Description

网络设备、用户设备和接入网络的方法 技术领域
本发明涉及通信领域，并且更具体地，涉及网络设备、用户设备和接入网络的方法。
背景技术
低复杂度用户设备(Low Complexity User Equipment)是一类特殊的用户设备(User Equipment简称为UE)。相对普通的UE，低复杂度终端具有比较低的处理复杂度，因而一般更低的成本。例如包括水表、电表等的一些机器类通信终端(Machine Type Communication Terminal)。这类终端一个重要的特征是仅可以接收窄带(如1.4M带宽)内的基带数据，且每个传输时间间隔(Transmission Time Interval，简称为TTI)的传输块需要限制在一个阈值(如200比特)以内，超过此阈值的数据包，只能拆分成该阈值以内的传输块来传输。
现有技术中，用户设备在接入网络的过程中，网络设备会向用户设备发送无线资源控制(Radio Resource Control，简称为RRC)连接建立消息，RRC连接建立消息主要包含无线资源配置信息，而无线资源配置信息中，又进一步包括信令无线承载配置、媒体接入控制(Media Access Control，简称为MAC)配置、物理层配置等内容。由于这些配置的具体内容很多，导致RRC连接建立消息较大，一般大于200比特。并且网络设备采用无线链路控制透明模式(Radio Link Control Transparent Mode，简称为RLC TM)传输RRC连接建立消息。RLC TM模式传输的特点是不允许对要传输的数据包进行分段传输，也就是说整个数据包必须以一个传输块传输。对于低复杂度UE而言，由于不能接收大于一个阈值(如200比特)的传输块，而RRC连接建立消息又不允许被分段传输，所以导致低复杂度UE无法接收此RRC连接建立消息。

具体实施方式
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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，在本发明实施例中，用户设备也可称之为终端设备(Terminal Equipment)、移动台(Mobile Station，简称为MS)、移动终端(Mobile Terminal) 等，该用户设备可以经无线接入网(Radio Access Network，简称为RAN)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，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言和/或数据。
在本发明实施例中，网络设备可以是基站、增强型基站、小区或中继等。其中，基站可以是GSM或CDMA中的基站(Base Transceiver Station，简称为BTS)，也可以是WCDMA中的基站(NodeB，简称为NB)，还可以是LTE中的演进型基站(Evolutional Node B，简称为ENB或e-NodeB)，本发明并不限定，但为描述方便，下述实施例将以ENB为例进行说明。
在本发明实施例中，核心网设备可以是移动性管理实体(Mobility Management Entity，简称为MME)，还可以是服务网关(Serving Gateway，简称为S-GW)或分组数据网关(PDN Gateway，简称为P-GW)，本发明并不限定，为了描述方便，下述实施例将以MME为例进行说明，但本发明并不限于此。
图1示出了本发明实施例的一种应用场景的示意性架构图。应注意，图1的例子是为了帮助本领域技术人员更好地理解本发明实施例，而非限制本发明实施例的范围。
如图1所示，LTE通信系统架构可以包括：UE、演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network，简称为E-UTRAN；其中通用移动通信系统(Universal Mobile Telecommunications System)简称为UMTS)、移动性管理实体(Mobility Management Entity，简称为MME)、服务网关(Serving Gateway，简称为SGW)、分组数据网络网关(Packet Data Network Gateway，简称为PGW)、策略和计费规则功能(Policy and Charging Rule Function，简称为PCRF)、归属用户服务器(Home Subscriber Server，简称为HSS)、服务通用分组无线业务支持节点(Serving GPRS Supporting Node，简称为SGSN)。MME是移动性管理网元，负责非接入层(Non-Access Stratum，简写为NAS)信令加密、为UE分配临时身份标识、选择SGW和PGW等核心网网元、提供漫游、跟踪、安全等功能；SGW是本地eNB之间切换的移动性锚点，并提供合法监听相关功能；PGW则负责用户地址分配、策略控制和计费规则的执行以及合法监听相关等功 能；HSS用于存储用户的签约信息；PCRF用于提供策略和计费控制规则。
具体而言，PGW为连接提供服务的PDN网络(该网络可能是运营商内部或外部的分组网络)的网关，负责对用户数据流进行转发和过滤等；SGW主要负责在UE和PGW之间中继用户业务流，以及在网络设备间切换时作为锚定点；PCRF用于根据用户接入网络的限制、运营商策略、用户签约数据以及用户当前正在进行的业务信息等决定对应的策略，并将该策略提供给传输网关执行，从而实现策略计费控制；MME主要完成E-UTRAN接入下的UE的移动性管理、会话管理、NAS信令的加密和完整性保护、PGW/SGW的选择等功能，另外当UE处于空闲(Idle)态时，MME可保存承载上下文信息；SGSN主要完成GERAN/UTRAN接入下的UE的移动性管理、会话管理等功能，另外当UE处于Idle态时，SGSN也可保存承载上下文信息。
应理解，本发明实施例将以应用于LTE系统为例进行说明，但本发明并不限于此。另外，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
图2示出了本发明实施例的网络设备10的示意性框图，如图2所示，该网络设备10包括：接收模块11，处理模块12，以及发送模块13，其中，
该接收模块11，用于接收用户设备发送的随机接入前导码；
该处理模块12，用于在该接收模块接收到该随机接入前导码后，控制该发送模块13向该用户设备发送随机接入响应；
该发送模块13，用于向该用户设备发送随机接入响应；
该接收模块11，还用于在该发送模块13向该用户设备发送该随机接入响应后，接收该用户设备发送的用于建立网络连接的请求消息；
该处理模块12，还用于在该接收模块11接收到该请求消息后，确定该用户设备的类型为目标类型，控制该发送模块13向该用户设备发送竞争解决媒体接入控制控制单元MAC CE，以及采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置；
该发送模块13，还用于向该用户设备发送竞争解决媒体接入控制控制单元MAC CE。
具体而言，网络设备接收用户设备发送随机接入前导码，在接收到该随机接入前导码后，向该用户设备发送随机接入响应，之后，接收用户设备发送的用于建立网络连接的请求消息，网络设备在确定该用户设备的类型为目标类型时，向该用户设备发送竞争解决媒体接入控制控制单元MAC CE，并采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。
因此，本发明实施例的网络设备，接收到用户设备发送的用于建立网络连接请求消息后，在确定该用户设备的类型为目标类型时，向该用户设备发送竞争解决媒体接入控制控制单元MAC CE。因此，可以避免RRC连接建立消息太大和现有技术中默认配置信息对应的默认配置不适用于目标类型的用户设备的问题。从而，该目标类型的用户设备在通信过程中可以成功进行无线资源配置，完成与网络设备间的信令交互。
在本发明实施例中，可选地，目标类型对应的用户设备可以指接收带宽小于第一阈值的用户设备；和/或，每个传输时间间隔(Transmission Time Interval，简称为TTI)的传输块小于第二阈值的用户设备；和/或，接收到的网络设备发送的信号强度小于第三阈值的用户设备；和/或接收到的网络设备发送的信号质量小于第四阈值的用户设备。其中，该第一阈值、该第二阈值、该第三阈值和该第四阈值可以为符合通信标准的任意值。例如在现有LTE系统中，该第一阈值可以为小于20M的任意数值，所以该接收带宽可以为1M、3M、8M、15M等。该第二阈值可以为200比特、300比特或任意一个数值。该第三阈值可以为-20dBm、-30dBm、-35dBm等，该第四阈值可以为-50dB、-60dB、-65dB等。本发明对此不作限定。
在本发明实施例中，可选地，目标类型对应的用户设备还可以是具有低制造成本的低成本用户设备；和/或，需要长时间工作，但又不方便充电或更换电池的需要节电的用户设备；和/或，相关技术中的类型0的用户设备。
在本发明实施例中，可选地，该接收模块11接收的随机接入前导码与用户设备的类型对应。相应地，该处理模块13可以根据该随机接入前导码确定用户设备的类型。
在本发明实施例中，可选地，在该接收模块11接收到该用户设备发送的该随机接入前导码之前，该发送模块13还用于：向用户设备发送该默认的无线资源配置信息。
在本发明实施例中，可选地，该接收模块11接收的该请求消息包括第 二指示信息，该第二指示信息用于指示该用户设备的类型。相应地，该处理模块12可以通过该接收模块11接收的该请求消息中包括的第二指示信息，确定该用户设备的类型。
具体而言，接收模块11接收的该请求消息中包括的RRC连接建立请求消息中包括该第二指示信息，该第二指示信息具体指示用户设备的类型；或该请求消息的逻辑信道标识可以用来指示用户设备的类型；或该请求消息包括预留比特位，通过该预留比特位指示用户设备的类型，例如，该预留比特位可以包括1个比特，其中，“0”指示用户设备的类型为普通类型，“1”指示用户设备的类型为目标类型，但本发明并不限于此。
在本发明实施例中，可选地，在该用户设备的类型为目标类型时，该发送模块13还用于：向该用户设备发送包括第一指示信息的无线资源控制RRC连接建立消息，该第一指示信息用于指示该用户设备采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。
具体而言，网络设备向用户设备发送RRC连接建立消息，该RRC连接建立消息除包括消息名称、处理标识、要增加或修改的信令无线承载列表、信令无线承载标识等信息外，还包括用于指示该用户设备采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置的第一指示信息。其中，该第一指示信息可以指示具体是哪一种配置要采用该与目标类型对应的默认的无线资源配置信息进行无线资源配置，也可以指示具体是采用哪一种与该目标类型对应的默认的无线资源配置信息进行无线资源配置，本发明对此不作限定。
在本发明实施例中，可选地，在该处理模块12根据该接收模块11接收的与用户设备的类型对应的随机接入前导码或根据请求消息中包括的该第二指示信息确定用户设备的类型为目标类型时，在RRC连接建立消息包括无线资源配置的具体配置内容时，该发送模块13也可以采用RLC UM发送模式，向用户设备发送RRC连接建立消息，用户设备采用RLC UM模式接收该RRC连接建立消息。由于RLC UM发送模式允许将消息进行分段传输，因此可以避免RRC连接建立消息内容过长的问题，从而目标类型的用户设备可以成功接收该RRC连接建立消息，并根据该RRC连接建立消息中包括的具体配置信息进行无线资源配置。
因此，本发明实施例的网络设备，接收到用户设备发送的用于建立网络 连接的请求消息后，在该用户设备的类型为目标类型时，向该用户设备发送竞争解决媒体接入控制控制单元MAC CE，以便于该用户设备接收到该MAC CE后，采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。因此，可以避免RRC连接建立消息太大和现有技术中的默认配置信息对应的默认配置不适用于目标类型的用户设备的问题。从而，该目标类型用户设备在通信过程中可以成功进行无线资源配置，完成与网络设备间的信令交互。
在本发明实施例中，可选地，网络设备和用户设备之间可以按照预定规则进行信令交互，可以将用户设备的所有的无线资源配置信息都配置为与用户设备的类型对应的默认的配置，由此发送模块13可以仅向用户设备发送竞争解决媒体接入控制控制单元MAC CE，而不需要向用户设备发送RRC连接建立消息，用户设备在接收到该MAC CE后，可以根据该MAC CE解决接入竞争，在解决接入竞争之后采用默认的无线资源配置信息进行无线资源配置。
因此，本发明实施例的网络设备，接收到用户设备发送的用于建立网络连接的请求消息后，在该用户设备的类型为目标类型时，仅向该用户设备发送MAC CE，该用户设备在接收到该MAC CE后，采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。因此，可以不向用户设备发送RRC连接建立消息，可以避免RRC连接建立消息内容过长的问题和现有技术中的默认配置信息对应的默认配置不适用于目标类型的用户设备的问题。从而，该目标类型用户设备在通信过程中可以成功进行无线资源配置，完成与网络设备间的信令交互，并可以降低通信过程中的无线资源耗费。
在本发明实施例中，可选地，该与目标类型对应的默认的无线资源配置信息，可以是根据不同的通信标准预先设置，并配置在网络设备和用户设备内部的默认的无线资源配置信息，对应于某一目标类型的用户设备，该预设的无线资源配置信息可以有多种。该与目标类型对应的无线资源配置信息也可以是网络设备对不同的配置进行预先设置后，向用户设备发送的无线资源配置信息，对于某一目标类型的用户设备该无线资源配置信息可以有多种。例如，网络设备可以向用户设备发送广播消息，广播消息中携带与用户设备的类型对应的无线资源配置信息，该无线资源配置信息包括与用户设备的类型对应的每种无线资源配置的具体配置方式。但本发明并不限于此。
在本发明实施例中，可选地，可以对现有技术中没有默认配置的配置信息(例如：信道状态信息、调度请求定时器等)，增加与目标类型匹配的默认配置。也可以将现有技术中已有的默认配置信息，设置成与目标类型的用户设备更匹配的配置信息。例如，可以将MAC配置中的最大混合自动重传请求HARQ传输的次数设置为2次(现有技术中为5次)，可以将物理信道配置中的天线传输模式设置为传输模式1(现有技术中的传输模式可以为1或2)。但本发明并不限于此。
在本发明实施例中，可选地，该默认的无线资源配置信息可以包括下列信息中的至少一种：信令无线承载配置信息、媒体接入控制MAC配置信息和物理层配置信息。具体而言，用户设备可以根据与用户设备的类型对应的默认的信令无线承载配置信息进行信令无线承载配置，可以根据与用户设备的类型对应的默认的媒体接入控制MAC配置信息进行MAC配置，还可以采用与用户设备的类型对应的默认的物理层配置信息进行物理层配置，本发明对此不作限定。
因此，本发明实施例的网络设备，接收到用户设备发送的用于接入网络的请求消息后，在该用户设备的类型为目标类型时，向该用户设备发送竞争解决媒体接入控制控制单元MAC CE，以便于该用户设备接收到该MAC CE后，采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。因此，可以避免RRC连接建立消息太大和现有技术中的默认配置信息对应的默认配置不适用于目标类型的用户设备的问题。从而，该目标类型用户设备在通信过程中可以成功采用与该目标类型对应的默认的无线资源配置与网络设备进行信令交互。
上文结合图2详细描述了本发明实施例的网络设备，下面将结合图3详细描述本发明实施例的用户设备。

在本发明实施例中，可选地，在RRC连接建立消息包括无线资源配置 的具体配置内容时，该接收模块23还可以采用RLC UM模式接收网络设备采用RLC UM发送模式发送的RRC连接建立消息，由于RLC UM发送模式允许将消息进行分段传输，可以避免RRC连接建立消息内容过长的问题，从而目标类型的用户设备可以成功接收该RRC连接建立消息，根据该RRC连接建立消息中包括的具体配置信息进行无线资源配置。
因此，本发明实施例的用户设备，向网络设备发送用于建立网络连接的请求消息，并接收网络设备接收该网络设备发送的竞争解决媒体接入控制控制单元MAC CE，接收到该MAC CE后，采用与该用户设备的类型对应的默认的无线资源配置信息进行无线资源配置。因此，可以避免RRC连接建立消息太大和现有技术中的默认配置信息对应的默认配置不适用于目标类型的用户设备的问题。从而，该用户设备在通信过程中可以成功进行无线资源配置，完成与网络设备间的信令交互。
在本发明实施例中，可选地，网络设备和用户设备之间可以按照预定规则进行信令交互，用户设备的所有的无线资源配置信息都可以配置为与用户设备的类型对应的默认的配置，由此接收模块23可以仅接收网络设备发送的竞争解决媒体接入控制控制单元MAC CE，用户设备在接收到该MAC CE后，可以根据该MAC CE解决接入竞争，在解决接入竞争之后采用该默认的无线资源配置信息进行无线资源配置。
因此，本发明实施例的用户设备，向网络设备发送用于建立网络连接的请求消息，之后，用户设备仅接收该网络设备发送的竞争解决媒体接入控制控制单元MAC CE，接收到该MAC CE后，采用与该用户设备的类型对应的默认的无线资源配置信息进行无线资源配置。因此，可以避免RRC连接建立消息内容过长的问题和现有技术中的默认配置信息对应的默认配置不适用于目标类型的用户设备的问题。从而，该用户设备在通信过程中可以成功进行无线资源配置，完成与网络设备间的信令交互。
在本发明实施例中，可选地，该与用户设备的类型对应的默认的无线资源配置信息，可以是根据不同的通信标准预先设置，并配置在网络设备和用户设备内部的默认的无线资源配置信息，对应于某一目标类型的用户设备，该预设的无线资源配置信息可以有多种。该与用户设备的类型对应的无线资源配置信息也可以是网络设备对不同的配置进行预先设置后，向用户设备发送的无线资源配置信息，对于某一目标类型的用户设备该无线资源配置信息 可以有多种。例如，网络设备可以向用户设备发送广播消息，广播消息中携带与用户设备的类型对应的无线资源配置信息，该无线资源配置信息包括与用户设备的类型对应的每种无线资源配置的具体配置方式。但本发明并不限于此。
在本发明实施例中，可选地，该默认的无线资源配置信息包括下列信息中的至少一种：信令无线承载配置信息、媒体接入控制MAC配置信息和物理层配置信息。具体地，用户设备可以根据与该用户设备的类型对应的默认的信令无线承载配置信息进行信令无线承载配置，可以根据与该用户设备的类型对应的默认的媒体接入控制MAC配置信息进行MAC配置，还可以根据与该用户设备类型对应的默认的物理层配置信息进行物理层配置，本发明对此不作限定。

S140，确定该用户设备的类型为目标类型；
S150，向该用户设备发送竞争解决媒体接入控制控制单元MAC CE，并采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。
具体而言，网络设备接收用户设备发送随机接入前导码，在接收到该随机接入前导码后，向该用户设备发送随机接入响应，之后，接收用户设备发送的用于建立网络连接的请求消息，网络设备在确定该用户设备的类型为目标类型时，向该用户设备发送竞争解决媒体接入控制控制单元MAC CE，并采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。
因此，本发明实施例的接入网络的方法，网络设备在接收到用户设备发送的用于建立网络连接请求消息后，在确定该用户设备的类型为目标类型时，向该用户设备发送竞争解决媒体接入控制控制单元MAC CE，以便于该用户设备接收到该MAC CE后，采用与该目标类型对应的默认的无线资源配置信息进行无线资源配置。因此，可以避免RRC连接建立消息太大和现有技术中的默认配置信息对应的默认配置不适用于目标类型的用户设备的问题。从而，该目标类型用户设备在通信过程中可以成功进行无线资源配置，完成与网络设备间的信令交互。
在本发明实施例中，可选地，目标类型对应的用户设备可以指接收带宽小于第一阈值的用户设备；和/或，每个传输时间间隔(Transmission Time Interval，简称为TTI)的传输块小于第二阈值的用户设备；和/或，接收到的网络设备发送的信号强度小于第三阈值的用户设备；和/或接收到的网络设备发送的信号质量小于第四阈值的用户设备。其中，该第一阈值、该第二阈值、该第三阈值和该第四阈值可以为符合通信标准的任意值。例如在现有LTE系统中，该第一阈值可以为小于20M的任意数值，所以该接收带宽可以为1M、3M、8M、15M等。该第二阈值可以为200比特、300比特或任意一个数值。该第三阈值可以为-20dBm、-30dBm、-35dBm等，该第四阈值可以为-50dB、-60dB、-65dB等。本发明对此不作限定。
