<edit> hmmm - seems to be a problem with the above link - try this one instead : http://www.mobilemarketingwatch.com/ibm-creates-sms-spam-solution-for-china-mobile-accused-of-censorship-5863/ </edit>
I spotted this article this morning - I don't know much about it yet, but I will try to find out some more over the next week or so. I would however note the section of the article that states:
"... In its defense, IBM claims all its solution will do is identify and block large sources of SPAM SMS- not scan every single message to see if it’s in accordance with the Chinese Government’s guidelines...."
I know that some Telcos that I have worked with have what they call "Anti-SPAM" servers on their network. The key difference between those and this new one at China Mobile is that this new solution looks to be part of the mobile to mobile SMS traffic whereas other that I have seen are all about mobile originated traffic to shortcodes (for application traffic). This has become a problem for some telcos who offer unlimited (or close to unlimited) SMS plans. Existing systems that I know of simply count the number of SMS's sent by that MSISDN (phone number) to a particular shortcode - if it exceeds 50 within a 24 hour period, simply drop the messages. Those systems present an interesting conundrum for SMS voting and SMS competition entries. A subscriber thinks they have entered/voted (say) 200 times by sending 200 short messages, but the actual count that the application (the voting or the competition entry database) is only 50 for that 24 hour period. If we're talking about unlimited SMS plans, there is no real penalty to the subscriber other than their perceived votes/entries won't be as high as they thought. But for mobile plans that are paying for each SMS sent, the subscriber is not getting what they pay for... I can understand why a subscriber of a pay as you consume mobile plan would be very upset with their messages getting dropped, not that a true SPAMer would ever use a mobile phone plan like that.
