Translated fromChinese技术领域technical field
本发明涉及通信领域，具体涉及一种能力信息发送方法及系统。The present invention relates to the communication field, in particular to a method and system for sending capability information.
背景技术Background technique
目前，第三代伙伴组织计划(Third Generation Partnership Projects，简称为3GPP)推出高级长期演进(Long-Term Evolution advance，简称为LTE-Advanced)标准。LTE-Advanced对于长期演进(Long-Term Evolution，简称为LTE)的演进保留了LTE的核心，并在此基础上采用一系列技术对频域、空域进行了扩充，以达到提高频谱利用率、增加系统容量等目的。Currently, the Third Generation Partnership Projects (Third Generation Partnership Projects, 3GPP for short) launch the Long-Term Evolution advance (LTE-Advanced for short) standard. LTE-Advanced retains the core of LTE for the evolution of Long-Term Evolution (LTE for short), and uses a series of technologies to expand the frequency domain and air domain on this basis to improve spectrum utilization and increase system capacity, etc.
无线中继(Wireless Relay)技术即LTE-Advanced中的技术之一，旨在扩展小区的覆盖范围、减少通信中的死角地区、平衡负载、转移热点地区的业务和节省用户设备(User Equipment，简称UE)的发射功率。如图1所示，中继节点(Relay Node，简称RN)对接入其小区的UE提供与普通eNB类似的功能和服务，又通过无线接口以类似于普通UE的方式接入一个服务于它的eNB，服务于RN的eNB称为宿主基站(Donor eNB，简称DeNB)。不同于普通基站的有线S1、X2连接，RN与DeNB间建立的都是无线链路，其上承载所有的控制面信息。RN接入DeNB的过程简单描述如图2所示，包括：Wireless relay (Wireless Relay) technology is one of the technologies in LTE-Advanced. UE) transmit power. As shown in Figure 1, a relay node (Relay Node, referred to as RN) provides UEs accessing its cell with functions and services similar to ordinary eNBs, and accesses an eNB serving it through a wireless interface in a manner similar to ordinary UEs. The eNB serving the RN is called a Donor eNB (DeNB for short). Different from the wired S1 and X2 connections of ordinary base stations, all wireless links are established between RN and DeNB, on which all control plane information is carried. A brief description of the process of RN accessing DeNB is shown in Figure 2, including:
步骤201：RN从操作与维护(Operation and Maintenance，简称OAM)系统获取初始配置参数后接入到选择的DeNB，RN与DeNB间建立无线资源控制(Radio Resource Control，简称RRC)连接。当RN向DeNB回复无线资源控制连接建立完成(RRC Connection Setup Complete)消息时，消息中携带一个指示是否需要RN子帧配置的信元，该信元的出现即表明了这个节点是一个Relay节点，而是否需要子帧配置指明了该RN的类型；Step 201: The RN obtains initial configuration parameters from the Operation and Maintenance (OAM) system and accesses the selected DeNB, and establishes a Radio Resource Control (RRC) connection between the RN and the DeNB. When the RN replies to the DeNB with a radio resource control connection establishment complete (RRC Connection Setup Complete) message, the message carries an information element indicating whether RN subframe configuration is required. The appearance of this information element indicates that this node is a Relay node. And whether subframe configuration is required indicates the type of the RN;
步骤202：位于核心网侧的移动性管理实体(Mobility Management Entity，简称MME)等网元会对RN进行鉴权等操作，DeNB根据核心网回复的信息对RN作出相应的重配置；Step 202: Network elements such as the Mobility Management Entity (MME for short) located on the core network side will perform authentication and other operations on the RN, and the DeNB will reconfigure the RN accordingly according to the information returned by the core network;
步骤203：RN在与DeNB间的无线链路上建立S1(由此通过DeNB与核心网通信)、X2(由此通过DeNB与其他邻eNB通信)连接，连接建立后RN就可以为其下的UE提供与eNB类似的功能与服务了。Step 203: RN establishes S1 (thus communicating with the core network through DeNB) and X2 (thus communicating with other neighboring eNBs through DeNB) connections on the wireless link with DeNB. After the connection is established, RN can be its subordinate UE provides functions and services similar to eNB.
以现有的场景和需求来说，RN的部署是固定的，且不支持较为复杂的如载波聚合(Carrier Aggregation，简称CA)、多媒体广播多播业务(MultimediaBroadcast/Multicast Service，简称MBMS)等类的增强功能。然而，新场景及新业务的出现将会需求更大的吞吐量和更快的传输速率等多方面良好、稳定的性能，由此RN也需要如支持切换的移动性、支持MBMS和CA等增强功能等方面的升级。然而，RN升级后，仍然会出现RN升级的能力不能正常工作，DeNB无法进行相应操作的现象，反而使得系统性能下降了。In terms of existing scenarios and requirements, the deployment of RN is fixed, and does not support more complex types such as carrier aggregation (Carrier Aggregation, referred to as CA), multimedia broadcast multicast service (MultimediaBroadcast/Multicast Service, referred to as MBMS), etc. enhancements. However, the emergence of new scenarios and new services will require good and stable performance in many aspects such as greater throughput and faster transmission rates. Therefore, RN also needs enhancements such as mobility that supports handover, support for MBMS and CA, etc. Functional upgrades, etc. However, after the RN is upgraded, the ability to upgrade the RN will still fail to work normally, and the DeNB will not be able to perform corresponding operations, which will degrade the system performance instead.

具体实施方式Detailed ways
对现有技术分析发现，由于RN升级后，DeNB无法获知RN能力信息的更新变化，因此无法进行相应的操作，从而导致RN可支持的功能不能正常工作，使得系统的性能随之下降。The analysis of the existing technology found that after the RN is upgraded, the DeNB cannot know the update and change of the RN capability information, so it cannot perform corresponding operations, resulting in that the functions supported by the RN cannot work normally, resulting in a decrease in system performance.
为克服上述问题，本发明提供如下技术方案：In order to overcome the above problems, the present invention provides the following technical solutions:
RN将用于指示该RN当前能力信息的信元通过控制面信令发送给DeNB，该DeNB根据该信元对RN进行相应的配置和/或调度。The RN sends the information element used to indicate the current capability information of the RN to the DeNB through control plane signaling, and the DeNB performs corresponding configuration and/or scheduling on the RN according to the information element.
RN能够支持的功能可由该RN自身硬件直接获得，或从OAM下载获得，支持的功能例如为：支持移动切换、支持MBMS或支持CA等。The functions supported by the RN can be obtained directly from the RN's own hardware, or downloaded from the OAM. The supported functions are, for example: support for mobile handover, support for MBMS, or support for CA.
RN可以在接入DeNB的过程中或者在配置更新的过程中或者在RRC连接重建立过程中，将用于指示该RN当前能力信息的信元通过控制面信令发送给DeNB。The RN may send an information element indicating the current capability information of the RN to the DeNB through control plane signaling during the process of accessing the DeNB or during the process of updating the configuration or during the process of re-establishing the RRC connection.

所述用于指示该RN当前能力信息的信息可以是直接指示该RN具有某一功能的标识信息，如支持移动切换的标识信息；也可以是支持了某一功能后所需的独有配置的请求信息，DeNB接收该请求信息即可获知该RN的新能力，例如RN在支持了移动切换的功能后，RN需要自己独立的eNB身份标识(evolved NodeB Identifier，简称eNB ID)或其他独有的参数配置，则RN通过向DeNB请求其所需的eNB ID，使DeNB获知该RN是支持移动切换的，并为其分配eNB ID。The information used to indicate the current capability information of the RN may be identification information directly indicating that the RN has a certain function, such as identification information supporting mobile handover; it may also be a unique configuration required after a certain function is supported Request information, DeNB receives the request information to know the new capabilities of the RN. For example, after the RN supports the mobile handover function, the RN needs its own independent eNB identity (evolved NodeB Identifier, referred to as eNB ID) or other unique Parameter configuration, the RN requests the required eNB ID from the DeNB to let the DeNB know that the RN supports mobile handover and allocates an eNB ID for it.
对于DeNB而言，DeNB应能够识别接收到的信息并相应的作出应有的配置和/或调度，例如RN可支持移动切换，则RN请求需要自己的eNB ID，则DeNB知道该RN是可以支持移动切换的，并为其分配RN eNB ID和/或其他配置；同时DeNB需将指示移动相关信息(包括与小区重选相关的频率及重选参数等)的系统消息发送给RN，以使RN运用该移动切换功能。For DeNB, DeNB should be able to identify the received information and make appropriate configuration and/or scheduling accordingly, for example, RN can support mobile handover, then RN request requires its own eNB ID, then DeNB knows that the RN can support Mobile handover, and allocate RN eNB ID and/or other configurations; at the same time, DeNB needs to send system information indicating mobile related information (including frequency and reselection parameters related to cell reselection) to RN, so that RN Use the mobile toggle feature.
实现上述方法的系统包括第一装置和第二装置，其中：The system for implementing the above method includes a first device and a second device, wherein:

需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
实施例一Embodiment one
根据新场景(如高铁)和/或新业务的出现，RN也有了相应的能力更新升级。RN由自身硬件配置或从OAM下载获知新能力后，根据自身能够支持的功能，如移动切换、MBMS或CA等，RN在接入DeNB的过程中或配置更新的过程中，将用于指示自身能力信息的信元通过RRC消息发送给DeNB，DeNB根据这一信元对RN作出相应的配置与调度，以使RN的更新功能得以正确运用，满足场景及业务的需求，提高系统的整体性能。According to the emergence of new scenarios (such as high-speed rail) and/or new services, RN has corresponding capability updates and upgrades. After the RN acquires the new capability through its own hardware configuration or downloaded from OAM, according to the functions it can support, such as mobile handover, MBMS or CA, etc., the RN will use it to indicate itself during the process of accessing the DeNB or during the process of configuration update The information element of the capability information is sent to the DeNB through the RRC message, and the DeNB configures and schedules the RN according to this information element, so that the update function of the RN can be used correctly, meet the requirements of scenarios and services, and improve the overall performance of the system.
具体步骤如图3所示：The specific steps are shown in Figure 3:
步骤301：RN由自身硬件配置或从OAM下载获取新能力信息，已知自身可支持移动切换，则RN在接入DeNB的过程中，通过RRC消息将用于指示该RN当前能力信息的信元发送给DeNB；Step 301: RN configures its own hardware or downloads new capability information from OAM. Knowing that it can support mobile handover, RN sends the information element used to indicate the current capability information of the RN through the RRC message during the process of accessing the DeNB. Send to DeNB;
所述RRC消息可以是RRC Connection Setup Complete消息，也可以是RRC连接建立请求(RRC Connection Request)消息，或者是其他由RN发向DeNB的合适的RRC消息，甚至也可以是一条新的RRC消息。The RRC message may be an RRC Connection Setup Complete message, or an RRC Connection Setup Request (RRC Connection Request) message, or other appropriate RRC messages sent by the RN to the DeNB, or even a new RRC message.
所述用于指示该RN当前能力信息的信元可以是直接标注自身支持移动切换功能的标识信息，也可以是因支持移动切换功能而所需的与原普通RN不同的独有配置的请求信息，如移动RN需要的与DeNB不同的eNB ID的请求。The information element used to indicate the current capability information of the RN may be identification information that directly marks itself supporting the mobile handover function, or may be request information for a unique configuration different from the original common RN required to support the mobile handover function , such as a request for an eNB ID different from that of the DeNB required by the mobile RN.
步骤302：DeNB根据接收到的消息进行判断：如果是直接指示所支持功能的标识信息，则DeNB根据该标识信息作出相应的配置(例如若该RN指示自己可支持移动切换，则DeNB为其分配与自己不同的eNB ID)；如果指示RN需要自己独有的eNB ID的标识出现，即该信元为需要独有配置的请求，则DeNB获知该RN可支持移动切换，并对该RN分配其独有的eNB ID。Step 302: DeNB judges according to the received message: if it is the identification information directly indicating the supported function, then DeNB makes corresponding configuration according to the identification information (for example, if the RN indicates that it can support mobile handover, the DeNB assigns it eNB ID different from its own); if the identification indicating that the RN needs its own unique eNB ID appears, that is, the information element is a request for unique configuration, then the DeNB knows that the RN can support mobile handover, and assigns its own eNB ID to the RN Unique eNB ID.
为了统一流程，DeNB可以统一进行上述判断操作。或者，DeNB可以针对信元的不同进行不同的操作，例如，如果该信元为指示所述RN具有某一功能的标识信息，则DeNB根据RN支持的功能对该RN进行配置和调度；如果该信元为所述RN支持了某一功能后所需的独有配置的请求信息，则DeNB根据该请求判断RN所支持的功能，对该RN进行配置和调度。In order to unify the process, the DeNB may perform the above judgment operations in a unified manner. Or, the DeNB may perform different operations for different information elements, for example, if the information element is identification information indicating that the RN has a certain function, the DeNB configures and schedules the RN according to the functions supported by the RN; if the The information element is the unique configuration request information required after the RN supports a certain function, and the DeNB judges the function supported by the RN according to the request, and configures and schedules the RN.
DeNB将对RN的配置信息通知给RN，这个通知消息可以是RRC连接重配置(RRC Connection Reconfiguration)消息，也可以是其他某一从DeNB发往RN的RRC消息，甚至可以是S1或X2消息；RN接收后可能回复确认消息，如RRC连接重配置完成(RRC Connection Reconfiguration Complete)消息。The DeNB notifies the RN of the configuration information for the RN. This notification message can be an RRC Connection Reconfiguration (RRC Connection Reconfiguration) message, or some other RRC message sent from the DeNB to the RN, or even an S1 or X2 message; The RN may reply a confirmation message after receiving it, such as an RRC Connection Reconfiguration Complete (RRC Connection Reconfiguration Complete) message.
DeNB知道该RN可以支持移动切换后，就可以为其作出对应的配置及调度了，如RN可支持切换，则DeNB需将指示移动相关信息的系统消息发送给RN，以使RN得以正确的运用更新升级的功能，满足了网络的需求。After the DeNB knows that the RN can support mobile handover, it can make corresponding configuration and scheduling for it. If the RN can support handover, the DeNB needs to send a system message indicating mobile related information to the RN so that the RN can use it correctly. Update and upgrade functions to meet the needs of the network.
上述过程也可能发生在RN进行RRC连接重建立时，当RN与DeNB的连接出现了无线链路失败，则RN会发起RRC连接重建立，这个重建立可能是向原DeNB发起，但也有可能是其他DeNB，在该RRC连接重建立过程中，RN所支持的功能发生变化时，可在该RRC连接重建立过程中将用于指示该RN当前能力信息的信元发送给DeNB。The above process may also occur when the RN re-establishes the RRC connection. When the wireless link fails in the connection between the RN and the DeNB, the RN will initiate the RRC connection re-establishment. This re-establishment may be initiated to the original DeNB, but it may also be initiated by other DeNBs. , during the RRC connection re-establishment process, when the function supported by the RN changes, the information element used to indicate the RN's current capability information may be sent to the DeNB during the RRC connection re-establishment process.
实施例二Embodiment two
RN由自身硬件配置或从OAM下载获知新能力后，根据自身能够支持的功能，如移动切换、MBMS或CA等，RN在接入DeNB的过程中，将用于指示自身能力信息的信元通过S1消息发送给DeNB，DeNB根据这一信元对RN作出相应的配置与调度，以使RN的更新功能得以正确运用，满足场景及业务的需求，提高系统的整体性能。After the RN acquires new capabilities through its own hardware configuration or downloaded from OAM, according to the functions it can support, such as mobile handover, MBMS or CA, etc., the RN will pass the information element used to indicate its own capability information through The S1 message is sent to the DeNB, and the DeNB configures and schedules the RN according to this information element, so that the update function of the RN can be used correctly, meet the requirements of scenarios and services, and improve the overall performance of the system.
具体步骤如图4所示：The specific steps are shown in Figure 4:
步骤401：RN由自身硬件配置或从OAM下载获取新能力信息，已知自身可支持移动切换，则RN在接入DeNB的过程中，通过S1消息将用于指示该RN当前能力信息的信元发送给DeNB(根据现有架构，RN将DeNB视作自己的MME，与其建立S1连接)；Step 401: RN configures its own hardware or downloads new capability information from OAM. Knowing that it can support mobile handover, RN uses the S1 message to indicate the current capability information of the RN during the process of accessing the DeNB. Send it to DeNB (according to the existing architecture, RN regards DeNB as its own MME and establishes an S1 connection with it);
所述S1消息可以是S1建立请求(S1 SETUP REQUEST)消息，也可以是其他由RN发向DeNB的合适的S1消息，甚至也可以是一条新的S1消息。The S1 message may be an S1 setup request (S1 SETUP REQUEST) message, or other appropriate S1 messages sent from the RN to the DeNB, or even a new S1 message.
所述用于指示该RN当前能力信息的信元可以是直接标注自身支持移动切换功能的标识信息，也可以是因支持移动切换功能而所需的与原普通RN不同的独有配置的请求信息，如移动RN需要的与DeNB不同的eNB ID。The information element used to indicate the current capability information of the RN may be identification information that directly marks itself supporting the mobile handover function, or may be request information for a unique configuration different from the original common RN required to support the mobile handover function , such as the eNB ID required by the mobile RN and the DeNB.
步骤402：如果是直接指示支持功能的标识信息，则DeNB根据该标识信息作出相应的配置(例如若该RN指示自己可支持移动切换，则DeNB可能为其分配与自己不同的eNB ID)；如果指示RN需要自己独有的eNB ID的标识出现，则DeNB获知该RN可支持移动切换，并对该RN分配其独有的eNB ID；Step 402: If it is the identification information directly indicating the support function, the DeNB makes corresponding configurations according to the identification information (for example, if the RN indicates that it can support mobile handover, the DeNB may assign it a different eNB ID from itself); if When the sign indicating that the RN needs its own unique eNB ID appears, the DeNB knows that the RN can support mobile handover, and assigns its unique eNB ID to the RN;
DeNB将对RN的配置信息通知给RN，这个通知消息可以是S1消息，如S1建立响应(S1 SETUP RESPONSE)消息，也可以是其他某一从DeNB发往RN的S1消息，甚至可能是RRC消息或X2消息。The DeNB notifies the RN of the configuration information of the RN. This notification message can be an S1 message, such as an S1 setup response (S1 SETUP RESPONSE) message, or some other S1 message sent from the DeNB to the RN, or even an RRC message. or X2 messages.
实施例三Embodiment three
RN由自身硬件配置或从OAM下载获知新能力后，根据自身能够支持的功能，如移动切换、MBMS或CA等，RN在接入DeNB的过程中，将用于指示该RN当前能力信息的信元通过X2消息发送给DeNB，DeNB根据这一信元对RN作出相应的配置与调度，以使RN的更新功能得以正确运用，满足场景及业务的需求，提高系统的整体性能。After the RN acquires the new capability through its own hardware configuration or downloaded from OAM, according to the functions it can support, such as mobile handover, MBMS or CA, etc., the RN will use the information used to indicate the current capability information of the RN during the process of accessing the DeNB. The cell is sent to the DeNB through the X2 message, and the DeNB configures and schedules the RN according to the cell, so that the update function of the RN can be used correctly, meet the requirements of scenarios and services, and improve the overall performance of the system.
具体步骤如图5所示：The specific steps are shown in Figure 5:
步骤501：RN由自身硬件配置或从OAM下载获取新能力信息，已知自身可支持移动切换，则RN在接入DeNB的过程中，通过X2消息将用于指示该RN当前能力信息的信元发送给DeNB(根据现有架构，RN与DeNB间建立无线X2连接)；Step 501: RN configures its own hardware or downloads new capability information from OAM, and knows that it can support mobile handover, then in the process of accessing DeNB, RN sends the information element used to indicate the current capability information of the RN through the X2 message Send to DeNB (according to the existing architecture, a wireless X2 connection is established between RN and DeNB);
所述X2消息可以是X2建立请求(X2 SETUP REQUEST)消息，也可以是其他由RN发向DeNB的合适的X2消息，甚至可能是一条新的X2消息。The X2 message may be an X2 setup request (X2 SETUP REQUEST) message, or other suitable X2 messages sent from the RN to the DeNB, or even a new X2 message.
所述用于指示该RN当前能力信息的信元可以是直接标注自身支持移动切换功能的标识信息，也可以是因支持移动切换功能而所需的与原普通RN不同的独有配置的请求信息，如移动RN需要的与DeNB不同的eNB ID的请求。The information element used to indicate the current capability information of the RN may be identification information that directly marks itself supporting the mobile handover function, or may be request information for a unique configuration different from the original common RN required to support the mobile handover function , such as a request for an eNB ID different from that of the DeNB required by the mobile RN.
步骤502：如果是直接指示支持功能的标识信息，则DeNB根据该标识信息作出相应的配置(例如若该RN指示自己可支持移动切换，则DeNB可能为其分配与自己不同的eNB ID)；如果指示RN需要自己独有的eNB ID的标识出现，则DeNB获知该RN可支持移动切换，并对该RN分配其独有的eNB ID。Step 502: If it is the identification information directly indicating the support function, the DeNB makes corresponding configurations according to the identification information (for example, if the RN indicates that it can support mobile handover, the DeNB may assign it a different eNB ID from itself); if When the sign indicating that the RN needs its own unique eNB ID appears, the DeNB knows that the RN can support mobile handover, and allocates its unique eNB ID to the RN.
DeNB将对RN的配置信息通知给RN，这个通知消息可以是X2消息，如X2建立响应(X2 SETUP RESPONSE)消息，也可以是其他某一从DeNB发往RN的X2消息，甚至可能是RRC消息或S1消息。The DeNB will notify the RN of the configuration information of the RN. This notification message can be an X2 message, such as an X2 setup response (X2 SETUP RESPONSE) message, or another X2 message sent from the DeNB to the RN, or even an RRC message. or S1 message.
上述实施例虽然以RN具有新功能后向DeNB发送信元为例进行说明，但RN在未升级前也可以通过上述实施例将自己支持的功能信息发送给DeNB。Although the above embodiment is described by taking the RN sending information to the DeNB after having a new function as an example, the RN may also send the function information supported by itself to the DeNB through the above embodiment before being upgraded.
