Title (EN) METHOD AND DEVICE FOR KEEPING CONTINUITY OF UDC FUNCTION
(FR) PROCÉDÉ ET DISPOSITIF DE MAINTIEN DE LA CONTINUITÉ D'UNE FONCTION UDC
(ZH) 一种保持UDC功能连续性的方法及设备
Abstract:
(EN) The embodiments of the present invention relate to the technical field of wireless communications, especially to a method and device for keeping the continuity of a UDC function, for solving the problem in the prior art that a target base station cannot correctly decompress uplink compressed data sent by a terminal when the terminal switches from a source base station to the target base station. A first base station sends a switching request message to a second base station, and sends, to the terminal, received UDC relevant information about the second base station returned by the second base station, so that the terminal performs, after switching to the second base station, data compression processing using a compression mode determined by the UDC relevant information about the second base station. Thereby, the negotiation of a compression mode between a terminal and a second base station after switching is realized, and the second base station can accurately decompress uplink compressed data sent by the terminal after the terminal switches to the second base station.
(FR) Les modes de réalisation de la présente invention concernent le domaine technique des communications sans fil, notamment un procédé et un dispositif de maintien de la continuité d'une fonction de compression de données de liaison montante (UDC), afin de résoudre le problème de l'état de la technique selon lequel une station de base cible ne peut pas décompresser correctement des données compressées de liaison montante envoyées par un terminal lorsque le terminal commute d'une station de base source à la station de base cible. Une première station de base envoie un message de demande de commutation à une seconde station de base, et envoie, au terminal, des informations pertinentes d'UDC reçues, concernant la seconde station de base, renvoyées par la seconde station de base, de sorte que le terminal effectue, après commutation sur la seconde station de base, un traitement de compression de données à l'aide d'un mode de compression déterminé par les informations pertinentes d'UDC concernant la seconde station de base. Ainsi, la négociation d'un mode de compression entre un terminal et une seconde station de base, après commutation, est réalisée, et la seconde station de base peut décompresser avec précision les données compressées de liaison montante envoyées par le terminal après commutation du terminal sur la seconde station de base.
(ZH) 本发明实施例涉及无线通信技术领域,特别涉及一种保持UDC功能连续性的方法及设备,用以解决现有技术中的终端由源基站切换到目标基站时,目标基站无法正确解压终端发送的上行压缩数据的问题。第一基站向第二基站发送切换请求消息;将接收到的所述第二基站返回的所述第二基站的UDC相关信息发送给所述终端,以使所述终端在切换到所述第二基站后采用由所述第二基站的UDC相关信息确定的压缩方式进行数据压缩处理。从而实现在切换后终端与第二基站的压缩方式的协商,在终端切换到第二基站后,第二基站可以准确地对终端发送的上行压缩数据进行解压。
