Description

无线通信方法和设备 技术领域
本发明实施例涉及通信技术领域, 并且更具体地, 涉及一种无线通信方 法和设备。 背景技术
随着移动智能用户设备的大规模应用和无线通信带宽的需求日益增长, 无线通信领域 ^ |入新的通信制式和组网形态。在一定的地理范围内可能会同 时存在不同制式的小区, 如 GSM ( Global System of Mobile communication , 全球移动通信系统) 小区, UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统)小区或 LTE ( Long Term Evolution, 长期演进 ) 小区等, 一个 UE ( User Equipment, 用户设备)所处的位置可能同时覆盖有 多个不同制式的小区。
现有技术中, 各种制式均有独立的管理实体进行无线资源管理, 例如 GSM中的 BSC( Base Station Controller,基站控制器), UMTS中的 RNC( Radio Network Controller,无线网络控制器),和 LTE中的 eNB( evolutional Node B , 演进型基站), 分别负责各制式小区的功率控制、 信道分配和资源调度、 UE 的切换和接入控制等功能。 每种制式的小区都有各自的逻辑信道, 如 BCCH ( Broadcasting Control Channel, 广播控制信道 )和 CCCH ( Common Control Channel, 公共控制信道) 以及 TCH ( Traffic Channel, 业务信道)等, 诸如 基站控制器之类的管理实体负责这些逻辑信道的管理包括对应物理资源的 管理。 UE注册到某一制式的核心网后, 就监听该制式下的小区的 BCCH, 获取该小区接入、 寻呼、 测量控制、 小区重选等相关参数, 根据获取到该小 区的这些参数,在该小区的 CCCH上发起接入并接收响应,或者监听并响应 寻呼。
在现有技术中, 当处于空闲态的 UE在不同制式的覆盖区域内移动时, 会导致该 UE 频繁改变驻留的制式, 不断执行区域更新, 读取系统消息 ( System Information, SI ), 该 UE的耗电量增大; 此外, 频繁改变驻留的制 式会导致频繁的信令交互, 使得网络拥塞的可能性加大, 无线资源协调管理 的复杂度高, 例如, 处于空闲态的 UE从某一制式的区域移动到另一制式的 区域, 网络侧设备需要跨制式协调接入控制、 小区重选等驻留参数。 发明内容

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
应理解, 本发明实施例的技术方案可以应用于各种通信系统, 例如: GSM系统、 CDMA( Code Division Multiple Access,码分多址)系统、 WCDMA ( Wideband Code Division Multiple Access , 宽带码分多址) 系统、 GPRS ( General Packet Radio Service, 通用分组无线业务;)、 LTE系统、 LTE FDD ( Frequency Division Duplex , 频分双工) 系统、 LTE TDD ( Time Division
Duplex , 时分双工)、 UMTS、 WiMAX ( Worldwide Interoperability for
Microwave Access, 全球互联微波接入)通信系统等。
在本发明实施例中, 基站可以是 GSM 或 CDMA 中的 BTS ( Base
Transceiver Station, 基站), 也可以是 WCDMA中的 NB ( NodeB , 基站)或 者 UMTS中的 BS ( Base Station, 基站;), 还可以是 LTE中的 eNB, 等等, 本发明并不限定。
基站控制器, 可以是 GSM或 CDMA中的 BSC, 也可以是 WCDMA中 的 RNC, 还可以合并在 LTE的 eNB中。
还应理解, 在本发明实施例中, 用户设备可称之为终端 (Terminal ), MS ( Mobile Station, 移动台)、 移动终端 ( Mobile Terminal ) 等, 该用户设 备可以经 RAN ( Radio Access Network, 无线接入网 )与一个或多个核心网 进行通信, 例如, 用户设备可以是移动电话(或称为 "蜂窝" 电话)、 具有 移动终端的计算机等, 例如, 用户设备还可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置, 它们与无线接入网交换语音和 /或数据。
图 1-1至图 1-3是可应用于本发明实施例的应用场景的示意图。在图 1-1 至图 1-3 中均描述了三种不同制式的覆盖区域, 分别是 GSM区域, UMTS 区域和 LTE区域, 但仅仅是为了描述方便。 在图 1-1至图 1-3中可以包括两 种制式的区域或者更多制式的区域, 并且不限于 3GPP ( The 3rd Generation Partnership Project, 第三代合作伙伴计划) /3GPP2中规定的制式, 本发明实 施例对此并不限定。 同一制式的区域可以是 1个或多个, 例如, 图 1-1的场 景中描绘了 1个 GSM区域、 1个 UMTS区域和 1个 LTE区域, 图 1-2描绘 了 1个 GSM区域、 2个 UMTS区域和 2个 LTE区域, 以及图 1-3的场景中 描绘了 1个 GSM区域、 2个 UMTS区域和 1个 LTE区域, 本发明实施例对 此也不作限制。在图 1-1至图 1-3的场景中还描述了位于不同制式区域的 UE, 图 1-1中 GSM区域 GSM 111的 UE 114, LTE区域 LTE 112的 UE 115, UMTS 区域 UMTS 113的 UE 116; 图 1-2中 GSM区域 GSM 121的 UE 124, LTE 区域 LTE 122的 UE 125 , UMTS区域 UMTS 123的 UE 126; 以及图 1-3中 GSM区域 GSM 131的 UE 134, LTE区域 LTE 132的 UE 135, UMTS区域 UMTS 133的 UE 136。 应理解, 在图 1-1至图 1-3的场景中还可以包括更多 或更少的 UE, 还应理解, UE可以是支持一种制式的 UE, 也可以是支持多 种制式的 UE, 本发明实施例对此并不限定。 还应注意的是, 图 1-1至图 1-3 的场景中不同制式的覆盖区域中各个区域的布置方式仅仅是示例性的, 本发 明对此并不限定。
在现有的机制中,每种制式的区域都有各自的逻辑信道,例如,在图 1-1 中, 网络侧设备需要分别向 GSM区域 GSM 111 , UMTS区域 UMTS 113和 LTE区域 LTE 112广播三套独立的系统消息, 如广播一致的区域重选的优先 级和重选门限等移动性相关的参数。 由于各种制式均有独立的管理实体, 需 要对各自的广播信道进行管理, 不同制式的小区广播的移动性相关参数需要 进行协调, 因此, 管理比较复杂, 并且空口的控制信令或者移动性相关参数 等公共的信息都需要在不同制式的覆盖区域重复下发, 从而增加了信令开 销。
为了解决上述问题, 本发明实施例提供了一种无线通信方法和网络侧设 备, 不但能够降低管理复杂度, 还能够有效地减少信令的开销。
在本发明中,通过一个统一无线控制器( Single Radio Controller, SRC ), 可以实现对各种制式无线资源进行管理, 能够更高效灵活快速的使用各个制 式的无线资源。 并且 SRC 的位置可以灵活设置, 可以放置在基站侧, 也可 以作为一个单独的实体。 图 1-1场景中的 SRC 118就是一个筒单的示例。
图 2是本发明一个实施例的无线通信方法的流程图。 图 2的方法适用于 无线通信系统, 该无线通信系统中包括统一控制区域, 该统一控制区域包括 两个或两个以上不同制式的小区所覆盖的区域。
201 , 网络侧设备为统一控制区域配置统一广播控制信道( Uni-BCCH )。 其中, uni-BCCH指的是在一定的地理区域范围内, 即统一控制区域内, 对多种制式使用一个统一广播信道发送广播消息; uni-BCCH可以单独分配 一段频谱资源, 还可以配置在某种制式上, 例如, GSM 制式的小区覆盖范 围大, 可以配置在 GSM上, 此处不进行限制。
例如, 上述统一控制区域可以为图 1-1中的 GSM111 , 或者图 1-2中的 GSM121 , 或者图 1-3中的 GSM13L
其中, 网络侧设备可以为统一无线控制器 SRC, 该 SRC用于统一控制 区域内不同制式的无线资源管理, 例如, 图 1-1中的 SRC。
202, 网络侧设备在统一广播控制信道上, 向位于统一控制区域、 且驻 留在统一广播控制信道上的空闲态用户设备 UE发送广播消息。
其中, 上述广播消息可以包括以下信息中的一种或多种:
统一控制区域的区域标识, 用于 UE识别所在区域, 即用于 UE识别所 处于的统一控制区域;
统一位置区信息, 该统一位置区信息用于 UE进行位置更新判断; 统一控制区域内的至少一种制式的配置信息, 其中, 至少一种制式的配 置信息用于 UE对该至少一种制式的信号进行测量以获得测量结果, 例如,
UE对 LTE制式的覆盖区域的参考信号进行测量以获得参考信号的接收功率 或质量;
统一控制区域内的至少一种制式的公共控制信道的配置信息, 其中, 至 少一种制式的公共控制信道的配置信息用于 UE在至少一种制式的公共控制 信道中选择一种制式的公共控制信道, 并在上述选择的一种制式的公共控制 信道上发起空口连接建立的流程。
例如, 当统一控制区域包括 GSM区域时, 上述配置信息可以包括业务 信道的频段、 频点等信息; 当统一控制区域包括 UMTS/LTE区域时, 上述配 置信息可以包括业务信道的频点、 带宽等信息。
本发明实施例中, 网络侧设备为统一控制区域配置统一广播控制信道, 并在统一广播控制信道上发送广播消息, 使得处于空闲态的 UE驻留在统一 广播控制信道上监听广播消息, 从而使得 UE在统一控制区域内的不同制式 的覆盖区域内移动过程中, 无需改变驻留的制式, 从而降低了无线资源协调 管理的复杂度, 减小了信令开销, 同时降低了 UE的耗电量。
需要指出的是, 上述统一控制区域内的不同制式的小区中可以无需配置 各自制式的广播控制信道, 能够避免不同制式的小区无需对各自的广播信道 进行管理, 也无需对不同制式的小区的广播消息进行协调; 或者, 上述统一 控制区域内的不同制式的小区中配置各自制式的广播控制信道, 此时, 存在 相同的广播信息在各个不同制式的覆盖区域的重复传输, 因此, 仅采用上述 统一广播控制信道向不同制式小区覆盖下的 UE发送该相同的广播消息, 能 够进一步减少信令开销。
可选地, 在一种实施场景下, 在步骤 202之前还包括:
203, 网络侧设备为统一控制区域配置统一公共控制信道( Uni-CCCH )。
204, 网络侧设备向 UE发送统一公共控制信道的配置信息, 统一公共 控制信道的配置信息用于 UE在统一公共控制信道上发送或接收消息。
其中,该消息可以为接入请求消息,或者接入响应消息,或者寻呼消息, 此处不进行限制; 统一公共控制信道是为上述统一控制区域配置的。
其中, 向 UE发送统一公共控制信道的配置信息具体可以采用如下两种 方式:
方式一、将统一共公共控制信道的配置信息携带在上述广播消息中发送 给 UE。
方式二、 将统一共公共控制信道的配置信息携带在新增消息中发送给
UE。
需要说明的是, 位于统一控制区域的 UE可以在统一公共控制信道上向 网络侧设备发送接入请求消息, 或者接收网络侧设备发送的接入响应消息, 或者接收网络侧设备发送的寻呼消息等相关的参数信息。
其中, 步骤 204中的统一公共控制信道可以包括上行统一公共控制信道 和 /或下行统一公共控制信道, 具体地, 可以是物理信道、传输信道或逻辑信 道等。例如,上行统一公共控制信道中的 Uni-RACH( Random Access Channel, 接入信道), 下行统一公共控制信道中的响应 Uni-RACH 的 Uni-AGCH ( Access Grant Channel, 接入准许信道)或 Uni-PCH ( Paging Channel, 统 一寻呼信道), 等等。
可选地, 在上述实施场景中的第一种实现方式下, 在步骤 204之后还包 括: 网络侧设备在下行统一公共控制信道(例如 Uni-PCH信道)上向上述 UE发送寻呼消息。
可选地, 在上述实施场景中的第二种实现方式下, 在步骤 204之后还包 括:
网络侧设备在上行统一公共控制信道(例如 Uni-RACH信道)上接收位 于上述 UE发送的接入请求消息;
网络侧设备根据上述接入请求消息, 在下行统一公共控制信道(例如 Uni-AGCH信道)上向上述 UE发送接入响应消息。
其中,上述寻呼消息,接入请求消息以及接入响应消息均属于现有技术, 此处不再赘述。
可选地, 在上述实施场景中的第三种实现方式下, 当 UE接入网络后, 即在步骤 204之后还包括: 网络侧设备在上述不同制式中选择一种制式作为目标制式; 网络侧设备获取在该目标制式中为该 UE分配的传输信道的信息; 网络侧设备在下行统一公共控制信道上, 向上述 UE发送该目标制式的 传输信道的信息。
其中, 该目标制式的传输信道的信息用于上述 UE接入该目标制式的传 输信道, 并在该目标制式的传输信道上进行业务数据或控制信令的传输。 具 体地, 该目标制式的传输信道的信息可以包括对应逻辑信道、 传输信道、 和 /或物理信道的配置参数。 例如, 在目标制式为 UMTS/LTE时, 该传输信道 可以为 DTCH ( Dedicated Traffic Channel, 专用业务信道)、 CTCH ( Common Traffic Channel,公共业务信道或共享业务信道 )和 DCCH ( Dedicated Control Channel, 专用控制信道)等中的一种或多种。 在目标制式为 GSM时, 该传 输信道可以为如下 DCCH、 TCH、 PDTCH ( Packet Data Traffic Channel, 分 组数据业务信道 )和 PACCH ( Packet Associated Control Channel, 分组随路 控制信道)等中的一种或多种。 此外, 该目标制式的传输信道可以由该目标 制式的网络控制节点来分配, 也可以由 SRC来分配, 此处不进行限制。
具体地, 当上述广播消息包含统一控制区域内的至少一种制式的配置信 息时, 接入请求消息携带该至少一种制式的测量结果, 网络侧设备可以根据 该至少一种制式的测量结果, 则在上述不同制式中选择一种制式作为目标制 式包括:
才艮据上述至少一种制式的测量结果,在上述至少一种制式中选择一种制 式作为目标制式。
需要指出的是, 网络侧设备还可以根据上述 UE发起的业务类型或者上 限制。
可选地,网络侧设备可以通过寻呼消息携带目标制式的 CCCH信道的配 置信息,以便支持目标制式的 UE可以根据目标制式的 CCCH信道的配置信 息在目标制式的 CCCH信道上发起空口连接建立的流程。或者,在广播消息 中包括统一控制区域内的至少一种制式的公共控制信道的配置信息,且该至 少一种制式的公共控制信道的配置信息中存在目标制式的公共控制信道的 配置信息的情况下,网络侧设备还可以在寻呼消息中携带 CCCH信道的指示 信息, 以便 UE根据 CCCH信道的指示信息在至少一种制式的公共控制信道 的配置信息中获取目标制式的 CCCH 信道的配置信息, 根据目标制式的 CCCH信道的配置信息在目标制式的 CCCH信道上发起空口连接建立的流 程。
具体地, 如果广播消息中包含多种制式(包括目标制式)的 CCCH信道 的配置信息, 则寻呼消息中可以通过指示信息为索引的方式指示目标制式的
CCCH信道的配置消息,在目标制式的 CCCH信道上发起空口连接建立的流 程。 目标制式以 LTE制式为例, 支持 LTE制式的 UE可以根据 LTE制式的 CCCH信道的配置信息在 LTE制式的 CCCH信道上发送 RRC( Radio Resource Connection, 无线资源控制)连接请求消息, 进一步地, 网络侧设备可以在 LTE制式的 CCCH信道上发送给支持 LTE制式的 UE的 RRC连接响应消息 中携带 LTE制式的专用信道(如 DTCH信道和 DCCH信道) 的配置信息。
可选地,网络侧设备可以通过接入响应消息携带目标制式的 CCCH的配 置信息,以便支持目标制式的 UE在目标制式的 CCCH信道上发起空口连接 建立的流程。 或者, 在广播消息包括统一控制区域内的至少一种制式的公共 控制信道的配置信息,且至少一种制式的公共控制信道的配置信息中存在目 标制式的公共控制信道的配置信息的情况下, 网络侧设备还可以在接入响应 消息中携带 CCCH信道的指示信息,以便 UE根据 CCCH信道的指示信息在 至少一种制式的公共控制信道的配置信息中获取目标制式的 CCCH信道的 配置信息, 根据目标制式的 CCCH信道的配置信息在目标制式的 CCCH信 道上发起空口连接建立的流程。
具体地, 如果广播消息中包含多种制式(包括目标制式)的 CCCH信道 的配置信息, 则接入响应消息中可以通过指示信息为索引的方式指示目标制 式的 CCCH信道的配置信息, 以便支持目标制式的 UE在目标制式的 CCCH 信道上发起空口连接建立的流程。 目标制式以 LTE制式为例, 支持 LTE制 式的 UE可以根据 LTE制式的 CCCH信道的配置信息在 LTE制式的 CCCH 信道上发送 RRC连接请求消息, 进一步地, 网络侧设备可以在 LTE制式的 CCCH信道上发送给支持 LTE制式的 UE的 RRC连接响应消息中携带 LTE 制式的专用信道(如 DTCH信道和 DCCH信道) 的配置信息。
在现有机制中, 网络侧设备需要分别向不同制式的覆盖区域广播各自制 式的公共控制信道的配置信息, 驻留在不同制式的覆盖区域的 UE需要在各 自驻留的制式上完成接入并建立业务信道后才能切换到其他制式的业务信 道上进行业务, 无法实现业务跨制式的快速建立。 另外, 处于空闲 (Idle ) 模式下的 UE需要采用多种独立的流程进行接入, UE必须完成某一制式的 CCCH流程才能进入另一制式, 从而无法快速将 UE转移到其他制式进行分 流。
在本发明实施例的上述实施场景中, 网络侧设备为统一控制区域配置统 一广播控制信道, 并在统一广播控制信道上发送广播消息, 使得处于空闲态 的 UE驻留在统一广播控制信道上监听广播消息, 从而使得 UE在统一控制 区域内的不同制式的覆盖区域内移动过程中, 无需改变驻留的制式, 从而降 低了无线资源协调管理的复杂度, 减小了信令开销, 同时降低了 UE的耗电 量; 此外, 网络侧设备通过配置统一公共控制信道, 使得 UE能够快速接入 网络, 同时能够实现快速跨制式分流, 满足业务需求, 减小时延。
可选地, 在另一种实施场景中, 上述广播消息包括统一位置区信息, 一 个统一位置区可以包含一个或者多个统一控制区域。统一位置区信息用于位 于统一控制区域的 UE进行区域更新判断,区域更新可以包括 LAU( Location Area Update, 位置区更新), RAU ( Routing Area Update, 路由区更新)或 TAU ( Tracking Area Update , 跟踪区更新 )等。
例如, 如图 3所示, 网络侧设备 31在统一广播控制信道上广播的覆盖 的范围为 GSM 301的覆盖范围, 即第一统一区域信息; 网络侧设备 32在统 一广播控制信道上广播的覆盖的范围为 GSM 305的覆盖范围, 即第二统一 区域信息。 第一统一区域和第二统一区域为不同的区域。 UE 304位于 GSM 区域 GSM 301 ,从网络侧设备 31接收的广播的统一区域信息为 GSM 301的 覆盖范围, 当 UE 304从 GSM 301移动到 LTE区域 LTE 302或者从 LTE 302 移动到 UMTS区域 UMTS 303时, UE 304不进行位置区更新。 当 UE 304 从 LTE 302移动到 GSM 305 , 超出了 GSM 301的覆盖范围, UE 304进行位 置区更新。 UE 304进行位置区更新后, 位于 GSM 305 , 从网络侧设备 32接 收的广播的统一区域信息为 GSM 305的覆盖范围,如果 UE 304从 GSM 305 移动到 LTE 306, 或者从 LTE 306移动到 UMTS307, 或从 GSM 305移动到 者 UMTS307, UE 304都不进行位置区更新。
应理解上述实施场景仅仅是示例性的, 而非要限制本发明的范围。
在现有技术中, 驻留在某种不连续覆盖的制式上时, 由于 UE的移动, 导致 UE移出了该制式的小区的覆盖, 则 UE需要频繁改变驻留的制式, 不 断要执行区域更新, 且不断的读取系统消息 (System Information, SI ), 造 成耗电, 并且频繁的信令会导致网络拥塞的可能性加大。 CN ( Core Net, 核 心网)要管理 UE在不同制式下的移动性, 通过管理 RA/LA//TA表(list ) 来尽量避免 LAU/RAU/TAU产生的信令, 对于 CN, 不同制式的移动性区域 RA/LA//TA的管理复杂度高, 规划困难。
在本发明的上述另一种实施场景中, 当 UE移动导致频繁改变驻留的制 式时, 避免不断地执行位置更新, 只有在超出了一定的地理范围时才进行位 置区更新, 从而避免了不断地读取各种制式小区的 SI, 降低 UE的耗电量, 并且降低了信令的频繁交互而导致网络拥塞的可能性, 以及降低 CN管理的 复杂度。
可选地, 作为另一个实施例, 在步骤 201中, 网络侧设备可以以带内方 式在不同制式区域中的覆盖范围最广的制式上(例如在图 1-1至图 1-3场景 中的 GSM制式) 配置统一广播控制信道。 或者, 还可以以带外方式(不在 任一制式上)配置统一广播控制信道, 即单独分配一段频谱资源作为统一广 播控制信道。 应理解, 本发明实施例对此并不限定。
图 4是本发明另一个实施例的无线通信方法的流程图,适用于无线通信 系统, 该无线通信系统中包括统一控制区域, 该统一控制区域包括两个或两 个以上不同制式的小区所覆盖的区域, 该统一控制区域配置有统一广播控制 信道。 图 4的方法由 UE执行(如图 1中的 UE 105 ), 并与图 2的方法相对 应, 因此将适当省略与图 2的实施例重复的描述。
401 , 处于统一控制区域的 UE在处于空闲态时驻留在统一广播控制信 道上。
其中, UE位于统一控制区域。
402, UE在统一广播控制信道上接收网络侧设备发送的广播消息。
本发明实施例中, UE在处于空闲态时驻留在统一广播控制信道上, 在 统一广播控制信道上接收网络侧设备发送的广播消息, 即 UE在处于空闲态 时驻留在统一广播控制信道上监听广播消息, 使得 UE在统一控制区域内的 不同制式的覆盖区域内移动过程中,无需改变驻留的制式,减小了信令开销, 降氐了 UE的耗电量。
可选地,上述广播消息包括统一控制区域的区域标识,上述方法还包括: UE根据统一控制区域的区域标识识别所在区域; 和 /或,
上述广播消息包括统一位置区信息, 上述方法还包括: UE根据统一位 置区信息进行位置更新判断; 和 /或,
上述广播消息包括统一控制区域内的至少一种制式的配置信息, 上述方 法还包括: UE根据上述至少一种制式的配置信息对上述至少一种制式的信 号进行测量获得测量结果; 和 /或,
上述广播消息包括统一控制区域内的至少一种制式的公共控制信道的 配置信息, 上述方法还包括: UE根据上述至少一种制式的公共控制信道的 配置信息在上述至少一种制式的公共控制信道中选择一种制式的公共控制 信道, 并在上述选择的一种制式的公共控制信道上发起空口连接建立的流 程。
其中, 上述位置更新可以包括 LAU更新, RAU更新或 TAU更新等。 UE进行位置更新的例子如上所述, 此处不再赘述。 当 UE的移动, 导致频 繁改变驻留的制式时, 不会不断地执行注册或位置更新, 只有在超出了一定 的统一区域时才进行注册或位置区更新, 因此, 不会不断地读取各种制式小 区的 SI, 从而降低 UE的耗电量, 并且降低了信令的频繁交互而导致网络拥 塞的可能性, 以及降低 CN管理的复杂度。 另外, 不同制式小区中各个制式 小区的配置信息包括小区重选的优先级和重选门限等移动性相关的参数, 采 用统一广播控制信道广播给位于不同制式小区的 UE, 不会导致一致的配置 信息重复下发, 提高系统消息广播的效率, 降低时延, 无需对不同制式小区 的移动性相关参数进行协调, 从而降低移动性管理的复杂度。
可选地, 在一种实施场景下, 当网络侧设备为统一控制区域配置统一公 共控制信道时, 上述方法还可以包括:
403 , UE接收网络侧设备发送的统一公共控制信道的配置信息。

404、 UE根据上述配置信息在统一公共控制信道上接收或发送消息。 其中,该消息可以为接入请求消息,或者接入响应消息,或者寻呼消息, 此处不进行限制。
具体地, 位于不同制式区域的 UE在统一公共控制信道上向网络侧设备 发送接入请求消息, 或者接收网络侧设备发送的接入响应消息, 或者接收网 络侧设备发送的寻呼消息等相关的参数信息。
其中,统一公共控制信道可以包括上行统一公共控制信道和 /或下行统一 公共控制信道, 具体地, 可以是物理信道、 传输信道或逻辑信道等。 例如, 上行统一公共控制信道中的 Uni-RACH信道,下行统一公共控制信道中的响 应 Uni-RACH信道的 Uni-AGCH信道或 Uni-PCH信道, 等等。
可选地, 在上述实施场景的第一种实现方式下, 当统一公共控制信道包 括下行统一公共控制信道时, 在步骤 403之后, 上述方法还可以包括: UE在下行统一公共控制信道上接收网络侧设备发送的寻呼消息。
可选地, 在上述实施场景的第二种实现方式下, 当统一公共控制信道包 括下行统一公共控制信道和上行统一公共控制信道时, 在步骤 403之后, 上 述方法还可以包括:
UE在上行统一公共控制信道上向网络侧设备发送接入请求消息;
UE在下行统一公共控制信道上向接收网络侧设备根据接入请求消息发 送接入响应消息。
可选地, UE在下行统一公共控制信道上接收网络侧设备发送的、 在目 标制式中为 UE分配的传输信道的信息; UE根据目标制式的传输信道的信 息接入目标制式的传输信道,在目标制式的传输信道上进行业务数据或控制 信令的接收或发送。
其中, 目标制式为不同制式中任一种; 传输信道的信息可以包括对应逻 辑信道、 传输信道、 和 /或物理信道的配置参数。
可选地, 当广播消息包括统一控制区域内的至少一种制式的配置信息 时, 接入请求消息携带上述至少一种制式的测量结果, 上述至少一种制式的 测量结果用于网络侧设备在该至少一种制式中选择一种制式作为目标制式。
可选地, 在上述第一种实施方式下, 寻呼消息可携带目标制式的 CCCH 信道的配置信息, UE可以根据目标制式的 CCCH信道的配置信息在目标制 式的 CCCH信道上发起空口连接建立的流程。或者,在广播消息包括统一控 制区域内的至少一种制式的公共控制信道的配置信息,且该至少一种制式的 公共控制信道的配置信息中存在目标制式的公共控制信道的配置信息的情 况下, 寻呼消息可携带 CCCH信道的指示信息, UE根据指示信息在至少一 种制式的配置信息中获取目标制式的 CCCH信道的配置信息,根据目标制式 的 CCCH信道的配置信息在目标制式的 CCCH信道上发起空口连接建立的 流程。
在上述第二种实现方式下,接入响应消息可携带目标制式的 CCCH信道 的配置信息,UE根据目标制式的 CCCH信道的配置信息在目标制式的 CCCH 信道上发起空口连接建立的流程。 或者, 在广播消息包括统一控制区域内的 至少一种制式的公共控制信道的配置信息,且该至少一种制式的公共控制信 道的配置信息中存在目标制式的公共控制信道的配置信息的情况下,接入响 应消息可携带 CCCH信道的指示信息, UE可根据 CCCH信道的指示信息在 至少一种制式的配置信息中获取目标制式的 CCCH信道的配置信息,根据目 标制式的 CCCH信道的配置信息在目标制式的 CCCH信道上发起空口连接 建立的流程。
本发明实施例的上述实施场景中, UE在空闲状态驻留在统一广播控制 信道上, 并在统一广播控制信道上接收广播消息, 使得 UE在统一控制区域 内的不同制式区域的移动过程中, 无需改变驻留的制式, 从而减小了信令开 销, 降低 UE的耗电量; 此外, 避免了 UE在除目标制式之外的其它制式上 建立传输信道, 再通过切换等方式进入目标制式区域的复杂处理流程, 而是 通过公共控制信道建立目标制式的传输信道, 实现快速跨制式分流, 满足业 务需求, 降低时延。
图 5是本发明一个实施例的无线通信方法的过程的示意性流程图。 501 , 网络侧设备在统一广播控制信道上向 UE发送广播消息。
其中,上述广播消息以及统一广播控制信道的相关描述参见图 2所示的 实施例。
其中, 上述统一广播控制信道配置在统一控制区域内, 统一控制区域包 括两个或两个以上不同制式的小区所覆盖的区域,且统一控制区域配置有统 一广播控制信道。
需要指出的是, 上述广播消息包括统一公共控制信道的配置信息, 且统 一公共控制信道包括下行统一公共控制信道和上行统一公共控制信道。
其中, 统一公共控制信道的配置信息(如频率、 宽带和同步信息等)可 以包含在广播消息中, UE通过广播消息获得, 应理解, 本发明实施例对此 并不限定, 网络侧设备可以通过其它方式将配置的统一公共控制信道的配置 消息发送给 UE。 502, UE在上行统一公共控制信道上向网络侧设备发送接入请求消息。 具体地, UE可以在对应的上行统一公共控制信道(例如 Uni-RACH信 道)上向网络侧设备发送接入请求消息。 位于统一控制区域的一个或多个 UE可以使用同一个 Uni-RACH信道。
可选地, 当广播消息包含统一控制区域内的至少一种制式的配置信息 时, UE可以根据至少一种制式的配置信息对至少一种制式的信号进行测量, 并在接入请求消息中携带上述测量结果。
503 , 网络侧设备在下行统一公共控制信道上向 UE发送接入响应消息。 其中,上述接入响应消息携带为 UE分配的目标制式的传输信道的信息。 可选地, UE可以在步骤 501 中的广播消息中接收下行统一公共控制信 道的配置消息 (如频率、 宽带和同步信息等), 在对应的下行统一公共控制 信道(例如 Uni-AGCH信道)上接收网络侧设备发送的接入响应消息。

将该传输信道的信息携带在上述接入响应消息中,并在下行统一公共控 制信道上将上述接入响应消息发送给 UE。
例如, 网络侧设备可以根据接入的 UE所支持制式的情况(例如业务的 需求或测量结果中各个制式区域的运行状况等), 或者 UE发起的业务的需 求(如带宽、 时延等), 或者各个制式区域的运行状况(如负载等), 或者各 制式区域的信号质量等, 确定后续的业务在哪一种制式上进行, 并为 UE分 配目标制式的传输信道, 从而使得 UE能够快速转移到该制式区域上, 实现 快速跨制式分流, 满足业务需求, 降低时延。

在本发明实施例的上述实施场景中, 网络侧设备为统一控制区域配置统 一广播控制信道, 并在统一广播控制信道上发送广播消息, 使得处于空闲态 的 UE驻留在统一广播控制信道上监听广播消息, 从而使得 UE在统一控制 区域内的不同制式的覆盖区域内移动过程中, 无需改变驻留的制式, 从而降 低了无线资源协调管理的复杂度, 减小了信令开销, 同时降低了 UE的耗电 量; 此外, 网络侧设备通过配置统一公共控制信道, 使得 UE能够快速接入 网络, 同时能够实现快速跨制式分流, 满足业务需求, 减小时延。
图 13 是本发明另一个实施例的用户设备的结构框图。 该用户设备 UE 位于统一控制区域, 该统一控制区域包括两个或两个以上不同制式的小区所 覆盖的区域, 该统一控制区域配置有统一广播控制信道, 该用户设备 1300 包括处理器 1301和接收器 1302。
处理器 1301用于在处于空闲态时控制用户设备 1300驻留在统一控制区 域的统一广播控制信道上;
接收器 1302用于在处理器 1301控制用户设备 1300驻留的统一广播控 制信道上接收网络侧设备发送的广播消息。
其中, UE位于统一控制区域, 统一控制区域包括两个或两个以上不同 制式的小区所覆盖的区域。
本发明实施例中, UE在处于空闲态时驻留在统一广播控制信道上, 在 统一广播控制信道上接收网络侧设备发送的广播消息, 即 UE在处于空闲态 时驻留在统一广播控制信道上监听广播消息, 使得 UE在统一控制区域内的 不同制式的覆盖区域内移动过程中,无需改变驻留的制式,减小了信令开销, 降氐了 UE的耗电量。
用户设备 1300可实现图 2至图 8的实施例中涉及用户设备的操作, 因 此为避免重复, 不再详细描述。

从广播消息中获取统一公共控制信道的配置信息。
具体地,统一公共控制信道可以包括下行统一公共控制信道和 /或上行统 一公共控制信道。 具体可以是物理信道、 传输信道或逻辑信道等。 例如, 上 行统一公共控制信道中的 Uni-RACH信道,下行统一公共控制信道中的响应 Uni-RACH信道的 Uni-AGCH信道或 Uni-PCH信道, 等等。
可选地, 当统一公共控制信道包括下行统一公共控制信道时, 接收器 1302还可以用于在下行统一公共控制信道上接收寻呼消息。

处理器 1301还可以用于根据目标制式的传输信道的信息在目标制式的 传输信道上进行业务数据或控制信令的接收或发送。 其中, 目标制式为上述 不同制式中任一种。
其中, 网络侧设备可以将上述目标制式的传输信道的信息携带在上述寻 呼消息或者接入响应消息中发送给 UE。
可选地,在一种实现方式下,寻呼消息可以携带目标制式的 CCCH信道 的配置信息, 处理器 1301还可以用于根据目标制式的 CCCH信道的配置信 息在目标制式的 CCCH信道上发起空口连接建立的流程。
或者,在广播消息还包括统一控制区域内的至少一种制式的公共控制信 道的配置信息,且至少一种制式的公共控制信道的配置信息中存在目标制式 的公共控制信道的配置信息的情况下,寻呼消息可以携带 CCCH信道的指示 信息, 处理器 1301 还可以用于根据该指示信息在至少一种制式的公共控制 信道的配置信息中获取目标制式的 CCCH信道的配置信息,用于根据目标制 式的 CCCH信道的配置信息在目标制式的 CCCH信道上发起空口连接建立 的流程。
在另一种实现方式下,接入响应消息可以携带目标制式的 CCCH信道的 配置信息, 处理器 1301还可以用于根据目标制式的 CCCH信道的配置信息 在目标制式的 CCCH信道上发起空口连接建立的流程。
或者,在广播消息包括统一控制区域内的至少一种制式的公共控制信道 的配置信息,且至少一种制式的公共控制信道的配置信息中存在目标制式的 公共控制信道的配置信息的情况下, 处理器 1301还可以用于根据该指示信 息在至少一种制式的公共控制信道的配置信息中获取目标制式的 CCCH信 道的配置信息, 发射器 1303还可以用于根据目标制式的 CCCH信道的配置 信息在目标制式的 CCCH信道上发起空口连接建立的流程。
本发明实施例的上述实施场景中, UE在空闲状态驻留在统一广播控制 信道上, 并在统一广播控制信道上接收广播消息, 使得 UE在统一控制区域 内的不同制式区域的移动过程中, 无需改变驻留的制式, 从而减小了信令开 销, 降低 UE的耗电量; 此外, 避免了 UE在除目标制式之外的其它制式上 建立传输信道, 再通过切换等方式进入目标制式区域的复杂处理流程, 而是 通过公共控制信道建立目标制式的传输信道, 实现快速跨制式分流, 满足业 务需求, 降低时延。
