Abstract

PURPOSE: A method and a system for using ACQ(All Call Query)/QOR(Query On Release) according to introduction of number mobility are provided to effectively and flexibly operate an SMSC(Short Message Service Center) according to a network situation. CONSTITUTION: When an origination MSC(109) receives a short message transmission request from an origination terminal(103)(S501), it transmits subscriber information on the origination terminal(103) and a destination terminal(121) together with the short message transmission request to an origination SMSC(107)(S503). The origination SMSC(107) extracts an authentication method of each prefix from a prefix authentication method database(S505) and determines whether an authentication method of a prefix of a destination is ACQ(S507). If the authentication method of the prefix of the destination is ACQ, it is checked whether the destination terminal has changed its number(S515). If the authentication method is not the ACQ, a call request is transmitted to a termination MSC(119)(S509). When the origination SMSC(107) receives a call connection/non-connection message from the destination MSC(119)(S511), it determines whether the message is a call release message(S513). If the message is the call release message, it is checked whether the destination terminal(121) has changed its number(S515). The origination SMSC(107) sets a receiver phone number according to the number mobility of the destination terminal(121) and sends a short message to the destination terminal(121)(S517).

Description

Method and system for using ACQ way and QOR way together according to mobile number portability}

The present invention relates to an ACQ / QOR mixed acceptance method according to the introduction of number portability, and more particularly, a QOR (Query On Release) routine is applied to a station number with a small number portability and ACQ (All Call) for a station number with a high number portability. The present invention relates to a method and a system for accommodating ACQ / QOR according to the introduction of number portability applying a query routine.

Existing mobile networks only accept their own network codes, but as the number portability system is implemented, mobile operators are required to accept not only their own network codes but also other company's network codes.

Number portability means that a service subscriber can change a service provider, a service location, and a type of service without changing the telephone number used previously. During number portability, a service provider number portability (Service Provider Number Portability) method is provided so that a subscriber can continue to use a telephone number previously assigned to a subscriber even if the subscriber cancels the subscription to the carrier A and newly subscribes to the carrier B. Provider Number Portability.

Number portability service allows users to freely select a service provider by comparing service quality and rates without changing existing phone numbers, and enables newer operators and new operators to compete fairly. It is being promoted in each country at the national level for the purpose.

In the past, SMSC (Short Message Service Center), which processes messages based solely on mobile directory numbers (MDNs), has had to accept and process messages according to network codes of other companies.

The mobile communication service system recognizes a mobile communication terminal using a mobile station identification number (MIN) or an international mobile subscriber identity (IMSI).

A mobile identity number (MIN) is a 34-bit number that digitally represents a 10-digit telephone number assigned to a mobile station (mobile phone terminal). There are MIN 1 and MIN 2 as designated numbers (aka telephone numbers) of terminals. MIN 1 is a phone number of 7 digits assigned to the terminal and consists of 24 bits. MIN 2 is a 3 digit area number of 10 bits. For example, in 011-YYY-XXXX, MIN 1 is YYY-XXXX and MIN 2 is 011.

The International Mobile Subscriber Identity (IMSI) is a unique 15-digit identification number assigned to a mobile terminal when subscribing to a Global Mobile Communication System (GSM) service. The Mobile Country Code (MCC) and Mobile Network Code (MNC) ), Mobile subscriber identification number (MSIN) and national mobile subscriber identification number.

The mobile subscriber identification number (MSIN) is used at the same value as the mobile identity number (MIN: Mobile Identity Number), and before the introduction of number portability, the mobile station identification number (MIN) was called a subscriber number (MDN: Mobile Directory Number). That is, before the introduction of number portability, the telephone number of the customer and the identifier for identifying the corresponding user terminal in the mobile communication service system were the same. Therefore, the call back number entered when the user of the calling terminal transmits the short message is the same number as the mobile station identification number (MIN) or the telephone number to be actually contacted.

To this end, a number portability service method for confirming whether a terminal has been moved is provided. The number portability service method can be largely divided into an ACQ (All Call Query) method and a QOR (Query On Release) method.

1 is a diagram illustrating a configuration of a number portability providing system using a conventional All Call Query (ACQ) method.

Referring to FIG. 1, a calling terminal (MSC) 103 is connected to a calling network 105 for call connection and short message transmission of the calling terminal 103 through a wireless network. 105 may include an originating exchange 109, an originating short message service center (SMSC) 107, a number portability database 111, and the like.

Although not shown in FIG. 1, the source network may include a base station transceiver (BTS), a base station controller (BSC), a home location register (HLR), for call connection and short message transmission. Visitor Location Register (VLR), Authentication Center (AC) may be further included.

The call connection request and the short message transmission request received from the originating terminal 103 may be exchanged through a base station transceiver subsystem (BTS) (not shown), a base station controller (BSC) (not shown), or the like. The terminal is transmitted to a mobile switching center (MSC) 109.

A Mobile Switching Center (MSC) 109 is an automated system that configures an access point for user traffic between a mobile communication network and another mobile telephone switching center (MSC) in a public telephone network, the same or another mobile communication network. The mobile switching center (MSC) is interlocked with the fixed network to provide circuit switching services to mobile subscribers, and as an additional feature, it can always provide mobile phone services by tracking the location of mobile subscribers. It has a call channel hand-off function that keeps the communication service available even if the location changes.

The calling switching terminal (MSC) Mobile Switching Center (MSC) 109 is connected to the calling terminal 103 from a home location register (HLR) and a visitor location register (VLR) (not shown). The corresponding subscriber information is provided.

In addition, the originating exchange terminal 109 transmits a call connection request and a short message transmission request to the originating short message service center (SMSC) 107.

The subscriber 123 of the terminal 121 subscribes to the service provided by the carrier A (the original carrier) and receives a mobile directory number (MDN) from the carrier A (the original telephone number). After that, the subscription contract with the carrier A (the original carrier) is canceled, and the service provided by the carrier B (the current carrier) is subscribed to, thereby obtaining a new subscriber number (MDN: Mobile Directory Number) from the carrier B (the current carrier) ( Current phone number). However, due to the introduction of number portability, by storing the number porting information of the subscriber station in the number porting database 111 provided in the carrier, it is possible to use the original telephone number that has been used even after the carrier change.

In the All Call Query (ACQ) scheme, in order to provide portability, the originating exchange 109 in the originating network 105 does not route all calls required from the originating terminal 103 of the originating subscriber 101 to the corresponding telephone number. In order to query the number portability database 111 before routing, obtain information such as whether the call has been moved, and if so, where it is moved and connect the call using the information obtained from the number portability database 111.

For example, the terminal 121 is subscribed to the network A 117 of the carrier A, and has been assigned a telephone number (hereinafter referred to as an original telephone number), but later withdraws the subscription to the carrier A, A case of newly joining the network 113 will be described as an example. In this case, the terminal 121 receives a new telephone number b (hereinafter referred to as the current telephone number) to be used in the network 113 from the B communication service provider, and the telephone number of the terminal 121 is stored in the number portability database 111. The information is changed from the original telephone number in the network to the current telephone number in the network.

In the above situation, the user 101 of the originating terminal 103 establishes a call connection with the terminal using the previous original telephone number assigned to the terminal 103 (by dialing). , The originating exchange 109 queries the number portability database 111 if the original telephone number was routed to another telephone number.

If, as a result of the query, information is provided from the number portability database 111 that the original telephone number has been changed to the current telephone number of the network, the originating exchange 109 transfers this information (the call request for the current telephone number b) to the network 113 It provides to the current destination exchange (115) in the) to connect the call between the calling terminal 103 and the called terminal 121.

In the short message transmission process in the ACQ (All Call Query) method according to the introduction of number portability, if the short message transmission is requested by the calling terminal 103, the originating exchange 109 in the outgoing network 105 requests the short message transmission request. Receives and forwards the short message transfer request to the originating Short Message Service Center (SMS) 107.

The originating SMSC (Short Message Service Center) 107 checks the number of the corresponding destination terminal using the number portability database 111.

If the called terminal 121 is not moved, the mobile station identification number (MIN: Mobile Identity Number) of the called terminal 121 is set to the received telephone number of the short message, and the number is determined. As a result, when the called terminal 121 is moved by number, the subscriber's telephone number (MDN: Mobile Directory Number) of the called terminal 121 is set as the received telephone number of the short message.

And a short message is sent to the called terminal 121 using the received telephone number depending on whether the number has moved.

As described above, the ACQ (All Call Query) method has the advantage that the system is conceptually simple and the possibility of a dispute that can occur between operators is low, but the number portability database 111 is queried whether all numbers are moved. Since it has to overload the system, it has a disadvantage of investing a lot in the telephone network to solve this problem.

2 is a diagram illustrating a configuration of a number portability providing system using a conventional query on release (QOR) method.

Referring to FIG. 2, since the system configuration of FIG. 2 is as shown in FIG. 1, a description of the configuration will be omitted.

When a call for a predetermined telephone number is requested from the calling terminal 101 in the mobile communication system, the call is first requested to the originating exchange 119 in the terminating network 117 corresponding to the telephone number. That is, when the calling terminal 103 requests a call for the original telephone number (a), the calling switch 109 in the calling network 105 of the A carrier network 117 jurisdiction over the original telephone number (a) Request a call to the exchange 119.

In this case, it is assumed that the terminating terminal 123 terminates the contract with the carrier A, which is in charge of the network 117, newly joins the carrier B of the network 113, and receives a new current phone number. In this case, since the terminating terminal 123 having the original telephone number a does not exist in the originating exchange 119, the originating exchange 119 is the original telephone number for the call request of the originating exchange 109. (a) provides a call control message to the originating exchange 109 in the originating network 105 indicating that the call cannot be established.

When a call release message is provided from the network A of the carrier A, the calling exchange 109 in the calling network 105 queries the number portability database 111 whether the original telephone number a is routed to another telephone number. . As a result of the query, if the source telephone number (a) is provided from the number portability database 111 that the original telephone number of the B carrier network 113 has been changed from the number portability database 111, the originating exchange 109 network the call connection to the current telephone number. It requests the current destination exchange 115 in the 113 to connect the call between the calling terminal 103 and the called terminal 121.

The QOR (Query On Release) method does not ask the number portability database 111 whether or not the number of the destination terminal 121 is shifted every time a call is requested, but the initial subscription network corresponding to the original telephone number of the destination terminal 121. The destination terminal 121 is entered into the number portability database 111 only when a call is first requested from the originating exchange 119 of 117 to provide a message from the first subscription network 117 that the corresponding terminal 121 does not exist. ) Will ask whether to move the number.

As described above, when the short message is transmitted through the QOR (Query On Release) method, it is determined whether the calling terminal has a number shift.

If the called terminal 121 is not moved, the mobile station identification number (MIN: Mobile Identity Number) of the called terminal 121 is set to the received telephone number of the short message, and the number is determined. As a result, when the called terminal 121 is moved by number, the subscriber's telephone number (MDN: Mobile Directory Number) of the called terminal 121 is set as the received telephone number of the short message.

And a short message is sent to the called terminal 121 using the received telephone number depending on whether the number has moved.

Therefore, the QOR (Query On Release) method has the advantage that the overall system load is less than that of the ACQ (All Call Query) method, but there is a disadvantage that the call connection time of the number-shifted call and the call that is not.

Therefore, it is necessary to operate SMSC efficiently and flexibly in accordance with the network situation in consideration of network complexity, system load, competition in the market, cost and benefit analysis, and number of subscription genres.

Accordingly, an object of the present invention is to mix and match the QOR (Query On Release) and ACQ (All Call Query) method in the Short Message Service Center (SMSC), and it is efficient to fit the network situation in consideration of the number of subscription genres. It is to provide an ACQ / QOR mixed acceptance method and system according to the introduction of number portability that flexibly operates SMSC.

The existing SMSC processed the message by applying the same number translation and process to all receiving station numbers. However, with the introduction of number transfer and number pull schemes, the complexity of message routines has increased, including the acceptance and processing of all network code station numbers. In order to effectively cope with changes in the network, it is necessary to flexibly take message processing routines such as message subscriber information processing according to the number portability of each station number. That is, the QOR routine is applied to the station number with small number portability and the ACQ routine is applied to the station number with high number portability. In addition, the above effect can be obtained by changing only the field data of the SMSC system.

Another object of the present invention is the number portability to reduce the load on the system and network in the situation that the network code station numbers of all operators are introduced into the network when the number portability and number pool is introduced, the network is complicated The present invention provides an ACQ / QOR mixed acceptance method and system.

Another object of the present invention is to flexibly respond to the requirements of the field with minimal changes in the network, when introducing the Number Portability and Number Pool, thereby reducing costs and improving competitiveness It is to provide a method and system for accommodating ACQ / QOR according to the introduction of number portability to secure.

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

3 is a view showing the configuration of the authentication system for each station according to the ACQ / QOR mixed acceptance according to the present invention.

In the system shown in FIG. 3, the ACQ (All Call Query) method and the QOR (Query On Release) method are mixed to provide a short message service according to the introduction of number portability. SMSC can be operated efficiently and flexibly.

Referring to FIG. 3, an authentication system for each station number according to ACQ / QOR mixed acceptance is compared with a system that provides a mobile communication service using only one of a conventional All Call Query (ACQ) method and a Query On Release (QOR) method. By the station number authentication method database 301 may be further included.

Station-specific authentication scheme database 301 may include a station-specific authentication scheme table (401 of Figure 4 below), the station-specific authentication scheme table (401 of Figure 4 below) according to the station number ACQ (All Call Information on whether authentication is to be performed in a Query method or a Query On Release (QOR) method may be stored.

The station number authentication scheme table (401 in FIG. 4 below) will be described in detail with reference to FIG. 4 below.

The subscriber 123 of the terminal 121 subscribes to the service provided by the carrier A (the original carrier) and receives a mobile directory number (MDN) from the carrier A (the original telephone number). After that, the subscription contract with the carrier A (the original carrier) is canceled, and the service provided by the carrier B (the current carrier) is subscribed to, thereby obtaining a new subscriber number (MDN: Mobile Directory Number) from the carrier B (the current carrier) ( Current phone number). However, due to the introduction of number portability, by storing the number porting information of the subscriber station in the number porting database provided by the service provider, the original original phone number can be used as it is even after changing the service provider.

However, in case of providing mobile communication service only by ACQ (All Call Query) method, the number portability database 111 should be queried whether all the numbers are moved or not. Therefore, it puts excessive load on the system. The disadvantage is that you have to invest.

In the case of providing a mobile communication service using only a query on release (QOR) method, a call connection time of a number ported call and a call that is not is different from each other.

Therefore, in the present invention, the SMSC (Short Message Service Center) determines whether to perform authentication processing by the method of ACQ (All Call Query) method or QOR (Query On Release) method according to the station number and QOR (Query On Release) and By adopting ACQ (All Call Query) method mixedly, SMSC can be operated efficiently and flexibly in accordance with the network situation in consideration of the degree of number movement of subscription genre.

That is, when a call request and a short message transmission request are made, the originating network refers to the authentication method table 401 for each station number in FIG. 4 below, or the authentication method for the corresponding station number is an ACQ (All Call Query) method or a QOR (Query On Release) method. After determining the acknowledgment, the call connection and short message are transmitted.

The process of authentication processing in any method of ACQ (All Call Query) method or QOR (Query On Release) method according to station number in SMSC (Short Message Service Center) will be described in detail with reference to FIG. 5 below.

4 is an exemplary diagram of a station-specific authentication scheme table according to ACQ / QOR mixed acceptance according to the present invention.

Referring to FIG. 4, the station number authentication method table 401 according to the ACQ / QOR mixed acceptance may be included in the station number authentication method database 301 of FIG. 3. The station number authentication method table 401 includes a station number (Prefix), an authentication method (Query Method), a signal point of the authentication server (PC [NPS / HLR]), a subsystem number (Subsystem No), a host description (HostName), and the like. May contain information.

Only the network code (011/016/017/018/019) can be known that the called subscriber is a subscriber of the mobile communication provider. Therefore, it is necessary to check the identity of the subscriber through the authentication server. However, in order to minimize the load and maximize the efficiency, the subscriber's authentication procedure of the network is flexibly operated based on the degree of subscriber mobility according to the number system. That is, the station number that does not have large number portability is determined by the other company and authenticated by QOR (Query On Release) method, and the station number with large number portability is authenticated by ACQ (All Call Query) method.

To this end, by determining whether or not the number portability of each station number by quarter and for a certain period of time, set the QOR (Query On Release) method for the station number is less than a specific reference value (for example, the average value), the number shift is the specific reference value For the above station number, the ACQ (All Call Query) method can be set. The set station-specific authentication scheme is stored in the station-specific authentication scheme table 401. The branch, period, and reference values may be variously set.

For example, in the case of 016-301-0965 (outgoing) and 011-411-0976 (incoming), an outgoing short message service center (SMSC) has a station number of the called number '0114' and an authentication method. Since it is ACQ (All Call Query) method, it requests authentication to NPS server whose signal point is H'03, and if it is its own subscriber, it receives an incoming call from its own network and sends it to other company.

The authentication method for each station number according to ACQ / QOR mixed acceptance is illustrated as in FIG. 4, but it is obvious that it may be variously changed according to the change of network environment and the number portability of subscriber.

5 is a flowchart illustrating a process for authenticating by station number according to ACQ / QOR mixed acceptance according to the present invention.

Referring to FIG. 5, an originating exchange (MSC) 109 of the originating network 105 transmits a short message from the originating terminal 103 via a base station (BTS) (not shown) and a base station controller (BSC) (not shown). When receiving the request (S501), the originating terminal 103 and the destination terminal 121 of the home location register (HLR) (not shown) and the visitor location register (VLR) (not shown) in the outgoing network 105 The subscriber information is transmitted to the calling short message service center (SMSC) 107 together with the short message transmission request (S503).

Here, the short message transmission request may include a content of a short message and a contact number, and the subscriber information may include a mobile station identification number (MIN) and a subscriber telephone number corresponding to the destination terminal 121 inputted to transmit the message. (MDN: Mobile Directory Number) and the like.

The call back number may be a mobile identity number (MIN) stored in the calling terminal 103 by default when the short message is input at the calling terminal 103.

When the outgoing short message service center (SMSC) 107 receives the subscriber information and the short message transmission request from the outgoing exchange 109, it uses the mobile station identification number (MIN: Mobile Identity Number) of the destination terminal 121 to determine the station number. The authentication method for each station number is extracted from the authentication method database 301 (S505), and it is determined whether the authentication method corresponding to the called station number is an ACQ (All Call Query) method (S507).

As a result of the determination, if the authentication method is ACQ (All Call Query) method, it is checked whether the destination terminal 121 has moved by using the number movement database 111 (S515).

As a result of the determination, if the authentication method is not an All Call Query (ACQ) method, the authentication method is a QOR (Query On Release) method, so that the authentication method is a destination exchange (that is, an original destination exchange) 119 of the network 117 corresponding to the destination terminal. The call request is transmitted (S509). When receiving a call connection message from the originating exchange 119 in response to the call request (S511), the originating short message service center (SMSC) 107 determines whether the call release message (S513).

In the case of the call release message as a result of the determination, the mobile station proceeds to step S515 and checks whether or not the corresponding destination terminal 121 has moved by using the number movement database 111 (S515).

After executing the above-described process, if the destination terminal 121 is not moved by the number shift determination result, the mobile station identification number (MIN: Mobile Identity Number) of the destination terminal 121 is a received telephone number of the short message. If the destination terminal 121 is a number shift, the subscriber's telephone number (MDN: Mobile Directory Number) of the destination terminal 121 is set as the reception telephone number of the short message.

The outgoing short message service center (SMSC) 107 sets a receiving telephone number according to whether the destination terminal 121 has moved the number and sends the short message (S517).

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.
