Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a wireless bearer processing method, network equipment, terminal, device and storage medium. Background Art

[0002] Extended Reality (XR) includes three representative forms: Augmented Reality (AR), Mixed Reality (MR) and Virtual Reliability (VR). XR refers to a combination of real and virtual environments that can be interacted with by humans and machines, created through computer technology and wearable devices.

[0003] XR services support multi-modality. Multi-modality includes intra-UE multi-modality and inter-UE multi-modality. In intra-UE multi-modality, all user devices are connected to one UE, and the XR service accesses the wireless network through the UE. It is necessary to implement synchronous transmission (also called collaborative transmission) of different quality of service (QoS) flows in an XR service by the same UE. In inter-UE multi-modality, different user devices access the wireless network as different terminals, and it is necessary to implement synchronous transmission of different QoS flows in an XR service by multiple UEs.

[0004] The Uu interface is used to transmit uplink and downlink data and / or control information between the terminal and the network device. In a multi-modal scenario, it is necessary to consider how to avoid transmission desynchronization between different QoS Flows corresponding to multi-modal services. Summary of the invention

[0114] In order to better describe the technical solutions in the embodiments of the present application, relevant knowledge is introduced below.

[0115] (1) Cellular network communication

[0116] Figure 1 It is a schematic diagram of the architecture of cellular network communication provided by related technologies, such as Figure 1 As shown, in the Long Term Evolution (LTE) system, traditional wireless communication adopts a cellular network communication mode, that is, the terminal and the network device transmit uplink and downlink data and / or control information through the Uu interface.

[0117] (2)Direct communication

[0118] Figure 2 is a schematic diagram of the architecture of direct communication provided by related technologies, such as Figure 2 As shown, in a device-to-device (D2D) or direct communication scenario, adjacent terminals can transmit data in a short range through a direct communication link (also called Sidelink or PC5). The wireless interface corresponding to the direct communication link is called a direct communication interface (also called Sidelink interface or PC5 interface).

[0119] (3) XR business

[0120] In the 3rd Generation Partnership Project (3GPP) 5G system, XR services are introduced. XR services are divided into the following three types:

[0121] ① Augmented reality (AR) seamlessly integrates the real world and the virtual world, creating a half-real and half-fake experience;

[0122] ② Virtual reality VR uses equipment to simulate a virtual world, which is completely fake;

[0123] ③Mixed reality MR, which contains both real physical entities and virtual information.

[0124] XR services support multi-modality. In a multi-modal scenario, multiple service traffic flows of a service need to be coordinated during air interface transmission, and this coordinated transmission has certain synchronization requirements. XR services can have many user devices, such as 3D glasses, handle remote controls, etc. There are two basic ways to connect XR services to wireless networks:

[0125] Mode 1: All user devices are connected to one terminal, and the XR service accesses the wireless network through the terminal. In this mode, the same terminal is required to achieve synchronous transmission (also called collaborative transmission) of different QoS Flows in an XR service, also known as Intra-UE Multi-modal.

[0126] Mode 2: Different user devices access the wireless network as different terminals, and XR services access the wireless network through different terminals. In this mode, multiple terminals need to synchronize different QoS flows in one XR service, which is also called Inter-UE Multi-modal.

[0127] For mode 2, different terminals may use a direct communication interface for communication connection and information exchange.

[0128] However, for terminals using multimodal XR services, if a Uu link failure occurs, how to handle it is an urgent problem to be solved.

[0129] In view of the above-mentioned problems existing in the related art, the embodiments of the present application provide a wireless bearer processing method, network equipment, terminal, apparatus and storage medium.

[0130] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0131] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0132] In the embodiments of the present application, "determine B based on A" means that the factor A should be considered when determining B. It is not limited to "B can be determined based on A alone", but should also include: "determine B based on A and C", "determine B based on A, C and E", "determine C based on A, and further determine B based on C", etc. In addition, it can also include taking A as a condition for determining B, for example, "when A meets the first condition, use the first method to determine B"; for another example, "when A meets the second condition, determine B", etc.; for another example, "when A meets the third condition, determine B based on the first parameter", etc. Of course, it can also be a condition that takes A as a factor in determining B, for example, "when A meets the first condition, use the first method to determine C, and further determine B based on C", etc.

[0296] Similarly, if the failure occurs in SCG, the RB carried by SCG is associated with the RB carried by MCG, or the RB carried by SCG is associated with the RB of other terminals belonging to network device 1, then network device 1 is triggered to execute step 4.

[0297] If the network device 1 determines that the Uu link failure occurs in the terminal 1, and the terminal 1 has an RB association relationship with the terminal 2 belonging to the network device 2, the network device 1 is triggered to execute step 3.

[0298] Step 3: Network device 1 sends indication information 1 to network device 2.

[0299] Network device 1 sends indication information 1 to network device 2 through the interface between network devices. Indication information 1 is used to indicate that a Uu link failure occurs in terminal 1 served by network device 1 that is associated with terminal 2 served by network device 2, or to indicate the terminal identifier and RB identifier corresponding to the RB that needs to be suspended or released.

[0312] ③The network device determines that SCG failure occurs at terminal A.

[0313] ④The network device determines that MCG failure occurs at terminal A.

[0314] If the failure occurs in MCG, and the RB carried by MCG is associated with the RB carried by other SCGs, or the RB carried by MCG is associated with the RB of other terminals belonging to the network device, the network device is triggered to execute step 4.

[0315] Similarly, if the failure occurs in SCG, the RB carried by SCG is associated with the RB carried by MCG, or the RB carried by SCG is associated with the RB of other terminals belonging to the network device, the network device is triggered to execute step 4.

[0316] Step 3: The network device sends indication information to terminal A and / or other terminals to which RBs associated with RBs carried on the failed Uu link of terminal A belong.

[0317] The indication information is used to instruct terminal A and other terminals to suspend or release one or more RBs (RBs associated with RBs transmitted on the cell group where the failure occurs).
