KR100744287B1 - Method for home zone list update using general call in cdma system - Google Patents

Abstract

According to the present invention, a subscriber registered in a CDMA system must have an HZ list in order to receive a home zone service provided by the CDMA system. The HZ service list is generated by using the information of the subscriber's address (latitude / longitude) and the installed base station information, and the generated HZ list is registered with the HLR and VLR to receive the HZ service. If the HZ list is inaccurate due to the surrounding environment, the actual incoming / outgoing call information of a specific subscriber is collected through the MSC External Network Interface Processor (ENIP) and compared with the existing HZ list by using the collected incoming / outgoing data. It is to optimize the HZ list of existing base stations, and to optimize the existing HZ list of base stations included in the same group.

Home zone service of CDMA system

Description

METHOD FOR HOME ZONE LIST UPDATE USING GENERAL CALL IN CDMA SYSTEM}

 1 is a flowchart of updating an existing home zone list of a subscriber using incoming / outgoing call information according to an embodiment of the present invention.

2 is a general call data file format diagram according to an embodiment of the present invention.

The present invention relates to a home zone (HZ) service in a CDMA system. In particular, when the HZ list of a particular subscriber is incorrect due to the surrounding environment, MSC ENIP (Internal Network Interface Processor) General call in the CDMA system that collects through and optimizes the existing HZ list of the existing base station compared to the existing HZ list by using the collected incoming / outgoing data, and optimizes the existing HZ list of the base stations included in the same group Home zone list update method using a.

In general, CDMA mobile service providers are introducing a new service called HZ (Home Zone) as part of their service differentiation strategy. The HZ service defines HZ Service Class and HZ Service Area for each subscriber. And, it means to provide a differentiated service by making the charge in the HZ area defined above cheaper than the existing mobile phone bill. The subscriber registered in the CDMA system must have an HZ list in order to receive the HZ service. The HZ list is generated by using the address information and the installed base station information when the subscriber is registered. The generated HZ list information is HLR, VLR. You must be registered at HZ to receive the service. However, when the existing HZ list of registered subscribers is inaccurate or the existing HZ list is incorrect due to the surrounding environment, there is a problem that the existing HZ list should be compensated.

Therefore, an object of the present invention is to collect / statute the incoming / outgoing call information of a particular subscriber when the HZ list of a particular subscriber is initially generated incorrectly. The present invention provides a method of optimizing an HZ list of an existing base station by determining a minimum of round trip delay (RTDmin) and an offset value for the RTDmin.

Another object of the present invention is to provide a method of optimizing HZ information of a base station existing in the same group as a base station whose HZ information is changed.

According to an aspect of the present invention, there is provided a home zone (HZ) list updating method using a general call in a CDMA system including an MSC External Network Interface Processor (ENIP), wherein a general call is transmitted from the MSC ENIP. The first process of receiving, collecting and storing as a file and checking whether it is an HZ call, and in the first process, disconnects the connection if it is not an HZ call. And a new minimum of round trip delay (RTDmin) and an offset value for the RTDmin of the base station, which is compared with the existing HZ list when the predetermined number of times or more is specified in the second process, and the determined RTDmin is determined. And determining the RTDmin and the offset value of the RTDmin of the base station included in the same group by using the offset value. A fourth step of updating the HZ list with the new HZ list by the determined value; And a fifth process of receiving the HZ service by transmitting the changed HZ list information of the fourth process to the HLR and the VLR.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention through the reference numerals added to the components of each drawing, it should be noted that the same reference numerals are used even when the same reference numerals are shown on the other drawings to indicate the same components.

In addition, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It will be obvious to those of ordinary skill in the field. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a flowchart of updating an existing home zone list of a subscriber using incoming / outgoing call information according to an embodiment of the present invention.

Therefore, when a specific date and time of the present invention will be described in detail with reference to FIG. 1, all data having a data type of 0,1 among general call data transmitted from the MSC ENIP in step (a) are / users2 / in step (b). Save it as a file named CALL.MMDD in the 1dspc / DATA / ENIP Directory. The file format of the general call data is configured as shown in FIG. 2, and basically, the file of the general call data is composed of one line headline as in (2A) and a plurality of data lines as in (2B), and each line is as follows. Consists of 258 bytes. The structure of each HZ list is as shown in (2c). In step (c), check the HZ signal. In case of the HZ call, the CALL.MMDD file is opened at a specific time determined daily in step (d) to filter and store only the HZ call information during incoming / outgoing calls of all subscribers. In step (e), it is checked whether the changed subscriber and the count number are 100. In step (e), statistical data of at least 100 subscribers having call information is extracted. When the extracted statistical data of the subscriber reaches 100 times, in step (f), a new RTDmin and an offset value for the RTDmin are determined for the existing base station by comparing with the existing HZ list.

    1), determination of new RTDmin value

If -RTDmin <Gen_RTDmin,

 RTDmin = GEN_RTDmin X 0.95 (GEN_RTDmin <400)

       GEN_RTDmin -20 (GEN_RTDmin> 400)

 If -RTDmin> GEN_RTDmin & RTDmin -GEN_RTDmin <30,

  RTDmin = GEN_RTDmin

-RTDmin> GEN_RTDmin & RTDmin-GEN_RTDmin> 30

 RTDmin = GEN_RTDmin-30

    2), determination of new offset value

If -GEN_RTDmax <RTDmin + 80

Offset = RTDmin + 80

If -GEN_RTDmax> RTDmin + 80 & GEN_RTDmax-RTDmin <120

 Offset = GEN_RTDmax

If -GEN_RTDmax> RTDmin + 80 & GEN_RTDmax-RTDmin> 120

Offset = RTDmin + 120

   The new HZ list information determined in the above process and the HZ list information of the existing subscriber are used to determine the newly determined RTDmin and offset values. When the RTDmin and offset values of a specific base station are changed by general call data, the execution program searches the gbts_home table and updates the RTDmin and offset values of the base stations belonging to the same HAGB group as much as the changed values. When the HZ list update operation of the subscriber 100 or more times is completed in the above process, all information of the corresponding subscriber is deleted from the Call_info database.

As described above, the subscriber's incoming / outgoing information is used to update the subscriber's existing HZ list to improve the accuracy of the HZ service by solving the problem of the dissatisfied subscriber due to irregularities in the wireless environment, and according to the change of the HZ list information of the specific base station. Since the HZ list is also changed for the base stations included in the same group, there is an advantage of optimizing the HZ service.
