Enhanced neighbor relation building algorithm for WCDMA and LTE Networks

This paper provides an enhanced algorithm to design the neighbor cell list (NCL) in WCDMA and E-UTRAN. NCL design has been conventionally performed based on RF coverage data obtained from off-line coverage simulations tool, which requires expensive arrangement of tools and information to run. As a result, automatic and continual update of neighbor relation in the mobile network using SON (Self Optimization Network) takes high cost and complexity. The new algorithm proposed in this paper can build the reliable neighbor relations with must less efforts and information requirements like coverage simulation. The reliability of the algorithm was also verified using actual application to a live network.
