演进多媒体广播多播业务基站、 用户设备和方法
技术领域
本发明涉及移动通信领域, 尤其是第三代移动通信领域的长期演进( LTB )技术, 更具体地, 涉及一种支持演进多媒体广播多播业务(Evolved- MBMS )专用载频的基站 ( eNB )、 用户设备(UB )和方法。 背景技术
多媒体广播多播业务 MBMS ( Mul t imedia Broadcas t Mul t icast Services ) 是
3GPP R6的新功能, 同时也是基于正交频分复用 ( OFDM )的 3GPP长期演进系统( LTB ) 中的重要功能。 在 LTB中称为 B - MBMS (演进的 MBMS ) , 在本发明中, 统称为 MBMS。
在将来的移动网络规划中, 由午 MBMS业务占用很多无线资源 , 为了节约无线资 源, MBMS采用专用载频是一种通常的方法。这意味着在 MBMS专用载频上,只支持 MBMS 业务, 不支持任何非 MBMS业务。
3GPP R6还没有专用载频方案, MBMS业务启动前, UTRAN( Universal Terres tr ial Radio Acces s Network , 通用陆地无线接入网络) 使用 FLC ( Frequency Layer Convergence, 频率层会聚)技术使对该 MBMS 业务感兴趣的 UE (用户设备) 重选到 MBMS专用载频。在 MBMS业务结束后, UTRAN又使用 FLD( Frequency Layer Dispers ion, 频率层发散)技术, 由网络发出一条频率层离散的指示信息, UE根据指示信息进行发 散到其它载频上 (即正常载频, 支持任何非 MBMS业务)。 如图 1B所示, ( 1 ) UB原 来驻留在正常载频 1 , 当 MBMS业务启动后, RNC下发 FLC指示给 UE。 ( 2 ) UE选择到 MBMS业务所在的载频 2接收 MBMS业务。 ( 3 ) MBMS业务结束后, RNC在载频 2上下发 FLD指示给 UB。 ( 4 ) UE重选到载频 1。
在现有协议中的技术虽然可以将 MBMS 业务集中到某个载频上, 如果要发起非
MBMS业务, 一种方法是重选到非 MBMS载频上完成, 即使是一些最简单的操作, 如位 置区更新, 接收或者发送短消息, 这样很容易丢失 MBMS数据; 另一种方法是在 MBMS 所在载频上进行, 缺点是 MBMS所在载频容量有限, 只能提供有限的非 MBMS业务, 而 且该载频覆盖范围无法很大, 即使提高下行发射功率, 因为 UE的上行发射功率有限, 不支持大范围小区。 在该载频上 MBMS业务和非 MBMS业务还是混合发射。 而且现有协议中的对载频的分配都是上下行成对分配(如图 1A所示), 而 MBMS 业务只需要下行数据发送, 换句话说, 该上行载频是浪费的。 ' '
因此, 该技术存在以下缺点:
( 1 )由于在所谓的专用载频上 MBMS业务和非 MBMS业务混合的方式,上行受限, 该载频的覆盖范围无法很大, 即使提高下行发射功率, 仍无法实现;
( 2 )上述不同载频之间的切换和重选过程比较复杂;
( 3 )上述技术必须使用成对载频。
因此, 需要一种支持演进多媒体广播多播业务专用载频的系统和方法, 能够使 系统结构得到简化, 很好地满足了 MBMS性能需求, 而且 MBMS使用专用载频, 可以使 承载 MBMS 业务的载频能够使用更高的发射功率, 更大的覆盖范围, 使得建网成本得 到降低。 发明内容

在本发明的专用载频系统中, MBMS业务和非 MBMS业务承载在不同的载频上, 为 了下面说明方便, 将承载 MBMS业务的载频称为 MBMS专用载频, 承载非 MBMS业务的 载频称为非 MBMS载频。 - UE驻留在非 MBMS载频, 在驻留载频上, UE可以发起呼叫、 小区更新 /位置区更 新、 收到寻呼等过程。 MBMS专用载频信息、 MBMS业务公告、 MBMS业务通知在非 MBMS 载频上下发。 而 MBMS信道配置、 MBM^调度、 MBMS数据等信息在 MBMS专用栽频上下 发。 ' .

图 5C是示出了根据本发明的 UE的具体操作的流程图。
如图 5C所示, 最初, 在步骤 S500, UE驻留在非 MBMS载频上, 通过非 MBMS载 频上的广播信道接收 MBMS 专用载频相关信息(包括频率、 带宽等信息) 。 接下来, 在步骤 S502 , ϋΕ #■据在非 MBMS载频上接收到的 MBMS业务公告, 加入感兴趣的 MBMS 业务组。 此外, 如果 UE接收到 MBMS计数请求, 则返回 MBMS计数响应, 表明 UB是否 对该 MBMS业务感兴趣; 当然, eNB也可以不下发 MBMS计数请求, 不对感兴趣的 UB进 行计数。 当 MBMS业务准备启动时, 相应的 MBMS通知在非 MBMS载频和 MBMS专用载频 下发。 当 UB接收到感兴趣的 MBMS业务的 MBMS通知时(步驟 S504 ) , UE准备接收该 MBMS业务, 在步骤 S506 , 选择 MBMS专用载频, 并在步骤 S508 , 在 MBMS专用载频上 接收系统消息, 其中包括 MBMS RB (无线承载) 配置信息以及 MBMS业务调度信息, 从 而根据 MBMS RB配置信息以及 MBMS业务调度信息, 产生准备接收的 MBMS业务的调度 模板。 在步驟 S510, UE根据所产生的 MBMS业务调度模板, 在发送 MBMS数据的定时, 接收 MBMS数据。 在 MBMS数据发送的空隙, 在步骤 S512 , 确定 MBMS数据发送是否结 束。 如果 MBMS数据发送尚未结束(步骤 S512中的 "否" ) , 则在步骤 S514 , UE在 接收 MBMS数据发送的空隙,返回驻留的非 MBMS载频, 处理非 MBMS业务相关操作(如 接收寻呼, 位置区更新等) , 然后在下一个调度数据发送前返回 MBMS 专用载频继续 接收 MBMS数据(步骤 S510 )。另一方面,在 MBMS任务停止后(步骤 S512中的 "是" ;), 在步骤 S516 , UE返回驻留的非 MBMS载频, 不再在 MBMS专用载频上接收数据。
对于双接收机 UB,其中的一个接收机 ( 1320 )接收 MBMS业务( MBMS专用载频), 不需要在空隙内返回非 MBMS载频; 而另一个接收机 ( 1310 )驻留在非 MBMS载频。 由 载频选择单元 1400确定将哪个接收机接收到的数据传递给控制器 1100进行处理。
图 5D是用于解释 UE在 MBMS专用载频和非 MBMS专用载频之间的切换过程的示 意图。
如图 5D所示, UB在 MBMS专用载频和非 MBMS载频之间进行切换。 结合图 5C可 知, 步驟 S500和 S502在非 MBMS载频上完成。 步骤 S504可以在 MBMS专用载频和非 MBMS载频之一上完成。 在步骤 S506, UE切换到 MBMS专用载频, 并在完成步骤 S508 种的接收步骤之后, 返回非 MBMS载频。 但是, UE也可以不返回非 MBMS载频, 一直保 持在 MBMS专用载频上, 也可以根据所产生的 MBMS业务调度模板中的信息来确定是返 回非 MBMS载频, 还是保持在 MBMS专用载频上。 步骤 S510在 MBMS专用栽频上完成。 步骤 S514在非 MBMS载频上完成。 重复步骤 S510 - S514 , 直至 MBMS数据发送结束。 最后, 在步骤 S516 , 返回非 MBMS载频。
下面, 对 UE在 MBMS专用载频上接收 MBMS数据期间建立非 MBMS业务的操作进 行详细描述。
图 6示出了 MBMS业务调度的例子。
( 1 ) UE主叫过程
如果在 MBMS专用载频上接收 MBMS数据期间 (步骤 S510期间)要建立非 MBMS 业务, UE首先进行业务优先级判断, 如果非 MBMS业务具有高优先级, 则 UB返回驻留 的非 MBMS载频, 发起非 MBMS业务; 非 MBMS业务结束后, UE继续 MBMS业务的接收过 程。 如果 MBMS业务的优先级较高, 则继续接收 MBMS数据, 等到 MBMS数据发送的空 隙, 再对非 MBMS业务进行处理 (步骤 S.514 ) 。
( 2 ) UE被叫过程
当 UE被叫一个非 MBMS业务时, eNB将通过寻呼通知 UE, 根据寻呼消息发送方 式的不同, 有两种方法: ①寻呼在 MBMS专用载频和非 MBMS载频上发送, ②寻呼只在 非 MBMS载频上发送。
①寻呼在 MBMS专用载频和非 MBMS载频上发送
正在 MBMS专用载频上接收 MBMS业务的 UE接收到寻呼后, UE执行业务优先级判 断, 如果非 MBMS业务优先级高, UE返回驻留的非 MBMS载频, 在非 MBMS载频上响应 寻呼。 如果 MBMS业务的优先级较高, 则继续接收 MBMS数据, 等到 MBMS数据发送的 空隙, 再对非 MBMS业务进行处理(步骤 S514 ) 。
该方法的优点是 UE不需要频繁返回驻留的非 MBMS载频, 这样可以省电。
②寻呼只在非 MBMS载频上发送。
根据上述步驟 S514> UE在调度空隙返回非 MBMS载频时接收寻呼。
优点是寻呼范围减小, 降低了对寻呼信道容量的需求, 而且简化的 MBMS专用载 频的结构。
图 7示出了根据本发明的演进基站 eNB的结构方框图。
如图 7所示, 根据本发明的演进基站 eNB 2000包括 eNB控制器 2100、 发送单元 2200、 接收单元 2300、 计数结果生成单元 2400和 RB建立单元 2500。
发送单元 2200执行各种信息和数据的发送, 包括在非 N^BMS载频上发送 MBMS计 数请求、 在非 MBMS载频上发送 MBMS数据、 在非 MBMS载频上发送 MBMS通知、 以及在 MBMS专用载频上发送 MBMS通知、 RB配置信息、 MBMS业务调度信息等。
接收单元 2300执行各种信息和数据的接收, 并将各种信息和数据传递给 eNB控 制器 2100。 而且, 接收单元 2300接收来自 UE的 MBMS计数响应, 并将 MBMS计数响应 传递给计数结果生成单元 2400。
计数结果生成单元 2400根据从接收单元 2300传递过来的 MBMS计数响应, 根据 包含在 MBMS计数响应中的 UE是否对该 MBMS业务感兴趣的信息,生成 MBMS计数结果, 并将 M S计数结果传递给 eNB控制器 2100。
RB建立单元 2500负责根据 eNB控制器 2100的指令, 建立符合要求的无线承载 RB。
eNB控制器 2100控制上述各个单元的操作,根据计数结果生成单元 2400所生成 的 MBMS计数结果, 确定是否要建立 RB, 以及应当建立何种 RB。 当需要建立 RB时, eNB控制器 2100控制 RB建立单元 2500建立相应的 RB ,并控制发送单元 2200在非 MBMS 载频上发送 MBMS通知,并同时在 MBMS专用载频上发送 MBMS通知、 RB配置信息、 MBMS 业务调度信息; 之后, 根据 MBMS业务调度信息, 控制发送单元 2200在 MBMS专用载 频上发送 MBMS数据。 . 在本发明中, 如图 4B所示, 生成 MBMS计数结果的基站(eNBl ) 可以不同于建 立 RB的基站( eNB2 )。因此,在以上操作中,第一基站的发送单元可以将所生成的 MBMS 计数结果通过 X2接口直接传递给负责建立 RB的第二基站。 所述第二基站的 eNB控制 器根据接收单元通过 X2接口接收到的 MBMS计数结果来执行后续操作。 或者, 第一基 站的发送单元可以将所生成的 MBMS计算结果通过 S1接口传递给接入网关, 并由接入 网关再通过 S 1接口传递给第二基站。 所述第二基站的 eNB控制器根据接收单元通过 S1接口接收到的 MBMS计数结果来执行后续操作。 在这种情况下, 第一基站可以只工 作在非 MBMS载频上, 而第二基站可以^工作在 MBMS专用载频上。
8是示出了根据本发明的演进基站 eNB的计数过程和 RB建立操作的流程图。 在步驟 S800, eNB在非 MBMS载频上发送 MBMS计数请求。 UE在接收到 MBMS计数 请求.之后 , 发送 MBMS计数响应, 在 MBMS计数响应中, 表明 UE是否对该 MBMS业务感 兴趣。 在步驟 S802 , eNB接收 MBMS计数响应, 并在步驟 S804 , 根据 MBMS计数响应, 生成 MBMS计数结果。 然后, 在步骤 S806, eNB根据 MBMS计数结果, 确定是否要建立 RB, 以及应当建立何种 RB。 如果确定要建立 RB (步骤 S806中的 "是"), 则 eNB在步 驟 S810建立相应的 RB, 并执行步骤 S812 , 在非 MBMS载频上发送 MBMS通知, 同时, 在 MBMS专用载频上发送 MBMS通知、 RB配置信息、 MBMS业务调度信息。 之后, 根据 MBMS业务调度信息, 在步骤 S814, eNB在 MBMS专用载频上发送 MBMS数据。
如果确定不建立 RB (步骤 S806中的 "否 "), 则在步骤 S808 , 处理结束。
本发明中, 非 MBMS 载频也可以是 WCDMA/GSM等其它无线接入系统, 如图 9, WCDMA/GSM的无线接入网 ( UTRAN/GBRAN )通过 SGSN (服务 GPRS支持节点 )接到 aGW。 在这种网络结构下, 本发明的只要在前述方案中稍做改变, 不需要涉及 2种载频之间 交互的流程, 如非 MBMS载频的计数过程等。
利用本发明, MBMS专用载频可以使用资源丰富的非成对载频; 覆盖范围大; 系 统简单, 可以独立组成多媒体广播网; 而且对非 MBMS业务的影响小。 最后所应说明的是: 以上实施例仅仅用以说明而非限制本发明的技术方案, 尽 管参照上述实施例对本发明进行了详细说明, 本领域的普通技术人员应当理解, 可以 对本发明进行修改或者等同替换, 而不脱离本发明的精神和范围的任何修改或局部替 换, 其均应涵盖在本发明的权利要求范 '围当中。
