METHOD OF SHARING A MOBILE TELECOMMUNICATION NETWORK WITH RESTRICTED ACCESS AND TELECOMMUNICATION NETWORK IMPLEMENTING THE METHOD

摘要

The invention relates to a method of sharing a mobile telecommunication network with restricted cell access in non-shared cells and such a telecommunication system. The intended use of the invention is to make it technically feasible to differentiate radio coverage between partners sharing a common third generation, e.g. WCDMA, network in areas where expanded coverage results in non-shared cells. The present invention proposes to use the cell access classes. A unique subset of the first ten access classes is allocated to each sharing partner. Each operator then assigns the given set of access classes among its subscribers. In areas (3A, 3B) where only subscribers of one of the sharing partners should have access to the radio network, the cell's access restriction is set to only allow customers from one of the uniquely assigned sets of access classes, i.e. the ones corresponding to the sharing partner.
