Incoming SMS billing to Roaming partners
• Roaming is the ability of customers to use their mobile phones or other mobile devices outside the geographical coverage area provided by their normal network operator

• When customers travel abroad and use their phones or laptops whilst on a foreign (“visited”) network, this is known as international roaming.

• Sending and receiving SMS text messages whilst roaming abroad is called SMS roaming

• A friend sends an SMS to your mobile phone while you are roaming
• His operator’s network contacts your home network to find out where you are, and then routes the SMS to the network you are roaming on in the visited country
• The visited network delivers your friend’s SMS to your mobile phone.

• Most operators do not charge for receiving an SMS while roaming.
• The sender of the SMS also only pays the usual price as if the receiving customer were on their home network.

• Our SMS firewall is very limited in features
• We need to identify roaming partners using sender’s SMS Center GT
• Our mediation device does not output sender’s SMS Center GT
• SMS Center GT is available in raw MSC’s CDRs
• decodes raw CDRs and reports the count of SMS coming from roaming partners
• The report is used to bill roaming partners that exceed received SMS threshold
• If necessary a different threshold may be used for each partner
