如图1所示,该***架构包括基站110、基站120、基站130和终端设备100。以终端设备100支持SIM卡1和SIM卡2为例,SIM卡1和SIM卡2所属的运营商网络可以相同,也可以不相同。其中,每个SIM卡可以附着在其所属的运营商网络的基站下的小区。
例如,SIM卡1和SIM卡2都属于***SIM卡,基站110、基站120和基站130均支持***运营商网络,那么终端100包括的SIM卡1和SIM卡2可以附着在基站110、基站120或基站130下的任一个小区。例如,SIM卡1和SIM卡2可以分别附着到基站110下的小区和基站130下的小区;又如,SIM卡1和SIM卡2可以同时附着到基站130下的小区。
又如,SIM卡1和SIM卡2都属于***SIM卡,基站110支持***运营商网络,基站120和基站130均支持中国电信运营商网络,那么SIM卡1和SIM卡2可以都附着到基站110下的小区,但不能附着在基站120和基站130下的小区。
又如,SIM卡1属于中国电信SIM卡,SIM卡2属于***SIM卡,基站110和基站120支持中国电信运营商网络,基站130支持***运营商网络,那么SIM卡1可以附着在基站110或基站120下的小区,SIM卡2可以附着在基站130下的小区。

以终端设备支持两个实体SIM卡(如SIM卡1和SIM卡2)为例,如图3所示,双卡终端设备的射频模块可以包括天线和与天线连接的射频电路。在具体实现时,射频电路基于基带射频接口协议进行信号处理。其中,基带射频接口协议标准包括但不限于2G标准、3G标准、4G标准、5G标准或者以后的下一代标准等,使得卡1和卡2可以支持多种网络制式。例如,2G标准包括GSM标准和CDMA标准。3G标准包括WCDMA标准、CDMA2000标准和时分同步码分多址(Time division synchronous code division multiple access,TD-SCDMA)标准。4G标准包括时分双工LTE(time division duplex LTE,TDD-LTE)标准和频分双工(frequency division duplex LTE,
FD-LTE)标准。5G标准包括NR标准。通常,SIM卡模块(包括第一SIM卡和第二SIM卡)通过解调(Modem)模块与终端设备的其他模块(如射频电路)连接,如图3所示。通常,Modem模块用于完成无线信号的接收、解调、译码、以及信号的编码、调制和发送,以进行数据通信。
为方便理解,以下对本申请实施例可能出现的术语进行解释。
(1)、帧结构:以TDD-LTE***帧结构为例,根据第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)的定义,TDD-LTE***帧结构可以参考图4。
例如,一个10ms帧被分为两个5ms半帧,如图4所示,每个5ms半帧由4个1ms数据子帧(如图4所示子帧#0、子帧#2、子帧#3和子帧#4)和1个1ms特殊子帧(如图4所示特殊子帧#1)构成。每个1ms数据子帧可以分为两个0.5ms时隙,每个0.5ms时隙又可分为7个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号(symbol)。特殊子帧则由三个特殊时隙组成:下行导频时隙DwPTS,保护间隔GP和上行导频时隙UpPTS。三个特殊时隙的长度支持9种配置选项。通常,UpPTS的长度为1~2个OFDM符号;DwPTS的长度为3~12个OFDM符号;GP的长度为1~10个OFDM符号。
(2)、同步信号:以TDD-LTE***为例,TDD-LTE***中的同步信号包括主同步信号(primary synchronization signal,PSS)和辅同步信号(secondary synchronization signal,SSS)。
(3)、PSS:PSS主要用于完成小区搜索的过程中快速地确定符号/帧的起始位置, 即符号定时同步。以TDD-LTE***为例,如图1所示,PSS通常位于子帧#1和子帧#6的第3个OFDM符号。其中,子帧#6是10ms帧的第二个5ms半帧的第二个1ms子帧。
通常,基站将组内标识N
ID
(2)值(取值范围是0-2)与一个根序列索引u相关联,然后编码生成1个长度为62的ZC序列du
(n),并映射到PSS对应的RE(resource element)中,终端设备通过盲检测序列便可以获取当前小区的N
ID
(2)。
(4)、SSS:SSS主要用于与PSS共同确定物理小区ID。以TDD-LTE***为例,SSS通常位于子帧#0和子帧#5的最后一个OFDM符号中。即,SSS比PSS提前3个OFDM符号。其中,子帧#5是10ms帧的第二个5ms半帧的第一个1ms子帧。
通常,基站通过组标识N
ID
(1)值(取值范围是0-167)生成两个索引值m0和m1,然后引入组内标识N
ID
(2)的值编码生成2个长度均为31的序列d
(2n)和d
(2n+1),并映射到SSS的RE中,终端设备通过盲检测序列就可以知道当前基站下发的是哪种序列,从而获取当前小区的N
ID
(1)。
需要说明的是,图4仅以TDD-LTE***帧结构作为示例,对于不同的网络制式,帧结构可能不同。或者,对于不同的网络制式,帧结构可能相同,但是PSS和/或SSS在帧结构中的位置可能不同。例如,在FDD-LTE***中,PSS通常在子帧#0的第一个时隙的最后一个OFDM符号中发送,SSS通常在子帧#0的第二个时隙的倒数第二个OFDM符号中发送。本申请不限定具体帧结构以及PSS和SSS在帧结构中的具***置。
(5)、物理小区识别码(physical cell identities,PCI):用于在物理层区分不同小区的无线信号。是在物理层上用于小区间多种信号与信道的随机化干扰的重要参数。
例如,LTE通信***提供504个PCI,网管配置时,网络为小区配置0~503之间的一个号码。504个PCI被分成168个不同的组(记为N
ID
(1),取值范围是0-167),每个组包括3个不同的组内标识(记为N
ID
(2),取值范围是0-2)。
PCI可以以下公式计算得到:PCI=N
ID
cell=3N
ID
(1)+N
ID
(2)。因此,LTE小区搜索流程中可以通过盲检测PSS和SSS来确定具体的PCI。其中,N
ID
(1)和N
ID
(2)的获取方法可以参考上文中的介绍。
(6)、小区搜索:通常,小区搜索的目的在于获取物理小区识别码(identities,ID)以及进行下行同步。例如,对于4G网络和5G网络来说,物理小区ID是指PCI。
下行同步可以包括符号同步、帧同步和频率同步。如上文所述,因为PSS和SSS在帧结构中通常拥有固定的时域位置,所以通过检测PSS和SSS,以及比较两个信号的相对位置就可以获得帧结构的同步,即获取帧同步和符号同步。另外,因为PSS和SSS通常固定占据频带中间固定的子载波(如72个子载波),因此,通过解调PSS和SSS就可以获得中间72个子载波的位置以及中心频点,获取频率同步。
请参考图5,图5以LTE***为例,示出了一种用户识别卡进行下行同步和确定PCI的流程示例图。如图5所示,在确定待检测频点之后,终端设备首先在待检测频点处盲检测PSS。然后,终端设备通过解调PSS,确定PSS在5ms帧中的位置,获得5ms帧同步以及确定当前小区的N
ID
(2)。由于PSS和SSS在帧结构中通常拥有固定的时域位置,因此,接下来,终端设备根据PSS的时域位置检索SSS。然后,终端设备解调SSS,确定PSS和SSS在10ms帧中的相对位置,获得10ms帧同步以及确定当前 小区的N
ID
(1)。最后,终端设备根据确定的N
ID
(1)和N
ID
(2),基于公式PCI=N
ID
cell=3N
ID
(1)+N
ID
(2)计算得到PCI。
需要说明的是,图5所示流程图仅以LTE***中一种用户识别卡进行下行同步和确定PCI的流程作为示例,本申请不限定具体的下行同步及PCI确定方法及流程。关于不同网络制式的具体搜网过程,可以参考常规技术中的介绍。
本申请实施例提供一种多卡模式下的搜网方法,其中,搜网的目的在于搜索到小区。本申请提供的多卡模式下的搜网方法中,终端设备在满足预设条件时,进行搜网流程。在搜网流程中,多个用户识别卡在独立搜网的过程中,可以实时共享各个用户识别卡的搜网进展。例如,第一SIM卡(以下简称SIM卡1)在搜索到小区时可以实时向第二SIM卡(以下简称SIM卡2)发送SIM卡1的搜网信息(即共享信息),以避免SIM卡2浪费搜网资源在相同频点上搜索小区,从而节省时间和资源。
其中,搜网信息可以但不限于搜索到的小区的相关信息和/或已经搜索但未搜索到小区的频点信息。上述预设条件可以包括但不限于终端设备开机或重新上线。
以下以终端设备包括两个实体SIM卡(如SIM卡1和SIM卡2)为例,具体介绍本申请实施例提供的一种多卡模式下的搜网方法。其中,终端设备包括第一SIM卡模块和第二SIM卡模块。第一SIM卡模块中包括SIM卡1,第二SIM卡模块中包括SIM卡2。SIM卡1和SIM卡2所属的运营商相同,即SIM卡1和SIM卡2所属网络的公共陆地移动网络(public land mobile network,PLMN)相同。在终端设备开机后或重新上线后,终端设备的第一SIM卡和第二SIM卡分别独立开始小区搜索。
在一些实施例中,第一SIM卡和第二SIM卡首先在各自的历史频点上搜索小区。其中,若搜网是在开机后进行,则历史频点可以包括终端设备在最近一次关机前,SIM卡所驻留的小区频点。若搜网是在重新上线后进行,则历史频点可以包括终端设备在最近一次掉线前,SIM卡所驻留的小区频点。例如,第一SIM卡的历史频点是第一历史频点,第二SIM卡的历史频点是第二历史频点。
若第一SIM卡在第一历史频点上搜索小区失败,第二SIM卡在第二历史频点上搜索小区失败时,第一SIM卡和第二SIM卡通过本申请实施例提供的一种多卡模式下的搜网方法执行后续搜网流程。
请参考图6,图6是本申请实施例提供的一种多卡模式下的搜网方法的流程示意图。如图6所示,本申请实施例提供的一种多卡模式下的搜网方法可以包括以下步骤S601-S603:
S601、第一SIM卡在第一频段或第一频点上搜索小区,第二SIM卡在第二频段或第二频点上搜索小区。
其中,第一频段或第一频点预置在终端设备中;第二频段或第二频点预置在终端设备中。第一频段或第一频点属于第一制式,第二频段或第二频点属于第一制式或者属于第二制式。例如,第一制式和第二制式可以是GSM、WCDMA、TD-SCDMA、CDMA、LTE(如TDD-LTE或FDD-LTE)或NR等任意网络制式。
示例性的,第一频段和第二频段可以是预置频段中的部分频段。或者,第一频段和第二频段可以是终端设备支持的通信频段中的部分频段。本申请不限定。
在一些实施例中,第一制式与第二制式可以相同。
在另一些实施例中,第一制式与第二制式不同。
S602、第一SIM卡向第二SIM卡发送共享信息。
其中,共享信息可以包括第一搜索信息和/或第二搜索信息。第一搜索信息包括第一SIM卡在第一频段或第一频点上搜索到的小区的小区信息。第二搜索信息包括第一SIM卡在第一频段或第一频点上已搜索但是未搜到小区的频点。
在本申请中,小区信息可以包括但不限于第一SIM卡搜索到的小区的频点(如1857MHz)、物理小区ID(如PCI 490)中的一种或多种。频点信息可以包括但不限于第一SIM卡已搜索但是未搜到小区的频点(如1859Hz)。
在一些实施例中,上述小区信息还可以包括第一SIM卡搜索到的小区所属网络制式(如FDD-LTE),上述频点信息还可以包括第一SIM卡已搜索但是未搜到小区的频点对应的网络制式(如FDD-LTE)。或者,上述共享信息还可以包括其他相关信息,本申请不限定。
需要说明的是,上述小区信息中包括的小区的频点或频点信息中包括的频点还可以用频点号来表示。小区所属网络制式或频点对应的网络制式还可以用网络制式标识信息来表示。例如,用“0”表示FDD-LTE,用“1”表示TDD-LTE等。本申请不限定共享信息中各个具体信息的具体表示形式。
在一些实施例中,第一SIM卡可以在在第一频段或第一频点上搜索到小区(如第一信息)时,向第二SIM卡发送共享信息。其中,共享信息包括第一搜索信息。
在一些实施例中,第一SIM卡可以在在第一频段或第一频点上搜索到小区(如第一信息)时,向第二SIM卡发送共享信息。其中,共享信息包括第一搜索信息和第二搜索信息。
在另一些实施例中,第一SIM卡可以在结束在第一频段或第一频点上的小区搜索时,向第二SIM卡发送共享信息。其中,共享信息包括第二信息。
S603、第二SIM卡根据共享信息跳过在第一频段或第一频点上搜索小区并接入第一小区;或者跳过在第一频段或第一频点上搜索小区,并且在第三频段或第三频点上搜索小区。
其中,第三频段或第三频点预置在终端设备中。第三频段或第三频点属于第一制式、第二制式或者第三制式,本申请不限定。第三制式可以是GSM、WCDMA、TD-SCDMA、CDMA、LTE(如TDD-LTE或FDD-LTE)或NR等任意网络制式,第三制式与第一制式和第二制式不同。
可以理解,因为SIM卡1和SIM卡2位于相同地点,属于相同运营商,因此,第一SIM卡能够搜索到的小区第二SIM卡也大概率可以搜索到。因此,第一SIM卡和第二SIM卡在搜网过程中,通过实时共享各自的搜网进展互作参考,可以很大程度上节省时间和资源。
如上文所述,共享信息可以包括第一搜索信息和/或第二搜索信息。基于此,以下以共享信息的三种情况:情况(1)、情况(2)和情况(3),分别介绍步骤S603的具体实施过程:
情况(1):共享信息包括第一搜索信息。
例如,当第一SIM卡在第一频段或第一频点上搜索到第一小区时,第一SIM卡通 过向第二SIM卡发送第一搜索信息,以用于第二SIM卡根据第一搜索信息跳过在第一频段或第一频点上搜索小区,以及根据第一搜索信息接入第一小区。其中,第一搜索信息包括以下中的一种或多种:第一小区的频点、第一小区的物理小区ID。
对于情况(1),如图7所示,上述步骤S603具体可以包括:第二SIM卡根据第一搜索信息跳过在第一频段或第一频点上搜索小区且接入第一小区。例如,在第一搜索信息包括第一SIM卡搜索到的小区(如第一小区)的物理小区ID时,上述步骤S603具体可以包括:第二SIM卡根据第一搜索信息跳过在第一频段或第一频点上搜索小区,并且接入物理小区ID对应的小区(即第一小区)。
又如,在第一搜索信息包括第一SIM卡搜索到的小区(如第一小区)的频点时,上述步骤S603具体可以包括:第二SIM卡根据第一搜索信息跳过在第一频段或第一频点上搜索小区,且接入上述频点对应的小区(即第一小区)。
在一些实施例中,为了确保第二SIM卡能够顺利接入第一小区,第二SIM卡在接收到第一搜索信息之后,还可以根据第一搜索信息搜索小区,若搜索到第一小区,则接入第一小区。即,上述步骤S603具体可以包括:第二SIM卡根据第一搜索信息搜索第一小区。
例如,在第一搜索信息包括第一SIM卡搜索到的小区(如第一小区)的物理小区ID时,第二SIM卡可以搜索该物理小区ID对应的小区,若搜索到第一小区,则第二SIM卡接入第一小区。
又如。在第一搜索信息包括第一SIM卡搜索到的小区(如第一小区)的频点时,第二SIM卡可以搜索该频点对应的小区,若搜索到第一小区,则第二SIM卡接入第一小区。
情况(2):共享信息包括第二搜索信息。
例如,当第一SIM卡在第一频段或第一频点上搜索小区失败时,第一SIM卡通过向第二SIM卡发送第二搜索信息,以用于第二SIM卡根据第二搜索信息跳过在第一频段或第一频点上搜索小区。其中,第二搜索信息包括第二SIM卡在第一频段或第一频点上已搜索但是未搜到小区的频点。
对于情况(2),如图7所示,上述步骤S603具体可以包括:第二SIM卡根据第二搜索信息跳过在第一频段或第一频点上搜索小区,在第三频段或第三频点上搜索小区。
其中,第三频段或第三频点属于第一制式、第二制式或者第三制式。
在一些实施例中,第二SIM卡根据第二搜索信息跳过在第一频段或第一频点上搜索小区,继续之前的第一制式或者第二制式的搜网,即在第三频段或第三频点上搜索小区。其中,第三频段或第三频点属于第一制式或者第二制式。
在另一些实施例中,第二SIM卡根据第二搜索信息跳过在第一频段或第一频点上搜索小区,在其他制式上搜网,即在第三频段或第三频点上搜索小区。其中,第三频段或第三频点属于第三制式。
在另一些实施例中,第二SIM卡可以根据第二搜索信息调整频点的优先级,以及按照频点优先级在第三频段或第三频点上搜索小区。其中,第三频段或第三频点属于第一制式。第一SIM卡在第一频段或第一频点上已搜索但是未搜到小区的频点优先级 级别为“低”。
需要说明的是,上述优先级级别为“低”仅作为一种示例,这里仅用于说明第二SIM卡将第一SIM卡在第一频段或第一频点上已搜索但是未搜到小区的频点优先级级别设置地较低一些,具体视第二SIM卡设置优先级级别的具体分类而定。例如,上述第一SIM卡已搜索但是未搜到小区的频点优先级级别还可能为“较低”、“最低”等,本申请不限定。
需要说明的是,上述实施例中,第二SIM卡直接使用了第一SIM卡的搜网结果。在一些实施例中,第二SIM卡还可以搜索得到多个小区,以从搜索到的多个小区中,选择最佳的小区驻留。
例如,对于上述情况(1),第二SIM卡还可以将第一搜索信息指示的第一小区作为备选驻留小区。以及,在第三频段或第三频点上搜索小区,以搜索到更多备选驻留小区供选择。其中,第三频段或第三频点属于第一制式、第二制式或者第三制式。
或者,对于共享信息包括第一搜索信息和第二搜索信息的情况,第二SIM卡可以将第一搜索信息指示的第一小区作为备选驻留小区。以及,根据第二搜索信息调整频点的优先级,以及按照频点优先级在第三频段或第三频点上搜索小区,以搜索到更多备选驻留小区供选择。其中,第一SIM卡在第一频段或第一频点上已搜索但是未搜到小区的频点优先级级别为“低”。
需要说明的是,本申请上述实施例是以第一SIM卡向第二SIM卡发送共享信息为例的。第二SIM卡也可以向第一SIM卡发送共享信息,用于第一SIM卡在搜网时作为参考,例如,接入第二SIM卡搜索到的小区或者在第四频段或第四频点上搜索小区,以节省时间和资源。其中,第四频段或第四频点预置在终端设备中。第四频段或第四频点可以属于第一制式、第二制式或第三制式。
如上文所述,通常,在终端设备开机后或重新上线后,终端设备的第一SIM卡和第二SIM卡通常会先在各自的历史频点上搜索小区。例如,如图8、图9、图10、图11、图12或图13所示,第一SIM卡和第二SIM卡分别在第一历史频点和第二历史频点上搜索小区。
在一些实施例中,在第一SIM卡和第二SIM卡分别在各自的历史频点上的搜网过程中,第一SIM卡和第二SIM卡任一方若搜索到小区,也可以实时向另一方发送共享信息,便于另一方可以参考该共享信息进行小区搜索,节省时间和算力。
如图8、图9、图10、图11、图12或图13所示,在历史频点搜网阶段,若第一SIM卡在第一历史频点上搜索到小区,则向第二SIM卡发送第一共享信息,用于第二SIM卡根据该第一共享信息在第一历史频点上搜网。
在一些实施例中,若第一SIM卡和第二SIM卡在历史频点上搜索失败,则第一SIM卡和第二SIM卡再在先验频点上搜索小区。
如图8或图9所示,若第一SIM卡在第一先验频点上搜索到小区,则向第二SIM卡发送第二共享信息,用于第二SIM卡根据该第二共享信息在第一先验频点上搜网。
例如,第一SIM卡可以在第一先验频点上接收信号并计算RSSI,然后按照RSSI由大到小的顺序在对应第一先验频点上搜索小区。第二SIM卡可以在第二先验频点上接收信号并计算RSSI,然后按照RSSI由大到小的顺序在对应第二先验频点上搜索小 区。其中,上述先验频点可以包括终端设备在预设时间段内驻留的小区频点、终端设备在预设时间段内经常驻留的小区的频点等中的一种或多种,本申请不限定,具体可以参考常规技术中对先验频点的介绍和说明。
若第一SIM卡和第二SIM卡在先验频点搜网阶段搜网失败,则第一SIM卡和第二SIM卡按照预设网络制式顺序,逐网络制式搜索小区。例如,第一SIM卡和第二SIM卡按照4G→3G→2G的搜网顺序,逐网络制式搜索小区。其中,上述预设网络制式顺序视终端设备的具体设置而定,不申请不作限定。
在本申请中,第一SIM卡和第二SIM卡的预设网络制式顺序可能一致(即情况A),也可能不一致(即情况B),以下针对这两种情况分别作具体介绍。
对于情况A,如图8所示,在先验频点上搜网失败之后,终端设备的第一SIM卡和第二SIM卡分别按照网络制式A→B的顺序,逐网络制式搜索小区。即,第一SIM卡和第二SIM卡分别先在网络制式A上搜索小区,再在网络制式B上搜索小区。
如图8所示,在网络制式A搜网阶段,若第一SIM卡搜索到小区,则向第二SIM卡发送第三共享信息,用于第二SIM卡根据该第三共享信息在网络制式A上搜网。若第二SIM卡根据第三共享信息在网络制式A上未搜索到小区,则第二SIM卡继续按照预设网络制式顺序,在网络制式B上搜索小区。
如图8所示,若第二SIM卡在网络制式B搜网阶段搜索到小区,则向第一SIM卡发送第四共享信息,用于第一SIM卡根据该第四共享信息在网络制式B上搜网。在图8所示的终端设备的搜网过程中,在任一SIM卡搜索到小区时,该SIM卡便会通知Modem模块进行后续处理,包括解析在对应频点上接收到的***消息、根据***消息解析结果判断是否满足驻留准则,以及在满足驻留准则时驻留在该频点对应的小区。关于上述过程的具体分析过程及判断准则,可以参考常规技术中的介绍,本申请不做赘述。
对于情况B,如图9所示,在先验频点搜网阶段搜网失败之后,终端设备的第一SIM卡按照网络制式A→B的顺序,逐网络制式搜索小区;第二SIM卡按照网络制式B→A的顺序,逐网络制式搜索小区。即,第一SIM卡先在网络制式A上搜索小区,再在网络制式B上搜索小区;第二SIM卡先在网络制式B上搜索小区,再在网络制式A上搜索小区。
如图9所示,若第一SIM卡在网络制式A搜网阶段搜索到小区,则向第二SIM卡发送第三共享信息,第二SIM卡跳过当前的网络制式B搜网阶段,跳转至网络制式A搜网阶段,根据该第三共享信息在网络制式A上搜网。若第二SIM卡根据第三共享信息在网络制式A上未搜索到小区,则第二SIM卡继续跳转回之前的网络制式B搜网阶段,在网络制式B上搜索小区。
如图9所示,若第二SIM卡在网络制式B搜网阶段搜索到小区,则向第一SIM卡发送第四共享信息,用于第一SIM卡根据该第四共享信息在网络制式B上搜网。在图9所示的终端设备的搜网过程中,在任一SIM卡搜索到小区时,该SIM卡便会通知Modem模块进行后续处理,包括解析在对应频点上接收到的***消息、根据***消息解析结果判断是否满足驻留准则,以及在满足驻留准则时驻留在该频点对应的小区。
其中,图8和图9所示的第二SIM卡根据第一共享信息在第一历史频点上搜网、 第二SIM卡根据第二共享信息在第一先验频点上搜网、第二SIM卡根据第三共享信息在网络制式A上搜网,以及第一SIM卡根据第四共享信息在网络制式B上搜网的具体过程视共享信息的具体内容而定,具体可以参考上文中对图7所示的步骤S603的具体介绍。
进一步的,在第一SIM卡和第二SIM卡按照预设网络制式顺序,逐网络制式搜索小区时,具体到每一个网络制式,第一SIM卡和第二SIM卡还可以按照预设频段顺序搜索小区。例如,假设第一SIM卡按照4G→3G→2G的搜网顺序逐网络制式搜索小区,第一SIM卡在4G上搜索小区时,第一SIM卡可以按照预置频段→全频段的预设频段顺序搜索小区。第一SIM卡在3G上搜索小区时,第一SIM卡也按照预置频段→全频段的预设频段顺序搜索小区。在第一SIM卡在2G上搜索小区时,第一SIM卡还是按照预置频段→全频段的预设频段顺序搜索小区。其中,预置频段可以包括网络为终端设备分配的常用频段,或者终端设备在预设时间段内经常驻留的频段,本申请不限定,具体可以参考常规技术中对预置频段的介绍和说明。
请参考图10,图10示出了一种预设网络制式顺序、预设频段顺序的多卡模式下的搜网方法流程图。如图10所示,终端设备的搜网过程主要包括历史频点搜网阶段、先验频点搜网阶段、网络制式A搜网阶段和网络制式B搜网阶段。
具体的,如图10所示,在历史频点搜网阶段,第一SIM卡在第一历史频点上搜索到小区时,向第二SIM卡发送第一共享信息,用于第二SIM卡根据该第一共享信息在第一历史频点上搜网。若第一SIM卡和第二SIM卡在历史频点搜网阶段均未搜索到小区,则第一SIM卡和第二SIM卡进入先验频点搜网阶段。
如图10所示,在先验频点搜网阶段,第一SIM卡在第一先验频点上搜索到小区时,向第二SIM卡发送第二共享信息,用于第二SIM卡根据该第二共享信息在第一先验频点上搜网。若第一SIM卡和第二SIM卡在先验频点搜网阶段均未搜索到小区,则第一SIM卡和第二SIM卡进入网络制式A搜网阶段。
如图10所示,网络制式A搜网阶段包括网络制式A的预置频段搜网阶段和网络制式A的全频段搜网阶段。在网络制式A的预置频段搜网阶段,第一SIM卡在网络制式A的预置频段上搜索到小区时,向第二SIM卡发送第三共享信息,用于第二SIM卡根据该第三共享信息在网络制式A的预置频段上搜网。若第一SIM卡和第二SIM卡在网络制式A的预置频段搜网阶段均未搜索到小区,则第一SIM卡和第二SIM卡进入网络制式A的全频段搜网阶段。
如图10所示,在网络制式A的全频段搜网阶段,第二SIM卡在网络制式A的全频段上搜索到小区时,向第一SIM卡发送第四共享信息,用于第一SIM卡根据该第四共享信息在网络制式A的全频段上搜网。若第一SIM卡和第二SIM卡在网络制式A的全频段搜网阶段均未搜索到小区,则第一SIM卡和第二SIM卡进入网络制式B的搜网阶段。
如图10所示,网络制式B搜网阶段包括网络制式B的预置频段搜网阶段和网络制式B的全频段搜网阶段。在网络制式B的预置频段搜网阶段,第二SIM卡在网络制式B的预置频段上搜索到小区时,向第一SIM卡发送第五共享信息,用于第一SIM卡根据该第五共享信息在网络制式B的预置频段上搜网。若第一SIM卡和第二SIM 卡在网络制式B的预置频段搜网阶段均未搜索到小区,则第一SIM卡和第二SIM卡进入网络制式B的全频段搜网阶段。
如图10所示,在网络制式B的全频段搜网阶段,第二SIM卡在网络制式B的全频段上搜索到小区时,向第一SIM卡发送第六共享信息,用于第一SIM卡根据该第六共享信息在网络制式B的全频段上搜网。在图10所示的终端设备的搜网过程中,在任一SIM卡搜索到小区时,该SIM卡便会通知Modem模块进行后续处理,包括解析在对应频点上接收到的***消息、根据***消息解析结果判断是否满足驻留准则,以及在满足驻留准则时驻留在该频点对应的小区。
需要说明的是,图10是以第一SIM卡和第二SIM卡的预设网络制式顺序(即上述情况A)作为示例,具体介绍终端设备的搜网过程。对于第一SIM卡和第二SIM卡的预设网络制式顺序不一致的情况(即上述情况B),也可以采用图11类似的预设频段顺序完成每一个网络制式对应的小区搜索。
另外,图10是以第一SIM卡和第二SIM卡的每一个网络制式对应的预设频段顺序一致作为示例,具体介绍终端设备的搜网过程。本申请提供的多卡模式下的搜网方法对于不同网络制式对应的预设频段顺序不一致的情况,或者第一SIM卡和第二SIM卡在同一网络制式中对应的预设频段顺序不一致的情况也适用。
在另一些实施例中,若第一SIM卡和第二SIM卡在历史频点上搜索失败,则第一SIM卡和第二SIM卡还可以分别在为其服务的运营商的全频段上搜索小区。若搜索失败,则再在终端设备支持的全频段上搜索小区。
在搜网过程中,第一SIM卡和第二SIM卡任一方若搜索到小区,便实时向另一方发送共享信息,便于另一方可以参考该共享信息进行小区搜索,节省时间和算力。
如图11所示,在第一SIM卡和第二SIM卡在历史频点上搜索失败后,第一SIM卡和第二SIM卡分别在为其服务的运营商的全频段上搜索小区。若第一SIM卡在运营商的全频段搜网阶段搜索到小区,则向第二SIM卡发送第二共享信息,用于第二SIM卡根据该第二共享信息在运营商的全频段上搜索小区。若第一SIM卡在运营商的全频段上未搜索到小区,则第一SIM卡继续在终端设备支持的全频段上搜索小区。
如图11所示,若第一SIM卡在终端设备支持的全频段搜网阶段搜索到小区,则向第二SIM卡发送第三共享信息,用于第二SIM卡根据该第三共享信息在终端设备支持的全频段上搜索小区。在图11所示的终端设备的搜网过程中,在任一SIM卡搜索到小区时,该SIM卡便会通知Modem模块进行后续处理,包括解析在对应频点上接收到的***消息、根据***消息解析结果判断是否满足驻留准则,以及在满足驻留准则时驻留在该频点对应的小区。
在另一些实施例中,若第一SIM卡和第二SIM卡在历史频点上搜索失败,则第一SIM卡和第二SIM卡可以按照modem模块指定的搜索任务,分别搜索小区。
如图12或图13所示,在第一SIM卡和第二SIM卡在历史频点上搜索失败后,modem模块分别向第一SIM卡和第二SIM卡发送第一任务信息和第二任务信息,用于第一SIM卡和第二SIM卡分别按照第一任务信息和第二任务信息搜索小区。
其中,第一任务信息和第二任务信息可以分别指示不同网络制式的搜索任务,或者,第一任务信息和第二任务信息还可以分别指示同一网络制式不同频段上的搜索任 务,本申请对此不限定。
假设第一任务信息和第二任务信息分别指示不同网络制式的搜索任务,更为具体的,第一任务信息指示网络制式A的搜索任务,第二任务信息指示网络制式B的搜索任务。如图12所示,若第一SIM卡在网络制式A搜网阶段搜索到小区,则向第二SIM卡发送第二共享信息,用于第二SIM卡根据该第二共享信息在网络制式A上搜索小区。若第二SIM卡在网络制式B搜网阶段搜索到小区,则向第一SIM卡发送第三共享信息,用于第一SIM卡根据该第三共享信息在网络制式B上搜索小区。在图12所示的终端设备的搜网过程中,在任一SIM卡搜索到小区时,该SIM卡便会通知Modem模块进行后续处理,包括解析在对应频点上接收到的***消息、根据***消息解析结果判断是否满足驻留准则,以及在满足驻留准则时驻留在该频点对应的小区。
假设第一任务信息和第二任务信息分别指示同一网络制式不同频段上的搜索任务,更为具体的,第一任务信息指示网络制式A的频段a的搜索任务,第二任务信息指示网络制式A的频段b的搜索任务。如图13所示,若第一SIM卡在网络制式A的频段a搜索到小区,则向第二SIM卡发送第二共享信息,用于第二SIM卡根据该第二共享信息在网络制式A的频段a上搜索小区。若第二SIM卡在网络制式A的频段b搜索到小区,则向第一SIM卡发送第三共享信息,用于第一SIM卡根据该第三共享信息在网络制式A的频段b上搜索小区。在图13所示的终端设备的搜网过程中,在任一SIM卡搜索到小区时,该SIM卡便会通知Modem模块进行后续处理,包括解析在对应频点上接收到的***消息、根据***消息解析结果判断是否满足驻留准则,以及在满足驻留准则时驻留在该频点对应的小区。
