Oh, sorry, looks like i repost this thread http://www.finetopix.net/images/smilies/sad.gif: http://www.finetopix.com/showthread.php?26751-Neighbor-cell-relation-list-and-measured-cell-identity-management-in-LTE
Neighbor Cell Relation List and Measured Cell Identity Management in LTE
Abstract—Radio network management simplification concerns to
some extent the removal, not the simplification, of tasks. In this
paper we present an approach for automatic network
management in 3G Long Term Evolution (LTE), namely,
methods for automatic configuration of locally-unique physical
cell identities and neighbor cell relation lists. We show that these
issues can be removed from the list of planning tasks and
completely replaced by autonomous algorithms. These
algorithms make use of mobile measurements to detect local cell
identity conflicts, resolve them, and to update the neighbor cell
relation lists in the cells. The performance of the approach is
determined using simulations of realistically deployed macro
networks. The simulations illustrate the ability of the algorithms
to resolve local cell identity conflicts. In particular, the
algorithms are capable of both accommodating new cells and
handling a worst case scenario where all cells are initiated with
the same local cell identities and where neighbor cell relation lists
are empty. The contributions in this paper are meant to aid
operators by allowing them to replace time consuming and costly
tasks with automatic mechanisms, thus, reducing operational
expenditure.
