摘要： A method and apparatus for accessing a communication system relies on the use of varying access probabilities for subscribers or messages of varying priority. A serving infrastructure entity (110) determines access probabilities in response to known system parameters like the current rate of access attempts for each priority class of user/message. Values representative of these access probabilities are then transmitted to the subscriber unit(s) (105), for example by use of a system broadcast channel or control channels. These values are then used by the subscriber units in determining when to access an uplink channel. A temporal and/or proportional priority distribution approach is preferably used in determining the access values. As a result of this contention-based prioritization, an expedited access is achieved by higher priority units/traffic, thus increasing their throughput.

摘要： In a multiple access transmission system it can be desired to have the possibility to change the type of access protocol in response to the traffic demand of subscriber stations in order to prevent deterioration of the transmission efficieny. In order to do so, the primary station (2) transmits to the secondary stations (2, ...12) a channel indicator, indicating where in the uplink frame the secondary station can submit its access requests. In a preferred embodiment, the primary station submits also the message the secondary station has to use when submitting an access request. Applications of the invention include multimedia networks using CATV systems.

摘要： A system controller (102) is used in a communication system (100) which has a set of inbound channels. The system controller (102) includes a processing system (204) for generating a first message which is transmitted to selective call devices (106). The first message includes a subset identifier which identifies an ALOHA subset of the set of inbound channels for use by a set of the selective call devices (106). A selective call device (106) includes a transmitter (708) and a processing system (710). The processing system (710) identifies the ALOHA subset of the set of inbound channels, and generates a second message and couples the second message to the transmitter (708) using an ALOHA protocol on an inbound channel which is in the ALOHA subset of the set of inbound channels when the second message is a first type. The transmitter (708) transmits the second message.

摘要： The invention is a method and apparatus for providing an Alert With Information Message signal between a mobile switching center (36) and a base station (34) in a cellular communication system. The invention recognizes that current provisions of the IS-634 standard lack support for certain required functionality on the interface between a mobile switching center (36) and a base station (34), or the A-Interface. An Alert With Information Message signal is introduced on the A-Interface to support the required functionality. Introduction of the Alert With Information Message provides support for reliable call processing on the A-Interface for the call waiting procedure, the hard handoff procedure, and the resolution of a glare condition. A message generator (38) in the mobile switching center (36) generates the Alert With Information Message, which is transmitted to message receiver (40) in the base station (34) when needed.

摘要： A digital beamforming network for transmitting a first number of digital information signal using a second number of antenna array elements is disclosed. Assemblers are used for assembling one information bit selected from each of the information signals into a bit vector. Digital processors have an input for the bit vector and a number of outputs equal to the second number of antenna elements and process the bit vector. Finally, modulation waveform generators coupled to each of the second number of outputs generate a signal for transmission by each antenna element.

摘要： A two-way satellite communications system includes an Earth station communicating with a plurality of remote terminals using a network access protocol that facilitates low power consumption by the terminals. The Earth station generates forward link TDM packet data transmissions on one or more satellite channels, and detects, despreads and decodes multiple concurrent return link slotted CDMA packet transmissions on one or more satellite channels. It communicates through a wired connection with a packet processing center which ultimately both delivers return link packet data to end-customers and receives forward link packet data from end-customers. The remote terminals receive, process and act upon forward link TDM transmissions on one or more satellite channels, and generate slotted spread spectrum CDMA transmissions on the return link on one or more satellite channels. The remote terminals communicate with a local digital data source and/or sink, digitize one or more local analog sensor signals, enter into a sleep mode to minimize the terminal's power consumption, and access the satellite communications network in accordance with the system network access protocol.

摘要： Satellite footprints (16a, 16b, 16c) are partitioned into elongate spanning cells (18) and multiple elongate segments (22). The elongate spanning cells (18) resemble long strips that extend along an entire footprint (16a, 16b, 16c). The alignment of the elongate spanning cells (18) along a footprint (16a, 16b, 16c) is determined by a correction angle PHI , which compensates for the changing relative motion of the Earth's surface at various latitudes.

摘要： The invention relates to a data transmission method utilizing combined CDMA/FDMA multiple access, and a corresponding radio system. Complementary codes are used as CDMA spreading codes in the system. Transmissions on frequency channels used are synchronized with each other. To increase frequency efficiency, at least some of the frequency channels are interlaced frequencies (f0, f1, f2, f3) having a mutual frequency difference selected from the zero points of auto- and cross-correlation functions calculated as a function of the frequency offset of the CDMA spreading codes used on the frequency channels.
