US 9,794,911 B2 · Method and radio network node for determining route update radius

Abstract

The present disclosure provides a method implemented by a radio network node for determining a Route Update Radius (RUR) for a Radio Base Station (RBS) and the radio network node. The method comprises determining a first radius (RUR_CCH) which defines a largest circular area centered at the RBS and excluding a first number of RBSs among the RBS's neighboring RBSs, wherein CCH occupancies for the first number of RBSs are higher than a CCH occupancy threshold. The method further comprises determining a second radius (RUR_ACH) which defines a smallest circular area centered at the RBS and covering a second number of RBSs among the RBS's neighboring RBSs, wherein ACH occupancies for the second number of RBSs are higher than an ACH occupancy threshold. The RUR is determined based on a comparison between the first radius (RUR_CCH) and the second radius (RUR_ACH).

A method implemented by a radio network node for determining a Route Update Radius (RUR) for a Radio Base Station (RBS), comprising:

determining a first radius (RUR_CCH) which defines a largest circular area centered at the RBS and excluding a first number of RBSs among the RBS's neighboring RBSs, wherein Control CHannel (CCH) occupancies for the first number of RBSs are higher than a CCH occupancy threshold;
determining a second radius (RUR_ACH) which defines a smallest circular area centered at the RBS and covering a second number of RBSs among the RBS's neighboring RBSs, wherein Access CHannel (ACH) occupancies for the second number of RBSs are higher than an ACH occupancy threshold;
and
determining the RUR based on a comparison between the first radius (RUR_CCH) and the second radius (RUR_ACH), wherein determining the RUR comprises:
if the first radius (RUR_CCH) is larger than or equal to the second radius (RUR_ACH), determining the RUR as the first radius (RUR_CCH);
and
if the first radius (RUR_CCH) is smaller than the second radius (RUR_ACH), determining the RUR based on a comparison between the first number and the second number.
