Description

聚合连接建立方法、装置及存储介质 技术领域
本公开涉及无线通信技术领域，特别涉及一种聚合连接建立方法、装置及存储介质。
背景技术
在无线通信中，聚合技术是为提高数据传输速率引入的，使得终端可以在多个载频上同时传输数据的技术。
在相关技术中，每个小区根据自己的部署情况为终端设置聚合配置。终端在小区之间切换时，切换后的目标小区和切换前的源小区的聚合配置可能不同，因此终端需要先释放源小区的聚合配置，在成功接入到目标小区后，目标小区再将新的聚合配置发送给终端。然而，上述方式需要终端等待目标小区发送聚合配置，从而导致数据传输速率下降。

本公开提供一种终端切换小区后建立聚合连接的方案，为了便于理解，下面首先介绍本公开涉及的一些概念。
(1)聚合技术以及聚合连接
为了提高数据传输速率，第4代移动通信技术(the 4th Generation mobile communication technology，4G)系统，又称长期演进(Long Term Evolution，LTE)系统中引入了聚合技术，包括载波聚合CA技术、双重连接DC技术、长期演进及无线局域网载波聚合LWA技术等，使得终端可以在多个载频上同时传输数据。每个小区根据自己的部署情况为终端设置CA/DC/LWA配置，包括CA所用的载频、DC所用的小区和LWA所用的WLAN接入点(Access Point，AP)等。
其中，基于聚合技术建立的无线连接可以称为聚合连接，包括基于载波聚合CA技术的CA连接，基于双重连接DC技术的DC连接，或者，基于长期演进及无线局域网载波聚合LWA技术的LWA连接等。
(2)CHO切换命令
为了提高切换的鲁棒性，第5代移动通信(5G)技术，又称新空口(New Radio，NR)技术，提出了基于条件的切换过程CHO，该过程中发送的切换命令称为CHO切换命令，即网络可以提前为终端发送CHO切换命令，其中携带切换目标小区和切换触发条件，当切换触发条件得到满足时，UE自行发起切换过程，不需要网络再发送切换命令。
(3)源小区、目标小区、候选小区、源基站和目标基站
在本公开中，对于一个终端来说，该终端在进行小区切换之前接入的小区 可以称为该终端的源小区，该源小区对应基站可以称为源基站。
终端在切换时，可以从一个或者多个小区中选择一个小区进行切换，其中，该一个或者多个小区可以称为候选小区，而终端选择要切换到的小区可以称为该终端的目标小区，该目标小区对应基站可以称为目标基站。

综上所述，本公开实施例所示的方案，终端在进行小区切换之前，候选小区对应的基站根据源基站发送的终端信息，向源基站发送包含候选小区的聚合配置信息的切换命令，由源基站生成包含至少一个候选小区各自的聚合配置信息的CHO切换命令并发送给终端，使得终端可以在切换至目标小区时，直接从该目标小区的聚合配置信息中获取目标聚合配置，并基于目标聚合配置建立聚合连接，在此过程中，终端不需要等待切换至目标小区之后，再由目标小区设置聚合配置，在切换过程中即可以完成聚合连接的建立，以便在成功接入目标小区后马上就可以使用聚合技术进行数据传输，从而提高通过CHO切换命令进行小区切换的过程中的数据传输速率。
请参考图5，其示出了本公开实施例提供的一种聚合连接建立方法的方法流程图，如图5所示，该聚合连接建立方法可以应用于图1所示的实施环境中，该聚合连接建立方法可以包括以下步骤。
在步骤501中，终端向源基站上报终端信息，源基站接收该终端的终端信息；该终端信息包括该终端的终端环境UE context以及该终端的测量结果。
其中，终端环境UE context中包含该终端的无线接入层的配置，比如无线承载配置等。
上述终端的测量结果可以是终端对周围各个小区和/或WLAN AP的测量结果，比如，测量目标(即各小区的标识或者各WLAN AP的标识)，以及信号强度等。
其中，终端接入源基站中的源小区时，还测量该源小区之外的其它各个小区或WLAN AP的信号质量，并将获得的测量结果以及自身的UE context上报给源基站。
在步骤502中，源基站向至少一个候选小区各自对应的基站发送该终端的终端信息，候选小区对应的基站接收该终端信息。
源基站接收到终端上报的终端信息后，可以向终端可能切换至的至少一个候选小区各自的基站发送该终端信息。
其中，上述至少一个候选小区可以终端信息中包含有对应测量结果的各个小区。
或者，上述至少一个候选小区也可以是基站根据终端信息中的测量结果选择的一个或者多个小区。
或者，上述至少一个候选小区也可以是终端根据测量结果指定的一个或者多个小区。
在步骤503中，候选小区的基站向该源基站返回该候选小区的切换命令，源基站接收该切换命令。
其中，该切换命令中包含该候选小区的聚合配置信息。
在本公开实施例中，候选小区的基站接收到源基站发送的终端信息后，根据该终端信息中的UE context判断是否接纳该终端切换至本小区，并在判断出可以接纳该终端切换至本小区时，根据终端信息中终端对该候选小区之外的其它小区或者WLAN AP的测量结果，生成该候选小区的聚合配置信息，并将该候选小区的聚合配置信息添加至切换命令中返回给源基站。
可选的，该候选小区的聚合配置信息中包含至少一条聚合配置，该聚合配置中包含定时器。
可选的，该聚合配置中还包含承载配置、测量配置以及信号质量门限；该承载配置用于指示对应的聚合配置的无线承载，该测量配置用于指示对应的聚合配置的参考信号类型和信号质量类型。
其中，一个候选小区为终端生成的聚合配置信息中，可以包含一条或多条聚合配置，并且，对于不同的聚合技术，相应的聚合配置也不相同。
比如，当候选小区支持双重连接DC技术时，该候选小区返回的切换命令中可以携带DC配置列表(对应上述聚合配置信息)，该DC配置列表中包含一条或者多条DC配置(对应上述聚合配置)，每个DC配置包括承载配置、测量配置、信号质量门限和定时器。其中承载配置包括，频率，辅小区标识等；测量配置包括参考信号类型，比如同步信号块(Synchronization Signal Block，SSB)，信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)等； 信号质量类型，又称为测量量，比如参考信号接收功率(Reference Signal Receiving Power，RSRP)，参考信号接收质量(Reference Signal Receiving Quality，RSRQ)，信道状态信息信号与干扰加噪声比(CSI-Signal to Interference plus Noise Ratio，CSI-SINR)等。
再比如，当候选小区支持载波聚合CA技术时，该候选小区返回的切换命令中可以携带CA配置列表(对应上述聚合配置信息)，其中包含一条或多条CA配置(对应上述聚合配置)，每个CA配置包括承载配置、测量配置、信号质量门限和定时器。其中承载配置包括，频率，辅小区标识等，测量配置包括参考信号类型，比如SSB，CSI-RS等；测量量，比如RSRP，RSRQ，CSI-SINR等。
再比如，当候选小区支持LWA技术时，该候选小区返回的切换命令中可以携带LWA配置列表(对应上述聚合配置信息)，其中包含一条或多条LWA配置(对应上述聚合配置)，每个LWA配置包括承载配置、测量配置、信号质量门限和定时器。其中承载配置包括，WLAN AP标识等；测量配置包括参考信号类型，比如SSB，CSI-RS等；测量量，比如RSRP，RSRQ，CSI-SINR等。
在步骤504中，源基站根据该至少一个候选小区各自返回的切换命令，生成CHO切换命令。
在该步骤中，源基站根据各个候选小区各自对应的基站返回的，各个候选小区的切换命令，生成包含各个候选小区的聚合配置信息的CHO切换命令。
在步骤505中，源基站向终端发送CHO切换命令，终端接收该CHO命令。
在本公开实施例中，源基站生成上述CHO切换命令之后，即可以将该CHO切换命令发送给终端，以便终端在检测出CHO切换命令对应的切换条件满足时，执行发起小区切换。
在步骤506中，终端启动该至少一个候选小区各自的聚合配置信息中的各条聚合配置的定时器。
终端接收到上述CHO切换命令后，即可以启动CHO切换命令中各条聚合配置的定时器。
可选的，对于第一聚合配置，若该第一聚合配置的定时器超时，则终端删除该第一聚合配置；该第一聚合配置是该至少一个候选小区各自的聚合配置信息中的任一聚合配置。
也就是说，UE收到CHO切换命令后即可以启动每个聚合配置对应的定时器，当某个定时器超时，则删除对应的聚合配置。
在步骤507中，当终端切换至至少一个候选小区中的目标小区时，从各条有效聚合配置中获取目标聚合配置。
其中，上述有效聚合配置是该目标小区的聚合配置信息中，定时器未超期的聚合配置。
其中，终端根据CHO切换命令中的切换条件，以及，终端自身对各个候选小区的测量结果，选择至少一个候选小区中的目标小区进行切换时，可以从目标小区对应的各条定时器未超时的聚合配置中，选择一个配置建立聚合连接，以便在切换完成后即可以使用聚合技术进行数据传输。
在一种可能的实现方式中，在从目标小区对应的各条有效聚合配置中获取目标聚合配置时，终端可以根据该各条有效聚合配置的承载配置和该各条有效聚合配置的测量配置，测量获得该各条有效聚合配置的信号质量；并将该各条有效聚合配置中，信号质量高于对应的信号质量门限的聚合配置获取为该目标聚合配置。
也就是说，在本公开实施例中，当UE选择某一个目标小区触发CHO切换后，可以根据对应的配置测量辅小区/WLAN AP的信道质量，选择还未删除的(即定时器未超时)，且符合信号质量门限要求的辅小区/WLAN AP配置建立聚合连接。
可选的，当该各条有效聚合配置中，信号质量高于对应的信号质量门限的聚合配置包括至少两条聚合配置时，终端可以将该至少两条聚合配置中，在该目标小区的聚合配置信息中排列最前的一条聚合配置获取为该目标聚合配置。
也就是说，当目标小区对应有多个辅小区/WLAN AP满足要求时，终端可以按照列表顺序，选择靠前的聚合配置作为目标聚合配置。
或者，终端也可以将该至少两条聚合配置中的随机一条聚合配置获取为该目标聚合配置。
也就是说，当目标小区对应有多个辅小区/WLAN AP满足要求时，终端也可以随机选择其中一个配置为目标聚合配置。
在步骤508中，终端建立该目标聚合配置对应的聚合连接。
在本公开实施例中，终端可以根据目标聚合配置中的承载配置，建立对应的聚合连接。
比如，当目标聚合配置是CA配置时，该聚合连接为基于载波聚合CA技术的连接；当目标聚合配置是DC配置时，该聚合连接为基于双重连接DC技术的 连接；当目标聚合配置是LWA配置时，该聚合连接是基于长期演进与无线局域网载波聚合LWA技术的连接。
在一个可能的实现方式中，终端在建立该目标聚合配置对应的聚合连接之后，还删除该至少一个候选小区各自的聚合配置信息中，除了该目标聚合配置之外的其它定时器未超时的聚合配置。
在一个可能的实现方式中，终端在建立该目标聚合配置对应的聚合连接之后，还向目标基站发送该聚合连接的承载信息，该目标基站是该目标小区对应的基站；其中，当该聚合连接是基于CA或者DC的连接时，该承载信息包括辅小区标识；当该聚合连接是基于LWA的连接时，该承载信息包括无线局域网接入点标识。
也就是说，当UE切换完成后，该UE向目标基站发送重配完成消息，其中，重配完成消息中携带上述步骤建立聚合连接时所选择的辅小区/WLAN AP标识，并删除其他未使用的聚合配置。
在一个可能的实现方式中，上述聚合连接建立的流程可以如下：
1)UE向源基站上报测量结果后，源基站向各个候选小区所在基站(比如基站a和基站b)发送切换请求，该切换请求中携带UE context和UE对各个小区的测量结果。
2)基站a向源基站发送切换命令，其中携带DC配置列表如下：
DC配置1：辅小区标识为000，频率为100，参考信号为SSB，测量量为RSRP，门限为-98db，定时器为1s。
DC配置2：辅小区标识为001，频率为101，参考信号为SSB，测量量为RSRP，门限为-98db，定时器为1.5s。
3)基站b向源基站发送切换命令，其中携带CA配置列表如下：
CA配置1：辅小区标识为010，频率为110，参考信号为SSB，测量量为RSRP，门限为-98db，定时器为1s。
CA配置2：辅小区标识为011，频率为111，参考信号为SSB，测量量为RSRP，门限为-98db，定时器为1.5s。
4)源基站基于收到的切换命令，生成CHO切换命令，并发送给UE。
5)UE收到切换命令后，启动上述4个聚合配置各自的定时器。
6)UE决定向小区a(即上述基站a对应的小区)发起切换，则在频率100上测量小区000的SSB，并在频率101上测量小区001的SSB，获得测量结果 分别为-97db和-100db，其中，辅小区000满足信号质量门限，则根据DC配置1建立辅小区000的承载，用于后续数据传输。
7)UE在切换完成之后，向小区a发送重配完成消息，其中携带辅小区标识000。
综上所述，本公开实施例所示的方案，终端在进行小区切换之前，源基站向终端发送CHO切换命令；并且，该CHO切换命令中包含至少一个候选小区各自的聚合配置信息，使得终端可以在切换至目标小区时，直接从目标小区的聚合配置信息中获取目标聚合配置，并基于目标聚合配置建立聚合连接，在此过程中，终端不需要等待切换至目标小区之后，再由目标小区设置聚合配置，在切换过程中即可以完成聚合连接的建立，以便在成功接入目标小区后马上就可以使用聚合技术进行数据传输，从而提高通过CHO切换命令进行小区切换的过程中的数据传输速率。
