<p>A synchronization method and synchronization apparatus are disclosed. The method includes: detecting if user is out of synchronization status in uplink; if yes, downlink dispatch entity triggering uplink enhanced random access synchronization procedure; uplink dispatch entity obtaining the user identifier transmitted by user who is triggered uplink synchronization, and informing that user already restored uplink synchronization by interaction with downlink dispatch entity. The method and apparatus may shorten effectively synchronization delay, improve transmission efficiency of data and utilization rate of system resource, and ensure natural sending and transmission by using enhanced random access technique of system in prior art and by interaction between uplink dispatch entity and downlink dispatch entity to finish uplink synchronization.</p> |
