Abstract

The embodiment of the present invention provides a data transmission method and base station. The method comprises the steps of: establishing a forward channel between a target base station of user equipment and a source base station of the user equipment by the target base station; determining forward delay between the target base station and the source base station by the target base station; and determining duration of an endmark timer according to the forward delay by the target base station.

Description

Data transmission method and base station

Technical field

The present invention relates to the communications field, and more specifically, relate to a kind of data transmission method and base station.

Background technology

In Long Term Evolution (Long Term Evolution, LTE) handoff procedure, realize harmless switching, the data cached of the source base station of subscriber equipment will be forwarded to target BS side and send to subscriber equipment.In target BS side, before completing, switching needs Buffer forwarding data.After having switched, target BS preferentially sends forwarding data to subscriber equipment, sends the new data that starts to send core net after forwarding data again and be sent to target BS.

In handover execution stage, target BS triggering core net is carried out the path handover operation of subscriber equipment, and core net is carried out the path handover operation of downlink data, and the data that are sent to subscriber equipment are sent to target BS.For being sent to the data (being forwarding data) of source base station and being sent to the separation of the data (new data) of target BS, core net is used end mark (Endmark) mark, while there is link switching again, core net sends end mark mark (this end mark mark is sent to target BS by source base station again) to source base station, is then switched to new chain road direction target BS and sends new data.

Target BS is receiving after forwarding data, start end mark timer, if receive the end mark message of source base station forwarding within the scope of the duration of end mark timer time, show that source base station has not had forwarding data to be sent to target BS, determine and all forwarding datas of buffer memory are sent to after subscriber equipment at target BS, start to send new data; Or in the time that described end mark timer is not then also received the end mark message of source base station transmission, think that source base station has not had forwarding data to be sent to target BS, determine and all forwarding datas of buffer memory are sent to after subscriber equipment at target BS, start to send new data.Wherein, target BS is receiving after forwarding data, starts end mark timer and refers to as long as before starting to forward new data, as long as receive the forwarding data that comes from source base station, just starts (or renewal) timer.If target BS has started to send new data, then receive after the forwarding data of source base station transmission, can abandon the forwarding data receiving.

Therefore, the duration how end mark timer is reasonably set is a problem demanding prompt solution, if the duration arranging is long, there will be the problem that in handoff procedure, data transmission rate reduces or interrupts, if the duration arranging is too short, can make to start to send new data time, forwarding data also arrive target BS completely, target BS is abandoned and start to send the forwarding data of just receiving after new data.
