LTE QoS (Part 2) - LTE QoS Parameters (QCI, ARP, GBR, MBR and AMBR)

We will look a little bit further into LTE QoS that we discussed last time, and learn what QoS parameters are for. There are two types of EPS bearers: default and dedicated. In the LTE network, the EPS bearer QoS is controlled using the following LTE QoS parameters: ▶ Resource Type: GBR or Non-GBR ▶ QoS Parameters QCI ARP GBR MBR APN-AMBR UE-AMBR Every EPS bearer must...

LTE QoS (Part 1) - EPS Bearers and SDF

We will talk about LTE QoS this time. QoS functions provided by any network, whether wired or wireless, are all based on standards (IETF RFC, IEEE 802, 3GPP TS, etc.). They may work differently using different standards depending on whether the network is wired (Ethernet/IP/MPLS) or wireless (LTE/WiBro/Wi-Fi). But, basically what the QoS is about is that traffic quality is guaranteed (i) if...

LTE GTP Tunnel (1): Today, we will talk about GTP tunnels used in the LTE network

Today, we will talk about GTP tunnels used in the LTE network. As seen in Figure (a) below, IP packets sent by an LTE device (UE) are delivered from an eNB to a P-GW through GTP tunnels. What it means is that "all IP packets that a UE sends are always delivered through an eNB to a P-GW regardless of their specified destination IP addresses (i.e., even though their destination IP addresses a...

LTE Network Architecture: Basic

Obviously, the hottest issue in mobile communication today is LTE. All three top telecommunication operators in Korea are trying hard to promote their brands, each containing the technical term "LTE" somewhere, for greater exposure of the brands to the public. So, we will briefly go over what network elements make the LTE network today. The Figure below is an illustration of an LTE Network R...
