Method and device for inter-frequency adjacent cell measurement

Abstract

The invention discloses a pilot frequency neighborhood measuring method and a device, wherein the method comprises that: when the result obtained by dividing measuring periods Tmeasure GSM of 2G neighborhoods by the measuring intervals Tmeasure NTDD of 3G neighborhoods in all pilot frequencies is smaller than the frequency point sum Ncarrier of the current service cell and the neighborhood, the 3G neighborhoods in all pilot frequencies in the current service cell are measured in the measuring periods Tmeasure GSM of the 2G neighborhoods. The device comprises a measuring recognition module and a measuring module. By utilizing the invention, the communication state in the neighborhoods in pilot frequencies can be measured timely, unnecessary intersystem reselection can be avoided, and the communication quality can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for measuring inter-frequency adjacent cells. Background technique [0002] In practical applications of TD / GSM dual-mode mobile terminals, it often appears that the mobile terminal shows that there is no network, or is in the network search, or is in the middle of the paging state, and the communication quality is poor. The reason for the above phenomenon is that the mobile terminal frequently performs cell reselection between the 3G network and the 2G network, for example, reselects from a 3G cell to a 2G cell, or reselects from a 2G cell to a 3G cell. Reselection between networks will bring a reselection delay of 6-8 seconds. During this reselection delay, the mobile terminal is in an unreachable state, that is, the mobile terminal cannot be paged by the network side, and the above-mentioned error occurs on the mobile terminal side.

Problems solved by technology

[0027] To sum up, it can be seen that whether a dual-mode mobile terminal selects a cell for reselection is reasonable or not depends on whether the measurement of communication parameters of neighboring cells is timely and accurate. The measurement results cannot reflect the current actual communication status of each neighboring cell, which will lead to inaccurate selection of reselected cells, and in many cases will cause unnecessary inter-system cell reselection operations, resulting in decreased accuracy of cell reselection and affecting communication quality
