- the responder's time stamps T2 and T3 may be used alternatively or in addition.
- the response time becomes relatively long, not only does the communication path between the wireless network control device and the mobile terminal increase, but also the processing time from reception to transmission at the mobile terminal becomes longer. It is also possible that it has become larger. If the responder's time stamps T2 and T3 are used, such a situation can be grasped.
- the wireless network control device transmits the received data to the mobile terminal (604).
- the timer in the retransmission means 410 starts in accordance with this transmission time.
- the mobile terminal that has received the signal from the network control device returns an ACK or NACK response signal to the signal (606). This reply signal reaches the radio network controller at time t2, and the timer is stopped and reset.
- the wireless network control device transmits the data to the mobile terminal again (not shown).
- the response time of the communication path being used is long: for example, there is a possibility that retransmission may be performed despite normal transmission and reception. Therefore, in response to the mobile terminal not responding within the predetermined period, at time t5, the wireless network control device transmits a time stamp request message (612). In response, the mobile terminal sends a timestamp response message, which is received at time t7.

- timeout time time
- FIG. 9 shows a timing chart of signal processing for each layer or node.
- this timing chart relates to the transmission and reception of signals described in 608 and 610 in FIG.
- the radio network controller receives a data from a node such as an exchange, and performs a predetermined length of, for example, 40 octets by a function in the RLC layer. Is divided into multiple data (here, four). According to the frame 'protocol (FP) of the radio network controller, the divided received data transmits each data to the base station (node) at regular intervals according to the contents of the TFS.
- FP frame 'protocol
- the data capacity specified by TFS is, for example, one packet of 40 octets.
- Data 1 to data 4 are transmitted in order at every interval Ts.
- the * on data 4 indicates that the polling 'bit is set.
- the mobile terminal that has received the data with the polling bit set returns an ACK or NACK response. ! / ,.
- Such a polling 'bit is generally set in the last data of the data divided by the RLC. Therefore, the mobile terminal does not return a response when receiving data 1 or 3, but returns a response when receiving data 4.
- the IP transmission path power S is included in the communication path between the wireless network control device and the base station, and the response time exceeds the timeout time.
- the radio network controller measures the response time using the time stamp request message and the time stamp response message, and sets a new TFS.
- the radio network controller receives data from the upper layer and divides it into, for example, four data by a function in the RLC layer. Up to this point, it is the same as the previous example (902).
- the received data divided is transmitted for each data amount (here, two packets each) defined by the TFS and at regular time intervals Ts. Since the polling 'bit is set in data 4, the mobile terminal that has received this returns an ACK or NACK response.
- Timing unlike what was described in Chart 902, since the two packets are transmitted from the FP, the time when the mobile terminal receives data 4 is also earlier, and as a result, the response time is shortened by Td. , Within the timeout period. Each node is notified that the content of the TFS has changed between times t6 and t7 (FIG. 6). In this way, it is possible to adjust the response time by appropriately changing the contents of the TFS.
- FIG. 10 shows a flowchart for updating the TFS and the transmission path bandwidth mainly performed in the radio network controller.
- the flow starts from step 1002.
- a time stamp request message is transmitted to the mobile terminal through the base station, and a time stamp response message is received from the mobile terminal.
- step 106 included in the received time stamp response message Using the time information, calculate the response time for the communication path.
- step 108 it is determined whether the response time is greater than a threshold. This threshold value is shorter than a predetermined period (timeout time) for retransmission.
- the flow ends without changing the value of TFS or the like until the response time is shorter than ⁇ 1 (1022). If the response time is too short, transmission efficiency may be degraded due to the long time until retransmission.Therefore, if the response time is shorter than a predetermined threshold, change the TFS or transmission band. Also ⁇ .
- step 11010 the response time is compared with the timeout period. If the response time is longer than the timeout period, the process proceeds to step 1102. Since it is difficult to respond within the timeout period, it is necessary to change the TFS to shorten the response time. How to change the contents of the TFS may be calculated by the TFS determining means 418 each time, or may be obtained by referring to a table such as a management template 422. good. On the other hand, if the response time is longer than the timeout, the process proceeds to step 114, where the data transmission rate is determined.
- FIG. 11 shows a flowchart for determining the transmission rate (set rate) in step 1014 of FIG.
- a maximum rate which is the maximum transmission rate that can be actually transmitted, is calculated or read from a table based on the transmission path bandwidth and response time.
- the maximum rate is compared with the set rate (the currently set transmission rate, which corresponds to the one described in the third column from the left in FIG. 5). If the maximum rate is not higher than the set rate, some of the actually set communication resources will be wasted, so the transmission (for calculation of the transmission path bandwidth) must be avoided.
- Set the rate to the maximum rate step 1 1 1 2). If the maximum rate is greater than the set rate, in step 1106 the maximum rate and the desired rate are compared.
- step 110 the transmission rate for calculating the transmission path bandwidth is set to the maximum rate.
- the desired rate is not higher than the maximum rate, it is possible to transmit as desired. Set the transmission rate for transmission path bandwidth calculation to the desired rate.
- an appropriate transmission path band is determined in step 11016. This makes it possible to allocate communication resources appropriately according to the actual situation of the communication environment in consideration of the response time.
- the contents of the management table 420 such as TFS, maximum rate, and set rate are updated to various values to be changed.
- this updated content is notified to each node, and the flow ends (1002).
- the control related to the change of the TFs and the transmission band according to the present invention is performed before calculating the response time in step 106. It is also meaningful to judge whether or not you have the ability to do so. For example, if the mobile terminal does not support the communication system according to the present invention, the time stamp request message cannot be properly interpreted and a parameter error message is returned. A mobile terminal that makes such a response can be excluded from control. Alternatively, the radio network controller can control the mobile terminal based on whether or not the control is desired.
- control flag in the time stamp response message
- determination based on the value of this control flag it is possible to set the control according to the present invention to be performed at a predetermined time or periodically. It is also possible to measure response time when the number of connections in the system is less than a predetermined number.
- the radio network controller transmits the required data to the base station by dividing the data into a predetermined data size, and the communication path used by the mobile terminal. And measuring the response time of the signal in step (a), and changing the predetermined data size based on the response time.
- transmission efficiency can be improved.
- the data transmission amount (TFS) can be appropriately controlled by the frame 'protocol (FP) located in the lower layer of the radio network layer (RNL), the frame' protocol (FP) There is no need to change the control contents in the upper layer. In other words, managed by upper layer RLC It is possible to improve transmission efficiency without changing the time-out time for retransmission performed.
- the communication resources in the wireless link are also managed based on the measured response time. As a result, it is possible to efficiently use the communication resources secured by the communication link without any excess or shortage.
- the radio network controller receives the time stamp request signal from the mobile terminal, and the radio network controller receives the time stamp response signal from the mobile terminal. Can be easily measured. By transmitting a time stamp request signal when the time exceeds the timeout period, measuring the response time, and adjusting the data transmission unit (TFS), it becomes possible to quickly cope with the fluctuation of the communication environment. If the response time is measured in a timely manner, since the data transmission unit is adjusted, the probability that the timeout period expires can be reduced. It is also possible to do it when ⁇ reaches the time specified in advance.
- the base station transmits a time negotiation message (time adjustment signal) to the wireless network controller, and the base station transmits It is also possible to adopt a point in time when data transmission / reception between wireless network control devices is adjusted. This can be performed when the number of mobile terminals with which the base station is communicating becomes smaller than a predetermined number.
