Embodiment 1

[0033] see figure 1 The method for avoiding cell ping-pong reselection provided by Embodiment 1 of the present invention includes:

[0034] 101. Select a cell that can be used as a candidate serving cell from the current serving cell and adjacent non-serving cells according to the S criterion. The S criterion is that the signal strength and signal quality are greater than or equal to the minimum service threshold of the serving cell;

[0035] Signal strength S minimum and signal quality S minimum are the minimum service thresholds to meet the serving cell

[0036] The S criterion includes that the signal strength S value of the cell is greater than or equal to the signal strength S minimum value of the serving cell, and the signal quality S value of the cell is greater than or equal to the signal quality S minimum value of the serving cell; only the current serving cell and the adjacent cell Only when the signal strength S value and the signal quality S value are greater than...

Abstract

A method for avoiding cell pingpong reselection is disclosed in the present invention, which comprises: cells which are able to be candidate serving cells are selected, according to an S criteria, from current serving cells and adjacent non-serving cells; an optimal cell is determined, according to an R criteria, from the candidate serving cells; if the optimal cell is not the current serving cell, it is determined that whether the signal intensity and the signal quality of the optimal cell are greater than or equal to reselection thresholds, wherein the reselection thresholds are greater than the minimum serving thresholds of the serving cell; and in the condition that the signal intensity and the signal quality of the optimal cell are greater than or equal to reselection thresholds, the cell reselection is initiated. The embodiments of the present invention also provide a corresponding terminal. Since the reselection thresholds of the cell reselection are increased in the solution of the present invention, the cells with good signal intensity and bad signal quality or the cells with bad signal intensity and good signal quality will not be within the candidate range of the reselection cells, and thus the cell pingpong reselection is avoided to occur frequently effectively.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a terminal for avoiding cell ping-pong reselection. Background technique [0002] Compared with traditional voice services, today's mobile communication systems can provide more abundant service types. In particular, the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), as a third-generation mobile communication system, uses Wideband Code Division Multiple Access (WCDMA, Wideband Code) on the basis of the GSM system. DivisionMultiple Access), which can provide packet-based text, digital voice, video and multimedia data services for mobile phone and computer end users around the world at a rate greater than 21Mbps. [0003] The UMTS system includes a core network (CN, Core Network) and multiple radio network subsystems (RNS, Radio Network Subsystem). The RNS constitutes a UMTS terrestrial radio access network (UTRA...
