Description

寻呼闲置模式的终端的方法和先进网元设备 技术领域 本发明涉及通信领域, 具体而言, 涉及一种寻呼闲置模式的终端的方法 和先进网元设备。 背景技术 在无线通信系统中, 通过基站 (Base Station, 简称为 BS ) 利用指定的 无线信道在一定地理范围内提供无线覆盖, 这个地理范围称为小区。 通常, 从理论上讲, 基站位于小区中央。 按照覆盖范围的大小, 基站可以分成宏基 站 ( Macro BS ), ^啟基站 ( PICO BS ), 啟基站 ( FEMTOCELL BS )„ jt匕夕卜, 为了扩展覆盖或者扩展容量, 在移动站和基站之间可以放置一个或多个中继 站。 对于移动站来说, 中继站就相当于一个基站。 移动站从一个小区移动到 另一个小区时, 为了保持通信, 就需要进行切换。 居所支持的通信协议, 基站 /中继站可以分为先进控制站和传统控制 站, 先进控制站是指支持先进通信协议的基站 /中继站 ( Advanced Base Station/Advanced Relay Station , 简称为 AB S/ARS ) , 传统控制站是指可以支 持传统通信协议的基站 /中继站 ( Yardstick Base Station/Yardstick Relay Station, 简称为 YBS/YRS , 或 Legacy Base Station, 简称为 Legacy BS )。 在 考虑兼容性的技术中, 对于先进控制站, 又将其帧分成了第一区域和第二区 域。 第二区域可以支持传统通信协议, 因此又可以称为传统区域, 第一区域 只能支持先进通信协议, 因此又可以称为先进区域。 类似地, 对于移动站, 也可以分为先进移动站 (Advanced Mobile Station, 简称为 AMS ) 和传统移 动站 ( Yardstick Mobile Station, 简称为 YMS , 或 Legacy Mobile Station, 简 称为 Legacy MS ), 先进移动站可以工作在第一区域或第二区域, 而传统移动 站只能工作在第二区域。 对于传统移动站而言, 先进控制站的第二区域相当 于一个传统控制站。 此外, 先进移动站接入传统控制站工作时, 对于传统控 制站而言, 该先进移动站就是一个传统移动站。 此外, 先进控制站也可以只 支持先进通信协议, 此时, 先进控制站可以只有第一区域。 以下以 IEEE802.16标准为例来进行进一步描述。 IEEE802.16标准是 4十 对微波频段提出的一种先进的空中接口标准, 其制订了物理层 (PHY ) 和媒 质接入控制层(Media Access Control, 简称为 MAC )的规范。 包含中继结构 的 IEEE802.16m是目前 IEEE802.16标准中最先进的标准技术, IEEE802.16m (以下简称 16m ) 建立在 IEEE802.16e (以下简称 16e )、 IEEE802.16j (以下 简称 16j ) 等传统标准的基础上。 基于以上描述, 先进控制站 (支持 16m协议的基站 /中继站) 能够兼容 支持传统移动站(支持 16e协议的移动站;), 同样地, 先进移动站(支持 16m 协议的移动站) 也应该能够接入传统控制站 (支持 16e的基站或支持 16j的 中继站)。 第一区 i或(也称为先进区 i或, 16m zone, 简称为 MZone )支持 16m 定义的先进的通信协议, 第二区域(也称为传统区域, Legacy Zone, 简称为 LZone ) 可以支持 16e/16j的协议。 jt匕夕卜, 先进控制站也可以只有 MZone。 一般来说, 当系统中的控制站从传统控制站演进到先进控制站时, 控制 站所连接的网络(也称为接入月艮务网络, access service network, ASN ) 也会 相应的从传统网络演进到先进网络。 但是, 在实际的系统中, 由于控制站和 网络的发展速度不一定同步, 或者, 市场发展要求尽快使用先进技术, 就会 出现控制站是先进控制站, 而接入服务网络是传统网络的情况,如图 1所示。 此时, 如果在先进终端和先进控制站的空口直接使用先进的通信协议, 而不 做任何改变, 就有可能在后续的与传统网络的通信过程中出现问题。 例如, 为了省电, 移动终端 (也称为终端, 移动站) 可进入闲置 (Idle ) 模式, 此后移动终端只是在离散的间隔周期性的接收下行广播数据, 并且在 多个控制站之间移动过程中, 仅在需要时向控制站更新位置信息, 而无需进 行切换和网络重进入。 传统控制站 /终端和先进控制站 /终端在 Idle模式的处 理上存在较大差异。 以 16e和 16m标准为例, 移动终端寻呼监听的处理方法 在两种标准中完全不同。 支持 16e协议的控制站分配给移动终端的寻呼周期 ( Paging Cycle )以及寻呼位移( Paging Offset )都是以帧为单位, 而支持 16m 协议的控制站分配给移动终端的寻呼周期以及寻呼位移都是以超帧为单位, 一个超帧中一般含有 4个帧。 发明人发现: 在现有的控制站连接传统网关的情况下, 无论是 16e还是 16m的控制站, 寻呼控制器都会为其月艮务范围内的移动终端分配以帧为单位 的寻呼周期以及寻呼位移, 这样, 在先进控制站连接传统接入网络时, 闲置 模式的终端无法正常工作。 发明内容 本发明的主要目的在于提供一种寻呼闲置模式的终端的方法和先进网元 设备, 以至少解决现有技术中在先进控制站连接传统接入网络时, 闲置模式 的终端无法正常工作的问题。 根据本发明的一个方面, 提供了一种寻呼闲置模式的终端的方法, 其包 括: 先进网元设备将所要寻呼的终端的传统寻呼信息映射成先进寻呼信息; 先进网元设备使用先进寻呼信息寻呼所要寻呼的终端。 根据本发明的另一方面, 提供了一种先进网元设备, 其包括: 映射单元, 用于将所要寻呼的终端的传统寻呼信息映射成先进寻呼信息; 寻呼单元, 用 于使用先进寻呼信息寻呼所要寻呼的终端。 通过本发明, 先进网元设备将进入闲置模式的终端所对应的传统寻呼信 息映射成先进寻呼信息, 从而使得处于闲置模式的终端能适应系统的演进正 常工作, 并实现了省电的目的, 解决先进控制站连接传统接入网络时闲置模 式的终端无法正常工作的问题。 附图说明 此处所说明的附图用来提供对本发明的进一步理解, 构成本申请的一部 分, 本发明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的 不当限定。 在附图中: 图 1是根据相关技术的系统演进网络的示意图; 图 2是才艮据本发明实施例的寻呼闲置模式的终端的方法的一种优选流程 图; 图 3是根据本发明实施例的终端请求进入闲置模式, 先进控制站为终端 分配以超帧为单位的寻呼周期和寻呼位移的流程图; 图 4是根据本发明实施例的先进控制站主动要求终端进入闲置模式, 先 进控制站为终端分配以超帧为单位的寻呼周期和寻呼位移的流程图; 图 5是根据本发明实施例的先进控制站在第一区域对终端进行寻呼的流 程图; 图 6是根据本发明实施例的处于闲置模式的终端监听寻呼信息并进行相 应处理的流程图; 图 7是根据本发明实施例的先进网元设备的结构示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 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。 实施例 1 图 2是根据本发明实施例的寻呼闲置模式的终端的方法的流程图, 其包 括如下步 4聚: S202, 先进网元设备将所要寻呼的终端的传统寻呼信息映射成先进寻呼 信息;

若是, 终端进入寻呼监听间隔, 接收并解析超帧中的寻呼组标识信息消息, 其中, 寻呼监听间隔的长度为一个超帧的时长 (一般为 4 帧的长度)(步骤 S608 )。 终端从所监听的超帧中解析其第一帧包含的寻呼组信息消息中的时 间域哈希参数 m, 并计算终端需要解析的寻呼广播消息所在的帧号 (步骤 S610 )。 终端使用计算得到的帧号解析对应帧包含的寻呼广播消息(步骤 S612 ), 然后判断接收到的寻呼广播消息中是否包含有与自己匹配的去注册标识符, 即判断本终端是否被寻呼 (步骤 S614 )。 如果终端被寻呼 (即寻呼广播消息 中包含有与自己匹配的去注册标识符),则终端使用寻呼消息中的指示进行位 置更新或是网络重入的操作 (步骤 S618 )。 如果终端没有被寻呼, 则终端计 算进入寻呼监听间隔的超帧号 (步骤 S616 ), 转至步骤 S606, 进入寻呼不可 及状态。 此外, 当终端有数据需要发送的情况下, 终端可随时进行网络重入, 提前结束闲置模式。 实施例 3 本实施例中与实施例 2基本相同, 不同之处在于, 在先进控制站主动要 求终端进入闲置模式。在这种情况下,先进控制站希望终端进入闲置模式时, 由先进控制站主动向寻呼控制器交互分配给该终端的寻呼组标识, 寻呼控制 器标识符、 寻呼周期及寻呼位移 (步骤 S402 ), 如图 4所示。 其中寻呼周期 和寻呼位移均以帧为计数单位。 先进控制站 居如下公式计算以超帧为单位 的寻呼周期和寻呼位移 (步骤 S404 )。 paging cycle" = floor (paging cycle 14) paging offset* = floor (paging offset 14) 其中, p 'wg qyc/e表示以†贞为计数单位的寻呼周期, paging cycle*表示以 超帧为计数单位的寻呼周期, paging ¾^et表示以帧为计数单位的寻呼位移, paging offset"表示以超帧为计数单位的寻呼位移,所述超帧所包含的帧的数目 为 4。 在 WiMAX系统中, 16m标准规定可分配给终端的寻呼周期为 8个超帧, 16个超帧, 32个超帧, 64个超帧, 128个超帧, 256个超帧, 512个超帧。 类似的, 目前 16m D6版本中规定的可分配给终端的寻呼位移的字段长度为 6个比特, 因此以超帧为单位的寻呼位移只能位于 0〜63个超帧的范围内。 因 此通过上述公式计算出以超帧为单位的寻呼周期和寻呼位移后, 先进控制站 进一步选择小于或等于 "^ ^^ (和 /或^^ "^ ^ ) 的最大的可选寻呼 周期 (和 /或寻呼位移) 作为分配给终端的寻呼周期 (和 /或寻呼位移)。 例如, 寻呼控制器分配给终端的以帧为单位的寻呼周期为 200个帧, 才艮 据上述公式可得以超帧为单位的寻呼周期为 50个超帧, 而根据 16m空口可 选寻呼周期的限制, 先进控制站选择 32 个超帧作为终端的寻呼周期。 如果 寻呼控制器分配给终端的以帧为单位的寻呼位移为 120个帧, 则才艮据上述公 式可得以超帧为单位的寻呼位移为 30个超帧, 而根据 16m空口寻呼位移只 能位于 0〜63个超帧的范围内的限制, 先进控制站可取 30个超帧作为分配给 终端的寻呼位移。 先进控制站确定了可分配给终端的以超帧为单位的寻呼周期和寻呼位移 后, 发送包含有寻呼组标识、 寻呼控制器标识符、 寻呼周期及寻呼位移的去 注册响应消息给该终端, 以通知终端进入闲置模式 (步骤 S406 ), 其中, 去 注册响应消息中的寻呼周期和寻呼位移均以超帧为计数单位。 如果先进控制站接收到寻呼控制器发送的寻呼通知消息, 如图 4所示, 先进控制站将所需寻呼终端的以帧为单位寻呼周期及寻呼位移转换成以超帧 为单位的 p g cycle*和 p g °ffset* , 然后进一步选择小于或等于 Paging cycle (和 ^ paging offset* )的最大可选寻呼周期(和 /或寻呼位移)作 为寻呼终端的寻呼周期 (和 /或寻呼位移)。 先进控制站使用以超帧为单位的寻呼周期和寻呼位移计算寻呼终端的超 帧号, 并在对应的超帧内包含所寻呼终端的信息。 进一步的, 先进控制站还 要使用终端对应的寻呼组的时间域哈希参数 m 以及终端的寻呼标识确定发 送包含该终端信息的寻呼广播消息对应的帧号, 并在计算得到的超帧内对应 的帧上发送的寻呼广播消息中包含该终端的信息。 终端接收去注册响应消息, 如图 5所示, 从中获取以超帧为单位的寻呼 周期以及寻呼位移信息, 并使用所获取的寻呼周期以及寻呼位移信息计算进 入寻呼监听间隔的超帧号 Ns rfmme 计算可釆用如下公式: N sup erframe mod paging cycle = paging offset 终端计算得到寻呼监听超帧号后, 进入闲置模式的寻呼不可及状态, 直 到先进控制站发送与寻呼监听超帧号相同的超帧, 此时终端进入寻呼监听间 隔, 寻呼监听间隔的长度为一个超帧的时长 (一般为 4 帧的长度)。 终端从 所监听的超帧中解析其第一帧包含的寻呼组信息消息中的时间域哈希参数 m, 并计算终端需要解析的寻呼广播消息所在的帧号; 终端使用计算得到的帧号解析对应帧包含的寻呼广播消息, 然后判断接 收到的寻呼广播消息中是否包含有与自己匹配的去注册标识符, 即判断本终 端是否被寻呼。 如果终端被寻呼 (即寻呼广播消息中包含有与自己匹配的去 注册标识符),则终端根据寻呼消息中的指示进行位置更新或是网络重入的操 作。 如果终端没有被寻呼, 则终端计算进入寻呼监听间隔的超帧号, 进入寻 呼不可及状态。 此外, 当终端有数据需要发送的情况下, 终端可随时进行网 络重入, 提前结束闲置模式。 实施例 4 在本实施例中, 先进控制站提供了网络侧以帧为单位的寻呼信息 (或寻 呼参数) 与空口以超帧为单位的寻呼信息的映射方法。 简单来说, 先进控制 站将网络侧寻呼参数 (以帧为单位) 与空口侧寻呼参数 (以超帧为单位)相 互映射 (或称为转换), 具体地, 包括以下两种情况: 1 ) 先进控制站收到来自 (网络侧)传统网关 (或传统寻呼控制器 PC ) 的传统的寻呼参数时, 先进控制站将其映射成以超帧为单位的 (空口) 寻呼 参数, 并将其发送给终端或者用于寻呼所要寻呼的终端 (即计算发送寻呼消 息的超帧号)。 优选的, 控制站将以超帧为单位的 (空口) 寻呼参数发送给终端的步骤 可以 出现在不同场景下: 在终端进入闲置模式时, 控制站使用 AAI_DREG-RSP消息发送以超帧为单位的寻呼参数; 或者, 在终端进行位置 更新时, 控制站使用 AAI_RNG-RSP消息发送以超帧为单位的寻呼参数。 具 体的映射 (换算) 方法可参考实施例 1至 3的方法。
2 ) 先进控制站接收到来自 (空口侧) 终端的先进寻呼参数 (以超帧为 单位) 时, 先进控制站将其映射成以帧为单位的传统寻呼参数, 并将其发送 给(网络侧) 的传统网关 (或传统寻呼控制器)。 优选的, 先进控制站可以在以下不同场景下执行上述映射: 在终端进入 闲置模式 (或称为终端去注册时 ), 先进控制站接收到来自终端的 AAI DREG-REQ消息, 其中,该 AAI_DREG-REQ消息可以携带终端请求的 先进寻呼参数; 或者, 在终端进行位置更新时, 先进控制站收到来自终端的 AAI RNG-REQ消息, 其中, 该 AAI_DREG-REQ消息可以携带终端请求改 变的先进寻呼参数。 具体的映射 (换算) 方法可以包括: 先进控制站将收到的来自终端的先 进寻呼参数 (包括寻呼周期和 /或寻呼位移)乘上预定的值得到以帧为单位的 寻呼参数。 优选的, 预定的值表示述超帧所包含的帧的数目, 例如, 4。 优选地, 如果网络侧规定了传统寻呼参数的可选值, 则先进控制站可将 此以帧为单位的寻呼参数映射到规定的可选值中大于该参数的最小的可选值 (或规定的可选值中小于该参数的最大的可选值, 或最接近的值)。 实施例 5 本发明还提供了一种先进网元设备的实施例,其可以釆用上述实施例 1-3 中的寻呼方法对处于闲置模式的终端进行寻呼。 图 7是根据本发明实施例的先进网元设备的结构示意图, 其包括: 映射 单元 702 , 用于将所要寻呼的终端的传统寻呼信息映射成先进寻呼信息; 寻 呼单元 706 , 与映射单元 702连接, 用于使用所述先进寻呼信息寻呼所述所 要寻呼的终端。 通过本发明, 先进网元设备将终端所对应的传统寻呼信息映射成先进寻 呼信息, 并使用该先进寻呼信息可以寻呼到终端, 从而使得终端能适应系统 的演进正常工作, 并实现了省电的目的, 解决先进控制站连接传统接入网络 时闲置模式的终端无法正常工作的问题。 优选的, 所述传统寻呼信息包括: 以帧为计数单位的寻呼周期和寻呼位 移; 所述先进寻呼信息包括: 以超帧为计数单位的寻呼周期和寻呼位移。 通 过本实施例中对传统寻呼信息和先进寻呼信息的限定, 可以准确地进行上述 的映射。 优选的, 所述映射单元包括 702 : 第一映射模块 7021 , 用于按照如下公 式将终端的以帧为计数单位的寻呼周期映射成以超帧为计数单位的寻呼周 期: paging cycle" = floor (paging cycle I q) , 其中, paging cycle表示以†贞为计数 单位的寻呼周期, ^^"g C ^表示以超帧为计数单位的寻呼周期, q表示所 述超帧所包含的帧的数目; 第二映射模块 7022 , 用于按照如下公式将终端的 以帧为计数单位的寻呼位移映射成以超帧为单位的寻呼位移: paging offset" = floor (paging offset I q) , 其中, PaSing G "表示以帧为计数单位 的寻呼位移, PaSing °ffset"表示以超帧为计数单位的寻呼位移, q表示所述超 帧所包含的帧的数目。 通过本实施例所列举的映射公式, 可以准确地实现传 统寻呼信息中的寻呼周期和寻呼位移到先进寻呼信息中的寻呼周期和寻呼位 移的映射。 本领域技术人员可以理解的是, 上述寻呼周期和寻呼位移的映射 公式只是本实施例的一种示例, 本发明不仅限于此, 还可以使用其他合理的 公式进行映射。 优选的, 所述第一映射模块 7021 还用于在所述先进寻呼信息中的寻呼 周期仅限于若千个可选寻呼周期时, 从所述若千个可选寻呼周期中选择小于 或等于 P g cycle"的最大的可选寻呼周期作为所述终端的以超帧为计数单 位的寻呼周期; 所述第二映射模块 7022 还用于在所述先进寻呼信息中的寻 呼位移仅限于若千个可选寻呼位移时, 从所述若千个可选寻呼位移中选择小 于或等于 p g °ffset*的最大的所述可选寻呼位移作为终端的以超帧为计数 单位的寻呼位移。 通过本实施例, 可以灵活地进行寻呼周期和寻呼位移的映 射, 并满足不同的配置需求。 优选的, 所述寻呼单元 706包括: 确定模块 7061 , 用于使用所述以超帧 述超帧号对应的超帧中用于承载寻呼广播消息的帧号; 寻呼模块 7062 , 与确 述寻呼广播消息。 优选的, 本实施例中的先进网元设备还包括: 发送单元 704 , 其中, 所 述发送单元 704包括: 发送模块 7041 , 用于将所述以超帧为单位的寻呼周期 和寻呼位移 (即先进寻呼信息)发送给所述所要寻呼的终端。 通过将先进寻 呼信息发送给所述所要寻呼的终端, 该终端可以通过该先进寻呼信息与先进 网元设备进行寻呼交互, 从而准确地实现对终端的寻呼。 优选的,所述先进网元设备为包含有第一区域和第二区域的先进控制站, 或者为仅包含有第一区域的先进控制站, 其中, 所述第一区域只能支持先进 通信协议, 所述第二区域支持传统通信协议。 优选的, 所述先进网元设备连接到传统接入网络。 通过上述限定, 使得 本发明可以适用于不同的配置场景。 优选的, 在先进网元设备接收到来自所述终端的先进寻呼参数之后, 先 进网元设备中的映射单元 702将接收到的先进寻呼参数映射成以帧为单位的 传统寻呼参数, 发送单元 704将所述传统寻呼参数发送给传统网关。 通过本 实施例, 可以实现终端到传统网关的信息传输。 优选的, 映射单元 702将接收到的先进寻呼参数映射成以帧为单位的传 统寻呼参数具体包括: 如果所述传统网关规定了传统寻呼参数的可选值, 则 所述先进控制站将以超帧为单位的先进寻呼参数映射到规定的所述可选值中 大于该先进寻呼参数的最小的可选值, 或者, 映射到规定的所述可选值中小 于该先进寻呼参数的最大的可选值。 通过本实施例, 先进网元设备可以满足 不同场景下的需求。 优选的, 所述先进网元设备在以下场景之一下将接收到的先进寻呼参数 映射成以帧为单位的传统寻呼参数: 所述终端进入闲置模式, 或者, 所述终 端进行位置更新。 优选的, 在所述先进网元设备使用所述先进寻呼信息寻呼所述所要寻呼 的终端之前, 映射单元 702将进入闲置模式的所要寻呼的终端所对应的传统 寻呼信息映射成所述先进寻呼信息; 先进网元设备中的发送单元 704将所述 先进寻呼信息发送给所述所要寻呼的终端, 以便所述终端使用所述先进寻呼 信息与所述先进网元设备进行所述寻呼过程。 优选的, 在先进网元设备中的映射单元 702将进入闲置模式的终端所对 应的传统寻呼信息映射成先进寻呼信息, 并将所述先进寻呼信息发送给所述 终端之后, 所述终端在进入所述闲置模式的过程中接收所述先进网元设备发 送的所述先进寻呼信息; 当所述终端进入所述闲置模式后, 使用所接收的所 述先进寻呼信息监听寻呼广播消息。 通过本实施例, 可以实现先进网元设备 与终端之间的交互。 优选的, 在所述终端使用所接收的所述先进寻呼信息监听寻呼广播消息 之后, 若所述终端从所述寻呼广播消息中获知被寻呼要求进行位置更新时, 则进行位置更新; 若所述终端从所述寻呼广播消息中获知被寻呼要求退出所 述闲置模式进行网络重入时, 则进行网络重入; 若所述终端从所述寻呼广播 消息中获知没有被寻呼, 则进入寻呼不可及间隔。 通过本实施例, 可以实现 不同的更新处理。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 并 且在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤, 或者 将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作 成单个集成电路模块来实现。 这样, 本发明不限制于任何特定的硬件和软件 结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
