Abstract:
1. A method for operating in an idle mode for Machine To Machine (M2M) communication, comprising: entering, by a M2M device, into an idle mode; receiving, by the M2M device in the idle mode, a paging message from a base station, the paging message including a network access type and a resource offset, the network access type indicating a resource allocation for a ranging request, the resource offset indicating an offset that the M2M device starts to monitor assignment information; and monitoring, by the M2M device, the assignment information beginning from the offset, wherein the assignment information includes an identifier type and a second part of the M2M identifier, wherein the identifier type indicates that the M2M identifier is a fixed M2M deregistration identifier (FMDID) or a deregistration identifier (DID), the FMDID being a 16-bit identifier that uniquely identifies the M2M device in domain of the base station, the DID being an 18-bit identifier that uniquely identifies the M2M device in domain of a paging group, and wherein when the identifier type indicates that the M2M identifier is the FMDID, the first part of the M2M identifier includes least significant bit (LSB) 12 bits of the FMDID and the second part of the M2M identifier includes most significant bit (MSB) 4 bits of the FMDID.
