Claim Text:
1. A method for performing single radio handover, the method comprising: establishing a source radio link between a source radio interface of a mobile node and a source network in accordance with a first communications protocol, wherein the source radio interface includes a source transmitter and a source receiver that are configured to communicate in accordance with the first communications protocol when activated; activating, by the mobile node, a target receiver in a target radio interface of the mobile node without activating a target transmitter in the target radio interface of the mobile node, wherein the target receiver and the target transmitter are configured to communicate in accordance with a second communications protocol when activated; discovering, by the mobile node, a target network by detecting a target network transmission using the activated target receiver, wherein the target transmitter remains deactivated until after the target network transmission is detected by the activated target receiver; communicating handover signaling to a target access point in the target network, the handover signaling specifying a delay period for handing the mobile node from the source network to the target network, wherein the target transmitter remains inactive when communicating the handover signaling to the target access point; terminating the source radio link upon expiration of the delay period; and activating, by the mobile node, the target transmitter of the target radio interface after terminating the source radio link.
