- the reference position information is not set in the cell.
- the location information storage / save unit 65 stores the location information by historically storing it, but for each cell, the average value of the location information and the average value thereof are stored. Only the number of location information used to calculate the value may be stored and stored.
- the position information is stored before the correction determination process 110 is performed. However, the position information is stored after the correction determination process 110 is performed. It's fine.
- the position calculation is not performed by itself.
- MS-Assisted method the mobile communication terminal device force assist information to be positioned is requested and the positioning is performed.
- location information from a terminal other than the mobile communication terminal that is the target of positioning and request positioning (MT-LR).
- the positioning result of assist GPS positioning is applied to the reference position information correction determination and the reference position information correction as the position information of the mobile communication terminal device.
- the information may be applied to the reference position information correction determination and the reference position information correction.
- the assist server is the same device as the server device that is the server system of the present invention, but may be a different server device!
- the server device 50 as the server system of the present invention may be a server system constituted by a plurality of server devices that are assumed to be a single server device.
- the mobile communication terminal device is applied as a mobile phone, but it is needless to say that the present invention can be applied to mobile communication terminal devices other than mobile phones.
- the reference position information correction method of the present invention can be applied to a server device that manages cell position information.
- the server system of the present invention can be applied to a server system that manages cell location information.
- the reference position information correction system of the present invention can be applied to a mobile communication system including a server device that manages cell position information.
