Problems solved by technology

[0006] However, Option 1 cannot completely solve this problem, because with the increase of frequency band definitions, the terminal cannot support all the frequency bands defined by 3GPP; and Option 2 requires a thorough network transformation, because whether the terminal can access depends on For broadcast messages on the network side, the base station needs to be modified
Even if the terminal supports this technology, it still cannot access normally under the base station network that does not support this technology

Abstract

The invention discloses an access attempt method of a terminal. The access attempt method comprises the following steps: acquiring a frequency band range supported by the terminal; acquiring an E-UTRA absolute radio frequency channel number (EARFCN) of a cell; converting the EARFCN of the cell into actual frequency information when the EARFCN of the cell is not matched with the EARFCN supported by the terminal; and determining that the terminal can perform a subsequent access operation when the actual frequency information falls into the frequency band range supported by the terminal. The invention also discloses a terminal and an access attempt device thereof at the same time.

Description

Technical field [0001] The present invention relates to the field of Long Term Evolution (LTE) systems, in particular to a terminal and an access attempt method and device thereof. Background technique [0002] At present, the LTE frequency bands specified in the 3GPP standard are relatively scattered, ranging from several hundred MHz to 3.5 GHz. The deployment of frequency bands for the LTE system is not uniform in various countries and regions. In the prescribed division of multiple frequency bands, there are cases where the same frequency spectrum is divided into multiple overlapping spectrums. For example, the Band41 (2496-2690MHz) frequency band of TD-LTE completely includes the Band38 (2570-2620MHz) frequency band of TD-LTE. For the overlapping spectrum part, different countries and regions use different frequency band numbers, that is, when the terminal searches the network, The same frequency band will be translated into different long-term evolution radio access network...
