Methods and systems for optimizing short data burst services over an LTE network

摘要

Methods and related systems for managing wireless network capacity in support of short data burst (SDB) services over long term evolution (LTE)-based networks are provided. Such methods and systems provide improved efficiency and performance, thereby increasing the capacity of LTE-based networks to support SDB services.

主权项

1. A method for supporting short data burst (SDB) services, the method comprising:
receiving a radio resource control (RRC) connection request message comprising a mobile originated (MO), SDB indicator, at an evolved node (eNB) from user equipment (UE) over a signaling radio bearer channel; transmitting an RRC connection set-up message from the eNB to the UE in response to the RRC connection request message; receiving an RRC connection set-up complete message comprising an uplink, non-access stratum (NAS) message that further comprises MO SDB content and the MO SDB indicator at the eNB from the UE; forwarding the NAS message with the MO SDB content and indicator and an initial UE message from the eNB to a mobility management entity (MME); receiving an initial context set-up request message containing an MO SDB indicator flag at the eNB from the MME; sending a RRC connection release message from the eNB to the UE; and sending a UE context release request message comprising an SDB delivery indicator from the eNB to the MME.
