Appl. No.:

8/560605

Yih Guang Jan - Phoenix AZ
Kenneth Maynard Peterson - Phoenix AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04B 7185

US Classification:

342354

Abstract:

In a satellite cellular communication system (10), a phased array antenna (41) includes a dynamic beamformer (50) that provides individual antenna beams (35) within which communications with subscriber units (26) take place. The satellites (12) are located in several orbits (14). As the satellites move with respect to Earth's surface, each of the antenna beams is stepped backward (104) to compensate for the satellites movement. After each satellite travels a distance equal to a predetermined portion of the satellites' spacing in the orbit, each satellite's antenna beams are stepped forward (116) to replace the previous satellite's footprint. Accordingly, cell-to-cell hand-off is not required for subscriber units communicating within an antenna beam.

International Classification:

H04B 7185

US Classification:

455 17

Abstract:

A method of predicting cell-to-cell hand-offs of mobile subscribers for a satellite cellular communications system. Each satellite of a constellation projects a number of beams or cells upon the earth for communication with mobile subscribers. The satellite transfers (hand-offs) communications links from cell to cell as the satellite moves over the mobile subscriber. Since the movement of the satellite is stabilized in three directions, the projection of the beams or cells follows a predictable path across the face of the earth. Each satellite moves across the earth in one direction. Once a subscriber is located within one cell, the next cell to which the mobile subscriber is handed-off may be determined from the geographic position. For mobile users which are close to boundaries between cells, additional position location may be determined by the calculation of bit error rates. The results of these bit error rate measurements then indicate the identity of the cell which is to receive the hand-off of the mobile user.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q 700

US Classification:

455 121

Abstract:

A method and apparatus for controlling communication channel access in a communication system (10) determines channel allocations (106) which represent limits on communication channel access and conforms operations of the system (10) to the channel allocations. The channel allocations are determined by dividing a surface which emanates signals from communication units (26) into elemental areas, collecting past traffic data (102) describing past communication channel usage by the communication units (26) located in the elemental areas, generating a traffic model (104) for a future time interval based on the past traffic data, and determining the channel allocations (106) based on the traffic model.

International Classification:

H04B 7185
H04M 1100

US Classification:

455 131

Abstract:

A system for facilitating global cellular/trunked mobile communication is disclosed. This system permits communication with hand held and mobile mounted cellular telephones. The system permits two-way communications anywhere on or above the earth up to a particular height above the earth of several hundred nautical miles. The system employs a number of low-earth orbiting satellites moving about the earth in orbit. Links are provided from the satellites directly to the users and via the public switched telephone network to other users. The satellites are interconnected via links in a ring structure surrounding the earth. Switching is performed by each of the satellites. In addition, each of the satellites hands off a call as it moves out of the range of a particular user.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04J 322

US Classification:

370332

Abstract:

Methods (600, 700), an access controller (350), and a communication system (300) for optimizing utilization of a wireless communication link in a limited bandwidth communication system or network are provided. Statistical multiplexing is achieved by partitioning a wireless communication link (240) into multiple communication channels (250) and assigning communication sources (220) to communicate information over an air interface for a predetermined time interval, where the number of communication sources (220) assigned to the communication channels (250) during a particular time interval exceeds the number of available communication channels (250). The methods (600, 700), access controller (350), and communication system (300) disclosed also allow a system operator to provide varying levels of quality of service (QoS) guarantees in a communication system or network using statistical multiplexing by designating varying levels of QoS among the communication channels (250).

International Classification:

H04B 7185
H04B 719

US Classification:

342352

Abstract:

There is provided a method and means for controlling the amount of overlap and gaps in coverage of antenna pattern cells of a moving satellite communication system, by determining the relative spatial location of overlapping or gaping cells of converging or diverging satellites as a function of time; determining a point where antenna coverage of one or more cells from a first moving satellite will overlap or gap one or more cells from a second satellite; and turning off or on one or more of the overlapping or gaping cells so as to eliminate interference therebetween without leaving substantial coverage gaps between adjacent antenna patterns.
