Patent ID: 8755317

Claim:
A method for wireless communication, comprising: maintaining timing of a serving base station (BS) in a first radio access technology (RAT) and a BS in a second RAT; determining, based on the timing of the serving BS in the first RAT and the BS in the second RAT, an expected timing of a paging cycle in the second RAT; sending a mobile sleep request such that a sleep interval coincides with the timing of the paging cycle in the second RAT, wherein sending the mobile sleep request comprises sending the mobile sleep request when a delay from a current frame number of the first RAT to a next paging cycle in the second RAT is less than or equal to a maximum start frame number available to the first RAT; performing operations related to handover from the serving BS to a target BS in the first RAT; and taking action to ensure a sleep interval, after performing the handover operations, coincides with the timing of the paging cycle in the second RAT.
