    Abstract: A method for handling the joining and leaving an MBS session via a PDU session establishment or modification procedure is provided. Upon receipt of a back-off timer in the Received MBS Container IE (with the operation/decision “MBS join is rejected” or “Remove UE from the MBS session”), the UE shall associate the MBS back-off timer with the MBS session ID (e.g., TMGI).

  • Publication number: 20230217321
    Abstract: A method of handling interworking from 5G system (5GS) to 2/3G for an PDU session with a 3GPP EPS PDN leg is proposed. Upon intersystem change from S1 mode to A/Gb mode or Iu mode, for a PDN connection which was established as a user plane resource of an MA PDU session: if the SM activates a PDP context using parameters from the default EPS bearer context of the PDN connection, then the SMF can initiate a network-requested PDU session release procedure over non-3GPP access or perform a local release of the MA PDU session; the UE can perform a local release of the MA PDU session. Otherwise, the SMF can initiate a network-requested PDU session modification procedure over 5G non-3GPP access to move traffic of the MA PDU session to 5G non-3GPP access, or initiate a network-requested PDU session release procedure over non-3GPP access.

  • Publication number: 20230209654
    Abstract: A method of enhancing IP packet forwarding feature support after interworking is proposed. When a PDU session in 5GS is transferred to a PDN connection in EPS, the UE shall assume the feature is supported after inter-system change from 5GS to EPS. When a PDN connection is established in EPS, the network indicated that the feature is not supported, and the network provided 5GSM parameters for ESM/5GSM interworking for this PDN connection, then UE shall assume the feature is supported after inter-system change from EPS to 5GS, the UE shall also assume the feature is supported after inter-system change from 5GS back to EPS. The IP packet forwarding features include PS data off and local IP address in TFT.
