摘要： A system, method and computer-readable medium for allocating multiple subscriptions to a single mobile terminal thereby allowing concurrent termination of multiple calls at the mobile terminal are provided. A mobile terminal adapted to terminate multiple concurrent calls is described. In one implementation, a network need not have any configuration data regarding the multi-line capabilities of the mobile terminal. In other implementations, network-centric mechanisms are provided for allowing multiple concurrent calls to be terminated by a mobile terminal. Multiple concurrent calls may be terminated at a mobile terminal on separate carrier frequencies or alternatively may be terminated on a common carrier frequency.

摘要： A communication system and method for a deep space spacecraft receiver to perform post-processing to dynamically combine received signal power coherently for pre-processed signal streams radiated non-coherently from a distributed, multiple element, Ka-band transmitting array via multiple concurrent propagation paths. Mutually orthogonal data and pilot signals travel though the multiple propagation paths. A pre-processor utilizing wavefront multiplexing restructures signal streams on the ground into multi-channel wavefrom structures along with injections of pilot signals for diagnostic and probing purposes. These restructured, or “wavefront multiplexed” (WFM) signals are transmitted through propagation channels to a receiver on the spacecraft, wherein adaptive equalization and wavefront de-multiplexing coherently separates the mixtures of received WFM signals. Transmitting power can be dynamically allocated for the multiple concurrent data streams, radiated to different spacecraft within the same field of view according to continuously changing demand by changing the relative input power ratios of the WFM signal mixtures.

摘要： Methods, systems, and devices are described for managing satellite communications through the deployment of a fleet of multi-beam satellites serving overlapping and non-overlapping spot beams. In these methods, systems, and devices, a first communication service associated with a relatively wider spot beam of a first satellite is provided to a first coverage area having multiple terminals. A second communication service associated with a relatively narrower spot beam (e.g., high-gain spot beam) of a second satellite is provided to a second coverage area located within the first coverage area. A subset of terminals located within the second coverage area is identified, and the terminals of the identified subset are transitioned from the first communication service of the wide spot beam of the first satellite to the second communication service of the high-gain spot beam of the second satellite.

摘要： Message are broadcast in a vehicular environment using a network of nodes, wherein each node includes a transceiver and a processor arranged in a vehicle, and a bandwidth of the network is partitioned into a control channel (CCH) and multiple service channel (SCH). Time is partitioned into alternating control channel intervals (CCHI) and service channel intervals (SCHI). A source node detects an event and broadcasts a message related to the event. The message specifies current channels and next channels used by the source node to broadcast the message. The message is received in a set of relay nodes. Then, each relay node that receives the message rebroadcasts the message during the SCHI on the CCH or any other channels not specified in the message.
