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: A traffic controller (8) receives, from a traffic monitor (7), a first control message generated in response to an increase in a total transmission rate of a plurality of packet flows sent from a plurality of wireless terminals (1) to a specific external network. The controller (8) determines, based on an evaluation criterion received from a criteria manager (6), one or more packet flows on which traffic shaping is to be imposed. In response to the first control message, the controller (8) controls a base station within a RAN (2) or a packet transfer node within a mobile backhaul (30) to execute the traffic shaping. This, for example, contribute to adjusting traffic that passes through a cellular communication network based on a monitoring result of a total transmission rate of traffic sent from the cellular communication network to the external network.

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.

Abstract: A network station sends a switching instruction to a mobile unit. The mobile unit has two receiving sections and a transmitting section operable in two data formats. Upon receipt of the switching instruction, the first receiving section switches from a first data format to a second data format. The transmitting section sends an acknowledgment signal to the network. The first receiving section and transmitting section then attempt to switch to the second data format. The second receiving section remains in the first data format. The first receiving section then attempts to achieve synchronization. If synchronization is successful, a completion notice is sent back to the network station and the second receiving section is switched from the first data format to the second data format.
