Abstract

The embodiment of the invention discloses a cell selection method and device and terminal equipment. The method comprises the steps of receiving a release message sent by network-side equipment, wherein the release message carries at least one piece of frequency point information; initiating a random access request to a target cell in multiple cells corresponding to the at least one piece of frequency point information, and receiving congestion feedback; and updating channel parameters of the target cell, and selecting a cell based on the updated channel parameters. The method of the embodiment of the invention solves a problem of terminal access rejection caused by possible service congestion at the network side due to a circumstance that many users request the access to the same cell with the best signals in the prior art.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a cell selection method, device and terminal equipment. Background technique [0002] When the network releases the frequency point information carried in the release message, it does not specify the relevant parameters of the network cell, such as psc (primary scrambling code, scrambling code information), etc. The terminal may find multiple cells with the same frequency in the area, and then In these cells, the terminal will choose the best cell. At present, major chip manufacturers will use RSCP (received signal code power or signal strength) or ECNO (signal quality) to select the cell with the best signal strength or signal quality. There is no Consider the actual traffic load of the cell. [0003] However, users in this area may search the network after receiving the frequency points issued by the network when performing voice services...
