Description

Method for identifying service quality and wireless access network element equipment
Technical Field
The present invention relates to wireless communication technologies, and in particular, to a method for identifying quality of service (QoS) and a wireless access network element device.
Background
In a 5G scenario, a flow-based QoS scheme is to be implemented to replace a QoS mechanism of an end-to-end evolved packet system bearer (EPS bearer) so as to implement QoS control with finer granularity and better meet a service requirement of a user. One key point to achieve this is to identify traffic flows (flows).
Currently, the process of identifying flow in the prior art is: the flow QoS of the Uplink (UL) adopts the same identification as the flow QoS of the Downlink (DL), namely, the uplink adopts the same QoS identification as the downlink, and for the downlink, the identification of the DL service flow is completed in a core network and then is transmitted to a wireless network for processing.
The problems existing in the prior art are as follows: 1) on the first hand, from the perspective of reflexive QoS, it is necessary for the DL air interface user plane to display and transmit a QoS Flow ID identifier, that is, to display QoS Flow M- > DRB N mapping, so as to implement mapping of QoS Flow M to DRB N of the terminal UL, which may cause waste of air interface resources. The mapping from the QoS Flow M to the DRB N is a specific implementation of mapping from a service quality Flow to an air interface data bearer. In the second aspect, from the UL perspective, since the Radio Access Network (RAN) does not sense the information of the IP Flow T, the air interface user plane needs to transmit a QoS Flow ID M identifier, and the identifier of the QoS Flow M of the UL is implemented in the RAN to achieve the purpose of transmitting the identifier (transport marking), which also causes waste of air interface resources.

Step 203, after the wireless access network element device perceives the IP data stream, the identified QoS stream is obtained on the wireless access network element device side according to the mapping relationship, and the transmission identifier is transmitted for the uplink data transmission.
With the embodiment of the present invention, through the above step 201 and 203, the dedicated signaling (for example, RRC reconfiguration signaling) sent by the radio access network element device to the UE carries the mapping relationship, where the mapping relationship is used to represent the mapping between the IP data stream, the QoS stream, and the DRB, so that the UE can select the IP data stream, the QoS stream, and the DRB according to the mapping relationship. Subsequently, after mapping the QoS flow to the DRB and performing data transmission, if the mapping from the QoS flow reflecting the QoS to the DRB is changed, the radio access network element device notifies the UE of the change in the mapping relationship through the dedicated signaling (e.g., RRC reconfiguration signaling).

After the mapping 'QoS flow M to DRB N mapping' is added, the mapping relation of 'uplink IP flow- > QoS flow- > DRB' is obtained, and the UE can realize the selection of T- > M- > N through the mapping relation of 'uplink IP flow- > QoS flow- > DRB'. The mapping of UL QoS flow to DRB is realized by using a special signaling, namely RRC reconfiguration signaling, so that the waste caused by the transmission of QoS flow ID by an air interface is avoided. 1) First, the mapping of the reflective QoS UL DRB is realized on the RAN side corresponding to the "reflective QoS from the perspective of reflective QoS"; 2) secondly, the function of sensing IP flow is introduced on the RAN side, corresponding to "from the UL perspective", and is realized by UL transport marking.
