Abstract

"PROCESSOS PARA PRIORIZAR TRANSMISSõES DE DADOS EM UM SISTEMA DE RADIOCOMUNICAçãO, PARA RADIOCOMUNICAçãO PARA USO COM UMA PLURALIDADE DE CéLULAS DE COMUNICAçãO QUE SE SOBREPõEM, E, PARA RADIOCOMUNICAçãO ENTRE UMA ESTAçãO BASE E UMA PLURALIDADE DE ESTAçõES REMOTAS". Transmissões de dados ocorrem em um sistema de radiocomunicação entre pelo menos uma estação base e pelo menos uma estação remota. A estação base é capaz de transmitir sinais e receber sinais da estação remota enquanto a estação remota está em uma predeterminada área. Uma prioridade é designada para cada tipo de dados a serem transmitidos e o tipo e prioridade de cada transmissão por vir é determinada e armazenada. Tipos de dados da prioridade mais alta são então transmitidos antes de tipos de dados com prioridades mais baixas. Onde há mais do que uma estação base, haverá uma pluralidade de células de comunicação que se sobrepõem. As estações base radiodifundem sinais em um primeiro período de tempo e estações remotas transmitem sinais em um segundo período de tempo. As estações base estão acopladas a um controlador central que sincroniza o primeiro e segundo períodos de tempo usados pelas estações base em células adjacentes. O número de transmissões em cada célula é monitorado e as durações de cada um do primeiro e segundo períodos de tempo ajustadas para melhorar o uso de largura de banda de transmissão disponível . Transmissões de estações remotas para estações base podem ser transmitidas depois de um predeterminado retardo que é variado em dependência da distância da estação remota da estação base."PROCESSES TO PRIORITIZE DATA TRANSMISSIONS IN A RADIOCOMMUNICATION SYSTEM, FOR RADIOCOMMUNICATION FOR USE WITH AN OVERLAY COMMUNICATION CELLS, AND FOR RADIOCOMMUNICATION BETWEEN A BASE STATION AND A BASE STATION. Data transmissions occur in a radio communication system between at least one base station and at least one remote station. The base station is capable of transmitting signals and receiving signals from the remote station while the remote station is in a predetermined area. A priority is assigned to each type of data to be transmitted and the type and priority of each transmission to come is determined and stored. Higher priority data types are then transmitted before lower priority data types. Where there is more than one base station, there will be a plurality of overlapping communication cells. Base stations broadcast signals in a first period of time and remote stations transmit signals in a second period of time. The base stations are coupled to a central controller that synchronizes the first and second periods of time used by the base stations in adjacent cells. The number of transmissions in each cell is monitored and the durations of each of the first and second time periods adjusted to improve the use of available transmission bandwidth. Transmissions from remote stations to base stations can be transmitted after a predetermined delay that is varied depending on the distance from the remote station to the base station.
