Fleet member forms a group, and the information for only having group membership that can parse is sent mutually between group member.Its In application scenarios may include that 2 or multiple fleets are merged into a fleet, that is, be related to the merging of set of terminal, can also include One fleet splits into multiple fleets, that is, is related to the fractionation of set of terminal.

The embodiment of the present application gives a group change scheme so that and whole group member can be added or leave jointly a group, from It carries out addition group one by one without group membership and/or leaves the operation of group, reduce signaling overheads, simplify group change process, improve Group change efficiency.

For example, with reference to Fig. 1,2 (i.e. second terminal group) whole groups of group are merged into the method packet of 1 (i.e. first terminal group) of group It includes：

Step 1：2 manager terminals of group (abbreviation manager) send out a group addition to 1 manager of group and (merge) request, wherein Include group scale (2 memberships of group) information of group 2.

It should be noted that this step is not necessary, the group size values in request are added nor necessary in group.

Step 2：2 managers of group start timer T1 after sending out request, if do not had within the T1 times (i.e. before T1 time-out) There is the group for receiving group 1 manager that message is added, then it is assumed that failure is added in group, can retransmit a group addition request, or according to feelings Condition (such as it is more than default maximum times to ask the number of failure) abandons addition group 1.

Step 3：Before T1 time-out, 1 agreement group 2 of group is added, and 1 manager of group sends the addition of agreement group to 2 managers of group and disappears It ceases, that is, is used to indicate group 2 and group 1 is combined group simultaneously and changes message.

Step 4：2 managers of group are to 2 all member's transmission group modification informations of group, wherein (organizing 1 comprising the manager newly organized Manager) and group ID (ID of group 1) information.

Step 5：2 managers of group member terminal (abbreviation member) into group 2 starts timer T2 after sending out group modification information.

Step 6：Before T2 time-out, 2 all members of group change confirmation message to 2 manager's feedback groups of group.

Optionally, it if organizing 2 any members within the T2 times does not feed back a group change confirmation message, needs to corresponding member Independent transmission group modification information simultaneously restarts T2, if still without the group for obtaining organizing 2 members feedback after n times repeating transmission group modification information Confirmation message is changed, then failed message is added to 1 manager's feedback group of group.

Step 7：2 managers of group are added to 1 manager's transmission group of group and complete message, wherein including the information of 2 members of group.Extremely This, 2 managers of group become the member of group 1 with 2 all members are organized.

Step 8：1 manager of group (includes the manager of the former group 2 of original 1 member of group and Xin additions to all groups of 1 members And member) group membership's change message is sent, the information for the member after notifying group member that change and change occurs.

It should be noted that above-mentioned timer T1 and T2 is not required to be started, only preferred operations, timing length It can also be decided according to the actual requirements, and following embodiment is also the same.

Similarly, assembling and dismantling split flow is exemplified below：

Step 21：Interactive information between several members, determines and leaves group 1, independent establishment group 2 in group 2, and 2 pipe of group is determined Reason person.

It is determined according to fleet information if it is 1 manager of group and splits group 1, split out group 2, then skip step 21.

Step 22：2 managers of group send out a group fractionation request, i.e. group change request to 1 manager of group, wherein including 2 rule of group Mould information (2 memberships of group).

It is determined according to fleet information if it is 1 manager of group and splits group 1, split out group 2, then skip step 22.

Step 23：2 managers of group start timer T1 after sending out request, if not receiving 1 pipe of group within the T1 times The group of reason person splits message (organize and change message), then it is assumed that and group splits failure, can retransmit a group fractionation and ask, or according to Situation abandons fractionation group 1.

Judge to split group 1 according to fleet information if it is 1 manager of group, then skips step 23.

Step 24：1 agreement group 2 of group is split away, or determines that will organize 1 splits according to fleet information by organizing 1 manager, group 1 Manager splits message (i.e. group change message) to 2 manager's transmission groups of group.

Step 25：2 managers of group to 2 all member's transmission group modification informations of group, including the manager newly organized and Group id information organizes the information of 2 managers and the ID of group 2.

Step 26：2 managers of group member into group 2 starts timer T2 after sending out modification information.

Optionally, it if organizing 2 any members within the T2 times does not feed back a group change confirmation message, needs to corresponding member Independent transmission group modification information simultaneously restarts T2.If being changed really still without the group for obtaining members after transmission group modification information n times Recognize message, then splits failure to 1 manager's feedback group of group.

Step 27：Before timer T2 time-out, 2 all members of group change confirmation message to 2 manager's feedback groups of group.

Step 28：2 managers of group split to 1 manager's transmission group of group completes message (i.e. message is completed in group change), wherein Include the information of 2 members of group.

So far, 2 managers of group and 2 all members of group leave group 1, independent establishment group 2.

Step 29：1 manager of group sends to all groups of 1 members (remaining group of 1 member in addition to 2 member of group split away) Member changes message, for notifying this group membership to change.

Step 29a：2 managers of group send member to all groups of 2 members and change message, for notifying this group membership to become More.
