Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.

Regarding system information update:

the general System information update refers to System information update except for ETWS (Earthquake and Tsunami Warning System) and CMAS (Commercial Mobile Alert System).

The UE obtains a System Information (SI) update indication through a physical layer Short Message (Short Message) indicated by a Paging Radio Network Temporary Identity (P-RNTI) in Downlink Control Information (DCI). The idle and inactive UEs monitor the system information update indication in a designated Paging Occasion (PO) of each DRX cycle. If the connected UE is configured with the common search space for monitoring paging, the UE monitors the system information update indication at least once every system information modification period, and the monitoring location may be any PO in the modification period.

The UE may always apply the old system information configuration before acquiring the new system information. The system information is configured with a system information modification period, the system information content in the modification period can not be changed, and the system information modification can only start from the starting time of the modification period of the next system information, namely after the UE knows that the system information is changed in the current modification period, new system information is monitored at the starting time of the next modification period. The system information update may be repeatedly transmitted multiple times within the modification period via the scheduling indication. As shown in fig. 1.

System information modification period ═ modificationPeriodCoeff ═ PagingCycle

Wherein, the value ranges of the two parameters are as follows:

modificationPeriodCoeff ENUMERATED{n2,n4,n8,n16}

PagingCycle::＝ENUMERATED{rf32,rf64,rf128,rf256}

regarding system information validity:

the UE needs to store a Master Information Block (MIB), a System Information Block (SIB) 1, or other SIBs acquired in the current camping/serving cell. The effective time of each system information version after the validity is confirmed is at most 3 hours, and the system information version is deleted by the UE after the effective time is exceeded.

The UE may use a valid stored version of the system information other than the MIB and SIB1 after cell reselection, restoring coverage, and receiving system information update indications.

The MIB and SIB1 messages are cell-specific messages (cell-specific), i.e. after the UE accesses or camps on a cell, the correctness and validity of the MIB and SIB1 of the current cell must be guaranteed.

The SIB in any other SI may be configured as system information of a cell-specific (cell-specific) or area-specific (area-specific) level. The cell-level SIB is only used in the cell, and the UE fails after leaving the current cell; the area-level SIBs are commonly used in a set SI area, and one SI area may include one or more cells. Whether the attribute of one SIB is cell-specific or area-specific can be distinguished by the presence or absence of the area scope field corresponding to the SIB in the SIB 1.

The UE may store multiple sets of SIB contents at a cell/area level, and how much contents are stored depends on the memory capacity of the UE. After the UE has mobility between the cells, the stored SIB contents can be sequentially checked, and the successfully checked SIB contents are directly used as effective system information of the UE in the current cell to avoid re-reading; if the SIB required by a certain UE has no corresponding storage content, the UE is required to read the system information of the SIB in the current cell.

The mode for checking the SIB content by the UE specifically comprises the following steps:

for each stored version of SIBs, the SIB currently saved by the UE is considered valid and directly available in the current cell, if:

for the area-specific SIB: if the SIB stored by the UE and the corresponding SIB of the current service cell are associated with the Area scope indication, and the parameters such as a Public Land Mobile Network (PLMN) ID, a System Information Area Identifier (SIAID), a dereferencing tag (valueTag) and the like stored in the SIB are consistent with the parameter dereferencing of the SIB corresponding to the current service cell;

for cell-specific SIB: if the SIB stored by the UE and the corresponding SIB of the current service cell are not related to the area scope indication, and the parameters such as the main PLMN ID, the cell ID and the valueTag stored in the stored SIB are consistent with the values of the corresponding parameters of the SIB of the current service cell.

The parameters involved for SIB version checking are as follows:

1) value tag: the SIB1 contains value tag indication information for each other SIB, and each SIB indicates separate 5-bit value tag content to identify the SIB version number broadcasted by the current cell. SIB6/7/8 for ETWS/CMAS does not require a valuTag indication.

2) PLMN ID: a cell may broadcast a PLMN list where the primary PLMN ID stored in the stored SIB version is compared to the primary PLMN ID in the current serving cell PLMN list for consistency.

3) SIAID: the length is 24bits, and the SIB identifier is unique in PLMN and is only used for identifying the use area range of the SIB of area-specific. Each cell broadcasts only one SIAID, used in conjunction with the PLMN ID.

4) Cell ID (Cell Identity): the length of 36bits is unique in PLMN and is used for identifying the cell.

For energy saving, the network may configure the UE with a relatively long DRX cycle, for example, 10.24 s. The UE may monitor the paging message according to a longer DRX cycle, which may be larger than a system information modification cycle (e.g., modificationperiodconff (4) × paging cycle (64) ═ 2.56s) configured on the network side. The gNB transmits a system information update indication in the previous system information modification period (2.56s), and transmits updated system information in the next 2.56 s. Whereas if the UE receives the paging message in 10.24s, the system information update indication is missed. However, according to the existing mechanism, the UE cannot know whether the system information is updated.

In the technical solution provided in the embodiment of the present application, the UE determines whether the system information is updated (or whether valid system information exists currently) by reading the MIB and/or the SIB1 within the time T (i.e., a preset time) or by reading a signaling containing a special (i.e., a preset) system information update indication within the time T (i.e., a preset time).

Wherein the content of the first and second substances,

optionally, the UE may be one or more of:

the configured dedicated DRX is greater than or equal to a positive integer multiple of 5.12 seconds(s), for example, the configured dedicated DRX is greater than or equal to 5.12s, or the configured dedicated DRX is greater than or equal to 10.24 s;

a power-efficient UE.

Alternatively, the time T may be one of:

-the UE listens for a paging cycle;

-a predefined value;

-a system information update period N; wherein, N is a positive integer, namely a positive integer multiple of the system information updating period;

-a network side configuration value;

-DRX cycle of the UE;

optionally, before the UE initiates the RRC connection and/or recovers the RRC connection, by reading MIB/SIB1, it is obtained whether system information changes;

optionally, when the DRX of the UE is greater than the system information update period, by reading MIB/SIB1, it may be obtained whether the system information is changed; otherwise, the system information update indication may be listened to in the existing system information update period.

Optionally, the UE may read the MIB/SIB1 at intervals of T, with the shortest interval or with the preset time interval from the location where the UE wakes up to monitor the paging, that is, the time when the UE reads the MIB/SIB1 is shortest with the time when the UE wakes up to monitor the paging, or with the preset time interval. For example, before and after the time when the UE wakes up to monitor paging, a plurality of positions for monitoring MIB/SIB1 are arranged, and the time with the shortest interval with the time for monitoring paging is selected as the time when the UE reads MIB/SIB 1; or, the terminal reads the MIB/SIB1 every DRX on, for example, if the configured connected DRX cycle of the UE is 10.24s, the UE reads the MIB/SIB1 every 10.24s to determine whether system information is updated or valid system information exists.

Optionally, when the UE side reads the signaling containing the special system information update indication, the UE side sends the time domain and/or frequency domain position of the signaling containing the special system information update indication according to the network side, and periodically monitors the signaling containing the special system information update indication once or multiple times according to the T time.

Optionally, the network side sends a special signaling of the system information update indication at a fixed time or time domain position every T time, or sends a special signaling of the system information update indication at a time domain and/or frequency domain position of a PDCCH corresponding to the paging for T according to the paging cycle.

Optionally, the signaling containing the special system information update indication contains one or more of the following information:

a system message update indication;

an updated specific SIB identity;

value tag corresponding to the SIB;

the SIB corresponds to an Area identifier (System Information Area ID, SIAID).

Optionally, after monitoring the signaling containing the special system information update indication, the UE side considers that the system information changes, and then reads the system information immediately or in the next system information update period to obtain the system information that needs to be updated.

An illustration of several specific embodiments is given below.

Example 1: the UE in the non-connection state reads the MIB/SIB1 according to the time T to obtain the system information update

The network side configures a system information update period (for example, modificationperiodconfef (4) × PagingCycle (64) ═ 2.56s) in a broadcast manner.

The method comprises the steps that a network side sets energy-saving UE for a certain non-connected state UE, or the DRX period configured for the certain non-connected state UE through a special signaling is 5.12s, the non-connected state UE obtains the latest information of MIB and SIB1 by reading MIB/SIB1 every T time, meanwhile obtains information such as a value tag/area scope indication corresponding to each SIB by reading the information in SIB1, and confirms whether the required system information is updated, if the required system information is updated, the UE can determine whether the UE stores effective system information according to the SIB stored by the current UE and the value tag/area scope indication corresponding to each SIB, and if the SIB stored corresponding system information is stored, the UE directly uses the stored corresponding SIB; if not, the UE acquires the corresponding SIB according to the scheduling information in the SIB 1. Preferably, the UE reads the MIB/SIB1 every T time, and the interval between the UE and the location where the UE wakes up to monitor paging is the shortest as possible, or the interval is a preset duration, so as to reduce power consumption of the UE.

The time T may be one of the following:

-the UE listens for a paging cycle; that is, the UE may read MIB/SIB1 each time it wakes up to listen for a page, confirming whether system information is updated or whether there is valid system information. For example, if the UE wakes up every 5.12s to monitor paging according to the configuration, the UE reads the MIB/SIB1 every 5.12s to determine whether the system information is updated or whether there is valid system information.

-a predefined value; for example, if the protocol predefines T ═ 10.24s, the UE reads MIB/SIB1 every 10.24s, and confirms whether system information is updated and/or whether there is valid system information. Preferably, the UE needs to wake up periodically to monitor paging, for example, the UE wakes up every 5.12s to monitor paging, and when waking up to monitor paging, the UE reads the MIB/SIB1 every 10.24s to determine whether system information is updated or not, or whether valid system information exists, so as to avoid that the UE wakes up to read paging and then turns off a receiver, and subsequently wakes up again to read the MIB/SIB.

-a system information update period N; for example, the system information update period is 2.56s, N may be predefined as 32, or equal to the maximum value of the value tag (the current value tag is 32 max), or the network is configurable and configured as 20, then T is the system information update period N (2.56 x 32 is 81.92s or 2.56 x 20 is 51.2s), and the UE reads the MIB/SIB1 every T (81.92s or 51.2s) to determine whether the system information is updated or not, or whether there is valid system information. Preferably, the time when the UE reads the MIB/SIB1 is the shortest or a preset time interval from the time when the UE wakes up to listen to the paging.

And a network side configuration value, where the network side may configure a value of T according to its own algorithm, for example, the network side configuration T is 20.48 s. The UE reads the MIB/SIB1 every T-20.48 s to determine whether system information is updated and/or whether there is valid system information, and preferably, the time when the UE reads the MIB/SIB1 is the shortest time apart from the time when the UE wakes up to monitor paging or is a preset time apart from the time when the UE wakes up to monitor paging.

Further, in order to ensure that the UE has valid system information when establishing or recovering the RRC connection, if the time from the last time when the UE determines that the system information is changed is longer than the system information update period, before the UE initiates the RRC connection and/or recovers the RRC connection, the UE reads MIB/SIB1 to obtain whether the system information is changed and/or whether valid system information exists.

Further, when the DRX corresponding to the UE is greater than the system information update period, it may be adopted to obtain whether the system information changes and/or whether there is valid system information by reading MIB/SIB1 at intervals of T; otherwise, the system information update indication is monitored according to the existing system information update cycle (i.e. the non-connected UE monitors the system information update indication in a designated Paging Occasion (PO) of each DRX cycle).

The method flow at the terminal side in this embodiment is also applicable to the apparatus at the terminal side provided in this embodiment, that is, the apparatus at the terminal side provided in this embodiment may execute the method flow at the terminal side in this embodiment; similarly, the method flow of the network side in this embodiment is also applicable to the device of the network side provided in this embodiment, that is, the device of the network side provided in this embodiment may execute the method flow of the network side in this embodiment.

Example 2: and the connected UE reads the MIB/SIB1 according to the time T to obtain system information update.

If the network side sets a certain connected UE as an energy-saving UE, or the configured connected DRX period is longer (10.24s), the connected UE reads the MIB/SIB1 every T time. The method comprises the steps of obtaining the latest information of MIB and SIB1 by reading MIB/SIB1, obtaining information such as required value tag/area scope indication corresponding to each SIB by reading the information in SIB1, confirming whether the required system information is updated, if the required system information is updated, determining whether the UE stores effective system information according to the SIB stored by the UE currently and the information such as the value tag/area scope indication corresponding to each SIB by the UE, and if the required system information is updated, directly using the stored corresponding SIB by the UE; if not, the UE acquires the corresponding SIB according to the scheduling information in the SIB 1.

The time T may be one of the following:

-a predefined value; the same as example 1;

-a system information update period N; the same as example 1; preferably, the UE can read the MIB/SIB1 when the DRX on is performed, so that the power consumption of the UE is reduced;

-a network side configuration value; the same as example 1; preferably, the UE can read the MIB/SIB1 when the DRX on is performed, so that the power consumption of the UE is reduced;

-DRX cycle of the UE; for example, the configured connected DRX cycle of the UE is 10.24s, the UE reads MIB/SIB1 every 10.24s to determine whether system information is updated and/or whether there is valid system information. Preferably, the UE may read MIB/SIB1 to confirm whether system information is updated every DRX on.

Further, when the DRX corresponding to the UE is greater than the system information update period and a public search space for monitoring paging is configured, it is only to read MIB/SIB1 at intervals of time T to obtain whether system information changes and/or whether valid system information exists; otherwise, the system information update indication is monitored according to the existing system information update period (i.e. if the connected UE is configured to monitor the common search space for paging, the system information update indication is monitored at least once every system information modification period, and the monitoring location may be any PO in the modification period).

Example 3: the system information update is obtained by signaling containing a system information update indication.

It should be noted that, in the above embodiment, the network side also needs to transmit the MIB/SIB1, but how to transmit the MIB/SIB1 may be implemented by using the prior art, and therefore is not described. In embodiment 3, the network side sends the signaling containing the system information update indication, which is a new behavior and is only notified for the special UE (e.g., the configured terminal with the DRX cycle of the dedicated discontinuous reception being greater than or equal to positive integer multiple of 5.12s, and/or the energy-saving terminal).

The network side sends a special signaling of system information updating indication at a fixed time and/or time domain position every T time, or sends a special signaling of system information updating indication at a PDCCH time domain and/or frequency domain position corresponding to the sending paging for T according to the paging cycle.

Note that the signaling of the system information update indication is only valid for the configured dedicated DRX greater than or equal to 5.12s (or 10.24s) and/or for the energy-saving UE, and is a different indication from the SI update indication in the existing system. The signaling may also be included in the physical layer Short Message indicated by the P-RNTI in the DCI. The signaling may only carry a system information update indication. Optionally, the signaling may further include one or more of the following information:

-updated specific SIB, value tag corresponding to this SIB, area identity (SIAID) corresponding to this SIB.

The time T may be one of the following:

-a predefined value; the same as example 1;

-a system information update period N; the same as example 1;

-a network side configuration value; the same as in example 1.

The configured DRX dedicated to the UE is greater than or equal to 5.12s (or 10.24s), or the UE is energy-saving, and periodically monitors one or more times a signaling including a preset (special, that is, specifically set for the terminal in this embodiment) system information update indication according to a time domain and/or a frequency domain position where the network side sends the signaling including the special system information update indication, according to the time T. After monitoring the signaling containing the special system information updating indication, the UE side considers that the system information is changed, and then immediately or in the next system information updating period (the system information updating period confirmed according to the existing protocol configuration) reads the system information (the system information reading process is according to the existing protocol process, and is not described here any more), and obtains the system information that needs to be updated.

Further, when the signaling containing the special system information update indication may further contain one or more of the following information:

-updated specific SIB identities; value tag corresponding to the SIB; the region identification (SIAID) corresponding to the SIB.

The UE side may determine whether the required system information is updated according to monitoring a signaling including a special system information update indication (for example, value tag and/or area identifier, and determine whether the corresponding SIB is updated), if the update occurs, and for the required system information, the UE determines that a corresponding version does not exist (corresponding to a case that the received update indication signaling includes a specific SIB + value tag + area identifier), or the UE cannot determine whether a valid version exists (corresponding to a case that the received update indication signaling includes only a specific SIB identifier or only a system information update indication), and immediately or in a next system information update period (a system information update period confirmed according to an existing protocol configuration), reads the system information, and obtains the required updated system information.

Further, in order to ensure that the UE has valid system information when establishing the RRC connection or recovering the RRC connection, if the time from the last time when the UE determines that the system information is changed is greater than the system information update period, before the UE initiates the RRC connection and/or recovers the RRC connection, the UE reads MIB/SIB1 to obtain whether the system information is changed. It should be noted that, even if the UE obtains the system message update by monitoring the signaling of the special system information update indication, before the UE initiates the radio resource control RRC connection and/or recovers the RRC connection, it may also determine whether the system information is changed by reading the MIB/SIB 1.
