Abstract: An indoor location positioning system comprises at least one processor, Wi-Fi scanners, and a RSSI fingerprint database. The Wi-Fi scanners and the RSSI fingerprint database works with the processor. The Wi-Fi scanners are positioned at locations within an environment that is partitioned into interconnected zones. The Wi-Fi scanners receive anonymous probe messages from Wi-Fi devices that are present in the environment during a calibration phase of the indoor location positioning system. The RSSI values are collated to create RSSI fingerprints corresponding to the different locations respectively. One or more of the Wi-Fi scanners are used as anchor scanners to counter the difference in transmit power levels of different Wi-Fi devices that result in different RSSI fingerprints for the different types of Wi-Fi devices, wherein the RSSI value at each anchor scanner is subtracted from the RSSI values at rest of the Wi-Fi scanners to generate the RSSI fingerprint.

Abstract: An approach is provided for communicating in a meshed network including a first terminal and a second terminal. A request from the first terminal for obtaining address information of the second terminal is submitted to a hub. The hub generates a response including the address information and the context information that specifies capabilities of the second terminal. This arrangement has particular applicability to a satellite network (e.g., Very Small Aperture Terminal (VSAT) network) that provides data communication services.

Abstract: A method, system, and computer program product for providing communications services, including determining a type of communications service present in a communications session based on quality of service parameters assigned for the communications session; and adjusting the quality of service parameters based a different type of communications service requested. The types of communications services include real-time and non-real-time communications services.

Abstract: Load is smoothed over multiple bearers in a given spot-beam for a TDMA wireless personal communication system, offering packet data communication services to individual user terminals in shared mode. Load can be smoothed over multiple bearers in a given spot-beam for a TDMA wireless personal communication system which allows maintenance of minimum service levels as a guarantee to individual connections as well as optimizing distribution of users to all available radio channels. It is possible to distinguish between whether a particular bearer is QoS-blocked or demand-blocked. Either a loose smoothing algorithm or a tight smoothing algorithm may be used for the load control operation based on the above dispensation.

Abstract: An approach for transmitting packets over a shared communication channel is disclosed. A satellite terminal (ST) (103, 105, 107, 109) contains a processor that transmits a packet over a transmission slot of the channel using a contention protocol, such as persistent Aloha. The processor reserves an available transmission slot, which is maintained until expiration of a predetermined timeout period.

The present invention also relates to a method for the smoothing of load over multiple bearers in a given sport beam for a TDMA wireless personal communication system which allows maintenance of minimum service levels as a guarantee to individual connections as well as optimizing distribution of users to all available radio channels. The method of the invention is also enabled to distinguish between whether a particular bearer is QoS-blocked or demand-blocked. The method of the invention uses either a loose smoothing algorithm or a tight smoothing algorithm for the load control operation based on the above dispensation.

Abstract: Two types of contention channels are used to accommodate broadband packet data in a satellite communication network. A first contention channel is used by unsynchronized user terminals to access the system and request a traffic channel. The first contention channel is of a sufficient duration to accommodate a RACH message, as well as the timing uncertainty between user terminals within a given spot beam. A second contention channel is shorter in duration than the first contention channel, and is narrowband, so that more than one second contention channel may be transmitted within the bandwidth of the broadband traffic channels. The second contention channels are used by synchronized user terminals for transmitting packet RACH, or PRACH, messages. The more efficient nature of the PRACH channels accommodates the increased overhead associated with bursty packet data, without the capacity cost of the longer duration RACH channel.

Abstract: The present invention is concerned with a method for radio resource allocation for a TDMA wireless radio channel, offering shared bandwidth to multiple connections from multiple end-terminals.

Abstract: The present invention relates to a method for making an uplink transmission plan for a satellite system which supports multiple user terminals per channel and which allows the usage of multiple burst plans at the physical layer, having different duration and bandwidth combinations, as well as individual connections having different known channel conditions when using the system.

Abstract: An approach for minimizing response times in transporting traffic over a packet radio communication system is disclosed. A terminal transmits a packet resource request message that specifies user terminal information using a contention channel according to a prescribed protocol. A gateway station receives the packet resource request message and transmits an assignment message that specifies a channel assignment based upon the user terminal information, wherein the terminal is configured to transmit the packets over a channel is based on the channel assignment. This approach has particular applicability to a satellite communication system.

Abstract: An approach is provided for supporting data communications over a meshed network. A source terminal generates a message to specify information relating to communications capabilities (i.e., context information) of the source for interoperability with a destination terminal. The message is transmitted over the meshed network and may serve as a request for the context information of the destination terminal. This arrangement has particular applicability to a satellite network (e.g., Very Small Aperture Terminal (VSAT) network) that provides data communication services.
