Problems solved by technology

[0004] The mobile multimedia broadcasting network adopts a one-way communication method, that is, from the transmitter system to the mobile receiving system, the mobile communication network can be used in the reverse direction to complete functions such as authentication and on-demand broadcasting, so the mobile multimedia broadcasting front-end system cannot switch and control the terminal in real time. As a result, the switching operation is completed independently by the terminal, that is, one-way communication switching

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] Figure 1 is a schematic diagram of a mobile multimedia broadcasting network. User terminals move in the three network areas A, B, and C, and they are neighbor networks.

[0028] The mobile multimedia broadcasting terminal in network A listens to networks B and C according to the adjacent network information, which is planned and configured by the mobile multimedia broadcasting front-end system, and sent to the terminal by the transmitter through the air interface. Table 1 describes the information of the adjacent cell network, where the adjacent cell network information includes the number of adjacent cell networks, the level of the adjacent cell network, the number of the adjacent cell network, the frequency point number of the basic carrier frequency of the adjacent cell, the center frequency, and the bandwidth information. Listen to...

Abstract

This invention relates to money switch and judgment method of multi-media broadcast receive terminal, which comprises the following steps: a, terminal receives neighbor network information from mobile multi-media broadcast front end system; b, terminal computes the data sampling for error codes and if error code rate is larger than error rate gate, then judging the data as error for executing step c, otherwise for step b; c, terminal computes error rate and judging whether the rate proportion is super error rate gate; if yes, then terminal monitors near signal channel into step d; otherwise in step b; d, terminal comparing received network with near each network signal quality.

Description

technical field [0001] The invention relates to the field of digital mobile communication, in particular to a handover judgment method of a mobile multimedia broadcasting terminal. Background technique [0002] In recent years, digital mobile multimedia broadcasting technology and standards have developed rapidly, such as DVB-H (Digital Video Broadcasting Handheld Receiver: Digital Video Broadcast Handheld) in Europe, MediaFLO (Media Single Forward Link: Media Forward Link Only) in the United States and China's CMMB (China Mobile Multimedia Broadcasting: China Mobile Multimedia Broadcasting), etc., all use OFDM (Orthogonal Frequency Division Multiplexing: Othogonal Frequency Division Multiplexing) modulation technology. In order to save terminal power consumption, they all use time-division transmission and reception. , that is, in the time domain, the multimedia data information of each broadcast service is concentrated and continuously modulated on multiple OFDM symbols, a...
