Description

Apparatus and method for providing intelligent network service

The present invention relates to an apparatus and method for providing an intelligent network service, and more particularly, to providing an intelligent network service in a wideband code division multiple access (WCDMA) network, with reference to CSI (CAMEL Subscription Information), which is an attribute of an intelligent network service. An apparatus and method for providing an intelligent network service for determining a processing path according to a type of service.

An intelligent network refers to a network environment in which a new service can be applied to a mobile communication network without changing a software of a mobile switching center (MSC). That is, most of the supplementary services of the previous wired and wireless telecommunications networks were installed in the mobile telecommunications exchanges, so that the software of the mobile telecommunications exchanges had to be changed to add new services.

In this environment, each time a new service is added, the service is affected by modifying the mobile communication exchange in operation. There are problems of developing a service with different interworking standards for each communication exchange, and it is difficult to develop a new service if the mobile communication exchange manufacturer does not inform the service developer of interworking standards.In order to solve these problems, an intelligent network emerged. to be.

In addition, CAMEL, a platform that provides an environment that can be properly defined and used by mobile operators without standardizing new value-added services, has emerged. CAMEL uses mobile and intelligent agent technologies to enable roaming services in different indirect networks. To combine.

Meanwhile, when a user terminal requests an intelligent network service related to a short message service (SMS), the mobile communication exchange sends an initial DP (Detection Point) SMS to a service control point (SCP) and receives a connected SMS. Whether to send or receive the initial DP SMS and the connected SMS is determined by the presence or absence of CSI (CAMEL Subscription Information).

Here, the presence or absence of the CSI is determined according to whether the user is a subscriber of the intelligent network service. In the case of the intelligent network service related to the SMS, the initial DP SMS and the connected SMS are not required to be transmitted or received.

That is, when a user's terminal requests an intelligent network service related to SMS, the mobile communication exchange sends a MO-FORWARD SM, which is an SMS request message, to a Short Message Service Center (SMSC) without transmitting or receiving an initial DP SMS and a connected SMS. By transmitting and receiving MO_FORWARD SM ACK in response, it is possible to provide SMS intelligent network service to the user terminal.

In other words, as unnecessary data is transmitted and received only because a service request is generated by a subscriber of an intelligent network service, an appearance of an invention in which initial DP SMS and connected SMS can be determined according to the type of intelligent network service is required. .

An object of the present invention is to determine a processing path according to a type of an intelligent network service by referring to CSI (CAMEL Subscription Information), which is an attribute of an intelligent network service, in providing an intelligent network service in a WCDMA network.
