Description
Technical field
The present invention relates to the mobile communication technology field, be meant that especially a kind of is the method for Internet Protocol (IP) speech business with cdma2000 1x Call Transfer.
Background technology
(1x) code division multiple access (CDMA) channel of cdma2000 1x technology by a standard can support voice and data, services, and has many performances more more superior than other technologies.The twice of cdma system capacity before its capacity approaches, thus the voice service of continuous growth and the needs of wireless Internet new services can be adapted to.Simultaneously, its maximum speed can reach 153kbps, and need not sacrifice speech performance for data performance.
For the user that hope obtains more fast or more large-capacity data is handled service, the maximum speed of the data-optimized version of cdma2000---1x EX-DO can surpass 2Mbps, throughput surpasses 700kbps, it can compare favourably with wired DSL service, can also support to the strict more application of rate request, as image transmission, mass file download etc.Also with every Mbytes minimum cost transmission data, this is an important factors that promotes that wireless internet network is popularized to cdma2000 1xEV-DO.1x EV-DO will provide round-the-clock network to connect, thus make wireless network access be more prone to, quick and practical.
In the wireless cellular system, along with the CDMA user's of operator the increase day by day and the increase of user's request, cdma2000 1x system is subjected to the restriction of bandwidth and speed in carrying out high-speed data service, will introduce the data service of high-speed packet data service (HRPD) systems support high speed.Generally speaking, for while support voice and data service, meeting of HRPD system and the stack of cdma2000 1x system cover, and dual-mode terminal will become two main means that cover of netting that realize.For dual-mode terminal, HRPD protocol definition voice are preferential, and the user carries out must be able to answering the voice paging from cdma2000 1x system in the data service in the HRPD network.
In the network frame as shown in Figure 1, cdma2000 1x/HRPD dual-mode terminal is when the HRPD network carries out data service in the HRPD Rel.0 system, must be according to the beep-page message timing of cdma2000 1x network, per 1.28 seconds paging cycle forward the paging channel of cdma2000 1x network monitoring cdma2000 1x network to, judge whether the beep-page message of oneself, if beep-page message is arranged, the user will respond cdma2000 1x paging, and set up Traffic Channel in cdma2000 1x system.If there is not beep-page message, then return the HRPD network, continue ongoing data service.
HRPD ReL.A version air protocol has been done certain improvement to above-mentioned part, can allow beep-page message by HRPD forwarded cdma2000 1x, dual-mode terminal just can all switch to monitoring seek channel in the cdma2000 1x network at the paging cycle of each cdma2000 1x like this, and directly receives the voice paging message from cdma2000 1x network in the HRPD network.If cdma2000 1x voice paging message is arranged, terminal switches to cdma2000 1x network, and response cdma20001x voice paging can return the HRPD network after voice finish and continue ongoing data service.If this user's cdma2000 1x voice paging not, then this dual-mode terminal need not to switch to cdma2000 1x network.
The improvement of HRPD Rel.A has reduced the frequency that terminal switches to cdma2000 1x network, makes the power consumption of terminal reduce, owing to reduced the frequency that switches to cdma2000 1x network, the Qos of HRPD network data service is also necessarily improved simultaneously.But still there is following shortcoming in Rel.A:
Dual-mode terminal is in two nets overlay area, as long as receive the speech paging of cdma2000 1x, no matter whether the user answers, and terminal all must switch to cdma2000 1x network, and user's ongoing business in the HRPD network can be forced to switch to dormancy (Dormant) attitude.Because what switch between two nets is chronic, this as VoIP, Video Phone, PTT, Streaming Media etc., influences very big to delay sensitive type business.If it is longer that the user switches to the time of cdma2000 1x network, may cause HRPD data service suspension time to surpass the time of HRPD network Dormant timer setting and interrupt, even the user returns the HRPD network, still can't continue the user originally in the ongoing data service of HRPD network.So at present the agreement of the HRPD processing imperfection very of answering cdma2000 1x voice call for dual-mode terminal is unfavorable for that the business of HRPD network is carried out.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core content of the present invention is: the MSC/VLR of dual-mode terminal in cdma2000 1x network carries out location registers, after MSC receives the call request that contains called number, judge whether terminal called is in the HRPD network, if, MSC obtains the VoIP address that terminal called need shift, and according to the voip gateway (GW) of this VoIP addressing of address to correspondence, realizes the ip voice business, if not, carry out the regular traffic flow process.
Here, in order to make MSC get access to the VoIP address of terminal called correspondence, with cdma2000 1x Call Transfer is voip call, dual-mode terminal can directly be provided with the VoIP address of self correspondence in MSC, be called " unconditional call forwarding ", also can in calling, dynamically set according to calling number, be called " calling transfer of having ready conditions " by the called subscriber.
The process of unconditional branch setting can comprise two kinds, a kind of is in the network architecture after improvement shown in Figure 2, with being connected of the AN/PCF in the MSC in the cdma20001x network and the HRPD net, as shown in Figure 2, this networking mode is provided with the VoIP address of self correspondence at MSC by HRPD AN by the dual-mode terminal of the Idle state that is in the HRPD network; Another kind of situation is in as shown in Figure 1 the existing network framework, and the dual-mode terminal that is in cdma2000 1x network in the handoff procedure of HRPD net, is provided with the VoIP address of self correspondence at cdma2000 1x network in MSC.
Below mainly realize method of the present invention with network architecture explanation shown in Figure 2.
Referring to shown in Figure 2, present embodiment is to increase interface between MSC in the cdma2000 1x network and the AN/PCF in the HRPD network, to be implemented in the beep-page message of transmitting cdma2000 1x in the HRPD network.After the user was provided with unconditional call forwarding and is voip call, when the user switched to cdma2000 1x network, voip call was to initiate on the packet domain of cdma2000 1x.
Referring to shown in Figure 3,, utilize unconditional branch to realize that the process of the inventive method is as follows based on network frame shown in Figure 2:
Step 301: be in the dual-mode terminal of the Idle state of HRPD network, the registration message to HRPD AN sends unconditional call forwarding wherein carries the VoIP number into self correspondence.
After step 302:HRPD AN receives the registration message of unconditional call forwarding, send unconditional call forwarding to MSC message is set, after the unconditional call forwarding that MSC receives this dual-mode terminal is provided with message, preserve the VoIP number of this dual-mode terminal, show that the user has activated call forwarding function this moment.
Step 303: after MSC received call request, MSC judged whether this user has activated call forwarding function, if activate, and execution in step 304, otherwise, jump out this flow process.Step 304:MSC obtains corresponding VoIP address according to the VoIP number of the transfer that the user is provided with from HLR, arrive corresponding voip gateway according to the VoIP addressing of address then, voip gateway is converted to the voip call of packet domain with the voice call of cdma2000 1x, realizes the ip voice business.If current VoIP/ video telephone (the VT)/press-and-talk delay sensitive type business such as (PTT) that has had the activation of HRPD network of terminal called, then terminal called returns Called Busy to cdma 1x, refuses this calling; Otherwise voip call is finished in the terminal ring.
Here, need preserve the corresponding relation of VoIP number and VoIP address in advance in HLR, MSC obtains corresponding VoIP address according to the VoIP number of the transfer that the user is provided with, and this is identical with addressing process in the cdma2000 1x network in the prior art.
Referring to shown in Figure 4,, utilize the condition calling transfer to realize that the detailed process of the inventive method is as follows based on network frame shown in Figure 2:
Step 401:MSC sends beep-page message by HRPD AN to dual-mode terminal.
Step 402: after terminal called is received this beep-page message, return page response to MSC by HRPD AN.
After step 403:MSC receives page response, issue calling number to terminal called by HRPD AN.
Step 404: after dual-mode terminal is received this calling number, the display of calling number, and judge user whether incoming call transfer instruction and VoIP number, if, this user's incoming call transfer instruction and VoIP number are sent to MSC, otherwise, jump out this flow process.
The forwarding number that step 405:MSC sets according to the user obtains corresponding VoIP address from HLR, arrive corresponding voip gateway according to the VoIP addressing of address then, voip gateway is converted to the voip call of packet domain with the voice call of cdma20001x, and then carries out the ip voice business in the HRPD network.If the current delay sensitive type business such as VoIP/VT/PTT that had the activation of HRPD network of terminal called, then terminal called returns Called Busy to cdma 1x, refuses this calling; Otherwise voip call is finished in the terminal ring.
Certainly, when the user was provided with calling transfer, the user also can import the destination number of other number as calling transfer.If the destination Mobile Station International ISDN Number of calling transfer is common number, what then will carry out after the MSC calling transfer is the ordinary call flow process, rather than the VoIP flow process.
And, when the user when cdma2000 1x/HRPD network switches, can pagedly arrive for guaranteeing the user, which network the user that knows that MSC must be real-time is in.Therefore, after the user is switched back cdma2000 1x network from the HRPD network, or after switching back the HRPD network from cdma2000 1x network, can initiatively initiate the location registers flow process by terminal.
Said method is that the existing network framework is changed, and realizes the ip voice business.Also can directly on existing network frame shown in Figure 1, realize the present invention.
Referring to shown in Figure 5, utilize in the existing network frame, realize that detailed process of the present invention is as follows:
Step 501: the dual-mode terminal that is in cdma2000 1x network, moving to the HRPD network coverage area, when preparation is switched to the HRPD network, and before leaving cdma2000 1x network, to the message that is provided with of MSC transmission unconditional call forwarding, the transfer destination number in the message parameter is the VoIP number of this machine;
After the unconditional call forwarding that step 502:MSC receives this user is provided with message, preserve this user's cdma2000 1x number and this user's VoIP number;
Step 503: this dual-mode terminal is carried out switching flow, finishes the switching of cdma2000 1x network to the HRPD net;
Step 504: after receiving the call request that contains called number as MSC, judge according to called number whether this user has activated call forwarding function, if, otherwise, jump out this flow process;
Corresponding VoIP address is obtained in the forwarding number addressing that step 505:MSC is provided with according to the user from HLR, arrive corresponding voip gateway according to the VoIP addressing of address then, voip gateway is converted to the voip call of packet domain with the voice call of cdma2000 1x, and then carries out the ip voice business in the HRPD network.Certainly, if the current delay sensitive type business such as VoIP/VT/PTT that had the activation of HRPD network of terminal called, then terminal called returns Called Busy to cdma2000 1x, refuses this calling; Otherwise voip call is finished in the terminal ring.
Need to prove, if utilize the network architecture of Fig. 1, realize in the method for the present invention, when the user when cdma2000 1x/HRPD network switches, for guaranteeing that the user can pagedly arrive, whether the dual-mode terminal user that knows that MSC must be real-time is in cdma2000 1x network, can consider to use the location registers flow process this moment, after the user is switched back cdma2000 1x network from the HRPD network, initiatively initiate registering flow path one time by terminal.And when the user when cdma2000 1x network switches to the HRPD network, owing to do not have interface between HRPDAN and the MSC, this moment, dual-mode terminal can not done the location registers operation, after dual-mode terminal leaves cdma2000 1x network, MSC can think when this terminal has switched to the HRPD network, and MSC can directly shift voip call for the HRPD net to the audio call of this dual-mode terminal with cdma2000 1x network.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
