- RRC_INACTIVE the RRC deactivated
- RRC_CONNECTED the RRC connected
- RRC_IDLE Mobility is terminal-based cell selection reselection, paging is initiated by the Core Network (CN), and the paging area is configured by the CN. There is no access stratum (Access Stratum, AS) context of the terminal on the base station side. There is no RRC connection.
- CN Core Network
- AS Access Stratum
- RRC_INACTIVE Mobility is terminal-based cell selection reselection, there is a connection between CN-NR, UE AS context exists on a certain base station, paging is triggered by Radio Access Network (RAN), RAN-based The paging area is managed by the RAN, and the network side knows the location of the terminal based on the paging area level of the RAN.
- RAN Radio Access Network
- RRC_CONNECTED There is an RRC connection, and the base station and terminal have UE AS context.
- the network side knows that the location of the terminal is at the specific cell level. Mobility is the mobility controlled by the network side. Data can be transmitted between the terminal and the base station.
- the main function of paging is to enable the network to page the UE in the RRC IDLE or RRC INACTIVE state of the UE through a paging message, or to notify the UE of a system message change or earthquake, tsunami/public through a short message.
- Early warning information (applicable to all RRC states of the UE, including the connected state).
- Paging includes a Physical Downlink Control Channel (PDCCH) scrambled by a Paging Radio Network Temporary Identity (P-RNTI), and a physical downlink shared shared by the PDCCH.
- P-RNTI Paging Radio Network Temporary Identity
- Channel Physical Downlink Shared Channel, PDSCH.
- Paging message is transmitted in PDSCH, and short message is 8bit in PDCCH.
- the UE can monitor the paging channel discontinuously, that is, the paging DRX mechanism is used.
- the UE Under the Paging DRX mechanism, the UE only needs to monitor paging during a paging occasion (Paging Occasion, PO) in each Discontinuous Reception (DRX) cycle (cycle).
- PO is a series of PDCCH listening occasions and it can consist of multiple time slots.
- Paging Frame, PF refers to a radio frame (fixed at 10 ms), and the radio frame may contain multiple POs or start positions of multiple POs.
- the cycle of Paging DRX is determined by the common cycle in the system broadcast and the dedicated cycle configured in the high-level signaling (Non-Access Stratum (NAS) signaling), and the UE takes the minimum cycle of the two as the Paging Cycle cycle.
- NAS Non-Access Stratum
- a paging DRX cycle can have multiple POs, and the position where the UE monitors the PO is related to the identity (Identity, ID) of the UE.
- ID identity
- SFN System Frame Number
- the number (Index(i_s)) of the PO within a PF is determined by the following Equation 2:
- T represents the DRX cycle in which the UE receives paging.
- the network will broadcast a default DRX cycle. If the RRC/higher layer configures a UE-specific DRX cycle for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the RRC/higher layer is used as the UE's DRX cycle. . If the RRC/higher layer does not configure the UE-specific DRX cycle for the UE, the DRX cycle broadcast by the network is used as the DRX cycle of the UE.
- N represents the number of PFs included in one DRX cycle. Ns represents the number of POs contained in a PF.
- PF_offset represents a time domain offset used to determine PF.
- UE_ID is used to represent 5G-S-TMSI mod 1024.
- the position of PF and the index of PO can be known in a paging DRX cycle.
- PO is composed of multiple PDCCH monitoring occasions (monitoring occasions), one PO contains X PDCCH monitoring occasions, X is equal to the actual transmission of the synchronization signal block (Synchronization Signal Block, SSB) broadcast in the master information block (Master Information Block, MIB) quantity.
- SSB Synchronization Signal Block
- MIB Master Information Block
- the UE After the UE knows the index of the PF, PO, and the number of PDCCH monitoring occasions in the PO, it only needs to know the starting position of the first PDCCH monitoring occasion of the PO through the relevant configuration parameters.
- the starting position can be passed through high-level signaling configuration, or based on PO index.
- the UE blindly checks the paging message according to the determined PO.
- the paging DRX mechanism is also used for the UE in the RRC_IDLE state or the RRC_INACTIVE state.
- the UE under the Paging DRX mechanism, the UE only needs to monitor paging during one PO in each DRX cycle.
- the LTE system also defines the concepts of PF and PO. Different from the NR system, in the LTE system, PO is a subframe in the corresponding PF.
- T represents the DRX cycle of the UE receiving paging, which is determined as follows:
- the value of T is 5.12s. Otherwise, if the upper layer configures the UE-specific DRX cycle for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the higher layer is used as T. If the higher layer does not configure the UE-specific DRX cycle for the UE, the DRX cycle broadcast by the network is taken as T.
- the upper layer For a UE in the RRC INACTIVE state, if the upper layer does not configure eDRX for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by RRC/high layer is used as T. Otherwise, if the upper layer configures eDRX for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the RRC/high layer is used as T during the paging time window (Paging Time Window, PTW); In addition, the UE-specific DRX cycle configured by RRC is taken as T.
- Paging Time Window Paging Time Window
- LTE introduces the eDRX mechanism for such terminals to support more A large paging period, that is, the paging period is greater than 256 SFNs.
- the minimum value of the eDRX cycle configured by the upper layer is 5.12s.
- the PTW is exclusive to the UE, and is determined according to the paging super system frame number (paging H-SFN, PH), a start time point (PTW_start) and an end time point (PTW_end) located in the PH.
- PH is an H-SFN that meets the following conditions:
- UE_ID_H is obtained based on the hash ID, and T eDRX,H is an eDRX period in superframe units, which is configured by an Access and Mobility Management Function (AMF) entity.
- AMF Access and Mobility Management Function
- PTW_start is the starting radio frame number of the PTW, which is the SFN that satisfies the following conditions:
- PTW_end is the end radio frame number of the PTW, which is the SFN that satisfies the following conditions:
- SFN (PTW_start+L*100-1) mod 1024; wherein, L is the window length of PTW, which is configured by AMF.
- the 3GPP RAN Plenary agreed to study the low-capability NR terminal project (RP-193238).
- one of the goals of this project is: for the RedCap terminal, by introducing the eDRX mechanism in the idle state or the deactivated state, to achieve the purpose of saving power and prolonging the battery life of the terminal.
- the DRX cycle is extended to 10.24s as the baseline. Whether it needs to support a larger DRX cycle can be discussed later;
- RAN2 needs to study whether the eDRX cycle in the RRC IDLE state and the RRC INACTIVE state needs to support a value less than 5.12s;
- the baselne For UEs in RRC IDLE state and RRC INACTIVE state, if the maximum DRX cycle that can be supported exceeds 10.24s, the eDRX mechanism with an eDRX cycle exceeding 10.24s in LTE (that is, using PTW, PH, etc.) is used as the baselne;
- PTW and PH are not used for paging monitoring
- system message update period In LTE and NR systems, the concept of system message update period is used.
- the network When the network wants to update the system message, the network first repeatedly sends the system message update indication in the nth system message update period, and then repeatedly sends the updated system message in the n+1th system message update period, as shown in Figure 2 Show.
- system message update period may be determined according to the following formula 3.
- m modificationPeriodCoeff*defaultPagingCycle, where m represents the system message update cycle, modificationPeriodCoeff represents the system message update cycle coefficient, defaultPagingCycle represents the default paging cycle, and the two parameters, modificationPeriodCoeff and defaultPagingCycle, are determined by network broadcast.
- the eDRX acquisition cycle is introduced.
- the UE For a UE in the RRC IDLE state and the configured DRX cycle is not greater than the system message update cycle, if the UE receives a system message update indication (systemInfoModification) in the nth system message update cycle, the UE is in the n+1th system message update cycle.
- the update cycle receives updated system messages.
- the UE receives a system message update indication (systemInfoModification-eDRX) in the nth eDRX acquisition cycle, the UE obtains the system information in the n+1th eDRX acquisition cycle. Periodically receive updated system messages.
- system message update cycle is applicable to the update of system messages other than system information blocks (System Information Block, SIB) 6, SIB7, SIB8, and positioning assistance data.
- SIB System Information Block
- the UE uses the eDRX acquisition cycle to obtain updated system messages; and when the UE is in the RRC INACTIVE state, how does the UE determine The period for obtaining updated system messages is not specified in the current standard.
- the UE determines the period for obtaining the updated system message is also a problem that needs to be solved.

为便于更好的理解本申请实施例,对本申请相关的5G NR寻呼(paging)机制进行说明。In order to facilitate a better understanding of the embodiments of the present application, the 5G NR paging mechanism related to the present application is described.
寻呼(paging)主要功能是使得网络能在UE的RRC IDLE或者RRC INACTIVE状态通过寻呼消息(paging message)寻呼UE,或者通过短消息(short message)通知UE系统消息变更或者地震海 啸/公共预警信息(适用于UE所有RRC状态,包括连接态)。The main function of paging is to enable the network to page the UE in the RRC IDLE or RRC INACTIVE state of the UE through a paging message, or to notify the UE of a system message change or earthquake, tsunami/public through a short message. Early warning information (applicable to all RRC states of the UE, including the connected state).
寻呼(paging)包括由寻呼无线网络临时标识符(Paging Radio Network Temporary Identity,P-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel,PDCCH),以及由该PDCCH调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。Paging message在PDSCH中传输,short message为8bit在PDCCH中。Paging includes a Physical Downlink Control Channel (PDCCH) scrambled by a Paging Radio Network Temporary Identity (P-RNTI), and a physical downlink shared shared by the PDCCH. Channel (Physical Downlink Shared Channel, PDSCH). Paging message is transmitted in PDSCH, and short message is 8bit in PDCCH.
对于处于RRC_IDLE状态或者RRC_INACTIVE状态的UE,由于UE与网络之间没有其他的数据通信,为了终端省电,UE可以非连续的监听寻呼信道,即采用paging DRX机制。在Paging DRX机制下,UE只需要在每个非连续接收(Discontinuous Reception,DRX)周期(cycle)内的一个寻呼时机(Paging Occasion,PO)期间监听paging。PO是一系列PDCCH监听时机同时它可以由多个时隙组成。另外还有寻呼帧(Paging Frame,PF)的概念,PF指的是一个无线帧(固定10ms),该无线帧可以包含多个PO或者是多个PO的起始位置。For the UE in the RRC_IDLE state or the RRC_INACTIVE state, since there is no other data communication between the UE and the network, in order to save the power of the terminal, the UE can monitor the paging channel discontinuously, that is, the paging DRX mechanism is used. Under the Paging DRX mechanism, the UE only needs to monitor paging during a paging occasion (Paging Occasion, PO) in each Discontinuous Reception (DRX) cycle (cycle). PO is a series of PDCCH listening occasions and it can consist of multiple time slots. In addition, there is a concept of a paging frame (Paging Frame, PF). PF refers to a radio frame (fixed at 10 ms), and the radio frame may contain multiple POs or start positions of multiple POs.
Paging DRX的周期由系统广播中的公共周期和高层信令(非接入层(Non-Access Stratum,NAS)信令)中配置的专属周期共同决定,UE取两者中的最小周期为Paging Cycle的周期。从网络角度来看,一个paging DRX cycle可以有多个PO,UE监听PO的位置跟该UE的标识(Identity,ID)有关,具体的某一个UE在一个Paging DRX中的PF和PO的确定方式可以如下:The cycle of Paging DRX is determined by the common cycle in the system broadcast and the dedicated cycle configured in the high-level signaling (Non-Access Stratum (NAS) signaling), and the UE takes the minimum cycle of the two as the Paging Cycle cycle. From the network point of view, a paging DRX cycle can have multiple POs, and the position where the UE monitors the PO is related to the identity (Identity, ID) of the UE. The specific way of determining the PF and PO of a certain UE in a Paging DRX Can be as follows:
PF的系统帧号(System Frame Number,SFN)编号通过以下公式1确定:The System Frame Number (SFN) number of PF is determined by the following formula 1:
(SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) 公式1(SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) Formula 1
PO位于一个PF内的编号(Index(i_s))通过以下公式2确定:The number (Index(i_s)) of the PO within a PF is determined by the following Equation 2:
i_s=floor(UE_ID/N)mod Ns 公式2i_s=floor(UE_ID/N)mod Ns Formula 2
其中,T表示UE接收paging的DRX周期。网络会广播一个默认的DRX周期,如果RRC/高层为UE配置了UE专属的DRX周期,则将网络广播的DRX周期和RRC/高层配置的UE专属的DRX周期中最小的作为该UE的DRX周期。如果RRC/高层没有为UE配置UE专属的DRX周期,则将网络广播的DRX周期作为该UE的DRX周期。N表示一个DRX周期内包含的PF个数。Ns表示一个PF内包含的PO个数。PF_offset表示用于确定PF的一个时域偏移量。UE_ID用于表示5G-S-TMSI mod 1024。Among them, T represents the DRX cycle in which the UE receives paging. The network will broadcast a default DRX cycle. If the RRC/higher layer configures a UE-specific DRX cycle for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the RRC/higher layer is used as the UE's DRX cycle. . If the RRC/higher layer does not configure the UE-specific DRX cycle for the UE, the DRX cycle broadcast by the network is used as the DRX cycle of the UE. N represents the number of PFs included in one DRX cycle. Ns represents the number of POs contained in a PF. PF_offset represents a time domain offset used to determine PF. UE_ID is used to represent 5G-S-TMSI mod 1024.
对于一个UE,根据上述公式1和公式2,可以知道在一个paging DRX cycle中,PF的位置,以及PO的索引(index)。PO是由多个PDCCH监听时机(monitoring occasion)组成,一个PO包含X个PDCCH monitoring occasion,X等于主信息块(Master Information Block,MIB)中广播的同步信号块(Synchronization Signal Block,SSB)实际发送的数量。For a UE, according to the above formula 1 and formula 2, the position of PF and the index of PO can be known in a paging DRX cycle. PO is composed of multiple PDCCH monitoring occasions (monitoring occasions), one PO contains X PDCCH monitoring occasions, X is equal to the actual transmission of the synchronization signal block (Synchronization Signal Block, SSB) broadcast in the master information block (Master Information Block, MIB) quantity.
UE知道PF,PO的index之后,以及PO中PDCCH monitoring occasion的数量之后,只需要通过相关配置参数知道该PO的第一个PDCCH monitoring occasion的起始位置就行,该起始位置可以通过高层信令配置,或者基于PO index来得到。UE根据确定的PO来盲检paging消息。After the UE knows the index of the PF, PO, and the number of PDCCH monitoring occasions in the PO, it only needs to know the starting position of the first PDCCH monitoring occasion of the PO through the relevant configuration parameters. The starting position can be passed through high-level signaling configuration, or based on PO index. The UE blindly checks the paging message according to the determined PO.
为便于更好的理解本申请实施例,对本申请相关的LTE paging机制进行说明。For better understanding of the embodiments of the present application, the LTE paging mechanism related to the present application is described.
在LTE系统中,对于处于RRC_IDLE状态或者RRC_INACTIVE状态的UE,也采用paging DRX机制。与NR系统相同,在Paging DRX机制下,UE只需要在每个DRX cycle周期内的一个PO期间监听paging。LTE系统同样也定义了PF,PO的概念,与NR系统不同的是,在LTE系统中,PO是对应PF内的一个子帧。In the LTE system, the paging DRX mechanism is also used for the UE in the RRC_IDLE state or the RRC_INACTIVE state. Like the NR system, under the Paging DRX mechanism, the UE only needs to monitor paging during one PO in each DRX cycle. The LTE system also defines the concepts of PF and PO. Different from the NR system, in the LTE system, PO is a subframe in the corresponding PF.
与NR系统相同,在LTE系统中,对于处于RRC IDLE态或RRC INACTIVE态的UE,该UE根据UE ID,T等参数计算自己的PO。其中,T表示UE接收paging的DRX周期,其确定方式如下:Similar to the NR system, in the LTE system, for the UE in the RRC IDLE state or the RRC INACTIVE state, the UE calculates its own PO according to parameters such as UE ID and T. Among them, T represents the DRX cycle of the UE receiving paging, which is determined as follows:
对于RRC IDLE态的UE,如果高层给该UE配置了eDRX且配置的eDRX周期为5.12s,则T取值为5.12s。否则,如果高层为UE配置了UE专属的DRX周期,则将网络广播的DRX周期和高层配置的UE专属的DRX周期中最小的作为T。如果高层没有为UE配置UE专属的DRX周期,则将网络广播的DRX周期作为T。For a UE in the RRC IDLE state, if the upper layer configures eDRX for the UE and the configured eDRX cycle is 5.12s, the value of T is 5.12s. Otherwise, if the upper layer configures the UE-specific DRX cycle for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the higher layer is used as T. If the higher layer does not configure the UE-specific DRX cycle for the UE, the DRX cycle broadcast by the network is taken as T.
对于RRC INACTIVE态的UE,如果高层没有给该UE配置eDRX,则将网络广播的DRX周期和RRC/高层配置的UE专属的DRX周期中最小的作为T。否则,如果高层为UE配置了eDRX,则在寻呼时间窗(Paging Time Window,PTW)期间将网络广播的DRX周期和RRC/高层配置的UE专属的DRX周期中最小的作为T;在PTW之外,将RRC配置的UE专属的DRX周期作为T。For a UE in the RRC INACTIVE state, if the upper layer does not configure eDRX for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by RRC/high layer is used as T. Otherwise, if the upper layer configures eDRX for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the RRC/high layer is used as T during the paging time window (Paging Time Window, PTW); In addition, the UE-specific DRX cycle configured by RRC is taken as T.
为便于更好的理解本申请实施例,对本申请相关的LTE eDRX机制进行说明。In order to better understand the embodiments of the present application, the LTE eDRX mechanism related to the present application is described.
考虑到窄带物联网(Narrow Band Internet of Things,NB-IoT)和增强的机器类型通信(Enhanced Machine Type Communication,eMTC)等类型终端的业务类型较为单一且业务量活跃度很低,这些终端在大部分时间都处于非连接态,同时考虑到这些终端的业务对时延要求不敏感,为了这类终端能够在非连接态下进一步省电,LTE中针对这类终端引入了eDRX机制从而可以支持更大的paging周期, 即paging周期大于256个SFN。在LTE中,高层配置eDRX周期的最小值为5.12s。Considering that the Narrow Band Internet of Things (NB-IoT) and Enhanced Machine Type Communication (eMTC) and other types of terminals have relatively single business types and low business activity, these terminals are in large scale. Part of the time is in the disconnected state, and considering that the services of these terminals are not sensitive to delay requirements, in order to further save power for such terminals in the disconnected state, LTE introduces the eDRX mechanism for such terminals to support more A large paging period, that is, the paging period is greater than 256 SFNs. In LTE, the minimum value of the eDRX cycle configured by the upper layer is 5.12s.
对于配置了eDRX的UE,如果该UE的eDRX周期为5.12s,则UE基于T=5.12s计算自己对应的PO。如果该UE的eDRX周期大于或等于1个超系统帧号(Hyper System Frame Number,H-SFN),则UE在一个eDRX周期内的PTW时间窗内在自己的PO上监听P-RNTI加扰的PDCCH。其中,PTW为UE专属的,其根据寻呼超系统帧号(paging H-SFN,PH),位于该PH内的一个起始时间点(PTW_start)和一个结束时间点(PTW_end)确定。For a UE configured with eDRX, if the eDRX period of the UE is 5.12s, the UE calculates its corresponding PO based on T=5.12s. If the eDRX cycle of the UE is greater than or equal to 1 Hyper System Frame Number (H-SFN), the UE monitors the PDCCH scrambled by P-RNTI on its own PO within the PTW time window within one eDRX cycle. . The PTW is exclusive to the UE, and is determined according to the paging super system frame number (paging H-SFN, PH), a start time point (PTW_start) and an end time point (PTW_end) located in the PH.
PH为满足以下条件的H-SFN:PH is an H-SFN that meets the following conditions:
H-SFN mod TeDRX,H=(UE_ID_H mod T
eDRX,H);
H-SFN mod TeDRX, H=(UE_ID_H mod TeDRX, H );
其中,UE_ID_H基于哈希ID得到,T
eDRX,H为以超帧为单位的eDRX周期,由接入与移动性管理功能(Access and Mobility Management Function,AMF)实体配置。
Wherein, UE_ID_H is obtained based on the hash ID, and T eDRX,H is an eDRX period in superframe units, which is configured by an Access and Mobility Management Function (AMF) entity.
PTW_start为PTW的起始无线帧号,为满足以下条件的SFN:PTW_start is the starting radio frame number of the PTW, which is the SFN that satisfies the following conditions:
SFN=256*i
eDRX,i
eDRX=floor(UE_ID_H/T
eDRX,H)mod 4。
SFN=256*i eDRX , i eDRX =floor(UE_ID_H/T eDRX,H )mod 4.
PTW_end为PTW的结束无线帧号,为满足以下条件的SFN:PTW_end is the end radio frame number of the PTW, which is the SFN that satisfies the following conditions:
SFN=(PTW_start+L*100-1)mod 1024;其中,L为PTW的窗长,由AMF配置。SFN=(PTW_start+L*100-1) mod 1024; wherein, L is the window length of PTW, which is configured by AMF.
为便于更好的理解本申请实施例,对本申请相关的NR降低能力(Reduced Capbility,RedCap)终端eDRX机制进行说明。In order to facilitate a better understanding of the embodiments of the present application, an eDRX mechanism of an NR reduction capability (Reduced Capbility, RedCap) terminal related to the present application is described.
在版本17(release17,R17)NR的工作项目中,3GPP RAN全会同意了研究低能力的NR终端项目(RP-193238)。其中,该项目的一个目标是:针对RedCap终端,通过引入空闲态或去激活态下的eDRX机制,来达到终端省电,延长电池寿命的目的。In the release 17 (release17, R17) NR work item, the 3GPP RAN Plenary agreed to study the low-capability NR terminal project (RP-193238). Among them, one of the goals of this project is: for the RedCap terminal, by introducing the eDRX mechanism in the idle state or the deactivated state, to achieve the purpose of saving power and prolonging the battery life of the terminal.
目前针对RedCap终端的eDRX机制已形成如下结论:At present, the eDRX mechanism for RedCap terminals has reached the following conclusions:
对于RRC IDLE态,将DRX周期扩展至大于2621.44s作为基线(baseline),同时还可以研究是否需要支持更大的eDRX周期(例如,10485.76s);For the RRC IDLE state, extend the DRX cycle to greater than 2621.44s as the baseline, and also study whether it needs to support a larger eDRX cycle (for example, 10485.76s);
对于RRC INACTIVE态,将DRX周期扩展至10.24s作为baseline,是否需要支持更大的DRX周期可以待后续讨论;For the RRC INACTIVE state, the DRX cycle is extended to 10.24s as the baseline. Whether it needs to support a larger DRX cycle can be discussed later;
RAN2需要研究对于RRC IDLE态和RRC INACTIVE态的eDRX周期是否需要支持小于5.12s的取值;RAN2 needs to study whether the eDRX cycle in the RRC IDLE state and the RRC INACTIVE state needs to support a value less than 5.12s;
对于RRC IDLE态和RRC INACTIVE态的UE,如果可以支持的最大DRX周期超过了10.24s,则将LTE中eDRX周期超过10.24s的eDRX机制(即,使用PTW,PH等)作为baselne;For UEs in RRC IDLE state and RRC INACTIVE state, if the maximum DRX cycle that can be supported exceeds 10.24s, the eDRX mechanism with an eDRX cycle exceeding 10.24s in LTE (that is, using PTW, PH, etc.) is used as the baselne;
对于RRC IDLE态和RRC INACTIVE态的UE,如果eDRX周期小于10.24s,则寻呼监听不使用PTW和PH等;For UEs in RRC IDLE state and RRC INACTIVE state, if the eDRX period is less than 10.24s, PTW and PH are not used for paging monitoring;
对于RRC IDLE态和RRC INACTIVE态的UE,如果eDRX周期等于10.24s,则基本假设是不使用PTW和PH,但也不排除其他方案。For UEs in RRC IDLE state and RRC INACTIVE state, if the eDRX cycle is equal to 10.24s, the basic assumption is that PTW and PH are not used, but other solutions are not excluded.
为便于更好的理解本申请实施例,对本申请相关的系统消息更新周期进行说明。To facilitate a better understanding of the embodiments of the present application, the system message update cycle related to the present application is described.
在LTE和NR系统中,使用了系统消息更新周期的概念。当网络要更新系统消息时,网络先在第n个系统消息更新周期内重复发送系统消息更新指示,接着在第n+1个系统消息更新周期内重复发送更新后的系统消息,如图2所示。系统消息更新周期的边界定义为满足SFN mod m=0的SFN,其中,m为一个系统消息更新周期包含的SFN个数。In LTE and NR systems, the concept of system message update period is used. When the network wants to update the system message, the network first repeatedly sends the system message update indication in the nth system message update period, and then repeatedly sends the updated system message in the n+1th system message update period, as shown in Figure 2 Show. The boundary of the system message update period is defined as the SFN satisfying SFN mod m=0, where m is the number of SFNs included in one system message update period.
可选地,系统消息更新周期可以根据如下公式3确定。Optionally, the system message update period may be determined according to the following formula 3.
m=modificationPeriodCoeff*defaultPagingCycle,其中,m表示系统消息更新周期,modificationPeriodCoeff表示系统消息更新周期系数,defaultPagingCycle表示默认寻呼周期,modificationPeriodCoeff和defaultPagingCycle这2个参数都是网络广播确定。m=modificationPeriodCoeff*defaultPagingCycle, where m represents the system message update cycle, modificationPeriodCoeff represents the system message update cycle coefficient, defaultPagingCycle represents the default paging cycle, and the two parameters, modificationPeriodCoeff and defaultPagingCycle, are determined by network broadcast.
在LTE系统中,由于引入了eDRX机制,为了能够使处于RRC IDEL态且配置的DRX周期大于系统消息更新周期的UE能够接收到系统消息更新指示,引入了eDRX获取周期。eDRX获取周期的边界定义为满足H-SFN mod 256=0的H-SFN。对于NB-IoT,eDRX获取周期的边界定义为满足H-SFN mod 1024=0的H-SFN。对于处于RRC IDLE态且配置的DRX周期不大于系统消息更新周期的UE,如果该UE在第n个系统消息更新周期接收到系统消息更新指示(systemInfoModification),则UE在第n+1个系统消息更新周期接收更新后的系统消息。对于处于RRC IDLE态且配置的DRX周期大于系统消息更新周期的UE,如果该UE在第n个eDRX获取周期接收到系统消息更新指示(systemInfoModification-eDRX),则UE在第n+1个eDRX获取周期接收更新后的系统消息。In the LTE system, due to the introduction of the eDRX mechanism, in order to enable UEs in the RRC IDEL state and the configured DRX cycle is greater than the system message update cycle to receive the system message update indication, the eDRX acquisition cycle is introduced. The boundary of the eDRX acquisition period is defined as the H-SFN satisfying H-SFN mod 256=0. For NB-IoT, the boundary of the eDRX acquisition period is defined as the H-SFN satisfying H-SFN mod 1024=0. For a UE in the RRC IDLE state and the configured DRX cycle is not greater than the system message update cycle, if the UE receives a system message update indication (systemInfoModification) in the nth system message update cycle, the UE is in the n+1th system message update cycle. The update cycle receives updated system messages. For a UE in the RRC IDLE state and the configured DRX cycle is greater than the system message update cycle, if the UE receives a system message update indication (systemInfoModification-eDRX) in the nth eDRX acquisition cycle, the UE obtains the system information in the n+1th eDRX acquisition cycle. Periodically receive updated system messages.
在NR系统中,系统消息更新周期适用于除了系统信息块(System Information Block,SIB)6,SIB7,SIB8,以及定位辅助数据以外的系统消息的更新。In the NR system, the system message update cycle is applicable to the update of system messages other than system information blocks (System Information Block, SIB) 6, SIB7, SIB8, and positioning assistance data.
在LTE系统中,对于eDRX周期大于系统消息更新周期的UE,当该UE处于RRC IDLE态时, UE使用eDRX获取周期来获取更新的系统消息;而当该UE处于RRC INACTIVE态是,UE如何确定获取更新的系统消息的周期,目前标准中并没有明确。同样的,在NR系统中,对于eDRX周期大于系统消息更新周期的RedCap终端,当该UE处于RRC INACTIVE态时,UE如何确定获取更新的系统消息的周期,也是需要解决的问题。In the LTE system, for a UE whose eDRX cycle is greater than the system message update cycle, when the UE is in the RRC IDLE state, the UE uses the eDRX acquisition cycle to obtain updated system messages; and when the UE is in the RRC INACTIVE state, how does the UE determine The period for obtaining updated system messages is not specified in the current standard. Similarly, in the NR system, for a RedCap terminal whose eDRX period is greater than the system message update period, when the UE is in the RRC INACTIVE state, how the UE determines the period for obtaining the updated system message is also a problem that needs to be solved.
基于上述问题,本申请提出了一种确定获取更新的系统消息的周期的方案,处于RRC去激活态的终端可以确定获取系统消息更新指示以及更新后的系统消息的周期,从而优化系统消息的传输。Based on the above problems, the present application proposes a solution for determining the period for acquiring updated system messages. A terminal in the RRC deactivated state can determine the period for acquiring system message update instructions and updated system messages, thereby optimizing the transmission of system messages. .

也即,在一种实现方式中,对于处于RRC去激活态的终端设备,如果网络设备给终端设备配置了CN eDRX周期,并且CN eDRX周期大于系统消息更新周期。此种情况下,如果网络设备通过RRC信令给终端设备配置了RAN DRX周期,且RAN DRX周期大于系统消息更新周期,则终端设备使用第一eDRX获取周期来获取更新的系统消息。如果网络设备通过RRC信令给终端设备配置了RAN DRX周期,且RAN DRX周期小于或等于系统消息更新周期,则终端设备使用系统消息更新周期来获取更新的系统消息。如果网络设备没有通过RRC信令给终端设备配置RAN DRX周期,则终端设备使用第一eDRX获取周期来获取更新的系统消息。That is, in an implementation manner, for a terminal device in the RRC deactivated state, if the network device configures a CN eDRX cycle for the terminal device, and the CN eDRX cycle is greater than the system message update cycle.

For example, for an LTE system, the first eDRX acquisition period is an eDRX acquisition period defined in the current standard for a terminal whose CN eDRX period is greater than the system message update period.

For a terminal in the RRC deactivated state, when the network configures the terminal for the CN eDRX cycle and the RAN DRX cycle (If the RRC is configured with this parameter) when both are greater than the system message update period, the terminal uses the first eDRX acquisition period to acquire the updated system message.

也就是说,在实施例4中,对于RRC去激活态的UE,当网络给该UE配置的CN eDRX周期大于系统消息更新周期时,UE可以根据网络配置的RAN eDRX周期或RAN DRX周期来确定UE获取更新的系统消息的周期。That is, in Embodiment 4, for a UE in the RRC deactivated state, when the CN eDRX cycle configured by the network for the UE is greater than the system message update cycle, the UE can determine the RAN eDRX cycle or RAN DRX cycle configured by the network. The period at which the UE obtains updated system messages.
需要说明的是,在实施例4中,同时支持NAS配置CN eDRX和RRC配置RAN eDRX(比如,基站可配置的RAN寻呼周期最大值不超过10.24s的情况)。It should be noted that, in Embodiment 4, both CN eDRX configuration by NAS and RAN eDRX configuration by RRC are supported (for example, the case where the maximum RAN paging cycle configurable by the base station does not exceed 10.24s).
可选地,在本申请实施例中,系统消息更新周期可以根据上述公式3确定。即系统消息更新周期m=modificationPeriodCoeff*defaultPagingCycle,其中,modificationPeriodCoeff表示系统消息中指示的系统消息更新周期系数,defaultPagingCycle表示系统消息指示的小区默认寻呼周期。Optionally, in this embodiment of the present application, the system message update period may be determined according to the above formula 3. That is, the system message update cycle m=modificationPeriodCoeff*defaultPagingCycle, where modificationPeriodCoeff represents the system message update cycle coefficient indicated in the system message, and defaultPagingCycle represents the cell default paging cycle indicated by the system message.
可选地,在一些实施例中,该第一eDRX获取周期和/或该第二eDRX获取周期为预定义的值或者通过系统消息配置决定。Optionally, in some embodiments, the first eDRX acquisition period and/or the second eDRX acquisition period are predefined values or are determined through system message configuration.
需要说明的是,“去激活态”也可以称之为“非激活态”,本申请对此并不限定。It should be noted that the "deactivated state" may also be referred to as the "inactive state", which is not limited in the present application.
因此,在本申请实施例中,处于RRC去激活态的终端可以使用目标周期获取系统消息更新指示以及更新后的系统消息,以及网络设备可以使用目标周期向处于RRC去激活态的终端发送系统消息更新指示以及更新后的系统消息,从而优化系统消息的传输。进一步地,在本申请实施例中,既可以保证处于RRC去激活态且eDRX周期大于系统消息更新周期的终端设备尽可能及时地获取更新的系统消息,又可以很好地兼顾终端节能的需求。Therefore, in this embodiment of the present application, the terminal in the RRC deactivated state can use the target period to obtain the system message update indication and the updated system message, and the network device can use the target period to send the system message to the terminal in the RRC deactivated state Update indication and updated system messages, thereby optimizing the transmission of system messages. Further, in the embodiment of the present application, it can not only ensure that the terminal device in the RRC deactivated state and the eDRX period is longer than the system message update period can obtain the updated system information as soon as possible, but also can well take into account the demand for terminal energy saving.
