  • Publication number: 20200359433
    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.

  • Publication number: 20180139691
    Abstract: An exemplary object is to provide a communication system capable of seamlessly providing a service with utilization of MEC even when a communication terminal has moved across a wireless LAN communication area in a mobile communication area formed by a base station. The communication system according to the present invention includes a base station (10) that forms a mobile communication area, an access point (20) that forms a wireless LAN communication area, and an application server (40) that provides application services to a communication terminal (50) located in the mobile communication area. When the communication terminal (50) has moved into the wireless LAN communication area in the mobile communication area, the access point (20) sets a data transmission path with the base station (10) and relays data transmission between the base station (10) and the communication terminal (50).
