Abstract: An apparatus, system and method for managing radio resources are disclosed. The apparatus for managing radio resources includes a media independent services (MIS) user unit, a link layer unit, and a media independent services function (MISF) unit. The link layer unit outputs its own link status and radio resource allocation status. The MISF unit receives a report on the link status and radio resource allocation status from the link layer unit, receives a report on link status of a terminal from the corresponding terminal, receives a report on link status and radio resource allocation status of a neighboring Point of Attachment (PoA) from the corresponding neighboring PoA, and receives network configuration information from a network configuration information server. The MIS user unit determines to change radio resource allocation based on information from any one of the link layer unit, the terminal, the neighboring PoA and the network configuration information server.

Abstract: The present invention relates to a method of providing proximity service communication between terminals. In accordance with an embodiment, a first terminal makes connection to a second terminal with network assistance. The first terminal requests information required to search for the second terminal from a network management server. The network management server determines a communication mode for proximity service communication. The network management server transmits a request message requesting communication between the first terminal and the second terminal in the communication mode to the first and second terminals. In accordance with another embodiment, a first terminal may switch its proximity service communication technology for better QoS without network assistance. The first terminal monitors link status. If the link status is deteriorated, the first terminal requests a second terminal to change proximity service communication technology. The first and the second terminal switch their proximity service communication technologies.

Abstract: Single radio handovers (SRHOs) between heterogonous networks can be facilitated using several techniques. One such technique includes activating a receiver of a target radio interface in a mobile node without activating a transmitter of the target radio interface, thereby allowing the mobile node to perform target network discovery while the transmitter of the target radio interface remains deactivated. Another such technique includes encapsulating link-layer discovery frames into media independent handover frames (MIH), and then tunneling the MIH frames over a tunnel extending through the source network. This may allow the MN to achieve various handover related tasks without activating the target radio link. Another technique includes establishing a schedule (or delay period) for synchronizing deactivation of the source radio interface with activation of the transmitter in the target radio interface.
