Description

频带共享方法、设备和系统、相关计算机存储介质 技术领域
本发明涉及无线通讯领域，尤其涉及一种频带共享方法、设备和系统、相关计算机存储介质。

根据国际电信同盟(ITU，International Telecommunications Union)的预测，随着用户移动通信需求的不断攀升，到2020年，移动通信业务更是有可能出现超过500倍，甚至到达1000倍的增长，因此无线通讯业内正在探讨各种可能的技术，以扩容网络能力，增强网络覆盖，从而满足移动业务爆发式增长的态势。
其中一种可能的方向为让多种蜂窝无线通信技术或者多个运营商部署的一种蜂窝无线通信技术之间共享使用相同的频带资源，从而打破传统蜂窝无线通信技术在授权频带(licensed spectrum/licensed band)上通过完全独占一个授权频带或者在一定时间、一定区域内独占一个授权频带的方式，以提高频带利用率，扩容网络能力，增强网络覆盖。但是多种蜂窝无线通信技术或者多个运营商部署的一种蜂窝无线通信技术很有可能会同一时间在相同的频带上发起数据传输，从而导致多种蜂窝无线通信技术或者多个运营商部署的一种蜂窝无线通信技术之间发生相互的干扰或者冲突的情况；此外，当可共享使用的频带资源上已经有在用的非蜂窝无线通信系统部署的时候，如无线本地局域网(WLAN，Wireless Local Area Network)、无线个域网(WPAN，Wireless Personal Area Network)、全球微波接入互操作性系统(WiMax，World Interoperability for Microwave Access)等，将蜂窝无线通信技术部署到这些可共享使用的频带资源上也会造成对这些在用的非蜂窝无线通信系统的干扰。因此，有必要寻求技术方案解决可共享使用的频带资源上的多种无线通信技术(包括蜂窝无线通信技术之间以及蜂窝无线通信技术与非蜂窝无线通信技术之间)或者多个运营商部署的同种无线通信技术之间的干扰的问题。

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。
需要说明的是，本发明实施例中的实施例仅用于说明本发明所提出的频带共享方法，但并不限制本发明提出的频带共享方法的使用范畴，可以理解的，本发明实施例提出的方案不仅可以适用于长期演进技术(LTE，Long  Term Evolution)技术的其他类型的小区，比如宏小区；还可以适用于其他传统无线通信技术的各类型的小区，比如通用移动通信系统(UMTS，Universal Mobile Telecommunications System)等。此外，本发明实施例中的频带共享资源，是指多种无线通信技术或者多个运营商都可以共享使用的频带资源，并不限定和考虑共享的频带资源在本发明申请递交的国家或者地区的管控属性，具体频带可以是本发明申请递交的国家或者地区授权使用的频带，也可以是不需要本发明申请递交的国家或者地区授权的、可免费使用的频带。
在本发明实施例中，以单个以及多个运营商为例进行说明，分别如图1和图2所示的场景所示。
图1表示本发明实施例的技术方案应用在单个运营商的场景；其中，宏基站(100)部署的宏小区(101)的覆盖范围如实线圆所示，斜线填充的小小区部署在宏小区(101)覆盖范围内，小小区通过部署低功率站点(LPN，Low Power Node)实现，而在本发明实施例中LPN也可称为小基站，以小小区1(102)为例，小小区1(102)与宏基站(100)之间可以以无线或者有线的方式通过连接C100进行连接，也可以与中心控制单元(104)之间以无线或者有线的方式通过连接C101进行连接；栅格填充的小小区与宏基站(100)由同一个运营商部署，部署在没有在宏小区(101)覆盖的范围内，以小小区2(103)为例，小小区2(103)与其附近的宏基站(100)之间可以以有线的方式通过连接C102进行连接，也可以与中心控制单元(104)之间以无线或者有线的方式通过连接C103进行连接。
图2表示本发明实施例的技术方案应用在多个运营商的场景，以两个不同的运营商A和B为例；运营商A的宏基站1(200)所部属的宏小区1(201)的覆盖范围与运营商B的宏基站2(202)所部属的宏小区2(203)的覆盖范围有重叠的区域；斜线填充的小小区为运营商A部署的小小区，以下以小小区X(205)为例，小小区X(205)通过连接C200以无线或者有线的方式与宏基站1连接，或者小小区X(205)通过连接C201以无线或者有线的方式与中心控制单元204连接。栅格填充的小小区为运营商B部署的小小区，以下以小小区Y(206)为例，小小区Y(206)通过连接C203以无线或者有线的方式与宏基站2连接，或者小小区Y(206)通过连接C204以无线或者有线的方式与中心控制单元204连接。此外，宏基站1(200)与宏基站2(202)可以通过连接C205进行连接，而且宏基站1(200)与宏基站2(202)分别可以以无线或者有线的方式通过连接C206和C207与中心控制单元(204)进行连接。小小区X(205)和小小区Y(206)均处于宏小区1(201)与宏小区2(203)的重叠的覆盖范围区域。
在对上述两个场景的描述中，无线的连接方式可以包括微波、毫米波等方式进行连接，或者小小区在宏基站所支持的频率上与宏基站进行通信，例如在图1中，小小区1(101)可以在频率1上与宏基站1(100)进行LTE 制式的通信；有线的连接方式可以包括通过光纤、电缆等方式进行连接。较佳的，中心控制单元可以通过与小小区之间的直接接口与小小区进行信息交互；也可以利用中心控制单元与小小区之间的第三节点(例如如图2的宏基站1)中转，通过间接接口与小小区进行信息交互。本发明实施例对此不作限定。
需要说明的是，在本发明实施例中，中心控制单元用于负责对一定区域内的共享频带资源进行分配，中心控制单元具体负责进行共享频带资源分配的区域由网络部署拓扑结构、网络运维策略等因素决定。以图1和图2示例的场景为例，如图1所示的中心控制单元104，可以负责为图1中单一运营商部署的斜线填充的小小区和栅格填充的小小区分配资源；如图2所示的中心控制单元204，可以负责为图2中运营商A部署的斜线填充的小小区和运营商B部署的栅格填充的小小区分配资源。具体的，中心控制单元可以是个独立的网络单元，也可以是集成在现有网络节点上的逻辑单元，本发明实施例对此不作任何限定。
参见图3，为本发明实施例提供的一种频带共享方法，可以应用在图1和图2所示的场景中，该方法可以包括：
S301：第一网络设备接收由至少一个第二网络设备发送的频带共享辅助信息；
示例性的，第一网络设备可以是如图1和图2所示的宏基站，也可以是如图1和图2所示的中心控制单元；
相应的，当第一网络设备为宏基站的时候，第二网络设备可以是宏基站覆盖范围内所部署的小基站或者是宏基站覆盖范围外靠近宏基站的小基站；比如在图1中，第一网络设备可以是宏基站(100)，而第二网络设备则可以是图1中斜线填充的小基站或者是图1中栅格填充的小基站。在图2中，第一网络设备可以是运营商A的宏基站1(200)，也可以是运营商B的宏基站2(202)；相应的，当第一网络设备是宏基站1(200)的时候，第二网络设备为图2中斜线填充的小基站；当第一网络设备是宏基站2(202)的时候，第二网络设备为图2中栅格填充的小基站。
当第一网络设备为中心控制单元的时候，第二网络设备则是由中心控制单元所负责进行共享频带资源分配的小基站；比如，在图1和图2中，第一网络设备均可以是中心控制单元，那么第二网络设备不仅可以是斜线填充的小基站，也可以是栅格填充的小基站；结合图2的应用场景可知，在图2中，中心控制单元所对应的第二网络设备可以是多个运营商所部署的小基站。
可选的，频带共享辅助信息可以包括第二网络设备的射频参数，以第二网络设备仅配置一个小小区为例，第二网络设备的射频参数至少包括第二网络设备的频率(也可称之为信道，如无特殊说明以下说明书中均称之为频率)；优选的，还可以包括第二网络设备为该小区设置的物理小区标识 (PCI，Physical-layer Cell Identity)。射频参数由第二网络设备确定，具体的第二网络设备通过监听周围第二网络设备的射频参数后确定自身的射频参数。比如第二网络设备可以选择没有被周围第二网络设备使用的频率或者当第二网络设备所支持的频率均被周围的第二网络设备使用时，则第二网络设备将选择一个频率，但该频率可以是被周围最少网络设备使用的频率，也可以是被周围网络设备使用但来自周围网络设备的信号强度最小的频率等，然后第二网络设备在该频率上确定一个未被周围的第二网络设备使用的PCI，从而可以使得第二网络设备与周围共享使用频率的同系统的第二网络设备之间干扰最小。
可选的，频带共享辅助信息可以包括第二网络设备的位置参数，位置参数由第二网络设备通过相关的定位技术定位获得，比如第二网络设备具备全球定位系统(GPS，Global Positioning System)功能，或观察到达时间差(OTDOA，Observed Time Difference of Arrival)，从而获知第二网络设备的位置参数；或者第二网络设备有后向连接的话，第二网络设备的位置参数即为后向连接的宽带连接信息，比如宽带接入点信息；或者当作为第二网络设备的LPN与无线保真(Wi-Fi，Wireless Fidelity)接入点集成到同一装置时，第二网络设备的位置参数即与该第二网络设备集成在同一装置中的Wi-Fi接入点的位置信息等，本发明实施例对此不再赘述。
此外，频带共享辅助信息也可以包括第二网络设备的位置参数和射频参数，本发明实施例对此不再赘述。
S302：所述第一网络设备根据所述频带共享辅助信息为所述至少一个第二网络设备配置对应的频带共享参数；
示例性的，所述频带共享参数用于所述第二网络设备根据所述频带共享参数使用共享频带资源；根据S301中所述频带共享辅助信息具有不同类型的参数，因此，第一网络设备也相应的通过不同的方法为所述至少一个第二网络设备配置对应的频带共享参数。
可选的，当所述频带共享辅助信息包括第二网络设备的射频参数，比如包括所述第二网络设备的频率，优选的，还包括所述第二网络设备的PCI的时候；如图4所示，S302的具体实现过程为：
S302-1：所述第一网络设备为所述频带共享辅助信息中的频率相同的第二网络设备配置相同的第一使用时间，所述第一使用时间为指示所述第二网络设备使用共享频带资源的时间。所述第二网络设备可以只在第一使用时间内进行开启或者只在第一使用时间内接收和发送信号，这样可以避免第二网络设备在不同时间连续占用该频率而导致其他使用该频率的异系统站点或设备一直无法使用该频率，从而避免对这些异系统站点或设备的正常通信产生干扰。
可以理解的，所述为频带共享辅助信息中频率相同的第二网络设备配置相同的第一使用时间，解决了第二网络设备与异系统站点或设备之间的 干扰。而所述第二网络设备之间的系统内干扰，则由第二网络设备确定自身的射频参数时解决。具体的当第二网络设备所支持的频率中有没有被周围第二网络设备使用的频率时，第二网络设备选择没有被周围第二网络设备使用的频率，通过异频布网解决系统内第二网络设备之间的干扰。而当第二网络设备所支持的频率均被周围的第二网络设备使用时，则选择一个被周围网络设备使用但来自周围网络设备的信号强度最小的频率等，然后第二网络设备在该频率上确定一个未被周围的第二网络设备使用的PCI，从而在射频参数确定阶段就使得第二网络设备与周围同频第二网络设备之间的干扰最小，此外在所述第一网络设备为所述频带共享辅助信息中的频率相同的第二网络设备配置相同的第一使用时间后，第一网络设备和第二网络设备还可以采用相关技术中的干扰协调方法进一步减少同频第二网络设备之间的干扰。
可选的，当所述频带共享辅助信息包括第二网络设备的位置参数的时候，如图4所示，S302的具体实现过程可以包括：
S302-21：第一网络设备根据所述频带共享辅助信息中的位置参数将所述至少一个第二网络设备进行分簇，分簇的原则可以是：同簇的第二网络设备具有相邻覆盖或者重叠覆盖。
对于分簇后的第二网络设备，如图4所示，第一网络设备可以根据预先设定的配置规则从S302-22a或S302-22b中的任选一种方式为同簇的第二网络设备配置频带共享参数，具体如下所述：
S302-22a：第一网络设备为同簇内的第二网络设备配置相同的频率、互不相同的PCI、以及相同的第二使用时间；
具体的，互不相同的PCI可以使得第二网络设备与其周围共享使用相同频率的其他第二网络设备之间的干扰最小，而所述第二使用时间为指示所述第二网络设备使用共享频带资源的时间。并且与第一使用时间类似的，为同簇的第二网络设备配置相同的第二使用时间可以使得使用相同频率的同簇内第二网络设备只在第二使用时间内开启或者只在第二使用时间内接收和发送信号，这样可以避免第二网络设备在不同时间连续占用该频率而导致其他使用该频率的异系统站点或设备一直无法使用该频率，从而避免对这些异系统站点或设备的正常通信产生干扰。
S302-22b：第一网络设备为同簇内的第二网络设备配置互不相同的频率，以及为同簇内配置了互不相同的频率的第二网络设备配置第三使用时间；
具体的，为同簇内的第二网络设备配置互不相同的频率可以使得第二网络设备与相邻或相近的同簇第二网络设备之间的干扰达到最小，需要说明的是，不同簇之间配置的频率是可以相同的，这是因为不同簇之间物理位置相距较远，大大降低了散射在自由空间中的电磁波功率，所以即使为不同簇配置了同一个频率，也不会在两个簇之间产生干扰，而且针对不同 簇使用相同的频率，可以更加有效地对有限的频率资源进行复用，从而提高了有限频率资源的使用效率；并且由于为同簇内的第二网络设备配置了互不相同的频率，因此所述各个第二网络设备的第三使用时间可以独立配置，而不会出现同簇内的第二网络设备在不同时间连续占用同一个频率而导致其他使用该频率的站点或设备一直无法使用该频率。
需要说明的是，当第二网络设备数量较多，多于可分配的频率时，所述第一网络设备可以结合S302-22a和S302-22b一起为第二网络设备配置频带共享参数。
较佳的，在图1所示的单运营商的场景中，无论第一网络设备是宏基站还是中心控制单元，均可以为图1中斜线填充的小小区以及栅格填充的小小区配置对应的频带共享参数，不需要考虑多个运营商部署的小小区之间的干扰。
但是在图2所示的多运营商的场景中，则需要考虑多个运营商部署的小小区之间的干扰。一方面，当第一网络设备是中心控制单元时，中心控制单元集中负责对区域内多个运营商部署的小基站分配共享频率资源，因此，中心控制单元在如前所述的对第二网络设备配置对应的频带共享参数的过程中，已经解决了多个运营商部署的小小区之间的干扰问题；另一方面，当第一网络设备是宏基站时，由于宏基站仅能接收本运营商所部署的第二网络设备发送的频带共享辅助信息，无法直接接收来自其他运营商所部署的第二网络设备发送的频带共享辅助信息，因此，当宏基站为第二网络设备配置对应的频带共享参数时，还需要考虑并解决与其他运营商所部属的第二网络设备之间的干扰，例如，在图2中，宏基站1(200)在为斜线填充的小基站配置对应的频带共享参数的时候，还需要考虑并解决与宏基站2(202)所部属的栅格填充的小基站之间的干扰，因此，当第一网络设备为宏基站的时候，本方法还可以包括：接收第三网络设备发送的频带共享协商信息；
可以理解的，接收第三网络设备发送的频带共享协商信息这一步骤可以在第一网络设备为第二网络设备配置频带共享参数之前的任何时候进行，本发明实施例对该步骤的执行时刻不作具体的限定。
需要说明的是，由于作为第一网络设备的宏基站在S302中根据频带共享辅助信息所具有的不同类型的参数，为第二网络设备配置不同的频带共享参数；因此，宏基站接收到第三网络设备发送的频带共享协商信息中也可以包括不同类型的信息，并且结合这些不同类型的信息分别通过不同的方式为第二网络设备配置频带共享参数，具体方法如下所述：
可选的，频带共享协商信息可以包括所述第一网络设备的运营商和所述第三网络设备的运营商通过协商确定互斥使用的频带或第三网络设备获取到的第四网络设备的频率以及第四使用时间；在本实施例中，第三网络设备可以是与第一网络设备不同运营商的宏基站，而第四网络设备则是作 为第三网络设备的宏基站所部署的小小区所在的小基站，结合图2所示，第三网络设备为宏基站2(202)，第四网络设备为小小区Y(206)所在的小基站；
相应的，当第一网络设备通过S302-1具体实现S302的时候，还可以包括：
当频带共享协商信息为第一网络设备的运营商和第三网络设备的运营商通过协商确定互斥使用的频带时，所述第一网络设备可以在自身的运营商所确定使用的频带上根据S302-1为所述第二网络设备配置频带共享参数，例如，第一网络设备所属的运营商和第三网络设备所属的运营商在某一区域内可以共享使用的频带为5470～5725MHz；而通过两者的协商，确定第一网络设备所属的运营商使用5470～5570MHz之间的频率，而第三网络设备所属的运营商使用5570～5725MHz之间的频率，因此，第一网络设备为第二网络设备配置的频率和第三网络设备为第四网络设备配置的频率是互斥使用的。
当频带共享协商信息为第三网络设备获取到的第四网络设备的频率以及第四使用时间时，当所述第四网络设备的频率与所述第二网络设备的频率相同时，所述第一网络设备将使用相同频率的第二网络设备的第一使用时间配置为所述第三网络设备获取到的所述使用相同频率的第四网络设备的第四使用时间。
可选的，频带共享协商信息可以包括第一网络设备的运营商和第三网络设备的运营商通过协商确定互斥使用的频带或第三网络设备获取到的第四网络设备的位置信息、频率、PCI、以及第五使用时间；
相应的，当第一网络设备通过S302-21和S302-22a具体实现S302的时候，还可以包括：
当频带共享协商信息为第一网络设备的运营商和第三网络设备的运营商通过协商确定互斥使用的频带时，所述第一网络设备可以在自身的运营商所确定使用的频带上根据S302-21和S302-22a为所述第二网络设备配置频带共享参数；
当频带共享协商信息为第三网络设备获取到的第四网络设备的位置信息、频率、PCI、以及第五使用时间时，所述第一网络设备根据所述第三网络设备获取到的第四网络设备的位置信息以及配置的频率确定所述第四网络设备处于任一簇所述第二网络设备的范围内且所述第四网络设备的频率与所述第一网络设备为该簇第二网络设备配置的频率相同；当所述第四网络设备处于任一簇所述第二网络设备的范围内且所述第四网络设备的频率与所述第一网络设备为该簇第二网络设备配置的频率相同的时候，所述第一网络设备将该簇第二网络设备的PCI配置为与所述第四网络设备配置的PCI互不相同，并将该簇第二网络设备的第二使用时间配置为所述第四网络设备配置的频率所对应的第五使用时间。
可选的，频带共享协商信息可以包括第一网络设备的运营商和第三网络设备的运营商通过协商确定互斥使用的频带或第三网络设备获取到的第四网络设备的位置信息和频率；
相应的，当第一网络设备通过S302-21和S302-22b具体实现S302的时候，还可以包括：
当频带共享协商信息为第一网络设备的运营商和第三网络设备的运营商通过协商确定互斥使用的频带时，所述第一网络设备可以在自身的运营商所确定使用的频带上根据S302-21和S302-22b为所述第二网络设备配置频带共享参数；
当频带共享协商信息为第三网络设备获取到的第四网络设备的位置信息和频率时，所述第一网络设备根据所述第三网络设备获取到的第四网络设备的位置信息确定所述第四网络设备处于任一簇所述第二网络设备的范围内；当所述第四网络设备处于任一簇所述第二网络设备的范围内的时候，所述第一网络设备根据所述第四网络设备的频率将该簇第二网络设备的频率配置为所述第四网络设备没有配置的频率。
需要说明的是，以上描述中的第一使用时间、第二使用时间、第三使用时间、第四使用时间和第五使用时间的具体形式可以为：周期性分配的一段连续时间，如图5A所示，以第一使用时间为例，第一使用时间以周期500a周期性出现，占用一个周期中所示的一段连续时间501a，如图5A中的阴影部分所示。第一网络设备或中心控制单元可以配置周期500a、第一使用时间时长501a以及第一使用时间起始时间502a等参数，以用于第二网络设备确定第一使用时间；
或者可以是单次分配使用的一段连续时间，同样以第一使用时间为例，第一网络设备或中心控制单元可以配置第一使用时间时长、第一使用时间起始时间等参数，以用于第二网络设备确定第一使用时间；
或者可以是周期性分配的离散时间，如图5B所示，以第一使用时间为例，第一使用时间以周期500b周期性出现，占用一个周期500b中所示的各段离散时间501b，如图5B中的阴影部分所示。第一网络设备或中心控制单元需要配置周期500b、第一使用时间起始时间502b、各段离散时间501b在周期内的位置等参数，以用于第二网络设备确定第一使用时间。
还需要说明的是，第一网络设备还可以从用户设备或者第二网络设备侧获取的同频段上在用系统(比如WLAN)的负荷、频率使用情况等信息为第二网络设备配置频带共享参数。
S303：所述第一网络设备将所述频带共享参数对应的发送至所述至少一个第二网络设备。
具体的，在如图1和2中，当第一网络设备为宏基站的时候，第一网络设备可以通过与第二网络设备之间的直接接口发送所述频带共享参数，
当第一网络设备为中心控制单元的时候，若第一网络设备与第二网络 设备之间缺乏直接接口，则第一网络设备可以通过间接接口例如其他网络设备转发述频带共享参数至第二网络设备。
需要说明的是，本发明实施例中的频率共享方法也适用于第二网络设备配置多个小小区的情况，在该情况下，多个小小区在本方案中实质可以理解为多个LPN，本方案的所有实施步骤中，逻辑上相当于第一网络设备分别在该多个LPN上实施各实施步骤。因此在以下所有实施步骤和实施例中第二网络设备均视为仅配置一个LPN，第二网络设备即等同于其配置的小区，在术语上不做进一步区分。
本发明实施例提供了一种频带共享方法，通过第一网络设备根据第二网络设备发送的频带共享辅助信息对第二网络设备的频带共享参数进行配置，避免了第二网络设备之间在共享频带资源的过程中发生干扰，也同时可以避免第二网络设备与已占用该共享频带资源的现有无线通信系统之间的干扰。
参见图6，为本发明实施例提供的另一种频带共享方法，该方法可以包括：
S601：第二网络设备获取自身的频带共享辅助信息；
可选的，频带共享辅助信息可以包括第二网络设备的射频参数，比如第二网络设备的频率，优选的，还可以包括所述第二网络设备的PCI；
具体的，第二网络设备可以通过监听周围的第二网络设备的射频参数来确定自身的射频参数，例如，第二网络设备可以选择没有被周围网络设备使用的频率；或者当第二网络设备所支持的频率均被周围的第二网络设备使用时，则第二网络设备将选择一个频率，但该频率可以是被周围最少网络设备使用的频率，也可以是被周围网络设备使用但来自周围网络设备的信号强度最小的频率等，然后第二网络设备在该频率上确定一个未被周围的第二网络设备使用的PCI，可以使得第二网络设备与周围共享使用频率的同系统的第二网络设备之间干扰最小。
更加具体的，第二网络设备监听周围的第二网络设备的方法可以是第二网络设备通过检测周围第二网络设备的同步信号，获知周围第二网络设备所使用的频率和PCI。在LTE系统中，第二网络设备可以通过检测主同步信号(PSS，Primary Synchronization Signal)和辅同步信号(SSS，Secondary Synchronization Signal)获知周围第二网络设备的频率和PCI，当然第二网络设备也可以检测其他物理层信号，比如发现信号等来获知周围第二网络设备的频率和PCI信息。本发明实施例对此不做具体限定。
可选的，频带共享辅助信息可以包括第二网络设备的位置参数；
具体的，第二网络设备的位置参数可以由第二网络设备通过相关的定位技术定位获得，比如第二网络设备具备GPS功能、OTDOA，从而获知第二网络设备的位置参数；或者第二网络设备有后向连接的话，第二网络设备的位置参数即为后向连接的宽带连接信息，比如宽带接入点信息；或者 当作为第二网络设备的LPN与Wi-Fi接入点集成到同一装置时，第二网络设备的位置参数即与该第二网络设备集成在同一装置中的Wi-Fi接入点的位置信息等，本发明实施例对此不再赘述。
此外，频带共享辅助信息也可以包括第二网络设备的位置参数和射频参数，本发明实施例对此不再赘述。
S602：第二网络设备向第一网络设备发送自身的频带共享辅助信息；
示例性的，频带共享辅助信息可以用于第一网络设备根据所述频带共享辅助信息来为所述第二网络设备配置相应的频带共享参数，具体的配置过程如前述实施例的S302中所述，在此不再赘述。
而频带共享参数是用于指示所述第二网络设备使用共享频带资源，从而避免所述第二网络设备与其他第二网络设备之间以及第二网络设备与现有的无线通信系统之间在使用共享频带资源过程中发生干扰。
S603：第二网络设备接收由第一网络设备发送的频带共享参数。
示例性的，第二网络设备在接收到频带共享参数之后，可以根据频带共享参数中的指示来使用共享频带资源。
本发明实施例提供了一种频带共享方法，通过第二网络设备向第一网络设备发送频带共享辅助信息，使得第一网络设备根据频带共享辅助信息对第二网络设备的频带共享参数进行配置，避免了第二网络设备之间在共享频带资源的过程中发生干扰，也同时可以避免第二网络设备与已占用该共享频带资源的现有无线通信系统之间的干扰。
参见图7A，为本发明实施例提供的一种频带共享方法的详细实施例，在本实施例中，该方法以图2所示的应用场景为例进行说明，其中，第一网络设备为宏基站1(200)或者中心控制单元(204)，第二网络设备为小小区X(205)所在的小基站LPN1，相应的，对于与宏基站1(200)不同的运营商而言，第一网络设备为宏基站2(202)或者中心控制单元(204)，第二网络设备为小小区Y(206)所在的小基站LPN2，本实施例以小小区X(205)所在的小基站LPN1作为第二网络设备，以宏基站1(200)或中心控制单元(204)为第一网络设备，以宏基站2(202)为第三网络设备为例进行说明，该方法包括：
S701a：LPN1获取自身的射频参数；
具体的，LPN1可以通过监听周围的LPN的射频参数来确定自身的射频参数，例如，LPN1可以选择没有被周围的LPN使用的频率；或者当LPN1所支持的频率均被周围的LPN使用时，则LPN1将选择一个频率，但该频率可以是被周围最少LPN使用的频率，也可以是被周围LPN使用但来自周围LPN的信号强度最小的频率等，然后LPN1在该频率上确定一个未被周围LPN使用的PCI，可以使得LPN1与周围共享使用频率的同系统的LPN之间干扰最小。
更加具体的，LPN1监听周围的LPN的方法可以是LPN1通过检测周 围LPN的同步信号，获知周围LPN所使用的频率和PCI。在LTE系统中，LPN1可以通过检测PSS和SSS获知周围LPN的频率和PCI，当然LPN1也可以检测其他物理层信号，比如发现信号等来获知周围LPN的频率和PCI信息。本实施例对此不作具体限定。
S702a：LPN1向第一网络设备发送射频参数；
示例性的，LPN1可以将射频参数(频率，还可以包括PCI)封装成频带共享辅助信息的形式向第一网络设备宏基站1(200)进行发送。
S703a：第一网络设备根据射频参数为LPN1配置频带共享参数；
示例性的，结合图2所示的场景，当第一网络设备为中心控制单元(204)的时候，中心控制单元可以根据前述实施例中通过图4对S302进行的详细描述对LPN1配置对应的频带共享参数，并且配置的频带共享参数已经是中心控制单元针对不同运营商的宏基站所部署的小小区的基站来进行配置，因此不会存在多个运营商之间的干扰问题；
但是当第一网络设备为宏基站1(200)的时候，宏基站1(200)仅能够根据前述实施例中通过图4对S302进行的详细描述对自身覆盖范围内所部署的LPN1配置对应的频带共享参数，因此，还需要考虑其他运营商的宏基站，如本实施例中的LPN2带来的干扰，因此，当第一网络设备为宏基站的时候，本方法还可以包括，S705a：接收第三网络设备宏基站2发送的频带共享协商信息；可以理解的，S705a这一步骤可以在S703a之前的任何时候进行，本发明实施例对该步骤的执行时刻不作具体的限定，如图7A中空心箭头所示。
需要说明的是，宏基站1(200)接收到宏基站2(202)发送的频带共享协商信息中可以包括不同类型的信息，并且结合这些不同类型的信息为LPN1配置频带共享参数，具体的配置过程如前述实施例所述，在此不再赘述。
S704a：第一网络设备向LPN1发送频带共享参数。
示例性的，LPN1在接收到频带共享参数之后，可以根据频带共享参数中的指示来使用共享频带资源。
参见图7B，为本发明实施例提供的另一种频带共享方法的详细实施例，在本实施例中，该方法以图2所示的应用场景为例进行说明，其中，第一网络设备为宏基站1(200)或者中心控制单元(204)，第二网络设备为小小区X(205)所在的小基站LPN1，相应的，对于与宏基站1(200)不同的运营商而言，第一网络设备为宏基站2(202)或者中心控制单元(204)，第二网络设备为小小区Y(206)所在的小基站LPN2，本实施例以小小区X(205)所在的小基站LPN1作为第二网络设备，以宏基站1(200)或中心控制单元(204)为第一网络设备，以宏基站2(202)为第三网络设备为例进行说明，该方法包括：
S701b：LPN1获取自身的位置参数；
具体的，LPN1可以通过相关的定位技术定位获得自身的位置参数，比如LPN1具备GPS功能、OTDOA，从而获知LPN1的位置参数；或者LPN1有后向连接的话，LPN1的位置参数即为后向连接的宽带连接信息，比如宽带接入点信息；或者当作为LPN1的LPN与Wi-Fi接入点集成到同一装置时，LPN1的位置参数即与该LPN1集成在同一装置中的Wi-Fi接入点的位置信息等，本发明实施例对此不再赘述。。
S702b：LPN1向第一网络设备发送位置参数；
示例性的，LPN1可以将位置参数封装成频带共享辅助信息的形式向第一网络设备宏基站1(200)进行发送。
S703b：第一网络设备根据位置参数为LPN1配置频带共享参数；
示例性的，结合图2所示的场景，当第一网络设备为中心控制单元(204)的时候，中心控制单元可以根据前述实施例中通过图4对S302进行的详细描述对LPN1配置对应的频带共享参数，并且配置的频带共享参数已经是中心控制单元针对不同运营商的宏基站所部署的小小区的基站来进行配置，因此不会存在多个运营商之间的干扰问题；
但是当第一网络设备为宏基站1(200)的时候，宏基站1(200)仅能够根据前述实施例中通过图4对S302进行的详细描述对自身覆盖范围内所部署的LPN1配置对应的频带共享参数，因此，还需要考虑其他运营商的宏基站，如本实施例中的LPN2带来的干扰，因此，当第一网络设备为宏基站的时候，本方法还可以包括，S705b：接收第三网络设备宏基站2发送的频带共享协商信息；可以理解的，S705b这一步骤可以在S703b之前的任何时候进行，本发明实施例对该步骤的执行时刻不作具体的限定，如图7B中空心箭头所示。
需要说明的是，宏基站1(200)接收到宏基站2(202)发送的频带共享协商信息中可以包括不同类型的信息，并且结合这些不同类型的信息为LPN1配置频带共享参数，具体的配置过程如前述实施例所述，在此不再赘述。
S704b：第一网络设备向LPN1发送频带共享参数。
示例性的，LPN1在接收到频带共享参数之后，可以根据频带共享参数中的指示来使用共享频带资源。
参见图8，为本发明实施例提供的一种第一网络设备80，具体可以是如图2所示的宏基站1(200)或者中心控制单元(204)，第一网络设备80可以包括：接收单元801、配置单元802以及发送单元803，其中，
接收单元801配置为，接收由至少一个第二网络设备发送的频带共享辅助信息；
配置单元802配置为，根据所述频带共享辅助信息为所述至少一个第二网络设备配置对应的频带共享参数；
发送单元803配置为，将所述频带共享参数对应的发送至所述至少一 个第二网络设备。
示例性的，频带共享辅助信息可以包括第二网络设备的射频参数，至少包括频率，优选的，还可以包括PCI；
或者，频带共享辅助信息可以包括第二网络设备的位置参数。
示例性的，频带共享参数用于所述第二网络设备根据所述频带共享参数使用共享频带资源；根据前述中的频带共享辅助信息具有不同类型的参数，因此，配置单元802也相应的可以通过不同的方法为所述至少一个第二网络设备配置对应的频带共享参数。
可选的，当所述频带共享辅助信息包括第二网络设备的射频参数，比如包括所述第二网络设备的频率，优选的，还包括所述第二网络设备的PCI的时候；配置单元802具体配置为，为所述频带共享辅助信息中的频率相同的第二网络设备配置相同的第一使用时间，所述第一使用时间为指示所述第二网络设备使用共享频带资源的使用时间。所述第二网络设备可以只在第一使用时间内进行开启或者只在第一使用时间内使用接收和发送信号，这样可以避免第二网络设备在不同时间连续占用该频率而导致其他使用该频率的异系统站点或设备一直无法使用该频率，从而避免对这些异系统站点或设备的正常通信产生干扰。
可选的，当所述频带共享辅助信息包括第二网络设备的位置参数的时候，配置单元802具体配置为，
根据所述频带共享辅助信息中的位置参数将所述至少一个第二网络设备进行分簇，分簇的原则可以是：同簇的第二网络设备具有相邻覆盖或者重叠覆盖。
对于分簇后的第二网络设备，配置单元802可以根据预先设定的配置规则从以下两种方式中任选一种方式为同簇的第二网络设备配置频带共享参数，具体如下所述：
方式一、配置单元802为同簇内的第二网络设备配置相同的频率，互不相同的PCI，以及相同的第二使用时间；
具体的，互不相同的PCI可以使得第二网络设备与其周围共享使用相同频率的其他第二网络设备之间的干扰最小，而所述第二使用时间为指示所述第二网络设备使用共享频带资源的时间。并且与第一使用时间类似的，为同簇的第二网络设备配置相同的频率以及相同的第二使用时间可以使得使用相同频率的同簇内的第二网络设备只在第二使用时间内进行开启或者只在第二使用时间内接收和发送信号，这样可以避免第二网络设备在不同时间连续占用该相同的频率而导致其他使用该频率的异系统站点或设备一直无法使用该频率道，从而避免对这些异系统站点或设备的正常通信产生干扰。
方式二、配置单元802为同簇内的第二网络设备配置互不相同的频率，以及为同簇内配置了互不相同的频率的第二网络设备配置第三使用时间；
具体的，为同簇内的第二网络设备配置互不相同的频率可以使得第二网络设备与相邻或相近的同簇其他第二网络设备之间的干扰达到最小，需要说明的是，不同簇之间配置的频率是可以相同的，这是因为不同簇之间物理位置相距较远，大大降低了散射在自由空间中的电磁波功率，所以即使为不同簇配置了同一个频率，也不会在两个簇之间产生干扰，而且针对不同簇使用相同的频率，可以更加有效地对有限的频率资源进行复用，从而提高了有限频率资源的使用效率；并且由于为同簇内的第二网络设备配置了互不相同的频率，因此所述各个第二网络设备的第三使用时间可以独立配置，而不会出现同簇内的第二网络设备在不同时间连续占用同一个频率而导致其他使用该频率的站点或设备一直无法使用该频率。
需要说明的是，当第二网络设备数量较多，多于可分配的频率时，配置单元802可以结合以上两种方式一起为第二网络设备配置频带共享参数。
结合图2所示的场景，上述的第一网络设备80具体为中心控制单元，如前述实施例中所述，由于中心控制单元负责对区域内多个运营商部署的小基站分配共享频带资源，因此，中心控制单元的配置单元802在如前所述的对第二网络设备配置对应的频带共享参数的过程中，已经解决了多个运营商部署的小小区之间的干扰问题；
但是，由于宏基站仅能接收本运营商所部署的第二网络设备发送的频带共享辅助信息，无法直接接收来自其他运营商所部署的第二网络设备发送的频带共享辅助信息，因此，当宏基站的配置单元802为第二网络设备配置对应的频带共享参数时，还需要考虑并解决与其他运营商所部属的第二网络设备之间的干扰，因此，当第一网络设备80为宏基站的时候，接收单元801还可以配置为，接收第三网络设备发送的频带共享协商信息；
可选的，频带共享协商信息可以包括所述第一网络设备80的运营商和第三网络设备的运营商通过协商确定互斥使用的频带或第三网络设备获取到的第四网络设备的频率以及第四使用时间；在本实施例中，第三网络设备可以是与第一网络设备80不同运营商的宏基站，而第四网络设备则是作为第三网络设备的宏基站所部署的小小区所在的小基站；
相应的，当频带共享协商信息为第一网络设备80的运营商和第三网络设备的运营商通过协商确定互斥使用的频带时，配置单元802还配置为，在所述第一网络设备80的运营商所确定使用的频带上，将所述频带共享辅助信息中的频率相同的第二网络设备配置相同的第一使用时间，所述第一使用时间为指示所述第二网络设备使用共享频带资源的使用时间；或者，
当频带共享协商信息为第三网络设备获取到的第四网络设备的频率以及第四使用时间时，配置单元802还配置为，当所述第四网络设备的频率与所述第二网络设备的频率相同时，将使用相同频率的第二网络设备的第一使用时间配置为所述第三网络设备获取到的所述使用相同频率的第四网络设备的第四使用时间。
可选的，频带共享协商信息可以包括第一网络设备80的运营商和第三网络设备的运营商通过协商确定互斥使用的频带或第三网络设备获取到的第四网络设备的位置信息、频率、PCI、以及第五使用时间；
相应的，当频带共享协商信息为第一网络设备80的运营商和第三网络设备的运营商通过协商确定互斥使用的频带时，配置单元802还配置为，在所述第一网络设备80的运营商所确定使用的频带上，根据所述频带共享辅助信息中的位置参数将所述至少一个第二网络设备进行分簇；并为同簇内的第二网络设备配置相同的频率，互不相同的小区物理标识PCI，以及相同的第二使用时间；或者。
当频带共享协商信息为第三网络设备获取到的第四网络设备的位置信息、频率、PCI、以及第五使用时间时，配置单元802还配置为：
根据所述第三网络设备获取到的第四网络设备的位置信息以及配置的频率确定所述第四网络设备处于任一簇所述第二网络设备的范围内且所述第四网络设备的频率与所述第一网络设备80为该簇第二网络设备配置的频率相同；
当所述第四网络设备处于任一簇所述第二网络设备的范围内且所述第四网络设备的频率与所述第一网络设备80为该簇第二网络设备配置的频率相同的时候，将该簇第二网络设备的PCI配置为与所述第四网络设备配置的PCI互不相同，并将该簇第二网络设备的第二使用时间配置为所述第四网络设备配置的频率所对应的第五使用时间。
可选的，频带共享协商信息可以包括第一网络设备80的运营商和第三网络设备的运营商通过协商确定互斥使用的频带或第三网络设备获取到的第四网络设备的位置信息和频率；
相应的，当频带共享协商信息为第一网络设备80的运营商和第三网络设备的运营商通过协商确定互斥使用的频带时，配置单元802还配置为，在所述第一网络设备80的运营商所确定使用的频带上，根据所述频带共享辅助信息中的位置参数将所述至少一个第二网络设备进行分簇；并为同簇内的第二网络设备配置互不相同的频率，以及为所述同簇内配置了互不相同的频率的第二网络设备配置第三使用时间；或者
当频带共享协商信息为第三网络设备获取到的第四网络设备的位置信息和频率时，配置单元802还配置为：
根据所述第三网络设备获取到的第四网络设备的位置信息确定所述第四网络设备处于任一簇所述第二网络设备的范围内；当所述第四网络设备处于任一簇所述第二网络设备的范围内的时候，根据所述第四网络设备的频率将该簇第二网络设备的频率配置为所述第四网络设备没有配置的频率。
需要说明的是，以上描述中的第一使用时间、第二使用时间、第三使用时间、第四使用时间和第五使用时间的具体形式可以为：周期性分配的 一段连续时间，如图5A所示，以第一使用时间为例，第一使用时间以周期500a周期性出现，占用一个周期中所示的一段连续时间501a，如图5A中的阴影部分所示。第一网络设备或中心控制单元可以配置周期500a、第一使用时间时长501a以及第一使用时间起始时间502a等参数，以用于第二网络设备确定第一使用时间；
或者可以是单次分配使用的一段连续时间，同样以第一使用时间为例，第一网络设备或中心控制单元可以配置第一使用时间时长、第一使用时间起始时间等参数，以用于第二网络设备确定第一使用时间；
或者可以是周期性分配的离散时间，如图5B所示，以第一使用时间为例，第一使用时间以周期500b周期性出现，占用一个周期500b中所示的各段离散时间501b，如图5B中的阴影部分所示。第一网络设备或中心控制单元需要配置周期500b、第一使用时间起始时间502b、各段离散时间501b在周期内的位置等参数，以用于第二网络设备确定第一使用时间。
还需要说明的是，配置单元802还可以从用户设备或者第二网络设备侧获取的同频段上在用系统(比如WLAN)的负荷、频率使用情况等信息为第二网络设备配置频带共享参数。
在实际应用中，所述接收单元801、配置单元802以及发送单元803均可由中央处理单元(CPU，Central Processing Unit)、或数字信号处理(DSP，Digital Signal Processor)、或微处理器(MPU，Micro Processor Unit)、或现场可编程门阵列(FPGA，Field Programmable Gate Array)等来实现；所述CPU、DSP、MPU、FPGA均可内置于宏基站或者中心控制单元中。
本发明实施例提供了一种第一网络设备80，通过第一网络设备80的配置单元802根据第二网络设备发送的频带共享辅助信息对第二网络设备的频带共享参数进行配置，避免了第二网络设备之间在共享频带资源的过程中发生干扰，也同时可以避免第二网络设备与已占用该共享频带资源的现有无线通信系统之间的干扰。

接收单元903配置为接收由第一网络设备发送的频带共享参数。
可选的，频带共享辅助信息可以包括第二网络设备90的射频参数，比如第二网络设备90的频率，优选的，还可以包括第二网络设备90的小区物理标识PCI；
具体的，获取单元901可以通过监听周围的第二网络设备的射频参数来确定自身的射频参数，例如，获取单元901可以选择没有被周围网络设备使用的频率；或者当第二网络设备90所支持的频率均被周围的第二网络设备使用时，则获取单元901将选择一个频率，但该频率可以是被周围最 少网络设备使用的频率，也可以是被周围网络设备使用但来自周围网络设备的信号强度最小的频率等，然后获取单元901在该频率上确定一个未被周围的第二网络设备使用的PCI，可以使得第二网络设备90与周围共享使用频率的同系统的第二网络设备之间干扰最小。
更加具体的，获取单元901监听周围的第二网络设备的方法可以是获取单元901通过检测周围第二网络设备的同步信号，获知周围第二网络设备所使用的频率和PCI。在LTE系统中，获取单元901可以通过检测PSS和SSS获知周围第二网络设备的频率和PCI，当然获取单元901也可以检测其他物理层信号，比如发现信号等来获知周围第二网络设备的频率和PCI信息。本发明实施例对此不做具体限定。
可选的，频带共享辅助信息可以包括第二网络设备90的位置参数；
具体的，第二网络设备90的位置参数可以由获取单元901通过相关的定位技术定位获得，比如第二网络设备90具备GPS功能、OTDOA，从而获取单元901获知第二基站的位置参数；或者第二网络设备90有后向连接的话，第二网络设备90的位置参数即为后向连接的宽带连接信息，比如宽带接入点信息；或者当作为第二网络设备90的LPN与Wi-Fi接入点集成到同一装置时，第二网络设备90的位置参数即与该第二网络设备90集成在同一装置中的Wi-Fi接入点的位置信息等，本发明实施例对此不再赘述
此外，频带共享辅助信息也可以包括第二网络设备90的位置参数和射频参数，本发明实施例对此不再赘述。
示例性的，频带共享辅助信息可以用于第一网络设备根据所述频带共享辅助信息来为所述第二网络设备90配置相应的频带共享参数，具体的配置过程如前述实施例中所述，在此不再赘述。
而频带共享参数是用于指示所述第二网络设备90使用共享频带资源，从而避免所述第二网络设备90与其他第二网络设备之间在使用共享频带资源过程中发生干扰，也同时可以避免第二网络设备90与已占用该共享频带资源的现有无线通信系统之间的干扰。
示例性的，第二网络设备90在接收单元903接收到频带共享参数之后，可以根据频带共享参数中的指示来使用共享频带资源。
在实际应用中，所述获取单元901、发送单元902和接收单元903均可由中央处理单元(CPU，Central Processing Unit)、或数字信号处理(DSP，Digital Signal Processor)、或微处理器(MPU，Micro Processor Unit)、或现场可编程门阵列(FPGA，Field Programmable Gate Array)等来实现；所述CPU、DSP、MPU、FPGA均可内置于网络设备中。
