Traditional voice service mainly is the conversation of point-to-point, and this requires the bi-directional speech channel to set up simultaneously, guarantees the synchronous of conversation, and the voice service of cordless communication network has also been inherited this characteristics.Development along with value-added telecom services, comprise that emerging technologies such as call center, telephone message make voice service to development in pluralism, particularly wireless network develops on an unprecedented scale, valuable frequency resource makes RRM become very important, therefore at the segmentation of voice service, adopt different radio channel allocation strategies to seem very necessary.
And existing channel allocation is not considered the diversity of voice service, need set up the professional just part of voice service of point-to-point bi-directional speech of two-way channel simultaneously, distribute two-way channel at the very start for unidirectional voice service, not only can cause especially waste of radio resources of channel resource, and increase the complexity of resource management.
Summary of the invention
The invention provides a kind of voice channel distribution method of radio communication, to solve in the prior art because unidirectional voice service distributes two-way channel to have the especially problem of waste of radio resources of channel resource.
A kind of voice channel distribution method of radio communication, this method is:
A, user make a call;
B, mobile switching centre determine the voice service type of described calling;
If the described calling of C is the bi-directional speech business, mobile switching centre then is this call distribution bi-directional speech channel, if be unidirectional voice service, mobile switching centre then is the unidirectional voice channel of this call distribution.
According to said method:
Mobile switching centre receives that called agreement sets up execution in step B behind the response message of calling out.
In communication process, it is professional or when being converted to unidirectional voice service by the bi-directional speech business that voice service is converted to bi-directional speech by unidirectional voice service, mobile switching centre's reprovision voice channel.
The upper strata that keeps during the reprovision voice channel calling out connects.
Mobile switching centre determines the voice service of calling according to the information of carrying in call request message in the signaling network flow process or the response message; Perhaps the number of preserving in call number and the database is mated to determine the voice service type of calling.
Described channel comprise mobile switching centre to the dedicated transmission channel between the base station system and base station system to the dedicated wireless channel between the travelling carriage.
The inventive method is judged the voice service type earlier owing to having adopted before mobile switching centre's allocation of channel resources may, and the method for making corresponding initial channel distribution according to judged result, for unmarried voice service only schedule of apportionment to voice channel, abandoned that prior art is not distinguished the voice service type and the method for distributing a pair of voice channel without exception, thereby the especially radio channel resource of channel resource that can not only avoid waste, also can improve the quality of radio communication.

Embodiment
A typical wireless communication system comprises travelling carriage (MS), base station system (BSS) and mobile switching centre (MSC), and in this system, the voice service channel is managed by mobile switching centre and distributes, as shown in Figure 1.
In order to save especially radio channel resource of channel resource, the present invention already distributes voice channel according to the voice service type of calling out.After the calling request is received by mobile switching centre, set up calling to called request, after receiving that the response of calling out is set up in called agreement, judge the voice service type earlier, and then the distribution voice channel.For point-to-point bi-directional speech business, distribute a pair of voice channel, promptly up voice service channel and down voice Traffic Channel; For the down voice business, an allocation of downlink voice channel; For up voice service, only distribute up voice channel.The voice channel here comprise MSC to the dedicated transmission channel between the BSS and BSS to the dedicated wireless channel between the MS.
Mobile switching centre can determine the voice service type of calling by the signaling network flow process, this is because general calling request and response message all can carry the specific call type information, as audio call, fax, data or the like, if with special type of call such as the call center as a type of call option, then MSC can judge the voice service type according to this, therefore this mode need be revised the signaling network flow process, promptly increases new calling bi-directional speech, unidirectional up speech and unidirectional down voice traffic type information and these types are judged.
Mobile switching centre also can determine the voice service type of calling by Query Database.In this manner, only need if the call number in call request message and these special numbers meet, just can determine corresponding special calling type at all special calling numbers (being unidirectional up) of mobile switching centre's registration storage.As: provide the call center numbers of unidirectional up and unidirectional down voice business to be registered in mobile switching centre all, if call number in the call request message and numbers match wherein then can determine it is unidirectional voice service, otherwise be defined as the bi-directional speech business.Adopt this method need not revise signaling process.
Consulting shown in Figure 2ly, is called with travelling carriage, and the voice channel assigning process is as follows:
S1, caller are called out to Mobile Origination.
After the calling request is received by S2, mobile switching centre, set up calling to the travelling carriage request by paging.
The response message that travelling carriage agreement foundation is called out is received by S3, mobile switching centre.
S4, mobile switching centre judge the voice service type of this time calling by the signaling network flow process, if the bi-directional speech business is then carried out step S6; If unidirectional voice service is then carried out step S5.
S5, mobile switching centre carry out initial channel and distribute, for the down voice business, and an allocation of downlink voice channel; For up voice service, only distribute up voice channel.
S6, mobile switching centre are a pair of voice channel of point-to-point bi-directional speech traffic assignments, promptly up voice service channel and down voice Traffic Channel.
In communication process, when unidirectional voice service and bi-directional speech business change, mobile switching centre's reprovision channel.The processing procedure of reprovision channel may be not quite alike in different communication systems, but rule will keep upper strata (application layer) to connect exactly, simplifies signaling process as far as possible.The most direct a kind of method is exactly the configurating channel before discharging earlier, redistributes new channel then.For example: transfer the bi-directional speech business to from unidirectional down voice business, mobile switching centre discharges original unidirectional down voice channel, for this business is redistributed the bi-directional speech channel under the situation that keeps the upper strata to connect.
The conversion of unidirectional voice service and bi-directional speech business can be judged by user's operation by detecting, by predetermined conversion key, Mobility Center detects can judge after this operation and need carry out unidirectional voice service and bi-directional speech is professional changes as user in communication process.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
