综上所述, 本发明实施例在 LTE系统标准协议基础上, 通过上下行方向 新增集群业务专用逻辑信道的方式实现集群功能, 在同一个系统同时支持 LTE业务和集群业务的并发。 可以在 LTE系统基础上实现集群通信的需求, 实现了集群业务和 LTE业务在同一个系统中的并存。 附图概述
图 1为本发明实施例的实现集群业务的方法的流程图;
图 2为本发明实施例的演进的节点 B的架构图;
图 3为本发明实施例的终端的架构图;
图 4为本发明实施例的另一种终端的架构图。 本发明的较佳实施方式
本发明实施例基于 LTE实现集群业务, 目前也有一些基于 LTE实现集 群业务的方法,但这些方法都没有充分考虑到 LTE业务和集群业务并存时的 设计, 并且集群业务的逻辑信道釆用不同标识来区分, 占用了 LTE协议中过 多的逻辑信道资源, 在后续 LTE协议扩展时集群业务会受到影响。 本发明实 施例充分考虑到上述因素, 提出釆用 MAC头中的保留位来区分集群业务的 逻辑信道, 减少对 LTE资源的占用。
LTE现有协议中的专用信道都是点对点的通讯方式, 无法满足集群业务 的需求。 为在 LTE系统中实现集群业务, 需要在 LTE系统中增加集群专用 信道, 本实施方式中增加如下信道:
在下行方向增加集群寻呼控制信道 ( TPCCH, Tmnking Paging Control Channel ) 、 集群业务信道 ( TGTCH, Tmnking Group Traffic Channel )和集 群控制信道(TGCCH, Tmnking Group Control Channel ) , 承载集群终端的 下行控制消息和下行业务数据;
在上行方向增加集群公共控制信道( TCCCH, Tmnking Common Control Channel ) , 承载集群终端的上行消息。
本实施方式中的集群相关信令和数据承载在不同逻辑信道上从而实现 LTE系统上的集群业务, 同时保证了原来 LTE业务也能正常进行。本发明实 施例充分考虑到 LTE业务和集群业务并存的场景下业务的实现,具有广阔的 市场应用前景。
下面分别对上述在 LTE中新增的集群专用信道进行说明:
下行方向:
TGTCH 集群业务信道, 为点到多点模式, 用于承载集群业务的下行业 务数据。
TGCCH 集群控制信道, 为点到多点模式, 承载集群业务的下行控制消 息, 包括组呼建立和释放、 话权通知、 邻区资源信息、 PDS (调度台)和终 端间下行 NAS (非介入层 )等控制消息。
TGTCH和 TGCCH均映射在下行共享信道(DL-SCH )上, 由群组对应 的群组无线网络临时鉴定 (T-RNTI , 在一个 eNB 下每个群组有唯一的 T-RNTI )加扰, 实现下行数据广播, 群组内多个终端同时解调的功能。
为与 LTE专用信道相区别, 对新增的 TGTCH和 TGCCH承载的业务在 对消息组包时将封装消息的数据包的 MAC头的两个保留位设置为 11 (或者 01或 10 ) , 而 LTE专用信道上承载的业务在组包时 MAC头的保留位置为 00, 而逻辑信道标识(LCID )仍然使用 LTE协议规定范围(00001 01010 ) 。
TPCCH集群寻呼控制信道, 为点到多点模式, 用于承载集群寻呼消息, 携带群组的 T-RNTI。 TPCCH映射在集群寻呼信道 ( TPCH )上, 由 TP-RNTI 来进行力口扰。
上行方向:
TCCCH 集群公共控制信道, 为点到点模式, 用于承载集群终端的上行 消息, 包括: 话权申请, 终端给 eNB上报 CQI信息, 终端给 PDS发送集群 信令和终端状态信息等, 映射在上行共享信道(UL-SCH )上, 上报给 eNB。
TCCCH上消息所封装的数据的 MAC头中的保留位设置为 11(或 01或 10 ), 和 LTE数据区分。
对于集群业务中的说用户 (正在讲话的用户) , 在上下行方向分别复用 LTE系统原有的专用控制信道(DCCH )承载专用信令, 复用原有专用业务 信道(DTCH )承载专用数据, 通过 MAC头中的保留位来实现 LTE业务和 集群业务的区分。 DTCH用于基于 LTE的集群业务时, MAC PDU Header的 保留位设置为 11 (或者 10或者 01 ) , 否则设置为 00。 LCID范围仍然使用 LTE协议规定的范围 ( 00001-01010 ) 。
当说用户同时进行 LTE业务和集群业务时, eNB可以根据 MAC头中的 保留位判断当前是 LTE业务数据还是集群业务数据。
本实施方式的实现集群业务的方法, 包括以下步骤:
步骤一:集群终端向 eNB发起呼叫请求消息,如果为集群呼叫请求消息, 则上行消息承载在 TCCCH上, 消息封装的数据包的 MAC头中的保留位设 置为 11 (或 01,10 ) 。
如果为 LTE呼叫, 则上行消息承载在 CCCH上, 消息封装的数据包的
MAC头中的保留位设置为 00。
eNB根据解调的 MAC头中的保留位来判断呼叫请求消息是否为集群呼 叫请求消息,如果为集群呼叫请求消息,向 PDS发送建立组呼的请求; 否则, 为 LTE接入, 向 MME发送连接建立请求。 下面以集群呼叫为例说明。
步骤二: PDS授权给起呼终端, 起呼终端和 eNB建立上下行 DTCH信 道承载起呼终端的上下行业务数据,建立专用的上下行 DCCH信道承载起呼 终端和 eNB之间的控制消息。
步骤三: eNB通过 TPCCH寻呼处于听状态的集群终端,听终端在 TCCCH 信道上返回寻呼响应消息, eNB 在有寻呼响应消息的小区建立 TGCCH和 TGTCH, 并将建立的 TGTCH的信道资源信息通过 TGCCH向听终端广播。
步骤四: 听终端利用 TPCCH中携带的 T-RNTI, 解调出 TGCCH, 获取 携带的 TGTCH的信道资源信息, 监听 TGTCH信道。
步骤五: 起呼终端的集群数据(语音数据)通过专用的 DTCH上传到
PDS, PDS在 TGTCH信道的小区通过 TGTCH转发起呼终端的语音数据 (或 者其它业务数据, 通常集群数据) , 集群组内的听用户解析出 TGTCH上的 语音(或者其它业务数据) , 从而实现集群通信需求。
下面结合附图和具体实施方式对本发明的具体实施作进一步详细说明。 本实施方式为了在 LTE系统实现集群业务,增加了几种集群业务专用的 上下行逻辑信道。
下行方向: 引入 TGTCH集群业务信道, 为点到多点模式, 用于承载集 群业务数据。 引入 TGCCH集群控制信道, 为点到多点模式, 承载集群终端 的控制消息, 包括组呼建立和释放、 话权通知、 邻区资源信息、 PDS和终端 间下行 NAS等控制信息。引入 TPCCH集群寻呼控制信道,为点到多点模式, 用于承载集群寻呼消息, 携带群组的 T-RNTI。
上行方向, 引入 TCCCH集群公共控制信道, 为点到点模式, 用于承载 话权申请, 终端给 eNB上艮 CQI信息, 终端给 PDS发送集群信令和终端状 态信息等。
在单呼场景和组呼场景中, 对说用户, 在上下行方向分别复用 LTE系统 原有的 DCCH信道承载专用信令,复用原有 DTCH信道承载专用数据,通过 MAC PDU Header中的保留位来实现 LTE业务和集群业务的区分, DTCH 在用于集群业务时, MAC PDU Header的保留位设置为 11(或者 10或者 01 ), 否则设置为 00。 当说用户同时进行 LTE业务和集群业务时, eNB可以根据 MAC头中的保留位断当前是 LTE业务数据还是集群业务数据。
