WATM — New Access Bridge cannot distinguish between different kinds of handoff

  • Summary:

    In Terminal Initiated Handoff (section 8.3) and Access Recovery
    (section 8.4.2) the new Access Bridge needs to invoke different
    methods depending on the kind of handoff (step 4 in 8.3.2 and step 5
    in However, it is not possible for it to make this
    distinction based on the information it has received in previous steps
    of the handoff.

    Furthermore, in Network Initiated Handoff (section 8.2) the only
    distinction for the new Access Bridge is the previous invocation of
    transport_address_request. But it is possible that the terminal could
    not establish connectivity during the handoff procedure and resorted
    to another kind of handoff later. So in this case the new Access
    Bridge misidentifies this handoff as network initiated.

    The simplest way to correct this seems to be to add an element for
    handoff type into RecoveryRequestBody (section 7.2.4). This solution
    also looks quite clean.
