Transmission rate switching in a mobile communication system
View Patent ↗In a mobile communication system, a mobile switching center 27 changes a transmission rate of communication data transmitted from a mobile station 16 and so on to a database 11 or a transmission rate of communication data transmitted from the data 11 to the mobile station 16 and so on, on a basis of request from the mobile station 16 and so on or the database 11 , individually and independently.
1. A communication control system for controlling radio communication performed by a radio communication system, comprising:
a transmission rate notifying section for notifying the radio communication system of a transmission rate for radio communication performed by the radio communication system; and
a timing notifying section for notifying to the radio communication system of a rate switching time at which the transmission rate in the radio communication system would be switched to the transmission rate notified by the transmission rate notifying section.
2. The communication control system according to claim 1 , wherein the radio communication system is a base station for performing radio communication to mobile stations in a radio covered area.
3. The communication control system according to claim 1 , wherein the radio communication system is a mobile station, belonging to a radio covered area of a base station, for performing radio communication to the base station.
4. A radio communication system for performing radio communication based on information transmitted from a communication control system, comprising:
a transmission rate receiving section for receiving transmission rate information transmitted from the communication control system; and
a timing receiving section for receiving a rate switching time at which a transmission rate in the radio communication system would be switched to the transmission rate represented by the transmission rate information received by the transmission rate receiving section.
5. The radio communication system according to claim 4 , wherein the radio communication system is a base station for performing radio communication to mobile stations in a radio covered area.
6. The radio communication system according to claim 4 , wherein the radio communication system is a mobile station, belonging to a radio covered area of a base station, for performing radio communication to the base station.
7. A communication control method of controlling radio communication performed by a radio communication system, comprising the steps of:
transmitting to the radio communication system a notification of a transmission rate for radio communication performed by the radio communication system; and
transmitting to the radio communication system a notification of a rate switching time at which a transmission rate in the radio communication system would be switched to the transmission rate notified.
