Embodiment Construction
[0028] Such as figure 1 , the basic process of the present invention comprises the following steps:
[0029] The first step is to determine the number of existing sites that can be used through on-the-spot surveys. Due to the limitations of funds and the inability to build sites in some special areas, the maximum number of new sites can be established, so as to determine the maximum number of sites that can be provided in the area; when the continuous coverage of the business is satisfied, the UMTS900MHz carrying ratio Using UMTS2000MHz to bear the weight can reduce the number of stations.
[0030] The second step is to divide the area into hotspot areas and general areas according to the business focus and predict the traffic volume of each; and determine the initial number of frequency points, generally initially set to single carrier frequency;
[0031] In the third step, the hotspot area is carried by UMTS2000MHz, and the general area is carried by UMTS900MHz. According t...

The present invention relates to a common net-linking method for 900MHz and 2000MHz frequency section in the mobile communication system to confirm the maximum sites. When the method satisfies the service continuous covering, the UMTS900 can reduce the sits les than the UMTS2000; the area is divided into hot area and the regular area according to the service point and anticipates the conversation quantity of the regular area; and confirming the initial frequency sites; the hot area is supported by the UMTS2000; the regular area is supported by the UMTS900, estimating the total site quantity according to the scale; adjusting the area frequency section, carrying frequency quantity in the area until the total site quantity is less than or equal to the limit of the providing site quantity. The invention rationally processes the net linkage for UMTS900 and UMTS2000, combining the characteristics, suitable service of the two frequency sections; the invention considers the practically available site resources and the frequency resource limit, which makes the net-linkage simple and quick via guiding the dynamic feedback adjusting mechanism.
Description
technical field [0001] The invention relates to a networking method for introducing UMTS900MHz and UMTS2000MHz frequency bands into the existing GSM900MHz network in the third generation mobile communication 3G (WCDMA, TD-SCDMA, CDMA 20001X) system. Background technique [0002] The 3GPP protocol standard has undergone a series of evolutions of Release99, Release4, Release5, Release6 and the current Release7. In the initial stage, 3GPP assigned to 3G the frequency point of 2000MHz frequency band. In the Release7 version, the 900MHz frequency band was allocated for 3G use. [0003] Compared with UMTS2000MHz, UMTS900MHz has lower wireless propagation path loss and larger coverage. Under the premise of providing the same service and coverage, UMTS900MHz consumes fewer base stations than UMTS2000MHz, which can be used to reduce UMTS operating costs and end-user usage costs. UMTS900MHz can solve the problem of insufficient coverage of UMTS2000MHz in remote areas such as suburb...
