Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a data transmission method, apparatus, and storage medium.
Background
An NR (New Radio), radio protocol stack is divided into two planes: a user plane and a control plane. A User Plane (UP) protocol stack is a protocol cluster adopted by User data transmission, and a Control Plane (CP) protocol stack is a protocol cluster adopted by Control signaling transmission of a system. Compared with an LTE (long term evolution, long Time Evolution) protocol stack, the NR user plane is further provided with an SDAP (Service Data Adaptation Protocol ) layer, and the user plane protocols are as follows from top to bottom: SDAP layer, PDCP (Packet Data Convergence Protocol ) layer, RLC (Radio Link Control, radio link control) layer, MAC (Media Access Control, medium access control) layer, and PHY (physical) layer. The NR control plane protocol is almost identical to the LTE protocol stack, and is sequentially as follows from top to bottom: NAS (non-access stratum) layer, RRC (Radio Resource Control, radio resource control layer) layer, PDCP layer, RLC layer, MAC layer, PHY layer. The SDAP layer is mainly used for transmitting data of a user plane, realizing mapping between uplink and downlink data QoS (Quality of Service ) flows (flows) to RBs (Radio bearers), adding QFIs (QoS Flow Indicator, qoS Flow identifiers) into the uplink and downlink data flows, and completing mapping of Reflective QoS. According to existing protocol specifications, each time a QoS Flow is established or changed, the QoS parameters of the QoS Flow need to be configured by signaling. Moreover, after the core network starts the reflection mapping, the receiver is required to be configured by the corresponding signaling for the 5QI corresponding to each QoS Flow, and in the above process, additional signaling is required to be configured, thereby increasing the network signaling overhead.

In the embodiment of the invention, by pre-configuring the QoS parameters which can be indexed by QFI at the data transmission interface, the configured QoS parameters can be different for different services when the implementation is carried out. Thus, the data to be transmitted needs to carry the corresponding QFI, so that the data receiving end searches the corresponding QoS parameters according to the QFI and provides the service meeting the QoS requirement according to the searched QoS parameters.
Fig. 1 is a schematic diagram of an implementation flow of a data transmission method according to an embodiment of the present invention, including the following steps:
s11, when data to be transmitted are received, QFI corresponding to the data to be transmitted is obtained.
S12, searching the QoS parameters corresponding to the obtained QFI from the pre-configured corresponding relation between the QFI and the QoS parameters.
And S13, transmitting data to be transmitted according to the searched QoS parameters.
The following describes a specific implementation procedure of the embodiment of the present invention in connection with a transmission procedure of downlink data and uplink data, respectively. The data transmission method provided by the embodiment of the invention is suitable for data transmission between Ng interfaces or Xn interfaces, wherein the Ng interfaces are data transmission interfaces between a core network and a base station, and the Xn interfaces are data transmission interfaces between the base stations. In the specific implementation, the corresponding relation between QFI and QoS parameters can be preconfigured in NgAP or XnAP, so that when data transmission is carried out, the corresponding QoS parameters can be searched according to the configured corresponding relation and the corresponding QoS guarantee is provided for the service according to the QFI. For convenience of description, the following description will take data transmission of Ng interfaces as an example, where the data transmission flow between Xn interfaces is similar to the data transmission flow between Ng interfaces.
1. The data to be transmitted is downlink data.
For the Ng interface, the downlink data includes data transmitted by the core network to the base station. In the embodiment of the invention, no matter the existing QoS flow or the newly-built QoS flow, the Ng interface does not need to carry the QoS parameter configuration signaling corresponding to QFI any more, and the data can be directly transmitted on the selected QoS flow.
For downlink data transmitted to a base station by core network equipment, the core network firstly judges whether the identified QoS flow is a newly-built QoS flow according to QFI, specifically, whether the QFI exists in the QFI in the QoS flow which is recorded by the core network equipment and already carries data packets, if the QFI does not exist, the newly-built QoS flow is determined. According to the QFI, the core network device carries the data packet in the IP flow to the corresponding QoS flow, carries the QFI in an Ng interface transmission carrier (for example, GPT-U (GPRS tunneling protocol user plane packet)) and/or carries the QFI in the data packet transmitted in the QoS flow, and sends the data to be transmitted to the base station.
After receiving the data to be transmitted, the base station obtains the QFI from the data transmission interface, in this example, from the transmission bearer of the Ng interface and/or from the data packet of the QoS flow for transmitting the data to be transmitted. If the base station judges that the QOS flow corresponding to the QOS flow is a newly built QoS flow according to the QFI mark, the base station records the QFI, searches the corresponding QoS parameter according to the QFI, and establishes a new RB (radio bearer) to transmit data to be transmitted according to the searched QoS parameter; or selecting RBs meeting corresponding QoS requirements from the existing RBs to transmit data to be transmitted according to the searched QoS parameters.
If the core network device determines that the identified QoS flow is an existing QoS flow according to the QFI, that is, the core network device can find the QFI in the existing QFI of the QoS flow that has already carried the data packet, the core network device carries the data packet in the IP flow onto the QoS flow corresponding to the QFI, carries the QFI in an Ng interface transmission bearer (for example, a GPT-U (GPRS tunneling protocol user plane packet)) and/or carries the QFI in the data packet transmitted in the QoS flow, and sends the data to be transmitted to the base station.
After receiving the data to be transmitted from the QoS flow, the base station obtains the QFI from the data transmission interface, in this example, from the transmission bearer of the Ng interface and/or obtains the QFI from the data packet of the QoS flow for transmitting the data to be transmitted, and determines that the corresponding QoS flow is the existing QoS flow according to the QFI, and then transmits the data to be transmitted by using the RB used for transmitting the data in the QoS flow last time.
As shown in fig. 2, which is a schematic diagram of a data transmission flow between a core network device (CN) and a base station (gNB), the method includes the following steps:
s21, the CN receives data to be transmitted.
S22, the CN transmits data to be transmitted to the base station.
Specifically, the CN transmits data to be transmitted to the base station through PDU Session/Tunnel.
S23, the base station performs transmission processing on the data to be transmitted.
In the implementation, if the QFI is determined to be a new QoS flow, the corresponding QoS parameter is searched in the corresponding relation between the pre-configured QFI and the QoS parameter according to the QFI, and then a new radio bearer RB to be transmitted meeting the QoS requirement is established according to the searched QoS parameter, or an RB to be transmitted meeting the QoS requirement is selected from the existing RBs. If it is determined that there is a QoS flow according to QFI, the data to be transmitted is transmitted by using the RB used for last transmitting the data in the QoS flow.
2. The data to be transmitted is uplink data.
The base station receives data to be transmitted from the RB, analyzes the data to be transmitted to obtain QFI and a data load, loads the data load to QoS flow marked by the QFI, sends the data to be transmitted to core network equipment, and carries the QFI in the transmission load of a data transmission interface and/or carries the QFI in a data packet transmitted in the QoS flow. After receiving the data transmitted by the QoS flow, the core network equipment records the QFI if the QFI is determined to be a new QoS flow, and sends the data packet received from the QoS flow to an upper layer for processing, and if the QFI is determined to be an existing QoS flow, directly sends the data packet received from the QoS flow to the upper layer for processing.
As shown in fig. 3, which is a schematic flow chart of data transmission from a base station to a core network device, the method includes the following steps:
s31, the base station receives data to be transmitted from the RB.
S32, the base station analyzes the data to be transmitted to obtain QFI and data load.
In this step, the base station parses the SDAP PDU to obtain QFI and data payload.
And S33, the base station sends data to be transmitted to the core network equipment.
In implementation, the base station loads the data load PDU Session/Tunnel onto the QoS flow marked by QFI, sends the data to be transmitted to the core network equipment, and carries the QFI in the transmission load of the data transmission interface and/or carries the QFI in the data packet transmitted in the QoS flow. If the base station determines that the QoS flow identified by the QFI is a new QoS flow according to the QFI obtained in step S32, searching a corresponding QoS parameter from a correspondence between a pre-configured QFI and QoS parameters, selecting a Tunnel service meeting QoS requirements for the new QoS flow, and if it determines that the QoS flow identified by the QFI is an existing QoS flow, directly transmitting data to be transmitted to the core network device according to the existing QoS service.
It should be noted that the data transmission flow shown in fig. 1 may be implemented by the base station.
