背景技术
随着长期演进(Long Term Evolution；简称：LTE)技术的发展，出现了no cell系统。No cell系统包括：控制器(controller)和发送点(Transmit Point；简称：TP)。多个TP的覆盖构成一个超级小区(hyper cell)。控制器对hyper cell的无线资源进行管理；TP为用户设备提供空口资源。当用户设备接入hyper cell时，通过TP和controller与核心网进行通信。
当用户设备在移动过程中，移动到LTE小区和hyper cell同时覆盖的区域时，为了提高用户设备的吞吐量，需要用户设备同时连接LTE小区和hyper cell。但是，现有技术还未提供使用户设备同时连接LTE小区和hyper cell的解决方案。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例例如能够以除了在这里图示或描述 的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
图1A为本发明实施例提供的双连接方法实施例的一种应用场景架构图。如图1A所示，本应用场景中，基站和控制器是共站(Collocated)的。基站和控制器共站则基站和控制器的消息是共享的，即基站获取到的消息控制器也相应地可以收到。No cell系统包括控制器和控制器管理的TP，多个TP的信号覆盖构成一个Hyper cell。图1中示出了一个控制器和3个TP构成一个no cell系统。图1A中的闭合线段11构成的区域为基站覆盖的区域；闭合线段12构成的区域为Hyper cell覆盖的区域，闭合线段13构成的区域为一个TP覆盖的区域。可以认为闭合线段11构成的区域和闭合线段12构成的区域近似重合。在该重合区域内，用户设备可以同时通过基站和控制器与核心网交互信息，提高用户设备的吞吐量。
图1B为本发明实施例提供的双连接方法实施例的另一种应用场景架构图。如图1B所示，其与图1A的区别在于，基站和控制器不是共站的，且基站和控制器之间有接口，基站和TP之间没有接口。图1C为本发明实施例提供的双连接方法实施例的再一种应用场景架构图。如图1C所示，其与图1B的区别在于，基站和控制器之间有接口，基站和各个TP之间也有接口。图1B和图1C中均示出了一个控制器和3个TP构成一个no cell系统。
在no cell系统中，控制器对hyper cell的无线资源进行管理。用户设备可以通过接入控制器管理的TP来接入控制器。以数据下行传输为例，由控制器将数据发送给控制器为用户设备选择的TP，再由该TP发送给用户设备。
本发明实施例所涉及的基站可以是通用移动通信系统(Universal Mobile Telecommunications System；简称：UMTS)中的基站，也可以是LTE中的演进型基站，还可以是新的无线接入技术(New Radio Access Technology；简称：NR)基站。本发明实施例所涉及的用户设备可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端 可以经无线接入网(例如，Radio Access Network，简称为：RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，简称为：PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，简称为：WLL)站、个人数字助理(Personal Digital Assistant，简称为：PDA，)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
图2为本发明实施例提供的双连接方法实施例一的信令交互图。本发明实施例提供的双连接方法可以应用于图1A、图1B和图1C所示的应用场景中。如图2所示，本发明实施例提供的双连接方法，包括：
S201：待接入的控制器为用户设备配置参数。
S202：待接入的控制器将该参数发送给基站。
具体地，控制器为用户设备配置参数并发送给基站以供基站向用户设备发送包括该参数的第一连接重配置消息。该控制器为用户设备待接入的控制器。用户设备与基站已建立连接。
待接入的控制器可以自行进行决策为用户设备配置参数。该参数可以包括待接入的控制器向用户设备配置的专有连接标识(Dedicated Connection Identifier；简称：DCID)、接入序列、发送所述接入序列的信道、上行参考信号、发送所述上行参考信号的信道、发送所述上行参考信号的周期等参数。用户设备在接收到参数后，可以根据参数与待接入的控制器建立连接。
S203：基站从待接入的控制器接收待接入的控制器为用户设备配置的参数。
S204：基站向用户设备发送第一连接重配置消息。
第一连接重配置消息用于指示用户设备根据该参数与待接入的控制器建立连接。第一连接重配置消息中包括待接入的控制器为用户设备配置的参数。
具体地，待接入的控制器配置了参数后，如果基站和待接入的控制器共站，则基站可以直接获取待接入的控制器向用户设备配置的参数；如果基站和待接入的控制器不共站，则基站和待接入的控制器之间可以通过通信接口的信令交互获取该参数。基站获得参数后，将其封装在第一连接重配置消息中发送给用户设备。
需要说明的是，这里的连接重配置消息可以是无线资源控制(Radio Resource Control；简称：RRC)连接重配置消息，也可以是其他配置消息。本实施例对此不做限制。第一连接重配置消息中还可以包括基站对用户设备配置的参数。这是因为在待接入的控制器为用户设备配置了参数之后，基站可能也需要改变对用户设备的配置，即用户设备重新进行配置。
S205：用户设备从基站接收第一连接重配置消息。
S206：用户设备根据第一连接重配置消息中的参数与待接入的控制器建立连接。
具体地，用户设备可以在接收到第一连接重配置消息后，根据第一连接重配置消息中的参数进行配置。用户设备可以根据第一连接重配置消息中的参数，以DCID作为其接入待接入的控制器时的ID，在发送接入序列的信道上发送序列，进行随机接入。接入后即可进行数据传输。当然，用户设备还可以采用其他方式根据第一连接重配置消息中的参数与待接入的控制器建立连接，本发明实施例对此不做限制。
可选的，在用户设备配置完成后，还可以向基站发送第一连接重配置完成消息。
用户设备接入待接入的控制器所管理的小区后，控制器可以为用户设备选取一个待接入的控制器管理的待连接的TP，则用户设备可以通过基站与核心网通信，还可以通过待连接的TP、控制器以及基站与核心网进行通信。以数据下行传输为例，例如，基站可以直接将对时延要求高的数据发送给用户设备，基站可以将对时延要求低的数据发送给控制器，控制器发送给TP，TP再发送给用户设备。这样，用户设备可以同时从基站和控制器获得数据，提高了UE的吞吐量。
本发明实施例提供的双连接方法，通过待接入的控制器为用户设备配置参数，并将该参数发送给基站，基站接收到该参数后，向用户设备发送包括 该参数的第一连接重配置消息，用户设备接收基站发送的第一连接重配置消息，并根据该参数与待接入的控制器建立连接，在用户设备接入控制器所管理的小区时，用户设备可以预先根据第一连接重配置消息中的参数进行配置，实现了用户设备同时接入基站的覆盖区域和控制器的覆盖区域，以便于用户设备通过基站与核心网交互，以及用户设备通过基站、控制器与核心网交互，从而，提高了用户设备的吞吐量。
图3为本发明实施例提供的双连接方法实施例二的信令交互图。本发明实施例提供的双连接方法应用在图1A所示的应用场景中。在图2所示实施例的基础上，本发明实施例对S206之后的步骤进行详细说明。本发明实施例中控制器和基站共站。如图3所示，本发明实施例提供的双连接方法包括：
S301：待接入的控制器为用户设备配置参数。
可选的，该参数包括：接入序列、发送所述接入序列的信道、上行参考信号、发送所述上行参考信号的信道、发送所述上行参考信号的周期以及DCID。
S302：待接入的控制器将该参数发送给基站。
可选的，待接入的控制器可以通过其与基站之间的通信接口将该参数发送给基站。
S303：基站从待接入的控制器接收待接入的控制器为用户设备配置的参数。
S304：基站向用户设备发送第一连接重配置消息。
S305：用户设备从基站接收第一连接重配置消息。
S306：用户设备根据第一连接重配置消息中的参数与待接入的控制器建立连接。
S301-S306的实现方式和技术原理与S201-S206相同，此处不再赘述。
可选的，在用户设备配置完成后，还可以向基站发送第一连接重配置完成消息。
S307：用户设备通过发送上行参考信号的信道向待接入的控制器管理的TP发送上行参考信号。
该上行参考信息用于TP生成第一测量报告。
具体地，用户设备可以向Hyper cell中的所有TP发送上行参考信号。图 3示出了当用户设备向所有TP发送上行参考信号时，有两个TP，即TP1和TP2，接收到了上行参考信号。
S308：TP接收到上行参考信号后生成第一测量报告。
具体地，TP在接收到上行参考信号后可以根据自身的算法生成第一测量报告。
S309：TP向基站发送第一测量报告。
S310：基站从TP接收第一测量报告，并根据第一测量报告确定TP中的待连接的TP。
其中，第一测量报告是TP接收到用户设备通过发送上行参考信号的信道发送的上行参考信号后所生成的。
具体地，第一测量报告中包含有TP接收到的上行参考信号功率或质量信息。在一种实现方式中，基站在接收到TP发送的第一测量报告后，选择第一测量报告中功率最大的测量报告所对应的TP为待连接的TP。在本实施例中，以基站确定的待连接的TP为TP1进行说明。

图7为本发明实施例提供的双连接方法实施例六的信令交互图。图7所示实施例提供的双连接方法在上述实施例的基础上，对控制器为新的无线接入技术(New Radio Access Technology；简称：NR)基站时进行双连接的步骤进行详细说明：
S701：LTE基站向NR基站发送增加请求消息。
其中，增加请求消息用于指示NR基站为用户设备配置参数和用于指示在LTE基站与NR基站之间为用户设备的承载建立隧道。
除此之外，增加请求消息中还携带有用户设备能力的协商参数。该协商参数可以是告知NR基站该用户设备在NR基站的能够支持的峰值数据速率(peak data rate)、能够使用的端口、能够使用的最大功率、能够使用的载波、最大传输块大小等。具体地，LTE基站会决策用户设备在LTE基站侧会需要多大的数据速率R1，然后依据用户设备总的峰值数据速率R，告知NR基站上用户设备能够支持的峰值数据速率，即为R减去R1。
综上，该增加请求消息中会携带以下参数中的至少一项：能够支持峰值数据速率、能够使用的端口、能够使用的最大功率、能够使用的载波、能够支持的最大传输块大小。这些值可以由LTE基站确定。
本发明实施例所涉及的LTE基站也可以是通用移动通信系统(Universal Mobile Telecommunications System；简称：UMTS)中的基站。No cell系统是NR的一种可能的实现。
S702：NR基站从LTE基站接收增加请求消息。
S703：NR基站根据增加请求消息为用户设备配置参数。
S704：NR基站向LTE基站发送增加请求确认消息。
其中，该增加请求确认消息中包括完整的NR RRC消息。该完整的NR RRC消息中包括NR基站为用户设备配置的参数。
S705：LTE基站从NR基站接收增加请求确认消息。
S706：LTE基站向用户设备发送LTE RRC消息。
其中，该LTE RRC消息中包括LTE基站为用户设备配置的参数以及NR RRC消息。
具体地，LTE基站在接收到NR基站发送的增加请求确认消息后，不解析NR基站发送的NR RRC消息，而是将该NR RRC消息作为一个容器 (container)携带于LTE RRC消息中发送给用户设备。在该LTE RRC消息中除了携带NR RRC消息之外，还包括LTE基站为用户设备配置的LTE基站侧的参数。
S707：用户设备从LTE基站接收LTE RRC消息。
S708：用户设备执行LTE基站和NR基站的配置。
具体地，用户设备内部会存在两个RRC实体，LTE RRC实体和NR RRC实体，分别用于解析LTE RRC消息和NR RRC消息，并执行相应的配置。
在本发明实施例中，用户设备接收到LTE RRC消息后，由LTE RRC实体对该LTE RRC消息进行解析，并在LTE RRC实体中执行相应的RRC配置。同时，该LTE RRC实体不会解析LTE RRC消息中携带的NR RRC消息，而是将该NR RRC消息发送给NR RRC实体。由NR RRC实体对NR RRC消息进行解析并执行相应的配置。
两个RRC实体执行相应的RRC配置，可能会成功，也会是失败，相应的需要产生各自的配置完成消息或配置失败消息。
在第一种可能的实现方式中，LTE RRC实体执行LTE RRC配置，如果完成则产生LTE RRC配置完成消息，如果失败则产生LTE RRC配置失败消息；NR RRC实体执行NR RRC配置，如果完成则产生NR RRC配置失败消息，如果失败则产生NR RRC配置失败消息。NR RRC实体将产生的NR RRC配置完成消息或NR RRC配置失败消息发送给LTE RRC实体，LTE RRC实体不进行解析，携带于LTE RRC配置完成消息或者LTE RRC配置失败消息中。
在第二种可能的实现方式中，针对LTE RRC实体和NR RRC实体两侧配置都完成的情况以及LTE RRC实体配置完成了，NR RRC实体配置失败的情况，处理方式与第一种方式一样，即LTE RRC实体产生LTE RRC配置完成消息，NR RRC实体产生NR RRC配置完成消息或者NR RRC配置失败消息，并携带于LTE RRC配置完成消息中。而针对LTE RRC实体配置失败的情况，NR RRC实体停止配置。在此之前，LTE RRC实体会向NR RRC实体发送一个失败指示。该失败指示用于指示LTE RRC侧配置失败，NR RRC实体接收到该失败指示后，停止NR侧配置。LTE RRC实体产生LTE RRC配置失败消息，NR RRC实体产生NR RRC配置失败消息并传给LTE RRC实体， 作为一个container携带于LTE RRC配置失败消息中。
在第三种可能的实现方式中，其与第一种可能的实现方式的区别在于，NR RRC实体还可以将配置结果告知LTE RRC实体，此时LTE RRC配置完成或者LTE RRC配置失败消息中还可以携带NR RRC实体的配置状态指示消息。即，在该种实现方式中，LTE RRC配置结果消息中除了包括LTE RRC配置结果、NR RRC配置结果消息，还包括NR RRC实体的配置状态指示消息。
在第四种可能的实现方式中，其与第二种可能的实现方式的区别在于，针对LTE RRC实体配置失败的情况，NR RRC实体停止配置，此时LTE RRC配置完成或者LTE RRC配置失败消息中还可以携带NR RRC实体的配置失败指示消息。即，在该种实现方式中，LTE RRC配置结果消息中除了包括LTE RRC配置结果、NR RRC配置结果消息，还包括NR RRC实体的配置失败指示消息。
需要说明的是，在上述过程中，当用户设备中的LTE RRC实体配置完成，NR RRC实体配置失败时，LTE RRC实体的配置依然是执行的。
S709：用户设备向LTE基站发送LTE RRC配置结果消息。
其中，该LTE RRC配置结果消息可以是LTE RRC配置失败消息，或者，LTE RRC配置完成消息。该LTE RRC配置结果消息中还包括NR RRC配置结果消息。该NR RRC配置结果消息可以是NR RRC配置完成消息，或者，NR RRC配置失败消息。
S710：LTE基站从用户设备接收LTE RRC配置结果消息。
S711：LTE基站解析LTE RRC配置结果消息，确定LTE RRC实体的配置结果，并获取NR RRC配置结果消息。
具体地，LTE基站解析LTE RRC配置结果消息，确定用户设备中的LTE RRC是否配置成功。LTE基站不解析LTE RRC配置结果消息中的NR RRC配置结果消息。
需要说明的是，针对S708中的第三种可能的实现方式和第四种可能的实现方式，LTE基站解析LTE RRC配置结果消息，除了可以确定出LTE RRC实体的配置结果，并获取到NR RRC配置结果消息之外，还可以根据LTE RRC配置结果消息中的NR RRC实体的配置状态指示消息，确定NR RRC的配置 结果。
S712：LTE基站将NR RRC配置结果消息发送给NR基站。
S713：NR基站从LTE基站接收NR RRC配置结果消息。
S714：NR基站解析NR RRC配置结果消息，确定NR RRC实体的配置状态指示消息。
S715：NR基站将NR RRC实体的配置状态指示消息发送给LTE基站。
S716：LTE基站从NR基站接收NR RRC实体的配置状态指示消息。
S717：LTE基站根据NR RRC实体的配置状态指示消息确定NR RRC实体的配置结果。
需要说明的是，针对S708中的第三种可能的实现方式和第四种可能的实现方式，S715-S717不需要执行。
具体地，在一种场景中，在S711中，LTE基站确定出LTE RRC实体的配置结果为配置完成，且在S717中，LTE基站确定NR RRC实体的配置结果为配置完成，用户设备即可完成双连接，进行数据传输。以数据下行传输为例，例如，LTE基站可以将部分数据直接发送给用户设备，将其他数据发送给NR基站，由NR基站发送给用户设备。这样，用户设备可以同时从LTE基站和NR基站获得数据，提高了UE的吞吐量。
在另一种场景中，在S711中，LTE基站确定出LTE RRC实体的配置结果为配置失败，且在S717中，LTE基站确定NR RRC实体的配置结果为配置成功，则针对S708中的第一种可能的实现方式，需执行以下步骤；另外，在S711中，LTE基站确定出LTE RRC实体的配置结果为配置失败，且LTE基站确定NR RRC实体的配置结果为配置成功，则针对S708中的第三种可能的实现方式，同样需要执行以下步骤：
S718：LTE基站向用户设备发送释放消息。
其中，该释放消息用于指示用户设备释放NR侧的配置。
S719：用户设备从LTE基站接收释放消息。
S720：用户设备根据释放消息释放NR配置。
S718-S720的执行可以让用户设备节省资源，提高用户设备资源的利用率。
需要说明的是，本发明实施例中是以LTE基站为主基站、NR基站为辅 基站进行说明的，可以理解的是，当NR基站为主基站、LTE基站为辅基站时，需将上述过程中的LTE基站和NR基站的执行过程互换，即将上述过程中由LTE基站执行的步骤变为由NR基站执行，NR基站执行的步骤变为由LTE基站执行。同时，在用户设备内部，LTE RRC实体和NR RRC实体的执行过程互换，即将用户设备内部由LTE RRC实体执行的步骤变为由NR RRC实体执行，NR RRC实体执行的步骤变为由LTE RRC实体执行。
本发明实施例提供的双连接方法，通过LTE基站向NR基站发送增加请求消息，NR基站接收LTE基站发送的增加请求消息，NR基站根据增加请求消息为用户设备配置参数，NR基站向LTE基站发送增加请求确认消息，LTE基站接收NR基站发送的增加请求确认消息，LTE基站向用户设备发送LTE RRC消息，用户设备接收LTE基站发送的LTE RRC消息，用户设备执行LTE基站和NR基站的配置，用户设备向LTE基站发送LTE RRC配置结果消息，LTE基站接收用户设备发送的LTE RRC配置结果消息，LTE基站解析LTE RRC配置结果消息，确定LTE RRC实体的配置结果，并获取NR RRC配置结果消息，LTE基站将NR RRC配置结果消息发送给NR基站，NR基站接收LTE基站发送的NR RRC配置结果消息，NR基站解析NR RRC配置结果消息，确定NR RRC实体的配置状态指示消息，NR基站将NR RRC实体的配置状态指示消息发送给LTE基站，LTE基站接收NR基站发送的NR RRC实体的配置状态指示消息，LTE基站根据NR RRC实体的配置状态指示消息确定NR RRC实体的配置结果，因此，在用户设备实现双连接后，有数据下行时，LTE基站可以直接将一部分数据发送给用户设备，将另外一部分数据发送给NR基站，再由NR基站发送给用户设备，提高了用户设备的吞吐量。
