Abstract
Abstract Systems and methodologies are described that facilitate paging for establishing a Voice Call Continuity (VCC)-supported voice call in a network containing access point(s) that can support packet switched (PS) voice communication, such as Voice over Internet Protocol (VoIP), and access point(s) that can support only circuit switched (CS) voice communication. Paging signals as described herein are selectively delivered, such that a desired terminal receives a single PS paging signal if located at a VoIP-capable access point and a single CS paging signal otherwise. A split paging technique is described herein, wherein PS paging signals are delivered to VoIP-capable access points and CS paging signals are delivered to non-VoIP-capable access points substantially simultaneously. Additionally, a sequential paging technique is described herein, wherein PS paging signals are delivered to VoIP-capable access points and, if no response is received from a desired terminal, CS-domain paging is conducted.
