Description

Call waiting service in wired communication system {CALL WAITING SOUND SERVICE METHOD FOR WIRE COMMUNICATION SYSTEM}

1 is an exemplary view showing a call waiting sound service process in a conventional wired communication system.

Figure 2 is an exemplary view showing a call waiting sound service process in a wired communication system according to the present invention.

The present invention relates to a call waiting service method in a wired communication system. In particular, the announcement broadcasting module and the music sending module are built in a switching system to manage a call waiting service subscriber for each switching system. The present invention relates to a call waiting service method in a wired communication system, which can maximize the capacity of a call waiting service subscriber and the capacity of simultaneous call processing while not departing from the call processing method.

In general, a conventional landline telephone system outputs a ring back tone when a telephone call is made. However, in a mobile communication system, a coloring service is used to transmit a music selected by a subscriber instead of a ring back tone (call waiting service). It is implemented.

Of course, the wired service provider is also implementing the service applying this, but due to the technical limitations of the wired service network, it is provided in an inefficient manner such that a lot of resources are consumed to provide such a service.

For example, a call waiting sound service in a landline telephone is currently provided to a subscriber using an intelligent network scheme. As shown in FIG. 1, if triggering occurs by determining whether an intelligent network subscriber is present in a subscriber call processing block, SCP (Service control point) Determines whether the subscriber is a call waiting tone service, requests a routing to IP (Intelligent Peripheral) in case of call waiting tone subscriber, and the SSP (Service Switching Point) controls the SCP to route the call to IP to the caller. Call Waiting Sound Service Subscriber (receiving subscriber) sends out a pre-selected call waiting sound.

Then, when the called subscriber answers the phone, the connection is released from the IP side, and the caller and the called party are connected to make a call.

However, in order to provide a call waiting service in the current landline, a lot of resources are consumed internally in the exchange. That is, basic process for subscriber call processing should be created first, another process in charge of connection of IP side should be created, and relay line resources for interworking with IP and SCP are consumed. Therefore, as the call waiting sound service expands, it becomes more difficult to provide an efficient service due to the limitation of the internal system resources of the exchange.

In addition, the exchange system that cannot interwork with SCP and IP cannot provide the above-mentioned call waiting service, and even in the exchange system that can be provided, it cannot provide the above-mentioned standby service in the event of failure of the SCP and IP system. Since there are many limitations outside the switching system, there is an urgent need for providing a more efficient service in a wireline telephone network.

Therefore, the present invention has been created to solve the above-mentioned conventional problems, the announcement broadcast sending module and the music sending module built in the exchange system, so that the call waiting sound service subscriber can be managed for each exchange system, It is an object of the present invention to provide a call waiting service method in a wired communication system, which can maximize the capacity of a call waiting service subscriber and the capacity of a simultaneous call processing service without departing from the existing call processing method.

The present invention for achieving the above object, in performing a call waiting sound service in a wired communication system, a built-in guide equipment module that can provide a variety of music files to the internal exchange system, receiving a call waiting sound service from the subscriber Step and connecting the telephone to a specific number from the subscriber to which the call waiting service is registered, selecting and registering music desired by the subscriber, and when the call is received by the subscriber to which the call waiting service is registered, the exchange proceeds to call processing. And switching to a music file providing module to transmit a music file instead of a ringback tone, and when the subscriber who is registered with the call waiting service answers the call while the music file is being transmitted, release the switch connected to the music file providing module. Subscriber and call waiting service registered It characterized in that made in a step for connecting the subscriber number.

The present invention has a module that can replace the existing IP equipment inside the exchange system, it is possible to manage the call waiting service subscriber for each switching system, and also because the music delivery module is also embedded in the switching system, Do not introduce SCP and IP systems, which are network elements outside the system, separately.

In addition, the call waiting sound is not greatly deviated from the existing call processing method, and by creating a separate process so that the internal resources of the exchange can be used more efficiently, the capacity of the call waiting sound service subscriber and the simultaneous call processing ability can be improved. It is a summary to provide the method to make the maximum possible.

For reference, telecommunications service providers have added computers that control services and databases for service management to existing telephone networks consisting of exchanges and transmission devices, allowing existing telephone networks to be responsible for the simple transfer of information. It provides a new concept of intelligent network service that allows users to quickly and conveniently create and manage new services by hierarchically separating simple telephone call connection and complex service control by providing various services quickly and using database. do.                     

At this time, the SCP (Service Control Point), which is in charge of the entire process of intelligent network service processing, uses a commercial computer or a special type of electronic exchange that can process a large amount of transactions in real time, and uses a single SCP to provide various intelligent network services. You can provide or have different SCPs for each service, and you can get the latest version from SMS if you need the service logic and data in the SCP.

In addition, SSP (Service Switching Point) is a special type of electronic exchange that connects service users and intelligent networks, and recognizes intelligent network service calls among the telephone user's calls and notifies SCP to them, and information necessary for processing intelligent network services from SCP When receiving the call, it connects the call to the desired destination and records the talk time and the called number on a disk or magnetic tape.

Usually, SSP is used by adding communication function with SCP, intelligent network service recognition function, and intelligent network charging function to the existing exchange.

In addition, IP (Intelligent Peripheral) is an intelligent information providing system that connects SSP and voice channel, receives control information of SCP, collects announcement information and collects number information from user and delivers to SCP to execute scenario in SCP. .

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 is an exemplary view showing a call waiting sound service process in a wired communication system according to the present invention. First, in order to realize the present invention, a wired switch operator may provide various music files to an internal exchange system (SSP). Integrate the guidance equipment module (eg IP module) as a module inside the exchange.

Next, when the general subscriber and the enterprise subscriber selects the call waiting sound service, the SSP updates the subscriber supplementary service information to provide the call waiting sound service to the subscriber.

As described above, general subscribers and corporate subscribers (PBX and PRI relay subscribers) registered with the call waiting sound service can select a desired music by calling a specific number and provide a call waiting sound service when the service registration is completed. .

Therefore, when a caller calls a subscriber and an entrepreneur registered with a call waiting service, the call proceeds as in the existing exchange processing, and the music file is provided to the caller instead of providing a ringback tone to the caller as the call proceeds. Switch to the IP module to send music to the caller.

When the called party answers the call, the switch connected to the IP module is released, and the calling party and the called party are connected to make a normal call.

As described above, the call waiting service method in the wired communication system of the present invention includes an announcement broadcast sending module and a music sending module inside the switching system, so that the call waiting service subscriber can be managed for each switching system. It is effective in maximizing the capacity and simultaneous call processing capability of subscribers of a call waiting service while not deviating greatly from the call processing scheme.

In addition, the present invention to minimize the cost required by the SCP and IP system when the service is introduced to the wire operators that want to provide a call waiting sound service, it is possible to minimize the cost of the relay line resources and services consumed when providing services in the switching system and Effective use of internal memory resources improves the performance of the service, thereby providing the service to more subscribers.
