Abstract

PURPOSE: A method for processing an outgoing call by a uniform call distribution in an MSC(Mobile Switching Center) is provided to efficiently use trunk resources and reduce the load of a system by assigning a trunk by the uniform call distribution when processing the outgoing call and assigning the trunk by a subsystem unit. CONSTITUTION: If an outgoing call process is requested(ST1), a trunk composed in a route is classified by a subsystem unit and a database is configured(ST2). The trunk is retrieved while the configured database of the trunk circulates by the subsystem unit(ST3), and a valid trunk is assigned(ST4). The outgoing call is attempted by using the assigned trunk(ST5) and a telephone call is performed(ST6).

Description

Outgoing call processing method by distribution of fixed call of mobile communication exchange

The present invention relates to a mobile communication switch, and more particularly, to a method for allocating a relay line by distribution of a predetermined call during outgoing call processing.

In general, the mobile communication exchange is an application for digital mobile communication and advanced wireless communication, and is a device that provides a mobile communication method to solve the capacity problem for mobile communication demand by transmitting and receiving information through a data communication system.

As shown in FIG. 1, a connection configuration between these general exchanges is connected to each other through an outgoing call processing system serving a call transmitted and received from one exchange to another. It consisted of (10) (20).

As shown in FIG. 2, in the case of the E1 relay line system, one sub-system is composed of 16 links, and one link is composed of 32 relay lines.

The conventional trunk allocation method for outgoing call processing in the mobile communication switch configured as described above includes a sequential hunting algorithm and a circular hunting algorithm.

Here, the sequential search algorithm searches and assigns the state of the relay line configured in the route from the beginning. That is, when handling outgoing calls, search for relay line 0 on link 0, then search for relay line 1 on link 0, search to relay line 31 on link 0, then search for relay line 1 on link 1, and then on relay line A method of allocating a valid relay line by searching 1 and sequentially searching up to the relay line 31 of the link 1.

In addition, the circular search algorithm sets a pointer to the valid relay line previously searched when the outbound call is processed, and when the outbound call processing request occurs, the active relay line searches for the valid relay line from the designated pointer. For example, if relay line 1 of link 0 is assigned during the previous outgoing call processing, a pointer is set to this relay line. Therefore, when outgoing call processing request occurs, the search starts by sequentially searching for the valid relay line from the relay line 1 of the link 0 where the pointer is set.

However, since the sequential method is used to search and allocate the relay line to be allocated, there is a problem that the load of the system is increased because the actual used link is not distributed and is concentrated on a specific subsystem.

Therefore, the present invention has been proposed to solve all the problems in the conventional outgoing call processing as described above, and an object of the present invention is to allocate a relay line by sub-division by subdividing a call during the outgoing call processing. The present invention provides an outgoing call processing method by the distribution of a fixed call of a mobile communication switch that can efficiently utilize the trunk line resources and reduce the load on the system.

In order to achieve the above object, outgoing call processing method by the distribution of a certain number of mobile communication switch according to the present invention,

If there is an outgoing call processing request for serving a call transmitted and received from one exchange to another exchange, forming a database by dividing the relay line configured in the route into subsystem units; Allocating a valid relay line by searching the relay line while circulating the database of the formed relay line in a subsystem unit; The outgoing call is attempted using the assigned relay line to set a call path and make a call.

Hereinafter, an embodiment according to the technical idea of the outgoing call processing method by the constant call distribution of the mobile communication switch of the present invention configured as described above will be described in detail.

Figure 3 is a flow chart showing a call outgoing call processing method by the constant call distribution of the mobile communication switch according to the present invention.

As shown therein, when there is an outgoing call processing request for servicing a call transmitted and received from one exchange to another exchange, a step (ST1) (ST2) of dividing the relay line configured in the route into subsystem units is provided; Allocating a valid relay line by searching the relay line while circulating the database of the formed relay line in a subsystem unit (ST3); Step (ST5) (ST6) is configured to make a call route by attempting an outgoing call using the assigned relay line.

Referring to the accompanying drawings, the outgoing call processing method by the constant call distribution of the mobile communication switch according to the present invention configured as described above will be described in detail as follows.

First, when there is an outgoing call processing request for servicing a call transmitted and received from one exchange to another exchange, a relay line configured in a route is divided into subsystem units to form a database (ST1) (ST2).

Then, the relay system is searched for the relay line while allocating a valid relay line while circulating the database of the formed relay line by the subsystem unit. That is, the search for the relay line 0 of the link 0, the relay line 0 of the link 1 to search the relay line 0 of all links to find a valid relay line. Therefore, if there is no valid relay line, a search for relay line 1 of link 0, a relay line 1 of link 1, and a relay line 1 of all links is searched to find a valid relay line. If a valid relay line is found by this search, a valid relay line is allocated (ST3) (ST4).

The division of relay lines by subsystem and link unit is for distributing calls using relay lines. In other words, by distributing the calls, it is possible to prevent the call from being concentrated in a specific subsystem and to maintain the allocation ratio of the relay lines configured in the route evenly.

Accordingly, by making an outgoing call using the assigned relay line, a call can be made (ST5) (ST6).

As described above, the outgoing call processing method by the constant call distribution of the mobile communication switch according to the present invention, by distributing the call by assigning the relay line by the constant call distribution during the outgoing call processing, When the call processing load of the system increases, the service can be efficiently provided.
