The invention relates to a system and a method with which a real-time map is capable of being displayed and shared in a mobile terminal, and particularly relates to a system and a method with which real-time geographical location information is mutually shared, wherein the system and the method with which the real-time geographical location information is mutually shared are embedded in a mobile terminal. The system and the method with which the real-time geographical location information is mutually shared have the advantages that the system and the method with which the real-time map is capable of being displayed and shared in the mobile terminal are provided, and real-time geographical location information share can be achieved among a plurality of users. The system and the method with which the real-time map is capable of being displayed and shared in the mobile terminal comprise a service terminal and at least one mobile intelligent terminal , wherein the service terminal is connected with the mobile intelligent terminal through a network, the service terminal comprises a transceiver module, a map module and a cutting module, and the mobile intelligent terminal comprises a global position system (GPS) positioning module, a map control module, a map display module and a transceiver module. According to the system and the method with which the real-time map is capable of being displayed and shared in the mobile terminal, the vector map of location can be displayed in the customer mobile intelligent terminal, the vector map of location can be shared with sharers, and the system and the method with which the real-time map is capable of being displayed and shared in the mobile terminal are not affected by phone models and functions as long as the mobile phone has GPS function.
