A method is provided for interconnecting base stations of a cellular network via a transport network which comprises a plurality of network elements (NEs), wherein at least two of the plurality of NEs are collocated with respective base stations. The method comprises the steps of: establishing in the TN at least one proximity group that comprises a plurality of geographically adjacent NEs; establishing a logical grid connectivity between NEs that are members of the same proximity group to enable direct communications there-between, thereby enabling establishment of communications paths between base stations collocated with the at least two of the plurality of NEs, wherein that path extends via the at least two respective NEs communicating directly there-between,
