Abstract
A method and apparatus are therefore provided that may enable the provision of M2M communication in a wireless network environment. In this regard, for example, relatively low power devices (specifically referencing low transmission power) such as sensors or other machines in an M2M system may be enabled to initiate communication with a network through a mobile terminal in a more reliable and robust manner. The machine may transmit a busy-signal to request a reservation of a machine access slot on a machine access control channel to reserve the slot before transmitting any machine information or data to reduce the likelihood of collisions with other machines. Once the machine has reserved the machine access slot, the machine may transmit identification information via randomly selected frequency division multi-plexed or code division multiplexed resources to further reduce the likelihood of collisions with other machines. Thus, delays in establishing connections may be reduced or eliminated.

34. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least perform:
-
determine if a busy-signal has been detected for a machine access slot of a machine access channel; provide for transmission of a busy-signal request for a reservation of the machine access slot in response to determining that no busy-signal had been detected for the machine access slot; provide for transmission of identification; and receive a machine access response message. - View Dependent Claims (35, 36, 37, 38, 39, 40)

41. A method comprising:
-
determining if a busy-signal has been detected for a machine access slot of a machine access channel; providing for transmission of a busy-signal request for reservation of the machine access slot in response to determining that no busy-signal had been detected for the machine access slot; providing for transmission of identification; and receiving a machine access response message. - View Dependent Claims (42, 43, 44, 45, 46, 47)

48. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least perform:
-
receive a machine identification over a reserved machine access slot in a machine access channel; blindly decode the machine access channel to obtain the machine identification; provide for transmission of the machine identification; and receive a machine access response message. - View Dependent Claims (49, 50, 51)
