摘要： An error monitor for indicating the quality of communications on a digital communication channel. One or more error detection mechanisms provide indication when an error occurs. After receipt of an error indication, no further indications are detected until a burst error time window has passed. Error indications are stored in a bin. When time since an error indication has been received exceeds a second time period, the event is removed from the bin. When all slots in the bin contain error indications, an indication of the quality of communications on the channel is provided. Parameters can vary with the strength of the received signal to accommodate long range conditions.

摘要： A satellite communication system which performs multicast switching on data cells. A switch 80 receives the data cells at a set of input ports IP1 and directs those including a multicast routing code to a first set of output ports OP2 or OP128. The switch 80 also directs data cells effectively omitting the multicast routing code to a second set of output ports OP1. One or more multicast replication modules 110, 130 are coupled to the first set of output ports and replicate data cells requiring multicast processing. During the processing, the multicast routing code is effectively omitted and the replicated cells are coupled to input ports IP2 or IP 128 so that the replicated data cells are transmitted to the second set of output ports OP1. An outbound processing module 100 is coupled to output ports OP1 for processing the data cells for transmission over a satellite downlink transmitter 104.

摘要： To achieve high throughput by using random reservation scheme, when traffic is heavy in multiple access communication system. Further, to suppress signal delay by using both random reservation scheme and random access scheme, when the traffic is low. Scheduling means holds a flag which indicates that there is no allocation of transmission bandwidth for a long packet reservation information stored in long packet reservation queue. The flag is checked, after the allocation of data transmission bandwidth is started. When the flags are set, bandwidths are allocated firstly for long packets, and secondly for short packets. On the other hand, when the flag is not set, bandwidths are allocated firstly for short packets, and secondly for long packets.

摘要： A method to dynamically assign data rates, for digital data transmission in wireless communication systems, which are just sufficient to meet the needs of the use is presented. The method monitors the data traffic and anticipates when the assigned data rate is inadequate to support the data traffic resulting in a loss of data or when the assigned data rate is more than necessary to support the data traffic and results in inefficient usage of system resources.

摘要： A method is provided to activate a packet data protocol (PDP) context in a cellular network. This may include determining whether users associated with the cellular network may receive multicast or broadcast data and activating the PDP context based on the determination. The determination may be based on a trigger that occurs when a notification is sent to the Serving GPRS Support Node (SGSN). The SGSN may get notified based on a periodic status query, an update message and/or an activation request, for example.

摘要： A multiple access communication network is disclosed having a primary station that is coupled via a transmission medium to a plurality of secondary stations. The primary station is arranged for determining a free channel list comprising the channels, which are not used by any of the secondary stations to transmit information to the primary station. The primary station transmits this list of free channels to the secondary stations. The secondary stations are arranged for attempting to seize one of the channels indicated on the free channel list. If the attempt to seize a channel was successful, the secondary stations keeps using the channel it seized until it has all available information transmitted. If the secondary station stops using the channel, the primary station will include the channel again in the free channel list.

摘要： A device for prepaid recording of digital audio signals. In a system where digital radio signals are received in an encoded format, a digital converter that is enabled by a smartcard module is employed to convert encoded digital signals to decoded digital signals for recording onto a digital storage media. A smartcard having a prepaid account balance is employed to authorize and control the recording of digital signals. A buffer is advantageously employed to store a quantity of digital signals prior to recording.

摘要： A system, apparatus and method provide wireless communications to a geographical area. The system includes at least one atmospheric platform serving as a central relay or node using a star network topology for the geographic area. The atmospheric platform carries a payload that comprises communications equipment. The system further includes a plurality of user equipment units located within the geographic area and at least one ground station or gateway for providing an information pathway between the user equipment units. The gateway has network processing and switching equipment for routing the information between the users. A wireless trunkline carries signals between the gateway and the atmospheric platform. The apparatus and method comprise gateway and payload uplink portions and downlink portions. The downlink portions aggregates and de-aggregates user generated information from the platform to the gateway. The uplink portions de-aggregate and aggregate the information and route the information with the network switching equipment to intended user equipment units, from the gateway to the platform. The gateway may also provide information pathways from the platform to user equipment units outside of the geographic area through existing communications infrastructure. The system, apparatus and method utilize a wide, non-contiguous band of spectrum in point-to-point links to carry the combined signal traffic from a multitude of subscribers on the ground to the communications switches at the gateway and vice versa, via the airborne platform. The use of wireless trunklines enables all types of switching, including circuit, cell, packet, or frame, or any combination thereof, to be performed by standard equipment housed in facilities on the ground rather than by specially designed equipment located on the airborne platform.
