Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to updating group information related to a group, and in particular, to changing a group guide of a group. BACKGROUND

[0002] To meet the demand for wireless data traffic soaring since deployment of 4G communication systems, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a 'Beyond 4G Network' or a '5G Network'. The 5G communication system is considered to be implemented in higher frequency (mmWave) bands, e.g., 60GHz bands, so as to accomplish higher data rates. To decrease propagation loss of the radio waves and increase the transmission distance, the beamforming, massive MIMO, full dimensional MIMO (FD-MIMO), array antenna, an analog beam forming, large scale antenna techniques are discussed for use in 5G communication systems. In addition, in 5G communication systems, development for system network improvement is under way based on advanced small cells, cloud radio access networks (RANs), ultra-dense networks, a technology for coordination between cells, a cooperative multi-cell transmission technique, an interference mitigation and cancellation technology, a network building technology, and the like. In the 5G system, hybrid FSK and SQAM modulation, and sliding window superposition coding (SWSC) as an advanced coding modulation (ACM) technique, and filter bank multi carrier (FBMC), a non-orthogonal multiple access (NOMA), and a sparse code multiple access (SCMA) as an advanced access technology have been developed.

[0003] The Internet, which is a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of Things (IoT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of Everything (IoE), which is a combination of the IoT technology and the Big Data processing technology through connection with a cloud server, has emerged as a new paradigm for the IoT. As technology elements, such as "sensing technology", "wired / wireless communication and network infrastructure", "service interface technology", and "security technology" have been demanded for IoT implementation, a sensor network, a Machine-to-Machine (M2M) communication, Machine Type Communication (MTC), and the like have been researched. Such an IoT environment can provide intelligent Internet technology services that create a new value through collection and analysis of data generated from connected things. The IoT can be applied to a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances, and advanced medical services, through convergence and combination between the existing information technology (IT) and various industrial applications.

[0004] Meanwhile, various attempts have been made to apply the 5G communication system to IoT networks. For example, technologies such as sensor networks, MTC, and M2M communication can be implemented by beamforming, MIMO, and array antennas. The application of cloud RAN as the above-described big data processing technology can also be considered as an example of convergence between the 5G technology and the IoT technology. SUMMARY

[0005] TECHNICAL PROBLEM

[0006] In V2X communication, different entities such as vehicles, road side units (RSUs), application servers, and pedestrians exchange their own status information such as location, speed, and orientation with other vehicles, infrastructure nodes, and / or pedestrians nearby. V2X applications can use "consensus awareness" to provide more intelligent services for end users.

[0007] Among a plurality of use cases, one of the categories of use cases is related to vehicle platooning. In V2X, a platoon operates a group of vehicles in a closely connected manner such that the vehicles move like a train through a virtual rope attached between the vehicles. All vehicles in the platoon receive periodic data from a lead vehicle to implement platoon operations. A platoon creator is responsible for platoon management. A platoon leader plays an important role in platoon management. The platoon leader should update surrounding traffic data reported by group members in real time and report it to RSUs. At the same time, the platoon leader should receive RSU messages including road conditions and traffic information far from them in real time and share these RSU messages with platoon members. The platoon leader also coordinates mobility of the vehicle group, shares maneuver strategies and other information with each other.

[0008] The platoon leader needs to constantly remain active and continuously communicate with other vehicles, and the leader consumes more resources than other vehicles, so the leader vehicle can sometimes request the next vehicle to become a leader. Such communication can be made between two vehicles without involving other vehicles.

[0009] Currently, there is no networking or offline technique available for group leaders to delegate another vehicle as a platoon leader and to notify other member vehicles in the platoon of the change of the leader vehicle. In addition, in some cases, the lead vehicle can not be qualified to request another vehicle in the platoon as a lead vehicle. In this case, the VAE server decides to change the lead vehicle. Currently, there is no method available for the VAE server to network to change the group leader.

[0010] To support cooperative driving, vehicles in a platoon share messages with other vehicles that are not members of the platoon with group information (i.e., size, speed, spacing policy, their position in the group, planned trajectory, etc.). Other vehicles can receive the messages and identify acceptable groups based on certain criteria (i.e., speed and spacing policy, size). Vehicles can send a request to join a particular group, and the group leader can accept or reject the request to join the group.

[0011] Currently, there is no method available for non-member vehicles to request to join a particular group based on certain criteria, and there is no method available for the group leader to make a decision on the request of the non-member vehicles to join the group.

[0012] Therefore, there is a need for a solution that overcomes the above-mentioned drawbacks.

In an embodiment, the capability related to the V2X UE B can be determined based on a plurality of parameters. In an embodiment, the plurality of parameters can include a fuel amount, one or more sensors, and an application for communicating and coordinating with at least one other V2X UE in the group. In an embodiment, the capability associated with the V2X UE B indicates that the V2X UE B has the capability to lead the group.

[0069] Continuing with the above embodiment, the VAE client B can be configured to transmit, to the VAE server 112, a group information update consent response upon receiving the group information update consent request. In an embodiment, transmitting the group information update consent response can correspond to accepting the group information update consent request.
