PROBLEM TO BE SOLVED: To provide a communication terminal, a server device, a movement guide system, and a computer program that can shorten a time necessary for the communication terminal to obtain guide information necessary for movement guide of a mobile body from the server device when center route search is performed.SOLUTION: A communication terminal 5 has an update area table 49 distinguishing a section corresponding to update object area where terminal side map information 48 held by the communication terminal 5 is map information based on an older version than device side map information held by a server device from a section not corresponding to the update object area by the section unit of the map information. The communication terminal requests the server device to transmit movement guide information 26 for performing movement guide to a mobile body on the basis of the update area table 49.SELECTED DRAWING: Figure 3

    【課題】センタールート探索を行う際において、通信端末が移動体の移動案内を行うのに必要な案内情報をサーバ装置から取得するまでに必要な時間を短縮化することを可能にした通信端末、サーバ装置、移動案内システム及びコンピュータプログラムを提供する。【解決手段】地図情報の区画単位毎に、サーバ装置が有する装置側地図情報に対して通信端末5が有する端末側地図情報48が古いバージョンの地図情報となる更新対象エリアに該当する区画と、更新対象エリアに該当しない区画と、を識別した更新エリアテーブル49を通信端末5が有する。更新エリアテーブル49に基づいて移動体の移動案内を行う為の移動案内情報26をサーバ装置に要求する。【選択図】図3
