dicated EPS Bearer in EPS as described in Figure 2.15. The traffic that needs different treatment can be moved to that new connection. As long as that connection is open, selected traffic will flow through that connection and be treated separately from the other traffic in the original connection. The new connection has its own packet queue, and the packets that flow into that queue are also treated in first-in-first-out manner, Deploying IPv6 in 3GPP Networks PDP Context Single PDP Context, and two PDP Contexts associated as one connection Default EPS Bearer eNodeB Default EPS Bearer, and Default EPS Bearer with two dedicated bearers Figure 2.21 Relationship between PDP Contexts, and default and dedicated EPS Bearers. but separately from the previous queue. The selection, which packets go down which connection, is done based on a set filter - the Traffic Flow Template (TFT). We will describe the TFT in more detail in Section 2.5.3. If there is a need to distinguish between multiple types of traffic, multiple Secondary PDP Contexts or dedicated EPS Bearers can be opened with their own TFTs. Figure 2.21 shows the relationship between PDP Contexts, and the default and dedicated EPS Bearers. Though the concept of the PDP Contexts, and the different EPS Bearers is very similar, the session management treatment is slightly different; after activation, all related PDP Contexts are equal irrespective of whether they have been activated as Primary or Secondary PDP Contexts. If one PDP Context is deactivated, the others will survive. However, in EPS, deactivation of the default EPS Bearer will result in the deactivation of the dedicated bearers as well. Multiple Connections to Multiple Networks The Secondary PDP Context activation, or the dedicated EPS Bearer activation, will create a new connection with the same IP address as the original connection possibly with different parameters for QoS. Thus, from the IP's point of view, it still was just one link. However, both GPRS and EPS are also capable of activating connectio
