Question: What is the primary purpose of Selected IP Traffic Offload (SIPTO) at the Local Network in E-UTRAN access?
Option 1: To provide APN-specific connectivity for all types of traffic.
Option 2: To offload dedicated bearer traffic on the PDN connection used for SIPTO.
Option 3: To enable an IP-capable UE to access a defined IP network, such as the Internet, without traversing the mobile operator's network.
Option 4: To allow the Local GW (L-GW) to modify UE-requested bearer resources.
Explanation: SIPTO at the Local Network is intended for offloading Internet traffic only, allowing an IP-capable UE to access a defined IP network without traversing the mobile operator's network. This feature enables efficient use of local networks and reduces the load on the mobile operator's network.
