| On the other hand, since the light connected state is assumed to perform a mobility control in the predetermined area units including a plurality of cells, it is considered that measurement in cell units is not necessarily appropriate. |
另一方面，由于假设光连接状态在包括多个单元的预定区域单元中执行移动性控制，所以认为单元单元中的测量不一定是适当的。 |
| Therefore, the UE 100 in the light connected state performs the RLM measurement in the predetermined area units. |
因此，处于光连接状态的用户设备100以预定的面积单位执行RLM 测量。 |
| [0110] |
[0110] |
| For example, if a problem is detected in all the cells detected in the predetermined area, the UE 100 in the light connected state may determine the RLF in the RLM measurement. |
例如，如果在预定区域中检测到的所有小区中检测到问题，则处于轻连接状态的用户设备100可以在RLM 测量中确定RLF 。 |
| In other words, even if a problem occurs in one cell in a predetermined area, it is not necessary to determine as the RLF if no problem occurs in another cell in the predetermined area. |
换句话说，即使在预定区域中的一个小区中发生问题，如果在预定区域中的另一小区中没有发生问题，也不必将其确定为RLF 。 |
| For example, when the UE 100 returns to the RRC connected state, the UE 100 may report the result of the RLM measurement (for example, that there was the RLF) to the network. |
例如，当用户设备（UE ）100返回至无线资源控制（RRC ）连接状态时，用户设备（UE ）100可以将无线资源控制（RLM ）测量结果（例如，存在无线资源控制（RLF ））报告给网络。 |
| The result of the RLM measurement may include an identifier of the predetermined area. |
RLM 测量的结果可以包括预定区域的标识符。 |

第四实施例 |
| [0111] |
[0111] |
| In a fourth embodiment, a difference from the first to third embodiments will be mainly described below. |
在第四实施例中，下面将主要描述第一到第三实施例的区别。 |
| [0112] |
[0112] |
| The UE 100 according to the fourth embodiment receives, from the network, information indicating the radio resource pool for uplink transmission. |
根据第四实施例的用户设备100从网络接收指示用于上行链路传输的无线资源池的信息。 |
| If the UE 100 is in the light connected state, the UE 100 (autonomously) selects the radio resource from the radio resource pool and performs uplink transmission by using the selected radio resource. |
如果用户设备（UE ）100处于轻连接状态，则用户设备（UE ）100（自主地）从无线资源池中选择无线资源，并且通过使用所选择的无线资源来执行上行链路传输。 |
| Such an uplink transmission may be performed on a contention basis. |
这样的上行链路传输可以基于竞争来执行。 |
| [0113] |
[0113] |
| FIG. 10 is a diagram illustrating an operation according to the fourth embodiment. |
图10是示出根据第四实施例的操作的图。 |
| In the initial state, the UE 100 has the RRC connection with the eNB 200 and is in the RRC connected state. |
在初始状态下，用户终端100与eNB200建立RRC 连接，并处于RRC 连接状态。 |
| [0114] |
[0114] |
| As illustrated in FIG. 10, in step S401, the eNB 200 transitions the UE 100 to the light connected state. |
如图10所示，在步骤S401中，eNB200将用户设备100转换为光连接状态。 |
| For example, the eNB 200 transmits, to the UE 100, the instruction (configuration) to transition to the light connected state by using the UE dedicated RRC signaling. |
例如，eNB200通过使用UE 专用RRC 信令向用户设备100发送转换到轻连接状态的指令（配置）。 |
| [0115] |
[0115] |
| In step S402, the UE 100 transitions from the RRC connected state to the light connected state. |
在步骤S402，用户设备100从无线资源控制连接状态转换到光连接状态。 |
| [0116] |
[0116] |
| In step S403, the eNB 200 transmits information indicating the radio resource pool for uplink transmission. |
在步骤S403中，eNB200发送指示用于上行链路传输的无线资源池的信息。 |
| The eNB 200 may transmit the pool information by broadcast signaling (for example, SIB). |

| The pool information includes a radio resource area (frequency and time information) in which the UE 100 in the light connected state may perform uplink transmission. |
该池信息包括无线资源区域（频率和时间信息），在该无线资源区域中处于轻连接状态的用户设备100可以执行上行链路传输。 |
| [0117] |
[0117] |
| Alternatively, the eNB 200 may transmit the pool information by UE dedicated signaling when the UE 100 transitions to the light connection. |
或者，eNB200可以在用户设备100转换到光连接时，通过用户设备专用信令发送池信息。 |
| In this case, in step S401, the eNB 200 may include the pool information as the instruction to transition to the light connected state. |
在这种情况下，在步骤S401中，eNB200可以包括池信息作为转换到光连接状态的指令。 |
| [0118] |
[0118] |
| The pool information may include parameters (for example, parameters for hopping in units of resource elements) for distributing the radio resources on which the uplink transmission is actually performed on the frequency axis and/or the time axis among radio resource pools for uplink transmission. |
该池信息可以包括用于在用于上行链路传输的无线电资源池中分布在频率轴和/或时间轴上实际执行上行链路传输的无线电资源的参数（例如，用于以资源元素为单位跳跃的参数）。 |
| The parameter is an offset indicating a start position of a resource element on which the uplink transmission is actually performed, an interval of distribution (hopping), and the like. |
该参数是指示在其上实际执行上行链路传输的资源元素的开始位置，分布间隔（跳跃）等的偏移。 |
| Specifically, parameters such as offsetting from the edge of a certain radio resource area by 3 resource elements and distributing at 4 resource element intervals are designated. |
具体地，指定诸如从某个无线电资源区域的边缘偏移3个资源元素以及以4个资源元素间隔分布的参数。 |
| [0119] |
[0119] |
| In step S404, the UE 100 in the light connected state selects the radio resource from the radio resource pool based on the pool information from the eNB 200. |
在步骤S404中，处于轻连接状态的用户设备100基于来自eNB200的池信息从无线资源池中选择无线资源。 |
| The UE 100 may select the radio resource by applying an identifier such as an international mobile subscriber identity (IMSI) to a predetermined selection rule. |
用户设备（UE ）100可以通过将诸如国际移动用户标识（IMSI ）的标识符应用于预定选择规则来选择无线资源。 |
| For example, the UE 100 calculates an offset start point by “IMSI mod N”. |
例如，用户设备（UE ）100利用“IMSImodN ”来计算偏移开始点。 |
| Here, N is a fixed value and may be, for example, 100. |
这里，N 是固定值，例如可以是100。 |
| [0120] |
[0120] |
| In step S405, the UE 100 performs uplink transmission by using the selected radio resource. |
在步骤S405中，用户设备100通过使用所选择的无线资源来执行上行链路传输。 |
| Fifth Embodiment |
第五实施方案 |
| [0121] |
[0121] |
| In a fifth embodiment, a difference from the first to fourth embodiments will be mainly described below. |
在第五实施例中，下面将主要描述第一至第四实施例的区别。 |
| [0122] |
[0122] |
| The UE 100 according to the fifth embodiment performs cell reselection of reselecting a target cell used as a serving cell if the UE 100 is in the light connected state. |
根据第五实施例的用户设备（UE ）100执行小区重选，如果用户设备（UE ）100处于轻连接状态，则重选用作服务小区的目标小区。 |
| The cell reselection includes a redistribution procedure for allocating the target cell selected as the serving cell. |
小区重新选择包括用于分配被选择作为服务小区的目标小区的重新分布过程。 |
| The UE 100 invalidates the redistribution procedure during a predetermined period after the UE 100 transitions from the RRC connected state to the light connected state. |
用户设备（UE ）100在用户设备（UE ）100从RRC 连接状态转换到轻连接状态之后的预定时间段期间使重新分配过程无效。 |
| [0123] |
[0123] |
| Such a redistribution procedure is referred to as multi carrier load distribution (MCLD). |
这种重新分布过程被称为多载波负载分布（MCLD ）。 |
| In the MCLD, the UE 100 selects the redistribution target frequency and cell based on the redistribution parameter notified by SIB 3/5 and the IMSI of the UE 100. |
在MCLD 中，UE （100）基于SIB3/5通知的重新分配参数和UE （100）的IMSI 来选择重新分配目标频率和小区。 |
| The UE 100 performs such a redistribution procedure (redistribution target selection) when the timer (T360) has expired or when a paging indicating redistribution has been received. |
当定时器（T360）已经期满时或者当已经接收到指示重新分发的寻呼时，用户设备100执行这样的重新分发过程（重新分发目标选择）。 |
| The T360 is started when the redistribution procedure is performed and the redistribution procedure is invalidated while the T360 is in operation. |
当执行重新分发过程时启动T360，并且当T360在操作中时重新分发过程无效。 |
| [0124] |
[0124] |
| Unlike the RRC idle state, the light connected state may cause context transfer or the like as the UE 100 reselects the cell. |
与RRC 空闲状态不同，当用户设备100重选小区时，光连接状态可以引起上下文转移等。 |
| Therefore, it is not preferable to start the redistribution procedure immediately after transitioning to the light connected state. |
因此，在转换到灯连接状态之后立即开始重新分配过程不是优选的。 |
| [0125] |
[0125] |
| Therefore, when the UE 100 transitions to the light connected state, the UE 100 starts the T360 if the redistribution parameter is notified. |
因此，当用户设备（UE ）100转换到光连接状态时，如果通知了重新分配参数，则用户设备（UE ）100启动T360。 |
| Therefore, the UE 100 in the light connected state does not immediately perform load redistribution (remains in the cell for a while). |
因此，处于轻连接状态的用户设备100不会立即执行负载重新分配（在小区中保持一段时间）。 |
| After that, UE 100 performs the load redistribution when the T360 has expired. |
此后，当T360到期时，用户设备（UE ）100执行。 |
| Modification of Fifth Embodiment |
第五实施例的修改 |
| [0126] |
[0126] |
| In modification of the fifth embodiment, a difference from the fifth embodiment will be mainly described. |
在第五实施例的变型中，将主要描述与第五实施例的不同之处。 |
| [0127] |
[0127] |
| The UE 100 according to the modification of the fifth embodiment performs the cell reselection in the light connected state by using a special redistribution procedure in which the redistribution procedure (redistribution target selection) for the RRC idle state is changed. |
根据第五实施例的修改的用户设备（UE ）100通过使用特殊的再分配过程来执行轻连接状态下的小区重新选择，在该过程中，用于RRC 空闲状态的再分配过程（再分配目标选择）被改变。 |
| In other words, the special redistribution procedure for the light connected state is applied to the UE 100 in the light connected state. |
换句话说，用于光连接状态的特殊重新分布过程被应用于处于光连接状态的用户设备100。 |
| [0128] |
[0128] |
| Such a special redistribution procedure is a modification of at least one of the following 1) to 3) with respect to the redistribution procedure for RRC idle state. |
这种特殊的重新分配过程是以下1）到3）中至少一个关于RRC 空闲状态的重新分配过程的修改。 |
| [0129] |
[0129] |

1) |
| For the list (sorted list) of candidate frequencies and candidate cells that are the redistribution target, only cells associated with the current area (predetermined area) must be considered. |
对于作为重新分配目标的候选频率和候选小区的列表（排序列表），仅必须考虑与当前区域（预定区域）相关联的小区。 |
| Alternatively, the candidate frequencies and candidate cells that are the redistribution target must be cells (or frequencies at which the cells are operated) associated with the current area (predetermined area). |
或者，作为再分配目标的候选频率和候选小区必须是与当前区域（预定区域）相关联的小区（或小区工作的频率）。 |
| It should be noted that, for the serving frequency and cell, if the cell unit redistribution factor (redistributionFactorCell: information about the probability) has been notified, the candidate frequency and candidate cell sets the serving cell; |
应当注意，对于服务频率和小区，如果已经通知了小区单元再分配因子（redistributionFactorCell ：关于概率的信息），则候选频率和候选小区设置服务小区； |
| otherwise, the candidate frequency and candidate cell sets the serving frequency. |
否则，候选频率和候选小区设置服务频率。 |
| For other frequencies, in each frequency in the frequency list (InterFreqCarrierFreqList), a cell of the best cell (highest ranking) is set if the cell unit list (redistributionNeighCellList) is notified at the corresponding frequency. |
对于其它频率，在频率列表（InterFreqCarrierFreqList ）中的每个频率中，如果在相应频率处通知小区单元列表（redistributionNeighCellList ），则设置最佳小区（最高等级）的小区。 |
| Otherwise, if at least one cell satisfying S-criteria is found, the corresponding frequency is set. |
否则，如果找到满足S 准则的至少一个小区，则设置相应的频率。 |
| [0130] |
[0130] |
| 2) |
2) |
| The UE 100 must transition to the RRC connected state (for example, RRC connection reestablishment is started) if it is detected that the highest cell (best cell) in the ranking (comparison and ranking of a plurality of cells on the RSRP basis), the cell included in the ranking, or the cell satisfying S-criteria does not belong to the current area (predetermined area). |
如果检测到排序（基于RSRP 对多个小区进行比较和排序）中的最高小区（最佳小区），排序中包括的小区或满足S 准则的小区不属于当前区域（预定区域），则UE （100）必须转换到RRC 连接状态（例如，开始RRC 连接重建）。 |
| The UE 100 may transition to the RRC connected state if it is detected that the best cell is a cell having a different frequency from the frequency at which the best cell exists. |
如果检测到最佳小区是具有与存在最佳小区的频率不同的频率的小区，则用户设备100可以转换到RRC 连接状态。 |
| [0131] |
[0131] |
| 3) |
3) |
| In addition to the redistribution parameter for the RRC idle state, a redistribution parameter for the light connected state is provided to the UE 100. |
除了用于RRC 空闲状态的重新分配参数之外，用于光连接状态的重新分配参数被提供给UE （100）。 |

| Introduction |
简介 |
| [0151] |
[0151] |
| Discussion on signaling reduction to enable light connection for LTE has been started. |
已经开始讨论用于LTE 的使能光连接的信令减少。 |
| It was extensively discussed on the definition of Light Connection and the gain of paging enhancements, and finally a couple of working assumptions were agreed as follows. |
它广泛地讨论了光连接的定义和寻呼增强的增益，最后达成了如下两个工作假设。 |
| Work assumption to study the paging enhancement is “S1 connection of a UE lightly connected is kept and active, in order to hide the mobility and state transitions from CN”.Work assumption: Light connected UE can be addressed only by the trigger of paging initiated by eNB or MME. |
研究寻呼增强的工作假设是“S1保持轻度连接的UE 的连接并且是活动的，以便向CN 隐藏移动性和状态转换”.工作假设：仅可以通过eNB 或MME 发起的寻呼触发来寻址轻度连接的UE 。 |
| [0154] |
[0154] |
| In this additional note, the details of paging enhancements and Light Connection are discussed, under the working assumptions. |
在本附加说明中，将在工作假设下讨论寻呼增强和光连接的细节。 |

| Discussion |
讨论 |
| [0156] |
[0156] |
| The paging message is used to inform the UEs of the availability of MT calls, the notification of SI update, ETWS, CMAS, and EAB parameters modification, and the trigger of load redistribution. |
寻呼消息用于向UE 通知MT 呼叫的可用性，SI 更新，ETWS ，CMAS 和EAB 参数修改的通知，以及负载重新分配的触发。 |
| It was reported that the paging message makes up 26.8 % of overall RRC signaling load, as statistics in practical LTE networks. |
据报告，寻呼消息占总RRC 信令负载的26.8%，如实际LTE 网络中的统计。 |
| Considering all IEs other than the paging information are defined with 1-bit encoding type such as ENUMERATED {true} in Paging, the paging information, i.e., pagingRecordList, is the dominant cause of the signaling load due to a paging message. |
考虑到除了寻呼信息之外的所有IE 都是用1比特编码类型来定义的，例如寻呼中的ENUMERATED {true }，寻呼信息即pagingRecordList 是由于寻呼消息而引起的信令负载的主要原因。 |
| So, it's effective to consider how the actual paging information contents can be reduced for MT calls, e.g., due to S1 PAGING With such a reduction, it would be possible to reduce the number of transmitted bits within a paging message and the option for the NW to vary the number of the paging transmissions. |
因此，考虑对于例如由于S1PAGING而导致的MT 呼叫如何减少实际的寻呼信息内容是有效的。通过这样的减少，将有可能减少寻呼消息内发送的比特数以及NW 改变寻呼发送数的选项。 |
| [0157] |
[0157] |
| Proposal 1: |
建议1： |
| RAN2 should prioritize the study on the reduction of paging information conveyed within paging messages, i.e., the paging record lists. |
RAN2应当优先考虑在寻呼消息（即寻呼记录列表）内传送的寻呼信息的减少。 |

| The easiest way to significantly reduce the number of paging messages would be to force all the UEs in a tracking area to stay in Connected, but it's also the wrong approach from the UE's power consumption point of view. |
显著减少寻呼消息数量的最容易的方法是强制跟踪区域中的所有UE 保持连接，但是从UE 的功耗的观点来看，这也是错误的方法。 |
| So, this should not be used as the basis for signaling reduction of the paging message. |
因此，这不应用作寻呼消息的信令减少的基础。 |
| [0161] |
[0161] |
| Proposal 2: |
建议2： |
| UEs should not be kept in RRC Connected, i.e., Rel-13 connected mode, just to reduce the number of pages. |
UE 不应当保持在RRC 连接，即Rel-13连接模式中，只是为了减少寻呼的数量。 |

| RRC Suspended Mode |
RRC 挂起模式 |
| [0163] |
[0163] |
| It also necessary to evaluate the RRC connection suspend/resume procedures, i.e., the UP solution for NB-IoT, from the paging point of view. |
还需要从寻呼的观点来评估RRC 连接挂起/恢复过程，即NB-IOT 的UP 解决方案。 |
| Based on the agreements so far, it's assumed that the RRC connection resume is used for the UE to transition from IDLE to Connected, i.e., the UE stays in IDLE when the RRC connection is suspended. |
基于迄今为止的协议，假设RRC 连接恢复被用于UE 从IDLE 转换到连接，即，当RRC 连接被挂起时，UE 停留在IDLE 中。 |
| For example, it's agreed that “UE in connected mode with AS security activated can be released into idle mode or idle mode with the suspend indication”. |
例如，同意“激活AS 安全的连接模式中的UE 可以被释放到空闲模式或具有挂起指示的空闲模式”。 |
| In other words, the RRC Suspended mode is just a special condition of RRC IDLE. |
换句话说，RRC 挂起模式只是RRC_IDLE 的一个特殊情况。 |
| [0164] |
[0164] |
| Observation 1: |
观察1： |
| RRC Suspended mode is a special condition of the UE in IDLE. |
RRC 挂起模式是UE 在IDLE 中的特殊情况。 |
| [0165] |
[0165] |
| Thus, it is necessary for the NW to page the UE in the Suspend mode for MT calls, as similar with the UE in IDLE. |
因此，NW 必须为MT 呼叫寻呼处于暂停模式的UE ，这与IDLE 中的UE 类似。 |
| This means the gains from paging content reduction cannot be realized if the size of PagingUE-Identity is not significantly different, e.g., difference in the length between the resume ID and S-TMSI/IMSI is small. |
这意味着如果PagingUE-Identity 的大小没有显著不同，例如，在恢复ID 和S-TMSI/IMSI 之间的长度差异很小，则不能实现来自寻呼内容减少的增益。 |
| It is also necessary to consider the number of additional paging transmissions that may be needed compared to Connected state, as a result of the Suspend mode. |
作为暂停模式的结果，还必须考虑与连接状态相比可能需要的附加寻呼传输的数量。 |
| [0166] |
[0166] |
| Observation 2: |
观察2： |
| Even if the UE is in RRC Suspend mode, the NW will still need to page the UE for MT calls. |
即使UE 处于RRC 挂起模式，NW 仍然需要为MT 呼叫寻呼UE 。 |

| RRC Light Connected Mode |
RRC 灯连接模式 |
| [0168] |
[0168] |
| As discussed above, LTE has two RRC states, i.e., Connected and IDLE, and a special condition of IDLE, i.e., Suspended mode. |
如上所述，LTE 具有两个RRC 状态，即连接和空闲，以及空闲的特殊条件，即暂停模式。 |
| When the Light Connected is introduced, it should be discussed whether it's defined as a new RRC state or a special condition of the existing RRC state. |
当引入光连接时，应当讨论它是被定义为新的RRC 状态还是现有RRC 状态的特殊条件。 |
| If a new RRC state is defined, it's foreseen to define the transitions between three states, whole UE behaviors under the new state, the corresponding control messages and so on, wherein excessive standardization efforts will be necessary. |
如果定义了新的RRC 状态，则可以预见定义三种状态之间的转换，新状态下的整个UE 行为，相应的控制消息等，其中将需要过多的标准化工作。 |
| From the simplicity point of view, RAN2 should stick to the current modelling with two RRC states, and therefore, the Light Connected should be defined as a special condition of Connected. |
从简单的观点看，RAN2应该坚持当前的两个RRC 状态的建模，因此，连接的光应该被定义为连接的特殊条件。 |
| This modelling could be well matched with the working assumption “S1 connection of a UE lightly connected is kept and active, in order to hide the mobility and state transitions from CN”, which may assume ECM-Connected from the perspective of CN. |
该建模可以很好地与工作假设“保持并激活轻度连接的UE 的S1连接，以便向CN 隐藏移动性和状态转换”相匹配，从CN 的角度来看，CN 可以假设ECM 连接。 |
| [0169] |
[0169] |
| Proposal 3: |
建议3： |
| Light Connected mode should be defined as a special condition of RRC Connected, not a new state, even if it's introduced. |
光连接模式应该被定义为RRC 连接的一个特殊条件，而不是一个新的状态，即使它被引入。 |

| Issue in Paging Optimizations Due to UE Mobility |
由于UE 移动性的寻呼优化问题 |
| [0172] |
[0172] |
| Before Rel-13, paging messages were transmitted in all cells within a tracking area, regardless of whether the target UE(s) is actually located in the cell transmitting the message. |
在Rel-13之前，在跟踪区域内的所有小区中发送寻呼消息，而不管目标UE 是否实际位于发送该消息的小区中。 |
| In Rel-13, the paging optimizations were introduced by RAN3 and SA2 for the signaling reduction on Uu as well as S1, e.g., the Recommended Cells for Paging IE within S1 PAGING These Rel-13 mechanisms are efficient especially for UEs with low mobility, e.g., MTC UEs, but there may be a room for further optimizations considering UEs with normal mobility, e.g., smartphones. |
在Rel-13中，由RAN3和SA2引入寻呼优化，用于Uu 以及S1上的信令减少，例如用于在S1寻呼内寻呼IE 的推荐小区。这些Rel-13机制特别对于具有低移动性的UE （例如MTCUE ）是有效的，但是考虑到具有正常移动性的UE （例如智能电话）可能存在进一步优化的空间。 |
| For example, even when the MME determines from/informs the eNB of the recommended eNB/cell within S1 PAGING based on its knowledge of Information On Recommended Cells And ENBs at transition to ECM IDLE, the UE upon this MT call may have already moved outside of the recommended eNB/cell. |
例如，即使当MME 基于其对关于推荐小区的信息和在转换到ECM_IDLE 时的ENB 的知识，从S1PAGING中的推荐eNB/小区确定/向eNB 通知该推荐eNB/小区时，基于该MT 呼叫的UE 可能已经移动到推荐eNB/小区之外。 |
| This would result in missed pages, and the resources used for the pages are wasted. |
这将导致丢失页面，并且用于页面的资源被浪费。 |
| [0173] |
[0173] |
| Observation 3: |
观察3： |
| Paging optimizations introduced in Rel-13, e.g., the Recommended Cells for Paging IE within S1 PAGING, may work effectively only for stationary or low mobility UEs. |
在Rel-13中引入的寻呼优化，例如用于在S1PAGING内寻呼IE 的推荐小区，可以仅对固定或低移动性UE 有效地工作。 |

| Expected Gains with Paging Enhancements |
寻呼增强的预期收益 |
| [0175] |
[0175] |
| The working assumption mentions that “S1 connection of a UE lightly connected is kept and active, in order to hide the mobility and state transitions from CN”, which also implies the UE is in ECM-Connected. |
该工作假设提到“轻度连接的UE 的S1连接被保持并且是活动的，以便隐藏来自CN 的移动性和状态转换”，这也意味着UE 处于ECM 连接。 |
| In this case, the MME does not need to initiate the paging procedure when a DL data comes for the UE. |
在这种情况下，当DL 数据到达UE 时，MME 不需要发起寻呼过程。 |
| So, at least from S1 signaling point of view, the signaling reduction will be achieved with a solution under the working assumption. |
因此，至少从S1信令的观点来看，信令减少将利用工作假设下的解决方案来实现。 |
| [0176] |
[0176] |
| Observation 4: |
观察4： |
| Signaling reduction of S1 PAGING could be achieved with Light Connected mode. |
S1PAGING的信令减少可以通过光连接模式实现。 |
| [0177] |
[0177] |
| The various solutions with RAN-level paging mechanism were proposed. |
提出了具有RAN 级寻呼机制的各种解决方案。 |
| One of the benefits in the solutions is to limit the paging area. |
解决方案的好处之一是限制寻呼区域。 |
| It indeed contributes to reduce number of paging messages in a whole network, if the RAN-level paging area is set to a subset of a tracking area. |
如果RAN 级寻呼区域被设置为跟踪区域的子集，则它实际上有助于减少整个网络中的寻呼消息的数量。 |
| Similar gain may be achieved with a NW implementation today, e.g., the tracking area is configured with smaller region. |
利用当今的NW 实现可以实现类似的增益，例如，跟踪区域被配置为具有较小的区域。 |
| But it has been pointed out that such a NW implementation will cause excessive Tracking Area Updates from UEs, whereby the overall signaling will likely increase. |
但是已经指出，这样的NW 实现将导致来自UE 的过多跟踪区域更新，由此总信令将可能增加。 |
| [0178] |
[0178] |
| Although the number of paging messages can be reduced if a smaller paging area is configured, excessive Tracking Area Updates may not be preventable. |
尽管如果配置了较小的寻呼区域则可以减少寻呼消息的数量，但是过多的跟踪区域更新可能是不可防止的。 |
| [0179] |
[0179] |
| From the observations above, the introduction of paging enhancements will offer much benefit and the baseline solution is for the introduction of RAN-level paging. |
根据以上观察，寻呼增强的引入将提供很多益处，并且基线解决方案是用于引入RAN 级寻呼。 |
| Additionally, in the New RAT SI, many companies proposed to consider some kind of RAN-based paging mechanism to track UEs with low activity, in order to optimize the signaling and the performance for longer battery life. |
另外，在新的RATSI 中，许多公司建议考虑某种基于RAN 的寻呼机制来跟踪具有低活动性的UE ，以便优化信令和性能以延长电池寿命。 |
| These obviously imply the current CN-based paging mechanism has some room for improvement and an area that needs to be considered in this WI. |
这显然意味着当前基于CN 的寻呼机制具有一些改进的空间和在该WI 中需要考虑的区域。 |
| So, RAN2 should discuss further details of RAN-level paging mechanism. |

| Paging Message |
寻呼消息 |
| [0183] |
[0183] |
| If Proposal 4 is acceptable, the eNB may notice the necessity of paging upon arrival of DL data for the UE, instead of S1 PAGING The working assumption mentions “Light connected UE can be addressed only by the trigger of paging initiated by eNB or MME”, which suggests some sort of paging message is sent to the UE. |
如果建议4是可接受的，则eNB 可以注意到在用于UE 的DL 数据到达时进行寻呼的必要性，而不是S1寻呼。工作假设提到“仅可以通过eNB 或MME 发起的寻呼触发来对轻连接的UE 进行寻址”，其建议向UE 发送某种寻呼消息。 |
| From the U-plane data flow point of view, the difference at this point between the legacy paging (MME-initiated) and the new paging (eNB-initiated) is whether the DL data is still in the S-GW or already in the eNB, i.e., the routing in the CN is already done. |
从U 平面数据流的观点来看，此时传统寻呼（MME 发起的）和新寻呼（eNB 发起的）之间的差别在于DL 数据是否仍然在S-GW 中或者已经在eNB 中，即CN 中的路由已经完成。 |
| So, it would be worth considering whether the paging message is really necessary in this case, although it's natural way that the eNB sends the (RAN-level) paging message to the UE. |
因此，值得考虑在这种情况下是否真正需要寻呼消息，尽管eNB 发送（RAN 级）寻呼消息给UE 是自然的方式。 |
| One of the other possibilities may aim to eliminate any paging messages over Uu. |
其它可能性之一可能旨在消除Uu 上的任何寻呼消息。 |
| For example, the eNB sends the DL data immediately, instead of a page to the UE. |
例如，eNB 立即向UE 发送DL 数据，而不是寻呼。 |
| If the DL data volume can be managed efficiently and is comparable to the amount of data needed for paging messages, the differences may be minimal from a spectral efficiency perspective. |
如果DL 数据量可被有效地管理并且可与寻呼消息所需的数据量相比较，则从频谱效率的角度来看差异可以是最小的。 |
| The details may be related to how to define the Light Connected mode, including mobility (UE-based or NW-based), thus should be FFS. |
细节可以涉及如何定义光连接模式，包括移动性（基于UE 或基于NW ），因此应该是FFS 。 |

还可以讨论的是，用于寻呼UE 的任何传输都是在特定区域中执行的，例如现有跟踪区域，并且其被假设为一组小区，即寻呼区域。 |
| It's straight forward to introduce such a concept to minimize paging failure. |
直接引入这样的概念最小化分页失败。 |
| The paging area may be defined by availability of X2 connectivity for the UE context fetch, mobility state of the UE, balancing to spectral efficiency and so on, while it may be almost up to NW implementation. |
寻呼区域可以由用于UE 上下文提取的X2连通性的可用性，UE 的移动性状态，平衡到频谱效率等来定义，而它可以几乎达到NW 实现。 |
| [0187] |
[0187] |
| Proposal 6: |
建议书6： |
| RAN2 should introduce the paging area, which consists of a group of cells to send a transmission to page the UE. |
RAN2应当引入寻呼区域，该寻呼区域由一组小区组成，以发送用于寻呼UE 的传输。 |
| [0188] |
[0188] |
| It may be assumed that the UE mobility is transparent to the eNB as long as the UE is within the paging area, On the other hand, it should be discussed how the UE behaves when it moves outside of the paging area. |
可以假设只要UE 在寻呼区域内，UE 移动性对于eNB 是透明的.另一方面，应当讨论当UE 移动到寻呼区域之外时UE 如何工作。 |
| It's a reliable way to inform the serving cell when it happens, since it's quite similar to the existing Tracking Area Update. |
它是在服务小区发生时通知它的可靠方式，因为它非常类似于现有的跟踪区域更新。 |
| It's FFS whether the information is provided before the reselection of an outside cell or after it happens. |

或者，如果eNB 知道UE 的位置，例如通过在小区重选时来自UE 的通知，则可以避免在2.2.1节中讨论的问题。 |
| So, it's worth discussing how the eNB knows the location of the UE even in IDLE, to prevent unnecessary pages. |
因此，有必要讨论eNB 如何甚至在IDLE 中知道UE 的位置，以防止不必要的寻呼。 |
| It may be solved by the combination of the paging area, i.e., Proposal 6, and the information, i.e., Proposal 7. |

| Discussion |

[0207] |
| The working assumptions agreed in the last meeting uses the terminology “a UE lightly connected” or “Light connected UE”, which is one step ahead of the WI title, i.e., Light Connection is somewhat related to UE's condition. |
在最后一次会议中商定的工作假设使用术语“轻度连接的UE ”或“轻度连接的UE ”，其在WI 标题之前一步，即，轻度连接在某种程度上与UE 的状况相关。 |
| The objective of WID also states “Necessity of a new RAN based state” and “the solution can consider reusing the Suspend/Resume procedure”. |
WID 的目标还陈述“新的基于RAN 的状态的必要性”，以及“解决方案可以考虑重用挂起/恢复过程”。 |
| So, it's one of important aspects how to model the light connection, e.g., reusing the RRC Suspend/Resume concept or introducing a new RRC state. |
因此，如何对轻连接建模，例如重用RRC 挂起/恢复概念或引入新的RRC 状态，是一个重要的方面。 |

| Data Transmission and Reception Aspects (DL/UL/SL) |
数据传输和接收方面（DL/UL/SL ） |
| [0215] |
[0215] |
| If the Light Connection is introduced, it needs to be clarified whether the Light connected UE is required to perform data transmission and reception, i.e., downlink (DL), uplink (UL) and sidelink (SL). |
如果引入光连接，则需要阐明光连接的UE 是否需要执行数据发送和接收，即下行链路（DL ），上行链路（UL ）和侧链路（SL ）。 |
| In the existing IDLE mode, only SL is allowed with “softly” controlled by the eNB, i.e., Type 1 or Mode 2 transmission within the configuration provided in SIB18/19, while DL and UL needs the control signaling in advance, e.g., Paging, RACH and/or RRC Connection Request. |
在现有的空闲模式中，仅允许具有由eNB “软”控制的SL ，即在SIB18/19中提供的配置内的类型1或模式2传输，而DL 和UL 预先需要控制信令，例如寻呼，RACH 和/或RRC 连接请求。 |
| In Connected mode, DL and UL are “tightly” controlled by the eNB, i.e., DL assignment and UL grant, while SL may require tight control, i.e., Type 2B or Mode 1 transmission by dedicated resource or SL grant, depending on the eNB's preference. |
在连接模式中，DL 和UL 由eNB “紧密地”控制，即DL 分配和UL 授权，而SL 可能需要紧密控制，即通过专用资源或SL 授权的类型2B或模式1传输，这取决于eNB 的偏好。 |
| [0216] |

连接中的UE 执行各种类型的测量，即CSI 测量，RLM 测量和RRM 测量，以及测量反馈/报告。 |
| On the other hand, UEs in IDLE only perform RRM measurement for cell reselection without reporting, i.e., UE-based mobility. |
另一方面，IDLE 中的UE 仅执行用于小区重选的RRM 测量，而不进行报告，即基于UE 的移动性。 |
| With Light Connection, it is necessity to discuss which of these measurements and feedback/reporting needs to be supported, which should depend on whether Light Connection is more like CONNECTED or IDLE. |
对于光连接，有必要讨论需要支持这些测量和反馈/报告中的哪一个，这应当取决于光连接是否更像CONNECTED 或IDLE 。 |

| Activation and Deactivation Aspects (SCell, SPS) |
激活和去激活方面（SCell ，SPS ） |

| The SCell(s) could be configured for Carrier Aggregation and Dual Connectivity, and these are activated or deactivated by e.g., the MAC Control Element. |
SCell 可以被配置用于载波聚合和双重连接，并且这些由例如MAC 控制单元激活或去激活。 |
| Also, SPS is configured for efficient delivery of e.g., VoLTE, and it's activated by PDCCH scrambled with SPS-RNTI. |
而且，SPS 被配置用于有效地传送例如VoLTE ，并且它被用SPS-RNTI 加扰的PDCCH 激活。 |
| In the current specification, SCell(s)/SPS are de-configured when the UE transitions to IDLE, and it's reconfigured as needed when/after the UE transitions back to Connected. |
在当前规范中，当UE 转换到IDLE 时，SCell/SPS 被解除配置，并且当UE 转换回Connected 时/之后，它根据需要被重新配置。 |
| With Light Connection, it's also necessary to define whether SCell(s) and SPS are deactivated or even de-configured. |
通过光连接，还需要定义SCell 和SPS 是否被去激活或者甚至被解除配置。 |
| [0222] |
