20080207207 | Self Configuring and Optimization of Cell Neighbors in Wireless Telecommunications Networks - The present invention relates to a cellular communications network and in particular to the problem of identifying cells for neighbor lists, or handover candidates when the cells are identified by a limited number of non-unique identities. The present invention includes a method for a radio base station, wherein the base station receives reports from one or more terminals in neighbor cells quality and non-unique identities. The match is sought in a neighbor cell list non-unique identity with a unique cell identity. If the match cannot be made without ambiguity, the base station causes the terminal to detect the unique cell identity. If the reason for the ambiguity is the particular cell is not included in the neighbor cell list it is included when its unique identity has been established. The uniquely identified cell is used if it is determined to perform a handover. | 08-28-2008 |
