- Information block, at this time, PSIB1 no longer carries scheduling information, but system information related to a specific service.
- SIB For the case of using SIB: The transmission of SIB messages still uses the existing transmission mechanism.
- the system message scheduled by the SI-RNTI and the system message related to the specific service scheduled by the PSI-RNTI may have the same or different message structure definitions (ie, different ASN.1 codecs), specifically, After the SI-RNTI receives the system message, the UE performs decoding according to the message structure specified by the 3GPP protocol (defined according to the ASN.1 message structure). After receiving the system message related to the specific service through the PSI-RNTI, the UE performs codec according to the message structure of the specific service definition.

Description
一种特定业务相关***消息的收发方法及装置 Method and device for transmitting and receiving specific service related system messages
技术领域 Technical field
本发明涉及通信技术领域, 尤其涉及一种特定业务相关***信息的收发 方法及装置。 The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting and receiving information of a specific service-related system.
背景技术 Background technique
LTE ( Long Term Evolution, 长期演进) ***中, 需要广播的***信息分 为主信息块(Master Information Block, 简称 MIB )和***信息块(System Information Block, 简称 SIB ) , 其中主信息块中包含了 UE (用户设备或称终 端)接入所需要的最重要的信息(下行带宽、 PHICH (物理 HARQ指示信道) 信息以及 SFN(***帧号))。 在传输时,主信息块在 BCH( Broadcast Channel, 广播信道)中传输,其位置固定;而 SIB则被包含在 SI消息( System Information message ) 中在 DL-SCH ( Downlink Shared Channel, 下行共享信道) 中传输。 SIB与 SI消息的映射关系 (即每个 SIB包含在哪个 SI消息中) 由 SIB1中的 调度信息列表( Scheduling Info List )给出。 每个 SIB只能被包含在一个 SI消 息中, 如果多个 SIB有相同的周期, 那么这些 SIB可以被包含在同一个 SI消 息中; 同时, 也可以有多个周期相同的 SI消息同时存在。 在 SIB 中, SIB1 的传输釆用固定周期, 其周期是 80ms, 并在所有满足 SFN mod 2 =0的无线 帧的第 5子帧重复。 其他 SI消息也是周期性的在时域窗口 (Si-Window ) 中 传输, 每个 SI消息都有自己的 SI- Window , 且不同 SI消息的 SI- Window不 会重叠。在 1个 SI- Window内,只有对应的 SI消息会被传输。在一个 SI- Window 内, 一个 SI 消息可以发送多次。 终端使用***信息无线网络临时标识 (System Information Radio Network Temporary Identifier, 简称 SI-RNTI)接收 PDCCH ( Physical Downlink Control Channel, 物理下行控制信道)获取***消 息的资源配置, 其中 SI-RNTI取值固定为 FFFF。 In the LTE (Long Term Evolution) system, the system information to be broadcasted is divided into a Master Information Block (MIB) and a System Information Block (SIB), where the main information block is included. The most important information (downstream bandwidth, PHICH (Physical HARQ Indicator Channel) information, and SFN (System Frame Number)) required by the UE (User Equipment or Terminal) to access. During transmission, the primary information block is transmitted in the BCH (Broadcast Channel), and its location is fixed; and the SIB is included in the SI Message (System Information Message) in the DL-SCH (Downlink Shared Channel). In transit. The mapping relationship between the SIB and the SI message (i.e., in which SI message each SIB is included) is given by the Scheduling Info List in SIB1. Each SIB can only be included in one SI message. If multiple SIBs have the same period, then these SIBs can be included in the same SI message. At the same time, multiple SI messages with the same period can exist at the same time. In SIB, the transmission of SIB1 uses a fixed period with a period of 80 ms and repeats in the 5th subframe of all radio frames satisfying SFN mod 2 =0. Other SI messages are also periodically transmitted in the time domain window (Si-Window). Each SI message has its own SI-Window, and the SI-Window of different SI messages does not overlap. Within a SI-Window, only the corresponding SI messages are transmitted. Within an SI-Window, an SI message can be sent multiple times. The terminal uses the System Information Radio Network Temporary Identifier (SI-RNTI) to receive the PDCCH (Physical Downlink Control Channel) to obtain the resource configuration of the system message, where the value of the SI-RNTI is fixed to FFFF. .
在基于 LTE的宽带无线集群通信***中, 要实现集群通信, 需要实现集 群***参数的广播。 本申请的发明人发现, 目前 LTE***消息中并没有包含 集群信息, 而如果直接在 3GPP框架下的 LTE现有***消息中添加字段, 可
能会造成兼容性问题, 使得非集群终端无法接入集群网络。 发明内容 In the LTE-based broadband wireless trunking communication system, in order to implement cluster communication, it is necessary to implement broadcast of cluster system parameters. The inventor of the present application finds that the current LTE system message does not include the cluster information, and if the field is added directly to the LTE existing system message in the 3GPP framework, Can cause compatibility problems, making non-clustered terminals unable to access the cluster network.

下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。 Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.
实施例 1 Example 1
本实施例说明了特定业务相关***消息的接收方法, 如图 1所示, 包括 以下步骤: This embodiment describes a method for receiving a service-related system message, as shown in FIG. 1, including the following steps:
步骤 101 , 用户设备 ( UE )通过 SI-RNTI接收***消息; Step 101: A user equipment (UE) receives a system message by using an SI-RNTI.
本步骤中的 UE可以是支持特定业务的 UE,也可以是不支持特定业务的 UE, 对于不支持特定业务的 UE, 其接收***消息后, 按照现有技术执行后 续流程, 对于支持特定业务的 UE, 其接收***消息后, 执行步骤 102。 The UE in this step may be a UE that supports a specific service, or a UE that does not support a specific service. For a UE that does not support a specific service, after receiving the system message, the UE performs the subsequent process according to the existing technology, and supports the specific service. After receiving the system message, the UE performs step 102.
UE通过 SI-RNTI接收***消息,包括: UE监听 PDCCH,并判断 PDCCH 上是否有针对 SI-RNTI 的授权(即 PDCCH上物理层信令的 CRC是否用 SI-RNTI进行加扰 ( scrambled ) ) , 如果有针对 SI-RNTI的授权, 则 UE在针 对 SI-RNTI授权的物理资源 (即釆用 SI-RNTI加扰的 PDCCH物理层信令中 调度的物理层资源)接收***消息。 The UE receives the system message by using the SI-RNTI, and the method includes: the UE monitors the PDCCH, and determines whether there is an authorization for the SI-RNTI on the PDCCH (that is, whether the CRC of the physical layer signaling on the PDCCH is scrambled by the SI-RNTI), If there is an authorization for the SI-RNTI, the UE receives the system message for the physical resource authorized for the SI-RNTI (ie, the physical layer resource scheduled in the PDCCH physical layer signaling scrambled by the SI-RNTI).
步骤 102,支持特定业务的 UE通过所述***消息判断当前小区是否支持 特定业务, 若所述 UE判断当前小区支持所述特定业务, 则接收与所述特定 业务相关的***消息。 Step 102: The UE supporting the specific service determines whether the current cell supports a specific service by using the system message, and if the UE determines that the current cell supports the specific service, receives a system message related to the specific service.
上述特定业务(或称为预定业务) 包括但不限于集群通信业务。 The above specific services (or referred to as scheduled services) include, but are not limited to, trunked communication services.
支持特定业务的 UE利用***消息判断当前小区是否支持特定业务的一 种方法包括: 支持特定业务的 UE通过***消息中 IE ( Information Element,
信元)的取值来判断, 当 IE的取值满足预先约定的规则时, 认定当前小区支 持特定业务。 上述 IE包括但不限于下列 IE中的一个或多个: A method for a UE supporting a specific service to determine whether a current cell supports a specific service by using a system message includes: a UE supporting a specific service passes an IE (Information Element, in a system message) The value of the cell is judged. When the value of the IE satisfies the pre-agreed rule, it is determined that the current cell supports a specific service. The above IE includes but is not limited to one or more of the following IEs:
SIB1中的 "csg-Identity (闭合用户组标识)" IE; SIB1中的 "csg-Indication (闭合用户组指示) " IE; SIB1中的 "PLMN-Identity ( PLMN标识) " IE; SIB9中的 "hnb-Name (家庭基站名) " IE。 "csg-Identity" IE in SIB1; "csg-Indication" in IE1; IE; "PLMN-Identity" in SIB1 IE; "in SIB9" hnb-Name (home base station name) "IE.
所述预先约定的规则包括: 所述 IE取值的全部或部分与预设值相同, 其 中预设值为固定值或为可配置值。 IE取值的部分与预设值相同,是指 IE的部 分字段取值与预设值相同, 该部分字段可以是固定字段或非固定字段。 预设 值为固定值的一种可能的情况是, 该固定值由协议规定。 所述预设值为可配 置值的一种可能的情况是, 该可配置值是 UE以前保存的, 但是可以通过其 他手段(例如, 非接入层信令或者运营商统一在 SIM卡中配置等方式)动态 修改。 The pre-agreed rule includes: all or part of the value of the IE is the same as a preset value, where the preset value is a fixed value or a configurable value. The value of the IE is the same as the preset value. It means that the value of the IE part field is the same as the preset value. The part field can be a fixed field or a non-fixed field. A possible case where the preset value is a fixed value is that the fixed value is specified by the protocol. A possible case where the preset value is a configurable value is that the configurable value is previously saved by the UE, but may be configured in the SIM card by other means (for example, non-access stratum signaling or carrier unified configuration in the SIM card) Etc.) Dynamic modification.
若终端判断当前小区支持所述特定业务, 接收与特定业务相关的***消 息时,使用预先约定的 RNTK本文中称为 Particular SI-RNTI,简称 PSI-RNTI ), 该 PSI-RNTI 是专用于调度特定业务的一种特殊的 RNTI, 其取值可以与 SI-RNTI的取值相同或不同 (注: 当 PSI-RNTI与 SI-RNTI取值相同时 , 通过 PSI-RNTL SI-RNTI调度的***消息结构定义也需要相同或者兼容(及即特 定业务的***消息是通过在原有***消息结构上进行兼容性扩展来携带 的) ) 。 当小区中同时有多个特定业务时, 不同特定业务可以共用一个 PSI-RNTI, 或者不同特定业务可以使用不同的 PSI-RNTI。 PSI-RNTI 的一种 实现为: 长 16bit, 取值区间为 [0001 , FFFC] ( 16进制) 。 If the terminal determines that the current cell supports the specific service and receives a system message related to the specific service, the pre-agreed RNTK is used herein as a Particular SI-RNTI (PSI-RNTI for short), and the PSI-RNTI is dedicated to scheduling specific A special RNTI of the service, which may be the same as or different from the value of the SI-RNTI. (Note: The system message structure scheduled by the PSI-RNTL SI-RNTI when the PSI-RNTI and the SI-RNTI are the same value. The definitions also need to be the same or compatible (and that system messages for specific services are carried by compatibility extensions on the original system message structure). When there are multiple specific services in a cell, different specific services may share one PSI-RNTI, or different specific services may use different PSI-RNTIs. One implementation of PSI-RNTI is: 16 bits long, with a range of [0001, FFFC] (hexadecimal).
上述步骤 102中, UE通过 PSI-RNTI接收与特定业务相关的***消息, 包括: UE监听 PDCCH, 并判断 PDCCH上是否有针对 PSI-RNTI的授权(即 PDCCH上的物理层信令的 CRC是否利用 PSI-RNTI进行加扰( scrambled ) ) , 如果有针对 PSI-RNTI的授权, 则 UE在针对 PSI-RNTI授权的物理资源接收 与特定业务相关的***消息。 In the foregoing step 102, the UE receives the system message related to the specific service by using the PSI-RNTI, including: the UE monitors the PDCCH, and determines whether there is an authorization for the PSI-RNTI on the PDCCH (that is, whether the CRC of the physical layer signaling on the PDCCH is utilized. The PSI-RNTI performs scrambling. If there is authorization for the PSI-RNTI, the UE receives a system message related to the specific service at the physical resource authorized for the PSI-RNTI.
支持特定业务的 UE在首次釆用 PSI-RNTI接收与特定业务相关的***消 息后,还可定期通过 SI-RNTI接收***消息,通过 PSI-RNTI接收与特定业务 相关的***消息。 可以看出, UE釆用 PSI-RNTI接收与特定业务相关的***
消息的同时, 仍然可以釆用 SI-RNTI接收***消息, 不同业务***消息的接 收互不影响, 有效避免了兼容性问题的发生。 After receiving the system information related to a specific service for the first time, the UE supporting the specific service may periodically receive the system message through the SI-RNTI, and receive the system message related to the specific service through the PSI-RNTI. It can be seen that the UE uses the PSI-RNTI to receive a system related to a specific service. At the same time, the SI-RNTI can still receive system messages, and the reception of messages of different service systems does not affect each other, effectively avoiding the occurrence of compatibility problems.
与特定业务相关的***消息可以由一个或多个特定***信息块组成(例 如 PSIB1、 PSIB2、 PSIB3、 PSIB4等) ; 也可以由一个或多个 SIB组成, 该 些 SIB可以包括现有已使用的 SIB (如 SIB2、 SIB3等 )或包括预留的 SIB携 带 (如 SIB19、 SIB20等) 。 对于釆用多个特定***信息块携带的情况: A system message related to a specific service may be composed of one or more specific system information blocks (for example, PSIB1, PSIB2, PSIB3, PSIB4, etc.); or may be composed of one or more SIBs, which may include existing used SIB (such as SIB2, SIB3, etc.) or including reserved SIBs (such as SIB19, SIB20, etc.). For the case of using multiple specific system information blocks:
一种接收与特定业务相关的***消息的方式是: UE先在 PSIB1的传输周 期内接收该 PSIB1 , 从 PSIB1 中获取其他特定***信息块的调度信息 (除调 度信息外, PSIB1 还可携带其他特定业务相关信息) , 根据获取到的调度信 息获取其他特定***信息块。 A method for receiving a system message related to a specific service is: the UE first receives the PSIB1 in a transmission period of the PSIB1, and acquires scheduling information of other specific system information blocks from the PSIB1 (in addition to the scheduling information, the PSIB1 may carry other specifics. Business related information), according to the obtained scheduling information to obtain other specific system information blocks.
其中, PSIB1 的传输釆用固定周期, 并在满足一定条件的子帧重复。 例 如: 一定条件可以是: SFN mod 8 =X的无线帧的第 5个子帧, 其中 X取值事 先约定, 可以是 0到 7间的整数。 UE在读取到 PSIB1后, 根据其中的调度信 息获取其他信息块。 Among them, the transmission of PSIB1 uses a fixed period and repeats in a subframe that satisfies certain conditions. For example: A certain condition may be: SFN mod 8 = the 5th subframe of the radio frame of X, where X is a predetermined value, and may be an integer between 0 and 7. After reading the PSIB1, the UE acquires other information blocks according to the scheduling information therein.
另一种接收与特定业务相关的***消息的方式是: PSIB2 或 PIB3 或 PSIB4也釆用类似 PSIB1的固定传输时刻方式进行发送, 即 UE在各个特定 ***信息块对应的传输周期内接收各个特定***信息块, 此时 PSIB1中就不 再携带调度信息 , 而是与特定业务相关的***信息。 Another way to receive system messages related to a specific service is: PSIB2 or PIB3 or PSIB4 is also transmitted in a fixed transmission time mode similar to PSIB1, that is, the UE receives each specific system in a transmission cycle corresponding to each specific system information block. Information block, at this time, PSIB1 no longer carries scheduling information, but system information related to a specific service.
对于釆用 SIB携带的情况: SIB消息的传输仍沿用现有传输机制。 For the case of using SIB: The transmission of SIB messages still uses the existing transmission mechanism.
所述通过 SI-RNTI调度的***消息和所述通过 PSI-RNTI调度的特定业务 相关的***消息可以拥有相同或不同的消息结构定义(即不同的 ASN.1编解 码) , 具体地, 在通过 SI-RNTI接收***消息后, UE按照 3GPP协议规定的 消息结构 (依据 ASN.1消息结构定义)进行解码。 在通过 PSI-RNTI接收与 特定业务相关的***消息后, UE按照特定业务定义的消息结构进行编解码。 其中, 特定业务定义的消息结构可以与 3GPP定义的消息结构完全相同、 部 分相同或完全不同。 The system message scheduled by the SI-RNTI and the system message related to the specific service scheduled by the PSI-RNTI may have the same or different message structure definitions (ie, different ASN.1 codecs), specifically, After the SI-RNTI receives the system message, the UE performs decoding according to the message structure specified by the 3GPP protocol (defined according to the ASN.1 message structure). After receiving the system message related to the specific service through the PSI-RNTI, the UE performs codec according to the message structure of the specific service definition. The message structure of a specific service definition may be identical to, identical to, or completely different from the message structure defined by the 3GPP.
在一个优选实施例中,在判断当前小区支持特定业务后, UE还可以进一
步利用***信息中的内容判断自己是否有权使用当前小区的特定业务。 UE可 以先判断自己是否有权使用当前小区的特定业务, 当 UE判断自己有权使用 当前小区的特定业务后, 再接收所述特定业务相关的***信息; 或者, UE也 可以先接收特定业务相关的***信息, 然后再判断自己是否有权使用当前小 区的特定业务。 In a preferred embodiment, after determining that the current cell supports a specific service, the UE may further enter a Steps use the content in the system information to determine whether they have the right to use the specific service of the current cell. The UE may first determine whether it has the right to use the specific service of the current cell. When the UE determines that it has the right to use the specific service of the current cell, the UE may receive the system information related to the specific service. Alternatively, the UE may also receive the specific service related information. System information, and then determine whether they have access to the specific business of the current cell.
具体地, 可以通过***消息中用于判断是否有权使用当前小区特定业务 IE来进行判断,判断该 IE的取值是否满足预先约定的规则。具体包括但不限 于下列 IE中的一个或多个: Specifically, the system message may be used to determine whether the current cell-specific service IE is used to determine whether the value of the IE satisfies the pre-agreed rule. This includes but is not limited to one or more of the following IEs:
SIB1中的 "csg-Identity" IE; SIB1中的 "csg-Indication" IE; SIB1中的 "PLMN-Identity" IE; SIB9中的 "hnb-Name" IE。 "csg-Identity" IE in SIB1; "csg-Indication" IE in SIB1; "PLMN-Identity" IE in SIB1; "hnb-Name" IE in SIB9.
此处预先约定的规则同上, 包括: 所述 IE取值的全部或部分与预设值相 同, 其中预设值为固定值或为可配置值。 The pre-agreed rules are the same as above, and include: all or part of the value of the IE is the same as the preset value, where the preset value is a fixed value or a configurable value.
此处判断 UE是否有权使用当前小区特定业务所使用的 IE范围, 与判断 当前小区是否支持特定业务的所使用的 IE范围相同, 优选地, 两判断选择不 同的 IE和 /或规则。 Here, it is judged whether the UE has the right to use the IE range used by the current cell-specific service, and is the same as the IE range used to determine whether the current cell supports a specific service. Preferably, the two judgments select different IEs and/or rules.

己保存的白列表 "whitelist" 中, 如果 UE同时满足上述两个条件, 执行步骤 503 , 任一条件不满足, 则 UE不使用 PSI-RNTI读取集群业务相关***信息; 步骤 503、 UE认为此小区支持集群业务并开始使用 PSI-RNTI (取值为 FFF0 )接收集群相关的***消息; Step 502: After reading the system message, the UE determines whether the value of the IE "hnb-Name" in the SIB9 is "cluster network", and whether the IE "csg-Identity" in the SIB1 is included in the UE. In the saved white list "whitelist", if the UE satisfies the above two conditions, and performs step 503, if any of the conditions are not satisfied, the UE does not use the PSI-RNTI to read the cluster service related system information; Step 503: The UE considers this The cell supports the cluster service and starts to receive the cluster related system message by using the PSI-RNTI (which is a value of FFF0);
在本示例中, UE利用 PSI-RNTI接收到的***消息与 SI-RNTI接收到的 ***消息结构不同,因此 UE利用不同的解码函数对不同 RNTI上收到的消息 进行 ASN.1编解码。 In this example, the system message received by the UE using the PSI-RNTI is different from the system message structure received by the SI-RNTI, so the UE performs ASN.1 codec on the messages received on different RNTIs by using different decoding functions.
其中, 判断 SIB9中的 IE "hnb-Name" 取值时, 可能方式还有: 判断 "hnb-Name"字符串中前 8个 byte对应的信息是否是 "集群网络"; 判断 "hnb-Name" 字符串中是否包含了 "集群网络" 4个字; When judging the value of the IE "hnb-Name" in SIB9, the possible ways are as follows: Determine whether the information corresponding to the first 8 bytes in the "hnb-Name" string is "cluster network"; judge "hnb-Name" Whether the string contains "cluster network" 4 words;

应用示例 2
如图 6所示, 包括以下步骤: Application example 2 As shown in Figure 6, the following steps are included:
步骤 601、 UE在小区中使用 SI-RNTI接收***消息, 此***信息釆用 3GPP协议规定的方式进行编码; Step 601: The UE receives the system message by using the SI-RNTI in the cell, where the system information is encoded by using a method specified by the 3GPP protocol.
步骤 602、 UE在读取到***消息后,判断 SIB 1中携带的 "PLMN-Identity" 中是否有满足预先约定的取值条件的 (例如全 0、 全 1或某事先约定的特殊 取值等) , 如果不满足, 则 UE认为此小区不支持集群业务, 执行步骤 604, 如果满足执行步骤 603; Step 602: After reading the system message, the UE determines whether the "PLMN-Identity" carried in the SIB 1 meets the pre-agreed value condition (for example, all 0s, all 1s, or a predetermined special value, etc.) If not satisfied, the UE considers that the cell does not support the cluster service, and performs step 604, if the step 603 is satisfied;
步骤 603、 如果 UE判断***消息满足上述条件, 则 UE判断此小区支持 集群业务, 并进一步判断 SIB1 中的 IE "csg-Indication" 取值是否为 "真" ( True ) ; 若取值为 "True" , 则执行步骤 605, 否则执行步骤 604; Step 603: If the UE determines that the system message satisfies the foregoing condition, the UE determines that the cell supports the cluster service, and further determines whether the value of the IE "csg-Indication" in the SIB1 is "true" (True); if the value is "True" " , then step 605 is performed, otherwise step 604 is performed;
步骤 604、 UE不使用 PSI-RNTI读取集群业务相关***信息; Step 604: The UE does not use the PSI-RNTI to read cluster service related system information.
步骤 605、 进一步判断 IE "csg-Identity" 是否包含在 UE 自己保存的白 列表 "whitelist" 中, 若不包含, 则 UE认为无权使用此小区的集群服务, 执 行步骤 604; 如果包含, 则进入步骤 606; Step 605, further determining whether the IE "csg-Identity" is included in the white list "whitelist" saved by the UE. If not, the UE considers that it does not have the right to use the cluster service of the cell, and performs step 604; if included, enters Step 606;
步骤 606、 UE认为有权使用此小区的集群服务并开始使用 SI-RNTI接收 集群相关的***消息 (即 PSI-RNTI取值与 SI-RNTI取值相同) 。 Step 606: The UE considers that it has the right to use the cluster service of the cell and starts to use the SI-RNTI to receive the cluster-related system message (that is, the value of the PSI-RNTI is the same as the value of the SI-RNTI).
UE在使用 SI-RNTI获取集群***消息时,首先在固定时间点获取 PSIB1 ( PSIB1的传输时刻事先由标准约定, 其釆用固定周期 80ms, 并在满足 SFN mod 8 =1的无线帧的第 5个子帧重复) ; 并根据 PSIB1中的调度信息获取 PSIB2、 PSIB3等***信息块。 When acquiring the cluster system message by using the SI-RNTI, the UE first acquires the PSIB1 at a fixed time point (the transmission time of the PSIB1 is previously agreed by the standard, and the fixed period is 80 ms, and the fifth of the radio frames satisfying the SFN mod 8 =1 The subframes are repeated; and the system information blocks such as PSIB2 and PSIB3 are obtained according to the scheduling information in PSIB1.
注: 此时网络侧需保证 PSIB与传统 SIB的调度时刻不重叠。 Note: At this time, the network side needs to ensure that the scheduling time of the PSIB and the traditional SIB does not overlap.
注: UE利用 PSI-RNTI接收到的***消息与 SI-RNTI接收到的***消息 结构不同, 因此 UE 利用不同的解码函数对不同 RNTI上收到的消息进行 ASN.1编解码。 Note: The system message received by the UE using the PSI-RNTI is different from the system message structure received by the SI-RNTI. Therefore, the UE uses different decoding functions to perform ASN.1 encoding and decoding on messages received on different RNTIs.
注: UE通过 "csg-Identity" 、 "csg-Indication" 判断是否有权使用所述 小区与 UE通过判断本小区是否支持集群业务没有明确的先后顺序; UE可以 先判断是否有权使用本小区, 再判断本小区是否支持集群业务, 并当两者同 时满足时再监听 PSI-RNTI获取集群***消息。
其中, 集群业务相关的***信息块包括 PISB1、 PSIB2。 其中 PSIB1的传 输釆用固定周期 80ms, 并在满足 SFN mod 8 =1的无线帧的第 5个子帧重复。 而 PSIB2也釆用固定周期 80ms, 并在满足 SFN mod 8 =3的无线帧的第 5个 子帧重复。 Note: The UE determines whether it has the right to use the cell and the UE through the "csg-Identity" and the "csg-Indication" to determine whether the cell supports the cluster service. The UE may first determine whether it has the right to use the cell. Then, it is determined whether the cell supports the cluster service, and then listens to the PSI-RNTI to obtain the cluster system message when both are satisfied. Among them, the system information block related to the cluster service includes PISB1 and PSIB2. The transmission of PSIB1 is fixed for a period of 80 ms, and is repeated in the fifth subframe of the radio frame satisfying SFN mod 8 =1. PSIB2 also uses a fixed period of 80 ms and repeats in the 5th subframe of the radio frame satisfying SFN mod 8 = 3.
其中, ***消息中用于判断是否支持特定业务的 IE 不仅限于 The IE used in the system message to determine whether to support a specific service is not limited to
