Abstract: The present disclosure provides a method, a system, and an apparatus for transmitting group communication service data. In the present disclosure, the LTE uses a multimedia broadcast and multicast service (MBMS) to transmit group communication system enabler (GCSE) service data, a multi-cell/multicast coordination entity (MCE) knows whether a multimedia broadcast single frequency network (MBSFN) transmission mode or a single cell multicast transmission mode is used to transmit the GCSE service data. Whether the MBSFN transmission mode or the single cell multicast transmission mode is used to transmit the GCSE service data is determined based on UE capability information and UE location information. When the single cell multicast transmission mode is used, the MCE instructs an eNodeB (eNB) to use the single cell multicast transmission mode to transmit the GCSE service data. The present disclosure saves LTE air interface resources.

Abstract: A method for supporting indication of a failure event to a source access system is provided. The method includes notifying, by the source access system, information of a source cell to a target access system, routing, by the target access system, a message to the base station or the base station controller of the source access through a core network by use of the information of the source cell received from the source access system when the target access system needs to transmit a message to the source access system. By use of the method provided by the present disclosure, a problem of mobility robustness optimization (MRO) among different radio access technology (RAT) may be notified to the source access system, so as to avoid impact for a terminal, reduce operator configuration.

Abstract: The present application discloses a method for a master eNB (MeNB) handover or a secondary eNB (SeNB) handover in a small cell system, comprising: sending by a source MeNB information of a source secondary cell (Scell) to a target MeNB; sending by the target MeNB a message to the source MeNB, the message notifying the source MeNB to suspend data transmission on a bearer of the SeNB. Until a message of data transmission resuming is received, the data transmission/reception is started to continue. The method for a MeNB handover or a SeNB handover provided in the present application may reduce the reconfiguration of the bearer for the UE, avoid releasing the bearer by error, and improve the system throughput and the data rate of transmission.
Abstract translation: 本申请公开了一种用于小型小区系统中的主eNB（MeNB）切换或二次eNB（SeNB）切换的方法，包括：将来自源二次小区（Scell）的源MeNB信息发送到目标MeNB; 由目标MeNB向源MeNB发送消息，该消息通知源MeNB暂停在SeNB的承载上的数据传输。 在接收到数据发送恢复的消息之前，数据发送/接收开始继续。 本申请中提供的用于MeNB切换或SeNB切换的方法可以减少用于UE的承载的重新配置，避免由于错误而释放承载，并提高系统吞吐量和传输数据速率。

Abstract: The present disclosure discloses cache-based data transmission methods and apparatuses. The method is implemented as follows. An apparatus where a caching node is located reports a caching capability to a network side, and the caching node is configured to cache data. The network side sends a cache indicating parameter to the apparatus where the caching node is located, and maintains a data list. Wherein, the cache indicating parameter is configured to control the caching node to cache the data which has the property of high repetition probability and/or high cache utilization, and the data list is a list of the data cached in the caching node. When the caching node has cached data requested by a UE, the UE obtains the requested data from the caching node.
Abstract translation: 本公开公开了一种基于高速缓存的数据传输方法和装置。 该方法实现如下。 高速缓存节点所在的装置向网络侧报告缓存能力，并且缓存节点被配置为缓存数据。 网络侧向高速缓存节点所在的设备发送缓存指示参数，并维护数据列表。 其中，缓存指示参数被配置为控制高速缓存节点来缓存具有高重复概率和/或高缓存利用率的属性的数据，并且数据列表是缓存在高速缓存节点中的数据的列表。 当高速缓存节点缓存由UE请求的数据时，UE从缓存节点获取所请求的数据。
