Patent ID: 7600009

Claim:
A system, comprising: a network having a first network access point and a second network access point and configured to carry data between the first network access point and the second access point using a packet-switched bearer and a circuit-switched bearer; and a first terminal configured to connect to the first network access point and a second terminal configured to connect to the second network access point, each terminal being configured to support simultaneously a connection of a first bearer type and a connection of a second bearer type with the other terminal via the network as a single logical communication arrangement, wherein the first bearer type is a packet-switched bearer and the second bearer type is a circuit-switched bearer or vice versa, wherein the connection of the first bearer type is configured to be established at the commencement of communication between the terminals using addresses of the first bearer type of the respective terminals, and the connection of the second bearer type is configured to be subsequently established between the terminals when a new type of data is introduced into the communication, transmission of which is better supported by a connection of the second bearer type, wherein each terminal is configured to establish the connection of the second bearer type using an address of the second bearer type of the other terminal, and wherein the addresses of the first bearer type of the respective terminals are different from the addresses of the second bearer type of the respective terminals.
