Description

一种 MTC设备的通信方法 关装置 本申请要求于 2010 年 8 月 13 曰提交中国专利局、 申请号为 201010254197.3、 发明名称为"一种 MTC设备的通信方法及相关装置 "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 本发明涉及通信技术领域, 尤其涉及一种 MTC设备的通信方法及相关 装置。 背景技术 机器类型通信 ( MTC, Machine-Type Communication )应用是指一个或 者多个网元之间在不需要人为参与的情况下进行的网络通讯, 即机器对机 器(M2M, Machine To Machine )应用, 如交通控制与管理、 工厂监控、 远 程抄表等应用。 M2M应用中, 多个具有相同 M2M应用功能的机器对机器设 备( M2ME, Machine To Machine Equipment )组成一个整体,简称群( Group )。
本发明实施例中将参与 MTC应用的用户终端设备称为 MTC设备, 也可 以称为 MTC用户、或者 M2M用户、或者 M2M设备等。该类 MTC设备是针对 MTC应用而进行特殊的物理层、接入层以及非接入层简化的设备。该类 MTC 设备的特点包括: 每一个 MTC设备的交互流量可能非常小, 而且交互可能 是突发的; MTC设备的位置可能是相对固定的, 或者很少移动; MTC设备 所实现的功能相对比较单一, 只需要完成特定的一些信息传输交互, 且一 个特定应用下的 MTC设备的行为是一致的, 例如, 智能抄表业务, 所有的 MTC设备都是在某一特定时间向某一特定服务器上传数据。
在 M2M应用中, MTC设备的数量庞大, 大量 MTC设备如杲接入网络竟 争网络资源, 给现有网络带来了新的负担, 特别是在一些应用场景中, 如 智能抄表业务, 很多国家的智能电网的需求中需要大量的 MTC设备, 以 5 分钟为周期频繁发送上行的抄表数据, 且抄表数据的数据比较小, 大量的
MTC设备需要周期性的频繁的发起上行数据的发送, 且数据量小, 发送时 间相对固定, 对网络造成严重负担。
现有技术中, 为防止大量 MTC设备同时接入网络, 对网络造成的严重 负担, 提出一种在应用层进行分组的方案, 即, 在应用层根据用户的服务 质量(QoS, Quality of Service ) 需求、 上传的目的地址, 或者位置信息等 对 MTC设备进行分组,通过组寻呼来控制同时接入网络的 MTC设备的数量, 避免大量 MTC设备同时接入网络的情况发生。
然而, 由于应用层无法得知 MTC设备驻留的小区信息, 所以应用层的 分组无法保证不同小区内的用户是均衡的。
因此, 现有的基于应用层的分组方案无法保证不同小区内的用户的均 衡, 仍然存在小区内用户集中接入的情况。 发明内容
本发明实施例提供一种 MTC设备的通信方法及相关装置, 避免 MTC设 备集中接入网络对网络造成的负担。

本发明一个实施例提供一种 MTC设备的通信方法, 参照图 1中所示, 包括如下步骤:
步骤 10: 网络侧根据第一 MTC设备接入网络的时间将所述第一 MTC设 备分组, 所述分组满足: 接入网络的时间相同的 MTC设备分在不同组中, 接入网络的时间不同的 MTC设备分在同一组中;
本发明实施例所述第一 MTC设备可以为任意 MTC设备。
其中, 所述第一 MTC设备接入网络的时间包括: 所述第一 MTC设备初 始接入网络的时间; 或根据分組参数确定的所述第一 MTC设备接入网络的 时间。 所述分組参数为网络侧为 MTC设备配置或计算的用于确定 MTC接入 网络时间, 从而可以根据该接入网络的时间进行 MTC设备分组的参数。 该 分组参数可以包括: 网络侧为 MTC设备配置的所述第一 MTC设备的数据发 送周期和每次上发数据的时间单位; 或者, 所述第一 MTC设备的数据发送 周期与每次上发数据的时间单位的比值; 或者, 所述网络侧为同一组内的
MTC设备配置的在数据发送周期内允许上发数据的次数, 由于同一組内的 MTC设备的数据发送周期相同, 所述网络侧为同一组内的 MTC设备配置的 在数据发送周期内允许上发数据的次数, 即网络侧为同一组内的所有 MTC 设备配置的在该组的 MTC设备的一个发送周期内总共可以上发数据的次 数。 所述第一 MTC设备的数据发送周期可以为第一 MTC设备接入网络发送 数据的时间间隔; 所述每次上发数据的时间单位可以为所述第一 MTC设备 发送一次数据持续的时间。
本发明实施例中实现上述配置或计算功能的实体可以为网络侧的基 站, 其中, 数据发送周期可以由网络侧其它实体配置后发送给基站, 继而 由基站发送给第一 MTC设备。
其中,根据所述第一 MTC设备初始接入网络的时间将所述第一 MTC设 备分组的方法可以为: 由于同时接入网络的 MTC设备一定使用不同的接入 资源, 所以可以根据接入资源的使用来识别 MTC设备是否是同时接入网络 的, 本发明实施例对如何识别不做具体限制。 在识别出 MTC设备接入网络 的时间后, 可以将接入网络的时间相同的 MTC设备分在不同组中, 接入网 络的时间不同的 MTC设备分在同一组中。
其中, 根据分组参数确定所述第一 MTC设备接入网络的时间的方法可 以包括:
首先, 获得所述第一 MTC设备的数据发送周期与每次上发数据的时间 单位的比值, 或者获得所述网络侧为同一组内的 MTC设备配置的在数据发 送周期内允许上发数据的次数;其中,若分组参数中包含的为所述第一 MTC 设备的数据发送周期和每次上发数据的时间单位, 则计算所述第一 MTC设 备的数据发送周期与每次上发数据的时间单位的比值。 若分组参数中包含 的为所述第一 MTC设备的数据发送周期与每次上发数据的时间单位的比 值, 则直接利用该比值。 之后, 利用所述第一 MTC设备相关标识对所述比值或所述次数求模, 得到求模结杲; 所述 MTC设备相关标识可以为 MTC设备的国际移动用户识 别码 (IMSI, International Mobile Subscriber Identity )或者根据 IMSI推导出 来的值, 比如 IMSI对某个整数取模的结果;
最后, 确定求模结果相同的 MTC设备同一时间接入网络。
另外, 本发明实施例中网络侧会将所述分組参数发送给所述第一 MTC 设备, 以便所述第一 MTC设备根据分组参数确定所述第一 MTC设备接入网 络的时间。 其中, 网络侧可以在第一 MTC设备接入网络前通过广播的方式 利用系统消息将分組参数发送给第一 MTC设备, 则该第一 MTC设备初始接 入网络的时间即为根据该分组参数确定的第一 MTC设备接入网络的时间; 网络侧也可以在所述第一 MTC设备接入网络后通过专用信令将分组参数发 送给 MTC设备, 则所述第一 MTC设备根据该分组参数确定第一 MTC设备接 入网络的时间为后续接入网络的时间, 也就是不包括该第一 MTC设备初始 接入网络的时间。 所述第一 MTC设备根据分组参数确定第一 MTC设备接入 网络的时间的方法同网络侧根据分组参数确定所述第一 MTC设备接入网络 的时间的方法。 也就是, 本发明实施例中, 网络侧与 MTC设备均按照同样 的方式根据同样的分组参数确定 MTC设备接入网络的时间。
网络侧及第一 MTC设备根据求模结杲确定接入网络的时间的同时, 还 包括: 计算所述第一 MTC设备接入网络的时间所在的帧偏置号及子帧号, 其中
利用 floor(i*p/l 0) ,计算所述第一 MTC设备在本次数据发送周期内的接 入网络的时间所在的帧偏置号;
利用 ( i*p) mod 10 , 计算所述第一 MTC设备在本次数据发送周期内的 接入网络的时间所在的子帧号;
i代表每次上发数据的时间单位, p代表所述第一 MTC设备相关标识对 所述比值或所述次数的求模结杲。 按照本实施例的分组方法, 在每一组中都不存在同时接入网絡的 MTC 设备, 即每一组中的 MTC设备都在不同时间接入网络发送数据, 因此每一 组中的 MTC设备的接入被打散, 有效避免了 MTC设备集中接入对网络造成 的负担。
步骤 11 : 在所述第一 MTC设备接入网络后, 向所述第一 MTC设备发送 分组信息, 以使得所述第一 MTC设备根据所述分组信息进行数据接收和 /或 发送。
本发明实施例中, 为所述第一 MTC设备分组后, 在所述第一 MTC设备 接入网络后下发分組信息给所述第一 MTC设备, 以使得所述第一 MTC设备 根据所述分组信息进行数据接收和 /或发送。 所述分组信息包括以下至少一 个: 组寻呼标示信息(GP-RNTI: Group paging Radio Network Temporary Identifier ) 、 公共的小区无线网络临时标识(C-RNTI, cell Radio Network Temporary Identifier或 MTC-RNTI ), 及公共的无线 载(RB, radio bearer ) 信息。
本发明实施例中所述第一 MTC设备根据所述分組信息进行数据接收 和 /或发送包括: 当所述第一 MTC设备收到 GP-RNTI后, 所述第一 MTC设备 可以不立即回寻呼响应信息, 而是在到达该第一 MTC设备的接入网络时刻 后接入网络, 进行寻呼响应的发送, 以减少多个 MTC设备同时接入网络对 网络的冲击。
当所述第一 MTC设备收到公共 C-RNTI或 MTC-RNTI或公共 RB信息 后, 使用该信息进行数据的传输处理。 即同一组内的多个 MTC设备使用相 同的 C-RNTI或 MTC-RNTI作为连接标示, 在获取的公共 RB上进行数据的发 送和 /或接收。这里的公共 RB可以是組共用的专用 RB或者组共用的公共 RB。
本发明实施例执行主体为网络侧设备, 如基站, 演进基站等。
本发明实施例通过将同一时间接入的 MTC设备分在不同組中, 同一组 中的各 MTC设备在不同时间接入网络, 实现了分散 MTC设备接入网络发送 数据的时机, 避免碰撞, 有效减轻 MTC设备集中接入对网络造成的负担。 同时, 本发明实施例解决了现有技术中应用层随机化分组方法所不能解决 的各个小区间接入用户数目不均衡的问题。 为进一步理解本发明上述实施例, 下面以具体实例对本发明提供的 MTC设备接入网络的方法进行详细阐述。
实例一
如图 2中所示, 包括如下步骤:
步骤 20: MTC设备接入网络前, eNB通过广播方式发送分組参数给 MTC设备;
所述分组参数包括: MTC设备的数据发送周期 T和每次上发数据的时 间单位 i; 或该分组参数包括: 参数 N, N=MTC设备的数据发送周期 T/每次 上发数据的时间单位 i; 或该分组参数包括: 所述网络侧为同一組内的 MTC 设备配置的在数据发送周期内允许上发数据的次数 N'。
步骤 21: 计算 MTC设备接入网络的时间;
eNB和 MTC设备均根据 MTC设备的 IMSI和 N值计算 MTC设备接入网 络的时间, 计算方法为:
N=T/i;
P= IMSI mod ; ϋΡ= IMSI mod N,;
MTC设备在本次数据发送周期内的接入网络的时刻所在的帧偏置号 为: floor(i*p/10)] ;
MTC设备在本次数据发送周期内的接入网络的时刻所在的子帧号为: x= ( i*p) mod 10;
其中, p值相同的 MTC设备在同一时间接入网络;
步驟 22: 将同一时间接入网络的 MTC设备分在不同组中, 不同时间接 入网络的 MTC设备分在同一组中, 在 MTC设备按照计算的接入时间接入网 络后, eNB下发分组信息给 MTC设备;
为了不发生碰撞, 将 p值相同的 MTC设备分在不同的组中, eNB记录 分组信息, 并对每个组分配共享的连接。
本发明实施例中, 将每个发送周期在时间上分为多个时段, 通过 MTC 设备的 IMSI相关标识对 N取模的运算将 MTC设备分散到各个发送时段中 去, 把分布到不同发送时段的 MTC设备划分到一个组, 这样可以保证每个 组内的 MTC设备在不同的时段接入或者发送数据。
分组方法举例如下:
假设 T=300ms, i=100ms, 则 N=3
根据本发明的分组方法, 可以推得网絡多 MTC设备的一种实施例分组 如图 3中所示, 假设 MTC设备 1、 MTC设备 2、 MTC设备 3模 N后都为 1 , 他们 都是在时段 1发送数据, 同样, MTC设备 4、 MTC设备 5、 MTC设备 6在时段 2发送数据, MTC设备 7、 MTC设备 8、 MTC设备 9在时段 3发送数据, 所以 在分组的时候, 将在同一时段发送数据的 MTC设备分配到不同的组中。
将在不同时间段接入的 MTC设备分到一个组内, 比如将在时段 1发送 数据的 MTC设备 1, 时段 2发送数据的 MTC设备 4和时段 3发送数据的 MTC7 分到组 1内。 当然还可以将在时段 1发送数据的 MTC设备 1, 时段 2发送数据 的 MTC设备 5和时段 3发送数据的 MTC设备 9分到相同的組内,只要同一个組 内的不同的 MTC设备在不同的时间接入网络即可。
在 MTC设备按照计算的接入时间初始接入网络后, eNB下发分组信息 给 MTC设备。
所述分组信息包括: GP-RNTI , 公共的小区无线网络临时标识 ( C-RNTI或 MTC-RNTI )和 /或公共的无线 7 载(RB, radio bearer )信息。
本发明实施例实现了在无线接入网络( RAN , Radio Access Network ) 侧对 MTC设备的接入及数据传输进行分组, 使得在基于組的无线资源控制 ( RRC, Radio Resource Control )链接管理的场景下能够分散 MTC设备发送 数据的时机, 避免碰撞, 以及对网络造成负担。 实例二
如图 4所示, 包括如下步骤:
步骤 40: 在 MTC设备接入网络后, eNB通过专用信令下发分组参数给 MTC设备;
所述分組参数包括: MTC设备的数据发送周期 T和每次上发数据的时 间单位 i; 或该分组参数包括: 参数 N, N=MTC设备的数据发送周期 T/每次 上发数据的时间单位 i; 或该分组参数包括: 所述网络侧为同一組内的 MTC 设备配置的在数据发送周期内允许上发数据的次数 N,。
步骤 41: 计算 MTC设备接入网络的时间;
eNB和 MTC设备均根据 MTC设备的 IMSI和 N值计算 MTC设备接入网 络的时间, 计算方法为:
N=T/i;
P= IMSI mod N; ^P= IMSI mod N';
MTC设备在本次数据发送周期内的接入网络的时刻所在的帧偏置号 为: floor(i*p/10)] ;
MTC设备在本次数据发送周期内的接入网络的时刻所在的子帧号为: x= ( i*p) mod 10;
其中, p值相同的 MTC设备在同一时间接入网络;
步骤 42: 将同一时间接入网络的 MTC设备分在不同组中, 不同时间接 入网络的 MTC设备分在同一组中, 下发分组信息给 MTC设备;
为了不发生並撞, 将 p值相同的 MTC设备分在不同的组中, 将在不同 时间段接入的 MTC设备分到一个组内, eNB记录分组信息, 并对每个组分 配共享的连接, 使所述 MTC设备根据所述分组信息进行数据接收和 /或发 送。 本发明实施例中, 将每个发送周期在时间上分为多个时段, 通过 MTC 设备的 IMSI相关标识对 N取模的运算将 MTC设备分散到各个发送时段中 去, 把分布到不同发送时段的 MTC设备划分到一个组, 这样可以保证每个 组内的 MTC设备在不同的时段接入或者发送数据。
所述分组信息包括: GP-RNT 公共的小区无线网络临时标识( C-RNTI 或 MTC-RNTI )和 /或公共的无线承载(RB, radio bearer )信息。
MTC设备后续按照计算的接入时间接入网络。
本发明实施例实现了在 RAN侧对 MTC设备的接入及数据传输进行分 組, 使得在基于组的 RRC链接管理的场景下能够分散 MTC设备发送数据的 时机, 避免碰撞, 以及对网络造成负担。 实例三
如图 5所示, 包括如下步骤:
步 50: MTC设备接入网络后, eNB根据 MTC设备初始接入网络的时 间将 MTC设备分组, 其中相同时间接入的 MTC设备分在不同组中, 不同时 间接入网络的 MTC设备分在同一组中;
由于每个 MTC设备都是每隔一定周期固定的上发数据, MTC设备第一 次接入网络时, eNB根据接入的 MTC设备的情况,将在同一时刻接入的 MTC 设备分配到不同的 RAN侧分组里, 这样保证在一个组内的 MTC设备在后续 使用公共 RB的数据发送过程中不会发生碰撞。
MTC设备在初始接入网络时, 如果有其他 MTC设备同时接入, 则 eNB 将同时接入的 MTC设备分到不同的 RAN组中, 令同一组中的各 MTC设备在 不同时间接入网络; 由于同时接入网络的 MTC设备一定使用不同的接入资 源,所以可以根据接入资源的使用来识別 MTC设备是否是同时接入网络的, 本发明实施例对如何识别不^:具体限制。
步骤 51: 下发分组信息给 MTC设备; eNB可通过专用信令为同一组的 MTC设备分配相同的分组信息下发给 MTC设备, 如, GP-RNTL 公共的 C-RNTI或 MTC-RNTI或公共的 RB信息。 eNB记录该分組信息。
本发明实施例中, 由于各 MTC设备是低移动性, 而且各个 MTC设备后 续按照规定的时间间隔进行接入, 因此可以重用已经形成的组。
本发明实施例实现了在 RAN侧对 MTC设备的接入及数据传输进行分 组, 使得在基于组的 RRC链接管理的场景下能够分散 MTC设备发送数据的 时机, 避免碰撞, 以及对网络造成负担。 为实施本发明上面实施例所述的 MTC设备的通信方法, 本发明一实施 例提供一种网络装置, 如图 6所示, 包括:
