+/*State transition. Will be triggered when there TStarted message is received from the lower layers.
+This transition will trigger the request/response mechanism to retrieve bearer type from lower layer.
+New Parameter set is added to Parameter bundle and passed to service Provider from IPCPR.
+Agent CPR/PDP CPR will update the parameter with the bearer type and send it back to IPCPR.
+IPCPR will extract the TCP receive window from the lookup table at NetMCPR after it receives the 
+bearer type and send it to IPSCPR(ie. the dataclients)
+
+TInitialiseParamsAndSendToSelf will initialise the parameter bundle at IPCPR and send to self.
+SendToSelf will start a mechanism ato send the bundle to the service providers below.
+
+The message is recd. ate the Agent/PDP CPR and the bundle is updated with the bearer type.
+Respons with retrieved params sends a response to the IPCPR.
