Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource allocation method and apparatus, an electronic device, and a storage medium.

Background

In a 5G NR (5 th Generation Mobile Communication Technology New Radio, global 5G standard) system, a cell coverage is smaller than that of 4G, and more base stations are required to be built when an operator builds a network, which results in higher construction cost. Therefore, the problems of repeated construction, high cost, high energy consumption and the like of the base station can be solved by adopting a co-construction sharing mode, the use efficiency of resources is improved, the advanced network capability is quickly formed, the method is an important hand for implementing a new development concept and realizing a double-carbon target, and the high-quality, healthy and green development of the 5G industry is promoted.

The co-construction sharing reduces the network construction cost, but the air interface resources are limited, different operator users served by the cell can compete for the air interface resources with the cell bandwidth in the cell shared by the co-construction of the current base station, and a unified resource management method is not available.

In summary, the co-building sharing system of the 5G base station at the present stage has the following problems:

1. the air interface resources are limited and are not distributed uniformly. Although the network cost is reduced through co-construction sharing, the air interface resources are limited, so that the air interface resources are not reasonably divided, users among different operators compete for the air interface resources, conflicts among the co-construction shared operators are directly caused, and the network construction cost of the operators is reduced.

2. Operator user satisfaction decreases. The wireless base station network cannot be fully utilized, operators cannot schedule users in time, the service rate can be rapidly reduced and even dropped, the requirements of users of the operators cannot be effectively guaranteed, and the user experience can be reduced accordingly.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Referring to fig. 1, a flowchart illustrating steps of a resource allocation method provided in an embodiment of the present application is shown, where the resource allocation method may be applied to a base station, and as shown in fig. 1, the resource allocation method may include: step 101, step 102 and step 103.

Step 101: acquiring cell physical resources of a co-constructed shared cell and N operators corresponding to the co-constructed shared cell, wherein N is a positive integer greater than or equal to 2.

The embodiment of the application can be applied to the base station, namely, the execution subject is the base station. A base station refers to a radio transceiver station for information transfer with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. In this example, the base station may be a macro base station, a micro base station, a distributed base station, or the like, and specifically, the specific type of the base station may be determined according to actual situations, which is not limited in this embodiment.

In this embodiment of the present application, co-establishing a shared cell means that multiple operators co-establish a serving cell and share resources of the serving cell. The operator is a provider providing network services, and in this example, the operator may be an operator in china mobile, china unicom, china telecom, china radio and television, and the like.

The cell Physical Resource refers to a Physical Resource allocable by the co-established shared cell, that is, the number of Physical Resource Blocks (PRB) of the co-established shared cell. The PRB corresponds to 12 continuous subcarriers (15 kHz, 30kHz, etc. subcarriers) in the frequency domain, and is a time-series (half a subframe, 0.5 ms) resource in the time domain.

When resource allocation is performed on the co-established shared cell, the cell physical resources of the co-established shared cell and N operators corresponding to the co-established shared cell, that is, the N operators co-establish and share one serving cell, may be obtained. In this example, N is a positive integer greater than or equal to 2, that is, at least two operators share a serving cell.

After acquiring the cell physical resources of the co-established shared cell and the N operators corresponding to the co-established shared cell, step 102 is executed.

Step 102: and configuring the exclusive resource and the priority resource of each operator and the shared resources of N operators according to the physical resources of the cell.

In this example, dedicated resources refer to resources that can be occupied only by users to which the operator belongs.

The priority resource refers to a resource which is preferentially allocated to a user belonging to an operator and can be occupied by users of other operators.

The shared resource refers to a resource that can be occupied by all operators who establish a shared cell together.

After the cell physical resources of the co-established shared cell and the N operators corresponding to the co-established shared cell are obtained, the dedicated resources and the priority resources of each operator in the N operators and the shared resources of the N operators may be configured according to the cell physical resources of the co-established shared cell.

In the prior art, for a co-established shared cell, only the cell physical resources of the co-established shared cell are divided into priority resources and shared resources, as shown in fig. 7, (a) in fig. 7 is an existing resource configuration mode, and in this mode, there may be a higher priority of the user service of the next operator of the co-established shared cell, and more frequency domain resources are occupied, which may cause the user of another operator to fail to obtain a scheduling plan, and the service rate is reduced or even dropped, which affects the user experience. To solve this problem, the embodiment of the present application divides the cell physical resources into dedicated resources, priority resources and shared resources, as shown in fig. 7 (b). The exclusive resource allocated to each operator is only occupied by the user under the operator, so that the problems that the user of another operator cannot obtain a scheduling plan, the service rate is reduced, even the line is dropped and the user experience is influenced due to the fact that the user service priority is higher and the occupied frequency domain resource is more can be avoided.

In a general situation, dedicated resources and priority resources occupied by N operators co-building a shared cell are the same, and certainly may be different, at this time, the base station may configure allocation proportions of the dedicated resources, the priority resources, and the shared resources, and perform configuration of the dedicated resources, the priority resources, and the shared resources according to the allocation proportions. The resource configuration process may be described in detail below in conjunction with fig. 2.

Referring to fig. 2, a flowchart illustrating steps of a resource allocation method provided in an embodiment of the present application is shown, and as shown in fig. 2, the resource allocation method may include: step 201 and step 202.

Step 201: and acquiring a preset resource allocation proportion.

In this embodiment, the resource allocation ratio refers to a ratio of dedicated resources, priority resources, and shared resources that are preset for allocating the co-established shared cell. The specific value of the resource allocation ratio may be determined according to the service requirement, and this embodiment is not limited thereto.

After the cell physical resources of the co-established shared cell and the N operators corresponding to the co-established shared cell are obtained, the preset resource allocation proportion may be obtained.

After the preset resource allocation ratio is acquired, step 202 is performed.

Step 202: and configuring the exclusive resource and the priority resource of each operator and the shared resources of N operators according to the cell physical resource and the resource allocation proportion.

After the preset resource allocation proportion is obtained, the dedicated resource and the priority resource of each operator and the shared resources of the N operators can be configured according to the cell physical resource and the resource allocation proportion of the co-established shared cell. The specific allocation may be as follows:

1. when the amount of the dedicated resource and the amount of the priority resource of each operator are the same, the specific allocation method may include the following steps:

1. dividing physical resources of the cells according to the resource allocation proportion to obtain the total amount of exclusive resources, the total amount of priority resources and the total amount of shared resources;

2. and dividing N equal parts according to the total amount of the exclusive resources and the total amount of the priority resources to obtain the exclusive resources and the priority resources of each operator.

2. When the amount of the dedicated resource and the amount of the priority resource of each operator are different, the specific allocation method may include the following steps:

2. and dividing the total amount of the exclusive resources and the total amount of the priority resources according to the preset resource occupation proportion of each operator to obtain the exclusive resources and the priority resources of each operator.

In a specific implementation, the cell physical resources of the co-established shared cell may be divided into the operator resources of each operator according to the resource occupation proportion of each operator (which may be the same or different), and then the operator resources of each operator are divided according to the resource allocation proportion, so that the dedicated resources and the priority resources of each operator can be obtained, and meanwhile, the shared resources of N operators and the like can be obtained.

In practical applications, the resource allocation manner may be selected according to the service requirement, which is not limited in this embodiment.

Configuring exclusive resources, priority resources and shared resources of operators, and simultaneously configuring a maximum resource threshold of each operator, configuring exclusive, priority and maximum resource thresholds corresponding to each operator aiming at co-construction and sharing of N operators, and calculating and storing the exclusive, priority and maximum resources corresponding to each operator:

dedicated resource = DedicatedRatio cell physical resource.

Priority resource = (MinRatio-DedicatedRatio) × cell physical resource.

Maximum resource = MaxRatio cell physical resource.

The exclusive ratio (DedicatedRatio), the minimum ratio (MinRatio), and the maximum ratio (MaxRatio).

When resource allocation is performed, the resource allocated by each operator cannot exceed the maximum resource of the operator.

After configuring the dedicated resources and the priority resources of each operator and the shared resources of the N operators according to the cell physical resources and the resource allocation ratio, step 103 is executed.

Step 103: and performing resource allocation according to the exclusive resource, the priority resource and the shared resource.

After the dedicated resource and the priority resource of each operator and the shared resources of the N operators are configured according to the cell physical resource and the resource allocation proportion, resource allocation can be performed according to the dedicated resource, the priority resource and the shared resources. For example, 2 operators are allocated to a radio base station cell as an example, and the number of operators can be extended. The exclusive, preferential and shared resources of the operator 1 and the operator 2 are configured in the network management system, and the allocable resources of the users under each operator are controlled, so that when the number of users under the operator 1 and the operator 2 and the user service are greatly different, more cell shared resources can be allocated to the users under the operator 1, the purpose of fully utilizing the cell air interface resources is achieved, the exclusive resources are reserved for the operator 2, and the service and the user experience of the exclusive users under the operator 2 are guaranteed. When the number of users under the operator 2 increases, the priority resource can be preferentially used when the exclusive resource is insufficient, then the shared resource can be used together with the users of the operator 1, and the services of the users under the two operators are simultaneously guaranteed through algorithm control.

It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation to the embodiments.

The embodiment of the application can meet the service requirements of users under different operators by pre-configuring the exclusive resources of each operator, and improves the user experience. Meanwhile, resource allocation is carried out according to the exclusive resource and the priority resource of each operator and the shared resource of the co-established shared cell, so that the resource utilization rate can be improved, the air interface resource of the base station can be fully utilized under the condition that the hardware cost is not increased, and the network construction cost of the operators is reduced.

The resource allocation method can be described in detail in conjunction with fig. 3 as follows.

Referring to fig. 3, a flowchart illustrating steps of another resource allocation method provided in an embodiment of the present application is shown, and as shown in fig. 3, the resource allocation method may include: step 301, step 302, step 303 and step 304.

Step 301: initializing the N operators.

In this embodiment, when configuring dedicated resources, priority resources, and shared resources of N operators and allocating resources in a co-established shared cell, the N operators may be initialized.

In a specific implementation, in a cell operator algorithm configuration parameter table, a co-establishment sharing related parameter may be added, where the co-establishment sharing related parameter includes a "co-establishment sharing policy switch," an ID of each operator, and a parameter resource configuration ratio such as a dedicated (DedicatedRatio), a minimum (MinRatio), a maximum (MaxRatio) resource configuration ratio, and after receiving configuration, a base station associates the operator with a configured dedicated, minimum, and maximum resource ratio threshold, and adds a check to an operator sharing policy parameter, specifically:

1. when only one operator is configured, a local 'co-establishment sharing policy switch' is set to be closed, that is, the sharing policy parameters of the operator are not validated, and the user of the operator can use all bandwidth resources in the cell.

2. When the 'co-construction sharing policy switch' is turned on, N operator groups are locally maintained according to operators, and the affiliated operator IDs and the operator sharing policy parameters are stored.

3. And turning on a 'co-construction sharing strategy switch', refreshing the parameters of the operator without the sharing strategy parameters, and if the operator does not configure the sharing strategy parameters of the operator, clearing the exclusive and priority resource numbers of the operator.

4. The 'co-construction sharing strategy switch' is closed, and the configured co-construction sharing strategy parameters are not used.

After initializing the N operators, step 302 is performed.

Step 302: and acquiring the user equipment under the co-established shared cell.

After initializing the N operators, the ue in the co-established shared cell, that is, the device accessing the co-established shared cell, may be obtained.

After the user equipment in the co-established shared cell is acquired, step 303 is executed.

Step 303: and acquiring a target operator in the N operators to which the user equipment belongs according to the operator identification corresponding to the user equipment.

The operator identity (i.e. OperatorId) may be used to indicate the identity of the operator to which the user equipment belongs.

The operator identifier may be configured by the base station, and when the user equipment accesses the base station and provides a network service for the user equipment through a co-established shared cell, the base station may configure a corresponding operator identifier for the user equipment to indicate an operator to which the user equipment belongs. In a specific implementation, when the parameter is not configured after the user equipment accesses, initializing the OperatorId to be equal to an invalid value. After the parameters are configured, if the 'co-construction sharing strategy switch' is turned on, the interface parameter Opera Id is valid (0-N), and the operator sharing strategy parameters are configured, associating the user with the corresponding operator, and allocating cell empty resource for the user according to the sharing strategy parameters configured by the operator.

The target operator refers to an operator to which the user equipment belongs in the N operators.

After the user equipment in the co-established shared cell is obtained, the operator identifier corresponding to the user equipment can be obtained, and a target operator in the N operators to which the user equipment belongs is obtained according to the operator identifier.

After acquiring a target operator of the N operators to which the user equipment belongs according to the operator identifier corresponding to the user equipment, step 304 is executed.

Step 304: and distributing the resources of the target operator according to the resource allowance of the target operator and the service resource occupation amount of the user equipment.

The resource balance refers to the remaining amount of resources of the target operator, and in this example, the resource balance of each operator may include: an exclusive resource margin and a priority resource margin.

The service resource occupation amount refers to the resource occupation amount of the service of the network service required by the access of the user equipment to the base station.

After a target operator in the N operators to which the user equipment belongs is obtained according to the operator identifier corresponding to the user equipment, the resource allowance of the target operator and the service resource occupation amount of the user equipment can be obtained.

After the resource surplus of the target operator and the occupied amount of the service resources of the user equipment are obtained, the resources of the target operator can be distributed according to the resource surplus of the target operator and the occupied amount of the service resources of the user equipment. In a specific implementation, if the dedicated resource of the resource pool of the operator is not full, other user equipment of the operator may use the part of the resource. If the priority resource of the resource pool of the operator is not full, other user equipment including the user equipment of the operator and other operators can use the part of resource, and the user equipment of the shared resource operator and other operators can use the part of resource. The implementation can be described in detail as follows in conjunction with fig. 4.

Referring to fig. 4, a flowchart illustrating steps of another resource allocation method provided in an embodiment of the present application is shown, and as shown in fig. 4, the resource allocation method may include: step 401, step 402, step 403 and step 404.

Step 401: and determining the exclusive resource surplus and the priority resource surplus of the target operator according to the resource surplus.

In this embodiment, the dedicated resource remaining amount and the priority resource remaining amount of the target operator may be determined according to the resource remaining amount of the target operator. The dedicated resource remaining amount refers to a remaining amount of a dedicated resource of a target operator. The remaining amount of priority resources refers to the remaining amount of priority resources of the target operator.

After the exclusive resource remaining amount and the priority resource remaining amount of the target operator are determined according to the resource remaining amount, step 402 is executed.

Step 402: and under the condition that the exclusive resource residual amount is greater than or equal to the service resource occupation amount, allocating the exclusive resource of the target operator to the user equipment.

After the exclusive resource surplus and the priority resource surplus of the target operator are determined according to the resource surplus, the size relation between the exclusive resource surplus and the service resource occupation amount of the target operator can be compared.

And under the condition that the exclusive resource residual amount of the target operator is greater than or equal to the service resource occupation amount, allocating the exclusive resource of the target operator to the user equipment.

Step 403: and comparing the size relation between the occupation amount of the service resources and the residual amount of the priority resources under the condition that the exclusive resource residual amount is smaller than the occupation amount of the service resources.

And under the condition that the exclusive resource residual quantity of the target operator is smaller than the occupied quantity of the service resource, comparing the size relation between the occupied quantity of the service resource and the priority resource residual quantity of the target operator.

Step 404: and distributing the priority resources of the target operator to the user equipment under the condition that the remaining amount of the priority resources is greater than or equal to the occupied amount of the service resources.

And distributing the priority resources of the target operator to the user equipment under the condition that the residual quantity of the priority resources of the target operator is greater than or equal to the occupied quantity of the service resources.

In the process of downlink resource allocation, downlink scheduling queuing can be performed according to the user service priority, and one user equipment in each row can be determined according to an operator to which the user equipment belongs as follows:

1. if the number of queued users of the operator to which the user belongs is greater than N (the maximum number of users scheduled per TTI), no queuing is performed;

2. the number of queued users of the operator to which the user belongs is increased by 1.

After downlink scheduling queuing, the base station calculates and updates the number of PRBs (resource blocks) related to allocation according to the shared strategy parameters of each operator configured by the cell, and the specific flow is as follows:

1) Updating the available maximum resource Nprbmax of the current time slot = cell physical resource;

2) For all operators Pi (0 < = Pi < P) of a cell, calculating the exclusive priority reservation quantity, the exclusive reservation quantity, the priority and the maximum resource PRB number of the operators, wherein the operators without queuing users only reserve 'exclusive resources' and do not reserve 'priority resources';

3. slot sharable resource = number of currently available PRBs-sum (operator Pi proprietary-preferred reservation), where sum (operator Pi) is summed for all operators configured for the cell.

When downlink resource allocation is performed, the number of the users allocated with the operator resource to which the user belongs is increased by 1 every time one user is allocated.

And updating the resource occupation condition of the operator if the index of the operator to which the SUMIMO user belongs is effective when the 'co-construction sharing strategy switch' is turned on after the SUMIMO user is allocated.

Meanwhile, the number of resources of the operator needs to be counted in real time: the number of occupied resources of an operator = the number of PRBs allocated to the user;

if the "number of operator resource allocation users" is equal to the "number of operator queuing users" (operator that has been scheduled), the operator specific priority reservation = Max (0, operator specific priority reservation-operator priority resource-the number of PRBs allocated by the user);

operator specific reservation = Max (0, operator specific reservation-number of PRBs allocated by this user);

otherwise, operator specific priority reservation = Max (0, operator specific priority reservation-number of PRBs allocated by the user);

operator specific reservation = Max (0, operator specific reservation-number of PRBs allocated by this user).

For allocating the first time PRB resources, if the operator index to which the user belongs is valid, the "number of currently available PRBs" needs to be considered to deduct the dedicated priority resources of the operator, and the corresponding algorithm parameters are as follows:

operator Pi specific priority remaining resource = number of currently available PRBs-sum (operator j specific priority reservation), where sum (operator j) is the sum of all operators configured for the cell;

operator Pi-specific remaining resources = number of currently available PRBs-sum (operator j-specific reserved amount), where j is as above;

operator Pi remaining resources = current available PRB number;

when MUMIMO resources are allocated, when a pairable set is put in for the first time, the information of an operator to which the set belongs needs to be recorded, and only users to which the same operator belongs can be paired in subsequent pairing.

When user resources are allocated under an operator Pi, the current available PRB number is calculated according to the following process:

1) If operator-specific priority remaining resources > =0 within the cell, the number of available PRBs is max (0,min ((operator Pi-specific + priority + specific priority remaining resources), max resources of operator Pi) -operator Pi occupied resources).

2) Otherwise, if the intra-cell operator Pi dedicated remaining resource > =0.

The number of available PRBs is max (0,min (min (operator Pi dedicated + preferred, operator Pi dedicated + dedicated remaining resources), operator Pi max resources) -operator Pi occupied resources).

3) Otherwise, the number of available PRBs is max (0,min (operator Pi is dedicated, operator Pi has resources left) -operator Pi has occupied resources).

And according to the user traffic, allocating resources to the user within the range of the number of the available PRBs, and ending the user resource allocation process.

According to the method and the device, when the exclusive resource surplus of the target operator meets the user service requirement, the exclusive resource of the target operator is distributed to the user equipment, when the exclusive resource does not meet the user service requirement, and the priority resource surplus of the target operator meets the user service requirement, the priority resource of the target operator is distributed to the user equipment, so that the service requirements of different operators can be met to the greatest extent.

In this embodiment, when the remaining amount of the priority resources of the target operator is less than the occupied amount of the service resources of the user equipment, the remaining amount of the priority resources of other operators of the co-established shared cell may be obtained, and if the remaining amount of the priority resources of other operators meets the user requirement, the priority resources of other operators are allocated to the user equipment. This implementation can be described in detail below in conjunction with fig. 5.
