Description

Technical Field

[0001] The present invention relates to the field of multi-scale allocation of carrier dual-mode communication resources, and in particular to a device and method for multi-scale allocation of HPLC carrier dual-mode communication resources. Background Art

[0002] The development of smart grids and the construction of new power systems have led to a surge in the number of electricity market users, and the number of electricity services has increased accordingly. Different electricity services have different communication resource requirements. At the same time, in addition to regular services, there are a large number of emergency services that may occupy communication resources. HPLC dual-mode communication refers to the use of high-speed power line carrier communication HPLC (High-speed Power Line Communications) and high-speed wireless communication technology HRF (High-speed Radio Frequency) for data transmission, realizing dual-channel, two-way, high-speed, and stable transmission of data on power lines, and is widely used in scenarios such as smart power distribution and utilization. Therefore, it is necessary to allocate HPLC carrier dual-mode communication resources, and reasonably allocate and adjust communication resources according to the differentiated communication resource requirements of the services and the occurrence of emergency services. This can efficiently utilize communication resources, meet the differentiated needs of the services, and provide stable and reliable communication resource support for the stable operation of power services.

[0003] The traditional HPLC carrier dual-mode communication resource allocation method is usually optimized in advance based on existing communication resources or business needs, and the communication resource allocation plan is determined based on the optimization results. However, the traditional HPLC carrier dual-mode communication resource allocation method still has the following problems. First, the traditional communication resource allocation method does not take into account the resource redundancy interval of the business, the resource utilization efficiency is low, and it cannot meet the differentiated business needs. Secondly, the existing method only considers the large-scale allocation of communication resources and cannot make real-time adjustments to communication resources on a small time scale, resulting in difficulty in meeting sudden business needs. Therefore, there is an urgent need to design a multi-scale allocation method and device for HPLC carrier dual-mode communication resources to achieve reasonable allocation of communication resources, improve resource utilization efficiency, and meet the differentiated business needs.

[0004] Prior art 1

[0005] Title: A communication resource allocation method based on intelligent reflective surface assistance

[0006] Disadvantages of the prior art 1

[0007] Prior art proposes an IRS-assisted communication resource allocation method. First, a resource allocation model is constructed. Second, constraints are optimized based on communication system parameters to obtain a target resource allocation model. Finally, a target communication resource allocation plan is determined based on the target resource allocation model. However, this method fails to consider the resource redundancy interval of services and fails to rationally allocate communication resources based on this interval. This results in inefficient resource utilization and an inability to meet the differentiated communication resource requirements of services.

[0009] Title: A method for allocating communication resources in the industrial Internet

[0010] Disadvantages of the second prior art

[0011] A second prior art approach proposes a method for allocating communication resources for the Industrial Internet. This method identifies the specific services used by users or terminals, initiates a resource reservation request to an edge server, and allocates communication resources based on the request. However, this method only considers the allocation of communication resources over a large timescale and fails to adjust communication resources in real time over a small timescale, making it difficult to meet sudden service demands.

Second, the business resource redundancy interval and the redundancy interval utility are calculated. Then, the dual-mode communication resource allocation is optimized based on the maximization of the redundancy interval utility of all terminal resources. Next, the probability of emergency business occurrence is updated and the terminal resource deviation is calculated. Finally, the terminal resources are cut and the cut resources are adjusted according to the resource deviation. The details are as follows:

[0060] (1) Large-scale allocation method of dual-mode communication resources based on maximizing the utility of resource redundancy intervals

[0061] Step 1: Based on the terminal's regular business needs, construct the boundary of the feasible domain for communication resource allocation. Without considering the business needs during emergencies, construct the boundary of the feasible domain for communication resource allocation, including single HPLC resource allocation, single wireless allocation, and the minimum amount of resources required to meet the terminal's regular business needs under different HPLC and wireless ratios. Define the large time scale as a period, consider a total of I periods, and represent the set as Define the small scale as a time slot, consider T time slots in total, and the set is expressed as Each T0 time slot constitutes a period, that is, T = IT0. Consider N terminals, the set is expressed as where d n Represents the nth terminal. There are M types of burst services, and the set is represented as where c m Denotes the mth burst service. Define a total of K communication resource allocation situations, the set is expressed as Where k = 1, 2 represent single HPLC resource allocation and single wireless allocation respectively, and k = 3, ..., K represent different HPLC and wireless allocation ratios. For the i-th period based on terminal d n The feasible domain boundary of communication resource allocation for conventional business needs is expressed as the minimum equivalent resource amount that needs to be allocated to meet the conventional business needs of the terminal in the kth communication resource allocation case when the business needs of emergencies are not considered. It is expressed as

[0062]

[0063] Where μ n,0 For terminal d n Regular business delay requirements; a n,0 (i) is the terminal d in the i-th period n The amount of regular business data; τ n,0 For terminal d n Normal business cycle; SINR k is the signal-to-interference-noise ratio of the resource block under the kth communication resource allocation. The formula means that the minimum amount of resources required to meet the terminal's regular service needs is equal to the terminal d n It is directly proportional to the amount of service data, and inversely proportional to the conventional service delay requirement, service cycle, and resource block signal-to-interference-and-noise ratio under different communication resource allocation situations.

[0064] according to The HPLC and wireless communication resource allocation strategy can be obtained, which is expressed as

[0065]

[0066] Where, and They represent the number of packets allocated to terminal d when only regular services are considered in the i-th period. n HPLC resources and wireless resources; k represents the ratio of HPLC to wireless in the kth communication resource allocation case. In particular, ρ 1 =1,ρ 2 =0.

[0067] Step 2: Based on the sudden service demands of different terminals, calculate the corresponding communication resource allocation feasible domain boundary conditions. Definition For the i-th time period, under the k-th communication resource allocation condition, based on the terminal d n Burst business c m The boundary of the feasible region of communication resource allocation required changes, which is expressed as

[0068]

[0069] Where μ n,m For terminal d n Burst business c m Delay requirement; a n,m (i) is the terminal d in the i-th period n Burst business c m The amount of data; τ n,m For terminal d n The sudden business c m business cycle.

[0070] Similarly, the changes in HPLC and wireless communication resource allocation strategies can be obtained, which can be expressed as

[0071]

[0072] Where, ρ k The ratio of HPLC to wireless under different communication resource allocation conditions; For the kth communication resource allocation in the i-th time period, based on d n Burst business c m Changes in the boundaries of the feasible region for communication resource allocation required; and The kth communication resource allocation in the i-th time period is based on d n The sudden business c m HPLC of demand and changes in wireless communication resource allocation strategies.

[0073] In the kth communication resource allocation case during the i-th period, terminal d n In the sudden business mThe boundary of the feasible region for communication resource allocation in the event of

[0074]

[0075] Where, For the kth communication resource allocation in the i-th time period, terminal d n In the sudden business m The boundary of the feasible region for communication resource allocation under the occurrence of the situation; For the i-th time period, under the k-th communication resource allocation condition, based on the terminal d n The boundary of the feasible domain of communication resource allocation for conventional business needs; For the i-th time period, under the k-th communication resource allocation condition, based on the terminal d n The sudden business c m The boundary of the feasible region for communication resource allocation changes according to the requirements.

[0076] At this time, the HPLC and wireless communication resource allocation strategy are expressed as

[0077]

[0078] Where, and Consider d for the i-th period respectively n Regular business and emergency business m Required HPLC and wireless communication resource allocation strategy; and They represent the number of packets allocated to terminal d when only regular services are considered in the i-th period. n HPLC resources and wireless resources; and The kth communication resource allocation in the i-th time period is based on d n The sudden business c m HPLC of demand and changes in wireless communication resource allocation strategies.

[0079] Step 3: Calculate the service resource redundancy interval. n In the sudden business m The business resource redundancy interval in the event of

[0080]

[0081] Where, β n,m (i) is terminal d n In the sudden business m Business resource redundancy interval in case of occurrence; B n (i) is terminal d nThe formula means that the business resource redundancy interval is expressed as the maximum distance between the actual resource allocation and the boundaries of each feasible domain of the business. When the allocation is not within the feasible domain, the redundancy interval is recorded as a negative sign.

[0082] Step 4: Calculate the service resource redundancy interval utility. Define the t-th time slot terminal d n The sudden business c m The utility of the business resource redundancy interval is U n,m (t), represents the terminal d n In the sudden business m In the event of a problem, the beneficial effect of redundant communication resources is expressed as

[0083]

[0084] Where V n,m (i) is terminal d n The sudden business c m Business value of sup (i) represents the upper bound of the redundant interval of all terminal service resources.

[0085] Define the i-th period, in the resource allocation scheme B n (i) Lower terminal d n The resource redundancy interval utility is Expressed as

[0086]

[0087] Where, For resource allocation plan B n (i) Lower terminal d n The resource redundancy interval utility of U n,m (t) is the terminal d of the tth time slot n The sudden business c m The utility of the business resource redundancy interval is U n,m (t); Indicates the sum of all time slots in a period

[0088] Step 5: Dual-mode communication resource allocation optimization. Taking the maximization of the utility of all terminal resource redundancy intervals as the optimization goal, dual-mode communication resource allocation optimization is performed. The optimization problem is expressed as

[0089]

[0090] Where B n (i) is terminal d n the allocation of resources; For resource allocation plan B n(i) Lower terminal d n The resource redundancy interval utility.

[0091] The optimization problem P1 is a convex optimization problem about the conditional extreme value of communication resource allocation, which can be solved according to the KKT condition.

[0092] (2) Small-scale adjustment method for HPLC dual-mode communication resource allocation based on resource redundancy interval and service resource redundancy value

[0093] Based on the dual-mode communication resource allocation optimization results in 2.2.1, further small-scale adjustments to the HPLC dual-mode communication resource allocation are performed based on the resource redundancy interval and the service resource redundancy value.

[0094] Step 1: Update the probability of burst traffic. Observe the service satisfaction of each terminal and update the terminal d in the next time slot. n The probability of a sudden business occurring P n,m (t+1).

[0095] Step 2: Calculate the terminal resource deviation. For terminals that cannot meet business requirements, calculate their resource deviation and define Δγ n (t) is the terminal d of the tth time slot n The resource deviation is expressed as

[0096]

[0097] Where, The terminal d of the tth time slot n The amount of resources required to meet business needs.

[0098] Step 3: Resource cutting. For terminals whose service performance is satisfied, resources are cut in proportion according to the resource redundancy interval and service resource redundancy value. Define the terminal d in the tth time slot n The resource redundancy is R n (t), expressed as

[0099]

[0100] Where B n (i) is terminal d n the allocation of resources; The terminal d of the tth time slot n The amount of resources required to meet business needs; R n (t) is the terminal d of the tth time slot n The resource redundancy is R n (t).

[0101] Then the terminal d of time slot t n The resource cutting amount is expressed as

[0102] S n (t) = α n (i)R n (t)

[0103]

[0104] Where S n (t) is the terminal d of the tth time slot n The amount of resource cutting; α n (i) is the resource cutting ratio determined according to the resource redundancy interval and the business resource redundancy value; σ(·) is the sigmoid activation function used to implement β n,m (i) Normalization; For terminal d n The business resource redundancy value represents the value brought by the terminal's own redundant resources; is the upper bound of the service resource redundancy value of all terminals. The formula means that the larger the terminal's resource redundancy interval, the smaller the service resource redundancy value, and the larger the amount of resources cut.

[0105] Step 4: Adjust terminal resources. Adjust the sum of all terminal cutting resources according to the terminal resource deviation and define G n (t+1) is the terminal d of the t+1th time slot n The amount of resources allocated after adjustment is expressed as

[0106]

[0107] Where G n (t+1) is the terminal d of the t+1th time slot n The amount of resources allocated after adjustment; Δγ n (t) is the terminal d of the tth time slot n Resource deviation; S n (t) is the terminal d of the tth time slot n The amount of resource cutting.

[0108] After adjustment, the final resource amount of the terminal that cannot meet the business demand is expressed as

[0109] B n (i) = B n (i)+G n (t+1) (15)

[0110] Where B n (i) is terminal d n Resource allocation of G n (t+1) is the terminal d of the t+1th time slot n The amount of resources allocated for supplementary adjustment.

[0111] The final resource amount of the terminal whose service performance is satisfied is expressed as

[0112] B n (i) = B n (i)-S n (t) (16)

[0113] Where B n (i) is terminal d n Resource allocation; S n (t) is the terminal d of the tth time slot n The amount of resource cutting.

[0114] Based on B n (i) Reallocate the HPLC and wireless communication resources of the terminals, observe the service satisfaction of each terminal, and feed the results back to step 1.
