There is provided a communication device capable of determining whether admission of new data traffic is allowed or rejected not by comparing throughputs only, but by considering other parameters when the data traffic is admitted. A communication device () according to the present invention includes a determination unit () that determines whether to admit a flow regarding a new radio terminal (), the flow being to be transmitted between a radio terminal () and a base station () and having a transmission deadline, depending on a transmission state of a plurality of data packets included in the flow, and a communication unit () that transmits, to the base station (), instruction information indicating whether to admit the flow regarding the new radio terminal ().

An object is to provide a communication apparatus which can perform efficient scheduling for finishing data transmission of a plurality of UEs within a permitted delay time. A communication apparatus () according to the present invention includes: a selecting unit () configured to select a wireless terminal () which is an allocation target of radio resources according to a time to a transmission deadline of a flow related to each of the wireless terminals (); an allocating unit () configured to determine radio resources allocated to the selected wireless terminal () so as to maximize use efficiency of the radio resources included in a control cycle including a plurality of unit times; and a communication unit () configured to transmit information related to the determined radio resource to a base station () configured to perform wireless communication with the selected wireless terminal ().

A network entity () sends, to a mobility management entity () or a subscriber server (), a request message in order to configure the mobility management entity () to report a second identifier to be used by a radio access network node () for identifying a radio terminal (). Further, the network entity () receives the second identifier from the mobility management entity () directly or through the subscriber server () and communicates with the radio access network node () 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.
