Embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.

How the embodiment of the invention need to solve packet network is covered lower user, the problem of the MSC/VLR position renewal in the circuit domain core net, thus so that UE can obtain business from MSC by gruping insertion network.Easy to understand, because what the embodiment of the invention solved is: the user under packet network covers upgrades to the MSC/VLR position in the circuit domain core net, therefore, the user under packet network described in the embodiment of the invention covers might not be positioned under the circuit domain covering simultaneously.

The scheme of the embodiment of the invention mainly is by setting up the signalling path between UE and the MSC, and mainly come the completing place to upgrade by the interacting message between UE and MSC, network element can carry out some processing on the way during interacting message, such as the processing to UE address information or positional information.

Fig. 5 is position updating of user's set method implementing procedure schematic diagram, and as shown in the figure, the position can comprise the steps: when upgrading

Step 501, set up in the packet domain signalling path between the MSC in the gruping insertion network and circuit domain;

Concrete, as can to link to each other with gruping insertion network, MSC/VLR by setting grouping access unit is set up UE signalling path between the MSC/VLR in gruping insertion network, divide into groups access unit and circuit domain by the grouping access unit;

Step 502, UE send location update request message by described signalling path to MSC through gruping insertion network;

Step 503, UE is carried out carrying out authentication before the position is upgraded;

Step 504, provide the communication security guarantee to the position updating process of UE;

In order to ensure the safety of UE interacting message, when the passage of setting up between UE and gruping insertion network, can take security mechanism.This security mechanism can be: when UE when gruping insertion network upgrades to the MSC/VLR position, the safety of setting up between UE and gruping insertion network is connected, such as, IP available SEC (IP security protocol, IP security protocol) mode connects.

Step 505, MSC accept location update request message, upgrade to the UE home position by described signalling path and accept message;

Step 506, periodic triggers UE upgrade the position on MSC;

When UE carries out the position renewal by gruping insertion network after, if re-starting the position for a long time, upgrades UE, MSC/VLR can delete the UE data.Need to therefore, after UE is by packet domain access MSC, carry out periodic location update, so the length in how to confirm cycle? in the enforcement, UE can obtain by circuit domain the length in cycle, carries out periodic location update when being used for by the grouping access; Also can be set, so that UE can carry out periodic location update in the expired time of network settings a relatively short cycle in UE.

Step 507, cancel signalling path according to the instruction of HLR.

After MSC/VLR had received Cancel location message from HLR, MSC/VLR can notify related network elements needn't keep the information relevant with UE (such as the IP address information) again, also needn't maintain the signalling path that packet access network is set up again.

When UE supports at least two kinds of access waies, such as, UE can support circuit domain access, LTE (Long-Term Evolution, Long Term Evolution) access, WLAN (Wireless Local Area Network, WLAN (wireless local area network)) multiple (two kinds or more than) access in access, WiMAX (Worldwide Interoperability for Microwave Access, the micro-wave access global inter communication) access etc.UE can be respectively in different access waies UE and set up in the packet domain signalling path between the MSC in the gruping insertion network and circuit domain, and UE sends location update request message by signalling path to MSC/VLR on different access waies; MSC/VLR receiving position update inquiry information is accepted message by signalling path to the renewal of UE home position.

Because user UE may have plurality of access modes, for this class UE, UE can keep a plurality of registration relations simultaneously with MSC/VLR.Method is: UE can utilize the various access waies of supporting to carry out independently position renewal with MSC/VLR and HLR respectively, sets up a plurality of simultaneous registrations relations between UE, MSC/VLR and HLR.

For the situation that distinguishes over the registration relation that user UE only wishes to keep simultaneously unique (or be called user UE want to carry out unit put renewal).When UE carries out the multiposition renewal, can in position updating request, additionally carry identification information.If receive such sign when MSC/VLR and HLR upgrade in the position, MSC/VLR and HLR just can set up the registration relation between new UE, MSC/VLR and HLR when keeping original registration relation (if existence), realize the multiposition update functions.Another kind method, in the time of also can putting renewal in UE sponsor unit, carry sign, MSC/VLR and HLR identify according to this, when accepting this position and upgrade, UE, MSC/VLR and the relation of the registration between HLR that other position updating process is set up are removed, if do not carry described sign, then pressed the multiposition update mode and process.Annotate, above-mentioned multiposition upgrades to process and can only limit to not relate to HLR between MSC/VLR and the UE, and namely MSC/VLR and UE support the relation of many registrations, and only keep a registration relation between MSC/VLR and HLR.

For solving the user under the packet network covering, the problem that MSC/VLR position in circuit domain core net is upgraded, the embodiment of the invention also provides a kind of position updating of user's set system, describes below in conjunction with the embodiment of accompanying drawing to update system.

Fig. 6 is position updating of user's set system configuration schematic diagram, as shown in the figure, comprise the gruping insertion network in the packet domain in the update system, MSC/VLR in the circuit domain, UE through gruping insertion network access network cordless communication network, also comprise the grouping access unit, with gruping insertion network, MSC links to each other, be used for setting up the signalling path between the MSC in UE under the packet domain gruping insertion network and the circuit domain, and the routing function that can give information, also can be compatible UE access MSC take SIP as session control protocol adaption function is provided, and can provide UE to keep simultaneously the function of a plurality of registration relations from multiple access; In the enforcement, UE sends location update request message by signalling path to MSC/VLR through gruping insertion network; MSC/VLR receiving position update inquiry information is accepted message by signalling path to the renewal of UE home position.

Concrete, MSC/VLR: be used for supporting to utilize gruping insertion network to provide professional for the user.

Gruping insertion network: include but not limited to it is traditional SAE or GPRS or CDMA2000 packet field network, can also support to provide to MSC/VLR the positional information of UE.

Borde gateway (grouped data network gateway): the entity in the gruping insertion network is the inner gateway that is connected with extenal grouped network (such as Internet) of gruping insertion network.Such as for the SAE network, be PDN GW, for the GRPS network, then be GGSN, for the CDMA2000 packet field network, then be PDSN.

The grouping access unit: be newly-installed entity, in the enforcement, it can be logic entity, also can be physical entity.Present traditional MSC only supports the access of circuit domain mode, supports undue group access, owing to grouping access and circuit access are two kinds of different access waies.Therefore, if the grouping access is used for MSC, coming provides professional for the user, the embodiment of the invention arranges an entity and realizes this function between gruping insertion network and MSC, among the embodiment this entity is called the grouping access unit, this unit can provide the signalling path between UE and MSC, and routing function can give information, can be compatible UE access MSC take SIP as session control protocol adaption function is provided, and can provide UE to keep simultaneously the function of a plurality of registration relations from multiple access.From the angle of implementing, this entity can be arranged in MSC, also can individualism, can also be arranged in gruping insertion network.In the time of in being melted into MSC, traditional MSC and grouping access unit can be considered as having consisted of together a kind of MSC of enhancing.

As shown in the figure, in the enforcement, MSC links to each other by interface 1 with the grouping access unit, and gruping insertion network links to each other with the grouping access unit by interface 2, wherein:

Interface 1:

Interface between MSC and grouping access unit.This interface can be that (access unit is melted into MSC if will divide into groups for external interface or internal interface, then this access is an internal interface), can the Simulation with I u interface on this interface shape, perhaps simulate the A interface, perhaps simulate Gs, perhaps adopt the interface (such as the interface between core net and Access Network in CDMA2000 network or the TD-SCDMA network) of other form.The annexation of MSC and grouping access unit can be one to one, one-to-many, many-one or multi-to-multi.But the mode of easily knowing one-to-many, many-one or multi-to-multi shall not be applied to the situation that this interface is internal interface.

Interface 2:

Interface between grouping access unit and packet access network.It can be the Gi/SGi interface on this interface shape, it also can be the interface (such as interface newly-increased between grouping access unit and Mobility Management Entity) of other form, can also be internal interface (access unit is melted into packet access network if will divide into groups, and then this interface is an internal interface).The annexation of grouping access unit and packet access network can be one to one, one-to-many, many-one or multi-to-multi.But the mode of easily knowing one-to-many, many-one or multi-to-multi shall not be applied to the situation that this interface is internal interface.

Namely, the grouping access unit can link to each other with gruping insertion network by the interface of Gi/SGi interface or other form in the enforcement, specifically can link to each other with borde gateway or the Mobility Management Entity in the gruping insertion network, by the Simulation with I u interface or the simulation A interface or the simulation Gs interface link to each other with MSC;

Or, the grouping access unit is positioned at gruping insertion network, internal interface by gruping insertion network links to each other with gruping insertion network, specifically can link to each other with borde gateway or the Mobility Management Entity in the gruping insertion network, by the Simulation with I u interface or the simulation A interface or the simulation Gs interface link to each other with MSC;

Or the grouping access unit is positioned at MSC, can be considered the MSC of enhancing, and the grouping access unit links to each other with gruping insertion network by the interface of Gi/SGi interface or other form, links to each other with Anchor MSC by internal interface.

In the enforcement, can comprise at least one grouping access unit in the update system, the grouping access unit provides the signalling path between subscriber equipment and MSC (message Transfer pipe):

1), the enforcement of transmission of messages Path Setup between UE and grouping access unit:

Dual mode is arranged:

Mode one: utilize the IP carrying of gruping insertion network (to comprise and to utilize UE when packet access network adheres to that packet access network is the default IP carrying that UE sets up; The IP carrying of perhaps in packet access network, setting up separately, the carrying that utilizes PDP (Packet Data Protocol, packet data protocol) context activation process to set up such as dedicated bearer and the GPRS of SAE).And external interface (such as Gi or the SGi) interface that utilizes grouped data network gateway to provide, consisting of the transmission of messages passage between UE and grouping access unit, the essential characteristic of this transmission of messages passage is that passage is through a minute winding data network gateway.Can set up signalling path by the host-host protocol such as TCP or UDP or SCTP and UE between the grouping access unit.

Mode two: utilize in UE and the gruping insertion network original transmission of messages passage between Mobility Management Entity, and the interface between newly-increased Mobility Management Entity and grouping access unit, consist of from UE and the transmission of messages passage that divides into groups between access unit.The essential characteristic of this transmission of messages passage is that passage is through Mobility Management Entity.

2), the enforcement of transmission of messages Path Setup between grouping access unit and MSC:

The employed passage of transmission of messages between grouping access unit and MSC, can adopt Iu-CS or the wireless access network control interface of the networks such as A interface or CDMA2000 or the mode that other form interface provides, if MSC closes with the grouping access unit and establishes, then described passage is arranged in internal interface, in this case, the execution mode of passage is not limited to above form.

The grouping access unit can pass through the first address designation; The MSC that is used for upgrading the position then can pass through the second address designation.Then:

(1), update system can further include the first determining unit and/or the second determining unit, the first determining unit is used for being identified for UE and carries out the grouping access unit that the position is upgraded, the second determining unit is used for being identified for UE and carries out the MSC that the position is upgraded.

The first determining unit links to each other with UE, or links to each other with Mobility Management Entity.If link to each other with UE, can be used for determining described the first address for UE from grouped data network gateway or Mobility Management Entity; Also can be used for determining described first address by DHCPv6 (Dynamic Host Configuration Protocol V6, DHCP v6) mode from Dynamic Host Configuration Protocol server for UE; Also can be used for determining described the first address from UE or in the configuration of subscriber card for UE.If link to each other with Mobility Management Entity, can be used for from configuration, determining the first address for Mobility Management Entity, in this case, UE can determine Mobility Management Entity by prior art, determine the first address by Mobility Management Entity by the first determining unit, and needn't determine the first address by the first determining unit by UE.

The second determining unit links to each other with UE, or links to each other with the grouping access unit.If link to each other with UE, can be used for determining described the second address for UE from grouped data network gateway or Mobility Management Entity; Also can be used for determining described second address by the DHCPv6 mode from Dynamic Host Configuration Protocol server for UE; Also can be used for determining described the second address from UE or in the configuration of subscriber card for UE.If link to each other with the grouping access unit, can be used for from the configuration of grouping access unit, determining the second address, in this case, location update message arrives the grouping access unit by the first address of determining first, and then determines the second address by the grouping access unit.

The first and second determining units can further include parsing module, are used for carrying out domain name mapping by described the first address, second address of the name server domain name mode that determining unit is definite, and domain name is mapped to the IP address.

Concrete, the first and second determining unit purposes are to upgrade definite targeted packets access unit and target MSC for UE carries out the position, the route that is used for the message between UE and MSC: because when UE carries out the position renewal by gruping insertion network to circuit domain core net, need to determine a grouping access unit and target MSC, come to upgrade for the user carries out the position, and provide professional follow-up.

In the enforcement, determine grouping access unit and MSC for UE, four kinds of approach can be arranged:

Approach A, UE obtain first to divide into groups (i.e. first address, address of access unit, can be IP address or domain name) in form, the first address is so that UE can be addressed to the grouping access unit, and then be defined as this UE by the grouping access unit professional MSC (namely the second address can be MSC number in form) is provided.

Approach B, UE directly obtain the first address and the second address, and at this moment, UE is according to the grouping of the first addressing of address in location update message access unit, and the grouping access unit is according to the second addressing of address MSC in the location update message.

If be one to one or the relation of unification between approach C grouping access unit and MSC, the UE address information of access unit or MSC that only need to obtain to divide into groups then obtains this address information and is equal to and obtains another address information.

Approach D, UE needn't be known the first and second addresses, UE utilizes Mobility Management Entity to carry out the position renewal by the existing signalling path between UE and Mobility Management Entity, determine the first address by Mobility Management Entity, for the second address, can be determined by Mobility Management Entity, also can be to update message in the position when reaching grouped element to be determined by the grouping access unit.

During implementation, for above A, B and three kinds of approach of C, how UE obtains in approach A how the first address, UE obtain the first and second addresses in approach B and how UE obtains the first or second address in approach C, can be undertaken by following three kinds of modes:

Mode A, UE obtain first, second address information from grouped data network gateway or Mobility Management Entity.

UE or setting up IP when carrying, provides described address information by grouped data network gateway or Mobility Management Entity to UE when being attached to Packet Data Network, this information comprises at least one described address.If comprise a plurality of described addresses, then can make a choice to carry out the position by UE and upgrade.Can before upgrading, the UE position in grouped data network gateway or Mobility Management Entity, dispose first, second address information.

Whether grouped data network gateway or Mobility Management Entity provide described address information to UE, can be unconditional, also answer the request of UE and determine whether send this information.If what obtain is the address information of domain name mode, then further carry out domain name mapping by name server by parsing module, domain name is mapped to the IP address.

Mode B, UE obtain first, second address information by the DHCPv6 mode.

To the described address information of Dynamic Host Configuration Protocol server request domain name mode or the described address information of IP address mode, this address information comprises at least one address information to UE by the DHCPv6 mode.If comprise a plurality of address informations, then can make a choice to carry out the position by UE and upgrade.If what obtain is the address information of domain name mode, then further carry out domain name mapping by name server by parsing module, domain name is mapped to the IP address.

Mode C, also can be directly first, second address information of configuration in UE or in the subscriber card.

During implementation, for above A and D approach, grouping access unit how to confirm MSC if the grouping access unit only links to each other with a MSC, or unifies with MSC, and then target MSC is well-determined; If a grouping access unit links to each other with one or more MSC, the access unit that then divides into groups determines that target MSC (namely determining the second address) can be undertaken by following dual mode:

Mode A, can by the configuration method solve.Described configuration can be presented as the corresponding relation in configuration UE present position zone and MSC in the grouping access unit; The perhaps corresponding relation of UE (or corresponding user identity) and MSC.According to this configuration information and the residing band of position of user UE or UE (or corresponding user identity) identification information, the grouping access unit can be determined target MSC.

Mode B: needn't the described configuration relation of set-up mode A in the grouping access unit, but the grouping access unit makes a choice to determine a MSC.Can be based on certain strategy, such as load sharing (Mobility Management Entity can be shared business on a plurality of MSC); Or select arbitrarily one, and in this case, for a user, when the grouping access unit will guarantee follow-up and MSC mutual, selects constant MSC, the grouping access unit can adopt and record the selection result mode and realize this point.

During implementation, for above D approach, Mobility Management Entity how to confirm grouping access unit can be identical with the method for grouping access unit how to confirm MSC among the aforesaid way D.

(2), update system can further include the 3rd determining unit, links to each other with MSC, be used to MSC to be identified for UE and carry out the grouping access unit that the position is upgraded; And the 4th determining unit, link to each other the UE that is used to the grouping access unit to determine to carry out the position renewal with the grouping access unit.

The 3rd determining unit links to each other with MSC/VLR, is used to MSC/VLR to mail to the route of message of the grouping access unit of UE, determines the address of grouping access unit.The 3rd determining unit can be determined the grouping access unit that UE is corresponding with the mapping relations of grouping access unit according to positional information and the described positional information of UE, perhaps, MSC/VLR receives first the message from the grouping access unit for UE, grouping access unit corresponding to MSC/VLR record UE, thus determine grouping access unit corresponding to UE.

The 4th determining unit links to each other with the grouping access unit, is used to the grouping access unit to determine the UE address information.The 4th determining unit can determine to carry out the UE address information that the position is upgraded according to the location update request message of UE.If location update request message comes from Mobility Management Entity, then the divide into groups address information of mobile management body corresponding to access unit record UE, engage (in the prior art) Mobility Management Entity to the addressability of UE, the grouping access unit can be addressed to UE, perhaps, Mobility Management Entity offers the grouping access unit with the IP address of UE, and the grouping access unit is by the IP address information addressing UE of UE; If location update request message comes from grouped data network gateway, the IP address of the access unit record UE that then divides into groups, the grouping access unit is by the IP address information addressing UE of UE.

Concrete, in location update message reciprocal process, MSC need to be identified for UE and carry out the grouping access unit that upgrades the position, the UE that the grouping access unit need to determine to carry out the position renewal, carries out the interacting message that the position is upgraded between guarantee UE, MSC/VLR and HLR.In this process, each entity can be processed in the following manner:

1, MSC/VLR obtains the UE positional information.

The positional information of UE can offer MSC/VLR by the entity in UE or the network, specifically can be as follows:

1) if select to provide the positional information of UE by UE to MSC/VLR, UE can carry this information in position updating request;

2) if select to be provided to MSC/VLR by the entity in the network positional information of UE, this network entity can be the Mobility Management Entity (such as being SGSN for the GRPS network, then being MME for the SAE network) in grouping access unit or the gruping insertion network.

If select the grouping access unit that user's positional information is provided, being not limited to the opportunity of positional information transmission is that the access unit that divides into groups together passes to MSC/VLR with this positional information when the grouping access unit is received position updating request from UE;

If select Mobility Management Entity that user's more specific location information is provided, Mobility Management Entity can be with the location information notification of UE to the packet domain gateway device, and then by gateway device message is offered the grouping access unit, offer MSC/VLR by the grouping access unit at last, also can be Mobility Management Entity offers the grouping access unit with the positional information of UE, and then offer MSC/VLR, can also be Mobility Management Entity directly offers MSC/VLR with the positional information of UE.

2, MSC mails to the route of the message of UE.

For so that MSC can by grouping access unit addressing UE, need to solve the problem of following two aspects:

1), MSC need to obtain the address information of the corresponding grouping access unit of UE.

Solve this moment and can carry out in the following manner:

A, when MSC need to send message to the grouping access unit, MSC can be according to the information of the address of the access unit that respectively divides into groups of the mapping relations of each positional information of the positional information of user UE, MSC record and each grouping access unit and MSC record, divide into groups the accordingly address information of access unit of acquisition UE.

B, when MSC receives that relevant message is upgraded in the UE position, the grouping access unit address information in the recording messages, and record the corresponding relation of itself and UE.

2), the grouping access unit needs to be addressed to UE.

The grouping access unit is in the process that UE carries out upgrading the position, and the grouping access unit can carry out the position with UE by grouped data network gateway or Mobility Management Entity to be upgraded alternately.

If by grouped data network gateway, the access unit that then divides into groups need to obtain the IP address information of UE.The mode of taking can be: when the grouping access unit is received message from UE, and the IP address that from message, obtains and record UE.

If by Mobility Management Entity, then grouped data network gateway need to obtain Mobility Management Entity corresponding to UE.The mode of taking can be: when the grouping access unit receive through Mobility Management Entity from the message of UE the time, the Mobility Management Entity address that from message, obtains and record the current correspondence of UE.

3, in the position updating process, the position of MSC/VLR and HLR is upgraded the processing of processing in the time of can carrying out the position renewal from circuit domain with the user and is consistent.

4, the location update message between UE and MSC/VLR is mutual.

Four kinds of interacting message modes can be arranged here:

Mode one: UE carries out the position when upgrading at the grouped data network gateway in gruping insertion network or Mobility Management Entity to MSC/VLR, the location update request message of sending in form can with UE by traditional circuit domain to MSC carry out the position when upgrading entrained information identical.This message can adopt sip message packing forms (such as using SIP Info message), but the content in the message body is the circuit domain location update message, the grouping access unit can convert the message encapsulation of UE side to the encapsulation of Iu or A interface shape, offers MSC/VLR after the conversion.

Mode two: UE carries out the position when upgrading at the grouped data network gateway in gruping insertion network or Mobility Management Entity to MSC/VLR, can adopt the SIP logon mode, Fig. 7 upgrades the implementing procedure schematic diagram for adopting the SIP logon mode to carry out the position through the grouping access unit to MSC/VLR, as shown in the figure, this process can be implemented as follows:

Step 701, UE send SIP Register message by gruping insertion network to the grouping access unit.

Step 702, grouping access unit send SIP Register message to MSC.

Step 707, MSC send SIP 200 OK message to the grouping access unit.

Step 708, grouping access unit send SIP 200 OK message through gruping insertion network to UE.

Further can also comprise authenticating unit, be used for described UE being carried out carry out authentication before the position is upgraded.If MSC will carry out authentication to user UE, then the step 702 in said process and step 707 authenticating unit can be implemented in the following manner:

Step 703, MSC send SIP 401 Unauthorized message to the grouping access unit.

Step 704, grouping access unit grouping access unit are sent out UE to sending SIP 401Unauthorized message through gruping insertion network.

Step 705, UE send SIP Register message by gruping insertion network to the grouping access unit.

Step 706, grouping access unit send SIP Register message to MSC.

Wherein, the private user identity in the SIP Register message in the step 701 can be IMSI or TMSI, or the derivative form of this two classes number, and public user identity can be Mobile Subscriber International ISDN Number or its derivative form.When MSC receives this message of SIP Register message, can extract IMSI/TMSI and MSISDN code.

Mode three: UE also can register by the SIP logon mode, the grouping access unit will be changed between SIP registration process and circuit domain position updating process, the implementing procedure schematic diagram that Fig. 8 will change between SIP registration process and circuit domain position updating process for the grouping access unit, as shown in the figure, transfer process can comprise the steps:

Step 801, UE send SIP Register message by gruping insertion network to the grouping access unit.

Step 802, grouping access unit send Location Update Request message to MSC.

Step 807, MSC send Location Update Accept message to the grouping access unit.

Step 808, grouping access unit send SIP 200 OK message through gruping insertion network to UE.

If MSC will carry out authentication to user UE, then also has following reciprocal process in the step 802 of said process and step 807.

Step 803, MSC send Authentication Request message to the grouping access unit.

Step 804, grouping access unit grouping access unit are sent out UE to sending SIP 401Unauthorized message through gruping insertion network.

Step 805, UE send SIP Register message by gruping insertion network to the grouping access unit.

Step 806, grouping access unit send Authentication Response message to MSC.

Wherein:

In above-mentioned steps 801, the header field filling method in the described SIP Register message can be:

" request URI " header field extends this as above-mentioned " the first address ", " the second address ", or the address of its derivative form.If UE need to carry above-mentioned two address informations simultaneously in the message that sends the grouping access unit, then can be in SIP Register message affix except another address information in " request URI ".

The publicly-owned identify label of user in " From " and " To " header field can extend this as MSISDN (Mobile station international ISDN number, 2G/3G phone number), or its capable form sign of deriving.

Private user identity sign in " Authorization " header field extends this as user's IMSI (International Mobile Subscriber Identifier, international mobile subscriber identifier) or TMSI (Temporary Mobile Station Identity, or its derivative form sign temporary mobile subscriber identity).

The address information that " Contact " header field is filled in UE can be IP form or URI (Universal Resource Identifier, unified resource sign) form.

In above-mentioned steps 802, the information filling method in the described Location Update request message can be:

" Mobile identity " extends this as the IMSI described in the step 801 or TMSI.

" Location area identification " fills in the UE positional information that obtains.

Mode four: upgrade if utilize Mobility Management Entity to carry out the position to MSC/VLR, Mobility Management Entity can or adhere to when the request of gruping insertion network of being attached to of receiving UE finish after, carry out the position by Mobility Management Entity to MSC/VLR and upgrade.So, be to carry out interacting message by the mode that UE is attached to gruping insertion network between UE and Mobility Management Entity, mutual between Mobility Management Entity and MSC/VLR is that message can be any one in above-mentioned three kinds of modes.Fig. 9 is that UE is when adhering to gruping insertion network, carry out the implementing procedure schematic diagram that the position is upgraded by Mobility Management Entity to MSC/VLR, among this figure, Mobility Management Entity has adopted the setting of unifying with the grouping access unit, as shown in the figure, this process can be implemented as follows:

Step 901, UE send to gruping insertion network Mobility Management Entity (grouping access unit) and adhere to request.

Step 902, Mobility Management Entity (grouping access unit) send location update request message to MSC/VLR.

Step 903, MSC/VLR send the position renewal to Mobility Management Entity (grouping access unit) and accept message.

Step 904, Mobility Management Entity (grouping access unit) send to adhere to UE accepts message.

For mode four, whether Mobility Management Entity carries out the position of UE is upgraded to MSC/VLR, can depend on the indication of UE.This indication can be that UE carries to Mobility Management Entity when gruping insertion network adheres to.As another kind of option, Mobility Management Entity also can be by configuration, does not rely on the indication of UE and judges whether to carry out the position and upgrade.

For mode four, Mobility Management Entity can carry user's positional information in the position updating request of MSC transmission.If the positional information of using among the positional information of the UE in the Mobility Management Entity and the MSC is different in form, then need the positional information in the gruping insertion network is converted to positional information among the MSC, this processing can be carried out in Mobility Management Entity, in this case, the positional information that passes to MSC is after the conversion; This processing also can be carried out in MSC, and in this case, the positional information that passes to MSC is before the conversion; An intermediate entities also can be set between Mobility Management Entity and MSC finish this processing.

For mode four, Mobility Management Entity can upgrade the result with the position and notify to UE.Concrete grammar can be that the response message that adheres to that Mobility Management Entity utilizes UE to be attached to gruping insertion network notifies the result to UE.Distribute TMSI if MSC is UE, also can in this message, offer UE.

Can further include the cancellation unit in the update system, be used for MSC and cancel signalling path according to the instruction triggers grouping access unit of HLR.When MSC/VLR received annotate (Cancel location) message that disappears from the position of HLR after, but MSC/VLR notice packet access unit, the grouping access unit needn't keep the information relevant with UE (such as the address information of routing decision information and UE etc.) again, also needn't maintain (signaling) passage of packet access network foundation again.

Update system can further include the periodic location update unit, links to each other with UE, is used for the position of periodic triggers UE on MSC and upgrades.When UE carries out the position renewal by gruping insertion network after, if re-starting the position for a long time, upgrades UE, MSC/VLR can delete the UE data.After UE is by packet domain access MSC, need to carry out periodic location update, UE can obtain Cycle Length by circuit domain, carries out periodic location update when being used for this Cycle Length by the grouping access; Also can be set as Cycle Length, so that UE can carry out periodic location update in the expired time of network settings a relatively short cycle in UE.

When update system has at least two kinds of access waies at UE, such as, UE can support the multiple access in circuit domain access, LTE grouping access, WLAN grouping access, the WiMAX grouping access etc.The grouping access unit is respectively UE according to the access way of UE and sets up in the packet domain signalling path between the MSC in the gruping insertion network and circuit domain; UE upgrades related news through gruping insertion network by sending the position with the corresponding signalling path of access way to MSC according to access way; MSC accepts location update request message, by upgrading related news with the corresponding signalling path of access way to the UE home position.

Because user UE may have multiple access capability, therefore, for this class UE, UE can keep a plurality of registration relations simultaneously with MSC.The employing method can be: UE can utilize the various access waies supported respectively and MSC/VLR and HLR carry out independently the position a plurality of simultaneous registrations relations between UE, MSC/VLR and HLR of setting up of more newly arriving.

For the situation that distinguishes over the registration relation that user UE only wishes to keep simultaneously unique (or be called user UE want to carry out unit put renewal).A kind of method is: when UE carries out the multiposition renewal, can additionally carry identification information in position updating request.If receive such sign when MSC/VLR and HLR upgrade in the position, MSC/VLR and HLR just can when keep original registration relation, set up the registration relation between new UE, MSC/VLR and HLR, thereby realize the multiposition update functions.

Another kind method is: also can put in UE sponsor unit and carry sign when upgrading, MSC/VLR and HLR identify according to this, when accepting this position and upgrade, UE, MSC/VLR and the relation of the registration between HLR that other position updating process is set up are removed, if do not carry described sign, then press the multiposition update mode and process.

The processing that another multiposition upgrades relates generally to the grouping access unit, with respect to top mode, for the processing that keeps MSC/VLR and HLR constant, when UE has multiple (two kinds or more than) grouping access capability, UE can upgrade to MSC/VLR difference launch position through same grouping access unit by various grouping access waies, MSC/VLR and HLR only need to keep by the processing mode of prior art the registration relation of a UE, but the grouping access unit can be set up a plurality of registration relations (being presented as that the grouping access unit can record UE corresponding to the address information of different access waies) of UE.

Figure 10 for the grouping access unit at the address information handling process schematic diagram to the UE that possesses plurality of access modes, as shown in the figure, step 1001-1004 upgrades handling process for the grouping access unit carries out a position at UE by gruping insertion network 1, finished the registration of UE to MSC/VLR and HLR, in this process, the grouping access unit is recorded UE in the address information of gruping insertion network 1 correspondence;

In the step 1005, UE carries out once new position renewal by gruping insertion network 2, and the grouping access unit directly sends the position renewal to UE and accepts message after receiving position updating request, and the address information of record UE correspondence in gruping insertion network 2.

By the above-mentioned processing of grouping access unit, UE just can carry out Business Processing by gruping insertion network 1 or gruping insertion network 2.

In order to ensure the transmission security problem between UE and grouping access unit, update system can further include safe unit, links to each other with grouping access unit, UE, is used for providing the communication security guarantee to the position updating process of UE.

In order to ensure the safety of interacting message between UE and grouping access unit, when the passage of setting up between UE and grouping access unit, can take security mechanism.This security mechanism is: when UE when upgrading to the MSC/VLR position, sets up UE and safe connection of dividing into groups between access unit through the grouping access unit, such as, IP available SEC mode connects.

Figure 11 is for ensureing the implementing procedure schematic diagram of the safety of interacting message between UE and grouping access unit, and as shown in the figure, safe unit can implement to provide the communication security guarantee according to the following steps:

When step 1101, UE are upgraded to grouping access unit launch position, parameter safe to carry, for IPSEC then correspondence be the UE port information, comprise two ports of client and service end.

Step 1102, grouping access unit send position updating request to MSC/VLR;

Step 1103, after MSC/VLR receives position updating request, to grouping access unit return messages, parameter safe to carry comprises safe key.

Step 1104, next the access unit that divides into groups provides security parameter to UE, comprises client and two port informations of service end of the access unit that divides into groups.

By security parameter mutual between above-mentioned UE and grouping access unit, and the safe key in UE and the grouping access unit, just can set up safe transmission channel between UE and grouping access unit.

The embodiment of the invention also provides a kind of position updating of user's set device, be used for comprising the gruping insertion network, the MSC/VLR in the circuit domain (mobile switching center/visitor location register) of packet domain, through the communication system of the user equipment (UE) of gruping insertion network access to wireless communication network, this device links to each other with gruping insertion network, MSC/VLR, is used for providing the signalling path of UE between gruping insertion network, grouping access unit and circuit domain MSC/VLR;

Subscriber equipment sends position by described signalling path to described MSC/VLR through gruping insertion network and upgrades related news;

MSC/VLR accepts location update request message, upgrades related news by described signalling path to the subscriber equipment home position.

Concrete, this device can be by the interface between Gi/SGi interface and Mobility Management Entity, link to each other with Mobility Management Entity or grouped data network gateway in the gruping insertion network, by the Simulation with I u interface or the simulation A interface or the simulation Gs interface link to each other with MSC/VLR;

Or, be arranged in Mobility Management Entity or the grouped data network gateway of gruping insertion network, link to each other with Mobility Management Entity or grouped data network gateway in the gruping insertion network by internal interface, link to each other with MSC/VLR by Simulation with I u interface or simulation A interface or simulation Gs interface;

Or, be positioned at MSC/VLR, by the interface between Gi/SGi interface and Mobility Management Entity, link to each other with Mobility Management Entity or grouped data network gateway in the gruping insertion network, the internal interface by MSC/VLR links to each other with MSC/VLR.

The position updating device can further include the first message conversion processing module and/or the second message conversion processing module of processing for message conversion, wherein:

The first message conversion processing module, be used for after receiving the notice that Mobility Management Entity sends, send location update request message to MSC/VLR, described notice is after Mobility Management Entity receives that UE is attached to the request message of gruping insertion network, the notice of sending to the grouping access unit.

Further, can also comprise mapping block, be used for obtaining the positional information of UE under packet domain from Mobility Management Entity, UE is mapped to the circuit domain positional information in the positional information under the packet domain be carried in the location update request message.
