Abstract: A method for real-time and dynamic event-related information derivation and dissemination by a road infrastructure to control, coordinate and consolidate information from one or more observation entities includes receiving, by a road infrastructure server of the road infrastructure, event information from the observation entities. Each of the observation entities provides its event information as an event information frame that comprises an event data record including a number of attributes together with a unique identifier referencing the event data record. The event information frames received from the observation entities are collected and analyzed, and are processed to generate a combined event information frame that includes composite event information, a unique identifier referencing the composite event information, and control commands to coordinate communication with the observation entities. The combined event information frame is distributed within a distribution domain.

Abstract: An access GW (201) receives, from a mobility management node (300), a transmission-path control signal for changing a route of only part of a data packet flow that pertains to a mobile terminal (400) and is originally relayed through the access GW (201) and a first mobility anchor (100A). In response to receiving the transmission-path control signal, the access GW (201) establishes a logical transmission path with a second mobility anchor (100B) for transferring the part of the data packet flow, and transfers the part of the packet flow to the second mobility anchor (100B) and also transfers a remaining part of the packet flow to the first mobility anchor (100A) by distinguishing a data packet received from the mobile terminal (400). As a result, for example, a mobility anchor can be switched for a part of data packets relating to the mobile terminal (400) under the initiative of the mobility management node (300).
