ENHANCING CELLULAR NETWORKS VIA AN ADJUSTABLE HANDOVER BOUNDARY
First Claim
1. A method for handing off handset in a mobile communication network comprising:
- defining at a base station an adjusted handover boundary different from a default handover boundary between the base station and a different base station; and
conveying handover adjustment parameters within messages to user equipment (UE) within range of the base station, wherein the handover adjustment parameters provide specifics for handover permitting the user equipment (UE) receiving the messages to perform handover operations in accordance with the adjusted handover boundary instead of the default handover boundary.

Abstract
A method for handing off handset in a mobile communication network that defines at a base station (110) an adjusted handover boundary (106) different from a default handover boundary (104) between the base station (110) and a different base station (116). Handover adjustment parameters can be conveyed (120) within messages to user equipment (UE) (112) within range (124) of the base station. The handover adjustment parameters can provide specifics for handover permitting the user equipment (UE) (120) receiving the messages to perform handover operations (166) in accordance with the adjusted handover boundary (106) instead of the default handover boundary (104). The handover adjustment parameters can increment the cell individual offset (CIO) (212) when adjusting for “too late” (210) handover conditions. The handover adjustment parameters decrease the cell individual offset (CIO) (222) when adjusting for “too early” (220) handover conditions.

12. A base station node (eNodeB) of a long term evolution (LTE) of a mobile telecommunication system comprising:
-
at least one transmitter for wirelessly transmitting digitally encoded content to user equipment (UE) via radio frequency signals over the long term evolution (LTE) compliant network; at least one receiver for wirelessly receiving digitally encoded content from user equipment (UE) via radio frequency signals over the long term evolution (LTE) compliant network; and computer program instructions digitally encoded in at least one storage medium, wherein the computer program instructions implement a self-organizing network (SON) automatic neighbor relationship (ANR) function to resolve a cell individual offset oscillation. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for detecting handover resolution conflicts comprising:
-
triggering a set of user equipment (UE) within radio frequency range of a base station node to determine neighbor base station nodes also in radio frequency range of the corresponding user equipment, wherein the base station node performs the triggering, wherein the base station node is a long term evolution (LTE) cell of wireless mobile telecommunication system configured to periodically sample a set of user equipment configured to measure the cell-offset of the neighbor base station nodes; receiving at the base station node responses from the set of user equipment and detecting a handover resolution failure based on the cell-offset. - View Dependent Claims (20)
