Description

Configuration method, device and equipment of radio bearer and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a computer-readable storage medium for configuring a radio bearer.

Background

Devices and devices in close proximity to each other allow direct communication between the devices. For convenience of description, a link for direct communication between terminals is defined as a Sidelink (direct link), and a corresponding wireless interface is referred to as a direct communication interface (also referred to as a Sidelink interface); the cellular communication link between the network and the direct communication device is called a uulink, and its corresponding interface is called a Uu interface.

The devices that communicate directly may also all be on-line or off-line, or some may be on-line and some off-line. So-called on-net, i.e. devices participating in direct communication are located within 3GPP (3rd Generation Partnership Project) direct communication carrier coverage, and so-called off-net, i.e. devices participating in direct communication are not within 3GPP direct communication carrier coverage.

In LTE (Long Term Evolution), a terminal establishes a direct communication interface bearer and performs direct communication interface bearer configuration by itself, and the network does not need any participation at all. For the on-network terminal, if the terminal wants to acquire the direct communication interface resource, it needs to send a resource request signaling to the network side after completing the SLRB (Sidelink Radio Bearer) configuration. Therefore, in the LTE system, the time from bearer establishment to resource acquisition is relatively long, thereby affecting the transmission delay of the service.

Specifically, the terminal determines that the SLRB needs to be established if the mapping relationship between the QoS Flow and the SLRB is not established when the access network protocol layer of the terminal receives the first data packet corresponding to the high-level QoS Flow or when the access network protocol layer of the terminal receives the indication information that the high-level QoS Flow arrives.

Or, in the case that the resource allocation information includes only the resource allocation mode corresponding to the SLRB and the resource allocation mode is a resource allocation mode scheduled by the network, the network-side device may further send configuration information of a pre-configured resource to the terminal according to the auxiliary information sent by the terminal.

And the network side equipment receives the SLRB configuration request message, replies the SLRB configuration message to the terminal and performs SLRB configuration for the terminal through the SLRB configuration message. The SLRB configuration message at least needs to carry resource allocation information. The resource allocation information includes a resource allocation mode corresponding to the SLRB.

Further, the resource allocation information may be based on RAT configuration or based on configuration frequency points or based on BWP configuration.

Step 404, the terminal establishes the SLRB.

Step 405, the terminal judges whether the pre-configured resource auxiliary information reporting triggering condition is met.

This step is an optional step. Step 405 and 407 need only be performed when a certain service of the terminal needs to use the configured resource.

If the resource allocation information in step 403 is the resource allocation mode corresponding to the SLRB, and the resource allocation mode configured by the network side device for the terminal is the resource allocation mode scheduled by the network, if a certain service of the terminal needs to use the pre-configured resource, it is determined that the pre-configured resource-related auxiliary information reporting trigger condition is satisfied. The terminal needs to further send the auxiliary information to the network side device.

Step 406, the terminal reports the preconfigured resource auxiliary information to the network side device.

This step is an optional step. The content of the auxiliary information includes at least but is not limited to: traffic characteristics of the SLRB, including but not limited to: period, packet size, packet arrival interval.

Step 407, the network side device sends the pre-configured resource configuration information to the terminal.

This step is an optional step. After receiving the auxiliary information, the network side device may further configure a pre-configured resource for the terminal. Wherein, the configuration information of the pre-configured resource includes but is not limited to one or a combination of the following:

pre-configuring the number of the resource;

And step 408, the terminal sends the direct communication interface data.

In another embodiment of the present invention, the steps 401-402 are also optional.
