Method and apparatus for updating information within a communication system
摘要:
A method and apparatus is provided to update information within a first network (103) via a second network (102) when communication no longer exists with the first network. During operation the first network is accessed via a PSTN (108) message that is never answered by the first network. Based on the called number and caller-identification information, the first network updates its system information.
