CA 2314101

A telecommunications system and method is disclosed for providing adaptive channel allocation for indoor cellular systems, which utilizes interference measurements on both the down-link channels and the up- link channels. This can be accomplisched by using a Stand Alone Dual Channel Scanner (SADCS) to assist indoor cellular systems in allocating traffic channels on the basis of interference from external systems, which measures both the up-link and the down-link at the same time. A number of SADCSs can be placed at strategically located points in the building to measure interference on a channel by channel basis, and to communicate the results to the indoor base station, which can then allocate traffic channels with high confidence of maintaining a good speech quality.

L'invention concerne un système et un procédé de télécommunications qui permettent une allocation dynamique de voies pour des systèmes cellulaires intérieurs, et utilisent des mesures de brouillage à la fois sur la liaison descendante et sur la liaison montante. Le procédé se met en oeuvre au moyen d'un scanner autonome à deux voies (SADCS) servant d'auxiliaire aux systèmes cellulaires intérieurs pour affecter des canaux de trafic sur la base du brouillage émanant de systèmes extérieurs. Ces SADCS mesurent en même temps la liaison montante et la liaison descendante. Un certain nombre de SADCS peuvent être placés à des emplacements stratégiques dans le bâtiment pour mesurer le brouillage canal par canal, et pour communiquer les résultats à la station de base intérieure, laquelle peut ensuite affecter en toute fiabilité des canaux de trafic assurant une bonne qualité de communication.
