Abstract
A method and a wireless device are provided for handling handover in a wireless network from a source cell to a target cell when the device has obtained and stored a handover configuration for at least one target cell X. Upon detecting a communication failure, the wireless device performs cell selection and initiates handover to one of the target cell(s) X when that cell was selected, by applying the stored handover configuration of the selected cell. When none of the target cell(s) X was selected in the cell selection, the wireless device initiates an RRC re-establishment procedure.
Claims11
A method performed by a wireless device when operating in a wireless network, for handling handover from a source cell to a target cell when the wireless device has obtained and stored a handover configuration for at least one target cell X, the method comprising:
- performing cell selection upon detecting a communication failure,
- determining whether the selected cell is one of the at least one target cell X for which a handover configuration has been obtained and stored;
- initiating handover to one of the at least one target cell X when that target cell was selected in said cell selection, by applying the stored handover configuration of the selected cell, and
- initiating an RRC re-establishment procedure when none of the at least one target cell X was selected in said cell selection.
A wireless device arranged to, when operating in a wireless network, handle handover from a source cell to a target cell when the wireless device has obtained and stored a handover configuration for at least one target cell X, wherein the wireless device is configured to:
- perform cell selection upon detecting a communication failure,
- determine whether the selected cell is one of the at least one target cell X for which a handover configuration has been obtained and stored,
- initiate handover to one of the at least one target cell X when that target cell was selected in said cell selection, by applying the stored handover configuration of the selected cell, and
- initiate an RRC re-establishment procedure when none of the at least one target cell X was selected in said cell selection.
