背景技术
双连接(Dual Connectivity)技术也被称为基站间载波聚合技术或者多流聚合技术,双连接技术是指用户设备同时从至少两个基站接收数据,即主基站(master base station或primary base station)和辅基站(secondary base station)同时为用户设备提供通信服务。典型的场景是用户设备同时从宏站和小站接收数据,宏站作为主基站提供广覆盖以减少切换次数,小站作为辅基站分担数据提升热点地区容量。

基站,可以是GSM或CDMA中的基站(Base Transceiver Station,简称BTS),也可以是WCDMA中的基站(Node B),还可以是LTE中的演进型基站(eNB或e-Node B,evolved Node B),本发明并不限定。基站也包括各种接入网节点的控制节点,例如UMTS中的无线网口控制器(Radio Network Controller,简称RNC),或管理多个小基站的控制器等。
本发明实施例以长期演进(Long Term Evolution,LTE)通信***为例,但不限于此。如图1所示,在LTE通信***的架构示意图中,无线通信网络100可以包括至少一个基站110和核心网设备130,用以支撑用户设备(User Equipment,UE)120进行通信。例如,基站110可以是LTE中的演进型基站(evolved NodeB,eNB),该基站110可以支持或管理一个或多个小区。采用双连接(Dual Connectivity)模式的用户设备120需要和网络通信时,可以同时从至少两个基站110接收数据,即至少两个基站110为用户设备120提供服务。其中,基站110可以实现主基站和/或辅基站的功能。核心网设备130可以包括移动性管理实体(Mobile Management Entity,MME)。

301:目标主基站接收源主基站发送的切换请求,切换请求包括源辅基站的第一配置信息,源主基站与源辅基站共同向用户设备提供服务。
302:目标主基站向源辅基站发送第一指示,第一指示用于指示源辅基站保持不变。
303:目标主基站向源主基站发送切换确认,切换确认包括源辅基站的第二配置信息,用于目标主基站和源辅基站共同向用户设备提供服务。
本实施例中,第一配置信息可以为辅小区组的配置信息。例如,该第一配置信息可包含以下至少一种:源辅基站的辅小区组的小区标识,源辅基站的辅小区组的小区测量信息,源辅基站的辅小区组的承载配置信息,源辅基站的主辅小区配置。上述小区测量信息可以为测量结果参考信号接收功率(Reference signal received power,RSRP)上述承载配置信息可以为承载的类型(如SCG承载或分流(Split)承载),或承载的服务质量(Quality of Service, QoS)参数。上述SCG承载可以为该承载所有的数据都建立在源辅基站,由源辅基站直接和服务网关(Serving Gateway,SGW)间传输数据。上述split承载为该承载的数据可以同时建立在源主基站和源辅基站,数据经由源主基站和服务网关间传输。例如,目标主基站可以根据SCG中服务小区的测量信息增删SCG中的服务小区,也可增加该源辅基站的其他小区即不被SCG所涵盖的小区作为服务小区。目标主基站可根据上述第一配置信息或/和该目标主基站的本地配置信息判决是否继续保留原有的SCG。例如,该目标主基站的本地配置信息可以为以下至少一种:该目标主基站是否支持双连接特性,是否支持保持源辅基站不变的功能,该目标主基站本身负载情况等。
本实施例中,上述第一指示可以具体用于指示源辅基站继续作为服务用户设备的辅基站,且服务用户设备的主基站由源主基站变更为目标主基站。
例如,当目标主基站确定在切换前后保持源辅基站作为用户设备的辅基站不变,可以向源辅基站发送辅基站增加请求或辅基站修改请求。该辅基站增加请求或辅基站修改请求分别对应辅基站新增或修改的场景,随后详述。
以下以辅基站增加请求(SeNB Addition Request)为例,该辅基站增加请求包含第一指示,用于指示源主基站发生改变但源辅基站保持不变。该第一指示也可以指示在切换流程中或基于切换流程,该源辅基站保持不变。该第一指示可以为新的信元(IE,information element),也可以为其他任意的隐式的或显示的指示。当源辅基站接收到该第一指示后,即使检测到重复的用户设备上下文信息,重复的承载或重复的用户设备签约信息,也不判断源辅基站增加失败。例如,该源辅基站在切换前已经从源主基站获取了该用户设备的上下文信息,如服务网关(Serving Gateway,SGW)为SGW与源主基站之间的承载分配的传输路径信息(例如因特网协议(Internet Protocol,IP)地址和隧道协议(通用分组无线业务隧道协议(General Packet Radio Service,GPRS)Tunneling Protocol,GTP)标识),但在该SeNB Addition Request消息中又重复接收的相同的SGW为承载分配的传输路径信息。如果SeNB Addition Request消息未包含该第一指示,源辅基站将回复辅基站增加失败(SeNB  Addition Failure)消息给目标主基站。如果SeNB Addition Request消息包含该第一指示,源辅基站则认为重复是允许的,将回复辅基站增加确认(SeNB Addition Acknowledge)消息给目标主基站。
本发明实施例中,目标主基站可以接收源主基站发送的第三指示,用于指示目标主基站保留源辅基站继续作为用户设备的辅基站。
因而,本实施例可以实现在主基站切换过程中,辅基站保持不变,实现切换前后始终实现双连接通讯。进一步,可以避免在切换完成,目标主基站才增加用于用户设备的辅基站,减少因切换造成的时延。
在本实施例中,目标主基站可以根据第一配置信息获取第二配置信息。例如,目标主基站可以接收源辅基站根据第一配置信息获取的第二配置信息,并将该第二配置信息包含在切换确认消息中发给源主基站。上述第二配置信息可以包括以下至少一种:源辅基站的辅小区组的小区标识,源辅基站的辅小区组的小区测量信息,源辅基站的辅小区组的承载配置信息,源辅基站的主辅小区配置。
本发明实施例中,针对源辅基站在主基站切换过程中保持不变,在源主基站到目标主基站切换过程时,目标主基站决定给用户设备增加相同的辅基站即源辅基站。可以有两种实现方式:
第一种实现方式,可以通过辅基站增加流程实现,目标主基站发送辅基站增加请求给源辅基站,指示源辅基站继续作为用户设备的辅基站保持不变。
针对第一种实现方式,当源主基站收到目标主基站发送的切换确认消息,源主基站可以触发源辅基站释放用户设备上下文,保留承载。
第二种实现方式,可以通过辅基站修改流程实现,源主基站发送辅基站修改请求给源辅基站,指示源辅基站继续作为用户设备的辅基站保持不变。
针对第二种实现方式,可选的,目标主基站向源辅基站发送源辅基站分配的用户设备标识,用于源辅基站识别用户设备,源辅基站分配的用户设备标识由源主基站发送至目标主基站。
针对第二种实现方式,可选的,目标主基站接收源辅基站或源主基站发 送的传输路径信息,用于目标主基站完成源辅基站和服务网关之间的传输路径切换。
针对第二种实现方式,可选的,目标主基站向源主基站发送第二指示,用于指示源主基站保留源辅基站继续作为用户设备的辅基站。
上述切换确认消息可以包含上述第二指示,该第二指示用于指示源主基站保留源辅基站继续作为用户设备的辅基站。源主基站根据第二指示,保留源辅基站继续作为用户设备的辅基站。
例如,当源主基站接收到该第二指示,将不请求源辅基站释放UE上下文,或者将不向源辅基站发送数据转发信息,或指示源辅基站所有承载或部分承载不需要转发数据。该第二指示也可以为隐式指示,如源主基站可以解析第二配置信息,判断该源辅基站是被释放还是继续保留。
本实施例中,源辅基站可以将第二配置信息发送给用户设备。如果用户设备继续原有的辅基站上的承载不变,则可根据第二配置信息,不复位承载的媒体接入控制(Medium Access Control,MAC)实体,不重建立承载的无线链路控制(Radio Link Control,RLC)实体,根据新的安全参数重配承载的分组数据汇聚层(Packet Data Convergence Protocol,PDCP)(例如根据新的基站密钥KeNB衍生新的辅基站密钥SKeNB,从而衍生出在源辅基站上数据传递的加密密钥)。可以理解,当承载不变时,用户设备与源辅基站之间的数据无线承载(Data Radio Bearer,DRB)保持不变,可以用原先的配置即MAC和/或RLC。
以下以第一种实现方式为例,即通过辅基站增加流程,详细描述基于切换的双连接通信。如图4所示,该实现方式主要通过源主基站、目标基站和辅基站的交互完成,包括:

可选的,目标主基站也可以根据策略拒绝第三指示。例如,目标主基站负载较轻,不需要辅基站分担数据,则可以拒绝增加源辅基站继续作为服务用户设备的辅基站。例如,目标基站可以在切换确认中指示源主基站拒绝增加源辅基站继续作为服务用户设备。
403、目标主基站向源辅基站发送辅基站增加请求,辅基站增加请求包括第一指示。
上述第一指示可参考上文中的描述,此处不再赘述。

可选的,切换确认包括第二配置信息,用于目标主基站和源辅基站共同向用户设备提供服务。
407、源主基站向源辅基站发送释放请求。
该释放请求用于请求源辅基站释放用户设备的承载或用户设备的上下文,或者将向源辅基站发送数据转发信息,或指示源辅基站所有承载或部分承载需要转发数据。
以下以第二种实现方式为例,即通过辅基站修改流程,详细描述基于切 换的双连接通信。如图5所示,该实现方式主要通过源主基站、目标基站和辅基站的交互完成,包括:
501、源主基站向目标主基站发送切换请求,该切换请求中包括源辅基站的第一配置信息。
上述第一配置信息可参考上文中的描述,此处不再赘述。
可选的,该切换请求中包括源辅基站分配的用户设备标识,例如可以为X2用户设备应用层标识(UE AP ID),或小区无线网络临时标识网络标识(C-RNTI)。本实施例中,该源辅基站分配的用户设备标识可以用于在切换之前用于标识体现源辅基站与源主基站为用户设备提供服务,或用于在切换后用于标识体现源辅基站与目标主基站为用户设备提供服务。
可选的,该切换请求中包括源主基站发送的传输路径信息,用于目标主基站完成源辅基站和服务网关之间的传输路径切换。
502、目标主基站确定在切换前后保持源辅基站作为用户设备的辅基站不变。

可选的,目标主基站也可以根据策略拒绝第三指示。例如,目标主基站负载较轻,不需要辅基站分担数据,则可以拒绝增加源辅基站继续作为服务用户设备的辅基站。例如,目标基站可以在切换确认中指示源主基站拒绝增加源辅基站继续作为服务用户设备。
503、目标主基站向源辅基站发送辅基站修改请求,该辅基站修改请求包括第一指示。
可选的,该辅基站修改请求包括源辅基站分配的用户设备标识。进一步, 该辅基站修改请求还可以包括用户设备标识。该用户设备标识可以为目标主基站新分配的标识。
第一指示用于指示源辅基站保持不变。具体的,第一指示可以用于指示源辅基站继续作为服务用户设备的辅基站,且服务用户设备的主基站由源主基站变更为目标主基站。该第一指示也可以指示在切换流程中或基于切换流程,指示该源辅基站保持不变。该第一指示可以为新的IE,也可以为其他任意的隐式的或显示的指示。当源辅基站接收到该第一指示后,即使检测到重复的用户设备上下文信息,重复的承载或重复的用户设备签约信息,也不判断源辅基站修改失败。
例如,第一指示为隐式的指示时,第一指示包括源辅基站分配的用户设备标识(以源辅基站用户设备应用层标识S-SeNB UE AP ID为例)和用户设备标识(以T-MeNB UE AP ID为例),使得源辅基站接收到辅基站修改请求后,根据目标主基站携带的用户设备标识和自身保存的用户设备标识(以源主基站用户设备应用层标识S-MeNB UE AP ID为例)得知服务用户设备的主基站由源主基站变更为目标主基站、如果辅基站修改请求(SeNB Modification Request)消息未包含该第一指示,源辅基站将回复辅基站修改失败(SeNB Modification Failure)消息给目标主基站。如果SeNB Addition Request消息包含该第一指示,源辅基站则认为重复是允许的,将回复辅基站修改确认(SeNB Modification Acknowledge)消息给目标主基站。上述第一指示可以在源辅基站接收到与保存在自身相同的源辅基站分配的用户设备标识和不同的主基站分配的用户设备标识时,避免辅基站修改流程失败。

507、源主基站保留源辅基站继续作为服务用户设备的用户设备。
可选的,源主基站在接收到切换确认后,根据第二指示不向源辅基站发送辅基站释放请求。例如,源主基站不触发源辅基站释放用户设备的承载或用户设备的上下文,或者源主基站保留源辅基站继续作为服务用户设备的用户设备。
可选的,当源主基站接收到该第二指示,将不请求源辅基站释放UE上下文,或者将不向源辅基站发送数据转发信息,或指示源辅基站所有承载或部分承载不需要转发数据。该第二指示也可以为隐式指示,如源主基站可以解析第二配置信息,判断该源辅基站是被释放还是继续保留。又如,如果UE继续原有的辅基站上的承载不变,该UE可根据第二配置信息,将不复位承载的MAC实体,不重建立承载的RLC实体,根据新的安全参数重配承载的PDCP实体(例如根据新的KeNB衍生新的SKeNB,从而衍生出在源辅基站上数据传递的加密密钥)。
508、目标主基站向MME发送路径切换请求。
路径切换请求包括传输路径信息,该传输路径信息可以根据源辅基站或源主基站发送的传输路径信息获取,用于完成源辅基站和服务网关之间的传输路径切换。例如,目标主基站向MME发送的传输路径信息可以包括自源辅基站或源主基站获取的传输路径信息,和传输路径信息。
可选的,上述路径切换请求只携带传输路径信息发生变化的承载信息给 服务网关。例如,目标主基站向MME发送指示消息,该指示消息用于指示MME需要更新传输路径信息发生变化的承载信息。
本实施例,实现了在用户设备的主基站从源主基站切换至目标主基站的过程中源辅基站保持不变。由于在切换过程中源辅基站没有被释放,避免了现有机制中由于切换过程源辅基站被释放、并在切换完成后重新增加该源辅基站,而产生的时延问题。同时避免了现有机制中由于切换过程中源辅基站被释放,而导致的用户设备和源辅基站之间的数据通信中断的问题。

例如,当处理机802确定在切换前后保持源辅基站作为用户设备的辅基站不变,可以触发收发机801向源辅基站发送辅基站增加请求或辅基站修改请求。该辅基站增加请求或辅基站修改请求分别对应实施例一中辅基站新增或修改的场景,具体的辅基站新增或修改的场景可参考实施例一中的描述,此处不再赘述。
本发明实施例中,收发机801可以接收源主基站发送的第三指示,用于指示目标主基站保留源辅基站继续作为用户设备的辅基站。
因而,本实施例可以实现在主基站切换过程中,辅基站保持不变,实现切换前后始终实现双连接通讯。进一步,可以避免在切换完成,目标主基站才增加用于用户设备的辅基站,减少因切换造成的时延。
在本实施例中,收发机801可以根据第一配置信息获取第二配置信息。例如,收发机801可以接收源辅基站发送的根据第一配置信息获取的第二配 置信息,并将该第二配置信息包含在切换确认消息中发给源主基站。上述第二配置信息可以包括以下至少一种:源辅基站的辅小区组的小区标识,源辅基站的辅小区组的小区测量信息,源辅基站的辅小区组的承载配置信息,源辅基站的主辅小区配置。
本发明实施例中,针对源辅基站在主基站切换过程中保持不变,在源主基站到目标主基站切换过程时,目标主基站决定给用户设备增加相同的辅基站即源辅基站。可以有两种实现方式:
第一种实现方式,可以通过辅基站增加流程实现,目标主基站利用收发机801发送辅基站增加请求给源辅基站,指示源辅基站继续作为用户设备的辅基站保持不变。
针对第一种实现方式,当源主基站收到收发机801发送的切换确认消息,源主基站可以触发源辅基站释放用户设备上下文,保留承载。
第二种实现方式,可以通过辅基站修改流程实现,目标主基站利用收发机801发送辅基站修改请求给源辅基站,指示源辅基站继续作为用户设备的辅基站保持不变。

上述切换确认消息可以包含上述第二指示,该第二指示用于指示源主基站保留源辅基站继续作为用户设备的辅基站。源主基站根据第二指示,保留源辅基站继续作为用户设备的辅基站。
例如,当源主基站接收到该第二指示,将不请求源辅基站释放UE上下文, 或者将不向源辅基站发送数据转发信息,或指示源辅基站所有承载或部分承载不需要转发数据。该第二指示也可以为隐式指示,如源主基站可以解析第二配置信息,判断该源辅基站是被释放还是继续保留。
本实施例中,源辅基站可以将第二配置信息发送给用户设备。如果用户设备继续原有的辅基站上的承载不变,则可根据第二配置信息,不复位承载的MAC实体,不重建立承载的RLC实体,根据新的安全参数重配承载的PDCP实体(例如根据新的KeNB衍生新的SKeNB,从而衍生出在源辅基站上数据传递的加密密钥)。可以理解,当承载不变时,用户设备与源辅基站之间的DRB保持不变,可以用原先的配置即MAC和/或RLC。
通过图8所示装置,实现了在用户设备的主基站从源主基站切换至目标主基站的过程中源辅基站保持不变。由于在切换过程中源辅基站没有被释放,避免了现有机制中由于切换过程源辅基站被释放、并在切换完成后重新增加该源辅基站,而产生的时延问题。同时避免了现有机制中由于切换过程中源辅基站被释放,而导致的用户设备和源辅基站之间的数据通信中断的问题。

切换请求用于目标主基站向源主基站发送切换确认,切换确认包括目标辅基站的配置信息,用于目标主基站和目标辅基站共同向用户设备提供服务。
本发明实施例中,上述源辅基站的配置信息和目标辅基站的配置信息可参考上文中的描述,此处不再赘述。
本发明实施例中,图19所示的装置还包括:
发送单元1902,用于向目标主基站发送第一传输路径信息,第一传输路径信息为目标辅基站分配的用于目标辅基站和服务网关之间的数据传输;
接收单元1901,还用于:接收目标主基站发送的第二传输路径信息,第二传输路径信息为服务网关分配的用于目标辅基站和服务网关之间的数据传输。
本发明实施例中,上述第一指示用于目标主基站向源辅基站发送第二指示,第二指示用于指示目标主基站增加目标辅基站作为用户设备的辅基站。
通过图19所示装置,实现了在用户设备的主基站从源主基站切换至目标主基站的过程中,将用户设备的辅基站从源辅基站切换至目标辅基站。由于在切换过程中增加目标辅基站作为用户设备的辅基站,实现切换前后始终实现双连接通讯,避免了现有机制中由于切换过程源辅基站被释放、并在切换完成后重新增加目标辅基站,而产生的时延问题。同时避免了现有机制中由于切换过程中源辅基站被释放,而导致的用户设备和辅基站之间的数据通信中断的问题。
