Embodiment 1

[0053] figure 2 It is a flowchart of establishing a demand list of system information data blocks in an embodiment of the present invention.

[0054] First, please refer to figure 2 , Step S121 is executed to receive the main scheduling information data block from the public broadcast channel. It should be noted that the main scheduling information data block includes the identifier of the system information data block to be sent by the target base station. Therefore, the subsequent terminal may determine the system information data block demand list according to the main scheduling information data block.

[0055] Next, continue to refer figure 2 Execute step S122 to determine whether the received main scheduling information data block has been received.

[0056] It should be noted that the base station of the target cell periodically sends the main scheduling information data block. In an embodiment of the present invention, the terminal may save the reception record of the li...

Embodiment 2

[0068] image 3 It is a flowchart of establishing a demand list of system information data blocks in another embodiment of the present invention.

[0069] First, please refer to image 3 , Step S121 is executed to receive the main scheduling information data block from the public broadcast channel.

[0070] It should be noted that the main scheduling information data block includes the identifier of the system information data block to be sent by the target base station. Therefore, the subsequent terminal can receive the system information data block sent by the target base station according to the main scheduling information data block.

[0071] Next, continue to refer image 3 Execute step S122 to determine whether the received main scheduling information data block has been received.

[0072] As mentioned above, since the base station of the target cell periodically sends the main scheduling information data block, in the embodiment of the present invention, the terminal can avoid ...

Abstract

The present invention provides a method and device for receiving a system information data block and a cell reselection method. The method for receiving the system information data block includes: accessing a public broadcast channel of a base station of a target cell; The data block requirement list selectively receives the system information data block of the target cell base station. The method for receiving the system information data blocks reduces the number of system information data blocks received, thereby reducing the receiving time of the system information data blocks and improving the network scheduling efficiency.

Description

Technical field [0001] The present invention relates to the technical field of cell reselection by a mobile terminal in a wireless communication system, in particular to a method and device for receiving system information data blocks and a cell reselection method. Background technique [0002] In the current third-generation wireless communication system, the system information data block defines various types of public information provided by the current cell. It can be said that the system information data block is the most basic reference for mobile terminals to access the network. Therefore, multiple processes such as cell selection, cell reselection, and network search need to be judged based on system information data blocks, such as judging whether the current cell is suitable for camping, and judging whether the target neighboring cell is suitable for reselection. [0003] However, there are many types of system information data blocks, and due to network coverage, system ...
