Problems solved by technology

If the base station ID planning is reasonable, then the traffic can be evenly distributed on all available carrier frequencies. However, in practical applications, many networks are constantly upgrading, expanding, and improving. The grouping is also fixed, so it is difficult to adapt to the changes of the PHS network, so there will be serious carrier frequency interference in some areas, and the system performance will decline

Embodiment Construction

[0036] In the PHS air synchronization system, generally, base stations are divided into five synchronization types of base stations according to the synchronization level, that is, according to the synchronization level from high to low, they are master base station (Master CS), level 1 slave base station ( Slave-1CS), level 2 slave base station (Slave-2CS), level 3 slave base station (Slave-3CS), and independent operation base station (Free-running CS).

[0037] The master base station (Master CS) has a GPS (Global Position System, Global Positioning System) receiver, which is synchronized with GPS; the level 1 slave base station (Slave-1CS) is a base station directly synchronized with the master base station (Master CS); the level 2 slave The base station (Slave-2CS) is directly synchronized with the first-level slave base station (Slave-1CS); the third-level slave base station (Slave-3CS) is directly synchronized with the first-level slave base station (Slave-1CS) or the sec...

Abstract

The invention relates to one PHS communication system optimization signal channel align method, which comprises signal align optimization management units and comprises the following steps: a, the said signal channel optimization management unit sends requires to aim base station; b, the said aim station receives above requires and responds the needed relative information; c, the said signal channel align optimization unit from aim base station to process the class frequency sets.

Description

technical field [0001] The present invention relates to a PHS communication system, in particular to a channel allocation method in the PHS communication system. Background technique [0002] At present, with the wide application of the PHS (Personal Handy-phone System: Personal Handy-phone System) communication system, the number of users of the PHS communication network continues to increase, and the communication capacity of the system is also more strained. Although the time slot resources in the system can be expanded by increasing the density of PHS base stations (Cell Stations), the problem of insufficient frequency resources in the PHS communication system is still difficult to alleviate. [0003] In a wireless communication system, channel allocation methods are usually divided into three types: Fixed Channel Allocation (FCA: Fixed Channel Allocation), Random Channel Allocation (RCA: Random Channel Allocation) and Dynamic Channel Allocation (DCA: Dynamic Channel All...
