A communication terminal comprising: a timing detection unit configured to detect arrival of timing according to a configured cycle; a condition determination unit configured to determine whether or not a shared condition shared with a base station is satisfied; a receiving unit (220, 232) configured to receive paging instruction information related to the shared condition; and a communication controller configured to control reception of paging when the timing detection unit detects the arrival of timing and the condition determination unit determines that the shared condition is satisfied in a situation where the paging instruction information includes flag information indicating extension of a paging cycle; wherein the configured cycle corresponds to a first discontinuous reception cycle assigned individually to the communication terminal or a second discontinuous reception cycle common in a cell, both the first discontinuous reception cycle and the second discontinuous reception cycle being shorter than a cycle of system frames; wherein the communication controller is configured to control reception of paging in accordance with a first processing cycle for paging when the timing detection unit detects the arrival of timing and the condition determination unit determines the shared condition is satisfied, the first processing cycle for paging being longer than the cycle of system frames, and being determined based on the first discontinuous reception cycle or the second discontinuous reception cycle, and an extension parameter included in the paging instruction information; and wherein the communication controller is further configured to control reception of paging in accordance with a second processing cycle for paging determined based on the first discontinuous reception cycle or the second discontinuous reception cycle in a situation where the paging instruction information does not include flag information indicating extension of a paging cycle, the second processing cycle for paging being shorter than the cycle of system frames. a timing detection unit configured to detect arrival of timing according to a configured cycle; a condition determination unit configured to determine whether or not a shared condition shared with a base station is satisfied; a receiving unit (220, 232) configured to receive paging instruction information related to the shared condition; and a communication controller configured to control reception of paging when the timing detection unit detects the arrival of timing and the condition determination unit determines that the shared condition is satisfied in a situation where the paging instruction information includes flag information indicating extension of a paging cycle; wherein the configured cycle corresponds to a first discontinuous reception cycle assigned individually to the communication terminal or a second discontinuous reception cycle common in a cell, both the first discontinuous reception cycle and the second discontinuous reception cycle being shorter than a cycle of system frames; wherein the communication controller is configured to control reception of paging in accordance with a first processing cycle for paging when the timing detection unit detects the arrival of timing and the condition determination unit determines the shared condition is satisfied, the first processing cycle for paging being longer than the cycle of system frames, and being determined based on the first discontinuous reception cycle or the second discontinuous reception cycle, and an extension parameter included in the paging instruction information; and wherein the communication controller is further configured to control reception of paging in accordance with a second processing cycle for paging determined based on the first discontinuous reception cycle or the second discontinuous reception cycle in a situation where the paging instruction information does not include flag information indicating extension of a paging cycle, the second processing cycle for paging being shorter than the cycle of system frames.
