[Prior Art] It is not economical to equip all switching systems with a call processing function for services with low demand, and a common method is to equip some switching systems within a network with this function and process the calls. It is true. However, since the language assistance service is requested after the call is set up, it is impossible to determine whether the service is available at the call set-up stage, and there is a possibility that the service will be used at the call set-up stage. It was necessary to either transfer all calls to a switching system equipped with the function of providing language assistance services, or to make all switching systems equipped with the function of providing language assistance services.

[Problem to be solved by the invention] In recent years, with the diversification of services, the functions of special services with low demand are concentrated in specific communication nodes, and switching systems are dedicated to the function of communicating large amounts of traffic. This layered network structure has become commonplace, and it is not realistic to equip all switching systems with call processing functions for all services.

[0006] Among calls that may use language assistance services, very few calls actually request language assistance services, and all calls that may require language assistance services are handled by the language assistance service provision function. If the data is transferred to an exchange system equipped with the above, the processing capacity of the outgoing and terminating lines of both systems and the destination exchange system will be strained.

For example, in a switching system that does not have a language assistance service provision function, a call that may use a language assistance service has a load of 100 erlangs, and a call that actually requests the language assistance service has a load of 1 erlang. If so, in the conventional method, this 100 erlang load becomes the load on the forwarding exchange system, but the load actually required for the language assistance service is 1 erlang, and the remaining 99 erlangs. This means that the load that could originally be handled only by the transfer source switching system is transferred, and one call is processed by two switching systems, the transfer destination and the transfer source, and as a result, the processing of both switching systems is reduced. This resulted in a decline in capacity and a meaningless increase in the amount of line equipment installed. In this regard, the present invention aims to provide a call processing method that requires a language assistance service that is effective and appropriate for solving the problem.

[Means for Solving the Problems] The above problems are achieved by the present invention adopting the following novel characteristic configuration method. That is, the features of the present invention include an exchange system equipped with a language assistance service provision function, an exchange system not equipped with the function, an outgoing line and an incoming line accommodated in both systems, and an intersystem line connecting both systems. If a call comes in from the incoming line of a switching system that does not have a function to provide language assistance services, and a request for language assistance service is received after establishing a call path with the outgoing line of the same system, A new loop-shaped communication path is set up between the switching system having an assistance service providing function using the inter-system line, and then the outgoing line, the incoming line, and the loop-shaped communication path are combined into one line. This is a method of processing calls requesting language assistance services that allows language assistance services to be provided even in switching systems that do not have a language assistance service provision function by switching connections so that the language assistance service is provided.

[Operation] The system of the present invention uses the method described above to first set up a communication path for a call that enters a switching system that does not have a language assistance service provision function, regardless of whether or not a language assistance service is requested. After that, when there is a request for language assistance services, a loop call is made between the exchange system that does not have the function of providing language assistance services and the exchange system that does have the function of providing language assistance services via the intersystem line. Since the outgoing line, the incoming line, and the loop-shaped communication path are newly connected as one line, it is possible to deal with calls that enter the exchange system without language assistance service provision function. will also be able to provide language assistance services.

In the configuration example of FIG. 1, the stepwise line connection formation procedure of this embodiment will be explained in detail with reference to FIG. First, when the switching system 2 receives a call from the incoming line 2a, the switching system 2 sets up a communication path with the outgoing line 2b [Fig.
See (a)]. Next, upon receiving the language assistance service request signal S1 from the incoming line 2a, the switching system 2 transmits a line setting request signal S2 to the switching system 1 to set up the intersystem loop line c [FIG. 2(b) )
reference]. This request signal S2 is a normal inter-exchange signal, and can be identified as a request for setting the inter-system loop line c.

Subsequently, the switching system 1 receives this line setting request signal S2 and sets up the intersystem loop line c for the switching system 2 [see FIG. 2(c)]. Furthermore, upon completion of the setting of the intersystem loop line c, the switching system 2 switches the communication path between the incoming line 2a and the outgoing line 2b from the incoming line 2a to the intersystem loop line c to the outgoing line 2b. , After the connection change is completed, the language assistance service request signal S1 is transferred to the exchange system 1 [Fig.
see d]. Eventually, exchange system 1 becomes exchange system 2.
The language assistance service request signal S1 is received from the computer and the service is provided. The subsequent processing is the same as that for a call requesting normal language assistance services.

Thus, in the present invention, for example, 20% of all incoming calls to a switching system without language assistance services are calls that may require language assistance services, and 1% of these calls actually require language assistance services. In the case of a call requesting a language assistance service, in the conventional method, all 20% of this traffic was transferred to a switching system equipped with a processing function for the language assistance service, whereas in the present method, 0.2% of the total traffic was transferred to a switching system equipped with a processing function for the language assistance service. This can be done by transferring % of calls.

[0014] In this case, assuming that the number of incoming lines of a switching system not equipped with a language assistance service processing function is 1000 lines, in the conventional system, it was necessary to prepare approximately 221 inter-office lines for the language assistance service. In contrast, the system of the present invention can be handled by simply preparing about 14 lines (7 interoffice lines + 7 incoming lines) (calculated using a call loss rate of 1/100). Similarly, the number of outgoing lines required for the forwarding destination exchange system has been significantly reduced, and the processing capacity of the forwarding destination exchange system was equivalent to 3200 BHCA for language assistance in the conventional method, whereas the present method requires 32BH when applied
This is a sharp decrease to the equivalent of CA (calculated as incoming line usage rate of 80% and average holding time of 3 minutes/call).

As described above, according to the present invention, only when there is an actual request for language assistance service, a line is established between the exchange system 2 which does not have the language assistance service processing function and the exchange system 1 which does have the processing function. In order to provide services with low demand, all switching systems are equipped with a service provision function, which increases costs, and all calls are equipped with a language assistance service provision function. This has excellent effects, such as making it possible to prevent a decrease in the processing capacity of the exchange system and an increase in required line equipment due to transfer to the exchange system. Note that the method of the present invention is also applicable to other special services in which a service request is made after a call is set up.
