2. Current Status of SaMOG R12 Antonio de la Oliva

3. Solutions New SaMOG working document (TR 23.852- v1.4) focuses on providing three main functionalities: – Transport of multiple PDN connections between UE and TWAG – Multi-PDN connection control protocol – Service discovery

4. Transport between UE and TWAG Two main trends: – VLAN Tags + MAC address differentiation – PPPoE-based approach Some other solutions: – Adding new LLC/SLAC

5. PDN Connection control protocol Control of creation/remove of PDN connection Signal if it is a handover or a new attachment Service signaling (NSWO, new PDN to EPC..) Proposals: – Extend ANQP/GAS protocol – Extend SLAAC/statefull DHCP – Extend – Use PPPoE related control protocol – ICMP-based – New L2 protocol, with new ethertype

6. Service Discovery Need to know what services (IP continuity, NSWO, local breakout, multiple-PDN connections) are available in the TWAN Mostly all proposals are based on extending EAP-AKA signaling or ANQP/GAS (most prevalent EAP)

7. What can OMNIRAN do OMNIRAN needs to focus on functionality out of scope of 3GPP All previous functionality will be provided and defined by 3GPP
