Events

OnTcpDisconnected

Event triggered on disconnection on network protocol (TCP/IP) level.

public delegate void tcpDisconnectedEvent(Object Sender, tcpDisconnectedEventArgs e);

Description

The event informs about the tear down of connection between the component and the SMSC on the network layer level (TCP). Such situation may be due to disconnection by SMSC (as per the rules of protocol after the timeout of inactivity of the component, in the case when connection is not kept alive) and in the case of disconnection for other reasons concerning functioning of the network layer.

Parameters

Sender

Object sending the event.

e

Object encapsulating event parameters.

int Reason
When the result is zero the connection has been disconnected by remote party. When the result is -1 then connection has been ended by the component itself, because inproperly formatted response has been received during the attempt to communicate with the remote party. Positive value means Network Error Code.

See Also

OnTcpDisconnected, tcpDisconnect

Parameters

Sender

Object sending the event.

e

Object encapsulating event parameters.

uint SequenceNumber
Identifier of the request/response sequence exchanged between SMPP client and server. Response should have the same Sequence Number as request. Sequence Numbers are generated independently by client and server and should be unique for each peer.

This field identifies type of particular SMPP message which indicates what operation data is contained within Protocol Data Unit (PDU).
int CommandStatus
Indicates the success or failure of an SMPP request. It is relevant only in the SMPP response message. Takes values as per the protocol documentation SMPP (5.2.28). The full list of the error codes is provided in the chapter Error Codes at the end of this manual.

Integer value denoting Type Of Number.
int ONPI
Integer value denoting Numbering Plan Identifier.
string Content
This can be ASCII characters string or hexadecimally encoded binary content. This value should be interpreted according to the value of Encoding parameter.
EncodingEnum Encoding
Possible values as per EncodingEnum type definition.
string UserDataHeader
If the message received contains the User Data Header (UDH), it will be returned in this field as hexadecimally encoded binary content, for example: "06050415831583". If the message does not have UDH empty string is returned.

Example

smpp.tlv.its_session_info=00E1

Properties

Connected

Returns information on connection state.

public bool Connected { get; }

Description

If property is true then connection state on TCP/IP level is connected. If property is false then connection has been disconnected on TCP/IP level. Property is useful in implementing various reconnect scenarios.

tcpConnect, tcpDisconnect

KeepAliveInterval

Connection keep-alive timing.

public int KeepAliveInterval { get; set; }

Description

Value in seconds denoting time interval between packages keeping the connection alive in case no other packages are exchanged with the SMSC. It should be set according to the SMSC operator's instructions and the speed of Internet connection between the component and the SMSC. Typically, this value amounts to one third of the time after which the SMSC breaks the connection in case of lack of activity. When set to zero keep alive packets are never sent to the SMSC.

ResponseTimeOut

Communication timeout.

public int ResponseTimeOut { get; set; }

Description

Time in seconds, which determines maximum time the component will wait for response from the SMSC. It concerns all protocol level functions. After this time the function returns error code denoting operation timeout.

ImmediateResponse

Status report confirmation mode.

public bool ImmediateResponse { get; set; }

Description

Property decides whether OnSmppStatusReportReceived event confirms receive of the status report to the SMSC before (true) or after (false) execution of user code in the event handler. If the report is confirmed before SMSC may initiate another status report delivery faster. Contrarywise in the report is confirmed after, if user code inside event fails the status report is not confirmed and will be repeated by the SMSC within some time.

ThrottleRate

Message throttling limit parameter.

public int ThrottleRate { get; set; }

Description

Determines maximum rate of messages submitted to the SMSC per second. If set to any value above 0 component counts number of messages submitted and limits the rate by waiting appropriate time inside smppSubmitMessage, smppSubmitMessageEx, smppSubmitMessageAsync and smppSubmitData functions. If the value is set to zero component does not limit the rate of messages submitted.
