Embodiment Construction

[0021] In the description of the embodiments below, reference is made to the accompanying drawings, which form a part hereof, and in which embodiments of the invention may be implemented, for example in the fields of DVB-H, TPS bit information and OSI layer 1 signaling. provide one or more improvements. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope of the present invention.

[0022] The standard document EN 300 744 V1.5.1 (2004-06) published by the European Telecommunications Standards Institute (ETSI) specifies a TPS carrier signal for signaling parameters about the transmission scheme used. The TPS carrier signal is formed at the physical layer or OSI layer 1 of the communication protocol stack. Decoding of the TPS in the receiver makes it possible to determine the channel coding and modulation used in the transmission, and this information is used to control the receive...

Abstract

Methods and system for transmitting a DVB-H network ID in transmission parameter signaling (TPS) data are described. A sixteen bit DVB-H network ID may be divided into four four-bit portions, and each four-bit portion may be included in an orthogonal frequency division multiplex (OFDM) TPS frame transmitted by the DVB-H network. Because each OFDM TPS frame also includes a frame order of that frame within its corresponding super-frame, a receiver of the TPS data can reassemble the network ID by ordering the four received portions according to the frame order of the respective OFDM TPS frames in which they were received. The sixteen bit DVB-H network ID may alternatively be divided into two eight-bit portions, and each eight-bit portion may be included in the cell_ID bits of two frames of a super-frame.

Description

technical field [0001] The present invention generally relates to mobile telecommunication networks and systems. More specifically, the present invention relates to the transmission of parameter information in mobile telecommunication networks and the inclusion of network IDs in transmission parameter signaling (TPS) data bits. Background technique [0002] Digital broadcasting systems such as the various DVB-T (Digital Video Broadcasting Terrestrial) and DAB (Digital Audio Broadcasting) systems, ATSC, ISDB and other similar broadcasting systems consider a transmitter system configured in a cellular manner, enabling The transmitter site is selected to receive a signal of suitable quality over the geographic area. This cellular nature of transmitter coverage enables mobile receivers to achieve satisfactory performance even while moving. Efforts are being made to incorporate DVB receivers into mobile phones and personal digital assistants (PDAs), for which no DVB standard wa...
