Description

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

Technical Field

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

Background

5G(the 5^thgeneration, fifth generation mobile communication) system, system information is divided into 3 types: MSI (Minimum System Information), RMSI (Remaining Minimum System Information), and other System Information OSI (on-demand System Information). The MSI and the RMSI are jointly called minimum system information which is always periodical and wideThe broadcast, such as MIB (Master Information Block) and SIB1(System Information Block Type 1), are the most basic Information. The other system information includes all the system information which is not broadcasted in the minimum system information, and is optional broadcast information, and is not transmitted periodically, and can be transmitted in an on-demand (on demand) broadcast mode requested by the terminal device.

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

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

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

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

the on-demand system information may continue to expand from SIB2 until the last SIB, so it is assumed here that there are a total of NumSIB on-demand SIBs:

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

[IniStartTimeSIB2,IniEndTimeSIB2]、

[IniStartTimeSIB3,IniEndTimeSIB3]、

…

[IniStartTimeNumSIB,IniEndTimeNumSIB]。

in a specific embodiment, the default on-demand system information (hereinafter referred to as on-demand SIB) is broadcast periodically during the initial broadcast time when the configuration is busy, taking into account the increased need for on-demand system information 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 number of times of requests of each on-demand system information and the number of users of Radio Resource Control (RRC) connection state in a target counting period SP;

it should be noted that, in an embodiment, the time for starting counting the number of times of requesting each piece of on-demand system information and the number of users in a Radio Resource Control (RRC) connected state is the starting time of the on-demand system information broadcasting function switch.

The subsequent steps of the method for broadcasting the on-demand system information provided by the embodiment of the application are counted based on the period, so that a counting period SP (static period) is introduced, data of each period is analyzed to determine whether a next period starts a certain on-demand SIB, and so on.

The purpose of the SP is based on the statistical period is to modify the SIB as quickly as possible when there is a change in the SIB as required.

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

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

It should be noted that, since SIB2 to SIB5 are information for cell reselection by idle UEs, the network side cannot count the number of idle UEs, and therefore, the number of connected UEs is used instead of the number of idle UEs (User Equipment). Other on-demand SIBs also use the number of connected UEs instead of the number of idle UEs to determine an indicator of the SIB requirements.

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

It can be understood that, if in the target SP, both the number of times of requesting the target on-demand system information and the number of users in the RRC connected state 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.

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

It should be noted that, here, the next cycle is the next SP cycle of the target SP.

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

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 broadcast state and the scheduling period of the target on-demand system information in a system information block SIB1 based on the broadcast state and the scheduling period of the target on-demand system information.

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

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

It should be noted that, here, the first preset time period is not busy. Because the SIB is always broadcast on demand during busy hours, 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 on-demand system information in the target SP is not busy and the request frequency of the target on-demand system information is greater than zero, determining to broadcast the target on-demand system information. It can be appreciated that the UE has a need to do so.

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 a specific implementation, it may be determined whether the target on-demand system information is currently being broadcast, if the target on-demand system information is currently being broadcast, the scheduling period of the target on-demand system information is maintained, and if the target on-demand system information is not currently being broadcast, the scheduling period of the target on-demand system information is calculated according to the number of times of requests for the target on-demand system information in the target SP.

Specifically, in one SP period, X is 2, …, NumSIB, and each SIB X is to be determined:

judging whether the number NumSIBX of SIB X requests is satisfied:

NumSIBX >0 equation 1

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

Then, based on the number of requests of SIBX in the SP, looking up Table 1 can get 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 appropriate values according to sampling data.

Table 1 SIB number of requests threshold and scheduling period

SIB request number lower threshold	High threshold for SIB request times	SIB scheduling period
			Threshold of SIB request times 1	Threshold of SIB request times 2	8 radio frames
Threshold of number of SIB requests 3	Threshold of SIB request times 4	16 radio frames
			Threshold number of SIB requests 5	Threshold of SIB request times 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	Threshold number of SIB requests 12	256 radio frames
			SIB request times threshold 13	SIB request times threshold 14	512 radio frames

According to the broadcasting method of the on-demand system information, the on-demand system information broadcasting is adjusted according to the request times of the on-demand system information, and the on-demand system information can be efficiently and accurately broadcast.

Specifically, if the number of times numsbx of requests of SIB X in the SP is 0, it is further determined whether or not the RRC connected state user number NumRRCCon of the target on-demand system information in the target SP satisfies:

NumRRCCon > ThesNumRRCConUE equation 2

Wherein, the thernumrrccone ue is the threshold of the RRC connected user number.

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

For this SIB X currently being broadcast, its scheduling period remains the same in order to avoid frequent changes of the SIB1 during busy hours. The SIB X table lookup 2 determines the SIB X scheduling period for which the SIB X is not currently broadcast. Similarly, the RRC connected user number threshold and the SIB scheduling period in table 2 may be determined according to an application scenario and an empirical value, or may be calibrated to obtain a suitable value according to sampling data.

Table 2RRC connected user number threshold and scheduling period

RRC connected state user number low threshold	High threshold of RRC connected state user number	SIB scheduling period
			RRC connected user number 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
			RRCConnected user number threshold 5	RRC connected user number threshold 6	32 radio frames
RRC connected user number threshold 7	RRC connected user number threshold 8	64 radio frames
			Threshold for number of users in RRC connection state 9	RRC connected user number threshold 10	128 radio frames
RRC connected user number threshold 11	Threshold for number of users in RRC connection state 12	256 radio frames
			RRC connected user number threshold 13	Threshold for number of users in RRC connected state 14	512 radio frames

If the number of requests numsbx in the SP is 0 and the RRC connected user number NumRRCCon < (the snnumrrccone ue), it is determined that the SIB X is not broadcast later.

According to the method for broadcasting the on-demand system information, the on-demand SIB broadcasting is adjusted according to the number of times of requests of the on-demand SIB counted in real time and the number of users in an RRC (radio resource control) connection state, and the on-demand system information can be efficiently and accurately broadcasted.

Optionally, according to the method for broadcasting on-demand system information in an embodiment of the present application, the determining a broadcast state and a scheduling period of the target on-demand system information according to the number of times of requests of the target on-demand system information in the target SP and/or the number of users in a radio resource control RRC connected state includes:

It should be noted that the second preset time period is busy. In busy hour, because the on-demand SIB is always broadcast, the number of times of SIB X requests is not counted, i.e. the number of times of SIB X requests is 0, and therefore, the broadcast state and the scheduling period of the target on-demand system information are determined according to the number of RRC connected state users controlled by the radio resource of the target on-demand system information in the target SP.

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

Specifically, whether the number NumRRCCon of RRC connected state users of the target on-demand system information in the target SP satisfies:

NumRRCCon > ThesNumRRCConUE equation 2

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

For this SIB X currently being broadcast, its scheduling period remains the same in order to avoid frequent changes of the SIB1 during busy hours. The SIB X table lookup 2 determines the SIB X scheduling period for which the SIB X is not currently broadcast.

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

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

Based on the content of the foregoing embodiment, according to the method for broadcasting on-demand system information in one embodiment of the present application, the adjusting the broadcast state and the scheduling period of the target on-demand system information in the system information block SIB1 based on the broadcast state and the scheduling period of the target on-demand system information includes:

Specifically, it is determined whether the SIB X goes to modify the flow when the next Modification Period comes.

Judging whether the SIB X obtained in the step 102 is broadcasted and whether the scheduling period is consistent with the current broadcasting state and scheduling period of the SIB X; if not, the SIB X Modification process is performed when the latest MP (Modification Period) comes, so as to realize the rapid adjustment of SIB X broadcast.

Considering that the change broadcast needs at least two Modification Period, when the SIB X needs to be changed at a given Modification Period time, the latest SIB X broadcast and scheduling Period is taken as the standard, and the previous SIB X which is not yet changed is discarded.

Optionally, according to the method for broadcasting on-demand system information in an embodiment of the present application, the correction period MP is N times the statistical period SP, where N ≧ 1.

Fig. 2 is a schematic diagram of the relationship between the statistical period SP and the calibration period MP. In one embodiment, for simplicity of implementation, it is proposed that SP be equal to MP and SP start slightly before MP.

According to the broadcasting method of the on-demand system information, the on-demand SIB broadcasting is adjusted according to the real-time statistic value, the on-demand system information can be efficiently and accurately broadcasted, frequent change of broadcasting is reduced, unnecessary broadcast update of other on-line UE is reduced, influence on normal service is reduced, reduction of air interface signaling overhead is achieved under high load, the UE does not need to frequently send on-demand broadcasting requests, the on-demand SIB is not sent any more or at low frequency under the condition of no load or low load, and a large amount of resources and energy are saved.

To further illustrate the method for broadcasting the on-demand system information provided in the foregoing embodiments, and particularly how to determine whether to change the broadcast state and the scheduling period of a certain SIB X, the present application exemplifies that a busy hour is 9 to 11 am, and other times are not busy, a statistical period SP is 32 radio frames, and MP is equal to SP. Assume that the RRC connected user number threshold, thesnurrccion ue, is 10. The on-demand SIB in one statistical period SP is only illustrated here to distinguish busy time from non-busy time, and other period processing methods are similar and will not be described in detail here. Referring to fig. 3, a method for broadcasting on-demand system information provided by an 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 hour.

Initial broadcast time of SIB 2: [09: 00,11: 00], (iii),

Initial broadcast time of SIB 3: [09: 00,11: 00], (iii),

…

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

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

Step 2: and periodically counting the number NumSIBX of requests of each on-demand SIB and the number NumRRCCon of RRC connected state users.

Suppose the number of RRC connected state users NumRRCCon is 100 in 32 radio frames in a certain statistical period of busy hour. In busy hours, because the on-demand SIBs are always broadcast, the number of requests of SIB X is not counted, i.e. the number of requests of SIB X is 0.

The number of times NumSIBX NumRRCCon requests for each on-demand SIB in a certain statistical period 32 radio frames during non-busy hours is assumed as shown in the following table, and the number of RRC connected state users NumRRCCon in the period is 8.

TABLE 3 number of SIB X requests

Number of SIB2 requests	10
		Number of SIB3 requests	20
Number of SIB 4 requests	8
		Number of SIB5 requests	2

Busy hours and not busy hours do not exist simultaneously. This is for example only.

And step 3: the statistical data of each SP period, including the number of times NumSIBX of requests and the number NumRRCCon of RRC connected state users of each on-demand SIB, are analyzed to determine whether a certain SIB needs to be broadcasted and the scheduling period.

Assume that the SIB request times threshold and the scheduling period are shown in Table 4 below. It is assumed that the threshold of the number of users in RRC connected state and the scheduling period are shown in table 5 below.

Table 4SIB number threshold and scheduling period examples

SIB request number lower threshold	High threshold for SIB request times	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 5 example of user number threshold and scheduling period in RRC connected state

RRC connected state user number low threshold	High threshold of RRC connected state user number	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 number of RRC connected users NumRRCCon is 100, which is greater than the on-demand broadcast threshold, thernumrrccon ue (value is 10), so that each on-demand system message needs to be continuously broadcast in the next period.

2) Looking up the table 5, the number NumRRCCon of RRC connected users is between 80 and 160, and it can be obtained that each SIB scheduling period is 64 radio frames. Specifically, the following description is provided: table 5 need not be consulted for the SIB scheduling period being broadcast.

For non-busy hours:

1) the number of requests for SIB2 is 10, which is greater than 0, so SIB2 needs to be broadcast in the next period. Look-up table 4 is between [10, 20), so its scheduling period is 256 radio frames.

The number of requests for SIB3 is 20, which is greater than 0, so SIB3 needs to be broadcast in the next period. Table 4 is between [20, 40), so its scheduling period is 128 radio frames.

The number of requests for SIB 4 is 8, which is greater than 0, so SIB 4 needs to be broadcast in the next period. Table 4 is between [1, 10), so the scheduling period is 512 radio frames.

The number of requests for SIB5 is 2, which is greater than 0, so SIB5 needs to be broadcast in the next period. Table 4 is between [1, 10), so the scheduling period is 512 radio frames.

2) If the number of requests of other SIBs, SIB 6 to SIB 9 (until SIB 9 is currently used in the protocol) is 0, it is necessary to determine whether to broadcast and schedule a period according to the number of UEs in the RRC connected state.

The number of the RRC connection state users NumRRCCon is 8 when not busy, and is smaller than the on-demand broadcast threshold 10, so SIB 6-SIB 9 do not need to be broadcast.

And 4, step 4: and determining whether the SIB X goes to change the flow when the next Modification Period comes.

Assume that the current (applicable busy hour and non busy hour) states of SIB 2-SIB 4 in SIB1 are broadcasting, and SIB5 is not broadcasting. The SIB2 scheduling period is 256 radio frames, and the SIB 3-SIB 4 scheduling periods are 512 radio frames.

According to the result of busy hour: SIB 2-SIB 4 need not modify the state and scheduling period in SIB1, but need to modify the scheduling state of SIB5 to broadcasting and the scheduling period to 64 radio frames. Therefore, it is determined that SIB5 will change the flow when the next Modification Period comes.

According to the result of non busy:

SIB2 does not need to modify the state in SIB1, not the scheduling period.

SIB3 does not need to modify the state in SIB1, 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 SIB1, not the scheduling period.

The SIB5 needs to modify the state in SIB1 from notBaccasting to broadcasting, with a scheduling period of 512 radio frames.
