Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a stream mapping method, a setting method of QoS parameters of RBs, and a transmission node.
Background
In the 3GPP protocol, configuration QoS parameters to be synchronized are specified each time QoS flow (Quality of Service flow) is established.
After introducing reflective mapping (reflective mapping) in the AS layers (Access Stratum, Access layer) at the base station side and the terminal side, after a QoS stream passes through a reflective mapping operation to a target RB (Radio Bearer) each time, the target RB needs to provide a suitable QoS guarantee for the QoS stream.
After the above-mentioned way of configuring QoS parameters corresponding to each QoS flow established, a reflection mapping scheme is introduced into the network side radio access network and the terminal side AS layer, a paradox is faced:
for the target RB, QoS guarantee needs to be provided for the newly added QoS flow, but the QoS parameters of the QoS flow need to be configured through signaling, and similarly, the QoS parameters of the target RB need to be modified because the QoS flow needing to be carried is newly added; the QoS parameters of the source RB also need to be modified because of the reduced QoS flow. The modification in both cases needs to be configured by signaling.
Then, since the signaling configuration is needed, the mapping relationship between the QoS flow and the RB (including the source RB and the target RB) can be directly carried in the signaling and configured to the relevant functional parts of the base station and the terminal; so configured, however, the reflection map is not functional.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a stream mapping method, where the mapping method is applied to a transmission node, and the method includes:
In this step, the RB information clause identifies all RBs that can carry the first data stream; the RB information term may record information of a plurality of RBs, the information of each RB including at least an ID of the RB.
And step 12, mapping the first data stream to a target RB capable of carrying the first data stream according to the RB information clause, and sending the first data stream.
It should be noted that, the data flow may also be referred to as QoS flow, i.e. QoS flow; a QoS flow ID (QFI for short) is an identifier of a data flow, and a value of each QFI uniquely identifies one data flow. Each data flow has corresponding QoS parameters, also called QoS profiles.
The transmission node mentioned in the embodiment of the present invention may be a terminal device, or may be a network side device. The embodiment of the invention configures the same QFI as the indexed QoS parameter for the terminal equipment and the network side equipment, when the terminal equipment and the network side equipment receive a data stream, the QoS parameter of the data stream can be quickly obtained according to the QoS stream identification of the data stream, and each RB can perfect the QoS parameter of the RB according to the QoS parameter of each loaded QoS stream.
Optionally, in the foregoing embodiment of the present invention, the RB information term includes: identification information of N RBs (for example, IDs of RBs), N being an integer greater than or equal to 0.
In the embodiment of the present invention, it is first required to determine whether there is an available RB in the first data stream according to the RB information term of the first QoS parameter.
As an alternative embodiment, step 12 comprises:
determining that there is at least one available RB according to the RB information term;
selecting one RB from the at least one available RB as a target RB capable of carrying the first data stream;
and mapping the first data stream to the target RB and transmitting the first data stream.
Wherein the method further comprises:
if the RB information clause identifies at least one RB, determining that an available RB exists;
alternatively, the first and second electrodes may be,
and if the RB information clause identifies at least one RB, determining that an available RB set cannot be expanded for the first data stream according to a preset rule, and determining that the available RB exists.
Optionally, the selecting one RB from the at least one available RB as a target RB capable of carrying the first data stream includes:
selecting one RB from the at least one available RB as a target RB according to QoS support capability of the available RB; for example, the RB which has a value of each QoS parameter greater than the QoS requirement of the first data flow and carries a smaller number of data flows is selected.
Alternatively, the first and second electrodes may be,
selecting an RB from at least one available RB as a target RB in a random mode;
alternatively, the first and second electrodes may be,
selecting one RB from at least one available RB as a target RB according to the type of the data stream carried by the available RB; for example, a RB carries small packets with a length of no more than 100 bytes, and the packet of the first data stream is a small packet with a length of no more than 100 bytes, the RB is selected as the target RB.
As another optional embodiment, the mapping and sending the first data stream to a target RB capable of carrying the first data stream according to the RB information term includes:
determining that there is no available RB according to the RB information clause;
selecting a target RB capable of bearing the first data flow according to the QoS flow identification of the first data flow;
and mapping the first data stream to the target RB and transmitting the first data stream.
If there are no available RBs in the RB information clause of the first QoS parameter for the first data flow, then a suitable target RB needs to be selected based on the QoS flow identification for 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. The new data stream may be directly mapped out by a reflective mapping manner or directly configured by signaling, but the change may not be indicated to the target RB in advance, and the target RB only needs to decide by itself when receiving the packet identified by the QoS stream identifier.
Optionally, the method further includes:
if the RB is not identified in the RB information clause, determining that no available RB exists;
alternatively, the first and second electrodes may be,
and if the RB information clause identifies at least one RB, determining that an available RB set can be expanded for the first data stream according to a preset rule, and determining that no available RB exists.
If any of the above conditions is met, it may be determined that there is no available RB for the first data stream that a new RB needs to be selected for the first data stream.
Specifically, the selecting a target RB capable of carrying the first data flow according to the QoS flow identifier of the first data flow includes:
if a second QoS parameter exists in a QoS parameter set where a first QoS parameter of a data flow indicated by a QoS flow identifier of the first data flow is located, an RB information clause of the second QoS parameter identifies an RB capable of bearing the first data flow, and the second QoS parameter can support the QoS requirement of the first data flow, and the RB identified by the RB information clause of the second QoS parameter is determined to be the target RB; otherwise, a new RB is selected as the target RB. Preferably, the new RB specifically refers to: RBs that do not carry any data streams.
Specifically, the available RB is searched for according to the QoS parameter of the first data flow indicated by the QoS flow identifier. If an RB information clause of one QoS parameter exists in the entire set of QoS parameters, an RB exists in the RB information clause, which can carry the first data flow and whose QoS parameter can support the QoS requirement of the first data flow, then the RB is used as the target RB; if no RBs are available in the entire set of QoS parameters, a completely 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:
judging whether other data streams are carried on the target RB;
under the condition that other data flows are carried on a target RB, if the QoS guarantee capability of the target RB cannot meet the QoS requirement of a first data flow, updating the QoS parameter of the target RB according to a first QoS parameter of the first data flow;
and under the condition that other data flows are not carried on the target RB, assigning the first QoS parameter of the first data flow as the QoS parameter of the target RB.
In other words, if other data flows are carried on the target RB, it is further determined whether the QoS guarantee capability of the RB (whether the QoS parameter value of the RB can satisfy the QoS parameter requirement of the first data flow) can satisfy the QoS requirement of the first data flow.
If the QoS of the data flow which is carried on the RB is not guaranteed to be lower than the QoS of the first data flow, updating the QoS parameter of the RB according to the QoS parameter of the first data flow; and the RB records the QFI as a query basis for the data packet which has been carried by the RB and is identified by the QFI.
And if no other data flow is carried on the RB, directly assigning the QoS parameter of the data flow as the QoS parameter of the RB. And the RB records the QFI as a query basis for the data packet which has been carried by the RB and is identified by the QFI.
And inquiring the QoS parameter of the data flow stored locally according to the QFI of the data flow, indexing the QoS parameter of the QoS flow, and obtaining the RB information clause of the QoS parameter.
Further, the method further comprises:
recording identification information of the target RB into RB information clauses of a first QoS parameter of the first data stream.
In order to more clearly describe the mapping method of the stream provided by the embodiment of the present invention, the following detailed steps of the mapping method of the stream are described, as shown in fig. 2:
when the functional entity of an RB receives a data stream or reflects the mapping or otherwise triggers a data stream to be mapped to an RB,
1. firstly, reading RB information clauses of QoS parameters through a QoS Flow Identifier (QFI) of a data flow;
2. and judging whether available RB exists according to the RB information clause.
3. Selecting a suitable RB from all available RBs, if one or more available RBs exist;
4. carrying the data stream to the selected RB and sending the data stream;
5. if there are no RBs available, the appropriate RB is selected based on the QFI of the data stream.
6. Judging whether other data streams exist on the selected RB;
7. if other data flows exist, judging whether the QoS guarantee capability of the RB can support the QoS requirement of the data flow;
8. if the data flow can not be supported, updating the QoS parameter of the RB so that the RB can guarantee the QoS requirement of all the carried data flows;
9. the RB does not have other data flows, and the QoS parameter of the data flow is assigned to the RB as the QoS parameter of the RB;
10. the RB information is recorded into RB information clauses of the QoS parameters.
In summary, in the above embodiments of the present invention, when a transmission node receives a data stream, the QoS parameter is obtained by using the QoS stream identifier of the data stream as an index, and the data stream is mapped to the target RB capable of carrying the data stream according to the RB information clause included in the QoS parameter, so as to implement fast mapping from the data stream to the RB.
As shown in fig. 3, an embodiment of the present invention further provides a method for setting a quality of service QoS parameter of a radio bearer RB, including:
and step 31, setting the QoS parameters of the RB according to the data flow carried by the RB.
In the embodiment of the invention, when the network side equipment establishes the RB of the user, one RB or a plurality of RBs are established at one time, but each RB does not preset QoS parameters, and the QoS parameters of each RB are generated according to the QoS parameters of the data flow carried by the RB.
The network side equipment configures the terminal to establish the RB through the existing radio resource control RRC signaling, and the established RB does not contain the QoS parameter. When the network side equipment establishes the RB, each RB does not contain the QoS parameter and the borne QFI, the network side equipment sends the configuration information of the RB to the terminal, and the terminal locally stores the configuration information of the RB.
Optionally, the setting the QoS parameter of the RB according to the data flow carried by the RB includes:
and if the RB does not set the QoS parameter, assigning the QoS parameter of the first data flow carried by the RB to the RB as the QoS parameter of the RB.
That is, if the RB is a blank RB and no data stream has been carried, the QoS parameter of the first data stream carried is directly assigned to the RB as its QoS parameter.
Optionally, the setting the QoS parameter of the RB according to the data flow carried by the RB includes:
if the RB is provided with the QoS parameters and the third data stream is sent on the RB for the first time, when the QoS requirement of the third data stream exceeds the QoS supporting capacity of the RB, updating the QoS parameters of the RB; otherwise, not updating the QoS parameters of the RB.
That is, if the RB already has QoS parameters, when a data flow needs the RB bearer, if the data flow has sent data on the RB, the QoS parameters of the RB are not updated, and the data flow is directly sent on the data flow. If the data flow sends data for the first time on the RB, not updating the QoS parameters of the RB if the QoS requirement of the data flow is within the QoS support capability range of the RB; if the QoS requirement of the data flow exceeds the QoS support capability of the RB, the QoS parameters of the RB are updated.
Further, the updating the QoS parameter of the RB when the QoS requirement of the third data flow exceeds the QoS supporting capability of the RB includes:
assigning the QoS parameter of the third data flow to the RB as the QoS parameter of the RB;
alternatively, the first and second electrodes may be,
and performing weighted fitting on the QoS parameters of the third data stream and the QoS parameters of the RB, and assigning the QoS parameters obtained through weighted fitting to be the RB as the QoS parameters of the RB.
Specifically, a mathematical method is used for performing weighted fitting, and different weights are set for different QoS classes, which requires that when an RB is selected by QFI, QoS requirements of data streams carried on one RB selected as much as possible are distributed around an average value more uniformly, and it is ensured that QoS parameters of the RB cannot be too discrete.
As shown in fig. 4, a reasonable QoS capability-only interval, such as QoSmin-QoSmax, is set for each RB, and then self-learning and self-adjusting is performed according to the QoS requirement of each QoS flow carried and the amount of data that needs to be transmitted.
The initial QoS parameter value for an RB is derived from the QoS parameter value of the data flow (also referred to as QoS flow) associated with the first bearer. And in the following operation process, performing dynamic fitting according to the set weight.
It should be noted that the flow mapping method and the QoS parameter setting method provided in the embodiments of the present invention are applicable to both terminal-side devices and network-side devices.
For example, when the network side device serves as the sending end, the network side device selects an appropriate RB according to the above-mentioned stream mapping method, and updates the QoS parameter of the RB. When the network side device serves as a receiving end, the network side is responsible for scheduling wireless resources (UL Grant: uplink Grant) required when each terminal transmits data to the network side. After receiving the uplink data, the network side device does not perform special processing on the QoS parameters of the RB.
For another example, when the terminal device is used as the transmitting end, the terminal device selects an appropriate RB according to the above-described stream mapping method, and updates the QoS parameter of the RB. And then, according to the uplink radio resource authorization of the network side equipment, allocating the data volume which can be transmitted to each LCG (the relation between the LCG and the RB still follows the content of the current protocol). And calculating and updating the QoS parameters of the RB according to the data stream borne by the RB, calculating the QoS parameters of the LCG bearing the RB through the RB borne by the LCG bearing the RB, and performing self-learning updating. And when the terminal equipment is used as a receiving end, receiving and processing data sent by the network side equipment.
It is further noted that when reflection mapping is initiated for a QoS flow, the available RBs are selected for the QoS flow according to the flow of fig. 2. After the available RB selection is determined:
the QoS flow sends packets directly on the target RB. The target RB may update the QoS parameters.
After the QoS flow leaves the source RB, the source RB does not need to sense the change, and finishes transmitting the reached data according to the existing processing method and finishes receiving the data to be received. Meanwhile, after the QoS flow leaves the source RB, the data of the QoS flow carried on the source RB is inevitably reduced, even is not sent any more, and then according to the self-learning manner of the RB, the RB can reduce the influence weight of the QoS parameter of the QoS flow, so the QoS flow can be deleted from the RB, or can be retained without deletion.
In summary, in the above embodiments of the present invention, when the network side device establishes the RB of the user, one RB or multiple RBs is established at a time, but each RB does not preset the QoS parameter, and the QoS parameter of each RB is generated according to the QoS parameter of the data stream carried by the RB; the sending end self-learns and dynamically adjusts the QoS parameters, and the QoS requirement when the data packet is sent is guaranteed.
