Abstract

"PROCESSOS DE TRANSFERêNCIA DA CONEXãO DE ESTAçãO MóVEL DE UMA PRIMEIRA ESTAçãO ESTAçãO BASE PARA UMA SEGUNDA ESTAçãO BASE E DE REALIZAçãO DE VERIFICAçãO SOBRE UMA ESTAçãO MóVEL POR UMA SEGUNDA ESTAçãO BASE ANTES DE UMA TRANSFERêNCIA E SISTEMA DE TELECOMUNICAçãO CELULAR". Um processo de e aparelho para proporcionar contínua verificação de uma estação móvel para operações de transferência em um sistema de telecomunicação celular são descritos. Em uma concretização da presente invenção, uma estação móvel (MS) tem uma conexão sem fio estabelecida com uma primeira estação base (BS1). Uma segunda estação base (BS2) recebe as transmissões de enlace ascendente emitidas para BS1 pela MS assim que entra em alcance de recepção. BS2 imediatamente inicia um procedimento de verificação sobre a MS para determinar se uma conexão satisfatória pode ser efetuada. A etapa de verificação é iniciada pela segunda estação base antes de m procedimento de transferência ser iniciado dessa forma reduzindo o volume de sinalização entre o MSC e as estações base associadas. Uma vez que a verificação é iniciada com antecedência, ocorre através de um período de tempo relativamente mais longo resultando em confiabilidade de transferência aperfeiçoada."PROCESSES FOR TRANSFERING THE MOBILE STATION CONNECTION FROM A FIRST BASE STATION TO A SECOND BASE STATION AND PERFORMING A VERIFICATION ON A MOBILE STATION BEFORE A SECOND BASE STATION BEFORE A TRANSFER AND A TELEPHONE SYSTEM. A method and apparatus for providing continuous verification of a mobile station for transfer operations in a cellular telecommunication system are described. In one embodiment of the present invention, a mobile station (MS) has a wireless connection established with a first base station (BS1). A second base station (BS2) receives the uplink transmissions sent to BS1 by the MS as soon as it comes into receiving range. BS2 immediately initiates a verification procedure on the MS to determine whether a satisfactory connection can be made. The verification step is initiated by the second base station before a transfer procedure is initiated in this way by reducing the signaling volume between the MSC and the associated base stations. Once verification is started in advance, it takes place over a relatively longer period of time resulting in improved transfer reliability.
