- 43seguir à transmissão seguinte da palavra do canal D (159) chamando o primeiro aparelho telefónico, este envia uma mensagem de pedido de uma interligação (1β7)· A estação de base (3) responde com uma mensagem a garantir a interligação (169) e esta é estabelecida. A estação de base (3) e o aparelho telefónico manual (11) permutam então as palavras do canal 3) (171) utilizando o multi-plex 2, até que a estação de base (3) instrua a permuta ao multiplex 1. Eles vão então trocar as transmissóes (173) do multiplex 1, transportando o canal B, e a conversação telefónica inicia-se. REmNDICAgÕES ia. - Sistema de telecomunicações que compreende uma pluralidade de estações de base distribuídas, cada uma ligada operacionalmente a uma rede pública de telecomunicações comutada, sendo cada estação de base adaptada para cooperar com uma ou várias unidades, de uma pluralidade de unidades telefónicas portáteis sem fios por intermédio de uma multiplicidade de canais de comunicação digital sem fios, que operam com base num sistema duplex por divisão de tempo, caracterizado pelo facto de a unidade de base ser operada após a detecção de uma chamada que entra na rede pública comutada, para pesquisar todas as unidades telefónicas portáteis sem fios por meio da 44 transmissão repetitiva da identidade das unidades portáteis a serem ligadas à chamada de entrada num canal seleecionado; e a unidade de "base preparada ser para intercalar, em cada operação de pesquisa, uma mensagem de sinalização e cada unidade portátil ser montada para explorar os canais sem fios num intervalo pré-determinada, e a unidade de hase ser adaptada para adiar o envio de uma mensagem de toque de campainha a qualquer das unidades portáteis até que tenha decorrido um período de tempo pré-determinado desde o início da acção de pesquisa, sendo o período pré-determinado suhstancialmente igual ao ou maior do que o intervalo de tempo pré-determinado. 2a. - Sistema de telecomunicações de acordo com a reivindicação 1, caracterizado pelo facto de a mensagem de sinalização ser utilizada pela estação de hase para instruir cada unidade portátil que tenha sido pesquisada para não activar um dispositivo de chamada sonoro instalado em cada unidade portátil. 3a. - Sistema de telecomunicações de acordo com a reivindicação 2, caracterizado pelo facto de cada mensagem de sinalização ser ainda usada pela estação de hase para simultaneamente instruir cada unidade portátil que tenha sido pesquisada, a fim de activar o seu dispositivo de chamamento sonoro associado. 4a. - Sistema de telecomunicações de acordo com a reivindicação 3, caracterizado pelo facto de cada unidade portátil e a unidade de hase compreenderem um rádio receptor/transmissor controlado por um correspondente controlador do sistema, sendo os referidos controladores do sistema preparados para estabelecer um canal de comunicação entre a respectiva unidade portátil e uma unidade de hase e controlar a transferência das mensagens entre elas. lishoa, 29 de Março de 1990 0 Agente Oficial da Propriedade IndustrialÍl Lí Aconb fmêvMm1 Cflciil u3 Pícprioíhdii Ir,,.
