Method of providing services to the local area for subscribers of mobile phones in the mobile radio communication system

 

The invention relates to a method of providing services to the local area for the purposes of the particular zone to the mobile subscriber and accordingly the monthly fees for various billing for payment for communication services, which are charged in the matter, does the subscriber phone call inside or outside the zone. The technical result is that local area, which is determined using the first measured value and the second measured value in the form of a subsector, is determined by measuring round-trip times from a stationary location in the sector cell cell to the neighboring base stations, which belong to the subscriber, in order to prepare a predefined database of the local area, which includes the first value and the second value. This is achieved by the fact that the measured round-trip times obtained from the specific signal if the portable mobile user terminal generates a request signal for establishing a connection of the call. Then determine whether the subscriber is within the subsector, if the measured value of bilateral delay is between the first value and the second value of bastarrachea the Present invention relates to a local service area, the subscriber's mobile phone in a mobile network. More specifically, the present invention relates to a method for improving the accuracy and performance when providing services to the local area.

The level of technology in the local Service area is the allocation of a given area, known as the "local zone", so that it was possible to use a different rate of payment for the mobile subscriber, depending on whether is or not the subscriber within the local area when establishing a call. Thus, the mobile subscriber can selectively determine the number of different local areas at a specified time when it is moving from one geographical location to another.

If the surroundings of the zone of residence of the subscriber is defined as area services local area, for a subscriber of a mobile phone can be applied to the payment equivalent to the payment for the services of a local wired telephone network. But if the call is made outside the local area, for a subscriber applies a higher rate corresponding to the rate of payment for radiotelephone call.

If the subscriber requests a service in the local area, the boundary of the local area is defined in accordance with various factors such as the position (latitude/longitude) of the base article is tion, characteristics of multipath propagation in the area of the base station and so on.

As shown in Fig.1, the location of the cell the cell is divided into many sectors. Accordingly, the local area can be defined as including the entire area of the cell cell (base station) or one of the sectors. However, the definition of local area service providers is an important parameter from the point of view of the amount of income they can get) is the detection accuracy of the local area. The minimum error occurs when defining the boundaries of local areas due to the expansion of the boundaries of the local area can cost the providers of a significant loss of income. Thus, the ability to recognize the limits of the local area when the subscriber starts (or ends) call within the local area is important from the point of view of raising revenue for service providers.

Summary of the invention Accordingly, the present invention allows to solve problems arising in engineering, to which the invention relates, and the present invention is to create a method of providing services to the local area, which you can more accurately determine the location of booby to solve the above problem, according to the present invention, a method of providing services to the local area, which allows you to associate a given area with a mobile subscriber and pay subscriber accounts on different tariffs for communication services on the basis of, does the subscriber phone call inside or outside the local area. How is that connected many areas with lower payment with a mobile subscriber, and the border areas with low pay is defined as the first measurement value and the second measured value and the first value and the second value is measured based on the average round-trip times from multiple locations within a sector of the cell location of the cell in which is located the subscriber with respect to neighboring base stations, and then prepare a database of the local area, which includes the measured first value and the second value, calculate the two-way signal delay request mobile subscriber to establish a call connection, and determine if the subscriber in the local area if the calculated two-way delay is in the range between the first value and the second value, which is found in Ojen within the local area, the subscriber is informed about if it is located within the local area.

According to another aspect of the present invention, a predefined database of local area stores and found in the control center database.

Fig. 6 depicts an algorithm illustrating the process of identifying local areas performed using a mobile terminal according to a variant implementation etenia presented below.

In the drawings, identical elements are denoted by the same positions, even if they are depicted in different drawings. A detailed description of well-known functions and configurations used here will be omitted for clarity, as it makes the unclear scope of the present invention.

In Fig. 2 shows a view illustrating the concept of a sub-sector that defines the local area, according to a variant implementation of the present invention. The local area can be defined based on the location cell of the cell (base station) or one of the sectors of the cell location of the cell. Local area marked within the sector can be called local area on the basis of subsector (Fig.2).

As shown in Fig.2, sector 2 cell cell 1 is divided, for example, in many sub-sectors 1 to 3. This division sector on various podskornie zone is performed using the two sided delay (DZ). As an example, the division of the sub-sectors 1 and 2 is implemented on the basis of the border Z, and the division of the sub-sectors 2 and 3 is implemented on the basis of the border D. Calculation D and D, which is used to define the different local areas, will be discussed in detail below.

In Fig.3A and 3B prevariety implementation of the present invention.

As shown in Fig.3A, if the position of the subscriber 100 has the specified location, then the part of sector 2 cell cell 10 may overlap part of sector 1 cell cell 11. As shown in Fig.3B, the subscriber's location may overlap two different local areas. Thus, the subscriber 100 is not only sub-sector, which is determined by the boundary DZMAhand the border DZ2minin sector 2 cell cell 10, but he also belongs to the sub-sector, which is determined by the boundary DZMAhand the border DZ1minin sector 1 cell cell 11. Thus, if the subscriber 100 makes a phone call in any of the two sectors, with the subscriber's mobile phone will be charged, the corresponding local call.

Below is a detailed explanation of the calculation process DZ to determine the local area.

If we assume that the definition is circular local area includes a stationary region (for example, rolling around the house of the subscriber), the maximum and the minimum distance between the local area and the neighboring base station can be determined in accordance with the service provider or by the user. At the same time, the minimum distance is the shortest of Rasayana - this is the longest distance among the linear distances from the base station to the external borders of the local area, which is located opposite the internal boundaries of the local area. These distances can be determined using two-way delays (DZ). DZ is a value obtained by dividing the distance by the speed of propagation (i.e., C = 300,000 km/s) and further multiplying the divided value by 2 taking into account the distance that the signal passes in the forward and reverse directions. The base station measures the propagation time of a signal in the forward and reverse directions by measuring the time during which the radio wave radiated from the base station reaches the mobile terminal and returned back to the base station. This can be expressed using the following equation:
Z = 2(D_i/c)
Here i takes the value 1 or 2. D_i is a variable that represents the minimum distance for i=1 and the maximum distance at i=2.

In order to improve the accuracy of the boundaries of local areas using the values of RS, take the following additional steps.

The approximate distance from the base station to the corresponding location can be calculated linear SPM terminal is calculated using a digital signal processor (DSP) of a base station, the value of RS can be obtained by dividing the calculated distance by the speed of propagation and further multiplying the divided value by 2. However, the radio wave is transmitted in the environment with the characteristics of multipath propagation. Thus, the delay time caused by the characteristics of multipath propagation of radio waves that can affect the calculation of RS. The time delay encountered by the signal in such background areas, usually has a similar delay. Thus, in the embodiment of the present invention, values of time delay for different background measured selectively, and their average values measured for the creation of a database that defines an area of reduced payment. The values of the delay time changes depending on different locations, which could be a mobile phone, such as area business district, shopping center, residential or industrial area and so on. Thus, when using the previously defined database, which takes into account the different characteristics of multipath propagation, it is possible to obtain a more accurate value of RS for determining the local area.

In order to polucheniya different values of time delay at a given speed transfer between different locations and their neighboring base stations in a real environment. Then the average value of RS can be obtained in a given location of a mobile phone. As part of attempts to determine the exact value of RS, which is used to indicate areas with low pay, measured another factor to be used when retrieving the test database. Since most users will seek to define their residential area as a local area in order to benefit, thanks to a lower rate of payment on account, a test database is generated by estimating the time during which users are most likely to be in their place of permanent residence. For example, because there is a higher probability that the subscriber is in his house during the period of time between 24: 00 and 06:00, the experimental average value of DZ is measured during this period of time.

In Fig. 4 presents a table that illustrates information database of the subscriber for the services of the local area, according to a variant implementation of the present invention. The database shows that there were two registered subscriber.

As shown in Fig.4, the first subscriber, Mr. Gil-Dong Hong (Gil-dong Hong, who lives in adresi inside of the local area and uses the number 011-779-xxxx number in mobile networks outside their local area. The house of Mr. Hong (Hong) is in the scope of services provided by three neighboring base station. Local area registered by Mr. Hong (Hong), is determined by the area in the range of 16-40 elementary zones fromsector of the base station 1. At the same time, values of 16 and 40 are respectively a minimum value of RS and the maximum value of RS, but the actual distance is in the range 8-20 elementary zones from the base station, because the value of DZ takes into account the full propagation time between the base station and mobile phone. Thus, the local area is in the range of 10-22 elementary zones withsector base station 2, and in the range of 12-24 elementary zones withsector base station 3. In this case, the distance of one elementary zone is 245 m, which is obtained by dividing the distance by the speed of propagation of radio waves 300000 km/s and the modulation frequency 1,2244 MHz multiple access, code-division multiplexing (mdcr).

In Fig. 5 shows an algorithm illustrating the process of identifying local areas, managed directly by the subscriber, according to varianter using certain buttons (for example, *89) of the mobile terminal in order to establish whether it is within a local area, using the mobile terminal MS. Information on the dial corresponding to the above call, is transmitted to the base station BS (operation 51). The base station receives information about dialing and simultaneously computes the value of DZ (operation 52). Then the base station transmits the information about the dial and the calculated value of RS in the switching center mobile communication (operation 53). The switching center of the mobile communication makes a request to search the database in the control center database (ATC) and, in turn, takes the appropriate database from the Department of internal Affairs (step 54 and 55). In this case, for convenience in use ATC as a term that includes a home location register (REM), registered guest location (DDM), module location, the service center (CPU), a customer service center (CSC) and so on. Specialists will clearly perform various operations between REM, DDM, the CPU and CSC, and liaison between the switching center of the mobile communication and UBB.

After that, the base station checks the class of service of the subscriber, the maximum value DZ (Jmach) and minimoose their services to the local area. Then the subscriber can select a service in the local area or both services, which includes home zone and local zone, which is outside the local area.

If the subscriber has registered with the local service zone, and he requests such service, after verifying that the subscriber has the right to use the service of the local area based on the found database, the base station transmits a signal identifying the local area in the mobile terminal through the channel traffic. If the conditions are not met, then the base station transmits the audio signal to identify "no local zone" (57). At this time, the mobile terminal displays the information about what is or is not the current location of the mobile terminal within the local area in order to inform the subscriber (operation 58).

In Fig.6 shows an algorithm illustrating the process of identifying local areas performed by the mobile terminal, according to a variant implementation of the present invention. The process of identifying local zone allows a mobile terminal to identify whether the mobile terminal within the local area, and allows the mobile terminal to automatically display the signal deviations, if Moby is diversified zones (operation 61).

The base station transmits IN (identification number) of a base station and IN the sector in the mobile terminal (operation 62). Then, the mobile terminal determines belongs or not the base station is your local area in accordance with the list of local areas (operation 63), and transmits a request for registration of location, if the base station is owned by a local area (operation 64). The base station receives the request for registration of location and simultaneously calculates DZ (Z) (operation 65). The switching center of the mobile communication transmits a request for registration of location information of the base station and the calculated value of DZ (Z) UB (operation 66). At the same time, UB sends a response, including specific information about the base station on the basis of a database of local areas in the switching center of the mobile communication. That is, receive information corresponding to the maximum value of DZ (Jmach) and the minimum value of DZ (ZMP), which refers to the subscriber (operation 68). The switching center of the mobile communication checks whether the calculated value of DZ (Z) in the range between the maximum value DZ (Jmach) and a minimum value of RS (ZMP) based on a given database (69). If the conditions of the implementation of the C channel traffic (70A), whereas if the conditions are not met, then the mobile switching center transmits the communication signal identification is not local to the area in the mobile terminal (operation 70b). Then, the mobile terminal detects, is your current location within a local area to provide information to the subscriber (operation 71).

As described above, the present invention has the advantage that it allows more accurate and efficient service to the local area by determining the location of the mobile terminal within the local area, by comparing the specified range of the local area on the basis of the sector with the current location of the mobile terminal.

Although the present invention has been described with what is presently considered the most practical and preferred embodiment, it should be understood that other modifications can be made without deviation from the scope of the invention.

Thus, the invention should not be limited to disclosed the embodiment, but should be determined by the scope of the attached claims and their equivalents.
