The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the invention.

It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any relationship between these entities or operations. any such actual relationship or sequence exists. Moreover, the terms "comprising", "comprising" or any other variation thereof are intended to encompass a non-exclusive inclusion such that a process, method, article or device that includes a list of elements includes not only those elements, but also includes not explicitly listed or other elements inherent to such a process, method, article or apparatus.

According to different duplex communication modes used, existing cells can be divided into FDD cells using Frequency Division Duplexing (FDD) technology and TDD cells using TDD technology. The FDD cell covers the FDD network, and the TDD cell covers the TDD network.

In practice, the FDD network and the TDD network will cover the same area at the same time. Users in this area are connected to the FDD network or the TDD network. Specifically, if a user is connected to an FDD network, the user may be referred to as an FDD network user. If a user connects to a TDD network, the user may be referred to as a TDD network user.

However, when the TDD network is disturbed by atmospheric fluctuations, the services of TDD network users will be greatly affected.

Therefore, there is a need for a method, device, equipment and medium that can effectively deal with atmospheric waveguide interference

For better understanding of the present invention, the following will describe in detail the method, device, device and medium for service migration for coping with atmospheric waveguide interference according to embodiments of the present invention with reference to the accompanying drawings. It should be noted that these embodiments are not used to limit the disclosure of the present invention. range.

FIG. 1 is a schematic flowchart illustrating a service migration method for coping with atmospheric waveguide interference according to an embodiment of the present invention. As shown in FIG. 1 , the service migration method 100 for coping with atmospheric waveguide interference in this embodiment may include the following steps S120 and S130:

S120, it is determined 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 atmospheric waveguide interference, before S120, the service migration method 100 for dealing with atmospheric waveguide interference further includes:

S111: Acquire the interference signal strength of a physical broadcast channel (Physical Broadcast Channel, PBCH) allocated by the synchronization signal in the TDD network.

The synchronization signals in S111 include: a primary synchronization signal (Primary Synchronization Signal, PSS) and a secondary synchronization signal (Secondary Synchronization Signal, SSS).

In some embodiments, the SSS signal and the PSS signal occupy the middle 6 physical resource blocks (Physical Resource Block, PRB) in the frequency domain of the TDD network.

As an example, the TDD network may use a 20 MHz co-frequency network. In the frequency domain, a Long Term Evolution (Long Term Evolution, LTE) signal is formed by combining hundreds of sub-carriers, and the bandwidth of each sub-carrier is 15 kHz. That is, a bandwidth of 20 MHz contains 1200 subcarriers. The physical resources of LTE can be defined from two dimensions of time and frequency. In the frequency domain, each physical resource block is composed of 12 consecutive subcarriers, which are 1 PRB. Accordingly, a bandwidth of 20 MHz contains 100 PRBs.

When the interference signal strength of the 46th PRB to the 52nd PRB on the TDD network is observed to be constantly interfered, and the strength of the interference signal is significantly higher than that of the remaining 94 PRBs, it is determined that the TDD network is interfered by atmospheric waveguides.

In some embodiments, the specific implementation of S111 may include: monitoring and counting the interference level of the TDD network. For example, the interference level of each PRB in the TDD network 100 PRB is monitored.

S112: Determine whether the interference signal strength exceeds a preset interference signal strength threshold.

In some embodiments, the interference signal strength threshold may be preset according to the characteristics of the TDD network when the atmospheric waveguide interferes.

As a specific example, the value of the interference signal strength threshold may be -110dB.

It should be noted that, if after S112, the interference signal strength of the PBCH corresponding to the synchronization signal does not exceed the preset interference strength threshold, it is considered that the current TDD network suffers from conventional interference, and the processing is performed according to the processing method for conventional interference.

S113, if the interference signal strength exceeds a preset interference signal strength threshold, it is determined that the TDD network corresponding to the current area is interfered by the atmospheric waveguide.

In some embodiments, it may be determined whether the interference signal strengths of the PBCH corresponding to the synchronization signal all exceed a preset interference signal strength threshold. If both exceed the preset interference signal strength threshold, it is determined that the TDD network covering the current area is interfered by atmospheric waveguides.

As a specific example, when the measured interference signal strengths of the 6 PRBs corresponding to the synchronization signal are higher than the preset interference signal strength threshold, it is determined that the TDD network covering the current area is interfered by atmospheric waveguides.

S130: Migrate the non-GBR service of the TDD network user in the current area to the FDD network covering the current area.

The TDD network user refers to a user connected to the TDD network.

According to the service migration method, device, device and medium for coping with atmospheric wave guide interference in the embodiments of the present invention, when it is determined that the TDD network is interfered by atmospheric fluctuations, the non-GBR service of the TDD network user can be migrated to the FDD network. Since the FDD network can avoid atmospheric interference, the non-GBR service of the TDD network users is migrated to the FDD network, which can improve the ability to cope with the atmospheric waveguide service.

In some embodiments of the present invention, the specific manner of migrating the non-GBR service to the FDD network may be: migrating the non-GBR service to the FDD network by means of cell handover or cell reselection.

Specifically, under normal circumstances, the reselection priority and the handover priority of the TDD network are higher than those of the FDD. Users in the current area preferentially reside on the TDD network.

When the TDD network covering the current area is disturbed by atmospheric fluctuations, the handover priority and/or reselection priority of the FDD network covering the current area can be increased, and the improved handover priority and/or reselection priority of the FDD network is high On the TDD network, users in the current area can preferentially reside on the FDD network.

It should be noted that, in this embodiment of the present invention, after it is determined that the TDD network is subjected to atmospheric waveguides, in addition to performing S130, the power of the TDD network may also 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 original service in the TDD network is not affected by atmospheric fluctuation interference, after S120, the service migration method 100 for coping with atmospheric waveguide interference further includes:

S140: Switch the guaranteed bit rate (Guranteed Bit Rate, GBR) service using the TDD network in the current area to the FDD network.

The QCI value of the GBR service is less than 5.

In some embodiments of the present invention, the migration mode of the GBR service is the same as that of the non-GBR service.

Among them, since the GBR service has high requirements for implementation, the migration mode of the GBR service is preferably cell handover.

In some embodiments of the present invention, Table 1 shows the services of the existing LTE network. QCI is a parameter used by the system to identify the transmission characteristics of service data packets. Among them, the GBR service represents a service that requires high real-time performance, and a minimum bit rate needs to be guaranteed for this type of service. Non-GBR services do not require high real-time performance, and there is no need to guarantee the minimum bit rate for such services.

A total of 5 QCI values are currently deployed on the live network, among which the QCI values of the GBR service are 1 to 3.

Among them, the VoLTE video of the GBR service is different from the streaming video of the non-GBR service. VoLTE video represents a video call based on VoLTE network, and streaming video includes services such as watching and downloading online video.

It should be noted that, according to the allocation method in Table 1, the vast majority of users and services are currently concentrated on the same QCI, that is, share the same resource. Due to the differentiation of business types and user types, some users may contribute higher value but occupy less resources. On the other hand, although the value contributed by other users is lower, they take up more resources. This traditional resource scheduling can no longer meet the needs of the existing network.

In some embodiments of the present invention, the non-GBR service of the TDD network user includes multiple types of non-GBR sub-services, and the multiple types of non-GBR sub-services have different priorities.

Specifically, it can be divided into multiple types of non-GBR sub-services according to the user value of the user and the service type of the non-GBR service.

Among them, the non-GBR sub-service may include: a certain service of a certain user.

Each type of sub-service includes: services belonging to users of different user priority levels and services belonging to different service priorities.

As a specific example, a certain type of non-GBR sub-service includes: a part of the service of the user corresponding to the user priority 1, and the part of the service corresponds to the service priority 1. For example, User A and User B both correspond to User Priority 1. Both service C and service D correspond to service priority 1. The above-mentioned certain type of non-GBR sub-services include: C service of user A, C service of user B, D service of user A, and D service of user B.

In some embodiments, in order to be reasonably divided into multiple types of non-GBR sub-services, the service migration method 100 for coping with atmospheric waveguide interference further includes S151 to S154:

S151: Divide M user priorities according to user values of TDD network users, and set a first weight value for each user priority. Among them, M is a positive integer.

In some embodiments, the user value may be determined based on subscription data between the user and the mobile operator. For example, it may be a mobile communication service package handled by the user.

As a specific example, the average revenue per user (Average Revenue PerUser, ARPU) of the user can be calculated, and the ARPU value represents the profit contributed by each user to the communication operator. The higher the ARPU value of the user, the greater the user value of the user.

It should be noted that the user value can also be other indicators that can quantify the user value. For example, the credit level of the user, the amount of business used by the user, the frequency of the user using the business, the economic status of the user, and the like. The user value of the user can be evaluated individually or comprehensively by using the above indicators.

For S151, as an example, if users in the TDD network can be divided into multiple user priorities, in descending order, they are user priority 1, user priority 2, ..., user priority M. The first weight values corresponding to the above M priorities are: p ₁ , p ₂ , p ₃ , . . . , p _M .

where, p ₁ +p ₂ +...+p _M =1. Exemplarily, p ₁ >p ₂ >...>p _M .

S152: Divide N service priorities according to the service type of the non-GBR service, and set a second weight value for each service priority. Among them, 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 multiple service priorities, in order from high to low, they are service priority 1, service priority 2, ..., Business priority N. The second weight values corresponding to the above M priorities are: q ₁ , q ₂ , q ₃ , . . . , q _N .

where q ₁ +q ₂ +...+q _N =1. Exemplarily, p ₁ >p ₂ >...>p _N .

In some embodiments, the priority of the non-GBR service in the TDD network corresponding to the TDD cell may be determined according to the characteristics of the scene where the TDD cell is located.

In some embodiments, non-GBR services can be divided into non-GBR data services, non-GBR voice services, and non-GBR video services.

In other embodiments, non-GBR services can be divided into online video services, web browsing services and instant messaging services.

In some embodiments, different priorities may be set for non-GBR services of the same service type in the TDD cell according to the specific scenario in which the TDD cell is located.

In one embodiment, the scene where the TDD cell is located is determined by the geographical location where the TDD is located and the characteristics of the coverage area of the TDD network. For example, college TDD community, rural TDD community, tourist attraction TDD community, etc.

When the scenarios in which the TDD cells are located are different, the service behavior preferences of the users of the TDD cells are also different. For example, in a rural TDD cell, non-GBR voice services may be most preferred, followed by non-GBR video services, and finally non-GBR data services. In university TDD communities, non-GBR data services may be the most preferred, followed by non-GBR video services, and finally non-GBR voice services.

Therefore, in different TDD cell scenarios, the priorities of the same type of non-GBR services may also be different.

For example, in a university TDD community, in order of service priority from high to low, the order is: non-GBR data service, non-GBR video service, and non-GBR voice service.

In some embodiments, if none of the users of a certain TDD network use a certain type of service, the non-GBR service of the cell does not have this type of service. Exemplarily, in the case of a TDD cell in a remote area, the non-GBR service may only include: non-GBR voice service and non-GBR data service.

At this time, it is only necessary to set the priority and the second weight value of the above two categories.

It should also be noted that, the non-GBR service types in the embodiments of the present invention can also be further refined into more service types based on service characteristics.

In some embodiments, the settings for the non-GBR service may be set according to factors such as the frequency of use of the service type of the non-GBR service in the TDD cell, and the preference of users in the TDD cell for the service types of different types of non-GBR services. different priorities.

S153: Calculate the product of the M first weight values and the N second weight values respectively, to obtain M×N third weight values.

其中，第i行第j列的w_ij＝p_iq_j。As an example, if the M×N third weight value is in the form of a matrix, it can be expressed as

Wherein, w _ij = p _i q _j in the i-th row and the j-th column.

S154 , sort the M×N third weight values in descending order, divide the M×N third weight values into multiple groups according to the sorting result, and set a priority for each group.

The priorities of the third weight values in the same group are the same, and the priorities of the third weight values in each group decrease in descending order among multiple groups.

In some embodiments, after sorting, the M×N third weight values may be divided into multiple groups equally. For example, a total of 100 third weight values, arranged in descending order of value, can be selected as the first 10 as the first group, the 11th to 20th as the second group, ..., the 91st to the 20th. The 100th is the 10th group.

And set the first group as the highest priority, the second group as the second highest priority, ..., the tenth group as the lowest priority.

Correspondingly, if the third weight value obtained by multiplying the first weight value of user priority 1 and the second weight value of service priority 1 is in the first group, if user A corresponds to user priority 1, the service A corresponds to service priority 1, and user A's service A has the highest priority.

If the third weight values corresponding to the user priority 5 and the service priority 1 are located in the third group, the service A of the user E has the third priority.

If the third weight values corresponding to the user priority 1 and the service priority 5 are in the third group, 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 services of different users may also have different priorities. Different services of different users may have the same priority.

In some embodiments of the present invention, in order to reasonably schedule resources, after the non-GBR service of the TDD network is divided into multiple types of sub-services with different priorities, the service migration method 100 for atmospheric waveguide interference further includes S160:

S160, according to the priority from high to low, set different quality of service class identifiers (Quality of Service Class Identifier, QCI) for multiple priorities in sequence.

Wherein, the QCI value of the high priority in any two adjacent priorities is 1 greater 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 according to the order of priority from high to low. Among them, 1≤i≤R.

As a specific example, Table 2 shows the services of the LTE network according to the embodiment of the present invention.

Through S160, the Non-GBR services concentrated in the same QCI can be separated and divided into R QCI levels. The higher the QCI level, the higher the resource scheduling priority.

In some embodiments of the present invention, after migrating the non-GBR services of the TDD network to the FDD network, the network quality of the FDD network may be degraded. In order to ensure the network quality of the FDD network, after S130, the service migration method 100 for coping with atmospheric waveguide interference further includes:

S170: Determine whether the network quality of the FDD network reaches a preset network quality standard value.

的乘积G₁作为预设网络质量标准值。其中，

例如，

可以是一个经验值。In some embodiments, the network quality score S ₁ of the FDD network may be obtained when no atmospheric waveguide interference occurs. Combining _S1 with the threshold factor

The product of G ₁ is taken as the preset network quality standard value. in,

E.g,

Can be an experience value.

In one embodiment, the respective evaluation indicators of multiple types of services may be determined, and according to the evaluation indicators of each type of service, the score of this type of service may be calculated. The network quality score S ₁ of the FDD network is obtained after the scores of the multiple types of services are weighted and added.

Exemplarily, if N types of services are included, the scores of the N types of services are respectively s ₁ , s ₂ , ..., s _N .

Correspondingly, N service priorities are set, and the weight values of the N service priorities are respectively, q ₁ , q ₂ , q ₃ , . . . , q _N .

Then the network quality score of the FDD network S ₁ =s ₁ ×q ₁ +s ₂ ×q ₂ +s ₃ ×q ₃ +...s _N ×q _N .

S180, if the network quality of the FDD network does not reach the preset quality standard value, according to the order of priority from high to low, determine whether the network quality of the non-GBR sub-service corresponding to each priority is greater than the preset priority. The network quality standard value of the corresponding non-GBR sub-service.

In some embodiments, the evaluation indexes of the network quality of non-GBR services of different service types are different.

For example, the evaluation index of the online video service may include: video response delay, initial delay delay, and video freeze rate.

The evaluation indicators of the web browsing service may include: page display delay, page display success rate, percentage of page display duration of more than 5s, page response success rate, and page response delay.

The evaluation indicators of the instant messaging service may include: the delay of establishing a link on the server side TCP, the delay in establishing a link on the terminal side TCP, the data transmission RTT on the server side, and the data transmission RTT on the terminal side.

In one embodiment, for each evaluation index of the i-th service, a challenge value and a basic value may be set.

When the collection value x of this evaluation index is better than the challenge value x1 (for example, the 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 this evaluation index is 100 points;

When the collection value x of this evaluation index is worse than the basic value x2 (for example, the 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 this index is 1 point;

When the collected value of this evaluation index is between the challenge value and the base value, the score s _ix of this index satisfies formula (1):

In an embodiment, when calculating the network quality score of a certain type of non-GBR sub-service, different index weights may be assigned to the indicators included in this type of sub-service. The sum of the weighted scores of each index is taken as the score _si of the network quality of this type of service. The calculation formula of _si is formula (2):

Among them, s _j represents the score of the j-th indicator, and αj represents the index weight value of the j-th indicator. Exemplarily, α1+...+α1=1.

In some embodiments, when calculating the network quality of the non-GBR sub-service corresponding to each priority, the calculation may be performed according to the proportion of each type of service in the non-GBR sub-service corresponding to each priority. If the i-th priority includes N types of services, the proportions are respectively a%, b%, ..., n%. Among them, a%+b%+...+n%=1. The scores of N-type services are respectively s ₁ , s ₂ , ..., s _N . Then the network quality score _Gi =s ₁ ×a%+s ₂ ×b%+...+s _N ×n% corresponding to the priority.

S190: Determine that the network quality of the sub-service corresponding to a certain priority is not greater than the preset network quality standard value of the sub-service corresponding to the priority, and migrate the sub-services corresponding to all priorities not higher than the priority to migration Back to TDD network.

In some embodiments, in the order of priority from high to low, starting from the highest priority, it is possible to confirm whether the network quality of the sub-service of each priority is greater than the preset network quality of the sub-service corresponding to the priority. standard value. If it is greater than that, continue to confirm whether the next level is greater than the preset network quality standard value of the sub-service corresponding to the next priority level. If it is greater than that, execute S190.

As an example, if a total of 10 priorities are included, in order from high to low, the network quality scores corresponding to the first seven priorities are all greater than the preset network quality standard values of the sub-services corresponding to the corresponding priorities. The network quality score G8 corresponding to the _8th priority is not greater than the network quality standard value of the sub-service corresponding to the 8th priority.
