Abstract: Data packets are transmitted from a first access network to a first interface of a multiple interface device (MID), and identical data packets are transmitted concurrently from a second access network to a second interface of the MID. Some of the data packets that are transmitted to the MID from the first access network are not received by the first interface. The MID inspects identifiers of data packets from the first and second interfaces in order to send to the application a stream including all of the data packets. For example, the MID sends to the application the data packets from the first interface, buffers the data packets from the second interface, and sends data packets from the buffer to the application upon detecting that data packets in the buffer were transmitted to the first interface but not received by the first interface.

Abstract: An arrangement including a scannable matrix for predicting the occurrence of a future collision of frequency hops of the channel hopping patterns on the respective activated first paths of a Bluetooth packet transmission system is described. A first coordinate of the matrix defines columns representative of a selectable window of N successive future time slots of the channel hopping patterns, and a second coordinate of the matrix defines rows each exhibiting the successive frequency hops of the patterns segments transmitted on a separate one of the activated channels during such window. The first coordinate is scanned to detect the occurrence, if any, of identical frequency hops appearing at an intersection of the then-scanned column and at least a pair of the rows.

In some embodiments, the system includes: an access point having a variable beamformer configured to fluctuate signal strength as perceived by stations within a range of the access point; and a plurality of stations having modified distributed-MAC protocol such as to be channel-aware and opportunistic.

Abstract: A Virtual Soft-Hand-off method for wireless IP-centric CDMA networks whose routers, hosts, and mobile stations have small group multicast (SGM) capability comprises setting up an explicit synchronous multicast session among a small group of participants with dynamic group membership. Packets transmitted over the multicast session are time stamped to help maintain synchronization, and the receivers recover multiple packet flows from the multiple received signals concurrently and combine them to create a single packet flow at higher layers.

Abstract: An efficient method and apparatus for rapidly and flexibly setting, on a remote basis, the value of a selected IP parameter(s) in each of a plurality of networked computing devices within a local proximity to support transmission using the IP protocol. In an illustrative embodiment wherein each device is connectable to a common backbone network, each device is also provided with an interface that supports radio transmission using Bluetooth protocols. The desired setting of the selected IP parameter for each device is implemented by means of a prescribed sequence of suitable Bluetooth messages transmitted by a common remote Bluetooth terminal.

Abstract: A method and system is provided for periodically and dynamically updating allocation pools of IP address which are reserved for wireless or wireline hosts. A system IP address server controls an entire address pool, contains predictive analysis logic, performs a predictive analysis, partitions the IP addresses into distinct address pools, and maintains “wireless guard bands” of IP addresses for wireless users to ensure that a higher priority address pool is never exhausted before an address pool which has a lower priority.

Abstract: Methods for coordinating power usage and link adaptation in wireless communications are described. Terminals and/or access points (APs) may attempt to modify terminals' transmit power in relation to a desired communication data transfer rate. Link adoption may also be used in conjunction with the described methods.

Abstract: A Bluetooth-enabled terminal having a radio manager for minimizing frequency collisions between channel hopping patterns transmitted over plural channels established between such terminal and correspondent Bluetooth devices is described. The radio manager extracts successive sets of projected future N—time slot segments of the respective Bluetooth channel hopping patterns. Each extracted set is tested to detect a time slot, if any, where frequency hops of the segments of the set coincide, indicating a frequency collision. When a collision time slot is detected, the radio manager generates a marker which triggers an alteration of the frequency hops that would otherwise be exhibited by a subset of the generated channel hopping patterns in such detected time slot. Such terminal may optionally be provided with an additional network interface to define a collision-resistant Bluetooth access point.

Abstract: Method for selecting IP data packet segments in an all-IP architecture that supports CDMA soft handoff via IP multicasting, wherein both the mobile terminal and IP backbone network receive a plurality of identical, redundant CDMA IP data packets. A best IP data packet is created by first, receiving a plurality of IP data packets from a plurality of corresponding base stations, second, separating those IP data packets into data packet segments comprising separate time intervals, and third, employing different metric standards to determine which of those data packet segments received for each time interval is the best data packet segment. The best data packet segments are determined by creating a quality matrix that represents the quality of each data packet segment for each time interval. A quality function is then computed for each time interval to determine which data segment is the best for that particular time interval.

Abstract: A system and method for equalizing traffic between antenna beams is described. Aspects of the system and method may vary the beam widths to attempt to equalize traffic based on non-real-time communications and/or non-real-time communications.

Abstract: In a network of devices having a plurality of local domains, each local domain is likely to comprise a plurality of networks or communities of devices that communicate using a shared native protocol such as Jini, UPnP, Bluetooth, HAVi, WiFi, WiMAX or other standard architectures and protocols. The Open Services Gateway initiative (OSGi) created a platform and method for various networks to communicate with one another in a local domain. OSGi does not, however, solve the problems associated with communication across local domains. An instant messaging protocol such as Session Initiation Protocol (SIP) and a remote services register are used to provide a means for communication between local devices in a plurality of local OSGi domains using native communications protocols.

The system determines the angle of arrival of the packet transmissions and forms a select beam to cover at least one of the stations.

Abstract: Entity identity information and location identity information are sensed and made available to subscriber applications through a secure location-aware services infrastructure, thereby allowing for the creation of location-based services. Information detected by a sensor is passed to an interface aggregator for conversion to a standardized format and then forwarded to location registers for the domain of the sensors. Subscriber applications query the registers to determine which entities are in a particular location and to determine the location of entities. By unifying diverse sensing technologies, location information can be simultaneously obtained on varying degrees of granularity. In addition, the system is scalable to large scenarios by using a plurality of sensors, interface aggregators, and registers.

Abstract: A system and method for assigning channel access is described. At least one of a terminal or an access point transmits a message to other entities where the message assigns access to an assignee and includes a duration field of a specified length. The unassigned terminals or access point remain silent for a duration specified in the duration field while the assignee has access to the channel.

Abstract: A system and method for aggregating and fragmenting packets is described. Data packets containing voice data and other data that suffer significantly in quality when delayed may be aggregated together and fragmented. The aggregation and fragmentation permits networks to push these time-sensitive packets more easily through a network based on priority given to fragmented data.

Abstract: A method and system for soft handoff of a mobile terminal in a wireless CDMA IP network utilizes IP multicasting to a plurality of multicast participants that reside at the mobile terminal. A soft handoff multicast protocol is used to assign a unique IP multicasting address to the mobile terminal and establish a plurality of multicast participants that reside at the mobile terminal, thereby creating corresponding multicast network connections between the IP network and the mobile terminal. The IP network simultaneously transmits information to the mobile terminal via the multicast network connections by broadcasting the information as a multicast message to the mobile terminal's multicast group. The multicast extends between a mobile terminal and a plurality of a base station associated with the network to simultaneously communicate information over separate communication channels.

Abstract: Method and apparatus for dynamically allocating IP addresses in a wireless IP network. IP address servers determine the requisite IP address pools and guard bands for individual network cells to guarantee fair access to the network and facilitate handoff host handoff from a prior cell to a new cell. IP address servers also prioritize handoff and resident hosts that request an IP address from the IP address server. In particular, IP address servers assign a higher priority to handoff hosts over resident hosts that request an IP address from an IP address server in order to maintain a preestablished handoff host network connection instead of dropping a handoff host connection in favor of a new resident host network connection. Finally, each cell is allocated a minimum number of IP addresses to ensure a certain level of fair access to the network regardless of the cell wherein a handoff or resident host resides.
