FIELD: information technology. ^ SUBSTANCE: mobile station which is configured to facilitate coordination of supplementary services using a centralised method may include circuit-switched (CS) domain components which are configured to place voice telephone calls in a CS domain. The mobile station may also include IP multimedia subsystem (IMS) components which are configured to place voice telephone calls in an IMS domain. The IMS components may include a transport component for facilitating communication with an IMS core network. The IMS components may also include a signalling component which is configured to exchange information with a centralised server on the IMS core network via the transport component. At least some of the information which is exchanged with the centralised server may be related to supplementary services for the voice telephone calls in the CS domain as well as the voice telephone calls in the IMS domain. ^ EFFECT: seamless transition between networks and/or protocols for optimising and converging on the best communication protocol for the user. ^ 29 cl, 12 dwg |
