Embodiment Construction

[0023] Reference will now be made in detail to the preferred embodiments of the invention which are illustrated in the accompanying drawings. The device and method for scanning intelligent WCDMA channels in the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. For conciseness, detailed descriptions of well-known structural functions will be omitted.

[0024] Fig. 1 is a structural diagram of a device for scanning smart WCDMA channels. The device for scanning smart WCDMA channels includes a baseband unit 100 , a list unit 120 , a control unit 110 and a radio frequency unit 130 .

[0025] The baseband unit 100 processes baseband signals transmitted or received through the mobile communication terminal. Baseband signals, such as voice, character, symbol or image signals.

[0026] The listing unit 120 provides a listing of channels assigned to the WCDMA system. Each channel is a communication channel for tra...

Abstract

The present invention provides for scanning a channel of a mobile communication system for determining availability to transmit or receive a signal. The scanning of channels is based on priority. The priority for occupying is determined by availability of a frequency group (with a frequency band) and / or an occupation number of a channel (corresponding to availability to utilize the channel).

Description

technical field [0001] The present invention relates to a mobile communication system, in particular to a device and method for scanning mobile communication channels such as intelligent wideband code division multiple access (WCDMA) channels, so that mobile terminals can scan the best channel in the mobile communication network. Background technique [0002] Many countries have adopted mobile communication systems such as Wideband Code Division Multiple Access (WCDMA) networks for multimedia data transmission. Compared with other communication systems, WCDMA networks can provide high-quality image services and high data rates. [0003] Mobile terminals in the WCDMA network make calls or use data services through the channel (or frequency) allocated by the base station in the corresponding area. Manufacturers of mobile terminals use various methods to increase the scanning efficiency of assigned channels. One method of increasing scanning efficiency includes scanning a spe...
