Providing for call-specific signaling for call-setup on multiple wireless communication systems via a single wireless access network is described herein. By way of example, a communication context for a mobile device can be established on a first radio access network (RAN). Additionally, call-specific signaling for a wireless session to be conducted by the mobile device over a second RAN can be conducted over the first RAN. Such signaling can be done, for instance, in preparation for an application or wireless session not supported by the first RAN. In addition, upon identifying an invitation for such an application or wireless session involving the mobile device, the mobile device can be switched to the second RAN, while session bindings on the first RAN can be maintained, ported to the second RAN, or terminated. Accordingly, the subject disclosure can reduce signaling complexity while integrating services of diverse deployments of wireless networks. |
