Method of handling cell change and related apparatus

摘要

A communication device of handling cell change for a mobile device includes performing a cell change order procedure from a source cell of a first radio access technology to a target cell of a second radio access technology, establishing a returning condition corresponding to access barring of the target cell, and determining that the cell change order procedure is failed when the returning condition is conformed.

主权项

1. A method of handling cell change for a mobile device, the method comprising:
receiving a first cell change order message from a source cell of a first radio access technology; in response to the receiving, performing a cell change order procedure from the source cell of the first radio access technology to a target cell of a second radio access technology; receiving a message indicating the access barring of the target cell of the second radio access technology from the target cell of the second radio access technology; determining that the cell change order procedure is failed when the message is received; selecting to the source cell after determining that the cell change order procedure is failed; sending a cell change order failure message to the source cell, wherein the cell change order failure message includes failure information indicating that the failure of the cell change order procedure is caused by access barring; and receiving a second cell change order message in which whose failure information includes an access barring time from the source cell for re-performing the cell change order procedure, wherein the second cell change order message is received after the access barring time elapses.
