Abstract

L'invention concerne un procédé et un appareil permettant d'émettre des informations d'indication. Selon le procédé, un réseau central acquiert des informations de demande de configuration ; et le réseau central prend une décision d'après les informations de demande de configuration, et envoie les informations de configuration à un UE, les informations de configuration comprenant des informations d'indication à couplage étroit multi-systèmes. Selon la solution technique de l'invention, les fonctions d'un réseau actuel, qui ont été obtenues, sont utilisées efficacement, et le coût opérationnel du réseau est sensiblement réduit tandis que la qualité de service d'un utilisateur et la capacité du système global sont améliorées.
