1. A method performed by a network node for flexible bearer handling in a communications network, the method comprising:

  • acquiring packet data convergence protocol (PDCP) protocol data units (PDUs);

    encapsulating individual PDCP PDUs into individual frames at a protocol layer that is at least one protocol layer above a bottom-most protocol layer, wherein encapsulating said individual PDCP PDUs into said individual frames comprises mapping logic channel flows to network addresses, wherein each frame of said individual frames comprises a first signal radio bearer (SRB1), a second signal radio bearer (SRB2), a data radio bearer (DRB) or a combination of different bearers; and

    switching said individual frames towards a packet switched network, the switching based at least in part on identifying a type of PDCP PDU carried by each of said individual frames, wherein switching said individual frames towards the packet switched network comprises;

    forwarding said individual frames comprising the SRB1 to a radio resource control (RRC) acting-entity in the network; and

    forwarding said individual frames comprising the SRB2 to an S1-AP and non-access stratum (NAS) acting-entity in the network.
