Description

信息处理方法及通信节点 技术领域
本申请涉及但不限于通信领域。
背景技术
随着无线多媒体业务的发展，人们对高数据速率和用户体验的需求日益增长，从而对传统蜂窝网络的***容量和覆盖提出了较高要求。另一方面社交网络、近距离数据共享、本地广告等应用的流行使得人们对了解附近感兴趣的人或事物并与之通信的需求逐渐增加。基于小区的蜂窝网络在高数据速率以及邻近服务的支持方面存在明显的局限性，在这种需求背景下，代表未来通信技术发展新方向的D2D(Device-to-Device，设备到设备)技术应运而生。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足上述高数据速率业务和邻近服务的要求。
D2D技术可以工作在授权频段或非授权频段，允许多个支持D2D功能的用户设备(即D2D用户设备，D2D User Equipment，D2D UE)在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。D2D的应用场景主要有三种：
1)UE1和UE2在蜂窝网络的覆盖下进行数据交互，用户面数据不经过网络基础设施，如图1的模式1；
2)在弱/无覆盖区域的UE中继传输，如图1中的模式2，允许信号质量较差的UE4通过附近有网络覆盖的UE3与网络进行通信，能帮助运营商扩展覆盖、提高容量。
3)在发生地震或紧急情况，蜂窝网络不能正常工作的情况下，允许设备间直接通信，如图1中的模式3，UE5，UE6和UE7间控制面和用户面都不经过网络基础设施而进行一跳或多跳的数据通信。
D2D技术通常包括D2D发现技术和D2D通信技术：
1)D2D发现技术是指用于判断/确定两个或多个D2D用户设备之间相互邻近(例如在可进行D2D直接通信范围之内)或用于判断/确定第一用户设备邻近第二用户设备的技术。
2)D2D通信技术是指D2D用户设备之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。
在图2和图3所示的应用场景中，D2D UE可以作为中继节点，使得蜂窝网络覆盖边缘或覆盖外的remote D2D UE能通过中继节点UE与网络进行蜂窝通信，且使得D2D UE间通过中继节点UE进行D2D通信。D2D UE有可能在蜂窝小区覆盖边缘移动，此时D2D UE需要更换其接入节点以接入网络，例如，通过中继UE中继的D2D UE移动到小区覆盖后可通过基站接入网络，小区覆盖内的通过基站接入网络的UE移动出小区覆盖后只能通过中继UE接入网络。而相关技术并未提供D2D UE的接入节点更换的方法，从而影响小区覆盖边缘UE的通信业务连续性。

本发明的实施方式
以下结合说明书附图及实施例对本发明的实施方式进行阐述。
方法实施例一：
如图4所示，本实施例还提供一种信息处理方法，所述方法包括：
步骤S310：接收第一基站发送的承载控制信息；
步骤S320：依据所述承载控制信息，更换到第二接入节点进行通信数据传输；
其中，所述第一基站为第一接入节点或第二接入节点；
所述第二接入节点为所述第一基站或D2D中继节点。
当所述第一D2D UE接入有两个接入节点或更换了接入节点之后，所述第一D2D UE在通信时存在着承载切换的需求。故本实施例所述提供一种更换到第二接入节点进行数据传输的信息处理方法，具有实现简便的优点。
当所述第一基站为第一接入节点时，所述第二接入节点可为D2D中继节点，该D2D中继节点可为第二D2D UE；当所述第一基站为第二接入节点时，所述第一接入节点可为D2D中继节点。所述第二D2D UE是不同于第一D2D UE的UE。
所述承载控制信息包括承载更换指示或承载切换判决参数信息。
所述承载更换指示用直接于指示第一D2D UE更换到通过第二接入节点进行通信数据传输；
所述承载切换判决参数信息用于所述第一D2D UE确定是否能够更换到所述第二接入节点进行通信数据传输。
所述承载切换判决参数信息包括所述第一D2D UE对服务小区、相邻小区的无线资源管理测量门限值及对第一中继节点及第二中继节点发送的信号的测量门限值的至少其中之一。所述第二中继节点为与所述第一中继节点的距离在指定范围内的中继节点；所述第一中继节点为与所述第一D2D UE连接的D2D中继节点，所述第二中继节点为未与所述第一D2D UE连接的D2D中继节点。
所述承载更换指示用于指示第一D2D UE是更换到通过第一基站或中继节点进行通信数据传输。这时第一基站可在接收到第一D2D UE发送的承载切换请求之后，可根据其自身或中继节点当前的负载，与第一D2D UE之间的信道的通信质量方式确定了是否允许所述第一D2D UE接入到所述第一基 站，若允许则所述第一基站会向所述第一D2D UE发送所述承载更换指示，从而所述第一D2D UE将会接收到所述承载更换指示；若不允许则所述第一D2D UE可能会直接从所述第一基站接收到承载更换请求失败的消息。故在种方式中，由第一基站来确定所述允许所述第一D2D UE切换到通过第一基站来进行网络的接入。
所述承载控制信息包括承载切换判决参数信息。所述承载切换判决参数信息包括无线资源管理RRM测量门限值及D2D通信的测量门限值的至少其中之一。这样第一D2D UE通过对第一基站发送的参考信号等信号测量，在依据所述测量门限进行判决后，可执行确定是否能够更换到所述第二接入节点进行通信数据传输。在本种方式中，是否能够更换到第二接入节点来进行通信数据传输是由测量结果和承载切换判决参数信息决定。
若所述第一基站发送的为承载更换指示，则所述第一基站还将自行进行是否允许所述第一D2D UE更换到第二接入节点进行承载切换的判断。
当所述第一D2D UE接收到所述承载切换判决参数信息之后，将自行进行是否能够将承载切换到第二接入节点的判定。如，所述第一D2D UE将对服务小区，和/或相邻小区，和/或第一中继节点及第二中继节点中进行测量，形成测量结果；所述第二中继节点为与所述第一中继节点的距离在指定范围内的中继节点；所述第一中继节点为与所述第一D2D UE连接的D2D中继节点，所述第二中继节点为未与所述第一D2D UE连接的D2D中继节点；并依据所述测量结果和所述承载切换判决参数信息进行对照，确定是否能够更换到所述第二接入节点进行通信数据传输。
如何对照，可以参照以下示例：
当第一D2D UE对服务小区和/或相邻小区和/或D2D中继节点的测量结果满足以下条件时确定通过基站传输蜂窝通信数据：
第一D2D UE接收到的承载切换判决参数信息中包含服务小区参考信号接收功率RSRP门限值，且所述服务小区的RSRP测量值高于所述门限值；
和/或，第一D2D UE接收到的承载切换判决参数信息中包含相邻小区RSRP门限值，且所述相邻小区的RSRP测量值高于所述门限值；
和/或，第一D2D UE接收到的承载切换判决参数信息中包含D2D中继节点的信号强度门限值，且所述D2D中继节点的信号质量测量值低于所述门限值。
在执行所述步骤S320之前，所述方法还可包括：
向第一基站发送承载切换判决辅助信息。
本实施例所述承载切换判决辅助信息，可用于为所述第一基站形成所述承载控制信息提供依据，如，为所述第一基站确定是否是向所述第一D2D UE发送承载切换指示还是发送承载切换请求失败提供依据，或如为所述第一基站确定RRM测量门限值及D2D通信的测量门限值提供依据；以便第一基站控制所述第一D2D UE的接入。
所述承载切换判决辅助信息包括以下的至少其中之一：UE到网络的中继指示信息、测量报告及位置信息；所述UE到网络的中继指示信息用于指示所述第一D2D UE当前通过UE到网络的中继进行数据传输；所述测量报告包含所述第一D2D UE对当前服务小区和/或相邻小区的RRM测量结果；所述位置信息包括所述第一D2D UE的当前地理位置信息。这些信息都能够帮助所述第一基站确定响应消息的内容。如，第一D2D UE的当前位置位于所述第一基站下的小区的边缘，此时若直接更换到第一基站来进行通信数据传输，则可能会导致通信效果差的问题，此时所述第一基站可以根据所述位置信息，形成不让所述第一D2D UE更换到第一基站接入网络的响应消息，或提高前述的RRM测量门限值。
若所述第一D2D UE需要向所述第一基站发送测量报告，则所述方法还包括：在所述UE向第一基站发送测量报告之前，接收第一基站发送的测量上报配置信息；根据所述测量上报配置信息进行信道测量，形成测量结果；当所述测量结果满足上报条件时，向第一基站发送所述测量报告。
此处的测量结果满足上报条件，可包括譬如信道测量发现第一基站发送的信号达到所述第一D2D UE的信号强度达到强度阈值等，但是不局限于此。
此外，所述承载控制信息包含D2D中继节点发现触发门限值；
所述D2D中继节点发现触发门限值用于触发所述第一D2D UE开启所述D2D中继节点发现，以寻找可供所述第一D2D UE接入的D2D中继节点。
所述D2D中继节点发现触发门限值包含第一门限值；
所述第一门限值，用于所述第一D2D UE对所述第一D2D UE所接入蜂窝小区的测量值小于所述第一门限值时，触发所述第一D2D UE开启所述D2D中继节点发现，寻找可供所述第一D2D UE接入的D2D中继节点。
所述第一门限值为参考信号接收功率((Reference Signal Received Power，简称为RSRP)值和参考信号接收质量(Reference Signal Received Quality，简称为RSRQ)值的至少其中之一。此处对所述第一小区的测量值为对所述第一小区所发送的信号的测量值，如第一小区发送的参考信号。
所述第一D2D UE将根据所述D2D中继节点发现触发门限值进行所述第一D2D UE所接入的蜂窝小区的测量，并形成测量值。所述蜂窝小区为基站形成的小区的统称，可包括所述第一D2D UE所接入的所述服务小区的所发送信号的测量。
所述D2D中继节点发现触发门限值还可包含第二门限值，
所述第一门限值和第二门限值，用于所述第一D2D UE对所述第一D2D UE所接入蜂窝小区的测量值小于所述第一门限值，并且对所述第一D2D UE所接入蜂窝小区的相邻小区的测量值小于所述第二门限值时，触发所述第一D2D UE开启D2D中继节点发现，寻找可供所述第一D2D UE接入的中继节点。
所述第二门限值可也以为所述RSRP值和/或RSRQ值。不同的是，所述第二门限值用于对所述第一D2D UE所接入小区的相邻小区的测量值的判断。这样所述第一D2D UE还将根据对服务小区的相邻小区进行测量，并进行比较判断来确定是否发现可供所述第一D2D UE接入的D2D中继节点。对所述第一D2D UE对接入蜂窝小区的测量，可包括对所述第一D2D UE对相应的蜂窝小区所发送的发现信号或参考信号的测量
发现所述D2D中继节点可通过相关技术中D2D发现过程来实现。
这样所述第一D2D UE还能根据所述承载控制信息发现能够使所述第一D2D UE接入的D2D中继节点。

所述第一基站可以通过广播或单播的方式来发送所述承载控制信息，可以将所述承载控制信息承载在小区信息中通过广播或单播的方式来发送，还可以通过将所述承载控制信息承载在专用随机接入接入资源信息中通过单播的方式来发送。所述承载控制信息可包括承载更换指示。所述承载更换指示用于指示第一D2D UE更换到通过第二接入节点进行通信数据传输。

所述承载切换判决参数信息包括所述第一D2D UE对服务小区、相邻小区的无线资源管理测量门限值及对第一中继节点及第二中继节点发送的信号的测量门限值的至少其中之一。所述第二中继节点为与所述第一中继节点的距离在指定范围内的中继节点；所述第一中继节点为与所述第一D2D UE连接的D2D中继节点，所述第二中继节点为未与所述第一D2D UE连接的D2D中继节点
本实施例所述方法还包括：接收所述第一D2D UE发送的承载切换判决辅助信息；所述步骤S410可包括：依据所述承载切换判决辅助信息，形成所述承载控制信息。
这样所述通信节点可以根据所述第一D2D UE发送的承载切换判决辅助信息来形成所述承载控制信息。
所述承载切换判决辅助信息包括以下的至少其中之一：
UE到网络的中继指示信息、测量报告及位置信息；
所述UE到网络的中继指示信息用于指示所述第一D2D UE当前通过UE到网络的中继进行数据传输；

本发明实施例还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行上述信息处理方法。
以下结合上述任一实施例提供两个应用示例：
示例一：
本示例描述是由中继UE的远距离UE移动到基站的覆盖范围后，转换为通过基站接入网络的方法流程。图6为本示例所述方法的流程示意图，本实施例方法包括以下步骤：
步骤401：当前场景下，远距离UE通过中继UE与eNB进行数据传输，中继UE可通过广播方式发送辅助信息，以辅助远距离UE更快的检测到附近的小区。如，辅助信息为中继UE所在小区或相邻小区或邻近小区的信息。小区信息可包括以下之一或组合，频点，小区标识，小区接入禁止指示，小区接入概率参数。
小区接入禁止指示用于指示该小区不允许接入，例如，在该小区的负荷较重的情况下。小区接入概率参数也可用于控制接入该小区的UE数，例如，小区接入概率参数取值范围为0-1，远距离UE可选取一个范围为0-1的随机数，若该随机数小于小区接入概率参数，则远距离UE认为可接入该小区，若该随机数大于等于小区接入概率参数，则远距离UE认为不接入该小区。
中继UE可根据服务小区和/或相邻小区的***消息SIB中广播的接入等级禁止(Access Class Barring，ACB)参数值获知服务小区和/或相邻小区的负荷状况。另外，出于负载均衡考虑，中继UE可仅将负荷相对较轻的所在 小区/相邻小区信息广播发送给远距离UE。例如，若中继UE所在小区负荷较重(中继UE可根据接入等级AC参数判断)，则可指示中继UE所在小区接入禁止或广播接入概率参数，或不广播中继UE所在小区的频点/物理小区标识PCI信息，以避免UE检测以及尝试接入到中继UE所在小区。
另外，除了由中继UE广播发送的方式，辅助信息还可由远距离UE主动向中继UE请求获得。例如，远距离UE检测到其正在进入蜂窝小区覆盖范围时向中继UE请求辅助信息。
步骤402：若远距离UE想要执行非竞争的RA过程，可向中继UE请求专用RA资源。所述专用RA资源包括专用随机接入前导，专用时频域资源。
步骤403：可选的，中继UE收到专用RA资源请求后，可向基站请求用于远距离UE的专用RA资源。
步骤404：若基站接收到专用RA资源请求，则可将用于远距离UE的专用RA资源发送给中继UE。
步骤405：中继UE接收到基站为远距离UE分配的专用RA资源后，将该专用资源发送给远距离UE。
步骤406：远距离UE根据从中继UE接收的辅助信息和/或专用RA资源检测到可用的蜂窝小区，并接入该小区。如图8中的远距离UE检测到蜂窝小区并接入基站。
步骤407：可选的，远距离UE可向所接入的基站发送UE到网络中继指示，用于指示该远距离UE正在通过中继UE的UE到网络的中继接入网络。可选的，远距离UE还可将所接入的中继UE信息(如标识)，该远距离UE的位置信息告知基站。可选的，远距离UE还可将其对中继UE以及服务小区/相邻小区的测量结果上报给基站。远距离UE发送测量报告给基站之前可接收到基站发送的测量上报配置信息，并根据所述测量上报配置信息，在满足测量上报条件时，将测量结果上报给基站。可选的，远距离UE可向基站发送承载切换请求，请求转换为通过基站接入进行通信数据传输。
步骤408：基站确定该远距离UE可将承载切换至基站，也即通过基站 接入网络进行通信数据传输，则向UE发送承载切换指示，用于指示UE由通过D2D中继节点的通信数据传输转换为通过基站的通信数据传输。
步骤408’：或者，基站可广播承载切换判决参数信息，用于远距离UE判断是否执行承载切换，即由通过中继UE接入的通信数据传输转换至通过基站接入的通信数据传输。该承载切换判决参数信息包括以下之一或组合：UE对服务小区和/或相邻小区的RRM测量门限值；UE与D2D中继节点之间的D2D通信的测量门限值。
注：该步骤可替代步骤407和步骤408，也即，若基站广播切换判决参数，则UE不需要向基站上报UE到网络中继指示，基站不需要执行承载切换判决并向UE发送承载切换指示，而是由UE自身确定是否通过基站进行数据传输。
步骤409：若远距离UE接收到承载切换指示，则确定通过基站传输蜂窝通信数据。
步骤410：远距离UE发起EPS承载建立过程。或者，若远距离UE接收到承载切换判决参数信息，则UE根据其对服务小区和/或相邻小区和/或D2D中继节点的测量结果自行确定是否基站传输蜂窝通信数据。若测量结果满足预定义准则，则确定通过基站传输蜂窝通信数据，并发起演进的分组***(Evolved Packet System，EPS)承载建立过程。
步骤411：可选的，远距离UE可向中继UE发送中继连接释放消息以告知中继UE；或者，中继UE可在激活定时器(接收到或向远距离UE发送D2D数据时开启/重启)超时后释放其与远距离UE之间的连接。
示例二：
本实施例描述的是通过基站接入的UE移动出基站的覆盖范围后，转换为通过中继UE的UE到网络的中继接入网络的方法流程。图8为本实施例方法的流程示意图，如图7所示，本实施例方法包括以下步骤：
步骤501：UE通过基站接入网络并进行数据传输。当UE往蜂窝小区覆盖范围外移动的过程中，UE可向基站发送中继节点接入请求指示，以向基 站请求转换为通过D2D中继节点接入的通信方式，可选的，UE还可将UE已接入的D2D中继节点标识或UE检测到的D2D中继节点信息(如标识信息)上报给基站。
步骤502：可选的，UE可将其当前位置信息，或者其对所接入中继UE，服务小区，相邻小区的测量结果上报给基站。
步骤503：基站确定需为该UE转换为通过中继UE的UE到网络中继的接入网络，并为该UE选择一个中继UE。可选的，基站可根据UE上报的信息执行判决并选择中继UE。如步骤501所述，UE上报的信息可包括以下之一或组合：中继节点接入请求指示，UE已接入的D2D中继节点标识或UE检测到的D2D中继节点信息(如标识信息)，UE当前位置信息，或者UE对所接入中继UE，服务小区，相邻小区的测量结果。
步骤504：基站向所选择的D2D中继节点发送中继接入请求消息。该中继接入请求消息中可包含：远距离UE的标识信息，远距离UE的通信业务QoS需求信息，D2D安全能力信息，D2D安全相关参数信息，远距离UE的D2D通信组标识信息，远距离UE所请求的D2D中继类型(即UE到中继网络)，远距离UE的优先级信息，远距离UE所在D2D通信组的优先级信息，远距离UE的D2D通信业务的优先级信息，远距离UE与中继UE之间D2D通信的配置信息。其中，远距离UE的通信业务QoS需求信息可包含服务质量等级标识(QoS Class Identifier，QCI)，分配/预留优先级(Allocation and Retention Priority ARP)，是否为保证比特速率(Guaranteed Bit Rate，GBR)，最大比特速率(Maximum Bit Rate，MBR)等信息。其中，远距离UE与中继UE之间D2D通信的配置信息可包含D2D通信承载配置信息，安全相关配置信息等。所述QoS为服务质量的缩写
步骤505：中继UE接收中继接入请求消息后需执行接纳控制，判断是否允许远距离UE通过中继UE的中继接入网络。中继UE可根据自身的中继能力，收发能力，已经接入的D2D UE数量，优先级信息，D2D UE的通信业务QoS需求等信息确定是否允许D2D UE1接入。若中继UE允许远距离UE接入，则发送中继接入响应消息给基站。该中继接入响应消息中可包含：远距离UE的标识信息，远距离UE与中继UE之间D2D通信的配置信 息。其中，远距离UE与中继UE之间D2D通信的配置信息可包含D2D通信承载配置信息，安全相关配置信息等。若中继UE不允许远距离UE接入，则向基站回复拒绝消息，基站可为远距离UE选择其它的候选中继UE。
步骤506：基站收到中继接入响应消息后，向远距离UE发送接入节点更换信息以命令远距离UE接入中继UE。该接入节点更换信息中可包含：要接入的D2D中继节点信息，远距离UE与中继UE间D2D通信可使用的D2D通信资源信息,远距离UE与中继UE间D2D通信的D2D通信承载配置信息,承载切换指示。其中，远距离UE与中继UE之间D2D通信的配置信息可包含D2D通信承载配置信息，安全相关配置信息等；承载切换指示用于指示UE是否由通过基站的通信数据传输转换为通过中继UE的通信数据传输。
步骤507：若远距离UE确认通过中继UE的中继接入网络进行蜂窝通信，则向基站发送确认消息。
步骤508：该远距离UE可通过中继UE的数据转发进行蜂窝通信。
示例一和示例二的基站均可为前述第一基站，所述中继UE即为前述实施例中的第二D2D UE。所述远距离UE即为前述实施例中的远距离UE。
