Abstract: Systems and methods for user equipment (UE) for inter-device communication authorization and data sniffing in wireless communication systems are provided. A UE may communicate directly with another UE over a direct inter-device communication link when they are located in proximity. The UE may receive data sniffing related parameters corresponding to the inter-device communication link from a network entity, e.g. a mobile management entity (MME). The UE may store data exchanged over the inter-device communication link in a buffer and upload the stored data to a secure server in a network periodically or upon receiving a request from the network. Long term evolution (LTE) downlink or uplink radio resources may be used for the data exchange over the inter-device communication link.

Abstract: Systems, methods, and apparatuses for data and/or control offloading and handover in heterogeneous wireless communication networks are provided. Data and/or control packets can be offloaded to a coordinating base station while a user equipment (UE) remains associated with its serving cell. The packets are still transferred between the serving base station and the core network, and the offloaded data and/or control packets are forwarded from the serving base station to the coordinating base station for transmission to the UE. Furthermore, during a handover process, the serving base station and coordinating base station may independently schedule and send a handover command to the UE to reduce the radio link failure rate.
