Abstract
A base station includes a control unit that controls radio access network (RAN) paging processing for a terminal in a radio resource control inactive (RRC_INACTIVE) state and a transmitting unit that transmits, to any other base station connected by a given interface, RAN paging information elements including configuration information for extended discontinuous reception (eDRX) in the RAN paging processing for the terminal.
Claims4
A terminal comprising:
- a memory storing a program;
- and
- at least one processor that, by executing the program stored in the memory, is configured to:
- receive, from a base station, a Radio Resource Control (RRC) message including configuration information for an extended discontinuous reception (eDRX), the configuration information including information for indicating an eDRX cycle in hyper frames and information for indicating a length of a paging time window, the eDRX cycle being longer than 10.24 seconds;
- calculate a start position of the paging time window in a paging hyper-frame(PH) of a hyper-system frame number (H-SFN) based on the eDRX cycle and a hashed user equipment identity (UE_ID_H);
- and
- calculate an end position of the paging time window in the PH of the H-SFN based on the start position and the length.
