Description

Method, user equipment and the base station of data transmission

Technical field

The present embodiments relate to the communications fields, and more particularly, to a kind of method of data transmission, user equipment And base station.

Background technique

Multiple logic channels of one user equipment (User Equipment, UE) are included into different logic channel groups The priority of (Logical Channel Group, LCG), base station each logic channel group when dispatching are different.UE reports caching shape When state reports (Butter Status Report, BSR), the outgoing data amount of each logic channel group is counted, is separately reported, supplied Do accurate scheduling decision in base station.If UE does not trigger BSR, but after discharging data packet, there are also some vacant wireless Resource, and data can not be put, UE can send truncated BSR Padding BSR at this time.If UE has multiple logics to believe at this time Road group has outgoing data, then UE sends truncated BSR to base station, wherein comprising highest priority and having that of outgoing data to patrol Collect the outgoing data amount of channel group；If only one logic channel group of UE has outgoing data at this time, UE is sent to base station Padding BSR, the outgoing data amount only comprising this logic channel group for having data.

UE sends BSR itself to base station and is also required to ascending resource, and base station is distributed ascending resource to UE at the time of needing, made It smoothly reports BSR.For this purpose, long term evolution (Long Term Evolution, LTE) system introduces scheduling request (Scheduling Request, SR) mechanism configures some SR resources for UE.These SR resources periodically occur, itself Very little.UE tells the base station side UE to have data to need to send by SR resource, to send as how many specific data, it is also necessary to BSR is indicated in detail.

The condition of some triggering BSR is defined in existing agreement, as long as meeting these conditions, UE triggers side BSR, triggering When, UE does not generate specific BSR, and until there is ascending resource, UE just counts the outgoing data amount of sending instant, BSR is generated, Issue base station.

The increase of development with mobile communication technology and the number using mobile data services, existing macrocellular are born It carries and increasingly weighs, in order to provide the user with better service, third generation partner program (the 3rd Generation Partner Project, 3GPP) introduce carrier wave polymerization (Carrier Aggregation, CA) technology.

In CA technology, multiple base stations can be used to provide service for the same UE, for example, by using micro-base station (Small Cell it) cooperates with macro base station (macro eNB) and provides service for UE.Here micro-base station is referred to as cell, such as can To be Home eNodeB (home eNB, HeNB), micro-base station (pico eNB), relay station (relay), remote radio (radio Remote head, referred to as: RRH) etc. transfer points, coverage area and transmission power are smaller, the wide coverage of macro base station And transmission power is larger.Functionally, macro base station can provide wide covering, be responsible for control signaling, and cell can then provide User data enhancing, is responsible for all or part of user service data.This mode can also be referred to as across station shunt mode.

It may result in base station hair due to there is multiple websites to provide uplink scheduling for UE across the UE under the shunt mode of station Uplink scheduling resource is sent, but UE has but needed the case where sending without upstream data, causes the waste of scheduling resource.

Fig. 2 a is the interaction diagrams of data of embodiment of the present invention transmission.One embodiment of the present of invention is as shown in Figure 2 a, Include:

The shunting service that 201a, UE receive first base station and the second base station provides.

In the embodiment of the present invention, first base station and the second base station provide data distribution service for UE, receive the upper line number of UE According to.Particularly, first base station is the data cached base station being used for transmission lower than the first buffer data size threshold value, in other words, First base station is for providing uplink scheduling when the data cached data volume of UE is less than the first buffer data size threshold value for UE.

Optionally, first base station is responsible for the ambulant base station of management UE, and in other words, first base station is control base It stands.First base station can be macro base station at this time, and the second base station can be the adjacent macro base station or first base station of first base station Micro-base station.

Alternatively, optionally, the second base station is responsible for the ambulant base station of management UE, i.e. the second base station is control base station. At this point, the second base station can be macro base station, first base station can be the adjacent macro base station or first base station of the second base station Micro-base station (cell).

No matter first base station is control base station or the second base station is control base station, UE receives control base station as UE configuration The first buffer data size threshold value.

In the embodiment of the present invention, it is to be directed to that the first buffer data size threshold value, which is a threshold value for UE whole installation, The data cached threshold value of all first business of UE.Optionally, the first business can be shunting business, at this time the first caching Data amount threshold values are directed to the data cached of all shunting business of UE.Alternatively, optionally, the first business may include shunting Business and non-shunting business, the first buffer data size threshold value is directed to the data cached of all business of UE at this time.Alternatively, can Selection of land, including the first business may include Signaling Radio Bearer (signaling radio bearer, SRB) data, or can not Including SRB data.Control base station be UE configure the first buffer data size threshold value when, can the threshold value according to as defined in agreement match It sets, is configured according to the data distribution strategy of operator, or determined according to factors such as channel qualities, specifically determining mode, The present invention is herein and with no restrictions.

Optionally, as be used for transmission data volume lower than the first buffer data size threshold value UE data cached base It stands, first base station is predetermined the base station of the base station that base station control base station determines or UE selection.In advance Determining base station can be and be previously determined to be macro base station, or is previously determined to be micro-base station.The base station that control base station determines, can To be the control base station base station specified when configuration shunts transmission, or it is determining according to factors such as channel conditions, network loads Base station.The base station of UE selection, can be the base station that UE shares according to CQI, QoS and meet the selections such as situation.

202a, UE compare the data cached data volume and the first buffer data size thresholding of all first business of UE Value.

If UE judges that the data cached data volume of current all first business of UE is greater than first buffer data size Threshold value is then executed referring to original shunt method, and details are not described herein by the present invention.If UE judges the current all caching numbers of UE According to data volume be less than the first buffer data size threshold value, then follow the steps 203a.Buffer data size is equal to corresponding The UE's of first buffer data size threshold value is data cached, a kind of optional scheme, can be considered greater than corresponding first caching number It is handled according to the case where amount threshold value；Another optional scheme, can be considered less than corresponding first buffer data size threshold value Situation processing.

203a sends low buffer data size to the second base station and indicates information.

The low buffer data size instruction information can indicate that all data cached data volumes of UE are lower than all cachings of UE First buffer data size threshold value of data, so that the second base station stops the data cached corresponding scheduling of resource to UE.

UE sends low buffer data size instruction information can be there are many mode.For example, first way, UE is directly to first Base station sends the low buffer data size instruction information.The second way, it is low that UE directly sends this to first base station and the second base station Buffer data size indicates information.The third mode, UE directly sends the low buffer data size instruction information to the second base station, and leads to It crosses the second base station and sends the low buffer data size instruction information to first base station.For the second base station, UE can directly to Second base station sends the low buffer data size instruction information, this can also be forwarded to deposit number at a low speed to the second base station by first base station Information is indicated according to amount.It optionally, can when UE forwards the low buffer data size to indicate information by first base station to the second base station (it can be X2 interface using the interface of first base station and the second base station, can be S1 interface, can also be connecing for other new definition Mouthful etc.) send the low buffer data size instruction information.

In the embodiment of the present invention, low buffer data size instruction information can be there are many manifestation mode.For example, sending caching number According to the BSR for 0, or define new media access control (Media Access Control, MAC) control element (Control Element, CE), specify new radio network temporary identifier (Radio Network Temporary Identity, RNTI) to mark Know pre- in the state that UE is currently at low buffer data size, or the subheader (sub-header) of utilization R/R/E/LCID message R bit is stayed to indicate that UE is currently at the state of low buffer data size, or utilizes the new definition in the PDCCH channel of physical layer Or it redefines or reserved bit etc. indicates the state etc. for being currently at low buffer data size.Alternatively, directly using glad Bit (happy bit) indicates that the second base station stops new uplink scheduling.

204a, UE can send the first BSR to first base station, so that first base station carries out uplink scheduling.

It should be noted that the present invention is not restricted to the execution sequence of step 203a and step 204a, for example, step 203a can also be carried out simultaneously before step 204a after step 204a, or with step 204a.

The uplink scheduling information of 205a, UE reception first base station.

206a, UE send the first upstream data to first base station according to uplink scheduling information, which includes that UE works as The preceding moment it is data cached.

Optionally, between step 204a corresponding first moment and step 206a corresponding second moment, if UE was once Through transmitting upstream data to the second base station, then UE, can be in the first upstream data when sending the first upstream data to first base station The 2nd BSR of middle carrying.2nd BSR is BSR of the UE before the second moment sent data.After first base station receives the 2nd BSR, Uplink scheduling information can be sent to UE according to the 2nd BSR, provide uplink scheduling for UE.

207a, UE compare all first business of the data cached data volume and UE of current all first business of UE Data cached corresponding second buffer data size threshold value.

Wherein, the second buffer data size threshold value can be the first buffer data size threshold value, is also possible to one and is greater than The value of first buffer data size threshold value.Similar with the first buffer data size threshold value, the second buffer data size threshold value is by controlling Base station configuration processed.Under default situations, if control base station does not configure the second buffer data size threshold value, it may be considered that using First buffer data size threshold value work judge, in other words, if control base station does not configure the second buffer data size threshold value, Then the second buffer data size threshold value is equal to the first buffer data size threshold value.

If the data cached data volume of all first business of UE is data cached less than all first business of UE Corresponding second buffer data size threshold value, thens follow the steps 205a.Meanwhile UE can choose to the second base station and send message, Also it can choose and do not send message to the second base station.If UE selects to send message to the second base station, UE can be to the second base station Sending indicates the data cached padding BSR for being 0, or defines a new MACCE, indicates remaining data by first base station Transmission.

If the data cached data volume of all first business of UE is data cached greater than all first business of UE Corresponding second buffer data size threshold value, thens follow the steps 208a.

The data cached of the UE of corresponding second buffer data size threshold value is equal to for buffer data size, it is a kind of optional Scheme can be considered processing the case where greater than corresponding second buffer data size threshold value；Another optional scheme, can be considered small It is handled in the case where corresponding second buffer data size threshold value.

Further, in step 207a, a timer can be added, for monitoring the slow of current all first business of UE The data volume of deposit data is greater than the duration of the second buffer data size threshold value.If current all data cached of UE Data volume is greater than being sustained for longer than or equal to scheduled time value, thening follow the steps for the second buffer data size threshold value 208a, it is no to then follow the steps 205a.If executing step 205a, UE can choose to the second base station and send message, can also be with Selection does not send message to the second base station.The scheduled time value can be base station according to carrier policy or network environment shape The time value that the factors such as condition determine, it is specific to determine the method present invention herein and with no restriction.When timer monitor continues Between when, for buffer data size be equal to corresponding second buffer data size threshold value UE a kind of data cached, optional side Case can be considered processing the case where greater than corresponding second buffer data size threshold value；Another optional scheme, can be considered and be less than The case where corresponding second buffer data size threshold value, is handled.By increasing the monitoring of time value, can avoid because of data burst thing The influence that moment flow wave zone caused by part comes.

Step 207a can be executed periodically, or triggered and executed according to certain event.

208a restores BSR trigger mechanism and/or the second base station to the data distribution transmission mechanism of UE.

Optionally, UE can send scheduling request information to the second base station, provide uplink scheduling to trigger the second base station for UE. For example, UE, which sends a SR to the second base station, requests the scheduling of the second base station, and current BSR is carried in subsequent ascending resource To the second base station.

Alternatively, optionally, UE sends instruction information to first base station, so that first base station notifies the according to the instruction information The uplink scheduling of two base stations participation UE.Wherein, instruction information instruction the data cached of UE is greater than the second buffer data size thresholding Value.For example, UE is notified the BSR of UE to second by the interface of first base station and the second base station by communicating first base station Base station.

Alternatively, optionally, UE sends the information that scheduling is assisted in the second base station of request to first base station, in order to first base station The second base station is notified to participate in the uplink scheduling of UE.

It is of course possible to which the present invention is herein with no restrictions there are also other modes for waking up the second base station.

It should be noted that restoring BSR trigger mechanism, there are many meanings, the first refers to restoring UE for pause data Second base station of transmission reports the trigger mechanism and its report mechanism of BSR, refers to restoring UE in configuration shunting business second When the BSR trigger mechanism and its report mechanism for first base station and the second base station, the trigger mechanism of BSR and its report Mechanism may be diversified, such as UE, only to control base station transmission BSR report, UE is respectively to first base station and the second base station The BSR of same content is sent, UE sends corresponding BSR of different data etc. to first base station and the second base station respectively, and the present invention exists This is with no restrictions.

Optionally, in the embodiment of the present invention, UE can be directed toward control base station and send BSR information.Control base station receives BSR After information, may be selected for BSR information to be transmitted to it is other provide the base station of point streaming service for UE, or provided to other for UE The base station of streaming service is divided to send the instruction information that control base station is generated according to BSR information.Fig. 2 b is number of the embodiment of the present invention According to the interaction diagrams of transmission.One embodiment of the present of invention is as shown in Figure 2 b, comprising:

The shunting service that 201b, UE receive first base station and the second base station provides.

In the embodiment of the present invention, first base station and the second base station provide data distribution service for UE, receive the upper line number of UE According to.Particularly, first base station is the data cached base station being used for transmission lower than the first buffer data size threshold value, or It says, first base station is used to be less than the data cached corresponding first buffer data size thresholding of UE when the data cached data volume of UE Uplink scheduling is provided when value for UE.

Optionally, first base station is responsible for the ambulant base station of management UE, and in other words, first base station is control base It stands.First base station can be macro base station at this time, and the second base station can be the adjacent macro base station or first base station of first base station Micro-base station (cell).

In the embodiment of the present invention, the first buffer data size threshold value be in UE each the first LCG it is data cached The threshold value of amount.Optionally, the first LCG refers to the LCG including shunting business, i.e., the first buffer data size threshold value is just in UE LCG comprising shunting business, not for the LCG not comprising shunting business.Alternatively, optionally, the first LCG may include comprising shunting The LCG of business and LCG not comprising the business of shunting, i.e. the first buffer data size threshold value is for all LCG in UE.Control base It stands when configuring the first buffer data size threshold value for the first LCG of UE, a correspondence can be separately configured for each the first LCG The first buffer data size threshold value, or be all first LCG configure a first unified buffer data size threshold value.It changes Sentence is talked about, and the data cached corresponding first buffer data size threshold value of all first LCG in UE can be identical, can also not Together.

The first targeted LCG's of first buffer data size threshold value is data cached, regardless of data cached in the first LCG It is the data cached of the data cached or non-shunting business of shunting business, all entire LCG is comprehensively considered, entire LCG Data cached corresponding the first buffer data size threshold value as a whole make comparisons.First buffer data size thresholding The first corresponding LCG's of value is data cached, it may include SRB data also may not include SRB data.The of each the first LCG One buffer data size threshold value may be the same or different.For example, it is assumed that it is respectively a, b and c that UE, which there are 3 LCG, correspond to The buffer data size threshold value of LCG be respectively a1, b1 and c1.Then buffer data size threshold value a1, b1 and c1 can be equal, It can not wait.

202b, UE compare the data cached data volume of the first LCG of each in UE and the first LCG corresponding first one by one Buffer data size threshold value.

It is data cached corresponding first data cached to compare the data cached data volume of the first LCG and the first LCG by UE When measuring threshold value, need to compare corresponding first data cached of data cached data volume of each the first LCG of UE Measure the relationship of threshold value.It is equal to the first LCG of corresponding first buffer data size threshold value for buffer data size, it is a kind of optional Scheme, can be considered greater than corresponding first buffer data size threshold value the first LCG processing；Another optional scheme, can The first LCG being considered as less than corresponding first buffer data size threshold value is handled, following to be related to sentencing for buffer data size threshold value It is disconnected, it is similar.At this point, UE comparison result can be divided into three kinds of situations: the first situation, the first LCG's of each of UE Data cached data volume is both less than its corresponding first buffer data size threshold value.Second situation, each of UE The data cached data volume of one LCG is both greater than its corresponding first buffer data size threshold value.The third situation, the portion in UE The data cached data volume of LCG is divided to be less than its corresponding first buffer data size threshold value.For the first case and third Kind situation, executes step 203b；It for second situation, is executed referring to original shunt method, details are not described herein by the present invention.

203b sends low buffer data size to the second base station and indicates information.Wherein, which refers to Show the data cached data volume of at least one LCG of UE lower than the first buffer data size door corresponding at least one LCG Limit value.

If belonging to the first situation, all LCG's of the low buffer data size instruction information instruction UE is data cached Data volume is below the first buffer data size threshold value corresponding to LCG, then the second base station can stop providing uplink scheduling for UE.

If belonging to the third situation, the part LCG's of the low buffer data size instruction information instruction UE is data cached Data volume is lower than the first buffer data size threshold value corresponding to LCG, at this point, since there are also part LCG needs to be transferred in UE Second base station, therefore the second base station also needs to provide uplink scheduling for UE.After UE receives the uplink scheduling information of the second base station, Upstream data can be transmitted to the second base station according to the priority of UE itself, the method for transmission is similar with original method, and the present invention exists This is repeated no more.

In the embodiment of the present invention, the low buffer data size instruction information is without explicitly pointing out part or all LCG Data cached data volume is lower than the first corresponding buffer data size threshold value, and the second base station is it is only necessary to know that some or all The data cached data volume of LCG is lower than the first corresponding buffer data size threshold value.

Optionally, if the buffer data size of each LCG of UE is both less than the first buffer data size door of corresponding LCG Limit value (the first situation), then the low buffer data size instruction information can be only comprising data cached state lower than the first caching number According to the instruction of amount threshold value.Alternatively, optionally, if there was only the of the buffer data size of part LCG less than corresponding LCG in UE One buffer data size threshold value (the third situation), which includes buffer data size less than corresponding The information of the LCG of the first buffer data size threshold value of LCG.For example, it is assumed that it is respectively a, b and c that UE, which has 3 LCG, it is corresponding The buffer data size threshold value of LCG is respectively a1, b1 and c1, then if the buffer data size of a, b and c to be respectively smaller than its corresponding First buffer data size threshold value a1, b1 and c1 of LCG, then the low buffer data size instruction information can be only comprising data cached State is lower than the instruction of the first buffer data size threshold value；If it is corresponding that the buffer data size of only a and b is respectively smaller than its The first buffer data size threshold value a1 and b1 of LCG, then low buffer data size instruction information includes that buffer data size is less than pair The information of a and b of the first buffer data size threshold value of the LCG answered.

UE sends UE in the mode and step 203a of low buffer data size instruction information and sends low buffer data size instruction letter The mode of breath is similar, and details are not described herein by the present invention.

In the embodiment of the present invention, low buffer data size instruction information can also be there are many manifestation mode.For example, sending caching The BSR that data are 0, the BSR indicate to be somebody's turn to do in UE lower than the buffer data size of the LCG of corresponding first buffer data size threshold value BSR may include the information of multiple LCG.Or new MACCE is defined, specify new RNTI to identify slow lower than corresponding first in UE The buffer status of the LCG of deposit data amount threshold value, the MACCE may include the information of multiple LCG.

204b, UE can send the first BSR to first base station, so that first base station carries out scheduling of resource.

It should be noted that the present invention is not restricted to the execution sequence of step 203b and step 204b, for example, step 203b can also be carried out simultaneously before step 204b after step 204b, or with step 204b.

In the embodiment of the present invention, the first BSR may include all lower than corresponding first buffer data size door in the LCG of UE The buffer data size of the LCG of limit value.

The uplink scheduling information of 205b, UE reception first base station.

In the embodiment of the present invention, which is for all lower than corresponding first caching number in the LCG of UE According to the uplink scheduling information of the LCG of amount threshold value.

206b, UE send the first upstream data to first base station according to uplink scheduling information, which may include UE Current time it is data cached.

Optionally, between step 204b corresponding first moment and step 206b corresponding second moment, if UE was once Through transmitting upstream data to the second base station, then UE, can be in the first upstream data when sending the first upstream data to first base station The 2nd BSR of middle carrying.2nd BSR is BSR of the UE before the second moment sent data.After first base station receives the 2nd BSR, Uplink scheduling information can be sent to UE according to the 2nd BSR, provide uplink scheduling for UE.

207b, UE compare the data cached data volume of each current the first LCG of UE and the caching of the first LCG one by one The corresponding second buffer data size threshold value of data.

Wherein, the second buffer data size threshold value can be the first buffer data size threshold value, is also possible to one and is greater than The value of first buffer data size threshold value.Similar with the first buffer data size threshold value, the second buffer data size threshold value is by controlling Base station configuration processed.Under default situations, if control base station does not configure the second buffer data size threshold value, it may be considered that using First buffer data size threshold value work judges that in other words, the second buffer data size threshold value is equal to the first buffer data size door Limit value.It is similar with the first buffer data size threshold value, the data cached corresponding second buffer data size door of each the first LCG Limit value may be the same or different.

The first LCG for buffer data size equal to corresponding second buffer data size threshold value, a kind of optional scheme, It can be considered that the first LCG greater than corresponding second buffer data size threshold value is handled；Another optional scheme, can be considered and be less than First LCG of corresponding second buffer data size threshold value is handled.

If each UE current the first LCG data cached data volume is both less than corresponding second caching of the first LCG Data amount threshold values then follow the steps 205b.Similar with step 207a, UE can choose to the second base station and send message, can also To select not send message to the second base station.If UE selects to send message to the second base station, UE can be sent to the second base station It indicates the data cached padding BSR for being 0, or defines a new MACCE, instruction remaining data is passed by first base station It is defeated.

If it is corresponding second data cached to be greater than the first LCG for the buffer data size of the first LCG some or all of in UE Threshold value is measured, then executes 208b.

Further, in step 207b, a timer can be added, it is data cached for monitoring the first current LCG of UE Data volume be both greater than the first LCG data cached corresponding second buffer data size threshold value duration.If in UE Data cached corresponding second caching number there are the data cached data volume of the first LCG of the UE greater than the first LCG of UE The case where according to amount threshold value, and it is sustained for longer than or is equal to scheduled time value, 208b is thened follow the steps, step is otherwise executed Rapid 205b.If if executing step 205b(is to be greater than to be somebody's turn to do there is no the data cached data volume of the first LCG of the UE in UE The case where data cached corresponding second buffer data size threshold value of UE or duration are less than scheduled time value), then UE can choose to the second base station and send message, also can choose and does not send message to the second base station.The scheduled time value, can It is specific to determine this hair of method to be a base station time value determining according to factors such as carrier policy or Network Environment Status It is bright herein and with no restriction.When the timer monitor duration, corresponding second buffer data size is equal to for buffer data size Each the first LCG's of threshold value is data cached, and a kind of optional scheme can be considered greater than corresponding second buffer data size The case where threshold value, is handled；Another optional scheme, the case where can be considered less than corresponding second buffer data size threshold value Processing.By increasing the monitoring of time value, the influence that moment flow wave zone comes caused by can avoid because of data emergency event.

Step 207b can be executed periodically, or triggered and executed according to certain event.

208b restores BSR trigger mechanism and/or the second base station to the data distribution transmission mechanism of UE

Alternatively, UE needs the instruction information assisted to control base station report, control base station wakes up the according to the instruction information Two base stations notify the second base station to provide uplink scheduling for UE.

Optionally, in the embodiment of the present invention, UE can be directed toward control base station and send BSR information.Control base station receives BSR After information, may be selected for BSR information to be transmitted to it is other provide the base station of point streaming service for UE, or provided to other for UE The base station of streaming service is divided to send the instruction information that control base station is generated according to BSR information.

Fig. 2 c is the interaction diagrams of data of embodiment of the present invention transmission.One embodiment of the present of invention is as shown in Figure 2 c, Include:

The shunting service that 201c, UE receive first base station and the second base station provides.

In the embodiment of the present invention, first base station and the second base station provide data distribution service for UE, receive the upper line number of UE According to.Particularly, first base station is the shunting industry for being used for transmission buffer data size and being lower than corresponding first buffer data size threshold value The data cached base station of business, in other words, first base station are used for when the data cached data volume of UE is data cached less than UE Uplink scheduling is provided when corresponding first buffer data size threshold value for UE.

In the embodiment of the present invention, the first buffer data size threshold value is to shunt the data cached of business for each in UE The threshold value of amount.It optionally, can be each when control base station is shunting business configuration the first buffer data size threshold value of UE A corresponding first buffer data size threshold value is separately configured in a shunting business, or is all shunting business needed to configure Configure a first unified buffer data size threshold value.In other words, each of UE shunts business corresponding first and delays Deposit data amount threshold value may be the same or different.

Optionally, as be used for transmission data volume lower than the first buffer data size threshold value UE data cached base It stands, first base station is predetermined the base station that base station control base station determines or UE is selected according to channel quality Base station.Predetermined base station can be and be previously determined to be macro base station, or is previously determined to be micro-base station.Control base station is true Fixed base station can be the control base station base station specified when configuration shunts transmission, or according to channel conditions, network load Etc. factors determine base station.The base station of UE selection, can be the base station that UE shares according to CQI, QoS and meet the selections such as situation.

202c, UE compare in UE data cached data volume that each shunts business and corresponding shunting business one by one First buffer data size threshold value.

UE compares the data cached data volume of shunting business and the data cached corresponding first caching number of the business of shunting When according to amount threshold value, need to compare the first corresponding caching number of the data cached data volume of each shunting business of UE According to the relationship of amount threshold value.It is equal to the shunting business of corresponding first buffer data size threshold value for buffer data size, it is a kind of Optional scheme can be considered the shunting business processing greater than corresponding first buffer data size threshold value；Another optional side Case can be considered the shunting business processing less than corresponding first buffer data size threshold value, following to be related to buffer data size thresholding The judgement of value, it is similar.At this point, UE comparison result can be divided into three kinds of situations: the first situation, each of UE is shunted The data cached data volume of business is both less than its corresponding first buffer data size threshold value.Second situation, it is every in UE The data cached data volume of one shunting business is both greater than its corresponding first buffer data size threshold value.The third situation, The data cached data volume that part in UE shunts business is less than its corresponding first buffer data size threshold value.For first Kind situation and the third situation execute step 203c；It for second situation, is executed referring to original shunt method, the present invention exists This is repeated no more.

203c sends low buffer data size to the second base station and indicates information.Wherein, which refers to Show that at least one data cached data volume for shunting business of UE is delayed lower than corresponding at least one shunting business first Deposit data amount threshold value.

If belonging to the first situation, the caching number of all shunting business of the low buffer data size instruction information instruction UE According to data volume be below the first buffer data size threshold value corresponding to shunting business, at this point, the second base station stop mentioned for UE For uplink scheduling.

If belonging to the third situation, the part of the low buffer data size instruction information instruction UE shunts the caching number of business According to data volume lower than the first buffer data size threshold value corresponding to shunting business.At this point, since there are also parts to shunt in UE Business needs to be transferred to the second base station, therefore the second base station also needs to provide uplink scheduling for UE.UE receives the second base station After uplink scheduling information, upstream data, the method for transmission and original side can be transmitted to the second base station according to the priority of UE itself Method is similar, and details are not described herein by the present invention.

Alternatively, UE does not distinguish above-mentioned two situations in detail, it is only necessary to indicate the data cached of at least N number of shunting business of UE Data volume lower than the first buffer data size threshold value corresponding at least one shunting business, N can be 1,2 here, 3 ..., N are default value or are configured by control base station.

In the embodiment of the present invention, UE sends UE in the mode and step 203a of low buffer data size instruction information and sends at a low speed Deposit data amount indicates that the mode of information is similar, deposits number at a low speed in the manifestation mode and step 203b of low buffer data size instruction information Manifestation mode according to amount instruction information is similar, and details are not described herein by the present invention.

204c, UE can send the first BSR to first base station, so that first base station carries out scheduling of resource.

It should be noted that the present invention is not restricted to the execution sequence of step 203c and step 204c, for example, step 203c can also be carried out simultaneously before step 204c after step 204c, or with step 204c.

In the embodiment of the present invention, the first BSR may include all lower than corresponding first caching number in the shunting business of UE According to the buffer data size of the shunting business of amount threshold value.

The uplink scheduling information of 205c, UE reception first base station.

In the embodiment of the present invention, which is for all slow lower than corresponding first in the shunting business of UE The uplink scheduling information of the shunting business of deposit data amount threshold value.

206c, UE send the first upstream data to first base station according to uplink scheduling information, which may include UE Current time it is data cached.

Optionally, between step 204c corresponding first moment and step 206c corresponding second moment, if UE was once Through transmitting upstream data to the second base station, then UE, can be in the first upstream data when sending the first upstream data to first base station The 2nd BSR of middle carrying.2nd BSR is BSR of the UE before the second moment sent data.After first base station receives the 2nd BSR, Uplink scheduling information can be sent to UE according to the 2nd BSR, provide uplink scheduling for UE.

207c, UE compare the data cached data volume of each current shunting business of UE one by one and shunt the slow of business The corresponding second buffer data size threshold value of deposit data.

Wherein, the second buffer data size threshold value can be the first buffer data size threshold value, is also possible to one and is greater than The value of first buffer data size threshold value.Similar with the first buffer data size threshold value, the second buffer data size threshold value is by controlling Base station configuration processed, similar with the first buffer data size threshold value, each shunts data cached corresponding second caching of business Data amount threshold values can be identical, can be different.Under default situations, if control base station does not configure the second buffer data size door Limit value, it may be considered that judged using the first buffer data size threshold value work, in other words, second buffer data size threshold value etc. In the first buffer data size threshold value.

It is equal to the shunting business of corresponding second buffer data size threshold value, a kind of optional side for buffer data size Case can be considered the shunting business processing greater than corresponding second buffer data size threshold value；Another optional scheme, can be considered Less than the shunting business processing of corresponding second buffer data size threshold value.

Delay if each UE current data volume for shunting service buffer data is both less than shunting business corresponding second Deposit data amount threshold value, thens follow the steps 205c.Similar with step 207a, UE can choose to the second base station and send message, It can choose and not send message to the second base station.If UE selects to send message to the second base station, UE can be sent out to the second base station Sending indicates the data cached padding BSR for being 0, or defines a new MACCE, and instruction remaining data is passed by first base station It is defeated.

If the buffer data size for shunting business some or all of in UE is greater than the corresponding second caching number of shunting business According to amount threshold value, 208c is thened follow the steps.

Further, in step 207c, a timer can be added, for monitoring the current shunting service buffer data of UE Data volume be greater than the corresponding second buffer data size threshold value of the shunting business duration.If existing in UE and shunting industry The data cached data volume of business is greater than the case where data cached corresponding second buffer data size threshold value of the shunting business And it is sustained for longer than scheduled time value, and 208c is thened follow the steps, it is no to then follow the steps 205c.If executing step 205c, then UE can choose to the second base station and send message, also can choose and does not send message to the second base station.When this is scheduled Between be worth, can be the time value that base station is determined according to factors such as carrier policy or Network Environment Status, it is specific to determine The method present invention is herein and with no restriction.When the timer monitor duration, it is slow that corresponding second is equal to for buffer data size The shunting business of deposit data amount threshold value, a kind of optional scheme can be considered greater than corresponding second buffer data size threshold value Shunting business processing；Another optional scheme, can be considered the shunting industry less than corresponding second buffer data size threshold value Business processing.By increasing the monitoring of time value, the influence that moment flow wave zone comes caused by can avoid because of data emergency event.

Step 207c can be executed periodically, or triggered and executed according to certain event.

208c restores BSR trigger mechanism and/or the second base station to the data distribution transmission mechanism of UE

In the present invention, UE can report BSR in several ways.UE reports the mode of BSR to be applicable to Fig. 2 a, Fig. 2 b, figure In embodiment shown in 2c.

One embodiment of the present of invention, UE can introduce one first instruction information in BSR, which is used to indicate It whether include the bit (bytes) that scheduling is crossed but do not obtained to other base station reports in current BSR.For example, one kind can be introduced The padding BSR of new type, the padding BSR indicate " once crossing but do not obtain the bit of scheduling to other base station reports ".Base Standing can avoid excessively authorizing according to the first instruction information.It further, can be in the interface between the base station for being responsible for shunting transmission Introduce interaction mechanism, and the remaining data of UE it is few (i.e. Fig. 2 a, Fig. 2 b, Fig. 2 c embodiment in it is data cached lower than first The case where measuring threshold value) when, the base station for being responsible for shunting transmission negotiates to be dispatched by which base station.

Further, second indication information can be also introduced, is used to indicate and above-mentioned " once crossed to other base station reports but do not obtain tune Whether the data volume size of the bit of degree " is greater than scheduled threshold value, to be responsible for the base station of transmission according to second indication information It is handled.

Another embodiment of the invention, UE encode BSR and data mixing when sending out data every time.Whether trigger BSR carries an easy BSR when uploading data every time.

Fig. 3 is the another method flow chart of data of embodiment of the present invention transmission.The method of Fig. 3 is executed by the second base station.

301, the low buffer data size that the second base station receives UE indicates information, and the low buffer data size instruction information is for referring to Show that the data cached data volume of user equipment (UE) is lower than the data cached corresponding buffer data size threshold value of the UE, this is at a low speed Deposit data amount instruction information is sent by the UE or the low buffer data size instruction information is sent by first base station.

302, the second base station stops providing uplink scheduling for the UE according to the low buffer data size instruction information.Wherein, should UE receives the shunting service of at least two base stations including the first base station and second base station, and the first base station is for working as Uplink is provided when the data cached data volume of UE is less than the data cached corresponding first buffer data size threshold value of UE for UE Scheduling.

In the embodiment of the present invention, the second base station indicates information by receiving the low buffer data size of UE, and at a low speed according to this Deposit data amount instruction information stops providing uplink scheduling for UE, and the waste for avoiding base station resource from dispatching improves the utilization of resource Efficiency.

In the embodiment of the present invention, UE receives the shunting service of at least two base stations including first base station and the second base station. When the data cached data volume of UE is less than the data cached corresponding first buffer data size threshold value of UE, first base station is UE provides uplink scheduling.In other situations, UE is subjected to the uplink scheduling of other base stations.

Optionally, when the low buffer data size instruction information is sent by first base station, the low buffer data size instruction letter Breath is sent by first base station by the interface of first base station and the second base station.

Optionally, as one embodiment, the second base station can receive the restoration schedule instruction information of UE transmission, the recovery Scheduling instruction information indicates that the second base station reverts to the UE and provides uplink scheduling.

Alternatively, optionally, as another embodiment, the restoration schedule that the second base station can receive first base station transmission refers to Show information, restoration schedule instruction information indicates that the second base station reverts to the UE and provides uplink scheduling.

Fig. 4 is the another method flow chart of data of embodiment of the present invention transmission.The method of Fig. 4 is executed by first base station.

401, first base station compares the data cached data volume of the UE and data cached corresponding first caching of the UE Data amount threshold values.

402, if the data cached data volume of the UE is less than data cached corresponding first buffer data size of the UE Threshold value, then the first base station sends low buffer data size to the second base station and indicates information.The low buffer data size indicates information Second base station is used to indicate to stop providing uplink scheduling for the UE.Wherein, user equipment (UE) receives to include first base station and the The shunting service of at least two base stations including two base stations, the first base station are used to be less than UE when the data cached data volume of UE Data cached corresponding first buffer data size threshold value when for UE provide uplink scheduling.

In the embodiment of the present invention, first base station by comparing the UE data cached data volume and the UE it is data cached Corresponding first buffer data size threshold value, and indicate that the second base station stops providing uplink scheduling for UE according to comparison result, it keeps away The waste for exempting from base station resource scheduling, improves the utilization efficiency of resource.

Optionally, first base station compares the data cached data volume of the UE and delays with data cached corresponding the first of the UE Deposit data amount threshold value can include: first base station compares the data cached data volume of the UE in the BSR for receiving the UE and is somebody's turn to do The data cached corresponding first buffer data size threshold value of UE；And/or first base station is for UE when that provides uplink scheduling ratio Compared with the data cached corresponding first buffer data size threshold value of the data cached data volume of the UE and the UE.

Optionally, which is control base station or second base station is the control base station.Wherein, the control base Station is the ambulant base station for being responsible for managing the UE at least two base station.
