Description

Base station and bearing service quality control method thereof

The present application is a divisional application of patent applications with an application date of 2015, 09/25, application number of 201510622364.8, entitled "base station and bearer service quality control method thereof".

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a base station and a method for controlling quality of bearer service thereof.

Background

Long Term Evolution (LTE) and Wireless Local Area Network (WLAN) Aggregation (LWA), which is a method for a mobile terminal (UE Termination, abbreviated as UE) to be configured by a base station to simultaneously use radio resources of LTE and WLAN for data transmission when the mobile terminal is in a radio resource control connection state (RRC Connected), at this time, the mobile terminal maintains RRC connection with the base station in LTE, a non-access stratum signaling of the mobile terminal is transmitted by the base station (an uplink non-access stratum signaling is transmitted to a core network by the base station, and a downlink non-access stratum signaling is transmitted to the mobile terminal by the base station). The mobile terminal in the invention supports the convergence of LTE and WLAN. The governing WLAN resources are called WLAN Terminals (WTs).

In LTE and WLAN Convergence, each downlink Packet Data Convergence Protocol (PDCP) Data Packet is generated by a PDCP entity located in a base station, and is transmitted to a mobile terminal through a Radio Link Control (RLC) layer or a Medium Access Control (MAC) layer of LTE or through a WLAN. Referring to fig. 1 and 2, in a coexistence scenario, a base station supporting LTE and WLAN convergence may be connected to a WT via an idealized or internal backhaul link. While in a non-coexistence scenario, base stations supporting LTE and WLAN convergence may connect with WTs over non-idealized backhaul links. Referring to fig. 1, in a coexistence scenario, a mobile terminal may establish multiple radio bearers, such as a Master Cell Group Bearer (MCG Bearer) that uses only LTE transmission resources for downlink data transmission; downlink data transmission simultaneously utilizes separate bearers (Split Bearer) of LTE and WLAN transmission resources; the downlink data transmission only utilizes a Switched Bearer (Switched Bearer) of the WLAN transmission resource, and a PDCP entity of the transferred Bearer is also positioned in a base station of the LTE system. For a separation Bearer or a transfer Bearer established by the mobile terminal, Data Radio Bearer (DRB) identification information of the Data needs to be inserted into a Data packet issued by the PDCP entity of the Bearer, so that the mobile terminal can distinguish Data packets of different bearers through the DRB identification. The processing of inserting the Data packet delivered by the PDCP entity into the Data Radio Bearer (DRB) identifier of the Data may be implemented by a newly introduced LWA Adaptation Layer (LWA Adaptation Layer), or implemented by an enhanced PDCP entity.

In the prior art, the WLAN does not adopt an Automatic Repeat Request (ARQ) mechanism, so the WLAN cannot provide very reliable data transmission, and may not ensure Quality of Service (QoS) requirements required by the bearer. For the bearers using WLAN resources for transmission, including Split Bearer (Split Bearer) and Switched Bearer (Switched Bearer), when the downlink data packet generated by the PDCP entity reaches the WLAN side, the scheduling of data transmission is performed by WLAN independent scheduling, which results in that the non-MCG bearers (i.e. Split Bearer and transferred Bearer) cannot meet the requirement of corresponding quality of service.

Detailed Description

For the downlink data transmission carried by the mobile terminal configured with LTE and WLAN convergence, the PDCP entity carried by the mobile terminal generates a PDCP data packet after encrypting and increasing the PDCP sequence number. If the bearer is a separated bearer, transmitting part of PDCP data packets of the bearer by the LTE side, and transmitting the rest part of PDCP data packets by the WLAN side; if the bearer is a transfer bearer, the PDCP packets of the bearer are all transmitted by the WLAN side. For a Data packet transmitted by the WLAN side, Radio Bearer (DRB) identification information of the Data needs to be inserted, so that the mobile terminal can distinguish the Data packets of different bearers through the DRB identification. The processing of inserting the PDCP Data packet into the Data Radio Bearer (DRB) identifier of the Data may be implemented by a newly introduced LWA Adaptation Layer (LWA Adaptation Layer), or implemented by an enhanced PDCP entity. In the prior art, for a Non-Master Cell Group (MCG) Bearer that utilizes WLAN resources to transmit, the MCG Bearer includes a Split Bearer (Split Bearer) and a Switched Bearer (Switched Bearer), when a downlink data packet (after adding a DRB identifier) generated by a PDCP entity arrives at a WLAN side, scheduling of data transmission is performed independently by the WLAN, which not only results in that the Non-MCG Bearer cannot meet a corresponding Quality of Service (QoS) requirement, but also may cause a sum of downlink data transmission rates of a Non-guaranteed Bit Rate (Non-GBR) Bearer established by a mobile terminal to exceed a requirement of an Aggregate Maximum Bit Rate (AMBR).

In order to solve the above problem, in the technical solution adopted in the embodiments of the present invention, a mobile terminal measures a data transmission rate transmitted via a WLAN and reports the measured data transmission rate to a base station, and the base station adjusts a bearer established by the mobile terminal according to a measurement result of the mobile terminal, so that each non-MCG bearer of the mobile terminal can meet a corresponding quality of service requirement and can meet an AMBR requirement of the mobile terminal.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 3 shows a flowchart of a bearer quality of service control method in an embodiment of the present invention. The bearer qos control method shown in fig. 3 may include:

step S301: and acquiring downlink transmission rate or data packet quantity information transmitted by the WLAN in the bearer measured and reported by the mobile terminal.

In a specific implementation, when the mobile terminal is in the LTE and WLAN convergence states and when a preset reporting condition is satisfied, the mobile terminal performs corresponding measurement on the downlink transmission rate or the number of data packets transmitted via the WLAN in the bearer created by the mobile terminal, and sends a corresponding measurement result to the base station serving the mobile terminal. The preset reporting condition may be a reporting condition preset by a protocol, or a reporting condition set by the base station through signaling.

The preset reporting condition may be that a preset periodic reporting time is reached, that is, the mobile terminal reports according to a preset reporting period. Wherein, the reporting periods of different non-MCG bearers may be the same or different. The preset reporting condition may also trigger reporting of the mobile terminal by a corresponding event, such as that a downlink transmission rate (i.e., a downlink data transmission rate) of the Split Bearer (Split Bearer) or the handover Bearer (Switched Bearer) transmitted via the WLAN (i.e., the downlink data transmission rate, since the RRC signaling and the non-access stratum signaling of the mobile terminal are not transmitted via the WLAN, the downlink transmission rate transmitted via the WLAN, i.e., the downlink data transmission rate, is lower than a predetermined first threshold (which may be 0) or higher than a predetermined second threshold, or when the number of downlink packet data convergence protocol data packets (PDCP PDUs) transmitted via the WLAN is lower than a preset first number threshold or higher than a preset second number threshold, the reporting is performed.

In a specific implementation, the threshold and the threshold may be preset by using a protocol, or may be set by the base station through signaling.

The mobile terminal may report independently for each Split Bearer and Switched Bearer according to a preset reporting condition, or report together. When the preset reporting specific case is configured by the base station, the base station can configure the mobile terminal to report the total data transmission rate of the plurality of bearers.

In a specific implementation, the downlink transmission rates of all bearers reported by the mobile terminal may be information of a sum of all downlink transmission rates transmitted through the WLAN, or information of downlink transmission rates of different non-MCG bearers, or information of a number of data packets transmitted through the WLAN within a preset time by each non-MCG bearer.

For example, when the mobile terminal is in LTE and WLAN convergence states, 4 bearer services, namely DRB1, DRB2, DRB3 and DRB4, are established in the mobile terminal. Wherein, the DRB1 is Guaranteed Bit Rate (GBR) service, and the base station is configured as an MCG bearer, that is, the base station is responsible for data transmission of the service. The DRB2 is a Non-GBR service, and the base station is configured as a Split Bearer, that is, the base station and the WLAN are responsible for downlink data transmission of the service, and the base station is also responsible for uplink data transmission. DRB3 is GBR traffic and the base station is configured as Split Bearer. The DRB4 is Non-GBR service, and the base station is configured as Switched Bearer, i.e. whether the WLAN is responsible for downlink data transmission of the service, or whether the base station is responsible for uplink data transmission.

For example, the mobile terminal is configured to periodically report the downlink transmission rate or the number of received PDCP data packets transmitted by the DRB2, DRB3, and DRB4 via the WLAN, where the reporting period is 10 seconds. After receiving the configuration, the mobile terminal measures and reports the downlink data transmission rate of the DRB2, DRB3 and DRB4 transmitted through the WLAN or the received PDCP data packet number every 10 seconds. The specific reporting period of the mobile terminal may adopt different implementation mechanisms, and the reporting periods of the DRBs 2 and the DRBs 4 may be set to 10 seconds, or the reporting period of the DRB3 may be set to 1 second.

For example, the reporting condition is event-triggered reporting, such as that the downlink transmission rate of the DRB2, DRB3, or DRB4 transmitted via the WLAN is lower than a predetermined threshold, where the threshold may be 0, that is, when the downlink transmission rate of the downlink transmission via the WLAN is 0, the mobile terminal needs to report to the base station. Or the downlink transmission rate of the DRB2, DRB3 or DRB4 transmitted via the WLAN is higher than a predetermined threshold, and the mobile terminal needs to report to the base station.

In a specific implementation, the mobile terminal may report the downlink transmission rate or the number of received PDCP data packets to the base station in a PDCP layer, or may report the downlink transmission rate or the number of received PDCP data packets to the base station in a Radio Resource Control (RRC) layer.

It should be noted that, in general, when performing measurement, the mobile terminal needs to determine whether a Reference Signal Receiving Power (RSRP) value of the primary cell is lower than S-measure. The mobile terminal performs measurement on the neighboring cell only if the RSRP value is lower than the S-measure. However, when the mobile terminal is in the LTE and WLAN convergence state, when the RSRP value of the primary cell is higher than S-measure, the mobile terminal may not measure the downlink transmission rate or the number of downlink packets transmitted via the WLAN, and may not perform WLAN-related measurements configured by the base station.

In order to avoid the above situation, the mobile terminal is required to disregard S-measure when performing the base station configured WLAN related measurements, i.e. the base station configured WLAN related measurements need to be performed regardless of whether the RSRP value of the primary cell is lower than S-measure or not.

Step S302: and analyzing and obtaining the information of the downlink transmission rate and the transmission delay of the WLAN transmitted by different non-MCG bearers according to the information of the downlink transmission rate of the bearers reported by the mobile terminal.

In a specific implementation, the downlink bearer data transmitted through the WLAN is generated by the corresponding PDCP entity in the base station and sent to the WLAN terminal, and the mobile terminal reports downlink data transmission information to the base station when receiving the downlink bearer data. Therefore, when receiving the measurement result sent by the mobile terminal, the base station may obtain information of respective downlink transmission rates and transmission delays of all bearers established by the mobile terminal, in combination with history information of its own scheduling, history information of stored (Buffer), and transmission state information that may be provided by the WT, such as starting time when a certain PDCP PDU reaches the Buffer, and size of the PDU. Then, the base station can determine whether the corresponding non-MCG bearer meets the requirement of the quality of service of the bearer according to the analysis result. For example, the base station may calculate the downlink transmission rate transmitted via the WLAN according to the number of received PDCP packets (periodic report) transmitted via the WLAN by the DRB2 reported by the mobile terminal, and may obtain the total downlink transmission rate of the DRB2 in combination with the downlink transmission rate transmitted via the LTE side by the DRB 2. Then, based on the QoS of the DRB2, it can be determined whether the downlink data transmission rate of the DRB2 is lower than the downlink transmission rate required by the QoS.

Step S303: judging whether at least one of the transmission rate and the transmission delay of the downlink data carried by the non-MCG does not meet the requirement of the service quality carried by the non-MCG; when the determination result is yes, step S304 may be executed, otherwise, the current transmission state is continuously maintained.

Step S304: and correspondingly adjusting the non-MCG bearer established by the mobile terminal.

In a specific implementation, when it is determined that at least one of a downlink transmission rate and a transmission delay of a non-MCG bearer transmitted via a WLAN does not meet a requirement of the service quality of the non-MCG bearer, the non-MCG bearer is adjusted accordingly.

Specifically, when it is determined that the transmission delay of the non-MCG bearer transmitted via the WLAN terminal exceeds the upper rate threshold corresponding to the service quality of the non-MCG bearer, the base station may notify the PDCP entity of the non-MCG bearer to reduce the rate of transmitting data to the WT; when determining that the transmission delay of data transmitted by the non-MCG bearer via the WT exceeds the transmission delay corresponding to the service quality of the non-MCG bearer, reconfiguring the bearer, such as modifying the type of the bearer to the MCG bearer.

For example, when the base station determines that the downlink data transmission rate of the DRB2 is lower than the downlink data transmission rate required for its service quality, the base station may allocate more transmission resources for the DRB2 in the LTE branch so that the DRB2 meets the requirement of its service quality. When the downlink data transmission delay of the DRB4 is higher than the requirement of the transmission delay corresponding to the service quality, the base station may reconfigure the DRB4, for example, configure the bearer type configuration of the DRB4 from a non-MCG bearer to an MCG bearer, and serve the MCG bearer by the base station, so as to meet the requirement of the service quality.

Therefore, after the adjustment, the bearer service in the mobile terminal can meet the requirement of the corresponding service quality, the service quality of the bearer service can be improved, and the use experience of a user can be improved.

In a specific implementation, the bearer qos control method as described in fig. 3 may further include:

step S305: and analyzing and obtaining the sum of the downlink transmission rates of all the non-guaranteed bit rate bearers in the bearer according to the information of the downlink transmission rate of the bearer reported by the mobile terminal. In a specific implementation, when the base station receives the measurement result sent by the mobile terminal, the base station may analyze and obtain the sum of the downlink transmission rates of all Non-GBR bearers in the mobile terminal by combining the historical information of its own scheduling and the historical information of the buffer.

Step S306: judging whether the sum of the downlink data transmission rates of all non-guaranteed bit rate bearers in the mobile terminal is greater than a preset maximum aggregation bit rate; when the judgment result is yes, step S306 may be performed; otherwise, the current transmission state is continuously maintained.

Step S307: and correspondingly adjusting the bearer established by the mobile terminal.

In a specific implementation, when the base station determines that the sum of the downlink transmission rates of all Non-GBR bearers established by the mobile terminal is greater than a preset AMBR (the value is provided by the core network), the base station may decrease the downlink transmission rates of some or all of the Non-GBR bearers so that the sum of the transmission rates of all Non-GBR traffic is less than or equal to the aggregated maximum bit rate.

For example, if the downlink transmission rate of the total Non-GBR bearer is higher than that of the AMBR, the base station needs to reduce the downlink data transmission amount of some DRBs, such as the amount of data transmitted by the DRB2 in the base station can be reduced, or the base station requires the PDCP entity of the DRB2 to reduce the amount of data transmitted to the WT.

The corresponding apparatus of the above method will be described in further detail below.
