-## Introduction
-__Subscription Manager__ is a basic platform service of RIC. It is responsible to serve, coordinate and manage xApps' subscriptions.
-
-Submgr acts as an anchor point for subscription related internal messaging, i.e. every xApp sends its subscription related messages to Submgr. Submgr invokes Routing Manager (Rtmgr) to create or tear down the subscription related routes, and the appropriate E2 Termination to signal the subscription related event also towards the RAN.
-
-The solution base on the [xapp-frame](https://gerrit.o-ran-sc.org/r/admin/repos/ric-plt/xapp-frame) project which provides the common HttpREST, RMR and SDL interfaces.
-
-Current implementation provides the following functionalities:
-* Handles RIC_SUB_REQ and RIC_SUB_RESP type RMR messages
-* Utilizes E2AP encoder/decoder generated by ASN1-C
-* Generates New subscription ID and forwards subscription request to E2 termination
-* Keeps maintaining the status of subscriptions
-* Receives Subscription response and sends it back to the subscriber
-* Uses SUBMGR_SEED_SN environment variable to initialize subscription ID counter
