Problems solved by technology

[0009] Since the existing mobile communication system is configured as described above, it is possible to realize asymmetric wireless communication in which the transmission speeds of the uplink 4 and the downlink 8 are different, but since there is no device for changing the transmission speed of communication data, , once the transmission speed of communication data is set, there is a problem that it cannot be changed to a transmission speed suitable for the data volume even if the data volume changes over time in the future

Abstract

A mobile exchange station changes a transmission speed of communication data from a mobile station, etc. to database or from the database to the mobile station, etc. individually, in response to the request from the mobile station, etc. or the database.

Description

[0001] This application is a divisional application of the parent application with the application number 200310116111.0 and the filing date on December 10, 1997. The previous international application of the parent application is PCT / JP9704551, and the international filing date is December 10, 1997. technical field [0002] The present invention relates to a mobile communication system in which an asymmetrical data communication channel is set in which the transmission rate of communication data transmitted from a mobile station to a base station is different from the transmission rate of communication data transmitted from a base station to a mobile station. Background technique [0003] figure 1 It is a configuration diagram showing a conventional mobile communication system disclosed in, for example, JP-A-8-331153. In the figure, 1 is a movable mobile station installed in a car, etc., 2 is a low-speed transmission device that transmits communication data at a low transmi...
