Description

Group change method and device

The present application claims the priority of the Chinese Patent Application, filed on Feb. 9, 2017, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present application relates to the field of communication technologies, and in particular, to a group change method and apparatus.

Background technique

Vehicle-to-Everything (V2X) communication is a hot topic in the communication field, and was officially established at the 3GPP RAN#67 meeting in 2015. V2X communication mainly includes three aspects:

Vechile-to-Vechile (V2V): Communication between the On Broad Unit (OBU) on the car.

Vechile-to-Infrastructure (V2I): Communication between a car and a Road Side Unit (RSU).

Vechile-to-Pedestrian (V2P): Communication between cars and pedestrians.

Among the above three V2X communication methods, V2V has the highest latency requirement. The specific delay requirement is that the end-to-end delay cannot exceed 100 ms.

Enhanced V2X (enhancement of Vehicle-to-Everything, eV2X) communication is an evolution of V2X communication. Based on the workshop communication based on Long Term Evolvement (LTE) network, V2X further adopts LTE/5G technology. The V2X is applied to intelligent application scenarios such as team cooperative driving, automatic driving, sensor information sharing and remote driving. In eV2X, vehicles, pedestrians, and drive test equipment support the ability to interact with a wider variety of information (such as vehicle sensor data, driving directions, etc.), more collaboration (such as how to team up, collaborative driving, coordinated risk aversion) and more. Vehicle driving modes (such as fleet driving, automatic driving, etc.) make V2X technology more flexible, safe and reliable to meet the needs of intelligent transportation.

The team is the application scenario of the eV2X. When the vehicle is running on the road, the fleet can be dynamically adjusted. The generator team is responsible for the management of the team. The car and the car are driven at a small distance (1 meter or 2 meters). How the train travels.

Each team can be used as a terminal group. However, there is no direct merge and split solution for multiple terminal groups. The group members need to join the group or leave the group one by one. The signaling overhead is large, the process is complicated, and the efficiency is complicated. Lower, not applicable to the consolidation and splitting of multiple fleets in an eV2X application scenario.

detailed description

The application scenario of the eV2X includes the fleet scene. The fleet consists of several vehicles forming a fleet. The first vehicle is responsible for driving. There is a small distance between the vehicle and the vehicle (1 meter or 2 meters) to form a similar train. .

Team members form a group in which members of the group send information that only members of the group can resolve. The application scenario may include combining two or more fleets into one fleet, that is, involving the merger of the terminal groups, or including splitting one fleet into multiple teams, that is, splitting involving the terminal groups.

The embodiment of the present application provides a group change scheme, so that the entire group of members can join or leave a group together, so that the group members do not need to join the group and/or leave the group one by one, reduce signaling overhead, simplify the group change process, and improve Group change efficiency.

For example, referring to FIG. 1, a method of integrally grouping group 2 (ie, a second terminal group) into group 1 (ie, a first terminal group) includes:

Step 1: The group 2 manager terminal (referred to as the manager) issues a group join (ie, merge) request to the group 1 manager, which includes the group size (group 2 members) information of the group 2.

It should be noted that this step is not necessary, and the group size information of the group joining request is not necessary.

Step 2: The group 2 manager starts the timer T1 after the request is sent. If the group join message of the group 1 manager is not received within the time T1 (that is, before the T1 timeout), the group join failure is considered, and the group can be resent. Request, or abandon joining group 1 depending on the situation (for example, the number of times the request failed more than the preset maximum number of times).

Step 3: Before T1 times out, Group 1 agrees that Group 2 joins, and Group 1 Manager sends a Consent Group Join message to Group 2 Manager, that is, a group change message indicating that Group 2 and Group 1 are combined.

Step 4: The group 2 manager sends group change information to all members of the group 2, which includes the manager of the new group (ie, the group 1 manager) and the group ID (ID of the group 1) information.

Step 5: The group 2 manager starts the timer T2 after issuing the group change information to the member terminals (members) in the group 2.

Step 6: Before the T2 timeout, all members of the group 2 feed back the group change confirmation message to the group 2 manager.

Optionally, if any member of the group 2 does not feedback the group change confirmation message within the T2 time, the group change information needs to be separately sent to the corresponding member and the T2 is restarted. If the group retransmission group changes the information after N times, the group 2 is not obtained. The group change confirmation message fed back by the member feeds back the group join failure message to the group 1 manager.

Step 7: The group 2 manager sends a group join completion message to the group 1 manager, which contains information of the members of the group 2. At this point, Group 2 Manager and all members of Group 2 become members of Group 1.

Step 8: The group 1 manager sends a group member change message to all group 1 members (including the original group 1 member and the newly added manager and member of the original group 2) for notifying the members of the group of the change and the changed Member information.

It should be noted that the above-mentioned timers T1 and T2 are not necessarily required to be activated, but are preferred operations, and the timing duration thereof may be determined according to actual needs, and the same applies to the following embodiments.

For the same reason, the example of the group splitting process is as follows:

For example, referring to FIG. 2, the method of group 1 splitting into group 1 and group 2 includes:

Step 21: Inter-group member exchange information, determine to leave group 1, separate group 2, and determine group 2 manager.

If the group 1 manager determines to split the group 1 according to the fleet information and split the group 2, skip step 21.

Step 22: The group 2 manager issues a group split request, that is, a group change request, to the group 1 manager, which includes the group 2 size information (the number of members of the group 2).

If the group 1 manager determines to split group 1 according to the fleet information and splits group 2, step 22 is skipped.

Step 23: The group 2 manager starts the timer T1 after issuing the request. If the group split message of the group 1 manager (ie, the group change message) is not received within the time T1, the group splitting is considered to be failed and can be resent. Group split requests, or abandon group 1 as appropriate.

If the group 1 manager decides to split the group 1 based on the fleet information, step 23 is skipped.

Step 24: Group 1 agrees that group 2 is split out, or group 1 manager determines to split group 1 according to the fleet information, and group 1 manager sends group split message (ie group change message) to group 2 manager.

Step 25: The group 2 manager sends group change information to all members of the group 2, including the manager of the new group and the group ID information, that is, the information of the IDs of the group 2 manager and the group 2.

Step 26: The group 2 manager starts the timer T2 after issuing the change information to the members in the group 2.

Optionally, if any member of the group 2 does not feedback the group change confirmation message within the T2 time, the group change information needs to be separately sent to the corresponding member and T2 is restarted. If the group change confirmation message of all the members is not obtained after the group change information is transmitted N times, the group split manager fails to feed back the group split failure.

Step 27: Before the timer T2 times out, all members of the group 2 feed back the group change confirmation message to the group 2 manager.

Step 28: The group 2 manager sends a group split completion message (ie, a group change completion message) to the group 1 manager, which contains information of the members of the group 2.

At this point, Group 2 Manager and all members of Group 2 leave Group 1 and Group 2 is established separately.

Step 29: The group 1 manager sends a member change message to all group 1 members (the remaining group 1 members except the split group 2 member) to notify the group members of the change.

Step 29a: The group 2 manager sends a member change message to all group 2 members to notify the group members of the change.

It should be noted that the group members only accept the orders of the group manager of their own group or the new group manager appointed by the group manager.

For another example, referring to FIG. 3, the method for splitting group 2 from group 1 includes:

Step 31: Interacting information between several members in the group, determining to leave group 1, separately establishing group 2, and determining group 2 manager.

If the group 1 manager determines to split the group 1 based on the fleet information, step 31 is skipped.

Step 32: The group 2 manager issues a group split request (ie, a group change request) to the group 1 manager, which includes the group 2 size information (the number of members of the group 2).

If the group 1 manager determines to split group 2 from group 1 based on the fleet information, step 32 is skipped.

Step 33: The group 2 manager starts the timer T1 after issuing the request.

If the group split message of the group 1 manager is not received within the time T1, the group splitting is considered to be unsuccessful, the group split request may be resent, or the group split may be abandoned according to the situation.

If the group 1 manager determines to split group 1 based on the fleet information, step 33 is skipped.

Step 34: Group 1 agrees that group 2 is split out, group 1 manager sends a consent group split message to group 2 manager, or group 1 manager directly decides to split group 2 from group 1, and appoints group 2 Manager.

Step 35: The group 2 manager sends a group split confirmation message to the group 1 manager.

Step 36: The group 1 manager sends group change information to all members of the group 2, including the manager of the new group and the group ID information, that is, the information of the manager of the group 2 and the ID of the group 2.

Step 37: The group 1 manager starts the timer T2 after issuing the group change information to the members in the group.

Optionally, if any member of group 2 does not feedback the group change confirmation message within T2, it is necessary to separately send the group change information to the corresponding member and restart T2. If the group change confirmation message of all members is not obtained after the group change information is sent N times, the group splitting fails.

Step 38: All members of Group 2 feed back the group change confirmation to the Group 1 manager.

It should be noted that, in the embodiment of the present application, the change of all members in the group may be completed at one time, or the change of some members may be completed first. Therefore, it is not limited to the group 1 manager must receive all members of the group 2 to manage the group 1. The feedback group change confirmation message can be used to perform subsequent operations. After receiving the group change confirmation message to the group 1 manager in the T2 time, the group change can be performed on the members of the feedback group change confirmation message. operating.

Step 39: The group 1 manager sends a group split completion message to the group 2 manager, which contains information of the members of the group 2.

At this point, Group 2 Manager and all members of Group 2 leave Group 1, and after receiving this message, Group 2 members only receive commands from Group 2 Manager.

Step 310: The group 1 manager sends a member change message to all group 1 members (the remaining group 1 members except the split group 2 members).

Step 310a: The group 2 manager sends a member change message to all group 2 members.

It should be noted that the group members only receive the commands of the group manager of their own group or the new group manager appointed by the group manager.

In the embodiment of the present application, the message interaction between the terminal (or the user equipment (UE)) can be performed in the following manner:

Method 1: A signaling layer (PC5-signaling) message of direct communication between direct communication interfaces (PC5 interfaces) between terminals.

Method 2: Radio Resource Control (RRC) message of the PC5 interface.

Mode 3: Media Access Control (MAC) Control Unit (CE) of the PC5 interface.
