Problems solved by technology

But the problem is that the characteristics of the PHS system determine that the coverage of the PHS base station cannot be improved qualitatively. Using a large number of service channels in a small coverage area will lead to a waste of a large number of service channels. Moreover, as the coverage increases , whether the control channel can carry the user's signaling message capacity is also a problem that must be considered

Embodiment Construction

[0019] Basic idea of ​​the present invention is:

[0020] Due to overlapping coverage of base stations, a mobile phone can receive signals from multiple base stations at the same time. However, when the mobile phone initiates a call, it will only select the base station that it is synchronously tracking to initiate a call request; at the same time, the mobile phone will only monitor the downlink paging channel PCH (Paging Channel, paging channel) of the base station when it is in standby. When a mobile phone initiates a call, it must go through a signaling interaction process on the control channel CCH. Therefore, if when the mobile phone initiates a connection channel establishment request to a certain base station, if there is good air synchronization, other base stations can also monitor the connection channel establishment request message of the mobile phone, then we can rely on the resources of the base station controller Management and coordination to achieve the purpos...

Abstract

The invention is a resources distribution method between base stations in the personal handle system, all the base stations in network can monitor the connecting channel creation application information in the up SCCH channel, when the mobile phone calls one base station, if the base station has idle resources, it distributes the resources normally; if the called base station has no idle resource, it applies to the base station controller, the base station controller controls other base station with idle resources to distribute resource to the mobile phone. The invention reduces the accessing time in the PHS network, upgrades the call achieving rate and the switch achieving rate of the user, upgrades the channel distribution rate of the PHS network greatly, and it uses the wireless resources of the network effectively.

Description

technical field [0001] The present invention relates to a radio resource allocation method in PHS (Personal Handy Phone System, personal hand-held system). Background technique [0002] PHS technology is a micro-cellular technology, focusing on the application of mobile voice and data services under high traffic density and low moving speed. In the existing PHS air interface protocol, the wireless resource management method is relatively simple, basically adopting the method of "randomly initiated by the mobile phone and managed by the base stations separately": the resource status of each base station is managed by each base station itself, and the mobile phone does not initiate a call when it initiates a call. It cannot be known whether the base station receiving its call request has free resources. This will lead to a higher rejection rate when the network time slot is busy or the frequency is busy, especially in traffic hotspots, which not only prolongs the call connect...
