Abstract
The present invention discloses a method for realizing voice precedence service in data and voice interaction used in a CDMA mobile communication network. In the present invention, after a mobile switching center receives a voice incoming call from a mobile station aiming at underway data communication, the mobile switching center checks and judges if the voice precedence service in the current mobile station is in an activated state, if false, the mobile switching center refuses the voice incoming call and ends the procedure of the method; if true, the mobile switching center sends a message for instructing in starting the mobile station to be in the dormant state procedure to a base station; after the base station receives the message, a processing procedure is started to enable the mobile station to be in a dormant state, and then the voice incoming call is processed according to the processing procedure of the mobile station in the dormant state. Using the present invention can simplify the whole realization procedure of the voice prior service, can raise the processing speed of the procedure, and can reduce response time of the mobile station.
Description
Technical field
The present invention relates to implementation method professional in the wireless communication system, be specifically related to the implementation method of voice priority business in a kind of code division multiple access (CDMA) system data and the interactive voice.
Background technology
In the cdma system protocol specification, there are three kinds of states in the user data service operation: idle condition, state of activation and resting state.Portable terminal is under state of activation, if system does not support voice and packet data concurrent service, therefore the user can not may miss some important incoming calls as speech called in data interaction so.Even system supports voice and packet data concurrent service, still there are a large amount of portable terminals not support the function of voice and packet data concurrent service at present, these mobile terminal user can not receive incoming call equally when using data service, brought great inconvenience to the user.
In order to address this problem, proposed to receive under a kind of situation of carrying out data service at travelling carriage (MS) method of audio call at present, its handling process is as shown in Figure 1.As shown in Figure 1, when travelling carriage is carrying out data service and at this moment new audio call is being arranged, at first send a beep-page message for base station (BS) by mobile switching centre (MSC), the base station receives removing request from this beep-page message to MSC that return the current data business of requesting timeout behind, MSC sends a clear command message to the base station then, clear operation is promptly carried out in the base station, comprise that A9 between base station and the packet data control function (PCF) is released to A8 and A9 is released to the step that A8 finishes, after clear operation is finished, at this moment travelling carriage is in the data service dormancy and the state of retention point end-to-end protocol (EEP) (PPP) connection, this moment, the base station sent a beep-page message to travelling carriage again, thereby travelling carriage can carry out normal voice dialogue.PDSN among Fig. 1 is the packet data service node.
In this method, because the beep-page message that the base station receives is a connectionless beep-page message, the travelling carriage talking state of this moment is not also known in just common base station, for example travelling carriage is carrying out voice call at this moment, is using data service still to be in idle condition, because user's current state can not be distinguished in the base station, therefore being difficult to decision is this beep-page message directly to be issued or temporary transient earlier the preservation.For example,, then need temporarily to preserve this beep-page message, carry out issuing again after the dormancy etc. data if travelling carriage is carrying out data service this moment; If travelling carriage is idle, then this beep-page message directly can be sent to travelling carriage.And under the situation that can not know mobile station state, the base station is difficult to be for further processing, and therefore this method is impracticable in actual conditions.
Simultaneously,, MSC removes request because after the base station sends a beep-page message, needing the base station to return one, thus the interacting message complexity, reduced response speed, prolonged the response time.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of implementation method of handling voice priority business in data simple, that response speed is fast and the interactive voice.
Above-mentioned purpose of the present invention is solved by the following technical solutions:
The implementation method of voice priority business comprises the steps: in a kind of data and the interactive voice
A. mobile switching centre receives at behind the voice of the travelling carriage that the carries out data communication incoming call, check also to judge whether the state of voice priority business in the current mobile station is state of activation, if, execution in step b then, otherwise refusal voice incoming call, process ends;
B. mobile switching centre sends clear command message to the base station, includes the cause specific value that the base station initiated travelling carriage of indication enters the resting state flow process in this clear command message;
C. the base station receives after the clear command message of step b transmission, starts to make travelling carriage enter the handling process of resting state, described voice incoming call is handled in the handling process of resting state according to travelling carriage then.
This method may further include the step that sets in advance this cause specific value.
In the implementation method of above-mentioned voice priority business, the state of voice priority business comprises that further activation, deexcitation, single activate and the single deactivation status.Wherein, activation and deactivation status are stored in the call features indicating device that is arranged in attaching position register, and single activates and the single deactivation status is stored in the single feature indicator that is arranged in mobile switching centre.When travelling carriage carried out location registers, attaching position register sent the activation or the deactivation status information of current mobile station to mobile switching centre.
By technical scheme of the present invention as can be seen, owing in the clear command message that the base station sends, increased the cause specific value of an expression travelling carriage voice priority business enrollment status in mobile switching centre, and mobile switching centre can know clearly the state of travelling carriage this moment, so the base station can start clearly and makes travelling carriage enter the flow process of resting state.Because the voice priority business is started by mobile switching centre among the present invention, be different from the prior art by base station initiated, and mobile switching centre is different with the base station, it can know the service condition of travelling carriage clearly, therefore the present invention has avoided that the base station is difficult to determine to send the order or the difficult problem of temporary order in the prior art, and it is simpler that whole service is handled.
In addition, return the step that removing is asked because the present invention has omitted the base station to mobile switching centre, therefore the interacting message of whole flow process is simpler, thereby has accelerated response speed, has reduced the response time.

Embodiment
The present invention is described in detail below with reference to the drawings and specific embodiments.
The voice priority business can be used as a business as Call Waiting and is provided by system operator, if the user wishes to use this business can select to the system operator registering, other are professional the same for its registration and the flow process of opening and Call Waiting etc., difference is business operation sign indicating number difference, and the voice priority business also can be registered as activation or the deexcitation of single activation/single simultaneously.Usually, the command code of Call Waiting is:
*The deexcitation of 700-single,
*The 74-activation,
*The 740-deexcitation, the command code that correspondingly can define the voice priority business is:
*The deexcitation of 710-single,
*The 77-activation,
*The 770-deexcitation.The single here activates owing to can not use in actual conditions, thereby does not in fact have corresponding command code.The command code here just is used for system operator does not have direct relation to a kind of sign and the present invention of different business.
After the user had opened this business, system need change the D interface agreement, just increased the state indication of voice priority business at the call features indicating device (CallingFeaturesIndicator) that is arranged in attaching position register (HLR).Fig. 2 is the structure chart of call features indicating device.In call features indicating device shown in Figure 2, can enable the reservation position and represent the state that voice are preferential.For example, the preferential state of H/G bit representation voice of the 5th byte is set, can be set at: H/G 0/0-does not use; H/G 0/1-unauthorized; H/G 1/0-authorizes but un-activation; H/G 1/1-authorizes and activates.At user's registering after the voice priority business, single activation state can further be set, this carries out record by the single feature indicator (OneTimeFeatureIndicator) that is positioned at mobile switching centre as shown in Figure 3.Can enable the reservation position equally and represent the single state that voice are preferential.For example, the F/E that second byte is set is the preferential single state of expression voice, and can be set at: F/E 0/0-does not use; F/E 0/1-unauthorized; F/E 1/0-authorizes but un-activation; F/E 1/1-authorizes and activates.
System has changed after the D interface agreement, has just increased the state indication about the voice priority business in HLR.As shown in Figure 4, when user's travelling carriage carries out location registers, MSC/VLR sends a registration notification to HLR, HLR returns to MSC/VLR with user data, all professional state indications in the user data that returns, have promptly been comprised, just comprise the information that the call features indicating device that is arranged in HLR is comprised, also comprised the state indication of voice priority business certainly.This process is identical with prior art, therefore repeats no more.
Following mask body is introduced travelling carriage and receive system handles flow process under the audio call situation when being carried out data service.
As shown in Figure 5, in step 501, after user's mobile station login has been opened the voice priority business, when user's travelling carriage carries out data service, if MSC receives the voice incoming call, to check at first whether the voice priority business activates, just read the call features indicating device that obtains from HLR and the voice priority business enrollment status in the single feature indicator the MSC itself.
In step 502, MSC judges whether current mobile station voice priority business is state of activation.Just, MSC checks whether the value of the H/G position of the 5th byte in the call features indicating device is 1/1, if not 1/1, shows that then user's travelling carriage does not use the voice priority business, and execution in step 507 is just refused the voice incoming call, process ends; If 1/1, whether the value that then reexamines the F/E position of second byte in the single feature indicator is 1/1, if not 1/1, show that then the user does not this time use the voice priority business, execution in step 507, if 1/1, just user's travelling carriage voice priority status at this moment activates, show that then the user will use the voice priority business, execution in step 503 this moment.
In step 503, MSC sends a clear command message to the base station, and in clear command message, increase a cause specific value, this cause specific value is used to refer to data service and enters dormancy, just it shows that the base station initiated user's travelling carriage of requirement enters the flow process of resting state, and this cause specific value for example can be defined as 10H.Increasing this cause specific value is core processing of the present invention, here owing to be that MSC is handling, therefore it can know the state that travelling carriage is present, for example travelling carriage is in the conversation, still be in idle condition etc. in the data communication, can directly allow the base station know that travelling carriage is carrying out data communication at present by increasing a cause specific value, and need make user's travelling carriage enter the resting state flow process, the base station can directly start allows travelling carriage carry out the flow process of resting state, then incoming call is sent to travelling carriage, thereby make entire process flow process of the present invention simpler, more practical, and shortened the response time.
In step 504, the base station is after receiving this clear command message, be checked through the cause specific value of 10H by name, know that promptly needing to start user's travelling carriage carries out resting state, remove the user's data service communication according to step same as the prior art then, make user's travelling carriage enter the data service resting state and the state that still keeps PPP to connect.
In step 505, the base station is returned removing to MSC and is finished message after finishing the clear command message processing.
In step 506, MSC waited for for 2 seconds after receiving that message is finished in removing that the base station is returned, restart called flow, just sent beep-page message to the base station earlier, and the base station sends beep-page message to travelling carriage then.Travelling carriage can be replied incoming call, and this moment, the user travelling carriage did not receive the data that issue on the net, can be finishing speech business after by user's travelling carriage active activating data service, also can have on the net newly to data message the time activate again.
Handling process of the present invention has been described above.Fig. 6 is a handling process schematic diagram that contrasts with prior art.From Fig. 6, can be clear that, the present invention is when the incoming call of voice incoming call, voice priority business enrollment status among the priority check MSC, if professional enrollment status is a state of activation, then can directly send clear command message to the base station, and in clear command message, have a cause specific value, thereby cancelled the step that directly sends beep-page message in the prior art and return the request of removing by the base station to the base station, therefore entire process process of the present invention is simpler, clear and clear and definite, has avoided the shortcoming of prior art effectively.
Need to prove that the present invention can realize the voice priority business simply, and in actual conditions, system can come processed voice priority business and other professional priority treatment order according to voice priority business and other professional severity levels.For example, the user divert when busy (CFB), changes (CFD) before default and has precedence over the voice priority business when carrying out speech business or voice and packet data concurrent service, and the user is when carrying out data service, and the voice priority business has precedence over CFB and CFD.Voice priority business and Call Forwarding No Reply (CFNA) or Call Waiting (CW) are separate, when speech business is linked into the busy user's travelling carriage of data service, and the voice activated priority business of system, rather than CFNA or CW.Show (CNAP) and voice priority business if the user activates the caller name simultaneously, perhaps activate caller ID display (CNIP) and voice priority business simultaneously, caller name or calling number should send by voice priority business notification message.In addition, Call Forwarding Unconditional (CFU) and interruption-free (DND) business all have precedence over the voice priority business.
Being appreciated that above is to specific descriptions of the present invention, and not in order to restriction the present invention.
