Description

(実施の形態1)
本発明の実施の形態1に係る位置管理サーバについて、図面を参照しながら説明する。
図1は、本実施の形態による位置管理システムの構成を示す図である。図1において、本実施の形態による位置管理システムは、有線または無線の通信回線100を介して互いに接続された、位置管理サーバ1と、2以上の端末装置2とを備える。位置管理サーバ1は、2以上の端末装置2の位置を管理する。端末装置2は、例えば、携帯電話や、PC(Personal Computer)、PDA(Personal Digital Assistant)などであり、ユーザが持ち運ぶことができるものである。また、これらの端末装置は、GPS対応機能を有している。通信回線100は、例えば、インターネットやイントラネット、公衆電話回線網等である。
(Embodiment 1)
A location management server according to Embodiment 1 of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a location management system according to the present embodiment. In FIG. 1, the location management system according to the present embodiment includes a location management server 1 and two or more terminal devices 2 connected to each other via a wired or wireless communication line 100. The position management server 1 manages the positions of two or more terminal devices 2. The terminal device 2 is, for example, a mobile phone, a PC (Personal Computer), a PDA (Personal Digital Assistant), and the like that can be carried by the user. Moreover, these terminal devices 2 have a GPS compatible function. The communication line 100 is, for example, the Internet, an intranet, a public telephone line network, or the like.

端末位置情報は、端末識別情報で識別される端末装置2の位置を示す情報である。端末位置情報は、例えば、経度と緯度を示す情報である。その端末位置情報は、例えば、GPS対応型の端末装置を用いて取得する。GPS対応型の端末装置を用いれば、位置情報を容易に時系列に蓄積することができる。端末装置2には、各取得時間における経度と緯度を示す情報が蓄積されている。これらの時系列の位置情報の中から、近接情報を得たいと望む、所定の期間または場所などを特定して、時系列の位置情報を端末位置情報とする。 The terminal position information is information indicating the position of the terminal device 2 identified by the terminal identification information. The terminal position information is information indicating longitude and latitude, for example. The terminal position information is acquired using, for example, a GPS-compatible terminal device 2 . If the GPS-compatible terminal device 2 is used, position information can be easily accumulated in time series. The terminal device 2 stores information indicating longitude and latitude at each acquisition time. From these time-series position information, a predetermined period or place where the user wants to obtain proximity information is specified, and the time-series position information is used as terminal position information.

近接状態検出部14は、位置管理情報記録部13が記憶している位置管理情報を用いて、受信部11が受け付けたの端末装置2との近接状態を検出する。ここで、近接状態とは、同時刻に一の端末装置2と他の端末装置2とが一定の範囲内に存在する状態である。近接状態が検出されることによって、一の端末装置2と他の端末装置2とが近くに存在する(いわゆる、すれ違い状態になっている)ことが検出される。また、一定の範囲とは、近接情報を求めるユーザが一定の範囲と認識する範囲である。 The proximity state detection unit 14 detects the proximity state with the one terminal device 2 received by the reception unit 11 using the location management information stored in the location management information recording unit 13. Here, the proximity state is a state in which one terminal device 2 and another terminal device 2 exist within a certain range at the same time. By detecting the proximity state, it is detected that one terminal device 2 and another terminal device 2 exist in the vicinity (a so-called passing state). In addition, the certain range is a range that is recognized as a certain range by a user who seeks proximity information.

(ステップS104)
近接状態検出部14が近接状態を検出した場合には、送信部15は、近接状態検出部14が検出した近接状態に対応する端末装置2送信して、近接状態の検出を終了する。
(Step S104)
If the neighboring state detector 14 detects the proximity state, the transmitting unit 15, proximity detector 14 is transmitted to the terminal device 2 corresponding to the proximity state detected, and terminates the detection of the proximity state.

距離算出手段21は、一の端末装置2の端末位置情報と、位置管理情報記録部13から読み出した他の端末装置2の端末位置情報とを用い、両者の端末位置情報から、両者の端末装置2間の距離を算出する。位置を示す情報から距離を算出する方法はすでに知られているため、その詳細な説明を省略する。一の端末装置2と他の端末装置2との間の距離が1.8メートルであった場合には、比較手段22は、その算出された距離と、閾値メートルとを比較し、2個の端末装置2間の距離が閾値以内であると判断する(ステップS103)。比較手段22は、閾値以内であった、他の端末装置2の情報を図示しない記録媒体で一時的に記録する。上記位置管理情報記録部13に記録されている、特定の時刻における位置情報の場合は、この操作で、他の端末装置2の情報とする。また、一の端末装置2が所定の時間内で移動した場合には、この時間内における移動の軌跡上で近接した他の端末装置2の距離をそれぞれ算出する。時系列に蓄積された位置管理情報に基づいて近接状態にある他の端末装置2を検出する場合は、一の端末装置2と他の端末装置2のそれぞれの軌跡を例えば二次元座標に配置し、両者か近接した、あるいは交わった部分について、上記のように距離を算出する。次に、上記他の端末装置2以外の他の端末装置2についても、順に一の端末装置2との間の距離を算出して、比較する。最終的に、閾値以内にある他の端末装置2の情報のリストを作製する。 The distance calculation means 21 uses the terminal position information of one terminal apparatus 2 and the terminal position information of the other terminal apparatus 2 read from the position management information recording unit 13, and based on both terminal position information, both terminal apparatuses The distance between the two is calculated. Since the method for calculating the distance from the information indicating the position is already known, detailed description thereof is omitted. When the distance between one terminal device 2 and another terminal device 2 is 1.8 meters, the comparison unit 22 compares the calculated distance with a threshold value of 2 meters, It is determined that the distance between the terminal devices 2 is within the threshold (step S103). The comparison unit 22 temporarily records the information of the other terminal device 2 that is within the threshold using a recording medium (not shown). In the case of position information at a specific time recorded in the position management information recording unit 13, it is set as information of another terminal device 2 by this operation. Further, when one terminal device 2 moves within a predetermined time, the distances of other terminal devices 2 that are close to each other on the locus of movement within this time are calculated. When detecting another terminal device 2 in the proximity state based on the position management information accumulated in time series, the trajectories of one terminal device 2 and the other terminal device 2 are arranged in, for example, two-dimensional coordinates. Then, the distance is calculated as described above for the parts that are close to or intersect with each other. Next, with respect to the other terminal devices 2 other than the other terminal devices 2 as well, the distance from the one terminal device 2 is calculated and compared in order. Finally, a list of information of other terminal devices 2 within the threshold is created.

近接状態検出部14は、所定の位置と、端末装置との近接状態を検出する。ここで、近接状態とは、所定の位置と端末装置とが一定の範囲内に存在する状態である。この検出方法は、実施形態1と同様である。 The proximity state detection unit 14 detects a proximity state between the predetermined position and the terminal device 2 . Here, the proximity state is a state where the predetermined position and the terminal device exist within a certain range. This detection method is the same as in the first embodiment.
