The invention makes use of the Short Message Service (SMS) or Unstructured Supplementary Services Data (USSD) capabilities present in today's cellular networks as a means of providing call control and presence signalling and, in particular, for providing the means of effecting hand-off at least from/to the cellular domain to/from the WiFi domain. SMS and USSD were originally designed as engineering channels, but SMS has become highly popular as a service in its own right. SMS and USSD are built into all existing cellular (GSM, CDMA etc.) network and predate the current GPRS overlay. In particular, SMS and USSD can be used while a call may be active in the cellular domain, and a handset may send and receive such messages, with an additional facility which may be used by the invention of receiving acknowledgements of successful receipt of an outgoing SMS by the messaged party&#x2014;effectively a confirmation from the network. The present invention proposes to use SMS or USSD as a means of an adjunct call control and presence signalling in the cellular domain between a handset and the SIP domain.

Circuit bearer control

By providing voice recognition in a gaming environment, an IVR server may operate to revoice a player with a voice tone pitch and accent more appropriate to the player's character. This improves the quality of the illusion of the game play. Furthermore, accurate volume may be applied to particular voices dependent on their location relative to the player and the game may be controlled using voice commands.
