Traffic demand increases explosively due to the developed services and it becomes the mobile network's load. One of these services, social networking, generates a large amount of traffic. To solve it, we propose a small cell offloading algorithm using social context. In the proposed algorithm, to satisfy the effective data rate maximally, we estimate the application selection probability using social...
Recently, enormous growth of mobile data traffic can be load to operator's core network. Offloading traffic is a promising solution to alleviate the load. The 3GPP proposes the offloading solutions such as local IP access (LIPA) and selected IP traffic offload (SIPTO). Based on the LIPA/SIPTO, many relate works provides the offloading procedures and schemes but it doesn't take the network condition...
Today, mobile data traffic explosively increases and it can be load to operator's core network. To reduce the load, 3GPP proposes the offloading solutions such as local IP access (LIPA) and selected IP traffic offload (SIPTO). For offloading algorithm, there are many related works based on the LIPA/SIPTO but some research works beyond the LIPA/SIPTO. However, these related works don't consider network...
The use of femtocells is one of the most interesting current issues in 3GPP LTE/LTE-Advanced (LTE-A) systems. System information (SI) aquisition is an essential process for handover (HO) to closed subscriber group (CSG) cells, (including femtocells). In this letter, we propose and analyze five serial SI acquisition schemes. Moreover, we propose a novel parallel scanning method to enhance the delay...
