Description

连接建立方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及连接建立方法及装置。
背景技术
移动互联网、物联网、以及其他业务应用的迅猛发展已经成为推动第五代移动通信技术(5G)发展的主要驱动力。他们迫切要求5G具有媲美光纤的接入速率、千亿设备的连接能力、完美的实时体验、以及随时随地的无线宽带接入能力。此外，能耗效率、频谱效率和峰值速率等重要指标也需要在5G***设计时综合考虑。在2013年成立了IMT-2020(5G)推进组来推动5G技术的发展。根据国际整体情况，预计2015年将形成5G愿景、关键能力需求及频谱规划，之后将启动5G标准化工作，并在2020年后开始商用。国际标准方面，LTE-Advanced的技术标准主要在3GPP国际标准化组织制订。业界初步认为在3GPP R14阶段将启动面向5G的标准研究工作。
在未来的移动网络中，业务量需求会不断提高、终端数目和种类也不断爆发式增长。作为5G的重要场景和技术手段之一，超密集网络(Ultra Dense Network，简称为UDN)正受到越来越多的关注。当现有的LTE-A技术应用于超密集网络中，各小区公共参考信号间的干扰随着小区数量的增加越来越严重。为了避开这个干扰，UDN中经常需要进行小区间的协调开关，即在某段时间关闭部分小区基站来减少干扰，而在另一段时间关闭另一部分小区基站。为了协调和降低各小区的干扰，可以使用理想的回传链路来实时交互业务流量信息，并根据业务流量信息进行各小区开关的集中控制。但是，理想的回传链路大大增加了回传网络的部署成本，所有在实际的网络部署中很难在所有覆盖场景下全部实现理想回传。
图1是相关技术中超密集网络中开关工作模式的示意图，如图1所示，宏基站覆盖可以提供较大范围的无线链路支持，但由于传输距离较远导致链路的质量受到一定的影响；各小基站为终端提供更加优良的无线链路，用于增强网络的容量。但是，随着小小区覆盖的密集化，小基站的分布更加密集和无序，小小区间的干扰变得十分复杂，产生了更多的边缘用户，严重限制了整个UDN网络的整体吞吐量。为了在回传链路非理想的情况下协调各个小区之间的干扰，经常采用按图样进行小区开关的干扰协调模式(以下简称为图样开关模式)，即每个小区按照一定的图样进行小区信号的开关，从而降低各小区之间的干扰。图1的右侧显示了各小小区的开关图样示例，可以 看出，不同小小区的开关图样是不同的，但它们在时间上是同步的，且都由多个单位时间段组成。在每个单位时间段，各小区可以根据图样决定自己的开关状态。具体的开关图样可以由中心节点统一分配，也可以由各小区和其相邻小区根据检测到的干扰状况通过协商产生。图样中进行小区开关的单位时间段可以从一个1毫秒(ms)子帧到多个10ms的无线帧，整个图样的控制时长(即整个开关图样周期)取决于开关图样的实际长度，可以从几ms到几十、几百、几千ms、甚至更长。这样，各个小区间的相关控制信息的交互可以根据回传链路的实际时延状况来进行，并产生相应长度的非周期性或周期性的开关控制图样。
虽然图样开关模式能够在回传链路非理想的情况下有效的进行干扰协调，但也在一定程度上限制了用户的峰值速率。这是因为小区在一部分子帧段内处于关闭OFF状态，用户无法利用这部分子帧进行数据传送。为了克服这个缺点，可以采用多连接的数据传送方案，即用户同时和相邻的多个小区基站建立多个连接，在不同的开关单位时间使用不同的连接进行数据传输。这样，该用户就可以利用所有子帧进行数据传输，大大提高了传输的峰值速率。并且，由于UDN的各小区使用的是相同频点的信道，这种多连接的通信方式只需要使用一套无线设备就可以实现，没有增加用户终端的成本，这和3GPP讨论的异频双连接方案完全不同。然而，以前讨论的多连接数据传输方法并没有考虑在图样开关模式下的具体实现方法。
针对相关技术中不能在开关模式下建立新连接问题，目前尚未提出有效的解决方案。

下面结合可选实施例对本发明实施例进行进一步说明。
图7是根据本发明实施例的用户进行多连接通信的示意图，如图7所示，虽然图样开关模式能够在回传链路非理想的情况下有效的进行干扰协调，但也在一定程度上限制了用户的峰值速率。这是因为每个小区都在一部分子帧段内处于关闭状态，用户无法利用这部分子帧进行数据传送。为了克服这个缺点，可以采用多连接的数据传送方案，即用户同时和相邻的多个小区基站建立多个连接，在不同的开关单位时间使用不同的连接进行数据传输。图中用户A同时和基站2、3、4建立了多个连接。由于基站2，3，4在相同时间段开关状态不同，用户A可以在不同时间利用不同的连接进行数据传输。这样，该用户在所有子帧内都可以进行数据传输，大大提高了单用户传输的峰值速率。并且，由于UDN的各小区使用的是相同频点的信道，这种多连接时分的通信方式只需要使用一套无线设备就可以实现，没有增加用户终端的成本。
图8是根据相关技术中的用户建立连接的流程图，如图8所示，在传统LTE/LTE-A***中，用户建立连接包括以下步骤：
步骤(1)，随机接入前导；
步骤(2)，随机接入响应；

本可选实施例是针对如何在图样开关模式下，提出的多连接的建立方法，以上述步骤为基础，在图样开关模式下提供一种多连接的建立方法，实现图样开关模式下的多连接通信，提升用户峰值速率。为此，提供了一种图样开关模式下的新连接的建立方法，该方法可以充分利用已有连接来和其他一个或多个传送点(TP)建立一个或多个新连接。为了简化描述，假设用户已经在一个小区用传统方法和基站建立了一个或多个已有连接。图9是根据本发明实施例的用户接入目标传送点的流程图一，如图9所示，包括以下内容：
步骤S902，用户和网络进行业务信息的交互，网络侧设备进行新TP连接建立判决和目标TP选择后，通知已连基站新连接建立决定和目标TP标识，用户基于业务需求向网络侧设备发送新的业务请求或业务更新请求后，网络侧设备进行一定的分析，判断是否需要为该用户和其他传送点建立新的连接。如果需要，网络侧设备将新TP连接决定和所选择的目标传送点标识通知已连基站；
S904，新TP连接建立相关信息交互；
S906，新TP连接建立通知，基站收到该信息后，和目标TP交互信息后，发送“新TP连接建立通知”消息给用户，通知其在某个或多个子帧中保持工作状态，并指示进行新连接建立；
S908，新TP连接建立确认，用户发送“新TP连接建立确认”消息，确认“新TP连接建立通知”消息的成功接收，并报告基站建立新连接所需的用户侧信息，其中包括传统接入方式中用户发送的各种接入信令消息中可以包含的信息；
S910，新TP连接建立相关信息交互，基站和目标传送点TP进一步交互信息，传输和确认新连接的各项参数；
S912，用户和目标传送点进行新TP连接建立，用户按“新TP连接建立通知”消息中的指示进行下一步的新连接建立过程。
需要说明的是，“新TP连接建立通知”消息和“新TP连接建立确认”消息中的信息也可以用LTE中已经存在的无线资源控制(RRC)消息传送，例如RRC连接重 配置消息和RRC连接重配置完成消息。“新TP连接建立通知”消息可以用“开始步骤号”来指示用户从传统连接建立过程图8所示的步骤中的哪一步开始直接和目标TP进行交互。为了使用户顺利进行新连接的建立，基站需要提前和目标TP进行交互，提供建立新连接所需的信息，并从目标TP处获得建立新连接所需的相关的参数，然后通过“新TP连接建立通知”消息通知用户。
用户可以直接分析业务需求后发送新TP连接请求，其中包含和其他传送点建立新的连接的请求的指示和相关信息，用户直接根据业务需求或本地测量结果进行新TP连接判决和目标TP选择。图10是根据本发明实施例的用户接入目标传送点的流程图二，如图10所示，包括以下步骤：

通过本可选实施例，能够在开关模式下顺利进行新连接的建立。通过“新TP连接建立通知”消息，基站能通知用户在某个或多个OFF子帧中保持工作状态，而不是按先前的方式关闭收发器，从而保证了其与目标TP的交互。其次，本发明通过指示新连接建立方法，使通信***能够灵活的进行新连接的建立，充分利用基站侧信息和已有的用户连接，减少新连接建立的延迟。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
上述的本发明实施例，应用于通信领域，解决了相关技术中不能在开关模式下建立新连接问题，进而达到了灵活建立新连接的效果。
