Abstract

An apparatus and method for improving mobile-terminated call set-up performance comprises triggering an inter-radio access technology (IRAT) transition from a source cell to a target cell, remembering the deterministic timing of a plurality of paging occasions in the source cell, and using the deterministic timing for checking at least one paging channel in the source cell during transition to the target cell and before starting to monitor at least one paging channel in the target cell.

Description

technical field [0001] The present invention generally relates to apparatus and methods for the performance of mobile terminated call setup. More particularly, the present invention relates to improving the performance of mobile terminated call setup during handover between wireless systems. Background technique [0002] Mobile user equipments (UEs) typically transition from one wireless system to another depending on their mobility and availability of wireless system coverage. For example, transitions can occur between second generation (2G) and third generation (3G) wireless systems, between Long Term Evolution (LTE) and 3G wireless systems, or between LTE and Global System for Mobile Communications (GSM) wireless systems. As an example, 2G wireless systems typically provide basic digital voice and low-rate data services to user equipment (UE) over a wide coverage area. That is, 2G wireless systems typically have ubiquitous coverage. Wide coverage areas are achieved usi...
