Description
服务节点的选择方法及设备 本申请要求于 2009 年 3 月 16 日提交中国专利局、 申请号为 200910118792. 发明名称为 "服务节点的选择方法及设备" 的中国专利 申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及通信技术领域, 特别涉及服务节点的选择方法及设备。 背景技术 第三代合作伙伴计划( 3GPP )近期在即将完成的长期演进( Long Term Evolution, LTE ) 系统下启动了 LTE的增强演进版本——高级的长期演进 ( LTE- Advanced ) , 以满足国际电信联盟 ( ITU ) 规定的技术指标。 LTE-Advance中引入了中继站(Relay Node, RN ), 用来实现高速率的无线 网络覆盖、 提高小区边 吐率、 提供新的区域覆盖等功能。
中继站通过一条无线链路和基站(eNB )相连, 如图 la所示, 如果终端 ( User Equipment, UE )在中继站的覆盖范围 (图中虚线所示), 则可以先 和中继站相连, 然后中继站和基站相连, 从而实现该终端的空中连接。
现有 LTE技术中, 空闲状态的终端在选择服务节点时,是根据接收到服 务节点发送的信号的信号质量来选择的, 而信号质量一般用参考符号接收 功率(RSRP )、 信噪比(SNR )、 信干噪比(SINR )等参数来表示, 终端根 据接收的信号的信号质量的好坏对所处小区的服务节点进行排序, 并选择 发送信号质量较好( RSRP或 SINR较大) 的服务节点作为当前的服务节点; 而对于处于连接状态的终端, 在当前服务小区信号质量降低、 相邻小区质 量高于某服务小区、 相邻小区质量高于某个阔值等情况发生时, 终端会将 该情况以测量报告的形式上报给服务节点, 服务节点会根据切换判决方法 进行切换判决, 并和相邻小区协商后确定是否切换该终端。
由于中继站的引入, 使得终端会出现如图 lb所示的情况, 即终端处于 中继站和基站共同覆盖范围内。 在终端接收到的中继站的功率较大的情况 下, 终端会按照现有小区选择 /重选准则驻留在中继站下, 则终端先连接到
中继站, 再由中继站连接到基站。 由于受基站到中继站链路的影响, 终端 选择驻留在中继站下会消耗较多的资源。
发明内容 本发明实施例提供服务节点的选择方法及相关设备, 使得终端能以节 省资源消耗的目的来选择服务节点。

本发明提供的一种网络侧设备, 包括:
确定单元, 用于确定从基站到终端的链路损失是否小于与所述基站和 所述终端所在小区的中继站相关的链路损失;

本发明提供的一种终端, 包括:
获得单元, 用于获得与从基站到终端的链路损失, 及从所述基站到中 继站的链路损失, 或与从所述基站通过中继站到所述终端的链路损失相关 的数据;

所述终端所在小区的中继站相关的链路损失;
选择单元, 用于如果所述确定单元确定的结果为小于时, 选择所述基 站为所述终端的服务节点。
本发明的服务节点的选择方法是当终端处于连接状态时, 当网络侧判 断确定从基站到终端链路损失小于与基站和中继站相关的链路损失, 即从 基站到中继站链路损失或从所述基站通过中继站到所述终端的链路损失 时, 判决终端切换到基站; 当终端处于空闲状态时, 当终端确定从基站到 终端链路损失小于与基站和中继站相关的链路损失, 即从基站到中继站链 路损失或从所述基站通过中继站到所述终端的链路损失时, 选择基站为服 务节点。 和现有技术中终端根据接收网络侧的信号的接收功率来选择服务 节点相比, 终端可以选择到终端的链路较优的网络侧设备作为服务节点, 节省了资源的消耗。
附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对 实施例或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的一些实施例, 对于本领域普通技术人员 来讲, 在不付出创造性劳动性的前提下, 还可以根据这些附图获得其他的 附图。

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, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没 有做出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的 范围。 方法实施例、
一种服务节点的选择方法, 本实施例中是处在连接状态的终端在选择 服务节点时的方法, 流程图如图 2所示, 包括:
步骤 101、 网络侧确定从基站到终端的链路损失是否小于与基站和该终 端所在小区的中继站相关的链路损失, 如果小于, 执行步骤 102; 当然, 如 果不小于, 则网络侧可以按照其他的判决规则对终端选择服务节点进行判 决。
可以理解, 这里与基站和该终端所在小区的中继站相关的链路损失为: 从基站到该终端所在小区的中继站的链路损失, 或从基站通过中继站到终 端的链路损失, 还可以是其他的链路损失, 并不限制本发明, 以下以前两 种链路损失为例说明。
步骤 102、 网络侧判决所述终端选择所述基站为服务节点, 并切换到所 述基站。
可以理解, 网络侧在执行步骤 101时, 可以根据终端上报的测量报告中 携带的链路损失信息进行判断, 也可以计算得到从基站到终端的链路损失 及基站到中继站的链路损失, 或计算从中继站到所述终端的路损, 或计算 得到从基站通过中继站到终端的链路损失来进行确定。
这里从基站到终端或中继站的链路损失可以通过计算基站发射信号的 信号质量与中继站 /终端接收所述基站信号的信号质量的差值得到。 而基站 通过中继站到所述终端的链路损失为: 基站发射信号的信号质量与中继站 接收所述基站信号的信号质量的差值, 与中继站发射信号的信号质量与终 端接收所述中继站信号的信号质量的差值之和。
其中信号质量可以用 RSRP、 SNR、 SINR等参数来表示,其中当用 RSRP 来表示时, 基站到中继站或终端的链路损失为: 基站的发射功率与中继站 或终端接收所述基站信号的接收功率的差值, 且 RSRP小的信号质量较差, 也就是说,对于用 RSRP来表示信号质量的情况来说, RSRP小表示信号质量 较差; 当用 SNR或 SINR来表示时, 基站到中继站或终端的链路损失为: 基 站发射信号的信噪比或信干噪比, 与中继站或终端接收所述基站信号的信 噪比或信干噪比的差值, 且 SNR或 SINR大的信号质量较好, 也就是说, 对 于用 SNR或 SINR来表示信号质量的情况来说, SNR或 SINR大的信号质量较 好;
上述网络侧为基站或中继站或单独的网络节点时, 流程相似, 以下以 其中一个为例来说明:
一个实施例、 本实施例中网络侧根据终端上报的测量报告判断, 流程 图如图 3所示, 服务节点的选择方法包括:
步骤 10、 终端获得与从基站到终端的链路损失, 及从该基站到该终端 所在小区的中继站的链路损失相关的数据, 或者与从该基站通过中继站到 该终端的链路损失相关的数据。
上述步骤 10提到的从该基站通过中继站到该终端的链路损失相关的数 据, 是指另一种方式, 即终端获得与从基站到终端的链路损失及从该基站 通过中继站到该终端的链路损失相关的数据。
上述从所述基站到所述终端所在小区的中继站链路损失或从所述基站 通过中继站到所述终端的链路损失等, 可以称为与所述基站和所述终端所 在小区的中继站相关的链路损失。
具体来说, 终端获得与从基站到终端的链路损失, 及从所述基站到该 终端所在小区的中继站的链路损失相关的数据, 或与从所述基站通过中继 站到所述终端的链路损失相关的数据是指: 计算上述链路损失所需要的数 据, 或上述链路损失的数值等。
终端可以才 据预置的测量信息进行测量, 预置的测量信息包括: 测量 周期参数, 待测量数据, 比如基站发送信号的信号质量, 其中的信号质量 具体可以是发射功率、 发射信号的信噪比等, 以及中继站发送信号的信号 质量等。 例如, 终端可以在测量周期进行上述测量; 终端还可以在一定的 条件下触发测量的步骤, 如终端接收中继站信号的信号质量比预置的信号 质量差等。
对于基站到中继站的链路损失, 终端在进行测量时, 可以直接通过专 用信令或广播接收来自中继站或基站的, 所述基站到中继站的链路损失; 也可以接收来自网络侧的, 中继站接收到基站信号的信号质量, 从基站或 中继站的广播中测量到基站发射信号的信号质量, 并在测量后计算基站发 射信号的信号质量与中继站接收基站信号的信号质量的差值, 得到基站到 中继站链路损失; 终端还可以从其他途径进行测量, 这些并不构成对本发 明的限制。 同样的方法可以得到与从该基站通过中继站到该终端的链路损 失。
步骤 11、 终端上报测量报告给网络侧;
测量报告中可以包括基站到终端链路损失和基站到中继站链路损失的 差值;
或从基站到终端的链路损失, 与从基站通过中继站到所述终端的链路 损失, 即与从所述基站到所述终端所在小区的中继站的链路损失, 及从所 述中继站到终端的链 i¾员失之和, 的差值;
或中继站接收到基站信号的信号质量,
或终端接收到基站信号的信号质量,
或指示从所述基站到终端链路损失小于从所述基站到中继站链路损失 的指示信息, 如一个空的 4艮告消息,
或指示从基站到终端的链路损失小于从所述基站到所述终端所在小区 的中继站的链路损失及从所述中继站到终端的链路损失之和的信息等。
可以理解, 终端在上报测量报告时, 是直接发送给当前的服务节点, 也可以在从基站到终端的链路损失小于从基站到中继站的链路损失时发送 给当前的服务节点。
步骤 12、 网络侧接收所述终端上报的测量报告;
这里的网络侧可以是终端当前的服务节点如中继站或基站, 也可以是
其他的服务节点, 这种情况下, 接收的终端的测量报告是由所述终端当前 的服务节点转发的。
步骤 13、 网络侧根据测量报告确定从基站到终端的链路损失是否小于 从基站到中继站的链路损失, 或小于从基站通过中继站到终端的链路损失, 如果小于, 执行步骤 14。
当然, 如果不小于, 网络侧则可以按照其他的判决规则对终端选择服 务节点进行判决;
如果测量报告中包含基站到终端链路损失和所述基站到中继站链路损 失的差值, 或包含从基站到终端的链路损失与从基站通过中继站到所述终 端的链路损失的差值, 则在该差值为负时确定为小于, 其中的从基站通过 中继站到所述终端的链路损失, 即为与从所述基站到所述终端所在小区的 中继站的链路损失及从所述中继站到终端的链路损失之和;
如果包含指示从所述基站到终端链路损失小于从所述基站到中继站链 路损失的指示信息, 或指示从基站到终端的链路损失小于从所述基站到所 述终端所在小区的中继站的链路损失及从所述中继站到终端的链路损失之 和的信息, 则直接确定为小于;
如果测量报告中包含中继站接收到终端信号的信号质量信息, 则网络 侧需要先获得基站发射信号的信号质量及终端接收基站信号的信号质量来 计算链路损失, 然后进行确定。
步骤 14、 网络侧判决所述终端选择所述基站为服务节点, 并切换到所 述基站。
另一个实施例、 本实施例中网络侧根据终端上报的测量报告判断, 本 实施例中的方法和实施例一中方法的区别在于, 本实施例中终端的测量信 息需要网络来配置, 而实施例一中终端的测量是根据预置的测量信息进行 测量的, 流程图如图 4所示, 服务节点的选择方法包括:
步骤 21、 网络侧配置终端测量事件;
终端测量事件可以包括: 从基站到终端链路损失是否小于从所述基站 到中继站链路损失, 或小于从所述基站通过中继站到所述终端的链路损失; 终端测量事件还可以包括测量周期, 上报测量报告的周期等。 待测量 数据, 比如基站发送信号的信号质量, 其中的信号质量具体可以是发射功 率、 发射信号的信噪比等, 以及中继站发送信号的信号质量等。
步骤 22、 将终端测量事件通过广播或专用信令发送给所述终端, 命令 终端根据终端测量事件上报测量报告;
这里的网络侧可以是指终端当前的服务节点, 在配置终端测量事件时, 网络侧可以在负载较重时, 配置终端测量事件, 命令终端进行测量; 也可 以在中继站接收基站信号的信号质量小于预置的信号质量时, 命令终端进 行测量, 这种情况下, 网络侧需要在步骤 21之前将所述中继站接收所述基 站信号的信号质量与预置的信号质量进行比较, 当所述中继站接收所述基 站信号的信号质量比预置的信号质量差时, 执行步骤 21。
步骤 23、 终端测量与从基站到终端链路损失及从所述基站到中继站链 路损失相关的数据, 或与从所述基站通过中继站到所述终端的链路损失相 关的数据;
上述步骤 23提到的与从该基站通过中继站到该终端的链路损失相关的 数据, 是指另一种方式, 即终端测量与从基站到终端的链路损失及从该基 站通过中继站到该终端的链路损失相关的数据。
本实施例中终端进行测量是根据网络侧配置的终端测量事件进行测 量。
步骤 24、 终端上报测量报告给网络侧进行服务节点的选择切换的判决; 测量报告中包括基站到终端链路损失和基站到中继站链路损失的差 值, 或终端接收到基站的信号的接收功率, 或指示从基站到终端链路损失 小于从基站到中继站链路损失的指示信息等, 和实施例一中所述相同, 在 此不再赘述。
可以理解, 终端在上^艮测量 告时, 可以在从基站到终端链路损失小 于从基站到中继站链路损失时进行上报, 也可以在测量后直接上报。
步骤 25、 网络侧接收到测量报告, 根据测量报告确定从基站到终端链 路损失是否小于从所述基站到中继站链路损失或从所述基站通过中继站到 所述终端的链路损失, 如果小于, 执行步骤 26;
如果不小于, 网络侧则可以按照其他的判决规则对终端选择服务节点 进行判决。
网络进行判断的过程如上述实施例一所示, 再次不再赘述。
步骤 26、 网络侧判决终端选择基站为服务节点, 并切换到所述基站。 实施例三、 本实施例中网络侧直接根据自己获得的信息进行判断, 流
程图如图 5, 服务节点的选择方法包括:
步骤 30、 网络侧获得基站发射信号的信号质量、 终端接收基站信号的 信号质量及中继站接收基站信号的信号质量;
步骤 31、 网络侧计算基站发射信号的信号质量与终端接收基站信号的 信号质量的差值得到从基站到终端的链路损失, 计算基站发射信号的信号 质量与中继站接收所述基站信号的信号质量信息得到从基站到中继站的链 «员失;
这里网络侧为终端当前的服务节点; 或终端当前所在小区的其他服务 节点, 这种情况下, 获得上述信息时可以接收终端当前的服务节点转发的 信息, 本实施例中从基站到终端链路损失和从基站到中继站链路损失都是 通过网络侧来计算。
步骤 32、 网络侧将从基站到终端链路损失与从基站到中继站链路损失 进行比较, 如果从基站到终端链路损失小于从基站到中继站链路损失, 则 执行步骤 33;
当然, 如果不小于, 则网络侧可以按照其他的判决规则对终端选择服 务节点进行判决。
步骤 33、 网络侧判决终端选择基站为服务节点, 并切换到基站。
实施例四、 本实施例中网络侧直接根据自己获得的信息进行确定的, 本实施例中的方法和实施例三中方法的区别在于, 本实施例中从所述基站 到中继站的链路损失直接从其他节点获取的, 不需要进行计算, 流程图如 图 6, 服务节点的选择方法包括:
步骤 40、 网络侧获得基站发射信号的信号质量、 终端接收所述基站信 号的信号质量及从基站到中继站的链路损失;
步骤 41、 网络侧计算基站发射信号的信号质量与终端接收所述基站信 号的信号质量的差值得到从基站到终端的链路损失;
步骤 42、 网络侧将从基站到终端链路损失与从基站到中继站链路损失 进行比较。
这里网络侧为终端当前的服务节点, 或终端当前所在小区的其他服务 节点。 本实施例中从基站到终端链路损失是通过网络侧来计算, 而从基站 到中继站链路损失是接收的终端或所述中继站发送的。 可以理解, 中继站 通过计算基站发射信号的信号质量与中继站接收所述基站信号的信号质量
的差值来获得基站到中继站链路损失, 之后, 中继站可以直接发送给所述 网络侧, 或发送给终端, 再由终端发送给所述网络侧。
步骤 43、 网络侧将从基站到终端链路损失与从基站到中继站链路损失 进行比较, 如果从基站到终端链路损失小于从基站到中继站链路损失, 则 执行步骤 44;
如果不小于, 网络侧可以按照其他的判决规则对终端选择服务节点进 行判决。
步骤 44、 网络侧判决终端选择基站为服务节点, 并切换到基站。
可以理解, 在其他实施例中, 网络侧还可以直接从其他节点获得从基 站到终端的链路损失, 而计算从所述基站到中继站的链路损失来进行判断。
在其他的实施例中, 若与基站和终端所在小区的中继站相关的链路损 失是从基站通过中继站到终端的链路损失, 则网络侧可以通过获得基站发 射信号的信号质量与中继站接收所述基站信号的信号质量的差值, 与中继 站发射信号的信号质量与终端接收所述中继站信号的信号质量的差值之 和, 并与获得的从基站到终端的链路损失进行比较来确定。 方法与上述实 施例相同, 在此不再赘述。
本发明实施例的服务节点的选择方法是当终端处于连接状态时, 当网 络侧确定从基站到终端链路损失小于与基站和中继站相关的链路损失, 即 从基站到中继站链路损失或从所述基站通过中继站到所述终端的链路损失 时等, 判决终端切换到基站, 和现有技术中终端根据接收网络侧的信号的 信号质量来选择服务节点相比, 使得终端可以选择到终端的链路较优的网 络侧设备作为服务节点, 减少了以后通信的链路损失, 节省了资源的消耗。 方法实施例、

这里与所述基站和所述终端所在小区的中继站相关的链路损失是指: 从基站到中继站链路损失或从基站通过中继站到终端的链路损失等。
终端在执行步骤 201时, 需要先获得从基站到终端链路损失和从基站到 中继站链路损失, 再将获得两个链路损失进行比较来确定; 或获得基站发 射信号的信号质量与中继站接收所述基站信号的信号质量的差值, 与中继 站发射信号的信号质量与终端接收所述中继站信号的信号质量的差值之 和, 并与获得的从基站到终端的链路损失进行比较来确定。 可以理解, 终 端可以通过广播或专用信令直接接收网络侧发送的链路损失; 也可以获得 基站发射信号的信号质量、 中继站接收基站信号的信号质量, 自己计算链 路损失; 还可以通过其他的方法来获得, 并不构成对本发明的限制。
步骤 202、 终端选择所述基站为所述终端的服务节点。
