Abstract

Provided are a carrier aggregation (CA) method, related equipment and system. The CA method comprises: a first base station receives indication information transmitted by a second base station; and the first base station transmits a radio resource connection (RRC) reconfiguration message to a terminal, the RRC reconfiguration message being used to instruct the terminal to delete at least one configuration borne by the terminal with respect to the second base station. In an embodiment of the present invention, if a general packet radio system tunneling protocol (GTP) error is borne by the second base station, all of the bearers of the first base station and the second base station are not necessarily released, and only a bearer with a GTP error of the second base station is released, or only a bearer of the second base station is released, thus avoiding a link interruption between the base station and the terminal, and reducing the amount of control signaling data in the process of releasing and re-establishing a bearer, thereby improving user data transmission efficiency, and improving user experience.

Description

一种载波聚合方法、相关设备以及系统Carrier aggregation method, related device and system技术领域Technical field

本发明涉及通信技术领域，尤其涉及的是一种载波聚合方法、相关设备以及系统。The present invention relates to the field of communications technologies, and in particular, to a carrier aggregation method, related device, and system.

背景技术Background technique

随着移动通信系统的发展，系统能够提供的服务质量越来越高。为保持3GPP的长期竞争优势，LTE Release-12的标准制定工作正在进行。Release-12版本的一个重要特性是支持基站间的载波聚合(CA，Carrier Aggregation)，即用户设备(User Equipment，UE)可以同时使用属于多个基站的多个小区进行通信，从而支持高速数据传输，提高UE的峰值传输速率。当前该特征在标准上的讨论课题是双连接(DC，Dual Connectivity for LTE)或小区增强(SCE，Small Cell Enhancement)。With the development of mobile communication systems, the quality of services that the system can provide is getting higher and higher. In order to maintain the long-term competitive advantage of 3GPP, the standardization of LTE Release-12 is underway. An important feature of the Release-12 version is to support carrier aggregation (CA) between base stations. User equipment (UE) can simultaneously use multiple cells belonging to multiple base stations to communicate, thereby supporting high-speed data transmission. To improve the peak transmission rate of the UE. The current topic of discussion of this feature in the standard is dual connectivity (DC, Dual Connectivity for LTE) or cell enhancement (SCE, Small Cell Enhancement).

对一个UE来说，在这多个服务基站中，其中一个是主基站(MeNB，Master eNB)，其他是辅基站(SeNB，Secondary eNB)。主基站和辅基站都会和UE进行数据传输，两者主要的区别在于，主基站承担更多的控制功能，比如主基站和MME间有S1-MME连接，所有S1-MME的信令终结于MeNB，即涉及和MME间信令的交互都有主基站负责完成；另外，主基站负责与UE之间的空中接口的控制信令(RRC消息)交互，如果辅基站需要修改辅基站的RRC配置参数，则必须请求主基站，经由主基站的空口来修改。For one UE, one of the multiple serving base stations is a primary base station (MeNB, Master eNB), and the other is a secondary base station (SeNB, Secondary eNB). Both the primary base station and the secondary base station perform data transmission with the UE. The main difference between the two is that the primary base station bears more control functions. For example, there is an S1-MME connection between the primary base station and the MME, and all S1-MME signaling ends in the MeNB. That is, the interaction between the signaling involved with the MME is performed by the primary base station; in addition, the primary base station is responsible for the control signaling (RRC message) interaction with the air interface between the UE, if the secondary base station needs to modify the RRC configuration parameter of the secondary base station. Then, the primary base station must be requested to be modified via the air interface of the primary base station.

对于承载类型可分为三种：一种为：MCG(Master Cell Group，主小区组)承载，该承载的数据直接通过MeNB在UE和服务网关SGW间传递；第二种为：SCG(Secondary Cell Group，辅小区组)承载，该承载的数据通过SeNB在UE和SGW间传递；第三种为：Split Bearers，分流承载，该承载的数据同时通过MeNB以及SeNB和UE间传递，并经由MeNB和SGW间传递。例如：对于下行数据，下行数据通过S1-U先到达MeNB，MeNB决定分流部分数据并通过X2-U传递至SeNB，SeNB将该部分数据下发给UE。目前SGW和eNB的S1-U，MeNB和SeNB的X2-U接口上的数据都是通过GTP(General Packet Radio System Tunnelling Protocol，通用分组无线系统隧道协议)传输的。每个承载的上行或者下行数据有单独的GTP隧道，通过TEID(Tunnel Endpoint IDentifier r，隧道端点标识)来区分。The bearer type can be divided into three types: one is: MCG (Master Cell Group) bearer, and the data of the bearer is directly transmitted between the UE and the serving gateway SGW through the MeNB; the second type is: SCG (Secondary Cell) Group, the secondary cell group), the data of the bearer is transmitted between the UE and the SGW through the SeNB; the third type is: Split Bearers, the offload bearer, the data of the bearer is simultaneously transmitted between the MeNB and the SeNB and the UE, and is transmitted through the MeNB and Pass between SGWs. For example, for the downlink data, the downlink data first arrives at the MeNB through the S1-U, and the MeNB determines the offloaded part of the data and transmits the data to the SeNB through the X2-U, and the SeNB sends the partial data to the UE. Currently, the data on the S2-U of the SGW and the eNB, and the X2-U interface of the MeNB and the SeNB are transmitted through the GTP (General Packet Radio System Tunneling Protocol). EachThe uplink or downlink data of the bearer has a separate GTP tunnel, which is distinguished by the TEID (Tunnel Endpoint IDentifier r).

根据3GPP TS 23.007的规定，MeNB和SeNB都与SGW间有S1-U连接，即MCG承载和SCG承载。但SGW不会识别承载类型(MCG还是SCG承载)，即基站间载波聚合技术对SGW是透明的。当SeNB或MeNB检测到一个SCG承载的GTP错误时，发送GTP Error Indication(GTP错误指示)给SGW，SGW将不仅删除所涉及承载，而是删除包含MCG承载在内的所有该UE所有的TEID，并发送下行数据通知消息(Downlink Data Notification)给MME，MME触发UE上行文释放流程，并试图重建给UE，即发送寻呼消息给UE。现有技术所造成的主要问题是当不管MCG承载还是SCG承载中任何一个承载发生GTP错误时，都将造成所有承载以及UE的连接释放，必将严重影响用户体验。According to the provisions of 3GPP TS 23.007, both the MeNB and the SeNB have an S1-U connection with the SGW, that is, an MCG bearer and an SCG bearer. However, the SGW does not identify the bearer type (MCG or SCG bearer), that is, the inter-base station carrier aggregation technology is transparent to the SGW. When the SeNB or the MeNB detects a GTP error of an SCG bearer, it sends a GTP Error Indication to the SGW. The SGW deletes all the TEIDs of the UE including the MCG bearer. And sending a downlink data notification message (Downlink Data Notification) to the MME, the MME triggers the UE uplink text release process, and attempts to reestablish the UE, that is, sends a paging message to the UE. The main problem caused by the prior art is that when any GTP error occurs in any one of the MCG bearer and the SCG bearer, all bearers and the connection of the UE will be released, which will seriously affect the user experience.
