Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 4, and fig. 5 (a) and 5 (B) in the embodiments of the present invention.
Fig. 1 is a flowchart of one embodiment of a method for speed reduction of a target volume based on PCF of internet of things according to the present invention. As shown in fig. 1, the method of this embodiment includes:
s1, dividing the speed into a plurality of intervals;
s2, dividing gears in a plurality of intervals, and dividing different speeds into different gears according to requirements;
s3, configuring reaching-quantity speed-down strategy data on the PCF, wherein the reaching-quantity speed-down strategy data comprises a public data set and a private data set; the common data set includes data of a repetitive function; the special data set comprises data needing to be configured independently;

s6, the PCF determines a gear of rate control according to the state value of the subscription strategy;
s7, issuing uplink and downlink strategy control to AMF;
s8, the AMF performs policy control on the internet of things card.
The speed is divided into a plurality of intervals, and different speeds in the divided intervals are divided into different gears, so that the speed limiting speed can be directly referenced through the gears when the speed limiting speed is used, and the speed control requirement of 4G/5G is met.
Meanwhile, only one policy needs to be configured on the PCRF/PCF, and on the configuration of the policy, public and special data configuration mode configuration data is adopted, wherein a public configuration part comprises data of a repetitive function, such as fixed data of 4G/5G conditions, 4G/5G condition groups, 4G/5G action groups, 4G/5G rules, 4G/5G rule groups and the like; the special configuration part comprises data needing to be configured independently, such as data needing to be changed, such as 4G/5G business, 4G/5G strategy rule and the like. Policy data is divided into a fixed public configuration section and a modified private configuration section. The data updating in the later stage only needs to add the gear data of a new special configuration part on the basis of a public configuration part, and the public configuration part is directly referenced to the public parameters needed by the policy gear, so that the occupation of policy permission is greatly reduced, the public configuration part is used as a library, the data of the library is basically fixed, the public configuration part only needs to be configured once, the subsequent data updating is added or modified on the change data, and the hidden danger of the change triggering of the data is reduced.
The invention manages the data set without great variation basically, greatly reduces risks caused by manual operation and cutting and updating, and directly refers to the parameters such as policy rules, business and the like of the follow-up policy to the rule names in the set.
As shown in table 1 and fig. 4, the present invention splits the down policy data into public and private from 6 months, and after the newly added up-to-date down policy references the public part data, it can be seen that the current network license utilization rate is significantly slowed down.
Table 1.5G action group quantity statistics table
Month of month | 1 month | 2 months of | 3 months of | 4 months of | 5 months of | 6 months of | 7 months of | 8 months of |
5G action group (strip) | 6230 | 7003 | 7847 | 8297 | 9018 | 9795 | 9946 | 10045 |
In a preferred embodiment, the method of the partition in S1 is partitioning according to a demand rate, specifically:
a first interval: 0Kbps; the user is forbidden to surf the internet;
the second interval: a rate of 1Mbps or less;
third interval: 1Mbps to 10Mbps;
fourth interval: 10Mbps to 100Mbps;
fifth interval: 100Mbps to 1Gbps.
By using the interval dividing method, the current common demand rate can be divided into 5 intervals according to different rate intervals, the rate contained in each interval is different, and different intervals can be selected according to the demand when in use.
In a preferred embodiment, the speed intervals divided according to the method can be divided into gears in different intervals according to the requirements of industry and the common speed control.
The specific gear dividing method in S2 is as follows:
a first interval: the gear positions are not divided up,
the second interval: the gear is divided into 10 gears, the gear is 1 to 10, one gear is added every 100kbps,
third interval: 10 gears, 11-20 gears, one gear is added every 1Mbps,
fourth interval: 20 gears, 21-40 gears, one gear is added every 5Mbps,
fifth interval: the gear is divided into 10 gears, and one gear is added to each 100Mbps of the gears 41-50.
That is, the range of the rate in each section is divided into ten parts, one gear is added every time one part is added, kbps needs to be subdivided because of more gears which need to be classified under 1M, one gear is added every 100Kbps, and the rate above 1M can be classified according to Mbps.
In a preferred embodiment, in consideration of the fact that the QCI is specific to the user, in the special case of congestion and the like, priority access is performed to the specific user preferentially, the QCI can be divided into three gears of QCI9, QCI8 and QCI6, the QCI9 is accelerated at a default rate, the QCI8 is the fluent acceleration for the crowd providing the acceleration service, and the QCI6 is the extremely fast acceleration provided by the special case emergency and the special user.
The QCI is subjected to gear division, so that when special conditions such as congestion occur, users signing the requirements of the useful network can access the network preferentially.
Further, the gear is named as a 6-bit number, the first bit is 1 or 2, the value 1 represents the gear with the speed controlled below 1M, and the value 2 represents the gear with the speed controlled between 1Mbps and 1 Gbps; the second bit is the QCI requirement, e.g., 9, 8 or 6; the third bit is whether the month is reset or not, the month is reset automatically when the value is 1, and the month is not reset automatically when the value is 2; the last three bits are shorthand for the speed value, specifically as follows:
1. if the speed limit is below 1M, i.e. the first digit of the gear name is 1, then the last three digits are named according to the speed, e.g. table 2,
TABLE 2 Gear naming schematic Table with speed limit below 1M
2. If the speed limit is between 1Mbps and 1Gbps, namely the second position of the gear name is 2, the naming rule of the last three positions of the gear is shown in table 3.
TABLE 3 Gear naming schematic Table for speed limit between 1Mbps and 1Gbps
Gear value | Uplink rate | Downlink rate | Gear value | Uplink rate | Downlink rate |
2XX001 | 1Mbps | 1Mbps | 2XX050 | 50Mbps | 50Mbps |
2XX002 | 2Mbps | 2Mbps | 2XX100 | 100Mbps | 100Mbps |
2XX005 | 5Mbps | 5Mbps | 2XX200 | 200Mbps | 200Mbps |
2XX008 | 8Mbps | 8Mbps | 2XX500 | 500Mbps | 500Mbps |
2XX010 | 10Mbps | 10Mbps | 2XX600 | 600Mbps | 600Mbps |
2XX020 | 20Mbps | 20Mbps | 2XX800 | 800Mbps | 800Mbps |
Specifically, when the gear speed limit is 1Gbps, the gear value is 2XX000.
In a preferred embodiment, for use convenience, the QCI gear and the rate requirement gear can be freely combined, for example, the user wants to turn on the internet of things card, but for special reasons, wants to control the rate at 5M common QOS, only the user needs to sign up for the rate control policy, the interval selects the second interval, the gear selects 15, that is, the up/down speed 5mbps, qci=9, that is, the default rate accelerates, the user can directly issue to the PCF through the N7 port according to the values of the gear and the QCI, and the PCF directly performs the rate limiting process on the user's card according to the gear bit rate predetermined by the policy, without going through the SMF (Session Management Function ).
In a preferred embodiment, the method for configuring the public data in S3 is:
s311, configuring a strategy condition group, wherein the strategy condition group is a combination of a plurality of conditions and comprises the names of the condition groups, the relation and description among all the conditions in the condition groups and other parameters;

The data of the 4G/5G condition, the 4G/5G condition group, the 4G/5G action group, the 4G/5G rule and the 4G/5G rule group are used as fixed parameters for management, and the data can be commonly referred by different strategies, so that the repeated configuration of the data of the current network is greatly reduced.
In a preferred embodiment, the method for configuring the dedicated data in S3 is as follows:
s321, configuring strategy basic information: the policy basic information comprises a policy, a quota and a roaming area;
s322, configuration strategy: the policy is a combination of a plurality of triggers and rules, and comprises parameters such as the name of the policy, the type of the policy, descriptive information of the policy and the like.
The 4G/5G service, the 4G/5G strategy and the 4G/5G strategy rules are used as change data, the subsequent capacity expansion can be added according to the characteristics of the strategy, and the rules with fixed parameters are directly referenced after the subsequent capacity expansion is added. The resources of the existing network are greatly saved, and the strategy data is tidier and more objective.
Further, the method for determining the number and the deceleration control strategy by the PCF in S5 is as follows:
s51, judging whether the number is registered, if so, performing the next step, and if not, not performing rate control on the number;
s52, judging whether the number has a signed deceleration strategy, if so, carrying out S5, and if not, not carrying out rate control on the number.

s62, searching corresponding rates on the public data according to the strategy of the private data, if yes, carrying out S7, and if not, not carrying out rate control on the numbers.
The following are tests of the invention:
test one:
and configuring an arrival deceleration strategy on the PCF in advance, completing configuration of gears and the data network, and testing the strategy signed by the Internet of things card. When no policy is signed, the rate of test number delivery is controlled to 100Mbps. The reason is that under the condition that the 4G/5G network exists, the PCRF/PCF does not limit the number, but the number is set according to the PGW (PDN GateWay) request rate, as shown in fig. 5 (A), the rate of the test number is issued to the PCRF/PCF through GX/N7 according to the PGW, the maximum uploading rate and the maximum downloading rate of the PGW application CCA (credit control request) are 100000000bps according to the signaling requirement of the PGW, and after the PCRF/PCF receives the signaling of the CCA (credit control request), the PCRF issues a CCR (credit control response) to answer the PGW and issues the maximum uploading rate and the maximum downloading rate of 100000000bps, and the test terminal verifies that the website can be logged in normally without being influenced.
And II, testing:
when we modify the test number to 190100 on SPR (Subscription Profile Repository, subscription data repository), install the design of the present invention, control the rate on PCRF/PCF to 1Mbps, re-track the number grab packet after restarting the handset, as shown in fig. 5 (B), it can be seen that the test number is on RAR signaling, PCRF/PCF requests the PGW that the maximum upload rate and the maximum download rate of the requested number limit is 1024000bps, the request is successful, PGW replies CCR (credit control response) signaling through GX port, and the reply is SUCCESS rate limiting SUCCESS.
And (3) testing:
the user keeps online, and the service using state of the user is modified to be the speed limit gear of 0Kbps through tent triggering. When the PCF judges that the service use state of the user is changed, the policy plan is triggered again, and the uplink and downlink rates of the user are modified to 0Kbps by issuing session policy control-message updating. The download rate is also verified to be 0Kbps, i.e., the user cannot log into the website normally.
And (4) testing:
in order to check whether the rate control of the 5G service is successful or not, the signaling packet grabbing analysis of the N7 port is tested, the setting gear of the test card of the Internet of things is 190001, namely the issued rate is 1Kbps, the uplink rate and the downlink rate can be controlled at 1Kbps according to the packet grabbing condition of the N7 port,
according to the results of the first test, the second test, the third test and the fourth test, the invention can well limit the speed under the control rate after the reaching amount speed reducing strategy is configured on the PCF.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
