Abstract
A system for allocating a resource to a terminal in a cellular mobile radio network in which each cell of the network is identified by a primary color and a secondary color which correspond to transmission frequencies allocated to it, namely and respectively a set of primary frequencies (FP) and a set of secondary frequencies (FS) whose rate of re-use is higher than that of said primary frequencies (FP), and the terminal is connected to a local cell (A1). The system knows a potential level of interference (N) received by the terminal and allocates said resource to said terminal on a primary frequency (FP) or on a secondary frequency (FS) according to whether said potential level of interference (N) is respectively above or below a first distribution threshold (S1).

A system for allocating a resource to a terminal in a cellular mobile radio network in which each cell of the network is identified by a primary color and a secondary color which correspond to transmission frequencies allocated to it, namely and respectively a set of primary frequencies (FP) and a set of secondary frequencies (FS) whose rate of re-use is higher than that of said primary frequencies (FP), and the terminal is connected to a local cell (A1), in which the system knows a potential level of interference (N) received by the terminal and allocates said resourse to said terminal on a primary frequency (FP) or on a secondary frequency (FS) according to whether said potential level of interference (N) is respectively above or below a first distribution threshold (S1), and in which the system knows a cumulative probability (P (N>S)) of said distribution threshold (S1) by comparing said cumulative probability with the ratio of the number of resources of said set of primary frequencies to the total number of resources.
A system according to any preceding claim, in which said terminal measures the levels received from a particular number of adjoining cells (B2, C3, D2, E1, G2, F1) which have a different primary color to said local cell (A1) and the system knows the number of adjoining cells. (W1, F1) identified as having the same secondary color as the local cell (A1) and establishes said potential level of interference (N) by means of an increasing function of that number.
