Abstract

Мобільна система безпровідного зв'язку включає базові станції першого типу, що працюють згідно з першим ефірним інтерфейсом, і базові станції другого типу, що працюють згідно з другим ефірним інтерфейсом. Запропоновано спосіб і пристрій для передачі зв'язку з мобільною станцією у системі від першої базової станції, що є базовою станцією першого типу, до другої базової станції, що є базовою станцією другого типу. Встановлюється канал зв'язку через перший ефірний інтерфейс між мобільною станцією і першою базовою станцією. Здійснюється прийом даних від мобільної станції, переданих у відповідь на сигнал, прийнятий цією мобільною станцією через другий ефірний інтерфейс від другої базової станції, без суттєвого порушення каналу зв'язку з першою базовою станцією. Мобільна станція передає зв'язок від першої базової станції до другої базової станції у відповідь на прийом даних від неї. Зокрема, передбачено спосіб міжсистемної передачі зв'язку від багатоносійної системи до системи прямого розширення. Через мобільну станцію забезпечується доступ до інформації про часові параметри.
