Description

A Method for Realizing Special Charging in Border Areas of Mobile Intelligent Networks

technical field

The invention relates to mobile intelligent network technology, in particular to a method for realizing special charging in the area boundary area of the mobile intelligent network.

Background technique

As shown in Figure 1, the GSM system is mainly composed of three parts: switching subsystem (NSS), wireless base station subsystem (BSS), and mobile station (MS). Switching Subsystem (NSS) includes Mobile Services Switching Center (MSC), Visitor Location Register (VLR), Home Location Register (HLR), Authentication Center (AUC) and Mobile Equipment Identity Register (EIR). The wireless base station subsystem (BSS) includes a base station controller (BSC) and a base transceiver station (BTS). A mobile station includes a mobile terminal and a subscriber identity card (SIM). The wireless base station subsystem is controlled by the MSC, communicates with the mobile station, and mainly completes functions such as radio transmission and reception and wireless resource management.

BTS and mobile station (MS) communicate by radio. From the perspective of radio coverage area, the smallest indivisible area of GSM is the area covered by a base station (omnidirectional antenna) or a sector antenna (BTS) of a base station, called For the cell (Cell). Each cell is identified by a Cell Global Identity (CGI). Several cells form a location area (LAI). The location area is set by the GSM network operator and may be related to one or more BSCs, but it only belongs to one MSC, that is, one location area is composed of multiple cells under the control of one MSC; A location area is identified by a location area identifier. A mobile station (MS) moving within a location area does not update location information in the MSC/VLR controlling the location area. An MSC service area is composed of the area covered by all the cells under its jurisdiction, which can be divided into one or several location areas.

The mobile intelligent network is a network that introduces intelligent network functional entities into the mobile network to complete the intelligent control of mobile calls. It is the combination of existing mobile network and intelligent network. Transform the switching center of the mobile network into an SSP service switching point, and connect the underlying mobile network with the high-level intelligent network (SCP, SMP, SCE, SMAP, etc.), so as to realize the separation of mobile switching and business, forming a mobile intelligent network .

With the support of No.7 signaling network and large-scale centralized database, the mobile intelligent network separates the switching function and control function of the network, and concentrates the control functions originally located in each end office switch to the newly established functional components— —On the intelligent network service control point composed of small and medium-sized computers, while the original switch only completes the basic connection function.

The overall structure of the mobile intelligent network system is shown in Figure 2. It generally consists of a service switching point (SSP), a service control point (SCP), an intelligent peripheral (IP), a service management system (SMS), and a service creation environment (SCE), etc. It consists of several parts. The SSP is the connection point connecting the existing mobile network and the intelligent network, and provides the function of accessing the intelligent network. SCP is the core component of the intelligent network. It stores user data and business logic. Fees, send call control instructions to SSP, so as to realize various intelligent calls. IP is a special resource to assist in the completion of intelligent services, and usually has various voice functions, such as voice synthesis, playing recorded notifications, receiving dual-tone multi-frequency dialing, voice recognition, and so on. SMS is composed of computer systems and generally has five functions, namely, business logic management, business data management, user data management, business monitoring and business volume management. The function of SCE is to generate new business logic according to the needs of customers.

The SCP is the core of the mobile intelligent network, loaded with business logic and user data. When a mobile intelligent network user initiates a call or is called, the MSC/SSP reports to the SCP to start DP (IDP) signaling, triggering the mobile intelligent service on the SCP, and the call process will be controlled by the SCP. The basic process of SCP controlling calls is as follows: after a call is triggered to SCP, SCP starts intelligent service logic and performs basic call processing (such as: analyzing calling and called numbers, etc.); searching user data for call authentication and analyzing user data Account validity; after judging that the call is valid, the MSC/SSP is required to connect the call and perform billing; finally, when the user hangs up, the control process in the SCP ends, and the control of a call is completed.

The billing of the mobile intelligent service is to obtain the area code according to the parameter analysis in the IDP signaling, and use it as the area code of the place visited by the mobile station, and as the basis for billing. Specifically, in the calling process, the area code of the mobile station's visiting place is obtained according to the analysis of the Location Number parameter item of the IDP signaling; The area code of the place.

The billing rates of mobile smart services are mainly divided into the following parts: basic call charges, roaming charges, long-distance charges, and surcharges.

The most commonly used billing rules for mobile smart services are as follows:

1. When the mobile station is calling

Communication fee = basic call fee + [roaming fee] + [long-distance fee from the calling place to the called place]

Explanation: When the area code of the calling place is different from the area code of the calling place, the roaming fee will be charged; only when the area code of the calling place is different from the area code of the called place, the long distance fee will be charged When the caller supports the same city exception, if the calling place is the same as the called place, no long-distance fee will be charged.

2. When the mobile station is called

Communication fee = basic call fee + [roaming fee] + [long-distance fee from the called place to the called place]

Explanation: When the area code of the called place is different from the area code of the called place, the roaming fee will be charged; only when the area code of the called place is different from that of the called place, the long distance fee will be charged When the area code of the called place is the same as the area code of the calling place, no long-distance fee will be charged.

The mobile intelligent service provides flexible billing methods. When the mobile station is the calling party and the called party, the basic call charges, roaming charges, long-distance charges, and surcharges can be different; some billing items can also be excluded, for example: if One-way billing, the mobile station is free when called. Mobile communication operators may call the basic fee and the roaming fee together the basic fee during specific operations, but the basic call fee charged when the mobile station is roaming is different from the basic call fee charged when the mobile station is not roaming. It can be seen that the roaming area of the mobile station is directly related to the final billing.

Currently existing mobile intelligent services include: prepaid service (PPS), family number service (FNS), mobile virtual private network service (VPMN), and regional time-sharing service (CTD), etc.

The current billing of the mobile intelligent service is to obtain the area code according to the parameter analysis in the IDP signaling, and use it as the area code of the place visited by the mobile station, and as the basis for billing. Specifically, in the calling process, the area code of the mobile station's visiting place is obtained according to the analysis of the Location Number parameter item of the IDP signaling; The area code of the place. The Location Number parameter in the IDP signaling reported by the MSC/SSP and the Vlr-number parameter item of the LocationInformation are allocated by the MSC/SSP according to the base station connected to the mobile station. Usually, one MSC/SSP serves only one area, and the visited area number corresponding to the Location Number parameter reported by IDP and the Vlr-number parameter item of Location Information is the same. Under special circumstances, one MSC/SSP can also serve multiple adjacent areas according to needs, and the base stations under the jurisdiction of one MSC/SSP are respectively installed in several adjacent areas, so that one MSC/SSP can provide services for multiple areas. For service, MSC/SSP will group base stations serving different regions, and the visited area numbers corresponding to the Location Number parameter of IDP and the Vlr-number parameter item of Location Information may be different. Therefore, the actually corresponding area of the area code of the mobile station's visiting place analyzed during the billing of the mobile intelligent network is composed of the coverage area of a group of base stations BTS under the jurisdiction of one MSC/SSP. However, the coverage area of a base station BTS is determined by the coverage area of radio signals, and the coverage area of adjacent base station BTSs overlaps. Therefore, the area determined by the coverage area of a base station BTS cannot completely match the actual geographical area of the area.

Generally, mobile station users can only understand and agree with the geographical area actually corresponding to the area, and think that the billing of the mobile station should be charged according to the area actually visited by the mobile station; it is difficult for mobile station users to accept mobile communication operators because of technical reasons. The area code of the place visited by the mobile station can only be determined by the coverage of the base station. Especially in the border area of two or more adjacent regions, it is usually covered by radio signals of base stations belonging to different regions, and the mobile station generally automatically selects a base station for communication connection. In this way, although the mobile station is in its home area, it is considered by the mobile intelligent network system to roam to another area, and it will be billed according to the roaming of the mobile station to another area. From the above, it can be seen that the billing of the mobile station is directly related to its roaming area, so the current mobile intelligent network system has the following problems: in the area border area, the mobile intelligent network obtains the wrong mobile station visiting area code due to technical reasons, and incorrect information occurs. Reasonable billing. Usually, the communication fee for a mobile station to call its home area in its home area is much lower than the communication fee for a mobile station to roam to another area to make a call to its home area. This kind of erroneous analysis of the mobile station's access to the area code in the area border area is easy to overcharge the communication fee, and it is easy to cause complaints from users.

Contents of the invention

The purpose of the present invention is to provide a method for realizing the special billing in the border area of the mobile intelligent network, so as to solve the problem that the mobile intelligent network obtains the wrong mobile station visiting area number due to technical reasons in the border area of the area, and unreasonable calculation occurs. fee.

The present invention comprises the following steps:

A. The mobile intelligent service obtains the current location information of the calling or called user from the received Initiation Detection Point (IDP) signaling or the home location register;

B, the mobile intelligence service logic searches the regional boundary area table that stores the location information of the divided area boundary area on the service control point according to the current location information of the user, to judge whether the user is in the boundary area of the area;

C. The mobile intelligent service performs special charging treatment for users in the area border area.

According to the method above:

The region boundary area table is pre-established on the service control point in the form of database or memory.

The area boundary area table is defined in units of cells or location areas.

Defining the area boundary area table in units of cells is to divide the cell whose radio signal of the base station covers a certain area boundary area into the area boundary area of one or more areas near the cell. Defining the area boundary area table with the location area as the unit is to divide the location area in which the radio signal of the base station covers a certain area boundary area in the location area into the area boundary area of one or more areas near the location area.

In the cellIdOrLAI item of the Location Information parameter of the signaling in the Initiation Detection Point (IDP) signaling, the user's location information is when the mobile intelligent service user initiates a call or is called, by the Mobile Switching Center (MSC)/Service Switching Point ( SSP) written.

The mobile intelligent service obtains the current location information of the calling or called user from the home location register, including steps:

a, the mobile intelligent service logic on the service control point (SCP) sends the information query (ATI) signaling at any time to the home location register (HLR);

b. After the Home Location Register (HLR) receives the ATI, it sends a Subscriber Information (PSI) signaling to the MSC;

c. The mobile intelligence service logic obtains the latest location information of the mobile station, and fills the information into the cellIdOrLAI item of the Location Information parameter of the message and returns it to the service control point (SCP).

The location information is a global cell identification code or a location area identification code.

The special charging means that when the user is in the boundary area of one or more regions, the user is charged at a charging rate different from the normal charging rate.

The special charging means that when the user is in the boundary area of one or more regions, the user is charged according to the region with the lowest charging rate.

The present invention defines the boundary area for the region, so that the service control point (SCP) of the mobile intelligent network can judge whether the communication of the mobile station is in the boundary region of the region, and realizes the communication between the service control point (SCP) of the mobile intelligent network in the boundary region of the region The mobile station of the mobile station carries out special billing, thereby solving the problem of unreasonable charging when the user registered for the mobile intelligent network service uses the mobile station to communicate in the border area of the region.

Detailed ways

Because the radio signal coverage of the base station (BTS) of the mobile switchboard (MSC) has overlapping parts, so in the border area of two or more adjacent areas, it will be covered by the base station signal of the MSC belonging to different areas. A mobile station in a region's border may register with a base station in an adjacent region and communicate through an MSC in the adjacent region. In this way, when the service control point (SCP) of the mobile intelligent network charges the communication of the mobile station, it charges according to the roaming of the mobile station to the adjacent area, instead of charging according to the area where the mobile station is actually located, so that a billing error occurs , may overcharge the communication fee. This happens frequently especially for users who live or work in district border areas.

The invention defines a regional boundary area table on the service control point of the mobile intelligent network, and stores the position information of the divided area boundary area in the table. The intelligent service obtains the current location information of the calling or called user from the received message, and the mobile intelligent service logic uses the location information to search the area boundary area table to determine whether the user is in the area boundary area; if the mobile user In one or more regional boundary areas, the user is subjected to special charging processing, otherwise, the user is subjected to normal charging processing. The present invention will be described in detail below.

On the service control point of the mobile intelligent network, a region border area table can be defined in a database or memory to divide the region border areas. The region boundary area table can be defined in two corresponding ways, taking cells as units or location areas as units.

The method of defining the region boundary area table in units of cells is as follows:

The boundary area of a region is defined with a cell (Cell) as the smallest unit, and the cell whose radio signal of the base station covers the boundary area of a certain area is classified into the boundary area of the area, even if the base station is installed in another area or belongs to an MSC/SSP in another area. Since each cell is identified by a global cell identity (CGI), the area border area table can be defined in a way that the global cell identity corresponds to the area code. Since the coverage of the same cell (Cell) may span multiple adjacent areas, the same cell (Cell) may correspond to border areas of different areas. For MSC/SSP that has been defined as belonging to a certain region, it is not necessary to define the cells (Cells) that belong to a certain region in the boundary region table of the region, but only define the cells (Cells) that do not belong to a certain region in the boundary region table of the region , which is equivalent to the extended boundary area defining the region.

The structure of the cell identification code is:

3 digits 2 digits up to 16bit up to 16bit

MCC MNC LAC CI

Namely: CGI=MCC+MNC+LAC+CI

MCC = Mobile Country Code.

MNC = Mobile Network Code.

LAC = Location Area Code, which is a two-byte integer.

CI = cell number, which is a two-byte integer.

Both LAC and CI are 2-byte integers up to 65536, and 5 digits are required to convert them into numeric characters. Each cell identification code can uniquely represent a cell.

As shown in Figure 3, the cell Cell_A1_1 belonging to area A actually covers the boundary area of A/B/C, and Cell_A2_3 actually covers the boundary area of A/B; the cell Cell_B1_1 belonging to area B actually covers the boundary area of A/B/C. B/C three-region boundary area, Cell_B1_2 actually covers the A/B two-region boundary area, cell_B2_1 actually covers the B/C two-region boundary area; Cell_C1_1 belonging to C area actually covers the A/B two-region boundary area, Cell_C1_2 It actually covers the boundary area of A/B/C three regions.

Each cell in Figure 3 has a unique cell identification code. An example of the regional boundary area table defined in units of cells is as follows:

The boundary area of region A can be represented by a collection of the following correspondence records:

(A area code->Cell_A2_3 cell identification code, A area code->Cell_A1_1 cell identification code, A area code->Cell_B1_1 cell identification code, A area code->Ce[1_B1_2 cell identification code, A area code->Cell_C1_1 cell Identification code, A area code -> Cell_C1_2 cell identification code)

The range of the boundary area can also be set to be larger, and Cell_A2_1, Cell_A2_2, Cell_B1_3, and Cell_C1_3 are also defined as the boundary area of the A region. Specifically which cells are included in the boundary area of a region is configured by the mobile communication operator.

It is also possible to not register the cells originally belonging to area A in the boundary area table of area A, and only define the extended boundary area records of area A, which can be simplified to the extended boundary area table of area A, which can be recorded by the following correspondence Collection means:

(A area code->Cell_B1_1 cell ID, A area code->Cell_B1_2 cell ID, A area code->Cell_C1_1 cell ID, A area code->Cell_C1_2 cell ID)

Similarly, the boundary area of region B can be represented by a collection of the following correspondence records:

(Area B code->Cell_B1_1 cell ID, B area code->Cell_B1_2 cell ID, B area code->Cell_A1_1 cell ID, B area code->Cell_B2_1 cell ID, B area code->Cell_B2_3 cell ID , B area code->Cell_C1_2 cell identification code)

The method of defining the area boundary area table in units of location areas is as follows:

A location area (LAI) composed of several cells (Cell) defines the area boundary area in units of location area, and divides the location area where the radio signal of the base station in the location area covers a certain area boundary area into the area boundary area, even if the location Districts belong to MSC/SSPs in other districts. Since each location area is identified by a location area identification code, the area boundary area table can be defined in a way that the location area identification code corresponds to the area code. The base station coverage of the same location area may span multiple adjacent regions, so the same location area may correspond to border areas of different regions. For the MSC/SSP that has been defined as belonging to a region, it is not necessary to define the location areas that belong to the region's border area table, but only define the location areas that do not belong to the region into the region's border area table. At this time, it is quite An extended boundary area in a defined area. The structure of the location area identifier is:

3 digits 2 digits up to 16bit

MCC MNC LAC

Namely: LAI=MCC+MNC+LAC

MCC = Mobile Country Code.

MNC = Mobile Network Code.

LAC = Location Area Code, which is a two-byte integer.

The maximum value of LAC is 65536, and it needs 5 digits to represent it when it is converted into a numeric character.

Each location area identification code can uniquely represent a location area.

The location area identification code is the first three parts of the cell identification code structure, that is, CGI=LAI+CI.

As shown in Figure 4, assume that Cell_A1_1 and Cell_A3_1 form a location area LAI_A1; Cell_A2_1, Cell_A2_2, Cell_A2_3, and Cell_A6_1 form a location area LAI_A2; Cell_A4_1 and Cell_A5_1 form a location area LAI_A3.

Cell_B1_1, Cell_B1_2, and Cell_B1_3 form a location area LAI_B1; Cell_B2_1, Cell_B2_2, and Cell_B2_3 form a location area LAI_B2. Cell_B3_1 and Cell_B4_1 form a location area LAI_B3.

Cell_C1_1, Cell_C1_2, and Cell_C1_3 form a location area LAI_C1. Cell_C2_1, Cell_C3_1, and Cell_C4_1 form a location area LAI_C2.

As shown in Figure 4, the location area LAI_A1 belonging to region A actually covers the boundary area of A/B/C; the location area LAI_A2 belonging to region A actually covers the boundary area of A/B; The location area LAI_A3 actually only covers area A. The location area LAI_B1 belonging to region B actually covers the boundary area of A/B/C; the location area LAI_B2 belonging to region B actually covers the boundary area of B/C; the location area LAI_B3 belonging to region B actually covers Only covers area B. The location area LAI_C1 belonging to area C actually covers the border area of A/B/C; the location area LAI_C2 belonging to area C actually only covers area C.

An example of the area boundary area table defined in units of location areas is as follows:

The boundary area of region A can be represented by a collection of the following correspondence records:

(A area code->LAI_A1 location area identification code, A area code->LAI_A2 location area identification code, A area code->LAI_B1 location area identification code, A area code->LAI_C1 location area identification code)

It is also possible to not register the location area belonging to A region in the boundary area table of A region, and only register the location area not belonging to A region in the boundary area table of A region, which can be simplified as the extended boundary of A region The region table can be represented by a collection of the following correspondence records:

(A area code->LAI_B1 location area identification code, A area code->LAI_C1 location area identification code)

Similarly, the boundary area of region B can be represented by a collection of the following correspondence records:

(Area B code -> LAI_A1 location area code, B area code -> LAI_A2 location area code, B area code -> LAI_B1 location area code, B area code -> LAI_B2 location area code, B area code -> LAI_C1 location area identifier)

The advantages and disadvantages of the two definition methods are compared:

The advantage of defining the area boundary area table in units of cells is that the division of the area boundary area is more precise, and it is possible to avoid dividing cells that do not cover the boundary of a certain area into the boundary area of the area. The disadvantages are: 1. The amount of data that needs to be defined is too large; 2. The location information is not updated because the mobile station moves between different cells in the same location area, which may cause the cell information obtained by the called process to be inaccurate.

The advantages of defining the regional boundary area table with the location area as the unit are: 1. The amount of data that needs to be defined is small; 2. When the mobile station moves between different location areas, the location information will be updated in time, and the SCP of the mobile intelligent network can accurately obtain the location. district information. The disadvantage is that the division of the area border is not very accurate, and a large number of cells that do not cover the border of a certain area may be divided into the border area of the area.

In fact, the location area identification code is the first three parts of the cell identification code mechanism, and the location area is composed of multiple cells.

The mobile communication operator can choose one of the two methods for defining the regional boundary area table according to the actual situation.

Determine whether the mobile station communication occurs within the area boundary area:

Obtain the current global cell identity code and location area identity code information of the mobile station

When a user of the mobile intelligent service initiates a call or is called, the MSC/SSP triggers the mobile intelligent service, and puts the current global cell identification code and location area identification code information of the mobile station in the Location of the start detection point (IDP) message sent to the SCP. In the cellIdOrLAI item of the Information parameter, the intelligent mobile service can obtain the global cell identity code and the location area identity code of the current location of the mobile station from the IDP message.

If the MSC/SSP version cannot fill in the mobile station global cell identity code and location area identity code information in the cellIdOrLAI item of the Location Information parameter of the IDP message, then the mobile intelligent service logic on the SCP sends an Any Time Interrogation to the HLR , ATI) signaling, after receiving the ATI, the HLR sends the user information PSI signaling to the MSC, obtains the latest cell location information of the mobile station, fills it in the cellIdOrLAI item of the Location Information, and returns it to the SCP. For the signaling flow of this process, please refer to the "Signaling Flowchart for Obtaining the Latest Location Information of the Mobile Station from SCP Sending ATI" as shown in Figure 5; Table of signaling parameters for information".

Determine whether the mobile station is in the area border area

When defining the area boundary area table in units of cells, the mobile intelligent service logic checks the area boundary area table defined earlier in the database or memory according to the current global cell identification code of the mobile station. If no corresponding area code is found, it means that the mobile station is not within the border area of the area, and it will be handled as normal charging. If the corresponding area code is found, it means that the mobile station is in the area boundary area; according to the definition of the area boundary area, a cell may be the boundary area of multiple areas at the same time, so it is possible to find multiple area codes, indicating that the mobile station is in multiple areas. within the region border area. Special billing treatment is performed for the communication of the mobile station within the border area of the region.

When the area boundary area table is defined in units of location areas, the mobile intelligent service logic checks the area boundary area table previously defined in the database or memory according to the current location area identification code of the mobile station. If no corresponding area code is found, it means that the mobile station is not within the border area of the area, and it will be handled as normal charging. If the corresponding area code is found, it means that the mobile station is in the area boundary area; according to the definition of the area boundary area above, one location area may be the boundary area of multiple areas at the same time, so it is possible to find multiple area codes, indicating that the mobile station is in multiple areas. within the border area of a region. Special billing treatment is performed for the communication of the mobile station within the border area of the region.

Special billing treatment for mobile station communications within the border area of the region:

1. According to the principle of the lowest rate, reset the visiting place of the mobile station according to the main visited place and the belonging place

The most commonly used billing rules for mobile smart services are as follows:

1. When the mobile station is calling

Communication fee = basic call fee + [roaming fee] + [long-distance fee from the calling place to the called place] Explanation:

When the area code of the calling place is different from the area code of the calling place, the roaming fee will be charged.

When the area code of the calling place is different from the area code of the called place, long-distance charges will be charged.

When the caller supports the same-city exception, if the calling place is the same as the called place, no long-distance charges will be charged.

2. When the mobile station is called

Communication fee = basic call fee + [roaming fee] + [long-distance fee from the called place to the called place]

illustrate:

When the area code of the called place is different from the area code of the called place, the roaming fee is charged.

When the area code of the called place is different from the area code of the called place, long-distance charges will be charged.

When the area code of the called place is the same as the area code of the calling place, no long-distance charges will be charged.

At present, the billing of the mobile intelligent network has a problem in the region boundary area. Because the base station signal covers cross-regions, the SCP cannot correctly obtain the mobile station's visiting area number, which may lead to overcharging and cause user complaints. If the user is in the boundary area of one or more regions, according to the principle of the lowest rate, if the region where the mobile station is in the communication has the lowest rate, then set the mobile station's visit place as this region, and the mobile station is based on the location of the mobile station. Charges are made within the boundaries of the region.

According to the common billing rules above, examples of billing options in various situations are as follows: Case 1 The home of the mobile station is region A, and it is billed as a calling party Preconditions 1. The mobile station is connected to the base station in area A; 2. The current cell (or location area) of the mobile station is defined as the boundary area of the three areas A, B, and C at the same time; 3. The called party (fixed phone or mobile station) The place of attribution is B area. Billing method 1 As the mobile station is currently in area A, no special billing treatment for the area boundary area: call charge = basic call charge + long-distance charge from the calling area A to the called home area B Billing method 2 Charge according to the current location of the mobile station in area B: call charge = basic call charge + roaming charge Billing method 3 Billing is based on the current location of the mobile station in area C: call charges = basic call charges + roaming charges + long-distance charges from the calling area C to the called home area C billing options Generally, roaming charges are lower than long-distance charges, so it can be seen that billing method 2 has the lowest billing rate. Therefore, billing method 2 is selected, and the visiting location of the mobile station is set to B area. Case 2 The home of the mobile station is region A, and it is billed as a calling party Preconditions 1. The mobile station is connected to the base station in area A: 2. The current cell (or location area) of the mobile station is defined as the boundary area of the three areas A, B, and C at the same time 3. The called party (fixed telephone or mobile station) belongs to area D; 4. The called party has not roamed to areas A, B, or C; or the called party has roamed to areas A, B, or C, but the service does not consider the same city special case. Billing method 1 As the mobile station is currently in area A, no special billing treatment for the area boundary area: call charge = basic call charge + long-distance charge from the calling area A to the called home area D Billing method 2 Billing is based on the current location of the mobile station in area B: call charges = basic call charges + roaming charges + long-distance charges from the calling area B to the called home area D Billing method 3 Charge according to the current location of the mobile station in area C: call charge = basic call charge + roaming charge + long-distance charge from the calling area C to the called home area D billing options It can be seen that billing method 1 has the lowest billing rate. Therefore, the billing method 1 is selected, and the mobile station visits area A, and no special billing processing is performed for the area border area. Case 3 The home of the mobile station is region A, and it is billed as a calling party Preconditions 1. The mobile station is connected to the base station belonging to area A; 2. The current cell (or location area) of the mobile station is defined as the boundary area of the three areas A, B, and C at the same time; 3. The called mobile station belongs to area D ;4. The called party roams to area B, and the service considers the special case of the same city. Billing method 1 As the mobile station is currently in area A, no special billing treatment for the area boundary area: call charge = basic call charge + long-distance charge from the calling area A to the called home area D Billing method 2 Charge according to the current location of the mobile station in area B: call charge = basic call charge + roaming charge.

Therefore, billing method 1 is selected, and the visiting location of the mobile station is set to A region. Case 6 The home of the mobile station is region A, and it is charged for the called party Preconditions 1. The mobile station is connected to the base station belonging to area B: 2. The current cell (or location area) of the mobile station is defined as the boundary area of the three areas A, B, and C at the same time: 3. The calling party (fixed phone or mobile station) The place of attribution is D area. billing method l According to the current location of the mobile station in area A: call charge = basic call charge Billing method 2 Billing is based on the mobile station being currently in area B, and no special billing treatment for area border areas: call charges = basic call charges + roaming charges + long-distance charges from the called area B to the called home area A Billing method 3 Billing is based on the current location of the mobile station in area C: call charges = basic call charges + roaming charges + long-distance charges from the called area B to the called area A billing options It can be seen that billing method 1 has the lowest billing rate. Therefore, billing method 1 is selected, and the visiting location of the mobile station is set to A region.

Note: The billing options listed above in various situations can be selected by mobile communication operators according to actual needs. In addition, there are still many situations that are not listed and dealt with. The above principles and methods can be referred to and determined by mobile communication operators according to actual needs.

2. Set special rates for mobile station communications within the border area of the region

The mobile intelligent service logic method judges that the mobile station is currently in the boundary area of a certain area or some areas, and then uses a set of special charging rules different from the "general charging rules that the mobile station is not in the area boundary area". Set the basic fee, roaming fee, long-distance fee, etc. One or more or all of the rates can be set to be more favorable than the rates of the corresponding items in the general billing rules, give users a certain amount of preferential compensation, and publicize it to users, so as to achieve the purpose of satisfying users and no longer complaining .

Through the method provided by the present invention, the mobile phone operator can carry out special billing treatment for the mobile station communication in the area border area according to the needs, or give the mobile station communication billing preference in the area border area, thereby avoiding charging in the area border area. User complaints caused by overcharging user communication fees.
