1  Scopep. 6

The present document studies the additional UE - EPC procedures within the scope of TS 24.302 and TS 24.229, for the interworking between a 3GPP system and a Fixed Broadband Access network defined by Broadband Forum to provide the IP connectivity to a 3GPP UE using a WLAN and a H(e)NB connected to a Fixed Broadband Access network.
The report covers the discovery and network selection procedures, QoS aspects, Tunnel management procedures, selection of the IP mobility mode, Authentication and Access Authorization using Authentication, Authorization and Accounting (AAA) procedures, and IP CAN session impacts.
The present document is applicable to the UE and the network. In this technical specification the network is the 3GPP EPC.
