Claims (10)

1. Способ беспроводной связи между первой сетью и второй сетью, позволяющий мобильной станции (MS), подписанной в первой сети, осуществлять связь, используя вторую сеть, заключающийся в том, что запоминают идентификатор мобильной станции, получают от первой сети информацию об аутентификации на основе идентификатора мобильной станции, используют информацию об аутентификации из первой сети для создания ключа, заменяют ключ ключом аутентификации, используемым в первом алгоритме, для аутентификации мобильной станции, и заменяют ключ ключом шифрования, используемым во втором алгоритме, для шифрования сообщений между мобильной станцией и второй сетью.
2. Способ по п.1, в котором созданный ключ происходит из первой сети.
3. Способ по п.1, в котором первый алгоритм выполняют во второй сети.
4. Способ по п.1, в котором ключом аутентификации являются совместно используемые засекреченные данные SSD-A.
5. Способ по п.1, в котором ключом шифрования являются совместно используемые засекреченные данные SSD-B.
6. Способ по п.2, в котором первой сетью является сеть глобальной системы мобильной связи (GSM).
7. Способ по п.2, в котором второй сетью является сеть множественного доступа с кодовым разделением каналов (CDMA).
8. Способ по п.2, в котором первым алгоритмом является алгоритм аутентификации и шифрования речи в системе сотовой связи (CAVE).
9. Способ по п.7, в котором вторым алгоритмом является алгоритм CAVE.
10. Мобильная станция, содержащая средство для приема ключа от первой сети, средство для замены ключа первой сети на ключ аутентификации, используемый в первом алгоритме, для аутентификации мобильной станции и средство для замены упомянутого ключа ключом шифрования, используемым во втором алгоритме, для шифрования сообщений между мобильной станцией и второй сетью.
