Description

System information updating method and device, electronic equipment and storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for updating system information, an electronic device, and a storage medium.
Background
In a 5G New Radio (NR) system, some System Information Blocks (SIBs) are valid not only in a current cell but also in an Area (Area), and such system information is called Area specific (Area specific) system information. The block region is composed of one or more cells, and each cell constituting the block region indicates the ID of the region to which it belongs in its SIB 1. In addition, each SIB (except SIB 1) has a version called a tag value (value tag). When the SIB content is changed, the cell needs to update the tag value of the SIB in SIB1, i.e., add 1, and if the tag value after adding 1 exceeds the maximum standard value, the tag value is set to 0.
When User Equipment (UE) acquires an SIB with a specific area from a camped cell, the SIB content and its version (tag value) are stored in the UE. If during operation of the 5G network the system information contains a change, and a region-specific SIB is changed, each cell belonging to the region indicates that the SIB has changed, i.e. the value of the label in SIB1 corresponding to the SIB has been changed (i.e. increased by 1). At this time, after receiving the notification from the network, the UE in each cell in the area reads the SIB1 in the current cell, and if the tag value of a certain SIB broadcasted by the cell is found to be different from the tag value stored by itself, it determines that the SIB information content has changed, and then reads the updated SIB, and replaces the previously stored version.
However, in the above scheme for updating the SIB, when a specific SIB in a region is changed, a plurality of cells constituting the region may be deployed in a plurality of different base stations, and the operation steps of the base stations performing SIB modification may not be synchronized, that is, there may be a certain time difference. For example, at some point cell a (under base station a) has updated the SIB first, while cell B (under base station B) has not updated the SIB, then the UE under cell a has acquired the latest version of the SIB and saved it locally. And then, the UE moves to the cell b, and if the SIB version of the current cell b is different from the version stored by the UE, the UE acquires the SIB again and stores the SIB. After a while, the cell b also updates the SIB (the content of which is the same as that of the cell a), and informs the UE through paging, and if the UE finds that the updated SIB has a different version from the stored version, the SIB is re-acquired from the cell b again and stored. However, the SIB content acquired by the UE from the cell b last is completely the same as the SIB content acquired in the cell a before, which means that the UE performs two meaningless SIB acquisition operations, increasing power consumption of the UE.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
As shown in fig. 1, which is a flowchart illustrating steps of a system information updating method according to an embodiment of the present invention, the method includes the following steps:
step 101: when User Equipment (UE) acquires the system information SIB with specific areas from the current resident cell and stores the SIB to the local, starting a pre-configured SIB timer.
In this step, specifically, in the 5G NR system, when the UE acquires the SIB with the area specific from the current cell and stores the SIB locally, the SIB timer may be started to time the SIB is stored by the UE.
Specifically, the SIB timer is configured for the UE in advance for the system, and is a holding timer of the SIB specified in the area. For example, the system may configure the SIB timer for the UE via the SIB2 message. Of course, it should be noted that the specific way in which the system configures the SIB timer for the UE is not specifically limited herein.
Step 102: when detecting that the cell where the UE resides is changed and the changed resident cell belongs to the intra-area cell, acquiring the label value of the SIB specific to the area of the changed resident cell and acquiring the current state of the SIB timer.
In this step, specifically, when the UE detects that the cell where the UE resides is changed and the changed cell where the UE resides belongs to the intra-area cell, the current state of the SIB timer may be acquired, and the tag value of the SIB specific to the area of the changed cell where the UE resides may be acquired.
In particular, the current state of the SIB timer may include a time-out state and a non-time-out state.
In addition, specifically, all SIBs in a region are valid SIBs, and then a cell in the region is an intra-region cell.
Specifically, when acquiring the tag value of the region-specific SIB for the changed camped cell, the UE may read the SIB1 broadcasted by the changed camped cell and acquire the tag value of the region-specific SIB for the changed camped cell from the read SIB 1.
In addition, it should be noted that the camping cell after the UE is changed may be a camping cell corresponding to the SIB stored in the UE locally, that is, the UE may return to the current camping cell after being changed twice, that is, the number of times the UE changes the camping cell is not specifically limited herein.
In this way, by acquiring the tag value of the SIB specified by the changed camping cell and the current state of the SIB timer, instead of directly acquiring the SIB specified by the changed camping cell after changing the camping cell, the UE is prevented from acquiring an invalid SIB when the SIB specified by the changed camping cell is an SIB that is not updated in time.
Step 103: and judging whether to update the SIB stored in the local by the UE according to the changed label value of the SIB residing in the cell and the current state of the SIB timer.
In this step, specifically, after the UE acquires the modified SIB with the specific region of the camping cell, it may be determined whether to update the SIB stored in the local area of the UE according to the tag value of the modified SIB with the specific region of the camping cell and the current state of the SIB timer.
Therefore, whether the SIB stored in the local UE is updated or not is judged according to the changed label value of the SIB specific to the region of the resident cell and the current state of the SIB timer, so that the situation that the SIB stored in the local UE is updated to the invalid SIB by the UE when the changed SIB specific to the region of the resident cell is not updated in time is avoided, the invalid workload of the UE is reduced, and the power consumption of the UE is reduced.
In the embodiment, the UE acquires the SIB with the specific region from the current cell and stores the SIB in the local region, starts the SIB timer with the preset configuration, acquires the tag value of the SIB with the specific region of the modified cell and the current state of the SIB timer when it is detected that the cell where the UE resides is changed and the modified cell belongs to the intra-region cell, and finally determines whether to update the SIB stored in the local region according to the current state of the SIB timer and the tag value of the SIB of the modified cell, so as to determine whether to update the SIB stored in the local region according to the current state of the SIB timer and the tag value of the SIB of the modified cell, thereby avoiding the problem that in the prior art, when the modified cell where the SIB of the cell resides is different from the SIB stored in the local region, the UE acquires the SIB of the modified cell in real time to update, therefore, the problem that the UE is updated to the invalid SIB due to the fact that the base station executes SIB updating asynchronization is avoided, invalid workload of the UE is reduced, power consumption of the UE is reduced, and updating efficiency of the SIB of the UE is improved.
Further, when determining whether to update the SIB stored in the local by the UE according to the changed tag value of the SIB of the camping cell and the current state of the SIB timer, it may first detect whether the changed tag value of the SIB of the camping cell is the same as the tag value of the SIB stored in the local by the UE, to obtain a first detection result; and then judging whether to update the SIB stored in the local by the UE according to the first detection result and the current state of the SIB timer, wherein the current state comprises a timeout state and a non-timeout state.
Therefore, whether the SIB stored in the local UE is updated or not is jointly judged according to the first detection result and the current state of the SIB timer, wherein the first detection result indicates whether the changed SIB value of the resident cell is the same as the label value of the SIB stored in the local UE, and the accuracy of judging whether the SIB is updated or not is improved.
In addition, a specific description is further provided herein of an updating method for determining whether to update the SIB locally stored by the UE according to the first detection result and the current state of the SIB timer.
Firstly, when the first detection result is the same, judging that the SIB stored in the local by the UE is not updated;
secondly, when the first detection results are different and the current state of the SIB timer is an overtime state, judging to update the SIB stored in the local by the UE;
and thirdly, when the first detection result is different and the current state of the SIB timer is not overtime, detecting whether the changed label value of the SIB of the resident cell is the same as the previous label value of the SIB stored locally by the UE to obtain a second detection result, and judging whether to update the SIB stored locally by the UE according to the second detection result.
Specifically, when the SIB stored in the local UE is determined to be updated according to the second detection result, wherein,
(1) when the second detection result is the same, judging not to update the SIB stored in the local by the UE;
(2) and when the second detection results are different, judging to update the SIB stored in the local by the UE.
Specifically, if the label value of the SIB stored locally by the UE does not exceed the maximum label value, the previous label value of the SIB stored locally by the UE is a difference between the label value of the SIB stored locally by the UE and 1. Specifically, if the tag value of the SIB stored locally by the UE is 0, the previous tag value of the SIB stored locally by the UE is the maximum tag value.
In this way, the different current states of the SIB timer, the comparison between the changed label value of the SIB of the resident cell and the label value of the SIB saved to the local by the UE, and the comparison between the changed label value of the SIB of the resident cell and the previous label value of the SIB saved to the local by the UE are used as the judgment factors for judging whether to update the SIB saved to the local by the UE, so that the accuracy of judging whether to update the SIB saved to the local by the UE is increased.
The above-described cases are described below with reference to specific examples.
For example, assume that SIB X (e.g., SIB 5) is a region-specific SIB, which includes cell A, cell B, cell C, and cell D (regions where SIB X is all valid SIBs). During the operation of the system, a certain system parameter M in the SIB X needs to be modified, and at time T1, the cell a modifies the value of the parameter M and updates the tag value of the SIB X, where the updated tag value of the SIB X is set to K (it is assumed that K >1 and the tag value of the SIB X before updating is K-1); and the SIB X is not updated due to the excessive workload of the cell B, namely the label value of the SIB X of the cell B is still K-1 at the moment.
Suppose that the current cell where the UE resides is cell a, and the UE receives the network notification, reacquires SIB X from cell a, and stores SIB X locally, and the stored label value of SIB X is K, at this time, the UE starts a pre-configured SIB timer, that is, starts a holding timer of SIB X, and assumes that the timing time of the SIB timer is N1 seconds.
The UE then moves into the coverage of cell B, which does not update SIB X. And the UE obtains the label value of the SIB X of the cell B by reading the SIB1 broadcasted by the cell B, and obtains that the label value of the SIB X of the cell B is K-1. At this time, the label value (K-1) of SIB X of cell B is different from the label value (K) of SIB stored locally by UE, but the label value (K-1) of SIB X of cell B is the same as the previous label value of SIB stored locally by UE, and the SIB timer in UE is in a non-timeout state, it is determined that SIB X is not further updated, and SIB X stored locally by UE is not updated. That is, when the first detection result is different but the current state of the SIB timer is not in the timeout state, if the second detection result is the same, it may be determined that the SIB X stored in the UE is not updated.
After that, cell B modifies parameter M and updates SIB X at time T2 (the time interval between T1 and T2 exceeds N1 seconds), sets its tag value to K, and notifies the UE in the coverage area, at this time, the UE is still in the range of cell B, and after receiving the network notification, the UE reads SIB1 to obtain the tag value of SIB X as K. At this time, although the SIB timer is in the timeout state, if the label value (K) of the SIB X of the cell B is the same as the label value (K) of the SIB stored locally by the UE, it is determined that the SIB X is not updated further, and the SIB X stored locally by the UE is not updated. That is, when the first detection result is the same, it can be directly determined not to update the SIB X stored locally by the UE.
For example, assume that SIB X (e.g., SIB 5) is a region-specific SIB, which includes cell A, cell B, cell C, and cell D (regions where SIB X is all valid SIBs). During the operation of the system, a certain system parameter M in the SIB X needs to be modified, and at time T1, the cell a modifies the value of the parameter M and updates the tag value of the SIB X, where the updated tag value of the SIB X is set to 0 (assuming that the tag value before updating the SIB X is the maximum value V); and the SIB X of the cell C is not updated due to the overlarge workload, namely the label value of the SIB X of the cell C is still V at the moment.
Suppose that the current cell where the UE resides is cell a, and the UE receives the network notification, reacquires SIB X from cell a, and stores SIB X locally, and the stored label value of SIB X is 0, at this time, the UE starts a pre-configured SIB timer, that is, starts a holding timer of SIB X, and assumes that the timing time of the SIB timer is N2 seconds.
The UE then moves into the coverage of cell C at time T3 (time interval T1 and T3 exceeds N2 seconds), at which time cell C does not update SIB X. And the UE reads the SIB1 broadcasted by the cell C to obtain that the SIB X of the cell C has a label value V. At this time, the label value (V) of SIB X of cell C is different from the label value (0) of SIB stored locally by the UE, and the SIB timer in the UE is in a timeout state, and if it is determined that SIB X is further updated, the SIB X stored locally by the UE is updated. That is, when the first detection result is different and the current state of the SIB timer is the timeout state, it is determined to update the SIB stored in the local UE.
At this time, the UE reacquires SIB X in cell C and successfully stores the SIB X locally, the stored SIB X has a tag value of V, and restarts the SIB timer, where the time is set to N2 seconds.
Thereafter, cell C modifies parameter M and updates SIB X at time T4 (the time interval between T3 and T4 is less than N2 seconds), sets the tag value of SIB X to 0, and notifies UE in the coverage area, and at this time, UE still stays in the cell C range, and after receiving the network notification, UE reads SIB1 to obtain the tag value of SIB X as 0. At this time, the label value (0) of SIB X of cell C is different from the label value (V) of SIB X saved locally by UE, and the label value (0) of SIB X of cell C is different from the previous label value (V-1) of SIB X saved locally by UE, and at this time, even though the SIB timer in UE is not in a timeout state, SIB X is determined to be further updated, and then SIB X saved locally by UE is updated. That is, when the first detection result is different and the SIB timer is in the non-timeout state, if the second detection result is also different, it is determined to update the SIB X stored in the local UE.
At this time, the UE reacquires the SIB X in the cell C and stores the SIB X locally, the stored SIB X has a tag value of 0, and restarts the SIB timer.
Example three, assume that SIB X (e.g., SIB 5) is a region-specific SIB, which includes cell a, cell B, cell C, and cell D (regions where SIB X is all valid SIBs). During the operation of the system, a certain system parameter M in the SIB X needs to be modified, and at time T1, the cell a modifies the value of the parameter M and updates the tag value of the SIB X, where the updated tag value of the SIB X is set to K (it is assumed that K >1 and the tag value of the SIB X before updating is K-1); and the cell D synchronously updates the SIB X, namely the label value of the SIB X of the cell D is K at the moment.
Suppose that the current cell where the UE resides is cell a, and the UE receives the network notification, reacquires SIB X from cell a, and stores SIB X locally, and the stored label value of SIB X is K, at this time, the UE starts a pre-configured SIB timer, that is, starts a holding timer of SIB X, and assumes that the timing time of the SIB timer is N3 seconds.
And then the UE moves into the coverage area of the cell D at the time T2, and the UE reads the SIB1 broadcasted by the cell D to obtain the SIB X of the cell D with the label value of K. At this time, since the label value (K) of SIB X of cell D is the same as the label value (K) of SIB stored locally by UE, it is determined that SIB X is not further updated, and SIB X stored locally by UE is not updated. That is, it is also explained that when the first detection result is the same, it can be directly determined not to update the SIB X saved locally by the UE.
After that, at time T3 (the time interval between T1 and T3 is less than N3 seconds), the parameter L of SIB X needs to be modified, the cell D modifies the parameter L and updates SIB X, sets the tag value of SIB X to K +1, and notifies the UE in the coverage, at this time, the UE is still in the range of cell D, and the UE reads SIB1 after receiving the network notification, and obtains the tag value of SIB X to be K + 1. At this time, the label value (K +1) of SIB X of cell D is different from the label value (K) of SIB X saved locally by UE, and the label value (K +1) of SIB X of cell D is different from the previous label value (K-1) of SIB X saved locally by UE, and if SIB X is determined to be further updated even though the SIB timer is not in a timeout state, SIB X saved locally by UE is updated. That is, it is also explained that when the first detection result is different and the SIB timer is in the non-timeout state, if the second detection result is also different, it is determined to update the SIB X stored in the local UE.
At this time, the UE reacquires SIB X in cell D and stores the SIB X locally, the stored SIB X has a tag value of K +1, and restarts the SIB timer.
Therefore, whether the SIB stored in the local by the UE is updated or not is judged by detecting whether the label value of the SIB of the changed resident cell is the same as the label value of the SIB stored in the local by the UE, the current state of the SIB timer and whether the label value of the SIB of the changed resident cell is the same as the previous label value of the SIB stored in the local by the UE, so that the accuracy of the judgment result is improved, the invalid workload of the UE in updating the SIB is avoided, and the power consumption of the UE is reduced.
In addition, further, after determining to update the SIB stored in the local by the UE, the SIB of the changed camping cell may be acquired, and the SIB of the changed camping cell may be stored in the local, and the SIB timer may be restarted, thereby implementing updating of the SIB.
In this way, in this embodiment, by acquiring the SIB with the specific region from the current camping cell and storing the SIB in the local region, starting the SIB timer with the preset configuration, and when it is detected that the cell where the UE camps is changed and the changed camping cell belongs to the intra-region cell, acquiring the tag value of the SIB with the specific region of the changed camping cell, and acquiring the current state of the SIB timer, and finally determining whether to update the SIB stored in the local region for the UE according to the current state of the SIB timer and the tag value of the SIB of the changed camping cell, it is avoided that, in the prior art, when the version of the SIB of the changed camping cell is different from the version of the SIB stored in the local region for the UE, the SIB of the changed camping cell is acquired in real time by the UE and updated, therefore, the problem that the UE is frequently updated to the invalid SIB due to the fact that the base station executes SIB update asynchronization is avoided, invalid workload of the UE is reduced, and power consumption of the UE is reduced.
