Description

信息配置装置、 通信装置和通信系统 技术领域
本发明涉及通信领域, 特别涉及一种信息处理装置、 通信装置和通信系统。 背景技术
目前, 在长期演进 (LTE, Long Term Evolution) 系统中, 设备和设备间的通信 (D2D通信) 需要通过无线接入网和核心网来完成。 随着新的业务需求的出现, 同时 为了减少网络的负载, 实现网络负载的转移, 设备和设备间的通信逐渐成为一个新的 研究方向。 当两个终端之间的距离足够近时, 该终端可以互相发现对方的存在, 从而 可以在基站的控制下进行设备与设备间的直接通信。
为了实现设备与设备间的通信, 在增强的 LTE (LTE-Advanced) 系统中定义了两 种空口设备与设备间通信的资源分配方式, 即模式 l (Mode 1)和模式 2 (Mode 2)。
模式 1 是指基站调度的资源分配方式。 其特点是: 为了传输数据, 终端需要在 RRC 连接 (RRC— CONNECTED) 状态下; 终端向基站请求传输资源; 基站调度资源给终 端来传输调度分配和数据;
为了请求传输资源, 终端发送调度请求和缓存状态报告给基站; 该基站基于该缓 存状态报告, 可以确定该终端有设备到设备间的通信数据发送以及要发送的数据量。
模式 2是指终端自己选择资源的资源分配方式。其特点是: 基站配置一个资源池 给终端; 当有设备到设备间的数据需要发送时, 该终端自己从资源池中选择资源来送 调度分配和数据;
目前, 终端采用上述哪种资源分配方式来通信是根据基站的配置来决定的, 即如 果基站配置的是模式 1, 则该终端就采用模式 1的机制来进行设备到设备间的通信; 如果基站配置的是模式 2,则该终端就采用模式 2的机制来进行设备到设备间的通信。
设备到设备间的通信的一个重要应用是公共安全 (Public safety) , 而公共安全 的一个基本的需求是需要保证业务的连续性, 即尽量减少业务通信过程中出现的中 断。
应该注意, 上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、 完整的说明, 并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发 明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。 发明内容
在终端严格按照基站配置的资源分配方式来进行设备到设备间的通信时,在某些 情况下会出现业务中断。例如, 服务基站为终端配置了模式 1的资源分配方式, 但是 当该终端在该服务基站下发生了链路失败时,该终端无法继续用模式 1的方式来进行 通信。在发生链路失败后, 该终端进行连接重建, 然后在新的基站下进行通信。 但在 该过程中, 由于该终端得不到模式 1下的资源, 从而会发生通信业务的中断。
为了解决上述问题, 在 LTE-A系统中定义了异常场景。在异常场景发生后, 终端 可以自行决定采用何种资源分配方式来进行通信。例如, 在异常场景下, 如在链路失 败的情况下,在从终端触发连接重建开始直到终端成功选择到一个合适的小区并获取 到该小区广播的包含有设备到设备间通信的资源配置的系统信息期间,该终端可选择 采用模式 2的资源分配方式来进行通信,但是这种情况可能会导致如下问题: 该终端 的设备到设备间的通信对其他设备到基站间的上行数据通信造成强干扰,从而影响设 备到基站间的通信的正常进行。
为解决以上问题, 本发明实施例提供一种信息配置装置、 通信装置和通信系统, 可解决上述问题。
根据本发明实施例的第一方面, 提供一种信息配置装置, 该装置包括: 配置单元,该配置单元用于为终端配置在异常情况下进行设备与设备间的通信所 使用的资源池; 和 /或用于为终端配置在异常情况下、 该终端在预置的资源池中的资 源上进行设备与设备间的通信时发送数据所使用的功率控制参数。
根据本发明实施例的第二方面, 提供一种通信装置, 该装置包括:
通信单元, 该通信单元用于在异常情况下,选择在异常情况发生前终端所在的服 务小区的上行载波且利用该服务小区的基站配置的异常情况下、该终端进行设备与设 备间通信时使用的功率控制参数、 在该基站配置的资源池中的资源上发送数据。
根据本发明实施例的第三方面, 提供一种通信系统, 包括:
基站,该基站用于为终端配置在异常情况下进行设备与设备间的通信所使用的资 源池; 和 /或用于为终端配置在异常情况下、 该终端在配置的资源池中的资源上进行 设备与设备间的通信时发送数据使用的功率控制参数。 本发明实施例的有益效果在于: 网络侧的基站可为终端配置在异常情况下、该终 端进行设备与设备间的通信所使用的功率控制参数, 使得该终端在异常情况下,利用 该功率控制参数发送数据,这样, 可避免设备与设备间的通信对其他设备到基站间上 行数据通信造成强干扰, 使得设备到基站间的通信的正常进行。

在本实施例中, 以异常场景是发生链路失败的场景为例进行说明。
首先, 对在异常场景发生时, 终端自行决定所使用的资源分配方式, 如模式 2 的资源分配方式来进行通信所存在的问题进行分析。
例如,终端在发生链路失败后,会发起连接重建,如无线资源控制连接重建(RRC connection reestabl ishment ) ; 该重建的第一步是进行小区选择, 同时启动一个计 时器 T311 ; 在该终端选择到一个合适的小区后, 该终端停止该计时器 T311, 并触发 RRC连接重建请求消息 (RRCConnectionReestabl ishment Request ) 的发送, 同时启 动一个计时器 T301 ; 当收到基站发送的 RRC 连接重建成功消息 (RRCConnection Reestabl ishment ) 后, 该终端停止 T301的运行, 连接重建成功。 在计时器 T311和 T301运行期间, 为了保证通信业务的连续性, 终端可以选择使用模式 2来进行通信。
在从终端启动计时器 T311直到终端成功选择到一个合适的小区并获取到该小区 通过广播的包含有设备到设备间通信的资源配置的系统信息期间,该终端如果使用模 式 2的资源分配方式来进行通信,则一个需要解决的问题是该模式 2的资源池从何而 来。 目前采用的一种方法是: 该终端继续使用发生链路失败前终端所在的服务小区提 供的模式 2的资源池,这样会导致如下问题: 如果终端在当前的服务小区上发生链路 失败是由物理链路的问题导致, 即由 T310 超时导致的链路失败, 那么意味着接下来 该终端测得的该服务小区的路径损耗不可靠或者不准确,而该终端进行设备到设备间 的通信发送数据时的发送功率取决于该路径损耗。如果该终端测量得到的路径损耗不 可靠,那么在该终端仍旧利用该路径损耗来确定设备到设备间发送功率时, 该终端的 设备到设备间的通信就会对其他终端到基站间上行数据通信造成强干扰,从而影响终 端到基站间的通信的正常进行。
为了解决上述问题,本实施例提供一种信息配置方法和通信方法及其装置、 以及 通信系统, 以下结合附图对本发明实施例进行说明。 实施例 1
图 1是本发明实施例 1的信息配置方法流程图。 如图 1所示, 该方法包括: 步骤 101, 网络侧为终端配置在异常情况下、 该终端在预置的资源池中的资源上 进行设备与设备间的通信 (D2D通信) 所使用的功率控制参数。
在本实施例中, 该异常情况 (场景) 可为终端发起 RRC连接重建过程后, 从终 端启动计时器 T311直到终端成功选择到一个合适的小区并获取到该小区通过系统信 息广播的针对设备到设备间通信的资源配置期间。以下结合附图 2和 3对本实施例的 场景举例进行说明。
图 2是本发明实施例的一个场景的示意图。 如图 2所示, 在 T31 1启动后, 该终 端选择了一个合适的小区, 该终端停止该计时器 T311, 并获得该选择的小区广播的 包含针对 D2D通信的资源配置的系统信息。 如图 2所示, 将从终端启动计时器 T311 直到终端成功选择到一个合适的小区并获取到该小区通过系统信息广播的针对设备 到设备间通信的资源配置期间表示为时间段 。
图 3是本发明实施例的另一个场景的示意图。 如图 3所示, 直到 T31 1超时, 该 终端一直未选到合适的小区。在 T311超时后,该终端从 RRC连接态(RRC— CONNECTED) 转为 RRC空闲态(RRC— IDLE) , 然后在 RRC— IDLE状态下继续进行小区选择, 并成功选 择到一个小区并驻留在该小区。此后获取到该小区广播的包含针对 D2D通信的资源配 置的系统信息。 如图 3所示, 将从终端启动计时器 T311直到终端成功选择到一个合 适的小区并获取到该小区通过系统信息广播的针对设备到设备间通信的资源配置期 间表示为时间段 T2。 在本实施例中, 该预置的资源池是网络侧为该终端配置的资源 分配模式 2的资源池。 在这种情况下, 该方法还可包括:
步骤 102, 为该终端配置进行 D2D通信的资源池。
在一个实施例中,在步骤 102中, 网络侧为该终端配置的资源池可以是该终端在 异常和非异常情况时使用的资源池。因此,无论该终端处于异常情况还是非异常情况, 该终端均使用网络侧配置的同一个资源池中的资源进行 D2D通信。
在该一个实施例中, 在网络侧已为该终端配置了进行 D2D通信的资源分配模式 2 所对应的资源池时, 该终端即可使用目前网络侧已配置的资源池, 这样可省略步骤 102。
在另一个实施例中,在步骤 102中, 网络侧可为该终端分别配置该终端在异常情 况和非异常情况时使用的资源池, 这样, 该终端在异常情况和非异常情况下, 使用不 同的资源池中的资源。
在步骤 102中,网络侧也可以仅为该终端配置该终端在异常情况下所使用的资源 池, 而不配置该终端在非异常情况下所使用的资源池,将目前网络侧为该终端配置的 资源分配模式 2所对应的资源池作为非异常情况下所使用的资源池。
在本实施例中,网络侧还可为该终端配置该终端在非异常情况下进行 D2D通信使 用的功率控制参数。此外, 网络侧也可以不配置该功率控制参数, 而使用目前网络侧 为该终端配置的功率控制参数。其中, 网络侧为该终端配置的该终端在异常情况下使 用的功率控制参数与在非异常情况下使用的功率控制参数不同。
由上述可知, 如果使用目前网络侧, 如基站会为终端配置资源分配模式 2所对应 的资源池以及在该资源池的物理资源上进行数据发送时所对应的功率控制参数,则在 非异常情况下, 该终端进行 D2D通信时,利用该功率控制参数来计算得到在该物理资 源上发送数据时的发送功率值是没有问题的。 但是, 在上述异常情况下, 如果 D2D 通信仍旧利用该功率控制参数来计算得到在该物理资源上发送数据时的发送功率值, 则会导致得到的发送功率值偏大,从而对同一小区下面的设备到基站间的通信造成严 重干扰。 因此, 在本实施例中, 网络侧基站为该终端额外配置了在异常情况下进行 D2D通信所使用的功率控制参数, 这样, 在该终端处于异常情况时, 可使用该异常情 况下进行 D2D通信时所使用的功率控制参数进行数据发送,可避免设备与设备间的通 信对其他设备到基站间上行数据通信造成强干扰。
在本实施例中, 步骤 101和步骤 102 的顺序不限于本实施例, 还可先执行步骤
102, 再执行步骤 101, 或者同时执行步骤 101和 102。
在一个实施例中,在步骤 101中, 该网络侧为该终端配置的功率控制参数可为发 送功率值, 这样, 在异常情况下, 该终端进行 D2D通信时, 在需要发送数据时, 可直 接使用网络侧配置的该发送功率值来发送数据。
在另一个实施例中,在步骤 101中, 该网络侧为该终端配置的功率控制参数可为 用来确定该终端在该预置的资源池中的资源上进行设备与设备间的通信时发送数据 使用的发送功率值的相关参数。这样, 在异常情况下, 该终端进行 D2D通信时, 可利 用该相关参数计算在异常情况下该终端进行设备与设备间的通信时发送数据使用的 发送功率值, 并利用该发送功率值来发送数据。 这样,通过配置上述功率控制参数, 可避免设备与设备间的通信对其他设备到基 站间上行数据通信造成强干扰, 使得设备到基站间的通信的正常进行。
在本实施例中, 该相关参数可包括以下参数中的一个或一个以上:
最大传输功率值 PC 用于确定最大传输功率值( PCMAX )的参数( P-Max )、 目标接收功率 (Ρσ ) 和路损补偿因子 ( ac 路径损耗值 PLC
由上述实施例可知, 网络侧的基站可为终端配置在异常情况下、 该终端在模式 2 的资源池中的资源上进行设备与设备间的通信所使用的功率控制参数,使得该终端在 异常情况下, 利用该功率控制参数发送数据, 这样, 可避免设备与设备间的通信对其 他设备到基站间上行数据通信造成强干扰, 使得设备到基站间的通信的正常进行。

在本实施例中, 部件 402为可选部件,在网络侧已为该终端配置了进行 D2D通信 的资源分配模式 2所对应的资源池时, 该终端即可使用目前网络侧已配置的资源池, 这样部件 402可省略。
在另一个实施例中,第二配置单元 402为该终端分别配置该终端在异常情况下和 非异常情况下所使用的资源池。如实施例 1所述,第二配置单元 402也可不配置该终 端在非异常情况下所使用的资源池。
在本实施例中, 第二配置单元 402 还可配置在非异常情况下使用的功率控制参 数。但也可不配置该终端在非异常情况下使用的功率控制参数, 而将目前网络侧为该 终端配置的功率控制参数作为该终端在非异常情况下使用的功率控制参数。并且,该 终端在异常情况下使用的功率控制参数与非异常情况下使用的功率控制参数不同。
在本实施例中,第一配置单元 401和第二配置单元 402可通过高层信令配置上述 资源或功率控制参数, 如通过 RRC信令进行配置, 此处不再赘述。 这样, 在终端获得 上述参数后, 可在发生异常情况下、 进行 D2D通信时使用, 解决了现有技术中存在的 问题。

在另一个实施例中,针对异常情况和非异常情况, 该基站分别配置了各自的资源 池。这样, 该终端在异常情况下使用异常情况下的资源池中的资源进行 D2D通信, 而 在非异常情况下, 使用非异常情况下的资源池中的资源进行 D2D通信。具体如实施例 1所述, 将其内容合并于此, 此处不再赘述。

在本实施例中,在配置的异常情况下使用的功率控制参数为相关参数时,在该终 端进行 D2D通信时, 发生该异常情况后, 在需要发送数据时, 该终端在异常情况发 生前终端所在的服务小区的上行载波上,还可利用该服务小区的基站配置的异常情况 下用于确定该终端进行设备与设备间的通信时发送数据使用的发送功率值的相关参 数来确定发送功率值; 并且该终端还利用所确定的发送功率值、在该基站配置的资源 池中的资源上发送数据。 同样, 通过利用预先配置该相关参数获得发送功率值, 并利 用该发送功率值发送数据,可避免设备与设备间的通信对其他设备到基站间上行数据 通信造成强干扰, 保证设备到基站间的通信的正常进行。
在本实施例中, 该相关参数包括以下参数中的一个或一个以上:

/或 "和 时, 该终端可根据上述相关参数确定发送功率值 Ρ(Ζ')。
另外, 在网络侧未配置 Ρ(^, 但配置了 -Max时, 该终端可采用现有的任何一 种方式利用 -Max来获得 Ρ(¾«, 例如, 可利用参考文献 [36.101, V 12.1.0, User Equipment (UE ) radio transmission and reception]中的定义来得到 PcMAX, 然后再利用 该^^获得发送功率值 (ζ'), 现将该参考文献的内容合并于此, 此处不再赘述。
在本实施例中, 该方法还可包括: 在该终端发起 RRC连接重建过程后, 该终端 判断是否处于异常情况;
其中, 在该终端发起 RRC连接重建过程后, 该终端可判断是否处于从发起 RRC 连接重建开始到选择到一个合适的小区并获得该小区的基站广播的针对设备到设备 间的通信的资源配置的期间,在判断结果为是时,可判断为处于异常情况;反之亦然。
在本实施例中, 在该终端判断是否处于异常情况之前, 该方法还包括: 该终端判断该 RRC 连接重建的发起是否由物理层链路问题导致的无线链路失败 触发;
例如, 判断是否由于 T310超时导致。 如图 2和图 3所示, 在连续接收到 N310 个物理层失步指示信息后, 启动计时器 T310开始计时, 在连续收到 N311个物理层 同步指示信息后, 该计时器 T310停止。
在判断结果为是时, 再进一步判断该终端是否处于异常情况。
在上述实施例中, 在判断结果为处于异常情况时, 该终端执行步骤: 该终端在异 常情况发生前终端所在的服务小区的上行载波上,利用该服务小区的基站配置的异常 情况下该终端进行设备与设备间的通信时发送数据使用的功率控制参数、在该基站配 置的资源池的资源上发送数据。
由上述可知,在终端检测到其处于异常情况时, 可使用发生异常情况前终端所在 的服务小区的基站配置的功率控制参数、在该基站配置的模式 2的资源池中的资源上 进行 D2D通信,可避免设备与设备间的通信对其他设备到基站间上行数据通信造成强 干扰, 保证设备到基站间的通信的正常进行。
