As it said in chapter4 :

The C-GET operation allows an application entity to instruct another application entity to transfer stored SOP Instances to the initiating applicationentity using the C-STORE operation. Support for the C-GET service shall be agreed upon at Association establishment time by both the SCU and SCP of the C-GET in order for a C-GET operation to occur over the Association. The C-STORE Sub-operations shall be accomplished on the same Association as the C-GET operation. Hence, the SCP of the Query/Retrieve Service Class serves as the SCU of the Storage Service Class.

My question:
how to use the same association accomplish the C-Store Sub-operations??????
how to start a new C-STORE Sub-operation with the same association??????

My code:
OFCondition DcmSCP::handleGetRequest(T_DIMSE_C_GetRQ &reqMessage,
                             const T_ASC_PresentationContextID presID)
   OFString tempStr;
   // Dump debug information
   if (DCM_dcmnetLogger.isEnabledFor(OFLogger::DEBUG_LOG_LEVEL))
      DCMNET_INFO("Received C-Get Request");
      DCMNET_DEBUG(DIMSE_dumpMessage(tempStr, reqMessage, DIMSE_INCOMING, NULL, presID));
      DCMNET_INFO("Sending C-Get Response");
   } else {
      DCMNET_INFO("Received C-Get Request (MsgID " << reqMessage.MessageID << ")");
      DCMNET_INFO("Sending C-Get Response (" << DU_cechoStatusString(STATUS_Success) << ")");

   //// intialize some variables
   //GetCallbackData callbackData;
   //callbackData.assoc = m_assoc;
   //callbackData.imageFileName = "aaaa.DCM";
   //DcmFileFormat dcmff;
   //callbackData.dcmff = &dcmff;
   //callbackData.presID = presID;
   void * callbackData = NULL;
   OFCondition cond = DIMSE_getProvider(m_assoc,presID,&reqMessage,getProviderCallback, callbackData, DIMSE_BLOCKING,5);
   return cond;

void DcmSCP::getProviderCallback(
   /* in */
   void *callbackData,
   OFBool cancelled, T_DIMSE_C_GetRQ *request,
   DcmDataset *requestIdentifiers, int responseCount,
   /* out */
   T_DIMSE_C_GetRSP *response,
   DcmDataset **responseIdentifiers,
   DcmDataset **statusDetail)

   OFString queryRetrieveLevel;
   OFString patientId;
   OFString studyInstanceUID;
   OFString seriesInstanceUID;
   OFString sopInstanceUID;

   OFCondition result = requestIdentifiers->findAndGetOFStringArray(DCM_QueryRetrieveLevel,queryRetrieveLevel);
   result = requestIdentifiers->findAndGetOFStringArray(DCM_StudyInstanceUID,studyInstanceUID);
   result = requestIdentifiers->findAndGetOFStringArray(DCM_SeriesInstanceUID,seriesInstanceUID);
   result = requestIdentifiers->findAndGetOFStringArray(DCM_SOPInstanceUID,sopInstanceUID);

   //OFList<OFString> ts;
   //OFCondition m1 = storeSCU.addPresentationContext(UID_DICOS_CTImageStorage, ts);

   T_ASC_PresentationContextID presID = findPresentationContextID(UID_DICOS_CTImageStorage,UID_LittleEndianExplicitTransferSyntax);
   OFString dcmFileName = "aaaa.DCM";
   DcmDataset dataset;
   Uint16 rspStatusCode;
   sendSTORERequest(presID, dcmFileName, &dataset, rspStatusCode);

Thanks for your help.
