Description

A kind of triggering method of Buffer Status Report, device, terminal
Technical field
The present invention relates to communication engineering field, more particularly to a kind of triggering method of Buffer Status Report, device, end End.
Background technology
In long term evolution (Long Term Evolution, referred to as LTE) system, terminal establishes Data Radio Bearer When (Data Radio Bearer, DRB), base station can distribute the DRB logic channels (Logical Channel, LC) of ownership, And logic channel group (Logical Channel Group, LCG), LCG have 0,1,2,3 totally four groupings at present.In connection When the terminal of state needs to send upstream data, if not enough ascending resource or mandate, first buffering area can be sent to base station It is big to carry ready buffered data information, that is, buffered data on LCG for state report (Buffer Status Report, BSR) Small (Buffer Size, BS) corresponding index value.Base station receives the index value that rear basis receives and knows buffered data size to eventually End configures corresponding uplink authorization, and terminal, which receives uplink authorization, can send upstream data.BS includes corresponding DRB on LCG In buffered data, packet data convergence (the Packet Data of wireless spread-spectrum technology (Radio Link Control, RLC) layer Convergence Protocol, PDCP) layer buffered data.
In order to allow base station to know in time, terminal has been already prepared to the BSR that will be sent, and defines following triggering BSR Event:Upstream data, which is reached, to be reached or comprising the data than current ready data higher priority currently without any standard The data got ready, receive ascending resource distribution and the byte filled is equal to or more than BSR (including head), BSR cycle timers Time-out retransmits BSR timer expiries and currently has ready data.When above several events occur, BSR can be triggered, Terminal will send BSR to base station after having uplink authorization.
In order to meet the following higher that can be predicted, faster, newer communication requirement, industry set about expansion to not Carry out the research of 5G technologies.5G will be in the handling capacity of bigger, more user's connections, more low time delay, higher reliability, more low-power consumption Further technical research is carried out in terms of (including network side equipment and user terminal).Currently, industry proposes 5G technical goals: The year two thousand twenty or so is arrived, realizes that the mobile data flow per 1000 times of region increases, per user equipment (User Equipment, UE) 10 to 100 times of handling capacity increases, the growth of 10 to 100 times of number of devices of connection, the longer cell life that 10 times of low-power equipment, And the decline of end-to-end 5 times of delays.For the angle of application scenarios, 5G will be supported using a unified Technical Architecture Enhance mobile broadband (enhanced Mobile broadband, eMBB) business, magnanimity machine type (massive Machine Type Communication, mMTC) business and highly reliable low time delay (Ultra Reliable and Low Latency) industry Business.Requirement of the different business to service quality (Quality of Service, QoS) is different.
In LTE system, unit, such as Fig. 1 are handled as minimum QoS when the data transmission of QoS frameworks to carry (bearer) The structural schematic diagram that QoS processing carries out data transmission is executed to carry granularity in LTE.Fig. 1 exemplary user equipment (UE) and The feelings of a PDN connection (PDN connection) are established between packet data network (Public Data Network, PDN) Condition, to serve the business with different QoS requirements in the PDN connections, core net can be in UE and PDN Gateway (PDN Gateway, P-GW) between establish the carrying of multiple evolved packet systems (Evolved Packet System bearer, EPS Bearer), one or more data service streams (service traffic flow, SDF) are carried on each EPS bearer, are held One or more SDF on an EPS bearer is loaded in by QoS having the same.EPS bearer are between UE and P-GW End-to-end logical bearers, EPS bearer correspondence establishments on three network interfaces passed through in LTE network framework Three sections of carryings, including the S5 and S8bearer on P-GW and gateway (Serving Gateway, S-GW) interface are established, Establish the data of S1-bearer on S-GW and base station (eNB) interface and foundation between eNB and UE in air interface without Line carries (Data Radio Bearer, DRB), and wherein S1-bearer and DRB are defined as between UE and S-GW again together The universal land radio access web carrying (E-UTRAN Radio Access Bearer, E-RAB) of evolution.EPS bearer's The mapping relations of foundation and SDF and EPS bearer, completely by core net decision and control, core net establishes EPS bearer When, it is notified that the qos parameter of each E-RAB of eNB (i.e. one section carryings of the EPS bearer in the sides E-URTAN), eNB can only be passive Receive or break off relations, if received, the DRB between UE is established on corresponding interface in the air, and according to the E-RAB received The qos parameter of rank carries out data dispatch transmission.
In dual link (Dual Connectivity), terminal can keep connecting with more than two network nodes simultaneously, But control plane connection only connect with one of cell such as macrocell, for example for, UE be in simultaneously cell 1 and In the coverage area of cell 2,1 attributive eNB 1 of cell is macro base station, and 2 attributive eNB 2 of cell is small-cell base station, when using doubly-linked When connection technology, UE keeps connection such as control plane to link with cell 1, can also include user plane link, meanwhile, UE is protected with cell 2 It holds connection such as user plane to link, i.e. UE is established with cell 1 and cell 2 simultaneously radio bearer.In dual link, in order to preferably The load balancing between base station is carried out, and farthest optimizes local resource, introduces segmentation Data Radio Bearer, therefore, doubly-linked In connecing, there is segmentation Data Radio Bearer and non-segmentation Data Radio Bearer, non-data segmentation radio bearer can exist only in Master base station (Master eNB, MeNB) or prothetic group station (secondary eNB, SeNB), have altogether the data of three types without Line carries, and exists only in the Data Radio Bearer abbreviation MeNB carryings on MeNB, exists only in the Data Radio Bearer on SeNB Abbreviation SeNB carryings are existed simultaneously in the referred to as segmentation carrying (split carryings) of the Data Radio Bearer on MeNB and SeNB.For How upstream data is sent by MeNB and SeNB, i.e., how to distribute MeNB and SeNB and send ratio, and referred to as streamed data matches, For example the Deta bearer is sent on MeNB and all needs to send the Data Radio Bearer on 30%, SeNB of transmission data and all need to Want the 70% of transmission data.
In LTE system, the mapping relations between qos policy and parameter and SDF and carrying are controlled by core net completely, Base station can only passively accept or reject and establish DRB.In a wireless communication system, wireless interface is really to execute and meet QoS Key point, and in current QoS frameworks, base station can not adjust each DRB according to actual wireless load, radio link quality The SDF of upper mapping, therefore most can not efficiently execute QoS.In addition, core net and access net coupling are too strong, core net is repaiied Access net will be directly affected by, which changing, needs to make corresponding modification, cannot achieve the independent extension or evolution of core net and access net.
For the disadvantages described above for overcoming in 4G QoS frameworks, 3GPP proposes a kind of QoS based on stream in the design of 5G systems Framework.In the QoS frameworks based on stream, eliminate carrying between core net and wireless access network, but in the air on interface after It is continuous to remain DRB.But in the above QoS frameworks based on stream that propose at present of 3GPP, for the hair of Buffer Status Report It send, especially the triggering of Buffer Status Report, there has been no effective solution schemes.

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Base Embodiment in the present invention, those of ordinary skill in the art obtained without creative efforts it is all its His embodiment, shall fall within the protection scope of the present invention.
The embodiment of the present application can be in 5G systems, but are not limited to the system.Further, the embodiment of the present application is applied to base In on the QoS frameworks of stream, which may include RAN side apparatus (such as base stations 5G, base stations eLTE etc.) and terminal.In the application A kind of triggering method can run on the Buffer Status Report on above-mentioned framework is provided in embodiment, it should be noted that The running environment of the triggering method of the above-mentioned Buffer Status Report provided in the embodiment of the present application is not limited to above-mentioned framework.
The QoS frameworks based on stream that the embodiment of the present application described in detail below is applied, are illustrated in figure 2 based on stream The schematic diagram of QoS frameworks, 5G core nets (Core) are received from packet data network (for example, internet (Internet)) SDF (for example, interconnection protocol flow direction (IP Flow) between network), service quality stream (QoS Flow) is mapped to by SDF, such as Multiple SDF with same or similar qos requirement can be aggregated into a QoS Flow, naturally it is also possible to be by one SDF is mapped to a QoS Flow.Here, 5G core nets are according to the qos policy of core net, the QoS demand of SDF, the label of user About information etc. generates QoS rules (QoS rule), and completes the mapping of SDF to QoS Flow.5G core nets by with wirelessly connect Network (RAN) between control plane interface by the QoS characterisitic parameters in the QoS rule of its decision making be sent to RAN (such as The base stations 5G, base stations eLTE etc.), QoS Flow are sent to RAN by 5G core nets by the interface in the user plane between RAN, are being sent out Give the QoS for including QoS characterisitic parameters used in the data packet in the packet header for the data packet that each of RAN includes QoS flow It identifies (QoS ID).RAN is according to the QoS characterisitic parameters received from core net, in the packet header received from core net QoS ID, data packet is mapped on the DRB of air interface, the mapping between QoS Flow and DRB is completed.In this process In, the sides RAN can fully consider that the factors such as actual wireless load, radio link quality, decision are established DRB and determined QoS Mapping relations between Flow and DRB.
Embodiment one
Fig. 3 is the flow chart of the triggering method for the Buffer Status Report that first embodiment of the invention provides, such as Fig. 3 institutes Show, the triggering method of the Buffer Status Report includes:
Step S101:Terminal detects Data Radio Bearer DRB and services the mapping relations generation of quality stream QoS flow Variation;
Step S102:The terminal triggers the Buffer Status Report BSR.
According to above-mentioned triggering method, whether terminal is become by the mapping relations between detecting DRB and QoS flow Change, judges whether to trigger BSR, the triggering method of this BSR can make base station on the QoS frameworks based on stream, in time know BSR that terminal will be sent (namely terminal will send the details of data), can more effectively distribute resource in this way, full The different QoS requirement of sufficient different business.
The realization details of each step of the above method is as follows:
Terminal detects that the mapping relations of DRB and QoS flow change in step S101, i.e., first, terminal judges Whether the mapping relations of DRB and QoS flow change, and secondly, terminal judges the mapping relations hair of DRB and QoS flow Changing.It can for example be included at least in the BSR of the terminal triggering:The mapping relations of DRB and service quality stream change Before, the buffered data size BS information of the taken logic channel group LCG of DRB;Become with the mapping relations of DRB and service quality stream After change, the BS information of the taken LCG of DRB.The BS information for example may include:The corresponding index value of the BS.The terminal is touched For example can also include in the BSR of hair:In the taken LCG of DRB, the data that PDCP layers of packet data convergence, Radio Link control The data that data and media the intervention mac layer of rlc layer processed are not yet dispatched.
It should be noted that terminal detects that the mapping relations of DRB and QoS flow change, for example, can be divided into Lower two methods:
The first, explicit collocation method (Explicit Configuration).
In explicit collocation method, a possible realization method is:Terminal receives the RRC initial configurations life of base station transmission It enables;The terminal configures the DRB and services the mapping relations of quality stream according to the RRC initial configuration commands;The terminal Receive the RRC modification configuration orders of base station transmission;The terminal according to the RRC change configuration order, change the DRB and The mapping relations of service quality stream.When terminal changes configuration order according to the RRC, changes the DRB and service quality stream After mapping relations, the terminal detects that the mapping relations of DRB and QoS flow change.
Second, bounce technique (Reflective mapping).
In bounce technique, a possible realization method is:The terminal parses the downlink data of the BRD at the first moment The service quality flow identifier for including in packet, and generate DRB and service the first mapping relations of quality stream;When first mapping With DRB and when servicing the initial mapping relationship difference of quality stream, the terminal detects DRB and services the mapping of quality stream relationship Relationship changes.
Wherein, the initial mapping relationship for example may include:The terminal parses the downlink of the DRB at the second moment The service quality traffic identifier for including in data packet, and the initial mapping relationship generated;Second moment includes:The terminal prison At the time of measuring in the downlink data packet of DRB comprising service quality traffic identifier.Alternatively, the initial mapping relationship includes:It is described The initial mapping relationship that terminal is obtained by radio resource control RRC initial configuration commands.
Certainly, in bounce technique, also other realization methods, for example, periodically parsing the downlink data packet of the DRB In include QoS flow ID, and the mapping relations of the DRB and QoS flow of different cycles are generated, when the two neighboring period When mapping relations difference, the terminal detects that the mapping relations of DRB and QoS flow change.
The terminal triggers BSR in step s 102, wherein triggering BSR refers to:So that terminal is carried out and sends BSR to base station Preparation BSR is sent to base station at once once meeting transmission condition.
In conjunction with step S101 and step S102, can be summarized as:Terminal judges whether the mapping relations of DRB and QoS flow are sent out Changing, when the mapping relations of DRB and QoS flow change, the terminal triggers BSR.And as a preferred option, Precondition for triggering BSR can also increase.
Increase by one:After terminal detects that the mapping relations of DRB and QoS flow change, it is also necessary to judge QoS Whether the logic channel group LCG of flow changes;When the LCG of the service quality stream changes, the terminal triggering The BSR.
Increase by two:After terminal detects that the mapping relations of DRB and QoS flow change, it is also necessary to described in judgement Whether the BS of the taken LCG of DRB changes;When the corresponding index values of the BS change, described in the terminal triggering BSR.It should be noted that BS changes, can be that the corresponding indexes of BS change.
Increase by three:After terminal detects that the mapping relations of DRB and QoS flow change, the terminal judges DRB Before changing with the mapping relations of service quality stream, the corresponding index values of BS of the LCG, and, DRB and service quality stream After mapping relations change, whether at least one is not 0 to the corresponding index values of BS of the LCG;The LCG before variation The corresponding index values of BS and the corresponding index values of the BS of the LCG after variation at least one when not being 0, the terminal triggering The BSR.
Increase by four:After terminal detects that the mapping relations of DRB and QoS flow change, it is also necessary to judge whether full The condition of sufficient at least one of:BS pairs of the taken LCG of DRB before the mapping relations of DRB and service quality stream change The corresponding index value of the BS is higher than after the index value answered changes less than thresholding 1, DRB with the mapping relations of service quality stream Thresholding 2;When meeting at least one of condition, the terminal triggers the BSR.
Increase by five:After the terminal detects that DRB changes with the mapping relations for servicing quality stream, it is also necessary to judge institute State whether DRB has data packet arrival;When the DRB has data packet arrival, the terminal triggers the BSR.
Increase by six:After the terminal detects that DRB changes with the mapping relations for servicing quality stream, it is also necessary to judge institute State the instruction whether terminal receives the triggering BSR that the base station is sent;When the terminal receives the triggering BSR that the base station is sent Instruction when, the terminal triggers the BSR;Wherein, the instruction of the triggering BSR is configured by RRC.
Increase by seven:After the terminal detects that DRB changes with the mapping relations for servicing quality stream, it is also necessary to judge institute State the instruction whether terminal receives the triggering BSR that the base station is sent;When the terminal receives the triggering BSR that the base station is sent Instruction when, the terminal triggers the BSR;Wherein, the instruction of the triggering BSR is configured by RRC.
It should be noted that also a kind of mode in the cards is:When terminal detect DRB be segmentation radio bearer, And the streamed data of the segmentation radio bearer matches when changing, the terminal triggers the BSR.
It is also to be noted that the mode that another possibility is realized is:Terminal has been set out after BSR, and is received After row resource, report BSR to base station, including the ready data of PDCP in LCG, the ready data of RLC, MAC are not yet dispatched Data.At this point, if a terminal detects that MAC has new data latency scheduling, then terminal triggers the BSR.
After step s 102, i.e., after terminal triggering BSR namely the terminal is carried out and sends BSR to base station After preparation, further include:After the terminal receives ascending resource, terminal sends the BSR to base station, and the base station is according to institute It is that the terminal is matched to state BSR (BSR carries the ready buffered data information i.e. corresponding index value of buffered data size on LCG) Set uplink authorization;After the terminal receives the uplink authorization, upstream data is sent to the base station.
So far, the process that terminal sends upstream data to base station is just completed, by the above method, terminal passes through detection Whether the mapping relations between DRB and QoS flow change, and judge whether to trigger BSR so that base station is in the QoS based on stream On framework, BSR that terminal has been ready for will sending (namely terminal will send the details of data) is known in time, Resource can be more effectively distributed in this way, meet the different QoS requirement of different business.
