Problems solved by technology
If the two areas are located on the same ring, it is obvious that the bandwidth requirements of the two areas are complementary. At this time, if a fixed guaranteed rate is configured, there will be a waste of resources
In some cases, it cannot be guaranteed at the same time, and the guaranteed rate can only be reduced at the same time, which will affect the peak throughput, such as image 3 As shown, if the two eNBs belong to the same PTN ring, and the total bandwidth cannot exceed 120Mbps, they can only be configured to 60Mbps at the same time, and data will be discarded if the part exceeds it.
This method of fixed configuration to ensure bandwidth will cause waste of PTN transmission resources and affect the peak throughput of the wireless network

Embodiment Construction
[0027] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings:
[0028] The system composition structure diagram of the present invention is as figure 1 As shown, the present invention is divided into three subsystems: wireless access network network management subsystem, PTN network management subsystem, and data center. The composition of each subsystem is as follows:
[0029] Radio access network management subsystem: The system mainly borrows the existing LTE radio access network management network to provide, including enhanced base station eNB (EvolvedNodeB), wireless operation and maintenance center OMC-R (Operations and Maintenance Centre-Radio), access network Network management center.
[0030] PTN network management subsystem: The system uses the original PTN network management network, including PTN network management and PTN equipment.
[0031] Data Center: This subsystem is a newly added s...

The invention discloses a PTN transmission bandwidth adaptive adjustment method based on data mining. According to the method, the PTN transmission bandwidth is dynamically adjusted; through data mining conducted on the eNB actual transmission bandwidth, the law of the eNB actual transmission bandwidth changing along with time is found; wireless access network webmaster PM data are used as an input source for PTN transmission bandwidth analysis; with the combination of information such as the eNB priority and an eNB actual transmission bandwidth data mining result, transmission bandwidth configuration of the eNB is determined. According to the technical scheme, dynamic configuration of the bandwidth can be achieved according to the actual transmission bandwidth changing law of the eNB, so that PTN transmission resources are effectively used, and under the condition that the transmission resources are limited, the throughput capacity of the eNB can be better improved.
Description
Technical field [0001] The invention discloses a PTN (Packet Transport Network) transmission bandwidth adaptive adjustment method based on data mining, and relates to the technical field of data processing. Background technique [0002] With the gradual maturity of 4GLTE (LongTerm Evolution) technology, its actual networking applications have also been gradually promoted. As the current peak rate that can be carried by LTE networks has reached 100M, compared to traditional 3G technology, it greatly improves user experience while , It also brings huge pressure on the backhaul network. Take a small city as an example. If it builds 500 base stations with 1500 carrier fans, the average transmission bandwidth (CIR) of each carrier sector (CIR) is 100Mbps, the peak transmission bandwidth (PIR) is 300Mbps, and 10 nodes are connected to each access ring. With 10 nodes connected to each aggregation ring and 5 nodes on the core ring, the peak crossover capacity on the access ring will rea...
