Embodiment 1

[0053] figure 2 It is a flow chart of establishing a system information data block requirement list in an embodiment of the present invention.

[0054] First, please refer to figure 2 , execute step S121, receive the main scheduling information data block from the public broadcast channel. It should be noted that the master 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 determine the system information data block requirement list according to the master scheduling information data block.

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

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

Embodiment 2

[0068] image 3 It is a flow chart of establishing a system information data block requirement list in another embodiment of the present invention.

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

[0070] It should be noted that the master 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 master scheduling information data block.

[0071] Next, continue to refer to image 3 , execute step S122 to determine whether the received master 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 ...

Abstract

The invention provides a method and device for receiving system information data blocks and a cell reselection method. The method for receiving the system information data blocks comprises the steps that access to a public broadcast channel of a target cell base station is obtained; according to a system information data block demand list of a terminal, the system information data blocks of the target cell base station are selectively received. According to the method for receiving the system information data blocks, the receiving number of the system information data blocks is reduced, so that the receiving time of the system information data blocks is shortened, and the network scheduling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cell reselection performed 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 all kinds 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 according to the system information data block, for example, judging whether the current cell is suitable for camping, judging whether the target neighboring cell is suitable for reselection, etc. [0003] However, there are many types of system information data blocks, and due to network...
