Abstract
本发明公开了一种中继站点识别宿主站的方法、装置、系统和存储介质,所述方法包括:中继站点在空闲状态下接收固定基站下发的携带有该固定基站是否支持中继功能的广播消息;中继站点接入到支持中继能力的固定基站i,并接收固定基站i发送的专用消息,获取与固定基站i邻接的固定基站是否支持中继功能的信息;中继站点在移动过程中,对移动到的支持中继功能的邻接固定基站进行用于小区切换的测量操作。
Description
本发明涉及通信技术领域,尤其涉及一种中继站点识别宿主站的方法、装置、系统和存储介质。
蜂窝无线通信系统主要由用户终端(UE,User Equipment)、接入网和核心网(CN,Core Network)组成。基站、或基站和基站控制器组成的网络称为无线接入网(RAN,Radio Access Network),RAN负责接入层事务,例如无线资源的管理。基站之间可以存在物理或者逻辑上的连接。
蜂窝无线通信系统中,目前的固定基站网络的无线覆盖通常由于各种原因受到限制,例如:建筑结构对无线信号的阻挡等原因造成的无线网络覆盖漏洞。另外,在小区的边缘地区,由于无线信号强度的减弱,以及相邻小区的干扰,导致UE在小区边缘时,通信质量较差,无线传输的错误率抬高。为了提高数据传输吞吐量、群组移动性、临时网络部署、小区边缘地区的吞吐量以及新区域的覆盖,目前一种解决方案是在蜂窝无线通信系统中引入一种无线网络节点,称为中继(Relay)。
Relay是通过无线链路来中继数据的站点,也称中继节点/中继站(Relay Node/Relay Station),下文将其统称为RN站点,其工作原理如图1所示。RN站点通过无线方式连接到宏小区并进一步连入无线接入网,以DeNB(Donor eNodeB)的角度来讲,RN是一个UE,RN对于其所覆盖的UE看来,是一个eNodeB。
目前的Relay按种类分有3类:固定Relay、游牧Relay、移动Relay。固定Relay和游牧Relay都是定点部署的,区别在于游牧Relay可以即插即
用,部署起来比固定Relay方便。移动Relay自身具有一定的移动性,典型的应用场景是在火车或汽车等交通工具上部署移动Relay,以方便为交通工具里的UE提供较好的服务。在移动切换上,移动Relay作为一个汇聚网元,将大量UE的同时移动,汇聚成移动Relay—个网元的移动,这样可以减少切换时的信令在空口和网络中的开销。
由于移动Relay所处的网络环境的多样化,RN站点所处的网络环境中,必然同时存在大量的支持RN站点的固定基站和不支持RN的固定基站并存的场景。目前的实现,固定基站没有手段可以告知RN站点是否支持Relay,导致RN站点在移动过程中,重选或切换到不支持Relay的固定基站,造成不必要的失败的接入尝试。

步骤S301,各固定基站下发携带有自身是否支持中继功能的广播消息;
步骤S302,某支持中继功能的固定基站i,基于中继站点请求,将所述中继站点接入;
步骤S303,固定基站i将预先获取的与本固定基站i邻接的固定基站是否支持中继功能的信息、通过专用消息发送至所述中继站点,以使中继站点只对移动到的支持中继功能的邻接固定基站进行测量。
其中,固定基站i获取与本固定基站i邻接的固定基站是否支持中继功能信息的方式包括但不限于为:
固定基站i与邻接的固定基站存在X2接口时,固定基站i与邻接的固定基站间在X2接口建立流程中交互彼此的中继支持能力信息;
固定基站i与邻接的固定基站不存在X2接口时,固定基站i与邻接的固定基站间通过移动管理实体MME交互彼此的中继支持能力信息。
在一个实施例中,当邻接的固定基站的中继支持能力变化时,若存在X2接口,则该邻接的固定基站发起X2接口更新消息,将中继支持能力变化信息通知给固定基站i;若不存在X2接口,则将中继支持能力变化信息通过MME通知给固定基站i。
综上所述,可知本发明实施例提出了一种固定基站通过广播和专用信令提前告知RN站点当前固定基站、邻接固定基站是否支持Relay的处理方法,通过使用该方法,可以避免RN站点在不支持Relay的固定基站发起无用接入,提高RN站点移动过程重选和切换的成功率和有效性。
基于实施例二,本发明实施例还提供了一种存储介质,该存储介质包括一组指令,当执行所述指令时,引起至少一个处理器执行上文所述的操
作。
为了更清楚的阐述本发明,下面根据图4~图5给出本发明一个较佳的实施例,并结合对实施例的描述,进一步给出本发明的技术细节,使其能够更好地说明本发明提供的方法的具体实现过程。需要说明的是,如下所涉及的固定基站同时也指代固定小区。
本发明实施例提出的中继站点识别宿主站点的方案分为空闲态和连接态两种场景。
对于空闲态下的具体处理流程如图4所示,包括:
步骤1,固定基站侧空口下发广播消息,广播消息中根据固定基站自身能力,携带固定基站是否支持Relay信元;
步骤2,RN站点读取固定基站侧广播,如果固定基站侧指示支持Relay功能,RN站点根据自身需求发起接入,流程结束,否则转步骤3;
步骤3,RN站点重选到其他支持Relay功能的固定基站。
对于连接态下的具体处理流程如图5所示,包括:
步骤1,固定基站1获取与其邻接的固定基站2的Relay支持能力。
步骤2,RN站点同步到固定基站1,在该基站发起RRC连接建立,如果固定基站2不支持Relay,转步骤6,否则转步骤3。
步骤3,固定基站1向RN站点发送RRC连接重配消息,指示RN不必将固定基站2加入黑小区列表。
步骤4,RN站点向固定基站2移动,检测到固定基站2信号质量满足切换门限,上报测量结果给固定基站1。
步骤5,固定基站1决策满足切换条件,支持RN站点切换至固定基站2,流程结束。
步骤6,固定基站1向RN站点发送RRC连接重配消息,指示RN将固定基站2加入黑小区列表,RN站点不再测量固定基站2,流程结束。
为了更好的阐述本发明,下面给出几个具体示例,以更好的说明连接态下的处理流程。
示例一:固定基站1与邻接的固定基站2存在X2接口,固定基站1支持Relay,固定基站2支持Relay,具体的流程如下,包括以下步骤:
步骤1,在X2接口建立流程中,固定基站1向固定基站2发起X2建立请求,请求消息中告知固定基站2自身支持Relay功能。
步骤2,固定基站2向固定基站1回复X2建立响应,通知固定基站1自身支持Relay功能。
步骤3,RN站点在固定基站1发起RRC接入,固定基站1在专用消息即RRC连接重配消息中指示不必将固定基站2加入黑小区列表。
步骤4,RN站点向固定基站2移动,检测到固定基站2信号质量满足切换门限,上报测量报告给固定基站1,列表中包含固定基站2。
步骤5,固定基站1与固定基站2完成切换准备工作,固定基站1下发切换命令给RN站点,通知RN站点向固定基站2切换。
步骤6,RN站点成功同步到固定基站2,完成切换,流程结束。
示例二:固定基站1与邻接的固定基站2存在X2接口,固定基站1支持Relay,固定基站2不支持Relay,具体的流程包括以下步骤:
步骤1,在X2接口建立流程中,固定基站1向固定基站2发起X2建立请求,请求消息中告知固定基站2自身支持Relay功能。
步骤2,固定基站2向固定基站1回复X2建立响应,通知固定基站1自身不支持Relay功能。
步骤3,RN站点在固定基站1发起RRC接入,固定基站1在专用消息即RRC连接重配消息中指示将固定基站2加入黑小区列表。
步骤4,RN站点移动过程中不再检测固定基站2,而选择其他支持Relay的站点进行测量,流程结束。
示例三:固定基站1和邻接的固定基站2存在X2接口,当基站的Relay支持能力发生变化时的具体流程如下:
步骤1,在X2接口建立流程中,固定基站1向固定基站2发起X2建立请求,请求消息中告知固定基站2自身支持Relay功能。
步骤2,固定基站2向固定基站1回复X2建立响应,通知固定基站1自身不支持Relay功能。
步骤3,固定基站2的Relay支持能力发生变化,从不支持变为支持,固定基站2向固定基站1发起X2更新消息,通知固定基站1自身支持Relay功能。
步骤4,固定基站1回复更新确认消息给固定基站2,指示收到更新消息。
示例四:固定基站1和固定基站2不存在X2接口,只存在S1接口,固定基站之间Relay支持能力可通过MME交互,具体流程如下:
步骤1,固定基站1将自身Relay支持能力发送给MME。
步骤2,MME将固定基站1的Relay支持能力发送给固定基站2,固定基站2保存固定基站1的Relay支持能力。
步骤3,固定基站2收到MME通知的固定基站1的Relay支持能力后,如果未向对端发送过自身能力,将自身的Relay支持能力发给MME。
步骤4,MME收到固定基站2的Relay支持能力后,将固定基站2的Relay支持能力发送给固定基站1,固定基站1保存固定基站2的Relay支持能力。
经过上述阐述可知,中继站点在小区选择/重选过程的场景(即中继站点为空闲态),固定基站在广播信息中增加信元,以标志固定基站是否支持Relay功能,即固定基站是否是Donor站点(宿主站点)。RN站点在小区选择过程中,通过读取固定基站广播中的“是否支持Relay”信元判断该固定基
站是否具有Donor基站功能,如果支持,可以在当前固定基站发起RRC连接请求继而在该固定基站开始业务。如果该固定站点不具有Donor基站功能,RN站点则继续选择其他站点同步。
中继站点在连接态移动性场景,X2\S1交互消息中增加标识Relay功能,配置为标识是否存在及是否支持Relay信元,固定基站通过S1/X2接口获取邻接固定基站的Relay支持信息,并通过专用消息告知RN站点,邻接站点如果不支持Relay功能,RN站点可以对邻接站点不进行测量,避免后续发生不必要错误切换。

本实施例中,专用消息可以但不限于为无线资源控制协议RRC连接重配消息。
综上所述,可知本发明实施例提出了一种固定基站通过广播和专用信
