Parameters

Destination
Message recipient identifier. Usually this is mobile phone number in fully qualified format.
Originator
Message sender identifier. Usually this is is number of the SMSC's account (a short GSM number). This parameter can also be an alphanumeric string or general phone number where permitted.
Content
The text or content of the message to be sent. The conversion of the characters transferred by parameter to the mobile infrastructure alphabet is done according to the value passed via Encoding parameter.
Encoding
Decides on the which conversion is applied to the Content parameter to convert it to the character set supported by message. Accepted values, members of EncodingEnum type:
et7BitText Message is encoded using 7-bit GSM alphabet as in [03.38] (6.2).
et8BitHexadecimal Message contains binary data encoded in hexadecimal format. Each two hexadecimal digits encode one byte of data.
etUCS2Text Message contains Unicode character string encoded according to UCS2 coding.
etISO88591 Message encoded as Latin 1 (ISO-8859-1). Support for this encoding may depend on SMSC configuration.

TimeStamps
Time of reception of the message to transfer by the SMSC. Used to identify status report returned by the SMSC. The pair TimeStamp and Destination (which uniqueness is guaranteed by the SMSC) is used to match status report with appropriate message submitted.

Returns

If the function succeeds, the return value is zero. Negative return value means Internal Error Code. Positive value means CIMD2 protocol's Error Code.

Remarks

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.

OnCimd2MessageReceived

Event triggered on message being received from the SMSC.

public delegate void cimd2MessageReceivedEvent(Object Sender, cimd2MessageReceivedEventArgs e);

Description

This event will occur both in the situation of receiving messages previously stored in the SMSC's queues as well as messages received while the component is connected to the SMSC.

Parameters

Sender

Properties

Connected

Returns information on connection state.

public bool Connected { get; }

Description

Remarks

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.

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 cimd2StatusReportReceivedEvent 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.
