[Industrial application field]

The present invention relates to a call control method for controlling call state transitions of terminals connected to a communication system. As communication systems have become more sophisticated in recent years, there has been a demand for the provision of more advanced services. The provision of WU simple procedure services (such as call forwarding) can be added to the software of traditional communication systems. However, we considered a service that involves complicated procedures (a service that identifies the caller, searches for detailed information about the caller and the destination of the call, and displays the retrieved caller information on the destination's data terminal). In such cases, if services are controlled only by the conventional communication system, this will lead to a decrease in the processing efficiency of connection control in the communication system. For this reason, it is conceivable to provide services through cooperation between the 1jIi communications system and the information processing system. At this time, in order to enable services using the communication system, the information processing system sends call control messages to monitor various call states between the communication terminals that are subject to service control (the state of the communication bus between the communication terminals). Control 1Tll
(For example, it is required to transition a connected call state to an idle state by a disconnection request.)

[Conventional technology]

Services of conventional communication systems have been provided through cooperation between exchange processing programs and application programs within the communication systems.

However, as services become more sophisticated, application programs become more complex and require more execution time, which reduces the processing efficiency of exchange processing. Furthermore, the required communication services differ depending on the user who purchases the communication system (for each business such as a hotel, business office, department store, etc.), and the development thereof has been carried out by a small number of experts.

[Problem to be solved by the invention]

Therefore, when developing application programs for communication systems, it is necessary to consider the impact on exchange processing. ! This has caused problems such as the difficulty of providing im-personal services and services that search large amounts of data. For this reason, the information processing system iJ! It is desired to be able to control call state transitions between terminals by notifying the l(t system).

The present invention provides a call number management table in an interface placed between a communication system and an information processing system,
Controls the transition of the call state for the call number set in this system, shares functions between the two parties, realizes the provision of advanced services without degrading the performance of exchange processing, and maintains the reliability of the communication system. The purpose is to

The TC8I message generation unit 42 generates and transmits various seso messages to the service control units 5-1 to 5-n. Additionally, TE01 is an abbreviation for Telecommunications Computer Service Interface.

The information processing system 5 includes service control units 5-1 to 5.
-n, etc., and performs various services.

The storage device 6 is for storing messages.

FIG. 2 shows an example of a call number management table according to the present invention.

In FIG. 2, the call number management table 4-1 is a table in which the number of the program ((2) corresponding program number) that performs the switching process of the destination of the call is set in association with (1) the call number.

Next, the operation of the configuration shown in FIG. 1 will be explained in detail using FIG. 3.

In FIG. 3, ``■'' notifies notification condition settings. This is, for example, the terminal's phone number 2-111Lit! "Incoming call notification" is notified to the interface 4 as a notification condition.

■ is set in the table. This way, in the terminal status notification condition table (not shown), the notification destination AP and the terminal status notification condition (here, notification when a call is received) are set in association with the terminal notified in (telephone number 2-1111). Set.

■Sets notification conditions. This sets the interface 4 to notify the PBX of the communication system 2 that "when a call is received from the terminal (telephone number 2-1111)" notified in (2).

(2) An incoming call is detected from the terminal (2-1111).

(2) compares and determines whether it is one loss or not. Here, YE
Since it is S, perform ■.

■Search the notification destination. This is done by searching the terminal status notification condition table (not shown) set in ■, and searching for the corresponding condition (
A search is made to see if there is a notification destination for which notification (incoming call notification) is set.

(2) determines whether there is a notification destination. If YES, execute ■. In the case of NO, the final step (3) registers the call number in the table related to this embodiment. For example, as shown in Figure 2, call number management title 2, this is notified by ■, or a statement and program number are set in association with the number.

[Phase] notifies (call number). Then, the call number set in the nF number management table 4-1 in step (3) is notified to the AP (application program) that is the notification destination. Thereafter, this AP can perform call control (disconnection, change of call destination, etc.) using the notified call number.

In (2), the AP requests a call control request (call number, new destination).

In (2), in response to the call control request (2), the interface 4 refers to the table (call number management table 4-1) and searches whether or not the call number added to the call control request exists.

(2) It is determined whether the call number is set or not. If YES, perform ■. If No, the call number has not been set, so an error is sent in [Phase] (a message indicating that the use of the call number is invalid is sent).

[Phase] notifies a call control request. Then, the interface 4 notifies the PBX of the call number "1ooo", the corresponding program number "l", and the new destination "telephone number 2-3333", as shown in FIG. 2, for example.

(2) The call arrives at the new destination terminal l notified in (2).

Through the above processing, the AP in the information processing system 5 issues a call control request specifying the notified call number for the call once established, and performs call control such as switching to a new destination as necessary. It becomes possible to do so. Also, AP
is not set in the call number management table 4) in response to a call control request that specifies a call number, it is considered an error,
By invalidating the call control request, it is possible to maintain the reliability of the communication system. Furthermore, the AP can easily provide a variety of services based on call control requests without reducing line connection efficiency.

Further, the operation of the configuration shown in FIG. 1 will be explained in detail using FIG. 4.

Determine whether or not the call control request (three-party connection) in (3) has a call number added. In the case of YES, perform the following steps. N
In the case of o, it is determined that the call control request is not a call control request in which a call number has been added, and it turns out to be a new call control request, so the call control request is notified to P 13 X in step (■).

[Phase] makes a three-way connection call and starts a conversation.

@ is determined to be a call number use request in ◎, so the call number in the table is searched.This means that for the call number notified from the AP in ■, for example, call number management table 4 in Figure 2. -1 is searched to see if the call number exists.

[Phase] determines whether a call number has been set. In the case of YES, an additional call control request is requested in (■).

[Phase] makes a call and makes a conversation.

In case (2), error communication is performed because the [phase] is determined as No.
