no. 1 Embodiment approach

[0038] Hereinafter, a first embodiment of the present invention will be described with reference to the attached drawings for the sake of example. FIG. 1 is a diagram conceptually showing the configuration of a location registration system in this embodiment. As shown in FIG. 1 , the location registration system 1 includes location management devices 20 , 30 , 40 , and 50 and mobile devices 60 , 70 , and 80 . In addition, the location registration device 10 and the location management devices 20, 30, 40, and 50 are wired to each other so that signals can be transmitted and received. The location management devices 20, 30, 40, and 50 can communicate with the mobile machines 60, 70, and 80 respectively via a base station (not shown). In addition, the step numbers described in FIG. 1 are the same as the step numbers described later in the operation description (refer to Figure 6 ~ Figure 9 )Corresponding.

no. 2 Embodiment approach

[0087] Next, refer to Figure 10 ~ Figure 14 A second embodiment of the present invention will be described.

[0088] In the location registration system 1 according to the first embodiment, the location management device estimates the transfer destination using the movement state detected by the mobile device. On the other hand, in the location registration system 2 in the second embodiment, it is assumed that the mobile terminal estimates the transfer destination by itself, and notifies the location management device of the estimation result.

[0089] Figure 10 It is a block diagram showing the functional configuration of the location registration system 2 in the second embodiment. The configuration of the location management device 120 is the same as that of the location management device 20 described in detail in the first embodiment, except that it does not include a transfer destination estimation unit and a transfer destination estimation reference table. The mobile...

Abstract

PURPOSE: A mobile terminal, a location management apparatus and a location registration method are provided to save communication resources in a situation that a large amount of local location registration requests are generated within a short time such as a commuter subway or train in a downtown area. CONSTITUTION: A mobile unit(60) transmits detected results of a movement direction and speed to a location management unit(20). The location management unit(20) estimates a performing area of the mobile unit(60) based on the detected results and transmits area identification information, namely, the estimation result, as a location registration request to a location registration unit(10). The location registration unit(10) updates a location of the mobile unit(60) in a registration location DB, determines an area, namely, a transmitting place of a location registration response, and transmits it. Upon receiving the location registration response, a location management unit(30) transmits the location registration response to the mobile unit(60) as a performing area of the mobile unit(60). By doing that, the mobile unit(60) is informed that transmission of the location registration request by the mobile unit(60) is not necessary, and thus, transmission of the location registration request is prevented in advance.

Description

technical field [0001] The present invention relates to a mobile terminal, a location management device, a location registration system and a location registration method. Background technique [0002] Conventionally, in communication using a mobile terminal such as a mobile phone or a PHS (Personal Handyphone System), it is necessary to perform a process of registering the current location of the mobile terminal on the network side. The current location of the mobile terminal is determined based on, for example, an area composed of a plurality of cells or identification information of a single cell. Usually, when the mobile terminal moves and changes the communication area, the location registration of the mobile terminal is performed every time the change occurs. In this way, the device on the network side must always grasp the current location of the mobile terminal, and even if the mobile terminal changes the communication area, it must ensure the continuity of communic...
