Abstract

The method comprises: when MS/AT is switched to HRPD network, and after the message is informed to MSC through AN, if the voice service of 3G1X arrives, the MSC sends the paging request message to the related 3G1X BS, and meanwhile sends a notice message about the voice call to AN through ALP interface; AN puts the paging request or service notice message from MSC into the HRPD 3G1X packet and sends it the MS/AT; MS/AT responds to the AN and waits user to make selection for the 3G1X voice service; if user selects the answering, MA/AT stops the service in HRPD network, switches to the 3G 1x network and sends the paging response message to 3G1X BS; if user reject call, MS/AT will keep the HRPD service state and doesn't switch to 3G1X network. The arrival information transmitted from MSC to AN includes calling number and calling name by which user at HRPD network can judge the importance of 3G1X incoming call.

Description

User under the high-speed packet data network receives and handles the method for 3G1X audio call

Technical field

The present invention relates to high-speed packet data network and 3G1X network interoperability scheme, particularly the user under the high-speed packet data network receives and handles the method for 3G1X audio call.

Background technology

In the 3G networking, HRPD (high rate packet data) (hereinafter to be referred as HRPD) network as main bearing data service, how occurring with the 3G1X network associating network's mode with main voice-bearer and low-speed data service, the user uses 3G1X/HRPD dual-mode terminal (hereinafter to be referred as MS/AT) to insert.Need the link that connects between 3G1X network and HRPD network, to support the mutual of calling control between two nets and information such as mobile management.For example, when session control/mobile management (hereinafter to be referred as SC/MM) function of HRPD net is in Access Network (hereinafter to be referred as AN), set up special purpose interface A1p between the AN that can net, be used for carrying calling control and mobility management information among the MSC and between the AN at the mobile switching centre (hereinafter to be referred as MSC) and the HRPD of 3G1X net.The HRPD interoperability structure reference model of setting up behind the A1p interface is seen Fig. 3.At this moment, should establish special-purpose interoperability module IWS in logic (Interworking Solution) among the AN, IWS is used to realize the message on the A1p interface and the conversion of the 3G1X service message on the air interface.By means of IWS, after the user forwarded under the HRPD network and passes through A1p interface notice MSC, if there is the 3G1X beep-page message to arrive MSC, MSC can be delivered to MS/AT by AN again by A1p interface notice AN.

Scheme according to present 3GPP2, under the situation that has the 3G1X audio call to arrive, MSC sends the professional arrival information of 3G1X by paging request message to AN, owing to can not carry calling number and caller name in the paging request message, can only be after MS/AT interrupts current HRPD business and forwards the 3G1X network to, the user just can see calling number and caller name, and whether decision answers.Call out even if user's this moment is reluctant to answer this 3G1X, the HRPD business has also been interrupted.In brief, the problem of scheme existence at present is that the user is under the situation of carrying out the HRPD business, when the 3G1X audio call arrives, calling number and the caller name of user because of learning the 3G1X audio call, can't make the selection of whether answering this audio call in that HRPD is off the net, bring following problem:

1.HRPD professional interruption

MS/AT has only the current HRPD business of interrupting earlier, forward the 3G1X network then to and just can see the calling number and the caller name of 1X incoming call, if this moment, the user did not wish to answer this incoming call, will refuse the HRPD net of transferring from a team to another behind this incoming call, but cause the interruption of HRPD business.

2.3G1X waste of network resources

The user just can see the calling number and the caller name of 1X incoming call after MS/AT forwarded the 3G1X network to and sets up airlink, if this moment, user's refusal was answered, the 3G1X network causes the 3G1X waste of network resources for the resource of this call distribution is nonsensical.

Summary of the invention

For addressing the above problem, the purpose of this invention is to provide the method that user under a kind of high-speed packet data network received and handled the 3G1X audio call,

For achieving the above object, the user under a kind of high-speed packet data network receives and handles the method for 3G1X audio call, comprises step:

A) when MS/AT forward under the HRPD network and by AN notice MSC after, arrive if any the speech business of 3G1X, MSC sends paging request message to relevant 3G1X BS, sends notification message about this audio call by the A1p interface to AN simultaneously;

B) AN paging request that MSC is sent or service announcements message are put in the HRPD 3G1X business packet and are handed down to MS/AT;

C) MS/AT AN is responded and wait for the user at 3G1X speech business select;

D) if the user selects to answer, MS/AT will stop at the business in the HRPD net, forward in the 3G1X net, and send the message that pages reply to 3G1X BS;

E) if user's refusal is answered, MS/AT will keep the HRPD service condition with MS/AT, not turn to the 3G1X net.

According to the present invention, MSC will comprise calling number and caller name in the professional arrival information of the 3G1X that AN transmits, make and to judge the importance that 3G1X sends a telegram here according to calling number and caller name HRPD user off the net, and whether decision forward that 3G1X is off the net to answer this callings to, can avoid the interruption and unnecessary the taking of 3G1X Internet resources of the HRPD business that causes because once unessential 3G1X sends a telegram here.

Embodiment

The present invention comprises that mainly MSC arrives information processing, AN to the 3G1X audio call processing, the MS/AT of 3G1X speech call information received the action after the 3G1X audio call message, the forwarding that AN is receiveed the response to MS/AT, the processing that MSC responds MS/AT etc.

1.MSC the 3G1X audio call is arrived information processing

When receiving a user's voice calling of pointing in its service-domain, MSC sends paging request message or service announcements message by the A1p interface to HRPD AN, if MSC has learnt the calling number and the caller name of this calling, MSC will carry calling number and caller name in paging request or service announcements message.Simultaneously, MSC starts clock T3113 and T3113-2.Subsequently MSC to this called MS/AT the one or more service 3G1X BS that may get in touch send paging request message.This paging request message may comprise virtual call indication (hereinafter to be referred as VPI) need not send General Page Message to called MS/AT with notice 3G1X BS on eating dishes without rice or wine.

2.AN processing to the 3G1X speech call information

After AN receives the paging request or service announcements message that MSC sends, paging request or service announcements message are encapsulated in the 3G1X business packet, send to MS/AT through the HRPD air interface.

3.MS/AT receive the action after the 3G1X audio call message

After MS/AT receives the 3G1X business packet that includes paging request or service announcements message, should send portable terminal to AN and confirm order, to show the 3G1X speech business notification message of having received that AN sends.MS/AT should point out the user to select whether to answer this calling simultaneously, if carry calling number and caller name in paging request or the service announcements message, MS/AT also will be shown to the user to calling number and caller name.The user can select by man-machine interface, and MS/AT does not interrupt ongoing HRPD business in user's selection course.If the user sets in MS/AT in advance at 3G1X voice incoming call, MS/AT will operate by setting in advance of user.

If the user selects to answer, MS/AT forwards the 3G1X net to, construct the message that pages reply according to the message elements in paging request or the service announcements message and issue the 3G1X base station system, 3G1X base station system structure comprises complete layer 3 information that page reply and sends to MSC, and MSC stops the T3113-2 clock.Subsequent operation will be undertaken by the 3GPP2 standard, in the step afterwards, because the user has made the selection of whether answering, can save the step that shake bell and user select; If user's refusal is answered, MS/AT will keep the HRPD service condition, not turn to the 3G1X net.

4.AN the forwarding that MS/AT is receiveed the response

AN receives after 3G1X portable terminal that MS/AT sends confirms order, structure service announcements response message, and send to MSC by the A1p interface.

5.MSC processing to the MS/AT response

MSC will stop clock T3113 after receiving the service announcements response message that AN sends by the A1p interface.If MSC did not receive the service announcements response message that AN sends before clock T3113 was overtime, MSC will retransmit paging request or service announcements message to AN, retransmit paging request message up to reaching predefined repeating transmission number of times to the 3G1X base station.If MSC has received the message that pages reply that send the 3G1X base station before clock T3113-2 is overtime, MSC will continue the audio call flow process of back according to the 3GPP2 related specifications; If MSC does not receive the message that pages reply before clock T3113-2 is overtime, MSC will end this time audio call, and according to 3GPP2 related specifications caller notification.

6. the transformation of paging request and service announcements message

For the function that realizes that this patent will reach, need transform paging request and service announcements message.For the paging request, need to increase special information unit and carry calling number and caller name; For service announcements message, need to increase the information unit of carrying service option.MSC also can send this two message to AN simultaneously, at this moment, does not need to increase new information unit in these two message.

In above step, clock T3113-2 also can finish the back at T3113 and start.

The message flow that the user answers the 3G1X audio call as shown in Figure 1;

The message flow that the user refuses the 3G1X audio call as shown in Figure 2.
