Description

Network switching method and server
Technical Field
The embodiment of the invention relates to the field of mobile communication, in particular to a network switching method and a server.
Background
With the popularization of smart phones and the rapid development of 4G networks, the scale of mobile game business users shows a steady growth trend. The Long Term Evolution (LTE) network has the problems of large delay, data packet loss and the like when carrying the hand-game service, and the user has a prominent stuck problem in the game process, which seriously affects the application experience of the game player and reduces the customer satisfaction.
Handover is a key technology for guaranteeing seamless service connection and user experience in wireless communication. The performance of a handover depends to a large extent on whether the handover can be triggered accurately in time. LTE has more strict QoS (quality of service) guarantee requirements for the carried mobile services, and therefore has higher requirements for handover performance. The existing network switching method comprises the following modes:
firstly, intra-system same-frequency switching: and switching the cells with the same priority and the same frequency by adopting an A3 strategy, namely, when the level of the adjacent cell is higher than that of the serving cell by a certain offset value (for example, the RSRP of the adjacent cell-the RSRP of the serving cell is more than 3dBm), judging to switch to the adjacent cell through A3.
II, inter-frequency switching in the system: switching from a low-priority cell to a high-priority cell, adopting an A2+ A4 strategy, namely starting different frequency measurement when the level of a service cell is lower than an A2 threshold (such as ≤ 90dBm), and judging to switch to a neighbor cell through A4 when the level of the neighbor cell is higher than an A4 threshold (such as ≥ 100dBm) and the duration reaches time lag; switching from the high priority cell to the low priority cell, adopting an A2+ A5 strategy, namely starting the inter-frequency measurement when the serving cell level is lower than an A2 threshold (such as ≦ 90dBm), and judging to switch to the neighbor cell through A5 when the serving cell level is lower than an A5 threshold 1 (such as ≦ -105dBm) and the neighbor cell level is higher than an A5 threshold 2 (such as ≧ -100dBm) and the duration reaches the time lag.
Thirdly, switching different systems: the 4G-2G employs the A2+ B2 policy that inter-system measurements are turned on when the serving cell level is below the A2 threshold (e.g., ≦ -100dBm), the 4G serving cell level is below the B2 threshold 1 (e.g., ≦ -110dBm), and the 2G cell signal level is above the B2 threshold 2 (e.g., ≧ 95dBm), then a handover to 2G is initiated.
However, in the existing network handover methods, data services are all default bearers, the same handover scheme is adopted, actual Qos requirements of different data services on the network are not considered, differentiated services cannot be provided, and user experience is poor.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present specification and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art according to the embodiments of the present disclosure without any inventive step are within the scope of the present disclosure.
Embodiments of the present invention provide a network switching method and a server, so as to solve the problems that the actual Qos requirements of different data services on a network are not considered, differentiated services cannot be provided, and user experience is poor in the prior art. Embodiments of the present invention provide a network switching method, where an execution subject of the method may be, but is not limited to, an application program, a server, or an apparatus or system capable of being configured to execute the method provided by the embodiments of the present invention.
For convenience of description, the following description will be made of an embodiment of the method, taking an execution subject of the method as a server capable of executing the method as an example. It is understood that the implementation of the method by the server is merely an exemplary illustration and should not be construed as a limitation of the method.
Fig. 1 is a flowchart of a network handover method according to an embodiment of the present invention, where the method in fig. 1 may be executed by a server, and as shown in fig. 1, the method may include:
step 101, adjusting the service quality bearer type of the target service.
LTE (Long Term Evolution) defines a series of bearer level quality of service Qos parameters to describe a traffic bearer.
Therefore, the QoS bearer type may include QCI (QoS Class Identifier), gbr (guaranteed Bit rate), MBR (Master Boot Record), and the like.
The QCI is used to measure packet forwarding behavior (e.g., packet loss rate, packet delay budget) of a specific Service Data Flow (SDF). Meanwhile, QCI is applied to GBR and Non-GBR bearers and is used to specify a control bearer level packet forwarding manner (such as scheduling weight, admission threshold, queue management threshold, link layer protocol configuration, etc.) defined in an access node, which are configured in advance by an operator in an access network node.
It can be seen that QCI defines the requirements of throughput, delay, and packet loss rate, as shown in table 1:
TABLE 1
QCI Of the broadband type Priority level Time delay/ms Packet loss ratio (%)
1 GBR 2 100 10％
2 GBR 4 150 1％
3 GBR 3 50 1％
4 GBR 5 300 0.001％
5 non-GBR 1 100 0.001％
6 non-GBR 6 300 1％
7 non-GBR 7 100 0.001％
8 non-GBR 8 300 0.001％
9 non-GBR 9 300 0.001％
And 102, acquiring each influence factor index of the target service from an MR measurement data report of a target network area according to the service quality bearing type of the target service.
Wherein, the influencing factor is a factor influencing the degree of the target service playing process. The influencing factors of the target service may include a time delay and a packet loss rate of a target network region where the target service is located.
The influence factor index is used for representing the playing fluency of the target service in the target network area.
It should be understood that, according to the qos bearer type of the target service, each influencing factor of the target service is determined, and then each influencing factor index of the target service is obtained from the MR measurement data report of the target network area.
MR (Measurement Report) refers to that information is transmitted once every 480ms (470 ms on a signaling channel) on a traffic channel, and these data can be used for network evaluation and optimization.
The MR measurement data report comes from the physical layer and RLC layer of the client (User Experience, abbreviated as UX or UE) and enodeb (Evolved Node B, abbreviated as eNB/base station), and the measurement data report generated by calculation in the radio resource management process.
The MR measurement data report in the embodiment of the present invention relates to the following relevant fields, as shown in table 2:
TABLE 2
Figure BDA0002324742510000061
Figure BDA0002324742510000071
Step 103, determining a reference switching threshold value of the target service according to the actual measurement threshold value of each influencing factor index of the target service, each influencing factor index of the target service and the weight thereof.
And the actually measured threshold value is a threshold value of an influence factor index when the playing fluency of the target service changes. For example, when the playing fluency of the target service is poor, the target service has various influence factor indexes.
Each influencing factor of the target service comprises the time delay and the packet loss rate of a target network area where the target service is located; the actually measured threshold value of each influencing factor index of the target service comprises: the time delay is larger than a second threshold value and/or the packet loss rate is larger than a third threshold value. The second threshold and the third threshold may be set arbitrarily according to actual requirements, and embodiments of the present invention are not limited specifically.
In specific implementation, for example, taking the target service as the mobile game service, the second threshold is less than or equal to 120ms, and the third threshold is less than or equal to 5%. Preferably, the second threshold is equal to or less than 150 ms.
The actual measurement threshold values of the various influencing factor indexes of the target service can be obtained by real-time measurement of a large number of measurement experiments when a worker starts the target service in a target communication area.
The step can be realized specifically by inputting the actual measurement threshold value of each influencing factor index of the target service, each influencing factor index of the target service and the weight thereof into the calculation model, and outputting the reference switching threshold value of the target service. Wherein the computational model may be a model that includes a specific algorithm.
And step 104, determining a real-time switching threshold value of the target service according to each influence factor index and the weight thereof of the target service acquired in real time.
The weight of each influencing factor index of the target service obtained by real-time measurement in this step is consistent with the weight of each influencing factor index in step 103.
And 105, if the real-time switching threshold value is greater than the reference switching threshold value, performing network switching operation for switching from the target network area to an adjacent network area.
The network switching method provided by the embodiment of the invention obtains each influence factor index of the target service from the MR measurement data report of the target network region by adjusting the service quality bearing type of the target service according to the service quality bearing type, determines the reference switching threshold value of the target service according to the actually measured threshold value, each influence factor index and the weight thereof of each influence factor index, determines the real-time switching threshold value of the target service according to each influence factor index and the weight thereof of the target service obtained in real time, and executes the network switching operation of switching from the target network region to the adjacent network region if the real-time switching threshold value is greater than the reference switching threshold value, thereby adjusting the service quality bearing type of the service according to different services, meeting different requirements of different services on the service quality of the network, and providing personalized services, the user experience is improved.
As an embodiment, the target service is a mobile game service, and step 101 may be specifically implemented as:
and adjusting the bearer of the hand-trip service from a default bearer QCI9 to a dedicated bearer QCI 3.
In the embodiment of the invention, the hand-tour service is most sensitive to the end-to-end time delay of the bearer network, and the Qos parameter setting of the hand-tour service is changed to adjust from the default bearer QCI9 to the special bearer QCI3, so that personalized services are provided for different types of services, the playing fluency of the hand-tour service is ensured, service separation is realized, and the user experience is improved.
As an embodiment, before executing step 103, the network handover method provided in the embodiment of the present invention may further include:
and determining the weight of each influence factor index of the target service by adopting an entropy method.
According to the probability theory, the weight of each influence factor index is determined by adopting an entropy method, and the principle is as follows: when the difference between a certain influence factor index and the standard value is large, the entropy value is small, which shows that the effective information quantity provided by the influence factor index is large, the discrimination is high, so the weight setting is also large, the weight of each influence factor index is objectively quantized by adopting an 'entropy value method', and the judgment error caused by manually setting the factor weight is avoided.
Specifically, the calculation process by the entropy method is as follows:
for example, assume that m cells have n influencing factor indicators forming an indicator matrix D:
Figure BDA0002324742510000091
obtaining a matrix R through normalization processing:
Figure BDA0002324742510000092
the entropy value E of each column can be calculatedj：
Figure BDA0002324742510000093
The closer E is to 1, the more difficult the influence factor index is to be distinguished, and the corresponding distinguishing degree FjComprises the following steps:
Fj＝1-Ej
the weight W of each influencer indicatorjComprises the following steps:
Figure BDA0002324742510000094
as an embodiment, after step 101 is executed, the network handover method provided in the embodiment of the present invention may further include:
determining each influence factor of the target service according to the service quality bearing type of the target service;
determining the hierarchical relationship of each influence factor of the target service according to the attribute of each influence factor of the target service;
constructing a perception model of the target service according to the hierarchical relation of all the influence factors of the target service, wherein the perception model comprises all the influence factors of the target service;
determining each influence factor of the target service according to the service quality bearing type of the target service; according to the attribute of each influencing factor, utilizing an Analytic Hierarchy Process (AHP for short) to decompose a plurality of factors related to perception of the target service into a plurality of layers from top to bottom according to different attributes, wherein the factors of the same layer belong to or influence the factors of the upper layer, and simultaneously dominate the factors of the next layer or are influenced by the factors of the lower layer so as to determine the hierarchical relationship of each influencing factor of the target service and construct a perception model of the target service.
For example, it is assumed that each influencing factor includes delay, coverage, quality, load, packet loss rate, uplink packet loss rate, downlink packet loss rate, and the like. Based on the attributes of the influencing factors, the hierarchical relationship of the influencing factors of the target service is obtained by using an AHP analytic hierarchy process, and a perception model of the target service is obtained, as shown in FIG. 2.
It should be added that after the perceptual model of the target service is established, the weight of each influencing factor in each layer and the weight of each layer can be determined by using an entropy method. The specific calculation method is detailed in the related contents of the above embodiments, and is not described herein again. And after calculating the weight of each layer, performing total hierarchical ranking on each layer, wherein the total hierarchical ranking refers to a process of determining the relative importance of all influencing factors of a certain layer to a total target.
By way of example, assume that as shown in figure 3,
m influencing factors C of C layer1，c2，……，cmOrdering the overall target o as a eigenvector w ═ a1，a2，……，am
P layer n influencing factors on upper layer cjIs ordered into a feature vector b1j，b2j，……，bnj(j＝1,2，……，m)
The total hierarchical ordering of the P layers is as follows: p1：a1b11+a2b12+……amb1m
P2：a1b21+a2b22+……amb2m
……
Pn：a1bn1+a2bn2+……ambnm
That is, the weight of the total target o due to the i influencing factors of the P layer is:
Figure BDA0002324742510000111
if expressed in tabular form, as shown in table 3;
TABLE 3
Figure BDA0002324742510000112
Step 102 may be specifically implemented as:
and acquiring each influence factor index of each influence factor of the target service in the perception model from an MR measurement data report of a target network area.
The embodiment of the invention realizes decision analysis by an AHP analytic hierarchy process, and determines each influence factor of the target service according to the service quality bearing type of the target service; determining the hierarchical relationship of each influence factor of the target service according to the attribute of each influence factor of the target service; and establishing a perception model of the target service according to the hierarchical relationship of the influence factors of the target service, and acquiring the influence factor indexes of the influence factors of the target service in the perception model from the MR measurement data report of the target network region, so as to establish a mapping relationship between the MR measurement data report and the perception model of the target service.
As an embodiment, step 104 may be specifically implemented as:

and switching the target network area to the pilot frequency network area with the maximum level value according to the ranking of the level values of the pilot frequency network areas.
Background: in the above embodiment of the invention, the MR measurement data report is that the eNB base station periodically notifies the UE of the MR measurement data through the measConfig cell carried in the rrcconnectionreconfiguration message; acquiring each influence factor index of the target service from the MR measurement data report according to the service quality bearing type of the target, and determining a reference switching threshold value of the target service according to the actual measurement threshold value of each influence factor index, each influence factor index and the weight thereof; and then determining that the playing fluency of the target service is poor in the target network communication area according to the fact that the real-time switching threshold value is larger than the reference switching threshold value, and then, the target service is in a pause phenomenon, and at the moment, executing network switching operation.
The technical solution provided by the embodiment of the present invention specifically implements the network switching operation when the target service is stuck: and in a preset time period, if the frequency that the real-time switching threshold value is larger than the reference switching threshold value is determined to exceed the threshold value, selecting a plurality of pilot frequency network areas with different frequencies from the target network area from the adjacent network areas, and switching the target network area to the pilot frequency network area with the maximum level value according to the sequence of the level values of the plurality of pilot frequency network areas.

Step 403, if the real-time switching threshold value is greater than the reference switching threshold value, the stuck counter + 1; step 404, determining whether the number of times of calking is more than 3 within 5s, if yes, executing step 405; if not, go to step 401; step 405, if the number of times of calking is more than 3 within 5s, triggering the switching. And step 406, the eNB base station performs neighbor cell clipping according to the information of the neighboring network region reported by the MR measurement data, performs neighbor cell sorting according to the frequency priority and level value of the neighboring network region, and performs blind handover with the neighboring network region sorted in the front as a handover target.
Preferably, the specific implementation of the technical solution provided in the embodiment of the present invention for performing a network switching operation when a target service is stuck may be as follows: and in a preset time period, if the times that the real-time switching threshold value is larger than the reference switching threshold value are continuously determined to exceed the threshold value, selecting a plurality of pilot frequency network areas with different frequencies from the target network area from the adjacent network areas, and switching the target network area to the pilot frequency network area with the maximum level value according to the sequence of the level values of the pilot frequency network areas.
