Patent number: 11116029Abstract: 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.Type: GrantFiled: July 31, 2017Date of Patent: September 7, 2021Assignee: NEC CORPORATIONInventors: Takanori Iwai, Nobuhiko Itoh, Ling Xu, Kenki Takagi, Toshiyuki Tamura, Tomoaki Hokao, Naoaki Suzuki, Hisashi Futaki, Sadafuku Hayashi, Kazuki Eguchi, Kouichi Kimura, Hiroki Aoki, Hideki Bessho, Yoshinori Watanabe, Tooru Kikuchi
