When disconnecting from the GW, my device sends a WTP-Invoke class 0 transaction containing a WSP-Disconnect. The fact is the GW responds to this transaction by a WTP-Ack. In fact, I thought the WTP-Invoke Class 0 did NOT have a WTP-Ack. Could you please tell me about it ??? | |||

I guess you're talking about our gateway @ 213.48.20.10. I asked our WAP expert about this. He says he has noticed this behaviour in conjunction with the T68i. He says that this seems to be a little grey area in the spec. However, the definition of Transaction Class 0 states that it should not generate a result message in response. The definition goes on to also say that the responder does not acknowledge the message. However, if the U/P flag is set in the header, this indicates that the initiator requires an acknowledgement. In our case, if the U/P flag is set, we give precedence to the U/P flag being set, and send an acknowledgement. If the client didn't want an acknowledgement, we would expect the U/P flag to be clear. I'm not sure if that answers your question or not. -bn |
