Description

Call processing method for special purpose subscriber at exchange.

The present invention relates to call processing for special purpose subscribers in an exchange, and in particular, for establishing a special purpose subscriber for small special purpose subscribers, by checking the presence of special purpose subscribers according to the call occurrence, The present invention relates to a call processing method for a special purpose subscriber at an exchange that is connected to an exchange connected to a general-purpose national network dedicated to functions.

In general, a mobile network operator provides a special function for a mobile subscriber, and the special function may generate various types of requests such as traffic data conversion, specific announcement broadcast transmission, call state monitoring, and additional function provision.

Therefore, in order to provide a special function to a small number of mobile subscribers limited to a special function rather than a general mobile communication service, it is necessary to additionally establish the overall function of a nationwide mobile communication network, but it is a nationwide investment that requires a huge investment for a limited small user. It was impossible to build a special purpose network.

As described above, in order to provide a special function to a conventional mobile subscriber, the special functions may be provided only when the special function performing units 10a-1 to 10d-1 are provided in each of the exchangers 10a to 10d.

Therefore, if the exchange model is different, the special function must be developed separately by the manufacturer according to the exchange model, and even if there are only a few subscribers using the special function, the special function must be added to all exchanges. Even minor cases have significant development and maintenance costs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and the present invention provides a general-purpose national network for a special purpose small-scale mobile subscriber without having to add all special functions to the national network exchange. By providing a special function to the special purpose subscribers through the universal network, it is possible to provide special functions to small special purpose subscribers anywhere in the country, and it is not necessary to add special functions to all exchanges. For the purpose of providing it.

In order to achieve the above object, the present invention, when a call occurs, the process of determining whether the call is a special purpose subscriber; If the call is a special purpose subscriber call, inserting a specific code indicating that the call is a special purpose subscriber call outgoing and sending it to the special function exchange side for transmission; Deleting the specific code included in the incoming call in the special function interrogator, and re-confirming whether the incoming call is a special purpose subscriber call; If the incoming call is a special-purpose subscriber call as a result of the confirmation, the process includes processing a special function and connecting the call to the called subscriber.

Further, whether the call is a special purpose subscriber call is characterized by determining using any one of a subscriber profile stored in a home location register, a specific number group assigned by a mobile operator, and a specific subscriber condition.

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

In the exchange according to the embodiment of the present invention, the call processing network configuration for the subscriber of the special purpose is shown in FIG. 2, when a call is generated, the call is determined to be a specific purpose subscriber, and then the call is dedicated to the exchange function dedicated to the special function. When a plurality of exchanges 20a to 20c transmitting a call and a call requesting a special function are transmitted from the plurality of exchanges 20a to 20c, a special function exchange for processing the special function and then processing the call to the called station. 20d is provided.

And, as shown in Figure 3, the plurality of exchanges (20a ~ 20c) is a subscriber call processor 21a for inserting and transmitting a predetermined code in front of the called number when the generated call is a special purpose subscriber, and the corresponding incoming call A number translation unit 22a for translating the number of the predetermined code inserted in the preceding part to connect the destination, a switching control unit 23a for switching the corresponding call, an outgoing call processing unit 24a for transmitting and receiving outgoing calls, It is provided with the operation maintenance processing part 25a which processes the operation maintenance of each circuit part.

And, as shown in Fig. 4, the special function exchange 20d deletes a predetermined code in front of a called number transmitted from a plurality of exchanges 20a to 20c, and then enters an incoming call to determine whether it is a special-purpose subscriber. Special functions include a processor 21d, a number translation unit 22d for translating the called party number to connect the destination, a switching control unit 23d for switching the corresponding call, and a call applied from the switching control unit 23d. A special function execution unit 26d for processing and transmitting, an outgoing call processing unit 24d for outgoing and transmitting the call, and an operation maintenance processing unit 25d are provided.

Referring to the accompanying drawings, the operation of the present invention configured as described above in detail as follows.

First, for example, a process of processing a call of a special purpose subscriber assuming a first exchange as an outgoing exchange and a third exchange as an incoming exchange will be described. When a call occurs at the first exchange 20a as the outgoing exchange ( In step S1), the subscriber call processor 21a checks whether the corresponding call is a special-purpose subscriber, and in order to determine whether the caller is a special-purpose subscriber, a home location register storing a mobile subscriber profile; (Not shown) to add specific fields to the subscriber profile to check whether the subscriber requires special features, to assign a specific number of groups assigned by the mobile operator, or to meet specific subscriber conditions during call processing. In a characteristic way, it is checked whether the corresponding signal is a special-purpose subscriber (step S2).

Accordingly, the destination is confirmed through the number translation unit 22a, and the path is connected through the switching control unit 23a.

Then, outgoing processing unit 24a performs outgoing processing by inserting a specific code (Prefix) in front of the called party number in order to route to special function exchange 20d. For example, if the originating subscriber who generated the called number '019-300-5678' is a special purpose subscriber, insert '600' in front of the called number to make '600-019-300-5678' special. Outgoing processing is performed and sent to the function exchange 20d side (step S3).

At this time, in the insertion of a specific code at the front of the called party, the specific code must be paralleled with data work that can be routed from the all exchanges in the network to the special function exchange 20d, and all the exchanges 10a to 10c in the network The specific code inserted by the originating exchange is translated and routed to the special function exchange 20d (step S4).

Therefore, the call routed to the special exchange is deleted by the incoming call processing unit 21d in the special function exchange 20d at the originating exchange 10a, so that the call is deleted, and the incoming call is a special purpose subscriber. You will be confirmed.

At this time, similarly, the procedure of confirming whether the subscriber is a special purpose subscriber adds a specific field to the subscriber profile stored in the home location register to confirm whether the subscriber requires a special function, or the calling party is assigned by the mobile operator. In a specific number group or in the process of call processing, a specific method that corresponds to a specific subscriber condition is used to determine whether the call is a special purpose subscriber.

Accordingly, the number translation unit 22d checks the destination after translation of the called number, and sets the path from the switching controller 23d to the special function performing unit 26d.

Therefore, the special function performing unit 21d provides the special function to process the outgoing call through the outgoing call processing unit 24d as the destination of the traffic data having been processed. At this time, the operation maintenance processing is performed in parallel in each circuit unit through the operation maintenance processing unit (steps S5, S6, and S7).

As such, the present invention does not additionally establish all the special functions at the national network exchange for the special purpose small-scale mobile communication subscribers, and connects the switch dedicated to the special function to the general-purpose national network through the general purpose network to the special purpose subscriber. By providing special functions, it is possible to provide special functions to small special purpose subscribers anywhere in the country, and the development and maintenance costs are low because no special functions need to be added to all exchanges.

As described above, the present invention provides a general purpose network to a special purpose subscriber by connecting an exchange dedicated to a special function to a general purpose nationwide network without additionally constructing all special functions at a national network exchange for a special purpose small mobile communication subscriber. By providing special functions through the service, it is possible to provide special functions to small special purpose subscribers anywhere in the country, and the development and maintenance costs are low because no special functions need to be added to all exchanges.
