I am connected to a WCDMA 3G network. With the SMSC being a Huawei infoX SMS Gateway. Connection is via SMPP 3.3

When sending standard text messages everything works fine and messages get delivered to handsets. However when sending binary messages or wap push messages there is no delivery. EMS Text messages do get sent to handsets fine but appear as garbled text.

I've noticed through packet traces using ethereal that standard text messages are sent in a submit_sm packet and binary messages are sent via data_sm packets.

All submit_sm packets i send have a submit_sm_resp packet returned from the SMSC (even for text messages which i deliberately entered the wrong OA and TON to test errors)

however the Data_sm packets never receive a response from the SMSC.

Could anyone shed some light on this behavior or perhaps let me know of any tips or tricks to overcome this. (For example, a way of sending binary messages via the submit_sm instead of data_sm?)

Hi,

Are you using NowSMS to connect to the SMSC?

The reason I ask is because NowSMS only uses data_sm packets when "WDP Adaptation" is enabled. It is very possible that your service provider does not support "WDP Adaptation".

Some of the confusion might be that in the "WDP Adaptation" setting in NowSMS says that it is required for CDMA. However, WCDMA is not the same type of CDMA.

WCDMA (UMTS) is the 3G evolution of GSM/GPRS/EDGE, and it builds upon the technical foundations and standards of those protocols.

CDMA2000 is the 3G evolution of CDMA.

In order to send binary messages for WAP Push and MMS into a CDMA or CDMA2000 network, the SMSC needs to support "WDP Adaptation".

However, "WDP Adaptation" is NOT required for WCDMA.

Does that make sense? I'm just guessing, because it's not clear from your message that you are using NowSMS.

But if you are using NowSMS, the problem might be that "WDP Adaptation" is enabled, and the SMSC does not support it. And while "WDP Adaptation" is required for CDMA and CDMA2000, it is not required for WCDMA.
