Abstract
The present invention relates to a method for implementing dual-mode terminal communication in a radio communication system. The method mainly comprises the following steps: MSC sends a calling informing message carried with information of a calling number to an HRPD network; a dual-mode terminal positioned in the HRPD network obtains the information of the calling number; the dual-mode terminal determines whether the speech call is answered according to the information of the calling number and carries out corresponding processing operation. Therefore, according to the present invention, under the condition that the dual-mode terminal receives the calling informing message (which comprises the information of the calling number), service on the HRPD network does not need to be interrupted, and simultaneously, the information of the calling number is obtained in advance. A user can conveniently judge whether the speech call is answered according to the information of the calling number. If the user determines that the speech call is not answered, the service on the HRPD network is continued; when the user determines that a new incoming call is not answered, the whole processing procedure can not influence the service which is carried out on the HRPD network.
Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to the implementation method of dual-mode terminal communication in a kind of wireless communication system.
Background technology
According to the 3GPP2 standard as can be known, networking structure is relatively independent between cdma2000 and HRPD (HRPD (high rate packet data)) system, except can receiving same PDSN (data serving node), does not have the interface of other intercommunications between two network systems.Described cdma2000 1x system and HRPD Rev.0 system group network structure are as shown in Figure 1.
HRPD protocol definition voice are preferential, therefore, when terminal is carried out data service in the HRPD network, must be able to answer the voice paging from cdma2000 1x system.This just requires cdma2000 1x/HRPD dual-mode terminal when the HRPD network carries out data service, must forward the paging channel of cdma2000 1x network monitoring cdma2000 1x network according to the beep-page message timing cycle of 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.
If listened to cdma2000 1x voice paging message, then system can switch to and set up preceding reverse traffic channel in the cdma2000 1x system more unconditionally under the HRPD Dormant (HRPD sleep state) that switches to HRPD in the data service of HRPD grouping of network.Only after Traffic Channel was built up fully, network side was just given calling number come by Traffic Channel, and terminal just can point out the user to make the selection of whether answering cdma2000 1x voiceband telephone.
If the user selects not answer, terminal then can be from the HRPDDormant of cdma2000 1x switchback HRPD, then activating data service again.Because the switching time between cdma2000 1x and the HRPD net is long, require than higher data service for real-time, as VoIP (IP-based voice), Video Phone (video telephone), PTT (button is promptly logical), Streaming Media etc., in the process of switching, interrupt probably, have a strong impact on the use of user business.
That is to say, for cdma2000 and HRPD dual-mode terminal, when it resides in one of them network, in order to listen to beep-page message and system message from the another one network, the frequency at another network place be need regularly switch to according to the length in another ICQ cycle, beep-page message or system message monitored.Like this, make that dual-mode terminal is the information that guarantees two networks of reliable reception, need frequently switch search between two networks, this is for terminal, and power consumption is very big.
Simultaneously,, then can cause the discontinuous of business, influence view reception effect owing to frequent handover operation if the user listens to the BCMCS business in the HRPD system.
For addressing the above problem, the implementation of two kinds of dual-mode terminal communications is provided at present, will describe two kinds of implementations respectively below.
The first kind of implementation that adopts is at present: adopt the 1x/HRPD dual-mode terminal of two cover receivers, one cover transmitter, described dual-mode terminal can be answered the information in cdma2000 1x and two networks of HRPD simultaneously, but can only respond a network simultaneously.
As can be seen, in this scheme, when user terminal is commenced business in one network, can receive system message and beep-page message in another network reliably, thereby make that user terminal need not to switch continually between two networks for assurance reliable reception information again.
But, in this scheme, described dual-mode terminal is being carried out in the data service process on the HRPD network, if receive voice paging from cdma2000 1x system, then system can unconditionally switch to the data service of HRPD grouping of network under the HRPD Dormant, then, switch to the preceding reverse traffic channel of foundation in the cdma20001x system again.Only after Traffic Channel was built up fully, network side was just given calling number come by Traffic Channel.At this moment, terminal can point out the user to make the selection of whether answering cdma2000 1x voiceband telephone according to dialing number information.That is to say, no matter whether the user answers the voice call of cdma2000 1x system, the data service of HRPD network all will be interrupted, this just makes dual-mode terminal in communication process, for improving greatly than the possibility that higher business impacts by the more ongoing real-times of HRPD network.
In addition, this implementation also can increase the cost of user terminal, and this brings negative effect will for the popularization operation work of operator.
The second kind of implementation that adopts is at present: up-to-date HRPD standard network air interface has partly increased the message by HRPD forwarded cdma2000 1x at present, wherein can transmit beep-page message, short message, system message etc.Terrestrial interface has partly been introduced HRPD-1X and has been transmitted the mechanism of paging mutually, and corresponding network configuration as shown in Figure 2.Just between MSC (mobile exchange control unit) and HRPD AN (HRPD Access Network), increase the equipment of an IWS (interworking unit), transmit paging separately.
This scheme is adapted to the CDMA2000 1X and the HRPD dual-mode terminal of single-receiver.Be used to solve terminal and when the BCMCS that monitors the HRPD network is professional, need not frequently to switch to cdma2000 1X and go to listen to paging, expand to afterwards at cdma2000 1X network and receive the paging that also can receive when professional from the HRPD network.
The basic principle of scheme is that the AN of HRPD is managed as the BSC (base station controller) of cdma2000 1X, MSC safeguards the lane place of two networks simultaneously, and terminal is resident need pass through Iocation Update (position renewals) message when the HRPD network and arrive the MSC district and register.
Though this programme need not to change MSC and the BSC of cdma2000 1X, get final product and only the AN of HRPD is made amendment.But corresponding forwarding capability has only solved the cdma2000 1x/HRPD dual-mode terminal at single-receiver, single transmit machine, the problem that must frequently search between two networks for the beep-page message that receives cdma2000 1x network.
No matter for terminal is at the HRPD network or in cdma2000 1X network, if receive from can switching in another network at once after the paging of another network and initiate page response, this will cause the interruption of current business, do not receive the paging of another network during the business of perhaps can only being arranged to is simply carried out, this set can bring the decline of user experience equally.
The third implementation that adopts is at present: after MSC receives the call information of 1X, send two message by AN to MS: send Paging Request message earlier, send FeatureNotification message then, wherein calling number is included in the Feature Notification message at once.MSC sends Paging Request message to the 1X access network simultaneously.After MS receives Paging Request message, start timer and wait for follow-up Feature Notification message, after MS receives FeatureNotification message, then receive this message to the HRPD network validation, MS judges whether to answer according to the calling number that comprises in this message then.If MS selects to answer then returns page response to the 1X network.If the timer expiry among the MS then no longer wait for Feature Notification message directly returns page response to the 1X network.
This scheme is adapted to the CDMA2000 1X and the HRPD dual-mode terminal of single-receiver.Being used to solve terminal need not frequently to switch to cdma2000 1X and goes to listen to paging when monitoring the HRPD network.
The shortcoming of this scheme is that terminal need be handled two message, and connecting time is long, handles more complicated.Reliability is also lower.
In a word, the appropriate technical solution that prior art provides has only solved the problem of frequent search between the network, but shortcoming is separately all arranged.Improve to solve under the unbroken situation of current service of user terminal the implementation of selecting flexibly according to the significance level of data service and speech business.

Embodiment
What the present invention mainly solved is after terminal receives the cdma2000 1x call notification message of HRPD net forwarding at HRPD, can know the dialing number information that makes a call in advance, and under the data service prerequisite of not interrupting on the current HRPD network, determine whether to answer new calling according to described dialing number information by user terminal.
Core of the present invention is, in cdma2000 1x system and HRPD system group network, when other customer call dual-mode terminals, then at first directly dialing number information is notified corresponding dual-mode terminal by the HRPD network, and whether determine incoming call answering according to the dialing number information of knowing, thereby improve the reliability of dual-mode terminal communication by this dual-mode terminal user.
CDMA2000 1X system described in the present invention comprises: CDMA and CDMA2000 1X/CDMA2000 1X EVDV (strengthening data-voice mixes) system.
For the present invention there being further understanding, be described further below in conjunction with the specific implementation of accompanying drawing to method of the present invention.
, like this, dual-mode terminal also just need not frequently to switch in the cdma2000 1x network, can hear the call notification message from cdma2000 1X system when the HRPD network carries out business, and can obtain calling number.
For the forwarding that realizes call notification message in the HRPD network is handled, then need between MSC and HRPD AN, increase the IWS entity, in the MSC side, regard HRPD AN as alien frequencies cdma20001x BSS (BSS, base station system) managed together, the call notification message of cdma2000 1x can be handed down to dual-mode terminal through the HRPD network by the A1 interface.
Above-mentioned technical description is realized in the prior art, the objective of the invention is to improve at the above-mentioned state of the art, so that dual-mode terminal is hearing from cdma2000 1x call notification more reliably with simple.
In order to make dual-mode terminal just can judge whether to answer this calling in advance in the HRPD network, user terminal need be known the user's who makes a call identity information, i.e. calling number in advance.Like this, if this dual-mode terminal determines to answer the voice of incoming call according to dialing number information, then handle according to handling process of the prior art, promptly dual-mode terminal switches to cdma2000 1x network, answers this voice; If dual-mode terminal selects not answer these voice, then can directly refuse this audio call not interrupting current HRPD Network simultaneously by the HRPD network.
The invention provides a kind of method of utilizing existing message to transmit calling number in advance, make terminal after the HRPD network receives cdma2000 1x call notification message, can directly know dialing number information, and needn't switch to cdma2000 1x system.The user can select whether to answer this audio call according to number after learning calling number.Below in conjunction with Fig. 3 the specific implementation of the method for the invention is described, as shown in Figure 3, specifically may further comprise the steps:
Step 31:MSC receives an audio call, and when calling out the dual-mode terminal in the HRPD network, then MSC sends a Paging Request message according to the lane place to HRPD PCF/AN.When receiving, HRPD PCF/AN starts timer after MSC sends Paging Request message.
Step 32:MSC is specially according to the BS of lane place all cdma2000 1X in the lane place (being BSS) and sends Paging Request message, need not comprise calling number in this message;
Be performing step 31 and step 32, at first the location area information of dual-mode terminal in cdma network and HRPD network need preserved on the MSC, with and belonging network information, MSC just can distinguish out corresponding AN or BSS like this, and sends the corresponding call notification message;
Can determine when transmission link is set up that by modes such as signalling point, register flow path, lane place divisions this access control function entity is the sign of HRPD AN/PCF on the MSC, thereby active zone is told BSS or AN on MSC.
Step 33:MSC sends the FeatureNotification message that comprises calling number to HRPD PCF/AN.
Step 34: if the Feature Notification message that has dialing number information that HRPD PCF/AN receives before above-mentioned timer expiry, then:
When IWS or AN comprise more than 2 concrete message for call notification message, preferentially use a 3G1XServices packet (service packet among the 3G1X) message bearing,, reduce the flow processing complexity to increase reliability.
If the unreceived Feature Notification message that has dialing number information before timer expiry, then only send 3G1XServices packet (service packet among the 3G1X) message that comprises Paging Request message and arrive MS/AT (user terminal, be dual-mode terminal) so that dual-mode terminal obtains dialing number information;
Be specially: after HRPD PCF/AN receives the message that has dialing number information that MSC sends, then inquire about IMSI (international mobile subscriber identification) the information record of preserving, and handle according to Query Result: (1) is not if inquire user's IMSI record, then flow process finishes, simultaneously, if MSC fails to receive call notification message response and relevant terminal rejection information from two networks, then send subscriber absent message to the calling subscriber behind timer expiry; (2) if inquire user's IMSI record, judge at first whether the user is in connected state: (21) if send at connected state then by forward traffic channel comprise calling number call notification message to MS/AT, (22) if the user is in Idle state (Idle state of HRPD) by the forward direction synchronization control channel send comprise the calling number call notification message 3G1XServices packet message to MS/AT;
Step 31 of the present invention to step 33 can also adopt following dual mode to realize:
First kind of mode is:
Preserve the current state information of dual-mode terminal on MSC, described state comprises Packet Service activated state and Idle state; For the state that guarantees dual-mode terminal need be when its state changes for its current state, to the current state of MSC circular, being specially when becoming activated state by Idle state needs circular, also needs when becoming Idle state by activated state to circulate a notice of;
When needs sent data service, MSC determined according to the state information whether called subscriber's (being dual-mode terminal) who preserves is in activated state whether the data service that sends carries calling number; If be activated state, then MSC needs to carry calling number in the data service that interworking unit IWS sends, otherwise, need not to carry calling number.
The second way is:
Preserve the state information of dual-mode terminal on IWS, same, described state comprises: activated state and Idle state, and when the dual-mode terminal state changes, need circulate a notice of current state to IWS;
When needs send corresponding data service, IWS determines whether carry calling number in the data service of issuing access control function entity AN/PCF according to User Status, if dual-mode terminal is in activated state, then carries calling number in described data service, otherwise, do not carry calling number.
In the second way, IWS is after the data service that receives from MSC, also can be (at this moment to the state of AN/PCF inquiring user, state of user information no longer needs to be stored on the IWS), if the user is in activated state, then in the data service that sends to access control function entity AN/PCF, carry calling number,, then need not carry calling number if be in Idle state.
Certainly, among the present invention, also can be indifferent to it and whether be in state of activation, and directly carry out follow-up processing procedure, will subsequent processes be elaborated below;
Step 35: receive the 3G1XServices packet message of HRPD BS as MS/AT after, 3G1X Services packet message is analyzed, if comprise Feature Notification message in this message, then MS/AT sends response message to the HRPD network.
Step 36: then HRPD PCF/AN transmits the response message that receives to MSC.After MSC receives this response message, stop to send beep-page message to 1X Access Network and HRPD network.
Step 37:MS analyzes Feature Notification message, if carry calling number in the message, then whether answer the calling of cdma2000 1X system according to the calling number decision of carrying in the message, if answer then send to discharge the message that HRPD connects to HRPD PCF/AN, HRPDPCF/AN will discharge corresponding HRPD connection after receiving the message that described release HRPD connects; If MS/AT receives the 3G1XServices packet message of HRPD BS and does not carry effective calling number, then directly send to HRPD PCF/AN and discharge the message that HRPD connects, HRPD PCF/AN will discharge corresponding HRPD connection after receiving the message that described release HRPD connects; When the MS/AT decision switches to the call accepted of 1X system, then MS/AT returns cdma2000 1X system, and give cdma2000 1x BS to returning page-response message Page Response message at access channel, this message is used to reply the paging from HRPD PCF/AN.
Step 38:cdma2000 1x BS constructs Paging Response message and puts into three layers of complete informational message Complete Layer 3 Information message and sends to MSC;
If carry Tag IE (message field label) in the message, cdma2000 1x BS should comprise this IE (message field);
The registration of cdma2000 1X system will be accomplished to by corresponding processing procedure MS, and the called flow process of setting up of follow-up cdma2000 1X can be carried out.
Method of the present invention is in the specific implementation process, receive the 3G1XServices packet message of HRPD BS as MS/AT after, if corresponding call is not answered in decision, then need to return refusal order Reject Order message to HRPDPCF/AN, carry cause value in the message;
Described cause value can specifically can be provided with according to user's actual needs flexibly for busy cause value of user or other reasons value;
Terminal is after the HRPD network returns refuse information, and access control function entity no longer sends refuse information to MSC, and shields the call notification message that MSC retransmits automatically, for this reason, needs to carry the repeating transmission indication information in the call notification message that described MSC retransmits.
Certainly, also can not callback cry response for this situation, direct end process flow process, but like this, on MSC, when timer expiry,, thereby need terminal after receiving paging next time, to continue decision whether to answer if do not receive after call and the rejection message then can retransmit beep-page message three times.After the refusal that HRPD PCF/AN receives MS/AT is answered message, then construct paging refuse information Paging Reject message and send to MSC.In the reason Cause of message field, fill in Reason For Denial according to the cause value in the Reject Order message, after MSC receives, send busy message of user or the other reasons calling subscriber in the cdma2000 1x system, so that the calling subscriber obtains corresponding reason.
Among the present invention, the Feature Notification message that is sent to HRPD PCF/AN by MSC can include only following main contents, to reduce expense:
User ID, calling number.
After the user receives call notification message, can know dialing number information, and can judge whether that directly needs answer this audio call according to dialing number information, if do not answer, can directly refuse this calling by the HRPD network.
In the method for the present invention, MSC is in order to send cdma2000 1x call notification message by the HRPD network, must manage the location area information of cdma2000 1x system and HRPD system simultaneously, and foundation mapping table between the two, the location area information that promptly needs to preserve AN/PCF in the HRPD network.Simultaneously, in the static configuration data of MSC, also need to point out respectively in the signalling point of the BSC that is attached thereto and AN, which is BSC, which is AN, like this, can be so that the beep-page message that sends to BSC need be with calling number, consistent to guarantee it with existing procedure.
Among the present invention, dual-mode terminal resident (Idle state) will carry out the position at MSC and upgrade at the HRPD network.So that when transmitting cdma2000 1x call notification message, carry correct cdma2000 1x location area information.Described dual-mode terminal activated state also wants regularly to carry out at MSC the position renewal of CDMA2000 1X at the HRPD network, and MSC specifically can upgrade the location area information of dual-mode terminal by the position corresponding relation between HRPD and the CDMA; MSC can keep the old CDMA lane place of terminal to report when increasing the CDMA lane place corresponding with the HRPD lane place, to avoid losing of cdma lane place.Described dual-mode terminal activated state then can be carried out the position renewal of HRPD to the interface of IWS by existing MSC at cdma network, to reduce the frequency that dual-mode terminal switches between two nets, reaches the effect of power saving.
In sum, among the present invention, after dual-mode terminal receives call notification message, can in the business on not interrupting the HRPD network, know calling number in advance,, effectively improve the reliability of dual-mode terminal communication to judge whether to answer these voice.
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.
