Abstract:
A user equipment (UE) reduces redirection failure resulting from failed paging responses and/or location area updates when a user equipment is redirected from a first radio access technology (RAT) to a second RAT in accordance with a mobile terminated (MT) call. The UE is redirected from a first RAT to a second RAT in response to receiving a page for a call. The UE searches for neighbor cells of a first cell when a first paging response failed for the first cell in the second RAT. The UE also attempts to acquire a neighbor cell. The UE sends a second paging response, with a redirection indicator, to either the first cell or the neighbor cell based on a signal quality of the first cell and a signal quality of the neighbor cell when a failure of the first paging response to the first cell occurred within a predetermined time period.
