[0008] For this reason, in the prior art, there are two expansion methods, one is to split the cell on the basis of the existing network, add more base stations, and use the same frequency points as the existing network. Operators need to pay more investment, frequency resources are still not effectively used, the return on investment is low, and the construction period of new base stations is long, making it difficult to obtain sites; the second is to rebuild an overlay network on the basis of the existing network

The disclosed building method for business channel in cross frequency-band network comprises: selecting target carrier frequency for MS in available frequency resource center combined overlapped sub-frequency-band; controlling MS to build business channel in target carrier frequency. It also discloses the relative devices, such as BSS and MS. This invention supports system capacity as five even six carrier frequency, and applies resource more effectively.
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: [0004] Band identification (Block Designator) Sub-band (Band Subclass) Transm...
