  • Publication number: 20240163721
    Abstract: Embodiments of this application provide an information indication method and apparatus. The method includes: A CP indicates, to a UP by using first information, a maximum number of EHC contexts that can be established by the UP for UE, a DRB of the UE, or a PDU session of the UE in a downlink direction, so that the UP can establish a proper number of EHC contexts for the UE, the DRB of the UE, or the PDU session of the UE in the downlink direction based on the maximum number. This resolves a problem that a UP in an access network device in a split architecture cannot establish a proper number of EHC contexts for the UE because the UP does not know a capability of the UE.
