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.

- receiving a radio resource control (RRC) connection request message 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;
- receiving an RRC connection set-up complete message comprising an uplink, non-access stratum (NAS) message that further comprises SDB content at the eNB from the UE;
- forwarding the NAS message with the SDB content from the eNB to a mobility management entity (MME);
- and
- receiving a UE context release command message containing an SDB delivery indicator from the MME at the eNB.
A system for managing the capacity of a long term evolution (LTE) network to support short data burst (SDB) services comprising:
- an evolved node (eNB) operable to,
- receive a radio resource control (RRC) connection request message comprising a mobile originated (MO), SDB indicator from user equipment (UE) over a signaling radio bearer channel;
- transmit an RRC connection set-up message to the UE;
- receive 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 from the UE;
- forward the NAS message with the MO SDB content and indicator and an initial UE message to a mobility management entity (MME);
- receive an initial context set-up request message containing an MO SDB indicator flag from the MME;
- send a RRC connection release message to the UE;
- and
- send a UE context release request message comprising an SDB delivery indicator to the MME.
