FIELD: radio engineering, communication.SUBSTANCE: communication system also includes a gateway which maps massages between a packet switched network and at least one channel switched network. The gateway may support communication between a first terminal and a second terminal such that the first terminal has a packet switched connection with the gateway and the second terminal has a channel switched connection with the gateway. The first terminal may then establish a channel switched connection with the gateway. Further, the gateway may link the channel switched connection established between the first terminal and the gateway and the channel switched connection between the gateway and the second terminal.EFFECT: enabling channel switching without interruptions so that a call can be switched such that communication terminals are not aware of the switching or do not have to take any specific action to perform said switching.13 cl, 4 dwg |
