Abstract

PURPOSE: A method for limiting a transit call according to the number of idle trunks in an MSC(Mobile Switching Center) is provided to limit the call according to a limit rate inputted by an operator. CONSTITUTION: If a call request is generated in a route control unit(ST1), it is judged whether the call is a call in a local station MSC or a call to another station MSC(ST2). If the call is the call to the station MSC, a transit call process is performed(ST5). If a transit call request is received, it is confirmed whether a transmit call limit function according to the number of idle trunks is performed(ST7). If the transmit call limit function according to the number of idle trunks is performed, The number of idle trunks is compared with a trunk threshold value inputted by an operator(ST9). If the number of idle trunks is larger than an upper threshold value, an upper threshold value call is limited(ST8). If the number of idle trunks is lower than a lower threshold value, a lower threshold value call is limited(ST4).

Description

Method of limiting relay call according to the number of idle relay lines in mobile switching center

In the present invention, in the relay call processing function from the mobile switching center to the other station switching, the relay according to the number of idle relay lines of the mobile switching center which can limit the call restriction according to the limiting ratio input by the operator according to the number of idle relay lines. It is intended to provide a call restriction method.

In general, the mobile communication exchange is applied to digital mobile communication and advanced wireless communication, and is a device that solves the capacity problem for mobile communication demand and provides an economical, efficient and portable mobile communication method.

In such a mobile switching center, the relay line setting of the conventional switching period is performed as shown in Fig. 1, by performing a call diagram to the other switching center 2 via a route so that one call occupies the relay line. Wow; It is composed of a foreign station exchanger (2) which receives and processes the Hoshi diagram performed by the local exchange (1) via a route.

The operation of the relay line setting in the conventional switching period configured as described above is performed through the relay line, which is a communication channel between the local station switch 1 and the other station switch 2. That is, when two to 1024 relay lines form one route to form a relay line group, the call processing is carried out by occupying one relay line when one call is shown from the home exchanger 1 to the foreign exchanger 2.

However, the conventional exchanger has a problem that an emergency situation such as system congestion may appear when a large number of calls occur when the call is not restricted according to an idle relay line in the relay call function for call processing to another station.

In addition, there is a disadvantage in that the operator cannot register an arbitrary value in the method of registering the rate limit when performing the call limit function.

Accordingly, the present invention has been proposed to solve various problems that occur when performing a relay call processing function in a general mobile communication switch as described above, and an object of the present invention is to provide a relay call processing function from a mobile communication switch to another station switch. The purpose of the present invention is to provide a method of limiting relay calls depending on the number of idle relay lines in a mobile communication switch, so that the call limit can be restricted according to an operator entered limit.

Method for achieving the object of the present invention,

If there is a call limit registration request for the trunk line group, determining a rate limit suitable for the call situation so as to complete the call limit entry into force and perform the call limit as much as the limit rate; If there is a call limit deletion request for a group of relay lines, the limit rate is deleted to perform normal relay call processing.

Hereinafter, described in detail with reference to the accompanying drawings of the present invention.

2 is a block diagram of a relay call processing in an exchanger to which the present invention is applied.

As shown, the relay call related data processing unit 11 for processing data related to the relay call; A relay line call restriction data processing unit 12 for processing relay line related call restriction data so that the relay call related data processed by the relay call related data processing unit 11 can be mounted in the relay line group; Relay call related data processed by the relay call related data processing unit 11 and relay line call 8 processed by the relay line call restriction data processing unit 12.

A relay call performing unit 13 that receives the restriction data and performs a higher relay call processing function; The route controlling the route to perform the relay call processing in the relay call execution unit 12, and determines and deletes the limit rate according to the call restriction registration and deletion request for the relay line group of the relay line call restriction data processing unit 13; It consists of a control unit 14.

3 is a flowchart of processing between the trunk line call limit data processing unit and the route control unit according to the present invention.

As shown, if there is a call restriction registration request for a group of relay lines, determining a limit suitable for the call situation to complete the call restriction entry into effect and allowing the call restriction to be performed as much as the limit rate; If there is a deletion request, it consists of the step of deleting the limit and performing normal relay call processing.

In the call processing step at the time of the call restriction function for the relay line group, as shown in FIG. 4, if there is a call processing request, the call processing step determines whether the call is in the local exchange 1 or the other local exchange 2. One step (ST1-ST3); A second step (ST4-ST6) of determining whether a relay call restriction function has been effected by performing relay call processing when a relay call request is made to said foreign exchange switch (2); When the relay call limiting function is in effect, it consists of a third step (ST7-ST1) for limiting the upper and lower threshold calls by comparing the number of idle relay lines input by the operator whenever a relay line request is made.

Referring to the accompanying drawings, the operation of the relay call limiting method according to the number of idle relay lines of the mobile communication switch according to the present invention configured as described above is as follows.

First, when the call limit for the relay line group is entered into the route control unit 14 by performing restriction registration for the relay line group in the relay line call limiting data processing unit 12, the route control unit 14 determines the rate limit corresponding to the call situation and calls. The relay line call data processing unit 12 is notified that the restricted fermentation is completed.

When a call request occurs in the route control unit 14 (ST1), it is determined whether the call is in the local station switch 1 or the other station switch 2 (ST2). The function performs (ST3), and if the call request to the other station 1 is performed, the relay call processing is performed (ST4).

In addition, if a relay call is requested, it is checked whether the relay call limiting function according to the number of idle relay lines is in effect (ST5). If the relay call limiting function is not in effect, basic relay call processing is performed (ST6), and the relay call limiting function is performed. If this is in effect, each time the relay line is required, the operator-entered median threshold is compared with the number of idle relay lines (ST7). If the number of idle relay lines is greater than the upper threshold, the upper threshold call is limited; if the number of idle relay lines is lower than the lower threshold, the lower threshold call is restricted. Call restriction is performed (ST8-ST11), where the element value of the limit table that matches the characteristics of the call can be used by the operator by changing it to an arbitrary value, and the operator can enter a certain range of specific integers within the range of the limit that can be entered. Should be registered in value units.

On the other hand, if the call limiting non-fermentation / deletion of the relay line group is performed by the relay line call limiting data processing unit 12 to deactivate the call restriction for the relay line group to the route control unit 14, the route control unit 14 deletes the restriction rate. And notifies the relay line call restriction data processing unit 12 that the call restriction non-fermentation is completed, and performs normal relay call processing.

In this way, in the relay call processing function, the operator has a limit to the relay call processing according to the changeable limit data and the number of idle relay lines, so that two threshold values are used to perform many relay call processing functions using a constant relay line. If the number of idle relay lines is less than a certain amount, the operator can limit the call according to the changeable limit rate to prevent system congestion and improve the call handling capability.

As described in detail above, the present invention constrains the system by limiting calls based on the upper and lower threshold values entered by the operator according to the number of idle relay lines in the relay call processing function from the mobile communication switch to the other station. It has the effect of preventing and improving the handling capability of the call.

It also has the effect of changing the rate-related data to any value allowed by the operator in the exchange, allowing the operator to operate the call arbitrarily.
