Embodiment
The invention provides the method for transmitting user's input information in a kind of cordless communication network, core of the present invention is: user's input information is carried in the OPTION message of START DTMF message, STOP DTMF message and SIP (initial session protocol) and transmits.
Describe the present invention in detail below in conjunction with accompanying drawing, the method of the invention is applicable to the cordless communication network that ALL IP (all-IP), carrying control separate, and the cordless communication network that described ALL IP, carrying control separate comprises: CDMA2000 LMSD and CDMA2000 MMD (multimedia domain, MMD) network.
CDMA2000 All-IP core network system is split as MSCe (mobile soft switch center) and MGW (media gateway)/two core network elements of MRFP (Media Resource Function Processor) with the MSC network element among the CDMA mobile network, MSCe and MGW/MRFP can substitute traditional MSC function fully, MSCe is responsible for calling out functions such as control, mobile management, and MGW/MRFP is responsible for the media bearer function.Traditional voice service can substitute the TDM transmission by the IP transmission.
With CDMA2000 LMSD network is example, the realization schematic diagram of the embodiment of the method for the invention as shown in Figure 3, the flow chart of concrete processing procedure comprises the steps: as shown in Figure 4
Step 41, as shown in Figure 3, the present invention at first need be provided with START DTMF (beginning dual-tone multifrequency) message, STOP DTMF (stopping dual-tone multifrequency) message at MS (user terminal) in BSS (base station sub-system), A interface, ZZ interface.
Above-mentioned START DTMF message begins to import the back the user and sends on MS, and carries user's input information.Above-mentioned STOP DTMF message stops on the MS the user and sends behind the input information.
Before beginning to carry out once concrete session between MS and the MSCe under it, between BSS and the MSCe under it, need to carry out resource allocation.The BSS at first MSCe under it sends CMService Request (Connection Service request) message, after MSCe receives this CM ServiceRequest message, sends Assignment Request (request for allocation) message to BSS.After BSS receives this Assignment Request message, carry out resource allocation such as corresponding bandwidth after, the MSCe under it sends Assignment Complete (having assigned) message.
Step 42, after beginning to carry out once concrete session between MS and the MSCe under it, begin carrying out on the MS input information operations such as button input or handwriting input the user after, the START DTMF message that the MS structure carries user's input information, and sending the START DTMF message of structure to BSS, BSS passes to MSCe under it by the A interface with the START DTMF message that receives again.
Zz interface between the MSCe is based on Session Initiation Protocol, so, MSCe under the above-mentioned BSS carries above-mentioned START DTMF message in the OPTION of Session Initiation Protocol message, and with this option withSTART DTMF (carrying the option of beginning dual-tone multifrequency information) target MSC e that message passes to PSTN (public switch telephone network)/PLMN (public land mobile network) links to each other.
In said process, the MSCe under the BSS also sends START DTMF ACK (replying) message to BSS, and the target MSC e also MSCe under BSS sends option with START DTMFACK (option that carries beginning dual-tone multifrequency information is replied) message.
Step 43, the user stop at carry out input information operation on the MS after, MS sends STOP DTMF message to BSS, represents this user's input information EO.BSS passes to MSCe under it by the A interface with the STOP DTMF message that receives again.
MSCe under the above-mentioned BSS carries above-mentioned STOPDTMF message in the OPTION of Session Initiation Protocol message, and this option with STOP DTMF (carrying the option that stops dual-tone multifrequency information) message is passed to the target MSC e that links to each other with PSTN/PLMN.
In said process, the MSCe under the BSS also sends STOP DTMF ACK (replying) message to BSS, and the target MSC e also MSCe under BSS sends option with STOP DTMFACK (carrying the option that stops dual-tone multifrequency information replys) message.
After the user repeats repeatedly the input information operation, repeat the transmittance process of above-mentioned START DTMF message, STOP DTMF message, up to all button operations end of user, behind this conversation end, execution in step 44.
Step 44, the BSS MSCe under it sends clear Request (removing request) message, after MSCe receives this clear Request message, sends clear Command (clear command) message to BSS.After BSS receives this clear Command message, after the resources such as release corresponding bandwidth, send clear Complete (removing is finished) message to MSCe.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
