Embodiment 1

[0048] like figure 2 As shown, it is a schematic flowchart of a method for a communication terminal receiving system information in this embodiment, including:

[0049] Step S10: BCH completes the configuration. When the communication terminal switches from one application state to another, the configuration of the BCH will change. The system information is sent to the communication terminal in the BCH, so when receiving the system information, the configuration of the BCH should be completed first, such as sending time slots, sending formats, and so on. The specific configuration process is well known to those skilled in the art and will not be repeated here. Then step S11 is executed.

[0050] Step S11: Obtain the communication terminal's requirements for system information in the current application state. The system information specified in the 3GPP standard is shown in Table 1. For different communication modes, what system information needs to be used is specified ...

Embodiment 2

[0078] Compared with Embodiment 1, the difference of this embodiment lies in the specific execution process of step S12. like Figure 4 As shown, it is the execution process of step S12 of this embodiment, including:

[0079] Step S1211: Create a scheduling information table.

[0080] Step S1212: Determine whether the current system information is the system information to be received. It has been explained above that the system information sent continuously and cyclically in the broadcast channel includes not only the system information required by the communication terminal in the current application state, but also the system information not required by the communication terminal in the current application state. During the sending time period of this unnecessary system information, the communication terminal can receive it, so as to save power consumption. Or, further, some other operations may be performed during the sending time of the system information that does not...

Abstract

The present invention provides a communication terminal and a method and device thereof for receiving system information. The method for receiving system information of the communication terminal comprises: after completing configuration of a broadcasting channel, acquiring corresponding scheduling information according to the demand of the communication terminal for system information under present application state; and receiving relative desired system information based on the scheduling information. The technical solutions of the present invention can improve the efficiency of the communication terminal for receiving system information, save software and hardware resources for the communication terminal and reduce power consumption during the receiving process.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication terminal and a method and device for receiving system information thereof. Background technique [0002] In the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), after the communication terminal is turned on, it first performs a cell search, and when it finds a suitable cell, it starts to read the broadcast channel (BCH, Broadcast Channel) of the cell. To obtain corresponding system information, such as parameters related to public channels, location areas, cell selection, and cell reselection. According to these parameters, the communication terminal can establish a connection with the base station and complete the communication. Therefore, the reception of system information is a key factor affecting the performance of the communication terminal. [0003] System information can be divided into differen...
