Claim:
1. A method of managing neighbour relations between cells comprising the steps of: receiving requests for admission of a neighbour relation; adding tokens in respect of each request; removing tokens as time passes; and admitting the neighbour relation if the number of tokens passes a threshold, wherein in an additional assessment to decide to admit the neighbour relation, criteria are evaluated relating to negative impacts on cells with a normal frequency of handovers due to cells with increased handover frequency that share the same transport network resources with the cells that have a normal frequency of handovers, wherein the negative impacts to be evaluated in the additional assessment relate to a measured average end-to-end delay, a number of hops, or a cumulative cost comprising weights of intermediate links between the cells, wherein receipt of a measurement report identifying a cell for which a neighbour relation has not been established leads to adding predefined numbers of tokens in respect of that cell, and wherein the number of tokens added following handling of a measurement report reflects a weight given to the source of the measurement report based on properties of a reporting terminal or a subscriber who owns the terminal.
