Abstract

"UM DISPOSITIVO DE COMUNICAçãO PARA INICIAR UMA CHAMADA EM GRUPO EM UMA REDE DE COMUNICAçãO EM GRUPO". A presente invenção apresenta um método e um equipamento para iniciar uma chamada em grupo em uma rede de comunicação em grupo que serve para receber uma lista de membros a partir de um usuário e enviar uma requisição a um servidor para iniciar uma chamada em grupo baseada na lista de membros recebida. O método e o equipamento também servem para receber uma resposta a partir do servidor indicando que o início da chamada em grupo está em progresso, alertar o usuário para prover mídia e enviar a mídia para transmissão depois que um canal de tráfego for restabelecido. O método e o equipamento também servem para uma redução significativa no tempo de acionamento de inatividade total real e latência mediante troca da sinalização da chamada em grupo mesmo quando os móveis estão inativos e nenhum canal de tráfego está ativo.
