将以所述第六子帧为起始子帧的连续m个子帧作为所述第三时域。
第二方面,本公开提供了一种网络搜索装置,包括:
信息获取模块,被设置为获取第一网络的配置信息,其中,所述配置信息被设置为指示时钟周期中的第一时域;
异频搜索模块,被设置为按照所述第一时域搜索第二网络的广播信号,其中,所述第二网络的频点与所述第一网络不同;在连续n个时钟周期的第一时域内未搜索到所述广播信号的情况下,按照所述时钟周期中的第二时域搜索所述第二网络的广播信号,其中,所述第二时域包括至少一个与所述第一时域内各时域不同的时域,n为预先配置的正整数;
网络切换模块,被设置为在时钟周期的第一时域内搜索到所述广播信号的情况下,将当前网络从所述第一网络切换为所述第二网络。
一种计算机设备,包括存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序,所述处理器执行所述计算机程序时实现以下步骤:
获取第一网络的配置信息,其中,所述配置信息被设置为指示时钟周期中的第一时域;
按照所述第一时域搜索第二网络的广播信号,其中,所述第二网络的频点与所述第一网络不同;
在时钟周期的第一时域内搜索到所述广播信号的情况下,将当前网络从所述第一网络切换为所述第二网络;
在连续n个时钟周期的第一时域内未搜索到所述广播信号的情况下,按照所述时钟周期中的第二时域搜索所述第二网络的广播信号, 其中,所述第二时域包括至少一个与所述第一时域内各时域不同的时域,n为预先配置的正整数。
一种计算机可读存储介质,其上存储有计算机程序,所述计算机程序被处理器执行时实现以下步骤:
获取第一网络的配置信息,其中,所述配置信息被设置为指示时钟周期中的第一时域;
按照所述第一时域搜索第二网络的广播信号,其中,所述第二网络的频点与所述第一网络不同;
在时钟周期的第一时域内搜索到所述广播信号的情况下,将当前网络从所述第一网络切换为所述第二网络;
在连续n个时钟周期的第一时域内未搜索到所述广播信号的情况下,按照所述时钟周期中的第二时域搜索所述第二网络的广播信号,其中,所述第二时域包括至少一个与所述第一时域内各时域不同的时域,n为预先配置的正整数。
基于上述网络搜索方法,终端先依照第一网络的配置信息搜索第二网络的广播信号,若依照配置信息中的第一时域搜索到第二网络的广播信号,则将终端的当前网络从第一网络切换为第二网络;若依照配置信息无法搜索到第二网络的广播信号,则采用第二时域搜索第二网络的广播信号。
按照配置信息无法搜索到第二网络的广播信号,通常情况下,表示广播信号不在配置信息中的第一时域内,这种情况可能是,由于第一时域与第二网络广播信号之间存在偏移,进而使得第二网络广播信号落在第一时域之外,因此此时仍然按照配置信息中的第一时域搜索,是无法搜索到第二网络广播信号的。
而本公开实施例中,在按照配置信息无法搜索到第二网络的广播信号时,采用第二时域搜索第二网络的广播信号,并且,所述第二时域包括至少一个与所述第一时域内各时域不同的时域,所以,第二时域的时域长度大于第一时域的时域长度。
使用时域长度大于第一时域的第二时域进行搜索,相当于扩大时域来搜索第二网络的广播信号,进而即使第二网络的广播信号与第一时域之间由于干扰而出现偏移,该方法仍然可以提高第二网络的广播信号的搜索成功率,进而使得终端能够不受干扰搜索到第二网络的广播信号,并将当前网络由第一网络切换为第二网络。

为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例中的附图,对本公开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公开的一部分实施例,而不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
图1为一个实施例中网络搜索方法的应用环境图。参照图1,该网络搜索方法应用于网络搜索系统。该网络搜索系统包括终端110、第一基站120和第二基站130。终端110与第一基站120之间通过网络连接。终端110具体可以是台式终端110或移动终端110,移动终端110具体可以为手机、平板电脑、笔记本电脑等中的至少一种。第一基站120对应的频段与第二基站130对应的频段不同,例如,第一基站120为4G基站,第二基站130为5G基站。终端110接入第二基站130需要通过第一基站120的辅助,第二基站130与第一基站120之间通过网络连接,第二基站130将其网络参数发送至第一基站120,第一基站120根据第二基站130的网络参数生成配置信息,第一基站120将配置信息通过网络发送至终端110,使终端110根据配置信息搜索第二基站130的广播信号,在终端110搜索到第二基站130的广播信号的情况下,与第二基站130进行同步连接。
在一个实施例中,图2为一个实施例中一种网络搜索方法的流程示意图,参照图2,提供了一种网络搜索方法。本实施例主要以该方法应用于上述图1中的终端110来举例说明,该网络搜索方法具体包括如下步骤:
步骤S210,获取第一网络的配置信息,其中,所述配置信息被设置为指示时钟周期中的第一时域。
在本实施例中,第一网络被设置为建立终端110与第一基站120 之间的第一频段的通信连接,第二网络被设置为建立终端与第二基站130之间的第二频段的通信连接,配置信息为第一基站120根据第二基站130的网络参数配置生成的信息,配置信息包括时钟周期、时钟周期内的第一时域和第二时域,第一时域为第一基站120根据第二基站130的网络参数计算得到的搜索时域,第二时域的时域长度长于第一时域。时钟周期被设置为表示两次进行异频搜索的时间间隔,即表示多久搜索一次第二网络的广播信号,第一时域和第二时域均被设置为表示每次搜索广播信号的持续时长。例如,时钟周期为80ms,第一时域为6ms,表示每隔80ms进行一次异频搜索,每次异频搜索持续6ms。
步骤S220,按照所述第一时域搜索第二网络的广播信号,其中,所述第二网络的频点与所述第一网络不同。
在本实施例中,第二网络被设置为建立第二基站130与终端110之间的通信连接,即第二网络的广播信号为第二基站130的广播信号,频点为固定频率的编号,不同的基站的发射频率和接收信号的频率各不相同,即第一基站120的频点与第二基站130的频点不同。在第一时域内搜索第二网络的广播信号,在此期间终端110暂停与第一基站120相关的通信业务。
通常各个基站小区之间不存在相互干扰,且第一基站120根据第二基站130的网络参数生成配置信息的过程准确无误的情况下,终端110可在第一时域内搜索到第二基站130的广播信号。
步骤S230,在时钟周期的第一时域内搜索到所述广播信号的情况下,将当前网络从所述第一网络切换为所述第二网络。
在本实施例中,在第一时域内搜索到广播信号,根据广播信号同步第二基站130的小区信息,加载第二基站130到当前通信连接中,将终端110的当前网络从与第一基站120通信的第一网络切换为与第二基站130通信的第二网络,继而开始与第二基站130相关的通信业 务。
步骤S240,在连续n个时钟周期的第一时域内未搜索到所述广播信号的情况下,按照所述时钟周期中的第二时域搜索所述第二网络的广播信号,其中,所述第二时域包括至少一个与所述第一时域内各时域不同的时域,n为预先配置的正整数。
在本实施例中,由于异频搜索期间终端110无法执行业务处理,所以异频搜索时长越短越好,第二时域的时长大于第一时域,因此,先依照时长较短的第一时域搜索第二基站130的广播信号,在第一时域内无法搜索到广播信号的情况下,再采用时长较长的第二时域进行异频搜索,避免在第一时域内能够搜索到广播信号的情况下,仍占据较长的时间进行异频搜索,影响终端110进行正常的数据业务处理。
在连续n个时钟周期的第一时域内未搜索到所述广播信号,即连续n次在第一时域内搜索广播信号失败,表示第一基站120与第二基站130之间存在信号干扰,或第一基站120存在错配现象,依照第一时域无法搜索到第二基站130的广播信号,则需要根据时域时长更长的第二时域搜索第二基站130的广播信号,从而提高搜索广播信号的成功率。
n为预先配置的正整数,但该数值不宜过大,通常n设定为2或3,n越大,越晚根据第二时域搜索广播信号,以此减慢了网络切换速率;n越小,越早根据第二时域搜索广播信号,可尽快搜索到广播信号,尽早接入5G网络。
在第二时域内搜索到第二基站130的广播信号,则与步骤S230同理,根据广播信号同步第二基站130的小区信息,加载第二基站130到当前通信连接中,将终端110的当前网络从与第一基站120通信的第一网络切换为与第二基站130通信的第二网络,继而开始与第二基站130相关的通信业务。
在第二时域内未搜索到第二基站130的广播信号,表示终端110附近没有第二基站130服务小区,或距离第二基站130较远,则执行获取第一网络的配置信息的步骤。
在第二时域内进行异频搜索,影响终端110进行数据业务处理,所以,需要降低依照第二时域进行异频搜索的使用频次,通常在连续n个时钟周期的第一时域内未搜索到所述广播信号,即连续n次在第一时域内搜索广播信号失败。
在一个实施例中,每个所述时钟周期包括多个无线帧,每个无线帧包括连续的多个子帧,其中,按照时钟周期中的第二时域搜索所述第二网络的广播信号包括:确定所述时钟周期内的目标无线帧,其中,所述目标无线帧包括所述第一时域中各子帧所在的帧;将所述目标无线帧中的所有子帧作为所述第二时域;在所述第二时域的各个子帧内搜索所述第二网络的广播信号。
在本实施例中,一个无线帧包括10ms,1ms对应一个子帧,时钟周期包括多个无线帧,时钟周期内的目标无线帧包括至少一个无线帧,目标无线帧的时长与配置信息中的异频广播周期相等,异频广播周期被设置为表示第二基站130发送广播信号的频率。将所述目标无线帧中的所有子帧作为所述第二时域,即目标无线帧相当于第二时域,目标无线帧的时长与第二时域的时长相等,第二时域中子帧的数量大于第一时域中子帧的数量。
例如,异频广播周期为20ms,目标无线帧=第二时域=20ms,第二时域内包括20个子帧,20个子帧中包括第一时域内所有子帧。按照第二时域搜索5G广播信号,可以覆盖实际第二基站130的频点位置,确保终端110附近存在第二基站130的情况下,能够使终端110搜索到第二基站130的广播信号。
参照图3,第一时域包含子帧3至子帧8的6个子帧,时钟周期为 80ms,即第6帧内的第一时域与第14帧内的第一时域间隔80ms,n为3,即按照时间先后顺序依次在第6帧、第14帧和第22帧均未搜索到第二基站130的广播信号,第二时域包含20个子帧,即第二时域包含两帧,根据第二时域搜索广播信号,即在第6帧和第7帧内进行异频搜索,搜索到广播信号位于第6帧内的子帧1处。
在一个实施例中,按照时钟周期中的第二时域搜索所述第二网络的广播信号之后,所述方法还包括:在按照时钟周期中的第二时域搜索到所述广播信号的情况下,根据所述第二时域对所述第一时域的起始子帧进行调整,得到第三时域,其中,所述第一时域中包括连续的多个子帧,所述第三时域包括所述第二时域中搜索到所述广播信号时所在的子帧,所述第三时域包括的子帧数与所述第一时域包括的子帧数均为m,m为正整数。
在本实施例中,参照图4,根据所述第二时域对所述第一时域的起始子帧进行调整,表示根据在第二时域内的搜索广播信号的搜索结果对配置信息中的第一时域进行矫正,得到矫正后的第一时域,即第三时域,所以第一时域与第三时域内的子帧数均为m,子帧数m为第一基站120的配置结果,通常m=6,即第一时域=第三时域=6ms,将包含有第三时域的配置信息保存在终端110内,在后续需要接入5G网络时,无需重新根据第一基站120配置的配置信息搜索第二基站130的广播信号,直接根据终端110内存储的配置信息中的第三时域搜索第二基站130的广播信号,加快了终端110从4G网络切换为5G网络的网络切换速率,若后续根据第三时域无法搜索到第二基站130的广播信号,则执行步骤S240,通过第二时域重新确定第二基站130的频点位置,继而调整终端110内配置信息。
第一时域的起始子帧由配置信息中的配置时域决定,第一时域的起始子帧为所述配置时域除以10之后得到的余数,第一时域的起始搜 索帧为配置时域除以10之后得到的商。例如,配置时域为63,时钟周期为80ms,第一时域的起始子帧为63mod10=3,第一时域的起始搜索帧为63/10=6,即终端110从第6帧中的第3子帧开始进行异频搜索,第一时域的异频搜索帧为(a*8+6),其中,a被设置为指示累计异频搜索次数,a=0时,确定起始搜索帧为第6帧,a=1时,确定异频搜索帧为第14帧,以此确定每一个需要进行异频搜索的帧。
在一个实施例中,根据所述第二时域对所述第一时域的起始子帧进行调整,得到第三时域,包括:确定所述第一时域中位于起始位置的第一子帧与第二子帧之间的第一间隔子帧数,其中,所述第二子帧为所述第二时域中搜索到所述广播信号时所在的子帧;确定所述第一时域中位于终止位置的第三子帧与所述第二子帧之间的第二间隔子帧数;在所述第一间隔子帧数小于所述第二间隔子帧数的情况下,将以所述第二子帧为起始子帧的连续m个子帧作为所述第三时域。
在本实施例中,参照图4,第一时域中位于起始位置的第一子帧为子帧3,第二子帧为子帧1,表示在子帧1处搜索到第二基站130的广播信号,第一子帧与第二子帧之间的第一间隔子帧数为X1=3-1=2,第三子帧为子帧8,第三子帧与第二子帧之间的第二间隔子帧数为X2=8-1=7,此时X2>X1,即确定第二基站130的频点位置位于第一时域之前,则需要将第一时域前移才可使第一时域覆盖到广播信号的频点位置,以子帧1为起始子帧的连续6个子帧作为第三时域,即将第一时域的起始子帧从子帧3迁移至子帧1,将第一时域的结束子帧从子帧8迁移至子帧6,迁移后的时域为第三时域,图4中第6帧中6个连续子帧对应的时域为第三时域,第14帧和第22帧参照第6帧的迁移方式迁移第一时域。
在一个实施例中,根据所述第二时域对所述第一时域的起始子帧进行调整,得到第三时域,包括:在所述第一间隔子帧数大于所述第 二间隔子帧数的情况下,确定位于所述第一子帧之后,且与所述第一子帧之间相距所述第二间隔子帧数的第四子帧;将以所述第四子帧为起始子帧的连续m个子帧作为所述第三时域。
在本实施例中,第一间隔子帧数大于第二间隔子帧数,表示第二基站130的频点位置位于第一时域之后,需要将第一时域后移才可覆盖到第二基站130的频点位置,根据第二间隔子帧数将第一时域向后迁移,即将第一时域的起始子帧从第一子帧迁移至第四子帧,迁移后的子帧个数不变,第三时域为迁移后的第一时域。
参照图5,第二子帧为子帧9,第一间隔子帧数为X1=9-3=6,第二间隔子帧数为X2=9-8=1,此时X1>X2,在第一子帧之后,且与第一子帧相距第二间隔子帧数的第四子帧为子帧4,即将第一时域的起始子帧从子帧3迁移至子帧4,将第一时域的结束子帧从子帧8迁移至子帧9,迁移后的时域为第三时域,图5中第6帧中6个连续子帧对应的时域为第三时域,第14帧和第22帧参照第6帧的迁移方式迁移第一时域。
在一个实施例中,根据所述第二时域对所述第一时域的起始子帧进行调整,得到第三时域,包括:获取冗余子帧数;在所述第一间隔子帧数小于所述第二间隔子帧数的情况下,将所述冗余子帧数与所述第一间隔子帧数相加,得到第一偏移子帧数,其中,所述第一间隔子帧数为所述第一时域中位于起始位置的第一子帧与第二子帧之间间隔的子帧数,所述第二子帧为所述第二时域中搜索到所述第二网络的广播信号时所在的子帧,所述第二间隔子帧数为所述第一时域中位于终止位置的第三子帧与所述第二子帧之间间隔的子帧数;确定位于所述第一子帧之前,且与所述第一子帧之间相距所述第一偏移子帧数的第五子帧;将以所述第五子帧为起始子帧的连续m个子帧作为所述第三时域。
在本实施例中,从配置信息中获取冗余子帧数,冗余子帧数被设置为增加第一时域的迁移量,确保广播信号的频点位置位于迁移后的第三时域内,冗余子帧数记为S,在所述第一间隔子帧数小于所述第二间隔子帧数的情况下,第一偏移子帧数为Y1=X1+S,参照图6,例如,S=1,X1=3-1=2,则Y1=2+1=3,将第一时域向前迁移3个子帧位置,其中,第二基站130的频点位置位于子帧1,第一时域的起始子帧由子帧3迁移至子帧0,确保能够完全覆盖第二基站130的频点位置,提高后续搜索异频信号的搜索成功率。图6中第6帧中6个连续子帧对应的时域为第三时域,第14帧和第22帧参照第6帧的迁移方式迁移第一时域。
在一个实施例中,最好令冗余子帧数的取值能够使第二基站130的频点位置位于第三时域内中间的子帧位置,避免基站之间不同程度的干扰,导致频点位置偏移出第三时域。
在一个实施例中,根据所述第二时域对所述第一时域的起始子帧进行调整,得到第三时域,包括:在所述第一间隔子帧数大于所述第二间隔子帧数的情况下,将所述冗余子帧数与所述第二间隔子帧数相加,得到第二偏移子帧数;确定位于所述第一子帧之后,且与所述第一子帧之间相距所述第二偏移子帧数的第六子帧;将以所述第六子帧为起始子帧的连续m个子帧作为所述第三时域。
在本实施例中,通过冗余子帧数增加第一时域的迁移量,确保广播信号的频点位置位于第三时域内,参照图7,在所述第一间隔子帧数大于所述第二间隔子帧数的情况下,例如,S=1,X2=9-8=1,则Y2=X2+S=1+1=2,将第一时域向后迁移2个子帧位置,其中,第二基站130的频点位置位于子帧9,第一时域的起始子帧由子帧3迁移至子帧5,第一时域的结束子帧由第6帧中的子帧8迁移至第7帧中的子帧0,确保能够完全覆盖第二基站130的频点位置,提高后续搜索异频信 号的搜索成功率。图7中第6帧中6个连续子帧对应的时域为第三时域,第14帧和第22帧参照第6帧的迁移方式迁移第一时域。
