Methods and communicators for transferring a soft identity reference from a first vehicle to a second vehicle in a platoon

摘要

Methods (400, 600) and communicators (210, 220) in a first vehicle (110-1) and a second vehicle (110-2) respectively, in a platoon (100), for transferring a soft identity reference, associated with the first vehicle (110-1) when acting as a gateway in the platoon (100), to the second vehicle (110-2), enabling the second vehicle (110-2) to start acting as gateway in the platoon (100). The method (400) comprises: determining (402) to transfer the soft identity reference to the second vehicle (110-2); transmitting (403) a message to a communication network node (130) that the first vehicle (110-1) is going to discontinue acting as gateway; transmitting (404) a message to a connectivity node (120) for inactivating the soft identity reference associated with the first vehicle (110-1); and transferring (405) the soft identity reference to the determined (402) second vehicle (110-2).
