    摘要: A method of reducing an audio gap in a signal connection with a communication unit during handoff in a cellular communication system is provided. The method includes the steps of providing a temporary signal connection with the communication unit from a mobile switching center (MSC) of a source base site, through the source base site to a handoff target base site and establishing a trunk connection from the MSC of the source base site to a MSC of the target base site. The method further includes the step of interconnecting, at the target base site, the temporary signal connection, trunk connection, and communication unit; and re-routing the signal connection with the communication unit through the trunk connection.

    摘要: A method is offered of achieving a desired C/I ratio within a cellular system, at reduced transmitter power levels, by measuring a signal loss on a downlink between a base site transmitter (31) and mobile receiver (20) and calculating an uplink signal magnitude at a base site receiver. A communication channel is then selected from a number of communication channels based upon comparison of the uplink signal magnitude with pre-measured interference levels for each channel of the number of channels to produce a desired C/I ratio.

    摘要: A method and apparatus for channel assignment within an ad-hoc communication system utilizing multiple channels is provided herein. Individual nodes receive and send route-request (RREQ) packets on all channels rather than a single channel. Each route-request packet comprises a first and a second table. The first table comprises a channel state for the link and the second table comprises a channel quality metric for the link. Each node updates the channel state and channel quality tables and forwards them in the RREQ packet as part of the route-discovery process. When channel selection is made, the channel selection is based on the channel state and the channel quality tables.

    摘要: A network reconfiguration protocol is provided that is initiated by the congested communication node (300). When a node (300) determines it is a bottleneck node, it will then analyze complaints from other nodes to determine which nodes are being affected by the bottleneck. The congested node will request the reconfiguration of select neighboring communication nodes in the ad hoc network to use an alternate channel (e.g., frequency) for future communications. Because nodes experiencing poor transmission/reception due to a bottleneck node are reconfigured to operate on a different channel, congestion is greatly reduced.

    摘要: A method and system for positioning a relay in a wide area communication network can enable improved operating efficiency of the network. The method includes processing a plurality of requests, received from a plurality of wireless communication devices, for connections to the network, where each device in the plurality of wireless communication devices can operate using a wide area networking standard and can operate using an ad hoc networking standard (step 305). A location in the network of each device in the plurality of wireless communication devices is then determined (step 310). An operating position for the relay is then determined based on an evaluation of the location in the network of each device in the plurality of wireless communication devices (step 315).

    摘要: A method and apparatus for synchronizing a node (200) within an ad-hoc communication system (100) is described herein. During operation all nodes periodically broadcast a synchronization beacon for other nodes to utilize for synchronization when a coordinating access point (node) is unavailable. A particular node's synchronization beacon will have an associated “tier” number that is incremented from the tier number of the beacon used to synchronize the particular node. In the absence of an access point, a node that joins the ad-hoc communication system will listen for synchronization beacons transmitted by other nodes. If synchronization beacons are heard, the node will synchronize with a beacon having a lowest tier. The node will then broadcast its own beacon having its tier number incremented from the lowest tier beacon heard.
