WWAN_SMS_SEND_PDU structure (wwan.h)

The WWAN_SMS_SEND_PDU structure represents a PDU-style SMS message.

Syntax

typedef struct _WWAN_SMS_SEND_PDU {
  BYTE Size;
  CHAR PduData[WWAN_SMS_PDU_HEX_BUF_LEN];
} WWAN_SMS_SEND_PDU, *PWWAN_SMS_SEND_PDU;

Members

Size

For GSM-based devices that support PDU-style SMS messages, the size, in bytes, of the message before conversion to hexadecimal.

For CDMA-based devices that support sending SMS messages in binary format, the size, in bytes, of the message in PduData .

The following table lists the different values for the SmsFormat member of the WWAN_SMS_SEND structure and their corresponding range that is allowed in this member.

SmsFormat	Size
WwanSmsFormatPdu	1 to WWAN_SMS_RAW_PDU_LEN
WwanSmsFormatCdma	1 to WWAN_SMS_CDMA_MAX_MSG_LEN

 

Note  For GSM-based devices, if ElementType is set to WwanStructSmsPdu, this member describes the size, in bytes, of PduData excluding the Service Center address. The first byte of PduData represents the size of the Service Center address that the miniport driver must add when it calculates the exact size of the PduData buffer.

For example:

If PduData [0] = 0, then the size of PduData is Size + 1.

If PduData [0] != 0, then the size of PduData is Size + PduData [0].

 

PduData[WWAN_SMS_PDU_HEX_BUF_LEN]

A NULL-terminated string that represents the content of the record.

For GSM-based devices, the contents are coded in a hexadecimal string format (according to the 3GPP TS 27.005 and 3GPP TS 23.040 standards) that represents the SMS text message.

For CDMA-based devices that support sending SMS messages in binary format (that is, miniport drivers that return WWAN_SMS_CAPS_PDU_SEND in the WwanSmsCaps member of WWAN_DEVICE_CAPS), PduData contains the SMS message as a byte array, as defined in section 3.4.2.1 SMS Point-to-Point Message in the 3GPP2 specification C.S0015-A "Short Message Service (SMS) for Wideband Spread Spectrum Systems". SMS will only support Wireless Messaging Teleservice (WMT) format. Miniport drivers should typecast this information to BYTE[] for CDMA-based devices. It is not coded in hexadecimal string format.
