Abstract

The present disclosure provides a method, an apparatus, a system and a base station for configuring radio resources, which relate to the technical field of wireless communication, and the method includes: and sending at least one configuration message corresponding to each network slice to the terminal, wherein each configuration message comprises an information unit which carries a plurality of data resources in the corresponding network slice to bear the same configuration parameters.

Description

Wireless resource allocation method, device and system and base station
Technical Field
The present disclosure relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, a system, and a base station for configuring a radio resource.
Background
Compared with a 4G network based on a bearer management mechanism, a 5G quality of service (QoS) mechanism adopts a more flexible two-level mapping mode. The core network side maps a plurality of IP flows with the same QoS requirement to the same QoS flow, the access network side maps the QoS flow to a Data Resource Bearer (DRB), and the DRB is used as the minimum granularity to schedule the wireless resource.
QoS mechanisms aim to classify and manage QoS flows of different QoS requirements on a given network. For example, current QoS architectures are able to distinguish one type of QoS flow (e.g., high definition video) from other types of QoS flow (web browsing). However, the current QoS architecture cannot differentiate and treat services with the same QoS requirements for different classes of users.
In addition, to ensure resource isolation and security of private networks, it is necessary to prevent data traffic in one private network from negatively impacting other private network services. For example, telemedicine related services should not be affected by mass data communication services.
For the above reasons, 5G defines the concept of network slicing. The network slice can divide a physical network of an operator into a plurality of virtual networks, so that the configuration and management of end-to-end personalized resources are realized, and an originally extensive pipeline is further refined. Each network slice provides a different level of quality of service such as rate, reliability, latency, etc.
On the access network side, for a DRB of a particular network slice, a specific configuration is often adopted to implement the service or the user type supported by the network slice. For example, a ultra-high reliable and low latency communication (URLLC) network slice employs the following configuration: packet Data Convergence Protocol (PDCP) repetition, radio link control unacknowledged mode (RLC UM), and shorter Transmission Time Interval (TTI).
Disclosure of Invention
In the related art, when configuring a DRB of a network slice, the DRBs are configured one by one, that is, one DRB is configured, and another DRB is configured. The inventors have noted that such an arrangement is inefficient.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
The embodiment of the disclosure provides a wireless resource configuration method, which includes: at least one configuration message corresponding to each network slice is transmitted to the terminal, and each configuration message includes an Information Element (IE). The information unit in each configuration message carries the same configuration parameters of a plurality of data resource bearers in the corresponding network slice.
Fig. 1 is a schematic diagram of an information unit, according to some embodiments of the present disclosure. As shown in fig. 1, the information unit carries a plurality of data resources carrying mutually same configuration parameters, such as PDCP configuration, RLC configuration, media Access Control (MAC) configuration, and the like. Different data resource bearers may be distinguished by a DRB identification (DRB ID).
The plurality of data resource bearers may be all data resource bearers in the network slice, or may be partial data resource bearers in the network slice. The configuration parameters that are the same as each other may be all configuration parameters of a certain data resource bearer, or may be partial configuration parameters of a certain data resource bearer.
In the above embodiment, the plurality of data resources of the same network slice carry the same configuration parameters to the information unit, and the configuration parameters are sent to the terminal. In such a way, when the data resource bearer is configured, the same parameters of the data resource bearer do not need to be configured repeatedly, and the configuration efficiency is improved. In addition, signaling overhead is also reduced.
In some implementations, the configuration message corresponding to each network slice may be one.
In other implementations, the configuration message corresponding to each network slice may be multiple, i.e., include multiple configuration messages. Here, the plurality of configuration messages may include a first configuration message and a second configuration message. The information unit in the first configuration message carries the configuration parameters that are the same as each other for the first group of data resource bearers in the corresponding network slice, and the information unit in the second configuration message carries the configuration parameters that are the same as each other for the second group of data resource bearers in the corresponding network slice. Here, the second set of data resource bearers and the first set of data resource bearers each include a plurality of data resource bearers, and the plurality of data resource bearers included in the two sets are at least partially different. For example, the second set of data resource bearers is partially the same as, and partially different from, the first set of data resource bearers. For another example, the second set of data resource bearers is completely different from the first set of data resource bearers, i.e. does not have one and the same data resource bearer.
In the foregoing implementation manner, for multiple groups of data resource bearers having the same configuration parameters in a network slice, the bearers are configured through different configuration information. Such an approach may further improve configuration efficiency.
In some embodiments, each configuration message is a radio resource control Connection Reconfiguration (RRC Connection Reconfiguration) message. In such a way, a new signaling message is not required to be introduced, and the signaling overhead is reduced.
In some embodiments, each configuration parameter includes a plurality of modifiable configuration items. In this way, configuration of different configuration parameters can be realized by using configuration messages with the same format, and the flexibility is higher.
In some embodiments, the configuration message corresponding to each network slice may be processed according to the service requirement. Here, the processing may include at least one of addition, modification, and deletion. When the service requirement changes, for example, the service requirement has a new requirement item, part of requirement items in the service requirement needs to be modified, or a requirement item in the service requirement needs to be deleted, the configuration message corresponding to the network slice may be correspondingly added, modified, and deleted.
Fig. 2 is a schematic diagram of information units corresponding to different network slices, according to some embodiments of the present disclosure.
For example, as shown in fig. 2, a network slice #1 may be set for three types of traffic, video, game, and web browsing: video, network slice #2: game, network slice #3: and browsing the webpage. For the three types of network slices, three information units related to the network slices can be generated respectively, so as to realize DRB configuration inside each network slice.

In such a manner, when the data resource bearer is configured, the same parameters of the data resource bearer do not need to be configured repeatedly, and the configuration efficiency is improved.
In some embodiments, the radio resource configuration apparatus further includes a processing module 302 configured to process the configuration message corresponding to each network slice. For example, the processing may include at least one of adding, modifying, and deleting.
