Embodiment Construction

[0026] In order to further explain the technical means and effects of the present invention to achieve the intended purpose, the method for reading cell system information by the WCDMA mobile phone proposed by the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] In the specific embodiment of the present invention, such as figure 2 As shown, when a WCDMA mobile phone performs cell selection or reselection after it is turned on, the specific steps for reading system messages are as follows:

[0028] Step 1: Establish a BCH channel and enable BCH data receiving processing.

[0029] Step 2, decode the main system information block of the cell from the fixed radio frame position according to the communication protocol, and report to the upper layer protocol entity, and the upper layer protocol entity obtains the scheduling information of the system information block from the main system information blo...

Abstract

The invention discloses a method for WCDMA cell phone reading the subdistrict system messages. The technical solution of the invention is following: the method for WCDMA cell phone reading the subdistrict system messages comprises the specific steps: step one, building a BCH signal channel and opening the BCH receiving process; step two, decoding the main system message block of the subdistrict from the fixed radio frame position and reporting to the superior protocol entity; the superior protocol entity obtains the scheduling information according to the situation and the physical layer closes the BCH receiving process; step three, confirming the starting time on the time axis of the system message needed to be read according to the system message scheduling; the physical layer opens theBCH receiving process in the starting time. The technical solution of the invention shortens the time of reading the system message in the process of subdistrict selection and re-selection, and reduces the consumption of the electrical quantity of the limited cell phone battery.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for a mobile phone to read cell system information. Background technique [0002] After the WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) mobile phone is turned on, it must first go through the network search process, search for a suitable WCDMA cell, and then camp in this cell before starting to use the mobile network provided by the mobile operator. Internet service. In the process of camping in this cell, it is necessary to read the system information of the cell. Only by obtaining a complete set of cell system information can the WCDMA mobile phone normally use the wireless resources provided by the cell. [0003] The cell system information in the WCDMA network includes a master system information block MIB (Master InformationbLock), a scheduling block SB (Scheduling Block), and other system information blocks SIB (Syst...
