Abstract: A radio communication network includes: a control plane (C-plane) node (24) located in a core network (20); a local gateway (14) located in a Radio Access Network (RAN) (10) including a base station (11). The C-plane node (24) has a C-plane of a PDN gateway and provides a first C-plane interface for communicating with a PCC entity relating to Policy and Charging Control (PCC). The local gateway (14) has a user plane of a PDN gateway and provides IP connectivity to the base station (11) to offload a particular type of traffic. The local gateway (14) further provides a second control plane interface for communicating with the C-plane node (24).

Abstract: An approach for network information collection and analysis of a plurality of mobile networks is provided. The approach receives a first request message including a first threshold sent from an application server. The approach sends a second request message to at least one network function. The approach receives a congestion report from the at least one network function which monitors for a change in a congestion status related to a base station that is crossing a second threshold. The approach derives a network information by combining the congestion report. The approach sends the network information to the application server, the first threshold indicating a range of the network information at which the application server wishes to be informed of the network information.

Abstract: A radio terminal establishes a control connection with a network, and receives, from the network, a selection policy used for selection of a core network entity that provides a mobility management service or a data transmission service for the radio terminal. Further, the radio terminal selects a target core network entity based on the selection policy, and transmits, to the network, a request message for requesting provision of the mobility management service or the data transmission service by the target core network entity.

Abstract: A control apparatus (151) selects a target core network entity for providing a mobility management service or a data transfer service to a radio terminal (111), from among a plurality of candidate core network entities (121, 141, 142) having different route costs to the radio terminal (111) or having different sizes of a management range, based on at least one of: a delay tolerance level of the radio terminal (111); a frequency of occurrence of control signaling of the radio terminal (111); and a communication interval of the radio terminal (111). This contributes, for example, to determining which of a plurality of core network entities is used for a radio terminal by using one or more criteria (indices or parameters) other than the mobility of the radio terminal.

Abstract: A mobility management entity (121) receives, via a network entity (123, 122) in a core network (120), from an MTC service platform (130) that provides an application programming interface (API) for a Machine Type Communication (MTC) application server (132). The mobility management entity (121) performs control updating of at least one of (a) an RRC inactivity timer value applied to an MTC device (111), (b) a DRX inactivity timer value applied to the MTC device (111), and (c) a NAS backoff timer value applied to the MTC device (111).

Abstract: A first entity (123) in a core network (111) receives a first message (S101) indicating a mobility characteristic of a Machine Type Communication (MTC) device (111) from an MTC service platform (130) that provides an application programming interface (API) for an MTC application server (132). A second entity (121 or 122) in the core network (111) updates, based on the mobility characteristics received from the MTC service platform (131), at least one of the length of a periodic location update timer and the size of a paging area which are separately applied to the MTC device (111).

Abstract: A first network node (121S) is configured to perform mobility management and bearer management of a plurality of mobile terminals (111) having attached to the core network (120). Further, the first network node (121S) is configured to perform a relocation procedure for relocating the mobility management and the bearer management of the plurality of mobile terminals (111) to a second network node (121T) in the core network (120) in accordance with a relocation command from a control node (142) coupled to the core network (120). 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.
