Problems solved by technology

[0006] It is not difficult to see from the above two existing adjustment methods of bandwidth rate levels that the existing methods have the following deficiencies: the network side needs to design the adjusted rate level in advance according to the characteristics of each service, and it needs to be analyzed The rationality of each level rate and the number of levels requires a large workload; the level difference rate set by the existing bandwidth rate level is small when the rate is low, and the level difference rate is too large when the rate is high, so it cannot be well Adapt to certain rates required by the current business; the first method is easy to make the rate converge, but the adjustment process is slow and takes a long time, while the second method although the adjustment process is faster, it is difficult to achieve the rate Convergence, and if the traffic measurement is inaccurate, this method will fail; in the second method, the traffic measurement only represents the buffer occupancy status before the measurement report is reported, and does not represent the subsequent traffic measurement. Therefore, the This method of adjusting the bandwidth rate level has a certain degree of blindness, especially in the case of inaccurate measurement, the adjustment action of this method will not meet the actual bandwidth requirements; since PS services are generally transmitted using the TCP / IP protocol, sending The party will adjust the window size with the timely return of the acknowledgment (ACK) signal. If the access network does not provide the required bandwidth in time, the average transmission rate of TCP may decrease, causing the wireless access network to become a network transmission bottleneck. Affect the use of upper-level services, resulting in a decline in user satisfaction

Embodiment Construction

[0036] The method of the present invention will be further described in detail below in conjunction with the drawings and the embodiments of the present invention.

[0037] figure 1 It is a flowchart of the adjustment process of the wireless channel bandwidth in the embodiment of the present invention, such as figure 1 As shown, the adjustment process includes:

[0038] Step 101: Set environment variables, allocate initial bandwidth for mobile terminals on the side of the access network, and start the measurement of uplink and downlink channel traffic to generate a traffic measurement report.

[0039] Here, the setting environment variables include: setting the upper limit of user bandwidth maxLimit, the lower limit of user bandwidth minLimit; setting the maximum number of up steps maxUpNum, the maximum number of down steps maxDownNum; and setting three temporary variables: the target maximum value tmpMax for this adjustment, The adjusted target minimum value tmpMin this time, a...

Abstract

The invention discloses an adjusting method for wireless signal-path band width, which has the following steps: the upper limit value and the lower limit value of the band width of an up signal path and a down signal path of a mobile terminal, the maximum rising step frequency, the maximum lowering step frequency and three temporary variables are set; the maximum value of the band width of the former target, the minimum value of the band width of the former target, and the target value are adjusted; the band width of the prior wireless signal path is adjusted according to the measuring report of business volume; whether the adjusting direction of the band width of the current time and the adjusting direction of the band width of the last time is same is compared; the target band width value, the upper limit value of the band width of the current time and the lower limit value of the band width of the current time to be adjusted are respectively determined according to different conditions to carry out dynamic band width distribution. The method of the invention enables the air interface of the mobile communication system to timely response the change of the band width requirement of the business, rapidly raise or lower the band width, increase the utilizing rate of the band width of the mobile region, and improve the experience of the user.

Description

Technical field [0001] The present invention relates to the wireless channel bandwidth allocation technology of the third generation mobile communication (3G) system, and in particular to a method for adjusting the wireless channel bandwidth. Background technique [0002] The packet switching (PS) technology is introduced into the 3G communication system. Due to the many advantages of the PS technology itself, the communication services are diversified, and therefore it is more in line with the actual business needs of users. However, the diversification of communication services also brings new problems. Due to the different requirements of various services for wireless bandwidth, the radio access network (RAN) side of mobile communication has to face more complicated channel bandwidth allocation problems. Therefore, in order to solve the problem of reasonable bandwidth allocation, a radio bearer control (RBC, Radio Bearer Control) function is introduced to complete the channel ...
