Abstract
A method and apparatus for monitoring paging in a mobile communication system are provided. Method for monitoring paging includes receiving a first message including first paging cycle and second paging cycle from the AMF, receiving a second message including third paging cycle and fourth paging cycle from the base station, receiving a system information including an information related to the support of extended DRX, determining a reference DRX cycle, monitoring paging occasion based on the reference DRX cycle and receiving a short message.
Claims13
A method by a base station in a wireless communication system, the method comprising:
- receiving from an Access Mobility Function (AMF) a first message comprising a parameter for an extended discontinuous reception (DRX) cycle;
- receiving from a base station a system information block1 (SIB1), wherein the SIB1 comprises:
- a parameter for modification period;
- and
- a parameter indicating extended DRX is allowed;
- determining a paging frame based on the extended DRX cycle;
- monitoring a paging occasion in the paging frame;
- and
- receiving from the base station a second message,
- wherein the second message comprises:
- a first bit related to system information modification;
- and
- a second bit related to system information modification,
- wherein a system information acquisition procedure is started at a first time point in case that:
- the first bit in the second message is set to 1;
- and
- the terminal does not operate with extended DRX cycle longer than a modification period, and
- wherein the system information acquisition procedure is started at a second time point in case that:
- the second bit in the second message is set to 1;
- and
- the terminal operates with extended DRX cycle longer than the modification period.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to control the transceiver to:
- receive from an Access Mobility Function (AMF) a first message comprising a parameter for an extended discontinuous reception (DRX) cycle,
- receive from a base station a system information block1 (SIB1), wherein the SIB1 comprises:
- a parameter for modification period;
- and
- a parameter indicating extended DRX is allowed,
- determine a paging frame based on the extended DRX cycle,
- monitor a paging occasion in the paging frame, and
- receive from the base station a second message,
- wherein the second message comprises:
- a first bit related to system information modification;
- and
- a second bit related to system information modification,
- wherein a system information acquisition procedure is started at a first time point in case that:
- the first bit in the second message is set to 1;
- and
- the terminal does not operate with extended DRX cycle longer than a modification period, and
- wherein the system information acquisition procedure is started at a second time point in case that:
- the second bit in the second message is set to 1;
- and
- the terminal operates with extended DRX cycle longer than the modification period.
