发明名称 Method and apparatus for managing handovers in a wireless network based on speed group assignments
摘要 A system that incorporates the subject disclosure may include, for example, determining a mobility speed group assignment for a mobile communication device having a radio resource control connection with a wireless network where the mobility speed group assignment is selected from among a plurality of mobility speed groups according to a speed of the mobile communication device, determining a cell size for a serving cell of the wireless network that is providing the radio resource control connection, and selecting a handover policy based on the mobility speed group assignment and the cell size. Other embodiments are disclosed.

主权项 1. A method comprising: monitoring, by a system including a processor, repeatedly for a first triggering event associated with a mobile communication device having a radio resource control connection with a serving cell of a wireless network, wherein the first triggering event comprises a path loss of the mobile communication device in the serving cell exceeding a threshold; monitoring, by the system, for a speed and an acceleration of the mobile communication device in response to detecting the first triggering event; determining, by the system, a mobility speed group assignment for the mobile communication device, wherein the mobility speed group assignment is selected from among a plurality of mobility speed groups according to the speed and the acceleration of the mobile communication device; determining, by the system, a cell size for the serving cell of the wireless network that provides the radio resource control connection; selecting, by the system, a handover policy based on the mobility speed group assignment and the cell size, wherein the handover policy includes handover parameter values; providing the handover parameter values to the mobile communication device via a dedicated signaling message; determining, by the system, a list of neighboring cells of the wireless network based on the serving cell; associating, by the system, a neighboring cell from the list of neighboring cells with a list of excluded neighboring cells; and performing, by the system, a handover from the serving cell to a target cell, wherein the target cell is not on the list of excluded neighboring cells based on the handover policy.
