Abstract:
1. A method for establishing communication sessions in mobile Internet Protocol networks, the method comprising: at a network entity that is configured to communicate with a first type of wireless access architecture and a second type of wireless access architecture, receiving a communication session request from a mobile node; at the network entity, determining a type of a communication session associated with the communication session request; and the network entity establishing the communication session between the mobile node and either the first type of wireless access architecture or the second type of wireless access architecture based on the type of the communication session, the network entity establishing the communication session between the mobile node and the first type of wireless access architecture by establishing a traffic channel between the mobile node and a mobile switching center (MSC), the network entity establishing the communication session between the mobile node and the second type of wireless access architecture if the type of the communication session is a data communication session, if the communication session request is sent from a mobile node operating according to the first type of wireless access architecture and the type of the communication session is the data communication session, then the network entity establishes the communication session between the mobile node and the second type of wireless access architecture in order to route the communication session around the MSC.
