Description

基站组网方法和装置、计算机存储介质 技术领域
本发明涉及无线通讯领域，尤其涉及一种基站组网方法和装置、计算机存储介质。
背景技术
在长期演进(LTE，Long Term Evolution)中，以物理小区标识(PCI，Physical Cell Identifier)来区分不同小区的无线信号。LTE系统提供了504个PCI，和时分同步码分多址(TD-SCDMA，Time Division-Synchronous Code Division Multiple Access)系统的128个扰码概念类似，网管配置时，为小区配置0～503之间的一个号码。
现代的无线通讯领域在原有大基站，即宏基站的规划组网的基础上，对分布式小基站，即微站的组网的需求也在不断的增加，微站的使用带来了用户体验的上升，基站建设速度快、方便等优点。每个宏基站覆盖区域内有多个微站，各个微站之间相互距离较远，而当宏基站自动配置的时候，就会导致各个微站都选择了一样的PCI和频点。然而根据组网的普遍规则，一个基站最好避免同时配置多个一样的频点和PCI的邻区，否则会出现PCI混淆导致切换基站失败的情况。
上述内容仅用于辅助理解本发明的技术方案，并不代表承认上述内容是现有技术。

具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例的主要解决方案是：当网关接收到宏基站的切换请求时，判断所述宏基站邻区是否存在PCI混淆问题；当存在PCI混淆问题，且网关管理的目标基站的预留资源充足时，选取预留资源；向至少一个目标基站发送所述切换请求，所述切换请求携带所选取的预留资源的编号，以供接收到所述切换请求的目标基站根据所述编号回复切换响应给所述网关；网关接收所述切换响应，根据所述切换响应发送预设消息给所述宏基站，以供用户设备进行切换。通过当宏基站邻区出现PCI混淆问题时，向至少一个目标基站发送预设切换请求，并统一分配所述目标基站的预留资源，对所述预留资源进行编号。解决了当基站出现一样的频点和PCI邻区时，出现PCI混淆导致切换基站失败的问题，使大量宏基站的LTE组网不需要做改动，即可提升宏微组网的移动性能指标。
由于在现有技术中，当基站出现一样的频点和PCI邻区时，就会出现PCI混淆导致切换基站失败的问题。
基于上述问题，本发明实施例提供一种基站组网方法。
参照图1，图1为本发明基站组网方法第一实施例的流程示意图。
在本实施例中，所述基站组网方法包括：
步骤S10，当网关接收到宏基站的切换请求时，判断所述宏基站邻区是否存在物理小区标识PCI混淆问题；
步骤S20，当存在PCI混淆问题，且网关管理的目标基站的预留资源充足时，选取预留资源；
步骤S30，向至少一个目标基站发送所述切换请求，所述切换请求携带所选取的预留资源的编号，以供接收到所述切换请求的目标基站根据所述 编号回复切换响应给所述网关；
每个宏基站都会携带以供用户设备(UE，User Equipment)进行切换的家庭演进基站(HeNB，Home evolved Node B)，在本实施例中，所述宏基站携带的供UE切换目标基站为HeNB1或者HeNB2，HeNB1和HeNB2 PCI混淆。HeNB1和HeNB2都预留了N份相同的切换准备资源，如小区无线网络临时标识(C-RNTI，Cell Radio Network Temporary Identifier)，随机接入Preamble等。并对每一份预留的准备资源进行编号，N的大小和预留的准备资源均可根据需要来配置。与网关连接的所有目标基站的预留的切换准备资源保持一致，以供所述网关在PCI混淆的场景下进行统一份分配。所述网关优选为家庭基站网关HeNB GW。
UE在宏基站覆盖范围内测量到HeNB1信号较好，则将所述HeNB1的PCI上报给所述宏基站，所述宏基站接收后，向HeNB GW发送切换请求。HeNB GW接收所述宏基站的切换请求，判断所述宏基站邻区是否存在PCI混淆问题。所述切换请求为X2切换请求。所述X2接口是e-NodeB之间的互连接口，支持数据和信令的直接传输。
当所述宏基站邻区存在PCI混淆问题时，即宏基站邻区HeNB1和HeNB2同时配置了一样的频点和PCI，HeNB1和HeNB2混淆了。当所述目标基站的预留准备资源充足，足够完成此次切换流程时，HeNB GW从预留的多份切换准备资源中选择一份预留资源，并将所述预留资源的编号存放在X2切换请求中，通过所述X2切换请求带给所述目标基站HeNB1和HeNB2。所述目标基站HeNB1和HeNB2根据所述X2切换请求中所携带的预留资源的编号，生成与所述编号对应的配置信息，并给所述HeNB GW回复切换响应。所述配置信息包括但不限于：C-RNTI，Preamble Index，Prach Mask Index，Cqi Pucch Resource Index，Cqi Pmi Config Index等。这样所有的目标基站回复的切换响应消息携带的内容，除了用户面的隧道端点标识 符(TEID，Tunnel Endpoint Identifier)和网络之间互连的协议(IP，Internet Protocol)地址，其它都是一致的。
步骤S40，网关接收所述切换响应，根据所述切换响应发送预设消息给所述宏基站，以供用户设备进行切换。
HeNB GW接收所述切换响应，且所述接收的全部切换响应都可以合并为一个信号时，即HeNB GW接收到HeNB1和HeNB2回复的切换响应，发送一个预设消息给宏基站，以供UE进行切换。所述预设消息为Handover Request Acknowledge，告诉所述宏基站目标基站HeNB1和HeNB2的切换准备工作已经完成，可以进行UE的切换了。其中，用户面的TEID和IP地址，有所述HeNB GW实现用户面汇聚功能，将不同的IP地址和TEID映射为一个统一的IP地址和TEID，发送给所述宏基站。所述宏基站发送X2 SN Status Transfer给UE所要切换到的基站，如所述UE要切换到的HeNB1中。当所述HeNB GW接收到所述X2 SN Status Transfer时，将所述X2 SN Status Transfer转发给多个目标HeNB，即转发给HeNB1和HeNB2。
本实施例通过当宏基站邻区出现PCI混淆问题时，向所有的目标基站发送预设切换请求，并统一分配所述目标基站的预留资源，对所述预留资源进行编号。解决了当基站出现一样的频点和PCI邻区时，出现PCI混淆导致切换基站失败的问题，使大量宏基站的LTE组网不需要做改动，即可提升宏微组网的移动性能指标。
参照图2，图2为本发明基站组网方法第二实施例的流程示意图。基于第一实施例提出本发明基站组网方法的第二实施例。在本实施例中，所述步骤S10之前，还包括：
步骤S50，网关和宏基站建立链路，通过所述链路获知所述宏基站的邻区信息。
网关和宏基站建立链路，即HeNB GW和宏基站建立X2链路，通过 X2接口获取到所述宏基站小区的邻区信息，得知所述宏基站邻区存在PCI混淆，并且存在所述PCI混淆的小区中HeNB1、HeNB2和所述HeNB GW建立了链路，如S1链路。HeNB GW也可以通过直接和HeNB1、HeNB2进行X2连接，获得存在PCI混淆的目标基站的信息。
在所述步骤S40之后，还包括：
步骤S60，当切换成功后，网关向接收过所述切换请求的其它目标基站发送切换取消消息，以释放所述其它目标基站的资源。
当用户设备成功切换到与其距离比较近，信号比较好的目标基站时。如当用户设备切换到HeNB1中时，在当前场景下，所述HeNB1距离所述用户设备比较近，信号较好。所述HeNB1发送S1 Path Switch Request给HeNB GW，当所述HeNB GW接收到所述S1 Path Switch Request后，一方面将所述S1 Path Switch Request发送给移动管理实体(MME，Mobility Management Entity)，另一方面向其它接收过X2 Handover Request的HeNB发送X2 Handover Cancel。即HeNB GW向接收过所述X2切换请求的HeNB2发送X2 Handover Cancel切换取消消息，释放HeNB2的资源，并在等待预设时间段后，释放本次切换时分配的预留资源，以用于后续PCI混淆时的切换。所述预设时间段为十秒钟以内，本发明实施例中，预设时间设置为5秒，即在等待5秒之后，HeNB GW释放本次切换时分配的预留资源。所述预设时间具体为多少可以根据当前的网络、运行速率等因素进行设置。
当目标基站在UE完成切换后，进行小区内的切换，所述小区内基站的切换使用非预留资源，并释放占用的预留资源。如果在进行小区切换时发现非预留资源已经不足，则将用户设备通过切换或者重定向的方式迁移到一个合适的邻区，最终释放其占用的资源，从而保证下次PCI混淆时预留的切换资源可以继续使用。而且HeNB GW会向接收过所述预设切换请求 的其它目标基站发送切换取消消息，以释放所述其它目标基站的资源。
本实施例通过当切换完成后，释放各个基站此次切换操作占用的预留资源，进而保证下次PCI混淆时预留的切换资源能继续使用，提高了资源的利用率。
参照图3，图3为本发明基站组网方法第三实施例的流程示意图。基于第一实施例提出本发明基站组网方法的第三实施例。在本实施例中，所述步骤S10之后，还包括：
步骤S70，当存在PCI混淆问题，且网关管理的目标基站的预留资源不足以完成切换操作时，发送切换准备失败的消息给宏基站，结束切换流程。
当目标基站HeNB1和HeNB2存在PCI混淆问题时，在网关管理的目标基站HeNB1和HeNB2的预留资源不足以完成此次切换操作的情况下，网关发送切换准备失败的消息给宏基站，即HeNB GW发送切换准备失败的消息给所述宏基站，结束此次切换流程。
本实施例通过当存在PCI混淆问题，且目标基站的预留资源不足以完成切换操作时，发送切换准备失败的消息给宏基站，结束切换流程。实现了在目标基站资源缺乏的情况下，及时结束切换流程，有效地提高了用户设备的切换效率。
参照图4，图4为本发明基站组网方法第四实施例的流程示意图。基于第一实施例提出本发明基站组网方法的第四实施例。在本实施例中，所述网关接收所述切换响应之后，还包括：
步骤S80，判断是否存在无法合并的切换响应；
步骤S90，当存在无法合并的切换响应时，向所述无法合并的切换响应对应的目标基站发送切换取消消息；
步骤S110，当不存在无法合并的切换响应时，合并所述切换响应，执行步骤：根据所述切换响应发送预设消息给所述宏基站，以供用户设备进 行切换。
网关接收所述切换响应，判断是否存在无法合并的切换响应，即HeNB GW接收HeNB1返回的切换响应和HeNB2返回的切换响应是否可以合并为一个切换响应，当所述切换响应无法合并时，即HeNB1和HeNB2返回的切换响应无法合并成一个切换响应时，向所述无法合并的切换响应对应的目标基站发送切换取消消息，以供所述目标基站取消后续操作，结束切换流程。当不存在无法合并的切换响应时，合并所述切换响应，即将HeNB1回复的切换响应和HeNB2回复的切换响应合并成一个切换响应，根据所述切换响应发送预设消息给所述宏基站，以供用户设备进行切换。
本实施例通过网关接收所述切换响应，当存在切换响应无法合并的目标基站时，向所述无法合并的切换响应对应的目标基站发送切换取消消息。实现了在目标基站返回的切换响应无法合并的情况下，及时结束切换流程，有效地提高了用户设备的切换效率。

每个宏基站都会携带以供用户设备(UE，User Equipment，)进行切换的家庭演进基站(HeNB，Home evolved Node B，)，在本实施例中，所述宏 基站携带的供UE切换目标基站为HeNB1或者HeNB2，HeNB1和HeNB2PCI混淆。HeNB1和HeNB2都预留了N份相同的切换准备资源，如小区无线网络临时标识(C-RNTI，Cell Radio Network Temporary Identifier)，随机接入Preamble等。并对每一份预留的准备资源进行编号，N的大小和预留的准备资源均可根据需要来配置。与网关连接的所有目标基站的预留的切换准备资源保持一致，以供所述网关在PCI混淆的场景下进行统一份分配。所述网关优选为家庭基站网关HeNB GW。
UE在宏基站覆盖范围内测量到HeNB1信号较好，则将所述HeNB1的PCI上报给所述宏基站，所述宏基站接收后，向HeNB GW发送切换请求。HeNB GW接收所述宏基站的切换请求，判断所述宏基站邻区是否存在PCI混淆问题。所述切换请求为X2切换请求。所述X2接口是e-NodeB之间的互连接口，支持数据和信令的直接传输。
当所述宏基站邻区存在PCI混淆问题时，即宏基站邻区HeNB1和HeNB2同时配置了一样的频点和PCI，HeNB1和HeNB2混淆了。当所述目标基站的预留准备资源充足，足够完成此次切换流程时，HeNB GW从预留的多份切换准备资源中选择一份预留资源，并将所述预留资源的编号存放在X2切换请求中，通过所述X2切换请求带给所述目标基站HeNB1和HeNB2。所述目标基站HeNB1和HeNB2根据所述X2切换请求中所携带的预留资源的编号，生成与所述编号对应的配置信息，并给所述HeNB GW回复切换响应。所述配置信息包括但不限于：C-RNTI，Preamble Index，Prach Mask Index，Cqi Pucch Resource Index，Cqi Pmi Config Index等。这样所有的目标基站回复的切换响应消息携带的内容，除了用户面的隧道端点标识符(TEID，Tunnel Endpoint Identifier)和网络之间互连的协议(IP，Internet Protocol)地址，其它都是一致的。
第二发送模块40，配置为网关接收所述切换响应，根据所述切换响应 发送预设消息给所述宏基站，以供用户设备进行切换。
HeNB GW接收所述切换响应，且所述接收的全部切换响应都可以合并为一个信号时，即HeNB GW接收到HeNB1和HeNB2回复的切换响应，发送一个预设消息给宏基站，以供UE进行切换。所述预设消息为Handover Request Acknowledge，告诉所述宏基站目标基站HeNB1和HeNB2的切换准备工作已经完成，可以进行UE的切换了。其中，用户面的TEID和IP地址，有所述HeNB GW实现用户面汇聚功能，将不同的IP地址和TEID映射为一个统一的IP地址和TEID，发送给所述宏基站。所述宏基站发送X2 SN Status Transfer给UE所要切换到的基站，如所述UE要切换到的HeNB1中。当所述HeNB GW接收到所述X2 SN Status Transfer时，将所述X2 SN Status Transfer转发给多个目标HeNB，即转发给HeNB1和HeNB2。
本实施例通过当宏基站邻区出现PCI混淆问题时，向所有的目标基站发送预设切换请求，并统一分配所述目标基站的预留资源，对所述预留资源进行编号。解决了当基站出现一样的频点和PCI邻区时，出现PCI混淆导致切换基站失败的问题，使大量宏基站的LTE组网不需要做改动，即可提升宏微组网的移动性能指标。
