In any of the embodiments of the present invention, preferably, before the terminal acquires the display marks of n terminals including itself at the position to be shared in the position sharing group corresponding to the position sharing mode, if the number of the terminals at the position to be shared is too large, especially when the number n of the terminals is greater than T, a hierarchical clustering display manner is adopted to limit the number of people in each position sharing group, so that the sharing of the position information is quicker. The specific hierarchical clustering process takes a terminal for establishing a location sharing group as an example, as shown in fig. 4, and mainly includes:
step S401, the terminal establishes a position sharing group in M position sharing groups, and establishes or joins a position sharing group leader group, wherein the position sharing group leader group is a position sharing group comprising the terminal and the rest terminals establishing M-1 position sharing groups;
in step S401, a value of M is an integer part of a value obtained after the number n of terminals is the root number, and only one terminal in the position sharing group leader group is a party for establishing the position sharing group leader group;
that is, the terminal that establishes the sharing location group needs to join a sharing location group leader group in addition to joining the sharing location group established by itself, and it can also be an establisher of the sharing location group leader group;
step S402, the terminal displays M position sharing groups and the position sharing group leader group in a layering way in a position sharing mode;
in step S402, after M shared position groups and shared position group leaders are displayed hierarchically, in the process of executing the method for sharing position information shown in fig. 1, terminals located in the shared position group and the shared position group leaders are displayed by using corresponding Mark marks.
It should be noted that the position information sharing performed by hierarchical clustering disclosed in the embodiment of the present invention is not limited to the case where the number n of terminals is greater than T, and when the number n of terminals is not greater than T, hierarchical clustering display may be performed.
In the embodiment of the present invention, a process of position sharing for each terminal specifically for hierarchical clustering is described in detail by the following example:
for example: currently, 28 terminals to be shared have an integer part of a value obtained after the value of the group dividing mode M is the number n of the terminals and the number n of the terminals is the root number, and the 28 terminals to be shared can be divided into 5 groups, wherein each group does not exceed 6 terminal users;
it should be noted that the group of less than 6 end users is supplemented with corresponding empty slots during the sampling of consecutive slots.
The first layer is a team leader layer, and A1, A2, A3, A4 and A5 represent the leaders of 5 position sharing groups to be established, namely A1, A2, A3, A4 and A5 are located in the same position sharing group leader group, wherein one of the leaders is the creator of the position sharing group leader group;
the second layer is a position sharing group established by a1, a2, A3, a4, a5, respectively, and it is assumed that there are 6 terminals in each position sharing group established by a1, a2, A3, and 5 terminals in each position sharing group established by a4, a 5.
As shown in fig. 5, the layered concrete representation is:
a1 is the 1 st position sharing group of group leader, the members are (A1, 11, 12, 13, 14, 15);
a2 is the 2 nd position sharing group of group leader, the members are (A2, 21, 22, 23, 24, 25);
a3 is the 3 rd position sharing group of group leader, the members are (A3, 31, 32, 33, 34, 35);
a4 is the 4 th position sharing group of group leader, the members are (A4, 41, 42, 43, 44, K);
a5 is the 5 th position sharing group of group leader, the members are (A5, 51, 52, 53, 54, K);
position sharing group leader group consisting of 5 group leaders: members are (A1, A2, A3, A4, A5);
wherein K denotes a blank time slot; only two groups of a1 and a5 are shown in fig. 5;
in the embodiment of the present invention, after the group is divided into 2 layers, the total time for refreshing all terminals in each position sharing group is correspondingly shortened because the number of terminals in a single group is reduced.
Suppose that each terminal updates location information and uploads the least time-consuming time slot T required for refresh0Denotes, that is, at T0The time slot is used for simultaneously completing the refreshing and uploading of the position information, and under the condition of not carrying out hierarchical clustering, the 28 terminals all need 28T0The location information can be refreshed all once.
Referring to fig. 5, after hierarchical clustering, the refresh time of the position sharing group leader group formed by the above 5 group leaders is 5T0And the time for refreshing the shared group of each position is 5T0Or 6T0(ii) a To keep consistency, a blank time slot K is added in each position sharing group established by the position sharing group length group A4 and A5, and the terminal of the 6 position sharing group only needs 6T at least0The location information may be updated once.
It should be noted that, if the current terminal is a creator of the location sharing group, the current terminal needs to start the location sharing group and the location sharing group leader group at the same time, at this time, a plurality of location sharing groups (including the location sharing group leader group) may be displayed simultaneously in a manner of bisecting a display window on an operation interface of the terminal, or displayed in turn in a manner of switching windows.
In the technical scheme disclosed by the embodiment of the invention, 28T is originally needed by the layered clustering mode0The updating and uploading of the position information of all the terminals are completed, after 6 groups are established hierarchically, the refreshing and uploading of the position information of all the terminals only needs 6T for the common terminals (the own position sharing group is not established)0The 22 empty time slots are saved, that is, the 22 empty time slots, the terminal does not need to refresh the location information and upload, which is equivalent to being in the power saving mode, and for the terminal establishing the location sharing group, the total number of the terminals of 2 groups is 11, and the minimum number of the terminals needs 11T0The time length can be used for refreshing the position information of all the terminals, and the terminal resources and the system overhead can be further saved based on the layered clustering mode.
Further, in the location sharing group as the location sharing group leader group, each terminal may perform location sharing according to the method for sharing location information shown in fig. 1.
