CN101166370A - Inter-packet-node paging between communication networks - Google Patents

Abstract

A system and method is disclosed to provide inter-packet-node paging between communication networks. The networks recognize whether inter-network paging is supported therebetween and advertise overlapping codes between networks having adjacent location areas. When the mobile station moves from the first network to the second network, the first network determines whether the second network shares an overlapping code therewith. If the networks share an overlapping code, the first network sends a paging request to the second network including link configuration information and the notification for the mobile station, wherein the notification can be delivered to mobile station in the second location area of the second communication network without the mobile station having to register in the second communication network.

Description

Inter-packet-node paging between the communication network

Technical field

The present invention relates generally to field of wireless communications, more specifically, relate to the paging between the communication network.

Background technology

Third generation cooperative programme two (3GGP2) code division multiple access (CDMA) the network support grouped data and the both circuit-switched voice communication that are called as 3GGP2 cdma2000.System supports packet data originally and both circuit-switched voice communication, and be commonly called cdma2000 1X system.The air interface of cdma2000 1X system is carried out standardization at 3GPP2 file C.S0001 in C.S0005 and among the corresponding standard TIA-2000 of telecommunications industry association (TIA).In addition, created new packet data standard, for example cdma2000 HRPD (high rate packet data) (cdma2000HRPD).Cdma2000 HRPD air interface is carried out standardization in 3GPP2 file C.S0024-B.In order to guarantee mobile radio communication apparatus continuity when mobile between network that covers 1x and packet data network, expectation can provide cross-paged (cross-paging) function, it makes when travelling carriage is worked on the HRPD network, notifies 1x circuit voice call or short message service (SMS) message that enters to mobile unit.

Support the 3GGP2 Radio Access Network (RAN) of cross-paged to comprise mobile switching centre (MSC), 1x BS (base station), HRPD AN (access network or access node), HRPDPCF and packet data serving node (PDSN), and carry out standardization with two different RAN structures in the A.S0009-B (see figure 2) for 3GGP2 A.S0008-B (see figure 1).In 3GPP2, introduce interconnected systems (IWS) function, be used for the HRPD system is connected with the 1X system.

In addition, 3GPP2 C.S0024-A supports secondary colour coding, and wherein HRPD AN broadcasting is by the colour coding of contiguous AN use.The use of secondary colour coding makes the travelling carriage of dormancy move between the sub-network of AN/PCF, and these sub-networks do not need to carry out registration and propagate overlapping colour coding.Advise, allow the contiguous AN/PCF of AN/PCF request represent it to send paging, i.e. paging between AN.But when using between AN paging when supporting (or open secondary colour coding), the cross-paged from the 1x system to the HRPD system can be failed.Because travelling carriage is not carried out registration in new sub-network, then the 1x system will use source network to carry out cross-paged.Because travelling carriage is in the new sub-network, this will make cross-paged fail.In addition, because existing technology does not transmit session information to target AN, so paging can not be carried out between existing AN.

A solution that proposes is all to send the cross-paged request to two AN/PCF, i.e. first of mobile station login (source) sub-network and its second (target) sub-network that moves to.But this proposal can not realize, because the Circuit Service notice of having only the AN/PCF of first sub-network to have to be used for travelling carriage is used (CSNA) configuration.The AN/PCF of second sub-network does not have the CSNA configuration that is used for travelling carriage.Therefore, the CSNA state among the AN/PCF of second sub-network is " unactivated state ", and this has stoped to travelling carriage and sends any CSNA message.

Another solution that proposes is to use paging between existing AN.This proposes to use paging mechanism between existing AN, and promptly source AN/PCF comes to send paging request message to target AN/PCF, and target AN/PCF sends the HRPD beep-page message to travelling carriage then.But current HRPD beep-page message does not comprise cross-paged information.Therefore, when travelling carriage paging receiving message, will begin normal procedure, and promptly set up with the session of target AN/PCF, carry out the session transmission and carry out the 1x registration then.Registration needs the time.In addition, the cross-paged transmission may restart in the 1x system.But this needs several seconds time, knows that up to the 1x system travelling carriage is arranged in the targeted subnet network, and this may make that the 1x paging is overtime.As a result, the solution of current proposition can not solve the above problems.

Need a kind of new technology that paging between AN is provided now.More specifically, preferably provide page procedure between a kind of AN of expansion to support the cross-paged from 1x to HRPD among the adjacent AN, travelling carriage reduces the number of registration simultaneously.

Embodiment

The new technology of paging between a kind of AN of providing has been provided in the present invention.More specifically, the invention provides page procedure between a kind of AN of expansion and support the cross-paged from 1x to HRPD among the adjacent AN, enable secondary colour coding simultaneously, make travelling carriage reduce the number of registration.Particularly, introduced a kind of improved paging request, between sub-network, when mobile, can realize cross-paged to guarantee travelling carriage when dormancy.In addition, the invention provides between a kind of AN of expansion page procedure and come in adjacent AN, to transmit HRPD paging and DataOverSignaling.

In actual applications, have double mode cdma2000 travelling carriage (MS) or access terminal (AT), it can be supported and the communicating by letter of cdma2000 1X circuit-switched network and HRPD (high rate packet data) (HRPD) network.Double mode travelling carriage or access terminal and be also referred to as hybrid access terminal or HAT.One or more AN are connected to PCF, and the feasible transmission that can carry out packet between MS and group data service node (PDSN), and this PDSN is connected to the other network of access network outside, for example internet.The grouping data conversation of MS may be in dormancy or active state.

When Traffic Channel, A8 and A10 carrying source are assigned to MS, when carrying out the packet data transmission between PDSN and the MS, the grouping data conversation of MS considered to be in active state.

When UATI and A10 carrying source are assigned to MS, but when not having Traffic Channel or A8 carrying source to be assigned to MS, the grouping data conversation of MS considered to be in resting state.When grouping data conversation is in resting state, not or have low volume data to exchange, still, this session can not activated soon again between MS and PSDN, promptly when new data need be when MS or PDSN send, the grouping data conversation of MS changes active state into.

As used herein, MS can be the subscriber equipment of any communication equipment or radio communication.MS can comprise the communication equipment of any kind, comprises radio telephone, personal digital assistant, computer, cordless telephone etc.As described here, describing context environmental of the present invention is the Wireless Telecom Equipment of supporting the cdma2000 standard, and this standard comprises cdma2000 1X and HRPD air-interface standard.But, should be understood that the present invention also can be used in the equipment of supporting various other air-interface standards, for example, IEEE 802.11 or IEEE 802.16 (WiMAX), and the description here only illustrates by example.

As used herein, ios interface parameter and definition below having used:

The A1/A1p interface transmits MSC/MSCe and the calling control of BS (BSC) or IWS assembly and the signal message between the mobile management function.

The A2 interface is used to provide the passage of customer service.The A2 interface transmits 64/56kbps PCM information (being used for the voice towards circuit) between the choosing of the switch component of MSC and BS/Dispatching Unit (SDU) or the unrestricted digital information (UDI is used for ISDN) of 64kbps.

The A8 interface transmits the customer service between HRPD AN and the Packet Control Function (PCF).

The A9 interface transmits the signaling information between HRPD AN and the PCF.

The A10 interface transmits the customer service between PCF and the PDSN.

The A11 interface transmits the signaling information between PCF and the PDSN.

The signaling information relevant between SC/MM function among A12 interface transmission AN or the PCF and the AN-AAA (access network authentication, authorization and accounting main body) with terminal authentication.

The SC/MM function of A13 interface transfer source packet data node (AN or PCF that the HRPD architecture is supported) and the signaling information between the SC/MM function in the targeted packets back end (AN or PCF).

Signaling information (only being used for A.S0009) between the SC/MM function of A14 interface transmission PCF and AN.

When HRPD PCF supported between AN paging, the A15 interface transmitted the signaling information (only being used for A.S0009) between the AN.

The transmission of A16 interface is used for the source AN of connection status session transfer (direct-cut operation) between HRPD AN and the signaling information between the target AN.

Signaling information between A17 interface transfer source AN and the target AN is supported connect between AN (soft/More Soft Handoff) with management resource.

The A18 interface is the customer service that is used for AT (being the air interface traffic channel data) between transfer source AN and the target RT during connecting.

The relevant control messages that connects of carrying that the RT that is used for AT between A19 interface transfer source AN and the target RT is specific.

Customer service (only being used for A.S0009) between the SC/MM function of A20 interface transmission PCF and AN.

The A21 interface transmits the signaling information between HRPD AN/PCF and the IWS.

HAT is the double mode cdma2000 travelling carriage that can support 1x and HRPD air-interface standard (3GGP2C.S0001-C.S0005, C.S0024, C.S0075 and C.S0082).

Source AC/PCF connects the HRPD AN/PCF that is connected to PDSN by A10, is used for supporting the HAT grouping data conversation of HRPD network.

Target AN/PCF is the HRPDAN/PCF that serves HAT as HAT when source AN/PCF moves.Source AN/PCF and different packet zone or the sub-networks of target AN/PCF control here are used interchangeably.In the present invention, the overlapping colour coding of source AN/PCF and target AN/PCF propaganda.

MSC is 1X MSC, and wherein the HAT registration is used for Circuit Service (travelling carriage is positioned at this MSC band of position).

Should be noted that in current 3GPP2 HRPD architecture, the configurable SC/MM that has among AN (A.S0008 standard) or the PCF (A.S0009 standard) of interconnected solution (IWS), or dispose 1x BS, or as single entities.

With reference to figure 3, as used herein, MS 10 also can be called as subscriber equipment (UE) or access terminal (AT).In cdma2000 1X system, to come for the geographic area provides service by mobile switching centre (MSC), this center provides service by the 1x BS that is connected with MSC 24 for its oneself the 1x band of position 22.High-speed grouped data network covers cdma2000 1X network by sub-network (or packet zone).Each sub-network or packet zone provide service by Packet Control Function (PCF) and one or more access network (AN).Each sub-network illustrates the single AN that disposes PCF, but each PCF also can support a plurality of AN, and all are all in PCF sub-network or packet zone boundaries.Subnet boundaries or packet zone provide service by a PCF.For example, AN1 node 12 provides Packet data service for sub-network 118, and AN2 node 14 provides Packet data service for sub-network 220.

Source AN/PCF 12 is HRPD AN/PCF (AN/PCF1) that the grouping data conversation of travelling carriage is labeled, and promptly has with the A10/A11 interface of PDSN (not shown) to be connected, and it supports the grouping data conversation of the MS in the HRPD network.Target AN/PCF (AN/PCF2) 14 service second packet zone or sub-networks 20.Usually, along with MS moves between source AN/PCF and target AN/PCF, need dormancy to switch and registration.

MSC is 1X MSC, and wherein MS 10 registrations are used for circuit-switched service (travelling carriage is positioned at the band of position, MSC ground 22).

With reference to figure 4,3GPP2 C.S0024-A and C.S0024-B support secondary colour coding, and wherein AN broadcasting is by the colour coding of adjacent AN use.The use of secondary colour coding makes the travelling carriage of dormancy to move between sub-network, the overlapping colour coding of these sub-network propagandas, and do not need to carry out registration.The propaganda of secondary color code value may need access network that paging is conveyed through subnet boundaries, enters other sub-networks with same color value, and this same color value is propagated in the secondary color code value.

For example, in Fig. 4, when travelling carriage moves to sub-network 2 (under the AN/PCF2) from sub-network 1 (under the AN/PCF1), travelling carriage does not need to carry out the HRPD registration, and (promptly 1) is identical with the colour coding of sub-network 1 because the secondary colour coding of sub-network 2.Therefore, AN/PCF1 can require adjacent AN/PCF2 to represent it oneself to transmit paging to travelling carriage, i.e. paging between AN.Simultaneously, if travelling carriage does not change the 1x registration area, then travelling carriage is not carried out the 1x registration by the HRPD system yet.As a result, the 1x system will still have the cross-paged association of pointing to AN/PCF1.Similarly, if travelling carriage registration in sub-network 2 originally and moves to sub-network 1 (under the AN1), then travelling carriage does not need to carry out the HRPD registration, and (promptly 2) is identical with the colour coding of the sub-network 2 that service is provided because the secondary colour coding of sub-network 1.Simultaneously, if travelling carriage does not change the 1x registration area, then travelling carriage is not carried out the 1x registration by the HRPD system yet.As a result, the 1x system will still have the cross-paged association of pointing to AN/PCF2.

Should be noted that similar notion also used by HRPD Rev.C (stages 2 reform air interface specification), it has defined main region and secondary region, and mass-tone sign indicating number and secondary colour coding among this and the above-mentioned HRPD Rev.A are similar.

Under any circumstance, the use of mass-tone sign indicating number and secondary colour coding (or zone) can make the cross-paged from 1x to HRPD have problems.Refer again to Fig. 3,1x system (be used for the MSC based on the cross-paged of A1/A1p, or be used for the 1x BS1 based on the cross-paged of A21) has the cross-paged association of pointing to the AN/PCF1 12 that is used for travelling carriage 10.In the HRPD system, travelling carriage is in resting state, and moves to position B (sub-network 2) from position A (sub-network 1).Because two sub-networks are all propagated overlapping colour coding (as shown in Figure 4), then travelling carriage is not carried out registration at position B, because suppose its registration in sub-network 1 before.When cross-paged (can be the 1x paging promptly, or end at the SMS of portable terminal) that need be from 1x to HRPD, 1x MSC (or 1x BS1) sends the paging request to AN/PCF1.But because travelling carriage is arranged in sub-network 2, the paging in the sub-network 1 will be failed.In addition, for paging between the AN of routine, target AN need know some required attributes, with successful mobile paging station.These attributes comprise, PreferredConralChannelCycle for example, SlottedMode, PagingMask and QuickPaging etc.This problem also exists for HRPD Rev.C, because Rev.C uses the idea similar to secondary colour coding.As a result, need a solution when using between AN paging, to support the cross-paged of 1x, and support paging between conventional AN to HRPD.In the following discussion, the 1x paging transmits and is used as the cross-paged example, so 1x message is the paging request.Should be noted that this also can be used for the cross-paged of other 1x to HRPD, for example, in the 1x system, use the SMS that ends at travelling carriage of ADDS beep-page message to transmit.

A possible solution is to make the 1x system all send the paging request to two AN/PCF.But this solution can not realize, because have only AN/PCF1 to have to be used for the CSNA configuration of travelling carriage.AN/PCF2 does not have the CSNA configuration that is used for travelling carriage.CSNA state among the AN/PCF2 is " inactive state ", and this has stoped to travelling carriage and sends any CSNA message.

Another possible solution is to use paging mechanism between existing AN.When AN/PCF2 paging receiving request message, AN/PCF2 sends the HRPD beep-page message to travelling carriage.But this solution can not realize, because current HRPD beep-page message does not comprise cross-paged information.Therefore, when travelling carriage paging receiving message, will open normal procedure, and promptly set up with session, the execution session of AN/PCF2 and shift, and carry out the 1x registration then.Travelling carriage was carried out the 1x registration in sub-network 2 after, the 1x system can restart cross-paged and transmit.But this need take several seconds time, may cause the 1x paging overtime.

Another possible solution is that increase page response and page response acknowledge message are right, make target AN notification source AN: target AN has obtained MS/AT, and when source AN knows that himself or target AN obtain MS/AT, it is right to increase event notice and event notice acknowledge message, saves the paging resource.But this solution does not consider that session information arrives the transmission of target AN/PCF, does not have to consider the support to the DO cross-paged to 1x yet.Therefore, above-mentioned solution all can not solve the above problems.

The present invention supports 1x among the adjacent AN to the HRPD cross-paged by page procedure between the AN of expansion, thereby has solved top problem.Particularly, provide the message of revising, it comprises new signaling information.An innovation aspect of the present invention is to have beep-page message between improved AN, and it comprises the session state information record (SSIR) of the CSNA that allows adjacent AN/PCF to set up travelling carriage.Session information record (SSIR) also can be supported paging between conventional AN and be used to end at the DataOverSignaling transmission of travelling carriage.Another innovation aspect of the present invention is to have beep-page message between AN, it comprises encapsulation HRPD message, this message transmits and is used for the 3G1xServices message of 1x to the HRPD cross-paged, or is used for the DataOverSignaling message of HRPDDataOverSignaling.Another innovation aspect of the present invention is to have paging refuse information between AN, and this message allows travelling carriage by adjacent AN/PCF refusal 1x paging.Another innovation aspect of the present invention is to have paging between AN " to transmit " message, and it successfully sends travelling carriage to the SMS that the indication of 1x system ends at travelling carriage.Another innovation aspect of the present invention is to have paging between AN " to transmit " signaling message, and it is successfully sent to travelling carriage to the HRPD DataOverSignaling that AN/PCF indication in source ends at travelling carriage.To tell about these aspects in detail below.

With reference to figure 5, the call flow of travelling carriage paging between the conventional AN between communication network or the sub-network of dormancy is described according to the present invention.Source AN/PCF and the overlapping colour coding of target AN/PCF propaganda.In step a), travelling carriage is registered in the AN/PCF of source.Travelling carriage is arranged in borderline region, the sector among the paging domain coverage goal AN/PCF.In step b), PDSN sends packet data to source AN/PCF.In step c), source AN/PCF need to judge whether the travelling carriage in the adjacent sub-network of paging.Source AN/PCF sends the Axx paging request message to target AN/PCF.As used herein, Axx is meant any appropriate interface that is used to send paging request message.According to the present invention, the Axx paging request message comprises session state information record (SSIR), and target AN/PCF can suitably send beep-page message to travelling carriage (UE1) like this.In step d), based on the information that receives in the Axx paging request message, source AN/PCF and target AN/PCF send beep-page message to AT simultaneously on control channel.AT is from target AN/PCF paging receiving message for this call flow hypothesis.If AT receives beep-page message from target AN/PCF, then AT inserts by source AN/PCF.In step e), travelling carriage is set up the session with target AN/PCF, and carries out the dormancy switching.

With reference to figure 6,, wherein have the DataOverSignaling (DOS) that ends at travelling carriage and transmit according to the call flow that the invention describes the paging between the conventional AN between communication network or the sub-network of dormancy mobile radio station.Source AN/PCF and the overlapping colour coding of target AN/PCF propaganda.In step a), travelling carriage is registered in the AN/PCF of source.Travelling carriage is arranged in borderline region, the sector among the paging domain coverage goal AN/PCF.In step b), PDSN sends packet data to source AN/PCF.The PCF decision uses DataOverSignaling (DOS) to send packet data to travelling carriage.In step c), source AN/PCF judges whether need to send the travelling carriage of DOS in the adjacent sub-network.Source AN/PCF sends the Axx paging request message to target AN/PCF.According to the present invention, the Axx paging request message comprises session state information record (SSIR), target AN/PCF can suitably send DataOverSignaling message to travelling carriage (UE1) like this, and is the same with DataOverSignaling message encapsulation HRPD message.In step d), based on the information that receives in the Axx paging request message, source AN/PCF and target AN/PCF send DataOverSignaling message to AT simultaneously on control channel.This call flow hypothesis AT receives DataOverSignaling message from target AN/PCF.If AT receives DataOverSignaling message from source AN/PCF, then AT inserts by source AN/PCF.In step e), when travelling carriage received DataOverSignaling message, travelling carriage sent DataOverSignaling message to target AN/PCF.In step f), target AN/PCF sends the Axx paging that comprises encapsulation HRPD message to source AN/PCF and transmits message, to confirm that DOS successfully is sent to travelling carriage.Encapsulation HRPD message is HRPDDataOverSignalingAck message.

With reference to figure 7, the call flow of resting state paging between the AN of travelling carriage has been described according to of the present invention when source AN/PCF wants paging to belong to AT in the sector of target AN/PCF.It is noted that this call flow also can be used for being used for transmitting based on the short message service that ends at travelling carriage (SMS) message of the HRPD communication network of A.S0008.Source AN/PCF and the overlapping colour coding of target AN/PCF propaganda.In step a), travelling carriage is registered in the AN/PCF of source.Travelling carriage is arranged in borderline region, the sector among the paging domain coverage goal AN/PCF.In step b), the 1x system judges that entering calling ends at the interior MS/AT of its service area.The 1x system sends the paging request to source AN, and (note: if IWS is configured in (is PCF for A.S0009) in the AN for A.S0008, this can be the A1 paging request message; If perhaps IWS is configured in the 1x BS or is configured to single entities, this can be an A21-1x air interface signaling message).In step c), source AN/PCF judges the travelling carriage that needs in the adjacent sub-network of paging.Source AN/PCF sends the Axx paging request message to target AN/PCF.According to the present invention, the Axx paging request message comprises session state information record (SSIR) and encapsulation HRPD message.The HRPD message of encapsulation comprises 3G1xServices message.In step d), based on the information that receives in the Axx paging request message, source AN/PCF and target AN/PCF send 3G1xServices message to AT simultaneously on control channel.This call flow hypothesis AT receives 3G1xServices message from target AN/PCF.If AT receives 3G1xServices message from source AN/PCF, then AT inserts by source AN/PCF.In step e), this calling example hypothesis user refuses the 1x paging.Travelling carriage sends the 1x release command that is encapsulated in the HRPD CSNA message and refuses the 1x paging.In step f), target AN/PCF sends Axx paging refuse information to source AN/PCF.According to the present invention, this message comprises the HRPD message of encapsulation.In this step, the HRPD message of encapsulation comprises 3G1xServices message, and it is packaged with the release command message that receives from travelling carriage by CSNA.In step g), source AN/PCF submits to the 1x system with refuse information.

When this call flow was used for the short message service that ends at travelling carriage (SMS) based on the HRPD communication network of A.S0008 and transmits, the 1x system transmit a request to source AN/PCF in step b.This request is the ADDS beep-page message when IWS is configured among the HRPD AN, perhaps is A21-1x air interface signaling message when IWS is configured among the 1x BS or is configured to single entities.In step c, the HRPD message of encapsulation comprises 3G1 xServices message, and it is packaged with the 1x data burst message.

With reference to figure 8, described for A.S0009, when source AN/PCF wants paging to belong to AT in the sector of target P CF, have the call flow of resting state paging between the AN that the SMS that ends at travelling carriage transmits.In step a), source AN/PCF and the overlapping colour coding of target AN/PCF propaganda.Travelling carriage is registered in the AN/PCF of source.AT registers at boundary sector, and paging domain covers the sector that belongs to target AN like this.This may be because based on the paging of distance or use the sub-network hysteresis of secondary colour coding.In step b), after source AN registration, source AN sends the general updating message of A14 that comprises sector ID to source PCF, and the device Tgu14 that picks up counting at AT.In step c), the current location of source PCF registration AT, and send general renewal of A14 and finish message, with the general updating message of response A14.Then, source AN stops timer Tgu14.In step d), the 1x system judges that point-to-point short message is sent to MS/AT.The 1x system sends message to source PCF, and (note: this can be the A1-ADDS beep-page message in the PCF if IWS is configured in; If IWS is configured in the 1x BS or during for single entities, this can be an A21-1x air interface signaling message).In step e), source PCF sends A14-1x service paging message to AN, and opens timer T1xsp14.This message comprises treats the general beep-page message that sends aloft.In step f), AN sends A14-1x service paging acknowledge message to PCF.PCF stops timer T1xsp14 then.

In step g), source PCF judges that paging domain also comprises some wireless transceiver among the target AN.Source PCF sends the Axx paging request message to target P CF, and opens timer Tpreqack-xx.According to the present invention, the Axx paging request message comprises the HRPD message of SSIR and encapsulation, and SSIR comprises for example CSNA attribute.In this step, the HRPD message of encapsulation comprises 3G1xServices message, and this message has encapsulated the 1x data burst message.At step h) in, target P CF sends Axx paging request acknowledge message and gets back to source PCF.When receiving Axx paging request acknowledge message, source PCF stops timer Tpreqack-xx.In step I) in, target P CF sends A14-1x service paging message to AN, and opens timer T1xsp14.At step j) in, AN sends A14-1x service paging acknowledge message to PCF.PCF stops timer T1xsp14.At step k) in, based on the information that receives in the Axx paging request message, source AN and target AN send 3G1xServices message to AT simultaneously on control channel.This call flow hypothesis AT receives 3G1xServices message from target AN.If AT receives 3G1xServices message from source AN, then AT inserts by source AN.In step 1), if the then reception of MS/AT acknowledge message is confirmed in request.At step m) in, when receiving HRPD: during acknowledge message, HRPD AN sends the A14-1x service paging and transmits message to target P CF.

At step n) in, according to the present invention, target P CF transmits message to the Axx paging that source PCF sends the HRPD message that comprises encapsulation.Target P CF opens timer Tprej-xx.At step o) in, if the 1x system request confirms that source PCF replies to the 1x system with this affirmation.

Except the foregoing description, should be understood that the system if not HRPD, the present invention also can be applicable to IEEE 802.11 or 802.16 systems, and we only handle packet data node, and this system is connected with access network authentication, authorization and accounting entity by the A12 interface.Usually, as above use, according to the present invention, the A13 interface is used for transmitting and A13 paging refuse information in other message exchanges A13 paging request, A13 paging.

In a word, the invention provides system and method, be used in the communication system infrastructure that comprises circuit-switched network (cdma2000 1X) and covering packet data network (HRPD), improve the cross-paged between circuit switching and the packet data network, reduce the number that between sub-network, moves the required registration of travelling carriage that causes owing to dormant mobile simultaneously.In addition, the invention provides system and method, be used for the improvement cross-paged being set, reduce the number that between sub-network, moves the required registration of travelling carriage that causes owing to dormant mobile simultaneously in the communication system infrastructure that comprises packet data network (HRPD).

With reference to figure 9, the present invention can be embodied as the different scenes of covering.In first step 60, as preliminary step with for the present invention suitably operates, network should at first be known in the paging of whether supporting between the communication network between packet node.As used herein, network also can refer to sub-network or the zone in the packet data network.For example, communication network can be the sub-network of HRPD (high rate packet data) (HRPD) system, and it allows to carry out cross-paged with cdma2000 1X circuit switching system.In another example, network can be following any one: cdma2000 1X circuit-switched network, HRPD (high rate packet data) (HRPD) network and WiMax network.In one embodiment, the primary importance zone is positioned under the territory of the first grouped data sub-network, and second place zone is positioned under the territory of the second grouped data sub-network, and the both can be covered by the mobile switching centre of 1x cdma2000.
