The specific embodiment of the present invention is described in detail.
The flow chart that Fig. 3 shows a kind of bearer quality of service control method in the embodiment of the present invention.Such as
Bearer quality of service control method shown in Fig. 3, can include：
Step S301：The descending biography transmitted via WLAN in obtaining the carrying that mobile terminal is measured and reported
Defeated speed or data packet number information.
It is in being embodied as, when mobile terminal is in LTE and WLAN converges state, default when meeting
Report condition when, in the carrying that mobile terminal can be created to which via WLAN transmit downlink transfer speed
Rate or data packet number are measured accordingly, and corresponding measurement result is sent to servicing the movement
The base station of terminal.Wherein, default report condition can be agreement report condition set in advance, also may be used
Being report condition that base station is arranged by signaling.
Wherein, default report condition can be to reach the default periodic report time, i.e. mobile terminal is pressed
Report according to default report cycle.Wherein, the report cycle that each different non-MCG is carried can be with identical
Or it is different.Default report condition can also trigger reporting for mobile terminal by corresponding event, such as divide
Split carrying (Split Bearer) or shift what carrying (Switched Bearer) was transmitted via WLAN
Downlink transmission rate (i.e. downlink transmission data rate, because not transmitting the mobile terminal via WLAN
RRC signaling and Non-Access Stratum signaling, therefore the downlink transmission rate transmitted via WLAN refers to lower line number
According to transfer rate) less than predetermined the first thresholding (thresholding can be 0), or higher than predetermined second
Thresholding, or, it is also possible to via the downlink grouped data convergence protocol packet (PDCP that WLAN is transmitted
PDU when quantity) is less than default first amount threshold, or during higher than default second amount threshold,
Execution is reported.
In being embodied as, the threshold value and threshold value can be preset using agreement, or by base station
Arranged by signaling.
Mobile terminal can be directed to each Split Bearer and Switched according to default report condition
Bearer is independently reported, or is reported together.Default concrete case is reported to be entered by base station when described
During row configuration, base station can configure the total message transmission rate of the multiple carryings of mobile terminal reporting.
In being embodied as, the downlink transmission rate of all carryings of mobile terminal reporting can be all Jing
The information of the downlink transmission rate sum transmitted by WLAN, or carry for each different non-MCG
Downlink transmission rate information, or each non-MCG is carried in Preset Time and passes via WLAN
The quantity information of defeated packet.
For example, when mobile terminal is in LTE and WLAN and converges state, 4 in mobile terminal, are established
Individual carrying business, respectively DRB1, DRB2, DRB3 and DRB4.Wherein, DRB1 is guarantee ratio
Special speed (Guaranteed Bit Rate, GBR) business, base station are configured to MCG carryings, i.e., by base
Stand and be responsible for the data transfer of the business.DRB2 is Non-GBR business, and base station is configured to Split Bearer,
It is responsible for the downlink data transmission of the business by base station and WLAN, upstream data is still responsible for biography by base station
It is defeated.DRB3 is GBR traffic, and base station is configured to Split Bearer.DRB4 is Non-GBR business,
Base station is configured to Switched Bearer, i.e., be responsible for the downlink data transmission of the business by WLAN, up
Or transmission is responsible for by base station.
Such as, mobile terminal be configured to periodically to report DRB2, DRB3 and DRB4 each via
The downlink transmission rate or the PDCP data packet numbers for receiving of WLAN transmission, the cycle for reporting is 10
Second.Mobile terminal is receiving this with postponing, and measured and reported DRB2, DRB3 and DRB4 every 10 seconds
The downlink transmission data rate transmitted via WLAN or the PDCP data packet numbers for receiving.Wherein,
The specific report cycle of mobile terminal can adopt different realization mechanisms, can be by DRB2 and DRB4
Report cycle be set to 10 seconds, or the report cycle of DRB3 is set to into 1 second.
Such as, report condition is reporting for event triggering, and such as DRB2, DRB3 or DRB4 is via WLAN
The downlink transmission rate of transmission is less than predetermined thresholding, wherein, the thresholding can be 0, i.e., via WLAN
When the downlink transmission rate of transmission is 0, mobile terminal needs to base station to report.Or DRB2, DRB3
Or the downlink transmission rate that DRB4 is transmitted via WLAN is higher than predetermined thresholding, mobile terminal need to
Base station reports.
In being embodied as, mobile terminal can be reported to base station in PDCP layers, it is also possible to wirelessly provided
Source control (Radio Resource Control, RRC) layer reports the downlink transmission rate to base station or connects
The PDCP data packet numbers for receiving.
It should be noted that generally mobile terminal needs to judge whether the reference of main plot when measurement is performed
Whether signal reception power (Reference Signal Receiving Power, RSRP) value is less than S-measure.
When only RSRP values are less than S-measure, mobile terminal just can perform measurement to neighbor cell.But,
When mobile terminal is in LTE and WLAN converges state, when the RSRP values of main plot are higher than
S-measure, mobile terminal may not be to the downlink transmission rate that transmits via WLAN or downlink datas
Bag quantity is measured, and is also not carried out the related measurements of the WLAN of base station configuration.
In order to avoid it is above-mentioned the occurrence of, it is desirable to mobile terminal perform base station configuration WLAN it is related
Measurement when ignore S-measure, i.e., no matter whether the RSRP values of main plot are both needed to less than S-measure
The measurement of the WLAN correlations performed by base station configuration.
Step S302：According to the information of the downlink transmission rate of the carrying of the mobile terminal reporting, analysis
Obtain the information that different non-MCG carry the downlink transmission rate and propagation delay time transmitted via WLAN.

During fruit, can with reference to the historical information of own schedule, storage (buffer) historical information and WT can
The transmission state information that can be provided, such as certain PDCP PDU reach the initial time of Buffer and are somebody's turn to do
Size of PDU etc., obtains respective downlink transmission rate and the transmission of all carryings that mobile terminal is set up
The information of time delay.Afterwards, base station can be according to analysis result, it can be determined that corresponding non-MCG is carried and is
The demand of the no service quality for meeting the carrying.For example, base station can be according to the DRB2 of mobile terminal reporting
Via WLAN transmit the PDCP data packet numbers (periodically reporting) for receiving, calculate via
The downlink transmission rate of WLAN transmission, in the downlink transmission rate transmitted via LTE sides with reference to DRB2,
The total downlink transmission rates of DRB2 can be obtained.Then, then according to the QoS of DRB2, just can be true
Whether the downlink transmission data rate of DRB2 is determined less than the downlink transmission rate required by its QoS.
Step S303：Judge at least one in the downlink transmission data rate and propagation delay time of non-MCG carryings
Whether item is unsatisfactory for the requirement of the service quality that the non-MCG is carried；When judged result is to be, can hold
Row step S304, conversely, continuing to current transmission state.

It is when in propagation delay time, at least one is unsatisfactory for the requirement of the service quality that the non-MCG is carried, then non-to this
MCG is carried and is adjusted correspondingly.
Specifically, when it is determined that non-MCG carryings exceed via the propagation delay time of WLAN terminal transmission
During the corresponding upper rate limit threshold value of service quality that the non-MCG is carried, base station can notify the non-MCG
The PDCP entities of carrying reduce the speed to WT transmission datas；When it is determined that non-MCG is carried via WT
When the data transmission delay of transmission exceedes service quality that the non-MCG carries corresponding propagation delay time, to this
Carrying is reconfigured, and the type of carrying is revised as MCG carryings such as.
For example, when base station determines the downlink transmission data rate of DRB2 less than required by its service quality
Downlink transmission data rate when, base station can branch into DRB2 overabsorption transfer resources in LTE, with
Just DRB2 meets the demand of its service quality.When the downlink data transmission time delay of DRB4 is serviced higher than which
During the demand of the corresponding propagation delay time of quality, base station can be reconfigured to DRB4, such as by DRB4
Bearer types configuration carried by non-MCG and be configured to MCG carryings, serviced for which by base station, so as to completely
The demand of sufficient its service quality.
So, after above-mentioned adjustment, the carrying business in mobile terminal just can meet corresponding
The demand of service quality, can lift the service quality of carrying business, lift the experience of user.

The downlink transmission rate that some or all of Non-GBR is carried, so that all Non-GBR business
Transfer rate sum is less than or equal to the Aggregate Maximum Bit Rate.
For example, if the downlink transmission rate that total Non-GBR is carried is higher than AMBR, base station needs drop
The downlink data transmission amount of low some DRB, can such as reduce the data that DRB2 is transmitted in this base station
