摘要： Systems and methods are provided for managing communications between two or more ad-hoc networks in a communication system. The systems and methods may have flexible communication time sharing of one or more nodes taking part in two or more ad-hoc networks. For example, the communication scheduling function for a node shared by two or more ad-hoc networks is provided with a generic functional architecture such that it may be located in a number of different locations. In one embodiment, a Bluetooth communication system includes an inter-piconet scheduling function having a JUMP mode introduced to distinctly identify a node to its neighbors as being shared with multiple ad-hoc networks. The jump mode may have one or more methods for managing the inter-network communications that may include: (1) predetermined fixed starting point and length communication windows, (2) time points with flexible starting points and communication window length, and/or (3) random starting time and length communication windows.

摘要： Apparatus and methods for providing Rendezvous point Interpiconet Scheduling (RIPS) in an ad hoc polling based communication infrastructure such as a Bluetooth system in which a PMP node (Participant in Multiple Piconet nodes) belongs to more than one piconet. The rendezvous (RV) points of a PMP node is defined based on information specific to the node, rather than being associated with the links between slave and master nodes. By defining RV points per PMP node rather than per link, the master node of a piconet in the RIPS system is aware of the RV points that its slave PMP nodes have in other piconets. This advantageously allows a master node in the RIPS system to know when its slave nodes will be present in the piconet and when they will not be present.

摘要： A method and apparatus for improving channel utilization and throughput in an ad-hoc wireless communication system is provided. A master unit and one or more slave units are coupled to a shared communication channel having at least an uplink (UL) channel and a downlink channel (DL) for each master unit-slave unit pair. A group of active nodes is established corresponding to slave units having UL and/or DL data associated therewith for transfer. The group of active nodes may be polled according to Fair Exhaustive Polling (FEP) and information alternately transferred on a TDD. Accumulated information may be transferred in a batch and feedback information collected and used to adjust polling. One or more links may be identified as lossy links due to increased Bit Error Rate (BER) and accompanying information loss resulting in lower throughput. Virtual active nodes added to the group of active nodes to compensate therefor. A transmission parameter such as number of retransmissions may be evaluated against a predetermined threshold to identify lossy links. If lossy links improve, virtual active nodes may be removed from the group of active nodes. Information associated with the one or more slaves units may be circuit switched synchronous information or non-circuit switched asynchronous information. Feedback information such as timeout information associated with the slave units may be evaluated. If a time out signal associated with a slave unite is received the slave unit may be scheduled for polling responsive to the time out signal.

An example method includes generating (810) an assisting security key for the assisting base station, based on an anchor base station key.
