Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for triggering reflection mapping and a network device.
Background
A concept of reflective mapping is introduced in an SDAP (Service Data Adaptation Protocol) Protocol layer of 3GPP to implement fast mapping from QoS Flow (quality of Service Flow) to DRB (Data Radio Bearer).
The core idea of reflection mapping (Reflective mapping) is: and the lower layer (lower layer) bearer channel is selected to be sent when the network side downlink data is sent. When receiving the downlink data packet, the peer terminal side directly sends uplink data on the same bearer channel.
To achieve this flexible control, a reflectogram indication, currently named RQI (Reflective QoS Indicator), is introduced in the header of an SDAP PDU (Protocol Data Unit).
Thus, the system has two ways to control the direct mapping of QoS Flow (quality of service Flow) and DRB: RRC (Radio Resource Control) signaling and RQI signaling carried with the SDAP PDU. The control relationship between the two needs to be well and clearly defined, otherwise system disorder will be caused.
A Reflective mapping mode is introduced for the current 5G SDAP protocol, so that two modes of RRC signaling control and RQI (Reflective QoS Indicator) exist at the same time to implement mapping between QoS Flow and DRB, and how to cooperate the two control modes is not specified in the current protocol, which causes the two control modes to easily cause conflicts.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a method for triggering reflection mapping, which is applied to a network device, and the method includes:
The embodiment of the invention solves the problem of conflict caused by the triggering mode of the RRC sublayer and the triggering mode of the SDAP sublayer in the reflection mapping process through the interaction of the RRC sublayer and the SDAP sublayer.
In an embodiment of the present invention, step 11 may include:
step 111, the RRC sublayer of the network device sends a reflection mapping request to the SDAP sublayer of the network device;
step 112, the RRC sublayer of the network device receives a reflection mapping response message fed back by the SDAP sublayer of the network device, where the reflection mapping response message is information for triggering a reflection mapping process.
Wherein the reflection mapping request comprises: at least one item of information of a terminal, qoS flow information of service quality, and DRB information of new data radio bearer bearing the QoS flow.
The reflection mapping response message includes: at least one of information of a terminal, qoS flow information of service quality, DRB information of new data radio bearer bearing the QoS flow, and identification information triggering the reflection mapping process.
The reflection mapping completion message includes: at least one of information of a terminal, qoS flow information of service quality, DRB information of new data radio bearer of the QoS flow, and identification information for triggering the reflection mapping process.
Further, after the RRC sublayer of the network device receives the reflection mapping completion message sent by the SDAP sublayer of the network device in the method, the method may further include:
step 13, the RRC sublayer of the network equipment sends RRC connection reconfiguration information to the RRC sublayer of the terminal;
step 14, the RRC sublayer of the network device receives the RRC connection reconfiguration complete message fed back by the RRC sublayer of the terminal.
As shown in fig. 2, the specific implementation flow of the method includes:
reflective mapping Request: and the RRC sublayer sends a reflection mapping Request (reflecting mapping Request) to the SDAP sublayer according to the judgment of the RRC sublayer and the requirement of quickly mapping the QoS Flow to a new DRB. After the reflection mapping request is sent, the RRC sublayer does not perform any RRC Reconfiguration operation and deletion operation for the user until receiving the reflection mapping completion notification sent by the SDAP sublayer. In this signaling, the information of the carrier user, the QoS Flow information, and the information of the new DRB carrying the QoS Flow are carried.
After receiving the reflection mapping request, the SDAP starts a reflection mapping processing flow, which at least comprises the following steps: and storing the information and the rule (rule) in the request signaling, setting the RQI to be 1, establishing the SDAP PDU, configuring the QoS Flow and the DRB mapping rule (rule) in the request signaling, and sending the SDAP PDU. Simultaneously, the method also comprises the following steps: restarting SDAP sub-layer to judge relevant parameters or algorithm flow of reflection mapping, and ensuring that a new reflection mapping flow triggered by the SDAP sub-layer is not initiated before the reflection mapping requested by RRC is completed.
Reflective mapping Response: and after the SDAP sublayer receives the reflection mapping request and completes the operation, replying a reflection mapping response to the RRC sublayer. And after receiving the reflective mapping response, the RRC sublayer confirms that the SDAP sublayer starts the reflective mapping process, restarts all monitoring parameters and ensures that a new signaling flow is not initiated any more to reconfigure or delete the user, including reconfiguration of the reflective mapping. In this signaling, the information of the user and the QoS Flow information are carried, the information of the new DRB carrying the QoS Flow, and the identifier of the reflection mapping has been successfully started.
The SDAP sublayer sends DL SDAP PDU to the SDAP sublayer of the UE (terminal), wherein in the DL SDAP PDU, RQI =1, after the SDAP sublayer of the UE receives the reflection mapping indication RQI, the SDAP PDU is received on a new DRB;
UL SDAP PDU on new DRB: these two signallings belong to the SDAP PDU interaction process. The network side sends SDAP PDU on the new DRB according to the configured reflection mapping rule, ensures that the RQI value is 1, is successfully received by the terminal side, and obtains final confirmation by receiving the uplink SDAP PDU on the new DRB.
Reflective mapping Complete message: the SDAP sublayer at the network side receives the SDAP PDU of the expected QoS Flow on the upstream target DRB, which means that the reflection mapping process is successfully completed. The SDAP sublayer sends a reflection mapping completion indication to the RRC sublayer.
After receiving the reflection mapping completion message, the RRC sublayer starts good preparation after reflection mapping, and prepares to update the configuration information and the context information of the user. In this signaling, the information of the carrier user, the QoS Flow information, the information of the new DRB carrying the QoS Flow, and the identifier of the reflection mapping have been completed.
The RRC sublayer sends an RRC Connection Reconfiguration (RRC Connection Reconfiguration message) to the RRC sublayer of the UE;
RRC Connection Reconfiguration Complete (RRC Connection Reconfiguration Complete message): after confirming that the SDAP sublayer completes the reflection mapping, the RRC sublayer performs good post-processing on user information: and updating the mapping information of the QoS Flow and the DRB, wherein the key point is to delete the mapping relation between the QoS Flow and the source DRB, and the information of the users on the network side and the user side is consistent, complete and accurate. This graceful procedure is accomplished by an existing RRC connection reconfiguration.
In this embodiment, in the reflective mapping triggered by the RRC sublayer, at the network side, the RRC and the SDAP introduce an interactive signaling flow: a Reflective mapping Request (Reflective mapping Request), a Reflective mapping Response (Reflective mapping Response), and a Reflective mapping Complete (Reflective mapping Complete).
Wherein, RRC _ Network and SDAP _ Network respectively represent RRC and SDAP protocol sub-layers of a Network side, and RRC _ UE and SDAP _ UE respectively represent RRC and SDAP protocol sub-layers of a terminal side.
For the reflection mapping triggered by the RRC sublayer, the method is adopted by shortening the processing time delay of the signaling by the RRC signaling to realize the rapid mapping from the QoS Flow to the DRB. The RRC sublayer implements fast control by triggering RQI reflection mapping of the SDAP sublayer. And then sending RRC signaling to perform subsequent RRC connection reconfiguration.
In the above embodiment of the present invention, the updating of the mapping information of QoS Flow and source DRB is put to the end through steps 6 and 7, the fast mapping of the reflection mapping is not affected, and the updating of the user information is realized through the reconfiguration process of RRC connection, which not only ensures real-time performance, but also ensures the consistency, completeness and accuracy of the information of the network side and the user side.
In another embodiment of the present invention, the step 11 may include:
step 121, the RRC sublayer of the network device receives a reflection mapping procedure trigger message sent by the SDAP sublayer of the network device.
Wherein the reflection mapping procedure trigger message includes: at least one of information of a terminal, qoS flow information of service quality, DRB information of new data radio bearer bearing the QoS flow, and identification information triggering the reflection mapping process.
The reflection mapping completion message includes: at least one of information of a terminal, qoS flow information of service quality, DRB information of new data radio bearer bearing the QoS flow, and identification information triggering the reflection mapping process.
Further, in the above method, after the RRC sublayer of the network device receives the reflection mapping completion message sent by the SDAP sublayer of the network device, the method may further include:
step 13, the RRC sublayer of the network equipment sends RRC connection reconfiguration information to the RRC sublayer of the terminal;
step 14, the RRC sublayer of the network device receives the RRC connection reconfiguration complete message fed back by the RRC sublayer of the terminal.
As shown in fig. 3, RRC _ Network and SDAP _ Network respectively represent an RRC sublayer and an SDAP sublayer on the Network side, and RRC _ UE and SDAP _ UE respectively represent an RRC sublayer and an SDAP sublayer on the terminal side. The SDAP sublayer triggered reflection mapping process comprises the following steps:
reflective mapping Start (reflective mapping procedure trigger message): the SDAP sublayer determines that a reflection mapping process aiming at QoS Flow to DRB needs to be started according to a correlation algorithm for judging reflection mapping, and the SDAP sublayer sends a reflection mapping starting message (namely the reflection mapping triggering message) to the RRC sublayer.
After receiving the start message of the reflection mapping, the RRC sublayer restarts all the monitoring parameters and ensures that a new signaling flow is not initiated any more to reconfigure or delete the user, including reconfiguration of the reflection mapping. In this signaling, the information of the user and the QoS Flow information are carried, the information of the target DRB carrying the QoS Flow, and the identifier of the reflection mapping has been successfully started.
The SDAP sublayer sends DL SDAP PDU with RQI =1 to the SDAP sublayer of the UE;
UL SDAP PDU on new DRB: these two signallings belong to the SDAP PDU interaction process. And the SDAP sublayer at the network side sends the SDAP PDU on the new DRB according to an expected reflection mapping rule, ensures that the RQI with the value of 1 is successfully received by the SDAP sublayer at the terminal side, and obtains final confirmation by receiving the uplink SDAP PDU on the new DRB.
Reflective mapping Complete: the SDAP sublayer at the network side receives the SDAP PDU of the expected QoS Flow on the uplink target DRB, which means that the reflection mapping process is successfully completed. The SDAP sublayer sends a reflection mapping completion indication to the RRC sublayer.
And after receiving the reflection mapping completion message, the RRC sublayer prepares to update the configuration information and the context information of the user. In this signaling, the information of the bearer user, the QoS Flow information, and the information of the new DRB carrying the QoS Flow already complete the identifier of the reflection mapping.
5. The RRC sublayer of the network side sends to the RRC sublayer of the UE: RRC Connection Reconfiguration;
rrc Connection Reconfiguration Complete: after confirming that the SDAP sublayer completes the reflection mapping, the RRC sublayer updates the user information: and updating the mapping information of the QoS Flow and the DRB, wherein the key point is to delete the mapping relation between the QoS Flow and the source DRB, and the information of the users on the network side and the user side is consistent, complete and accurate.
In this embodiment, the SDAP sublayer decides the triggered reflection mapping by itself, introduces an interactive signaling flow in the RRC sublayer and the SDAP sublayer on the network side, and starts (reflecting mapping Start) and completes (reflecting mapping Complete) the reflection mapping. For the reflection mapping triggered by the self-decision of the SDAP sublayer, in order to ensure the consistency of the configuration parameters of the network side and the terminal side, the SDAP sublayer needs to trigger the RRC sublayer to update the parameters.
In the above embodiment of the present invention, the updating of the mapping information of QoS Flow and source DRB is put to the end through steps 5 and 6, the fast mapping of the reflection mapping is not affected, and the updating of the user information is realized through the reconfiguration process of RRC connection, which not only ensures real-time performance, but also ensures the consistency, completeness and accuracy of the information of the network side and the user side.
The embodiment of the invention ensures the real-time performance of the reflection mapping and also ensures the consistency, completeness and accuracy of the information of the network side and the user side through the interaction of the RRC sublayer and the SDAP sublayer; and the terminal side is not required to be modified, and the implementation is simple.
