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.

CDMA intelligent network system and its method, device for realizing international roaming service

Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.

The present invention discloses a system and method for implementing prepaid data services in a mobile communication network. In this system, a Data service Access Control Point (DACP), which is used for fulfilling price confirmation function and fee application function for data services, is added between a Service Control Point (SCP) storing prepaid account information of subscribers and a Prepaid Server/Content of Process Gateway (PPS/CP GW) used for data service charging. In the method of the present invention, by means of the interaction among a Packet Data Service Note (PDSN), a Home Authentication Authorization and Accounting (HAAA) server, the PPS/CP GW, the DACP and the SCP, the SCP deducts the fees from the prepaid account, and the PDSN controls the subscriber to utilize data service according to the fees deducted by the SCP. With the present invention, the subscriber can make prepayment for a data service by a prepaid voice account, which facilitates data service extension of mobile network operators and provides convenient data services for the subscribers.

System and method for implementing prepaid data services

The present invention discloses a method for providing a Virtual Private Network (VPN) service. The method comprises the steps of: after receiving a call request from a user terminal, a Service Control Point (SCP) judging whether the user terminal has applied for a prepaid service at the same time, if so, initiating a VPN service logic, invoking a prepaid service logic by the VPN service logic, and deducting fee from a prepaid account corresponding to the user terminal while providing the VPN service to the user terminal. With the present invention, a VPN service can be provided for a prepaid service user, which not only brings convenience for prepaid service users, but also prompts expansion of VPN service, thus bringing great interests for the operators.
