership by server by multicast, so, server will first determine whether network locating for the location information provider of each group membership of group supports multicast according to the positioning multicast address of group, if supporting multicast, 101 are thened follow the steps；If not supporting multicast, execution can have the following two kinds operation: first, to location information provider's unicast Location Request of each group membership；Second, location information provider's multicast Location Request of the group membership for supporting multicast, and for not supporting location information provider's unicast Location Request of multicast.By determining network support multicast before multicast Location Request, it can be avoided the transmission failure of Location Request, guarantee the reliability that Location Request issues.
Optionally, further include step 106 with continued reference to Fig. 4 before step 101 in the embodiment of the present invention: server determines that group includes at least two members.
Specifically, whether the quantity for judging the group membership of group is reached two by server before executing step 101, if group includes at least two members, 101 are thened follow the steps, multicast Location Request；If group only includes a group membership, Location Request is issued by the way of unicast.
When it is implemented, not limiting the sequencing between the two when simultaneously including step 105, step 106 in positioning flow, it can be to first carry out step 105, determining that support group sowing time executes step 106；It is also possible to first carry out step 106, after determining that group includes two group memberships, executes step 105.
Optionally, in the embodiment of the present invention, when executing step 104, server first authenticates requestor, after authenticating successfully after the request for receiving the location information that requestor obtains group, mixed poly- obtained group's location information is returned to requestor again, to guarantee the safety of information.
Optionally, in the embodiment of the present invention, if execute step 102, server directly receives the location information that the location information provider of the part group membership in group returns, and the location information of remaining group membership obtains failure, when there is location information of the Location Request end to server request group, then the location information of the group membership obtained can be mixed and be gathered for group's location information by server, meanwhile mixed poly- obtained group It also include the information of the group membership of positioning failure in location information, server returns to group's location information to Location Request end.
In addition, if server fails to obtain the location information of all group memberships of group, when there is location information of the Location Request end to server request group, server directly can return to error identification to Location Request end, show that server is current and the location information of all group memberships of group has not been obtained.
In the embodiment of the present invention, the positional parameter of group is realized in the form of the attribute of resource, resource be in machine communication system to physical entity (such as, sensor, positioning device), application object (such as, control the program of positioning flow, the program that is handled positioning result), the general designations of data, it can be described with resource structures, it is independent addressable, it can be searched and find, and there is unique mark, usually with universal resource identifier (English: Uniform Resource Identifier；Referred to as: URI) it is used as resource identification.Resource includes attribute information, also be can wrap containing child resource, the positional parameter of group is to include among the attribute information of the attribute information or child resource that position relevant resource in the server.
In actual conditions, Location Request end needs to create the relevant resource of positioning on the server before positioning, and the positional parameter of group is preserved in positioning relevant resource.It is before step 101, further comprising the steps of referring to Fig. 5 in the embodiment of the present invention:
Step 107: server is according to the information creating group resource of group member.
Specifically, group member information can be sent to server for group creating end, or founder directly carries out input operation input on the server.Wherein, it group creating end can be identical with Location Request end, it can not also be identical, for example, administrator's first of carrier creates group, fleet by office computer, office computer is group creating end, and administrator's first assigns the permission that administrator's second obtains fleet's location information, then administrator's second can request the location information of fleet by handheld terminal to server, at this point, the handheld terminal of administrator's second is Location Request end.
Group creating end sends the request of creation group (Group) resource to server, the information of group member is carried in request, such as the mark of group member.Server respond request, create group's resource, will group creating end send request in include by positioning terminal association in groups.
It is a kind of schematic diagram of resource structures of Group resource, the attribute of Group resource includes: group name (Group Name) referring to Fig. 6；Group creating end (Creator)；Group member identifies (Member IDs), by adding in the Member IDs of Group resource by the mark of positioning terminal, this can be added in group by locating resource, makes the group membership of its member group.In actual conditions, Group resource can also include other attributes and child resource according to different requirements, and this will not be detailed here for the embodiment of the present invention.
