Abstract
Description
technical field
[0001] The invention relates to mobile communication technology, in particular to a method, system and device for establishing a service channel in a cross-frequency band networking. Background technique
[0002] In the prior art, since the transceiver duplex interval between the 450MHz frequency band system and the mobile station (MS) is only 10M, in order to meet the requirements of MS RF front-end transceiver isolation, the RF front-end filter bandwidth of the MS is generally only 5M. Therefore, in terms of MS , the CDMA system with the largest configuration that can be realized by using a single sub-frequency band is a four-carrier frequency system, that is, the MS can work normally within four carrier frequency ranges.
[0003] According to the agreement, the 450MHz frequency band is divided into 8 sub-frequency bands from A to H, as shown in Table 1:
