HISTORY OF THE INVENTION

1. FIELD OF THE INVENTION

The present invention relates to a method of controlling the speed of transmission to control the speed of data transmission of the user on the uplink, a mobile station, and a base radio station. RELATED TECHNOLOGY DESCRIPTION

In a conventional mobile communication system, on an uplink from an EU mobile station to a Node B base station, an RNC radio network controller is configured to determine the transmission speed of a dedicated channel, taking into account the resources base station radio frequency of Node B, a volume of interference on an uplink, the transmission energy of the mobile station UE, the transmission processing performance of the mobile station UE, a transmission speed required for a higher application, or similar, and notify the determined transmission speed of the dedicated channel by a layer 3 message (Radio Resource Control Layer) for both the EU mobile station and the Node B base station.

Here, the RNC radio network controller is provided at a higher level than the Node B base station, and is a

2/33 • «« «• · · · · * · · ♦ t •« · * · • · · »· • ¹⁰

apparatus configured to control the base station of Node B and the mobile station UE.

In general, data communication often causes bursty traffic compared to voice communication or TV communication. Therefore, it is preferable that the transmission speed of a channel used for data communication be changed quickly.

However, as shown in Figure 1, the RNC radio network controller fully controls a plurality of Node B base stations in general. Therefore, in the conventional mobile communication system, there was a problem that it is difficult to perform quick control for changing the transmission speed of the channel (for example, by approximately 1 to 100 ms), due to the processing load, processing delay, or similar.

In addition, on the conventional RNC radio network controller, there was also the problem that the costs to implement an apparatus and to operate a network are substantially increased even if rapid control for changing the channel's transmission speed can be carried out.

Therefore, in the conventional mobile communication system, the control for changing the transmission speed of the channel is generally carried out in the order of a few hundred ms to a few seconds.

Thus, in the conventional mobile communication system, when burst data transmission is performed as shown in Figure 2A, the data is transmitted by accepting low speed, high delay, and low transmission efficiency as shown in Figure 2B or, how is it * · "· · * * * · · · · · · ·, • * · * * · · · " · · " ·. «♦ · ··» · · • * * ·· ·· ·· • · ·· ·· · »·· ·

3/33 shown in Figure 2C, when reserving radio resources for high-speed communication to accept that radio bandwidth resources in an unoccupied state and hardware resources on the Node B base station are wasted.

It should be noted that both the radio bandwidth resources and the hardware resources described above are applied to the vertical radio resources in the Figures

2B and 2C.

Therefore, the Third Generation Partnership Project (3GPP) and the Third Generation Partnership Project 2 (3GPP2), which are organizations of international standardization of the third generation mobile communication system, discussed a method to control high radio resources speed in a layer 1 and sub-layer of media access control (MAC) (a layer 2) between the base station Node B and the mobile station UE, in order to effectively use the radio resources. These discussions or functions discussed will hereinafter be referred to as

Enhanced Ascendant (EUL).

In the Enhanced Uplink, a MAC-layer function, which is located in each cell of a Node B base station, is configured to control the data transmission speed of the uplink user transmitted by a mobile station UE, using two transmit speed control channels described below.

As a first method of transmitting speed control, the MAC-layer function located in each cell of the Node B base station is configured to transmit <♦ * • <

V an absolute value for a maximum allowed transmission speed of uplink user data (or parameter related to the maximum permitted transmission speed) for each mobile station UE (individual mobile stations or all mobile stations) using a Concession Channel. Absolute Speed (AGCH), in order to control the data transmission speed of the

user of uplink of each EU mobile station. On here, O parameter described above related to velocity in streaming allowed maximum is a proportion power in streaming between one Channel Physical Data

Enhanced Dedicated (E-DPDCH) ”and a Dedicated Physical Control Channel (DPCCH) (hereinafter, a proportion of EDCH transmission energy) or similar. This proportion of EDCH transmission energy is calculated by the transmission energy of the E-DPDCH / transmission energy of the DPCCH.

The increase / decrease in the parameter related to the maximum allowed transmission speed corresponds to the increase / decrease in the transmission speed, and is acquired in connection with the transmission speed. In 3GPP, this parameter related to the maximum allowed transmission speed is defined as the proportion of EDCH transmission energy (See, unpatented literature 1: 3GPP TSG-RAN TS25.309 v6 1.0).

As a second transmission speed control method, the MAC-layer function located in each cell of the Node B base station is configured to transmit a command indicating relative values such as an Up Command, a Down Command, a Keep Command , or similar, for a permitted transmission speed

When the mobile station UE transmits user data on the uplink, the proportion of EDCH transmission energy that can be accepted by the mobile station UE (maximum allowed EDCH transmission energy proportion of the mobile station UE) is determined using the control channels of mentioned above (AGCH and RGCH).

Then, the mobile station UE determines a transmission data block size (TBS: Transport Block Size) per transmission time interval (TTI: Transmission Time Interval), based on the size of the user data on the link upstream stored in a transmission buffer and the maximum allowed EDCH transmission power ratio of the mobile station UE.

Here, the mobile station UE is configured to determine the transmission data block (TBS) size by transmission time interval (TTI) using a matching table showing the correspondence between a transmission data block size (TBS) ) and the EDCH transmission power ratio of the user data on the uplink.

As shown in the non-patented literature 2 (3GPP TSG - RAN R2- 042717), the RNC radio network controller is configured to notify the correspondence table for

6/33 the mobile station UE by a layer-3 signaling, when the call establishment is made.

Furthermore, as shown in the non-patented literature 2, ♦

the RNC radio network controller is configured to - 5 notify the matching table that shows the match between the block size of the data. transmission (TBS) and a transmission wave amplitude ratio between an Enhanced Dedicated Physical Data Channel (E-DPDCH) and a dedicated Physical Control Channel 10 (DPCCH) (hereinafter, an EDCH transmission wave amplitude ratio) , for the Node B base station and the EU mobile station. This proportion in the amplitude of the EDCH transmission wave is calculated by the amplitude of the transmission wave of the E-DPDCH / amplitude of the transmission wave of the

DPCCH.

As mentioned above, in the conventional mobile communication system that uses Enhanced Uplink, the RNC radio network controller is configured to notify both the table of correspondence between the transmission data block size (TBS) and the energy rate EDCH transmitters and the corresponding table between the transmit data block size (TBS) and the transmit wave amplitude radio, for the Node B base station and the EU mobile station, using layer-3 signaling .

Thus, there was a problem that the amount of Layer-3 signaling becomes enormous, and the delay for the call connection occurs.

As shown in Figure 14A, in step S101, the mobile station UE receives control information related to layer 2 from the RNC radio network controller.

Then, the mobile station UE extracts the first correspondence table of the transmission data block size and the amplitude ratio of the EDCH transmission wave (see Figure 6), of the control information related to the received layer 2, in order to extract the first match table.

In step S102, the mobile station UE generates the second correspondence table (second correspondence) of the transmission data block size and the EDCH transmission energy ratio, based on the first correspondence, in order to generate the second correspondence table .
