Description

双连接拆建方法和装置 技术领域
本发明涉及通信领域，具体而言，涉及一种双连接拆建方法和装置。
背景技术
长期演进(Long Term Evolution，简称为LTE)网络包括演进的通用陆地无线接入网(Evolved Universal Terrestrial Radio Access Network，简称为E-UTRAN)及对应的核心网(Core Network，简称为CN)。E-UTRAN包括演进基站(evolved Node B，简称为eNB)。CN包括移动管理实体(Mobile Management Entity，简称为MME)和服务网关(Serving Gateway，简称为S-GW)等。eNB和CN之间通过S1接口连接，eNB之间可通过X2接口连接。一个eNB可以管理一个或多个小区(Cell)。
由于频谱资源的匮乏，以及移动用户的大流量业务的激增，采用高频点如3.5GHz进行热点覆盖的需求日益明显。高频点的信号衰减比较厉害，小区的覆盖范围比较小，采用低功率小小区(Small Cell)的基站成为新的应用场景。为了增强Small Cell部署网络的移动性能及增加用户吞吐量，引入了一种新的增强方案称作双连接(Dual Connectivity，简称为DC)。如图1所示，双连接下终端可以同时与两个基站保持连接，其中一个基站称为主基站(Master eNB，简称为MeNB)，另一个基站称为次基站(Secondary eNB，简称为SeNB)。终端首先连接到MeNB(一般为宏小区(Macro Cell)基站)，然后根据情况(例如，业务需求、无线环境、设备能力等)增加或释放SeNB(一般为Small Cell基站)。
本发明的发明人在研究过程中发现，Small Cell覆盖范围比较小，信号衰弱又比较快，在双连接时增加Small Cell作为SeNB如果也采用与切换一样的策略，则可能由于切换门限设的太高而降低了对SeNB的利用率；然而，如果增加SeNB的门限设的太低，又容易出现增加SeNB后又马上释放等移动性问题。
针对相关技术中采用切换门限建立或者拆除双连接导致次基站利用率低或者次基站频繁释放的问题，目前尚未提出有效的解决方案。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本发明实施例提供了一种双连接拆建方法，图2是根据本发明实施例的双连接拆建方法的流程示意图，如图2所示，包括如下的步骤：
步骤S202，确定终端所接入的主基站或该主基站的邻区基站当前配置的次基站增加/释放门限；
步骤S204，根据该次基站增加/释放门限，建立/拆除邻区基站与终端的连接。
通过上述步骤，采用根据主基站或邻区基站配置的次基站增加/释放门限进行终端和邻区基站的连接的建立/拆除，使得主基站或邻区基站的次基站增加/释放门限可以独 立于主基站或邻区基站的切换门限而单独地配置，进而可以根据邻区基站与多个终端之间的双连接的建立/拆除的情况，动态调整主基站或邻区基站的次基站增加/释放门限，解决了采用切换门限建立或者拆除双连接导致次基站利用率低或者次基站频繁释放的问题。通过上述步骤，可以将基站切换门限与次基站增加/释放门限独立进行协商，使得在不影响基站的切换性能的情况下，可以灵活实现次基站的增加/释放，从而提升了次基站的利用率，也避免了次基站的频繁释放。
优选地，主基站或邻区基站当前配置的次基站增加/释放门限可以是通过人工进行单独配置的(如人工对各个基站分别进行的初始配置或人工对全部基站进行的全局配置)，也可以是由主基站根据相关的统计结果与邻区基站进行协商配置的。例如，在步骤S202之前，主基站发送协商消息至邻区基站，其中，该协商消息设置为指示主基站的一个或者多个小区当前配置的次基站增加/释放门限，或者该协商消息设置为指示邻区基站的一个或者多个小区的次基站增加/释放门限。其中，在邻区基站接收到该协商消息之后，邻区基站可以根据协商消息所指示的邻区基站的次基站增加/释放门限或者次基站增加/释放门限偏移量，调整邻区基站的次基站增加/释放门限。
优选地，上述的协商消息中携带的信息包括以下至少之一：(1)主基站针对邻区基站的小区的次基站增加/释放门限当前值；(2)主基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量；(3)邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量。
其中，信息(3)设置为调整邻区基站的次基站增加/释放门限。
优选地，主基站的次基站增加/释放门限偏移量是相对于主基站当前配置的次基站增加/释放门限的偏移量。
邻区基站的次基站增加/释放门限偏移量是相对于邻区基站当前配置的次基站增加/释放门限的偏移量。
优选地，为了避免主基站和邻区基站之间的信息丢失导致协商的次基站增加/释放门限不一致的问题，信息(2)较优地与信息(1)同时传输。
优选地，在常规的设计中，对于次基站的一个小区往往配置一个全局的次基站增加/释放门限就能够提升次基站的利用率，避免次基站的频繁释放，即对应于所有终端状态配置一个相同的主基站针对邻区基站的小区的次基站增加/释放门限。然而为了实现更精确化的次基站增加/释放，还可以采用在协商消息中携带分别对应于多个或者多组终端状态的多个次基站增加/释放门限，其中，终端状态包括以下至少之一：终端的 业务类型、终端的数据流量大小、终端的移动状态。通过该方式，对于终端的不同终端状态配置不同的次基站增加/释放门限，从而提升了终端与次基站建立连接的灵活度，也能够从一定程度上满足终端业务的服务质量要求。
优选地，协商消息中携带的主基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量，或者邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量还可以包括：对应于所有终端状态的一个次基站增加/释放门限偏移量，或者对应于一个或者一组终端状态的一个次基站增加/释放门限偏移量；或者分别对应于多个或者多组终端状态的多个次基站增加/释放门限偏移量。
优选地，为了避免主基站发送给邻区基站的次基站增加/释放门限或次基站增加/释放门限偏移量不被邻区基站支持，而导致邻区基站与终端的连接建立失败的问题，在主基站发送协商消息至邻区基站之后，邻区基站可以向主基站发送设置为指示邻区基站是否允许协商消息所指示的邻区基站的次基站增加/释放门限偏移量的协商响应消息至主基站，主基站接收邻区基站响应于协商消息的协商响应消息，并根据该协商响应消息确定邻区基站允许协商消息所指示的邻区基站的次基站增加/释放门限偏移量的情况下，邻区基站再根据协商消息中的邻区基站的次基站增加/释放门限偏移量对其次基站增加/释放门限当前值进行调整，调整后的值将用于后续的邻区基站与终端的连接的建立/拆除。
优选地，协商响应消息中携带有以下至少之一的信息：邻区基站是否允许邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量的标识；邻区基站针对邻区基站的小区的次基站增加/释放门限当前值；邻区基站允许的邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量的范围。例如，以邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量的范围为例，主基站在接收到上述协商响应消息之后，在协商响应消息中的邻区基站是否允许邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量的标识为拒绝的情况下，判断在之前的协商消息中所指示的邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量是否落入协商响应消息中所指示的邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量的范围中，如果不是，则主基站可以调整邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量使之落入协商响应消息中所指示的邻区基站针对邻区基站的小区的次基站增加/释放门限当前值的偏移量的范围内，尝试重新发送新的协商消息，以重新协商次基站增加/释放门限。
优选地，主基站与邻区基站之间设置为次基站增加/释放门限的协商的消息可以采用现有的消息，也可以采用新增的消息。例如，协商消息可以是新增的请求消息，或 者现有的移动性变更请求消息；协商响应消息可以是新增的响应消息，或者现有的移动性变更成功/失败响应消息。
本实施例还提供了一种双连接拆建装置，该装置位于主基站中。该装置设置为实现上述双连接拆建方法。图3是根据本发明实施例的双连接拆建装置的结构示意图一，如图3所示，该装置包括：第一确定模块32和第一拆建模块34，其中，第一确定模块32，设置为确定终端所接入的主基站当前配置的次基站增加/释放门限；第一拆建模块34耦合至第一确定模块32，设置为根据次基站增加/释放门限，建立/拆除邻区基站与终端的连接。
上述的终端为支持双连接的移动设备，也被称为用户设备、移动用户设备、移动终端等。
需要说明的是，本发明的实施例中所涉及到的模块、单元可以通过软件的方式实现，也可以通过硬件的方式来实现。本实施例中的所描述的模块、单元也可以设置在处理器中，例如，可以描述为：一种处理器包括第一确定模块32和第一拆建模块34。其中，这些模块的名称在某种情况下并不构成对该模块本身的限定，例如，第一确定模块32还可以被描述为“设置为确定终端所接入的主基站当前配置的次基站增加/释放门限的模块”。
并且，装置实施例中描述的双连接拆建装置对应于上述的方法实施例，其具体的实现过程在方法实施例中已经进行过详细说明，在此不再赘述。

本优选实施例提供了一种双连接时的SeNB增加/释放的优化方法，该方法涉及通讯领域，具体涉及一种双连接时的SeNB增加/释放的优化方法。
在本优选实施例中，为了实现SeNB的增加/释放，在进行双连接时，MeNB与SeNB维护SeNB增加/释放门限，其中，所维护的SeNB增加/释放门限为一针对SeNB中某个Cell的独立的门限，或为与小区切换门限的一个偏移量、或为预先配置的SeNB增加/释放门限的一个偏移量。
