Detailed description of the invention
Fig. 1 is the schematic flow sheet of the determination embodiment of the method one of group of the present invention center member, such as Fig. 1
Shown in, the executive agent of the present embodiment can be the device of the determination method performing this group center member,
Such as background server, the method for the present embodiment includes:
The positional information of each UE in step 101, collection group.
First the composition of group is illustrated, how much based on group's trip number of members, can be to one-tenth
Member divides as follows: comprise all members is referred to as system；System again is divided into multiple group；Often
The member of identical or different quantity can be comprised in individual group.From granularity angle it is from small to large: member,
Group, system.Secondly, the role of member can be divided into: group member, DBMS member, group
Center member, system centre member etc..So-called group/system centre member can be that group/system is specified
Member, is similar to the role of guide；Can also is that according to the real-time geographic position of each member in group/system
Putting, what iterative computation obtained is easy to the member that group/system each member interior converges to Central Position position.
Further, member and/or group have its respective attribute list, this attribute list include state, position,
Priority, playing role (rank and file or center member) etc..Member and group in attribute list are equal
Can be ranked up by pre-set priority, each member is by prioritization in group, excellent by group between group
First level sequence.
Determination for group center member can be that system is specified, it is also possible to real-time according to member
Positional information is determined and updates, and the present invention is discussed in detail the determination side of latter group center member
Method.For the ease of management member data, can set up classification data base, this data base includes general
Logical member data, group's center member data, system centre member data etc..When member role (center
Member or rank and file) or state (positional information) update time, corresponding data synchronized update.
Due to logically contiguous by mobile terminal network between each member, do not limited by physics region, can be individual
People member is unit, or group of group is unit, the system trip network of composition safety, it is simple to extension,
It is effectively improved redundancy and the safety of trip member, and improves the degree of freedom of group's trip, it is simple to realize group
The collaborative monitoring of body trip, security alarm etc..
In this step, including at least one member in group, each member carries mobile terminal UE
(User Equipment is called for short " UE "), in this mobile terminal, it is configured with global position system GPS
The location instrument such as (Global Positioning System is called for short " GPS ") or gyroscope.Position to UE
Put information gathering and set collection period, to realize the periodicity collection to member geographical position, it is also possible to root
Need according to system statistics, when member current location is acquired by needs, sends and gather UE position letter
The request message of breath is to obtain the current instant position information of UE.
Step 102, according to default center position, determine first between each UE and default center position
Spacing.
In this step, default center position can be determined according to the initial position of each member, as
Group member unification is from starting point, then default center position can be set as this starting point；If group
Member, then can be by carrying out cumulative asking from each different place to each member's initial position message
Averagely, this default center position is obtained.According to the positional information of each UE, ask for each UE pre-with this
If the distance value between center, the set of all first spacing in obtaining group.
Step 103, numerical values recited according to the first spacing carry out interval division to each UE in group,
And give weighted value to each after dividing is interval；Wherein, the weighted value of interval each UE interior is with corresponding
Interval weighted value is identical.
Concrete, first spacing of UE all in group is ranked up from big to small, basis after sequence
With the distance of default center location gap, each UE is subdivided into different intervals, and gives each interval
Giving weighted value, this weighted value distribution principle can be, the interval less with default center location gap is divided
Joining bigger weighted value, the weighted value that the interval distribution bigger with default center location gap is less, to add
The determination efficiency of fast group center member.
Step 104, according to the weighted value of each UE and each UE positional information, to default center position
It is updated, obtains the first center.
Concrete, according to the positional information of weighted value Yu each UE, recalculate new center,
Obtain the first center.Wherein, the positional information of UE can periodically collect, then step
Positional information in 104 can be the up-to-date positional information after updating, and this ensure that the first centre bit
The accuracy put.Wherein, the setting of collection period can be by those skilled in the art according to group center member
Determine that the factor such as the duration of process and the number of group member is determined.Such as, at active computer
The reason actual translational speed of speed, significantly faster than member, then can join the renewal frequency of positional information
Examine arithmetic speed to be set.
Step 105, according to the first center, determine second between each UE and the first center
Spacing.
Concrete, recalculate the center after each member and renewal, namely with the first center
Between distance, the set of all second spacing in obtaining group.
Step 106, according to the second spacing and default screening conditions, the UE in group is screened, go
Except the second spacing is unsatisfactory for presetting the UE of screening conditions.
Screen out according to the UE that default screening conditions are unsatisfactory for condition to the second spacing in group, with contracting
The little member's scope determining group center member.
Step 107, the UE number in group after screening is judged；If UE number is less than or equal to pre-
If number threshold value, perform step 109；If the number of UE is more than predetermined number threshold value, perform step 108.
Concrete, if the residue membership after Shai Xuan is still a lot, more than predetermined number threshold value, then may be used
To perform step 109, the position that updating location information is the first center of default center position is believed
Breath, screens member by iterating, the center that each iterative computation makes new advances, and removes
Some is member farther out apart from this center, until residue number of members reaches predetermined number threshold value, holds
Row step 108, finally to determine a center member in group.
Step 108, by the positional information that updating location information is the first center of default center position,
To each UE repeated execution of steps 102 in group after screening to step 108.
Step 109, each UE determined according to each UE positional information after screening in group second in
Heart position；And determine the center member that UE be group nearest with the second center position.
Concrete, when after screening, membership is less, UE number, less than or equal to after predetermined number threshold value, is counted
Calculate the spacing with this second center in residue member, then the member selecting spacing nearest is in group
Heart member.
The determination method of the group center member that the present embodiment provides, by each UE in collection group
Positional information；According to default center position, determine between each UE and default center position
One spacing；Numerical values recited according to the first spacing carries out interval division to each UE in group, and
Weighted value is given to each after dividing is interval；Wherein, the weighted value of interval each UE interior is with corresponding
Interval weighted value is identical；Weighted value according to each UE and each UE positional information, to presetting
Center is updated, and obtains the first center；According to the first center, determine each
The second spacing between UE and the first center；According to the second spacing and default screening conditions pair
UE in group screens, and removes the second spacing and is unsatisfactory for presetting the UE of screening conditions；To sieve
UE number in Xuan Hou group judges；If UE number is less than or equal to predetermined number threshold value, root
The second center according to each UE that each UE positional information determines after screening in group；And really
The fixed center member that UE be group nearest with the second center position；If the number of UE is more than
Predetermined number threshold value, is the first center by default center location updating, in group after screening
Each UE repeats said process, finally to determine the center member of group.The method is permissible
According to the real-time position information of member, quickly determine the center member in group, so that all in group
Member converges to center member, improves the efficiency of collecting of group member, and ensure that what group went on a journey
Safety, improves the degree of freedom of group's trip；And the method only needs successive ignition to be assured that
Going out center member, algorithm is simple, and amount of calculation is little, and accuracy is high.
Fig. 2 is the schematic flow sheet of the determination embodiment of the method two of group of the present invention center member, in reality
On the basis of executing example one, this embodiment includes:
The positional information of each UE in step 201, collection group.
Step 202, according to default center position, determine first between each UE and default center position
Spacing.
Step 203, the first spacing is carried out numerical values recited sequence；According to default number step-length to sequence after
The UE corresponding to the first spacing carry out interval division；According to the interval after dividing and default center position
Far and near give weighted value.
Wherein, the weighted value of interval each UE interior is identical with corresponding interval weighted value.This default number
Step-length can be set according to membership in group, and interval number, number of members and default number step
Long satisfied:
Presetting number step-length is Sa、Sr, wherein, Sa=SrOr Sa≠Sr, interval number is q, total number of persons
For m0, then Sa×(q-1)+Sr=m0。
Such as, number of members is 50, and preset number step-length being set to each interval unique step is 10, then will
50 members are divided into 5 intervals, every interval 10 members, to each interval weighted value that sets, and 5
5 weights of interval distribution, the weighted value in each interval by the distance between itself and default center position by closely
To being far gradually reduced.
Step 204, the weighted value of the positional information of UE with corresponding UE is weighted summation it is averaged,
Obtain the first center.
Assume that corresponding weights interval with q are: P1P2......Pq, these weights are the weights after normalization,
NamelyAgain the weighted value that the positional information of UE is interval with its place is weighted summation to take
Averagely obtain:Wherein, V1It it is the first center；j
Interval for jth, LiPositional information for i-th UE in front q-1 interval；LkInterval for q-th
The positional information of interior kth UE.
Step 205, according to the first center, determine second between each UE and the first center
Spacing.
With this first center V1For reference point, between second between each UE and the first center
Away from Δ (Li,v1), i=1......m0It is updated, each second spacing after being updated.
Step 206, default screening conditions include: preset screening number；Second spacing is arranged from big to small
Sequence；According to order descending after sequence, screen out successively and meet the second spacing institute presetting screening number
Corresponding UE.
Step 207, the UE number in group after screening is judged；If UE number is less than or equal to pre-
If number threshold value, perform step 209；If the number of UE is more than predetermined number threshold value, perform step 208.
Assume that n is iterations, then after each iteration, the number of members in group is m0m1......mn；m0For
Membership initial in group, m1For according to the first center V1After being calculated the second spacing, sieve
Remaining number after choosing, by that analogy, remains m after n iterationnIndividual member, wherein, mnIt is less than or equal to
Predetermined number threshold value.
Step 208, by the positional information that updating location information is the first center of default center position,
To each UE repeated execution of steps 202 in group after screening to step 208.
Step 209, each UE determined according to each UE positional information after screening in group second in
Heart position；And determine the center member that UE be group nearest with the second center position.
To mnIndividual member carries out calculated as below:Further according to residue mnThe centre bit of individual member
Put vn+1It is calculated residue mnMember and this vn+1Between separation delta (Li,vn+1), i=1......mn, take mnIn with should
vn+1Min (Δ (the L that spacing is minimumi,vn+1)) member is as final group center member.
Optionally, to the center member of each group in the system being made up of multiple groups, acquisition system
The positional information of UE, to step 209, determines system as this group, execution step 202 using system
Center member.
It was previously noted, how much based on group's trip number of members, member can be divided as follows:
Comprise all members is referred to as system；System can again be divided into multiple group；In each group permissible
Comprise the member of identical or different quantity.From granularity angle it is from small to large: member, group, system.
Secondly, the role of member can be divided into: group member, DBMS member, group center member, is
System center member etc..In order to accelerate system centre member constant speed degree really, and reduce amount of calculation, can be with
The representative that center member is a group in each group, passes through above-mentioned to the center member of each group
In step, the method matching of iterative approach show that the center of interior each group center member of approximation system is geographical
Position, and to select the member nearest away from this geographical position, center be system centre member, thus each group
The center member of group determines the center member of system.
Optionally, in addition to the determination method of above-mentioned group or system centre member, it is also possible to use static state rule
Ze Dui center member is determined, and this static rule can be preliminary election static point or static pre-determined route is
Reference object, the member of this reference object deviation minimum of chosen distance is group center member, also according to
This rule selects system centre member between each group center member.Bar is met when there being two or more member
During part, can become according in group or centered by between group, prioritization selects the member that priority is higher
Member.
Optionally, for when there being two or more member to meet group's center member condition in group, can
With according to presetting member's prioritization selection group center member；In like manner, when group center member has
When two or more members meet system centre member condition, system is according to the sequence choosing of default group priorities
Select system centre member.
Optionally, when current group/system centre member can not undertake center member role for some reason, can be actively
In group/system in highest-ranking member send actively change request, with according to circumstances by selecting rule
Center member is reselected from other members.
Optionally, when current group/system centre member can not undertake center member role for some reason, as occurred
(such as network signal interrupts, it is impossible to obtain the real-time position information of center member UE), system during fault
Detect this member's abnormality, then cancel this member center member role, in group other members/other
Group center member reselects group/system centre member.
Optionally, preset group's spacing threshold, be used for defining back gauge between group.When certain Liang Ge group center
Member is smaller than this default group spacing threshold, this Liang Ge group can merge into a Ge Xin group, and
It is in the new group after merging by the group center member that the former former priority of group priorities sequencing selection is higher
Heart member, each member sequence in new group, the group member that former priority is higher comes unit by set sequence
Before the group member that priority is relatively low.Additionally, group member can also ask to merge, by group voluntarily
The heart member file a request, and meets default merging condition and then merges, and presetting merging condition can be total people
Number is without departing from default group number max-thresholds, and group's spacing is without departing from merging max-thresholds etc..Merge
The maximum spacing that big threshold value need to meet for defining Liang Ge group to merge.
Optionally, for reducing complexity, it is achieved system internal loading is shared, and each group is by predetermined number model
Enclosing interior member composition, in group, number of members not can exceed that default group number max-thresholds, group's number
When reaching the upper limit, adding members should put under and close on other groups.Adding members's priority was in principle the most not both
There is member, after other members of its Xin Ru group should be come.
When certain group is split by needs, former group is continued to use in each new group group member sequence after fractionation
Internal sort, former group center member continues to serve as the initial center member of the new group in its place, other new groups
The center member of group is initially set the member that priority is higher.After initial center member sets, follow-up change
More follow the group's center member selection rule in above-mentioned steps 201～step 208.
Optionally, member can select other groups of moving into voluntarily, or according to circumstances member is moved into by system
Other groups.When member migrates between group, determine its prioritization according to preset rules, one
In the case of as, the impact brought group of moving into for reduction, in group, prioritization has precedence between group
Prioritization, is newly added in member should come group after former member.
Member can select other groups of moving into voluntarily, and as when trip task has adjustment, membership request moves into
Other groups.Now, member by this group center member to purpose group center member propose access please
Asking, purpose group center member judges whether this request meets transition condition, such as purpose group people after migration
Number is without departing from default group number max-thresholds, and this member and purpose group center member's spacing are less than pre-
If migrating max-thresholds etc..Migrate max-thresholds for define member move into certain group time need to meet with move
Enter the maximum spacing of group center member.Certain member is actively moved into other groups by system also dependent on situation,
As this member and purpose group center member are smaller than presetting minimum threshold between group, or this member with work as
Pre-group group switching centre member's spacing is more than spacing max-thresholds in group etc..Now, current by this member place
Group center member notifies that this member moves out message, after member confirms, sends, to purpose group, the request of moving into,
Follow-up flow process is ibid.
Optionally, add group when there being newcomer to ask, select to move according to the first principle apart from rear priority
Enter group.Calculate this member and each group center member's spacing, select minimum spacing place group, it is judged that
Whether meet condition of moving into, if the purpose group number after moving into is without departing from max-thresholds etc., satisfied then to
It sends request message of moving into, and follow-up flow process ibid, is unsatisfactory for then sorting according to spacing, selects remaining group
The request that in group, spacing is minimum is moved into, by that analogy.When moving into condition when there being two or more group to meet,
Sorting according to group priorities, the group appeal selecting priority level higher is moved into.
