Description
Technical Field
The present invention relates to the field of wireless technologies, and in particular, to a wireless resource allocation method and a network element device.
Background
In a 5G mobile communication Network, network Slice (Network Slice) refers to a complete logical Network consisting of a set of Network functions and associated required resources for providing specific Network capabilities and Network characteristics. The terminal, the base station and the core network interact through network slice selection auxiliary information (Network Slice Selection Assistance Information, NSSAI) to realize the processes of establishing, selecting, changing and the like of slices, and different slices are carried by different protocol data unit sessions (Protocol Data Unit session, PDU sessions).
To adapt to diversified traffic demands, 5G mobile communication networks provide quality of service (Quality of Service flow, qoS) management mechanisms based on quality of service flows (Quality of Service flow, qoS flows). QoS flow is the finest granularity of QoS differentiation processing within a PDU session (PDU session), uniquely identified by a QoS flow address (QFI).
According to 3GPP standards TS23.501 and TS38.300, existing 5G QoS mechanisms follow an allocation and reservation priority (Allocation and Retention Priority, ARP) parameter as a priority indication for QoS flow allocation resources, which identifies the priority order in which data radio bearers (data radio bearer, DRBs) are allocated for QoS flows and released for which DRBs are occupied by the parameters by calibrating ARP values for the QoS flows. ARP is included as one of the QoS parameters in the QoS profile, provided by the 5G core network (5 GC) to the 5G access network (NG-RAN).
Because the resource allocation of QoS flow is performed in PDU session, ARP mechanism only works in PDU session, and different network slices are carried by different PDU session, which are nested, for QoS flow belonging to different network slices (correspondingly belonging to different PDU session) and having the same ARP value, there is no priority difference in DRB allocation. For example, compared to the online video traffic slice 1, the remote driving video backhaul slice 2 needs to allocate radio resources preferentially, and traffic flows of both traffic flows are classified as QoS flow 2 (QoS flow id=2) and have the same ARP under the existing QoS mechanism, and are treated equally when allocating resources, so that the allocation of radio resources at the network slice level cannot be achieved.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The network implementation architecture may be applied in a 5G network, and referring to fig. 1, the network implementation architecture includes a user terminal 10, a network node device 20, a core network unit 30, and a network management unit 40. In practical application, the connection between the devices may be wireless connection, and for convenience and intuitionistic representation of the connection relationship between the devices, a solid line is used for illustration in fig. 1.
The network node device 20 may be a base station, which may be a commonly used base station, an evolved node b (evolved node base station, eNB), a network side device in a 5G system (e.g., a next generation base station (next generation node base station, gNB) or a transmitting and receiving point (transmission and reception point, TRP)) or a cell.
It will be appreciated that the user terminal 10, the network node device 20, the core network unit 30 and the network management unit 40 comprised in the above described network implementation architecture may each be formed as one network element device in a wireless transmission network.
According to the wireless resource allocation method, the problem that wireless resource allocation in the prior art cannot be divided by the priority of the network slice level can be solved by acquiring the priority configuration information of the network slice and taking the priority configuration information of the network slice as the first allocation reference rule when wireless resource allocation is carried out.
As shown in fig. 2, one implementation manner of the radio resource allocation method in the embodiment of the present invention includes:

Specifically, in step S210, the acquired priority configuration information of the network slice is used to indicate the priority level of the network slice, specifically, the priority level may be the priority level when the DRB resource is allocated as the quality of service flow. When radio resource allocation is performed, the quality of service flow of the network slice with higher priority is prioritized over the quality of service flow of the network slice with lower priority.
In step S220, the first allocation reference rule is the highest allocation reference rule when performing radio resource allocation, and the priority of the other allocation reference rules is lower than the priority configuration information of the network slice.
In addition, in step S210, in the step of obtaining the priority configuration information of the network slice, the priority configuration information is obtained by means of a standard protocol predetermined, terminal transmission, core network unit transmission, and/or network management unit transmission.

when the priority level configuration information of the network slice is obtained through the mode of sending by the core network unit, the priority level configuration information sent by the core network is obtained through the NG interface message.
Specifically, when the priority configuration information of the network slice is acquired in a manner predetermined by the standard protocol, an absolute value of the priority level of each network slice set in the standard protocol may be obtained, and when the priority configuration information is acquired in a manner of terminal transmission, core network unit transmission and/or network management unit transmission, the acquired priority configuration information may be a relative value of the priority levels of a plurality of network slices transmitted by the terminal, core network unit or network management unit.
The specific configuration and the obtaining manner of the priority configuration information of the network slice may be determined according to a specific flow in the wireless network transmission, which is not illustrated herein.
Further, in step S210, in the step of obtaining the priority configuration information of the network slice, the obtained priority configuration information corresponds to the corresponding network slice identifier through a mapping relationship table; or the priority configuration information is part of a network slice identity.
Wherein the network slice identity may be S-nsai, and when the priority configuration information is part of the network slice identity (e.g., S-nsai), the network slice identity may be an n-bit in a slice differentiator (Slice Differentiator, SD).

For example, the number of the cells to be processed, priority level configuration information indicates the priority level of the network slice as "1, 2, 3...n", the higher the number of priority level configuration information, the higher the priority level, or the lower the number of priority level configuration information, the lower the priority level, in particular in a predetermined manner.

and taking the allocation and reservation priority ARP parameter as a second allocation reference rule of wireless resource allocation, and allocating DRB resources for the service quality stream.
In the embodiment of the present invention, in step S220, the step of allocating data radio bearer DRB resources for a quality of service flow by using the priority configuration information as a first allocation reference rule for radio resource allocation includes:
when the priority level of the priority level configuration information of the network slice corresponding to the first quality of service flow is higher than the priority level of the priority level configuration information of the network slice corresponding to the second quality of service flow, the DRB resource is preferentially allocated to the first quality of service flow.
Optionally, in step S220, the step of allocating data radio bearer DRB resources for the quality of service flow with the priority configuration information as a first allocation reference rule of radio resource allocation includes:

It should be noted that, the specific manner of allocating the data radio bearer DRB resource to the qos flow by using the priority configuration information as the first allocation reference rule of the radio resource allocation is not limited to the two manners, and may be specifically determined according to the specific implementation flow of the radio resource allocation.
