The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
In the embodiment of the invention, the QoS parameters which can be indexed through the QFI are pre-configured on the data transmission interface, so that the configured QoS parameters can be different for different services in specific implementation. In this way, the data to be transmitted needs to carry the corresponding QFI, so that the data receiving end searches the corresponding QoS parameter according to the QFI and provides the service meeting the QoS requirement according to the searched QoS parameter.
As shown in fig. 1, which is a schematic diagram of an implementation flow of a data transmission method provided in an embodiment of the present invention, the method includes the following steps:
and S11, when the data to be transmitted is received, obtaining the QFI corresponding to the data to be transmitted.
S12, searching the QoS parameter corresponding to the QFI obtained from the corresponding relation between the QFI and the QoS parameter configured in advance.
And S13, transmitting the data to be transmitted according to the searched QoS parameters.
The following describes a specific implementation process of the embodiment of the present invention with reference to transmission flows 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 base stations, and the Xn interfaces are data transmission interfaces between the base stations. In specific implementation, the corresponding relationship between the QFI and the QoS parameter may be pre-configured at NgAP or XnAP, so that, during data transmission, the corresponding QoS parameter may be searched according to the configured corresponding relationship and the QFI, and accordingly, a corresponding QoS guarantee is provided for the service. For convenience of description, data transmission of Ng interfaces is taken as an example in the following description, and a data transmission flow between Xn interfaces is similar to a data transmission flow between Ng interfaces.
Firstly, 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-established QoS flow exists, the Ng interface does not need to carry the QoS parameter configuration signaling corresponding to the QFI, and the data can be directly transmitted on the selected QoS flow.
For downlink data transmitted by the core network device to the base station, the core network first determines whether the identified QoS flow is a newly-created QoS flow according to the QFI, specifically, whether the QFI exists in the recorded QFI in the QoS flow already carrying the data packet, and if the QFI does not exist, the core network determines that the QoS flow is a newly-created QoS flow. According to QFI, the core network device loads the data packet in the IP flow onto the corresponding QoS flow, and carries the QFI in the Ng interface transmission load (e.g., 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 QFI from the data transmission interface, i.e. from the transmission bearer of the Ng interface in this example, and/or obtains QFI from the data packet of the QoS stream for transmitting the data to be transmitted. If the QOS flow corresponding to the QSI is judged to be the newly-built QoS flow by the base station according to the obtained QSI, the base station records the obtained QSI, searches the corresponding QoS parameter according to the QSI, and establishes a new RB (radio bearer) for transmitting data to be transmitted according to the searched QoS parameter; or selecting the RB meeting the corresponding QoS requirement from the existing RBs to transmit the 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 already bearing the data packet, the core network device bears 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 a data packet transmitted in a QoS flow, and sends data to be transmitted to the base station.
After receiving the data to be transmitted from the QoS stream, the base station obtains QFI from the transmission bearer of the Ng interface and/or obtains QFI from the data packet of the QoS stream for transmitting the data to be transmitted from the data transmission interface, in this example, obtains QFI from the transmission bearer of the Ng interface, determines that the QoS stream corresponding to the QFI is the existing QoS stream according to the QFI, and transmits the data to be transmitted by using the RB used for transmitting the data in the QoS stream last time.
As shown in fig. 2, it is a schematic diagram of a data transmission flow between a core network device (CN) and a base station (gNB), and includes the following steps:
s21, CN receives data to be transmitted.
S22, CN transmits data to be transmitted to base station.
Specifically, the CN transmits data to be transmitted to the base station through PDU Session/Tunnel.
And S23, the base station transmits the data to be transmitted.
In specific implementation, the data transmitted by the transmission bearer or the QoS stream in the base station includes the acquired QFI, if the new QoS stream is determined according to the QFI, the QoS parameter corresponding to the new QoS stream is searched in the correspondence between the QFI and the QoS parameter configured in advance according to the QFI, and then the new radio bearer RB to transmit the data to be transmitted meeting the QoS requirement is established according to the searched QoS parameter, or the RB to transmit the data to be transmitted meeting the QoS requirement is selected from the existing RBs. And if the current QoS flow is judged according to the QFI, transmitting the data to be transmitted by using the RB used for transmitting the data in the QoS flow last time.
And secondly, 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 data load, loads the data load on QoS flow of QFI identification, sends the data to be transmitted to core network equipment, and carries the QFI in 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 device records the QFI and sends a data packet received from the QoS flow to an upper layer for processing if determining that a new QoS flow is created according to the QFI, and directly sends the data packet received from the QoS flow to the upper layer for processing if determining that an existing QoS flow is created according to the QFI.
As shown in fig. 3, it is a schematic flow chart of a base station transmitting data to a core network device, and includes the following steps:
s31, the base station receives the data to be transmitted from the RB.
And 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 the QFI and the data load.
And S33, the base station sends the data to be transmitted to the core network equipment.
In specific implementation, the base station loads a data load PDU Session/Tunnel to a QoS flow identified by QFI, sends data to be transmitted to core network equipment, and carries the QFI in a transmission load of a data transmission interface and/or carries the QFI in a data packet transmitted in the QoS flow. If the base station determines that the QoS flow identified by the QFI is a newly-established QoS flow according to the QFI obtained in step S32, searching a corresponding QoS parameter from a pre-configured correspondence between the QFI and the QoS parameter, selecting a Tunnel service meeting the QoS requirement for the newly-established QoS flow, and if the QoS flow identified by the QFI is determined to be 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 procedure shown in fig. 1 may be implemented by the base station.
