从3G、4G到5G,手机上网的速度越来越快。但对于电信运营商来说,因为所使用的频段越来越高,而带来网络覆盖难度的增加,是不得不面对的难题。尤其是室内深度覆盖,难度更高,会给用户在室内数据上网和语音通话带来不便。WiFi被视为打开“门锁”的“钥匙”,只要室内有WiFi,即使移动信号覆盖不佳,上网也可以轻易实现,而且WiFi也能满足室内场景下语音通话的需求。
在国外,VoWiFi(Voice over WiFi,无线通话或WiFi通话)或者称WiFi Calling业务多年前已经普及。随着5G时代的到来,VoWiFi业务有望助力解决室内通话难题。
近日,某移动公司推出了“WiFi通话助手”应用,按照官方对这款应用的介绍,“有WiFi即可通话”。实际上,VoWiFi在国内并非新鲜事物,多年前运营商就开展研发手机原生支持VoWiFi的研究,App版本的VoWiFi业务也曾出现过。在四年前举行的一次国内通信行业盛会上,一家国内电信运营商现场展示了VoWiFi业务,而且实现了VoLTE(Voice over Long-Term Evolution,长期演进语音承载)和VoWiFi之间的双向无缝切换。也就是说,用户在通话状态下,可根据移动网络和WiFi网络的信号强弱情况,由手机自动选择切入信号更佳的网络,向用户提供VoLTE通话或者VoWiFi通话服务,切换前后通话不会中断。
VoLTE/VoWiFi这项技术已经挺成熟,VoNR(Voice over NR,NR,New Radio,新空口,手机和基站通信的一个接口)也即将到来,但是因为其他一些因素,VoWiFi并没有推广应用。如果当时能推广,对‘拯救’运营商的语音业务还是很有 帮助的。现在是通信4.0时代,实际上在3.0时代,所有语音承载在IP网上就是大趋势。VoWiFi还是会起来的,其实这也是RCS(融合通信)的一种。现在5G时代来了,室内覆盖难度更高,VoWiFi可以发挥更大作用,帮助解决语音通话难题。
例如在美国,AT&T、Verizon、T-Mobile这些运营商多年前已经推出VoWiFi业务,颇为普及。而在印度,去年底今年初,终端厂商看到主流运营商的新动向,印度手机市场的主流厂商也纷纷行动起来,包括华为、OPPO、诺基亚、三星等等,纷纷发布软件更新计划,让自己的手机支持VoWiFi功能,来满足运营商和用户的需求。比如就在6月中旬,OPPO在印度市场推出ColorOS系统也支持VoWiFi。最近起了推广VoWiFi的热潮。
从全球范围内来看,VoWiFi正在快速发展。市场调研机构Mordor Intelligence发布报告称,预计VoWiFi市场规模从2019年的19.2亿美元增长到2025年的81.7亿美元,复合年增长率为27.24%。大多数运营商将会同时推出VoWiFi和VoLTE服务,后续如果网络支持VoNR,还将支持VoWiFi和VoNR服务,从而有效改善室内网络覆盖,推动向全IP通信的演进。
总体来说,VoWiFi对运营商是有利的。一方面,虽然语音业务收入在下滑,但是用户对于语音通信需求是刚性、必需的,语音通话体验差将会加大用户流失,而VoWiFi可以帮助运营商解决蜂窝网络室内覆盖差这一大难题,提升用户语音通话体验。同时,现在大城市普遍家庭用户都拥有百兆或者千兆以上宽带,借助用户家中、办公场所内的WiFi,还有数量庞大的公共WiFi网络提供WiFi通话服务,可以帮助降低运营商蜂窝网络的负荷,有助于释放频谱资源。
目前,VoLTE/VoNR和VoWiFi的切换方案考虑的切换条件都比较简单,一般只根据阈值(Threshold)和定时器(Timer)来判断是否需要切换,但是这个Threshold只是一个固定的值,这很容易导致ping pong切换(ping pong是一种数据缓存的手段,通过ping pong操作可以提高数据传输的效率)。另外这种切换方案只适合Wi-Fi和LTE/NR边缘移动的切换场景,因为当从LT/NR差信号进入WiFi覆盖良好的区域时,才会切换到WiFi。如果用户通话优选设置的是移动网络优先,当LTE/NR信号一般的情况下,但是WiFi信号很好的情况下,并不能触发切换到WiFi通话,这样就起不到降低运营商蜂窝网络的负荷的作用。但是 如果WiFi信号很好,网络传输时延较大,因为带宽、业务量或者网络拥塞等因素影响,也可能信号好的时候信号传输的速率不佳,也会影响到VoWi-Fi通话质量。

具体实施方式
为使本公开的目的、技术方案及优点更加清楚、明确,以下参照附图并举实施例对本公开进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本公开,并不用于限定本公开。
目前,VoLTE/VoNR和VoWiFi的切换方案考虑的切换条件都比较简单,一般只根据阈值(Threshold)和定时器(Timer)来判断是否需要切换,但是这个Threshold只是一个固定的值,这很容易导致ping pong切换(ping pong是一种数据缓存的手段,通过ping pong操作可以提高数据传输的效率)。另外这种切换方案只适合Wi-Fi和LTE/NR边缘移动的切换场景,因为当从LT/NR差信号进入WiFi覆盖良好的区域时,才会切换到WiFi。如果用户通话优选设置的是移动网络优先,当LTE/NR信号一般的情况下,但是WiFi信号很好的情况下,并不能触发切换到WiFi通话,这样就起不到降低运营商蜂窝网络的负荷的作用。但是如果WiFi信号很好,网络传输时延较大,因为带宽、业务量或者网络拥塞等因素影响,也可能信号好的时候信号传输的速率不佳,也会影响到VoWi-Fi通话质量。
因此,针对现有技术的上述缺陷,本公开较佳实施例所述的网络通话切换方 法,如图1所示,所述网络通话切换方法包括以下步骤:
步骤S10、当移动终端进行语音通话时,检测并判断用户当前的优选设置,所述优选设置包括移动网络优先和WiFi网络优先。
具体过程请参阅图2,其为本公开提供的网络通话切换方法中步骤S10的流程图。
如图2所示,所述步骤S10包括:
S11、所述移动终端接收操作指令,开启语音通话功能;
S12、所述移动终端检测用户当前对语音通话的优选设置,判断优选设置为移动网络优先还是WiFi网络优先。
具体地,为了更好的判断是否进行通话网络的切换,在所述步骤S10之前还包括:所述移动终端预先设置一用于判断是否将VoLTE或者VoNR通话切换到VoWi-Fi通话的第一预设信号阈值,所述第一预设信号阈值表示当前VoWiFi网络的信号强;以及所述移动终端预先设置一用于判断是否将VoWiFi通切换到VoLTE或者VoNR通话的第二预设信号阈值,所述第二预设信号阈值表示当前VoLTE或者VoNR网络的信号强。通过设置这两个条件,只有当VoLTE或者VoNR网络、以及VoWiFi网络的信号值达到一定强度时,才能进行通话网络的切换,以减少一搜到某个网络切换的情况,保证了通话的质量不受影响,给用户的使用带来了方便。
所述移动终端接收操作指令,开启语音通话功能(例如IMS语音通话),所述移动终端检测用户当前对语音通话的优选设置,即判断所述优选设置为移动网络优先还是WiFi网络优先;其中,所述移动网络优先表示所述移动终端进行语音通话时的默认选择网络通话为VoLTE或者VoNR通话,所述WiFi网络优先表示所述移动终端进行语音通话时的默认选择网络通话为VoWiFi通话。
另外,所述第一预设信号阈值小于所述第二预设信号阈值,所述第一预设信号阈值的取值范围为-115dBm至-100dBm,例如取值为-115dBm、-110dBm、-105dBm、-100dBm,所述第二预设信号阈值取值范围为-85dBm至-70dBm,例如取值为-85dBm、-80dBm、-75dBm、-70dBm。
步骤S20、如果所述优先设置为所述移动网络优先,检查移动网络信号是否低于第一预设信号阈值,若是,则将VoLTE或者VoNR通话切换到VoWiFi通话。
具体过程请参阅图3,其为本公开提供的网络通话切换方法中步骤S20的流程图。
如图3所示,所述步骤S20包括:
S21、当所述移动终端识别出当前语音通话的所述优先设置为所述移动网络优先时,获取所述移动终端当前的移动网络信号;
S22、所述移动终端判断所述移动网络信号是否低于预先设置的所述第一预设信号阈值;
S23、若所述移动网络信号低于所述第一预设信号阈值,则将所述移动终端当前语音通话所使用的VoLTE或者VoNR通话切换到VoWiFi通话。
具体地,当所述移动终端识别出当前语音通话的所述优先设置为所述移动网络优先时,即所述移动网络优先表示所述移动终端进行语音通话时的默认选择网络通话为VoLTE或者VoNR通话,获取所述移动终端当前的移动网络信号,所述移动终端判断所述移动网络信号是否低于预先设置的所述第一预设信号阈值,所述移动网络信号低于预先设置的所述第一预设信号阈值的话表示当前VoLTE或者VoNR通话的质量不佳,因此,若所述移动网络信号低于所述第一预设信号阈值(例如移动网络信号低于-115dBm),则将所述移动终端当前语音通话所使用的VoLTE或者VoNR通话切换到VoWiFi通话,这样可以保证用户在网络质量最优的网络上进行通话,可以提高通话质量,减少通话时延,减少掉话率以及接通率。
若所述移动网络信号低于所述第一预设信号阈值,则此时VoWiFi网络信号强度较佳,可以将VoLTE或者VoNR通话切换至VoWiFi通话,不但不会影响通话质量,而且使用VoWiFi网络通话质量更加好,给用户更好的体验。如果当前所述移动网络信号大于所述第一预设信号阈值,则说明当前VoWiFi网络强度不够,则不进行切换,并再次获取当前移动网络信号并与所述第一预设信号阈值比较,直到所述移动网络信号低于所述第一预设信号阈值时,才进行通话网络的切换。
步骤S30、如果所述优先设置为所述WiFi网络优先,检查WiFi网络信号是否低于第二预设信号阈值,若是,则将VoWiFi通话切换到VoLTE或者VoNR通话。
具体过程请参阅图4,其为本公开提供的网络通话切换方法中步骤S30的流程图。
如图4所示,所述步骤S30包括:
S31、当所述移动终端识别出当前语音通话的所述优先设置为所述WiFi网络优先时,获取所述移动终端当前的WiFi网络信号;
S32、所述移动终端判断所述WiFi网络信号是否低于预先设置的所述第二预设信号阈值;
S33、若所述WiFi网络信号低于所述第二预设信号阈值,则将所述移动终端当前语音通话所使用的VoWiFi通话切换到VoLTE或者VoNR通话。
具体地,当所述移动终端识别出当前语音通话的所述优先设置为所述WiFi网络优先时,即所述WiFi网络优先表示所述移动终端进行语音通话时的默认选择网络通话为VoWiFi通话,获取所述移动终端当前的WiFi网络信号,所述移动终端判断所述WiFi网络信号是否低于预先设置的所述第二预设信号阈值,所述WiFi网络信号低于预先设置的所述第二预设信号阈值的话表示当前VoWiFi通话的质量不佳,因此,若所述WiFi网络信号低于所述第二预设信号阈值(例如WiFi网络信号低于-85dBm),则将所述移动终端当前语音通话所使用的VoWiFi通话切换到VoLTE或者VoNR通话,这样可以保证用户在网络质量最优的网络上进行通话,可以提高通话质量,减少通话时延,减少掉话率以及接通率。
若所述WiFi网络信号低于第二预设信号阈值,则此时VoLTE或者VoNR网络信号强度较佳,可以将VoWiFi通话切换至VoLTE或者VoNR通话切换,不但不会影响通话质量,而且使用VoLTE或者VoNR网络通话质量更加好,给用户更好的体验。如果当前WiFi网络信号大于第二预设信号阈值,则说明当前VoLTE或者VoNR网络强度不够,则不进行切换,并再次获取当前WiFi网络信号并与所述第二预设信号阈值比较,直到所述WiFi网络信号低于所述第二预设信号阈值时,才进行通话网络的切换。
进一步地,如果WiFi网络信号很好,但是网络传输时延较大,因为带宽、业务量或者网络拥塞等因素影响,也可能信号好的时候信号传输的速率不佳,也会影响到VoWiFi通话质量,这时候也优先选择VoLTE或者VoNR通话。
本公开根据网络信号来切换通话方式,满足移动网络和WiFi网络信号的检 测,并更好的判断当前WiFi信号质量,如果信号较好,就可以起到更多的分流作用,减少运营商网络负荷,另一方面,该方案结合通话状态和通话优选的设置,更好的选择通话质量更佳的网络,也可以减少通话质量问题发生的概率。
进一步地,基于上述网络通话切换方法,如图5所示,本公开还提供一种网络通话切换系统,其中,所述网络通话切换系统包括:
检测判断模块100,用于当移动终端进行语音通话时,检测并判断用户当前的优选设置,所述优选设置包括移动网络优先和WiFi网络优先;
