Method and apparatus for generating a neighbor cell list
First Claim
1. A method for use in a controller in a radio network including a number of cells, in which network a user equipment communicates with at least one cell defining an active set, the user equipment (UE) having a velocity vector including position, speed, and direction, comprising:
- receiving information related to the velocity vector;
filtering a neighbor cell list associated with active set using the velocity vector related information to create a filtered neighbor cell list; and
transmitting the filtered neighbor cell list to the user equipment thereby enabling measurement of pilot signal strength for cells in the filtered neighbor cell list.

Abstract
A user equipment (UE) communicates with at least one cell defining an active set. A velocity vector including position, speed, and direction is associated with the UE. A radio network controller receives information related to the velocity vector and creates a filtered neighbor cell list by filtering a neighbor cell list associated with the active set. The filtering depends on the velocity vector related information. The controller transmits the filtered neighbor cell list to the user equipment so that pilot signal strength is measured for cells in that list.
