技术领域technical field
本发明涉及无线通信领域，并且更具体地，涉及上行链路变更的方法、装置及系统。The present invention relates to the field of wireless communication, and more particularly, to a method, device and system for uplink modification.
背景技术Background technique
在3GPP(3rd Generation Partnership Project，第三代移动通信标准化的伙伴项目)的技术演进中，为了增强业务上行数据量和上行业务覆盖，考虑引入上行多小区HSUAP(High Speed Uplink Packet Access，高速上行链路分组接入协作技术)，也称为MC-HSUPA，即在数据上行方向上，将工作在多个不同载频上的数据信道捆绑在一起传输数据，一个UE(User Equipment，用户设备)可以同时发送多个载频上数据信道的数据。In the technical evolution of 3GPP (3rd Generation Partnership Project, the third-generation mobile communication standardization partner project), in order to enhance the service uplink data volume and uplink service coverage, the introduction of uplink multi-cell HSUAP (High Speed Uplink Packet Access, high-speed uplink MC-HSUPA, also known as MC-HSUPA, that is, in the data uplink direction, data channels working on multiple different carrier frequencies are bundled together to transmit data, and a UE (User Equipment, user equipment) can Simultaneously transmit data on data channels on multiple carrier frequencies.
上行双小区HSUPA，也就是上行DC-HSUPA(Dual Cell HSUPA)是在两个工作在不同上行载频上的小区上同时建立UE和基站的连接，使UE发送的上行数据可以同时通过与上述两个小区建立的连接发送。Uplink dual-cell HSUPA, that is, uplink DC-HSUPA (Dual Cell HSUPA), is to simultaneously establish a connection between the UE and the base station on two cells operating on different uplink carrier frequencies, so that the uplink data sent by the UE can pass through the above two Connections established by cells are sent.
在上行双小区HSUPA操作中，协作的两个小区分为主小区和辅小区，网络侧需要依据一定的控制策略，激活或者去激活上行辅载波，即启动和停止信令或者数据在上行辅小区的发送，来提高整个系统资源的利用率。例如，网络侧可以根据上行传输的数据量、上行服务辅小区的信道条件、上行干扰状况以及服务辅小区有无变更等情形，来决定执行激活还是去激活上行辅载波操作。初始配置上行双小区HSUPA操作时，上行辅小区为去激活状态，后续网络侧可以根据情况，激活或者去激活上行辅小区。In the uplink dual-cell HSUPA operation, the two coordinated cells are divided into the primary cell and the secondary cell. The network side needs to activate or deactivate the uplink secondary carrier according to a certain control strategy, that is, start and stop signaling or data in the uplink secondary cell to improve the utilization of system resources. For example, the network side may decide to activate or deactivate the uplink secondary carrier operation according to the amount of uplink transmitted data, the channel condition of the uplink serving secondary cell, the uplink interference situation, and whether the serving secondary cell has changed. When the uplink dual-cell HSUPA operation is initially configured, the uplink secondary cell is in the deactivated state, and the subsequent network side can activate or deactivate the uplink secondary cell according to the situation.
当RNC(Radio Network Controller，无线网络控制器)在一个Node B(基站)中初始建立上行辅载波链路的时候，可以通过消息指示上行辅载波链路的激活状态。当上行主载波链路或上行辅载波链路变更导致新建上行主载波链路，或者导致上行辅载波链路激活或者去激活时，或者当在一个Node B中仅建立上行辅载波链路时，或者在一个Node B中仅存在上行辅载波链路，需要添加新上行辅载波链路或者重配置已有上行辅载波链路时，RNC无法有效通知Node B上行链路变更。When an RNC (Radio Network Controller, radio network controller) initially establishes an uplink secondary carrier link in a Node B (base station), it may indicate the activation status of the uplink secondary carrier link through a message. When the change of the uplink primary carrier link or the uplink secondary carrier link leads to the creation of an uplink primary carrier link, or the activation or deactivation of the uplink secondary carrier link, or when only the uplink secondary carrier link is established in a Node B, Or there is only an uplink secondary carrier link in a Node B, and when a new uplink secondary carrier link needs to be added or an existing uplink secondary carrier link needs to be reconfigured, the RNC cannot effectively notify the Node B of the uplink change.

具体实施方式detailed description
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。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

基站，可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本发明并不限定，但为描述方便，下述实施例以Node B为例进行说明。The base station can be a base station (NodeB) in WCDMA, and can also be an evolved base station (eNB or e-NodeB, evolutional Node B) in LTE. The present invention is not limited, but for the convenience of description, the following embodiments use Node B is taken as an example for illustration.
本发明实施例解决了当上行链路变更导致上行辅载波激活或者去激活时，或者当在一个Node B中仅建立上行主载波链路或者上行辅载波链路时，或者在一个Node B中仅存在上行辅载波链路，需要添加新上行辅载波链路或者重配置已有上行辅载波链路时，RNC如何通知Node B上行主载波链路或上行辅载波链路变更的问题。The embodiment of the present invention solves the problem that when the uplink secondary carrier is activated or deactivated due to the change of the uplink, or when only the uplink primary carrier link or the uplink secondary carrier link is established in a Node B, or only the uplink secondary carrier link is established in a Node B When there is an uplink secondary carrier link and it is necessary to add a new uplink secondary carrier link or reconfigure an existing uplink secondary carrier link, how does the RNC notify the Node B of the change of the uplink primary carrier link or the uplink secondary carrier link.
另外，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。Additionally, the terms "system" and "network" are often used herein interchangeably. The term "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship.
本发明实施例上下文中的非服务基站为用户设备的非服务Node B，服务基站为所述用户设备的服务Node B，且上下文中的上行链路从技术角度来说包括上行主载波链路和上行辅载波链路，但依据本发明实施例中的具体应用，上行链路可以指代上行主载波链路或上行辅载波链路，需要具体情况具体分析。The non-serving base station in the context of the embodiment of the present invention is the non-serving Node B of the user equipment, the serving base station is the serving Node B of the user equipment, and the uplink in the context includes the uplink primary carrier link and the The uplink secondary carrier link, but according to the specific application in the embodiment of the present invention, the uplink may refer to the uplink primary carrier link or the uplink secondary carrier link, which requires specific analysis of specific situations.
图1是根据本发明实施例上行链路变更的方法10的流程图。作为一种实现方式，实施方法10的装置可以为RNC。Fig. 1 is a flowchart of a method 10 for uplink change according to an embodiment of the present invention. As an implementation manner, the device implementing method 10 may be an RNC.
11，当用户设备与非服务基站之间不存在上行主载波链路时，确定所述用户设备与所述非服务基站间的上行主载波链路或上行辅载波链路需要变更。11. When there is no uplink primary carrier link between the user equipment and the non-serving base station, determine that the uplink primary carrier link or the uplink secondary carrier link between the user equipment and the non-serving base station needs to be changed.
RNC通过维护的信元可以确定用户设备与非服务基站之间不存在上行主载波链路。The RNC can determine that there is no uplink primary carrier link between the user equipment and the non-serving base station through the maintained information element.
所述上行链路变更上下文中也简称为链路变更或变更，不但可以包括上行辅载波链路的激活状态的变更，还可以包括建立上行主载波链路或者上行辅载波链路、添加上行辅载波链路或重配置上行辅载波链路的同时，执行上行主载波链路或者上行辅载波链路的激活状态的变更等。需要通知变更的应用场景可以包括，但不限于以下情形。In the context of the uplink change, it is also referred to as link change or change for short, which may not only include the change of the activation status of the uplink secondary carrier link, but also include the establishment of the uplink primary carrier link or the uplink secondary carrier link, and the addition of uplink secondary carrier links. While the carrier link or the uplink secondary carrier link is reconfigured, the activation state of the uplink primary carrier link or the uplink secondary carrier link is changed, etc. The application scenarios that need to be notified of changes may include, but are not limited to the following situations.
1、UE上报事件，请求RNC添加一个辅载波非服务小区至辅载波激活集，RNC确定后，决定添加所请求的小区至辅载波激活集，并通知所请求的小区所在的Node B，该Node B此时尚未与UE建立上行载波链路或仅建立有上行辅载波链路。1. The UE reports an event and requests the RNC to add a secondary carrier non-serving cell to the secondary carrier active set. After the RNC confirms, it decides to add the requested cell to the secondary carrier active set, and notifies the Node B where the requested cell is located. At this time, B has not yet established an uplink carrier link or only established an uplink secondary carrier link with the UE.
2、当服务Node B激活或者去激活UE的上行辅载波链路后，会通过Secondary UL Frequency Update(上行辅载波更新)消息通知服务RNC当前上行辅载波链路激活状态，服务RNC确定需要通知非服务Node B上行辅载波激活状态的变更，所述非服务Node B当前仅存在上行辅载波链路。2. When the serving Node B activates or deactivates the UE's uplink secondary carrier link, it will notify the serving RNC of the current uplink secondary carrier link activation status through the Secondary UL Frequency Update (uplink secondary carrier update) message, and the serving RNC determines that it is necessary to notify the UE The serving Node B changes the activation state of the uplink secondary carrier, and the non-serving Node B currently only has an uplink secondary carrier link.
3、UE上报事件，请求RNC添加一个主载波非服务小区至主载波激活集，RNC确定后，决定添加所请求的小区至主载波激活集，并通知所请求的小区所在的Node B，该Node B此时尚未与UE建立上行载波链路。3. The UE reports the event and requests the RNC to add a primary carrier non-serving cell to the primary carrier active set. After the RNC confirms, it decides to add the requested cell to the primary carrier active set, and notifies the Node B where the requested cell is located. B has not yet established an uplink carrier link with the UE at this time.
13，向非服务基站发送与变更相对应的无线链路管理消息，所述无线链路管理消息携带链路激活状态的指示信息。13. Send a radio link management message corresponding to the change to the non-serving base station, where the radio link management message carries link activation state indication information.
无线链路管理消息可以包括无线链路建立(Radio Link Setup)消息、无线链路添加(Radio Link Addition)消息或无线链路重配置(Radio LinkReconfiguration)消息等。The radio link management message may include a radio link setup (Radio Link Setup) message, a radio link addition (Radio Link Addition) message, or a radio link reconfiguration (Radio LinkReconfiguration) message, and the like.
根据确定的需要变更的上行链路的不同，例如上行主载波链路或上行辅载波链路，链路激活状态的指示信息可以包括：指示上行主载波链路为激活状态，或者指示上行辅载波链路为激活状态，或者指示上行辅载波链路为去激活状态等。According to the determined uplink that needs to be changed, such as the uplink primary carrier link or the uplink secondary carrier link, the indication information of the link activation status may include: indicating that the uplink primary carrier link is activated, or indicating the uplink secondary carrier link The link is in an activated state, or indicates that the uplink secondary carrier link is in a deactivated state, etc.
可选的，如果需要变更的链路为上行主载波链路，无线链路管理消息可以只携带第一指示信息，而不携带链路激活状态的指示信息。这是因为NodeB或者DRNC接收到无线链路激活消息后，根据第一指示信息，获知变更的链路为主载波链路，由于主载波链路总是激活状态，从而间接知道链路激活状态为激活。Optionally, if the link that needs to be changed is the uplink primary carrier link, the radio link management message may only carry the first indication information instead of the link activation state indication information. This is because after NodeB or DRNC receives the wireless link activation message, according to the first indication information, it knows that the changed link is the main carrier link. Since the main carrier link is always activated, it indirectly knows that the link activation status is activation.
本发明实施例实现通过确定用户设备上行主载波链路/上行辅载波链路需要链路变更，发送与所述链路变更相对应的无线链路管理消息，所述无线链路管理消息携带链路激活状态的指示信息，可以提高RNC通知Node B上行主载波激活状态或上行辅载波激活状态的灵活性和Iub接口资源的使用效率。The embodiment of the present invention realizes that by determining that the uplink primary carrier link/uplink secondary carrier link of the user equipment requires a link change, and sending a radio link management message corresponding to the link change, the radio link management message carries a link The indication information of the channel activation status can improve the flexibility of the RNC to notify the Node B of the activation status of the uplink primary carrier or the activation status of the uplink secondary carrier and the utilization efficiency of Iub interface resources.
图2是根据本发明实施例上行链路变更的方法200的交互图。Fig. 2 is an interaction diagram of a method 200 for uplink modification according to an embodiment of the present invention.
实施例1，210，UE向RNC发送测量报告，请求RNC添加一个辅载波非服务小区至上行辅载波激活集。Embodiment 1. In 210, the UE sends a measurement report to the RNC, requesting the RNC to add a secondary carrier non-serving cell to the uplink secondary carrier active set.
RNC管理基站的上行主载波激活集和上行辅载波激活集。The RNC manages the active set of the uplink primary carrier and the active set of the uplink secondary carrier of the base station.
上行主载波激活集可以包括上行主载波服务小区和上行主载波非服务小区或仅包括上行主载波服务小区。所辖上行主载波服务小区的基站或所辖上行主载波非服务小区的基站分别与UE存在上行主载波服务链路或上行主载波非服务链路，两者均可以称为上行主载波链路。The active set of the uplink main carrier may include the serving cell of the uplink main carrier and the non-serving cell of the uplink main carrier, or only include the serving cell of the uplink main carrier. The base station of the serving cell of the uplink primary carrier under its jurisdiction or the base station of the non-serving cell of the uplink primary carrier under its jurisdiction has an uplink primary carrier service link or an uplink primary carrier non-serving link with the UE, both of which can be called uplink primary carrier links .
上行辅载波激活集可以包括上行辅载波服务小区和上行辅载波非服务小区或仅包括上行辅载波服务小区。所辖上行主载波服务小区的基站或所辖上行主载波非服务小区的基站分别与UE存在上行辅载波服务链路或上行辅载波非服务链路，两者均可以称为上行辅载波链路。The active set of the uplink secondary carrier may include the serving cell of the uplink secondary carrier and the non-serving cell of the uplink secondary carrier or only include the serving cell of the uplink secondary carrier. The base station of the serving cell of the uplink primary carrier or the base station of the non-serving cell of the uplink primary carrier under its jurisdiction has an uplink secondary carrier service link or an uplink secondary carrier non-serving link with the UE, both of which can be called uplink secondary carrier links .
210所添加的辅载波非服务小区为非服务基站所辖。The secondary carrier non-serving cell added in 210 is under the jurisdiction of the non-serving base station.
215，RNC当UE与非服务基站间不存在上行主载波链路和上行辅载波链路时，确定需要建立上行辅载波链路。215. The RNC determines that an uplink secondary carrier link needs to be established when there is no uplink primary carrier link and uplink secondary carrier link between the UE and the non-serving base station.
RNC通过维护的信元可以确定UE与非服务基站之间不存在上行主载波链路和上行辅载波链路。The RNC can determine that there is no uplink primary carrier link and uplink secondary carrier link between the UE and the non-serving base station through the maintained information element.
220，向非服务基站发送无线链路建立消息，所述无线链路建立消息携带链路激活状态的指示信息。220. Send a radio link establishment message to a non-serving base station, where the radio link establishment message carries link activation state indication information.
由于UE与非服务基站间不存在上行主载波链路和上行辅载波链路，RNC需要建立UE与非服务基站间的第一条上行辅载波链路。与此情况对应的无线链路消息为无线链路建立消息。在RNC和Node B之间的Iub接口采用无线链路建立消息来完成链路建立，在此消息中，主载波配置信元位置处增加一个信元，用于指示非服务Node B，上行辅载波激活状态为激活或者去激活。如果当前上行辅载波为去激活，则所述链路激活状态的指示信息为去激活状态；或如果当前上行辅载波为激活，则所述链路激活状态的指示信息为激活状态。Since there is no uplink primary carrier link and uplink secondary carrier link between the UE and the non-serving base station, the RNC needs to establish the first uplink secondary carrier link between the UE and the non-serving base station. The wireless link message corresponding to this situation is a wireless link establishment message. The Iub interface between RNC and Node B uses a wireless link establishment message to complete the link establishment. In this message, an information element is added at the position of the main carrier configuration information element, which is used to indicate the non-serving Node B, the uplink auxiliary carrier The activation status is active or deactivated. If the current uplink secondary carrier is deactivated, the indication information of the link activation state is a deactivated state; or if the current uplink secondary carrier is activated, the indication information of the link activation state is an activated state.
可选的，在主载波配置信源处还可以增加一个链路所属载波信息，上下文中称为第二信息，用于指示所属载波为辅载波，也就是指示所建立的上行链路为上行辅载波链路。当基站收到该第二信息时，可以直接得知与UE待建立的上行链路为上行辅载波链路，而不需要通过其他方式间接获知，这样能够提高后续利用该信息的工作效率。Optionally, information about the carrier to which the link belongs may also be added at the primary carrier configuration information source, which is referred to as second information in the context, which is used to indicate that the carrier to which the link belongs is a secondary carrier, that is, to indicate that the established uplink is an uplink secondary carrier. carrier link. When the base station receives the second information, it can directly know that the uplink to be established with the UE is an uplink secondary carrier link without indirect knowledge through other means, which can improve the subsequent work efficiency of using the information.
作为本发明实施例的另一选择，上述步骤210至220中，在实施例2中，不同的是，UE请求RNC添加一个主载波非服务小区至上行主载波激活集，上述实施例1的内容相应地改动如下。As another option of the embodiment of the present invention, in the above-mentioned steps 210 to 220, in the second embodiment, the difference is that the UE requests the RNC to add a primary carrier non-serving cell to the uplink primary carrier active set, the content of the above-mentioned embodiment 1 Change accordingly as follows.
210，UE向RNC发送测量报告，请求RNC添加一个主载波非服务小区至上行主载波激活集。210. The UE sends a measurement report to the RNC, requesting the RNC to add a primary carrier non-serving cell to the active set of the uplink primary carrier.
210所添加的主载波非服务小区为非服务基站所辖。The main carrier non-serving cell added in 210 is under the jurisdiction of the non-serving base station.
215，RNC当UE与非服务基站间不存在上行主载波链路和上行辅载波链路时，确定需要建立上行主载波链路。215. The RNC determines that an uplink primary carrier link needs to be established when there is no uplink primary carrier link and uplink secondary carrier link between the UE and the non-serving base station.
RNC通过维护的信元可以确定UE与非服务基站之间不存在上行主载波链路和上行辅载波链路。The RNC can determine that there is no uplink primary carrier link and uplink secondary carrier link between the UE and the non-serving base station through the maintained information element.
220，向非服务基站发送无线链路建立消息，所述无线链路建立消息携带链路激活状态的指示信息。220. Send a radio link establishment message to a non-serving base station, where the radio link establishment message carries link activation state indication information.
由于UE与非服务基站间不存在上行主载波链路和上行辅载波链路，RNC需要建立UE与非服务基站间的第一条上行主载波链路。与此情况对应的无线链路消息为无线链路建立消息。在RNC和Node B之间的Iub接口采用无线链路建立消息来完成链路建立，在此消息中，主载波配置信元位置处增加一个信元，用于指示非服务Node B，上行主载波激活状态为激活。可选的，在主载波配置信源处还可以增加一个链路所属载波信息，上下文中称为第一信息，用于指示所属载波为主载波，也就是指示所建立的上行链路为上行主载波链路。当基站收到该第一信息时，可以直接得知与UE待建立的上行链路为上行辅载波链路，而不需要通过其他方式间接获知，这样能够提高后续利用该信息的工作效率。Since there is no uplink primary carrier link and uplink secondary carrier link between the UE and the non-serving base station, the RNC needs to establish the first uplink primary carrier link between the UE and the non-serving base station. The wireless link message corresponding to this situation is a wireless link establishment message. The Iub interface between RNC and Node B uses the wireless link establishment message to complete the link establishment. In this message, an information element is added at the location of the main carrier configuration information element, which is used to indicate the non-serving Node B, the uplink main carrier Activation status is active. Optionally, information about the carrier to which the link belongs may also be added at the primary carrier configuration information source, which is referred to as the first information in the context, which is used to indicate that the carrier to which the link belongs is the primary carrier, that is, to indicate that the established uplink is the primary uplink carrier link. When the base station receives the first information, it can directly know that the uplink to be established with the UE is an uplink secondary carrier link without indirect knowledge through other means, which can improve the subsequent work efficiency of using the information.
可选的，如果需要变更的链路为上行主载波链路，无线链路管理消息可以只携带第一指示信息，而不携带链路激活状态的指示信息。这是因为NodeB或者DRNC接收到无线链路激活消息后，根据第一指示信息，获知变更的链路为主载波链路，由于主载波链路总是激活状态，从而间接知道链路激活状态为激活。Optionally, if the link that needs to be changed is the uplink primary carrier link, the radio link management message may only carry the first indication information instead of the link activation state indication information. This is because after NodeB or DRNC receives the wireless link activation message, according to the first indication information, it knows that the changed link is the main carrier link. Since the main carrier link is always activated, it indirectly knows that the link activation status is activation.
由于215和220的实施条件不同，作为与实施例1或2不同的另一实施例，225取代215，且230取代220。Since the implementation conditions of 215 and 220 are different, as another embodiment different from Embodiment 1 or 2, 225 replaces 215, and 230 replaces 220.
在225，RNC确定UE与非服务基站间不存在上行主载波链路，仅存在上行辅载波链路时，确定需要通知添加上行辅载波链路。At 225, the RNC determines that there is no uplink primary carrier link between the UE and the non-serving base station, and only an uplink secondary carrier link exists, and determines that it is necessary to notify to add an uplink secondary carrier link.
接下来，230，向非服务基站发送无线链路添加消息，所述无线链路添加消息携带上行辅载波链路激活状态的指示信息。Next, at 230, send a radio link addition message to the non-serving base station, where the radio link addition message carries indication information of an activation state of the uplink secondary carrier link.
由于UE与非服务基站间不存在上行主载波链路，且存在上行辅载波链路，RNC需要添加UE与非服务基站间的另一条上行辅载波链路。与此情况对应的无线链路消息为无线链路添加消息。在RNC和Node B之间的Iub口采用无线链路添加消息来完成链路添加，在此消息中，主载波配置信元位置处增加一个信元，用于指示非服务Node B，上行辅载波链路的激活状态为激活或者去激活。Since there is no uplink primary carrier link and an uplink secondary carrier link between the UE and the non-serving base station, the RNC needs to add another uplink secondary carrier link between the UE and the non-serving base station. The wireless link message corresponding to this case adds a message for the wireless link. The Iub interface between RNC and Node B uses the wireless link addition message to complete the link addition. In this message, an information element is added at the position of the main carrier configuration information element to indicate the non-serving Node B, the uplink auxiliary carrier The activation state of the link is active or deactivated.
具体来说，上述方法的225和230可以应用到以下场景：Specifically, 225 and 230 of the above method can be applied to the following scenarios:
例如，接收到UE在210发送的测量报告和服务基站发送的上行辅载波更新(Secondary UL Frequency Update)消息，如图2的240所示，则RNC确定所述用户设备与所述非服务基站间的上行辅载波链路需要变更。其中，上行辅载波更新消息通知RNC上行辅载波链路激活状态为激活或去激活。For example, after receiving the measurement report sent by the UE at 210 and the uplink secondary carrier update (Secondary UL Frequency Update) message sent by the serving base station, as shown in 240 in FIG. The uplink secondary carrier link needs to be changed. Wherein, the uplink secondary carrier update message notifies the RNC that the link activation state of the uplink secondary carrier is activated or deactivated.
或者，当用户设备与非服务基站之间不存在上行主载波链路，RNC通过UE在210上报的测量报告，确定需要将主载波服务小区和辅载波服务小区变更至其他小区，或者辅载波服务小区变更至其他小区，变更后以辅载波激活集外的第一小区取代原辅载波服务小区后，删除原辅载波服务小区，则RNC确定所述用户设备与所述非服务基站间的上行辅载波链路需要变更，该变更是指上行辅载波激活状态变为去激活。Or, when there is no uplink primary carrier link between the user equipment and the non-serving base station, the RNC determines that the serving cell of the primary carrier and the serving cell of the secondary carrier need to be changed to other cells through the measurement report reported by the UE at 210, or that the secondary carrier serves The cell is changed to another cell, after the change, the original secondary carrier serving cell is replaced by the first cell outside the secondary carrier active set, and the original secondary carrier serving cell is deleted, then the RNC determines the uplink secondary carrier between the user equipment and the non-serving base station The carrier link needs to be changed, and the change means that the activation status of the uplink secondary carrier changes to deactivation.
如果上述220或230还涉及到RNC之间的Iur接口操作，则需要在SRNC(Serving RNC，服务RNC)向DRNC(Drifting RNC，漂移RNC)发送的无线链路建立消息或无线链路添加消息中的主载波信元位置处同样携带相应的信元，以使DRNC向所辖的非服务Node B发送的无线链路建立消息或无线链路添加消息中携带链路激活状态的指示信息，可选的，还可以携带链路所属载波信息，也就是上述第一信息或第二信息。其中，对于一个具体的UE来说，RNC可以分为SRNC和DRNC。SRNC在所述UE与核心网(CN，CoreNetwork)的连接中，对所述UE的所有资源进行控制，直接与CN相连。DRNC在所述UE与核心网(CN，Core Network)的连接中，仅为所述UE提供资源，与CN没有相连。If the above-mentioned 220 or 230 also involves the Iur interface operation between RNCs, it needs to be included in the radio link establishment message or radio link addition message sent by SRNC (Serving RNC, serving RNC) to DRNC (Drifting RNC, drifting RNC) The corresponding information element is also carried at the position of the main carrier information element of the main carrier, so that the wireless link establishment message or the wireless link addition message sent by the DRNC to the non-serving Node B under its jurisdiction carries the indication information of the link activation status, optional , it may also carry information about the carrier to which the link belongs, that is, the above-mentioned first information or second information. Wherein, for a specific UE, RNC can be divided into SRNC and DRNC. The SRNC controls all resources of the UE during the connection between the UE and a core network (CN, CoreNetwork), and is directly connected to the CN. The DRNC only provides resources for the UE during the connection between the UE and a core network (CN, Core Network), and is not connected to the CN.
本发明实施例实现通过确定用户设备上行主载波链路/上行辅载波链路需要链路变更，发送与所述链路变更相对应的无线链路管理消息，所述无线链路管理消息携带链路激活状态的指示信息，可以提高RNC通知Node B上行主载波/上行辅载波激活状态的灵活性和Iub接口资源的使用效率。The embodiment of the present invention realizes that by determining that the uplink primary carrier link/uplink secondary carrier link of the user equipment requires a link change, and sending a radio link management message corresponding to the link change, the radio link management message carries a link The indication information of the channel activation state can improve the flexibility of the RNC to notify the Node B of the activation state of the uplink main carrier/uplink auxiliary carrier and the utilization efficiency of Iub interface resources.
图3是根据本发明另一实施例上行链路变更的方法300的交互图。Fig. 3 is an interaction diagram of a method 300 for uplink modification according to another embodiment of the present invention.
310，服务基站(服务Node B)向RNC发送上行辅载波更新消息。310. The serving base station (serving Node B) sends an uplink secondary carrier update message to the RNC.
当服务基站激活或者去激活UE的上行辅载波链路后，会通过上行辅载波更新消息通知服务RNC上行辅载波激活状态变更。After the serving base station activates or deactivates the uplink secondary carrier link of the UE, it will notify the serving RNC of the change of the activation state of the uplink secondary carrier through an uplink secondary carrier update message.
320，当UE与非服务基站间不存在上行主载波链路，且存在上行辅载波链路时，确定非服务基站上行辅载波链路需要变更。320. When there is no uplink primary carrier link and an uplink secondary carrier link exists between the UE and the non-serving base station, determine that the non-serving base station needs to change the uplink secondary carrier link.
RNC需要通知非服务基站已建立的上行辅载波链路的激活状态变更。The RNC needs to notify the non-serving base station of the activation state change of the established uplink secondary carrier link.
330，RNC向非服务基站发送无线链路重配置消息，所述无线链路重配置消息携带重配置的上行辅载波链路的激活状态指示信息，在RNC和Node B之间的Iub接口，通过无线链路重配置消息，通知非服务基站(此Node B与UE之间仅存在上行辅载波链路)上行辅载波链路为激活或去激活。此消息中，在主载波配置信元位置处增加一个信元用于指示上行辅载波激活状态。330. The RNC sends a radio link reconfiguration message to the non-serving base station, the radio link reconfiguration message carries the activation state indication information of the reconfigured uplink secondary carrier link, and is passed through the Iub interface between the RNC and the Node B The radio link reconfiguration message notifies the non-serving base station (there is only an uplink secondary carrier link between the Node B and the UE) that the uplink secondary carrier link is activated or deactivated. In this message, an information element is added at the location of the main carrier configuration information element to indicate the activation state of the uplink auxiliary carrier.
如果330还涉及到RNC之间的Iur口操作，则需要在SRNC向DRNC发送的无线链路重配置消息中的主载波信元位置处同样携带相应的信元，以使DRNC向所辖的非服务Node B发送无线链路重配置消息中携带上行辅载波激活状态的指示信息。If 330 also involves the Iur interface operation between RNCs, it is necessary to carry corresponding information elements at the position of the main carrier information element in the radio link reconfiguration message sent by the SRNC to the DRNC, so that the DRNC can report The serving Node B sends the radio link reconfiguration message carrying the indication information of the activation state of the uplink secondary carrier.
由于实施条件不同，作为本发明另一实施例，340替代了310。Due to different implementation conditions, as another embodiment of the present invention, 340 replaces 310.
340，UE向RNC发送测量报告。340. The UE sends a measurement report to the RNC.
RNC从测量报告中获知：用户设备与非服务基站之间不存在上行主载波链路时，确定需要将主载波服务小区和辅载波服务小区变更至其他小区，或者辅载波服务小区变更至其他小区，变更后以辅载波激活集外的第一小区取代原辅载波服务小区后，删除原辅载波服务小区。于是，RNC在320中确定非服务基站上行辅载波变更。接下来，RNC在330中向非服务基站发送无线链路重配置消息。The RNC learns from the measurement report that when there is no uplink primary carrier link between the user equipment and the non-serving base station, it is determined that the serving cell of the primary carrier and the serving cell of the secondary carrier need to be changed to other cells, or the serving cell of the secondary carrier is changed to another cell After the change, the original auxiliary carrier serving cell is replaced by the first cell outside the active set of the auxiliary carrier, and the original auxiliary carrier serving cell is deleted. Then, in 320, the RNC determines the change of the uplink secondary carrier of the non-serving base station. Next, the RNC sends a radio link reconfiguration message to the non-serving base station in 330 .
本发明实施例实现通过确定用户设备上行辅载波链路需要链路变更，发送与所述链路变更相对应的无线链路管理消息，所述无线链路管理消息携带链路激活状态的指示信息，可以提高RNC通知Node B上行辅载波激活状态的灵活性和Iub接口资源的使用效率。The embodiment of the present invention realizes that by determining that the uplink secondary carrier link of the user equipment needs a link change, and sending a radio link management message corresponding to the link change, the radio link management message carries link activation state indication information , which can improve the flexibility of the RNC to notify the Node B of the activation status of the uplink secondary carrier and the utilization efficiency of the Iub interface resources.
