Description

用户设备切换基站的方法和网元设备

在5G及下一代,移动网络服务的对象不再是单纯的手机,而是各种类型的用户设备(User Equipment,UE),如平板电脑、移动车辆和各种传感器等。移动网络服务的场景也多样化,比如移动宽带、大规模机器类型通信、任务关键型互联网等。因此,在移动性、安全性、时延性和可靠性等多个方面,移动网络都必须满足更高的要求。
移动边缘计算(Mobile Edge Computing,MEC)是5G及下一代移动通信系统提升服务能力的重要技术手段之一。MEC可以将传统集中式数据中心里的云计算平台与移动网络融合,具体地,可以在无线接入网(Radio Access Network,RAN)侧部署通用服务器(即,MEC服务器),将原本位于云数据中心中的服务和功能“下沉”到移动网络的边缘,在移动网络边缘就近提供计算、存储、网络和通信资源,以保证用户服务质量(Quality of Service,QoS)和服务体验(Quality of Experience,QoE)。
当UE移动到服务小区的边缘,需要及时切换到另一个邻区上,以获得移动网络持续不断的服务。现有技术中,服务小区对应的服务基站通常是根据邻区的信号质量,指示UE切换到信号质量优于服务小区的邻区所对应的目标基站。然而,这种切换基站的方法,可能导致UE切换至目标基站后,无法满足UE的业务需求。例如,UE在切换基站的过程中,获得相应服务所需的时间变长,或者导致业务间断。

如图1所示,用户在使用UE的过程中,用户的位置可能会发生变化。当UE移动到服务小区的边缘(例如,UE移动到服务小区与邻区1的信号重叠区域)时,需要及时换到邻区上,以获得移动网络持续不断的服务。
现有技术中,服务小区对应的服务基站通常是根据邻区的信号质量,指示UE切换到信号质量优于服务小区的邻区所对应的目标基站。目标基站对应的MEC服务器与服务基站对应的MEC服务器可能相同,也可能不同。
当目标基站对应的MEC服务器与服务基站对应的MEC服务器相同时,UE在同一个MEC服务器范围内移动,MEC服务器只需要维持UE与MEC服务器上应用程序的正常连接,同时跟踪UE当前连接的基站来确保正确的下行数据路由即可。UE在同一MEC服务器下的移动时,服务基站与目标基站的通信能力可能不同。
当目标基站对应的MEC服务器与服务基站对应的MEC服务器不同时,UE从一个MEC服务器切换到另一个MEC服务器上,如何保持UE与应用间的业务连接将是一个难点。对于MEC系统中那些不需要跟踪UE状态信息的状态独立的应用来说,UE移动到另一个MEC服务器意味着重新在该MEC服务器上实例化一个相同的应用(即,在UE与MEC服务器建立通信连接之后,UE将正在运行的应用的业务切换至该MEC服务器,并对该应用进行初始化),而对于面向用户的服务,特别是那些与用户活动相关的应用而言,UE移动到另一个MEC服务器将意味着用户相关信息的迁移,甚至是整个应用实例的迁移。当目标基站对应的MEC服务器与服务基站对应的MEC服务器不同时,服务基站与目标基站的通信能力、计算能力和存储能力可能均不同。
总的来说,由于在MEC下,不同基站的通信能力、计算能力和存储能力也可能不同。而不同类型的UE,其通信能力、计算能力和存储能力可能不同,因此,UE切换至目标基站后,可能因无法满足UE的通信能力、计算能力和存储能力的需求,而导致目标基站无法满足UE的业务需求,目前这种传统的依赖信号质量进行基站切换的方法不适合于5G及下一代移动网络。
例如,当目标基站与服务基站所对应的MEC服务器不同时,为了保持UE与应用间的业务连接,需要在目标基站对应的MEC服务器上重新实例化一个相同的应用,或迁移整个应用实例,可能导致用户获得该应用对应的服务所需的时间变长,甚至可能出现网络 中断或掉线等情况发生。
为了解决现有技术中,UE切换基站后,该无法满足UE的能力需求的问题,本申请实施例提供了一种用户设备切换基站的方法,服务基站接收UE上报的测量报告以及能力需求信息,例如,计算能力需求和通信能力需求信息等;服务基站根据测量报告中的相关数据确认UE需要切换基站时,发送携带UE的能力需求信息的切换请求信息至邻区基站;邻区基站根据切换请求信息中的能力需求信息判断是否满足UE的能力需求,得到判断结果,并发送切换请求响应信息至服务基站,切换请求响应信息包括该判断结果以及邻区基站的能力信息;服务基站根据邻区基站发送的切换请求响应信息中的判断结果,筛选出满足UE能力需求的目标邻区基站。服务基站可以根据目标邻区基站的能力信息,从目标邻区基站中确定与UE的能力需求信息匹配度较高的目标基站,并发送包含目标基站的标识信息的切换命令至UE,以指示UE从服务基站切换到目标基站。邻区基站的能力信息与UE的能力需求信息越接近或相近,邻区基站的能力信息与UE的能力需求信息之间的匹配度越高。或者,可以根据每个目标邻区基站的能力信息以及UE的能力需求信息,计算目标邻区基站的能力得分,能力得分越高,邻区基站的能力信息与UE的能力需求信息之间的匹配的越高。
在一种可能的实现方式中,目标基站可以由UE来确定。
例如,服务基站接收到邻区基站发送的切换请求响应信息后,可以通过切换命令将切换请求响应信息中包括的判断结果以及邻区基站的能力信息发送至UE,以使得UE根据该判定结果以及邻区基站的能力信息,确定与UE的能力需求信息匹配度较高的目标基站,并切换至该目标基站。
再例如,服务基站可以在筛选出满足UE能力需求的目标邻区基站之后,发送包括目标邻区基站的能力信息的切换命令至UE,以使得UE能够根据目标邻区基站的能力信息,筛选出与UE的能力需求信息匹配度高的目标基站,从而从服务基站切换至目标基站。
可以理解的是,测量报告可以包括邻区基站的信号质量信息,服务基站或UE,可以从满足UE的能力需求的目标邻区基站中,选择信号质量最好的邻区基站作为目标基站。
另外,邻区基站发送的切换请求响应信息中还可以包括移动边缘计算(Mobile Edge Computing,MEC)服务器的标识。
当目标基站由服务基站确定时,可以根据目标邻区基站的MEC服务器的标识以及服务基站的MEC服务器的标识,从满足UE能力的目标邻区基站中,确定与服务基站属于同一个MEC服务器的目标邻区基站。如果确定的目标邻区基站为一个,那么将该目标邻区基站作为目标基站。如果确定的目标邻区基站为至少两个,可以从该至少两个目标邻区基站中,选择与UE的能力需求匹配度最高的目标邻区基站作为目标基站;或者选择信号质量最好的目标邻区基站作为目标基站。
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请的用户设备切换基站的方法的具体实现过程作进一步地详细描述。
请参见图2,图2是本申请实施例提供的一种用户设备切换基站的方法的交互图。用户设备UE包括但不限于手机、平板电脑、可穿戴设备、移动车辆、各种传感器等可接入无线移动网络的终端。UE在移动到已接入的服务基站对应的服务小区的边缘时,UE需要切换至邻区基站,以获得移动网络持续不断的服务。用户设备切换基站的方法包括以下步 骤:
S101、UE发送能力需求信息至服务基站。
UE可以在发起业务请求时,上报能力需求信息至服务基站,也可以在UE的能力需求发生变化时,上报能力需求信息至服务基站。
能力需求信息至少包括通信能力需求信息以及计算能力需求信息。通信能力需求信息可以包括但不限于传输速率、传输时延、丢包率、误码率中的其中一个或至少两个的任意组合。计算能力需求信息包括但不限于每秒运算次数或每秒操作次数。
其中,传输速率越高,表示通信能力需求越高;传输时延越低、丢包率越低或误码率越低,表示通信能力需求越高。每秒运算次数或每秒操作次数越高,计算能力需求越高。
在本实施例中,UE向服务基站上报能力需求信息的方式不做限制。UE可以通过无线资源控制(Radio Resource Control,RRC)信令上报能力需求信息,此时,能力需求信息承载于RRC信令中。UE也可以通过媒体介入控制-控制元素(Media Access Control-Control Element,MAC CE)信令发送能力需求信息,此时,能力需求信息承载于MAC CE信令中。UE还可以将能力需求信息与其他待传输的数据一起发送至服务基站。能力需求信息可以处于待传输数据之前或之后,还可以处于待传输数据中,即,将能力需求信息插入待传输数据中后发送。例如,S101中的能力需求信息可以与S105中的测量报告一起发送至服务基站。
在一种可能的实现方式中,能力需求信息还可以包括存储能力需求信息。通信能力需求信息的优先级以及计算能力需求信息的优先级,均高于存储能力需求信息的优先级。即,邻区基站需要优先满足UE的通信能力需求,和/或,UE的计算能力需求,最后再考虑UE的存储能力需求。
在一种可能的实现方式中,能力需求信息可以由UE在接收到用户触发的业务请求时而发送。能力需求信息可以为在一段时长内用户发起的业务所对应的能力需求信息,能力需求信息可以取一段时长内的均值,也可以取能力需求最大值,此处不做限制。
可以理解的是,当用户发起至少两个业务,且至少两个业务各自对应的能力需求不同时,UE上报的能力需求信息以能力需求高的为准。例如,当第一业务的通信能力需求高于第二业务的能力需求时,UE上报的能力需求信息中的通信能力需求信息为第一业务对应的通信能力需求信息。当第二业务的计算能力需求高于第一业务的计算能力需求时,UE上报的能力需求信息中的计算能力需求信息为第二业务对应的计算能力需求信息。
S102、服务基站获取UE发送的能力需求信息。
S103、服务基站发送测量配置信息至UE。
测量配置信息可以包括测量对象的信息,例如,待测量的邻区基站的频点、制式、该频点上的小区列表等信息。测量配置信息用于指示UE测量服务基站对应的服务小区,以及邻区基站对应的邻区的信号质量。
信号质量可以是以下一种或至少两种的任意组合:参考信号接收功率(Reference Signal Receiving Power,RSRP)、参考信号接收质量(Reference Signal Receiving Quality,RSRQ)以及信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)。
可以理解的是,S103可以在S101或S102之前执行。
S104、UE接收服务基站发送的测量配置信息,根据测量配置信息进行测量,发送测 量报告至服务基站。
UE在接收到服务基站发送的测量配置信息之后,可以测量UE已接入的服务小区的信号质量,还可以根据测量配置信息中的测量对象的信息,切换至邻区基站对应的待测频点,从而对邻区基站对应的邻区进行测量,以得到邻区基站所管理的各邻区所对应的信号质量。
UE在完成测量时,根据测量结果生成测量报告,并发送测量报告至服务基站。测量报告中包括服务小区的信号质量以及邻区基站所管理的各邻区所对应的信号质量。
S105、服务基站获取UE发送的测量报告。
S106、服务基站根据所述测量报告判断是否满足基站切换条件。
服务基站根据测量报告中服务小区的信号质量以及邻区的信号质量,执行切换判决,以判断是否满足基站切换条件。基站切换条件可以是预先设置并存储于服务基站中,用于表示UE切换基站需要满足的条件。例如,基站切换条件可以是服务小区的信号质量小于第一信号质量阈值,邻区的信号质量大于第二信号质量阈值。第二信号质量阈值可以大于第一信号质量阈值。
S107、服务基站在确认满足所述基站切换条件时,发送切换请求信息至邻区基站,所述切换请求信息包括所述能力需求信息。
切换请求用于指示邻区基站判断是否满足UE的能力需求,以及是否允许UE接入邻区基站。邻区基站的数量可以为至少两个。
S108、邻区基站获取服务基站发送的切换请求信息。
S109、邻区基站响应于所述切换请求信息,根据所述能力需求信息以及所述邻区基站的能力信息,判断是否满足所述UE的能力需求。
邻区基站可以将UE的能力需求信息以及邻区基站自己的能力信息进行比较,根据比较结果判断邻区基站是否能够满足UE的能力需求。当邻区基站的能力能够满足UE的能力需求信息所对应的各项能力需求时,邻区基站可以满足UE的能力需求。当邻区基站的能力无法满足UE的能力需求信息所对应的任一项能力需求时,邻区基站不能满足UE的能力需求。
例如,当能力需求信息包括通信能力需求信息以及计算能力需求信息时,可以比较UE的能力需求信息中的通信能力需求信息以及邻区基站的通信能力,从而判断邻区基站是否满足UE的通信能力需求;比较UE的能力需求信息中的计算能力需求信息以及邻区基站的计算能力,从而判断邻区基站是否满足UE的计算能力需求。
当UE的能力需求信息中的通信能力需求信息包含传输速率,计算能力需求信息包括每秒运算次数时,假设,UE的能力需求信息中的传输速率为a 1Mbit/s,每秒运算次数为a 2;邻区基站的传输速率为b 1Mbit/s,每秒运算次数为b 2;如果a 1<=b 1,且a 2<=b 2,那么邻区基站能够满足UE的通信能力需求;如果a 1>b 1,或,a 2>b 2,那么邻区基站无法满足UE的通信能力需求。
邻区基站还可以根据邻区基站的负载能力判断是否允许UE接入。负载能力可以是允许接入的UE的最大值,也可以是通信负载最大功率,此处不做限制。
S110、邻区基站发送切换请求响应信息至所述服务基站,所述切换请求响应信息至少包括能力指示标识以及邻区基站的能力信息,所述能力指示标识用于表示所述邻区基站是 否满足所述能力需求信息。
能力指示标识用于服务基站或UE从邻区基站中筛选出能够满足UE的能力需求的目标邻区基站。即,目标邻区基站是邻区基站中满足能力需求信息的邻区基站。邻区基站的能力信息用于计算目标邻区基站与UE之间的匹配度,并根据匹配度从目标邻区基站中确定目标基站。
可以理解的是,切换请求响应信息中的能力指示标识可以用于“0”或“1”来表示。当邻区基站无法满足UE的能力需求,或者邻区基站不允许UE接入时,切换请求响应信息中的能力指示标识为“0”。当邻区基站能够满足UE的能力需求,且邻区基站允许UE接入时,切换请求响应信息中的能力指示标识为“1”。
可以理解的是,每个邻区基站发送的切换请求响应信息中的能力信息,其能力类型和数量均相同。例如,所有的邻区基站发送的切换请求响应信息中的能力信息均包括通信能力以及计算能力,或者,均包括通信能力、计算能力以及存储能力。
其中,当切换请求信息中的能力需求信息中包括通信能力需求以及计算能力需求时,切换请求响应信息中包含的邻区基站的能力信息可以包括通信能力以及计算能力,当切换请求信息中的能力需求信息还包括存储能力需求信息时,切换请求响应信息中还可以包括邻区基站的存储能力。
可以理解的是,切换请求响应信息可以携带邻区基站的标识信息。
S111、服务基站获取所述切换请求响应信息,切换请求响应信息包括能力指示标识以及发送切换请求信息的邻区基站的能力信息。
可以理解的是,服务基站在接收到邻区基站发送的切换请求响应信息时,可以关联记录切换请求响应信息以及邻区基站的标识信息,以便后续能够准确获悉邻区基站的能力信息。
S112、服务基站根据所述切换请求响应信息中的能力指示标识,确定满足所述能力需求信息的目标邻区基站。
服务基站对切换请求响应信息进行解析,获取切换请求响应信息中的能力指示标识以及邻区基站的能力信息。当切换请求响应信息还携带邻区基站的标识信息时,服务基站还可以获取到邻区基站的标识信息。
服务基站根据能力指示标识,从发送切换请求响应信息的邻区基站中,确定满足UE的能力需求的目标邻区基站。
例如,当能力指示标识用“0”或“1”来表示时,服务基站筛选出能力指示标识为“1”对应的邻区基站,将其作为目标基站,并将与能力指示标识为“1”关联的邻区基站的能力信息,识别为目标邻区基站的能力信息。
S113、服务基站根据所述能力需求信息以及所述目标邻区基站的能力信息,从所述目标邻区基站中确定目标基站,所述目标基站为所述邻区基站中满足所述能力需求信息的基站。
服务基站在筛选出满足UE的能力需求的目标邻区基站之后,获取目标邻区基站的能力信息。
然后,服务基站根据每个目标邻区基站的能力信息以及UE的能力需求信息,计算目标邻区基站的能力信息与UE的能力需求信息之间的匹配度,得到每个目标邻区基站与 UE之间的匹配度;之后,根据所有目标邻区基站对应的匹配度,筛选出匹配度符合预设要求的目标邻区基站,并从筛选出的目标邻区基站中确定目标基站。其中,预设要求可以是匹配度大于或等于预设匹配度阈值。邻区基站的能力信息与UE的能力需求信息越接近或相近,邻区基站的能力信息与UE的能力需求信息之间的匹配度越高,即,邻区基站与UE之间的匹配度越高。或者,可以根据每个目标邻区基站的能力信息以及UE的能力需求信息,计算目标邻区基站的能力得分,能力得分越高,邻区基站与UE之间的匹配的越高。服务基站可以将匹配度最高的目标邻区基站作为目标基站。例如,当能力需求信息中包括通信能力需求信息时,服务基站可以将通信匹配度最高的目标邻区基站,作为目标基站;当能力需求信息中包括计算能力需求信息时,服务基站还可以将计算匹配度最高的目标邻区基站,作为目标基站。
其中,当UE的能力需求信息中的通信能力需求信息包括传输速率时,由于目标邻区基站的传输速率均大于或等于通信能力需求信息中的传输速率,因此,目标邻区基站的传输速率越高,表示目标邻区基站与UE之间的通信能力匹配度越高。
当UE的能力需求信息中的通信能力需求信息包括传输时延时,由于目标邻区基站的传输时延均小于或等于通信能力需求信息中的传输时延,因此,目标邻区基站的传输时延越小,表示目标邻区基站与UE之间的通信能力匹配度越高。
当UE的能力需求信息中的通信能力需求信息包括丢包率时,由于目标邻区基站的丢包率均小于或等于通信能力需求信息中的丢包率,因此,目标邻区基站的丢包率越小,表示目标邻区基站与UE之间的通信能力匹配度越高。
当UE的能力需求信息中的计算能力需求信息包括每秒运算次数(或每秒操作次数)时,由于目标邻区基站的每秒运算次数均大于通信能力需求信息中的每秒运算次数(或每秒操作次数),因此,目标邻区基站每秒运算次数(或每秒操作次数)越大,表示目标邻区基站与UE之间的计算能力匹配度越高。
可以理解的是,可以通过能力得分衡量目标邻区基站和UE之间的匹配的。例如,当UE的能力需求信息中包括至少两项能力需求时,可以计算目标邻区基站对应的能力得分,并根据能力得分确定目标基站,具体如下:
可以为每项能力设置至少两个数值区间,为每个数值区间设置相应的分数(该分数标识匹配度,匹配度越高,分数越高),为每项能力分配相应的权重值,所有权重值之和为1。每项能力对应的权重值可以根据每项能力的重要程度或优先级分配。某项能力越重要或优先级越高,其对应的权重值越大。
服务基站根据每个目标邻区基站的能力信息,确定每个目标邻区基站的每项能力所属的数值区间,从而确定其所属的数值区间对应的分数;根据每个目标邻区基站的每项能力对应的分数、以及每项能力对应的权重值,进行加权求和运算,得到每个目标邻区基站对应的能力得分,以便服务基站根据每个目标邻区基站各自对应的能力得分确定目标基站。服务基站可以从能力得分大于或等于预设能力分数阈值的目标邻区基站中,选择任意一个作为目标基站,也可以将分数最高的目标邻区基站作为目标基站。
可以理解的是,至少两项能力需求可以属于同一能力类型,也可以属于不同的能力类型。能力类型包括但不限于通信能力、计算能力以及存储能力。
当至少两项能力需求属于同一能力类型时,按照上述方法计算得到的最终分数为,该 类能力对应的能力得分。当至少两项能力需求属于不同的能力类型时,按照上述方法计算得到的能力得分为至少两类能力类型各自对应的分数。
如果能力需求信息中包括至少两类能力需求,每类能力类型包括至少两项能力时,可以按上述方法对每项能力进行加权求和运算,得到每类能力类型对应的分数;然后再按上述方法对每类能力的分数进行加权求和运算,计算得到至少两类能力对应的总分数。
可以理解的是,上述能力的重要程度或优先级可以根据UE的能力需求信息中的通信能力需求信息或计算能力需求信息确定,也可以由UE的业务策略确定,此处不做限定。某项能力对应的能力需求的要求越高,那么该项能力越重要或优先级越高。UE的业务策略可以从能力需求信息中获取,也可以由服务基站确定。
例如,服务基站可以根据UE的能力需求信息中的通信能力需求信息或计算能力需求信息,确定UE的业务策略。
当UE的能力需求信息中的通信能力需求信息包括传输速率时,如果传输速率大于预设传输速率阈值,那么UE的业务策略为通信优先策略。
当UE的能力需求信息中的通信能力需求信息包括传输时延或丢包率时,如果传输时延小于预设传输时延阈值,那么服务基站确认UE的业务策略为通信优先策略。
当UE的能力需求信息中的通信能力需求信息包括丢包率时,如果丢包率小于预设丢包率阈值,那么UE的业务策略为通信优先策略。
当UE的能力需求信息中的计算能力需求信息包括每秒运算次数(或每秒操作次数)时,如果每秒运算次数大于或等于预设每秒运算次数阈值,那么UE的业务策略为计算优先策略。
S114、服务基站发送切换命令至所述UE,所述切换命令包括所述目标基站的标识信息。
服务基站在确定目标基站之后,可以生成包含目标基站的标识信息的切换命令,并发送切换命令至UE。
可以理解的是,目标基站的标识信息可以包括移动网络码(Mobile Network Code,MNC)、位置区域码(location area code,LAC)、小区标识(cell ID)、基站的编码信息等。
S115、UE响应于所述切换命令,从所述服务基站切换至所述目标基站。
UE可以根据目标基站的标识信息,接入目标基站,从而实现从服务基站切换至目标基站。
上述方案,区别于现有技术中,根据邻区基站的信号质量指示UE切换基站的方案,本实施例中,服务基站可以根据UE的能力需求信息以及邻区基站的能力信息,指示UE切换至能够满足UE的能力需求的目标基站,以使UE切换到目标基站后,目标基站能够满足UE的业务需求,提高UE的通信质量。
请参见图3,基于图2,在另一实施例中,图3对应的实施例中S101的能力需求信息还可以包括业务策略,业务策略可以标识能力需求的优先级,所述业务策略包括通信优先策略或计算优先策略。业务策略用于确定目标基站。目标基站的通信能力或计算能力,与业务策略指示的能力需求之间的匹配度最高。其中,当所述业务策略为通信优先策略时,所述目标基站是所述邻区基站中满足所述能力需求信息,且通信能力最强的基站;当所述 业务策略为计算优先策略时,所述目标基站是所述邻区基站中满足所述能力需求信息,且计算能力最强的基站。
所述业务策略可以由所述UE通过以下任一项确定:所述UE的剩余电池电量、所述UE的处理器的使用率、所述UE对应的用户偏好信息、所述UE的处理器的温度。
业务策略包括但不限于通信优先策略,或计算优先策略。通信优先策略适用于对通信需求大,对计算需求和/或存储需求较小的业务。通信优先策略的业务包括但不限于云化计算类的应用程序(Application,App)所对应的业务,云化的App可以包括但不限于,云端渲染的游戏应用、直播应用等。例如,直播业务、定位业务、导航业务。
计算优先策略适用于对计算需求大,对通信需求较小的业务。计算优先策略的业务可以包括但不限于本地计算类的App所对应的业务,例如,本地计算业务、本地渲染业务(比如,拍照)。
在一种可能的实现方式中,业务策略可以由UE根据UE对应的用户偏好信息确定,用户偏好信息用于表示用户注重通信费用或通信质量。当所述用户偏好信息用于表示用户注重通信费用时,所述业务策略为计算优先策略;当所述用户偏好信息用于表示用户注重通信质量时,所述业务策略为通信优先策略。
用户偏好信息可以由UE分析用户的历史使用数据得到。例如,UE获取并分析用户在预设时长(例如半年或一年)内所签约的移动数据流量套餐、实际已使用的移动数据流量值,从而确定用户偏好信息。如果该移动数据流量套餐对应有的允许使用的流量阈值,并且用户实际已使用的移动数据流量值小于或等于允许使用的流量阈值,那么认为用户对通信费用比较敏感,用户比较注重通信费用。如果该移动数据流量套餐为不限流量套餐,那么认为用户比较注重通信质量。
在一种可能的实现方式中,业务策略可以由UE的处理器的使用率确定。当所述UE的处理器的使用率小于或等于预设使用率阈值时,所述业务策略为计算优先策略;当所述UE的处理器的使用率大于所述预设使用率阈值时,所述业务策略为通信优先策略。预设使用率阈值可以为50%。处理器包括中央处理器(Central Processing Unit,CPU),和/或,嵌入式神经网络处理器(Neural-network Processing Unit,NPU)。
示例性的,例如,如果所述UE的处理器的使用率小于或等于第一预设使用率阈值,那么所述业务策略为计算优先策略。第一预设使用率阈值可以根据UE的资源使用率较小,可用资源较多的情况进行设置,可以为40%。
如果所述UE的处理器的使用率大于第二预设使用率阈值,那么所述业务策略为通信优先策略。第二预设使用率阈值可以根据UE的处理器的使用率较多的情况进行设置。第二预设使用率阈值可以与第一预设使用率阈值相同,也可以不同。第二预设使用率阈值可以为40%、50%或80%等,此处不做限制。
当第二预设使用率阈值可以与第一预设使用率阈值不同时,如果UE的处理器的使用率大于第一预设使用率阈值,且小于或等于第二预设使用率阈值,那么UE可以从计算优先策以及通信优先策略中选择任一种策略,作为业务策略。
在一种可能的实现方式中,业务策略还可以由UE根据UE的剩余电池电量确定。
当所述剩余电池电量小于或等于预设电池电量阈值时,从所述通信优先策略和所述计算优先策略中选择耗电量最小的策略作为所述UE最终的业务策略。预设电池电量阈值可 以为10%,但并不限于此,可根据实际情况进行设置,此处不做限制。
在一种可能的实现方式中,业务策略还可以由所述UE的处理器的温度确定。当UE的处理器的温度大于或等于预设温度阈值时,所述业务策略为通信优先策略;当所述UE的处理器的温度小于所述预设温度阈值时,所述业务策略为计算优先策略。示例性的,预设温度阈值可以为30摄氏度,但并不限于此,预设温度阈值可根据实际情况进行设置,此处不做限制。
可以理解的是,UE在确定业务策略后,还可以根据UE能力以及业务策略确定通信能力需求信息、计算能力需求信息以及存储能力需求信息。UE能力可以包括UE的通信能力、计算能力,还可以包括存储能力。
例如,UE执行的业务为计算优先策略的业务时,UE可以根据自己的能力信息,将90%的计算资源分配给该业务,10%的通信资源以及80%的存储资源分配给该业务,那么该业务对应的通信能力需求为UE通信能力的10%,该业务对应的计算能力需求为UE计算能力的90%,该业务对应的存储需求为UE存储能力的80%。存储能力可以用存储空间的大小来衡量。
再例如,UE执行的业务为通信优先策略的业务时,UE可以根据自己的能力信息,将90%的通信资源分配给该业务,10%的计算资源以及80%的存储资源分配给该业务,那么该业务对应的计算能力需求为UE计算能力的90%,该业务对应的计算能力需求为UE计算能力的10%,该业务对应的存储需求为UE存储能力的80%。
相应地,S113中服务基站根据所述能力需求信息以及所述目标邻区基站的能力信息,从所述目标邻区基站中确定目标基站,可以具体为:根据所述能力需求信息以及所述目标邻区基站的能力信息,从所述目标邻区基站中确定与所述业务策略指示的能力需求匹配的目标基站。
服务基站可以根据业务策略确定优先级最高的能力需求信息,根据优先级最高的能力需求信息以及所述目标邻区基站的能力信息,从目标邻区基站中确定目标基站。目标基站的通信能力或计算能力,可以与业务策略指示的能力需求匹配度最高。
例如,当业务策略为通信优先策略时,服务基站根据目标邻区基站的能力信息中的通信能力信息,按通信能力从高到低的顺序,筛选出第一数目的目标邻区基站。服务基站可以将通信能力最好的一个目标邻区基站作为目标基站,也可以将第一数目的目标邻区基站中的任一个作为目标基站。第一数目可以为任意整数,第一数目小于目标邻区基站的数量。例如,目标邻区基站的数量为5,第一数目可以为1、2、3或4。
可以理解的是,当至少两个目标邻区基站的通信能力并列第一时,可以从中选择任意一个作为目标基站;还可以根据通信能力并列第一的至少两个目标邻区基站的计算能力信息,从中选择计算能力最高的一个目标邻区基站,作为目标基站。如果通信能力并列第一的至少两个目标邻区基站中,存在至少两个计算能力并列第一的目标邻区基站,那么从至少两个计算能力并列第一的目标邻区基站中,选择存储能力最高的目标邻区基站,作为目标基站。
当业务策略为计算优先策略时,服务基站根据目标邻区基站的能力信息中的计算能力信息,按计算能力从高到低的顺序,筛选出第二数目的目标邻区基站。服务基站可以将计算能力最好的一个目标邻区基站作为目标基站,也可以将第二数目的目标邻区基站中的任 一个作为目标基站。第二数目可以为任意整数,第二数目小于目标邻区基站的数量。第二数目与第一数目可以相同,也可以不同,此处不做限制。
可以理解的是,当至少两个目标邻区基站的计算能力并列第一时,可以从中选择任意一个作为目标基站;还可以根据计算能力并列第一的至少两个目标邻区基站的通信能力信息,从中选择通信能力最高的一个目标邻区基站,作为目标基站。如果计算能力并列第一的至少两个目标邻区基站中,存在至少两个通信能力并列第一的目标邻区基站,那么从至少两个通信能力并列第一的目标邻区基站中,选择存储能力最高的目标邻区基站,作为目标基站。
在本实施例中,服务基站可以根据UE的业务策略,从目标邻区基站中,优先选择与业务策略指示的能力需求匹配度高的目标基站。
请参见图4,基于图2,在另一种实施例中,S104中UE发送的测量报告中包括邻区基站各自对应的信号质量信息,在S113中,服务基站根据目标邻区基站的能力信息以及信号质量信息,从目标邻区基站中确定目标基站。信号质量信息用于服务基站从满足UE的能力需求的邻区基站中确定信号质量较好的目标基站。
具体的,服务基站可以从满足UE的能力需求的目标邻区基站中,选择信号质量最好的基站作为目标基站。
服务基站还可以根据信号质量信息,筛选出信号质量值大于或等于预设阈值的第一目标邻区基站,然后根据第一目标邻区基站的能力信息以及UE的能力需求信息,从第一目标邻区基站中选择匹配度最高的基站作为目标基站。
本实施例中,服务基站可以从目标基站中选择信号质量好的基站,作为目标基站,以提高UE的通信质量。
请参见图5,基于图4,在另一种实施例中,S101的能力需求信息还可以包括业务策略,业务策略用于确定目标基站。相应地,S113可以具体为:服务基站根据所述能力需求信息、所述目标邻区基站的能力信息以及信号质量信息,从目标邻区基站中确定与所述业务策略指示的能力需求匹配的目标基站。服务基站可以从满足UE的能力需求且信号质量较好的邻区基站中,选择与业务策略所标识的能力需求最匹配的目标基站;或者,从满足UE的能力需求,且与业务策略所标识的能力需求匹配较高的邻区基站中,选择信号质量最好的基站作为目标基站。
例如,图5对应的实施例中,服务基站根据信号质量信息,从满足UE的能力需求的邻区基站中筛选出信号质量值大于或等于预设阈值的第一目标邻区基站,之后,服务基站可以根据业务策略确定优先级最高的能力需求信息,根据优先级最高的能力需求信息以及第一目标邻区基站的能力信息,从第一目标邻区基站中确定目标基站。目标基站的通信能力或计算能力,与业务策略指示的能力需求匹配度最高。例如,当业务策略为通信优先时,通信能力需求信息的优先级最高,目标基站是满足能力需求信息且信号质量较好的邻区基站中,通信能力最强的基站。当业务策略为计算优先时,计算能力需求信息的优先级最高,目标基站是满足能力需求信息且信号质量较好的邻区基站中,计算能力最强的基站。
再例如,服务基站可以根据UE的能力需求信息中的业务策略确定优先级最高的能力需求信息,根据优先级最高的能力需求信息以及满足UE的能力需求的邻区基站的能力信息,从满足UE的能力需求的邻区基站中,确定与优先级最高的能力信息匹配度较高的目 标邻区基站,从该目标邻区基站中,选择信号质量最好的基站作为目标基站。与优先级最高的能力信息匹配度较高可以是指:目标邻区基站的目标能力信息与优先级最高的能力信息之间的匹配度大于或等于预设匹配的阈值;或者目标邻区基站的目标能力的值与优先级最高的能力信息对应的值之间的差值的绝对值较小。
例如,当业务策略为通信优先时,通信能力需求信息的优先级最高,目标基站是满足能力需求信息且通信能力较好的邻区基站中,信号质量最号的基站。当业务策略为计算优先时,计算能力需求信息的优先级最高,目标基站是满足能力需求信息且计算能力较好邻区基站中,信号质量最好的基站。
具体的实现方法请参见图3对应的实施例中S113中根据所述能力需求信息以及所述目标邻区基站的能力信息,从所述目标邻区基站中确定与所述业务策略匹配的目标基站的相关描述。
本实施例中,服务基站可以从信号质量满足要求的目标基站中,选择与UE的能力需求匹配度高的基站作为目标基站;或者从满足预设要求的目标邻区基站中,选择信号质量好的基站作为目标基站,从而在提高UE的通信质量的同时能够更好地满足UE的业务需求。
请参见图6,基于图2,在另一种实施例中,S110中的切换请求响应信息包括邻区基站对应的MEC服务器的第一标识。相应地,S113可以具体为:服务基站根据目标邻区基站的能力信息以及MEC服务器的标识,从目标邻区基站中确定目标基站。邻区基站对应的MEC服务器的第一标识用于服务基站判断邻区基站所属的MEC服务器与所述服务基站所属的MEC服务器是否相同,根据判断结果确定目标基站。目标基站所属的MEC服务器与服务基站所属的MEC服务器可以相同,也可以不同。其中,服务基站从满足UE能力需求信息的邻区基站中,优先选择与服务基站属于同一个MEC服务器的邻区基站作为目标基站。
具体的,服务基站根据服务基站对应的第一MEC服务器的标识以及目标邻区基站对应的第二MEC服务器的标识,判断第一MEC服务器的标识与第二MEC服务器的标识是否相同,从而判断目标邻区基站所属的MEC服务器是否与服务基站所属的MEC服务器相同。
如果所有目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器均不同,那么服务基站根据目标邻区基站的能力信息以及UE的能力需求信息,计算目标邻区基站的能力信息与UE的能力需求信息之间的匹配度,并根据匹配度确定目标基站。可以选择匹配度最高的目标邻区基站作为目标基站。计算目标邻区基站的能力信息与UE的能力需求信息之间的匹配度的方法参见图2对应的实施例中S113中的相关描述,此处不赘述。
如果与服务基站属于同一个MEC服务器的目标邻区基站的数量为一个,那么服务基站将该目标邻区基站作为目标基站。
如果与服务基站属于同一个MEC服务器的目标邻区基站的数量为至少两个,那么服务基站将该至少两个目标邻区基站的能力信息与UE的能力需求信息进行比较,根据比较结果,确定与能力需求信息匹配度最高的目标基站,并将其作为目标基站。确定与能力需求信息匹配度最高的目标基站的方法请参照图2对应的实施例中的相关描述,此处不赘述。
由于目标基站所属的MEC服务器与服务基站所属的MEC服务器可以相同,也可以不同,当目标基站所属的MEC服务器与所述服务基站所属的MEC服务器不同时,在S114之后,且在S115中所述UE从所述服务基站切换至所述目标基站之前,还包括:
若所述UE的业务所对应的应用为MEC系统中不需要跟踪UE状态信息的状态独立的应用,则指示所述目标基站所属的目标MEC服务器实例化一个相同的应用;
若所述UE的业务所对应的应用为与用户活动相关的应用,则指示所述服务基站所属的源MEC服务器向所述目标MEC服务器迁移用户相关信息。
具体地,UE根据目标基站的标识信息与目标基站建立通信连接之前,根据UE中已发起的业务所属的目标应用的应用标识,判断目标应用是否为MEC系统中不需要跟踪UE状态信息的状态独立的应用。如果目标应用为MEC系统中不需要跟踪UE状态信息的状态独立的应用,那么指示目标基站所属的目标MEC服务器上实例化一个相同的应用。如果目标应用不是MEC系统中不需要跟踪UE状态信息的状态独立的应用,结束基站切换流程。
UE还可以根据UE中已发起的业务所属的目标应用的应用标识,判断目标应用是否为与用户活动相关的应用。如果目标应用为与用户活动相关的应用,那么指示服务基站所属的源MEC服务器向目标MEC服务器迁移用户相关信息。如果目标应用不是与用户活动相关的应用,结束基站切换流程。
例如,当UE在切换基站前已发起通话业务,目标基站所属的MEC服务器与服务基站所属的MEC服务器不同时,UE切换至目标基站前,指示目标基站所属的目标MEC服务器实例化一个“电话应用”,以使得UE能够保持UE与电话应用之间的业务连接。
再例如,当UE在切换基站前已发起直播业务(例如视频直播、游戏直播等),目标基站所属的MEC服务器与服务基站所属的MEC服务器不同时,UE切换至目标基站前,指示服务基站所属的源MEC服务器向目标MEC服务器迁移用户相关信息,以使得UE能够保持UE与直播应用之间的业务连接。
当目标基站所属的MEC服务器与服务基站所属的MEC服务器相同时,UE切换至目标基站之前,UE不需要对切换至目标基站的业务所属的应用进行初始化,能够更快速地将UE中已发起的业务切换至目标基站,以使得UE能够较快地获得相关的服务。
本实施例中,服务基站可以优先选择与服务基站属于同一MEC服务器的目标基站,这样在切换基站时,不需要迁移用户信息,也不需要在目标基站上重新实例化(或初始化)UE的应用,通过减少UE迁移用户信息或重新实例化UE的应用的时间,可以减少用户从目标基站中获取服务的等待时长,减少UE掉话或业务间断的情况发生。

具体的,服务基站如果确认所有目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器均不同,那么可以根据目标邻区基站的能力信息、UE的能力需求信息中的业务策略、通信能力需求信息、计算能力需求信息,确定目标基站。
例如,服务基站根据业务策略确定需要优先满足的能力需求,之后,根据目标邻区基站的能力信息,从目标邻区基站中确定与业务策略匹配的目标基站。
具体的实现方法请参见图3对应的实施例中S113中根据所述能力需求信息、所述目标邻区基站的能力信息,从所述目标邻区基站中确定与所述业务策略指示的能力需求匹配的目标基站的相关描述。

需要说明的是,当目标基站所属的MEC服务器与所述服务基站所属的MEC服务器不同时,UE在接收到切换命令之后,并且在S115中所述UE从所述服务基站切换至所述目标基站之前,UE还可以指示目标基站所属的目标MEC服务器上实例化一个相同的应用,或者指示所述服务基站所属的源MEC服务器向所述目标MEC服务器迁移用户相关信息。具体实现方式参见图6对应的实施例中的相关描述,此处不赘述。

具体的,服务基站根据服务基站对应的第一MEC服务器的标识以及目标邻区基站对应的第二MEC服务器的标识,判断第一MEC服务器的标识与第二MEC服务器的标识是否相同,从而判断目标邻区基站所属的MEC服务器是否与服务基站所属的MEC服务器相同。

在一种可能的实现方式中,UE根据切换命令确定目标基站的方法可以为:根据所述UE的能力需求信息、切换命令中包含的目标邻区基站的能力信息,从目标邻区基站中确定目标基站。
其中,UE根据UE的能力需求信息、目标邻区基站的能力信息确定目标基站的方法,可以参见图2对应的实施例中S113中基站确定目标基站的方法的相关描述,此处不赘述。

UE根据第三MEC指示标识从满足UE能力需求信息的邻区基站中,优先选择与服务基站属于同一个MEC服务器的邻区基站作为目标基站。当存在至少两个满足能力需求的目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器相同时,目标基站为至少两个目标邻区基站中,与UE的能力需求信息匹配度最高的基站。即,目标基站可以是至少两个目标邻区基站中,通信能力最强或计算能力最强的基站。

在另一种可能的实现方式中,测量报告中可以包括邻区基站的信号质量信息。S115可以具体为:根据第三MEC指示标识以及目标邻区基站的信号质量信息,从目标邻区基站中确定目标基站。
UE可以从满足UE的能力需求的目标邻区基站中,优先选择与服务基站属于同一个MEC服务器的基站作为目标基站,当存在至少两个满足能力需求的目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器相同时,从中选择信号质量好的基站作为目标基站。即,目标基站为至少两个目标邻区基站中,通信质量最好的基站。
如果所有目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器均不同,那么UE根据目标邻区基站的信号质量信息,从中选择信号质量最好的目标邻区基站作为目标基站。

UE从满足UE能力需求信息的目标邻区基站中,优先选择与服务基站属于同一个MEC服务器的基站作为目标基站,当存在至少两个满足能力需求的目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器相同时,目标基站是至少两个目标邻区基站中,信号质量好或与业务策略所标识的能力需求匹配度最高的基站。当所有目标邻区基站所属 的MEC服务器均与服务基站所属的MEC服务器不同时,服务基站可以从满足UE的能力需求且信号质量较好的邻区基站中,选择与业务策略所标识的能力需求最匹配的目标基站;或者,从满足UE的能力需求,且与业务策略所标识的能力需求匹配较高的邻区基站中,选择信号质量最好的基站作为目标基站。
具体的,UE根据第三MEC指示标识判断是否存在与服务基站属于同一个MEC服务器的目标邻区基站,如果存在,还可以确定与服务基站属于同一个MEC服务器的目标邻区基站的数量。之后,UE可以根据判断结果、与服务基站属于同一个MEC服务器的目标邻区基站的数量、能力需求信息、目标邻区基站的能力信息以及信号质量信息,确定目标基站。UE确定目标基站的具体实现方法与图9对应的实施例中S113中的相关描述,此处不赘述。
需要说明的是,当目标基站所属的MEC服务器与服务基站所属的MEC服务器不同时,在S115中所述UE从所述服务基站切换至所述目标基站之后,UE还可以指示目标基站所属的目标MEC服务器上实例化一个相同的应用,或者指示所述服务基站所属的源MEC服务器向所述目标MEC服务器迁移用户相关信息。具体实现方式参见图6对应的实施例中的相关描述,此处不赘述。
本实施例中,UE优先筛选出与服务基站属于同一MEC服务器的目标邻区基站,然后,再从中筛选出信号质量较好的目标邻区基站,最后从中筛选出与业务策略指示的能力需求匹配度最高的目标基站。或者,在筛选出与服务基站属于同一MEC服务器的目标邻区基站之后,可以从中筛选出与业务策略指示的能力需求匹配度较高的目标邻区基站,最后从中筛选出信号质量最好的目标基站。
如图13所示,在一种实施例中,在图11的基础上,S111中服务基站获取到切换请求响应信息之后,执行S114,切换命令中包括切换请求响应信息中的能力指示标识以及邻区基站的能力信息。UE在获取到服务基站发送的切换命令之后,执行S115~S116。具体如下:
S115、响应于所述切换命令,根据所述切换命令确定满足所述能力需求信息的目标邻区基站。
根据切换命令确定满足能力需求信息的目标邻区基站可以具体包括:根据切换命令中的能力指示标识确定满足UE的能力需求信息的目标邻区基站。
UE根据能力指示标识确定满足UE的能力需求信息的目标邻区基站,与服务基站根据能力指示标识确定满足UE的能力需求信息的目标邻区基站的方法相同,具体实现过程参见图2中S112中的相关描述,此处不赘述。
S116、根据所述切换命令,从所述目标邻区基站中确定目标基站,从服务基站切换至目标基站。

区别于现有技术中由服务基站确定待切换的目标基站的方案,本实施例中,UE可以根据服务基站发送的相关信息确定目标基站,这样UE可以更灵活地切换基站。另外,UE可以从满足UE的能力需求的目标邻区基站中,可以优先与服务基站属于同一个MEC服务器的基站作为目标基站;当所有目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器均不同,或者存在至少两个与服务基站属于同一个MEC服务器的目标邻区基站时,可以从中选择信号质量较好的基站作为目标基站。这样可以使得目标基站在满足UE的业务需求的前提下,可以减少用户从目标基站中获取服务的等待时长,减少UE掉话或业务间断的情况发生,提高UE的通信质量。
如图14所示,在一种实施例中,在图13的基础上,S110中邻区基站发送的切换请求响应信息还包括邻区基站的MEC服务器的标识;S114中,服务基站发送的切换命令还可以包括邻区基站所属的MEC服务器的标识。
由于UE可以在接入服务基站后,可以获取到服务基站所属的MEC服务器的标识,因此,切换命令中可以不包括服务基站所属的MEC服务器的标识。
在一种可能的实现方式中,S116可以具体为:根据服务基站的MEC服务器的标识、目标邻区基站的MEC服务器的标识、目标邻区基站的能力信息,从目标邻区基站中确定目标基站。UE可以根据服务基站的MEC服务器的标识以及目标邻区基站的MEC服务器的标识,是否存在与服务基站属于同一个MEC服务器的目标邻区基站,优先选择与服务基站属于同一个MEC服务器的邻区基站作为目标基站。当存在至少两个满足能力需求的目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器相同时,目标基站为至少两个目标邻区基站中,与UE的能力需求信息匹配度最高的基站。即,目标基站可以是至少两个目标邻区基站中,通信能力最强或计算能力最强的基站。
如果所有目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器均不同,目标基站可以为与UE的能力需求信息匹配度最高的基站。
在另一种可能的实现方式中,能力需求信息还包括业务策略,S116可以具体为:UE根据所述能力需求信息、服务基站的MEC服务器的标识、目标邻区基站的MEC服务器的标识以及目标邻区基站的能力信息,从目标邻区基站中确定与所述业务策略所指示的能力需求匹配的目标基站。

在另一种可能的实现方式中,能力需求信息中还可以包括业务策略,测量报告中可以包括邻区基站的信号质量信息。S116可以具体为:根据所述能力需求信息、服务基站的MEC服务器的标识、目标邻区基站的MEC服务器的标识、目标邻区基站的能力信息以及信号质量信息,从目标邻区基站中确定目标基站。
UE从满足UE能力需求信息的目标邻区基站中,优先选择与服务基站属于同一个MEC服务器的基站作为目标基站,当存在至少两个满足能力需求的目标邻区基站所属的MEC服务器与服务基站所属的MEC服务器相同时,目标基站是至少两个目标邻区基站中,信号质量好或与业务策略所标识的能力需求匹配度最高的基站。当所有目标邻区基站所属的MEC服务器均与服务基站所属的MEC服务器不同时,服务基站可以从满足UE的能力需求且信号质量较好的邻区基站中,选择与业务策略所标识的能力需求最匹配的目标基站;或者,从满足UE的能力需求,且与业务策略所标识的能力需求匹配较高的邻区基站中,选择信号质量最好的基站作为目标基站。
以上UE确定目标基站的具体实现过程参见图12对应的实施例中S115的相关描述,此处不赘述。
需要说明的是,在图12以及图14对应的实施例中,当目标基站所属的MEC服务器与服务基站所属的MEC服务器不同时,在S116中所述UE从所述服务基站切换至所述目标基站之前,UE还可以指示目标基站所属的目标MEC服务器上实例化一个相同的应用,或者指示所述服务基站所属的源MEC服务器向所述目标MEC服务器迁移用户相关信息。具体实现方式参见图6对应的实施例中的相关描述,此处不赘述。
区别于现有技术中由服务基站确定待切换的目标基站的方案,本实施例中,UE根据服务基站发送的相关信息确定目标基站所获得的有益效果,与图13对应的实施例的有益效果基本相同,此处不赘述。
