Description

一种终端驻留小区的方法、 装置及移动终端 技术领域
本发明涉及通信领域， 尤其涉及一种终端驻留小区的方法、 装置及移动 终端。
背景技术
目前移动终端通过对小区网络进行搜索、 找到可驻留的小区， 通过驻留 获取网络服务。
当移动终端从网络盲区进入网络覆盖区时， 移动终端将遍历 PLMN ( Public Land Mobile Network, 公共陆地移动网络 )允许的所有频点， 并选择 合适的小区驻留， 这个过程被称为小区选择。
移动终端驻留的小区称为服务小区。 在现有技术中， 移动终端周期性的 进行重选检测， 具体的， 移动终端根据该服务小区的 BCCH(Broadcast Control Channel, 广播控制信道)系统消息所指示的小区重选邻区频点配置表， 对该表 中 BCCH载波接收的所有邻区电平和邻区同步消息进行监测， 将接收到的邻 区电平按由高至低排列， 并提取每个邻区的各类系统消息和控制消息， 当表 中某个邻区的综合条件优于当前的服务小区时， 移动终端将重新选择这个邻 区作为新的服务小区， 这个过程被称为小区重选； 当任何一个邻区的综合条 件都低于当前的服务小区时， 移动终端选择仍然在该服务小区驻留， 不会重 选到邻区。
在移动终端实际进行小区选择和小区重选的过程中， 出现了如下问题： 移动终端在进行初次小区选择时， 若 PLMN允许的所有频点中没有合适 的小区进行驻留， 移动终端会直接进入无服务状态。 另外， 移动终端周期性 在进行小区重选检测时， 若没有合适的邻区可供移动终端驻留， 并且当前服 务小区因网络覆盖变差而不满足接入要求， 移动终端会掉网。 发明内容

尤其是在话务量较高的地区， 这些地区即使信号覆盖良好也可能存在通 话质量不佳的情况， 此情况下本发明实施例结合信号强度和历史驻留成功率 两个因素来选取有效小区， 提高移动终端的小区接入成功率， 提升通话质量。
进一步的， 若可选小区的小区信号值不能满足标准小区接入准则， 本发 明实施例还提供了一种终端驻留小区的方法， 如图 4所示， 包括：
401、 若所述可选小区的小区信号值不满足标准小区接入准则， 将不满足 所述标准小区接入准则的可选小区进行标识。
移动终端可以检测到多个可选小区信号， 而小区接入有艮多匹配条件， 信号强度符合标准小区接入准则是其中一种匹配条件， 此外还有其他的匹配 条件。 举例来说， 一种匹配条件是网络的 PLMN, 如移动终端使用中国移动 SIM卡， 则在接收的多个小区信号中， 将中国移动 GSM网络（其 PLMN值 为 460-0 ) 的小区作为符合匹配条件的小区， 其他网络的小区信号不予考虑。
该步骤 401 之前， 移动终端已经对可选小区信号进行其他匹配条件的检 测， 确定小区信号符合其他匹配条件。
402、 若遍历所有小区后未找到小区信号值满足所述标准小区接入准则的 小区， 将所述标识的小区作为有效小区。
根据 401的描述， 移动终端对小区进行了标识。 根据 402的描述， 如果 移动终端遍历小区后没有找到满足标准小区接入准则的小区， 此时为避免移 动终端进入无服务状态， 移动终端将 401 中标识的小区作为服务小区。 如果 不存在标识的小区， 则移动终端进入无服务状态。
403、 所述移动终端对所述有效小区的信号值复合补偿值， 并在所述有效 小区驻留。
为保证信号强度， 将有效小区的小区信号值复合对应的补偿值， 以便有 效小区为移动终端提供可靠的网络服务， 所述补偿值预设置在所述移动终端。
如果有效小区有多个， 则可以选择首先找到的进行驻留。
关于复合的描述， 可以参考步骤 304。
本发明实施例提供的终端驻留小区的方法， 移动终端将不满足标准小区 接入准则的可选小区进行标识， 并通过使用补偿值对标识小区信号进行补偿 得到有效信号， 从而向有效信号的小区驻留， 由此可以使移动终端在重选小 区或小区切换时， 尽可能的找到小区进行驻留， 避免进入无服务状态。
现有技术中如果存在其他方面符合接入的匹配条件、 但是信号强度略弱 (不满足标准小区接入准则） 的小区， 移动终端并不能驻留该小区； 而本发 明实施例的方案可以从各小区中选取一个其他方面符合接入的匹配条件、 但 是信号强度略弱的小区， 对该小区信号进行信号补偿， 使该小区能够为用户 提供网络服务。
另一方面，如图 lb所示，本发明实施例还提供一种终端驻留小区的方法， 包括：
101b, 移动终端获取 Λ良务小区信号和相邻小区信号。
102b, 若存在满足标准小区接入准则的服务小区信号值或相邻小区信号 值， 所述移动终端选择信号最优的服务小区或相邻小区作为有效小区。
具体的， 在满足标准小区接入准则的服务小区信号值和相邻小区信号值 中选择最优信号值对应的服务小区或相邻小区作为有效小区。
103b, 若不存在满足标准小区接入准则的服务小区信号值或相邻小区信 号值， 在所述服务小区信号值和所述相邻小区信号值中选取小区信号值进行 补偿值复合预估， 得到有效小区。
当不存在满足标准小区接入准则的小区信号值时， 移动终端在服务小区 信号值和相邻小区信号值中选取小区信号值， 进行补偿值复合预估的操作。 该预估操作通过将小区信号值与补偿值做复合计算， 并比较各个计算结果， 将计算结果最大的小区信号值所在的小区选为有效小区。
104b, 所述移动终端对所述有效小区的信号值复合对应的所述补偿值， 并在所述有效小区驻留。
步骤 103b通过补偿值复合预估得到有效小区后， 移动终端在步骤 104b 中对接收到的有效小区的信号值进行补偿值复合操作， 从而得到了增强的有 效小区信号， 并在该有效小区驻留。
其中， 所述有效小区的小区信号复合对应的所述补偿值用于供所述移动 终端驻留。
本发明实施例提供的一种终端驻留小区的方法， 由移动终端获取服务小 区信号和相邻小区信号， 在满足标准小区接入准则的服务小区或相邻小区中 选择信号最优的服务小区或相邻小区， 作为有效小区供移动终端驻留； 当服 务小区的小区信号值不符合标准小区信号的标准小区接入准则时， 在服务小 区和相邻小区中选取小区进行补偿值复合， 得到有效小区进行驻留， 从而使 移动终端在重选小区或小区切换时， 提升了找到可驻留的小区的成功率， 降 低了使移动终端进入无服务状态的可能， 便于为用户提供网络服务。
上述图 la和图 lb分别描述了一种终端驻留小区的方案， 下面分别对这 两种方案进行展开说明。
如图 2所示， 本发明实施例提供了一种终端驻留小区的方法， 包括：
201、 移动终端获取 Λ良务小区信号和相邻小区信号。
202、 当服务小区的小区信号值或相邻小区信号值满足标准小区接入准则 时， 移动终端获取记录在本地的历史驻留小区。
当服务小区的小区信号值和相邻小区信号值都不能满足标准小区接入准 则时， 移动终端进入无服务状态。 203、 对所述历史驻留小区与相邻小区和服务小区取交集， 得到待选小区 集合。
204、 根据所述待选小区集合中的每个小区的信号值， 历史驻留成功率， 获得待选小区集合中的每个小区的接入可行系数。
可选的， 接入可行系数根据每个小区的信号值强度和历史驻留成功率得 到，其中所述历史驻留成功率 =驻留成功次数 /(驻留失败次数 +驻留成功次数）。
举例来说， 设小区 n的信号值为 Ρη , 历史驻留成功率为 Sn, 为信号强度 值分配权重系数 kl ,为历史驻留成功率分配权重系数 k2。 则通过公式
kl*Pn+k2*Sn
可以得到小区 n的加权和， 即接入可行系数。 在待选小区集合中的 N个 小区中选出加权和最大的小区作为有效小区进行驻留。 实际应用中， 根据通 便平衡信号值强度和历史驻留成功率之间的比重关系。
205、 选取所述接入可行系数最高的小区作为所述有效小区。
206、 所述移动终端在有效小区驻留。
在移动终端中， 可以建立一张数据表， 如表 1所示。
Figure imgf000015_0001
表 1
初次驻留某小区时， 会将该驻留的小区记录在移动终端中。 比如移动终 端驻留全球小区标识为 ID1的小区时，检测在数据表中是否已经存在 ID1 ,如 果不存在， 则 在表 1中添加一条项目， 记录全球小区标识 ID1 , 并将驻留成 功次数 Successl设置为 1。 之后， 如果移动终端因接入失败或切换小区， 从 ID1小区转移至至其他小区进行驻留， 则 Faill加 1 , 如果移动终端再次驻留 ID1小区， 则将驻留成功次数 Successl加 1 , 由此可获得驻留成功次数和驻留 失败次数的累加值。 这样在执行上述 204时， 获取了每个记录在表 1 中的小 区的驻留成功次数和驻留失败次数， 并算得驻留成功率。
实际应用中， 如果用户对移动终端进行恢复出厂设置操作， 则在恢复出 厂设置的过程中， 移动终端将清除该数据表。 在移动终端处于关机或飞行模 式时， 数据表内容可写入非易失性随机访问存储器中， 以保存该数据表内容， 在移动终端开机或取消飞行模式后， 从非易失性随机访问存储器中读出该数 据表。
本发明实施例提供的技术方案中， 通过在移动终端中记录历史驻留小区 以及驻留成功次数和驻留失败次数， 在待选小区集合中驻留成功率较高的小 区并结合小区的信号值强度选出有效小区进行驻留， 实现移动终端的接入， 尤其在小区负荷较大的繁华区域和高话务量区域， 除了考虑小区信号值强度， 还引入历史驻留成功率来选择小区， 结合小区的信号值强度和历史驻留成功 率来选择小区， 能够减少随机进行小区接入时可能造成的接入失败次数， 不 但提高了服务质量， 而且可以节省资源。
另一方面， 本发明实施例还提供了一种终端驻留小区的方法， 如图 3 所 示， 包括：
301、 移动终端获取 Λ良务小区信号和相邻小区信号。
302、 判断服务小区信号值或相邻小区信号值是否满足标准小区接入准 则。
根据现有技术的标准， 移动终端会周期性的触发重选检测， 判断小区信 号值是否满足标准小区接入准则， 目的在于找到信号最优的小区， 如果信号 最优的小区为相邻小区， 则移动终端将执行重选动作， 驻留到相邻小区中， 如果信号最优的小区仍然为当前的服务小区， 则移动终端继续在当前的服务 小区驻留。 移动终端在服务小区和邻区中选信号最优的小区进行驻留， 具体 实现过程为现有技术内容， 此处不再说明。
若服务小区信号值和相邻小区信号值都不符合标准小区信号的标准小区 接入准则， 执行 304, 否则执行 303。 303后执行 309。
303、 所述移动终端将所述服务小区或相邻小区作为有效小区。
当有两个以上小区的信号值符合标准小区接入准则时， 可选择信号最优 的小区作为有效小区。
如 303 所述， 服务小区或相邻小区中的信号值如果满足标准小区接入准 则， 则无需执行后续步骤 304至 308, 以及步骤 310。
当服务小区或相邻小区中至少一个小区的信号值满足标准小区接入准 则， 执行 303。 选取一个信号值满足标准小区接入准则的小区作为有效小区。
304、 将所述相邻小区信号值分别与对应的补偿值复合， 得到复合相邻小 区信号值集合。
举例来说，相邻小区信号值为 S1,补偿值为 C,则复合后的相邻小区信号值 为 Sl+C。
其中， 所述补偿值预设置在所述移动终端中。
具体的， 补偿值根据网络下发的网络接入门限进行调整， 比如补偿值可 以设定为网络接入门限值或大于网络接入门限值， 在 WCDMA系统中， 该网 络接入门限值为被设定为 Qqualmin, 在 GSM 系统中， 该网络接入门限值设 定为 rxlev— access— min。
305、 从所述复合相邻小区信号值集合中选出信号值最大的最大复合相邻 小区信号值。
306、 将所述服务小区的服务小区信号值与对应的补偿值复合， 得到复合 服务小区信号值。
其中上述步骤 306可在步骤 304之前执行， 也可在步骤 304之后执行。
307、 若所述复合服务小区信号值大于所述最大复合相邻小区信号值且满 足标准小区接入准则， 则所述移动终端将所述复合服务小区信号值对应的服 务小区选取为有效小区。 举例来说， 在 WCDMA系统中， 最大复合相邻小区信号为 Rank— n, 复合 服务小区信号为 Rank— s。 当 Rank— n<Rank— s, JL Squal>0, 此时移动终端将复 合服务小区信号对应的服务小区作为有效小区。
本发明实施例的前文中提及了 Squal准则， 该准则具体应用在 WCDMA 系统时， 可以理解为一个 Squal值， 具体描述可参考 3gpp协议 TS 25.304 第 5.2.3.1.2小节。
在 GSM中， 最大复合相邻小区信号为 NC2, 复合服务小区信号为 SC2。 当 NC2<SC2,且 C1>0,此时移动终端将复合服务小区信号对应的服务小区作 为有效小区。
本发明实施例的前文中提及了 C1准则，该准则具体应用在 GSM系统时， 可以理解为一个 C1值， 具体描述可参考 3gpp协议 TS05.08 第 6.4小节。
步骤 307后， 执行 309。
308、 若所述最大复合相邻小区信号值大于所述复合服务小区信号值且满 足标准小区接入准则， 则所述移动终端将所述最大复合相邻小区信号值对应 的相邻小区作为有效小区。
举例来说， 在 WCDMA中， 最大复合相邻小区信号为 Rank— n, 复合服务 小区信号为 Rank— s。 当 Rank— n>Rank— s, JL Squal>0, 此时移动终端将最大复 合相邻小区信号对应的相邻小区作为有效小区。
在 GSM中， 最大复合相邻小区信号为 NC2, 复合服务小区信号为 SC2。 当 NC2>SC2,且 C1>0,此时移动终端将最大复合相邻小区信号对应的相邻小 区作为有效小区。
步骤 308后， 执行 309。
步骤 304至 306中， 描述了将相邻小区信号值、 服务小区接入值分别与 补偿值进行复合， 得到最大复合相邻小区信号、 复合服务小区信号的过程。 之后在步骤 307 中， 复合服务小区信号满足标准小区接入准则， 且复合服务 小区信号大于最大复合相邻小区信号， 表明复合服务小区信号能够提供接入 信号， 因此移动终端将复合服务小区信号对应的服务小区作为有效小区， 准 备进行驻留。 步骤 308 中， 最大复合相邻小区信号满足标准小区接入准则， 且最大复合相邻小区信号大于复合服务小区信号， 表明最大复合相邻小区信 号能够提供接入信号， 因此移动终端将最大复合相邻小区信号对应的相邻小 区作为有效小区， 准备进行驻留。
上述步骤 304至 308是对前文图 lb中的补偿值复合预估的具体展开说明。
309、 移动终端在所述有效小区驻留。
其中， 移动终端在该有效小区驻留时， 移动终端需要复合该有效小区对 应的补偿值， 以弥补小区原始信号值小于标准小区接入准则的问题。 关于复 合的具体描述， 可参考本发明实施例前文步骤 304的说明。
除了上述 307和 308的两种情况， 还可能出现一种情况：
310、 最大复合相邻小区信号和复合服务小区信号都不满足标准小区接入 准则， 移动终端进入无服务状态。 该情况下不论是服务小区还是相邻小区， 都不适宜移动终端进行驻留。 此时移动终端进入无服务状态， 再等待一段时 间后重新发起图 3 所述的流程。 具体的可在移动终端中设置一个定时器， 当 定时器计满预定时长时， 重新发起图 3所述流程。
需要说明的是， 当移动终端处于某个服务小区时， 其周围有多个相邻小 区。 移动终端对每个相邻小区进行遍历， 确定是否存在可以进行驻留的有效 小区。
由于补偿值的复合可能导致信号的失真， 因此当原始信号值不小于标准 小区接入准则时可以停止提供补偿值。 具体的， 终端可以设置一个定时器 T— Optm, 在步骤 305、 306或 307之后， 启动该定时器 T— Optm进行计时。 假 设计时的时长为 30秒， 当计满 30秒时， 终端重新检测服务小区的小区信号。 如果此时的服务小区信号经 Squal/Cl准则的运算后的结果大于网络接入门限 值（如前文所述的 Qqualmin和 rxlev— access— min ) , 则终端可以停止提供补偿 值， 并按照现有技术的默认方式接入服务小区。 为保证结果的进一步准确性， 服务小区信号经 Squal/Cl准则的运算后的结果不但大于网络接入门限， 而且 要大于网络接入门限和调整值之和， 则此时终端可以停止提供补偿值并按照 现有技术的默认方式接入服务小区， 该调整值可设置为 5dbm。
本发明实施例提供的终端驻留小区的方法， 通过使用补偿值对相邻小区 信号值和服务小区接入值分别做复合预估得到最大复合相邻小区信号值和复 合服务小区信号值， 通过比较最大复合相邻小区信号值、 复合服务小区信号 值以及标准小区接入准则之间的关系， 选出有效小区进行驻留， 从而使移动 终端在重选小区或小区切换时， 提升了向小区驻留的可能性， 减少了使移动 终端进入无服务状态的可能， 便于为用户提供网络服务。
