Description

Resource allocation method, device and readable storage medium

Technical Field

Embodiments of the present application relate to the field of communications technologies, and in particular, to a resource allocation method and apparatus, and a readable storage medium.

Background

The fifth generation (5G) communication system introduces a slice function, and the 5G communication system may divide one or more slices into one slice group, and implement management of radio resources based on the slice group, so that the radio resources are isolated and shared between the slices. However, when a service exists in multiple scenes (e.g., multiple local area network scenes or public network scenes) and radio resource management needs to be performed on the service, a slice id needs to be configured for each scene, and then all slice ids need to be configured in a slice group. And the terminal can not process the services corresponding to a plurality of different slice identifiers at the same time, so the flexibility of managing the wireless resources is poor only based on the slice group.

In order to improve the flexibility of managing the wireless resources, each service flow may be configured with a 5G quality of service identifier (5 QI), and the wireless resources may be managed according to the 5QI of each service, and the terminal may simultaneously process a plurality of services corresponding to different 5QI, thereby improving the flexibility of managing the wireless resources. However, when one traffic flow is configured with a slice id and a 5QI, the base station performs radio resource management based on both the slice id and the 5QI, which may cause confusion in radio resource management.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in other sequences than those illustrated or described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the embodiments of the application, as detailed in the appended claims.

It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and/or components.

Before the embodiments of the present application are described, terms related to the embodiments of the present application will be explained.

1. Slicing: refers to a logically isolated network for supporting specific network capabilities and network characteristics, for example, part of the network functions may be shared in multiple slices to meet the differentiated demands of different 5G services for the network. Generally, the network characteristics of slices of different scenes are different, and the slices are required to be isolated from each other and not to influence each other.

For example, enhanced mobile broadband (eMBB) scenes require large bandwidth and low latency for slicing. Slices of an internet of things (MIOT) scene require to support mass terminal access, but have small bandwidth and no requirement on time delay. Ultra-high reliable and ultra-low latency communication (URLLC) scenarios require large bandwidth and ultra-low latency. Slices may also be applied to other different scenes, without limitation.

Wherein each slice may have a slice identification. For example, the slice identifier may include a Public Land Mobile Network (PLMN), a service type (SST), and a Slice Differentiator (SD).

2. PLMN: refers to a network established and operated for the purpose of providing land mobile communication services. Different PLMN values may correspond to different networks.

For example, as shown in table 1, when the PLMN takes the value of 46000, the network providing the land mobile service may be a network provided by the first operator. When the PLMN value is 46001, the network providing the land mobile service may be a network provided by the second operator. When the PLMN takes the value of 46011, the network providing the land mobile service may be a network provided by a third operator.

TABLE 1 PLMN and network type correspondence table

It should be noted that the data in table 1 are merely exemplary. In the embodiment of the present application, other network types and other PLMN values may also be included, without limitation.

3. SST: refers to the behavior of the intended network slice to characterize aspects of features and traffic. Different SST values may correspond to different slice scenes.

For example, as shown in table 2, when SST is 0, the slice scene may be an eMBB scene. When the SST value is 1, the slice scene may be a URLLC scene. When the SST value is 2, the slice scene may be a MIoT scene. When the SST value is 4, the slice scene may be a vehicle to electronics (V2X) scene.

Table 2 correspondence table between SST and slice scene

Slicing scene	SST
		eMBB	0
URLLC	1
		MIoT	2
V2X	3

It should be noted that the data in table 2 are merely exemplary. In the embodiment of the present application, other slice scenes and SSTs may also be included, without limitation.

4. SD: refers to the addition of a network slice type that may be used to further distinguish between multiple network slices of the same SST. The value of the SD is defined by an operator, and the operator can make the SD value according to the specific requirements of the actual situation on slicing/service. For example, when the value of SD is 0, the network slice type is type 1. When the SD value is 1, the network slice type is type 2. When the value of SD is 2, the network slice type is type 3.

5. Slice identification group: refers to a combination comprising one network slice or a plurality of network slices. The 5G network can realize the management of the wireless resources based on the slice group, so that the wireless resources can be flexibly isolated and shared among the slices.

In one example, the slice identification group may include a first slice identification group (slice _ group1), and as shown in table 3 below, the slice _ group1 may include 2 slice identifications, and the 2 slice identifications may respectively include a first slice identification (PLMN 46001, SST 0, SD 1), and a second slice identification (PLMN 46001, SST 0, SD 2).

TABLE 3 first slice identification group

It should be noted that the data in table 3 are merely exemplary. In this embodiment of the application, the first slice identifier group may further include other slice identifiers, which is not limited.

The radio resource may include a Radio Resource Control (RRC) user number, a Data Radio Bearer (DRB), a Physical Resource Block (PRB), and the like.

In order to ensure transmission of the service flow corresponding to the slice identifier, a wireless resource may be reserved for the service flow corresponding to the slice identifier, and the reservation mode of the wireless resource may include the following two modes:

the first method is admission control.

The admission control refers to admission control based on the number of users, admission control based on the number of DRBs, or admission control based on PRBs. The following describes the 3 admission control modes:

(1) and admission control based on the number of users.

When a user establishes a slice service, if the number of users of a slice group in which the current slice is located does not reach the user number resource threshold of the slice group, the user can establish the slice service. Otherwise, the user cannot establish the slicing service.

(2) DRB-based admission control.

When a user establishes a slice service, if the DRB number of the slice group in which the current slice is positioned does not reach the DRB number resource threshold of the slice group, the user can establish the slice service. Otherwise, the user cannot establish the slicing service.

(3) PRB-based admission control.

When a user establishes a slice service, if the wireless resource required by the PRB admission of the slice group in which the current service is positioned does not reach the PRB resource threshold of the slice group, the user can establish the slice service. Otherwise, the user cannot establish the slicing service.

And a second mode is PRB reservation.

The network device may allocate different PRB radio resources for different slice groups and allocate the PRB radio resources to different slice groups with a scheduler. Therefore, when the wireless resource of one slice group is in short supply, the service quality of the other slice group is not influenced, and a certain resource isolation degree is achieved.

6. 5G quality of service identifier (5G quality of service identifier, 5 QI): refers to a scalar which can be used to index the quality of service (QoS) characteristics of the 5G corresponding to the service.

In one example, one or more 5 QIs may constitute one 5QI group, e.g., as shown in table 4, the 5QI group may include a first 5QI group (5QI _ group1), the 5QI _ group1 may include 2 5 QIs, and the 2 5 QIs may be 80, 82.

TABLE 4 first 5QI group

5QI group	5QI
		5QI_group1	80，82

It should be noted that the data in table 4 are merely exemplary. In the embodiment of the present application, the first 5QI group may further include other 5QI groups, which is not limited.

The 5G communication system introduces a slicing function. The 5G communication system may divide one or more slices into one slice group and implement management of radio resources based on the slice group such that the radio resources are isolated and shared between the slices. However, when one service exists in multiple scenarios (for example, multiple local area network scenarios or public network scenarios) at the same time and radio resource management needs to be performed on the service, slice identifiers and 5QI of different scenarios need to be configured in the base station, and then slice groups need to be configured, and these slice identifiers are all added into the slice groups, which makes the overall operation complicated. If the resource management is performed on the 5QI, only the corresponding 5QI and different slice identifiers need to be configured at the base station, and the task of configuring the slice group does not need to be performed. In addition, when the number of slice identifiers is large, the process of configuring the slice identifiers by the slice group is likely to cause mismatching, which is not as convenient as 5QI management.

In addition, the current terminal slicing concurrency technology is low in maturity. For example, when a terminal performs one slicing service, there is no way to perform another slicing service at the same time. But the terminal may use the general service of the large network slice (for example, the general service may be WeChat service) and also use the special service of the specific slice. Since it is impossible to request a terminal to perform a large network service when using a specific slice service, it is not feasible to perform radio resource management using a slice group. But resource management based on 5QI does not have this problem.

In order to improve the flexibility of managing the radio resources, each service flow can be configured with one 5QI, and the radio resources can be managed according to the 5QI of each service, so that the flexibility of managing the radio resources is improved. However, when one traffic flow is configured with both the slice id and the 5QI, the network device performs radio resource management based on both the slice id and the 5QI, which may cause confusion in radio resource management.

In view of this, an embodiment of the present application provides a resource allocation method, including: when the network device receives a request message sent by the terminal device for requesting allocation of radio resources for the first service flow, the network device may match the slice identifier group configured by the network device according to the first slice identifier of the first service flow and the first 5QI of the first service flow in the request message. When the first slice identifier is an identifier in the slice identifier group, the network device may allocate a radio resource to the first service flow by using a preset radio resource corresponding to the slice identifier group.

It should be noted that the service flow in the embodiment of the present application may be a long-term evolution voice over-term evolution (voice) service, a game service, an audio service, a video service, and the like.

The method provided by the embodiment of the application is described in detail below with reference to the attached drawings.

Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

It is noted that, in the present application, words such as "exemplary" or "for example" are used to mean exemplary, illustrative, or descriptive. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

The resource allocation method provided in the embodiment of the present application is described below with reference to the network architecture shown in fig. 1.

Fig. 3 provides a resource allocation method for a network device, where the resource allocation method is applied to the network device, and the network device may be the network device 12 in fig. 1, and may also be a device, such as a chip, in the network device 12. As shown in fig. 3, the method includes the following S301-S303:

s301, the network device receives a first request message sent by the terminal device.

The terminal device may be the terminal device 11 in fig. 1, and may also be a device, such as a chip, in the terminal device 11.

The first request message is used for requesting to allocate radio resources for the first service flow. The first request message includes a first slice identifier of the first traffic flow and a first 5QI of the first traffic flow, and the PLMN identified by the first slice is the first PLMN. The slice identifier and 5QI may refer to the explanations in the noun explanations above.

In one example, the terminal device may send a first request message to the network device in response to the first operation. Correspondingly, the network device receives the first request message sent by the terminal device. For example, when the first service flow is a volume service, the first operation may refer to an operation in which the user calls another user using the terminal device. For another example, when the first service flow is an audio service or a video service, the first operation may be an operation of a user using a terminal device to obtain an audio/video radio resource request, or the like.

And S302, when the network device is configured with a slice identifier group and a 5QI group and the first slice identifier is an identifier in the slice identifier group, the network device allocates a radio resource to the first service flow by using a preset radio resource corresponding to the slice identifier group.

The description of the slice identifier group may refer to the description in the above noun explanation, and is not repeated. For example, the slice identification group may be slice _ group1 in table 3 above.

In an example, as shown in fig. 4, a schematic diagram of preset radio resources corresponding to a slice identifier group according to an embodiment of the present application is shown. The slice identification group includes an identification of slice 1 and an identification of slice 2. The preset radio resources corresponding to the slice identifier group are a first radio resource of a first preset number, a second radio resource of a second preset number, and a third radio resource of a third preset number. For example, the first preset number may be 1% of the total number of radio resources, or may be 0%. The second predetermined number may be 10% of the total number of radio resources, and the third predetermined number may be 20% of the total number of radio resources.

The diagram also includes non-slice group radio resources that are not available to the slice group.

Wherein, the first radio resource is a dedicated radio resource of the first service flow.

The second radio resource is a radio resource of the first traffic flow with priority usage right. For example, in a case that a first slice identifier of a first traffic flow is an identifier in a slice identifier group, and a second slice identifier of a second traffic flow is not an identifier in the slice identifier group, if both the first traffic flow and the second traffic flow require a second radio resource, the network device may allocate the second radio resource to the second traffic flow after allocating the second radio resource to the first traffic flow.

For another example, if the first slice identifier of the first service flow is an identifier in the slice identifier group and the second slice identifier of the second service flow is also an identifier in the slice identifier group, if both the first service flow and the second service flow require the second wireless resource, the network device may allocate the second wireless resource to the first service flow and the second service flow according to the sequence of the received request messages of the first service flow and the second service flow.

The third radio resource is a shared resource. I.e. traffic flows that can be used by the first traffic flow but do not have preferential usage rights. For example, if the first service flow and the second service flow both require the third wireless resource, the network device may allocate the third wireless resource to the first service flow and the second service flow according to the sequence of the received request messages of the first service flow and the second service flow.

In one example, when the slice identification group is slice _ group1 in table 3, if the first slice identification of the first traffic flow is PLMN 46001, SST ═ 0, and SD ═ 1, the first slice identification is identified as the identification in the slice identification group.

In yet another example, the network device may allocate a third radio resource for the first traffic flow in the event that the network device determines that the first slice identity is not an identity in the set of slice identities. For example, in a case that the slice identification group is slice _ group1, the first slice identification is PLMN 46001, SST 0, and SD 0, the network device may determine that the first slice identification is not an identification in the slice identification group.

In a possible implementation manner, when it is determined that a first slice identifier of a first service flow is an identifier in a slice identifier group, a network device allocates a radio resource to the first service flow by using a preset radio resource corresponding to the slice identifier group.

In one example, in a case that the preset wireless resource is a resource block, the network device may determine, according to a size of the first traffic flow and a data amount that each resource block may carry, an amount of the preset wireless resource for carrying the first traffic flow. After determining the number of the preset wireless resources, the network device may allocate the wireless resources to the first traffic flow according to the number of the preset wireless resources.

Specifically, the network device may allocate the radio resource to the first service flow according to the number of the preset radio resource, where the allocating may include the following 3 cases:

in case 1, when the number of the radio resources carrying the first service flow is less than or equal to a first preset number, the radio resources allocated by the network device for the first service flow are the first radio resources.

For example, when the first preset number is 2% of the total number of radio resources and the number of radio resources carrying the first traffic flow is 1% of the total number of radio resources, the first radio resources meet the requirement of carrying the first traffic flow. In this case, the radio resource allocated by the network device for the first traffic flow is the first radio resource.

And 2, when the number of the wireless resources bearing the first service flow is greater than a first preset number and the first difference is less than or equal to a second preset number, the wireless resources allocated to the first service flow by the network device include wireless resources in the first wireless resources and the second wireless resources.

The first difference is a difference between the number of the wireless resources bearing the first service flow and a first preset number.

For example, when the first preset number is 2% of the total number of radio resources, the second preset number is carried by 10% of the total number of radio resources, and the number of radio resources carrying the first service flow is 3% of the total number of radio resources, the first radio resources cannot meet the requirement of carrying the first service flow. In this case, the radio resources allocated by the network device for the first traffic flow include radio resources of the first radio resource and the second radio resource.

And 3, when the first difference is greater than the second preset number, the radio resources allocated to the first service flow include radio resources in the first radio resource, the second radio resource and the third radio resource.

For example, when the first preset number is 2% of the total number of radio resources, the second preset number is 10% of the total number of radio resources, and the number of radio resources carrying the first service flow is 15% of the total number of radio resources, the sum of the first radio resources and the second radio resources cannot meet the requirement of carrying the first service flow. In this case, the radio resources allocated by the network device for the first traffic flow include radio resources of the first radio resource, the second radio resource, and the third radio resource.

Further, when the network device allocates the radio resource for the first service flow, if there is a second service flow corresponding to the slice identifier group, the manner of allocating the radio resource for the second service flow is the same as that of allocating the radio resource for the first service flow.

S303, when the network device is not configured with the slice identifier group and is configured with a 5QI group, and the first 5QI is the identifier of the 5QI group, and the first PLMN is the same as the PLMN configured by the network device, the network device uses the preset radio resource corresponding to the 5QI group to allocate radio resource to the first service flow.

In one example, in the case that the slice identification group is slice _ group1 in table 3, the first slice identification is PLMN 46001, SST 0, SD 0, or the first slice identification is PLMN 46001, SST 1, SD 0, and the 5QI group is 5QI _ group1, first 5QI 80, or first 5QI 46082, and the network device is configured PLMN 46001, the network device may determine that the first slice identification is not an identification in the slice identification group, the first 5QI is an identification of the 5QI group, and the first PLMN is the first PLMN.

Based on the above S301 to S303, the network device receives a first request message, where the first request message is used to request allocation of radio resources for the first service flow, and the first request message includes a first slice identifier of the first service flow and a first 5QI of the first service flow. And when the network equipment is configured with the slice identifier group and the first slice identifier is the identifier in the slice identifier group, allocating the radio resource for the first service flow by using the preset radio resource corresponding to the slice identifier group. Therefore, the slice identifier group configured with the network device can be matched through the first slice identifier and the first 5QI of the first service flow, and the preset wireless resources corresponding to the slice identifier group are allocated for the first service flow under the condition that the first slice identifier is successfully matched with the identifiers in the slice identifier group, but the corresponding preset wireless resources are not allocated for the first service flow according to the 5QI, so that the problem that when one service flow is simultaneously configured with the slice identifier and the 5QI, the network device performs wireless resource management based on the slice identifier and the 5QI, and the wireless resource management of the network device is disordered can be avoided.

One possible embodiment, as shown in fig. 5, when the network device is configured with a slice identification group and a 5QI group, the method may further include S501-S502:

s501, when the first slice identifier is a slice identifier in the slice identifier group and the first 5QI is an identifier of the 5QI group, the network device allocates a radio resource to the first service flow by using a preset radio resource corresponding to the slice identifier group.

In one example, in the case that the slice identification group is slice _ group1 in table 3, the first slice identification is PLMN 46001, SST 0, SD 1, and the 5QI group is identification 5QI _ group1 in table 4, and the first 5QI is 80, the network device may determine that the first slice identification is an identification in the slice identification group, and the first 5QI is an identification of the 5QI group.

And S502, when the first slice identifier is not the slice identifier in the slice identifier group, the first 5QI is the identifier of the 5QI group, and the first PLMN is the same as the PLMN configured by the network device, the network device allocates the radio resource to the first service flow by using the preset radio resource corresponding to the 5QI group.

The number of the preset wireless resources corresponding to the 5QI group is different from the number of the preset wireless resources corresponding to the slice identifier group. For example, the preset radio resources corresponding to the 5QI group may include: a fourth preset number of first radio resources, a fifth preset number of second radio resources, and a sixth preset number of third radio resources. The fourth preset number may be 10% of the total number of radio resources, the fifth preset number may be 30% of the total number of radio resources, and the sixth preset number may be 60% of the total number of radio resources.

Further, when the network device allocates the radio resource for the first traffic flow, if there is a second traffic flow corresponding to the 5QI group, the manner of allocating the radio resource for the second traffic flow is the same as that of allocating the radio resource for the first traffic flow.

Specifically, the network device may allocate the radio resource to the first service flow according to the preset radio resource corresponding to the 5QI group, where the allocating may include the following 3 cases:

in case a, when the number of the radio resources carrying the first service flow is less than or equal to the fourth preset number, the radio resources allocated to the first service flow are the first radio resources.

For example, when the fourth preset number is 10% of the total number of radio resources, and the number of radio resources carrying the first traffic flow is 2% of the total number of radio resources, the first radio resource satisfies the requirement of carrying the first traffic flow. In this case, the radio resource allocated by the network device for the first traffic flow is the first radio resource.

And b, when the number of the wireless resources bearing the first service flow is greater than the fourth preset number and the second difference is less than or equal to the fifth preset number, the wireless resources allocated to the first service flow comprise wireless resources in the first wireless resources and the second wireless resources.

And the second difference is the difference between the number of the wireless resources bearing the first service flow and a fourth preset number.

For example, when the fourth predetermined number is 10% of the total number of radio resources, the fifth predetermined number is carried by 30% of the total number of radio resources, and the number of radio resources carrying the first traffic flow is 20% of the total number of radio resources, the first radio resource cannot meet the requirement of carrying the first traffic flow. In this case, the radio resources allocated by the network device for the first traffic flow include radio resources of the first radio resource and the second radio resource.

And c, when the second difference is greater than the fifth preset number, the radio resources allocated to the first service flow comprise radio resources in the first radio resources, the second radio resources and the third radio resources.

For example, when the first preset number is 10% of the total number of radio resources, the second preset number is 30% of the total number of radio resources, and the number of radio resources carrying the first traffic flow is 50% of the total number of radio resources, the sum of the first radio resources and the second radio resources cannot meet the requirement of carrying the first traffic flow. In this case, the radio resources allocated by the network device for the first traffic flow include radio resources of the first radio resource, the second radio resource, and the third radio resource.

Based on the above S501 to S502, when the network device is further configured with a 5QI group, the network device may match the first slice identifier with the slice identifier group configured by itself, and match the first 5QI with the 5QI group configured by itself. And allocating the preset wireless resource corresponding to the slice identifier group for the first service flow under the condition that the first slice identifier is successfully matched with the identifier in the slice identifier group. And under the conditions that the matching of the first slice identifier and the identifier in the slice identifier group fails, the matching of the first 5QI and the identifier of the self-configured 5QI group succeeds, and the first PLMN is the same as the PLMN configured by the network equipment, allocating preset wireless resources corresponding to the 5QI group to the first service flow. The problem that when one service flow is configured with the slice identifier and the 5QI at the same time, the wireless resource management of the network equipment is disordered is solved.

One possible embodiment, as shown in fig. 6, when the network device is not configured with the slice identifier group but is configured with the 5QI group, the embodiment of the present application may further include the following S601:

s601, when the first 5QI is not the identifier of the 5QI group, the radio resource allocated to the first traffic flow is the third radio resource.

In one example, where the 5QI group is the identifier 5QI _ group1 of table 4 above, and the first 5QI is 9, the network device may determine that the first 5QI is not the identifier of the 5QI group.

In yet another example, the network device may also be configured with a PLMN. For example, the PLMN configured by the network device may be 46001.

For example, when the PLMN configured by the network device is 46001, the slice identifier PLMN corresponding to the traffic flow is 46011, SST is 0, SD is 0, and 5QI is 80, that is, the PLMN configured by the network device is different from the PLMN of the traffic flow, the network device may determine that the radio resource allocated for the first traffic flow is the third radio resource.

In one possible embodiment, when the network device is not configured with the slice id group and is not configured with the 5QI group, the radio resource allocated by the network device for the first traffic flow is the third radio resource.

Based on the above S601, when the network device is not configured with the slice identifier group but configured with the 5QI group, the network device may directly match the first 5QI with the 5QI group configured by the network device, and when the identifier of the 5QI group, which is the first 5QI, and the first PLMN are the same as the PLMN configured by the network device, allocate radio resources for the first service flow according to preset radio resources corresponding to the 5QI group. When the first 5QI is not the identity of the 5QI group, the radio resource allocated for the first traffic flow is a third radio resource. In this way, a specific radio resource allocation manner can be determined when the network device is not configured with the slice id group but configured with the 5QI group.

All the schemes in the above embodiments of the present application can be combined without contradiction.
