Abstract: This application relates to wireless communication technologies, and more particularly, to a method, a apparatus and a system for transmitting a gateway address, which are used to solve the problem in the prior art that a DeNB is incapable of assisting an MME in selecting an SGW/PGW for a mobile relay node (RN). The method for transmitting a gateway address in an embodiment of this application comprises: a base station determining, when determining an access device to be a mobile RN, a gateway IP address of a mobility anchor serving as a gateway of the mobile RN; and sending the determined gateway IP address to a mobility management entity (MME) corresponding to the mobile RN. In the embodiment of this application, the DeNB is capable of assisting the MME in selecting a suitable mobility anchor for the mobile RN as the SGW/PGW, thereby guaranteeing normal work of the mobile RN.

Abstract: The present invention relates to communications technologies, and disclosed are a key updating method, device, and system. A local eNB monitors a user plane uplink and downlink PDCP COUNT value of each UE connected thereto, and transmits user plane uplink and downlink PDCP COUNT value information or transmits a key update request based on the PDCP COUNT value to a macro eNB, so that the macro eNB updates a key according to the key update request or the user plane uplink and downlink PDCP COUNT value information, thereby avoiding the problem of repeated use of security parameters, realizing prompt key update, and improving the security performance of the network.
Abstract translation: 本发明涉及通信技术，并且公开了一种关键的更新方法，设备和系统。 本地eNB监视与其连接的每个UE的用户平面上行链路和下行链路PDCP COUNT值，并发送用户平面上行链路和下行链路PDCP COUNT值信息，或者将基于PDCP COUNT值的密钥更新请求发送到宏eNB， 宏eNB根据密钥更新请求或用户平面上行链路和下行PDCP COUNT值信息更新密钥，从而避免重复使用安全参数的问题，实现提示密钥更新，提高网络的安全性能。
