Description
Technical Field
The present disclosure relates to the field of communications, and in particular, to a method and a system for managing and controlling traffic.
Background
With the rapid development of the mobile internet and the popularization of the intelligent terminal, the traffic is gradually becoming an indispensable public resource of the society. The promotion of the non-flow-limiting package greatly stimulates the demand of users for flow. At present, a package without flow limitation has become the mainstream choice of the market, and more users use flow to play videos, mobile games, mobile client APP shopping and other activities. However, the centralized explosion of massive data also presents a huge challenge to the carrying capacity of the operator network. Data shows that the network traffic of a certain operator is increased by 5 times within one year when domestic unlimited flow packages are online. Under the background of large outbreak of a package without flow limitation, a scene of high telephone traffic exists in some time periods in a hot spot area, and if the network capacity is instantaneously insufficient, the user experience is reduced, so that the risk of complaint is brought to an operator.
The current management and control means of operators for packages without flow limitation is simple. According to the general flow, the Charging system is responsible for counting user traffic information, when it is found that the total traffic of users reaches the agreed conditions, a speed reduction instruction is issued to a Policy and Charging Rules Function (PCRF) through a Sy interface, the PCRF completes a Policy control decision Function and issues a low-speed rate Policy for the users, and a Public Data Network GateWay (PGW)/Serving GateWay (SGW) is responsible for the specific execution of the Policy. By reducing the internet access speed of the user, the network load is reduced to a reasonable range.
However, the scheme can only control a single user, and cannot adjust according to the actual situation of the network according to time and place, and in some hot spot areas such as colleges and universities, and busy hours in business circles, users in the area do not reach the agreed speed reduction condition at the beginning of the month, the users can surf the internet at a high speed, the large flow causes the community congestion, the perception of the users surfing the internet is extremely poor, and the users mistakenly think that the operators limit the speed maliciously. This misunderstanding carries with it the risk of complaints for the operator, increasing the labor cost of the operator's complaint handling. In addition, in the conventional manner, an operator network lacks an efficient and flexible management and control means, and cannot selectively perform bandwidth control on part of users or part of services, so as to relieve/slow down the cell congestion state.

For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
Fig. 1 is a schematic flow chart of an embodiment of a method for managing and controlling traffic according to the present disclosure.
In step 110, the PGW determines the round-trip delay difference by detecting the round-trip delay information in the terminal packet header. For example, the PGW records the first round trip delay RTT in the downlink data packet of the terminalA(ii) a And receiving the second round trip time RTT in the response message returned by the terminalB(ii) a According to the second round trip delay RTTBAnd a first round trip time RTTADetermining the round trip time difference delta RTT as RTTB-RTTA。
In step 120, the PGW determines whether the round trip delay difference is greater than a reference value. The PGW may periodically learn RTT information through a locally configured RTT reference value learning function, so as to obtain the RTT reference value in the detection period.
In step 130, if the round-trip delay difference is greater than the reference value, the PGW determines that the area where the terminal is located is a hot spot area.
In step 140, the PCRF adjusts the network rate of the terminal in the hotspot area. For example, the PGW issues the location information of the hotspot Area to a third-party server, so that the third-party server updates the location information of the hotspot Area to a PRA (Presence Reporting Area) list of an MME (mobility management Entity); and the PCRF adjusts the network rate of the terminal in the hot spot area according to the PRA state reported by the terminal, namely, the bandwidth control is carried out on part of users or specified services.
In the embodiment, a cell congestion deployment mode based on core network perception is realized, and bandwidth control is selectively performed on the terminal in the hot spot area, so that the purpose of relieving or alleviating the cell congestion state is achieved, and the service experience of a user is effectively guaranteed.
Fig. 2 is a schematic flow chart of another embodiment of the traffic control method according to the present disclosure. After performing the steps of fig. 1, the method may further perform the following steps:
in step 210, if the round-trip delay difference is smaller than or equal to the reference value, the PGW determines that the hotspot area is recovered to be a non-hotspot area.
In step 220, the PGW issues the non-hotspot area location information to the third-party server, so that the third-party server deletes the non-hotspot area location information from the PRA list of the MME.
In step 230, the PCRF recovers the network rate of the terminal in the non-hotspot area according to the PRA status reported by the terminal.
In this embodiment, when the network traffic for the terminal user in the hot spot area is restored to the idle time level, the hot spot area is restored to the non-hot spot area in time, and the network rate of the terminal in the non-hot spot area is restored, so that the user perception is improved, and the complaint risk of the user caused by poor perception is reduced.
Fig. 3 is a flowchart illustrating a method for managing traffic according to still another embodiment of the present disclosure. When a large number of high-rate users enter a certain area, a large flow instantly rushing in under the area causes network congestion.
In step 310, the PGW records RTT in downlink data packet arriving at the local terminalA。
In step 320, the PGW forwards the downlink data packet to the terminal UE.
In step 330, after receiving the downlink data packet, the UE returns an acknowledgement response message to the PGW.
In step 340, the PGW records RTT in the response messageB。
In step 350, the PGW determines that the round trip delay difference Δ RTT is equal to RTTB-RTTA。
At step 360, the PGW compares Δ RTT to a reference value. The PGW collects and counts RTT information of user TCP messages in a cell, and configures an RTT detection period and a self-learning function, so as to obtain a reference value of the RTT.
In step 370, if the PGW detects that the Δ RTT is greater than the reference value, the PGW extracts the terminal location information according to the context of the terminal, and sends the terminal location information to the third-party server. The third party server is for example a professional webmaster. For example, the PGW extracts location information such as an ECGI (Cell Global Identifier)/TAI (Tracking Area identity) of the end user, records the changed location information, and sends the location information to the third-party server by ftp.
In step 380, the third-party server has configured the script for modifying the PRA region on the MME in advance, and according to the change of the received location information, the modified script is issued to the MME, thereby completing the dynamic configuration of the PRA.
In step 390, the MME starts the location reporting function, and synchronizes the new PRA status of the terminal to the PGW.
In step 3100, the PGW reports the PRA status of the terminal to the PCRF in the CCR request.
In step 3110, the PCRF makes a policy decision for the terminal in the hotspot area according to the PRA status reported by the terminal, and initiates policy update.
In step 3120, the PGW adjusts the terminal rate to a reasonable interval, and completes the management and control of the hot spot area.
When a large number of high-rate users exit the hot spot area, the following steps can be further executed:
in step 3130, if the PGW detects that Δ RTT is less than or equal to the reference value, the PGW restores the traffic of the hotspot area to an idle level, that is, the hotspot area is restored to a non-hotspot area, and sends location information of the non-hotspot area to the third-party server.
In step 3140, the third-party server deletes the non-hot-spot area from the PRA list of the MME using a pre-configured script.
In step 3150, the MME sends PRA recovery status information of the non-hotspot area to the PGW.
In step 3160, the PGW reports the PRA status of the terminal to the PCRF.
In step 3170, after the PRA list is updated, the PCRF recovers the user rate according to the user PRA status reported again by the PGW.
At step 3180, the PGW performs a rate recovery action on the non-hotspot zone.
In this embodiment, the PGW periodically detects an RTT field in a user packet header, calculates a difference value, compares the difference value with an RTT reference value, determines that the area is a hotspot area, updates the hotspot area to the PRA-list of the MME through the third-party server, and reasonably adjusts the rate of the terminal entering the PRA management and control area by the PCRF, so as to solve the problem of congestion in the hotspot area, and timely replies the rate of the terminal in the non-hotspot area when the hotspot area is recovered to the non-hotspot area. The embodiment gives full play to the core control function of the core network for network flow regulation, utilizes the advantages of the network to the greatest extent, can sense the busy cell without the help of a wireless side network pipe, and has guiding significance for network autonomous optimization.
In addition, the invention can effectively improve the utilization rate and the benefit of wireless resources, clear limited resources to high-value services of high-value users, effectively improve the user perception and reduce the complaint risk of the users caused by poor perception.

The PGW410 needs to be upgraded and modified, the PGW needs to upgrade an RTT detection module, collects and counts RTT information of user TCP messages in a cell, and configures an RTT detection period and a self-learning function, so that a reference value of RTT is obtained.
For example, the PGW 420 records the first round trip delay RTT in the downlink data packet of the terminalA(ii) a And receiving the second round trip time RTT in the response message returned by the terminalB(ii) a According to the second round trip delay RTTBAnd a first round trip time RTTADetermining the round trip time difference delta RTT as RTTB-RTTAAnd if the round-trip delay difference is larger than the reference value, the PGW determines that the area where the terminal is located is a hot spot area. The PGW may also send the hotspot area location information to a third-party server, so that the third-party server updates the hotspot area location information to the PRA list of the MME. And the connection between the third server and the PGW and the MME is opened, so that the professional network manager can issue the configuration and modify the PRA list of the MME.
The PCRF 420 is configured to adjust a network rate of the terminal in the hot spot area. For example, the PCRF 420 adjusts the network rate of the terminal in the hot spot area according to the PRA status reported by the terminal.
In this embodiment, the hot spot area can be determined in time by the cell congestion deployment mode perceived by the core network, so as to adjust the network rate of the terminal in the hot spot area, thereby achieving the purpose of relieving or alleviating the cell congestion state.
In another embodiment of the present disclosure, the PGW410 is further configured to determine that the hotspot area is recovered to a non-hotspot area if the round-trip delay difference is less than or equal to the reference value, and the PGW sends the location information of the non-hotspot area to the third-party server, so that the third-party server deletes the location information of the non-hotspot area from the PRA list of the MME.
The PCRF 420 is configured to recover the network rate of the terminal in the non-hotspot area according to the PRA status reported by the terminal.
In this embodiment, when the network traffic for the terminal user in the hot spot area is restored to the idle time level, the hot spot area is restored to the non-hot spot area in time, and the network rate of the terminal in the non-hot spot area is restored, so that the user perception is improved, and the complaint risk of the user caused by poor perception is reduced.
