Description

METHODS FOR TRANSFERING INFORMATION BETWEEN VISITOR LOCATION REGISTER AND HOME LOCATION REGISTER FOR HOMEZONE SERVICE IN MOBILE NETWORK}

The present invention relates to a method for supporting a homezone service in a mobile communication system, in particular, a visitor location register (hereinafter referred to as VLR) and a home location register (hereinafter referred to as HLR). To design a protocol for passing information between

The rapid development of the economy and information and communication sectors not only diversifies and enhances the user's needs, but also compels operators to create new additional services. Home zone services in mobile networks are part of this effort.

At present, due to the rapid increase in mobile subscribers in Korea and abroad, interest in various new services and intelligent network services of mobile operators is increasing. There are many factors that have contributed to the proliferation of these new services. The development of real-time database processing technology is one example. In addition, the development of No.7 signaling technology, which transmits signal messages separated from traffic, also played an important role.

In general, in mobile networks, IS-41C is a mobile application part (Mobile Application Part: hereinafter referred to as MAP) protocol for delivering messages using application No.7 signaling. I use it.

1 is a diagram showing the configuration of a basic mobile network using the IS-41C.

As shown, it is assumed that the VLR is built in the MSC 300. Communication between the MSC 300 and the BSC 220 is in accordance with the IS-634 standard. The application protocol between the remaining network entities (hereinafter referred to as NEs) uses IS-41C. The HLR 700 is an important NE in the mobile network and is a database that contains all the subscriber's information. The Short Message Service Center (SMSC) is an NE for short message service, and the Authentication Center (AC) is an NE for subscriber authentication processing.

The IS-41C MAP protocol specification defines scenarios of MAP operations that occur between the above NEs (except BSS) for basic call services and supplementary services, as well as the operations and parameters that should be used for those services. It also defines No.7 TCAP as the protocol for the lower layer signaling network.

However, basic call service and supplementary service using IS-41C (see IS-41C standard) are not enough to preempt subscriber's demand. This allows operators to consider the development of newer services.

The home zone service is charged in the same area as the subscriber's predetermined area (also called homezone). If the user leaves the area, the home zone service is charged. It is a service to make. With this service, subscribers do not have to have a landline. For example, if you have registered your home as a home zone, you can make (or receive) your landline phone charges through your mobile phone without having to install a regular landline phone. With the development of these services, operators can expect to convert existing and new subscribers.

Implementing home zone services in mobile networks is difficult with existing IS-41C alone, and requires the addition of functions of several NEs and the development of software.

An object of the present invention is to provide a method for transferring subscriber's HZ information between HLR and VLR for home zone service in mobile network.

According to an aspect of the present invention, there is provided a method for transmitting information between an affiliated location register and a visitor location register in a mobile network capable of home zone service, the first step of transmitting a Qual command message from the affiliated location register to the visitor location register. And a second step of receiving, by the visitor location register, the qualitative command message, updating home zone information, and then sending a response to the affiliated location register, and transmitting a home zone command message from the affiliated location register to the visitor location register. And a fourth process of receiving, by the visitor location register, the home zone command message, updating home zone information, and sending a response to the affiliated location register.

2 is a diagram showing the configuration of a basic mobile network for a home zone service.

Compared to FIG. 1, the location determinination service provisioning center (hereinafter referred to as LDSPC) 800 is added to the NE. Signal network configuration for call control or mobility management between each NE connected to the MSC 300 uses No. 7 signaling. The MAP protocol IS-634 is communicated between the MSC 300 and the BSC 220 by using the MAP protocol IS-41C between the MSC 300 and the NE connected to the MSC 300 except for the BSC 220. Communication between the HLR 700 and the LDSPC 800 is performed by TCP / IP, and the communication between the LDSPC 800 and the Customer Care Center (CCC) 900 also uses TCP / IP. Here, the roles of each NE are the same as those in the existing mobile network. The LDSPC 800 receives customer data, such as subscriber registration and termination, from the CCC 900 and transmits it to the HLR 700. In addition, when receiving subscriber information from the customer center when registering a new subscriber, a home zone list of the corresponding subscriber is generated by referring to a previously created database. In this case, the pre-created database means that the subscriber's location (latitude / longitude) can be predicted in advance, and information of the related base station is made into a database according to each location. The generated home zone list is directly transmitted to the HLR 700 and stored in the subscriber database so that it can be used in future call processing.

25 is a diagram illustrating a home zone MAP simulator matching structure.

When the MSC receives a MAP request related to the HZ service, the MSC recognizes the MAP processing block and transmits data to the simulator (virtual HLR). At this time, the simulator generates the same HZ MAP message (HZList, subscriber HZ information, etc ..) generated by the actual HLR and transmits it to the MAP processing block of the MSC. If such a simulator is installed inside or outside the MSC, the function of the HZ MAP protocol can be verified by the simulator before performing communication with the actual HLR.

FIG. 26 is a diagram illustrating a location registration procedure for a home zone service according to an embodiment of the present invention. FIG. The HZ service call processing that can be provided to the HZ subscriber after actually applying the MAP protocol according to the present invention to the communication between the HLR and the VLR may appear in various ways according to the grade and situation of the subscriber. For example.

The base station BS, which has received a registration message from the terminal MS, generates a Location Updating Request (HZLAI). Upon receiving the location update signal, the MSC / VLR generates a non-register signal {RegNotRQr (HZLAI)} and transmits the signal to the HLR 700 when the subscriber does not have the subscriber information. The HZLAI included in the unregistered signal RegNotRQr is current location information of a subscriber received from the terminal.

The HLR 700 receiving the unregistered signal {RegNotRQr (HZLAI)} compares the first stored HZList (created by the first LDSPC) with the current location information (HZLAI) of the subscriber received from the VLR to determine the location of the current subscriber. Determine whether it is inside or outside HZ area. Then, a registration signal_regnot including home zone in / out information HZ_InOut and subscriber's home zone rating information HZClass is transmitted. Of course, the existing IS-41C MAP parameter is basically included at this time.

After receiving the home zone in / out information (HZ_InOut) and the subscriber's home zone rating information (HZClass), the VLR sends the home zone in / out information (HZ_InOut) to the MSC and checks the subscriber's home zone rating information (HZClass). As a result of the check, when the subscriber is a registered home zone or a home zone and a mobile phone, a home zone request signal {HZREQ (MIN, ESN)} is generated by the HLR 700, and the HZ information of the subscriber from the HLR 700 is generated. Get it and store it in your own database (VLR).

Although not shown, when the HZ information of the subscriber is changed in the HLR 700, the HZ information of the subscriber is updated through the HZDIR. In addition, when there is a request for information of the called subscriber, if there is no subscriber information, the procedure as described above is performed after transmitting the QUALREQ to the HLR 700.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention designs the HZ MAP protocol (operation, parameter) between the VLR (MSC) and the HLR so as to be used to realize the HZ service in the mobile network, so that the HZ information of the HZ subscriber is in real time between the HLR and the VLR. There is an advantage that smooth call processing can be achieved by being updated.
