Embodiment Construction

[0047] Embodiments 1 and 2 of the present invention provide a method for cell measurement, which includes: scanning frequency points; judging whether the scanned frequency points meet the preset measurement conditions, and if so, identifying the frequency point corresponding to the frequency point A cell, measuring the signal level of the cell. By adopting the technical solution provided by the embodiment of the present invention, the number of cells measured by the UE can be limited, and the heavy work of measuring too many cells by the UE is avoided.

[0048] refer to figure 1 , Embodiment 1 of the present invention provides a method for cell measurement, the method comprising:

[0049] Step 101, the network side presets that the UE can measure up to N cells;

[0050] The N cells in this step are values ​​determined by the operator based on experience and set on the network side.

[0051] In step 102, the UE scans the frequency points supported by the access technology ac...

Abstract

The invention discloses a method of measuring cells, comprising: scanning frequency point; judging whether the signal level of the scanned frequency point satisfies the preset measuring condition; if so, identifying the cell corresponding to the frequency point, measuring the signal level of the cell. Using the technical proposal provided by the invention is able to limit the number of the cells measured by UE and avoid the heavy work of measuring the signal levels of multiple cells.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for measuring and reading a control channel in a cell and user equipment. Background technique [0002] After camping on the network, user equipment (UE, User Equipment) continuously monitors neighboring cells, and identifies and measures detected neighboring cells. The UE can also read the offset of the identified cell through a control channel (broadcast control channel, MBMS control channel). According to the measurement results and offsets of neighboring cells, the identified cells are sorted, and the cell with the highest ranking is used as the reselected cell. Wherein, the measurement result may be: measurement intensity, measurement quality and interference intensity. Wherein, the offset of a cell includes: an offset of an individual cell, a 1-to-1 offset between cells, and an offset for a preferred frequency layer of a Multimedia Broadcast Multicast Serv...
