Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention.

First, referring to FIG. 1, FIG. 1 creates a source code that can simultaneously accommodate the GSM method and the IS-41 according to the present invention, and simultaneously performs the GSM and the IS-41 without modifying a large amount of source code. Provide an acceptable personal mobile communication switch.

Each of the first, ..., N-th base stations 10-1, ..., 10-n wirelessly connects to a personal mobile subscriber in the corresponding area, and requests the terminal for authentication.

A plurality of base station controllers 10, ..., connect with a plurality of base stations 10-1, ..., 10-n, and one base station controller has one or more base stations 10-1, ..., 10 -n) and wirelessly receive and transmit a signal from each base station 10-1, ..., 10-n to control the processing of this signal.

The personal mobile communication exchange 20 is connected to a plurality of base station controllers 10, ..., and is connected to a plurality of base station controllers 10, ..., 10-n. In the case of calls from other exchanges and own stations by wirelessly connecting signals from.), It connects its own internal calls, connects the calls through switching operation, and performs the process of charging.

The exchange includes an access switching subsystem (ASS) 160, an Interconnection Network Sub-system (INS) 190, and a Central Control Subsystem (CCS) (not shown in the figure). And exchange information with each other.

The central control subsystem provides system-wide maintenance, test and measurement, billing, and statistical functions, as well as mess storage control management, operators such as cartridge tape (CT), magnetic tape (MT), hard disk, and more. Various control and output door control function and data channel connection function with other system are performed.

The network control subsystem 190 is located at the center of the system and serves to connect the match exchange subsystem 160 with each other or between the match exchange subsystem 160 and the central control subsystem (not shown). do.

In addition, the network control subsystem 190 performs a centralized function such as number translation, route control function, and space switch connection among call processing functions, and is also responsible for a function of generating and distributing a system clock with a network synchronizer.

The matching exchange subsystem 160 includes subscriber and relay line matching, time switches, various signaling devices, and the like to perform most call processing functions and self-operating maintenance functions.

The matching exchange subsystem 160 may accommodate a remote access switching module (RASM) or a remote system (hereinafter referred to as RS) which is a remote system through an interface circuit.

The visitor location register (VLR) 170 is located in the network control subsystem 190 of the personal mobile communication exchange and serves as a small database for receiving and temporarily storing information of a plurality of subscribers.

The home location register 30 also serves as a large database containing subscriber information such as code numbers of the subscribers and other service information, for example, additional service information.

The base station controller matching block 110 converts a signal coming from the base station controller 10, ... into a signal usable by the personal mobile communication switch 20.

Although the standard specified by the base station controller and the GSM, the signal between the base station controller matching block uses the same standard as that in which the signal between the home location register matching block and the home location register is received and transmitted, but the CCITT recommendation S series. In the following, IS-41 is used between the home location register and the home location register matching block, and the protocol of IS-651 or IS-631 is used between the base station controller and the base station controller matching block.

The outgoing mobile call control block 120 is also connected to the number translation block 180, the visitor subscriber management block 170, and the home location register matching block 150 to transmit the calling and called numbers to the number translation block 180. Number translation is also required, and the location information of the called subscriber is requested to the home location register 30 or the visited subscriber management block 170.

Incoming mobile call control block 130 transmits a paging request for searching for a called subscriber to the corresponding base station controller 10 as a block for processing related to the called subscriber, and the base station controller 10 transmits a plurality of base stations 10-1,. .., 10-n) transmits a signal back to the destination terminal, the destination terminal is again the base station (10-1, ..., 10-n), the base station controller 10, the base station controller matching block 110 And a paging response is delivered to the terminating mobile call control block 130.

In the number translation block 180, the number translation is performed, and the number translation block 180 transmits the number translation to the incoming mobile call control block or the outgoing mobile call control block 120.

The home location register matching block 150 is responsible for registration between the home location register 30 and the personal digital communication switch 20, and communicates with the home location register 30 with the signal of NO.7 and the NO.7 signal. It receives and transmits, matches with the internal signal commonly used in the personal communication switch 20, and conversely serves to switch the internal signal of the personal communication switch 20 to NO.7.

The home location register 30 is a large database having subscriber location information and other various additional service information, and communicates with each other using the home location register matching block and the NO.7 protocol.

In case information flows between the home location register and the home location register matching block, GSM uses a single NO.7 regulation prescribed by GSM, and Korea uses the S series, a recommendation from CCITT, to provide information. Receive.

Referring to FIG. 2, first, an operation code is received in an area having each NO.7 area, that is, for example, a home location register 30, a home location register matching block 150, and the like (step) 200).

In the extended area of the received code (most significant bit in the present invention), it is determined whether the bit is designated as the first logic level (step 210).

In the example of this drawing, the extended area is given as one bit in the example of FIG. 210, but a plurality of bits can be set when the extended area is to be extended. Shall be used.

As a result of the determination in step 210, if the extended zero bit is the first logical level, the operation codes 302-314 in the lower bits are retrieved from the operation code information of the IS-41 (step 220).

In operation 220, the analyzed resolution is performed (step 230).

If it is determined in step 210 that the bit of the extended area is not the first logical level, that is, if the most significant bit is 1, the operation code 322-334 in the lower bit is retrieved from the data of GSM (step 240). ).

Search and execute the corresponding operation code analyzed (step 250).

Referring to FIGS. 3A to 3B, only a few significant bits (LSB) bits are used in an area allocated to one byte and the remaining bits are emptied into an extended area. Can accommodate all -41 protocols

Thus, as shown in FIGS. 3A and 3B, GSM and IS-41 classifiable codes are inserted into the most significant bit (MSB) of the extended region to enable processing.

For example, it is possible to use a mixture of codes even between four protocols having different codes using the upper two bits. In this case, the code values of 0, 1, 10, and 11 are given to the upper bits of each code to find the protocol value corresponding to the given code, and then it is recognized and processed as the code system of the corresponding protocol system.

However, the remaining bits except the extended region use the lower 7 bits or 6 bits as the code value defined according to each recommendation. In the case of using 7 bits, it can have 128 operation code values, and in case of accommodating 6 bits, it has 64 operation code values.

In this case, if more than 64 operation code values of one of the prescribed protocols that accommodate a plurality of protocols are mixed, the four protocols cannot be accommodated as two higher bits. That is, it must be flexible depending on the number of operation code values.

Each of these operation codes is contained in the base station controller matching block 110, the base station controller 10, the home location register matching block 150, and the home location register 30, so that the required operation code information is stored in the memory of each block. The operation information stored in the area can be fetched and executed.

The above-mentioned method encompasses GSM from the standpoint of IS-41, and conversely, the IS-41 can be accommodated from the standpoint of GSM.

This is done by setting the classification number inserted in the extension bit as 0 for GSM and 1 for IS-41.

All of the above methods are compatible between GSM and IS-41, and the principle is the same.

In addition, since the operation code values of GSM and IS-41 each have 100 or less operation codes, at least one upper extension bit remains.

As described above, the present invention provides a method for accommodating both the GSM scheme and the IS-41 scheme in one personal mobile communication switch using bits of the extended area of the operating area, thereby providing source code included in the exchange. It is effective to operate efficiently.

The IS-41 and GSM are simultaneously connected by giving code numbers to the extended area to integrate the GSM and IS-41 methods that can simultaneously accommodate the operation of the GSM and the IS-41 in a block particle that integrates the protocol processing. Acceptable

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.
