It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Existing cells may be divided into FDD cells using Frequency Division Duplexing (FDD) technology and TDD cells using TDD technology, depending on the duplex communication mode used. The FDD cell covers an FDD network, and the TDD cell covers a TDD network.
In practice, the FDD and TDD networks will cover the same area at the same time. The users in the area are connected with an FDD network or a TDD network. Specifically, if a user connects to an FDD network, the user may be referred to as an FDD network user. If a user is connected to the TDD network, the user may be referred to as a TDD network user.
However, when the TDD network is subject to atmospheric fluctuations, the traffic of the TDD network users can be greatly affected.
Accordingly, there is a need for a method, apparatus, device and medium that can effectively cope with atmospheric waveguide interference
For better understanding of the present invention, a service migration method, an apparatus, a device and a medium for dealing with atmospheric waveguide interference according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be noted that these embodiments are not intended to limit the scope of the present disclosure.
Fig. 1 is a schematic flow chart illustrating a traffic migration method coping with atmospheric waveguide interference according to an embodiment of the present invention. As shown in fig. 1, the service migration method 100 for dealing with atmospheric waveguide interference in the present embodiment may include the following steps S120 and S130:
and S120, determining that the TDD network covering the current area is interfered by the atmospheric waveguide.
In some embodiments of the present invention, in order to accurately determine the atmospheric waveguide interference, before S120, the service migration method 100 for dealing with the atmospheric waveguide interference further includes:
s111, obtain an interference signal strength of a Physical Broadcast Channel (PBCH) allocated to the synchronization signal in the TDD network.
Wherein the synchronization signal in S111 includes: primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS).
In some embodiments, the SSS signals and PSS signals occupy the middle 6 Physical Resource Blocks (PRBs) in the frequency domain of the TDD network.
As an example, a TDD network may employ 20 mhz on-frequency networking. Long Term Evolution (LTE) signals in the frequency domain are combined from thousands of subcarriers, each having a bandwidth of 15 khz. That is, a 20 mhz bandwidth contains 1200 subcarriers. The physical resources of LTE can be defined from two dimensions of time and frequency, and each physical resource block consists of 12 consecutive subcarriers in the frequency domain, which is 1 PRB. Accordingly, a bandwidth of 20 mhz contains 100 PRB.
When the interference signal strength of 46 th PRB to 52 th PRB on the TDD network is monitored to be constantly interfered and the interference signal strength is obviously higher than that of the rest 94 PRBs, the TDD network is determined to be interfered by the atmospheric waveguide.
In some embodiments, a specific implementation of S111 may include: and monitoring and counting the interference level of the TDD network. For example, the interference level of each PRB in the TDD network 100 PRBs is monitored.
And S112, judging whether the intensity of the interference signal exceeds a preset interference signal intensity threshold value.
In some embodiments, the interference signal strength threshold may be preset based on the characteristics of the TDD network when the atmospheric waveguide interferes.
As a specific example, the interference signal strength threshold may be set to a value of-110 dB.
It should be noted that, after S112, if the interference signal strength of the PBCH corresponding to the synchronization signal does not exceed the preset interference strength threshold, it is determined that the current TDD network is subjected to the normal interference, and the processing is performed according to the processing method for the normal interference.
And S113, determining that the TDD network corresponding to the current area is interfered by the atmospheric waveguide when the intensity of the interference signals exceeds a preset interference signal intensity threshold value.
In some embodiments, it may be determined whether the interference signal strengths of the PBCHs corresponding to the synchronization signals all exceed a preset interference signal strength threshold. And if the interference signals exceed the preset interference signal intensity threshold, determining that the TDD network covering the current area is interfered by the atmospheric waveguide.
As a specific example, when the measured interference signal strength of the 6 PRBs corresponding to the synchronization signal is higher than the preset interference signal strength threshold, it is determined that the TDD network covering the current area is interfered by the atmospheric waveguide.
S130, the non-GBR service of the TDD network user in the current area is transferred to the FDD network covering the current area.
The TDD network user means a user connected to the TDD network.
According to the service migration method, device, equipment and medium for dealing with the atmospheric waveguide interference in the embodiment of the invention, when the TDD network is determined to be subjected to atmospheric fluctuation interference, non-GBR services of TDD network users can be migrated to an FDD network. The FDD network can avoid atmospheric interference, non-GBR services of TDD network users are transferred to the FDD network, and the response capability to atmospheric waveguide services can be improved.
In some embodiments of the present invention, a specific manner for migrating non-GBR traffic to the FDD network may be: and migrating the non-GBR service to the FDD network in a cell switching or cell reselection mode.
Specifically, under normal circumstances, the reselection priority and handover priority of the TDD network are both higher than FDD. Users in the current region preferentially camp on the TDD network.
When the TDD network covering the current area is interfered by atmospheric fluctuation, the switching priority and/or the reselection priority of the FDD network covering the current area may be increased, and the increased switching priority and/or the increased reselection priority of the FDD network is higher than that of the TDD network, so that the user in the current area preferentially resides in the FDD network.
It should be noted that, in the embodiment of the present invention, after determining that the TDD network is subjected to the atmospheric air waveguide, in addition to performing S130, the power of the TDD network may be reduced. Specifically, the transmit power of the TDD cell corresponding to the TDD network is reduced.
In some embodiments of the present invention, in order to further ensure that the service originally in the TDD network is not affected by the atmospheric fluctuation interference, after S120, the service migration method 100 for dealing with the atmospheric waveguide interference further includes:
s140, the Guaranteed Bit Rate (GBR) service using the TDD network in the current region is switched to the FDD network.
And the QCI value of the GBR service is less than 5.
In some embodiments of the present invention, the GBR traffic is migrated in the same manner as non-GBR traffic.
Among them, the GBR service has a high requirement on the implementation, and the GBR service is preferably migrated in a cell handover manner.
In some embodiments of the present invention, table 1 shows the traffic of an existing LTE network. The QCI is a parameter used by the system to identify the transmission characteristics of the service data packets. The GBR service means a service with a high requirement on real-time performance, and a minimum bit rate needs to be guaranteed for the service. The non-GBR service has low requirement on real-time performance, and the minimum bit rate does not need to be ensured for the service.
The existing network deploys 5 QCI values, wherein the QCI value of the GBR service is 1 to 3.
The VoLTE video of the GBR service is different from the streaming media video of the non-GBR service. The VoLTE video represents a video call based on a VoLTE network, and the streaming media video comprises services of watching, downloading network video and the like.
It should be noted that, according to the allocation manner in table 1, most users and services are currently concentrated on the same QCI, that is, share the same resource. Due to the differentiation between the service types and the user types, some users can contribute higher value but occupy less resources. And the other part of users occupy more resources although contributing less value. Such conventional resource scheduling has not been able to meet the existing network requirements.
In some embodiments of the invention, the non-GBR traffic of a TDD network user comprises a plurality of classes of non-GBR sub-traffic, the classes of non-GBR sub-traffic having different priorities.
Specifically, the non-GBR sub-services may be classified into multiple classes according to the user value of the user and the service type of the non-GBR service.
Wherein, the non-GBR sub-service may include: a certain service of a certain user.
Each type of sub-service comprises: and the services belong to the users with different user priority levels and belong to the services with different service priority levels.
As a specific example, a certain class of non-GBR sub-traffic includes: a portion of the traffic for a user corresponding to user priority 1, the portion of the traffic corresponding to service priority 1. For example, user a and user B each correspond to user priority 1. Service C and service D both correspond to service priority 1. Then, the certain non-GBR sub-service includes: the service system comprises a service C of a user A, a service C of a user B, a service D of the user A and a service D of the user B.
In some embodiments, in order to be able to reasonably classify the non-GBR sub-traffic into multiple classes, the traffic migration method 100 for dealing with the atmospheric waveguide interference further includes S151 to S154:
s151, dividing M user priorities according to the user values of the TDD network users, and setting a first weighted value for each user priority. Wherein M is a positive integer.
In some embodiments, the user value may be determined from the user's subscription data with the mobile operator. For example, it may be a mobile communication service package handled by the user.
As a specific example, an Average Revenue Per User value (ARPU) of a User may be calculated, and the ARPU value represents a profit contributed by each User to a communication carrier. The higher the ARPU value of the user, the greater the user value of the user.
It should be noted that the user value may also be other indexes that can measure the user value in a quantitative manner. Such as the credit rating of the user, the amount of traffic used by the user, the frequency with which the user uses the traffic, the economic status of the user, etc. The user value of the user can be evaluated individually or comprehensively by using the indexes.
For S151, as an example, if the users in the TDD network can be divided into a plurality of user priorities, in order from high to low, the user priorities are 1,User priority 2, … …, user priority M. The first weighted values corresponding to the M priorities are in turn: p is a radical of1,p2,p3,…,pM。
Wherein p is1+p2+…+pM1. Exemplary, p1>p2>…>pM。
S152, dividing N service priorities according to the service types of the non-GBR services, and setting a second weight value for each service priority. Wherein N is a positive integer.
For S152, as an example, if the service type of the non-GBR service in the TDD network can be divided into a plurality of service priorities, in order from high to low, the service priority is 1, the service priority is 2, … …, and the service priority is N. The second weighted values corresponding to the M priorities are in turn: q. q.s1,q2,q3,…,qN。
Wherein q is1+q2+…+qN1. Exemplary, p1>p2>…>pN。
In some embodiments, the priority of non-GBR traffic in the TDD network corresponding to the TDD cell may be determined according to the characteristics of the scenario in which the TDD cell is located.
In some embodiments, the non-GBR traffic may be divided into non-GBR data traffic, non-GBR voice traffic, and non-GBR video traffic.
In other embodiments, the non-GBR traffic may be divided into online video traffic, web browsing traffic, and instant messaging traffic.
In some embodiments, different priorities may be set for non-GBR traffic of the same traffic type of the TDD cell, depending on the specific scenario in which the TDD cell is located.
In one embodiment, the scene of the TDD cell is determined by the geographical position of the TDD and the characteristics of the coverage area of the TDD network. Such as college TDD cells, rural TDD cells, tourist attraction TDD cells, etc.
When the scenarios of the TDD cells are different, the service behavior preferences of the users of the TDD cells are also different. For example, a rural TDD cell, may prefer non-GBR voice traffic, next non-GBR video traffic, and finally non-GBR data traffic. A college TDD cell may prefer non-GBR data traffic, then non-GBR video traffic, and finally non-GBR voice traffic.
Therefore, the priority of non-GBR traffic of the same type may also be different in different TDD cell scenarios.
For example, in a college TDD cell, in order from high service priority to low service priority, the following are performed in sequence: non-GBR data traffic, non-GBR video traffic, and non-GBR voice traffic.
In some embodiments, if no user of a TDD network uses a certain type of traffic, the non-GBR traffic of the cell has no such traffic. For example, if the remote area is a TDD cell, the non-GBR service may only include: non-GBR voice traffic and non-GBR data traffic.
At this time, it is only necessary to set the priorities and the second weight values of the two types.
It should be further noted that the non-GBR service type in the embodiment of the present invention may also be a service characteristic, and is further refined into more service types.
In some embodiments, different priorities may be set for non-GBR traffic according to the frequency of the non-GBR traffic in the TDD cell, and the usage preference of users in the TDD cell for different types of non-GBR traffic.
And S153, calculating products of the M first weight values and the N second weight values respectively to obtain M multiplied by N third weight values.
As an example, the MxN third weight value, if in the form of a matrix, may be expressed as
Wherein w in the ith row and the jth columnij＝piqj。
S154, the MxN third weight values are sorted from large to small, the MxN third weight values are divided into a plurality of groups according to sorting results, and priority is set for each group.
The priorities of the third weight values in the same group are the same, and the priorities of the groups are sequentially reduced according to the descending order of the values of the third weight values in each group.
In some embodiments, after sorting, the M × N third weight values may be equally divided into multiple groups. For example, after the values are arranged from large to small, the first 10 third weighted values may be selected as the first group, and the 11 th to 20 th weighted values may be selected as the 2 nd, … … th, 91 th to 100 th most 10 th groups.
And the first set is set to the highest priority, the second set is set to the second highest priority, … …, and the tenth set is set to the lowest priority.
Correspondingly, if a third weight value obtained by multiplying the first weight value of the user priority 1 and the second weight value of the service priority 1 is located in the first group, the service a of the user a has the highest priority if the user a corresponds to the user priority 1 and the service a corresponds to the service priority 1.
If the third weight value corresponding to the user priority 5 and the service priority 1 is in the group 3, the service a of the user E has a third priority.
If the third weight value corresponding to the user priority 1 and the service priority 5 is in the group 3, the service E of the user a has the third highest priority.
It should be noted that, through steps S151 to S154, different services of the same user may have different priorities, and the same service of different users may also have different priorities. Different services for different users may have the same priority.
In some embodiments of the present invention, in order to reasonably schedule resources, after dividing non-GBR traffic of the TDD network into multiple sub-traffic with different priorities, the traffic migration method 100 for atmospheric waveguide interference further includes S160:
s160, according to the priority from high to low, setting different Quality of Service Class identifiers (QCI) for a plurality of priorities in sequence.
Wherein, the QCI value of the high priority in any two adjacent priorities is 1 larger than the QCI value of the low priority, and the QCI value of the highest priority is 6.
In some embodiments, if R priorities are set in S154, the QCI value of the ith priority is equal to i +5 in order of priority from high to low. Wherein i is more than or equal to 1 and less than or equal to R.
As a specific example, table 2 shows services of an LTE network according to an embodiment of the present invention.
Through the S160, Non-GBR services concentrated in the same QCI can be separated and divided into R QCI classes, and the higher the QCI class is, the higher the resource scheduling priority is.
In some embodiments of the invention, the network quality of the FDD network may deteriorate after the non-GBR traffic of the TDD network is migrated to the FDD network. In order to ensure the network quality of the FDD network, after S130, the service migration method 100 for dealing with the atmospheric waveguide interference further includes:
s170, judging whether the network quality of the FDD network reaches a preset network quality standard value.
In some embodiments, the network quality score S of the FDD network when no atmospheric waveguide interference occurs may be obtained1. Will S1And a threshold factor
Product of G1As a preset network quality standard value. Wherein the content of the first and second substances,
for example,
can be used forIs an empirical value.
In one embodiment, respective evaluation indexes of multiple types of services can be determined, and the grade of each type of service is calculated according to the evaluation index of each type of service. Weighting and adding the scores of the multiple services to obtain a network quality score S of the FDD network1。
Illustratively, if N types of services are included, the scores of the N types of services are s respectively1、s2、……、sN。
Correspondingly, N service priorities are set, and the weighted values of the N service priorities are q1,q2,q3,…,qN。
The network quality score S for the FDD network1＝s1×q1+s2×q2+s3×q3+…sN×qN。
And S180, if the network quality of the FDD network does not reach the preset quality standard value, sequentially judging whether the network quality of the non-GBR sub-service corresponding to each priority is greater than the preset network quality standard value of the non-GBR sub-service corresponding to each priority according to the sequence from high priority to low priority.
In some embodiments, the evaluation indicators of the network quality of non-GBR traffic of different traffic types are different.
For example, the evaluation index of the online video service may include: video response delay, initial delay and video pause rate.
The evaluation index of the web browsing service may include: page display time delay, page display success rate, page display time length more than 5s, page response success rate and page response time delay.
The evaluation index of the instant communication service can comprise: the method comprises the steps of server side TCP link establishment delay, terminal side TCP link establishment delay, server side data transmission RTT and terminal side data transmission RTT.
In one embodiment, a challenge value and a base value may be set for each evaluation index of the ith type of service.
When the acquisition value x of the evaluation index is better than the challenge value x1 (for example, the time delay is less than or equal to the challenge value, and the success rate is greater than or equal to the challenge value), the score of the evaluation index is 100 points;
when the acquisition value x of the evaluation index is different from the basic value x2 (for example, the time delay is greater than or equal to the challenge value, and the success rate is less than or equal to the challenge value), the score of the index is 1 point;
when the collection value of the evaluation index is between the challenge value and the basic value, the score s of the indexixSatisfies formula (1):
in one embodiment, when calculating the score of the network quality of a certain class of non-GBR sub-services, different index weights can be given to the l indexes contained in the class of sub-services. And taking the weighted score sum of each index as the score s of the network quality of the servicei. Wherein s isiThe calculation formula of (2):
