sms - EasySMPP API を使用して連結 SMS メッセージを送信する (UDH 情報を追加する方法)

Question

私は EasySMPP と呼ばれる c# API を使用しています。単一の SMS を送信するのには非常に優れています。大きな SMS を送信するのにも適していますが、受信者はメッセージを個別に取得します。これは意味がありません。私が探しているのは、PDU を変更する方法です。 UDH情報を追加できること。

UHD 情報を追加するにはどうすればよいですか。API の SubmitSM メソッドは次のとおりです。

public int SubmitSM
(
byte sourceAddressTon, 
byte sourceAddressNpi, 
string sourceAddress,
byte destinationAddressTon,
byte destinationAddressNpi, 
destinationAddress, 
byte esmClass, 
byte protocolId,
byte priorityFlag, 
DateTime sheduleDeliveryTime, 
DateTime validityPeriod, 
byte registeredDelivery,
byte replaceIfPresentFlag,
byte dataCoding,
byte smDefaultMsgId,
byte[] message)

 {
 try
 {

                byte[] _destination_addr;
                byte[] _source_addr;
                byte[] _SUBMIT_SM_PDU;
                byte[] _shedule_delivery_time;
                byte[] _validity_period;
                int _sequence_number;
                int pos;
                byte _sm_length;

                _SUBMIT_SM_PDU = new byte[KernelParameters.MaxPduSize];

                ////////////////////////////////////////////////////////////////////////////////////////////////
