Number portability device and method of mobile communication network and wired network {A METHOD AND A APPARATUS OF ENHANCED NUMBER PORTABILITY PROCESSING FOR PLMN AND PSTN}

The present invention relates to number portability between a mobile communication network and a wired network, and in particular, establishes a corresponding number portability database in each mobile communication network and forwards it to a number porting communication network of a call connection request. The present invention relates to a number portability device and a method of a mobile communication network and a wired network for simplifying the configuration of an entire system and improving a call connection speed.

The mobile communication system monitors and controls the mobile switching center (MSC) while the registered mobile terminal (MS) moves freely in the service area formed by the base station (RAN). Through the communication path set by the switching and switching (WITCHING), the wireless communication with the desired party anytime and anywhere, and the multiple base stations are continuously arranged at regular intervals to expand the service area to form a nationwide service area, called a mobile communication network do.

The mobile terminal is a high-tech wireless communication device that communicates by moving anytime, anywhere mobile communication service area formed in the country while the individual always carry directly, the mobile communication network forms a unique mobile communication network for each mobile communication service provider and Each operates in a different protocol.

In the wired communication system, a wired communication service provider directly connects a wired line between an exchange and a registered terminal, and establishes a wired communication path by analyzing a call connection request generated between the wired terminals at the exchange. Although it does not have a good communication quality, the communication cost is relatively inexpensive, and it is called a network because it is connected to a large number of exchangers accommodating a certain area and forms the whole country as a service area. Form one wired network and operate with different protocols.

Subscribers subscribed to the respective wired and mobile communication networks are assigned a unique number, and since the unique number includes a number for distinguishing each service provider, for example, after registering to register with a specific communication service provider and changing to another service provider If you register to subscribe, all the unique numbers used previously should be changed.

Therefore, the number portability service solves a part of the problem that the unique number is changed every time the service provider is changed, and the number portability service uses the existing unique number as it is, and registers with another communication service provider and registers for communication service. Will receive.

In order to provide the number portability service, a database for searching for a number portability routine (ROUTINE) must be managed, and the database is expensive because a separate service provider must separately manage the information of each database. There is a problem such as difficult to maintain because it must match at the same time.

Accordingly, in order to provide the number portability service, it is necessary to develop a simple, low cost, and fast process.

Hereinafter, a number portability method of a mobile communication network and a wired network according to the prior art will be described with reference to the accompanying drawings.

Attached to explain the prior art, Figure 1 is a functional block diagram of the number portability device of a mobile communication network and a wired network according to the prior art, Figure 2 is a flow chart of the number portability method of a mobile communication network and a wired network according to the prior art.

Referring to FIG. 1, a number portability device of a mobile communication network and a wired network according to the prior art will be described. The number portability video base (NPDB) 10 inputs the number portability routing information of all wired and mobile communication networks. It records and manages and outputs routing information of number portability searched by search request.

The number portability DB 10 is, for example, a mobile terminal (MS) registered to subscribe to a mobile communication network and assigned a specific unique identification number (ID). In the case of using, the unique identification number becomes a number portability number, and records and stores connection path information, that is, routing information of switching that the number portability number is subscribed to the B mobile communication network.

SIGNAL TRANSFER POINT (STP) 20 is a switch between multiple network switching stations. It connects a wired network, a mobile communication network, and a number portability DB 10 by switching, and establishes a transmission path of the corresponding data. to provide.

The wired network 30 is connected to the registered wired terminal 40 by wire and provides a communication service, and the mobile communication networks 50 and 70 are wirelessly registered with the registered mobile terminals 60 and 80. To provide communication services.

For example, the mobile terminal 80 is initially subscribed to the A mobile communication network 50, but was previously used using the B mobile communication network using a unique number (ID) including an identification code for distinguishing the A mobile communication network. If the previous subscription registration at 70, the unique number calling the mobile terminal 80 becomes a number portability unique number.

When the mobile terminal 80 is to be called from the wired terminal 40, the ID is dialed and applied to the wired network 30, and the wired network 20 analyzes the inputted unique number. Check whether or not number portability.

If the identification is not the unique number of the portability, it connects to the A mobile communication network 50 through the relay switching center 20, and establishes a communication path by connecting to the mobile terminal 60 by the switching.

However, if the inputted unique number is determined to be a number portability unique number by confirmation of the wired network 30, the access port number is connected to the number portability DB 10 through the relay switch 20 and the routing of the number portability unique number is performed. Search and verify the information.

The identified routing information is applied to the wired network 30 through the relay switch 20, and the wired network 30 switches so that the corresponding communication path is set by the routing information confirmed by the search, so that the relay switch ( 20 is connected to the B mobile communication network 70, and the communication path is established by making a call connection with the mobile terminal 80 by the corresponding switching of the B mobile communication network 70.

As in the above example, each wired network and the mobile communication network analyzes the incoming call signal, if the number portability unique number, search the number portability DB 10 to check the corresponding routing information, and analyzes the identified routing information Since the switching process again, the process is complicated and time is required for call connection, and there is a problem that a large number portability DB 10 must be separately constructed and maintained, but it provides a number portability service.

Hereinafter, a number portability method of a mobile communication network and a wired network according to the prior art will be described with reference to FIG. 2.

For example, when the wired terminal 40 requests a call connection by dialing a unique number to the wired network 30 so as to communicate with the mobile terminal 80 (S10), the wired network 30 is a number portability call. It is determined whether the ID (ID) to be processed (CALL PROCESS) (S20).

If it is determined that the number portability call process is to be performed in step S20, the wired network 30 is connected to the number portability DB 10 by the corresponding switching process (S30), and the connected number portability video 10 Search and receive routing information of the route moved to number portability (S40).

Since the wired network 30 that has received the routing information confirmed by the search of the step S40 is switched to using the routing information (S50), the wired network 30 is registered with the B mobile communication network 70 to register a mobile communication service. By the call processing for setting the communication path between the mobile terminal 80 and the wired terminal 40 in use, the wired terminal 40 communicates with the mobile terminal 80 by the unique number portability (S60).

In addition, the wired network 30 analyzes the dialing signal input from the wired terminal 40 and determines that the wired network 40 is not a unique number requiring number portability (S20). Since the switching process for setting the communication path with the mobile terminal 60 registered to the subscription (S70), communication is performed by the communication path connection call processing between the wired terminal 40 and the mobile terminal 60 (S60).

The prior art of such a configuration is disclosed and described in more detail in Korean Patent Publication No. 2002-0034413 (2002. 5. 9).

However, in the above configuration, when a terminal joined to each communication network calls a terminal subscribed to another communication network by number portability, a complicated process and procedure are required, and an operation program for processing number portability is required separately. There was a problem that costly for constructing number portability DB.

In addition, there is a difficult and complicated problem of maintaining and managing the portability information of the portability accurately and promptly due to different independence of each communication service provider and maintaining customer information security.

The present invention maintains the number portability DB itself in each communication network, and if the number portability call connection request is switched, the communication path is set to the communication network transferred by the number portability routing information, thereby simplifying the structure of the entire communication network. The purpose of the present invention is to provide a number portability device and method for a mobile communication network and a wired network, which reduces signal processing and time.

In order to achieve the above object, the present invention provides a wired network for establishing a communication path by connecting to a subscriber by wire and switching a call connection request and managing a number portability DB; A first mobile communication network connected to the wired network, wirelessly connecting subscribers, switching a call connection request, establishing a communication path, and managing a number portability DB; And a second mobile communication network connected to the wired network and the first mobile communication network, wirelessly connecting subscribers, switching a call connection request, establishing a communication path, and managing its own number portability DB.

The present invention has been made in order to achieve the above object, the connection process of switching to the communication network by the network identification number when the call connection request from the subscriber by the respective network; The communication network switched in the process and receiving a call connection request is a step of determining whether the inputted unique number is a unique number that requires number portability; When the number portability is requested in the determination process, a routing step of searching for its own number portability DB and switching to the identified routing information; Since the call connection request of the above process is analyzed and the call is processed, the method comprises a method of establishing a corresponding communication path and completing a process of communicating between the sender and the receiver.
