Description

Method, device, apparatus and storage medium for broadcasting on-demand system information

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for broadcasting on-demand system information, and a storage medium.

Background

5G(the 5 ^th generation, fifth generation mobile communication) system, system information is divided into 3 types: MSI (Minimum System Information ), RMSI (Remaining Minimum System Information, minimum system information remaining), and other system information OSI (on-demand System Information). MSI and RMSI are collectively referred to as minimum system information, which is always periodically broadcast, such as MIB (Master Information Block ) and SIB1 (System Information Block Type, system information block), which are the most basic information. Other system information includes all system information which is not broadcast in the minimum system information, and is optional broadcast information, and the system information is not sent periodically and can be sent in an on demand (on demand) broadcast mode requested by the terminal equipment.

The system information adopts an on-demand broadcasting mode, so that the energy consumption and the resource consumption of network side equipment caused by periodical broadcasting of unnecessary system information can be saved. Currently, after receiving an SI (System Information ) request on demand from a UE, the network side device either broadcasts the SI periodically all the time or turns off only by broadcasting several times. The SI-on-demand mode is broadcast periodically all the time, and SI resources cannot be saved, contrary to the original purpose of OSI design; the manner of closing only a few times of broadcasting can cause the problems of frequent change of SIB1, increase of air interface signaling overhead, unnecessary broadcasting update of other online UE, and the like, and the two modes cannot effectively and accurately broadcast the on-demand system information.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Fig. 1 is a flow chart of a broadcasting method of on-demand system information according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:

step 100, configuring an initial broadcast time for each on-demand system information;

the on-demand system information starts with SIB2 until the last SIB, the protocol may be extended later, so it is assumed here that there are a total of NumSIB on-demand SIBs:

configuring an initial broadcast time for each on-demand system information:

[IniStartTimeSIB2,IniEndTimeSIB2]、

[IniStartTimeSIB3,IniEndTimeSIB3]、

…

[IniStartTimeNumSIB,IniEndTimeNumSIB]。

in a specific embodiment, the initial broadcast time proposal is configured to be busy in that the default on-demand system information (hereinafter, simply referred to as on-demand SIB) is periodically broadcast in this period, considering that the more demand for on-demand system information is also when there are more users. The initial broadcast time may also be derived from historical statistics, such as the number of SIB requests on demand.

Step 101, counting the request times of each on-demand system information and the number of Radio Resource Control (RRC) connection state users in a target counting period (SP);

in one embodiment, the time for starting counting the number of requests of each on-demand system information and the number of RRC (Radio Resource Control ) connected users is the on time of the on-demand system information broadcasting function switch.

The subsequent steps of the broadcasting method of the on-demand system information provided by the embodiment of the application are all based on the period statistics, so that the statistics period SP (Static Period) is introduced, the data of each period is analyzed to determine whether a certain on-demand SIB is started in the next period, and so on.

The purpose of the statistics-based period SP is to enable modifications as soon as possible when there is a change in the SIB on demand.

Specifically, the number of requests NumSIBX and the number of radio resource control RRC connected state users NumRRCCon of each on-demand system information SIB X within a certain statistics period SP are counted.

Step 102, determining the broadcasting state and the scheduling period of the target on-demand system information according to the request times of the target on-demand system information in the target SP and/or the number of Radio Resource Control (RRC) connection state users.

It should be noted that, because SIB 2-SIB 5 are information for cell reselection of idle state UEs, the network side cannot count the number of idle state UEs, so the number of connected state UEs is adopted to replace the number of idle state UEs (User Equipment). Other on-demand SIBs also replace the number of idle state UEs with the number of connected state UEs to determine an indicator of the need for the SIB.

And analyzing whether the target on-demand system information is broadcasted or not according to the request times of the target on-demand system information in the target SP and/or the number of Radio Resource Control (RRC) connection state users.

It can be appreciated that if, in the target SP, the number of requests for the target on-demand system information and the number of radio resource control RRC connected users do not reach the broadcast threshold of the on-demand system information, it is determined that the target on-demand system information is not broadcast in the next period.

If the request times of the target on-demand system information and/or the number of Radio Resource Control (RRC) connection state users in the target SP reach the broadcasting threshold of the on-demand system information, determining that the target on-demand system information needs to be broadcasted in the next period.

Here, the next period is the next SP period of the target SP.

If it is determined that the target on-demand system information needs to be broadcasted in the next period, further calculating a scheduling period of the target on-demand system information according to the request times of the target on-demand system information in the target SP or the number of Radio Resource Control (RRC) connection state users.

In one embodiment, the target on-demand system information is deleted if it is determined that the target on-demand system information is not broadcast in the next period.

The above step 102 is performed for all on-demand system information.

Step 103, adjusting the broadcasting state and the scheduling period of the target on-demand system information in the system information block SIB1 based on the broadcasting state and the scheduling period of the target on-demand system information.

Finally, based on the broadcasting state and the scheduling period of the target on-demand system information, the broadcasting state and the scheduling period of the target on-demand system information in the system information block SIB1 are adjusted, so that each on-demand system information is broadcasted according to the broadcasting state and the scheduling period of the target on-demand system information and the broadcasting time of each on-demand system information.

According to the broadcast method of the on-demand system information, the on-demand SIB broadcast is adjusted according to the real-time statistic value, and the on-demand system information can be broadcast efficiently and accurately.

Based on the foregoing embodiments, in the on-demand system information broadcasting method provided in another embodiment of the present application, the determining, according to the number of requests and/or the number of radio resource control RRC connected users of the target on-demand system information in the target SP, a broadcasting state and a scheduling period of the target on-demand system information includes:

It should be noted that, the first preset time period is not busy here. Because the on-demand SIB is always broadcast when busy, the number of requests for SIB X is not counted, i.e., the number of requests for SIB X is 0.

And if the target SP is not busy and the request times of the target on-demand system information in the target SP are greater than zero, determining to broadcast the target on-demand system information. It will be appreciated that the UE has a need to meet.

And determining the scheduling period of the target on-demand system information according to the request times of the target on-demand system information in the target SP. In the implementation, whether the target on-demand system information is currently broadcast can be judged first, if the target on-demand system information is currently broadcast, the scheduling period of the target on-demand system information is maintained, and if the target on-demand system information is not currently broadcast, the scheduling period of the target on-demand system information is calculated according to the request times of the target on-demand system information in the target SP.

Specifically, in one SP period, x=2, …, numSIB, each SIB X needs to make a judgment:

judging whether the request times NumSIBX of the SIB X meet the following conditions:

NumSIBX >0 formula 1

If equation 1 is satisfied, it is determined that the SIB X is to be broadcast later.

Then, according to the number of requests of SIB X in the SP, table look-up table 1 can obtain the scheduling period of SIBX. The SIB request number threshold and SIB scheduling period in table 1 may be determined according to an application scenario and an empirical value, or may be calibrated to an appropriate value according to sample data.

Table 1 SIB request times threshold and scheduling period

SIB request times low threshold	SIB request times high threshold	SIB scheduling period
			SIB request times threshold 1	SIB request times threshold 2	8 radio frames
SIB request times threshold 3	SIB request times threshold 4	16 radio frames
			SIB request times threshold 5	SIB request times threshold 6	32 radio frames
SIB request times threshold 7	SIB request times threshold 8	64 radio frames
			SIB request times threshold 9	SIB request times threshold 10	128 radio frames
SIB request times threshold 11	SIB request times threshold 12	256 radio frames
			SIB request times threshold 13	SIB request times threshold 14	512 radio frames

According to the method for broadcasting the on-demand system information, which is provided by the embodiment of the application, the on-demand system information broadcasting is adjusted according to the request times of the on-demand system information, so that the on-demand system information can be efficiently and accurately broadcast.

Specifically, if the number of requests NumSIBX of SIB X in the SP is 0, it is further determined whether the RRC connection state user number NumRRCCon of the target on-demand system information in the target SP satisfies:

NumRRCCon > ThesNumRRCConUE equation 2

Wherein, thesnumrrcconuue is RRC connected user number threshold.

If equation 2 is satisfied, it is determined that the SIB X is later broadcast.

For SIB X currently being broadcast, its scheduling period is maintained as it is in order to avoid frequent modification of SIB1 during busy hours. The scheduling period of SIB X is determined for SIB X table 2 that is not currently broadcast. Also, the RRC connected user number threshold and SIB scheduling period in table 2 may be determined according to an application scenario and an empirical value, or may be calibrated to an appropriate value according to sample data.

Table 2RRC connected user number threshold and scheduling period

RRC connection state user quantity low threshold	RRC connected user number high threshold	SIB scheduling period
			RRC connected user quantity threshold 1	RRC connected user number threshold 2	8 radio frames
RRC connected user number threshold 3	RRC connected user number threshold 4	16 radio frames
			RRC connected user quantity threshold 5	RRC connected user number threshold 6	32 radio frames
RRC connected user number threshold 7	RRC connected state user number threshold 8	64 radio frames
			RRC connected user number threshold 9	RRC connected user number threshold 10	128 radio frames
RRC connected user number threshold 11	RRC connected user number threshold 12	256 radio frames
			RRC connected user number threshold 13	RRC connected user number threshold 14	512 radio frames

If the number of requests NumSIBX of SIB X within the SP is 0 and the RRC connected user number NumRRCCon < = thesnumrrccon ue, it is determined that SIB X is not broadcasted later.

According to the broadcast method of the on-demand system information, the on-demand SIB broadcast is adjusted according to the request times of the on-demand SIB counted in real time and the RRC connection state user number, and the on-demand system information can be broadcast efficiently and accurately.

Optionally, according to an embodiment of the present application, the method for broadcasting on-demand system information determines a broadcasting status and a scheduling period of the on-demand system information according to a request number of the on-demand system information and/or a radio resource control RRC connection state user number in the target SP, including:

It should be noted that the second preset time period is busy. When busy, because the on-demand SIB is always broadcast, the number of requests of SIB X is not counted, that is, the number of requests of SIB X is all 0, so that the broadcast state and the scheduling period of the on-demand system information of the target are determined according to the number of radio resource control RRC connection state users of the on-demand system information in the target SP.

It should be noted that, the busy hours and the non-busy hours in the embodiment of the present application may be time periods obtained based on statistics of historical data, or preset time periods.

Specifically, judging whether the RRC connection state user number NumRRCCon of the target on-demand system information in the target SP satisfies:

NumRRCCon > ThesNumRRCConUE equation 2

Wherein, thesnumrrcconuue is RRC connected user number threshold.

If equation 2 is satisfied, it is determined that the SIB X is later broadcast.

For SIB X currently being broadcast, its scheduling period is maintained as it is in order to avoid frequent modification of SIB1 during busy hours. The scheduling period of SIB X is determined for SIB X table 2 that is not currently broadcast.

Table 2 is given in the previous embodiment and will not be described here again.

According to the broadcast method of the on-demand system information, the on-demand SIB broadcast is adjusted according to the RRC connection state user number counted in real time, and the on-demand system information can be broadcast efficiently and accurately.

Based on the foregoing embodiment, according to a broadcasting method of on-demand system information of one embodiment of the present application, the broadcasting state and the scheduling period of the target on-demand system information in the system information block SIB1 are adjusted based on the broadcasting state and the scheduling period of the target on-demand system information, including:

Specifically, it is determined whether the SIB X goes through the modification procedure when the next Modification Period arrives.

Judging whether the SIB X obtained in the step 102 is broadcast or not, and judging whether the scheduling period is consistent with the current broadcast state and the scheduling period of the SIB X; if the SIB X broadcast is inconsistent, the modification flow of the SIB X is carried out when the latest and next MP (Modification Period, correction period) arrives, so that the rapid adjustment of the SIB X broadcast is realized.

Considering the change broadcast, at least two Modification Period are needed, and when the SIB X needs to be changed at a given time Modification Period, the latest SIB X broadcast and scheduling period are subject to, and the previous SIB X broadcast and scheduling period is discarded.

Optionally, according to the broadcasting method of the on-demand system information of one embodiment of the present application, the correction period MP is N times the statistical period SP, and N is greater than or equal to 1.

Fig. 2 is a schematic diagram of the relationship between the statistical period SP and the correction period MP. In one embodiment, for simplicity of implementation, it is recommended that SP be equal to MP, with SP start slightly earlier than MP.

The broadcast method of the on-demand system information provided by the embodiment of the application carries out adjustment of on-demand SIB broadcast according to the real-time statistic value, can efficiently and accurately broadcast the on-demand system information, reduces frequent change of broadcast, reduces unnecessary broadcast update of other on-line UE, thereby reducing influence on normal service, realizing reduction of air interface signaling overhead when in high load, avoiding frequent transmission of on-demand broadcast request by UE, avoiding or reducing frequency transmission of on-demand SIB under no load or low load condition, and saving a large amount of resources and energy.

In order to further explain the broadcasting method of the on-demand system information provided in the above embodiments, in particular, how to determine whether to change the broadcasting state and the scheduling period of a certain SIB X, the present application is exemplified by assuming that the busy hour is 9 to 11 a.m. and the other time is not busy, and assuming that the statistical period SP is 32 radio frames, and MP is equal to SP. Assume that the RRC connected state user number threshold thresnumrrccone ue is 10. Only on-demand SIBs within one statistical period SP are illustrated here, distinguishing busy and non-busy times, other period handling methods are similar and will not be described in detail here. Referring to fig. 3, the broadcasting method of on-demand system information provided by the embodiment of the present application includes the following steps:

step 1: an initial broadcast time is configured for each on-demand SIB based on busy hours.

Initial broadcast time of SIB 2: [09:00,11:00

Initial broadcast time of SIB 3: [09:00,11:00

…

Initial broadcast time of SIB NumSIB: [09:00,11:00].

Note: the busy hour of each on-demand broadcast may be different and may be actually configured according to the requirements of the respective SIB X. Here the same for simple configuration.

Step 2: and periodically counting the request times NumSIBX of each SIB on demand and the number of RRC connection state users NumRRCCon.

Suppose that the number of RRC connected users NumRRCCon is 100 within 32 radio frames during a certain statistics period in busy hours. Since these on-demand SIBs are always broadcast during busy hours, the number of requests for SIB X will not be counted, i.e., the number of requests for SIB X is 0.

Suppose that the number of requests NumSIBX NumRRCCon for each on-demand SIB in 32 radio frames in a certain statistical period of non-busy hours is as follows, in which the RRC-connected user number NumRRCCon is 8.

Table 3 request times for SIB X

SIB 2 request times	10
		SIB 3 request times	20
SIB 4 request times	8
		SIB 5 request times	2

Busy and non-busy times do not exist simultaneously. This is for illustration only.

Step 3: and analyzing the statistical data of each SP period, including the number of requests NumSIBX and the number of RRC connection state users NumRRCCon of each SIB on demand, so as to obtain whether a certain SIB needs broadcasting and scheduling period.

The SIB request times threshold and the scheduling period are assumed as shown in table 4 below. Assume that the RRC connected state user number threshold and the scheduling period are shown in table 5 below.

Table 4SIB request times threshold and scheduling period example

SIB request times low threshold	SIB request times high threshold	SIB scheduling period
			320	65535	8 radio frames
160	320	16 radio frames
			80	160	32 radio frames
40	80	64 radio frames
			20	40	128 radio frames
10	20	256 radio frames
			1	10	512 radio frames

Table 5RRC connected user number threshold and scheduling cycle example

RRC connection state user quantity low threshold	RRC connected user number high threshold	SIB scheduling period
			640	65535	8 radio frames
320	640	16 radio frames
			160	320	32 radio frames
80	160	64 radio frames
			40	80	128 radio frames
20	40	256 radio frames
			10	20	512 radio frames

According to the statistical result of the step 2:

busy hour:

1) The RRC connected user number NumRRCCon is 100, which is greater than the on-demand broadcast threshold thesnumrrccon ue (with a value of 10), so each on-demand system message needs to be continuously broadcast in the next period.

2) Looking up table 5, the number of RRC connection state user NumRRCCon is between 80 and 160, and each SIB scheduling period can be obtained to be 64 radio frames. The specific description is as follows: the table 5 need not be looked up for the SIB scheduling period being broadcast to remain the same.

For the non-busy hours:

1) SIB 2 requests a number of times of 10, greater than 0, so SIB 2 needs to be broadcast in the next period. Look-up table 4 is between [10, 20), so its scheduling period is 256 radio frames.

SIB 3 requests 20 times, greater than 0, so SIB 3 needs to be broadcast in the next period. Look-up table 4 is between [20, 40 ], so its scheduling period is 128 radio frames.

SIB 4 requests a number of times of 8, greater than 0, so SIB 4 needs to be broadcast in the next period. Look-up table 4 is between [1, 10), so its scheduling period is 512 radio frames.

SIB 5 requests a number of times of 2, greater than 0, so SIB 5 needs to be broadcast in the next period. Look-up table 4 is between [1, 10), so its scheduling period is 512 radio frames.

2) And if the number of requests of other SIB, SIB 6 to SIB 9 (the current protocol only reaches SIB 9) is 0, determining whether to broadcast and schedule according to the number of RRC connected UE.

The number of RRC connection state user NumRRCCon is 8 and is smaller than the on-demand broadcasting threshold 10 in the non-busy time, so that SIB 6-SIB 9 do not need to be broadcasted.

Step 4: it is determined whether the SIB X goes through the modification procedure at the next Modification Period arrival.

Assume that the current (applicable busy and non-busy) SIB 2-SIB 4 state in SIB 1 is broadading and SIB 5 is not currently broadcast as notbroadading. And the scheduling period of SIB 2 is 256 wireless frames, and the scheduling periods of SIB 3-SIB 4 are 512 wireless frames.

According to the result of busy hour: SIB 2-SIB 4 need not modify the state and scheduling period in SIB 1, but need to modify the scheduling state of SIB 5 to broadcasting and the scheduling period to 64 radio frames. It is thus determined that SIB 5 is going to go through the modification procedure when the next Modification Period arrives.

According to the result of the non-busy hour:

SIB 2 does not need to modify the state in SIB 1, and does not need to modify the scheduling period.

SIB 3 does not need to modify the state in SIB 1, but needs to modify the scheduling period, from 512 radio frames to 128 radio frames.

SIB 4 does not need to modify the state in SIB 1 and does not need to modify the scheduling period.

SIB 5 needs to modify the state in SIB 1, from non-tbroadcasting to broadcasting, with a scheduling period of 512 radio frames.
