Abstract: An architecture, for a cellular communications system, is described herein in which a “bearer-less” model is used for both the radio interface and the network core. Instead of using an individual Layer 2 bearer for each Quality of Service (QoS) class, in the architecture described herein, a common Layer 2 connection (e.g., a Layer 2 “fat pipe”) may be used to handle traffic flows between a User Equipment (UE) device and an external Packet Data Network (PDN). Additionally, a bearer-less architecture may be used in the radio interface (i.e., between User Equipment (UE) and the eNB).

Abstract: The techniques introduced here provide for network assisted device-to-device communication for peer-to-peer applications. The techniques include registering a user's peer-to-peer application identifier with a peer-to-peer application server, registering a peer-to-peer application with a device-to-device server, sending a peer-to-peer service request to the peer-to-peer application server, and receiving network assistance in discovering a peer with the desired P2P content/service and establishing a device-to-device communication arrangement for exchange of peer-to-peer services.
