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: An external node (5) receives a transmission history (1301) regarding a first communication event of a first radio terminal (1) from a node (2) located in a radio access network (3). The external node (5) transmits to the node (2) a control request (1302) to control at least one of: a communication module (521) disposed in the node (2) for communicating with the external node (5); a scheduler (503, 903) disposed in the node (2); a data buffer (502, 11) disposed in the node (2) or the first radio terminal (1); and the first radio terminal (1). It is thus, for example, possible to contribute to an improvement for adapting packet scheduling to communication performed by an application of a radio terminal.

Abstract: An external node (5) determines a total size of a plurality of data packets to be transmitted in a first communication event of a first radio terminal (1) and a transmission deadline for the plurality of data packets. The external node (5) transmits the determined total size and transmission deadline to a node (2) in a radio access network (3) (201). It is thus, for example, possible to contribute to an improvement for adapting packet scheduling to communication performed by an application of a radio terminal.
