- DRX Terminal discontinuous reception
- R16 introduces a relaxation mechanism for neighbor cell measurement for non-connected UEs to further meet the needs of terminals for power saving.
- the low mobility (English: low mobility) criterion and the not-at-cell-edge (English: not-at-cell-edge) criterion are introduced. These two sets of criteria are measured by the measurement results of the UE on the serving cell.
- the definition of the low mobility criterion and the not-at-cell-edge criterion in the standard is as follows:
- the network will configure the reference signal received power (English: Reference Signal Received Power, abbreviated: RSRP) change evaluation duration TSearchDeltaP and RSRP change value threshold SSearchDeltaP.
- RSRP Reference Signal Received Power
- TSearchDeltaP RSRP change evaluation duration
- SSearchDeltaP RSRP change value threshold
- Srxlev is the current Srxlev measurement value of the serving cell
- SrxlevRef is the reference Srxlev value of the serving cell

- an RSRP threshold SSearchThresholdP When the RSRP of the UE on the serving cell is greater than the RSRP threshold, and the network is configured with Reference Signal Received Quality : RSRQ) threshold, when the RSRQ of the UE on the serving cell is greater than the RSRQ threshold, the UE is considered to meet the "not-at-cell-edge" criterion.
- the network notifies the UE whether the RRM measurement relaxation function can be enabled through a system broadcast.
- the network needs to configure at least one RRM measurement relaxation judgment criterion. For different configurations, the following four situations may exist:
- case1 The network only configures the low mobility criterion. At this time, when the UE meets the low mobility criterion, the UE starts relaxed RRM measurement for the neighboring cell.
- case2 The network only configures the not-at-cell-edge criterion, and when the UE satisfies the not-at-cell-edge criterion, the UE performs relaxed RRM measurement for neighboring cells.
- case3 The network configures the low mobility criterion and the not-at-cell-edge criterion at the same time, and the network does not configure the parameter combineRelaxedMeasCondition. At this time, when the UE meets at least one of the two criteria, the UE starts relaxed RRM for the neighboring cell Measurement.
- case4 The network configures the low mobility criterion and the not-at-cell-edge criterion at the same time, and the network configures the parameter combineRelaxedMeasCondition. At this time, when the UE meets these two criteria at the same time, the UE starts relaxed RRM measurement for the neighboring cell.
- TS38.133 defines the following two RRM measurement relaxation methods for unconnected UEs:
- Method 1 When the UE only meets the low mobility criterion or the not-at-cell-edge criterion, for intra-frequency measurement, NR inter-frequency measurement and inter-technology inter-frequency measurement, relax the measurement interval to 3 times the normal measurement interval.
- Method 2 When the UE meets both the low mobility criterion and the not-at-cell-edge criterion, the measurement interval can be relaxed to 1 hour for intra-frequency measurement, NR inter-frequency measurement and inter-technology inter-frequency measurement.
- highPriorityMeasRelax is introduced for high-priority frequency points, which is used to indicate whether the network allows the UE to relax the measurement interval of high-priority frequency points to exceed the Thigher_priority_search value (UE meets both the low mobility criterion and the not-at-cell -edge criterion except in the case).
- highPriorityMeasRelax is only used when the control network is only configured with the low mobility criterion and the UE meets the low mobility criterion, and the measurement result of the UE in the serving cell satisfies that Srxlev is greater than SnonIntraSearchP and Squal is greater than SnonIntraSearchQ.
- the UE's measurement interval for high priority frequency points can be relaxed to K2*Thigher_priority_search, where K2 is 60; otherwise (if the network does not have highPriorityMeasRelax), UE measures for high priority frequency points Points are measured at Thigher_priority_search interval.
- the static (English: stationary) criterion reuses the R16 low mobility criterion, and the network configures different thresholds (English: threshold) for these two criteria.
- the R17 stationary criterion is a mandatory configuration
- the R17 not cell edge criterion is an optional configuration
- the RRM measurement relaxation criteria mainly include the following three criteria:
- Low mobility criterion that is, Low mobility criterion
- Static criterion that is, Stationary criterion
- the RRM measurement relaxation criterion referred to in the embodiment of the present application is also at least one of the above three criteria.

- GEO Geostationary Earth Orbiting
- MEO Medium Earth Orbiting
- LEO Low Earth Orbiting
- GEO covers thousands of kilometers in diameter (Usually 3 satellites cover the whole world), relatively stationary to the ground, while MEO/LEO covers diameters ranging from tens of kilometers to thousands of kilometers depending on the orbital height, while ground cells usually cover hundreds of meters to thousands of kilometers in diameter meters, the coverage of satellite cells is much larger than that of ground cells.
- the non-GEO scenarios (such as LEO, MEO, etc.) in NTN include two scenarios: earth moving cell and quasi-earth fixed cell.
- earth moving cell means that the direction of the satellite beam remains unchanged, and the ground cell under satellite coverage moves with the movement of the satellite;
- the ground cell of the plot remains constant for a period of time.
- the network can broadcast a t-Service, which is used to indicate the time when the NTN cell stops serving the current coverage area.
- t-Service the definition of t-Service in the protocol is "Indicates the time information on when a cell provided via NTN quasi-Earth fixed system is going to stop serving the area it is currently covering.” This parameter will affect the UE's measurement behavior for neighboring cells. Specifically, if the network broadcasts t-Service, the UE must start RRM for neighboring cells before t-Service, regardless of whether the UE meets the conditions for starting neighboring cell measurement. Measurement.
- the network configures RRM measurement relaxation criteria for RRC disconnected state, then for UEs that meet RRM measurement relaxation, the UE can always perform relaxed RRM measurement for neighboring cells before t-Service or it needs to follow normal The measurement requires the execution of neighbor cell measurement, which has not been discussed in the current solution, and no specific processing solution has been given.
- this solution provides a solution of how to perform RRM measurement after receiving t-Service in RRC unconnected state and satisfying the RRM measurement relaxation criterion.

- Fig. 3 is the flow chart of Embodiment 1 of the method for determining the RRM measurement mode of a non-connected state terminal in the NTN of the embodiment of the present application. As shown in Fig. 3, the method specifically includes the following steps:
- S101 Configure measurement configuration information, where the measurement configuration information includes the time when the NTN cell stops serving the current coverage area.
- the network device can determine the time when the NTN cell stops serving the current coverage area according to the movement of the satellite.
- the time when the NTN cell stops serving the current coverage area refers to the time when the NTN cell leaves the current coverage area. That is t-Service (the meaning is: Indicates the time information on when a cell provided via NTN quasi-Earth fixed system is going to stop serving the area it is currently covering).
- S102 Broadcast measurement configuration information.
- the network device After the network device determines the time when the NTN cell stops serving the current coverage area, it broadcasts the time when the NTN cell stops serving the current coverage area through the system broadcast, that is, all terminal devices within the coverage area of the NTN cell can receive the network The measurement configuration information broadcast by the device.
- S103 Receive measurement configuration information broadcast by the network device, where the measurement configuration information includes the time when the NTN cell stops serving the current coverage area.
- the terminal device receives the system broadcast message and receives the NTN cell broadcast by the network device to stop serving the current coverage area time (t-Service). Based on the t-Service, the terminal device can determine that the currently serving NTN cell will stop serving after t-Service, so for the terminal device, it is necessary to measure the neighboring cells before the current NTN cell stops serving the current coverage area, so that After the current NTN cell stops serving, it can access other cells to avoid wireless network interruption.
- t-Service current coverage area time
- the RRM measurement manner at least includes RRM normal measurement or RRM relaxation measurement.
- the terminal device does not satisfy the RRM measurement relaxation criterion, it only needs to perform normal measurement on the neighboring cells directly. However, if the terminal device meets the RRM measurement relaxation criterion, it needs to determine whether to perform normal measurement or RRM relaxation measurement on the neighbor cell before the time when the NTN cell stops serving the current coverage area according to the measurement configuration information configured by the network device.
- the first implementation mode for a terminal device in the RRC disconnected state, as long as the network device broadcasts and the terminal device receives the t-Service, no matter whether the terminal meets the RRM measurement relaxation criteria, the neighbor cell will be measured before the t-Service according to the Normal measurement requires RRM measurement, that is, normal RRM measurement is performed before t-Service.
- the network device also configures another RRM measurement relaxation indication information (that is, the Allowed-RRM-relax indication information), which is used to indicate whether to allow a terminal device that meets the RRM measurement relaxation criterion to stop serving the current coverage in the NTN cell RRM relaxation measurements are performed for neighboring cells before the time of the region.
- another RRM measurement relaxation indication information that is, the Allowed-RRM-relax indication information
- RRM relaxation measure For a terminal device that is in the RRC disconnected state and meets the RRM measurement relaxation criterion, it needs to determine whether to use RRM normal measurement or RRM measurement for the neighboring cell before the time when the NTN cell stops serving the current coverage area according to the RRM measurement relaxation indication information.
- RRM relaxation measure For a terminal device that is in the RRC disconnected state and meets the RRM measurement relaxation criterion, it needs to determine whether to use RRM normal measurement or RRM measurement for the neighboring cell before the time when the NTN cell stops serving the current coverage area according to the RRM measurement relaxation indication information.
- the terminal device stops serving the current coverage area in the NTN cell.
- the terminal equipment needs to restore the adjacent cell to perform RRM normal measurement before the time when the NTN cell stops serving the current coverage area, that is, perform RRM measurement according to the normal measurement requirements.
- the terminal device may perform RRM measurement on neighboring cells according to the determined manner.
- the RRM measurement relaxation criterion may include at least one criterion among the low mobility criterion, the static criterion and the not-in-cell-center criterion, and this solution is not limited thereto.
- the method for determining the RRM measurement method of a non-connected terminal in NTN provides an RRC non-connected terminal device, how to perform RRM measurement on a neighboring cell after receiving the time when the NTN cell stops serving the current coverage area solution, the terminal device can measure neighboring cells according to the above-mentioned solution, determine a suitable candidate neighboring cell as soon as possible, and can access a suitable candidate neighboring cell after the currently serving NTN cell stops serving.
- the network device broadcasts the time when the NTN cell stops serving the current coverage area, Then no matter whether the terminal device meets the RRM measurement relaxation criterion, it must perform RRM measurement for the neighboring cell according to the normal measurement requirements before the time when the NTN cell stops serving the current coverage area (that is, the terminal device does not perform relaxed RRM measurement for the neighboring cell ).
- the execution process of the terminal device is as follows:
- the terminal device in the NTN cell receives the time (t-Service) at which the NTN cell stops serving the current coverage area broadcast by the network device.
- the terminal device For a terminal device in the RRC non-connected state, if the network device broadcasts a t-Service, no matter whether the terminal device meets the RRM measurement relaxation criteria, it must perform normal measurement requirements for neighboring cells before the t-Service RRM measurement. That is, for a terminal device that does not meet the RRM measurement relaxation criteria, it is enough to continue to perform RRM measurement for the neighboring cell according to the normal measurement requirements before the t-Service. For a terminal device that satisfies the RRM measurement relaxation criterion, the terminal device shall return to perform RRM measurement for the neighboring cell according to the normal measurement requirement before the t-Service.
- FIG. 4 is a schematic diagram of RRM measurement of a terminal device that satisfies the RRM measurement relaxation criterion provided in an embodiment of the present application.
- the terminal device that satisfies the RRM measurement relaxation criterion has been performing relaxed RRM measurement before T0, And when T0 receives the time t-Service when the NTN cell stops serving the current coverage area, the terminal device needs to resume performing RRM measurement on neighboring cells according to the normal measurement requirements during the period between T0 and t-Service.
- the specific time point at which the terminal device recovers to perform RRM measurement according to the normal measurement requirements for the neighboring cells may depend on the implementation of the terminal device.

Description
本申请实施例涉及卫星通信技术,尤其涉及一种NTN中非连接态终端的RRM测量方式确定方法、装置及介质。
目前第三代合作伙伴计划(3rd Generation Partnership Project,简称:3GPP)正在研究非地面通信网络(Non Terrestrial Network,简称:NTN)技术,NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信,卫星通信具有很多独特的优点。首先,卫星通信不受用户地域的限制,例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域,而对于卫星通信来说,由于一颗卫星即可以覆盖较大的地面,加之卫星可以围绕地球做轨道运动,因此理论上地球上每一个角落都可以被卫星通信覆盖。
对于NTN中的非地球同步轨道(Geostationary Earth Orbit,简称:GEO)场景(如低地球轨道(Low-Earth Orbit,简称:LEO),中地球轨道(Medium-Earth Orbit,简称:MEO)等),包括earth moving cell和quasi-earth fixed cell两种场景。earth moving cell指的是卫星波束方向不变,卫星覆盖下的地面小区随着卫星的运动而移动;quasi-earth fixed cell指的是在卫星运动的过程中,通过调整卫星波束方向使得卫星覆盖下的地面小区在一段时间内保持不变。
基于目前无线接入网(Random Access Network,简称:RAN)2会议结论,对于quasi-earth fixed cell场景,网络可以广播一个t-Service,该参数用于指示NTN小区停止服务当前覆盖区域的时间。该参数会影响UE针对邻小区的测量行为,具体体现在,如果网络广播了t-Service,则不论UE是否满足启动邻区测量的条件,UE都要在t-Service之前启动针对邻区的无线资源管理(Radio Resource Management,简称:RRM)测量。
然而,在上述场景中,如果网络配置了针对RRC非连接态的RRM测量放松准则,那么对于满足RRM测量放松准则的UE,UE在t-Service之前针对邻小区的测量如何执行,现有技术中还没有相关的技术方案。

在5G常见的应用场景中,增强移动超宽带(Enhanced Mobile Broadband,简称:eMBB)仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。低时延高可靠通信(Ultra Reliable Low Latency Communications,简称:URLLC)的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。大规模机器类通信(massive Machine Type Communications,简称:mMTC)的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
5G网络环境中为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC_INACTIVE状态。这种状态有别于RRC_IDLE和RRC_CONNECTED状态。下面以用户设备(User Equipment,简称:UE)为用户侧设备以及基站为网络设备为例,对这几个状态进行介绍:
空闲态(RRC_IDLE):移动性为基于UE的小区选择重选,寻呼由CN发起,寻呼区 域由CN配置。基站侧不存在UE AS上下文。不存在RRC连接。
连接态(RRC_CONNECTED):存在RRC连接,基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
非激活态(RRC_INACTIVE):移动性为基于UE的小区选择重选,存在CN-NG-RAN之间的连接,UE AS上下文存在某个基站上,寻呼由无线接入网(Radio Access Network,简称:RAN)触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。
R15NR中关于非连接态UE的无线资源管理(Radio Resource Management,简称:RRM)测量测量:
处于非连接态的UE需要基于网络的配置对服务小区以及其他邻小区进行RRM测量以支持移动性操作,例如小区重选等。
非连接态的UE针对服务小区测量是持续进行的。
在NR Rel-15中,出于UE节能的考虑,当UE在服务小区的质量信道较好时,UE可以不启动针对同频频点以及同等优先级或低优先级的异频/异技术频点的RRM测量,对于优先级异频/异技术频点可以执行放松的RRM测量。具体而言:
对于同频频点,如果服务小区测量的Srxlev高于SIntraSearchP且Squal SIntraSearchQ,则UE可以关闭所有同频邻小区的测量。
对于低优先级或者同等优先级的NR异频频点或异技术频点,如果服务小区测量的Srxlev高于SnonIntraSearchP且Squal高于SnonIntraSearchQ,则UE可以关闭所有低优先级或者同等优先级的NR异频频点或异技术频点的测量。
对于高优先级的NR异频频点或异技术频点,如果服务小区测量的Srxlev高于SnonIntraSearchP且Squal高于SnonIntraSearchQ,则UE可以针对高优先级的NR异频频点或异技术频点执行放松的测量,此时对于每个高优先级频点,测量间隔放松为Thigher_priority_search=(60*Nlayers)s,其中Nlayers为网络广播的高优先级频点的个数。
其中,参数SIntraSearchP,SIntraSearchQ,SnonIntraSearchP和SnonIntraSearchQ由网络通过SIB2进行配置。
新无线(New Radio,简称:NR)中,小区测量requirement包括Tdetect,Tmeasure和Tevaluate,分别针对于小区检测,小区测量和小区评估所用的时间,通常这些requirement和终端的非连续接收(Discontinuous Reception,简称:DRX)周期相关。
R16NR中关于非连接态UE的RRM测量放松的内容:
R16引入了针对非连接态UE的邻小区测量放松机制,以进一步满足终端省电的需求。
为了支持放松的邻小区测量,引入了低移动性(英文:low mobility)准则和不在小区中心(英文:not-at-cell-edge)准则。这两套准则都是以UE在服务小区上的测量结果来进行衡量的。标准中针对low mobility准则和not-at-cell-edge准则的定义如下:
“low mobility”准则
针对该准则,网络会配置参考信号接收功率(英文:Reference Signal Received Power,简称:RSRP)变化的评估时长TSearchDeltaP和RSRP变化值门限SSearchDeltaP。当一段时间TSearchDeltaP内UE在服务小区上的RSRP变化量小于SSearchDeltaP时,则认为该UE满足“low mobility”准则。即:在一段时间TSearchDeltaP内,满足:
(SrxlevRef–Srxlev)<SSearchDeltaP公式<1>
其中:Srxlev是服务小区的当前Srxlev测量值,SrxlevRef是服务小区的参考Srxlev值。
当UE选择或重选到一个新的小区;或者,
如果(Srxlev-SrxlevRef)>0;或者,
如果UE没有在持续TSearchDeltaP时间内满足公式<1>:UE将SrxlevRef设为服务小区的当前Srxlev测量值;
UE在完成小区选择/重选之后,需要在至少一段时间TSearchDeltaP内执行正常的RRM测量。
“not-at-cell-edge”准则
针对该准则,网络会配置一个RSRP门限SSearchThresholdP,另外还可以配置一个RSRQ门限SSearchThresholdQ,当UE在服务小区上的RSRP大于该RSRP门限,并且在网络配置了参考信号接收质量(Reference Signal Received Quality,简称:RSRQ)门限的情况下,UE在服务小区上的RSRQ大于该RSRQ门限时,则认为该UE满足“not-at-cell-edge”准则。
网络通过***广播的方式通知UE是否可以启动RRM测量放松的功能。在启动RRM测量放松功能的情况下,网络需要至少配置一个RRM测量放松判断准则。针对不同的配置,可能存在以下四种情况:
case1:网络只配置了low mobility准则,此时当UE满足low mobility准则时,UE针对邻小区启动放松的RRM测量。
case2:网络只配置了not-at-cell-edge准则,则当UE满足not-at-cell-edge准则时,UE针对邻小区执行放松的RRM测量。
case3:网络同时配置了low mobility准则和not-at-cell-edge准则,并且网络没有配置参数combineRelaxedMeasCondition,此时当UE满足这2个准则中的至少一个准则时,UE针对邻小区启动放松的RRM测量。
case4:网络同时配置了low mobility准则和not-at-cell-edge准则,并且网络配置了参数combineRelaxedMeasCondition,此时当UE同时满足这2个准则时,UE针对邻小区启动放松的RRM测量。
除此之外,TS38.133中针对非连接态UE定义了以下两种RRM测量放松方法:
方法1:当UE只满足low mobility准则或not-at-cell-edge准则时,对于同频测量,NR异频测量和异技术异频测量,将测量间隔放松至正常测量间隔的3倍。
方法2:当UE同时满足low mobility准则和not-at-cell-edge准则时,对于同频测量,NR异频测量和异技术异频测量,测量间隔可以放松至1小时。
此外,针对高优先级频点,引入了highPriorityMeasRelax,该参数用于指示网络是否允许UE在高优先级频点的测量间隔放松到超过的Thigher_priority_search值(UE同时满足low mobility准则和not-at-cell-edge准则的情况除外)。换句话说,highPriorityMeasRelax只用于控制网络只配置了low mobility准则并且UE满足low mobility准则,且UE在服务小区的测量结果满足Srxlev大于SnonIntraSearchP并且Squal大于SnonIntraSearchQ的情况。在这种情况下,如果网络配置了highPriorityMeasRelax,则UE针对高优先级频点的测量间隔可以放松至K2*Thigher_priority_search,其中,K2为60;否则(如果网络没有highPriorityMeasRelax),UE针对高优先级频点的测量间隔为Thigher_priority_search。
在R16 low mobility和not cell edge准则基础上,R17进一步研究了针对静止终端的RRM测量放松,当前标准讨论已形成以下明确结论:
1.R17中,静止(英文:stationary)准则重用R16 low mobility准则,网络针对这2个准则配置不同的阈值(英文:threshold)。
2.如果网络要配置针对R17非连接态UE的RRM放松准则,R17 stationary准则为必选配置,R17的not cell edge准则为可选配置。
综上所述,在目前的NR标准中,RRM测量放松准则主要包括以下三个准则:
低移动性准则,即Low mobility准则;
静止准则,即Stationary准则;
不在小区中心准则,即Not-at-cell-edge准则。
在本申请实施例中所指的RRM测量放松准则也是上述这三种准则中的至少一种。
随着对无线网络技术需求的逐渐增加,3GPP正在研究非地面通信网络(Non Terrestrial Network,简称:NTN)技术,NTN一般采用卫星通信的方式向地面用户提供通信服务。卫星可以分为地球同步轨道(Geostationary Earth Orbiting,简称:GEO)/中轨道(Medium Earth Orbiting,简称:MEO)/低轨道(Low Earth Orbiting,简称:LEO),GEO覆盖直径可达数千公里(通常3颗卫星覆盖全球),相对地面静止,而MEO/LEO又根据轨道高度的不同,覆盖直径从几十公里到上千公里不等,而地面小区通常覆盖直径也就几百米到上千米,卫星小区的覆盖远大于地面小区。
目前的技术方案中,对NTN中的非GEO场景(如LEO,MEO等),包括earth moving cell和quasi-earth fixed cell两种场景。earth moving cell指的是卫星波束方向不变,卫星覆盖下的地面小区随着卫星的运动而移动;quasi-earth fixed cell指的是在卫星运动的过程中,通过调整卫星波束方向使得卫星覆盖下的地面小区在一段时间内保持不变。
基于目前RAN2会议结论,对于quasi-earth fixed cell场景,网络可以广播一个t-Service,该参数用于指示NTN小区停止服务当前覆盖区域的时间,具体的,在协议中对于t-Service的定义为“Indicates the time information on when a cell provided via NTN quasi-Earth fixed system is going to stop serving the area it is currently covering.”。该参数会影响UE针对邻小区的测量行为,具体体现在,如果网络广播了t-Service,则不论UE是否满足启动邻区测量的条件,UE都要在t-Service之前启动针对邻区的RRM测量。然而,如果网络配置了针对RRC非连接态的RRM测量放松准则,那么对于满足RRM测量放松的UE,UE在t-Service之前针对邻小区的测量是可以一直执行放松的RRM测量还是需要按照正常的测量要求执行邻区测量,目前的方案中还未讨论到,也没有给出具体的处理方案。
针对上述问题,本方案提供一种RRC非连接态、满足RRM测量放松准则的UE在接收到t-Service之后,如何进行RRM测量的方案。该方案可以应用在各种类型的卫星网络架构中。
图1为本申请实施例提供的透明转发的卫星网络架构示意图,如图1所示,在该透明转发的卫星网络架构中,需要单独设置基站,网络通过基站,卫星与UE之间的交互进行数据的转发交互。卫星和地面站组成远程无线单元(英文:Remote Radio Unit)。
图2为本申请实施例提供的再生转发的卫星网络架构示意图,如图2所示,在该再生转发的卫星网络架构中,不需要单独设置基站,网络通过设置在卫星内部的基站功能与UE之间的交互进行数据的转发交互。
在上述两种架构中,其中,卫星和地面站(NTN gateway,通常位于地面)之间的无线链路可以称为feeder link。
在上述卫星网络架构的基础上,应理解,本申请的技术方案主要应用在网络设备和终端设备两个执行主体中。网络设备进行测量相关的配置,终端设备根据网络设备的配置确定如何进行测量。该网络设备可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。在本申请的场景中,该网络设备为提供卫星服务的基站,可以是单独设置的基站也可以是设置在卫星中的基站,对此本方案不做限制。
终端设备包括但不限于经由数据连接/网络和/或经由无线接口进行通信的装置,如,针对蜂窝网络、无线局域网(Wireless Local Area Network,WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器;和/或另一被设置成接收/发送通信信号的装置;和/或物联网(Internet of Things,IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话;可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个 人通信***(Personal Communications System,PCS)终端;可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位***(Global Positioning System,GPS)接收器的PDA;以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备,卫星网络中的终端设备或者未来演进的PLMN中的终端设备等,对此本方案不做限制。
下面通过几个具体实施例对本申请提供的NTN中非连接态终端的RRM测量方式确定方法进行详细描述。
图3为本申请实施例NTN中非连接态终端的RRM测量方式确定方法实施例一的流程图,如图3所示,该方法具体包括以下步骤:
S101:配置测量配置信息,测量配置信息包括NTN小区停止服务当前覆盖区域的时间。
在本步骤中,对于网络设备来说,随着卫星的移动,当前正在为某些终端设备服务的NTN小区可能在一段时间之后离开当前覆盖区域,即不能继续为当前覆盖区域的设备提供信号覆盖,此时网络设备可以根据卫星的移动情况确定出NTN小区停止服务当前覆盖区域的时间。该NTN小区停止服务当前覆盖区域的时间指的是所述NTN小区离开当前覆盖区域时的时间。也就是t-Service(其含义为:Indicates the time information on when a cell provided via NTN quasi-Earth fixed system is going to stop serving the area it is currently covering)。
S102:广播测量配置信息。
网络设备在确定出NTN小区停止服务当前覆盖区域的时间之后,通过***广播将该NTN小区停止服务当前覆盖区域的时间进行广播,即在该NTN小区覆盖范围内的所有终端设备都可以接收到网络设备广播的该测量配置信息。
S103:接收网络设备广播的测量配置信息,测量配置信息包括NTN小区停止服务当前覆盖区域的时间。
在本步骤中,以任一个终端设备为例,该终端设备通过接收***广播消息,接收到网络设备广播的NTN小区停止服务当前覆盖区域时间(t-Service)。基于该t-Service,终端设备能够确定当前服务的NTN小区在t-Service之后将停止服务,因此对于终端设备来说,则需要在当前NTN小区停止服务当前覆盖区域之前针对邻小区进行测量,以便在当前NTN小区停止服务之后能够接入别的小区,避免无线网络中断。
S104:若终端设备满足RRM测量放松准则,则根据测量配置信息确定在NTN小区停止服务当前覆盖区域的时间之前对邻小区的RRM测量方式。
在本申请的技术方案中,RRM测量方式至少包括RRM正常测量或者RRM放松测量。
在本步骤中,当处于无线资源控制(Radio Resource Control,简称:RRC)非连接态的终端设备预先配置了RRM测量放松准则,则在接收到网络设备广播的测量配置信息之后,确定是否满足RRM测量放松准则。
如果该终端设备不满足RRM测量放松准则,那么直接对邻小区进行正常测量即可。然而,如果该终端设备满足RRM测量放松准则,则需要根据网络设备配置的测量配置信息,确定在NTN小区停止服务当前覆盖区域的时间之前对邻小区进行正常测量还是RRM放松测量。
在本步骤的具体实现中,本申请提供了下面几种实现方式:
第一种实现方式,对于处于RRC非连接态的终端设备,只要网络设备广播且终端设备接收到了t-Service,则无论该终端是否满足RRM测量放松准则,均在t-Service之前对邻小区按照正常的测量要求进行RRM测量,即在t-Service之前进行正常RRM测量。
第二种实现方式,网络设备还配置另外一个RRM测量放松指示信息(即Allowed-RRM-relax指示信息),用来指示是否允许满足RRM测量放松准则的终端设备在所述NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量。
对于处于RRC非连接态的终端设备,且满足RRM测量放松准则的终端被,则需要根据该RRM测量放松指示信息来确定在NTN小区停止服务当前覆盖区域的时间之前对邻小区采用RRM正常测量或者RRM放松测量。
具体实现中,如果RRM测量放松指示信息指示允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量,那么该终端设备在NTN小区停止服务当前覆盖区域的时间之前可以继续对邻小区进行RRM放松测量;否则,如果RRM测量放松指示信息指示不允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量,那么该终端设备在NTN小区停止服务当前覆盖区域的时间之前需要恢复邻小区进行RRM正常测量,即按照正常测量要求执行RRM测量。
进一步的,终端设备在确定了测量方式之后,可以根据确定出的方式对邻小区进行RRM测量。
应理解,在本申请的所有实施例中,RRM测量放松准则可以包括低移动性准则、静止准则和不在小区中心准则中的至少一个准则,对此本方案不做限制。
本实施例提供的NTN中非连接态终端的RRM测量方式确定方法,提供了一种RRC非连接态终端设备,在接收到NTN小区停止服务当前覆盖区域时间之后,如何对邻小区进行RRM测量的方案,终端设备可按照上述方案对邻小区进行测量,尽快确定出合适的候选邻小区,在当前服务的NTN小区停止服务之后能够接入合适的候选邻小区。
基于上述实施例的基础,在本申请提供的NTN中非连接态终端的RRM测量方式确定方法的一种具体实现中,对于NTN小区,如果网络设备广播了NTN小区停止服务当前覆盖区域的时间,则无论终端设备是否满足RRM测量放松准则,都在该NTN小区停止服务当前覆盖区域的时间之前都要针对邻小区按照正常的测量要求执行RRM测量(即终端设备针对邻小区不执行放松的RRM测量)。
终端设备的执行过程具体如下:
1,处于NTN小区中的终端设备接收到网络设备广播的NTN小区停止服务当前覆盖区域的时间(t-Service)。
2,对于处于RRC非连接态的终端设备,如果网络设备广播了t-Service,则无论该终端设备是否满足RRM测量放松准则,在该t-Service之前都要针对邻小区按照正常的测量要求执行RRM测量。即:对于不满足RRM测量放松准则的终端设备,在t-Service之前针对邻小区继续按照正常的测量要求执行RRM测量即可。对于满足RRM测量放松准则的终端设备,该终端设备要在t-Service之前针对邻小区恢复到按照正常的测量要求执行RRM测量。
图4为本申请实施例提供的一种满足RRM测量放松准则的终端设备的RRM测量示意图,如图4所示,满足RRM测量放松准则的终端设备在T0之前,一直在执行放松的RRM测量,且在T0时接收到了NTN小区停止服务当前覆盖区域时间t-Service,则该终端设备在T0至t-Service之间这段时间需要恢复对邻小区按照正常测量要求执行RRM测量。
在具体的实现中,终端设备针对邻小区恢复到按照正常的测量要求执行RRM测量的具体时间点可以取决于终端设备的实现。
本实施例提供的方案中,如果网络设备广播了t-Service,则无论终端设备是否满足RRM测量放松准则,在所述t-Service之前都要针对邻小区按照正常的测量要求执行RRM测量。使用该方法,可以使得终端设备在当前NTN小区停止提供服务之前,通过邻区测量尽快找到合适的候选邻区,从而缩短了在当前小区离开后终端设备重选到其他小区的时间,能够更好的满足终端移动性管理的需求。
图5为本申请实施例NTN中非连接态终端的RRM测量方式确定方法一实例的流程图,如图5所示,在上述实施例一的基础上,本实施例提供另一种实现方案,对于NTN小区,如果网络设备广播了小区停止服务当前覆盖区域的时间,则对于满足RRM测量放松准则的终端设备,基于网络设备的其他配置确定是否在当前NTN小区停止服务当前覆盖区域的时间之前要针对邻小区恢复到按照正常的测量要求执行RRM测量(即针对邻小区不执行放松的RRM测量)。具体的,该方案包括以下步骤:
S201:网络设备配置NTN小区停止服务当前覆盖区域的时间。
S202:网络设备配置RRM测量放松指示信息。
在前述两个步骤中,网络设备不止配置了NTN小区停止服务当前覆盖区域的时间,还配置了指示是否允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量的RRM测量放松指示信息。
也就是说网络设备配置的测量配置信息包括NTN小区停止服务当前覆盖区域的时间以及RRM测量放松指示信息。网络设备通过***广播将该测量配置信息广播给终端设备。
在该方案的一种具体实现中,网络设备可以同时配置配置NTN小区停止服务当前覆盖区域的时间和RRM测量放松指示信息,通过测量配置信息同时广播给终端设备。网络设备也可以在配置了NTN小区停止服务当前覆盖区域的时间之后,再配置RRM测量放松指示信息,然后通过一次***广播将NTN小区停止服务当前覆盖区域的时间和RRM测量放松指示信息广播给终端设备,也可以分别通过不同的***广播将NTN小区停止服务当前覆盖区域的时间和RRM测量放松指示信息广播给终端设备,对此本方案不做限制。
在该方案的具体实现中,应理解,网络设备只有在配置NTN小区停止服务当前覆盖区域的时间的前提下,才可以配置RRM测量放松指示信息。
S203:RRM测量放松指示信息指示是否允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量。
在本步骤中,对于终端设备来说,在接收到了网络设备广播的NTN小区停止服务当前覆盖区域的时间和RRM测量放松指示信息之后,则对于处于RRC非连接态的终端设备,如果网络设备广播了NTN小区停止服务当前覆盖区域的时间t-Service,并且该终端设备满足RRM测量放松准则,则该终端设备基于网络配置的RRM测量放松指示信息(Allowed-RRM-relax指示信息)确定是否在该t-Service之前针对邻小区恢复到按照正常的测量要求执行RRM测量。
S204:若RRM测量放松指示信息指示允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量,则在NTN小区停止服务当前覆盖区域的时间之前对邻小区采用RRM放松测量。
S205:若RRM测量放松指示信息指示不允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量,则在NTN小区停止服务当前覆盖区域的时间之前对邻小区采用正常RRM测量。
在上述两个步骤中,可知,如果Allowed-RRM-relax指示信息指示不允许满足RRM测量放松准则的终端设备在t-Service之前可以针对邻小区一直执行放松的RRM测量,则:对于满足RRM测量放松准则的终端设备,该终端设备需要在t-Service之前针对邻小区恢复到按照正常的测量要求执行RRM测量,即采用正常RRM测量。
如果Allowed-RRM-relax指示信息指示允许满足RRM测量放松准则的UE在t-Service 之前可以针对邻小区一直执行放松的RRM测量,则:对于满足RRM测量放松准则的终端设备,该终端设备可以针对邻小区执行放松的RRM测量(即RRM测量放松的行为只取决于终端设备是否满足RRM测量放松准则,不会受到t-Service的影响)。
与前述实施例类似的,终端设备针对邻小区恢复到按照正常的测量要求执行RRM测量的时间点可以取决于终端设备的具体实现,本方案中不做具体限定。
在本实施例的一种具体实现中,网络设备对于Allowed-RRM-relax指示信息的配置,可以具体实现为以下几种情况:
第一种情况:网络设备将Allowed-RRM-relax指示信息配置为不同的指示值。如:Allowed-RRM-relax指示信息配置为第一指示值指示允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量,Allowed-RRM-relax指示信息配置为第二指示值指示不允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量。具体的,可以配置为RRM测量放松指示信息为1时,指示允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域时间之前针对邻小区执行RRM放松测量。RRM测量放松指示信息为0时,指示不允许满足RRM测量放松准则的终端设备在所述NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量。
可选的,通过RRM测量放松指示信息为0指示允许,RRM测量放松指示信息为1指示不允许也可以实现,对此本方案不做限制。
第二种情况,网络设备可以通过是否具体配置Allowed-RRM-relax指示信息来实现是否允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量的指示。具体的,若网络配置了RRM测量放松指示信息,则指示允许满足RRM测量放松准则的终端设备在所述NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量;若网络未配置RRM测量放松指示信息,则指示不允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前针对邻小区执行RRM放松测量。
其含义是,网络设备如果没有配置RRM测量放松指示信息的具体内容,则意味着不允许满足RRM测量放松准则的终端设备在NTN小区停止服务当前覆盖区域的时间之前继续对邻小区执行RRM放松测量,需要恢复正常RRM测量。
本申请实施例提供的NTN中非连接态终端的RRM测量方式确定方法,在网络设备配置了针对RRC非连接态的RRM测量放松准则,那么对于满足RRM测量放松的终端设备,在t-Service之前针对邻小区的测量是可以一直执行放松的RRM测量还是需要按照正常的测量要求执行邻区测量,提供了几种具体实现方案,通过这些方案,对邻小区进行RRM测量,在当前NTN小区停止服务之后尽快找到合适的候选邻小区,继续为终端设备提供网络服务。
