Specific implementation mode
When UE needs on-demand system information, the scheduling information of the on-demand system information in current MSI is first checked
Indicate whether the on-demand system information needed for the UE is being broadcasted.If MSI indicates that the on-demand system information is not wide
It broadcasts, then sends the request message of the on-demand system information to base station, and after the request message for sending the on-demand system information, it can
To obtain required on-demand system information by monitoring the SI windows in the on-demand scheduling system information period.Base station is receiving
After the request message for the on-demand system information that UE is sent, if network determines to broadcast requested on-demand system information, according to LTE
Principle, system information update can only it is next modification the period boundary carry out, then base station it is next modification the period boundary
Place to must system information the scheduling information of the on-demand system information is updated, and broadcast.
Currently, base station can only update modified system information within next modification period, the period is changed at n-th
Interior, when UE has demand to on-demand system information SI2, the MSI that is sent from received base station is known in the scheduling information to SI2
Current base station does not broadcast SI2.UE sends the request message of SI2 to base station, and base station changes pair for receiving UE in the period at n-th
After the request message of SI2, meet base station certain criterion base stations determine broadcast the request SI2, then need change MSI in include
The on-demand system information scheduling information, indicate that the on-demand system information will be broadcasted.The period is changed at n-th in base station
Page notification is sent to all UE, to inform that all UE system informations will change, n is non-zero natural number.Then at (n+1)th
It changes at cycle boundary, base station is updated the necessary system information to change.For example, base station is by the tune of the SI2 in MSI
The instruction of degree information is updated to instruction broadcast SI2 without broadcast, and intrinsic necessity scheduling system information week in period is changed at (n+1)th
Phase broadcasts updated necessary system information.
It may include multiple necessary scheduling system information periods to be changed at one in the period, in each necessary system call week
In phase, base station can broadcast MSI.If base station determines to broadcast certain on-demand system information, but does not timely update what MSI included
The scheduling information of the on-demand system information, but MSI is just updated in next modification cycle boundary using the method for LTE and includes
The scheduling information of the on-demand system information.When needing the on-demand system information there is also other UE in current Modification Period,
Indicate that the on-demand system information is not being broadcasted in the necessary system information sent in current Modification Period due to base station, UE
It not will be considered that base station will broadcast the on-demand system information within any one on-demand scheduling system information period, therefore need to base
It stands and sends the request message of the on-demand system information.However, this can cause unnecessary signaling overheads, and increase system energy consumption
And system resource waste.
To solve the above problems, in embodiments of the present invention, when the request for the on-demand system information for receiving UE transmissions disappears
Breath, it is described on-demand in current Modification Period updates necessary system information at once when determining to broadcast the on-demand system information
The scheduling information of system information, instruction will broadcast the on-demand system information, and next in the current Modification Period must
Updated necessary system information must be broadcasted in the scheduling system information period.Pass through the institute in the necessary system information that timely updates
State the scheduling information of on-demand system information so that it is described on-demand that other need the UE of the on-demand system information that can know in time
System information will be broadcasted information, and UE individually need not send request message to base station.Base station need not also be sought to all UE
It calls through and knows to inform the change of UE system informations.UE need to only monitor the on-demand system in the dispatching cycle of the on-demand system information
Information window, you can receive the on-demand system information, so as to avoid unnecessary signaling overheads, and reduce power consumption and section
About system resource.
It is understandable to enable the above-mentioned purpose, feature and advantageous effect of the embodiment of the present invention to become apparent, with reference to attached
Figure is described in detail specific embodiments of the present invention.
Referring to Fig.1, a kind of flow chart of the dispatching method of on-demand system information in the embodiment of the present invention is given.Lead to below
Specific steps are crossed to be described in detail.
Step 11, it when the request message for the on-demand system information for receiving UE transmissions, and determines to broadcast the on-demand system
When information, the scheduling information of the on-demand system information in necessary system information is updated at once in current Modification Period.
In specific implementation, in 5G newly eats dishes without rice or wine (New Radio, NR), transmission MSI is periodically broadcasted in base station, is based on
On-demand SI are supplied to the specific UE by the demand of particular UE by dedicated signaling or broadcast mode.Base station is to On-
The scheduling information of demand SI can be carried by MSI.In an embodiment of the present invention, may include in MSI：SI types,
SI periods, efficient message and SI windows etc..It, can be from the On- in the MSI of base station broadcast when UE needs On-demand SI
Know in the scheduling information of demand SI and currently whether indicates that the On-demand SI are being broadcasted.
For example, in the scheduling information of On-demand SI in MSI, the On-demand SI are being indicated using 1
Broadcast indicates that the On-demand SI are not broadcasted using 0.
For another example, in the scheduling information of the On-demand SI in MSI, the On-demand SI are being indicated just using TRUE
It is broadcasting, is indicating that the On-demand SI are not broadcasted using FAULT.
In specific implementation, when indicating that On-demand SI are being broadcasted in MSI, the UE is from next on-demand system
The message scheduling period begins listening for the SI windows in the on-demand scheduling system information period, to receive the On-demand SI.
In specific implementation, when indicating that On-demand SI are not broadcasted in MSI, the UE is sent to the base station
The request message of On-demand SI.After the base station receives the request message for the On-demand SI that the UE is sent,
In specific implementation, when the base station determines to broadcast the On-demand SI, MSI is updated at once in current Modification Period
In the On-demand SI scheduling information, by the scheduling information of On-demand SI be updated to instruction will broadcast described in
On-demand SI。
In specific implementation, base station can be according to own load situation, information broadcast setting condition, UE to the on-demand system
The factors such as the conditions of demand for information of uniting, decide whether to broadcast the on-demand system information.In embodiments of the present invention, to base
It stands and determines that the factor that the broadcast on-demand system information is considered does not limit.
For example, base station can count in default first duration each UE of cell to the demand feelings of the On-demand SI
Condition decides whether broadcast On-demand SI according to UE to the conditions of demand of the On-demand SI.In the present invention one
In embodiment, the quantity of the request message of the received On-demand SI is more than default the in default first duration
It when one threshold value, determines to broadcast the On-demand SI, wherein first duration is less than the necessary scheduling system information week
Phase.
Using aforesaid way, On-demand SI are exported using broadcast mode, and no longer individually use dedicated signaling by On-
Demand SI are respectively supplied to corresponding UE, can be with saving signaling expense.
Step 12, in next necessary scheduling system information period in the current Modification Period, broadcast is updated
It must system information.
In specific implementation, after being updated to the On-demand SI scheduling informations in MSI, in current Modification Period
Next necessary scheduling system information period in, broadcast updated necessary system information.
As shown in the above, it when the request message for the on-demand system information for receiving UE transmissions, determines to press described in broadcast
When needing system information, the scheduling letter of the on-demand system information in necessary system information is updated at once in current Modification Period
Breath, instruction will broadcast the on-demand system information, and next necessary scheduling system information week in the current Modification Period
In phase, updated necessary system information is broadcasted.Pass through the on-demand system information in the necessary system information that timely updates
Scheduling information so that other need the UE of the on-demand system information that can know that the on-demand system information will be wide in time
It broadcasts, and need not individually send the request message of the on-demand system information to base station.It base station also need not triggering changing system information
Notice need not carry out page notification to inform the change of UE system informations to all UE.UE need to only monitor the on-demand system
System information window in the dispatching cycle of information, you can the on-demand system information is received, it is unnecessary so as to avoid
Signaling overheads, and reduce power consumption and save system resource.
The embodiment of the present invention is better understood from and realized for ease of those skilled in the art, with reference to specific example to this
The dispatching method for the on-demand system information that inventive embodiments provide illustrates.
With reference to Fig. 2, a kind of scheduling process schematic diagram of on-demand system information in the embodiment of the present invention is given.
In specific implementation, it may include multiple T1 MSI dispatching cycles and the tune of on-demand system information to change in cycle T 3
Spend cycle T 2.In an embodiment of the present invention, modification cycle T 3 includes 6 MSI T1 dispatching cycle, 3 on-demand system information tune
Spend cycle T 2.It is understood that the number of included MSI T1 dispatching cycle may be that other take in modification cycle T 3
Value, the number of included on-demand scheduling system information cycle T 2 can be other values.Change the MSI tune included by cycle T 3
The number of cycle T 1 and the specific value of number of on-demand scheduling system information cycle T 2 are spent, is not limited herein.
For example, when UE needs on-demand system information SIx, know that current base station is not wide in the MSI broadcasted from base station
SIx is broadcast, the request message (Request) of SIx can be sent to base station.In a certain period of time base station receive UE1,
UE2 ..., UEm send SIx request message, m be non-zero natural number.Due to needing the UE quantity of SIx more, in order to save
Resource, base station determine broadcast SIx at moment t1, and update the scheduling information of the SIx in MSI at once, and instruction will broadcast SIx, and
It broadcasts updated MSI in next MSI dispatching cycles, and SIx is broadcasted within SI dispatching cycles.UEm+1 ..., UEn it is right at this time
SIx has demand, can receive updated MSI in MSI dispatching cycles, confirms that SIx will be broadcasted, and no longer needs to send to base station
SIx request messages, n ＞ m are natural number.UE1, UE2 ..., UEm ..., UEn can monitor SI windows to receive SIx.Example
Such as, a length of when the monitoring of one of SI windows：Moment A to moment B.
In specific implementation, due to the influence of the factors such as channel circumstance variation, interference, base station possibly can not receive UE hairs
The request message of the On-demand SI sent, therefore base station will not transmit On-demand SI to the UE.However, UE is being distributed
After the request message of On-demand SI, one or more SI scheduling are begun listening for from next On-demand SI dispatching cycles
The SI windows in period go to receive On-demand SI.If UE does not receive On-demand SI, can ceaselessly be monitored always,
This, which not only results in UE, can not receive On-demand SI, and it is larger to also result in UE power consumptions.
To solve the above problems, in an embodiment of the present invention, can also include in the MSI that base station is sent：On-
The default monitoring duration of demand SI indicates information.The default monitoring duration instruction information of the On-demand SI is for referring to
Show that the UE monitors the duration in the on-demand scheduling system information period.The default monitoring duration can be that UE needs to monitor
M times of On-demand SI dispatching cycle, namely instruction need to monitor M On-demand SI dispatching cycle, and M is non-zero nature
Number.In specific implementation, may include a SI window in the On-demand SI dispatching cycles, it can be by monitoring On-
SI windows in demand SI dispatching cycle receive On-demand SI.
In an embodiment of the present invention, the default monitoring duration of On-demand SI sends asking for On-demand SI with UE
After seeking message, start to monitor the SI windows in next On-demand SI dispatching cycles, until monitoring M On-demand
SI windows in SI dispatching cycles.It can be configured with time set, such as timer in UE, default duration of monitoring can be counted
When.After timer unlatching, UE can know when to need to begin listening for the SI windows of the dispatching cycle of on-demand system information, and supervise
Listen M SI window.For example, a length of when preset monitoring is 10 times of the on-demand scheduling system information period, then UE will monitor 10
The SI windows in a on-demand scheduling system information period.
In specific implementation, the base station can be all On-demand SI one public timer of configuration, namely
The default monitoring duration all same of all On-demand SI；Or each On-demand SI configurations individually timing
Device that is to say the default monitoring duration of each On-demand SI, may be the same or different according to actual needs.
In specific implementation, the On-demand is not received in the default monitoring duration of On-demand SI as UE
SI, and it is described it is default monitor MSI received in duration and indicate that On-demand SI are not broadcasted in base station when, stop supervising
Listen the SI windows of the On-demand SI dispatching cycles.UE can send On-demand to base station again according to actual needs
The request message of SI.
Using the above scheme, must system information include the on-demand system information default monitoring duration indicate letter
Breath, after reaching default the monitorings duration, UE stops monitoring to the on-demand system information, so as to avoid UE because of
The on-demand system information of base station transmission is not received without stopping monitoring problem, can reduce power consumption.
With reference to Fig. 3, the scheduling process schematic diagram of another system information on demand in the embodiment of the present invention is given.Wherein,
T1 refers to the dispatching cycle of MSI, and T2 refers to SI dispatching cycles.UE needs on-demand system information SIx, in received base station broadcast
The scheduling information instruction current base station of SIx in MSI is not in broadcast SIx.UE disappears at the t3 moment to the request of base station transmission SIx
Breath.UE begins listening for the SI windows in SIx dispatching cycles, to receive the SIx after sending the request message of SIx to base station.
In an embodiment of the present invention, 2 times of a length of SIx dispatching cycles when the default monitoring, that is, monitoring 2 is needed
A SIx dispatching cycles.It is corresponding there are one SI windows within each SIx dispatching cycles, by monitor the SI windows in SIx dispatching cycles come
Receive the SIx.It is understood that it is described it is default monitor duration may be 5 times, 8 times of the SIx dispatching cycles or
Other multiples.
However, due to the influence of various factors, base station does not receive the request message for the SIx that the UE is sent, therefore
The scheduling information of the SIx in MSI is not updated, does not provide SIx to the UE yet.UE can also be under in default monitoring duration T4
One MSI begins listening for one or many MSI dispatching cycles dispatching cycle, to confirm that the scheduling information of the SIx in MSI is
It is no to be changed.After UE is in the default SI windows monitored in monitoring 2 SIx dispatching cycles in duration T4, SIx is not received,
And indicate that SIx is unscheduled namely base station in the default scheduling information for monitoring the SIx in MSI received in duration T4
It currently without broadcast SIx, then can cease listening for, and send the request message of SIx to the base station again at the t4 moment.
In specific implementation, it when On-demand SI are broadcasted in base station according to UE demands, will be unable to receive other UE pairs
The request message of On-demand SI.Under current state, base station will be unable to know demands of the follow-up UE to On-demand SI.
If currently without UE demand On-demand SI, and base station is also in periodically broadcast On-demand SI, it will bringing need not
The signaling overheads and power consumption wanted.
To solve the above problems, in specific implementation, base station can according to itself loading condition, to the broadcast of information when
Between, the broadcast of the number of broadcast times of information, information terminate the factors such as setting condition, to decide whether to terminate to broadcast the on-demand system
System information.For example, when the number of base station broadcast On-demand SI reaches default second threshold, can terminate to the On-
The broadcast of demand SI.It for another example, can be with after the duration of system information reaches default second duration on demand described in the base station broadcast
Terminate the broadcast to the On-demand SI.In embodiments of the present invention, base station is determined to terminate to broadcast the on-demand system
The factor that system information is considered does not limit.
In specific implementation, when the base station determines to terminate to broadcast the on-demand system information, in current Modification Period
The scheduling information for inside updating the on-demand system information in the necessary system information at once will be terminated described in broadcast with instruction
On-demand system information.In next necessary scheduling system information period in the current Modification Period, broadcast is updated must
It must system information.
Using the above scheme, when terminating to broadcast a certain on-demand system information, immediately by the institute in the necessary system information
The scheduling information for stating on-demand system information is updated to instruction end broadcast, and is broadcasted within next necessary scheduling system information period
Updated necessary system information, to need the UE of the On-demand SI that can know base station to On- in time in cell
The dispatch situation of demand SI so that UE can send the request of On-demand SI to base station in time according to the demand of itself
Message avoids not receiving On-demand SI for a long time to the UE that On-demand SI have demand.
