Abstract: An instant messaging service is provided using short message service (SMS) messages as the underlying transport layer. A user having a phone associated with an MSISDN can use a client to generate messages that are then transmitted as if they originated from the phone. The SMS message is delivered to the second party's phone as per a normal SMS message. If the second party is also using a client, the client can retrieve messages addressed to the second party's MSISDN even though client does not need to be associated with the MSISDN. The use of SMS messages provides for a persistent and reliable transport layer, and also allows for fall back to SMS messaging for either party independently.

Abstract: A method and apparatus for charging control of service usage in an electronic communications system. An invocation of charging control is received from a service client for service usage by a user. Charging related data and rules checked for the user and it is determined whether the session should be charging controlled. In case of a non charging controlled session, a response message is returned to the charging client, indicating that the session is not charging controlled and that the service usage is to be reported at the end-of-session. A report of usage is received—from the client—including information of the usage consumed during the session at the end-of-session.
