11 The PM Subscription Handler (PMSH) is a micro service written in Python, which allows for the definition and unlocking
12 of PM subscriptions on one or more network function (NF) instances.
14 .. _Delivery: ./delivery.html
18 The PMSH allows for the definition of subscriptions on a network level, which enables the
19 configuration of PM data on a set of NF instances.
24 Config Binding Service
25 ^^^^^^^^^^^^^^^^^^^^^^
27 The PMSH interacts with the Config Binding Service to retrieve it's configuration information, including the
28 subscription information.
33 The PMSH subscribes and publishes to various DMaaP Message Router topics (See :ref:`Topics<Topics>`
34 for more information on which topics are used).
39 The PMSH interacts with A&AI to fetch data about network functions. The ``nfFilter`` is then
40 applied to this data to produce a targeted subset of NF's.
45 The PMSH will indirectly interact with Policy and CDS in order to push subscriptions to NF's. A policy will be used to
46 make a request to CDS, which will apply the subscription to the NF.
