Abstract: The present invention discloses a method, an apparatus and a system for service association based on service nesting charging. Wherein the method for service association based on the service nesting charging includes: obtaining a request message sent from a service platform, wherein the request message carries key service information; searching in stored service record information for the service record information which matches the key service information, wherein if matched service record information exists, then a charging identifier in the matched service record information is obtained, and if no matched service record information exists, then a charging identifier is allocated, said charging identifier being used for performing an association charging on multiple services which have the same charging identifier by a charging platform; sending the charging identifier and the information carried in the request message to a receiving end of the request message.

Abstract: The present invention discloses a CDMA intelligent network system and a method for implementing an international roaming service. The CDMA intelligent network system includes: a Home SCP, a Home Gateway Mobile Switching Center (GMSC) or Home International Switching Center (ISC), and a visited GMSC or visited ISC; further, the CDMA intelligent network system includes a roaming SSP. The SCP is in communication with the roaming SSP, and voice channels are established among the roaming SSP, the Home GMSC or ISC, and the visited GMSC or ISC. The present invention further discloses a roaming Service Switching Point, which is adapted for signaling exchanging with the Home SCP of subscriber in international roaming, so as to establish a service route for the subscriber in international roaming in the CDMA intelligent network.
