Problems solved by technology

[0023] However, the above method also has problems in practical applications: if the terminal is prohibited from performing cell reselection, then when the signal quality of the serving cell decreases or even does not meet the camping conditions, the terminal will be disconnected from the network, thereby reducing user experience. The processing method is to guide t

Example Embodiment

[0040] In view of the problems in the prior art, the present invention proposes a brand-new cell reselection scheme, which can improve user experience.

[0041] In order to make the technical scheme of the present invention clearer and more comprehensible, the scheme of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0042] figure 2 It is a flowchart of a method embodiment of the present invention. Such as figure 2 As shown, including the following steps:

[0043] Step 21: Determine whether the terminal X is in the ping-pong reselection area, if yes, perform step 22, otherwise, repeat step 21.

[0044] In this step, any of the following methods 1) to 3) can be used to determine whether the terminal X is in the ping-pong reselection area.

[0045] 1) Cell ID positioning technology:

[0046] It is determined whether the number of changes of the ID of the serving cell of terminal X within a predetermined period of time is ...

Abstract

The invention discloses a reselection method for a cell. The method comprises the following steps of: A, confirming a terminal X whether is in a ping-pong reselection region or not, if so, executing a procedure B; B, measuring specified parameters of a service cell per se by the terminal X, and confirming a new starting measurement threshold according to a measuring result; C, carrying out a reselection for the cell according to the new starting measurement threshold. Meanwhile, the invention discloses a reselection device for the cell. The method and the device disclosed by the invention are applied, therefore, user experience can be promoted.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a cell reselection method and terminal. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) international standard, the cell reselection process of a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system in the idle (Idle) state can be divided into three sub-processes (assumed to be intra-system reselection selection), that is, the start-up sub-process, the judgment sub-process and the re-selection sub-process. The following three sub-processes are introduced in detail respectively. [0003] 1) Start test sub-process [0004] In the Idle state, when a predetermined condition is met, the terminal will start the measurement of all neighboring cells. [0005] Specifically, when the cell where the terminal is located, that is, the serving cell of the terminal is prohibited, the terminal will start the measurement of all adjace...
