  • Publication number: 20120008627
    Abstract: One exemplary embodiment of the invention provides an apparatus to assign device identifier with collision avoidance in a distributed network environment. The apparatus may operate, for example, by using different control areas for different group of anchor DIDAFs, or the serving DIDAF/node may assign or cancel a set of available device IDs for an anchor DIDAF/node, so the anchor DIDAF/node may assign a device ID for a device in a control area of the serving DIDAF/node within the set of the available device IDs. In additions, the used and unused device ID assignment may be filtered by the serving DIDAF/node to allow or reject the device ID assignment or the serving DIDAF/node may translate the used device ID assigned by an anchor DIDAF/node to another unused device ID.
