Description

寻呼终端的雄及装置
本申请要求于 2010年 5月 18日提交中国专利局、 申请号为 201010176812. 3、发明 名称为 "寻呼终端的方法及装置"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 本发明涉及无线通信技术领域, 尤其涉及一种寻呼终端的方法及装置。 背景技术 在采用 OFDMA ( Orthogonal Frequency Division Multiplexing, 正交频分复用) 技术的移动通信系统中, 每一个用户终端在接入系统后, 进入 Active (激活)状态, 和 网络进行各种业务数据的发送和接收; 当用户终端一段时间没有业务数据需要发送和接 收, 满足网络侧设定的进入 Idle (空闲)状态的条件时, 网络或者用户就会主动发起进 入 Idle的流程, 释放用户终端当前使用的网络资源, 进入 Idle空闲状态。
在空闲状态下, 用户终端不再接收网络的各种指配消息, 不会和网络发生任何控制 信令或者业务数据的传送交互过程。 在空闲状态下, 用户终端会定期关注网络下发的广 播信息和是否有来自网络对自己的寻呼信令。 更具体的说, 每个用户终端在进入空闲状 态时, 网络会分配给用户终端一套寻呼参数, 包括寻呼周期和相应的寻呼偏移。 用户终 端就会周期性地在每个寻呼周期的该寻呼偏移去接听网络下发的广播消息。
当网络侧有数据需要发送给用户终端时, 比如来自远方的一个 VoIP 电话呼叫当前 用户终端, 网络就需要在用户终端监听的寻呼周期的对应寻呼偏移下发对该用户终端的 寻呼消息, 该寻呼消息主要包含用户终端的完整标识信息, 比如 48比特的 MAC Address (MAC地址)。 当用户终端监听到针对自己的寻呼消息, 就会重新接入系统, 返回正常的 Active激活状态。如果网络在一段时间内没有收到用户终端的响应(即用户终端重新发 起接入网络的请求), 网络就会在下一个寻呼周期的对应寻呼偏移位置继续下发对当前 用户终端的寻呼消息,直到收到当前用户终端的寻呼响应或者发送针对该用户终端的寻 呼消息达到系统设定的最大消息发送次数。
当网络需要同时寻呼多个用户终端时, 一般来说, 会针对每个用户终端单独发送寻 呼消息; 当有多个欲寻呼用户终端的寻呼参数完全相同时, 即这多个用户终端的寻呼周 期和寻呼偏移都相同时, 网络可以在一条寻呼消息中同时包含这几个用户终端的用户标 识, 进行多个用户终端的寻呼。 当一条包含多个用户终端的寻呼消息长度过大时, 网络 可以将该寻呼消息拆分为几条较短的寻呼消息分别下发。
本发明人在研究过程中发现, 现有技术通过携带完整的用户标识来寻呼用户终端, 由于空口资源的限制, 寻呼的容量是有限的, 不能支持大量用户终端的同时寻呼需求。 发明内容
本发明实施例提供一种寻呼终端的方法及装置, 以支持对大容量用户终端进行快速 寻呼, 满足网络更高的通信需求。
为此, 本发明实施例采用如下技术方案:
一种寻呼终端的方法, 包括:
为预先分配的用户组配置寻呼参数, 指示用户组中的用户终端进入空闲状态; 按照所述寻呼参数向所述用户组发起分组寻呼唤醒, 并与所述用户组中被唤醒的用 户终端进行数据传输。
一种寻呼终端的装置, 包括:
空闲状态设置单元, 用于为预先分配的用户组配置寻呼参数, 并指示用户组中的用 户终端进入空闲状态;
分组寻呼单元, 用于按照所述寻呼参数向用户组发起分组寻呼唤醒;
数据传输单元, 用于与所述用户组中被唤醒的用户终端进行数据传输。
可见, 本发明实施例在缺省时设置各个用户组的用户终端均处于空闲状态, 并根据 寻呼参数, 对各用户组分别进行寻呼唤醒, 从而实现与唤醒的用户终端进行业务数据的 传输。 由于用户终端缺省处于空闲状态, 且对各用户组的用户终端是轮流寻呼, 从而提 高了系统资源的利用效率, 可支持为更大量用户终端提供服务, 同时也降低了用户终端 的处理负荷和能耗, 能够满足未来网络更高的通信需求。 附图说明 图 1为本发明实施例寻呼终端的方法流程图;
图 2为本发明实施例携带组索引 +用户标识的寻呼消息示意图;
图 3为本发明实施例携带组索引的寻呼消息示意图;
图 4为本发明实施例用户终端 i与基站交互流程图;
图 5为本发明实施例寻呼终端的通信装置示意图。 具体实肺式 本发明实施例提供一种寻呼终端的方法及装置,该方法或装置可以满足低速率用户 终端的通信需求, 并且在不修改已有移动通信系统的信道结构等物理层技术的前提下, 可以降低系统的开销。
参见图 1, 为本发明实施例提供的寻呼终端的方法流程图, 包括以下步骤:
S101 :为预先分配的用户组分配寻呼参数,指示用户组中的用户终端进入空闲状态; S102: 按照寻呼参数向用户组发起分组寻呼唤醒, 并与用户组中被唤醒的用户终端 进行数据传输。
其中, 按照寻呼参数发起分组寻呼唤醒至少包括以下两种实现方式: 在把用户终端 按照不同寻呼周期进行分组的情况下, 当每个寻呼周期的寻呼偏移时间到时, 系统就会 向属于该用户组的所有用户终端发送寻呼唤醒消息; 在把用户终端按照同一寻呼周期不 同寻呼偏移进行分组的情况下, 当寻呼周期的每个寻呼偏移时间到时, 系统就会向属于 该用户组的所有用户终端发送寻呼唤醒消息。
可见, 本发明实施例在缺省时设置各个用户组的用户终端均处于空闲状态, 并根据 寻呼参数, 对各个用户组分别进行寻呼唤醒, 从而实现与唤醒的用户终端进行业务数据 的传输。 由于用户终端缺省处于空闲状态, 且对各用户组的用户终端是轮流寻呼, 从而 提高了系统资源的利用效率, 可支持为更大量用户终端提供服务, 同时也降低了用户终 端的处理负荷和能耗。
需要说明的是,本发明实施例适用于各种低速率通信的系统, 除了 M2M (Machine to
Machine, 机器到机器) 系统外, 还包括人与人通信的系统以及人与机器通信的系统, 只要这个系统中的用户终端对速率要求不是特别高即可。
下面以一个具体实例对方案进行详细介绍。
1 ) 基站将接入的终端分成不同的用户组, 每个用户组包括至少一个用户终端。 基站根据用户终端接入系统的时间顺序、 无线环境信息、 用户终端的能力信息或用 户终端的业务 QoS需求等, 或者根据基站系统的自身负荷情况, 将用户终端灵活进行分 组。 分组的大小和数目根据系统负荷、 当前接入用户数目、 用户终端业务吞吐量需求和 系统准备支持的最大用户终端容量规格来灵活确定。 一般来说, 无线环境相似或者相近 的用户终端分在一组, 业务需求相同或者相似的用户终端分在一组, 根据进入系统的时 间顺序进行用户分组, 也是常用的分组方法。 比如, 在用户终端行为比较统一的情况下, 简单根据用户终端接入系统的时间顺序 进行分组, 如一个用户组 50个用户终端, 一个用户组满了, 下一个接入用户终端就分 到下一个用户组; 再比如, 根据用户终端的无线环境 (网络环境)进行分组, 相同或者 相近无线环境的用户终端可以分在一组。
2 ) 基站为各个用户组配置寻呼参数。
在对用户终端进行分组时, 基站通过不同的寻呼参数配置来区分不同的用户组。 可 以通过设置不同的寻呼组来区分每组用户, 也可以通过设置一个寻呼组内不同的寻呼偏 移来区分每组用户, 也可以通过寻呼组和寻呼偏移结合的方式来区分每组用户。 具体采 用那种方法, 和当前系统具体的用户组数目、 每组用户的数量、 用户的业务需求密切相 关。
其中, 寻呼参数包括寻呼周期和寻呼偏移, 可利用 "寻呼周期 +寻呼偏移"确定当 前寻呼的用户终端, 例如, 设置的寻呼组为 50个, 分别为 groupO、 groupl -grouP49, 设置的寻呼周期为 10s,则在 Ο-lOs内,寻呼 groupO内的用户,在 l l_20s内,寻呼 groupl 内的用户终端, 依此类推; 至于寻呼的具体是哪个 (些)用户终端, 是根据寻呼偏移确 定的。
3 )对每一个用户组中的用户终端, 基站缺省让其先进入 Idle状态, 并通知分配给 它们的寻呼参数。 也即, 基站在完成对用户分组后, 即向用户终端发送空闲状态消息指 示各个用户终端在初始状态下处于 Idle状态, 并在消息中携带上述步骤 2 )为用户终端 所属用户组分配的寻呼参数, 寻呼参数包括寻呼周期和寻呼偏移, 用户终端保存这些参 数。
4) 对每一个用户组, 基站按照给其分配的寻呼参数发起分组寻呼, 并与用户组中 被唤醒的用户终端进行数据传输。
此处基站发起的分组寻呼可以是对一组用户终端统一寻呼, 也可以对每个用户终端 逐一发起寻呼。 其中, 对一组用户终端统一寻呼又进一步包括两种方式, 一是寻呼消息 携带一组用户终端的 ID,该寻呼消息同时对这一组内的一个或多个用户终端发起寻呼唤 醒; 二是寻呼消息携带这一组用户终端的组标识, 表示同时对这一组所有用户终端发起 寻呼唤醒。 逐一发起寻呼就是每次针对一个用户终端发送一条寻呼消息, 指示对该用户 终端发起寻呼唤醒。
通过上述方法, 基站可以根据每组用户终端的业务需求进行分组寻呼唤醒, 并与被 唤醒的用户终端进行数据传输, 从而让所有用户终端最大程度低减少和系统的不必要交 互, 节省用户终端的能耗。
具体寻呼消息, 可以是一条寻呼消息携带 "组索引 (组标识) +用户标识"从而寻 呼组内的一个或多个用户终端, 也可以是一条寻呼消息仅携带组索引, 从而寻呼该组内 的所有用户终端, 这样可以降低寻呼消息的长度, 减少寻呼开销。
请参见图 2, 为本发明实施例携带 "组索引 +用户标识" 的寻呼消息示意图, 其中,
PageGroupID 表示组索引 , PageUserNum 表示用户长度 (寻呼用户终端的数目), UserlGroupIndex表示用户标识, …。 图 2这种方式可寻呼一个用户组, 也可以寻呼多 个用户组, 被寻呼组内的用户终端可以是一个或多个。
请参见图 3, 为本发明实施例仅携带组索引的寻呼消息示意图, 图 3这种方式中的 组索引可以为多个, 即, 同时寻呼多个用户组。
5 ) 用户组中被唤醒的用户终端在收到基站的寻呼消息后, 响应基站的寻呼消息并 返回正常的业务激活状态;
6 ) 在激活状态下, 基站分配下行和上行资源给该用户组中被唤醒的用户终端, 并 与被唤醒的用户终端进行业务数据传输;
7 ) 在完成与被唤醒的用户终端的业务数据传输后, 基站重新指示该用户终端进入
Idle状态; 无论是用户终端入网后初始进入 idle状态, 还是完成业务传输后进入 Idle 状态, 基站即可以逐一让用户终端进入 idle状态, 也可以发起进入 Idle组消息通知一 组用户终端进入 idle状态, 该消息可以指示一组的多个用户终端或者该组内所有用户 终端。
具体地,基站需要重新发送消息指示完成数据传输的用户终端退出激活态进入 Idle 状态; 可以是给每个用户终端发起一条消息指示其进入 Idle状态(逐一指示); 也可以 发送一条消息给一用户组指示这一用户组内的用户终端全部进入 Idle状态 (统一指示); 由于这一用户组具有相同的寻呼参数,所以同时发送给一用户组的消息比单独发送给每 个用户终端要节省较多的开销,是效率更高的做法。对于统一指示消息示例与图 2类似; 对于逐一指示消息示例与图 3类似。
参见图 4, 为用户终端 i与基站的交互流程图, 包括:
S401 : 缺省状态下, 用户终端 i接收基站发送的空闲状态指示消息, 该指示消息包 括为用户终端 i所属用户组分配的寻呼参数 (寻呼周期和寻呼偏移);
S402: 用户终端 i将自身状态设置为 "空闲" (Idle );
S403: 基站根据各个用户组的寻呼参数, 在用户终端 i所属用户组的寻呼周期内, 向该用户组的用户终端发送寻呼消息, 假设, 当前用户终端 i接收到基站发送的寻呼消 自 .
S404: 用户终端 i向基站返回寻呼消息响应;
S405: 用户终端 i将自身状态设置为 "激活";
S406: 用户终端 i通过基站发送给自身的指配消息获知基站为其分配的空口资源;
S407: 用户终端 i与基站之间通过空口资源传输业务数据;
S408: 业务数据传输完成后, 基站向用户终端 i重新发送进入空闲指示消息; S409: 用户终端 i重新将自身设置为 idle状态。
在上述介绍的方案中, 是首先分组寻呼, 再向用户终端分配空口资源, 然后利用空 口资源实现与用户终端的数据传输, 实际上, 可直接在寻呼消息上携带与用户终端交互 的业务数据, 即, 上述步骤 4) -6)可采用以下步骤 s ) 代替:
s ) 对每一组用户终端, 系统也支持直接通过寻呼消息向每一组的用户终端发送下 行业务数据, 每一组的用户终端支持通过寻呼响应消息直接携带上行业务数据, 从而完 成系统和终端交互数据的方式。 系统可以一次给一个或者多个终端发送下行业务数据。
通过 s ) 这种替代方案, 由于省略了为用户终端分配空口资源的步骤, 因此可进一 步减少系统资源的消耗。
另外, 本发明实施例还提供一种寻呼终端的装置, 具体地, 该装置可以是指基站设 备,也可以是指位于基站内部的功能实体,可通过软件、硬件或软硬件结合的方式实现。
请参见图 5, 该装置包括:
空闲状态设置单元 501, 用于为预先分配的用户组配置寻呼参数, 并指示用户组中 的用户终端进入空闲状态;
分组寻呼单元 502, 用于按照寻呼参数向用户组发起分组寻呼唤醒;
数据传输单元 503, 用于与用户组中被唤醒的用户终端进行数据传输。
其中, 空闲状态设置单元 501, 用于在所述数据传输单元 503完成与所述用户组中 的被唤醒用户终端的数据传输后, 指示所述被唤醒的用户终端重新进入空闲状态。
其中, 优选地, 还包括:
分组及配置单元 504, 用于根据用户终端接入系统的时间顺序、 无线环境信息、 用 户终端能力信息, 或 /和, 用户终端的业务 QoS需求信息, 将用户终端划分到对应的用 户组。
其中, 数据传输单元 503的具体实现至少包括以下两种方式: 1 ) 数据传输单元 503可以是嵌入在所述分组寻呼单元 502中的, 在分组寻呼唤醒 过程中与用户终端进行数据传输。
2 )该装置还包括空口资源分配单元 505,用于向用户组中被唤醒的用户终端分配空 口资源; 此时, 数据传输单元 503进一步用于, 利用空口资源与被唤醒的用户终端进行 数据传输。
本领域普通技术人员可以理解, 实现上述实施例的方法的过程可以通过程序指令相 关的硬件来完成, 所述的程序可以存储于可读取存储介质中, 该程序在执行时执行上述 方法中的对应步骤。 所述的存储介质可以如: ROM/RAM、 磁碟、 光盘等。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领域的普通技术人员 来说, 在不脱离本发明原理的前提下, 还可以做出若干改进和润饰, 这些改进和润饰也 应视为本发明的保护范围。
