- LTE-A Long Term Evolution Advance
- CA Carrier Aggregation
- UE User Equipment
- CA Carrier Aggregation
- the maximum downlink transmission bandwidth supported by the system is 20MHz.
- Carrier aggregation is to aggregate two or more component carriers (CC) to support more than 20MHz and no more than 100MHz. Transmission bandwidth.
- the component carriers are classified into backward compatible component carriers and non-backward compatible component carriers according to whether they are compatible with the LTE system.
- the backward compatible component carrier is compatible with the LTE system, and the UE that does not have the carrier aggregation capability (for the convenience of description, the LTE UE is referred to as the LTE UE for short) is also allowed to access, and the UE with the carrier aggregation capability is also allowed.
- LTE-A UE access; instead of backward compatible component carriers only allow LTE-A UE access.
- the carrier or the non-backward compatible component carrier is used together, that is, the special component carrier does not allow the UE in the idle state to access, and is only allowed to be allocated to the LTE-A UE that has accessed the backward compatible component carrier or the non-backward compatible component carrier. Used in the connected state.
- the LTE UE that does not have the carrier aggregation capability can reside on only one backward compatible component carrier, whether it is in the idle state or the connected state.
- the component carrier here refers to a certain cell on the component carrier, which is convenient for description, referred to as component carrier.
- the behavior of the LTE UE in the idle state and the connected state is performed according to the provisions of the LTE system, and is not affected.
- the LTE-A UE with carrier aggregation capability can only reside on one component carrier (backward compatible or non-backward compatible component carrier) in the idle state.
- the base station can allocate other required component carriers to the UE through dedicated RRC signaling (such as RRC Connection Reconfiguration, RRC connection reconfiguration).
- Carrier that is, the LTE-A UE can simultaneously communicate on multiple component carriers in the connected state.
- the LTE-A UE selects only the E-UTRAN Cell Global Identifier (ECGI) and the tracking area code (Tracking Area) provided on one component carrier.
- Code, TAC and other information are used as input information for mobility management such as tracking area update of the non-access stratum (NAS), and the physical cell identity (Physical Cell Identity, the frequency provided on the component carrier).
- the information such as PCI is used as the input information for the security protection of the UE.
- the component carrier is referred to as the primary serving component carrier, and the other component carriers are referred to as the non-primary serving component carrier.
- the dedicated RRC signaling for allocating the newly added component carrier carries the resource configuration necessary for the UE to perform data transmission on the newly added component carrier, including common resource configuration and dedicated resource configuration.
- the foregoing common resource configuration is obtained by the UE receiving the system message of the serving cell in the existing LTE system, but the UE does not camp or access on the configured new component carrier before receiving the dedicated RRC signaling. That is, the UE has not obtained the system message on the configured new component carrier, so in order to enable the UE to perform data transmission on the configured new component carrier, the configured new RRC signaling transmits the configured new component carrier.
- PUSCH physical uplink shared channel
- PDSCH physical downlink shared channel
- the dedicated resource configuration is the dedicated configuration on the PDSCH configured in the existing LTE system, the dedicated configuration on the PUSCH, and the dedicated configuration of the uplink power control (all the information is not listed here).

- Behavior 2 After the base station and the UE add a new component carrier, the data is not immediately sent and received on the newly added component carrier, that is, the base station does not send the service data to the UE on the newly added component carrier.
- the UE saves the configuration information on the newly added component carrier, and does not send the service data to the base station on the newly added component carrier, and waits for further action of the base station.
- the subsequent base station can activate the component carrier according to the service requirement. After the component carrier is activated, the base station and the UE can perform data transmission and reception on the component carrier.
- the UE monitors the paging message of the serving cell or periodically receives the system information block 1 (SIB1) of the serving cell, according to whether the system message is changed in the paging message or by comparing the newly received SIB1.
- SIB1 system information block 1
- the system message flag (systemlnfoValueTag) in the system and the systemlnfoValueTag value in the originally received SIB1 saved by the UE determine whether it is necessary to update the system message of the serving cell, that is, re-receive all system messages broadcast by the serving cell.
- the base station informs the UE of the common resource configuration information on the component carrier by using dedicated RRC signaling.
- the UE After receiving the common resource configuration information, the UE continues to use the existing LTE system message update mechanism and is configured by monitoring.

Whether the system message (common resource configuration) on CC1 needs to be updated. The specific judgment is based on the fact that if systemlnfoValueTagl is equal to systemInfoValueTag2, no update is required; if systemlnfoValueTagl is not equal to systemInfoValueTag2, it needs to be updated.
- the systemInfoFValueTagl is not equal to the systemInfoValueTag2, so the serving base station carries the common resource configuration information (that is, the information of the system message that needs to be updated) that needs to be updated on the CC1 in the activation indication, or the serving base station instructs the UE to update the CC1 in the activation indication. system information.
- the UE activates CC1, and feeds back an activation completion indication to the serving base station.
- the public resource configuration information that needs to be updated in the activation indication is taken as an example, and the UE can directly replace the locally stored common resource configuration information by using the received common resource configuration information. If the UE is instructed to update the system message on CC1, the behavior of the UE after receiving the activation indication is the same as steps S305-S306.

Description
一种***消息更新的方法和*** Method and system for system message update
技术领域 Technical field
本发明涉及移动通信领域, 尤其涉及一种***消息更新的方法和***。 The present invention relates to the field of mobile communications, and in particular, to a method and system for system message update.
背景技术 Background technique
为向移动用户提供更高的数据速率, 高级长期演进*** (Long Term Evolution Advance,简称为 LTE-A )提出了载波聚合技术( Carrier Aggregation, CA ) , 其目的是为具有相应能力的用户设备(User Equipment, UE )提供更 大宽带, 提高 UE的峰值速率。 长期演进***( Long Term Evolution , LTE ) 中, ***支持的最大下行传输带宽为 20MHz, 载波聚合是将两个或者更多的 分量载波(Component Carriers, CC )聚合起来支持大于 20MHz, 最大不超 过 100MHz的传输带宽。 In order to provide higher data rates to mobile users, the Long Term Evolution Advance (LTE-A) proposes Carrier Aggregation (CA), which is designed for user equipment with corresponding capabilities ( User Equipment, UE) provides greater bandwidth and increases the peak rate of the UE. In Long Term Evolution (LTE), the maximum downlink transmission bandwidth supported by the system is 20MHz. Carrier aggregation is to aggregate two or more component carriers (CC) to support more than 20MHz and no more than 100MHz. Transmission bandwidth.
分量载波按是否兼容 LTE***, 可以分为后向兼容分量载波和非后向兼 容分量载波。 其中后向兼容分量载波兼容 LTE***, 可以允许不具备载波聚 合能力的 UE (为描述方便, 本发明专利简称 LTE UE )接入, 也允许具备载 波聚合能力的 UE (为描述方便, 本发明专利简称 LTE-A UE )接入; 而非后 向兼容分量载波只允许 LTE-A UE接入。 除此之外出于提高频语使用效率和 在异构网络中更好的进行干扰控制等原因, 可能还会弓 )入一种特殊的分量载 波, 此特殊的分量载波只能与后向兼容分量载波或非后向兼容分量载波一起 使用, 即此特殊的分量载波不允许空闲态的 UE接入, 仅允许分配给已经接 入后向兼容分量载波或非后向兼容分量载波的 LTE-A UE在连接态使用。 The component carriers are classified into backward compatible component carriers and non-backward compatible component carriers according to whether they are compatible with the LTE system. The backward compatible component carrier is compatible with the LTE system, and the UE that does not have the carrier aggregation capability (for the convenience of description, the LTE UE is referred to as the LTE UE for short) is also allowed to access, and the UE with the carrier aggregation capability is also allowed. Referred to as LTE-A UE) access; instead of backward compatible component carriers only allow LTE-A UE access. In addition, for the sake of improving the efficiency of frequency usage and better interference control in heterogeneous networks, it may also be possible to enter a special component carrier, which can only be compatible with backward components. The carrier or the non-backward compatible component carrier is used together, that is, the special component carrier does not allow the UE in the idle state to access, and is only allowed to be allocated to the LTE-A UE that has accessed the backward compatible component carrier or the non-backward compatible component carrier. Used in the connected state.
引入载波聚合技术后, 不论是空闲态还是连接态, 不具备载波聚合能力 的 LTE UE只能驻留在一个后向兼容的分量载波上(需要说明的是, 一个分 量载波上可以存在多个小区, 这里的分量载波特指分量载波上的某个小区, 为描述方便, 简称分量载波) , LTE UE在空闲态和连接态的行为按照 LTE ***的规定执行, 不受影响。 而具备载波聚合能力的 LTE-A UE在空闲态仅 能驻留在一个分量载波上(后向兼容或非后向兼容的分量载波), LTE-A UE 在该分量载波上成功接入后, 即在该分量载波建立无线资源控制 (Radio
Resources Control, RRC )连接后, 根据业务需要, 基站可以通过专用 RRC 信令 (如 RRC Connection Reconfiguration , RRC连接重配置)为 UE分配其 他需要的分量载波(为描述方便,本发明专利简称新增分量载波), 即 LTE-A UE在连接态下可以同时在多个分量载波通信。连接态下 LTE-A UE同时工作 的多个分量载波中 , LTE-A UE仅选择一个分量载波上提供的演进型全球小区 标识( E-UTRAN Cell Global Identifier, ECGI )和跟踪区代码 ( Tracking Area Code, TAC )等信息作为非接入层(Non-Access Stratum , NAS )进行跟踪 区位置更新等移动性管理的输入信息, 并以该分量载波上提供的频率, 物理 小区标识(Physical Cell Identity, PCI )等信息作为 UE进行安全保护的输入 信息, 为描述方便, 本发明专利中称该分量载波为主服务分量载波, 称其他 分量载波为非主服务分量载波。 After the carrier aggregation technology is introduced, the LTE UE that does not have the carrier aggregation capability can reside on only one backward compatible component carrier, whether it is in the idle state or the connected state. (Note that multiple cells may exist on one component carrier. The component carrier here refers to a certain cell on the component carrier, which is convenient for description, referred to as component carrier. The behavior of the LTE UE in the idle state and the connected state is performed according to the provisions of the LTE system, and is not affected. The LTE-A UE with carrier aggregation capability can only reside on one component carrier (backward compatible or non-backward compatible component carrier) in the idle state. After the LTE-A UE successfully accesses the component carrier, That is, establishing radio resource control on the component carrier (Radio) After the connection of the resource control, RRC, the base station can allocate other required component carriers to the UE through dedicated RRC signaling (such as RRC Connection Reconfiguration, RRC connection reconfiguration). Carrier), that is, the LTE-A UE can simultaneously communicate on multiple component carriers in the connected state. Among the multiple component carriers in which the LTE-A UE works in the connected state, the LTE-A UE selects only the E-UTRAN Cell Global Identifier (ECGI) and the tracking area code (Tracking Area) provided on one component carrier. Code, TAC and other information are used as input information for mobility management such as tracking area update of the non-access stratum (NAS), and the physical cell identity (Physical Cell Identity, the frequency provided on the component carrier). The information such as PCI is used as the input information for the security protection of the UE. For convenience of description, the component carrier is referred to as the primary serving component carrier, and the other component carriers are referred to as the non-primary serving component carrier.
在上述分配新增分量载波的专用 RRC信令中会携带 UE在新增分量载波 上进行数据传输所必须的资源配置, 包括公共资源配置和专用资源配置。 其 中上述公共资源配置在现有 LTE***中 UE是通过接收服务小区的***消息 获取到的, 但是由于 UE在接收上述专用 RRC信令之前尚未在所配置的新增 分量载波上驻留或接入, 也即 UE尚未获取到所配置的新增分量载波上的系 统消息, 因此为了让 UE在所配置的新增分量载波上进行数据传输, 该专用 RRC信令中发送所配置的新增分量载波上的公共资源配置, 包括新增分量载 波的频点,带宽, PCI,物理下行共享信道( Physical Downlink Shared Channel, PDSCH )上的公共配置, 物理上行共享信道( Physical Uplink Shared Channel, PUSCH )上的公共配置, 上行功率控制的公共配置等信息 (此处不——罗列 所有信息 ) 。 其中上述专用资源配置即现有 LTE***中所配置的 PDSCH上 的专用配置, PUSCH上的专用配置, 上行功率控制的专用配置等信息(此处 不一一罗列所有信息) 。 The dedicated RRC signaling for allocating the newly added component carrier carries the resource configuration necessary for the UE to perform data transmission on the newly added component carrier, including common resource configuration and dedicated resource configuration. The foregoing common resource configuration is obtained by the UE receiving the system message of the serving cell in the existing LTE system, but the UE does not camp or access on the configured new component carrier before receiving the dedicated RRC signaling. That is, the UE has not obtained the system message on the configured new component carrier, so in order to enable the UE to perform data transmission on the configured new component carrier, the configured new RRC signaling transmits the configured new component carrier. The common resource allocation on the physical uplink shared channel (PUSCH) on the physical uplink shared channel (PUSCH), including the frequency of the newly added component carrier, the bandwidth, the PCI, and the physical downlink shared channel (PDSCH). Common configuration, public configuration of uplink power control, etc. (not here - list all information). The dedicated resource configuration is the dedicated configuration on the PDSCH configured in the existing LTE system, the dedicated configuration on the PUSCH, and the dedicated configuration of the uplink power control (all the information is not listed here).
基站和 UE增加上述新增分量载波后的行为可以有两种: There are two types of behaviors after the base station and the UE add the above-mentioned new component carrier:
行为 1 : 基站和 UE增加某一新增分量载波后, 即在该新增分量载波上进 行数据收发, 即该新增分量载波在配置后即被激活。 Behavior 1: After the base station and the UE add a new component carrier, the data is transmitted and received on the newly added component carrier, that is, the newly added component carrier is activated after being configured.
行为 2: 基站和 UE增加某一新增分量载波后, 并不立即在该新增分量载 波上进行数据收发, 即基站并不在新增该分量载波上向 UE发送业务数据,
UE保存该新增分量载波上的配置信息,也并不在该新增分量载波上向基站发 送业务数据, 等待基站的进一步动作。 后续基站可以根据业务需要激活该分 量载波, 该分量载波被激活后, 基站和 UE即可在该分量载波上进行数据收 发了。 Behavior 2: After the base station and the UE add a new component carrier, the data is not immediately sent and received on the newly added component carrier, that is, the base station does not send the service data to the UE on the newly added component carrier. The UE saves the configuration information on the newly added component carrier, and does not send the service data to the base station on the newly added component carrier, and waits for further action of the base station. The subsequent base station can activate the component carrier according to the service requirement. After the component carrier is activated, the base station and the UE can perform data transmission and reception on the component carrier.
在现有 LTE***中, UE通过监听服务小区的寻呼消息或者周期性的接 收服务小区的***信息块 1 ( SIB1 ) , 根据寻呼消息中是否指示***消息改 变或者通过对比新接收到的 SIB1 中的***消息标志 ( systemlnfoValueTag ) 与 UE本地保存的原来接收到的 SIB1中的 systemlnfoValueTag值, 判断是否 需要更新服务小区的***消息, 即重新接收服务小区广播的所有***消息。 在载波聚合中, 基站通过专用 RRC信令通知 UE新增分量载波上的公共资源 配置信息, UE接收该公共资源配置信息后, 如果继续釆用现有 LTE的*** 消息更新机制, 通过监听所配置的各个分量载波上的寻呼消息或者周期性的 接收各分量载波上的 SIB1 判断是否需要更新各分量载波上的公共资源配置 信息, 会大大增加 UE的耗电量, 影响用户设备的电池使用时间。 In the existing LTE system, the UE monitors the paging message of the serving cell or periodically receives the system information block 1 (SIB1) of the serving cell, according to whether the system message is changed in the paging message or by comparing the newly received SIB1. The system message flag (systemlnfoValueTag) in the system and the systemlnfoValueTag value in the originally received SIB1 saved by the UE determine whether it is necessary to update the system message of the serving cell, that is, re-receive all system messages broadcast by the serving cell. In carrier aggregation, the base station informs the UE of the common resource configuration information on the component carrier by using dedicated RRC signaling. After receiving the common resource configuration information, the UE continues to use the existing LTE system message update mechanism and is configured by monitoring. The paging message on each component carrier or the periodic reception of the SIB1 on each component carrier determines whether it is necessary to update the common resource configuration information on each component carrier, which greatly increases the power consumption of the UE and affects the battery life of the user equipment. .

下面结合附图及具体实施例对本发明进行详细说明。 The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
实施例一 Embodiment 1
用户设备 UE 为具有载波聚合能力的 LTE-A UE , 以频分双工模式 ( Frequency Division Duplex, FDD )为例, 如图 1所示, 分量载波 2 (下行频 点为 £2, 上行频点为 £2' ) , 简称 CC2 ( DL £2, UL f2' )为该 UE的主服务
分量载波, UE通过读取 CC2上的***消息获取到了 CC2上的公共资源配置 信息, 通过 RRC连接重配置消息获取到了 CC2上的专用资源配置信息。 因 为业务需要,服务基站通过专用 RRC信令为该 LTE-A UE分配了两个新增分 量载波, 分量载波 1和分量载波 3 , 即 CCl ( DL fl , UL fl' )和 CC3 ( DL G , UL β,),该专用 RRC信令中携带 UE在 CCl和 CC3上进行数据传输所必须 的资源配置, 包括公共资源配置和专用资源配置。 The user equipment UE is an LTE-A UE with carrier aggregation capability, and takes a Frequency Division Duplex (FDD) as an example. As shown in FIG. 1, component carrier 2 (downlink frequency is £2, uplink frequency point) For £2'), CC2 (DL £2, UL f2' for short) is the main service of the UE. The component carrier, the UE obtains the common resource configuration information on the CC2 by reading the system message on the CC2, and obtains the dedicated resource configuration information on the CC2 through the RRC connection reconfiguration message. The service base station allocates two new component carriers, component carrier 1 and component carrier 3, namely CCl (DL fl , UL fl' ) and CC3 ( DL G , for the LTE-A UE through dedicated RRC signaling. UL β,), the dedicated RRC signaling carries the resource configuration necessary for the UE to perform data transmission on CCl and CC3, including common resource configuration and dedicated resource configuration.
CC2为该 UE的主服务分量载波 , UE在 CC2上通过监听服务基站在 CC2 上发送的寻呼消息, 或者周期性检测 CC2上的 SIB1进行 CC2上***消息的 更新, 即 UE根据寻呼消息中是否指示***消息改变或者通过对比新接收到 的 SIB1中的 systemlnfoValueTag与 UE本地保存的原来接收到的 SIB1 中的 systemlnfoValueTag值, 判断是否需要更新服务小区的***消息(具体更新方 法为现有技术, 本发明专利不再赘述) 。 The CC2 is the primary serving component carrier of the UE. The UE listens to the paging message sent by the serving base station on the CC2 on the CC2, or periodically detects the SIB1 on the CC2 to update the system message on the CC2, that is, the UE according to the paging message. Whether the system message is changed or the systemInfo value of the service cell is updated by comparing the systemlnfoValueTag in the newly received SIB1 with the systemInfofoValueTag value in the originally received SIB1 saved by the UE (the specific update method is prior art, this The invention patent will not be described again).
本实施例中, UE根据服务基站的指示更新非主服务分量载波上的***消 息, 具体流程如图 2所示: In this embodiment, the UE updates the system message on the non-primary service component carrier according to the indication of the serving base station, and the specific process is as shown in FIG. 2:
5201、 服务基站需要改变 CCl和 CC3上的***消息, 服务基站通知 UE CC1和 CC3上***消息改变。 5201. The serving base station needs to change system messages on CCl and CC3, and the serving base station notifies the UEs that CC1 and CC3 change the system message.
服务基站釆用专用 RRC信令(如 RRC连接重配置消息 )通知 UE CC1 和 CC3上***消息改变, 在该***消息改变的指示中需要携带表征分量载波 CC1和 CC3的指示, 可以是分量载波的标识信息, 或者分量载波的绝对载频 信息; 具体可以是基站为 UE分配的各 CC上的标识, 比如 CC1的标识为 1 , CC3的标识为 3; 还可以是 CC1和 CC3的绝对载频号 (ARFCN ) 。 The serving base station notifies the UE of the system message change on CC1 and CC3 by using dedicated RRC signaling (such as the RRC connection reconfiguration message), and needs to carry an indication indicating the component carriers CC1 and CC3 in the indication of the system message change, which may be a component carrier. The identification information, or the absolute carrier frequency information of the component carrier; specifically, the identifier of each CC allocated by the base station to the UE, for example, the identifier of CC1 is 1, the identifier of CC3 is 3, and the absolute carrier frequency of CC1 and CC3 may also be (ARFCN).
基站在主服务分量载波 CC2上向 UE发送该***消息改变的指示,或者 , 如果当前 UE和基站正在 CC1、 CC3进行数据收发, 即 CC1、 CC3处于激活 状态, 基站也可以在 CC1或 CC3上向 UE发送***消息改变的指示。 The base station sends an indication of the system message change to the UE on the primary serving component carrier CC2, or if the current UE and the base station are transmitting and receiving data in CC1 and CC3, that is, CC1 and CC3 are in an active state, the base station may also be in CC1 or CC3. The UE sends an indication of a system message change.
需要说明的是,本实施例假设正好 CC1和 CC3上的***消息同时需要修 改的情况, 如果在某一时刻只有一个 CC上的***消息需要修改, 则服务基 站只需要通知 UE该 CC上***消息改变。 It should be noted that, in this embodiment, it is assumed that the system messages on CC1 and CC3 need to be modified at the same time. If only one system message on the CC needs to be modified at a certain time, the serving base station only needs to notify the UE of the system message on the CC. change.
5202、 UE接收到 CCl和 CC3上***消息改变的指示后, 开始接收并读
取 CC1和 CC3上的***消息主信息块(MIB ) , SIB1 , SIB2。 5202. After receiving the indication of the system message change on the CCl and the CC3, the UE starts to receive and read. Take the system message master information block (MIB), SIB1, SIB2 on CC1 and CC3.
需要说明的是 MIB中所包含分量载波的下行带宽, ***帧号 (SFN ) , 物理混合自动重传指示信道 ( Physical Hybrid ARQ Indicator Channel, PHICH ) 配置信息, 这些信息一般不会改变; SIB1包含 UE接收其他***消息 (比如 SIB2 ) 所需要的调度信息, 调度信息一般不会改变, 除此之外没有包含 UE 在连接状态进行数据传输所需要的信息; SIB2中包含 UE在连接态下进行数 据传输所需要的公共配置信息,这些信息有可能改变。因此优化的,步骤 S201 服务基站通知 UE***消息改变的指示中, 可以指示 UE仅仅是 SIB2中的系 统消息改变了, UE接收到该指示后, 可以直接接收并读取 SIB2中的信息, 不需要接收 MIB和 SIB1 , 从而确保 UE快速更新修改后的公共配置信息。 It should be noted that the downlink bandwidth of the component carrier included in the MIB, the system frame number (SFN), and the Physical Hybrid ARQ Indicator Channel (PHICH) configuration information, which generally do not change; SIB1 includes the UE. The scheduling information required for receiving other system messages (such as SIB2), the scheduling information is generally not changed, and the information required for the UE to transmit data in the connection state is not included; SIB2 includes the UE transmitting data in the connected state. The public configuration information required, which may change. Therefore, in step S201, the serving base station notifies the UE that the system message is changed, and may indicate that the UE only changes the system message in the SIB2. After receiving the indication, the UE may directly receive and read the information in the SIB2, and does not need to The MIB and SIB1 are received to ensure that the UE quickly updates the modified public configuration information.
S203、 UE根据***消息更新结果向服务基站发送反馈信息,通知服务基 站***消息接收完成。 S203. The UE sends feedback information to the serving base station according to the system message update result, to notify the service base station system that the message reception is completed.
UE釆用专用 RRC信令(如 RRC连接重配置完成消息 )通知服务基站系 统消息接收完成。 The UE notifies the serving base station system that the message reception is completed by using dedicated RRC signaling (e.g., RRC Connection Reconfiguration Complete message).
如果 UE在***规定的时间内成功接收并读取到了 CC1和 CC3上的*** 消息, 则 UE通知服务基站***消息接收完成, 该***消息接收完成指示中 指示 UE成功接收到了 CC1和 CC3上的***消息。 If the UE successfully receives and reads the system messages on CC1 and CC3 within the time specified by the system, the UE notifies the serving base station system that the message reception is completed, and the system message receiving completion indication indicates that the UE successfully receives the systems on CC1 and CC3. Message.
如果 UE在***规定的时间内在 CC1和 /或 CC3上未成功接收到***消 息, 则 UE在上述通知服务基站***消息接收完成的指示中携带已经成功接 收到***消息的分量载波的信息, 或者携带未成功接收到***消息的分量载 波的信息, 具体方式可以是携带表征分量载波的分量载波标识, 或者表征分 量载波的分量载波的 ARFCN。或者如果 UE在***规定时间内在 CC1和 CC3 上均未成功接收到***消息, 则 UE在上述通知服务基站***消息接收完成 的指示中指示***消息接收失败。 If the UE does not successfully receive the system message on the CC1 and/or the CC3 within the time specified by the system, the UE carries the information of the component carrier that has successfully received the system message, or carries The information of the component carrier that does not successfully receive the system message may be carried by the component carrier identifier that represents the component carrier, or the ARFCN that represents the component carrier of the component carrier. Or if the UE does not successfully receive the system message on CC1 and CC3 within the specified time of the system, the UE indicates that the system message reception fails in the indication that the service base station system message is completed.
上述***消息根据步骤 S202的描述, 为 MIB和 SIB1和 SIB2, 或者仅 仅是 SIB2。 The above system message is MIB and SIB1 and SIB2, or only SIB2, according to the description of step S202.
UE在主服务分量载波上通知服务基站***消息接收完成,或者如果当前 UE和基站正在 CC1、 CC3进行数据收发, 即 CC1、 CC3处于激活状态, 则
UE也可以选择 CCl (若***消息接收成功)或 CC3 (若***消息接收成功) 上通知服务基站***消息接收完成。 The UE notifies the serving base station system that the message reception is completed on the primary service component carrier, or if the current UE and the base station are performing data transmission and reception on CC1 and CC3, that is, CC1 and CC3 are in an active state, then The UE may also select CCl (if the system message is successfully received) or CC3 (if the system message is successfully received) to notify the serving base station that the message reception is completed.
需要说明的是, 本步骤为可选步骤, 不管 UE在 CC1和 CC3上***消息 接收成功与否, UE都可以不向服务基站反馈任何信息, 如果 UE未成功读取 到某个分量载波上的***消息, 即未更新某个分量载波上的公共资源配置信 息, 基站可以通过现有技术(如测量报告, 信道质量指示, 无线链路失败检 测等技术)判断基站与 UE无法在该分量载波上进行正常的通信, 从而釆取 进一步的措施, 如删除该分量载波, 去激活该分量载波等。 It should be noted that this step is an optional step. Regardless of whether the UE successfully receives the system message on CC1 and CC3, the UE may not feed back any information to the serving base station, if the UE does not successfully read the component carrier. The system message, that is, the common resource configuration information on a certain component carrier is not updated, and the base station can judge that the base station and the UE cannot be on the component carrier by using technologies (such as measurement report, channel quality indicator, and radio link failure detection). Normal communication is performed to take further measures such as deleting the component carrier, deactivating the component carrier, and the like.
本实施例中,分量载波 CC1和 CC3可以是激活的分量载波,也可以是配 置了但未被服务基站激活的分量载波。 In this embodiment, the component carriers CC1 and CC3 may be activated component carriers, or may be component carriers configured but not activated by the serving base station.
实施例二 Embodiment 2
用户设备 UE为具有载波聚合能力的 LTE-A UE, 以 FDD为例, 服务基 站当前为 UE 配置了两个分量载波, 分量载波 1 CC1 ( DL fl , UL fl' )和分 量载波 2 CC2 ( DL £2, UL G' ) 。 其中分量载波 2为该 UE的主服务分量载 波, UE通过读取 CC2上的***消息获取到了 CC2上的公共资源配置信息, 通过 RRC连接重配置消息获取到了 CC2上的专用资源配置信息;分量载波 1 为非主服务分量载波, 服务基站通过专用 RRC信令为 UE配置了分量载波 1 上的公共资源配置和专用资源配置, 但因暂无业务需要, 服务基站并没有激 活分量载波 1 , 即 UE和服务基站当前仅在分量载波 2上进行业务通信, 而分 量载波 1为非激活的分量载波 , UE和基站并不在该分量载波上进行业务通信。 The user equipment UE is an LTE-A UE with carrier aggregation capability. Taking FDD as an example, the serving base station currently configures two component carriers for the UE, component carrier 1 CC1 (DL fl , UL fl ' ) and component carrier 2 CC 2 ( DL £2, UL G'). The component carrier 2 is the primary serving component carrier of the UE, and the UE obtains the common resource configuration information on the CC2 by reading the system message on the CC2, and obtains the dedicated resource configuration information on the CC2 through the RRC connection reconfiguration message; the component carrier 1 is a non-primary service component carrier, and the serving base station configures the common resource configuration and the dedicated resource configuration on the component carrier 1 for the UE through dedicated RRC signaling, but the serving base station does not activate the component carrier 1, ie, the UE, because there is no service requirement. The serving base station currently only performs service communication on the component carrier 2, and the component carrier 1 is an inactive component carrier, and the UE and the base station do not perform service communication on the component carrier.
CC2为该 UE的主服务分量载波 , UE在 CC2上通过监听服务基站在 CC2 上发送的寻呼消息, 或者周期性检测 CC2上的 SIB1进行 CC2上***消息的 更新, 即 UE根据寻呼消息中是否指示***消息改变或者通过对比新接收到 的 SIB1中的 systemlnfoValueTag与 UE本地保存的原来接收到的 SIB1 中的 systemlnfoValueTag值, 判断是否需要更新服务小区的***消息。 The CC2 is the primary serving component carrier of the UE. The UE listens to the paging message sent by the serving base station on the CC2 on the CC2, or periodically detects the SIB1 on the CC2 to update the system message on the CC2, that is, the UE according to the paging message. Whether to indicate the system message change or to compare whether the systemInfofoValueTag in the newly received SIB1 and the systemInfofoValueTag value in the originally received SIB1 saved locally by the UE determine whether the system message of the serving cell needs to be updated.
CC1当前为非激活的分量载波, UE 不更新 CC1上的***消息直到 CC1 被服务基站激活, UE根据服务基站的指示更新 CC1上的***消息的过程如
图 3所示: CC1 is currently a non-active component carrier, the UE does not update the system message on CC1 until CC1 is activated by the serving base station, and the UE updates the system message on CC1 according to the indication of the serving base station. Figure 3 shows:
5301、 服务基站通过专用 RRC信令为 UE配置了 CC1但并未激活 CC1。 该专用 RRC信令中携带 CC1上的公共资源配置, 专用资源配置和配置 CC1 时 CC1上的***消息标志( systemlnfoValueTagl ) , UE保存以上信息但并不 激活 CC1。 5301. The serving base station configures CC1 for the UE by using dedicated RRC signaling but does not activate CC1. The dedicated RRC signaling carries the common resource configuration on CC1, the dedicated resource configuration and the system message flag (systemlnfoValueTagl) on CC1 when CC1 is configured. The UE saves the above information but does not activate CC1.
5302、 UE在接收到 S301CC1上的配置信息到 CC1被服务基站激活之间, 不更新 CC1上的***消息, 即 UE不监听 CC1上的寻呼消息, 也不周期性的 检测 CC1上的 SIB1。 5302. The UE does not update the system message on the CC1 when the configuration information on the S301CC1 is received until the CC1 is activated by the serving base station, that is, the UE does not monitor the paging message on the CC1, and does not periodically detect the SIB1 on the CC1.
因为 CC1处于非激活状态,UE和服务基站并不在 CC1上进行业务传输, 因此 UE不需要更新 CC1上的***消息。 Since CC1 is in an inactive state, the UE and the serving base station do not perform traffic transmission on CC1, so the UE does not need to update the system message on CC1.
S303、服务基站根据业务需要激活 CC1 ,并在该激活指示中携带当前 CC1 上的***消息标志 ( systemInfoValueTag2 ) 。 S303. The serving base station activates CC1 according to the service requirement, and carries the system message flag (systemInfoValueTag2) on the current CC1 in the activation indication.
服务基站在主服务分量载波 CC2上通知 UE激活 CC1。 The serving base station notifies the UE to activate CC1 on the primary serving component carrier CC2.
S304、 UE根据 S301接收并保存在本地的***消息的标识信息 (比如, ***消息标志 systemlnfoValueTagl )和接收到激活指示时所携带的***消息 的标识信息 (比如, systemInfoValueTag2 )判断 UE需要更新 CC1上的*** 消息。 S304. The UE determines, according to the identifier information (for example, the system message flag systemInfoValueTagl) of the system message received and saved in the S301, and the identifier information of the system message (for example, systemInfoValueTag2) that is received when the activation indication is received, to determine that the UE needs to update the CC1. system information.
具体判断依据为 , ^口果 systemInfoValueTag2与 systemlnfoValueTagl相等, 则不需要更新 CC1上的***消息, UE直接向服务基站反馈激活成功指示; 如果 systemInfoValueTag2与 systemlnfoValueTagl不相等, 则需要更新 CC1 上的***消息,本实施例中 systemInfoValueTag2与 systemlnfoValueTagl不相 等。 The specific judgment is based on: ^The system informationValueTag2 is equal to the systemlnfoValueTagl, then the system message on the CC1 is not required to be updated, and the UE directly feeds back the activation success indication to the serving base station; if the systemInfoValueTag2 and the systemlnfoValueTagl are not equal, the system message on the CC1 needs to be updated. In the embodiment, systemInfoValueTag2 is not equal to systemlnfoValueTagl.
需要说明的是, 本实施例假设 S304为服务基站配置 CC1后第一次激活 CC1 , 如果 CC1在此之前被激活过, 则 UE可能在 CC1激活的状态更新过 CC1上的***消息, 则此处所述的 systemlnfoValueTagl则为 UE最后一次更 新 CC1上的***消息时所获取到的***消息标志。 It should be noted that, this embodiment assumes that S304 activates CC1 for the first time after configuring CC1 for the serving base station. If CC1 is activated before, the UE may update the system message on CC1 in the state of CC1 activation, where The systemInfoValueTagl is the system message flag obtained when the UE last updated the system message on CC1.
需要说明的是, 因为连接态下 UE更新非主服务分量载波上进行数据通 信所需要的公共资源配置信息只需要获取 MIB, SIB1和 SIB2,与其他***信 息块无关, 因此优化的, 服务基站可以在 SIB1 中增加一个表征 MIB, SIB1
或 SIB2是否改变的标志, 为描述方便, 本发明专利称为基本***消息标志。 相应的,服务基站在 S301和 S303中发送的标志为 CC1在两个时间点上的基 本***消息标志, UE通过比较保存在本地的基本***消息标志和在激活指示 中接收到的基本***消息标志, 判断是否需要更新 CC1上的***消息, 判断 依据同上述根据***消息标志的判断。 It should be noted that, because the public resource configuration information required for the UE to update the non-primary service component carrier for data communication in the connected state only needs to acquire the MIB, SIB1 and SIB2, and is independent of other system information blocks, so the optimized service base station can Add a characterizing MIB to SIB1, SIB1 Or the flag of whether SIB2 changes, for convenience of description, the patent of the present invention is called a basic system message flag. Correspondingly, the flag sent by the serving base station in S301 and S303 is the basic system message flag of CC1 at two time points, and the UE compares the basic system message flag stored locally and the basic system message flag received in the activation indication. , judging whether it is necessary to update the system message on CC1, and judging according to the above judgment according to the system message flag.
还需要说明的, 按照现有技术, UE读取并保存***消息超过 3个小时, 所保存的***消息将自动失效, 因此, 本实施例中, 如果 UE在 S303接收到 ***消息标志时本地保存的***消息(公共资源配置信息)已经失效, 则 UE 不用对比 stemInfoValueTag2与 systemlnfoValueTagl ,直接读取 CC1上的*** 消息。 It should be noted that, according to the prior art, if the UE reads and saves the system message for more than 3 hours, the saved system message will be automatically invalidated. Therefore, in this embodiment, if the UE receives the system message flag in S303, it is saved locally. The system message (common resource configuration information) has expired, and the UE does not need to compare stemInfoValueTag2 with systemlnfoValueTagl to directly read the system message on CC1.
进一步优化的, 如实施例一所述, 因为 MIB中的相关信息, SIB1中的调 度信息一般很少改变, 上述基本***消息标志还可以进一步的仅是表征 SIB2 是否改变的标志。 Further optimized, as described in the first embodiment, because the information in the MIB generally has little change in the scheduling information in the MIB, the basic system message flag may further be only a flag indicating whether the SIB2 changes.
5305、 UE读取 CC1上的***消息 MIB, SIB1和 SIB2, 或者根据 S304 所述的优化方法, UE读取 CC1上的 SIB2。 5305. The UE reads the system messages MIB, SIB1, and SIB2 on CC1, or according to the optimization method described in S304, the UE reads SIB2 on CC1.
5306、 UE向服务基站反馈激活完成指示。 5306. The UE feeds back an activation completion indication to the serving base station.
如果 UE在***规定的时间内成功接收并读取到了 CC1上的***消息, 则 UE向服务基站反馈激活完成指示,该激活完成指示中指示 UE成功接收到 了 CC1上的***消息。 If the UE successfully receives and reads the system message on CC1 within the time specified by the system, the UE feeds back the activation completion indication to the serving base station, where the activation completion indication indicates that the UE successfully received the system message on CC1.
如果 UE在***规定的时间内未成功接收到 CC1上的***消息, 则 UE 在上述激活完成指示中通知服务基站 UE未成功接收到 CC1上的***消息, 或者如果服务基站在 S302中激活了多个分量载波, 则 UE在激活完成指示中 通知服务基站 UE成功接收到***消息的分量载波信息,或 UE未成功接收到 ***消息的分量载波信息, 或 UE成功接收到***消息的分量载波信息及未 成功接收到***消息的分量载波信息。 If the UE does not successfully receive the system message on CC1 within the time specified by the system, the UE notifies the serving base station that the UE does not successfully receive the system message on CC1 in the above activation completion indication, or if the serving base station activates more in S302. The component carrier, the UE notifies the serving base station UE that the component carrier information of the system message is successfully received in the activation completion indication, or the component carrier information that the UE does not successfully receive the system message, or the component carrier information that the UE successfully receives the system message and The component carrier information of the system message was not successfully received.
实施例三 Embodiment 3
用户设备 UE为具有载波聚合能力的 LTE-A UE, 以 FDD为例, UE当前 工作在两个分量载波上, 分量载波 1 CC1 ( DL fl , UL fl' )和分量载波 2 CC2
( DL f2, UL f2' )。 其中分量载波 2为该 UE的主服务分量载波; 分量载波 1 为非主服务分量载波且已激活。 The user equipment UE is an LTE-A UE with carrier aggregation capability. Taking FDD as an example, the UE currently works on two component carriers, component carrier 1 CC1 (DL fl , UL fl' ) and component carrier 2 CC2 (DL f2, UL f2'). Where component carrier 2 is the primary serving component carrier of the UE; component carrier 1 is a non-primary serving component carrier and is activated.
CC2为该 UE的主服务分量载波 , UE在 CC2上通过监听服务基站在 CC2 上发送的寻呼消息, 或者周期性检测 CC2上的 SIB1进行 CC2上***消息的 更新, 即 UE根据寻呼消息中是否指示***消息改变或者通过对比新接收到 的 SIB1中的 systemlnfoValueTag与 UE本地保存的原来接收到的 SIB1 中的 systemlnfoValueTag值, 判断是否需要更新服务小区的***消息。 The CC2 is the primary serving component carrier of the UE. The UE listens to the paging message sent by the serving base station on the CC2 on the CC2, or periodically detects the SIB1 on the CC2 to update the system message on the CC2, that is, the UE according to the paging message. Whether to indicate the system message change or to compare whether the systemInfofoValueTag in the newly received SIB1 and the systemInfofoValueTag value in the originally received SIB1 saved locally by the UE determine whether the system message of the serving cell needs to be updated.
UE釆用实施例一所述的方法更新 CC1上的***消息, 服务基站在 CC1 被成功去激活时记录 UE当前在 CC1上的***消息标志, 然后 UE不再更新 CC1上的***消息直到 CC1再次被服务基站激活, 具体流程如图 4所示: The UE updates the system message on CC1 by using the method described in Embodiment 1, and the serving base station records the system message flag of the UE currently on CC1 when CC1 is successfully deactivated, and then the UE does not update the system message on CC1 until CC1 again. Activated by the serving base station, the specific process is shown in Figure 4:
5401、 UE以实施例一所述方法更新 CC1上的***消息。 5401. The UE updates the system message on the CC1 by using the method in Embodiment 1.
本实施例中假设 UE在 CC1激活状态最后一次更新***消息时从 SIB1 中所获取到的***消息标志为 systemlnfoValueTagl。 In this embodiment, it is assumed that the system message flag acquired by the UE from SIB1 when the UE first updates the system message in the CC1 activation state is systemlnfoValueTagl.
同实施例二,优化的,服务基站可以在 SIB1中增加一个表征 MIB, SIB1 或 SIB2是否改变的基本***消息标志; 进一步优化的, 该基本***消息标志 还可以是仅表征 SIB2是否改变的基本***消息标志。 In the second embodiment, the serving base station may add a basic system message flag indicating whether the MIB, SIB1 or SIB2 is changed in the SIB1; further optimized, the basic system message flag may also be a basic system that only indicates whether the SIB2 is changed. Message sign.
5402、 服务基站去激活 CC1。 5402. The serving base station deactivates CC1.
因业务流量下降,或者 CC1信号质量恶化等原因,服务基站去激活 CC1。 The serving base station deactivates CC1 due to a decrease in traffic, or a deterioration in CC1 signal quality.
5403、 UE按照 S402的指示去激活 CC1后, 向服务基站反馈去激活完成 指示。 S403: After deactivating CC1 according to the instruction of S402, the UE feeds back a deactivation completion indication to the serving base station.
服务基站接收到 UE的去激活完成指示后, 记录 UE当前在 CC1上的系 统消息标志 (或者优化的为基本***消息标志) , 即 UE在 CC1激活状态最 后一次更新 CC1上的***消息时的***消息标志(或者优化的为基本***消 息标志 ) 。 After receiving the deactivation completion indication of the UE, the serving base station records the system message flag currently being used by the UE on CC1 (or optimized as the basic system message flag), that is, the system when the UE last updates the system message on CC1 in the CC1 activation state. Message flag (or optimized for basic system message flags).
5404、 UE在 CC1被服务基站去激活到 CC1再次被服务基站激活之间, 不更新 CC1上的***消息, 即 UE不监听 CC1上的寻呼消息, 也不周期性的 检测 CC1上的 SIB1。 5404. The UE does not update the system message on CC1 when CC1 is deactivated by the serving base station to be activated by the serving base station, that is, the UE does not monitor the paging message on CC1, and does not periodically detect SIB1 on CC1.
因为 CC1处于非激活状态,UE和服务基站并不在 CC1上进行业务传输, 因此 UE不需要更新 CC1上的***消息。
5405、 服务基站根据业务需要再次激活 CC1。 Since CC1 is in an inactive state, the UE and the serving base station do not perform traffic transmission on CC1, so the UE does not need to update the system message on CC1. 5405. The serving base station activates CC1 again according to the service requirement.
服务基站激活 CC1时,根据当前 CC1上的***消息标志或者基本***消 息标志 (为描述方便, 本实施例以 systemInfoValueTag2标识) , 以及 S403 所记录的***消息标志或基本***消息标志, 判断 UE所保存的 CC1上的系 统消息 (公共资源配置 ) 是否需要更新。 具体判断依据为如果 systemlnfoValueTagl 与 systemInfoValueTag2 相等, 则不需要更新; 如果 systemlnfoValueTagl与 systemInfoValueTag2不相等, 则需要更新。 本实施例 systemlnfoValueTagl与 systemInfoValueTag2不相等, 因此服务基站在激活指 示中携带 CC1上需要更新的公共资源配置信息(即需要更新的***消息的信 息 ) , 或者服务基站在激活指示中指示 UE更新 CC1上的***消息。 When the serving base station activates CC1, it judges that the UE saves according to the system message flag or the basic system message flag on the current CC1 (for convenience of description, this system is identified by systemInfoValueTag2), and the system message flag or basic system message flag recorded by S403. Whether the system message (common resource configuration) on CC1 needs to be updated. The specific judgment is based on the fact that if systemlnfoValueTagl is equal to systemInfoValueTag2, no update is required; if systemlnfoValueTagl is not equal to systemInfoValueTag2, it needs to be updated. In this embodiment, the systemInfoFValueTagl is not equal to the systemInfoValueTag2, so the serving base station carries the common resource configuration information (that is, the information of the system message that needs to be updated) that needs to be updated on the CC1 in the activation indication, or the serving base station instructs the UE to update the CC1 in the activation indication. system information.
5406、 UE激活 CC1 , 向服务基站反馈激活完成指示。 5406. The UE activates CC1, and feeds back an activation completion indication to the serving base station.
本实施例以激活指示中携带需要更新的公共资源配置信息为例, UE可用 接收到的公共资源配置信息直接替换本地存储的公共资源配置信息。 如果是 指示 UE更新 CC1 上的***消息, 则 UE接收到激活指示后的行为同步骤 S305~S306。 For example, the public resource configuration information that needs to be updated in the activation indication is taken as an example, and the UE can directly replace the locally stored common resource configuration information by using the received common resource configuration information. If the UE is instructed to update the system message on CC1, the behavior of the UE after receiving the activation indication is the same as steps S305-S306.
