Background technology
In existing trunking communicating technology, have two kinds of trunking communication channels: a kind of is cluster 1.0 channels, and another kind is cluster 1.5 channels.For cluster 1.0 channels, shared same the Traffic Channel of the calling terminal of same sub-district and terminal called, calling terminal takies the uplink downlink of Traffic Channel, the down link of terminal called monitoring service channel.For cluster 1.5 channels, the calling terminal of same sub-district and terminal called take a Traffic Channel respectively, and calling terminal takies dedicated channel, and terminal called takies group-calling channel.
When adopting cluster 1.0 channels to carry out trunking communication, because the calling terminal and shared same the Traffic Channel of terminal called of same sub-district, so can save channel resource, effectively improve the utilance of trunking communication channel, be suitable for the big trunking communication of channel load, can be for more terminal provide cluster communication service, and then effectively improved the capacity of trunked communication system.But, because calling terminal and shared same the Traffic Channel of terminal called, calling terminal can be heard echo, so adopt cluster 1.0 channels to carry out trunking communication, greatly reduces the cluster calling quality. even might influence the realization of normal cluster communication function.
When adopting cluster 1.5 channels to carry out trunking communication, because calling terminal and terminal called take a Traffic Channel respectively, calling terminal can not heard echo, terminal called can receive the voice messaging of dispatching desk by the group-calling channel that takies in addition, so the cluster calling quality is very high, be suitable for the demanding trunking communication of speech quality.But,, so reduced the utilance of channel, wasted a large amount of channel resources, and then greatly reduced the capacity of trunked communication system because calling terminal and terminal called take a Traffic Channel respectively.
In the prior art, the trunking communication channel is a terminal distribution by mobile switching centre (MSC).After terminal was initiated trunked call, the call information that base station controller (BSC) will be received from terminal reported MSC, MSC during according to system group network the channelling mode in self configuration be terminal distribution trunking communication channel.If the channelling mode that disposes on MSC during system group network is cluster 1.0 channels, then MSC is terminal distribution cluster 1.0 channels; If the channelling mode that disposes on MSC during system group network is cluster 1.5 channels, then MSC is terminal distribution cluster 1.5 channels.
From the process of above-mentioned allocated channel as can be seen, the method for allocated channel when improving power system capacity, but can not guarantee the cluster calling quality saving channel resource in the prior art; When guaranteeing cluster speech quality, but wasted a large amount of channel resources, reduced the capacity of system.
Therefore, the method for existing allocated channel can't solve the equilibrium problem between cluster speech quality and the power system capacity.

In the such scheme, described channel load thresholding disposes on MSC, judges described in the step B whether the channel load of sub-district, terminal place is undertaken by MSC above the channel load thresholding that disposes.
In the such scheme, in the information that MSC sends, utilize reserved field or new field further to increase the channel load parameter at BSC, further comprise between steps A and the step B: BSC is filled up to the terminal place cell channel load that inspection obtains in the channel load parameter of increase, and sending the information carry described channel load parameter to MSC, MSC is according to the channel load of the sub-district, channel load parameter acquiring terminal place that receives.
In the such scheme, described configurating channel load thresholding is to be the channel load thresholding of all cell configuration in BSC or the MSC scope on BSC or MSC; Whether the channel load of judging sub-district, terminal place described in the step B comprises above the channel load thresholding that disposes: whether the channel load of judging sub-district, terminal place is above being the channel load thresholding of all cell configuration.
