Embodiment Construction

[0033]The processing of the download and its package index number configuration are explained below. This section is organized as follows: First, cell-packet broadcasting using traffic cycling is explained. With the introduction of the concept of download communication classification, the concept of download status can be established, and a general idea for indicating the status of software download is given. Interaction is established between broadcast and dedicated resources in order to complete the download on all terminals involved with reference to the download probability ending in a single cell. According to a proposed protocol for handling segment downloads, some new information elements are introduced to be exchanged by the network and the terminal. Furthermore, a new termination state (Download state) is introduced, which completes the familiar idle and connected modes eg in 3GPP (3rd Generation Partnership Project). It also outlines some other alternative protocol...

Abstract

According to one aspect of the invention, in a radio communications system comprising at least one base station (BS1, BS2) provided with means for transmitting data via a communication link (BCCH; V), wherein the data is divided into a plurality of data packets and being transmitted via the communication link to at least one receiving station (UE). To reduce power consumption it is proposed that the downloading of the data packets is halted if it is determined that a data packet has not been received or a corrupted data packet has been received by the receiving station, the missing or corrupted data packet is retransmitted via the same or a different communication link at a later time.

Description

technical field [0001] The present invention describes a method for downloading software data in a radio communication system, in particular a cellular network using broadcast or vehicle services, and a radio communication system. Background technique [0002] A radio communication system transmits data or information, in particular voice, picture information or other data, via electromagnetic waves between a base station and user equipment (mobile phone or terminal). Commonly known communication systems are mobile telecommunication systems like UMTS (Universal Mobile Telecommunications System) or wireless data networks like HiperLAN. [0003] In such communication systems, data transmission may be on the one hand using one or more broadcast channels for point-to-multipoint communication links, or on the other hand, using one or more broadcast channels for point-to-point communication links a dedicated channel. Information received by multiple or all user equipments may be...
