Abstract: An object of the present invention is to provide a vehicle communication system which distributes information which is necessary in vehicle units. A vehicle communication system according to the present invention includes: a vehicle base station which performs wireless communication with a vehicle terminal installed in a vehicle to receive vehicle related service; and a server apparatus which specifies the vehicle base station of a message distribution destination according to the vehicle related service to be provided, and distributes a message related to the vehicle related service to be provided, to the specified vehicle base station. When receiving the message transmitted from the server apparatus, the vehicle base station transmits the message to the vehicle terminal which subscribes to the vehicle related service related to the message, from a plurality of vehicle terminals and located in a communication area formed by the vehicle base station.

Abstract: A RAN node (2) receives, from a core network node (6, 7, 8), a first identifier that is used by a service, an application, or an edge server (5) to identify a radio terminal (1) connected to the RAN node (2), and associates the first identifier with a second identifier that is used by the RAN node (2) to identify the radio terminal (1). Further, the RAN node (2) communicates with the edge server (5) using the first identifier. It is thus, for example, possible to allow an MEC server (or an MEC application hosted on the MEC server) and a radio access network (RAN) node to directly exchange therebetween a control message regarding a specific radio terminal.

Abstract: A communication system capable of dynamically changing an MME to serve in call processing in accordance with the load condition of the MMEs and the like is provided. A communication system of the present invention includes: communication control apparatuses (10) to (12); and a node apparatus (20) that executes call processing relating to a communication terminal with the communication control apparatuses (10) to (12). The communication control apparatuses (10) to (12) form a context sharing group that shares subscriber data of the communication terminal. The node apparatus (20) selects a first communication control apparatus in the context sharing group, and transmits a call processing message to the first communication control apparatus. The first communication control apparatus executes the call processing using the subscriber data shared in the context sharing group.
