Ericsson Announces Integrated Wireless Network, her tool switches to wifi-cellular networks
The majority of manufacturers have the solution to their catalog: offload some of the data traffic of cellular networks to Wi-Fi networks in dense areas covered by minicells (Pico, Metro, etc..). The manufacturer Ericsson has presented his in MWC 2012: Integrated Wi-Fi Network The transition from one network to another should be transparent to the user and work with any device, without additional software.
The roaming agreements obligatory
When a terminal 3G and Wi-Fi between this hot spot 2.0, will be detected by the access point and his identification information (from, for example, the SIM card) back to the authentication module will relay them to the HLR of the mobile operator, if the operator in question is the same as the spot hopt, or has entered into roaming agreements. In this case, the terminal is in connection with the Service Router (SSR 8020 at Ericsson) that manages the hot spot. This one interrogates the Policy Manager on which it is connected for the type of service that the subscriber is entitled. The router also attributed a different IP address (most terminals only support one IP address) and setup a GTP tunnel (GPRS Tunnel Protocol) network to the heart of the cellular network operator, since the data is not unlike the voice, processed by the local operator.
