1. A method of receiving a paging message by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving the paging message that includes task information in a task field from a base station (BS);
performing a task according to the task information; and
performing a procedure for a state transition according to the task information,wherein the task information is at least an initialization of a machine type communication (MTC) function or an interruption of the MTC function,wherein the paging message further includes a group identifier (ID) of the UE that identifies a group to which the user equipment belongs,wherein the paging message is received in a paging occasion (PO) that is a sub-frame, the PO based obtained on the group ID,wherein the sub-frame is read by calculating the PO based on an identity of the UE when the UE is in a radio resource control (RRC) idle state,wherein the PO is classified by an at least MTC specific PO, a group specific PO or a UE specific PO,wherein the MTC specific PO is used to receive the paging message only for MTC devices,wherein the group specific PO is calculated according to the group ID in order to receive the paging message only for a specific group,wherein the UE specific PO is calculated according to the identity of the UE in order to receive the paging message only for a specific UE, andwherein the group ID is obtained when the user equipment receives signaling from the BS.

4. A method of transmitting a paging message by a base station in a wireless communication system, the method comprising
transmitting the paging message that includes task information in a task filed to at least one user equipment (UE); - and
performing a procedure for a state transition according to the task information, wherein the task information is at least an initialization of a machine type communication (MTC) function or an interruption of the MTC function, wherein the paging message further includes a group identifier (ID) of the at least one UE that identifies a group to which the at least one UE belongs, wherein the paging message is transmitted in a paging occasion (PO) that is a sub-frame , the PO obtained based on the group ID, wherein the sub-frame is read by calculating the PO based on an identity of the UE when the UE is in a radio resource control (RRC) idle state, wherein the PO is classified by at least an MTC specific PO, a group specific PO or a UE specific PO, wherein the MTC specific PO is used to receive the paging message only for MTC devices, wherein the group specific PO is calculated according to the group ID in order to receive the paging message only for a specific group, wherein the UE specific PO is calculated according to the identity of the UE in order to receive the paging message only for a specific UE, and wherein the group ID is signaled to the at least one UE. - View Dependent Claims (5, 6)
