Patent ID: 8565750

Claim:
A method for generating a list of cells, said method comprising: receiving an indication, from a selected first network node operating at a first frequency, for indicating a second frequency of a first set of neighbor network nodes, wherein said second frequency is different from said first frequency, and wherein said indication further indicates a presence of a second network node located in said first set of neighbor network nodes; measuring reception quality of a signal from said second network node in response to receiving said indication; and receiving system information from said second network node when said reception quality exceeds a threshold; identifying a rate of speed of a user equipment (UE); identifying a set of at least two candidate neighbor network nodes based upon said received system information only when the identified rate of speed exceeds a threshold, wherein said set of at least two candidate neighbor network nodes is included in said first set of neighbor network nodes, and wherein said set of at least two candidate neighbor network nodes comprises an identity of at least one network node that is different from an identity of said second network node; receiving a list from said selected first network node; receiving a list of allowed identification tags from said second network node; excluding said second network node from said set of at least two candidate neighbor network nodes when an identification tag associated with said second network node is not included in said list; identifying a second set of neighbor network nodes that are communicating at said first frequency; and generating a combined neighbor list comprising said first set of neighbor network nodes and said second set of neighbor network nodes, wherein if a macro cell covers a specific area as a plurality of micro cells, each frequency of neighboring cells within the first set of neighbor network nodes and the second set of neighbor network nodes is represented by a center frequency and bandwidth in a specific layer, wherein if the specific area is covered by collocated cells for different layers, a first rule is created for determining of a combined neighbor list in a different layer from the combined neighbor list of a cell on which the UE is camping, and wherein if the specific area is covered by no-collocated cells for different layers, a second rule is created by adding a combined neighbor list of one or more cells, which is included in cell information, with the combined neighbor list of a cell on which the UE is camping.
