Description

一种集群通信的寻呼方法和相关设备 本申请要求于 2011 年 09 月 02 日提交中国专利局、 申请号为 201110258791.4、发明名称为"一种集群通信的寻呼方法和相关设备"的中国 专利申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及无线通讯技术领域, 尤其涉及一种集群通信的寻呼方法和 相关设备。
背景技术 集群通信业务是指一种多个用户共享并动态使用一组无线信道的专用 通信系统, 因为集群通信可以为多个部门、 单位等集团用户提供专用指挥 调度, 所以集群通信对时延和可靠性等要求较高。
对于集群通信而言, 对于一个用户初始发起集群业务并得到通话授权 指示的时间, 称之为起呼时延( Initial PTT Latency), 如何减少集群通 信的起呼时延成为业界关注的重点。 长期演进(LTE, Long Term Evolution) 技术中引入了非连续接收 (DRX, Discontinue Reception) 功能, 能够有 效节省用户设备(UE, User Equipment ) 的耗电量, 延长待机时间。 DRX可 以分为两种, 无线资源控制协议 -空闲(RRC_IDLE, Radio Resource Control - 1 DLE )态下的 DRX和无线资源控制协议 -连接( RRC - C0匪 ECTED )态下的 DRX。 其中 RRC-IDLE态下的 DRX技术主要用于控制 UE在可能有下行寻呼信息到 达的时刻去监听物理下行控制信道 (PDCCH, Physical Downlink Control Channel ), 查看是否有属于自己的寻呼消息, 若有则进一步解码物理下行 共享信道 (PDSCH, Physical Downlink Shared Channel )获得寻呼消息的 详细内容。
LTE 的默认 DRX 周期包含如下的可选值: 320ms, 640ms, 1280ms, 2560ms...。 由于这些寻呼周期较长, 难以满足集群通信的快速建立时间要 求。 无法继续釆用 LTE 的寻呼模式来支持集群业务, 需要进一步缩短寻呼 周期。
为了节省集群通信的起呼时延以实现集群通信的快速寻呼, 存在一种 现有技术: 设计了一种新的集群寻呼信道, 集群寻呼信道(TPCH, Trunking Pag ing Channe l )通过系统消息下发集群的寻呼周期与寻呼位置, 从而对 有大量群组或者大量集群用户存在的小区, 造成空口资源开销非常显著, 导致无线资源的利用效率低下。

在本发明实施例提供的另一种集群通信的寻呼方法中, 用户设备首先 预置计算寻呼帧 SFN的关系式, 用户设备在以 N为寻呼周期的寻呼帧 SFN 上接收基站发送的组寻呼, 而 N 的设定是用户设备所在的小区广播的默认 寻呼周期 T和 nB的最小值, 故可以缩短寻呼周期, 减少集群通信的起呼时 延。 另外不需要针对不同的用户和所加入的不同的群组分别广播系统消息, 能够减少小区的空口资源开销, 提高无线资源的利用率, 由于对现有的 LTE 系统本身不需要做较大修改, 系统兼容性较强。
在本发明实施例提供的另一种集群通信的寻呼方法中, 基站向用户设 备发送寻呼周期修正参数, 该寻呼周期修正参数用于表示将用户设备所在 的小区广播的默认寻呼周期 T修正为寻呼周期 T/M,由于寻呼周期被修正缩 小了 M倍, 故可以缩短寻呼周期, 减少集群通信的起呼时延。 另外不需要 针对不同的用户和所加入的不同的群组广播系统消息, 能够减少小区的空 口资源开销, 提高无线资源的利用率, 由于对现有的 LTE 系统本身不需要 做较大修改, 系统兼容性较强。

具体实施方式 本发明实施例提供了一种集群通信的寻呼方法和相关设备, 用于缩短 集群通信的起呼时延, 减少小区的空口资源开销, 能够很好的兼容现有的 系统架构。
为使得本发明的发明目的、 特征、 优点能够更加的明显和易懂, 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, 下面所描述的实施例仅仅是本发明一部分实施例, 而 非全部实施例。 基于本发明中的实施例, 本领域的技术人员所获得的所有 其他实施例, 都属于本发明保护的范围。
对于 RRC-IDLE态下的 DRX, 其寻呼帧 (PF, Paging Frame )可以由如 下公式(1 )计算得出:
SFN mod T= (T div N) * (UE—ID mod N) ( 1 ) 其中, SFN是系统帧号, T是不连续寻呼周期, Ν是一个不连续寻呼周 期内的寻呼帧的数量, UE _ I D是用户设备的标识符。
寻呼帧内子帧 (Ρ0, Paging Occasion)可以由如下公式 (2)计算得 出:
i-s = floor ( UE-ID/N ) mod Ns
(2)
其中, i-s为寻呼帧内子帧的值, Ns为一个寻呼帧内寻呼子帧的数目。 由上面两个公式可以分别计算出 PF和 P0 ,所用到的参数具体说明如下: nB: 4T, 2T, Τ, T/2, T/4, T/8, T/16, T/32 ...
N: min (T, nB)
Ns: max(l,nB/T)
UE—ID: IMSI mod 1024
IMSI 为国际移动用户识另1 J码 ( International Mobile Subscriber Identification Number )。
T为不连续寻呼周期, 如果上层指派了 DRX周期, 且 UE所在小区也广 播了默认 DRX周期, 则 T取两者中的最小值为不连续寻呼周期, 如果上层 未指派 DRX周期, 则 T取小区默认的 DRX周期。
上层指派的 DRX周期为 UE在附着( ATTACH )过程的附着请求消息中携 带、 由 UE传输给 MME, 基站 (eNode B)并不知道该上层指派的 DRX周期。 当 MME下发寻呼消息时, 会携带该数值通知给 eNode B。 同时 UE系统广播 消息可以得到 RRC配置的默认 DRX周期。 nB值也是由 UE从系统消息读取到。 获得这些信息后 UE与 eNode B均可以按照公式( 1 )和公式( 1 )计算出 PF 与 P0的出现位置, 则 eNode B在这个位置下发寻呼消息, UE在相同位置接 收寻呼消息。现有的 LTE的默认 DRX周期包含如下的可选值: 320ms, 640ms, 1280ms, 2560ms...。 由于这些寻呼周期较长, 难以满足集群通信的快速建 立时间要求。 无法继续釆用 LTE 的寻呼模式来支持集群业务, 需要进一步 缩短寻呼周期。
为了节省集群通信的起呼时延以实现集群通信的快速寻呼, 设计了一 种新的集群寻呼信道, 将集群分为单呼和组呼, 从集群寻呼控制信道
( TPCCH , Trunk ing Pag ing Control Channe l )映射到集群寻呼信道 ( TPCH, Trunking Pag ing Channe l ), 最后映射到 PDSCH, 集群寻呼消息由 TPCCH下 发。 TPCCH通过系统消息下发集群的寻呼周期与寻呼位置,但是对于不同的 用户和所加入的不同的群组, 他们的寻呼周期与寻呼位置一般都是不相同 的, 因此需要下发的系统消息也是不相同的, 所以 TPCCH需要针对不同用 户和所加入的不同群组分别广播不同的系统信息, 因而对有大量群组或者 大量集群用户存在的小区来说会造成空口资源开销非常显著, 导致无线资 源的利用效率低下。 另外, 该设计新的集群寻呼信道的方案对现有的 LTE 系统本身修改较大, 增加了新的逻辑信道, 降低了系统兼容性。
因此, 为了解决上述技术问题, 本发明提供了如下的技术方案。
本发明实施例提供的基于用户设备侧实现的一种集群通信的寻呼方 法, 如图 1所示, 包括:
101、 用户设备向移动管理实体发送信息更新请求。
在本发明实施例中, 用户设备首先向移动管理实体( MME, Mobility Management Entity )发送信息更新请求, 用于更新用户设备的集群信息。 在实际应用中, 存在多种实现方式。 例如, 信息更新请求具体包括附着请 求信息, 当用户设备开机时, 用户设备主动的向移动管理实体发送附着请 求( Attach Request )信息。 信息更新请求具体包括跟踪区更新请求信息, 当跟踪区更新时, 用户设备向移动管理实体发送跟踪区更新请求信息。
用户设备首先向移动管理实体发送信息更新请求, 移动管理实体接收 到该信息更新请求之后转发用户设备向集群服务器请求集群信息的消息, 集群服务器向该移动管理实体反馈参数配置信息。
在本发明实施例中, 集群服务器为用户设备设定群组指定非连续接收 周期( Group specific DRX ) ,在本发明实施例中由集群服务器来为用户设定 群组指定非连续接收周期, 一种优选的实现方式是, 集群服务器为用户设 备设定的群组指定非连续接收周 10Π21 期为 ms, i为自然数。 即, 集群服 务器设定的群组指定非连续接收周期为 10ms、20ms、 40ms、 80ms、 160ms...。
请参阅表 1 为本发明实施例中集群服务器设定的群组指定非连续接收 周期的表, 表 1用一个字节的四个比特位第 8位、 第 7位、 第 6位、 第 5 位来表示集群服务器设定的群组指定非连续接收周期。
表 1为群组指定 DRX周期表
Figure imgf000014_0001
集群服务器接收到该附着请求信息之后向移动管理实体发送参数配置 信息, 其中, 集群服务器发送的参数配置信息包括用户设备加入的群组的 群组标识(G-ID, Group Identifier )和集群服务器预置的群组指定非连续接 收周期。 一种优选的实现方式是, 集群服务器预置的群组指定非连续接收 周期小于用户设备所在的小区广播的默认寻呼周期。 用户设备所在的小区 广播的默认寻呼周期一般为 320ms、 640ms, 1280ms, 2560ms...„ 例如, 用户设备所在的小区广播的默认寻呼周期为 320ms, 集群服务器为用户设 备预置的群组指定非连续接收周期可以为 10ms或 20ms等, 则该群组指定 非连续接收周期小于用户设备所在的小区广播的默认寻呼周期。
102、 用户设备接收请求响应信息。
移动管理实体从集群服务器接收到参数配置信息之后, 移动管理实体 会向用户设备反馈请求响应信息, 该请求响应信息包括用户设备加入的群 组的群组标识和集群服务器预置的群组指定非连续接收周期。 在不同的应 用场景下, 请求响应信息具体可以是不同的信息。 例如, 当用户设备开机 时, 移动管理实体向用户设备反馈的是附着响应( Attach Accept )信息。 当 跟踪区更新时, 移动管理实体向用户设备反馈的是跟踪区更新接受信息。
其中, 移动管理实体在接收到集群服务器下发的参数配置信息之后, 移动管理实体向用户设备发送请求响应信息, 在请求响应信息内会包括用 户设备加入的群组的 G-ID和集群服务器预置的群组指定非连续接收周期, 则用户设备通过接收该请求响应信息会得到该用户设备加入的群组的 G-ID 和集群服务器预置的群组指定非连续接收周期。
需要说明的是, 在本发明实施例中移动管理实体向用户设备发送请求 响应信息和现有的请求响应信息相比, 不同之处在于本发明实施例中的请 求响应信息比现有的请求响应信息增加了集群服务器预置的群组指定非连 续接收周期。 例如表 2所示:
表 2为请求响应信息内容

其中, 信息元素为 Information Element , 类型 /引用参考表示 Type/Reference, 出现情况表示 Presence ( M代表必选项, 0代表可选项 ), 格式表示 Format ( V、 TLV分别是格式类型的一种), 长度表示 Length ( 1/2 代表使用了半个字节)。 协议鉴别为 Protocol discriminator, 安全头类型为 Security header type , 等同公共陆地移动网络为 Equivalent PLMNs , 公共陆 地移动网络表为 PLMN list。
103、 用户设备向移动管理实体发送信息更新完成消息。
用户设备接收到该用户设备加入的群组的 G-ID和集群服务器预置的群 组指定非连续接收周期之后, 用户设备向移动管理实体反馈信息更新完成 消息, 用以表示该用户设备接收到了请求响应信息。 在不同的应用场景下, 信息更新完成消息具体可以是不同的信息。 例如, 当用户设备开机时, 用 户设备向移动管理实体反馈的是附着完成( Attach Complete )信息。 当跟踪 区更新时, 用户设备向移动管理实体反馈的是跟踪区更新完成消息。
104、 当用户设备发起集群业务之后, 用户设备将该用户设备所在的小 区广播的默认寻呼周期与群组标识对应的群组指定非连续接收周期中的最 小值作为寻呼周期, 按照该寻呼周期接收基站发送的组寻呼。
在本发明实施例中, 当用户设备发起集群业务时, 移动管理实体会向 基站下发组寻呼信息, 该组寻呼信息包括: 该用户设备加入的群组的群组 标识和所述群组标识对应的所述群组指定非连续接收周期。在前述操作 102 中, 移动管理实体会向用户设备发送请求响应信息, 用户设备可以获取到 该用户设备加入的群组的群组标识和集群服务器预置的群组指定非连续接 收周期, 但是该请求响应信息对基站而言是透传的, 基站不会得到该请求 响应信息。 当用户设备发起集群业务时, 移动管理实体会主动向基站下发 组寻呼信息, 用以告诉基站该用户设备加入的群组的群组标识和集群服务 器预置的群组指定非连续接收周期。 基站接收移动管理实体发送的组寻呼 信息之后, 从用户设备所在的小区广播的默认寻呼周期与群组标识对应的 群组指定非连续接收周期中选择最小值作为寻呼周期, 并按照该寻呼周期 向用户设备发送组寻呼。 在本发明实施例中, 基站之所以从用户设备所在 的小区广播的默认寻呼周期与群组标识对应的群组指定非连续接收周期中 选择最小值作为寻呼周期是为了更好的兼容原有系统, 因为在原有系统中 会判断小区广播的默认 DRX周期和上层指派的 DRX周期然后取最小值, 本发明实施例中, 基站侧和用户设备侧使用同样的判断机制, 能够更好的 融合原有系统。
在本发明实施例提供的一种集群通信的寻呼方法中, 由集群服务器来 为用户设备设定群组指定非连续接收周期, 在集群服务器向移动管理实体 下发群组指定非连续接收周期之后, 移动管理实体会通过请求响应信息向 用户设备告知群组指定非连续接收周期, 由于用户设备会选择将用户设备 所在的小区广播的默认寻呼周期与群组标识对应的群组指定非连续接收周 期中的最小值作为寻呼周期, 按照该寻呼周期接收基站发送的组寻呼可以 减少用户设备的起呼时延。 另外不需要针对不同的用户和所加入的不同的 群组分别广播系统消息, 能够减少小区的空口资源开销, 提高无线资源的 利用率, 由于对现有的 LTE系统本身不需要做较大修改, 系统兼容性较强。
本发明实施例提供的基于移动管理实体侧实现的一种集群通信的寻呼 方法, 如图 1所示, 包括:
201、 移动管理实体接收用户设备发送的信息更新请求。 在本发明实施例中, 移动管理实体接收到用户设备发送的信息更新请 求存在多种实现方式。 例如, 信息更新请求具体包括附着请求信息, 当用 户设备开机时, 移动管理实体接收用户设备发送的附着请求信息。 信息更 新请求具体包括跟踪区更新请求信息, 当跟踪区更新时, 移动管理实体接 收用户设备发送的跟踪区更新请求信息。
202、 移动管理实体从集群服务器获取用户设备加入的群组的群组标识 和集群服务器预置的群组指定非连续接收周期。
在移动管理实体接收用户设备发送的信息更新请求之后, 移动管理实 体从集群服务器获取所述用户设备加入的群组的群组标识和集群服务器预 置的群组指定非连续接收周期。 一种可选的实现方式是, 移动管理实体向 集群服务器请求该用户设备的集群信息, 集群服务器向该移动管理实体反 馈参数配置信息。 移动管理实体接收集群服务器发送的参数配置信息。 其 中, 参数配置信息包括用户设备加入的群组的群组标识和集群服务器预置 的群组指定非连续接收周期。
在本发明实施例中, 集群服务器为用户设备设定群组指定非连续接收 周期, 在本发明实施例中由集群服务器来为用户设定群组指定非连续接收 周期, 而不再像现有技术中由用户设备来上报非连续接收周期。 一种优选 的实现方式是,集群服务器为用户设备设定的群组指定非连续接 10Π21 收 周期为 ms, i为自然数。 即, 集群服务器设定的群组指定非连续接收周期 为 10ms、 20ms ^ 40ms ^ 80ms ^ 160ms...。
集群服务器接收到集群信息之后向移动管理实体发送参数配置信息, 其中, 集群服务器发送的参数配置信息包括用户设备加入的群组的群组标 识和集群服务器预置的群组指定非连续接收周期。 一种优选的实现方式是, 集群服务器预置的群组指定非连续接收周期小于用户设备所在的小区广播 的默认寻呼周期。 用户设备所在的小区广播的默认寻呼周期一般为 320ms、 640ms, 1280ms , 2560ms...。 例如, 用户设备所在的小区广播的默认寻呼 周期为 320ms, 集群服务器为用户设备预置的群组指定非连续接收周期可 以为 10ms或 20ms等, 则该群组指定非连续接收周期小于用户设备所在的 小区广播的默认寻呼周期。
203、 移动管理实体向用户设备发送请求响应信息。
其中, 请求响应信息包括用户设备加入的群组的群组标识和集群服务 器预置的群组指定非连续接收周期。 在不同的应用场景下, 请求响应信息 具体可以是不同的信息。 例如, 当用户设备开机时, 用户设备向移动管理 实体发送附着请求信息, 移动管理实体向用户设备反馈的是附着响应信息。 当跟踪区更新时, 用户设备向移动管理实体发送跟踪区更新请求信息, 移 动管理实体向用户设备反馈的是跟踪区更新接受信息。
移动管理实体在接收到集群服务器下发的参数配置信息之后, 移动管 理实体向用户设备发送请求响应信息, 在请求响应信息内会包括用户设备 加入的群组的 G-ID和集群服务器预置的群组指定非连续接收周期, 则用户 设备通过接收该请求响应信息会得到该用户设备加入的群组的 G-ID和集群 服务器预置的群组指定非连续接收周期。
204、 当用户设备发起集群业务时, 移动管理实体向基站发送组寻呼信 息。
其中, 组寻呼信息包括用户设备加入的群组的群组标识和集群服务器 预置的群组指定非连续接收周期, 以使基站从用户设备所在的小区广播的 默认寻呼周期与群组标识对应的所述群组指定非连续接收周期中选择最小 值作为寻呼周期, 并按照该寻呼周期向用户设备发送组寻呼。
在本发明实施例提供的一种集群通信的寻呼方法中, 由集群服务器来 为用户设备设定群组指定非连续接收周期, 在集群服务器向移动管理实体 下发群组指定非连续接收周期之后, 移动管理实体会通过请求响应信息向 用户设备告知群组指定非连续接收周期, 由于用户设备会选择将用户设备 所在的小区广播的默认寻呼周期与群组标识对应的群组指定非连续接收周 期中的最小值作为寻呼周期, 按照该寻呼周期接收基站发送的组寻呼可以 减少用户设备的起呼时延。 另外不需要针对不同的用户和所加入的不同的 群组分别广播系统消息, 能够减少小区的空口资源开销, 提高无线资源的 利用率, 由于对现有的 LTE系统本身不需要做较大修改, 系统兼容性较强。
下面介绍本发明实施例提供的基于集群服务器侧实现的一种集群通信 的寻呼方法, 如图 3所示, 包括:
301、 集群服务器为用户设备生成群组指定非连续接收周期。
在本发明实施例中, 由集群服务器主动的为用户设备生成群组指定非 连续接收周期。 一种优选的实现方式是, 集群服务器为用户设备设定的群 组指定非连续接收周期 10Π21 为 ms, i为自然数。 即, 集群服务器设定 的群组指定非连续接收周期为 10ms、 20ms, 40ms, 80ms, 160ms...。 与现 有技术不同的是由用户设备上报寻呼周期, 而本发明实施例中, 集群服务 器主动的生成群组指定非连续接收周期。 一种优选的实现方式是, 集群服 务器预置的群组指定非连续接收周期小于用户设备所在的小区广播的默认 寻呼周期。用户设备所在的小区广播的默认寻呼周期一般为 320ms、 640ms, 1280ms、 2560ms...。 例如, 用户设备所在的小区广播的默认寻呼周期为 320ms , 集群服务器为用户设备预置的群组指定非连续接收周期可以为 10ms或 20ms等, 则该群组指定非连续接收周期小于用户设备所在的小区 广播的默认寻呼周期。
302、 集群服务器接收移动管理实体转发的用户设备向集群服务器请求 集群信息的消息。
在本发明实施例中, 集群服务器从移动管理实体处接收到用户设备请 求集群信息的消息, 例如, 当用户设备开机时, 用户设备向移动管理实体 请求集群信息, 移动管理实体会将该请求集群信息的消息转发给集群服务 器。 当跟踪区更新时, 用户设备向移动管理实体请求集群信息, 移动管理 实体会将该请求集群信息的消息转发给集群服务器。
303、 集群服务器向移动管理实体发送参数配置信息, 其中, 参数配置 信息包括用户设备加入的群组的群组标识和集群服务器预置的群组指定非 连续接收周期。
集群服务器向移动管理实体发送参数配置信息, 一种优选的实现方式 是, 该参数配置信息中集群服务器预置的群组指定非连续接收周期小于用 户设备所在的小区广播的默认寻呼周期。
下面以一个实际的应用例来介绍如图 1、 图 2、 图 3所示的本发明实施 例中的集群通信的寻呼方法。
集群服务器向移动管理实体下发的 G-ID作为组呼标识, G-ID是由两 个字符串表示的组标识。修改 UEIdentitylndexValue参数为 G-ID(群组标识 ) 用于计算 PF。
群组指定非连续接收周期为
PagingDRX :: = ENUMERATED
{vl ,v2,v4,v8,vl6,v32,v64,vl28,v256,... } ,
对于现有的默认寻呼周期为 PagingDRX: :=ENUMERATED { v32,v64,vl28,v256,...}„ 相对于现有的 PagingDRX增加四个寻呼周期 vl , v2, v4, v8, vl6为 本发明实施例中的群组指定非连续接收周期, vl , v2, v4, v8, vl6分别代 表 10ms, 20ms, 40ms, 80ms, 160ms。
假定小区广播的默认寻呼周期 T为 16 (即 160ms ), 集群服务器指派的 群组指定非连续接收周期为 4 (即 40ms ),即对应 PagingDRX为 v4的数值; nB为 T/4; UE ID = G-ID mod 1024, 令其为 5。
则 T = min(16,4) = 4;
N = min(T,nB)=T/4 = 1 ;
Ns = max(l,nB/T) = 1。
PF的计算如下:
SFN mod T = (T div N) * (UE ID mod N) = 4*0 = 0;
所以 PF的寻呼位置为: 0, 0+4, 0+4+4, ...。 在子帧 0、 子帧 4、 子帧 8...上可以接收基站的组寻呼, 即每隔 4个帧会有一个子帧的位置都可以作 为寻呼位置。
对于非集群 UE, 其寻呼周期为小区默认寻呼周期 T = 16, 则相应 PF 为:
SFN mod T = (T div N)*(UE— ID mod N) = 0 ,
即非集群的 PF的寻呼位置为: 0, 0+16, 0+16+16, …。
请参阅图 4,为上述应用例中集群 UE和非集群 UE的寻呼周期示意图。 按照本发明实施例中的方法, 集群通信中 UE的寻呼周期为 40ms, 非集群 业务的 UE的寻呼周期为 160ms, 集群通信中 UE的寻呼周期远小于非集群 业务的 UE的寻呼周期。
以上实施例介绍了一种集群通信的寻呼方法, 接下来介绍本发明实施 例提供的另一种集群通信的寻呼方法。
本发明实施例提供的基于用户设备侧实现的一种集群通信的寻呼方 法, 请参阅图 5所示, 包括:
501、 用户设备预置计算寻呼帧 SFN的关系式:
SFN mod N = UE ID mod N。
其中, N为集群寻呼周期, N = min(T,nB) , UE ID = G-ID mod 1024 , G-ID是用户设备加入的群组的群组标识, T为所述用户设备所在的小区广 播的默认寻呼周期, nB为基站广播的寻呼密度相关参数。
502、当用户设备发起集群业务之后,用户设备接收基站发送的组寻呼。 该组寻呼所使用的寻呼帧 SFN满足如下关系式:
SFN mod N = UE ID mod N,
在本发明实施例中, 一种可选的实现方式是, nB满足如下关系: 若 nB大于 T/M,在进行集群寻呼周期计算时,用户设备将 N = min(T,nB) 中 nB的值替换为 T/M。 M为用户设备和基站中都预置的寻呼周期修正参数。
若 nB 小于 10ms , 在进行集群寻呼周期计算时, 用户设备将 N = min(T,nB)中 nB的值替换为 10ms。
需要说明的是, nB 值由基站设定, T1 可以为 T/4、 Τ/8、 Τ/16、 Τ/32 中的一个。 另外, 寻呼周期修正参数 Μ是直接预置在基站和用户设备中。
在实际应用中, PCCH-Conf ig 的配置协议格式如下:
PCCH-Conf ig :: = SEQUENCE {
defaul tPagingCycle ENUMERATED {
rf 32, rf64, rfl28, rf256} ,
nB ENUMERATED {
f ourT, twoT, oneT, ha lfT, quar terT, oneEighthT,
oneSixteenthT, oneThir tySecondT}
}
在本发明实施例提供的集群通信的寻呼方法中, 用户设备首先预置计 算寻呼帧 SFN的关系式, 用户设备在以 N为寻呼周期的寻呼帧 SFN上接收 基站发送的组寻呼, 而 N 的设定是用户设备所在的小区广播的默认寻呼周 期 T和 nB的最小值, 故可以缩短寻呼周期, 减少集群通信的起呼时延。 另 外不需要针对不同的用户和所加入的不同的群组分别广播系统消息, 能够 减少小区的空口资源开销, 提高无线资源的利用率, 由于对现有的 LTE 系 统本身不需要做较大修改, 系统兼容性较强。
下面给出一个具体的应用例进行说明:
假设用户设备所在的小区广播的默认寻呼周期 T = 32 , UE_ ID = G-ID mod 1024 , 令其为 5。 nB = T/8则有 N = min (T, nB) = 4。
集群 UE的 PF为: SFN mod N = UE—ID mod N = 1。
所以 PF的寻呼位置为: 1 , 1+4, 1+4+4, ...。 在子帧 0、 子帧 4、 子帧 8...上可以接收基站的组寻呼。 即每隔 4个帧会有一个子帧的位置都可以作 为寻呼位置。
对于非集群 UE, 其寻呼周期为小区默认寻呼周期 T = 32, 则相应 PF 为:
SFN mod T = (T div N)*(UE— ID mod N) = 8 ,
即非集群的 PF的寻呼位置为: 8, 8+16, 8+16+16, …。
可以计算出非集群 UE位于寻呼帧的第 8号子帧、 第 16号子帧、 . . ., 寻呼周期为 320ms。
请参阅图 6所示,为上述应用例中集群 UE和非集群 UE的寻呼周期示 意图。 按照本发明实施例中的方法, 集群通信中 UE的寻呼周期为 40ms, 子帧 1和子帧 5为集群通信中 UE的寻呼位置。非集群业务的 UE的寻呼周 期为 320ms, 子帧 8为非集群业务的 UE的寻呼位置。 集群通信中 UE的寻 呼周期远小于非集群业务的 UE的寻呼周期。
本发明实施例提供的基于基站侧实现的一种集群通信的寻呼方法, 如 图 7所示, 包括:
701、基站预置计算寻呼帧 SFN的关系式: SFN mod N = UE—ID mod N。 其中, N为集群寻呼周期, N = min(T,nB) , UE ID = G-ID mod 1024 , G-ID是用户设备加入的群组的群组标识, T为用户设备所在小区广播的默 认寻呼周期, nB为基站广播的寻呼密度相关参数。
702、基站向用户设备发送组寻呼。该组寻呼中所使用的寻呼帧 SFN满 足关系式: SFN mod N = UE ID mod N。
在本发明实施例中, 一种可选的实现方式是, nB满足如下关系: 若 nB大于 T/M,在进行集群寻呼周期计算时,用户设备将 N = min(T,nB) 中 nB的值替换为 T/M。 M为用户设备和基站中都预置的寻呼周期修正参数。
若 nB 小于 10ms , 在进行集群寻呼周期计算时, 用户设备将 N = min(T,nB)中 nB的值替换为 10ms。
需要说明的是, nB 值由基站设定, T1 可以为 T/4、 Τ/8、 Τ/16、 Τ/32 中的一个。 另外, 寻呼周期修正参数 Μ是直接预置在基站和用户设备中。
在本发明实施例提供的集群通信的寻呼方法中, 基站首先预置计算寻 呼帧 SFN的关系式, 基站在以 N为寻呼周期的寻呼帧上向用户设备发送组 寻呼, 而 N的设定是用户设备所在的小区广播的默认寻呼周期 T和 nB的最 小值, 故可以缩短寻呼周期, 减少集群通信的起呼时延。 另外不需要针对 不同的用户和所加入的不同的群组分别广播系统消息, 能够减少小区的空 口资源开销, 提高无线资源的利用率, 由于对现有的 LTE 系统本身不需要 做较大修改, 系统兼容性较强。
接下来介绍本发明实施例提供的另一种集群通信的寻呼方法。 如图 8 所示, 本发明实施例提供的基于基站侧实现的集群通信的寻呼方法包括:
801、 基站向用户设备发送寻呼周期修正参数。
其中, 寻呼周期修正参数用于表示将用户设备所在的小区广播的默认 寻呼周期 T修正为寻呼周期 T/M, M为非零的自然数。
在本发明实施例中,基站按照用户设备所在小区广播的默认寻呼周期 T 将 T分成 M份, 这样相当于把集群寻呼的寻呼周期缩短为 T/M, M为非零 的自然数。集群通信中的基站向用户设备发送该参数 M, 新为集群引入一个 称为 M的参数。
在实际应用中, 基站向用户设备发送寻呼周期修正参数具体可以为, 基站通过系统消息块类型 2 ( SIB 2 , Sys tem Informa t ion Block 2 ) 中携 带寻呼周期修正参数 M、 nB、 T向用户设备广播。 当然还可以存在其它向用 户设备发送寻呼周期修正参数的方法, 例如, 基站可以通过一个单独的信 令直接向用户设备发送寻呼周期修正参数, 基站也可以借助系统中其它的 信令向用户设备发送寻呼周期修正参数等, 此处不作限定。
802、 基站向用户设备发送组寻呼。
基站向用户设备发送组寻呼所使用的寻呼帧 SFN满足如下关系式: SFN mod (T/M) = ((T/M) div N)*(UE— ID mod N),
其中 , 寻呼周期内寻呼帧的数目 Ν = min(T/M,nB) , T为用户设备所在 的小区广播的默认寻呼周期, UE— ID = G-ID mod 1024 , G-ID是用户设备加 入的群组的群组标识, nB为 4T, 2T, Τ, T/2, T/4, T/8, T/16, T/32中的一个值。
在本发明实施例提供的一种集群通信的寻呼方法中, 基站向用户设备 发送寻呼周期修正参数, 该寻呼周期修正参数用于表示将用户设备所在的 小区广播的默认寻呼周期 T修正为寻呼周期 T/M,由于寻呼周期被修正缩小 了 M倍, 故可以缩短寻呼周期, 减少集群通信的起呼时延。 另外不需要针 对不同的用户和所加入的不同的群组分别广播系统消息, 能够减少小区的 空口资源开销, 提高无线资源的利用率, 由于对现有的 LTE 系统本身不需 要做较大修改, 系统兼容性较强。
下面给出一个具体的应用例进行说明:
假设用户设备所在的小区广播的默认寻呼周期 T = 32 , UE_ ID = G-ID mod 1024 , 令其为 5。 nB = T/4 , 则有 N = min (T, nB) = 4。 假设基站选取的寻 呼周期修正参数 M=8 , 则 T/M= 4。
集群 UE的 PF为:
SFN mod (T/M) = ((T/M) div N)*(UE— ID mod N) = 1。
所以 PF的寻呼位置为: 1 , 1+4, 1+4+4, ...。 在子帧 0、 子帧 4、 子帧 8...上可以接收基站的组寻呼。 即每隔 4个帧会有一个子帧的位置都可以作 为寻呼位置。
对于非集群 UE, 其寻呼周期为小区默认寻呼周期 T = 32, 则相应 PF 为:
SFN mod T = (T div N)*(UE— ID mod N) ,
即非集群的 PF的寻呼位置为: 20, 20+32, 20+32+32, …。
可以计算出非集群 UE首次出现在寻呼帧的第 20号子帧上, 寻呼周期 为 320ms。
请参阅图 9所示,为上述应用例中集群 UE和非集群 UE的寻呼周期示 意图。 按照本发明实施例中的方法, 集群通信中 UE的寻呼周期为 40ms, 子帧 1和子帧 5为集群通信中 UE的寻呼位置。非集群业务的 UE的寻呼周 期为 320ms, 子帧 20为非集群业务的 UE的寻呼位置。 集群通信中 UE的 寻呼周期远小于非集群业务的 UE的寻呼周期。
接下来介绍本发明实施例提供的基于用户设备侧实现的一种集群通信 的寻呼方法, 如图 10所示, 包括:
1001、 用户设备接收基站发送的寻呼周期修正参数。
其中, 寻呼周期修正参数用于表示将用户设备所在的小区广播的默认 寻呼周期 T修正为寻呼周期 T/M, M为非零的自然数。
在本发明实施例中, 用户设备接收基站发送的寻呼周期修正参数。 用 户设备接收到该寻呼周期修正参数之后, 用户设备按照用户设备所在小区 广播的默认寻呼周期 T将 T分成 M份,这样相当于把集群寻呼的寻呼周期 缩短为 T/M, M为非零的自然数。集群通信中用户设备获取到该参数 M, 新 为集群引入一个称为 M的参数。
在实际应用中, 用户设备接收基站发送的寻呼周期修正参数具体可以 为, 用户设备接收基站广播的系统消息块类型 2 , 该系统消息块类型 1中携 带寻呼周期修正参数 M、 nB、 T。 当然用户设备还可以存在其它接收寻呼周 期修正参数的方法, 例如, 用户设备可以通过基站使用的一个单独的信令 接收到寻呼周期修正参数, 用户设备还可以通过基站借助的系统中其它的 信令接收到寻呼周期修正参数等, 此处不作限定。
1002、 用户设备接收基站发送的组寻呼。
用户设备接收基站发送的组寻呼所使用的寻呼帧 SFN 满足如下关系 式:
SFN mod (T/M) = ((T/M) div N)*(UE— ID mod N),
其中 , 寻呼周期内寻呼帧的数目 Ν = min(T/M,nB) , T为用户设备所在 的小区广播的默认寻呼周期, UE— ID = G-ID mod 1024 , G-ID是用户设备加 入的群组的群组标识, nB为 4T, 2T, Τ, T/2, T/4, T/8, T/16, T/32中的一个值。
在本发明实施例提供的一种集群通信的寻呼方法中, 用户设备接收基 站发送寻呼周期修正参数, 该寻呼周期修正参数用于表示将用户设备所在 的小区广播的默认寻呼周期 T修正为寻呼周期 T/M,由于寻呼周期被修正缩 小了 M倍, 故可以缩短寻呼周期, 减少集群通信的起呼时延。 另外不需要 针对不同的用户和所加入的不同的群组分别广播系统消息, 能够减少小区 的空口资源开销, 提高无线资源的利用率, 由于对现有的 LTE 系统本身不 需要做较大修改, 系统兼容性较强。
以上实施例介绍了几种不同的集群通信的寻呼方法, 接下来分别介绍 使用这些方法的装置设备。
