Description
Technical Field
The invention relates to the technical field of communication, in particular to a network service management and control method and a network service management and control system.
Background
With the continuous development of science and technology and society, the emergence of various network services brings great convenience to the work and life of people. In recent years, network services have been increased explosively, so that in some places with dense people flow (such as concert venues, train stations, etc.), the phenomenon that the user experience is obviously affected due to high network service load is likely to occur.
At present, the following three ways are usually adopted to solve the drawback of poor user experience in high network traffic load areas: firstly, the network capacity is increased by means of capacity expansion, such as adding new frequency spectrum; secondly, users with high network traffic are migrated to a cell with low network traffic in a load balancing manner; and thirdly, releasing the network resources in advance by means of timer adjustment, such as by modifying a network parameter timer.
However, in the implementation process, the inventor finds that the following defects exist in the prior art: for the capacity expansion mode of the newly added spectrum, due to the limitation of spectrum resources and the adaptation limitation of the antenna, the combiner and the like to the frequency band, the application range and the effect of the implementation mode are very limited. Moreover, the adoption of the method needs to be deployed in advance, so that the method cannot process the sudden high network load in time; for the implementation of load balancing, it cannot be applied to the situation where high network traffic load occurs in multiple cells; for the implementation of the timer adjustment, the number of times of establishing and releasing a large number of signaling channels is increased, which causes an increase in the load of the signaling bearer and further poses a threat to the secure operation of the base station.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a flowchart illustrating a network traffic control method according to an embodiment of the present invention. Different from the technical means of capacity expansion, load balancing and timer adjustment in the prior art, the network service management and control method provided in this embodiment is an optimization scheme for network resource scheduling in a high network service load area, and specifically performs differentiated network resource scheduling for different network service types of target users in the high network service load area.
As shown in fig. 1, the method includes:
step S110, at least one target user corresponding to the high network service load area is determined.
The high network traffic load area generally includes: train stations, hospitals, concert venues, holiday tourist areas, etc. The embodiment does not limit the specific type of the high network traffic load area, and a person skilled in the art may determine the high network traffic load area according to actual requirements, for example, an area where the number of network traffic per unit time and/or unit area is greater than a preset number may be determined as the high network traffic load area.
Further, at least one target user corresponding to the high network service load area is determined. Optionally, at least one target user corresponding to the high network traffic load area may be determined based on the geographic location dimension information and/or the time dimension information. In order to ensure the accuracy of the obtained target users, the target users corresponding to the high network service load area can be comprehensively determined according to the two dimensional information of the geographical position dimensional information and the time dimensional information.
In a specific implementation process, at least one candidate user may be determined first, and further, a real-time reporting instruction of the regional location information is issued for each candidate user, so that the location information reported by the candidate user can be obtained in real time. And when the position information reported by the candidate user is in the geographical position area range corresponding to the high network service load area and the time of the candidate user for reporting the position information currently is in the time range corresponding to the high network service load area, determining that the candidate user is the target user corresponding to the high network service load area.
Step S120, for each target user, performing service type identification on the network service currently used by the target user, and determining the service type of the network service currently used by the target user.
Specifically, after at least one target user corresponding to the high network service load area is determined, the type of the network service currently used by each target user may be identified, so as to determine the service type of the network service currently used by the target user. In this embodiment, the specific service type identification manner is not limited, and a person skilled in the art may select a corresponding identification manner according to an actual situation.
The service types described in this embodiment mainly include: streaming media service types (e.g., video service, etc.), web browsing service types, instant messaging interaction service types (e.g., messaging interaction service in social software, etc.), and/or other service types, among others.
Step S130, allocating a corresponding service quality grade identifier to the network service currently used by the target user according to the service type of the network service currently used by the target user.
In order to facilitate subsequent differentiated network resource scheduling of different network services of the target user, in this step, after determining the service type of the network service currently used by the target user in step S120, the target user is assigned a quality of service Class Identifier (QCI, qoS Class Identifier) matching the service type of the network service currently used by the target user.
Step S140, performing differentiated network resource scheduling according to the qos class identifier corresponding to the network service currently used by each target user of the at least one target user.
Specifically, different network services of the target user are subjected to differentiated network resource scheduling. In this embodiment, the quality of service class identifier corresponding to the network service may belong to a limit class QCI or a guarantee class QCI, and when the quality of service class identifier corresponding to the network service is the limit class QCI, the resource occupation of the network service may be limited by reducing the priority of the network service or controlling the network rate of the network service so that the network rate is lower than a first preset rate; and when the service quality grade mark corresponding to the network service is the guarantee class QCI, the resource occupation of the network service can be limited by improving the priority of the network service or controlling the network rate of the network service to ensure that the network rate is not lower than a second preset rate. In this embodiment, a constraint class QCI is generally allocated for large packet services such as video streaming, and a guarantee class QCI is allocated for small packet services such as payment. This embodiment is not limited to this.
For example, for a service type that a single user needs to consume more network resources, such as a video stream, a service quality level identifier of QCI-7 may be configured for the service type, and then, according to the service quality level identifier of QCI-7, the network resources occupied by the network services of the service type are limited, and then, the network resources saved by limiting the network resources occupied by the network services of the service type are provided for network services of service types, such as web browsing, social software communication, and the like, so as to ensure network service requirements of more users.
The following specifically explains the implementation process of the present embodiment by using a specific example:
for a railway station ticket gate A2A3 cell, network users within the coverage area of the A2A3 cell and with network service use time in a peak period (such as 6 o 'clock-23 o' clock earlier) are determined as target users, and the service types currently used by the target users are determined. If the service type currently used by a certain target user is a video stream service type, distributing a service quality grade identifier of QCI-7 for the certain target user; if the service type currently used by a certain target user is a payment type, allocating a QCI-6 service quality grade identifier to the target user; and further carrying out differentiated network resource scheduling according to the service quality grade identification of each QCI-7. For example, for the service quality class identifier of QCI-7, the network resources occupied by this type of network service can be limited by limiting the highest bandwidth. If the total rate bandwidth N per second of the cell is 70mbps, the number a of streaming media users of the cell is 5, the number b of HTTP browsing users is 15, the number c of social software users is 20, and the number d of other service users is 15, wherein the resource alpha occupied by a streaming media service single user is 5mbps, the resource beta occupied by the HTTP browsing service single user is 1.2mbps, the resource theta occupied by the social service single user is 0.6mbps, and the bandwidth resource gamma occupied by other service single users is 1mbps, and if the rate of the streaming media single user is limited to 2mbps from 5mbps, the total bandwidth resources occupied by all users of the streaming media are reduced to 10mbps from 25mbps, the spare 15mbps resources can be accessed to 12 HTTP users or 30 social services or 15 other services more; for the QCI-6 service quality grade identification, a mode of ensuring the lowest bandwidth can be adopted to ensure the normal implementation of the network service.
Therefore, in the embodiment, the target user corresponding to the high network service load area is determined firstly; further carrying out service type identification on the network service currently used by each target user, determining the service type of the network service currently used by the target user, and distributing a corresponding service quality grade identifier for the network service currently used by the target user according to the service type of the network service currently used by the target user; and carrying out differentiated network resource scheduling according to the service quality grade identification corresponding to the network service currently used by each target user. The scheme can reduce the network load in a high network service load area, and can be suitable for a scene with sudden high network service load and high network service load in a plurality of cells; and the method is not limited by hardware resources such as frequency resources and antennas, and additional signaling load is not generated, thereby ensuring the safe operation of the base station.
Fig. 2 is a flowchart illustrating a network traffic control method according to another embodiment of the present invention. The method for managing and controlling network traffic provided by this embodiment is further optimized for the embodiment of the method shown in fig. 1. In this embodiment, according to the hardware characteristics of the core network and the wireless side, the core network and the wireless side execute corresponding steps to implement network service management and control in the high network service load area.
As shown in fig. 2, the method includes:
step S210, the PCRF determines at least one target user corresponding to the high network traffic load region.
In this embodiment, step S210 to step S220 are executed by a PCC (Policy and Charging Control) architecture in a core network (specifically, an LTE core network). In a specific implementation process, at least one target user corresponding to a high network traffic load area is determined by a PCRF (Policy and Charging Rule Function) node in the PCC architecture.
In a specific implementation process, a policy determining method for a target user corresponding to a high network service load area is pre-configured in a PCRF node. Wherein, the determining policy includes: a user type dimension policy, a geographic location dimension policy, and/or a time dimension policy, etc. And when the candidate user meets the user type dimension strategy, the geographic position dimension strategy and/or the time dimension strategy, determining that the candidate user is a target user corresponding to the high network service load area.
In an alternative embodiment, the high network traffic load area may be multiple. Then, for each high network traffic load region, a determination policy of the target user corresponding to the high network traffic load region may be preconfigured in the PCRF node. For example, for a high network traffic load area, i.e. a certain train station, the corresponding target user determination policy may be: the user is a mobile network user, the position is positioned in the coverage range of the P1 base station, and the time is from 6 points earlier to 11 points later; for a high network service load area, such as a concert venue, the corresponding target user determination policy may be: the user is a mobile network user, the position is in the coverage range of the P2 base station, the time is 8-10 late, and the like.
Therefore, the target users corresponding to the high network service load area can be dynamically adjusted by dynamically increasing, decreasing or adjusting the determination strategy of the target users corresponding to the high network service load area, so that different network resource scheduling results are obtained. Therefore, the embodiment has high expandability. And is suitable for sudden high network service load scenes.
Step S220, for each target user, the PGW parses the data packet corresponding to the target user, determines the service type of the network service currently used by the target user according to the parsing result, and allocates a corresponding service quality level identifier to the network service currently used by the target user.
In this embodiment, a Policy and Charging Enforcement Function (PCEF) node in the PCC architecture may determine a service type of a network service currently used by a target user, and allocate a corresponding quality of service class identifier to the network service currently used by the target user. Specifically, the PCEF node function may be performed by a PGW (PDN GateWay).
In this embodiment, after the PCRF determines that a candidate user is a target user corresponding to a high network service load area, a corresponding instruction may be issued to the PGW through a Gx (Diameter protocol) interface between the PCRF and the PCEF (specifically, PGW), so as to trigger the PGW to identify a service type of a network service currently used by the target user.
In the process of identifying the service type of the network service currently used by the target user by the PGW, the uplink data packet and/or the downlink data packet of the target user are/is firstly analyzed to obtain user message data corresponding to the target user. The parsing process includes three-four layer parsing (e.g., three-layer parsing and four-layer parsing), and protocol identification (e.g., known port identification, feature word protocol identification, seven-layer parsing, etc.). The obtained user message data comprises: source IP address, destination IP address, IP protocol type (TCP, UDP, ICMP, or the like), source port number, destination port number, known port protocol, signature word protocol, or the like; further, the user message data obtained by analysis is compared with a preset feature library, where the preset feature library may include a set of multiple application layer protocols and unique identification features of an application program, and the like, and the specific construction method of the preset feature library is not limited in this embodiment; finally, according to the comparison result, the service type of the network service currently used by the target user can be determined. For example, the service type of the network service currently used by the user is determined as the payment type.
Optionally, in order to effectively reduce the load in the high network service load area and improve the user experience, when the service type of the network service currently used by the target user is determined, the implementation performs fine-grained identification on the service type of the network service currently used by the target user. That is, through this step, the application type to which the network service currently used by the target user belongs, the specific network service in the application type, and the like can be specifically determined, and if it is determined that the service type corresponding to the user1 is: a payment transaction for ticketing apps, and so on.
Further, according to the service type of the network service currently used by the target user, a corresponding service quality grade identifier is allocated to the network service currently used by the target user. For example, a quality of service class identifier of QCI-6 may be assigned for payment type, a quality of service class identifier of QCI-7 may be assigned for video stream type, and so on.
Step S230, the base station performs differentiated network resource scheduling according to the qos class identifier corresponding to the network service currently used by each target user in the at least one target user.
In a specific implementation process, a base station (for example, an eNodeB) may obtain a quality of service class identifier corresponding to a network service currently used by a target user and issued by a core network, and perform differentiated network resource scheduling according to the quality of service class identifier corresponding to the network service currently used by each target user in at least one target user by using at least one management and control policy. The management policy specifically includes a static management policy and/or a dynamic management policy, and the like.
For the static management and control strategy, differentiated network resource scheduling can be performed according to the scheduling weight factor matched with the service quality grade identification corresponding to the network service currently used by each target user in at least one target user. Specifically, different quality of service class identities are configured with corresponding scheduling weight factors. In the actual implementation process, the actual scheduling weight of the Non-GBR service is related to the channel quality of the user, the historical transmission rate of the user, the scheduling weight factor matched with the service quality grade identifier corresponding to the service, the waiting scheduling delay of the service, the available network resources and the like, so that the actual scheduling weight of the service is determined through multiple dimensions, and the rationality of resource scheduling is further improved. In a specific implementation process, the actual scheduling weight of the Non-GBR service positively correlates with the channel quality of the user, negatively correlates with the historical transmission rate of the user, positively correlates with a scheduling weight factor matched with the service quality grade identifier corresponding to the service, positively correlates with the waiting scheduling delay of the service, and positively correlates with the available network resources. It can be seen that the scheduling weight factors matched with the service quality grade identifications are different, and the final scheduling weights of the network services corresponding to the service quality grade identifications are different, so that differentiated scheduling of different types of services is realized.
For example, for a video streaming service, the qos class identifier of the video streaming service may be configured as QCI-7, and the scheduling weight factor corresponding to the qos class identifier of QCI-7 is 0.5, and the scheduling weight factor corresponding to the qos class identifiers of other services is 1, so that the probability of scheduling the video streaming service and other services is reduced from 1:1 to 0.5 when the channel quality, the historical transmission rate of the user, the waiting scheduling delay of the service, and the available network resources are all the same. Therefore, the resource occupation of the video streaming service is limited, and the use experience of most users on the packet service (such as webpage browsing, social software information sending and the like) is guaranteed.
Optionally, in the static management and control policy, in order to ensure normal operation of the preset network service in the preset high network service load area, in this embodiment, the preset network service in the preset high network service load area has a corresponding scheduling weight minimum value, that is, an actual scheduling weight of the preset network service is always greater than or equal to the scheduling weight minimum value. For example, in a high network service load area, such as a train station, network services related to ticketing (such as services of ticket buying, ticket refunding, ticket change and the like by purchasing software) have a minimum scheduling weight value, so that the network services related to ticketing can always have a higher scheduling weight, normal use experience of the network services related to ticketing by a user is guaranteed, and user experience is further improved.
For the dynamic management and control strategy, differentiated network resource scheduling can be performed according to the rate threshold matched with the service quality grade identification corresponding to the network service currently used by the target user. In the actual implementation process, some service quality level identifiers have matched rate thresholds, that is, the network service corresponding to the service quality level identifier is the network service to be limited. For example, it may be determined whether to configure a rate threshold for the quality of service class identifiers QCI-6, QCI-7, QCI-8, and QCI-9, where the rate thresholds for the quality of service class identifiers may be the same or different.
Specifically, in order to implement reasonable scheduling of network resources, the service load is reduced and the user experience is improved. In this embodiment, dynamic resource scheduling is performed based on the number of users configured with a rate adjustment identifier in a cell and the resource utilization rate in the cell (where the resource utilization rate is specifically a PRB utilization rate), and the specific implementation manner is as follows:
firstly, determining a service quality grade identification configured with a rate regulation identification, and determining the number of users configured with the rate regulation identification according to the number of the service quality grade identifications configured with the rate regulation identification; when the resource utilization rate in the cell is greater than a preset utilization rate threshold and the number of users corresponding to the configured rate regulation and control identification is greater than a preset user number threshold, scheduling network resources according to a preset rate; and when the resource utilization rate in the cell is less than or equal to a preset utilization rate threshold and/or the number of users corresponding to the configured rate regulation identification is less than or equal to a preset user number threshold, scheduling the network resources according to the account opening rate. By adopting the management and control strategy, network resource scheduling can be carried out on the network service configured with the rate regulation and control identification according to a preset rate (wherein the preset rate is lower than an account opening rate) under the condition of higher load, so that the resource occupation of the corresponding network service is limited; and when the load is lower, restoring the rate of the network service to the account opening rate.
