Problems solved by technology
Among them, single-step upward adjustment means that the transmission rate of the air interface is configured into several levels in advance. When the traffic measurement report requires an increase in channel bandwidth resources, the rate is increased step by step according to the pre-configured rate level. The method is characterized by upward adjustment If the speed is too slow, it often lags behind the actual needs of the business, and the user experience is poor; and the method of directly increasing the maximum rate of the service contract, although the user experience is good, but the precious wireless resources may not be used reasonably. The problem of wasting wireless resources

Embodiment Construction
[0031] Below in conjunction with accompanying drawing, concrete implementation of the present invention is described in further detail:
[0032] The method for upward dynamic adjustment of the wireless access rate of the packet service in the system of the present invention is as follows: figure 2 and image 3 shown, including the following steps:
[0033] Step 201, the system configures the transmission interval TTI and the minimum upward adjustment threshold value A in the background database in advance0 , Coefficient C th , delay time TimeTriggerA of traffic reporting event, shielding time PendingTimeA, configurable rate set and other parameters;
[0034] Among them, the TFS corresponding to all rates is TFS={TF 1 , TF 2 ,...,TF n}, where TF n The transport format (TF) with the largest sum of transport block sizes in the set. Each transport format TF in the set i =TBNum i × TBSize. Among them, TBNum is the number of transmission blocks, and TBSize is the size of...

The invention discloses a method for dynamically upward regulating the wireless access rate of packet services. The method includes the following steps of according to a transport format set (TFS) corThe invention discloses a method for dynamically upward regulating the wireless access rate of packet services. The method includes the following steps of according to a transport format set (TFS) corresponding to the current rate, calculating the current upward-regulation threshold; sending a measurement control message from a network side to a user side or from a network side to a network side;responding to the current rate, calculating the current upward-regulation threshold; sending a measurement control message from a network side to a user side or from a network side to a network side;when traffic volume exceeds the current upward-regulation threshold, sending a traffic volume measurement report carrying the newest report volume from the user side to the network side or from the newhen traffic volume exceeds the current upward-regulation threshold, sending a traffic volume measurement report carrying the newest report volume from the user side to the network side or from the network side to the network side, and then determining a candidate rate and further determining a target rate according to the newest report volume as well as the state of a timer started in a previoustwork side to the network side, and then determining a candidate rate and further determining a target rate according to the newest report volume as well as the state of a timer started in a previousreport event; and after the target rate is determined to be not equal to the current rate, regulating the target rate to the newest current rate and re-configurating the TFS of the packet service accoreport event; and after the target rate is determined to be not equal to the current rate, regulating the target rate to the newest current rate and re-configurating the TFS of the packet service according to the target rate. By the use of the method, the air interface rate of the service can be rapidly and accurately improved when burst packet arrives, thus improving the performance of wireless nrding to the target rate. By the use of the method, the air interface rate of the service can be rapidly and accurately improved when burst packet arrives, thus improving the performance of wireless network and the sense of experience of a user.etwork and the sense of experience of a user.
Description
technical field [0001] The invention relates to a wireless access rate adjustment technology, in particular to a method for dynamically adjusting upwards the wireless access rate of a packet service. Background technique [0002] With the development of the third-generation mobile communication technology, it has become an operation business urgent needs. The biggest transmission characteristic of the data grouping business is the suddenness and the dynamic change range of the rate. For the data packet service, if a fixed channel bandwidth resource is allocated for it, it may not be able to meet the demand for fast data transmission when the data bursts, and it will cause a waste of channel bandwidth resources when the amount of data is small. In order to improve the utilization efficiency of wireless channel resources, the communication system should be able to dynamically configure the allocated channel bandwidth resources according to the business volume requirements of...
