Embodiment Construction

[0048] Hereinafter, the implementation of the processing method and apparatus for cell handover in the embodiment of the present invention will be described in detail in conjunction with the accompanying drawings.

[0049] figure 2 It is a schematic flowchart of a processing method in a cell handover according to an embodiment of the present invention, such as figure 2 shown, including:

[0050]Step 201: When the terminal determines to perform cell handover, it performs a random access process with a new access cell that needs to be accessed;

[0051] Step 202: During the random access process, the terminal starts to receive system information of the newly accessed cell, so as to obtain the SFN of the newly accessed cell.

[0052] exist figure 2 In the processing method in the cell handover shown, the terminal starts to receive the system information of the newly accessed cell during the random access process with the newly accessed cell, so as to obtain the SFN of the n...

Abstract

The invention discloses a processing method and device during cell switching. The method comprises the steps of executing a random access process between a terminal and a new access cell needed to be accessed by the terminal while the cell switching is determined to be carried out; and beginning to receive a system message of the new access cell by the terminal in a random access process so as to obtain an SFN (Single Frequency Network) of the new access cell. According to the method and the device disclosed by the invention, the interruption time length of uplink data transmission of the terminal in the cell switching process can be reduced.

Description

technical field [0001] The present invention relates to cell switching technology, in particular to a processing method and device in cell switching. Background technique [0002] In the 3GPP Long Term Evolution (LTE) 36.331v870 protocol, the operations that the terminal needs to perform during cell handover are given: the terminal first performs downlink synchronization in the new cell to be accessed, then re-establishes the radio bearer (RadioBearer, RB), and The system configuration parameters contained in the resource control protocol connection reconfiguration (RRC connection reconfiguration) message, the system is configured to the bottom layer, and after the random access is completed, the system configuration that is not related to the system frame number (SFN) of the new cell is enabled, and the system related to the SFN The configuration can only be enabled after the terminal obtains the SFN. [0003] Specifically, the process of cell handover by a terminal in an ...
