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) 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.

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: A communication system, which is preventing recognition inconsistency with respect to a buffer size of user equipment between the user equipment and a base station, includes the user equipment and a base station. The user equipment buffers uplink data. The user equipment transmits, in an uplink, a buffer status report for identifying an amount of the uplink data buffered. The base station transmits, in a downlink, grant information for allocating a radio resource to the user equipment. The user equipment transmits, based on the amount of the buffered uplink data, the buffer status report for stopping of transmission of the grant information by the base station. The base station receives the buffer status report and stops the transmission of the grant information, based on the received buffer status report.
