Abstract: A network entity (5) sends, to a mobility management entity (6) or a subscriber server (9), a request message in order to configure the mobility management entity (6) to report a second identifier to be used by a radio access network node (2) for identifying a radio terminal (1). Further, the network entity (5) receives the second identifier from the mobility management entity (6) directly or through the subscriber server (9) and communicates with the radio access network node (2) by using the second identifier. It is thus, for example, possible to allow an MEC server (or an MEC application hosted on the MEC server) and the radio access network (RAN) node to directly exchange therebetween control messages regarding a specific radio terminal.

Abstract: In order to enable the protection of a system in which an abnormality is detected even while restricting the degradation of availability of a service provided by a base station device, a communication system in an exemplary embodiment has a first server which provides a first service, a second server which provides a second service, and a first base station device communicating with the first and second servers, wherein in the case where the second service has a higher priority than the first service, a communication path between the first base station device and the first server is cut off when an abnormality is detected from the first server.
