technical field

Background technique

This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section.

Network slicing is a relatively new concept in wireless communications. The concept of network slicing in the core network has reached a certain degree of consensus in the industry. Network slicing of the core network refers to the realization of customized network requirements after selecting and combining different network function modules according to the characteristics of business and service requirements.

For a wireless network, the wireless network provides a wireless signal coverage service, and the sending and receiving of the wireless signal is implemented by a relatively fixed RRU (Radio Remote Unit, radio frequency remote unit). Analogous to the core network, the coverage communication capability provided by the wireless network is also a business requirement. Users can request operators to customize different coverage networks according to their own wireless coverage requirements to achieve special services.

A network slice instance is a logical concept in the sense of network operation. Different network slice instances face different user customization requirements or network deployment requirements. Different network slice instances have different functions and resources, and different network slice instances can share some functions and resources. , can monopolize all resources in extreme cases. Currently, the access network can select a core network supporting the network slice for the user equipment (UE) according to the network slice selection assistance information (NSSAI). On the core network side, network slices can be isolated through PDU (Protocol Data Unit, Protocol Data Unit) Session (session). Each PDU session can only belong to a certain network slice, and two network slices cannot use the same PDU session. However, on the access network side, the base station cannot identify the correspondence between QoS (Quality of Service) flows, radio bearers, and network slices, so the access network side cannot implement logical isolation of network slice resources.

Detailed ways

In order to implement logical isolation of different network slice resources on the radio access network and the UE side for network slicing application scenarios, embodiments of the present invention provide a data transmission configuration and a data transmission method and device.

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention, and in the absence of conflict, the present invention The embodiments and the features in the embodiments can be combined with each other.

Using an example to better understand the embodiment of the present invention, the following briefly introduces QoS and wireless data bearer in a wireless communication network.

A wireless communication network (for example, an LTE network, which is described below using the LTE network as an example) is a data network on which various services (such as Internet browsing, voice, online games, etc.) are carried. Due to different service characteristics and requirements (for example: different services are sensitive to delay, different requirements for transmission bandwidth, etc.), it is required that the LTE network can provide QoS services for different services and users.

In an LTE network, the core network (EPS) and the radio side (eNB) play different roles in the QoS process. In general, some active constraints and settings related to QoS are more carried out on the core network side (such as the setting of user subscription rate, service priority of user bearer, etc.); Network strategy: According to the QoS parameters sent by the core network, the resources on the wireless side are scheduled.

During the process of UE attaching to the LTE network, it is necessary to create an EPS (Evolved Packet System) bearer (UE-eNB-S-GW (Service Gateway)-P- GW). Each UE can have multiple bearers, and the number depends on the services it uses (for example: web browsing, IPTV, voice, etc.) and the strategies adopted by operators for different services. If the UE uses multiple services (such as accessing multiple websites), from the P-GW side, there are multiple IP data flows (IPflow), and the P-GW needs to map these IP flows to SDF (Service Data Flow, service data flow), and then mapped to the bearer after SDF-level QoS processing, and delivered to the UE. After P-GW mapping, bearer-level QoS processing is performed inside the LTE network.

In EPS, the basic unit of QoS control is bearer. The service data flows mapped to the same EPS bearer will get the same QoS guarantee (such as scheduling strategy, radio bearer strategy, etc.). If it is desired to provide different QoS for two SDFs (Service Data Flow, service data flow), the two SDFs need to establish different EPS bearers respectively.

Based on this, an embodiment of the present invention provides a data transmission configuration method, as shown in FIG. 1 , which may include the following steps:

S11. For the service data flow to be transmitted, determine a QoS policy and a network slice corresponding to the service data flow.

S12. Add a network slice identifier to the service data flow according to the network slice corresponding to the service data flow.

Wherein, the network slice identifier is used to instruct the wireless access network device to determine the network slice corresponding to the service data flow to be transmitted according to the network slice identifier to allocate wireless transmission resources for the service data flow to be transmitted, so as to The wireless transmission resources of the slice are isolated; and the network slice identifier is used to instruct the user equipment UE to map the received service data flow to a corresponding network slice according to the network slice identifier when receiving the service data flow for processing, In order to isolate the processing resources of different network slices.

S13. According to the determined QoS policy, map the service data flow added with the network slice identifier to the wireless data bearer established according to the QoS policy for transmission.

As shown in FIG. 2 , in order to facilitate the isolation of access network slice resources, the embodiment of the present invention introduces management of end-to-end (E2E service) network slices based on Qos flows. Among them, NG-RAN is a wireless access network based on next-generation cloud computing, NG-CN is a core network based on cloud computing, NR (New Radio, new air interface) Node (base station), and Radio Bearer refers to wireless bearer.

In the case that network slice services have multiple Qos requirements, the embodiments of the present invention propose a management method based on Qos flow groups. Figure 2 shows the network slicing model after Qos processing. There may be multiple PDU sessions in the network slice, and there may be multiple Qos flows in each PDU session, and these Qos flows are finally mapped to radio bearers for transmission.

In order to enable radio access network devices and UEs to distinguish service data streams from different network slices to logically isolate corresponding radio transmission resources or terminal processing resources, in the embodiment of the present invention, on the core network side, according to The network slice corresponding to the service data flow adds a network slice identifier to the service data flow. Specifically, in the embodiment of the present invention, the management of network slices is implemented by introducing QoS group marks. For multiple Qos flows (Qosflow) under the same network slice, a Qos flow group (Qos flow group) is formed. For the same network slice, it may have multiple Qosflows. Although these Qos flows correspond to different Qos flow ids (QoS flow identifiers), these Qos flows should have the same network slice Qos group (Qos flow group id, QoS flow group identifier) to indicate that this group of Qos flows corresponds to the same network slice. Both the UE side and the RAN (Radio Access Network) side need to maintain Qosflow group identifiers corresponding to all Qos flows. Ensure that both UE and RAN can identify all Qos flows corresponding to network slices, and can distinguish Qos flows corresponding to different network slices. Wherein, the QoS flow involved in the embodiment of the present invention refers to a service data flow corresponding to a QoS policy.

Figure 3 shows the network slice management model diagram based on Qos group. The UE is connected to three network slices. The services of slice 1 (network slice 1) are transmitted through Qos flow 1, Qos flow 2 and Qos flow 3, which have the same Qosflow group id 1. The service of slice 2 is transmitted through QOS flow 2 and the slice is marked with Qos flow group 2. The service of slice 3 is transmitted through Qos flow 5 and Qos flow 6, and they have the same qos flowgroup id3. After the Qos flow is mapped to the DRB (radio data bearer), the UE receives data flows from each network slice through different DRBs, and maps them to different network slices through the Qos slice group id, thereby realizing end-to-end data isolation and logic Resource isolation.

Preferably, during specific implementation, in order to facilitate the radio access network side device to distinguish different network slices, in the embodiment of the present invention, the radio access network device may be notified of the network handover identifiers corresponding to different wireless data bearers in any of the following ways.

method one,

When mapping the service data flow for which the QoS policy is determined to the wireless data bearer, through the correspondence between the service data flow and the network slice determined in step S12, indirectly notify the wireless access network device of the transmission of the service data flow Correspondence between wireless data bearer and network slicing. Taking Figure 3 as an example, assuming that QoS Flow1 and QoS Flow2 are mapped to DRB1 for transmission according to the preset QoS policy, and the network slice identifier corresponding to QoS Flow1 and QoS Flow2 is group1, it can be determined that the network slice identifier corresponding to DRB1 is also group1 .

Method two,

Allocate new network slice identifiers for wireless data bearers, that is, for wireless data bearers corresponding to different network slices, the core network side reassigns network slice identifiers for wireless data bearers, so that radio access network devices can distinguish the network slice identifiers corresponding to different network slices. In this way, network slice resources can be isolated at the wireless data bearer granularity, and different network slices can be logically isolated when resource allocation and scheduling are performed on the access network.

Correspondingly, the embodiment of the present invention also provides a data transmission method respectively implemented by the radio access network side and the UE side, which will be introduced respectively below.

S42. According to the network slice identifier corresponding to the wireless data bearer, allocate wireless transmission resources for the service data flow to be transmitted, so as to isolate the wireless transmission resources of different network slices.

Preferably, the service data flow carries a network slice identifier, and the network slice identifier is added by the core network device to the service data flow according to the network slice corresponding to the service data flow. Based on this, the wireless interface The network access device may determine the network slice identifier corresponding to the wireless data bearer according to the following method: determine that the network slice identifier carried by the service data flow is the network slice identifier corresponding to the wireless data bearer.

Or, during specific implementation, the radio access network device may also receive the network slice identifier allocated by the core network device for the wireless data bearer. In this way, in step 42, the radio access network device may determine the network slice identifier corresponding to the wireless data bearer according to the network slice identifier allocated by the core network device for the wireless data bearer.

As shown in Figure 5, it is a schematic diagram of the implementation process of the data transmission method implemented by the UE side, which may include the following steps:
