摘要： A method of accessing in an equipment of a communication network is proposed in the invention. The method comprises the steps of: receiving a message 2 from a base station, the message 2 being used for an assignment of resource to transmit a message 3, the assigned resource corresponding to N HARQ RTTs, where 1≦N≦8; and transmitting the message 3 only in part of the N HARQ RTTs. With the scheme of the invention, a MTC device selectively transmits the Msg3 in one/some HARQ RTT and maintains silence in another one/some HARQ RTT, thus the possibility of the occurrence of access collision with other UEs may be backed off, such that other UEs, particularly human-to-human UEs, may transmit the Msg3 normally. And the possibility of the occurrence of collision is reduced from the viewpoint of the user equipments in a network, reducing entirely the possibility of an access delay and access failure.
摘要翻译：本发明提出了一种在通信网络的设备中进行访问的方法。该方法包括以下步骤：从基站接收消息2，消息2用于分配资源以发送消息3，所分配的资源对应于N个HARQ RTT，其中1 @ N @ 8; 并且仅在N个HARQ RTT的一部分中发送消息3。利用本发明的方案，MTC设备选择性地在一个/某个HARQ RTT中发送Msg3，并且在另一个/一些HARQ RTT中保持静默，因此可能会退出与其他UE发生访问冲突的可能性，使得其他UE，特别是人对人类UE可以正常地发送Msg3。并且，从网络中的用户设备的观点来看，发生冲突的可能性降低，从而完全减少了访问延迟和访问失败的可能性。

摘要： Discloses is a gateway, base station, communication network and synchronization method thereof. The method comprises: at time T1, sending from the gateway to the base stations a synchronization request signal; at time T2, receiving by the base stations the synchronization request signal; at time T3, sending from the base stations to the gateway the synchronization response comprising the times T2 and T3; at time T4, receiving by the gateway the synchronization response signals; and calculating for the base stations a mapping relationship between the time system of the gateway and the time system of the base station is calculated based on the times T1, T2, T3 and T4. With the configuration and method proposed in present invention, it can be avoided the problem that accurate synchronization between the gateway and the base stations can not be reached for MBMS data packets in LTE because of path delay and jitter error, so that every base station can specify the same transmitting time for MBMS data packets to guarantee that UE could implement correct RF combining.
