Description

Secondary cell activation method and device
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a method and a device for activating a secondary cell.
Background
A fifth generation mobile communication technology (5G) system inherits an aggregated carrier technology of a long term evolution-advanced (LTE-a) system and introduces a network slicing technology. Both the carrier aggregation technology and the network slicing technology can be used for allocating resources for the terminal device, but when the two technologies are used for resource allocation, the resource allocation between the two technologies generates mutual interference, so that the effect of resource allocation is influenced, and the network performance is reduced.
Disclosure of Invention
The application provides an auxiliary cell activation method and device, which can determine and activate a target auxiliary cell based on the number of first target network slices determined by the available load of network slices used by terminal equipment (UE), thereby realizing the effect of activating the auxiliary cell based on the network slices, reducing the mutual interference of a network slice technology and a carrier aggregation technology in the resource allocation process, ensuring the effect of resource allocation and improving the network performance.
In order to achieve the purpose, the following technical scheme is adopted in the application:
in a first aspect, the present application provides a method for activating a secondary cell, including: first, a network slice with an available load used by the terminal device UE smaller than a first available load threshold is determined as a first target network slice. And then, if the ratio of the number of the first target network slices to the total number of the network slices used by the UE is greater than a preset ratio, activating a target secondary cell, wherein the target secondary cell is one or more of secondary cells configured for the UE but not activated.
In the process, whether the target auxiliary cell is activated or not is determined based on the available load of the network slice, so that the effect of activating the auxiliary cell based on the network slice is realized, the mutual interference of a network slice technology and a carrier aggregation technology during resource allocation is reduced, and the effect of resource allocation is ensured. The larger the available load of the network slice is, the better the performance of the network slice is, and the network performance can be better ensured. Therefore, by using the ratio of the number of network slices with the available load larger than the first available load threshold to the total number of network slices used by the UE, the current network performance can be well determined, and the target secondary cell is activated to improve the network performance under the condition that the network performance is poor, that is, the ratio is larger than the preset ratio.
In one possible implementation, determining that the network slice to which the available load adapted by the UE is smaller than the first available load threshold is the first network slice includes: the maximum data transmission quantity of the network slice used by the UE, the actual data transmission quantity of the network slice used by the UE and the data quantity to be transmitted of the network slice used by the UE are obtained. And then, determining the maximum data transmission quantity of the network slice as the difference value between the actual data transmission quantity and the data quantity to be transmitted as the available load of the network slice used by the UE. Finally, if the available load of the network slice used by the UE is smaller than the first available load threshold, the network slice is determined to be the first target network slice.
The larger the available load of the network slice is, the better the performance of the network slice is, and the network performance can be better ensured. Therefore, if the available load of a network slice is lower than a certain threshold, such as the first available load threshold mentioned above, the performance of the network slice is poor. In the network slices used by the UE, the greater the number of network slices with poor performance, the worse the network performance, so that the ratio of the number of network slices with poor performance in the network slices used by the UE to the total number of network slices used by the UE can well reflect the network performance, and when the ratio exceeds a preset ratio, i.e., the network performance is poor, the target secondary cell is activated to improve the network performance.
In a possible implementation manner, obtaining a maximum data transmission amount of a network slice used by a UE, an actual data transmission amount of the network slice used by the UE, and an amount of data to be transmitted of the network slice used by the UE includes: determining the maximum data transmission amount of a network slice according to the maximum data transmission amount of a logical channel of Guaranteed Bit Rate (GBR) service established on the network slice and the maximum data transmission amount of a logical channel of non-guaranteed bit rate (NGBR) service established on the network slice. And determining the actual data transmission quantity of the network slice according to the actual data transmission quantity of the logical channel of the GBR service established on the network slice and the actual transmission rate of the logical channel of the NGBR service established on the network slice. And determining the data volume to be transmitted of the network slice according to the data volume to be transmitted of the logical channel of the GBR service established on the network slice and the data volume to be transmitted of the logical channel of the NGBR service established on the network slice.
Services established on a network slice used by the UE can be classified into two types, one type is GBR service, where GBR service refers to a service that a system guarantees a minimum bit rate of a service bearer, and the bit rate can be maintained even when network resources are in short, such as real-time services like voice call and video call. One is an NGBR service, wherein the NGBR service refers to a service that needs to reduce a bit rate under a situation that network resources are in a shortage, for example, a service such as web browsing. Therefore, according to the maximum data transmission quantity of the NGBR service and the GBR service on the network slice, the maximum data transmission quantity of the network slice can be obtained more accurately, and similarly, the actual data transmission quantity and the data quantity to be transmitted of the network slice can be obtained more accurately.

In one possible implementation, if a ratio of the number of the first target network slices to the total number of network slices used by the UE is greater than a preset ratio, activating the target secondary cell includes: if the ratio of the number of the first target network slices to the total number of the network slices used by the UE is greater than a preset ratio, determining the available load of the first target network slices in the configured but inactive secondary cell. Then, if the available load of the first target network slice in the configured but inactive secondary cell is greater than a second available load threshold, the first target network slice is determined to be a second target network slice.

Therefore, through the above process, the active target secondary cell can be determined based on the available load of the second target network slice, so that the network performance is improved after the mutual interference between the network slice technology and the carrier aggregation technology is reduced.

Detailed Description
The terms "first," "second," and "third," etc. in the description and claims of this application and the above-described drawings are used for distinguishing between different objects and not for limiting a particular order.
In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. 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 relevant concepts in a concrete fashion for ease of understanding.
In the description of the present application, a "/" indicates a relationship in which the objects associated before and after are an "or", for example, a/B may indicate a or B; in the present application, "and/or" is only an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. Also, in the description of the present application, "a plurality" means two or more than two unless otherwise specified. "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 5G system inherits the key technology in the LTE-A system, namely the aggregation carrier technology, and introduces the network slicing technology. The carrier aggregation technique and the network slicing technique are respectively introduced as follows:
carrier aggregation: in order to meet the requirement of peak rate per user and system capacity increase, the LTE-a system provides a technology for increasing transmission bandwidth, i.e., Carrier Aggregation (CA). CA is a system that aggregates multiple carrier units (CCs) to support a larger transmission bandwidth, thereby effectively increasing uplink and downlink transmission rates. Generally, each CC corresponds to an independent cell, and in a CA scenario, the cell corresponding to the CC may be followed by a primary cell (PCell) and a secondary cell (SCell).
Wherein, the PCell is a cell operating on a primary frequency band. The UE performs an initial connection establishment procedure or starts a connection re-establishment procedure in the cell. During the re-handover, the cell is indicated as the primary cell. An SCell is a cell operating on a secondary frequency band, which may be configured to provide additional radio resources for a UE once the SCell establishes an RRC connection with the UE. If the UE in the RRC connected state is not in the CA scenario, the UE has only one serving cell (serving cell), i.e., PCell; if the UE is in the CA scenario in the RRC connected state, the UE has multiple serving cells, where the multiple serving cells include a PCell and an SCell.
The CA is mainly used for managing the secondary carrier, including configuring the secondary carrier, de-configuring the secondary carrier, activating the secondary carrier, deactivating the secondary carrier, and the like. For whether the secondary carrier is configured and activated, the UE in the CA may be in three states, that is, configured but not activated, configured and activated, and not configured. In one possible implementation, the CA mainly performs carrier management through a Radio Resource Control (RRC) signaling and a media access control address (MAC) layer control unit.
In the prior art, after configuring an auxiliary carrier to a UE in a CA scenario, the auxiliary carrier is in an inactive state by default, and the UE cannot transfer resources of multiple carriers for data transmission. The UE may be provided with resources for scheduling only after a secondary carrier is activated by a transmission MAC layer Control Element (CE), and may transmit data on the secondary carrier and a primary carrier simultaneously. There are three ways for activating the secondary carrier, and the three ways for activating the secondary carrier are described below:
1. when the service volume, namely the service rate, the service delay and the like reach a certain threshold value, the auxiliary carrier is activated so as to achieve the purposes of increasing air interface resources and meeting service requirements.
2. When the secondary carrier is used, the spectrum efficiency of the secondary carrier needs to be considered, and therefore, the secondary carrier can be activated based on the channel quality. And if the channel quality of the SCC is better, activating the secondary carrier.
3. Blind activation. And activating the secondary carrier after the configuration of the secondary carrier is completed so as to improve the service rate. However, after the secondary carrier is activated, the UE needs to monitor a physical downlink control channel (PDUCCH) for the activated secondary carrier, and thus, power consumption of the UE may increase.
In a possible implementation manner, whether to activate the secondary carrier is determined according to values of parameters including at least one of a Radio Link Control (RLC) first packet latency, a data transmission duration, and a Physical Resource Block (PRB) utilization. The data caching length refers to the data quantity in the user caching queue obtained through evaluation, and if the data quantity is larger than a specific threshold value, the activation process of the auxiliary carrier is triggered; the RLC first packet waiting time delay is the transmission time length of the preamble data volume in the user cache queue obtained by value evaluation, and if the RLC first packet waiting time delay is larger than a specific threshold value, an auxiliary carrier activation process is triggered; the data transmission duration refers to the estimated transmission duration of the data obtained by estimation according to the data cache length and the current system resource use condition, and if the data transmission duration is greater than a specific threshold value, an auxiliary carrier activation process is triggered; the PRB utilization rate is generally not used alone, but used as a pre-activation condition for parameters such as data buffer length and RLC first packet waiting time delay, for example, after it is determined that the PRB utilization rate reaches a certain threshold, it is determined that the data buffer duration is greater than a corresponding threshold and the RLC first packet waiting time delay is greater than a corresponding threshold, and then an activation process of the secondary carrier is triggered.
Since the secondary carrier corresponds to the secondary cell PCell, the activation process of the secondary carrier, i.e., the activation process of the secondary cell, is described in the following description as the activation process of the secondary cell in a unified manner.
Network slicing: network slicing is a new technology introduced in a 5G system, and may be understood as a set of logical network functions supporting communication service requirements of a specific usage scenario or business model, which are implemented based on physical infrastructure, and these logical network functions may be regarded as a series of sub-functions (NSFs) decomposed by Network Functions (NFs) under a 5G core (5G core, 5 GC). That is, the network slice is an end-to-end solution, and the end-to-end solution can be applied not only to a core network but also to a Radio Access Network (RAN). The network slice realizes end-to-end logic network division according to specific scenes and requirements of services, and configures network resources as required.
Wireless sub-slice awareness may be understood as it taking different traffic handling approaches for different slices. With the diversification of future services and access scenes, the sub-slices of the RAN are required to have the characteristics of flexible open deployment and network slice sensing capability capable of flexibly allocating wireless resources as required so as to support resource isolation among network slices based on services.
The basic granularity of a network slice is a Protocol Data Unit (PDU) Session (Session), one network slice used by the UE may include 1 or more PDU sessions (i.e., one or more services are established on one network slice used by the UE), and one PDU Session may include multiple logical channels. The UE transmits uplink or downlink data, i.e. service data, on the logical channel. The UE may transmit service data of one or more services on the same logical channel, that is, the same logical channel corresponds to one or more services. Generally, the number of logical channels used by the UE is at most 12. The core network can establish a plurality of network slices, a plurality of PDU sessions and a plurality of logical channels for one UE according to service requirements.

Wherein, the service data of a and b are transmitted on the logical channel with the index value of 2, the service data of c is transmitted on the logical channel with the index value of 4, and the actual data transmission quantity of the network slice is

In a possible implementation manner, the data volume to be transmitted of the network slice is determined according to the data volume to be transmitted of the logical channel of the GBR service established on the network slice and the data volume to be transmitted of the logical channel of the NGBR service established on the network slice.
In particular, according to
Figure BDA0002733390570000094
And determining the data volume to be transmitted of the network slice. Wherein, Bbuffer_slice_iIndicating the amount of data to be transmitted of the ith (i is an integer greater than or equal to 0) network slice used by the UE, BOGBR_idRepresenting the amount of data to be transmitted on a logical channel with an index value of GBR _ id, BONGBR_idRepresenting the amount of data to be transmitted on a logical channel with an index value of NGBR _ id, GGBR_idRepresentation BOGBR_idCorresponding fifth predetermined coefficient, GNGBR_idRepresentation BONGBR_idCorresponding sixth predetermined coefficient. For the expressions of GBR _ id, NGBR _ id, NumGbrRB, NumNGbrRB, reference is made to the above, and details thereof are not repeated herein.
Illustratively, the index value of the logical channel of the GBR service established on the network slice ranges from 0 to 12, and the index value of the logical channel of the NGBR service established on the network slice ranges from 0 to 12. Taking the above-mentioned determination of the amount of data to be transmitted of the 1 st network slice used by the UE as an example, only 3 NGBR services, that is, NGBR service d, GBR service e, and GBR service f, are established on the network slice. Wherein, the service data of e and f are transmitted on the logical channel with the index value of 8, the service data of d are transmitted on the logical channel with the index value of 7, and the data volume to be transmitted of the network slice is

It should be noted that, services established on a network slice used by the UE may be classified into two types, one type is GBR service, where GBR service refers to a service that a system guarantees a minimum bit rate of a service bearer, and even under a situation of a shortage of network resources, the bit rate can also be maintained, for example, real-time services such as voice call, video call, and the like. One is an NGBR service, wherein the NGBR service refers to a service that needs to reduce a bit rate under a situation that network resources are in a shortage, for example, a service such as web browsing. Therefore, according to the maximum data transmission quantity of the NGBR service and the GBR service on the network slice, the maximum data transmission quantity of the network slice can be obtained more accurately, and similarly, the actual data transmission quantity and the data quantity to be transmitted of the network slice can be obtained more accurately.
Optionally, the difference between the maximum data transmission amount of the network slice used by the UE and the actual data transmission amount and the data amount to be transmitted is determined as the available load of the network slice. If the available load of the network slice used by the UE is less than the first available load threshold, the network slice is determined to be the first target network slice.
It should be noted that the first preset coefficient, the second preset coefficient, the third preset coefficient, the fourth preset coefficient, the fifth preset coefficient, and the sixth preset coefficient are predetermined and may be adjusted according to actual needs. The first preset coefficient, the third preset coefficient and the fifth preset coefficient may be the same or different, and the second preset coefficient, the fourth preset coefficient and the sixth preset coefficient may be the same or different.
S302, whether the secondary cell is activated or not is determined.
Optionally, if the ratio of the number of the first target network slices to the total number of the network slices used by the UE is greater than a preset ratio, the target secondary cell is activated.
In a possible implementation manner, after determining that a ratio of the number of the first target network slices to the total number of the network slices used by the UE is greater than a preset ratio, recording an identifier of the first target network slice, and determining available loads of the first target network slices in different secondary cells, where the different secondary cells are secondary cells configured for the UE but not activated. Then, if the available load of the first network slice in the configured but inactive secondary cell is greater than a second available load threshold, the first target network slice is determined to be a second target network slice. That is, the second target network slice has a correspondence with the secondary cell. And finally, determining the configured but inactivated secondary cells with the number of the second target network slices larger than the preset number threshold as target secondary cells, and activating the target secondary cells.
Illustratively, taking as an example that the non-activated secondary cells configured to the UE include secondary cell 1 and secondary cell 2, the first target network slice includes network slice 1, network slice 2, and network slice 3. The available load of the network slice 1 in the secondary cell 1 is a, the available load of the network slice 2 in the secondary cell 1 is b, the available load of the network slice 3 in the secondary cell 1 is c, the available load of the network slice 1 in the secondary cell 2 is d, the available load of the network slice 2 in the secondary cell 2 is e, and the available load of the network slice 3 in the secondary cell 2 is f. If the second available load threshold is g, a > g > b > c, d > e > g > f for secondary cell 1 and secondary cell 2, the second target network slice comprises network slice 1 for secondary cell 1 and network slice 2 for secondary cell 2. If the preset number threshold is 1, the number of the second target network slices of the secondary cell 2 is 2, the number of the second target network slices of the secondary cell 1 is 1, and only the number of the second target network slices of the secondary cell 2 is greater than the preset number threshold. Therefore, the secondary cell 2 is determined as a target secondary cell, and the target secondary cell is activated.
In a possible implementation manner, if there are multiple target secondary cells, determining a maximum value of available loads of the second target network slice in all the target secondary cells, and activating the target secondary cell corresponding to the maximum value.
For example, in the above example, the secondary cell 1 and the secondary cell 2 are both target secondary cells, and if the preset number threshold is 0, the secondary cell 1 and the secondary cell 2 are both target secondary cells. The second target network slice with the largest available load corresponding to the secondary cell 1 is the network slice 1, and the second target network slice with the largest available load corresponding to the secondary cell 2 is the network slice 1. The available load of network slice 1 in secondary cell 1 is a and the available load of network slice 1 in secondary cell 2 is d. If a is larger than d, the maximum value of the available load of the second network slice in all the target secondary cells can be determined to be a, so that the corresponding secondary cell, namely the secondary cell 1, when the value of the available load is a is determined to be the target secondary cell to be activated, and the activation is performed.
In the process, whether the target auxiliary cell is activated or not is determined based on the available load of the network slice, so that the effect of activating the auxiliary cell based on the network slice is realized, the mutual interference of a network slice technology and a carrier aggregation technology during resource allocation is reduced, and the effect of resource allocation is ensured. The larger the available load of the network slice is, the better the performance of the network slice is, and the network performance can be better ensured. Therefore, by using the ratio of the number of network slices with the available load larger than the first available load threshold to the total number of network slices used by the UE, the current network performance can be well determined, and the target secondary cell is activated to improve the network performance under the condition that the network performance is poor, that is, the ratio is larger than the preset ratio.
