Abstract: Provided is a resource allocation apparatus and method in a multi frequency-time division multiple access (MF-TDMA) broadband satellite system, which can employ timeslots in a return link with a maximum throughput promptly, by dividing a timeslot assignment problem minimizing a weighted sum in response to a resource allocation request from terminals into a first sub-problem for deciding the number of timeslots to be allocated to each class of each terminal and a second sub-problem for selecting timeslots to be allocated to each terminal. The method includes the steps of accumulating an amount of resource requests created during a super-frame period for each terminal, deciding a resource allocation amount to be allocated to each class, and selecting and mapping timeslots to be allocated to each terminal based on the decided resource allocation amount. This invention may advantageously be applied to the MF-TDMA broadband satellite system.

Abstract: A method for determining charges in real time for value-added services in a telecommunication network, having an intelligent network structure, in which a caller selects a value-added service by dialing an associated destination number. This destination number is intercepted in an intelligent network element of the telecommunication network and is converted into a special access number for the value-added service. A connection is established between the intelligent network element and the value-added service provider through the use of this destination number. The value-added service provider transmits the applicable rate for the use of the requested value-added service to the mobile telephone network operator in the form of a new destination number for the requested value-added service. The new destination number is evaluated in the intelligent network element and a connection is established between the caller and the value-added service with the new destination number at the stated rate.

Abstract: A system and method for communicating between ground stations and mobile satellites effectively eliminates the need for transferring information from one ground station to another. Communication between a ground station and a mobile satellite is accomplished via an intermediate network of geosynchronous control satellites. The mobile satellite is positioned within a three-dimensional cellular grid formed by the network of geosynchronous satellites. This system is particularly applicable to a terrestrial network communicatively coupled to the geosynchronous network via one or more ground stations. The terrestrial network of ground stations no longer needs to perform expensive, time-consuming and manual synchronization and hand-off procedures.

Abstract: Systems and methodologies are described that facilitate scrambling of downlink reference signals utilizing a pseudo-random sequence (PRS) corresponding to a primary synchronization code (PSC) and secondary synchronization code (SSC) combination. Utilization of the combination allows for orthogonal sequencing to be removed from the scrambling. This can be beneficial, for example, where resources required for orthogonalizing the reference signal outweigh the benefit of utilizing the orthogonal sequences. In such scenarios, selective scrambling can be utilized such that the orthogonal sequence or instead the PSC/SSC combination can be provided to leverage advantages of both mechanisms in the given scenarios.

Abstract: Autoband's distributed networking intelligence provides a novel architecture capable of dynamically reconfiguring communications pathways consisting of links whose transmission media are opportunistically and dynamically selectable. At least one constituent node in such automatically configurable transient pathways is mobile, for example, information (source) server, intervening router node(s), gateway server and/or client device.

These communications may consist of point-to-point or multicast links. An economic market-based approach further assures allocation of available network resources (i.e., bandwidth and processing) needed to achieve the most optimally resource efficient communications pathway configurations for the totality of communications.

Abstract: Determining the amount of resources that needs to be provisioned for a wired backhaul link of a wireless network using a probabilistic approach that makes the determination based at least in part on the type of coding scheme selection algorithm used to encode data transmitted by the transceiver to the wireless device over the air interface of the wireless network. Because the type of coding algorithm used depends on the amount of traffic at the air interface, variations in the coding algorithms used over a given period of time can be used to accurately determine the amount of bandwidth or resources that will be required on the backhaul link. Consequently, the amount of resources that should be provisioned for the backhaul link can be accurately determined.

Abstract: The present invention allows mobile terminals to initiate calls to either PSTN or non-PSTN addresses through a cellular interface. In operation, the mobile terminal will determine a terminating address to which a call is to be initiated based on user input or selection. The mobile terminal will then determine whether the terminating address should be used to directly initiate a call through the cellular interface. When the terminating address should be used to directly initiate the call, the mobile terminal will directly initiate the call using the terminating address. When the terminating address should not be used to directly initiate the call, the mobile terminal will send the terminating address to a service node. The service node will then initiate an indirect call process using the terminating address to establish the call between an endpoint associated with the terminating address and the cellular interface of the mobile terminal.

In addition to communicating like mode signals from a transmitter to a receiver, the relay device may be used in a dual mode communication system to translate signals from the one mode to another. A translator may direct a transmitter to modulate a signal on a different carrier frequency, convert one protocol into another protocol, or both.
