Abstract:
A cellular radio network including allocated radio frequencies reused in cells, comprising:said allocated radio frequencies being divided into regular radio frequencies for which lower frequency reuse is utilized to achieve a seamless overall coverage, and super-reuse frequencies to which high frequency reuse is applied to provide a high traffic carrying capacity;at least some of said cells having both at least one regular frequency and at least one super-reuse frequency, so that said at least one regular frequency is intended to serve primary in cell boundary regions and said at least one super-reuse frequency is intended to serve primary in the vicinity of a base station; anda controller which controls traffic load distribution in a cell between said at least one regular and said at least one super-reuse frequency by intra-cell handovers induced by estimated interference on said at least one super-reuse frequency,wherein a BCCH frequency of the cell is a regular frequency, and wherein a radio frequency assigned in call-setup and handover from another cell is always a regular frequency.
