DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange connection system and a telephone exchange connection method for a subscriber telephone such as a fixed telephone or a portable telephone, and more particularly, to a method for making a call from a calling subscriber telephone (called subscriber). A telephone exchange connection system which enables a service of providing information such as voice, music, etc., utilizing the time during which the telephone number of the telephone is dialed and connection is made by the exchange server to the called subscriber telephone; and It relates to a telephone exchange connection method.

[0002]

2. Description of the Related Art A conventional telephone exchange connection has a connection between a calling subscriber's telephone and a called subscriber's telephone as a first definition. (Called off-hook), dials the telephone number of the called subscriber's telephone (called outgoing call), and the exchange server analyzes the dial signal and connects to the called subscriber's telephone. is there.

During this time, a dial tone called a dial tone is transmitted from the switching server to the calling subscriber telephone during a period in which the dial signal is transmitted from the calling subscriber telephone, and then the dial signal is analyzed. A ring back tone is transmitted until the connection to the called subscriber telephone is completed. If the called subscriber is busy, a busy tone is sent out; if not, a ringing tone is sent out; if the called subscriber's handset goes off-hook, the connection is completed and the call is terminated. It becomes possible and charging starts.

Thus, the calling subscriber confirms that a dial signal has been transmitted by receiving the dial tone, and confirms that it is being connected to the called subscriber telephone by receiving the ring back tone. In addition, the reception of the busy tone indicates that the called subscriber's telephone is busy, and the reception of the ringing tone indicates that the called subscriber's telephone is being called.

[0005] However, with the recent spread of mobile phones, the values of telephone subscribers have been diversified, and various services have been required. For example, various services have been realized, such as so-called ringtones that convert the ringtone of a subscriber telephone into a favorite music, a mail reception / transmission service using a telephone, a digital information transmission / reception service, and a payment settlement service when purchasing an article.

In such a background, the period from when the caller makes a call to when the caller is connected to the callee is merely a waiting time for the subscriber, and depending on the subscriber, a ringback tone is required. I want to make better use of that time, rather than receiving the music I receive during that time, or
It is assumed that the user wants to receive favorite information by voice or the like. For example, subscribers have a wide variety of tastes, such as traffic information and information about introducing movies and concerts. It is also conceivable that there is a demand for companies and local governments to provide their public information, event information, etc. to an unspecified number of telephone subscribers. In this case, the telecommunications carrier that provides the telephone network can provide the information providing service to the company or the local government that provides the information for a fee.

Conventionally, in the above-mentioned switching connection, a technique for delaying the time until transmission of a ring-back tone or the time for starting transmission of a ring-back tone and performing the above-described information providing service during this time has been proposed. For example, it is disclosed in JP-A-5-48728.

[0008]

However, the above technique delays the time until the transmission of the ringback tone or the transmission start time of the ringback tone, and calls out the information prepared in advance during this time. This is transmitted to the local subscriber telephone, and for the caller, there is a problem that the time required to receive the ring back tone and wait for the connection is wasted. In addition, if the transmission start time of the ringback tone is intentionally delayed until the predetermined information providing service is completed, the processing of the switching connection is temporarily suspended, resulting in a waiting time until the call. There was a problem that it increased.

Accordingly, the present invention relates to a time period between a call originating from a calling subscriber telephone (the telephone number of the called subscriber telephone is dialed) and the connection being made by the switching server to the called subscriber telephone. It is an object of the present invention to provide a telephone exchange connection system and a telephone exchange connection method capable of providing information such as voice and music without interrupting the exchange connection process, instead of transmitting ringback tone. I do.
