Description

一种小区注册方法及装置 技术领域
本申请涉及电子技术领域，尤其涉及一种小区注册方法及装置。
背景技术
长期演进(Long Term Evolution，LTE)是由3GPP(The 3rd Generation Partnership Project，第三代合作伙伴计划)组织制定的UMTS(Universal Mobile Telecommunications System，通用移动通信***)技术标准的长期演进。LTE***网络架构更加扁平化简单化，减少了网络节点和***复杂度，从而减小了***时延，既可以提供高速移动中的通信需求，同时也降低了网络部署和维护成本。
但是，由于业务推广、投资成本等等各方面的原因，3G、LTE网络在相当长时期内只能先实现热点地区覆盖，不可能像全球移动通讯***(Global System for Mobile Communications，GSM)网络那样实现广覆盖。另一方面，GSM网络经过长时间的大规模商用建设，覆盖已经非常全面，网络质量也比较理想，是提供一般电路交换(Circuit Switched，CS)业务和分组交换(Packet Switched，PS)域业务的最佳手段。因此在一些场景中可能存在用户从LTE网络或3G网络覆盖范围移动到只有GSM网络覆盖范围的情况，在移动的过程中可能会导致用户无法进行正常通信的情况。
例如，当用户设备(User Equipment，UE)从LTE网络或者3G网络的覆盖范围移动到GSM网络覆盖范围后，UE需要重新注册GSM网络，但是，在一些网络信号较弱的GSM覆盖区域中，可能存在UE注册失败的问题，导致UE无法进行正常通信，用户体验较差。
发明内容

本申请实施例，通过在终端设备移动至GSM网络的覆盖范围且需要进行小区重选的情况下，读取第一小区的***消息SIB3，所述SIB3中包括所述终端设备驻留所述第一小区的第一信号强度阈值；若所述第一小区的当前信号强度小于所述第一信号强度阈值，且大于所述终端设备的预设小区驻留信号强度阈值，则注册所述第一小区。即本申请中通过在终端设备进入GSM网络覆盖范围且需要进行小区重选的情况下，首先判断需要注册的小区当前信号强度较弱，在未达到该小区的最小驻留信号强度条件下，进一步判断该小区的当前信号强度是否大于终端设备可以进行网络注册的预设小区驻留信号强度阈值，若大于，则可以在小区信号强度较弱但是终端设备却可以注册上小区的情况下，直接注册该小区，避免小区注册失败，解决终端设备在移动到GSM网络信号较弱的环境下可能发生的注册失败的问题，提升用户通信体验。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
以下分别进行详细说明。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端设备，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，如具有无线连接功能的手持式设备、车载设备等。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(Mobile Internet Device，MID)、可穿戴设备、智能手环、计步器、MP3播放器(Moving Picture Experts Group Audio Layer III，动态影像专家压缩标准音频层面3)、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面3)播放器、个人数字助理(Personal Digital Assistant，PDA)和膝上型便携计算机等。
2)、全球移动通信***Global System for Mobile Communication，GSM) 是当前应用最为广泛的移动电话标准。全球超过200个国家和地区超过10亿人正在使用GSM电话。GSM标准的无处不在使得在移动电话运营商之间签署"漫游协定"后用户的国际漫游变得很平常。GSM较之它以前的标准最大的不同是它的信令和语音信道都是数字式的，因此GSM被看作是第二代(2G)移动电话***。这说明数字通讯从很早就已经构建到***中。GSM是一个当前由3GPP开发的开放标准。
3)、GSM EDGE无线接入网络(GSM EDGE Radio Access Network，GERAN)。是GSM/EDGE的无线接入部分，它采用了增强型数据速率GSM演进技术(Enhanced Data Rate for GSM Evolution，EDGE)，网络组成与通用分组无线服务技术(General Packet Radio Service，GPRS)相同，包括机站(Base Stations，BS)和机站控制器(Base Station Controllers，BSC)以及它们的接口(Ater接口、Abis接口、A接口等)。
4)、“多个”是指两个或两个以上。“和/或”，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。字符“/”一般表示前后关联对象是一种“或”的关系。
图1是本申请实施例提供的一种小区注册方法的流程示意图，下面将结合附图1从终端设备侧对本申请实施例中的一种小区注册方法进行详细介绍，该方法包括以下步骤S101-步骤S103。
步骤S101：在终端设备移动至GSM网络的覆盖范围且需要进行小区重选的情况下，读取第一小区的***消息SIB3，所述SIB3中包括所述终端设备驻留所述第一小区的第一信号强度阈值。
具体地，终端设备可以是从LTE网络或3G网络覆盖范围移动至GSM网络覆盖范围，还可以是从较强信号强度的GSM网络覆盖范围移动至弱信号强度的GSM网络覆盖范围，即只要是最终移动至GSM网络覆盖范围，并且导致需要在GSM频点下重新选择小区进行注册的情况均属于本申请中的移动至GSM网络的覆盖范围的涵盖保护范围。
终端设备或者终端设备中的相关处理器或者相关处理模块(后续相同不再 赘述)在移动至GSM网络的覆盖范围后，在GERAN下即GSM的频点下发起功率扫描power scan，获取并读取当前需要接入的第一小区的***消息(System Information Block type3，SIB 3)，也可简称为SI3。该***消息SIB3中包含有终端设备需要驻留该第一小区所需要的最小接入信号强度值，即第一信号强度阈值。其中，SIB3的含义以及定义可以参见GSM协议的规定，具体可以参见3GPP TS44.018中的规定。可以理解的是，终端设备在发起power scan后，会扫描到多个小区的信息，即接收到多个小区的接收信号强度。可选地，第一小区可以是该多个小区中信号强度最强的小区，也可以是根据其它计算法则选择出需要驻留的小区，本申请对此不作具体限定。
步骤S102：若所述第一小区的当前信号强度小于所述第一信号强度阈值，且大于所述终端设备的预设小区驻留信号强度阈值，则注册所述第一小区。
具体地，由于在现有技术中，当判断出所述第一小区的当前信号强度小于第一信号强度阈值，即若判断出终端设备的接收到第一小区的信号强度(第一小区当前信号强度)小于***消息SIB3中携带的第一信号强度阈值时，则判定为该终端设备不满足最基本的小区驻留条件，即无法正常驻留该第一小区。但是，实质上每个终端设备其实都有不同的最低可接入并驻留小区的最低信号强度大小，即只要终端设备所接收到的小区信号强度大于该最低信号强度大小，则该终端设备是可以注册上该小区的，只是可能存在由于网络信号较弱导致通信状况不佳的问题，但是至少可以进行正常通信。例如，若小区当前的信号强度小于该小区的最小信号强度驻留条件，但是却满足终端设备自身的最低驻留条件，即此时，采用本申请实施例，可以忽略第一信号强度阈值，在进一步判断出信号强度大于终端设备的预设小区驻留信号强度阈值的情况下仍然继续注册该第一小区，进行通信。因此，只要在满足了本步骤中的条件时，则控制该终端设备继续进行第一小区的注册，以进行后续的通信流程。
在一种可能的实现方式中，终端设备的调制解调器Modem层预先存储终端设备的预设小区驻留信号强度阈值(例如-105dbm)，该阈值可以是在出厂前就由技术人员进行的出厂设置，也可以是终端设备在使用过程中，根据小区驻留的历史信息并结合相关算法计算得到的灵活变更的值，本发明对此不作具体 限定。
可以理解的是，若所述第一小区的当前信号强度大于所述第一信号强度阈值，则可以按照现有技术中的小区注册流程直接注册该第一小区。
本申请实施例，通过在终端设备移动至GSM网络的覆盖范围且需要进行小区重选的情况下，读取第一小区的***消息SIB3，所述SIB3中包括所述终端设备驻留所述第一小区的第一信号强度阈值；若所述第一小区的当前信号强度小于所述第一信号强度阈值，且大于所述终端设备的预设小区驻留信号强度阈值，则注册所述第一小区。即本申请中通过在终端设备进入GSM网络覆盖范围且需要进行小区重选的情况下，首先判断需要注册的小区当前信号强度较弱，在未达到该小区的最小驻留信号强度条件下，进一步判断该小区的当前信号强度是否大于终端设备可以进行网络注册的预设小区驻留信号强度阈值，若大于，则可以在小区信号强度较弱但是终端设备却可以注册上小区的情况下，直接注册该小区，避免小区注册失败，解决终端设备在移动到GSM网络信号较弱的环境下可能发生的注册失败的问题，提升用户通信体验。
图2是本申请实施例提供的另一种小区注册方法的流程示意图，下面将结合附图2从终端设备侧对本申请实施例中的另一种小区注册方法进行详细介绍，如图2所示，该方法可以包括以下步骤S201-步骤S207。
步骤S201：在终端设备移动至GSM网络的覆盖范围且需要进行小区重选的情况下，获取所述终端设备在所述GSM网络下小区信号强度测量信息。
具体地，在终端设备移动至GSM网络的覆盖范围且需要进行小区重选的情况下，终端设备通过power scan获取所述终端设备在所述GSM网络下小区信号强度测量信息，该小区信号强度测量信息中包括该终端设备所能检测并接收到信号的小区的测量信息。例如，小区信号强度测量信息可以为包含了终端设备所能检测接收到信号的小区信号强度列表。
步骤S202：根据所述小区信号强度测量信息确定当前信号强度最大的小区为第一小区。
具体地，根据步骤S201中的小区信号强度测量信息，确定终端设备当前 需要驻留的小区，假设按照驻留当前信号强度最大的小区的原则，确定当前信号强度最大的小区为第一小区。例如，终端设备可以从小区信号强度列表中择选出当前信号强度最强的第一小区，进行尝试注册，即首先需要获取该第一小区的***消息等。
步骤S203：读取第一小区的***消息SIB3，所述SIB3中包括所述终端设备驻留所述第一小区的第一信号强度阈值。
步骤S204：若所述第一小区的当前信号强度小于所述第一信号强度阈值，且大于所述终端设备的预设小区驻留信号强度阈值，则注册所述第一小区。
具体地，步骤S203至步骤S204可参考上述图1实施例中的步骤S101至步骤S102，这里不再赘述。
在一种可能的实现方式中，终端设备可以预先存储所述预设小区驻留信号强度阈值。进一步地，终端设备可以根据自身的小区注册历史记录更新所述预设小区驻留信号强度阈值。即该预设小区驻留信号强度阈值可以是灵活变动的，可以是根据终端设备的实际硬件、软件或参数设置的情况进行的个性化设定，本申请对此不作具体限定。
步骤S205：若所述第一小区的当前信号强度小于所述第一信号强度阈值，且小于所述终端设备的预设小区驻留信号强度阈值，则在预设时间段内禁止所述终端设备注册所述第一小区。
具体地，若终端设备判断出该第一小区的当前信号强度小于所述第一信号强度阈值，且小于所述终端设备的预设小区驻留信号强度阈值，即既不满足第一小区的驻留条件，也不满足该终端设备自身的最低信号强度注册条件，则在预设时间段内禁止所述终端设备注册所述第一小区。具体的实施方式可以是将该第一小区的小区标识加入到该终端设备的禁用注册小区列表中，即终端设备在后续又需要进行重新注册时，只要检测到小区的小区标识存储在该禁用注册小区列表则，在预设时间段内该终端设备不会再获取该小区的***消息也不会发起网络注册，以节省网络资源和不必要的网络开销。
可以理解的是，本申请对预设时间段不作具体限定，可以是较短的时间也可以是较长的时间，还可以是无限长时间。
步骤S206：若所述第一小区的当前信号强度小于所述第一信号强度阈值，且小于所述预设小区驻留信号强度阈值，则获取第二小区的***消息SIB3，其中，所述第二小区的***消息SIB3中包括所述终端设备驻留所述第二小区的第二信号强度阈值，所述第一小区的当前信号强度大于所述第二小区的当前信号强度；
具体地，当判断出该终端设备无法在第一小区上驻留时，则需要更换驻留目标，此时可以根据步骤S201中的终端设备的小区信号强度测量信息选择出信号强度次之的第二小区进行与第一小区同样的判断和操作，即获取第二小区的***消息SIB3，并在后续根据第二小区的第二信号强度阈值和该终端设备的预设小区驻留信号强度阈值判断是否可以驻留到该第二小区上，其中的判断原则与第一小区的判断原则类似，在此不再赘述。
步骤S207：若所述第二小区的当前信号强度小于所述第二信号强度阈值，且大于所述终端设备的预设小区驻留信号强度阈值，则注册所述第二小区。
具体地，若第二小区的信号强度小于所述第二信号强度阈值，且大于所述终端设备的预设小区驻留信号强度阈值，即表明虽然第二小区的驻留条件不满足，但是满足终端设备驻留小区的条件，因此向该第二小区发起注册流程。可以理解的是，若第二小区也无法驻留，则终端设备可以继续在信号强度列表查询其他可以驻留的小区，以此循环类推，直到可以成功注册到小区，进行正常通信为止。
在具体的应用场景中，如图3所示，图3是本发明实施例中小区注册的一个具体应用场景示意图，现有技术中当终端设备移动至GSM网络覆盖范围的情况下，可能会出现图3中左图所示的无法注册GSM网络的情况，但是应用了本申请实施例之后，就可以如图3中右图中所示正常注册上如联通的2G网络，更具体地，请参见上述方法实施例的说明。
本申请实施例，通过在终端设备移动至GSM网络的覆盖范围且需要进行小区重选的情况下，读取第一小区的***消息SIB3，所述SIB3中包括所述终端设备驻留所述第一小区的第一信号强度阈值；若所述第一小区的当前信号强度小于所述第一信号强度阈值，且大于所述终端设备的预设小区驻留信号强度 阈值，则注册所述第一小区。即本申请中通过在终端设备进入GSM网络覆盖范围且需要进行小区重选的情况下，首先判断需要注册的小区当前信号强度较弱，在未达到该小区的最小驻留信号强度条件下，进一步判断该小区的当前信号强度是否大于终端设备可以进行网络注册的预设小区驻留信号强度阈值，若大于，则可以在小区信号强度较弱但是终端设备却可以注册上小区的情况下，直接注册该小区，避免小区注册失败，解决终端设备在移动到GSM网络信号较弱的环境下可能发生的注册失败的问题，提升用户通信体验。
