Description

系统消息处理方法及网络设备、用户终端 技术领域
本发明涉及通信技术领域，尤其涉及一种系统消息的处理方法及网络设备、用户终端。本发明的实施例涉及使用小区簇的系统消息处理方法及其网络设备和用户终端。
背景技术
伴随移动宽带(MBB)的迅猛发展和智能手机的普及，移动互联网正迅速而深入地改变和丰富着人们的生活。华为mLAB的无线网络统计数据表明，全球移动数据流量年复合增长率高达67％，同时网络流量的分布极度不平衡，热点区域的容量需求呈现出爆炸式增长。
基于上面的需求，为实现对热点地区提供较高的系统容量，通常在热点地区架设微小区，通过微小区对热点地区的移动用户提供业务，从而使得移动通信网络通常为多层小区结构(heterogeneous network，HetNet)。随着网络的不断演进，网络的结构会越来越复杂，网络之间的相互覆盖会越来越普遍。在一种可能的实现方式中，使用宏基站创建宏小区(macro-cell)实现大范围的连续网络覆盖，然后在热点地区使用大量的稠密的微基站创建微小区进行重叠覆盖，微小区提供较高的系统容量。特别是，系统消息作为常见的基础性消息，通常需要在小区内进行广播。当多个小区会发送系统消息时，不仅会造成资源的浪费，在小区的重叠部分甚至会造成资源的冲突。对于用户终端而言，需要接受每个小区的系统消息，在解析这些过多的系统消息过程中也会造成较长的等待。所以，现有的系统消息的处理机制无法满足多层小区部署场景的需求。
发明内容
本文提供了一种系统消息的处理机制，以实现多层小区部署场景下对系统消息的处理。
一方面，本申请的实施例提供一种处理系统消息的方法。方法包括网络设备确定带有至少一个小区簇信息的系统消息，所述小区簇包括至少一个小区的集合；所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他信息中的至少一个信息或者其组合；所述网络设备发送所述带有小区簇信息的系统消息。对应的，用户终端按照与网络设备对应的处理方式，接收带有至少一个小区簇信息的系统消息，进而可以选择一个小区。因为小区簇的引入，系统信息的调度变得灵活而可靠。
在一个可能的设计中，所述网络设备通过以下至少一种方式发送所述带有小区簇信息的系统消息：广播，组播，专用信令。这样带有小区簇信息的系统消息可以以多种方式发送出去。所述小区簇可以是至少两个小区的集合。小区一般有对应于该小区的网络设备。则可以有如下的情况，所述网络设备为第一网络设备，所述第一网络设备所发送的系统消息，包含第二网络设备的系统信息，所述第二网络设备不同于第一网络设备。这样第一网络设备的系统消息发送了第二网络设备的系统信息，而该信息可以通过系统消息中的小区簇信息来完成。可选的，所述小区簇信息的小区对应的网络节点与所述网络设备有相同的覆盖区域，或该网络节点与所述网络设备相邻。所述网络设备也可以是所述小区簇信息的一个或多个小区对应的网络节点。这样，多层小区中小区的层数或者小区的数量越多，不同小区的系统信息可以通过某一个或者某几个网络设备集中发送，使得系统信息的调度更加灵活和可靠。
在一个可能的设计中，小区簇的特征信息包含该小区簇中小区所具有的突出特性。所述小区簇的特征信息包括以下信息的至少一种：载波频率信息，带宽信息，小区支持的业务特性信息，小区支持的功能特性信息,无线接入类型信息，波束成型配置信息，随机接入信息，位置信息，同步信息，小区簇 的小区的系统信息块(system Information Blocks，SIB)块对应的RNTI和小区簇的小区的系统消息资源。所述小区簇的公共信息包括小区簇中小区的相同的信息，包括以下至少一个信息：公共陆地移动网络(public land mobile network，PLMN)标识(ID),跟踪区编码(track area code，TAC),全球小区识别码(cell global identifier，CGI)，载波频率信息，带宽信息，小区是否禁用的信息。所述小区簇的接入信息包括所述小区簇中的至少一个小区的接入信息，包括以下至少一个信息：公共陆地移动网络(public land mobile network，PLMN)标识(ID),跟踪区编码(track area code，TAC),全球小区识别码(cell global identifier，CGI)，载波频率信息，带宽信息，随机接入信息，工作模式信息,小区的逻辑信道配置信息，小区的物理信道和信令配置信息，小区的信令配置信息，定时器信息,循环前缀(cyclic prefix,CP)长度,功率控制信息。上述小区簇的特征信息、公共信息、接入信息、其他信息仅仅是举例说明，各个信息的设置可以存在重复的情况。这要根据系统情况的不同来不同设置。通过上述信息的不同设置可以更灵活地调度系统信息。可以理解的，所述小区簇信息中可以包含该小区簇的标识信息。
在一个可能的涉及中，系统信息块可以采取不同的发送方式，包括而不限于：一个系统信息块SIB包含多个小区簇的小区簇信息；一个SIB包含一个小区簇的小区簇信息，不同的SIB包含不同的小区簇信息；第一SIB包含一个小区簇信息的第一信息，第二SIB包含该小区簇信息的第二信息，所述第一信息和所述第二信息是该小区簇信息的特征信息、公共信息、接入信息、其他信息中的一个，所述第一信息不同于所述第二信息；第一SIB包含多个小区簇信息的第一信息，第二SIB包含该多个小区簇信息的第二信息，所述第一信息和所述第二信息是该多个小区簇信息的特征信息、公共信息、接入信息、其他信息中的一个，所述第一信息不同于所述第二信息；SIB包含小区簇信息的SIB的调度信息，其中调度信息包括以下信息中的至少一种：调度 周期，小区簇信息的SIB的时域信息，小区簇信息的SIB的频域信息。通过不同设置方式，可以提供不同的调度形式，以满足不同场景下对系统信息的需求。
为了优先调度重要的信息，后调度相对不重要的信息，可以对不同的小区簇信息，即小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他信息，采用不同的调度周期。如，小区簇信息的特征信息的调度周期小于该小区簇信息的公共信息的调度周期，接入信息的调度周期和其他信息的调度周期中的一个；小区簇信息的其他信息的调度周期大于该小区簇信息的特征信息的调度周期，公共信息的调度周期，接入信息的调度周期和其他信息的调度周期中的一个；小区簇信息的公共信息的调度周期大于该小区簇信息的特征信息的调度周期和接入信息的调度周期中的一个。
本发明实施例提供的基于小区簇信息的系统消息处理方式，可以确定用户终端需要的小区簇或其小区，这样，为网络设备和用户终端的系统消息的传递建立了快捷准确的沟通渠道。
另一方面，本申请的实施例提供一种处理系统消息的方法。方法包括网络设备确定需要更新的系统信息对应的小区簇，所述小区簇包括至少一个小区的集合，所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他信息中的至少一个信息或者其组合；发送指示信息，所述指示信息指示小区簇的系统消息发生改变，或者小区簇的系统消息是否发生改变。对应的，用户终端按照与网络设备对应的处理方式，获取指示信息，所述指示信息指示小区簇的系统消息发生改变，或者小区簇的系统消息是否发生改变，确定当前使用的小区簇信息是否需要更新。因为小区簇的引入，系统信息的更新变得灵活而可靠。
在一个可能的设计中，所述指示信息可以采用不同的形式，或者可以指示小区簇中的小区的系统消息发生改变，或者可以指示小区簇中的小区的系 统消息是否发生改变。这可以有通信双方预先确定，使得系统信息的更新更灵活。
在一个可能的设计中，所述指示信息可以由系统消息或者系统信息更新消息携带。这根据通信双方的约定来确定，即采用系统消息或者不采用系统消息的渠道来完成。
在一个可能的设计中，所述指示信息可以是网络设备配置的小区簇的索引号，网络设备在发送的用于调度系统信息更新消息的物理控制信道中携带所述指示信息；或者，所述指示信息是网络设备配置的小区簇对应的网络临时标识(radio network temporary identifier，RNTI)，网络设备在发送的用于调度系统信息更新消息的物理控制信道时用所述指示信息做循环冗余校验(cyclic redundancy check,CRC)操作；或者，所述指示信息是网络设备配置的小区簇对应的信道配置参数，网络设备利用所述指示信息中信道配置参数，配置系统信息更新消息的物理控制/数据信道；或者，所述指示信息是网络设备配置的小区簇对应的系统更新消息所发送的时域和/或频域的资源位置，网络设备利用所述指示信息中指示的资源位置，发送系统信息更新消息。
在一个可能的设计中，本申请的实施例提供一种处理系统消息的方法。所述处理系统消息的方法，包括用户终端获取指示信息，所述指示信息指示小区簇的系统消息发生改变，或者小区簇的系统消息是否发生改变，其中，所述小区簇包括至少一个小区的集合，所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他系统消息中的至少一个信息或者其组合；所述用户终端确定当前正在使用的小区簇信息是否需要更新。所述用户终端可以通过小区簇信息了解对应的系统信息是否需要更新。
所述指示信息可以由系统信息更新消息携带，也可以由系统消息携带。进一步地，用户终端可以根据所述指示信息，更新当前正在使用的小区簇信息或者当前正在使用的小区簇中小区的系统消息。这样，用户终端可以根据 小区簇信息更新对应的系统信息，及时有效地获取有用信息。若所述指示信息是通过系统消息携带的，则用户终端需要监听当前正在使用的小区簇信息所对应的系统消息。通过上述方式的不同设置可以更灵活地调度系统信息。
另一方面，本发明实施例提供多种网络设备，该网络设备具有实现上述方法实际中网络设备行为的功能。所述功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或软件包括一个或多个与上述功能相对应的模块。

具体实施方式
下面通过附图和实施例，对本发明的技术方案做进一步的详细描述。
为便于对本发明实施例的理解，下面将结合附图以具体实施例做进一步的解释说明，实施例并不构成对本发明实施例的限定。
本发明描述的技术可以适用于长期演进(long term evolution,简称LTE) 系统，或其他采用各种无线接入技术的无线通信系统，例如采用码分多址，频分多址，时分多址，正交频分多址，单载波频分多址等接入技术的系统。此外，还可以适用于使用LTE系统后续的演进系统，如第五代5G系统等。为清楚起见，这里仅以LTE系统为例进行说明。
如图1所示，LTE网络中，LTE系统信息广播(system information broadcast)是通信系统中的一个重要功能，其提供了接入网系统的主要信息，以便于UE建立无线连接。系统信息广播中的系统信息是连接UE和网络的纽带，UE与E-UTRAN之间通过系统信息的传递，完成无线通信各类业务和物理过程。
LTE系统信息广播中，下发对小区中所有UE配置都完全相同的信息，节省无线资源，使UE获得足够的接入信息、小区选择/重选的公共配置参数；还可以通知UE紧急信息：如地震海啸告警系统(ETWS)。通常，LTE系统消息广播的组成系统消息广播的内容被划分为多个系统信息块(system information blocks，SIB)，但是有一个“块”另外给起了个名字：主信息块(master information block，MIB)。因此系统广播信息就被划分为MIB和多个系统信息块(system information block)
随着网络发展，在浓密小区部署场景时，现有的系统消息的处理机制无法满足需求。
本发明的实施例提供一种新的实现机制，可以针对浓密小区的特点，有针对性的处理系统消息，避免现有技术的不足。
在一种可能的方式中，引入小区簇的概念。一个小区簇包括至少一个小区的集合。将多个小区划入一个小区簇，可以节约系统消息。
一、以下介绍小区簇的规定
为了说明本文的思想，以图2为例，其描述了一种较为简单的网络结构。F1是覆盖较大的范围，例如可以是宏小区。F2、F3……FN分别是不同的小区簇。每个小区簇包含至少一个小区。举例而言，小区簇1具有4个小区，可 以覆盖F2的范围，小区簇2具有3个小区可以覆盖F3的范围，以此类推。需要注意的是，不同小区簇所覆盖的范围可以相互交叠,相互重叠，或同覆盖。同覆盖，是指两个范围具有相同的覆盖区域。同一小区簇所包含的多个小区并不一定要相互邻接。不同小区簇的不同小区是可以邻接在一起的。总之，小区簇可以是具有相同属性的小区的集合，而不限定于地理位置。
小区簇的分类可以有多种方法。可以根据以下至少一个特征分类：
小区簇的小区所提供的业务类型信息；
小区簇的小区所支持的功能类型信息；
小区簇的小区的位置信息(比如在地域上相邻的小区)；
小区簇的小区的无线接入制式信息；
小区簇的小区的波束成形配置信息；
小区簇的小区的无线接入类型信息；
小区簇的小区的OFDM调制方式信息；
小区簇的小区的OFDM子载波组的信息。
以上特征仅是举例，而并不是限定于此。本领域技术人员可以理解，具有相同属性的小区可以分为一个小区簇。比如,小区簇一的小区都可以提供VoLTE(Voice over LTE)业务；小区簇二的小区都可以提供机器类通信(machine type communication,MTC),邻近服务(proximity-based service,ProSe)，即，基于蜂窝网络LTE的D2D通信(设备与设备通信)),车对车通讯技术(Vehicle-to-Vehicle,V2V)业务；小区簇三的小区都可以提供多媒体广播和组播服务(multimedia broadcast and multicast service，MBMS),单点对多点(single cell-point to multi-point,SC-PTM)业务。所以，如果小区簇的分类方法为小区簇的小区所提供的业务类型信息，则提供相同的业务类型的小区可以划分为一个小区簇。例如，业务类型可以为以下至少一个：MTC，MBB，Crucial MTC,home Enb,MBMS,ETWS/CMAS,Prose。
如果小区簇的分类方法为小区簇的小区所使用的OFDM调制方式信息，则 提供相同的OFDM调制方式的小区可以划分为一个小区簇,比如：小区簇一的小区都采用了快速傅立叶变换(fast fourier transformation，FFT)，其快速傅立叶变换点数(size)都是256点；而小区簇二的小区都采用的快速傅立叶变换点数(size)都是1024点。
如果小区簇的分类方法为小区簇的小区所使用的无线接入类型，则提供相同的无线接入类型的小区可以划分为一个小区簇,比如：小区簇一的小区都使用了相同的以下参数中的至少一种：每个子帧OFDM时间符号数目(OFDM symbols number per subframe),子帧长度(subframe duration),CP长度(CP length),CP的开销(CP overhead),HARQ的定时(HARQ timing))；CP Cyclic Prefix循环前缀。
或者若干个小区都采用了正交频分复用(orthogonal frequency division multiplexing，OFDM)技术。
或者若干个小区都使用了相同的无线接入制式：全球移动通讯系统(global system for mobile communications，GSM),通用移动通讯系统(universal mobile telecommunications system，UMTS),长期演进(long term evolution，LTE)或者下一代5G网络。
进一步，对小区簇进行分类时，分类的特性可以从多个维度进行，具有相同多个属性的小区可以分为一个小区簇。举例而言，业务类型也可以和其他特征绑定，例如，提供不同的业务类型的小区(e.g.MTC，MBB，Crucial MTC,home Enb,MBMS,ETWS/CMAS,Prose)可以有不同的无线接入类型，不同的OFDM方式，承载在不同的OFDM子载波组(OFDM sub-carrier grouping)上,或者具有不同的波束成型。
小区簇信息用于描述小区簇所具有的属性。这些属性来自小区簇所对应的小区的系统信息。小区簇信息可以包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他信息中的至少一个信息或者其组合。当小区簇仅包括一个小区时，该小区的属性可以作为该小区簇的小区簇信息。
小区簇的特征信息包含该小区簇中小区所具有的突出特性。举例而言，可以包括以下属性中的至少一个：
载波频率信息CarrierFreq，
带宽信息Bandwidth，
小区支持的业务和/或功能特性信息(可以是bitmap的格式),
无线接入类型信息，
波束成型配置信息，
随机接入信息(如果小区簇是随机接入资源是相同的)，
位置信息，
同步信息，
小区簇的小区的SIB块对应的专用的RNTI和小区簇的小区的专用的系统消息资源(可以从频率、时间、空间等维度来划分)。
这里解释一下小区支持的业务和/或功能特性信息。该信息可以是显示的定义，或者通过bitmap的格式来定义；
如，显示的定义：
service type：
VoLTE，MTC,Prose,V2V，MBMS，SC-PTM，VOIP,网真(Telepresence)…
如，bitmap的格式来定义:如，BIT STRING(0..20,…)
每个比特位置为1，则表明支持对应功能；0为不支持
VoLTE(第一比特位置)，MTC(第二比特位置),Prose(第三比特位置),V2V(第四比特位置)，MBMS(第五比特位置)，SC-PTM(第六比特位置)，VOIP(第七比特位置),网真(Telepresence)(第八比特位置)…如01100000：表明支持MTC,Prose业务。
这里解释一下，随机接入信息(如果小区簇是随机接入资源是相同的)。举例为随机接入的前导序列资源池(RA preamble)，PRACH(packet random access channel分组随机接入信道)的时频资源池。
这里解释一下同步信息。例如，该信息用于指示该小区簇中的小区之间是同步的，还是异步的；如果是同步，可以提供小区簇的绝对起始时间。
通常，小区簇中包含多个小区。每个小区的属性有很多，有相同的，也有不同的。小区簇的公共信息用来描述小区簇中小区的相同的属性。可以理解，小区簇的公共信息并不排斥小区簇的特征信息。即公共信息可以包含特征信息，也可以不包含特征信息。所述小区簇的公共信息可以包括以下至少一个信息：
公共陆地移动网络(public land mobile network，PLMN)标识(ID),
跟踪区编码(track area code，TAC),
全球小区识别码(cell global identifier，CGI)，
载波频率信息(carrierfreq)，
带宽信息(bandwidth)，
小区是否禁用的信息(cellbarred)。
小区簇接入信息用来描述小区簇中至少一个小区的接入信息。用户终端可以根据接入信息与小区建立连接或者驻留在该小区。本领域技术人员可以理解常规的用于接入信息都可以用作小区簇接入信息，在此不赘述，小区簇的接入信息可以包括以下至少一个信息：
公共陆地移动网络(public land mobile network，PLMN)标识(ID),
跟踪区编码(track area code，TAC),
全球小区识别码(cell global identifier，CGI)，
载波频率信息，
带宽信息，
随机接入信息，
工作模式信息(TDD or FDD),
小区的逻辑信道配置信息，
小区的物理信道和信令配置信息，
小区的信令配置信息，
定时器信息,
循环前缀(Cyclic Prefix,CP)长度,
功率控制信息。
小区的接入信息可以包括3GPP 36.331(3GPP TS 36.331 V13.0.0(2015-12)下载地址：http://www.3gpp.org/dynareport/36331.htm)中规定的MIB,SIB1或者/和SIB2所携带信息中的至少一部分信息，或者这三者所携带信息的至少部分信息的组合。该协议的内容都包含在本申请内，不再赘述。
可以理解，小区簇中的属性可以很多，我们还可以再设置一种小区簇的其他信息。小区簇的其他信息可以包括除小区簇的特征信息、公共信息、接入信息之外的小区簇的其他的信息。这些信息描述了小区簇的属性，和/或小区簇中小区的属性。
上述小区簇信息承载在系统消息里，可以通过以下至少一种方式发送所述带有小区簇信息的系统消息：广播，组播，专用信令。
小区簇的特征信息、公共信息、接入信息、其他信息可以同时出现，也可以只出现其中的某一个，也可以以组合的形式出现。同一属性也可以同时出现在上述信息中的一个或者多个。本发明并不限定。
小区簇还可以具有自己的标识信息，比如，索引号之类的信息。可以理解的，在系统消息内，该标识信息可以以显式的方式出现，即存在某个标识字段指示该小区簇信息是小区簇n的；也可以以隐式的方式出现，即没有某个标识特别指明该小区簇信息是小区簇n的(n为正整数)。虽然采用隐式的方式，但通信双方可以通过事先约定/通知，满足具体条件的小区簇信息是代表小区簇n的。比如在系统消息中的第n个信息单元就是小区簇n的小区簇信息。
二、以下介绍几种可能的小区簇信息的定义方式：
方式1)一个SIB中包含多个小区簇的小区簇信息。
表格1示出，在第M个SIB中，包含小区簇1到小区簇n的小区簇信息。可选的，每个小区簇信息中包含该小区簇的索引号。可选的每个小区簇信息中包含该小区簇信息的特征信息、公共信息、接入信息、其他信息中至少一个。通常，一个小区簇信息中至少要含有上述信息中的一个。以下各个表格中，SIB m仅代表这是第m个SIB，而不是说SIB中包含“SIB m”的文字。

SIB m

……
>>小区簇n的索引号(可选)
>>小区簇n的特征信息(可选)
>>小区簇n的公共信息(可选)
>>小区簇n的接入信息(可选)
>>小区簇1的其他信息(可选)
需要注意的是，此处表格的单元格仅是示例说明各个小区簇信息与SIB之间的关系，并不是用来限定为各个信息所占用的字段的长度，或者其他不合理的限定关系。并且即使上述特征信息、公共信息、接入信息、其他信息被定义在一个SIB当中，也可以对该SIB进行分段。所述分段可以以传输块大小为单位或以信息单元类型为单位。其中，信息单元类型为:特征信息、公共信息、接入信息或其他信息。本发明中即使一个SIB块的不同的分段的 调度周期的取值可以不同，举例说明：SIB m中的第一分段为特征信息，第二分段为公共信息，第三分段为接入信息，第四分段为其他信息，其中，第一分段的调度周期取值最小，第三分段的调度周期的次之，第二分段和第四分段的调度周期取值大于前两者并相同。
方式2)一个SIB包含一个小区簇信息，不同的SIB包含不同的小区簇信息。
表格2示出，SIB m包含小区簇1的小区簇信息。SIB z包含小区簇n的小区簇信息。可选的，每个小区簇信息中包含该小区簇的索引号。可选的每个小区簇信息中包含该小区簇信息的特征信息、公共信息、接入信息、其他信息。通常，一个小区簇信息中至少要含有上述信息中的一个。

因为小区簇信息的重要性不同，或者需求不同，可以对不同的SIB采取不同的调度周期。上述方式3)和方式4)中都可以对不同的SIB采取对应的调度周期。例如，可以让小区簇的特征信息的调度周期period_m较小，让小区簇的公共信息的调度周期period_n>period_m，同理，让小区簇的接入信息的调度周期period_x>period_m，以此类推。这样特征信息会被更频繁的更新，利于通信双方快速建立/维持通信。
以上表格1-4中的SIB代表一个系统信息块，通常会在一个常规的传输时间间隔，如TTI(1ms)内完成对SIB内容的单次发送。本发明的实施例同样适用于将SIB替换为其他时间单元或者其他信息单元的场景。
方式5)为方式4)的进一步变形。将小区簇信息按照方式4)那样定义。同时，在其他的信令，比如每个SIB、或者特定的SIB的头，通知小区簇信息的SIB的调度周期，比如SIB m的调度周期。当用户终端接收到调度周期和方式4)那样的系统消息时，就可以明确所对应的SIB。进而，可以选择监听该SIB的系统消息。这里所强调的小区簇信息的SIB是小区簇特征信息、公共信息、接入信息、其他信息中的一个。
在方式5)中，SIB需要包含小区簇信息的SIB的调度信息，其中调度信息包括以下信息中的至少一种：调度周期，小区簇信息的SIB的时域信息(无线帧，子帧，slot，和/或时间符号等信息)，小区簇信息的SIB的频域信息(发送带宽，PRB序号，和/或PRB位置等信息)。
举例，在方式5)中，所述小区簇1的特征信息可以包括：如支持的业务和/或功能特性信息(支持CA载波聚合(carrier aggregation，简称CA), 双连接(dual connectivity，DC),多天线(multiple input multiple output，MIMO)功能，支持Prose业务),载波频率信息CarrierFreq，带宽信息Bandwidth，无线接入类型：type 2，波束成型配置，位置信息，同步信息(如果小区簇是同步部署的)。小区簇n的特征信息可以包括：如支持的业务或功能特性信息(支持协作多点传输(coordinated multi-point transmission，CoMP,DC功能，支持MTC,MBMS,V2V业务),载波频率信息CarrierFreq，带宽信息Bandwidth，无线接入类型：type 4，波束成型配置，资源位置(周期,偏移量,OFDM子载波组(OFDM sub-carrier grouping)),随机接入信息(如果小区簇是随机接入资源是相同的)，位置信息,对应的RNTI。
通信双方可以遵守上述小区簇的规定，以及小区簇信息的定义方式1)-方式5)，通常是网络设备和用户终端。网络设备，指与用户进行通信的网络设备。例如，网络设备可以是基站，包括宏基站，微小区基站，家庭基站等，也可以是实现中继功能的基站，或者类似的设备。用户终端，指向用户提供语音和/或数据连通性的设备(device)，包括无线终端或有线终端。无线终端可以是具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。例如，无线终端可以是移动电话(或称为“蜂窝”电话)和具有移动终端的计算机。又如，无线终端也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。再如，无线终端可以为移动站(英文为：mobile station)、或用户设备(英文为：user equipment，简称UE)的一部分。
实施例一
参照图3，网络设备按照方式1)-方式5)中的一种，发送带有至少一个小区簇信息的系统消息。通常，网络设备可以使用广播的方式发送，也可以采用组播的方式发送，也可以使用专用信令发送，但是本发明并不限于此。
本发明可以支持多小区的广播传输模式，组播方式的一种。即使用多播/ 组播单频网络(multimedia broadcast multicast service single frequency network，MBSFN)的方式，发送相同的带有小区簇信息的系统消息。至少一个小区簇对应的基站设备同时发送相同的带有小区簇信息的系统消息，允许用户同时接收多小区发送的信号进行合并处理以提高传输性能。这种情况下，若想避免符号间干扰(intersymbol interference，ISI)，则要求多个小区发送的信号的时延不能超过CP的长度。
本发明可以支持以专用信令的方式发送系统消息。所述网络设备或小区簇对应的基站设备根据特定用户的需求，发送和这个用户相关的带有小区簇信息的系统消息，并通过专用RRC信令发送给该用户，如RRC重配消息，RRC释放消息。如通过RRC释放消息发送带有小区簇信息的系统消息。本领域技术人员可以了解在上述专用信令中设置字段的方法，不再赘述。
对应的，用户终端按照与网络设备对应的处理方式，接收带有至少一个小区簇信息的系统消息，进而从该系统消息中获得所需的信息，进行进一步的处理。这种处理可以是选择一个小区。
因为采用了小区簇的概念，即在系统消息内携带了小区簇信息，通过小区簇信息，网络设备可以将重要的信息发送出来，用户终端可以获得所需信息，所以网络设备和用户终端可以应对多层小区结构所带来的挑战。
实施例二
本实施例描述网络设备。
如图4，一种网络设备，包括：
处理单元401，用于确定带有至少一个小区簇信息的系统消息，所述小区簇包括至少一个小区的集合；所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他系统消息信息中的至少一个信息或者其组合；
发送单元402，用于发送所述带有小区簇信息的系统消息。
所述小区簇还可以包括至少两个小区的集合，这样可以满足多小区场景的需求。
进一步的，上述发送单元用于通过以下至少一种方式发送所述带有小区簇信息的系统消息，广播、组播、专用信令。
本实施例的网络设备，其处理单元可以采用上文中小区簇的规定，以及小区簇信息的定义方式，在此不再赘述。其发送单元可以遵照上文中小区簇的规定，以及小区簇信息的定义方式发送系统消息。本实施例的网络设备可以使用第四实施例的方法。
本实施例的网络设备具备以下优点：可以按需调度具有小区簇信息的系统消息进行发送；也丰富了调度的灵活性，使得根据业务划分小区簇及其对应的无线资源成为可能。
作为一种示例，图5示出了网络设备及其所属的网络结构。网络设备100向其覆盖的F1范围发送上述系统消息，通常以广播的方式。若干个基站设备200为小区簇1的基站，若干个基站设备300为小区簇2的基站。一个基站可以对应多个小区，这里用基站/小区200指代小区簇内的对应的小区，而不限定于基站本身。所述网络设备100可以是与基站设备200/300同覆盖或相邻的网络节点。UE 1位于小区簇1中的一个基站设备200所覆盖的小区内。UE 1同样可以接收到网络设备100所发送的系统消息。可以理解，只要F1范围和F2范围有交叠，UE 1就可以收到网络设备100所发送的系统消息。需要注意的是，网络设备100所发送的系统消息带有小区簇信息。这里所携带的小区簇信息包含了小区簇1的小区簇信息，即小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他系统消息中的至少一个信息或者其组合。实际上,UE 1通过网络设备100的系统消息500，收到了基站/小区200的相关系统信息。可以看出基站/小区200的系统信息，以小区簇信息的形式通过系统消息500进行了发送。即，第一网络设备100发送了至少一个第二网络设备200的系统信息，即第一网络设备100通过其系统消息发送了至少 一个第二网络设备的属性。
更可以看出本发明的优点之一在于，将小区簇信息进行了精简，从而节省了系统消息500的大小，使得在网络设备100的层面可以对多个小区簇进行统筹的管理。
进一步的，倘若所述系统消息500还包含小区簇2的小区簇信息，则UE 1可以获知基站/小区300的系统信息。若UE 1位于小区簇1所对应的范围F2，且位于小区簇2所对应的范围F3,则UE 1可以更快捷地了解到这两个小区簇中的哪个小区更适合自己的业务需求，从而进行快速的响应。
如上文所述，小区簇信息中可以包含小区簇的接入信息。该接入信息描述了小区簇中至少一个小区的接入信息。可以理解，当该接入信息包括了某一小区的足够的接入信息时，用户终端可以仅凭小区簇的接入信息就可以建立/维持与对应小区的通信或者驻留在对应的小区。当该接入信息仅包括了某一小区的部分接入信息时，用户终端不可以仅凭小区簇的接入信息建立/维持与对应小区的通信或者驻留在对应的小区，则用户终端可以采取进一步的措施。这些措施包括而不限于：用户终端触发询问机制，通过特定的信令来从小区对应网络设备(如网络设备100，或者基站/小区200)获取其他接入信息；用户终端在除系统消息500之外的其他系统消息上监听，获取其他接入信息。小区簇的一个小区的接入信息或者其他信息也不一定全部通过小区簇信息发送，而可以由该小区自己对应的网络节点，如基站，发送。所以，小区簇的接入信息的一个小区的接入信息的一部分和/或小区簇的系统消息的一个小区的系统消息还可以由所述小区对应的网络节点自己发送。
可选的，所述基站设备200或300也可以发送网络设备200和300对应的小区簇1和小区簇2的信息。
虽然图5中示出的是两层小区的结构，但是本发明并不限定于此。本领域技术人员可以理解，相同的技术方案也可以应用于三层以上小区的结构，或者小区直接存在交叠的情况。
可选的，在发送过程中，有可能因为SIB中包含的小区簇信息较多，而出现SIB的长度大于常规的传输时间间隔，如TTI，的最大尺度的情况，则可以将该SIB在一个发送窗内被分段发送。在一个SI(system information)中可以包含多个周期相同的SIB，具体的映射关系配置包含在SIB1的调度信息中。即，某个SIB块会根据对应的SI,每隔一个调度周期会有一个广播窗，并在广播窗内重复广播该SI中的SIB内容。举例而言，每个SI的发送窗的起始位置，由以下公式确定：
具体的算法是：
x＝(n-1)*Window Length其中n是指SI-n中的n，是索引，n大于等于1。
确定了x后，UE需要确定SI-n起始的无线帧和子帧位置，具体的算法是：
子帧位置：a＝x mod 10
无线帧位置：SFN mod T＝FLOOR(x/10)
其中Window Length是一个绝对的数值，取值范围是[1,2,5,10,15,20,40]，单位是子帧，并在SIB1中指示。
而本发明提供一种技术，即如果该SIB承载的信息内容的长度大于常规的传输时间间隔(如TTI)的最大传输块尺度时，将该SIB承载的信息内容分段，如分成segment_1，segment_2，然后在发送窗内按序反复发送：segment_1，segment_2，segment_1，segment_2…,其中，可以在每个分段内在指示信息，表明本SIB内容未结束或是已结束，UE需要继续读取。指示信息可以在RRC信令内添加，也可以通过MAC SDU/PDU指示。
第三实施例
对应于第二实施例的网络设备，本实施例还提供一种用户终端。
如图6，一种用户终端，包括：
接收单元601，用于接收所述带有至少一个小区簇信息的系统消息，所述 小区簇包括由至少一个小区构成的集合；所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他系统消息中的至少一个信息或者其组合；
处理单元602，根据所述系统消息选择至少一个小区，所选择的小区是上述小区簇信息中所指示的小区。
本实施例的用户终端，可以遵从或者采用上文中小区簇的规定，以及小区簇信息的定义方式，在此不再赘述。本实施例的用户终端可以使用第五实施例的方法。可以理解本实施例与第二实施例的网络设备是对应的，所以，相同或者类似的部分不再赘述。
本实施例的用户终端具备以下优点：可以调度具有小区簇信息的系统消息；也丰富了调度的灵活性，使得根据业务划分小区簇及其对应的无线资源成为可能。本实施例的用户终端还可以避免不必要的读取系统消息的工作量。
可选的，用户终端可以根据所述系统消息中的小区簇选定具体的小区，也可以在选定具体小区之前，先选定小区簇，再结合小区簇中各个小区中的其他信息来确定需要使用的小区。举例而言，用户终端可以先选定小区簇2，比如小区簇2具有低时延的特性，再根据小区簇2中对应的小区a、小区b或小区c的情况，选定使用小区c。各个小区的情况，可以采用常规的技术手段，比如无线条件、地理位置等信息。例如，可以使用参考信号接收功率(reference signal received power，RSRP)/参考信号接收质量(reference signal received quality,RSRQ)等信息作为参考手段。用户终端可以选择里自己近的，信道条件好的小区。
可选的，用户终端在选择好自己需要的小区之后，还可以选择进一步与小区建立通信或者驻留到该小区。这时，用户终端就需要获取该小区的接入信息。类似于实施例二中关于小区簇信息的接入信息的描述，用户终端可以触发询问机制，来获取必要的接入信息，也可以根据小区簇信息中的接入信息来获得必要的接入信息。这些接入信息包括而不限于，小区选择/重选信息， GPS信息，CDMA2000信息，WLAN和LTE聚合的信息，MBMS的信息。
第四实施例
类似于第二实施例的网络设备，本实施例还提供一种发送系统消息的方法。图7示出该方法，包括：
701、网络设备确定带有至少一个小区簇信息的系统消息，所述小区簇包括至少一个小区的集合；所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他信息中的至少一个信息或者其组合；
702、所述网络设备发送所述带有小区簇信息的系统消息。
本实施例的方法可以遵照可以采用上文中小区簇的规定，以及小区簇信息的定义方式，在此不再赘述。本实施例的方法可以由第二实施例的网络设备使用，并获得类似的优点。
可选的，所述网络设备发送所述带有小区簇信息的系统消息，包括：所述网络设备通过以下至少一种方式发送所述带有小区簇信息的系统消息：广播，组播，专用信令。
可选的所述小区的接入信息包括主信息块(master information block，MIB),SIB1或者SIB2所携带信息中的至少部分信息。
可选的，所述小区簇信息的小区对应的网络节点与所述网络设备有相同的覆盖区域，或该网络节点与所述网络设备相邻。所述网络设备也可以是所述小区簇信息的一个或多个小区对应的网络节点。可以看出本实施例的网络设备可以是并不限定于大覆盖范围的网络节点，只要可以发送包含小区簇信息的系统信息的网络节点都可以是所述网络设备。当应用于不同场景时，会具有对应的优点和效果。
当所述网络设备是所述小区簇信息的一个或多个小区对应的网络节点时，所述网络设备发送所述小区簇的接入信息的一个小区的接入信息的一部 分，也可以发送小区簇的其他信息的一个小区的系统消息的一部分。这里小区的的接入信息可以是小区簇的接入信息的一部分，或者是相同的信息。小区簇的其他信息和小区的系统消息也是类似。只要所发送的信息是用户终端接入时需要的信息即可。
可选的，当包含小区簇信息的SIB的长度大于一个TTI内的发送的最大尺度，该SIB在一个发送窗内被分段发送。
可选的，网络设备发送带有小区簇信息的系统消息，包括：网络设备是至少一个小区簇的中心控制节点相关的网络节点多个网络设备，通过多播/组播单频网络(multimedia broadcast multicast service single frequency network,MBSFN)的方式发送带有小区簇信息的系统消息。
第五实施例
类似于第三实施例的用户终端，本实施例还提供一种接收系统消息的方法。图8示出一种接收系统消息的方法，包括：
801、用户终端接收带有至少一个小区簇信息的系统消息，所述小区簇包括由至少一个小区构成的集合，所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他系统消息中的至少一个信息或者其组合；
802、所述用户终端根据所述系统消息选择至少一个小区，所选择的小区是上述小区簇信息中所指示的小区。
本实施例的方法可以遵照可以采用上文中小区簇的规定，以及小区簇信息的定义方式，在此不再赘述。本实施例的方法可以由第三实施例的用户终端使用，并获得类似的优点。可以理解本实施例与第三实施例是对应的，所以，相同或者类似的部分不再赘述。
本实施例的方法具备以下优点：可以调度具有小区簇信息的系统消息；也丰富了调度的灵活性，使得根据业务划分小区簇及其对应的无线资源成为 可能。本实施例的方法还可以避免不必要的读取系统消息的工作量。
可选的，所述用户终端可以根据所述小区簇的特征信息选择一个小区簇，选择至少一个小区，所选择的至少一个小区是所述小区簇中的小区。
可选的，所述用户终端根据所述系统消息选择至少一个小区，包括：所述用户终端根据所选择的小区，获取该小区的接入信息。
可选的，所述用户终端根据所选择的小区，获取该小区的接入信息，包括：用户终端从所选择的小区获取接入信息，所述接入信息包含所选择的小区的接入信息。可选的，所述用户终端根据所选择的小区，获取该小区的接入信息，包括：用户终端从所述小区簇信息中的小区簇的接入信息，获取所选择的小区的接入信息。
以上介绍了使用小区簇信息的系统消息的发送和接收设备及其方法。以下介绍根据处理小区簇信息的系统消息的发送和接收设备及其方法。
实施例六
参照图9，通信双方遵守上述小区簇的规定，以及小区簇信息的定义方式1)-方式5)。会存在需要更新系统信息的情况。通常，可以采用至少以下几种系统消息变更的通知方式：1.网络侧使用带有通知的指示消息来通知用户终端系统信息的改变，用户终端在下一个修改周期开始监听新的系统消息；2.在系统消息中携带标签信息，用户终端读取标签，若标签发生变化，则表明系统信息已经发生变化，用户终端需要重新读取系统消息；3.已经获得的系统消息存在有效期，当有效期到期时，用户终端需要重新读取系统消息。
需要注意的是，本实施例的系统消息带有小区簇信息。对应的网络侧和用户侧的处理存在明显的特点，即，需要根据小区簇中小区簇信息来提供不同的处理。因为小区簇的网络结构不同，所以更新对应的系统消息的方式也不同。1.网络侧的带有通知的指示消息可以仅携带当前用户终端所需的小区簇的系统信息，用户终端可以对应接收该指示消息；或者网络侧的指示消息 依旧指示至少一个小区簇的系统信息是否发生变化，用户终端仅接收这些指示消息中的一个或者一部分，所接受的指示消息或者该信息的一部分指示当前所需的小区簇的系统信息是否发生变化。2.网络侧的标签信息指示至少一个小区簇的系统信息发生变化，用户终端读取该标签信息，若发现所指示的发生系统信息变化的小区簇/小区正是该用户终端所需的小区簇中的小区，则重新读取系统消息；3.用户终端确定已经获得的系统消息的有效期到期时，用户终端根据当前所使用的小区簇的规定和/或小区簇信息的定义方式，重新读取所需小区簇信息所携带的系统信息。
对应的，用户终端按照与网络设备对应的处理方式，接收带有至少一个小区簇信息的系统消息，进而从该系统消息中获得所需的数据，进行进一步的处理。虽然用户终端通常接入一个小区，但是本实施例还包括用户终端同时接入多个小区，或者准备接入多个小区的情况。多个小区可以来自多个小区簇，也可以来自一个小区簇。所以，上述用户终端所需的小区簇或小区包括用户终端当前正在使用的小区簇或小区，也包括用户终端准备使用的小区簇或小区。
因为采用了小区簇的概念，即在系统消息内携带了小区簇信息，通过小区簇信息，网络设备可以将需要更新的信息发送出来，用户终端可以获得更新所需数据，所以网络设备和用户终端可以应对多层小区结构所带来的挑战。
实施例七
本实施例描述网络设备。
图10示出一种网络设备，包括
处理单元1002，用于确定需要更新的系统信息对应的小区簇，所述小区簇包括至少一个小区的集合，所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他信息中的至少一个信息或者其组合；
发送单元1001，用于发送指示信息，所述指示信息指示小区簇的系统消 息发生改变，或者小区簇的系统消息是否发生改变。
本实施例的网络设备，其处理单元可以采用上文中小区簇的规定，以及小区簇信息的定义方式，在此不再赘述。其发送单元可以遵照上文中小区簇的规定，以及小区簇信息的定义方式发送指示信息。本实施例的网络设备可以使用第九实施例的方法。
本实施例的网络设备具备以下优点：可以调度具有小区簇信息的系统消息；也丰富了调度的灵活性，使得根据业务划分小区簇及其对应的无线资源成为可能。
这里的小区簇的系统消息指与该小区簇有关的信息，包括而不限于，小区簇信息，小区簇的小区的系统信息。当通信双方规定上述指示信息的含义是小区簇的系统消息发生改变时，这意味着，当出现该指示信息时，小区簇的系统消息就发生改变，当未出现该指示信息时，小区簇的系统消息就没有发生改变。当通信双方规定上述指示信息的含义是小区簇的系统消息是否发生改变时，这意味着，该指示信息的值对应小区簇的系统消息的状态。当该指示信息的值为第一值时，比如1，小区簇的系统消息就发生改变，当该指示信息的值为第二值时，比如0，小区簇的系统消息就没有发生改变；或者当该指示信息的值和上次用户设备获取的指示信息的值不同时，小区簇的系统消息就发生改变，当该指示信息的值和上次用户设备获取的指示信息的值相同时，小区簇的系统消息就没有发生改变。
可选的，还可以使用类似的方式指示小区簇中的小区的系统消息发生改变，或者小区簇中的小区的系统消息是否发生改变。这里的小区并不限定个数，可以是多个，只要通信双方约定好，或者以其他方式知晓指示信息所代表的含义即可。必要的话双方可以预存一个表格，保留对应的映射关系。若选择指示信息，指示小区簇的小区的系统信息，则该指示信息可以不再指示小区簇的系统信息，也可以选择另外的指示信息指示小区簇的系统信息。
作为一种特例，类似于上文中的隐式指示小区簇的标识信息，隐式的指 示信息也包含在本实施例中，即通信双方约定，满足特定条件的未出现的指示信息，可以指示小区簇或者小区的系统消息发生改变。
可选的，所述指示信息可以由系统消息携带。如在系统消息的MIB，或某个SIB。所述指示信息也可以用系统信息更新消息携带。所述系统信息更新消息可以是传统的寻呼(paging)消息、RRC消息或者MAC信令，也可以是通过物理控制信道、同步信道发送的信令。所述指示信息可以是上述信令中的某一个字段或者单元。这意味着采用了除系统消息之外的别的信息来完成。
可选的，为了完成指示的功能，网络设备发送的指示信息，还可以包括：网络设备配置的小区簇的索引号，所述网络设备在发送的用于调度系统信息更新消息的物理控制信道(如，下行物理控制信道,physical downlink control channel,PDCCH)中携带所述指示信息,比如，网络设备通过RRC消息配置小区簇1的索引号为0，小区簇2的索引号为1，小区簇3的索引号为2，小区簇4的索引号为3，在PDCCH的对应指示域中，如果是比特位00，则表明是小区簇1的系统消息发生改变，如果是11，则表明是小区簇4的系统消息发生改变，该指示域可以指示多个小区簇。
可选的，指示信息可以是网络设备配置的小区簇对应的网络临时标识(radio network temporary identifier，RNTI)，网络设备在发送的用于调度系统信息更新消息的物理控制信道时用所述指示信息做循环冗余校验(cyclic redundancy check,CRC)操作；
可选的，指示信息是网络设备配置的小区簇对应的信道配置参数，比如解调参考信号(demodulation reference signal，DM-RS),信道状态信息参考信号(channel status information reference signal，CSI-RS),扰码序列索引(scrambling sequence index，SCID)，网络设备利用所述指示信息中信道配置参数，配置系统信息更新消息的物理控制/数据信道；
可选的，指示信息是网络设备发送小区簇对应的系统更新消息的时域和/或频域的资源位置，或者是计算小区簇对应的系统更新消息的时域和/或频域 的资源位置所需的参数，如UE的非连续接收(discontinuous reception，DRX)周期，UE_ID,小区簇ID。比如，用于指示系统更新的寻呼消息的时域位置的PF/PO。网络设备利用所述指示信息中指示的资源位置，发送系统信息更新消息。其中，寻呼帧PF(paging frame)是一个无线帧，其中可能包含一个或者多个寻呼时机PO(paging occasion)。PO是一个子帧。UE在一个寻呼周期内只需检测一个PO。也就是说，对于某个UE，PF就是用来发送Paging消息的无线帧，PO就是该PF内用于发送Paging消息的子帧。举例如下：
1)网络设备直接配置网络设备发送小区簇对应的系统更新消息的时域和/或频域的资源位置，如，小区簇1的PF1,PO1的取值范围，小区簇2的PF2,PO2的取值范围…；或者：
2)用户设备根据UE的DRX周期，UE_ID,小区簇ID等参数推导出网络设备发送小区簇对应的系统更新消息所发送时域和/或频域的资源位置：推导方法，举例说明，以下方法是在PO，即，子帧的划分上区分网络设备发送小区簇对应的系统更新消息的不同时域位置：
PF是满足如下公式的无线帧：
SFN mod T＝(T div N)*(UE_ID mod N)
PO(对于FDD来说)由下表查表可知
Ns PO when i_s＝0 PO when i_s＝1 PO when i_s＝2
1 9 N/A N/A
2 4 9 N/A
4 0 4 5
Index i_s：i_s＝(floor(UE_ID/N)mod Ns)mod小区簇_ID
i_s是索引，用于查表；N是中间变量，可以为min(T,nB)；Ns为中间变量，可以为max(1,nB/T)；SFN是系统帧号System Frame Number；T为UE的DRX周期，取高层给UE分配的DRX周期值与网络设备配置的默认的DRX值的最小值。nB可以为4T,2T,T,T/2,T/4,T/8,T/16,T/32。UE_ID可以为IMSI mod 1024。mod为取模，div为整除。
或者：推导方法，举例说明，以下方法是在PF，即，无线帧的划分上区分网络设备发送小区簇对应的系统更新消息的不同时域位置：
如小区簇ID从1开始，如小区簇1，小区簇2，小区簇3，小区簇4，PF是满足如下公式的无线帧：
(SFN–T2*(小区簇_ID-1))mod T2＝(T2 div N2)*(UE_ID mod N2)
T2＝T div(小区簇数)
N2＝min(T2,nB)
PO(对于FDD来说)由下表查表可知
Ns PO when i_s＝0 PO when i_s＝1 PO when i_s＝2
1 9 N/A N/A
2 4 9 N/A
4 0 4 5
Index i_s：i_s＝(floor(UE_ID/N)mod Ns)mod小区簇_ID
i_s是索引，用于查表；N是中间变量，可以为min(T,nB)；Ns为中间变量，可以为max(1,nB/T)；SFN是系统帧号System Frame Number；T为UE的DRX周期，取高层给UE分配的DRX周期值与网络设备配置的默认的DRX值的最小值。nB可以为4T,2T,T,T/2,T/4,T/8,T/16,T/32。UE_ID可以为IMSI mod 1024。mod为取模，div为整除。
以上，仅列举了一些指示信息的形式，本领域人员可以理解指示信息并不限于此，只要可以完成指示小区簇的系统消息发生改变，或者小区簇的系统消息是否发生改变的功能，或者完成指示小区簇中的小区的系统消息发生改变，或者小区簇中的小区的系统消息是否发生改变的功能，都可以实现本实施例的方案。

对应于实施例七，本实施例描述用户终端。
图11示出一种用户终端，包括
获取单元1101，用于获取指示信息，所述指示信息指示小区簇的系统消息发生改变，或者小区簇的系统消息是否发生改变，其中，所述小区簇包括至少一个小区的集合，所述小区簇信息包括小区簇的特征信息、小区簇的公共信息、小区簇的接入信息、小区簇的其他系统消息中的至少一个信息或者其组合；
处理单元1102，用于确定当前使用的小区簇信息是否需要更新。
本实施例的用户终端，其处理单元可以采用上文中小区簇的规定，以及小区簇信息的定义方式，在此不再赘述。其获取单元可以遵照上文中小区簇的规定，以及小区簇信息的定义方式获取指示信息。本实施例的用户终端可以使用第十实施例的方法。
这里的获取单元可以是接收单元，用于接收所述指示信息，也可以是处理单元本身，用于确定所述指示信息。所述处理单元可以通过预先约定确定所述指示信息。作为一种特例，类似于上文中的隐式指示小区簇的标识信息，隐式的指示信息也包含在本实施例中，即通信双方约定，满足特定条件的未出现的指示信息，可以指示小区簇或者小区的系统消息发生改变。
本实施例的用户终端具备以下优点：可以获取具有小区簇信息的系统消息进行更新；也丰富了调度的灵活性，使得根据业务划分小区簇及其对应的无线资源成为可能。
这里的小区簇的系统消息指与该小区簇有关的信息，包括而不限于，小区簇信息，小区簇的小区的系统信息，类似于实施例七，不再赘述。可选的，还可以使用类似的方式指示小区簇中的小区的系统消息发生改变，或者小区簇中的小区的系统消息是否发生改变。
可选的，所述指示信息由系统信息更新消息携带，
所述用户终端获取指示信息，包括：所述用户终端获取所述系统信息更 新消息，其中所述系统信息更新消息是寻呼消息或者一种RRC消息、MAC信令或者通过物理控制信道、同步信道发送的信令；所述用户终端确定当前正在使用的小区簇信息是否需要更新，包括：所述用户终端根据所述系统信息更新消息中的指示信息，更新当前正在使用的小区簇信息，和/或所述用户终端根据所述系统信息更新消息中的指示信息，更新当前正在使用的小区簇中小区的系统消息。
可选的，所述指示信息由系统消息携带，
所述用户终端获取指示信息，包括：所述用户终端获取所述系统消息，所述系统消息指示当前正在使用的小区簇；用户终端根据所述指示信息，确定当前正在使用的小区簇信息是否需要更新，包括：所述用户终端根据所述系统消息中的指示信息，更新当前正在使用的小区簇信息，和/或所述用户终端根据所述系统消息中的指示信息，更新当前正在使用的小区簇中小区的系统消息。
以系统消息携带指示信息为例，用户终端当前使用的是小区簇2，特性是载波频率为频段1。如用户在读取系统消息时，发现在系统消息的MIB，或某个SIB中指示小区簇2的系统消息发生了改变，则用户确定需要更新小区簇2时并获取系统消息中针对小区簇2的部分。将对应于小区簇2的部分重新读取并更新即可。这样就不需要读取太多的系统消息，即可快速的更新所需要的系统消息。
以系统信息更新消息携带指示信息为例，用户终端当前使用的是小区簇2，特性是载波频率为频段1。如用户在接收到系统信息更新消息时，发现系统信息更新消息中指示小区簇2的系统消息发生了改变，则用户确定需要更新小区簇2时并获取系统消息中针对小区簇2的部分。将对应于小区簇2的部分重新读取并更新即可。这样就不需要读取太多的系统消息，即可快速的更新所需要的系统消息。
可选的，所述用户终端获取所述系统消息，包括：所述用户终端监听当 前正在使用的小区簇信息所对应的系统消息。
可以理解的，所述当前正在使用的小区簇信息还可以包括即将使用还未使用的小区簇信息。这种场景是，用户终端已经建立了与某小区的通信，用户终端还需要建立于其他小区的联系。所以，需要进一步更新那些可能使用但是还未使用的小区簇信息。所述技术方案中，仅需要将小区簇信息的内容进行调整即可，其他技术细节参见各个实施例的具体方案。这样丰富了用户终端的灵活性，可以根据需要灵活的选择需要的小区簇信息。
可选的，用户终端根据所述指示信息，更新当前使用的小区簇信息。当指示信息指示当前使用的小区簇信息需要更新时，用户终端触发更新过程。当指示信息指示当前使用的小区簇信息不需要更新时，用户终端不触发更新过程。
作为一种可能的方式，用户终端可以跳过所谓的“确定”过程，即确定当前正在使用的小区簇信息是否需要更新，直接进行更新过程。因为用户终端触发更新，可以被认为是所谓的“确定”过程的一种。
可选的，所述用户终端确定当前正在使用的小区簇信息是否需要更新，还包括：
所述指示信息是接收到的网络设备配置的小区簇的索引号，
所述用户终端读取接收到的用于调度系统信息更新消息的物理控制信道(如，PDCCH)中携带所述指示信息,比如，用户终端之前接收到网络设备通过RRC消息配置小区簇1的索引号为0，小区簇2的索引号为1，小区簇3的索引号为2，小区簇4的索引号为3；如果用户终端当前使用的是小区簇1，在读取PDCCH中对应指示域时，如果指示域中的比特位是00，则用户终端认为是小区簇1的系统消息发生改变，便去读取和更新当前正在使用的小区簇1的信息；如果是11，则用户终端认为是小区簇4的系统消息发生改变，用户终端不触发更新过程；另外该指示域可以指示多个小区簇。
可选的，所述用户终端确定当前正在使用的小区簇信息是否需要更新，还包括：
指示信息是接收到的网络设备配置的小区簇对应的网络临时标识(Radio Network Temporary Identifier，RNTI)，
所述用户终端通过所述指示信息对用于调度系统信息更新消息的物理控制信道时用做CRC操作；比如，用户终端之前接收到网络设备通过RRC消息配置小区簇1的RNTI为P1-RNTI，小区簇2的RNTI为P2-RNTI，小区簇3的RNTI为P3-RNTI，小区簇4的RNTI为P4-RNTI；如果用户终端当前使用的是小区簇1，则用P1-RNTI对PDCCH进行CRC操作，如果成功，则用户终端认为是小区簇1的系统消息发生改变，便去读取和更新当前正在使用的小区簇1的信息；如果不成功，则用户终端认为是小区簇1的系统消息没有发生改变，用户终端不触发更新过程；如果用户终端当前使用的是小区簇1和小区簇4，则UE可以分别用P1-RNTI，P4-RNTI对PDCCH进行CRC操作。
可选的，所述用户终端确定当前正在使用的小区簇信息是否需要更新，还包括：
指示信息是接收到的网络设备配置的小区簇对应的信道配置参数，比如解调参考信号(demodulation reference signal，DM-RS),信道状态信息参考信号(Channel Status Information reference signal，CSI-RS),扰码序列索引(scrambling sequence index，SCID)，所述用户终端利用所述指示信息中信道配置参数读取系统信息更新消息的物理控制/数据信道；比如，用户终端之前接收到网络设备通过RRC消息配置小区簇的信道配置参数，如果用户终端当前使用的是小区簇1，则用小区簇1的信道配置参数去解读系统信息更新消息的物理控制/数据信道，如果成功，则用户终端认为是小区簇1的系统消息发生改变，便去读取和更新当前正在使用的小区簇1的信息；如果不成功，则用户终端认为是小区簇1的系统消息没有发生改变，用户终端不触发更新过程。
可选的，所述用户终端确定当前正在使用的小区簇信息是否需要更新，还包括：
指示信息是用户终端接收小区簇对应的系统更新消息的时域和/或频域的资源位置，或者是计算小区簇对应的系统更新消息所发送的时域和/或频域的资源位置所需的参数，如UE的DRX周期，UE_ID,小区簇ID。比如，用于指示系统更新的寻呼消息的时域位置的PF/PO。用户终端利用所述指示信息中指示的资源位置，接收系统信息更新消息。其中，寻呼帧PF(paging frame)是一个无线帧，其中可能包含一个或者多个寻呼时机PO(paging occasion)。PO是一个子帧。用户终端在一个寻呼周期内只需检测一个PO。也就是说，对于某个用户终端，PF就是用来发送Paging消息的无线帧，PO就是该PF内用于发送Paging消息的子帧。举例如下：
1)用户终端接收网络设备直接配置网络设备发送小区簇对应的系统更新消息的时域和/或频域的资源位置，如，小区簇1的PF1,PO1的取值范围，小区簇2的PF2,PO2的取值范围…；或者：
2)用户设备根据UE的DRX周期，UE_ID,小区簇ID等参数推导出网络设备发送小区簇对应的系统更新消息所发送时域和/或频域的资源位置：推导方法，举例说明，以下方法是在PO，即，子帧的划分上区分网络设备发送小区簇对应的系统更新消息的不同时域位置：
PF是满足如下公式的无线帧：
SFN mod T＝(T div N)*(UE_ID mod N)
PO(对于FDD来说)由下表查表可知
Ns PO when i_s＝0 PO when i_s＝1 PO when i_s＝2
1 9 N/A N/A
2 4 9 N/A
4 0 4 5
Index i_s：i_s＝(floor(UE_ID/N)mod Ns)mod小区簇_ID
i_s是索引，用于查表；N是中间变量，可以为min(T,nB)；Ns为中间 变量，可以为max(1,nB/T)；SFN是系统帧号System Frame Number；T为UE的DRX周期，取高层给UE分配的DRX周期值与网络设备配置的默认的DRX值的最小值。nB可以为4T,2T,T,T/2,T/4,T/8,T/16,T/32。UE_ID可以为IMSI mod 1024。mod为取模，div为整除。
或者：推导方法，举例说明，以下方法是在PF，即，无线帧的划分上区分网络设备发送小区簇对应的系统更新消息的不同时域位置：
如小区簇ID从1开始，如小区簇1，小区簇2，小区簇3，小区簇4，PF是满足如下公式的无线帧：
(SFN–T2*(小区簇_ID-1))mod T2＝(T2 div N2)*(UE_ID mod N2)
T2＝T div(小区簇数)
N2＝min(T2,nB)
PO(对于FDD来说)由下表查表可知
Ns PO when i_s＝0 PO when i_s＝1 PO when i_s＝2
1 9 N/A N/A
2 4 9 N/A
4 0 4 5
Index i_s：i_s＝(floor(UE_ID/N)mod Ns)mod小区簇_ID
i_s是索引，用于查表；N是中间变量，可以为min(T,nB)；Ns为中间变量，可以为max(1,nB/T)；SFN是系统帧号System Frame Number；T为UE的DRX周期，取高层给UE分配的DRX周期值与网络设备配置的默认的DRX值的最小值。nB可以为4T,2T,T,T/2,T/4,T/8,T/16,T/32。UE_ID可以为IMSI mod 1024。mod为取模，div为整除。
。
所述用户终端利用所述指示信息中指示的资源位置，接收系统信息更新消息；比如，如果用户终端当前使用的是小区簇1，则用小区簇1的对应的系统更新消息所发送的时域和/或频域的资源位置去监听系统信息更新消息，如果接收成功，则用户终端认为是小区簇1的系统消息发生改变，便去读取和 更新当前正在使用的小区簇1的信息；如果不成功，则用户终端认为是小区簇1的系统消息没有发生改变，用户终端不触发更新过程。
以上，仅列举了一些指示信息的形式，本领域人员可以理解指示信息并不限于此，只要可以完成指示小区簇的系统消息发生改变，或者小区簇的系统消息是否发生改变的功能，或者完成指示小区簇中的小区的系统消息发生改变，或者小区簇中的小区的系统消息是否发生改变的功能，都可以实现本实施例的方案。

1601，网络设备，接收小区簇更新消息，所述小区簇更新消息，指示用户终端所使用的小区簇，所述小区簇包括至少一个小区的集合；
1602，网络设备，根据所述小区簇更新消息，确定寻呼范围，所述寻呼范围包括所述小区簇更新消息所指示的小区簇的小区的范围。
通过小区簇更新消息，网络设备可以知晓用户终端所使用的小区簇，从而可以知晓应该在什么样的范围发送该用户终端的寻呼消息。
可选的，所述网络设备，根据所述小区簇更新消息，确定寻呼范围，包括，所述网络设备根据所述小区簇更新消息，确定需要发送寻呼消息的小区 簇；所述网络设备确定需要发送寻呼消息的小区簇和TA信息，所述TA为所述网络设备的跟踪区(track area)；所述网络设备，确定寻呼的范围，所述寻呼的范围为所述TA和所述小区簇的交集范围。

可选的，还包括1603，网络设备使用所述寻呼范围发送寻呼消息。因为寻呼范围考虑到了用户终端的小区簇，所以在所述寻呼范围内与用户终端建立联系时，可以更有效或者更准确或者更快捷，从而节约资源。

可选的，所述网络设备包括，发送单元(未示出)，用于使用所述寻呼范围发送寻呼消息。因为寻呼范围考虑到了用户终端的小区簇，所以在只给所述寻呼范围内的基站设备发送该用户终端的寻呼消息时，可以更有效或者更准确或者更快捷，从而节约资源。
可选的，所述更新消息中携带该用户的小区簇信息，所述小区簇信息包括小区簇的标识或者索引；其中，所述小区簇的标识或者索引在该网络设备的管理区域的是统一分配的，或是在网络设备的管理区域内局部统一分配的，或是本地区域是统一分配的。在上述不同的管理区域内统一分配小区簇信息，可以灵活的在不同范围发起寻呼，从而更有效或者更准确或者更快捷，从而节约资源。
