Constructor
lteSocket | the socket to be used to send/receive packets to/from the LTE radio interface |
s1uSocket | the socket to be used to send/receive packets to/from the S1-U interface connected with the SGW |
sgwAddress | the IPv4 address at which this eNB will be able to reach its SGW |

This method is triggered after the eNB received a S1-AP message of type E-RAB Setup Request by the MME and the RadioBearer has already been created
teid | the Tunnel Endpoint IDentifier of the S1-bearer to be setup. |
rnti | the unique ID of the UE on this eNB |
lcid | the Logical Channel ID identifying the Radio Bearer |
