Option TPI in WTP Hi Experts, To Nokia Activ Server I sent an invoke request to download a content of size 10k with the following TPI's in it : Maximum Group = 5600 Maximum Receive Unit = 1400 Activ Server aborted the transaction saying MESSAGETOOLARGE If I don't send Maximum Receive Unit it sends me the message... My doubt is what's the use of Maximum Receive Unit when we have CLIENT SDU SIZE parameter in WSP Capabilities. I thought MRU TPI tells the gateway about the size of each segmented packet it needs to send. Does the WAP3GX supports WTP SAR... But the other gateway(Anonymous) is working fine.. Please correct me where am I going wrong.. | |||

I agree that reading the WTP spec, this seems vague. Nowhere else is the term "receive unit" explained, so it is not clear if "receive unit" applies to a single packet, or if it applies to the total multipacket content. Since "maximum group" is defaulted to 1405, and no default is specified for "maximum receive unit" ... I would assume that the specification authors intended "maximum receive unit" to apply to the total size of the multipacket content. However, I agree that this seems pointless, since Client SDU Size is specified in the WSP capabilities. Yes, WAP3GX does support WTP SAR. | |||

i think it's the size of the wtp sdu,if you set the Maximum Receive Unit = 1400 ,it same as the sdu size=1400,so the gateway abort the session by error message of sdu too large. | |||
