Specific embodiment
Fig. 1 is a kind of Signalling exchange schematic diagram in data transmission procedure in the prior art between UE and base station.Reference
Fig. 1, in LTE or 5G, UE access networks when there is data transfer demands are set up RRC and are connected with base station, and then set up data without
Line is carried, to transmit data.Specific data transmission procedure is as follows:
Step 101, UE sends RRC connection request signaling to base station.
UE initiates Stochastic accessing in the serving cells, and RRC connection request is sent during Stochastic accessing to base station.
Wherein, the base station can be the base station in LTE, it is also possible to the base station in 5G.
Step 102, base station sends RRC connections and sets up signaling to UE.
If Stochastic accessing success, base station can send RRC connections and set up signaling to UE.During RRC connections are set up,
Base station is configured with Signaling Radio Bearer (Signalling Radio Bearer, SRB) for UE.
Step 103, UE sends RRC connections and sets up completion signaling to base station.
The Non-Access Stratum signaling such as service request for completing to be sent comprising UE in signaling is set up in wherein described RRC connections.
Step 104, base station sends initial UE message to the mobile management entity (MME) in core net.
When the RRC connections that base station receives UE transmissions are set up completes signaling, suitable MME, Ran Houxiang can be selected for the UE
The MME of selection sends initial UE message.Wherein, the Non-Access Stratum signaling for being sent comprising UE in the initial UE message.The core of LTE
Heart net includes the network element such as MME and gateway;The core net of 5G includes the new network element for introducing.
Step 105, MME sends initial context and sets up demand signalling to base station.
MME knows that UE needs to set up Data Radio Bearer to transmit data according to the Non-Access Stratum signaling for receiving, therefore
MME sends initial context and sets up demand signalling to base station.Wherein described initial context is set up in request to include to be needed to set up
Bearing parameter, security configuration parameter etc..
Step 106, base station sends safe mode command to UE.
After base station receives the initial context foundation request of MME transmissions, bearing parameter, the security configuration for needing to set up are obtained
Parameter etc., and then base station controls itself in safe mode, and safe mode command is sent to UE so that UE is similarly in safety
Pattern.
Step 107, UE sends safe mode and completes signaling to base station.
The parameters such as the algorithm in UE application security mode commands, adjust and itself are in safe mode, and send peace to base station
Syntype completes signaling.
Step 108, base station sends RRC connections and reconfigures signaling to UE.
Base station performs RRC connection reconfiguration courses, and sending RRC connections to UE reconfigures signaling to notify that UE needs to set up
The parameter configuration such as Data Radio Bearer and measurement configuration.
Step 109, UE sends RRC connections and reconfigures completion signaling to base station.
The parameter configuration that the RRC connections that UE applications are received are included in reconfiguring, reconfigures RRC connections, and send RRC companies
Connect and reconfigure completion signaling to base station.
Step 110, base station sends initial context and sets up completion signaling to MME, notifies that MME is carried and has built up.
Step 111, can start the downstream transmission of data between UE and base station and MME.
Under normal circumstances, after data transfer is finished, base station will discharge the RRC connections of UE to UE, UE is entered Idle state.This
Afterwards, if UE needs page data again, the process of 101 to the step 111 that needs to repeat the above steps causes signaling consumption very
Greatly, the efficiency of data transfer is substantially reduced.
In order to save signaling consumption, the efficiency of transmission of data is improved, inactive state is introduced in 5G, but does not provide UE and exist
The related art scheme carried out data transmission with base station under inactive state.
Regarding to the issue above, The embodiment provides a kind of data transmission method, methods described is applied to non-sharp
Data are transmitted between user terminal and base station under state living.Specifically, UE first judges whether itself needs before the first data are sent
Connected state is switched to, oneself state is adjusted further according to judged result, finally send described the to base station with the state after adjustment
One data, it is possible thereby to realize the transmission of the upstream data between UE and base station.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment explain.
Reference picture 2, the embodiment of the invention provides a kind of transmission method of data, and methods described is applied under inactive state
UE and base station between transmit data.In specific implementation, base station can indicate UE by way of sending RRC signaling to UE
Into inactive state.Base station can also be the restricted area of the UE configuration inactive states of application, such as, one or more cells.UE
Inactive state can be applied in the restricted area that base station is configured, once UE leaves restricted area, UE need to notify base station or
Person voluntarily switches to Idle state.
Can be adopted under inactive state, between UE and base station and transmit upstream data with the following method:
Whether step 21, the UE judges itself need to switch to connected state before the first data are sent.
When UE be in inactive state when, to base station send the first data before, it is necessary to judge whether itself needs the company of switching to
Connect state.
In specific implementation, can judge itself whether need to switch to connected state using various ways.Of the invention
In one embodiment, can be by judging whether the data volume of first data judges more than default first data-quantity threshold
Whether itself will switch to connected state.Wherein, default first data-quantity threshold can be by those skilled in the art according to non-
The factor such as translational speed of the data transmission capabilities of UE, UE determines under activated state.That is, UE is before the first data are sent,
Needs determine the need for switching to connected state according to the data transmission capabilities under current state, translational speed.First data
Amount threshold value can be set by base station, or agreement can preset the threshold value, when the data volume of the first data is more than presetting the
During one data-quantity threshold, judge itself to need to switch to connected state.When the data volume of the first data is less than or equal to default first number
During according to amount threshold value, maintain from as inactive state.
It should be noted that in specific implementation, the first data-quantity threshold sheet is as one side dividing value.Described first
When the data volume of data is equal to first data-quantity threshold, the UE can be determined that itself to be needed to switch to connected state, also may be used
To judge that itself connected state need not be switched to.Specifically how to judge, can be by those skilled in the art's sets itself.But anyway
Judge, not enough into limitation of the present invention, and within protection scope of the present invention.
In another embodiment of the invention, the UE is judged by judging whether first data are continuously generated
Itself whether need to switch to connected state.When the first data can be continuously generated, such as UE can periodically generate the first data, this
When UE judge itself to need to switch to connected state, otherwise UE maintains inactive state.
Step 22, the UE adjusts the state of itself according to judged result, and is sent out to the base station with the state after adjustment
Send first data.
In specific implementation, when UE judges that itself needs to switch to connected state, then after itself being switched into connected state, with
Connected state sends the first data to the base station.Wherein, UE needs to be handed over base station during switching to connected state by current state
Mutual signaling, obtain after the confirmation of base station could successful switch to connected state.When UE is maintained from as inactive state, with inactive
State sends the first data to base station.
In specific implementation, no matter the UE is in connected state or inactive state, in order to the treatment for reducing base station is complicated
Degree and raising efficiency of transmission, UE after uplink synchronous are obtained, then can send first data to the base station.Also
It is to say, before first data are sent, UE can be obtained and the uplink synchronous between the base station.UE obtains uplink synchronous
The first data are retransmited afterwards, can be enabled that the signal of UE transmissions is complete and be fallen in the reception window of base station.Certainly, in UE
When only needing to send low volume data, UE can send the signal of information redundancy to base station, and base station only needs to receive in reception window
Part signal can solve the data of UE transmissions, and be obtained and the uplink synchronous between base station before need not sending the first data.
It is understood that specifically before the first data are sent, whether UE obtains the uplink synchronous and base station between, not paired enough
Limitation of the invention, and within protection scope of the present invention.
In one embodiment of this invention, when UE send the first data before not with base station uplink synchronous when, Ke Yiyou
Before base station sends the first data under the inactive states of UE, corresponding shared data is configured by system message or dynamic dispatching and is passed
Defeated resource so that the UE can utilize the shared data transmission resource being pre-configured with, in situation not with base station uplink synchronous
The first data of lower transmission.Wherein, the shared data transmission resource can by base station according in inactive state UE quantity with
And the water load equality factor of current area is configured, and is not restricted specifically, as long as UE can utilize the shared data transmission
The data of resource transmission first.During dynamic dispatching configuration shared data transmission resource, physical down control can be passed through by base station
Signaling processed indicates the shared transfer resource.
In specific implementation, in order to avoid wasting Internet resources, after first data are sent to base station with connected state,
Whether UE can also judge need to transmit other data in Preset Time.When UE needs to transmit other data in Preset Time,
Then maintain, from as connected state, the request for switching to inactive state otherwise to be sent to base station, switched to according to by base station non-
The request of activated state notifies that UE enters inactive state.
Fig. 3 is the transmission method flow chart of another data provided in an embodiment of the present invention.Reference picture 3, methods described can
To comprise the following steps:
Whether step 31, the UE judges itself need to switch to connected state before the first data are sent.
On step 31, the above-mentioned description on step 21 is specifically referred to, here is omitted.
Step 32, UE adjusts the state of itself according to judged result.
In specific implementation, when UE judges that itself needs to switch to connected state, then (UE after connected state itself will be switched to
Whether switching to connected state needs to obtain the confirmation of base station), otherwise maintain from as inactive state.
Step 33, obtains and the uplink synchronous between the base station.
In specific implementation, can be obtained using various ways and the uplink synchronous between base station, be not restricted specifically.
In one embodiment of this invention, can be obtained and the base station between by way of initiating Stochastic accessing
Uplink synchronous.
Specifically, when UE is maintained from as inactive state, can be sent to the base station during Stochastic accessing
The identification information of itself, base station can be in the UE distribution by dynamic dispatching after the identification information for receiving the UE
Row transfer resource so that the UE can utilize distributed uplink transmission resource to send the first data to base station.In the first number
After according to end of transmission, the UE can again interrupt the communication and base station between, and remain under inactive state.Wherein, it is described
The identification information of UE is sent by the MSG3 in random access procedure.
When UE switches to connected state, the identification information of itself can be sent to the base station during Stochastic accessing
And the information that RRC connections recover, recover and the RRC connections between the base station, while obtaining up and the base station between
It is synchronous.Wherein, the information that the identification information of the UE and RRC connections recover can be by the MSG3 in random access procedure (i.e.
Article 3 signaling) send.
Step 34, first data are sent with the state after adjustment to the base station.
In specific implementation, when UE judges that itself needs to switch to connected state, then after itself being switched into connected state, with
Connected state sends the first data to the base station.When UE is maintained from as inactive state, the is sent to base station with inactive state
One data.Wherein, UE sends connection and recovers message and obtain base station when connected state is switched to by current state, typically in UE
After confirmation, connected state is just switched to.
Fig. 4 is another data transmission method provided in an embodiment of the present invention, and methods described is equally applicable to inactive state
Under user terminal and base station between transmit data.In specific implementation, base station can be by the side to UE transmission RRC signalings
Formula, indicates UE to enter inactive state.Base station can also be the restricted area of the UE configuration inactive states of application, such as, one or many
Individual cell.UE can apply inactive state in the restricted area that base station is configured, once UE leaves restricted area, UE needs logical
Know base station or voluntarily switch to Idle state.
Under inactive state, can adopt and transmit downlink data with the following method:
Step 41, when the notification message of the transmission data that the base station sends is received, UE sends phase to the base station
The feedback message answered.
Wherein, whether the identification information of the UE can be included in the notification message and the UE is indicated in current state
Receive the configured information of the second data.
When base station needs to send data to the UE under inactive state, the notice of transmission data is first sent to the UE
Message.UE sends corresponding feedback message when the notification message is received to the base station.
In specific implementation, the notification message can be the message of bearing call signaling, or what is newly introduced disappears
Breath, is not restricted specifically.
In the notification message, whether base station can indicate UE current by the configured information using various ways
State receives the second data.In one embodiment of this invention, it is described to indicate whether the UE receives the second data in current state
What configured information can be determined by base station according to the data volume size of second data, such as, when the number of second data
During according to amount more than default second data-quantity threshold, indicate the user terminal that institute is received under connected state by the configured information
The second data are stated, otherwise indicates the user terminal that second data are received under current state.
Wherein, default second data-quantity threshold can be by those skilled in the art according to the data of UE under inactive state
The factors such as transmittability determine.That is, base station before the second data are sent to UE, it is necessary to number according to UE under current state
Indicate whether UE needs to switch to connected state according to transmittability.
It should be noted that in specific implementation, the second data-quantity threshold sheet is as one side dividing value.Described second
When the data volume of data is equal to second data-quantity threshold, base station can indicate UE to receive the second data in current state, also may be used
To indicate UE to receive the second data in connected state.Specifically whether indicate UE that the second data are received under current state, can be by ability
Domain personnel's sets itself.But indicate anyway, not enough into limitation of the present invention, and protection scope of the present invention it
It is interior.
Step 42, UE receives second data that the base station sends according to the feedback message.
In specific implementation, no matter the UE is in connected state or inactive state, and UE would generally first obtain uplink synchronous,
The second data are sent to base station so that what the signal that UE sends can be complete falls in the reception window of base station, reduce base station again
Treatment complexity and raising efficiency of transmission.Certainly, in the case where ensureing effectively to receive, UE need not be obtained and base station in advance
Between uplink synchronous, now, the feedback message is the configured information that the user terminal sends when up asynchronous, base
Stand and can know that UE need not obtain uplink synchronous and data can be transmitted according to the feedback message.Such as, UE can send letter
The signal of redundancy is ceased to base station, it is only necessary to which part signal just can obtain complete information by the reception window reception of base station, base station.
It is understood that specifically before the second data are received, whether UE obtains the uplink synchronous and base station between, not paired enough
Limitation of the invention, and within protection scope of the present invention.
In one embodiment of this invention, the UE can send feedback message by Stochastic accessing to the base station, also
Can be obtained by Stochastic accessing and the uplink synchronous between the base station, i.e., in the base station send feedback information and acquirement
Row is synchronous to be carried out simultaneously.When base station finds that UE needs to obtain uplink synchronous, that is, think that UE is fed back.Afterwards, base station can
Signalling exchange is carried out with the UE, after the UE obtains uplink synchronous, then the second data is sent to the UE.
In one embodiment of this invention, before UE of the base station under to inactive state sends the second data, can be advance
It is configured to carry the particular sequence of the feedback message by system message or the notification message.When UE need not be obtained
During uplink synchronous between base station, configured particular sequence can be passed through to described after the notification message is received
Base station feedback, the base station after the feedback for receiving UE, by the second data is activation to the UE.Wherein, the particular sequence
Can be the reference signals such as Preamble (i.e. particular sequence), not be restricted specifically, as long as the feedback information can be fed back
To the base station.
In specific implementation, base station can simultaneously configure multiple particular sequences for the feedback of UE, it is also possible to only configure one
Individual particular sequence is used for the feedback of UE.When base station is configured with multiple particular sequences is fed back for UE, base station is except described logical
Know whether the mark and the UE of instruction UE in message are received outside the second data in current state, also need to indicate the mark of these sequences
Know.If base station only configures a particular sequence fed back for UE, base station need not indicate the spy in the notification message
The mark of sequencing row, need to only indicate whether the mark and the UE of UE receive the second data in current state.
When the current state of UE is inactive state, that is, UE is indicated to receive the second data in inactive state, UE can be random
Send the identification information of itself during access to the base station by MSG3, base station is receiving the identification information of the UE
Afterwards, the second data can be sent to the UE by descending scheduling.
When the current state of UE is connected state, that is, UE is indicated to receive the second data in connected state, UE can be in Stochastic accessing
During by MSG3 to the base station send itself identification information and RRC connect recover information, recover and the base
Between standing RRC connection, and then UE obtain and the base station between uplink synchronous after, to the UE send the second data.
Fig. 5 is a kind of data transmission method provided in an embodiment of the present invention, and methods described may include steps of:
Whether step 51, the UE judges itself need to switch to connected state before the first data are sent.
Step 52, the UE adjusts the state of itself according to judged result, and is sent out to the base station with the state after adjustment
Send first data.
