Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0063] The present invention provides a method for reordering data sent by a base station by a wireless network controller. The main idea is: the RNC calculates the initial sending time of each data by using the frame number information and sending times contained in the data, and according to each Reorder the data according to the order of the time when the data is first sent. In this way, the UE does not need to add a TSN in the MAC-es PDU data field, thereby saving air interface resources.

[0064] A preferred embodiment is given below to describe in detail.

[0065] see image 3 , image 3 It is a flow chart of the RNC reordering the data received from the NodeB in a preferred embodiment of the present invention. The process includes the followi...

Abstract

This invention discloses a method for re-arranging data sent by the base station by a radio network controller (RNC) including the following steps: A, the RNC receives data sent by Node B and computes the initial sending time of the data based on the data content, B, the RNC re-arranges the data received this time and the buffer-stored data according to the initial sending time of the data and the initial sending time of buffer-stored data, C, returning to step A to receive the next data.

Description

technical field [0001] The present invention relates to a technique for processing data sent by a base station (NodeB) by a radio network controller (RNC) in a wideband code division multiple access (WCDMA) system, and in particular to a radio network controller that reorders data sent by a base station Methods. Background technique [0002] In the WCDMA REL-6 system, RNC may receive data received from user equipment (UE) sent from different NodeBs. Although the air interface (Uu interface) between NodeB and UE should be synchronized, the data received from Uu interface The data may be out of order, and the Iub interface between the RNC and the NodeB may also experience delay and jitter, so that the time for data sent by different NodeBs to reach the RNC is different, resulting in confusion in the order of user data received by the RNC. [0003] In case of out-of-order, RCN needs to reorder the data received from NodeB. In order to complete the reordering function, the 3GP...
