Background technique

In the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) protocol, it is stipulated that each time a QoS flow (Quality of Service flow) is established, the QoS parameters to be synchronized are configured.

After introducing reflective mapping (reflective mapping) at the AS layer (Access Stratum) on the base station side and the terminal side, each time the QoS flow reaches the target RB (Radio Bearer) through the reflection mapping operation, the target RB needs to be This QoS flow provides suitable QoS guarantee.

The above method of configuring the corresponding QoS parameters each time a QoS flow is established is faced with a paradox after introducing the reflection mapping scheme at the network side radio access network and the terminal side AS layer:

For the target RB, it is necessary to provide QoS guarantee for the newly added QoS flow, but the QoS parameters of the QoS flow need to be configured through signaling. Similarly, the QoS parameters of the target RB need to be modified because of the newly added QoS flow that needs to be carried; The QoS parameters also need to be modified because the QoS flow is reduced. Modifications in both cases need to be configured through signaling.

Then, since signaling configuration is required, the mapping relationship between the QoS flow and the RB (including the source RB and target RB) can be directly carried in the signaling, and configured to the relevant functional parts of the base station and the terminal; however, so Configuration, reflection mapping has no effect.

detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the drawings and specific embodiments.

As shown in FIG. 1, some embodiments of the present disclosure provide a flow mapping method, which is applied to a transmission node, and includes:

Step 11: Obtain the first QoS parameter of the first data stream using the quality of service QoS flow identifier of the first data stream as an index; the first QoS parameter includes a radio bearer RB information clause, and the RB information clause is used to identify an RB.

In this step, the RB information clause identifies all RBs capable of carrying the first data stream; the RB information clause can record information of multiple RBs, and the information of each RB includes at least the ID of the RB.

Step 12: According to the RB information clause, map the first data stream to a target RB capable of carrying the first data stream and send it.

It should be noted that a data flow can also be called a QoS flow, that is, a QoS flow; a QoS flow ID (QoS flow ID, which can be referred to as QFI) is an identification of a data flow, and the value of each QFI uniquely identifies a data flow. Each data stream has corresponding QoS parameters, also known as QoS profiles.

The transmission node mentioned in some embodiments of the present disclosure may be a terminal device or a network side device. In some embodiments of the present disclosure, the terminal device and the network-side device are configured with the same QFI as the indexed QoS parameter. When the terminal device and the network-side device receive a data flow, the QoS flow identifier of the data flow can be quickly obtained. For the QoS parameters of the data stream, each RB can improve its own QoS parameters according to the QoS parameters of each QoS stream carried.

Optionally, in the foregoing embodiment of the present disclosure, the RB information clause includes: identification information of N RBs (for example, RB ID), and N is an integer greater than or equal to zero.

Some embodiments of the present disclosure first need to determine whether the first data stream has an available RB according to the RB information clause of the first QoS parameter.

As an optional embodiment, step 12 includes:

Map the first data stream to the target RB and send it.

Wherein, the method further includes:

or,

Optionally, the selecting one RB from the at least one available RB as the target RB capable of carrying the first data stream includes:

According to the QoS support capability of the available RBs, one RB is selected from at least one available RB as the target RB; for example, the value of each QoS parameter is selected to be greater than the QoS requirement of the first data stream, and the number of data streams carried is relatively small RB.

or,

According to the type of data stream carried by the available RBs, one RB is selected from at least one available RB as the target RB; for example, a small data packet with a length of no more than 100 bytes is carried on one RB, and the data packet of the first data stream If the data packet is a small data packet with a length of no more than 100 bytes, the RB is selected as the target RB.

As another optional embodiment, the mapping the first data stream to a target RB capable of carrying the first data stream and sending according to the RB information clause includes:

Map the first data stream to the target RB and send it.

If there are no available RBs in the RB information clause of the first QoS parameter of the first data flow, a suitable target RB needs to be selected according to the QoS flow identifier of the first data flow. In this case, the data flow identified by the QoS flow identifier of the first data flow is a new data flow for the target RB. This new data stream can be directly mapped through reflection mapping, or directly configured through signaling, but this change may not be indicated to the target RB in advance, and the target RB only needs to receive the The data packet identified by the QoS flow identification can be determined by itself.

Optionally, the method further includes:

or,

If any of the foregoing conditions is met, a new RB needs to be selected for the first data stream, and it can be determined that there is no available RB for the first data stream.

Specifically, the selecting the target RB capable of carrying the first data flow according to the QoS flow identifier of the first data flow includes:

If there is a second QoS parameter in the QoS parameter set where the first QoS parameter of the data flow indicated by the QoS flow identifier of the first data flow is located, the RB information clause of the second QoS parameter identifies a second QoS parameter that can carry the first QoS parameter. A data flow RB, and the second QoS parameter can support the QoS requirements of the first data flow, the RB identified by the RB information clause of the second QoS parameter is determined as the target RB; otherwise, a new RB is selected RB as the target RB. Optionally, the new RB specifically refers to: an RB that has not carried any data stream.

Specifically, the available RB is searched for according to the QoS parameter of the first data flow indicated by the QoS flow identifier. If there is an RB information clause of a QoS parameter in the entire QoS parameter set, and there is an RB in the RB information clause, which can carry the first data flow, and its QoS parameters can support the QoS requirements of the first data flow, then Use this RB as the target RB; if there is no available RB in the entire QoS parameter set, a brand new RB is selected to carry the first data flow.

Further, after selecting the target RB capable of carrying the first data flow according to the QoS flow identifier of the first data flow, the method further includes:

Determine whether other data streams are already carried on the target RB;

In other words, if the target RB carries other data streams, it is further judged whether the QoS guarantee capability of the RB (whether the RB's QoS parameter value can meet the QoS parameter requirements of the first data stream) can meet the QoS of the first data stream Claim.

If it cannot be guaranteed, that is, the QoS requirements of the data streams already carried on the RB are lower than the requirements of the first data stream, the QoS parameters of the RB are updated according to the QoS parameters of the first data stream; the RB records the QFI as the The RB has already carried the query basis for the data packet identified by the QFI.

If no other data stream is carried on the RB, the QoS parameter of the data stream is directly assigned to the QoS parameter of the RB. The RB records the QFI as a query basis for the data packet identified by the QFI that the RB has carried.

According to the QFI of the data flow, query the QoS parameters of the data flow stored locally, and index the QoS parameters of the QoS flow in the RB information clause of the QoS parameters.

Further, the method further includes:

In order to more clearly describe the flow mapping method provided by some embodiments of the present disclosure, the detailed steps of the flow mapping method are described below, as shown in Fig. 2:

When the functional entity of the RB receives a data stream or reflection mapping or other triggers a data stream to be mapped to an RB,

1. First, read the RB information clause of the QoS parameter through the QoS flow identifier (QFI) of the data flow;

2. Determine whether there is an available RB according to the RB information clause.

3. If there are one or more available RBs, select a suitable RB from all available RBs;

4. Carry the data stream to the selected RB and send it out;

5. If there is no available RB, select an appropriate RB according to the QFI of the data stream.

6. Determine whether there are other data streams on the selected RB;

7. If there are other data flows, judge whether the QoS guarantee capability of the RB can already support the QoS requirements of the data flow;

8. If it cannot be supported, update the QoS parameters of the RB so that the RB can guarantee the QoS requirements of all data streams carried;

9. There is no other data flow on the RB, and the QoS parameter of the data flow is assigned to the RB as the RB's QoS parameter;

10. Record the RB information in the RB information clause of the QoS parameter.

In summary, in the above-mentioned embodiments of the present disclosure, when a transmission node receives a data flow, it uses the QoS flow identifier of the data flow as an index to obtain QoS parameters, and maps the data flow to the data flow according to the RB information clause included in the QoS parameters. The data stream is sent on the target RB that carries the data stream, thereby realizing fast mapping of the data stream to the RB.

As shown in Figure 3, some embodiments of the present disclosure also provide a method for setting the quality of service QoS parameters of a radio bearer RB, including:

Step 31: Set the QoS parameter of the RB according to the data flow carried by the RB.

In some embodiments of the present disclosure, when the network side device establishes the user's RB, it establishes one RB or multiple RBs at a time, but each RB does not preset QoS parameters, and the QoS parameters of each RB are based on the data flow carried by it. QoS parameter generation.

The network side device configures the terminal to establish an RB through the existing radio resource control RRC signaling, and the established RB does not include QoS parameters. When the network-side device establishes an RB, each RB does not contain QoS parameters and bearer QFI. The network-side device sends the RB configuration information to the terminal, and the terminal locally saves the RB configuration information.

Optionally, the setting of the QoS parameter of the RB according to the data flow carried by the RB includes:

That is, if the RB is a blank RB and has not carried any data flow, the QoS parameter of the first data flow carried is directly assigned to the RB as its QoS parameter.

That is, if the RB already has QoS parameters, when a data stream needs the RB to carry, if the data stream has sent data on the RB, the QoS parameters of the RB are not updated, and the data stream is directly sent on it. If the data flow sends data on the RB for the first time, if the QoS requirement of the data flow is within the QoS support capability of the RB, the QoS parameters of the RB are not updated; if the QoS requirement of the data flow exceeds The QoS support capability of the RB will update the QoS parameters of the RB.

Further, when the QoS requirement of the third data flow exceeds the QoS support capability of the RB, updating the QoS parameter of the RB includes:

or,

Specifically, a mathematical method is used to perform weighted fitting, and different weights are set for different QoS levels. This requires that when selecting RBs through QFI, the QoS requirements of the data stream carried on an RB should be selected as much as possible. Distributed around the average value to ensure that the QoS parameters of the RB cannot be too discrete.

As shown in Figure 4, set a reasonable QoS capability range for each RB, such as QoSmin-QoSmax until now, and then perform self-learning and self-adjustment according to the QoS requirements of each QoS flow carried and the amount of data it needs to send.

The initial QoS parameter value of an RB comes from the QoS parameter value of the data flow (also called QoS flow) carried by the first bearer. In the subsequent operation process, dynamic fitting is performed according to the set weight.

It should be noted that the flow mapping method and the QoS parameter setting method provided by some embodiments of the present disclosure are applicable to both terminal-side devices and network-side devices.

For example, when the network side device serves as the sender, the network side device selects an appropriate RB according to the above-mentioned flow mapping method, and updates the QoS parameters of the RB. When the network side device serves as the receiving end, the network side is responsible for scheduling the radio resources (UL Grant: Uplink Grant) required for each terminal to send data. In some embodiments of the present disclosure, when the network side device schedules uplink radio resources, The specific LCG (Logical Channel Group, logical channel group) is no longer scheduled, and the uplink radio resource grant (UL Grant) is only performed according to the amount of data that can be sent. After the network side device receives the uplink data, it does not perform special processing on the QoS parameters of the RB.

For another example, when the terminal device serves as the sender, the terminal device selects an appropriate RB according to the above-mentioned flow mapping method, and updates the QoS parameters of the RB. Then, according to the uplink radio resource authorization of the network-side device, each LCG (the relationship between the LCG and the RB still follows the content of the agreement) is allocated the amount of data that can be sent. The QoS parameters of the RB are calculated and updated according to the data flow carried by the RB, and the QoS parameters of the LCG carrying the RB are also calculated through the RB carried by the RB, and the QoS parameters are self-learning and updated. When the terminal device serves as the receiving end, it receives and processes the data sent by the network side device.

It should be further noted that when the reflection mapping is initiated for a QoS flow, an available RB is selected for the QoS flow according to the flow of FIG. 2. After the available RB selection is determined:

The QoS flow directly sends data packets on the target RB. The target RB can update the QoS parameters.

After the QoS flow leaves the source RB, the source RB does not need to perceive this change, and according to the existing processing method, sends the data that has been reached, and receives the data that needs to be received. At the same time, because after the QoS flow leaves the source RB, the data of the QoS flow carried on the source RB will inevitably decrease or even no longer be sent. Then, according to the self-learning method of the RB, the RB will reduce the influence of the QoS parameters of the QoS flow. Therefore, the QoS flow can be deleted from the RB, or it can be kept unchanged.

In summary, in the above-mentioned embodiments of the present disclosure, when the network side device establishes the user's RB, it establishes one RB or multiple RBs at a time, but each RB does not preset QoS parameters, and the QoS parameters of each RB are based on the The QoS parameter generation of the data stream; the sender self-learns and dynamically adjusts the QoS parameters to ensure the QoS requirements when the data packet is sent.
