Description

Apparatus and Metood for registering location of Mobile Terminal}

The present invention relates to an apparatus and a method for registering a location of a mobile terminal. More particularly, the present invention relates to a location registration of a mobile terminal for performing efficient location registration for a plurality of mobile terminal users who are moving in a vehicle at a high speed. An apparatus and method are provided.

In general, a mobile communication system consists of cells divided into a plurality of base stations (BTSs), and the base stations are controlled by a mobile switching center (MSC) so that a mobile station (or mobile terminal) is called a cell. It allows you to make continuous calls while moving between them.

This is accomplished by storing the location information of the mobile station in the home location register (HLR) and the visitor location register (VLR), which are mobile station information storage devices of the mobile communication system. The subscriber's information is stored in the home location register in the area where the service is applied.

When the mobile station moves, the mobile station registers the location information of the mobile station in the visitor location register to which the mobile station belongs, and informs the home location register of the mobile station so that when a call is received from the outside, the home location register locates the mobile station. Only the mobile station knows which visitor location registers it is in, so that the incoming call can be successfully performed.

FIG. 1 is a diagram for explaining a location registration method of a mobile station according to the prior art. As shown in the figure, the mobile station 11 has a corresponding zone (ZONE 1) 13 of a visitor location register (VLR1) 12. ), When moving to the corresponding zone (ZONE 2) 15 of the visitor location register (VLR2) 14, the visitor location register 14 receives a location registration request message from the mobile station 11. Receives and transmits it to the home location register (HLR) 16.

The home location register 16 deletes the location information of the visitor location register 12 previously stored, and requests the visitor location register 12 to delete the location registration information of the mobile station 11.

When the registration deletion request response is received from the visitor location register 12, the home location register 16 sends a location registration request response message to the new visitor location register 14, and the location of the mobile station 11 is updated. do.

Looking at the standard of IS-95 A / B which constitutes the current mobile communication system, the following 9 methods are used in parallel for the registration method of the mobile station.

① Power Up Registration

② Power down registration

③ Timer Based Registration

④ Distance Based Registration

⑤ Zone Based Registration

⑥ Registration by base station command (Ordered Registration)

⑦ Implicit Registration

⑧ Traffic Channel Registration

⑨ Parameter change registration of mobile station

According to the ⑤ Zone Based Registration method among the nine methods, whenever a mobile terminal moves and passes a location boundary between a cell and a cell, its location is transmitted through a base station of the corresponding cell area. This means that when a large number of mobile terminal passengers ride on a public transport vehicle such as a bus, train, and / or subway, and move quickly, the multiple mobile terminals attempt to register a location at almost the same time every time the location boundary passes. As a result, the instantaneous processing load of the mobile communication network increases and interference propagation due to mutual collision also increases, which causes a problem of degrading call quality.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is that when a passenger carrying a mobile terminal rides on a public transportation vehicle, the position registration of the mobile terminal is delegated to a specific device mounted on the vehicle during the riding period. It is an object of the present invention to provide an apparatus and method for registering a location of a mobile terminal to efficiently perform location registration.
