Problems solved by technology

This cannot always be satisfied in real networks
Moreover, during the entire blind handover process, the terminal and the system do not know the frequency quality estimation of the target cell, and it is easy to cause call drop.

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The core idea of ​​the present invention is to control the cycle of starting the compression mode for measurement, avoid frequent and periodic use of the compression mode, and improve the success rate of switching in combination with blind switching. Please refer to figure 1 , this embodiment specifically includes the following steps:

[0027] Step 101: Initialize, set R to 0, S to {v, v}, and Stemp to {v, v}, wherein R represents the number of times that the cell signal set of the measurement result is continuously consistent during each compressed mode measurement, and the cell signal Set consistency means that each element representing a cell in the cell signal set is the same; S and Stemp represent the cell signal set obtained by each measurement, S represents a formal record, and Stemp represents a temporary record. For s...

Abstract

This invention discloses an applied method for an optimized compression mode including: combining the compression mode measurement with a blind switch to compare the times of continuous uniformity of different frequencies or different system areas and a pre-set threshold value to control the period of the start compression mode to reduce the frequency and time used by the mode, further more, this invention determines the time scale for a user starting the compression mode for the first time by judging if any user starts the mode at the present with a certain time interval to stagger the time for starting the compression mode by multiple users .

Description

technical field [0001] The invention relates to different-frequency or different-system measurement technology in a mobile communication system, in particular to a compressed mode measurement method in a Code Division Multiple Access (CDMA, Code Division Multiple Access) system. Background technique [0002] In a mobile communication system, a mobile terminal often needs to move from one cell to another, and the operation from one cell to an adjacent cell in a call state is called handover. In the CDMA system, the handover between cells of the same frequency can be soft handover, and the handover success rate is very high, while the handover between cells of different frequencies or between cells of different systems can only be hard handover. Since the CDMA system adopts code division multiple access technology, different cells use the same frequency and rely on different spreading codes to distinguish each other. The CDMA system adopts a continuous transmission and recepti...
