Abstract

"SISTEMA DE TELECOMUNICAçõES, Nó DE SUPORTE DE PONTO DE CONEXãO, MéTODO PARA COMUNICAR PACOTES INTERNET ENTRE UMA REDE DE COMUNICAçõES DE DADOS EM PACOTES EXTERNA E UMA REDE DE RáDIO EM PACOTE, PROGRAMA DE COMPUTADOR, E, PRODUTO DE PROGRAMA DE COMPUTADOR". Um sistema de telecomunicações para comunicar pacotes Internet entre um equipamento de comunicações móvel de usuário formando um nó correspondente, e um nó móvel via uma rede de comunicações de dados em pacote externa. O sistema compreende uma rede de rádio em pacote provendo diversos portadores de dados em pacote para comunicar pacotes Internet com nós anexados à rede de rádio em pacote. Cada um dos portadores é definido com respeito a um endereço fonte dos pacotes Internet, a rede de rádio em pacote incluindo um nó de suporte de ponto de conexão operável para prover uma interface entre a rede externa e a rede de rádio em pacote. O nó de suporte de ponto de conexão (GGSN) é operável para detectar (56) se um pacote Internet é para prover uma atualização de ligação para o nó correspondente de um primeiro endereço fonte do nó móvel para um endereço 'aos cuidados de' do nó móvel. Se o pacote Internet for uma atualização de ligação, o nó de suporte de ponto de conexão permite (514) o egresso de pacotes Internet enviados a partir do nó correspondente, possuindo o endereço 'aos cuidados de' do nó móvel como o endereço de destino para a rede externa. Obtendo o endereço 'aos cuidados de' do nó móvel a partir da atualização de ligação e permitindo o egresso de pacotes do nó correspondente possuindo este endereço 'aos cuidados de' como endereço de destino nos cabeçalhos de pacote Internet, é provida uma medida de segurança, que pode evitar ou pelo menos impedir o roubo de serviço. O roubo de serviço pode ocorrer se um usuário inescrupuloso usa um endereço de destino não autorizado para pacotes de dados IP enviados do equipamento de usuário móvel atuando como nó correspondente e tendo um endereço legítimo no campo de extensão salto-por-salto e um endereço não autorizado no endereço de campo de destino.
