Embodiment Construction

[0026] In order to avoid interference from the mountain station to the ground station, the present invention allocates different carrier frequencies to the mountain station and the ground station. see image 3 A schematic plan view of the coexistence of the wide-coverage cell of the mountain station and the conventional cell of the ground station is shown, which will be described in detail below.

[0027] The wireless communication network system provided by the present invention includes: a wide-coverage cell using the first carrier frequency; one or more conventional cells located in the wide-coverage cell and using a carrier frequency different from the first carrier frequency, wherein The different conventional cells may use the same or different carrier frequencies.

[0028] The following example explains in detail:

[0029] In the target coverage area, if there are wide coverage facilities such as high mountains or high towers, and when there are two or more available ...

Abstract

The invention relates to a radio communication network system, comprises: a wide coverage cell used the first carrier frequency; one or more common cells whose carrier frequency is different from the first carrier frequency in the wide coverage cell. The access method of the network system comprises judging the terminal accessed to the wide coverage cell whether in a common cell thereof or not, if yes, the terminal is controlled to access the common cell. The invention solves the problem that existing network mountain stations have interferences to earth stations in coverage area thereof, thereby the mountain stations can not be removed, and solves the problem of telephone variable-density coverage in wide area.

Description

technical field [0001] The invention relates to a wireless cellular communication system, in particular to a wireless communication network system and an access method thereof. Background technique [0002] In the planning and construction of wireless communication networks, the following situations are often encountered: [0003] The area that needs to be covered is vast, but the traffic density of users within the coverage area varies greatly. Often, users are highly concentrated in some small areas, while users in other larger areas are sparse. Such as figure 1 In the example shown, towns and towns belong to areas with small areas but dense users, while rural areas and pastures have vast areas but sparse users. Nevertheless, the network is also required to cover these areas. [0004] According to the conventional network planning method, it is generally required that the cells are distributed according to the planar cellular topology, each cell has its own relatively cl...
