Method for service allocation in layered network

Abstract

This invention relates to a method for distributing services in a hierarchical network including: distributing low speed service to a macro-area in large cover sphere and small volume by the kind of the area and the kind of the service applied by the user so as to eliminate the interference to the users in the micro-areas by the low speed service, distributing the high speed data service to the micro-areas in small cover conditions and better channel conditions to provide high quality data transmission for the high speed data service.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for service distribution in a layered network. Background technique [0002] In the initial stage of mobile communication system application, because the traffic volume is not large, often a cell covers a relatively large area. With the increasing number of users, it is difficult for the system to meet the increasing traffic demand. At this time, a cell with a different frequency is often added in some areas to absorb the traffic. In this way, multiple different-frequency cells cover the same area, such as figure 1 As shown in , among the three areas A, B, and C, areas A and B have more traffic, and they are covered by two cells with different frequencies (the cells are configured with frequencies f1 and f2 respectively). [0003] As the traffic continues to increase, it is necessary to further expand the system in hot spots with a lot of traffic, such as establishing a hiera...

Problems solved by technology

[0014] In view of the existing problems in the above-mentioned prior art, the purpose of the present invention is to provide a method for service distribution in a layered network. The low-speed services caused by the reasonable allocation of the services among different layers of cells in the hierarchical cell structure cause interference to users in the micro-cells, and it is impossible to ensure that high-speed data services are allocated to small coverage areas and channel conditions. A relatively good micro cell provides high-quality data transmission that meets the requirements for high-speed services; at the same time, it solves the problem of establishing the service requested by the user directly in the residential cell where the user initiates the request in the prior art. High-speed data services may occupy the capacity of the macro cell, resulting in the problem that the establishment of services in the macro cell is prone to failure
