Mobile Data Offloading

• is the use of complementary network technologies fir delivering data originally targeted for mobile networks
• rules triggering the mobile offloading action can be either set an end user or an operator
• Benefits for end user:
• data service cast control
• availability of higher bandwidth
• Benefits for operator:
• avoid congestion of the mobile networks
• no need of consecutive upgrade of mobile networks
• the main network technologies used for the mobile data offloading are WiFi of Femtocell.
• Access Network Discovery and Selection Function (ANDSF)
• is the most complete 3GPP approach to date for controlling offloading between 3GPP and non-3GPP access network (such as WiFi)
• the purpose of the ANDSF is to assist user devices to discover access networks in their vicinity and to provide rules to prioritize and manage connections to all networks.
