Abstract: Technology for reducing buffer overflow at a Third Generation Partnership Project (3GPP) Serving Gateway (S-GW) is described. A buffer overflow message may be received, at an evolved node B (eNB) from the S-GW, indicating potential overflow of downlink information at an S-GW buffer. The downlink information may be stored at the S-GW buffer until a plurality of user equipments (UEs) awake from a low power mode during a discontinuous reception (DRX) sleep cycle. One or more UEs may be selected from the plurality of UEs according to predefined criteria, wherein the one or more UEs are in a connected mode. The DRX configurations of the one or more UEs may be modified in order to reduce the downlink information that is stored at the S-GW buffer, thereby reducing the potential for overflow at the S-GW buffer.

Abstract: Technology for mitigating traffic congestion is disclosed. A master evolved node B (MeNB) can identify service data unit (SDU) packets that are dropped in a retransmission buffer of a packet data convergence protocol (PDCP) layer of the MeNB. The MeNB can create a list of packet data unit (PDU) packets that are dropped at the PDCP layer of the MeNB, wherein the PDU packets that are dropped are associated with the SDU packets. The MeNB can send the list of dropped PDU packets, from the PDCP layer of the MeNB to the PDCP layer of a user equipment (UE), to enable the UE to distinguish between delayed PDU packets and the dropped PDU packets.

Abstract: Technology for reducing packet transmissions is disclosed. A master evolved node B (MeNB) configured for dual connectivity can receive one or more acknowledgements (ACKs) from a user equipment (UE) indicating packets that were successfully received at the UE from a secondary evolved node B (SeNB). The MeNB can receive, from the SeNB, packet delivery information for the SeNB. The MeNB can receive an indication from the SeNB of an air-interface connection loss between the SeNB and the UE. The MeNB can identify remaining packets that were not sent from the SeNB to the UE based, in part, on the ACKs received from the UE and the packet delivery information received from the SeNB, wherein the remaining packets are not sent to the UE due to the connection loss between the SeNB and the UE. The MeNB can send the remaining packets from the MeNB to the UE.

Abstract: Embodiments of an enhanced Node B (eNB) and method for RRC connection establishment for small-data transfers in a 3GPP LTE network are generally described herein. The eNB may receive a small-data RRC connection request message from user equipment (UE) that may include an establishment clause value indicating small-data traffic either with or without mobility. The eNB may send an initial UE setup request message to inform the mobility management entity (MME) that a small-data RRC connection is being established. The eNB may receive an acceptance message from the MME for the small-data RRC connection which may include a reduction of an RRC inactivity timer for fast connection release. The eNB may send an RRC connection reconfiguration message to the UE in response to receipt of the acceptance to establish the small-data RRC connection, the RRC connection reconfiguration message including a measurement information element (IE) when mobility is to be supported.

Abstract: Technology for communicating data to a user equipment (UE) is disclosed. Effective data rates may be identified, at a master evolved node B (MeNB), for the UE with respect to the MeNB and a secondary evolved node B (SeNB). A downlink split ratio for bearers of the MeNB and the SeNB to the UE may be determined based in part on the effective data rates for the UE. A first portion of data may be sent from the MeNB to the UE according to the downlink split ratio. A remaining portion of data may be sent from the MeNB to the UE via the SeNB according to the downlink split ratio, wherein the UE supports dual connectivity with the MeNB and the SeNB.
