And it can satisfy the demand of the AMBR of the mobile terminal.
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Fig. 3 shows the flow chart of one of embodiment of the present invention bearer quality of service control method.As shown in Figure 3
Bearer quality of service control method may include:
Step S301: it obtains mobile terminal and measure and in the carrying that reports via the downlink transmission rate or number of WLAN transmission
According to packet quantity information.
In specific implementation, when mobile terminal is in LTE and WLAN convergence state, when meeting preset report condition
When, mobile terminal can carry out the downlink transmission rate or data packet number in the carrying that it is created via WLAN transmission corresponding
Measurement, and corresponding measurement result is sent to the base station for servicing the mobile terminal.Wherein, preset report condition can be
The preset report condition of agreement is also possible to the report condition that base station is arranged by signaling.
Wherein, preset report condition can be to reach the preset periodic report time, i.e., mobile terminal is according to preset
Report cycle reports.Wherein, the report cycle of each different non-MCG carrying can be same or different.Preset upper tape
Part can also be triggered reporting for mobile terminal, such as division carrying (Split Bearer) or transfer carrying by corresponding event
Downlink transmission rate (the i.e. downlink transmission data rate, because not via WLAN that (Switched Bearer) is transmitted via WLAN
The RRC signaling and Non-Access Stratum signaling of the mobile terminal are transmitted, therefore refers to downlink via the downlink transmission rate that WLAN is transmitted
Message transmission rate) lower than scheduled first thresholding (thresholding can be 0), or it is higher than scheduled second thresholding, alternatively,
It can be via the quantity of the WLAN downlink grouped data convergence protocol data packet (PDCP PDU) transmitted lower than preset first number
Measure threshold value when, or be higher than preset second amount threshold when, execution reports.
In specific implementation, the threshold value and threshold value can be preset using agreement, or pass through signaling by base station
Setting.
Mobile terminal can be only for each Split Bearer and Switched Bearer according to preset report condition
It is vertical to report, it is also possible to report together.When it is described it is preset report specific case to be configured by base station when, base station can configure
The total message transmission rate of the multiple carryings of mobile terminal reporting.
In specific implementation, the downlink transmission rate of all carryings of mobile terminal reporting can pass to be all via WLAN
The information of the sum of defeated downlink transmission rate, perhaps for the information of the downlink transmission rate of each different non-MCG carryings or
Each non-MCG carrying is within a preset time via the quantity information of the data packet of WLAN transmission.
For example, 4 bearer services are established in mobile terminal when mobile terminal is in LTE and WLAN convergence state, point
It Wei not DRB1, DRB2, DRB3 and DRB4.Wherein, DRB1 is to guarantee bit rate (Guaranteed Bit Rate, GBR) industry
Business, base station are configured to MCG carrying, i.e., are transmitted by the data that the business is responsible in base station.DRB2 is Non-GBR business, base station configuration
For Split Bearer, i.e., it is responsible for the downlink data transmission of the business by base station and WLAN, upstream data is still responsible for by base station
Transmission.DRB3 is GBR traffic, and base station is configured to Split Bearer.DRB4 is Non-GBR business, and base station is configured to
Switched Bearer, i.e., be responsible for the downlink data transmission of the business by WLAN, and uplink is still responsible for transmission by base station.
For example, mobile terminal is configured as periodically reporting DRB2, DRB3 and DRB4 respectively via under WLAN transmission
Row transmission rate or the PDCP data packet number received, the period reported are 10 seconds.Mobile terminal is receiving this with postponing, often
It was measured every 10 seconds and reports DRB2, DRB3 and DRB4 via the WLAN downlink transmission data rate transmitted or the PDCP number received
According to packet quantity.Wherein, the specific report cycle of mobile terminal can use different realization mechanisms, can be by DRB2's and DRB4
Report cycle is set as 10 seconds, or sets the report cycle of DRB3 to 1 second.
For example, report condition is reporting for event triggering, the downlink transfer transmitted such as DRB2, DRB3 or DRB4 via WLAN
Rate is lower than scheduled thresholding, wherein the thresholding can be 0, i.e., when being 0 via the downlink transmission rate of WLAN transmission, move
Dynamic terminal needs to report to base station.Or the downlink transmission rate that DRB2, DRB3 or DRB4 are transmitted via WLAN is higher than scheduled
Thresholding, mobile terminal need to report to base station.
In specific implementation, mobile terminal can be reported at PDCP layers to base station, can also be in wireless heterogeneous networks
The PDCP data packet that (Radio Resource Control, RRC) layer reports the downlink transmission rate to base station or receives
Quantity.
It should be noted that usually mobile terminal needs to judge whether that the reference signal of main plot receives during measurement
Whether power (Reference Signal Receiving Power, RSRP) value is lower than S-measure.Only RSRP value is lower than
When S-measure, mobile terminal just can execute measurement to neighboring community.But when mobile terminal is in LTE and WLAN convergent manner
When state, when the RSRP value of main plot is higher than S-measure, mobile terminal may not be to the downlink transfer speed transmitted via WLAN
Rate or downlink data packet quantity measure, and will not execute the relevant measurement of WLAN of base station configuration.
In order to avoid the generation of above situation, it is desirable that mobile terminal is neglected when executing the relevant measurement of WLAN of base station configuration
Depending on S-measure, i.e., regardless of whether the RSRP value of main plot is lower than S-measure, it is required to execute the WLAN phase of base station configuration
The measurement of pass.
Step S302: according to the information of the downlink transmission rate of the carrying of the mobile terminal reporting, analysis obtains difference
Non- MCG carrying via the WLAN downlink transmission rate transmitted and propagation delay time information.
In specific implementation, because the downlink bearing data transmitted via WLAN is generated by PDCP entity corresponding in base station
And it is sent to WLAN terminal, and mobile terminal can be believed when receiving downlink bearing data to base station report downlink data transmission
Breath.Therefore, base station can combine historical information, the storage of own schedule when receiving the measurement result of mobile terminal transmission
(buffer) the transmission state information that historical information and WT may provide, as some PDCP PDU reaches the starting of Buffer
Time and the size of the PDU etc., when obtaining respective downlink transmission rate and the transmission for all carryings that mobile terminal is established
The information prolonged.Later, base station can be based on the analysis results, it can be determined that whether corresponding non-MCG carrying meets the clothes of the carrying
The demand for quality of being engaged in.For example, the PDCP number received that base station can be transmitted according to the DRB2 of mobile terminal reporting via WLAN
It (is periodically reported) according to packet quantity, calculates the downlink transmission rate transmitted via WLAN, DRB2 is being combined to transmit via the side LTE
Downlink transmission rate, the total downlink transmission rate of DRB2 can be obtained.Then, then according to DRB2 QoS, can determine
Whether the downlink transmission data rate of DRB2 is lower than downlink transmission rate required by its QoS.
Step S303: judge whether at least one of downlink transmission data rate and propagation delay time of non-MCG carrying are discontented with
The requirement of the service quality of the foot non-MCG carrying；When the judgment result is yes, step S304 can be executed, conversely, continuing to
Current transmission state.
Step S304: the non-MCG carrying established to the mobile terminal is adjusted correspondingly.
In specific implementation, when determine non-MCG carrying via in the WLAN downlink transmission rate transmitted and propagation delay time extremely
When one item missing is unsatisfactory for the requirement of the service quality of the non-MCG carrying, then the non-MCG carrying is adjusted correspondingly.
Specifically, being carried when the propagation delay time for determining that non-MCG carrying is transmitted via WLAN terminal more than the non-MCG
When the corresponding upper rate limit threshold value of service quality, base station can notify the PDCP entity of non-MCG carrying is reduced to WT to transmit number
According to rate；When the service quality for determining that non-MCG carrying is more than the non-MCG carrying via the data transmission delay that WT is transmitted is corresponding
Propagation delay time when, which is reconfigured, such as by the type of carrying be revised as MCG carrying.
For example, when base station determines the downlink transmission data rate of DRB2 less than downlink data required by its service quality
When transmission rate, base station can branch into DRB2 overabsorption transfer resource in LTE, so that DRB2 meets the need of its service quality
It asks.When the downlink data transmission time delay of DRB4 is higher than the demand of the corresponding propagation delay time of its service quality, base station can be right
DRB4 is reconfigured, and is such as configured MCG carrying by non-MCG carrying for the bearer types configuration of DRB4, is serviced by base station for it,
To meet the needs of its service quality.
In this way, the bearer service in mobile terminal can meet corresponding service quality after above-mentioned adjustment
Demand, the service quality of bearer service can be promoted, promote the usage experience of user.
In specific implementation, bearer quality of service control method as described in Figure 3 can also include:
Step S305: according to the information of the downlink transmission rate of the carrying of the mobile terminal reporting, analysis obtains described
The sum of the downlink transmission rate of all non-guaranteed bit rate carryings in carrying.In specific implementation, base station is receiving movement eventually
When holding the measurement result sent, it can be moved in conjunction with the historical information of own schedule and the historical information of buffer, analysis
The sum of the downlink transmission rate of all Non-GBR carryings in dynamic terminal.
Step S306: judge the sum of the downlink transmission data rate of non-guaranteed bit rate carrying all in mobile terminal
Whether preset maximum polymerization bit rate is greater than；When the judgment result is yes, step S306 can be executed；Conversely, continuing to tie up
Hold current transmission state.
Step S307: the carrying established to the mobile terminal executes corresponding adjustment.
In specific implementation, when base station determines the downlink transfer speed for all Non GBR carrying that the mobile terminal is established
When the sum of rate is greater than preset AMBR (value is provided by core net), base station can reduce some or all of Non-GBR carrying
Downlink transmission rate so that the sum of transmission rate of all Non-GBR business be less than or equal to the aggregate maximum bit
Rate.
For example, base station needs to reduce certain DRB's if the downlink transmission rate that total Non-GBR is carried is higher than AMBR
Downlink data transmission amount, for example the PDCP of data volume or base station requirement DRB2 that DRB2 is transmitted in this base station can be reduced
Entity reduces the data volume transmitted to WT.
The above-mentioned corresponding device of method will be further described in detail below.

Signaling is set.
In specific implementation, the preset report condition includes: to reach the preset periodic report time；It is passed via WLAN
