Title: Method of managing an assignment of cids in a aal2 node
Inventor: KIM DUCK JUNG
IPC: H04L29/02
Filed: 2007-11-29
Abstract: A method of managing cid assignment of an AAL2 node is provided to assign a CID of one group among divided CIDs according to whether an AAL2 node has an ownership about a virtual channel, thereby reducing possibility of CID collision. An AAL2 node receives a new communication access request(102). The AAL2 node sets an allocation pointer in a location that a header of a non-allocated CID list indicates(104). The AAL2 node determines whether a node has an ownership of a virtual route(106). If the node has the ownership, the AAL2 node determines whether a CID number located in the allocation pointer is a value smaller than 131(108). If the CID number is smaller than 131, the AAL2 node assigns CID to communication access(110). A list element is moved to a previously allocated CID list and the allocation pointer is canceled(112).

Title: Method of connecting a new device to an existing network
Inventor: HABETHA JOERG
IPC: H04L12/28
Filed: 2005-07-11
Abstract: In a centralized radio network consisting of several devices one device acts as master or network coordinator and has a transmission range. Basically, other devices of the network are able to adopt the role of a coordinator. This ability is used to enlarge the area of the network to a size larger than the transmission range of the master. A device asks its parent PNC to become a child PNC when a newly turned on device acts as a temporary PNC and broadcasts an initiation beacon indicating that it looks for a child PNC. The child PNC reports that it is available. The new device determines one of the available child PNCs to be its new master. The acknowledgment for the selected child PNC may be broadcasted to inform all the devices in the transmission range of the new device. The new device quits the role of the temporary PNC and associates to the existing network.
