Example method, apparatus, and computer program product embodiments are disclosed to enable out-of-band short-range communication carrier transport switching for connection setup of in-band device-to-device communication. Example embodiments of the invention include a method comprising the steps of transmitting, by a first device via an out-of-band short-range communication carrier, an indication to a second device that a carrier switch from the out-of-band short-range communication carrier to an in-band short-range communication carrier is desired; receiving in response to the transmitted indication, a response from the second device via the out-of-band short-range communication carrier including an indication that the carrier switch from the out-of-band short-range communication carrier to the in-band short-range communication carrier is confirmed; and modifying, by the first device, device detection procedure associated with the in-band short-range communication carrier to improve detection of paging signals on the in-band short-range communication carrier.
