Data is encoded for transmission to a second UE during the selected broadcast service, where the encoding is based on the provisioned security credentials.

Abstract: Systems and methods of segregating a SDF of a PDU session are described. The UE transmits a NAS message to the network. The NAS message indicates the SDF, the desired QoS, and a segregation indication that requests that the network establish a separate QoS flow for the SDF even if an existing QoS flow is able to support the specific QoS. The SMF decides whether or not to establish the separate QoS flow and updates filters in the UPF as well as providing a response to the UE containing a similar indication. The UE modifies resources related to the PDU session based on the response. The QoS is indicated as a 5QI and GBR or as a QFI of an existing QoS Flow on which the SDF is to be added if the separate QoS is not established. The QFI is in an unencrypted SDAP header of the NAS message.

Abstract: When a UE in an LTE system enters the RRC_IDLE state, only the S5/S8 EPS bearer context is retained, and the S1-U, S1-AP and radio bearers are released. These bearers have to be re-established on per UE basis when the UE returns to RRC_CONNECTED state. A number of UE applications may send small data frequently, which causes the UE to toggle between IDLE and CONNECTED states. This leads to a great deal of signaling overhead as the radio bearer and the S1-U bearer must be frequently re-established as the UE transitions between IDLE to CONNECTED states. Described herein are methods and systems that provide an always-on S1-U bearer to reduce this signaling overhead.

Abstract: Technology that allows PDN connections for a UE to be resumed efficiently after WLAN connectivity is lost and then regained are disclosed. A UE can have a multi-legged or multi-access packet-data-network (PDN) connection that is used to communicate with a WLAN and with an eNB. When WLAN connectivity is lost, the UE can send a WLAN-connectivity-loss communication to a PDN-GW via the eNB. A TWAG can also detect that the UE's WLAN connectivity has been lost and can send a suspension communication to the PDN-GW. The TWAG can also store PDN context information for the UE for a predefined period of time. When the UE regains WLAN connectivity, the UE can send a WLAN-link-control-protocol (WLCP) communication to the TWAG indicating that the UE wishes to resume one or more PDN connections that were previously suspended.
