Method and system of cell selection for a handover during coexistence of LTE FDD/TDD networks

摘要

A method and system for performing a cell selection in case of a handover during co-existence of LTE TDD/FDD networks is provided. The method includes receiving a handover message from a network along with a target cell for the handover. The method includes scanning for primary target cells, upon a failure in detecting the target cell by the User Equipment. The method includes storing the detected primary target cells in a measurement database by the UE. The UE initiates scanning on the stored primary target cells in the measurement database for performing the cell selection during the handover. Further, the UE after the performing the cell selection, sends the re-establishment request message along with the measurement database to the network.

1. A method for performing a cell selection in case of a handover from an initial cell to a target cell by a User Equipment (UE), wherein said initial cell and said target cell is one of a Time Division Duplex (TDD) cell and a Frequency Division Duplex (FDD) cell in a wireless network, said method comprising:
scanning a target cell on a target frequency indicated by said wireless network for a predefined time interval of a primary timer; detecting at least one said target cell on said target frequency; detecting at least one primary target cell on a suitable frequency after expiry of predefined time interval of a primary timer, upon a failure in detecting said at least one said target cell; storing at least one said detected primary target cell based on a priority in a measurement database; and selecting a primary target cell from at least one said stored primary target cell in said measurement database by initiating a secondary timer after expiration of said primary timer, when said primary target cell is available in said measurement database.
