  • Patent number: 11606825
    Abstract: A RAN node (2) receives, from a core network node (6, 7, 8), a first identifier that is used by a service, an application, or an edge server (5) to identify a radio terminal (1) connected to the RAN node (2), and associates the first identifier with a second identifier that is used by the RAN node (2) to identify the radio terminal (1). Further, the RAN node (2) communicates with the edge server (5) using the first identifier. It is thus, for example, possible to allow an MEC server (or an MEC application hosted on the MEC server) and a radio access network (RAN) node to directly exchange therebetween a control message regarding a specific radio terminal.

  • Patent number: 10512011
    Abstract: A control node (142) used in connection with a core network (120) operates to transmit a relocation command message related to a first network node (121S) located in the core network (120) and performing mobility management and bearer management of a plurality of mobile terminals (111) that have attached to the core network (120). The relocation command message causes relocation, from the first network node (121S) to at least one second network node (121T), of the mobility management and the bearer management for at least one of the plurality of mobile terminals (111). This contributes, for example, to relocation of mobility management and bearer management of a plurality of mobile terminals between network nodes regardless of the movement of those mobile terminals.
