A method and device for processing uplink synchronization information between a terminal and a secondary base station

Abstract

The invention provides a processing method and a processing apparatus for uplink synchronization information between a terminal and a SeNB, wherein the processing method comprises the following steps:after triggering a random access flow, feeding back a synchronization information indication which refers to an uplink synchronization result of the terminal to a MeNB; receiving an operation indication fed back by the MeNB according to the synchronization information indication; and performing corresponding resource service processing according to the operation indication. In the scheme providedby the invention, after the random access flow is triggered, the synchronization information indication (namely, adding handshaking information of the MeNB and the SeNB) which refers to the uplink synchronization result is fed back to the MeNB, thus, the MeNB is enabled to acquire the uplink synchronization information between the SeNB and the terminal in time; a condition that the MeNB triggersdata forwarding and path updating when uplink synchronization of the terminal and the SeNB is failed can be avoided; a condition that TDCoverall maintained by the SeNB is too long or too short also can be avoided; and a problem that an opportunity of executing follow-up flows by the MeNB or the SeNB is not accurate since the MeNB cannot obtain the uplink synchronization information of UE and the SeNB in the existing technology can be solved.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method and device for processing uplink synchronization information between a terminal and a secondary base station. Background technique [0002] With the continuous development of communication technology, users need the network to provide more convenient and faster large-traffic data communication services. In order to meet the needs of users, the communication network architecture needs to be continuously evolved and enhanced. In order to meet this requirement, the 3rd Generation Partnership Project (3GPP) proposed in R12 a network architecture in which several micro base stations are added within the coverage of a macro base station, which is the so-called dual connectivity (multi-connection) architecture. In this system, users can maintain connections with two (or more) base stations at the same time to perform uplink and downlink communications. Among the two...
