Abstract

本发明提出一种集群组呼盲检能力处理方法，该方法包括以下步骤：终端处于无线资源控制连接（RRC-Connected）状态且有集群组呼被叫业务时（101），向基站指示其集群标识和物理下行控制信道（PDCCH）盲检能力（102）。

Description

集群组呼盲检能力处理方法、装置和系统 技术领域
本发明涉及无线通信领域，尤其涉及一种集群组呼盲检能力处理方法、装置和系统。
发明背景
LTE系统增加集群功能后，对于终端来说，增加了一个集群业务。集群业务对应的空口标识为G-RNTI。对于PDCCH控制信道，如果把G-RNTI放在专用空间，则要求终端增加对G-RNTI的盲检，即要求增加终端的盲检次数，则对于只满足正常LTE业务所需盲检能力的终端，无法支持同时使用点对点业务和集群业务；如果把G-RNTI放在公共空间，则无需增加终端的盲检次数。协议规定PDCCH的CCE公共空间共有16个CCE资源(0～15)，而且其CCE分配粒度为4或者8。因此，对于将G-RNTI放在公共空间的方法，在小区中有大量组呼业务时，则会受限于公共空间，即可能会存在很多组呼业务由于其G-RNTI无法获得CCE资源而无法得到及时调度。
现有的技术手段是：如果当前小区的所述组呼业务中有UE在该下行TTI中有个体业务待调度，则发送端对所述组呼业务采用G-RNTI或SPS G-RNTI在公共空间进行调度，对所述UE的个体业务采用C-RNTI或SPS C-RNTI在专用空间进行调度；如果当前小区的所述组呼中的所有UE在该下行TTI中均没有个体业务待调度，则发送端对所述组呼业务采用G-RNTI或SPS G-RNTI在专用空间进行调度。
发明内容
本发明提出一种集群组呼盲检能力处理方法，该方法包括：
终端处于无线资源控制连接RRC_Connected状态且有集群组呼被叫业务时，所述终端向基站指示其集群标识和物理下行控制信道PDCCH盲检能力。
本发明还提出一种集群组呼盲检能力处理终端，所述终端包括：
指示模块，用于当终端处于无线资源控制连接RRC_Connected状态并且具有集群组呼被叫业务时，向基站指示所述终端的集群标识和物理下行控制信道PDCCH盲检能力。
本发明还提出一种集群组呼盲检能力处理方法，包括：
基站接收集群业务中处于无线资源控制连接RRC_Connected状态的终端上报的用于指示其集群标识和物理下行控制信道PDCCH盲检能力的消息；
确定所述集群业务以及所述终端的PDCCH盲检能力。

实施本发明的方式
本发明人在发明过程中发现现有技术存在如下缺陷：基站侧未对某组呼业务下各终端的PDCCH盲检能力进行识别就做出调度的判断，则对于集群组呼下各终端都支持G-RNTI的专用空间时，基站侧依然有可能会将集群组呼业务放在公共空间调度而导致组呼数量受限于公共空间的问题。
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组合。下面将参考附图并结合实施例来详细说明本发明。

以下实施例中，将分别从终端侧和基站侧详细描述本发明提出的方法。
实施例一
图1为本发明一个实施例所提出的方法在终端侧的处理流程框图。如图1所示，该方法包括以下步骤：
步骤101，确定终端处于RRC连接RRC_Connected状态且有集群组呼被叫业务。
步骤102，当终端处于RRC_Connected状态并且具有集群组呼被叫 业务时，终端向基站指示其集群标识和PDCCH盲检能力。
进一步地，把终端的PDCCH盲检能力分为低和高两档，PDCCH盲检能力为低表示终端支持在一个TTI下同时盲检C-RNTI在专用空间和G-RNTI在公共空间的能力；PDCCH盲检能力为高表示终端支持在一个TTI下同时盲检C-RNTI在专用空间和G-RNTI在专用空间的能力。如下表1所示：
表1终端PDCCH盲检能力及含义
终端盲检能力 含义
低 C-RNTI专用空间+G-RNTI公共空间
高 C-RNTI专用空间+G-RNTI专用空间
如果终端不同时满足处于RRC_Connected状态且有集群组呼被叫业务时，或者终端处于RRC空闲RRC_Idle状态时，不向基站上报其集群组呼被叫业务对应的G-RNTI。
进一步的，当终端处于RRC_Idle状态、有集群组呼被叫业务、且PDCCH盲检能力为低时，所述终端发起随机接入进入RRC_Connected状态。
以下说明两种方式来指示终端的集群组呼标识和PDCCH盲检能力，当然也不限于此。
方式一：通过C-RNTI MAC CE向基站上报终端的集群标识。
具体为：如果终端盲检能力为低，则通过C-RNTI MAC CE向基站上报G-RNTI；如果终端盲检能力为高，则不通过C-RNTI MAC CE向基站上报G-RNTI。
本实施例中，C-RNTI MAC CE的结构可以如图2所示，其中，C-RNTI占用16个比特。
方式二：通过P-ABILITY MAC CE向基站上报终端的集群标识和PDCCH盲检能力。
本实施例中，P-ABILITY MAC CE的结构可以如图3所示，其中，G-RNTI占用16个比特；PDCCH盲检能力用P字段来标识，可以占用1个比特，例如，用1表示PDCCH盲检能力低，用0表示PDCCH盲检能力高；剩余7个比特为保留位。当然，也不限于此。
现有LTE的UL-SCH信道的LCID列表如图4所示，包含自定义P-ABILITY的LCID列表如图5所示。其中，索引为11000时，对应的LCID即为P-ABILITY。
以上两种方式仅为示例，也可以采用其他方式，本发明并不限定于此。
实施例二
对应上述实施例，本发明提出的方法在基站侧的处理方法如图6所示，该方法包括以下步骤：
步骤601，基站接收集群业务中处于RRC_Connected状态的终端上报的用于指示其集群标识和PDCCH盲检能力的消息，确定所述集群业务以及所述终端的PDCCH盲检能力。
对应于上述实施例中终端侧的两种方式，基站侧的处理方式如下：
方式一：
基站侧小区接收到终端上报的C-RNTI MAC CE，并获得C-RNTI MAC CE中C-RNTI字段的值，表示为G，并判断G与该终端的C-RNTI是否相同，如果不同，则认为该终端处于G-RNTI为G的集群组呼被叫业务，且该终端的PDCCH盲检能力为低。
方式二：
基站侧小区接收到终端上报的P-ABILITY MAC CE，并获得P-ABILITY MAC CE中G-RNTI的值(表示为G)和P字段的值(表示为D)，则认为该终端处于G-RNTI为G的集群组呼被叫业务，并判断D。比如，D为1则认为该终端的PDCCH盲检能力为低；D为0则认为该终端的PDCCH盲检能力为高。当然也不限于此。P字段的内容可以根据系统实际情况设计，并不仅限于高低两个等级。
步骤602，基站收集集群组呼中各RRC_Connected状态的终端的PDCCH盲检能力，并动态确定该集群组呼的盲检能力。
具体为：当基站侧小区收集到的集群组呼中的各RRC_Connected状态的终端的盲检能力均为高时，则判断集群组呼的盲检能力为高；否则，判断集群组呼的盲检能力为低。
所述动态确定包括确定集群组呼的盲检能力，或者更新集群组呼的盲检能力。
步骤603，基站依据该集群组呼的盲检能力对该集群组呼业务进行调度。
具体为：当判断集群组呼的盲检能力为高时，则对该集群组呼业务所对应的G-RNTI放在专用空间进行调度；当判断当集群组呼的盲检能力为低时，则对该集群组呼业务所对应的G-RNTI放在公共空间进行调度。
进一步地，基站侧初始默认集群组呼下的所有终端(包括RRC_Connected状态的终端和RRC_Idle状态的终端)的盲检能力均为高。
本发明提出的方法：基站可以依据集群组呼中终端的PDCCH盲检能力来合理地调整组呼的G-RNTI的分配空间，以达到系统的组呼容量最大化。
本发明的上述方法实施例将通过以下两个实例进行具体描述。
实例一
令某基站的小区存在3个UE，分别为UE0～UE2，该小区存在一个集群被呼业务，其G-RNTI为15，对应的UE分别为UE0～UE2，其中，UE0和UE1均处于RRC_Connected状态，UE2处于RRC_Idle状态，令UE0的C-RNTI为5，UE1的C-RNTI为23。令UE0的PDCCH盲检能力为低，UE1和UE2的PDCCH盲检能力均为高。令终端通过C-RNTI MAC CE进行反馈，基站进行相应的接收和处理。
发射端：
UE0：
终端UE0处于RRC_Connected状态且有集群组呼被叫业务，其G-RNTI为15；UE0的PDCCH盲检能力为低，UE0通过C-RNTI MAC CE向基站侧小区上报UE0的集群组呼标识，具体为：UE0把G-RNTI为15装入C-RNTI MAC CE，并上报给基站侧小区。
UE1：
终端UE1处于RRC_Connected状态且有集群组呼被叫业务，其G-RNTI为15；UE1的PDCCH盲检能力为高，故UE1不通过C-RNTI MAC CE向基站侧小区上报UE1的集群组呼标识。
UE2：
终端UE2处于RRC_Idle状态，且盲检能力为高，故UE2不通过C-RNTI MAC CE向基站侧小区上报UE0的集群组呼标识。
此处，如果UE2的盲检能力为低，则UE2可以发起随机接入，进入RRC_Connected状态，上报自己的集群组呼标识。
接收端：基站侧小区
基站侧小区接收到终端UE0上报的C-RNTI MAC CE，并解出里面 的C-RNTI字段的值为15，并与UE0的C-RNTI为5进行比较，这两个值不相同，则认为该终端处于G-RNTI为15的集群组呼被叫业务，且该终端的PDCCH盲检能力为低。
基站侧小区未收到集群组呼被叫业务G-RNTI为15里的其余终端的C-RNTI MAC CE反馈，则默认为其余终端的PDCCH盲检能力均为高。
相应的，如果UE2的盲检能力为低，UE2可以发起随机接入，进入RRC_Connected状态，上报自己的集群组呼标识。此时基站侧小区可以收到UE2上报的相关信息。
进一步地，基站侧小区收集集群组呼中各RRC_Connected状态的终端的盲检能力，并确定或者更新该集群组呼的盲检能力。具体为：基站侧小区收集到G-RNTI为15的集群组呼被叫业务中的RRC_Connected状态的终端为UE0，其盲检能力为低，则判断集群组呼的盲检能力为低。
进一步地，基站侧小区依据该集群组呼的盲检能力对该集群组呼业务进行调度。具体为：基站侧小区对判断当集群组呼的盲检能力为低时，则对该集群组呼业务所对应的G-RNTI放在公共空间进行调度。
实例二
令某基站的小区存在4个UE，分别为UE0～UE3，该小区存在一个集群被呼业务，其G-RNTI为31，对应的UE分别为UE0～UE3，其中，UE1、UE2和UE3均处于RRC_Connected状态，UE0处于RRC_Idle状态，令UE1的C-RNTI为16，UE2的C-RNTI为24，UE3的C-RNTI为35。令UE0～UE3的PDCCH盲检能力均为高。令终端通过方式二(即P-ABILITY MAC CE)进行反馈，基站通过方式二进行接收和处理。
发射端：
UE0：
终端UE0处于RRC_Idle状态，故UE0不通过P-ABILITY MAC CE 向基站侧小区上报UE0的集群组呼标识和PDCCH盲检能力。
UE1：
终端UE1处于RRC_Connected状态且有集群组呼被叫业务，其G-RNTI为31；UE1的PDCCH盲检能力为高，故UE1通过P-ABILITY MAC CE向基站侧小区上报UE1的集群组呼标识和PDCCH盲检能力。P-ABILITY MAC CE中各字段填写的值为：G-RNTI字段填写31，P字段填写0，Reserved字段填写随机值。
UE2：
终端UE2处于RRC_Connected状态且有集群组呼被叫业务，其G-RNTI为31；UE2的PDCCH盲检能力为高，故UE2通过P-ABILITY MAC CE向基站侧小区上报UE2的集群组呼标识和PDCCH盲检能力。P-ABILITY MAC CE中各字段填写的值为：G-RNTI字段填写31，P字段填写0，Reserved字段填写随机值。
UE3：
终端UE3处于RRC_Connected状态且有集群组呼被叫业务，其G-RNTI为31；UE3的PDCCH盲检能力为高，故UE3通过P-ABILITY MAC CE向基站侧小区上报UE3的集群组呼标识和PDCCH盲检能力。P-ABILITY MAC CE中各字段填写的值为：G-RNTI字段填写31，P字段填写0，Reserved字段填写随机值。
接收端：基站侧小区
基站侧小区接收到终端UE1上报的P-ABILITY MAC CE，并解出里面的G-RNTI字段的值为31，P字段为0，则认为UE1处于G-RNTI为31的集群组呼被叫业务，且该终端的PDCCH盲检能力为高。
基站侧小区接收到终端UE2上报的P-ABILITY MAC CE，并解出里面的G-RNTI字段的值为31，P字段为0，则认为UE2处于G-RNTI为 31的集群组呼被叫业务，且该终端的PDCCH盲检能力为高。
基站侧小区接收到终端UE3上报的P-ABILITY MAC CE，并解出里面的G-RNTI字段的值为31，P字段为0，则认为UE3处于G-RNTI为31的集群组呼被叫业务，且该终端的PDCCH盲检能力为高。
进一步地，基站侧小区收集集群组呼中各RRC_Connected状态的终端的盲检能力，并确定或者更新该集群组呼的盲检能力。具体为：基站侧小区收集到G-RNTI为31的集群组呼被叫业务中的RRC_Connected状态的终端为UE1、UE2和UE3，其盲检能力均为高，则判断集群组呼的盲检能力为高。
进一步地，基站侧小区依据该集群组呼的盲检能力对该集群组呼业务进行调度。具体为：基站侧小区对判断当集群组呼的盲检能力为高时，则对该集群组呼业务所对应的G-RNTI放在专用空间进行调度。
