Description

Technical Field

Background

In the current wireless network technology, in order to alleviate the limitation of Uplink capacity and improve edge performance, an Uplink enhancement scheme, that is, an Uplink Data Compression (UDC) technology, is proposed.

In order to solve the problem that the configuration of the UDC in the prior art cannot guarantee performance balance in various aspects, an embodiment of the present invention provides a method for configuring a UDC, where a UDC configuration parameter of a terminal is determined according to a first UDC recommended parameter of the terminal and/or a second UDC recommended parameter reported by the terminal, which are determined by network statistics information, so that different UDC configuration parameters can be configured for each terminal, and performance balance in various aspects is guaranteed.

Specifically, the UDC configuration method according to an embodiment of the present invention is applied to a base station, and as shown in fig. 2, the method includes:

s210, determining a UDC configuration parameter of the terminal according to a first UDC recommendation parameter of the terminal and/or a second UDC recommendation parameter reported by the terminal, wherein the first UDC recommendation parameter is determined by network statistical information;

Wherein the buffer size may include 2K, 4K, and 8K bytes; the dictionary options include a Session Initiation Protocol (sip) -Session Description Protocol (SDP) option and an operator option.

By adopting the configuration method of the UDC, the base station determines the UDC configuration parameters of the terminal according to the first UDC recommendation parameters determined by the network statistical information and/or the second UDC recommendation parameters reported by the terminal, and based on the configuration method of the UDC, the base station can respectively perform UDC configuration for each terminal, and can meet the balance effects of system performance, terminal power consumption and the like under the condition of ensuring compression performance.

Based on this, in step S210, determining a UDC configuration parameter of the terminal according to a first UDC recommended parameter of the terminal and/or a second UDC recommended parameter reported by the terminal, which are determined by the network statistical information, includes:

in step S220, the sending the UDC configuration parameter to the terminal includes:

Therefore, the base station can determine a UDC recommended parameter (a first UDC recommended parameter) for each terminal according to the network statistical information, and/or determine a UDC configuration parameter corresponding to each terminal according to a second UDC recommended parameter reported by each corresponding terminal, so as to ensure that each terminal performs uplink data transmission according to the UDC configuration parameter configured by the base station, and when performing UDC processing on transmitted uplink data, not only can ensure compression performance, but also can satisfy uniform effects of system performance, terminal power consumption and the like, so as to solve the problem that the configuration of the UDC in the prior art cannot ensure performance balance in all aspects.

According to the configuration method of the UDC according to the embodiment of the present invention, in a first implementation manner, in step S210, the base station determines a UDC configuration parameter of the terminal according to a first UDC recommended parameter of the terminal determined by the network statistical information.

Specifically, in the first embodiment, as shown in fig. 3, a schematic flow diagram of a configuration method of the UDC according to an embodiment of the present invention includes:

s310, a terminal UE reports UDC capability information to a base station, wherein the UDC capability information comprises the capability that the terminal can support UDC compression;

s320, the base station acquires the current network statistical information, determines a first UDC recommended parameter of the terminal according to the UDC capability information reported by the terminal, and determines a UDC configuration parameter configured for the terminal according to the determined first UDC recommended parameter;

in this embodiment, the base station may determine that the first UDC recommendation parameter is an UDC configuration parameter that needs to be configured for the terminal, and in addition, the base station may also determine the UDC configuration parameter of the terminal according to the first UDC recommendation parameter and the UDC capability of the UE;

s330, the base station sends a reconfiguration message to the terminal; wherein, the reconfiguration message includes the UDC configuration parameters configured by the base station for the terminal;

alternatively, the reconfiguration message may be a Radio Resource Control (RRC) message.

S340, the terminal sends the response message of the reconfiguration message to the base station, and the configuration signaling is completed.

After the above-mentioned UDC configuration is completed, when the terminal performs uplink data transmission, the terminal may perform UDC processing on the transmitted data according to the UDC configuration parameter sent by the base station, and the base station decompresses the UDC when receiving the data transmitted by the terminal. The compression processing of the uplink transmission data is utilized to achieve the purposes of increasing the uplink capacity and saving uplink physical resources. Further, when the uplink Data transmission service is finished, the base station releases a Data Radio Bearer (DRB) and the UDC.

In this embodiment of the present invention, optionally, the network statistical information is information used for indicating a current network operating state, where the network statistical information may include a network operating state statistically obtained by the base station side itself, and may also include a network operating state statistically obtained by another network element (e.g., a network manager or a third tool) connected to the base station side.

Optionally, the network statistical information includes service operation information and service capability information. Wherein, the service operation information includes but is not limited to only including: at least one of the number of cell users, cell flow information and physical resource utilization rate; the service capability information includes, but is not limited to, only at least one of base station processing capability information, central processing unit CPU occupancy information, and base station power consumption information.

In one embodiment of the present invention, the base station may comprehensively analyze the obtained network statistical information to determine a UDC recommendation parameter (a first UDC recommendation parameter) for each terminal, respectively, on the principle of ensuring performance balance in various aspects.

In one implementation manner of the embodiment of the present invention, optionally, the method further includes:

In this embodiment, optionally, the first UDC evaluation function includes a first UDC preliminary recommendation parameter determined based on the service operation information and a second UDC preliminary recommendation parameter determined based on the service capability information;

By adopting the above embodiment, the first UDC evaluation function is formed by using the service operation information, the evaluation result recommended by the UDC is obtained according to the first UDC evaluation function, and based on the evaluation result, the corresponding UDC configuration parameters can be configured for each terminal respectively.

For example, the first UDC evaluation function may be represented as Z (B (x), D (y)), B (x) represents a first UDC preliminary recommendation parameter determined based on the service operation information, D (y) represents a second UDC preliminary recommendation parameter determined based on the service capability information, D (y) is a constraint condition of B (x), and D (y) further serves as a constraint condition for determining a final value size of the first UDC evaluation function Z (B (x), D (y)) according to B (x) based on determining B (x) by the service operation information, that is, giving a preliminary parameter recommendation.

Alternatively, in one embodiment, the value of Z (B (x), D (y)) may be directly expressed as the value of the first UDC recommended parameter; in another embodiment, the value of Z (B (x), D (y)) may be only a representative value of the first UDC recommended parameter, wherein different representative values correspond to different first UDC recommended parameters.

Alternatively, when B (x) satisfies the condition of D (y), the value determined by Z (B (x), D (y)) is recommended as the value of B (x) that can make the compression performance more excellent.

For example, the UDC configuration parameter includes a buffer size, and the determined Z (B (x), D (y)) is a larger value of the buffer size in B (x) since the larger the value of the buffer size, the better the same data compression effect.

For example, taking the example that performing the UDC configuration includes configuring the buffer size, determining the first UDC preliminary recommendation parameter based on B (x) may be implemented as follows:

the service operation information includes a cell user number, cell traffic information, and/or a physical resource utilization rate, and when based on a cell user number condition, a cell traffic condition, or a physical resource application condition, in one embodiment, the mode of determining B (x) is as follows:

when the number of cell users, the cell flow or the physical resource utilization rate is greater than or equal to a first preset value, determining that the numerical value of the buffer size in B (x) is smaller (for example, the numerical value is a first value); when the number of cell users, the cell flow or the physical resource utilization rate is less than or equal to a second preset value, determining that the numerical value of the buffer size in B (x) is larger (for example, the numerical value is a second value); wherein the first preset value is larger than the second preset value; and when the number of cell users, the cell flow or the physical resource utilization rate is between a first preset value and a second preset value, determining that the numerical value of the buffer size in B (x) is between a first value and a second value.

In another embodiment, the method for determining B (x) may be:

and sorting the numerical values of the buffer sizes which can be applied by the terminal, and respectively setting intervals corresponding to the number of cell users, the cell flow or the physical resource utilization rate which can be applied for each numerical value of the buffer size. On the basis, according to the number of the current counted cell users, the cell flow or the value of the physical resource utilization rate, the corresponding values of the buffer size are respectively determined, namely B (x) is given, and the first UDC preliminary recommendation parameters are determined.

The determination method based on B (x) described above includes, for example:

when the number of cell users is less than or equal to X1, or the cell uplink flow is less than or equal to Y1, or the utilization rate of a cell uplink Physical Resource Block (PRB) is less than or equal to Z1, selecting the value of the configuration buffer size to be 8K, that is, the first UDC preliminary recommendation parameter includes 8K;

when the number of users in a cell is greater than or equal to X2, or the uplink flow of the cell is greater than or equal to Y2, or the uplink PRB utilization rate of the cell is greater than or equal to Z2, selecting the value of the configuration buffer size to be 2K, namely the first UDC preliminary recommendation parameter comprises 2K;

when the number of cell users is between X1 and X2, or the uplink traffic of the cell is between Y1 and Y2, or the uplink PRB utilization of the cell is between Z1 and Z2, the value of the configured buffer size is selected to be 4K, that is, the first UDC preliminary recommendation parameter includes 4K.

It should be noted that the first UDC preliminary recommendation parameter determined in the above manner is an optimal parameter recommended by the base station, and the first UDC preliminary recommendation parameter is not limited to only being able to include the recommended optimal parameter, and may also include other parameters that are lower than the optimal parameter and that can be adopted. For example, when the first UDC preliminary recommendation parameter includes a buffer size of 8K, other buffer sizes smaller than 8K may be included.

In addition, based on the first UDC preliminary recommendation parameter B (x) determined in the above manner, the size of the final first UDC recommendation parameter Z (B (x), D (y)) is determined further with D (y) as a constraint condition of B (x).

And D (y) is determined based on the service capability information, wherein the service capability information comprises at least one of base station processing capability information, central Processing Unit (CPU) occupation information and base station power consumption information. The specific determination method may be:

determining the size of a final first UDC recommended parameter according to a first UDC preliminary recommended parameter B (x) by taking the processing capacity of a base station, such as the size of a total cache, as a limiting condition;

different D (y) recommendations are given according to the running condition of the base station, for example, the CPU runs in different percentage conditions, for example, the CPU occupation is low, the recommended D (y) can use larger cache size, the CPU occupation is high, and the recommended D (y) can use smaller cache size; determining the size of the final first UDC recommended parameter by taking the D (y) as the limiting condition of the first UDC preliminary recommended parameter B (x);

and determining the size of the final first UDC recommended parameter and the like by using the power consumption condition of the base station, such as whether the base station is overheated or not, and recommending a smaller buffer size if the base station is overheated as a limiting condition of the first UDC preliminary recommended parameter B (x).

For example, the rule for determining the first UDC preliminary recommendation parameter B (x) is as follows: if the number of users is larger than a certain threshold value, configuring a smaller buffer size, such as a parameter of 2K Bytes; if the number of users is smaller than a certain threshold value, a larger buffer size is configured, for example, a parameter of 8K Bytes, and a parameter of 4K Bytes is configured when the buffer size is between the two parameters.

And when the base station determines that the number of the users is between the two threshold values according to the number of the users in the cell counted in the current period of time and the configuration cache size of the first UDC preliminary recommendation parameter B (x) to be determined is a parameter of 4Kbytes, further taking the current CPU occupation condition as a constraint condition to limit the finally determined cache size. If the CPU occupation situation is determined to be larger than a preset threshold, and the cache size needing to be configured is smaller than or equal to 4K, determining that the first UDC preliminary recommendation parameter B (x) is 4K Bytes and meets the condition according to the limiting condition, and selecting the optimal value of the 4K Bytes as a final first UDC recommendation parameter; and if the CPU occupation condition is determined to be larger than the preset threshold and the cache size needing to be configured is smaller than 4K, determining that the first UDC preliminary recommendation parameter B (x) is smaller than 4K and meets the condition according to the limiting condition, and selecting the cache size of 2K as the final first UDC recommendation parameter.

It can be understood that, the above-mentioned determination condition using the number of cell users as the first UDC recommendation parameter may also be replaced by a cell traffic or a physical resource utilization rate, for example, a PRB utilization rate.

The cell user number may be an RRC connection user number counted in a period of time or an RRC effective connection user number, and the cell traffic may be cell uplink traffic. In addition, the number of users in the cell, the cell flow and/or the physical resource utilization rate can be counted by the base station, and can also be obtained from the network manager.

It is to be understood that, the above description is made by taking the example that the UDC configuration parameter includes the buffer size, and when the UDC configuration parameter includes other values, such as including the dictionary option, the configuration manner of the dictionary option may also be determined by using the above criteria, and will not be described in detail here.

It should be further noted that, by using the method for configuring a UDC according to the foregoing embodiment of the present invention, the first UDC recommended parameter determined according to the network statistical information may be a first UDC recommended parameter applicable to each terminal in a cell. Optionally, in this embodiment, when the base station only needs to determine the UDC configuration parameter of the terminal according to the first UDC recommendation parameter, the base station may determine the UDC configuration parameter of each terminal according to the determined first UDC recommendation parameter and according to the UDC capability of each terminal.

According to the method for configuring the UDC in the embodiment of the present invention, in the second embodiment, in step S210, the base station determines the UDC configuration parameter of the terminal according to the second UDC recommended parameter reported by the terminal.

Based on this, before step S210, the method further includes:

Specifically, in the second embodiment, as shown in fig. 4, the flowchart of the configuration method of the UDC according to the embodiment of the present invention includes:

s410, a terminal UE reports UDC capability information to a base station, wherein the UDC capability information comprises the capability that the terminal can support UDC compression;

s420, reporting the UDC recommended parameter reporting information to the base station by the UE, wherein the UDC recommended parameter reporting information comprises a second UDC recommended parameter;

s430, the base station determines the UDC configuration parameters of the terminal according to the second UDC recommended parameters reported by the UE;

s440, the base station sends a reconfiguration message to the terminal; wherein, the reconfiguration message includes the UDC configuration parameters configured by the base station for the terminal;

S450, the terminal sends the response message of the reconfiguration message to the base station, and the configuration signaling is completed.

After the above-mentioned UDC configuration is completed, when the terminal performs uplink data transmission, the terminal may perform UDC processing on the transmitted data according to the UDC configuration parameter sent by the base station, and the base station decompresses the UDC when receiving the data transmitted by the terminal. The compression processing of the uplink transmission data is utilized to achieve the purposes of increasing the uplink capacity and saving uplink physical resources. Further, when the uplink data transmission service is finished, the base station releases the data radio bearer DRB and the UDC.

Optionally, in step S420, a preset bit in the report information of the UDC recommended parameter is used to represent the second UDC recommended parameter.

For example, 3 UDCs of the 3gpp Release 15 are cached, and the preset bit may be 2 bits and is used to indicate a second UDC recommended parameter; wherein 2bit can represent 4 types of second UDC recommendation parameters, 3 of them are selected to represent the second UDC recommendation parameters, for example, 00 represents that the second UDC recommendation parameter is 2K byte,01 represents that the second UDC recommendation parameter is 4K byte,10 represents that the second UDC recommendation parameter is 8K byte, and 11 can be reserved.

For the 5G NR system, since there may be more types of supported buffer sizes, in the report information of the UDC recommendation parameter, a preset bit capable of correspondingly representing each buffer size may be used to represent a value of the buffer size recommended by the second UDC recommendation parameter. In one embodiment of the present invention, the terminal may comprehensively analyze current terminal service information based on its service characteristics, for example, analyze current terminal processing capability, operation condition, and/or power consumption condition, and determine the second UDC recommendation parameter reported to the base station.

In another implementation manner of the embodiment of the present invention, the terminal may generate the UDC evaluation function according to the terminal service information within the preset time duration, and determine the second UDC recommendation parameter reported to the base station according to the UDC evaluation function.

Based on this, optionally, before the terminal reports the UDC recommendation parameter reporting information to the base station, the method further includes:

Optionally, the terminal service information includes terminal service operation information and terminal capability information;

By adopting the embodiment, the terminal forms the second UDC evaluation function by utilizing the terminal service information, and obtains the recommended second UDC recommendation parameters according to the second UDC evaluation function, so that the UDC recommendation parameters recommended by the terminal can be reported to the base station.

Optionally, the terminal service information includes terminal service operation information and terminal capability information, the terminal service operation information may include, for example, service processing capabilities of different services and/or duty conditions of different service executions, and the terminal capability information includes UDC capabilities, CPU operation conditions and/or terminal power consumption conditions.

For example, the second UDC evaluation function may be represented as F (p (x), q (y)), where p (x) represents a third UDC preliminary recommendation parameter determined based on the terminal service operation information, q (y) represents a fourth UDC preliminary recommendation parameter determined based on the terminal capability information, and q (y) is a constraint condition of p (x), and q (y) further serves as a constraint condition for determining a final value size of the second UDC evaluation function F (p (x), q (y)) according to p (x) on the basis of determining p (x) by using the terminal service operation information, that is, giving a preliminary parameter recommendation.

Alternatively, in one embodiment, the value of F (p (x), q (y)) may be directly expressed as the value of the second UDC recommended parameter; in another embodiment, the value of F (p (x), q (y)) may be only a representative value of the second UDC recommendation parameter, wherein different representative values correspond to different second UDC recommendation parameters.

Alternatively, when p (x) satisfies the condition of q (y), the value determined by F (p (x), q (y)) is recommended as the value of p (x) that can make the compression performance more excellent.

For example, taking the example that performing the UDC configuration includes configuring the buffer size, determining the third UDC preliminary recommendation parameter based on p (x) may be implemented as follows:

in one embodiment, the terminal service operation information includes ratio information of different services, and the terminal can preferentially configure a higher buffer size for some services by counting different service ratios of users within a period of time. For example, if the traffic occupancy of the Voice over Long-Term Evolution (VOLTE) and the downlink video (corresponding to the uplink being the feedback of the uplink) of the user is higher than a certain threshold, the buffer size (the third UDC preliminary recommendation parameter) configured for the user is 8k, or a corresponding buffer size may be configured according to the occupancy interval of the service; wherein the configured buffer sizes are different when the occupation intervals are different.

It should be noted that the third UDC preliminary recommendation parameter determined in the above manner is an optimal parameter recommended by the base station, and the third UDC preliminary recommendation parameter is not limited to only being able to include the recommended optimal parameter, and may also include other parameters that are lower than the optimal parameter and that can be adopted. For example, when the third UDC preliminary recommendation parameter includes a buffer size of 8K, other buffer sizes smaller than 8K may be included.

In addition, based on the third UDC preliminary recommendation parameter p (x) determined in the above manner, the size of the final second UDC evaluation function F (p (x), q (y)) is further determined with q (y) as a constraint condition of p (x).

Wherein q (y) is determined by terminal capability information, and the terminal capability information comprises UDC capability, CPU operation condition and/or terminal power consumption. The specific determination method may be:

with the processing capability of the terminal, for example, the UDC capability as a limiting condition, if the buffer size that the terminal can only support is 2K, that is, the buffer size determined according to q (y) is 2K, then in the case where the optimal buffer size of p (x) is determined according to the above manner, no matter what the value is, the buffer size that the second UDC evaluation function F (p (x), q (y)) can only recommend is 2K; that is, the recommended buffer size of the second UDC recommendation parameter is 2K;

taking the running condition of the CPU as a limiting condition, wherein when the CPU runs in different percentage conditions, different q (y) recommendations can be correspondingly given, for example, the CPU occupation is low, the recommended q (y) can use a larger buffer size, the CPU occupation is high, and the recommended q (y) can use a smaller buffer size; on the basis, the value determined by the second UDC evaluation function F (p (x), q (y)) is a value determined by a constraint condition taking q (y) as p (x);

similarly, the terminal power consumption situation is taken as a limiting condition, for example, whether the terminal is overheated or not can correspond to different q (y) recommendations, and if the terminal is overheated, the recommended q (y) can use a smaller buffer size. On this basis, the second UDC evaluation function F (p (x), q (y)) is determined as a value determined by a constraint condition with q (y) as p (x).

Based on the foregoing embodiment, because different buffer sizes have different compression efficiencies for different services, based on the second UDC recommended parameters with different values reported by the terminal, the terminal can accurately determine the UDC configuration parameter of each terminal, so that different terminals, bearers, or different Quality of Service (QoS) level identifiers (5G is 5 QI) in one cell can execute different compression efficiencies by using different UDC configuration parameters, so as to ensure performance balance in various aspects of the system.

In this embodiment of the present invention, optionally, in step S210, the determined UDC configuration parameter may be configured by the terminal, or may be configured according to a bearer of the terminal. For example, in one embodiment, the determined UDC configuration parameter may be configured for the entire terminal, that is, the UDC configuration parameter is applicable to any service or bearer of the terminal; in another embodiment, the determined UDC configuration parameter is only applicable to one of the services or bearers of the terminal, and different services or bearers may configure different UDC configuration parameters. For example, an 8K buffer size may be configured for the volte bearer, and other services or bearers may be configured with different buffer sizes according to the above method. For example, bearers may also be distinguished according to QCI or 5 QI.

According to the configuration method of the UDC according to the embodiment of the present invention, in the third embodiment, in step S210, the base station determines the UDC configuration parameter of the terminal according to the first UDC recommended parameter of the terminal determined by the network statistical information and the second UDC recommended parameter terminal reported by the terminal.

Specifically, the base station may determine the UDC configuration parameter according to the first UDC recommended parameter and the second UDC recommended parameter, in accordance with performance requirements of various aspects of the system.

Optionally, in an embodiment, the base station may determine the UDC configuration parameter of each terminal by combining the first UDC recommended parameter and the second UDC recommended parameter respectively determined in the foregoing manner. For example, firstly, according to a first UDC recommended parameter, a cell-level UDC configuration parameter is determined, and then, according to a second UDC recommended parameter, a UDC configuration parameter configured for one of users or one of bearers in a cell is determined. That is, the cells are classified or grouped by using the above method for determining the first UDC recommended parameter, and different cells configure different UDC configuration parameters; and then classifying or grouping a plurality of users or terminals in the cell by using the second UDC recommended parameters respectively reported by the plurality of terminals in the cell, and configuring different UDC configuration parameters for different users, terminals or different bearers.

Therefore, in this embodiment of the present invention, determining, by a base station, a UDC configuration parameter corresponding to each of at least two terminals according to a first UDC recommended parameter corresponding to each of the at least two terminals and a second UDC recommended parameter reported by each of the at least two terminals includes:

and respectively determining the UDC configuration parameters of each terminal according to the first UDC recommendation parameters in the same group and the second UDC recommendation parameters corresponding to each terminal of the cell in the same group.
