Exponential growth of mobile subscribers and various application data traffic requirements cause exorbitant load in Long Term Evolution (LTE) networks. Telecom operators are considering small cells and Wi-Fi for handling this huge traffic demand. As User Equipments (UEs) are typically associated with a near-by cell (eNB), spatio-temporal variation in traffic demands makes the LTE networks suffer from...
LTE-WLAN Aggregation (LWA) at Radio Access Network (RAN) level offers better performance compared to other WLAN inter-working and offloading mechanisms due to its tighter integration. In rel.~13, 3GPP standardized an LWA architecture which works at the Packet Data Convergence Protocol (PDCP) layer of LTE eNodeB and provides packet-level steering. But this architecture provides sub-optimal...
In recent years, the boost of mobile-phones, tablets and smart devices with data-hungry applications has caused massive growth in demand of “Mobile data services” and fulfilling this demand is a very challenging task with all the available resources of cellular networks. This has brought us to the option of offloading traffic from the cellular networks to Wi-Fi networks. Offloading on Wi-Fi network...
