Abstract

La présente invention se rapporte au domaine technique des communications. L'invention concerne, dans certains de ses modes de réalisation, un procédé et un dispositif de partage de porteuses non autorisées, qui peuvent résoudre le problème où le déploiement, par des opérateurs multiples, de cellules de spectre non autorisé conduit à un nombre excessif de cellules de spectre non autorisé, ce qui rend difficile l'amélioration de l'agrément d'utilisation en déployant des cellules de spectre non autorisé. Le procédé selon la présente invention est utilisé pour au moins deux stations de base d'opérateur et une deuxième station de base, lesdites au moins deux stations de base d'opérateur comprenant une première station de base, et la deuxième station de base étant une station de base correspondant à une cellule de spectre non autorisé; la deuxième station de base envoie des informations de paramètres auxdites au moins deux stations de base d'opérateur, de sorte que la première station de base parmi lesdites au moins deux stations de base d'opérateur configure la cellule de spectre non autorisé en tant que cellule auxiliaire d'un terminal selon les informations de paramètres, le terminal appartenant à un opérateur correspondant à la première station de base; après que la première station de base a configuré la cellule de spectre non autorisé en tant que cellule auxiliaire du terminal, une transmission de données est réalisée entre la deuxième station de base et le terminal, les informations de paramètres comprenant une identification de cellule physique (PCI) affectée à la cellule de spectre non autorisé par l'opérateur auquel appartient la première station de base. La présente invention est appliquée au cours du processus de partage de porteuses non autorisées par des stations de base d'opérateurs multiples.
