Quality of USSD is influenced by many factors. When we supply a client with a USSD service we have to take into account the consumers handset, the networks towers, the networks load, our servers and of course our clients servers.
USSD sessions can remain open until timed out and this causes a lot of headaches at all levels. Its the technology and not the infrastructure thats the problem - so stop moaning.
Ok.
What telecom do you represent and what TC technology standard do you mean ?
USSD service is highly reliable in cell phone.
Problems are with USSD service for cellular modem.
Technology is neither complicated not new or modern.
Already in operation in the last 10 years.
In case of network overload, USSD response is simply delayed, that's all.
There are many other ways to transmit and request USSD.
Any 3G HSDPA service must be reliable and especially service like
account balance management with balance check USSD commands.
It's a legal not technical problem, if my telecom is legally obliged under
end-user contract, under ITU Regulations
International Telecommunication Regulations (ITRs)
http://www.itu.int/ITU-T/itr/
under
International Telecommunication Convention
http://openlibrary.org/b/OL2420433M
to provide end-users with quality service, set by the above Regulations and Convention and local acts, regulations, rules.
======
my search for USSD term at website of the ITU generated the following list, so you can see USSD is an official standard, not option in Telecom World.
I have already contacted ITU's General Secretariat
and expect to get more details about USSD telecom contract service
in due time .
I would like to know if not sending Operator's name (set to UNKNOWN) for MDMA application is in a violation of the above named Convention or not.
It is really not common not to have my operator's name displayed on LCD of my cell phone.
In case of cellular modem and MDMA application, such service is downgraded by my Telecom.
