Section: 4.4.10 DeNB
Content: DeNB function is described in more detail in TS 36.300[ Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 ]  [5]. DeNB provides the necessary S/P-GW functions for the operation of RNs connected to the DeNB. In order to provide the Relay Function the DeNB shall support the following P-GW functions: - IP address allocation for the UE functionality of the RN; - Downlink transport level packet mapping between the DSCP value used over S1-U of the UE (which is the SGi interface of the PDN GW function in the DeNB) and the EPS bearers with an appropriate QCI value and optionally ARP priority level value, established between the PDN GW function in the DeNB and the UE function of the RN; - Uplink transport level packet mapping between QCI value and optionally ARP priority level value, of the EPS bearers (established between the PDN GW function in the DeNB and the UE function of the RN) and the DSCP value used over S1-U of the UE (which is the SGi interface of the PDN GW function in the DeNB). In order to provide the Relay Function the DeNB shall support the following S-GW functions: - Termination the S11 session of the MME(RN). S-GW functions related to ECM-IDLE are not required. S-GW functions related to mobility management are not supported.
