Abstract

Certain embodiments of the present disclosure provide a method for communicating, by a multi-mode mobile station (MS), with first and second networks via first and second radio access technologies (RATs). The method generally includes determining a first set of one or more paging parameters in an effort to establish a listening interval of a sleep cycle of the first network that aligns with a sleep interval of a control channel cycle of the second network and communicating the first set of paging parameters to a base station of the first network in a request to establish the sleep cycle of the first network.
