Description

一种信息发送的方法、 装置和系统 技术领域
本发明涉及通信技术领域, 特别涉及一种信息发送的技术。
背景技术
用户设备 ( User Equipment, UE )的电量消耗现在已经成为制约移动通信 技术发展的重要因素, 为了节省 UE的电量, 对于非实时业务, UE开始采用 非连续接收 ( Discontinuous Reception, DRX )技术。 该技术主要是针对每个 UE的业务特性, 配置与其业务相适应的 DRX周期。 其中 DRX周期包括了两 种状态 , 分别为 DRX接收状态和 DR 休眠态。
只有在处于 DR 接收状态时, UE才会打开收发信机, 监控基站发送信 号, 在处于 DR 休眠态时, UE可以关闭收发信机, 不监控基站发送信号, 从而降低了功率消耗, 延长了电池的使用时间。
家庭基站(也称为私有基站或者室内接入点等)是一种扩展移动通信室内 覆盖的解决方案, 可以连接到基于网际协议(Internet Protocol, IP ) 的传送网 络, 能够利用核心网的分组交换来传输话音等实时业务, 资费便宜、服务质量 好、 支持高速率数据业务的传输。
由于家庭基站的用户较少, 且大部分业务可以采用 DRX模式进行接收, 所以为了降低 UE的电池消耗, UE可以采用 DR 模式接收。 因此, 在家庭基 站( Home E-UTRAN Node B , HeNB )所服务的用户均处于 DR 休眠态或者 空闲 (Idle ) 态时, 没有一个 UE的下行数据需要发送, 也没有一个 UE会接 收 HeNB下发的开销消息(例如为导频、 同步信号、广播消息等)。如果 HeNB 此时仍然按照自己的周期不断发送上述消息,则会对其他扇区造成不必要的干 扰, 同时也会造成功率开销的浪费。
为此, HeNB可以采用非连续发送(Discontinuous Transmission, DTX ) 技术,仅在有服务用户的子帧才发送上述开销消息,而在所有 UE都处于 DRX 休眠态或者空闲态时, HeNB不发送任何形式的消息, 也处于休眠态。 此时, HeNB可以关闭该载波的收发信机, 从而降低了功率消耗、 减小了对其他扇区 的干扰、 提高了系统容量和频谱效率。 同样, 当 HeNB采用多载波配置方案时, 主载波主要用于 UE的初始接入 和维持少量的数据业务, 而辅载波主要用于数据业务的传输, 对于 UE而言大 部分数据业务都可以采用 DRX模式接收, 因此, 相应的 HeNB的辅载波就可 以采用 DTX模式发送, 以减小 HeNB的开销和干扰。
但是, 当载波处于 DTX模式时, 会导致 UE无法测量或者扫描到该载波 的导频, 从而影响 UE对于该载波的使用。

进一步的, 确认为用户终端使用处于 DTX模式的辅载波, 具体可以为: 根据当前业务量和 /或所述用户设备的业务质量, 确认为所述用户设备使用处 于 DTX模式的辅载波。
进一步的, 在步骤 201或者步骤 202之后, 还可以包括: 重新配置该辅载 波的 DTX模式的周期。
其中,导频发射的方式包括下述之一或其任意组合: 按照正常工作模式的 方式发射导频; 按照发射开始时间和发射持续时间发射导频; 按照所述辅载波 的 DTX模式的周期发射导频。
通过本发明的第二实施例, 可以在 UE需要使用辅载波时, 向 UE发送相 应的辅载波信息, 并改变该辅载波的 DTX模式, 使得 UE可以测量该辅载波 的导频, 从而顺利使用该辅载波。
下面结合附图 3 , 详细描述本发明的第三实施例。 本发明的第三实施例也 提供了一种信息发送的方法, 该方法包括:
步骤 301, ΜΜΕ获取 HeNB的位置信息。
本实施例主要是针对 HeNB为单载波配置, 且该载波处于 DTX模式, 但 是步骤 301并不要求以该载波处于 DTX模式为前提条件。 MME获取 HeNB 的位置信息可以有多种方式,例如在 HeNB每次开机与网络侧建立 S1连接时, MME会获知该 HeNB的位置信息。 例如 MME还可以在 S1连接重建过程或 HeNB配置更新过程中, 获知 HeNB的位置信息。
MME获知 HeNB的位置信息只需要在步骤 303之前执行, 没有特定的执 行时间或者特定的执行流程。
其中, 位置信息可以是多种信息, 例如为跟踪域标识 (Tracking Area Identity, TAI )。
进一步的, HeNB的位置信息还可以是全球定位系统(Global Positioning System, GPS )信息。 相应的该 GPS信息可以是 HeNB获得并发送给 MME 的, 可以在现有的流程和消息中携带相应的信元( Information Element , IE ) 告知 MME本 HeNB的 GPS信息。
步骤 302, MME获取 UE的位置信息。
在 UE初始接入时, MME就可以获知 UE的位置信息, 此后在 UE位置 发生变化时, MME也可以获知 UE最新的位置信息。例如在发生切换时和 UE 进行位置域更新时, MME均可获知 UE的位置信息。其中位置信息例如为 TAI。
此外,位置信息也可以是 GPS信息。该 GPS信息可以是在 UE中加入 GSP 模块从而获知 UE本身的 GPS信息, 并在现有流程的消息中或者新的消息中 传递给 MME。 进一步的, 该 GPS信息还可以是基站获知的该 UE的 GPS信 息, 并通过现有流程的消息或者新的消息发送给 MME。
需要说明的是, 步骤 302只需要在步骤 303之前完成, 并没有特定的完成 时间或者流程。 由此可知, 步骤 301与步骤 302之间也没有特定的执行顺序, 可以同时执行, 也可以先执行步骤 301后执行步骤 302, 反之亦然。
本领域普通技术人员可以理解,步骤 301与步骤 302还可以通过其他流程 完成, 只要使得 MME能够获知 UE和 HeNB的位置信息即可。
步骤 303 , MME判断 UE和 HeNB的位置关系 , 在 UE处于该 HeNB附 近时执行步骤 304。
通过步骤 301和步骤 302, MME可以获知 UE和 HeNB的位置信息, 从 而 MME可以判断 UE是否接近了 HeNB, 即 UE和 HeNB的位置关系。
例如, 当 UE的 TAI与 HeNB的 TAI相同的时候, MME可以判断 UE已 经处于该 HeNB的附近了。
例如, 网络侧可以记录 HeNB附近的 eNB和其他 HeNB的 TAI, 当 UE 的 TAI与上述 eNB或者其他 HeNB的 TAI相同的时候 , MME可以判断 UE已 经处于该 HeNB的附近了。
例如 , MME还可以通过 UE和 HeNB的 GPS信息更精确的定位 UE是否 处于 HeNB的附近。 在这种情况下, 例如可以设置一个阔值, 在 UE和 HeNB 之间的距离小于或者等于阔值时, MME判断 UE已经处于该 HeNB的附近了。
通过上述方法判断 UE处于 HeNB附近时, 执行步骤 304, 如果判断 UE 未处于 HeNB附近, 则不执行后续步骤。
进一步的步骤 303中还可以包括对 UE进行鉴权, 判断 UE是否具有使用 某个 HeNB的权限。
例如, 可以在通过上述方法判断 UE处于 HeNB附近时, MME对 UE进 行鉴权, 检测该 UE是否有接入该 HeNB的权限。 在 UE有接入该 HeNB的权 限时执行步骤 304,在 UE没有接入该 HeNB的权限时不进行后续操作。其中, MME对 UE的鉴权过程可以利用现有的鉴权过程, 例如通过向核心网设备发 送询问消息。
步骤 303中 , MME对 UE和 HeNB的位置关系的判断和对 UE进行鉴权 还可以进一步的结合起来。
例如, MME在 UE位置发生变化时, 先检测 UE有权限接入哪些 HeNB, 该检测过程也可以利用现有的流程。 此后 MME再判断 UE是否处于上述有权 P艮接入的 HeNB的附近。如果位于上述有权限接入的 HeNB附近,则执行步骤 304, 否则, 不进行后续操作。
进一步的 , MME可以记录 UE有权限接入的 HeNB ,在检测 UE有权接入 哪些 HeNB 时, 不用再访问核心网设备, 直接在 UE位置发生变化时, 判断 UE是否处于记录的 UE有权接入的 HeNB的附近。 如果位于上述有权接入的 HeNB附近, 则执行步骤 304, 否则不进行后续操作。
步骤 304, MME向 HeNB发送靠近指示。
MME向 HeNB发送靠近指示, 告知 HeNB有 UE位于该 HeNB的附近, 用于指示 HeNB发送开销消息。 其中开销消息例如为导频、 同步信号、 广播消 息等。 该指示可以在现有流程的消息中发送, 也可以在新消息中发送。
进一步的, MME在给 HeNB发送靠近指示时, 还可以将处于该 HeNB附 近的 UE的标识( UE ID )发送给 HeNB。 UE ID可以随上述靠近指示一 送, 也可以在其他消息中发送。
步骤 305 , HeNB发送开销消息。
HeNB在接收到 MME发送的靠近指示后, 改变其工作模式, 开始发送开 销消息。 其中, 开销消息用于 UE使用该载波。 开销消息例如包括导频、 同步 信号、 广播消息等。 其中 HeNB改变工作模式例如可以为, HeNB的载波由原来的 DTX模式 变为正常工作模式, 即周期性发送同步信号、 广播消息等, 在每个子帧发射导 频。
HeNB改变工作模式例如还可以为, HeNB的载波在 DTX模式和正常工 作模式之间周期性轮换。 由于 HeNB的载波在这种改变工作模式的方式下,还 是部分时间处于 DTX模式的,所以对于 UE只接近 HeNB而没有接入的情况, 这种改变工作模式的方式可以更为有效的节省开销、 降低干扰。
HeNB改变工作模式例如还可以为, HeNB的载波在 DTX模式和正常工 作模式之间非周期的轮换。 例如可以 DTX模式工作时间越来越长, 正常工作 模式的工作时间越来越短或者保持不变; 或者 DTX模式工作时间越来越短, 正常工作模式的工作时间越来越长或者保持不变; 或者 DTX模式工作时间保 持不变, 而正常工作模式的工作时间越来越长或者越来越短。 由于 UE也具有 测量周期, 所以 HeNB的载波在 DTX模式和正常工作模式之间非周期性的轮 换可以避免 UE的测量周期与轮换周期重合, 从而避免导致 UE无法接收到正 常工作模式下发送的开销消息, 使得 UE可以更顺利的使用该载波。
通过 HeNB工作模式的改变, HeNB会发送开销消息, 从而使得 UE可以 根据上述开销消息使用该 HeNB的载波。
本领域普通技术人员可以获知, 在步骤 305中, HeNB根据接收到靠近指 示改变工作模式,通常的实现方式为 MME只发送一个靠近指示,以告知 HeNB 有 UE靠近,而 HeNB在接收到该靠近指示后,按照自己的设定改变工作模式, 即 HeNB具体改变为哪种工作模式并不由 MME决定。
但是, 也可以由 MME决定 HeNB改变为哪种工作模式, 并通过靠近指示 告知 HeNB改变为哪种工作模式, 即 HeNB具体改变为哪种工作模式由 MME 决定。
步骤 306, HeNB在 UE接入后, 再次进入 DTX模式。
该步骤为可选步骤, 在步骤 304中, MME在给 HeNB发送靠近指示时, 还可以发送 UE ID。 HeNB可以通过该 UE ID判断该 UE是否已经接入了本 HeNB, 如果判断结果为已经接入, 则 HeNB可以再次进入 DTX模式, 而如 果是未接入, 为了该 UE能够获取上述开销消息, HeNB仍需要保持正常工作 模式, 或者保持正常工作模式与 DTX模式的轮换。
通过本发明的第三实施例, MME获取了 UE和 HeNB的位置信息后, 通 过判断 HeNB和 UE的位置关系,在 UE靠近 HeNB时指示 HeNB改变工作模 式, 开始发送开销消息, 从而保证了 UE顺利使用该 HeNB的载波。
下面结合附图 4, 详细描述本发明的第四实施例。 本发明的第四实施例也 提供了一种信息发送的方法, 该方法包括:
步骤 401, UE测量服务小区的邻小区信息, 在 UE接近 HeNB时, 执行 步骤 402。
在 UE中保存有该 UE能够接入的 HeNB周围的 eNB和 /或 HeNB的小区 ID。 例如, 在 UE加入 HeNB接入权限时, 网络侧可以为 UE配置该 UE可以 接入的 HeNB周围的 eNB和 /或 HeNB的小区 ID。
UE在进行邻小区信息的测量时, 会获得邻小区的小区 ID。 其中对邻小区 信息进行测量既可以是通过现有的测量流程(例如切换判决流程), 也可以是 配置新的测量事件。
在 UE获知邻小区的小区 ID后, 如果邻小区的小区 ID在 UE保存的上述 小区 ID中, 则认为该 UE在 HeNB的附近, 执行步骤 402, 否则不执行后续 步骤。
进一步的 , UE也可以保存该 UE能够接入的 HeNB周围的 eNB和 /或 HeNB 的 ID,并在测量邻小区信息时,获得 eNB和 /或 HeNB的 ID,如果获得的 eNB 和 /或 HeNB的 ID与 UE保存的 eNB和 /或 HeNB的 ID相同, 则判断该 UE在 HeNB的附近, 执行步骤 402, 否则不执行后续步骤。
步骤 402, UE向服务小区发送接近指示。
通过步骤 401进入步骤 402后, 就说明 UE已经处于 HeNB的附近了。 因 此, UE向服务小区发送接近指示, 用以指示 UE已经接近 HeNB了。 该接近 指示的发送可以利用现有流程, 也可以在新的消息中发送。
UE向服务小区发送接近指示时,还可以发送 HeNB的 ID, 其中 HeNB的 ID可以与上述接近指示一起发送给服务小区, 也可以在新的消息或者流程中 发送给服务小区。
步骤 403 , 服务小区转发该接近指示。 服务小区在接收到 UE发送的接近指示后 , 将该接近指示转发给 MME。 在向 MME转发该接近指示时, 可以将 HeNB的 ID与该接近指示一起转发, 也可以单独转发 HeNB的 ID。
进一步的, 服务小区向 MME转发该接近指示时, 还可以将该 UE的 ID 发送给 MME。
步骤 404, MME向 HeNB发送靠近指示。
MME在接收到服务小区转发的接近指示后, 向 HeNB发送靠近指示, 告 知 HeNB已经有 UE位于该 HeNB的附近,指示 HeNB开始发送开销消息。本 领域普通技术人员可以理解, 可以让 UE发送的接近指示与 MME发送的靠近 指示相同, 在这种情况下, MME只需要向 HeNB转发该接近指示即可; 也可 以让 UE发送的接近指示不同于 MME发送的靠近指示, 该接近指示仅用于让 MME获知 UE已经靠近了 HeNB, 而 MME的靠近指示用于让 HeNB获知 UE 已经靠近了 HeNB。
进一步的, 步骤 404 中还可以包括检测 UE是否有权限接入 HeNB, 即 MME判断 UE是否有权限接入其靠近的 HeNB , 如果有则向该 HeNB发送靠 近指示, 如果没有, 则不进行发送靠近指示的操作以及其他后续操作。
进一步的 , MME可以将 UE的 ID发送给 HeNB,该 UE ID可以是服务小 区转发的, 也可以是 MME直接获取的。
步骤 405 , HeNB发送开销消息。
步骤 405的具体实现可以参见本发明的第三实施例的步骤 305。
步骤 406, HeNB在 UE接入后, 再次进入 DTX模式。
步骤 406的具体实现可以参见本发明的第三实施例的步骤 306。
通过本发明的第四实施例, 可以通过 UE对邻小区信息的测量判断 UE是 否靠近了某个 HeNB, 并且在靠近某个 HeNB时发送接近指示, MME通过服 务小区转发该接近指示获知 UE靠近了 HeNB, 从而指示 HeNB开始发送开销 消息,使得 UE可以顺利使用该 HeNB的载波。并且,对 UE是否有接入 HeNB 权限的检测进一步保证了在 UE不能接入 HeNB时, HeNB不会改变 DTX模 式, 更好的节省了 HeNB的开销, 降低了干扰。
下面结合附图 5, 详细描述本发明的第五实施例。 本发明的第五实施例也 提供了一种信息发送的方法, 该方法包括:
步骤 501, HeNB判断是否为 UE使用处于 DTX模式的辅载波 a, 如果是 则执行步骤 502。
通常情况下, HeNB的主载波主要用于 UE的初始接入和少量业务的维持, 而辅载波主要用于数据业务的传输。
当 HeNB的主载波或者辅载波的负荷超过阔值时, HeNB判断为 UE使用 某一辅载波(辅载波 a ), 并执行步骤 502; 当 HeNB判断不需要为 UE使用某 一辅载波时, 不进行后续操作。
例如, HeNB根据当前的业务量和 /或 UE的业务质量( Quality of Service ) 判断是否需要为该 UE使用辅载波 a, 在需要为 UE使用辅载波 a时执行步骤 502; 在不需要时, 不再进行后续操作。
步骤 502, HeNB向 UE发送使用辅载波 a的载波使用消息。
HeNB向 UE发送使用辅载波 a的载波使用消息, 其中该载波使用消息用 于指示 UE使用该载波所需的参数, 例如包括辅载波带宽、 中心频率以及导频 发射方式。
由于 UE已经接入了该 HeNB的主载波,所以上述载波使用消息可以通过 HeNB的主载波发送给 UE, 例如通过无线资源控制 ( Radio Resource Control, RRC ) 消息发送。
其中, 导频发射方式的表示方式可以有多种, 例如为可以用空的 IE表示 辅载波 a结束 DTX模式开始正常发射导频。 正常发射导频例如可以为在每个 子帧都发射导频。 此时, 由于导频的发送是正常的工作模式, 所以无需通知 UE导频的发射方式, 而导频的正常发送模式不限于用空的 IE进行表示,也可 以用其他方式进行表示。可以利用空的 IE表示辅载波 a结束 DTX模式开始正 常发射导频, 是由于 UE在接收到空的 IE时, 不会改变原有的正常工作模式, 即 UE按照正常工作模式测量导频。
例如还可以用导频发射的开始时间和导频发送的持续时间表示辅载波 a 的导频发射方式。 例如还可以用辅载波 a的 DTX模式的周期表示辅载波 a的 导频发射方式。
步骤 503, HeNB发射辅载波 a的导频。 HeNB开始发射辅载波 a的导频,具体的发射方式例如可以为, 结束 DTX 模式, 转入正常工作模式, 按照正常方式发射导频; 例如还可以为按照一定的 导频发送开始时间和导频发送持续时间发射导频; 例如还可以为按照 DTX模 式的周期发射导频。
本领域普通技术人员可以理解,步骤 502与步骤 503之间没有特定的执行 顺序, 可以同时执行, 可以先执行步骤 502, 也可以先执行步骤 503。 相应的, 步骤 501中判断需要为 UE使用辅载波 a后,可以同时执行步骤 502和步骤 503, 也可以执行步骤 502, 或者执行步骤 503.
在步骤 502与步骤 503同时执行时, 步骤 502中向 UE发送的载波使用消 息中的导频发射方式要与步骤 503中导频发射方式一致。
在先执行步骤 502时, 步骤 503中导频发射方式需要与步骤 502中向 UE 发送的载波使用消息中的导频发射方式一致。
在先执行步骤 503时 , 步骤 502中向 UE发送的载波使用消息中的导频发 射方式需要与步骤 503中的导频发射方式一致。
在上述步骤完成后, UE就可以使用辅载波 a了, 进一步的, 为了更好的 使用辅载波 a传输数据, 该方法还可以包括下述步骤。
步骤 504, UE对辅载波 a进行信道质量测量。
UE按照步骤 502中载波使用消息中表示的导频发射方式接收辅载波 a的 导频, 并进行信道质量测量, 并将测量结果反馈给 HeNB。
步骤 505, HeNB重新配置辅载波 a的 DTX周期
由于上述 UE需要使用辅载波 a,所以辅载波原有的 DTX周期可能无法满 足该 UE的数据业务传输需求。 因此, HeNB需要根据 UE的数据业务传输需 求重新配置辅载波 a的 DTX周期。
进一步的, HeNB可以 据重新配置的 DTX周期,配置 UE的 DR 周期。 步骤 504与步骤 505之间没有特定的执行顺序,可以同时执行,也可以先 执行步骤 504, 或者先执行步骤 505。
通过本发明第五实施例,在 HeNB配置为多载波模式的情况下,可以通过 向 UE发送辅载波 a的载波使用消息指示 UE使用辅载波 a, 并且按照该载波 使用消息中的导频发射方式开始发射辅载波 a的导频,使得 UE可以顺利使用 该辅载波 a。

进一步的, 指示模块 603还用于向 HeNB发送靠近该 HeNB的 UE的 ID。 参照本发明的第三实施例可知,指示模块 603可以发送靠近指示,该靠近 指示不用于指示 HeNB具体采用哪种发送开销消息的方式, 仅用于指示有 UE 靠近该 HeNB;该靠近指示还可以用于指示 HeNB具体采用哪种发送开销消息 的方式。
通过本发明的第 6实施例提供的 MME, 可以在 UE靠近 HeNB时, 指示 HeNB发送开销消息, 从而使得 UE可以顺利使用 HeNB的载波, 且并不限于 HeNB配置为单载波或者多载波的模式。

其中, MME1001确定 UE1003是否接近 HeNB 1002可以通过获取 UE 1003 和 HeNB1002的位置信息, 并通过位置信息判断 UE1003接近了 HeNB1002。
MME1001 还可以通过服务小区转发的接近指示确认 UE1003 接近了 HeNB 1002。其中该接近指示为 UE1003根据自身存储的 HeNB 1002周围的 eNB 和 /或 HeNB的 ID与获取的 eNB和 /或 HeNB的 ID相同,确认 UE 1003接近了 HeNB 1002时发送的; 或者该接近指示为 UE1003根据自身存储的 HeNB1002 周围的 eNB和 /或 HeNB的小区 ID与获取的小区 ID相同, 判断 UE1003接近 了 HeNB 1002时发送的。
进一步的, MME1001还可以用于检测 UE1003是否有接入 HeNB 1002的 权限。
例如, MME1001可以在 UE1003的位置信息发生变化时, 判断 UE1003 是否有权接入 HeNB 1002, 并在判断有权接入时, 判断 UE1003 是否接近了 HeNB 1002。
例如, MME1001还可以在判断 UE 1003接近 HeNB 1002时,判断 UE 1003 是否有权接入 HeNB1002, 如果有权接入则进一步发送靠近指示, 如果没有接 入权限, 则不进行后续操作。
通过本发明的第十实施例提供的信息发送系统,可以在 UE靠近 HeNB时, 使得 HeNB发送开销消息, 从而使得 UE可以使用 HeNB的载波。
