Embodiment

In order to solve the problem that the ICS framework exists, the embodiment of the invention is transformed MSC Server functional module traditional among Fig. 2, as shown in Figure 4, and for the embodiment of the invention proposes a kind of enhancement mode MSCServer (EMSC).MSC Server traditional among the EMSC that the embodiment of the invention proposes and Fig. 2 compares, keep MSC Server and carried out the ability that soft switch service is handled, also increase ISC interface adaption function, service-impacting coordination function (Service Broker) and Diameter function simultaneously, and strengthened CCF (Enhance Call Control).

The ISC interface adaption function:

If the business of terminal unit contractual only limits to soft switch service, then can provide service for terminal by the R4 network; If the business of terminal unit contractual not only has soft switch service to also have the IMS business, then the AS that the IMS business of terminal request is toggled in the IMS network is handled by newly-increased ISC interface adaptation module.

Service Broker function:

When if the business of terminal unit contractual clashes, Service Broker can coordinate the business that clashes by pre-configured coordination principle.Here the business of terminal unit contractual includes but not limited to the soft switch service of EMSC inside and the IMS business among the IMS AS.

The Diameter function:

Be optional function, be used to discern, translate the signaling of Diameter.Consider the concurrently deployed initial stage of IMS network and flexible exchanging network, HSS and attaching position register (HLR) may not possess the data sync ability, and the information of terminal unit contractual IMS Network may only be kept among the HSS, do not have relevant information in HLR.Therefore in order to obtain this information, need EMSC to pass through the Diameter interface and initiate query requests, obtain the signing service sign of terminal in the IMS network, thereby finish the professional flow process that triggers to HSS.

Enhance?Call?Control：

EMSC strengthens the Call Control function among traditional MSC Server, it is upgraded to Enhance Call Control, at terminal unit contractual IMS when professional, Enhance Call Control not only can handle the business in the flexible exchanging network, can also carry out business to the AS in the IMS network and trigger, the signaling in the identification IMS network.

EMSC in the embodiment of the invention be equivalent to the comprehensive of P-CSCF and S-CSCF in the IMS network, and for flexible exchanging network, EMSC still plays a part traditional MSC Server for the IMS network.IMS network and flexible exchanging network can be realized intercommunication on the function by EMSC.

Because the EMSC that the embodiment of the invention proposes can realize the intercommunication of IMS network and flexible exchanging network, compares with the ICS framework, and is less to the transformation amount of network, do not need additionally to build TAS to realize support to telecommunication service; Simultaneously, therefore business in all right executive software switching network of EMSC in the embodiment of the invention has guaranteed professional consistency, and, avoid under the ICS structure service needed in the flexible exchanging network by IMS network route, solved the signaling process complicated problems.

Embodiment one:

The embodiment of the invention one is to utilize EMSC that the present invention proposes to realize that terminal in the flexible exchanging network moves the signing service in the IMS network and the scheme of the signing service in the flexible exchanging network simultaneously, for convenience of description, terminal in the flexible exchanging network is referred to as terminal, EMSC in the embodiment of the invention also can be regarded as the improvement to MSC, therefore, also be referred to as MSC.

In present embodiment one, suppose that current terminal is positioned at a MSC control area, then present embodiment one provide signing service professional ability method as shown in Figure 5, may further comprise the steps:

Step 101: the setup requests that a MSC receiving terminal sends.

When starting up of terminal or when moving to a MSC control area, send setup requests to a MSC.

Step 102: a MSC obtains the signing service information of described terminal, according to signing service in the described signing service information IMS network of having determined described terminal unit contractual and the signing service in the flexible exchanging network.

The signing service information of terminal can comprise signing service information in the IMS network and/or the signing service information in the flexible exchanging network.In the present embodiment, the signing service information of terminal comprises: signing service information in the IMS network and the signing service information in the flexible exchanging network.

Step 103: extract the signing service sign in application server (AS) address and the IMS network in the signing service information of a MSC from the IMS network.

Wherein, the sign of the signing service sign expression terminal actual signing service in the IMS network in the IMS network, the indication of AS address provides the AS of the professional ability of terminal unit contractual business.

Step 104: the service request that a MSC will comprise the signing service sign in the IMS network sends to the AS of described AS address correspondence.

In the present embodiment, the signing service sign in the IMS network can comprise the sign of many business, the IMS business that the sign counterpart terminal of every business is signatory.After the service request that the one MSC will comprise the signing service sign in the IMS network sends to AS, just and set up the grappling relation between the AS, AS is considered as S-CSCF in the IMS network with a MSC, for terminal provides the signing service sign in the IMS network corresponding professional professional ability.

Step 105: extract the signing service sign in SCP address and the flexible exchanging network in the signing service information of a MSC from described flexible exchanging network.

Signing service information in the flexible exchanging network comprises: the CAMEL Subscription Information of making a start (the Originating CAMEL Subscripting Information that terminal triggers as calling terminal, O-CSI), the receiving end CAMEL Subscription Information that triggers as called end of terminal (Terminating CAMEL SubscriptionInformation, one or more T-CSI) and in the number segment trigger message.If comprise O-CSI in the signing service information in the flexible exchanging network, then O-CSI comprises the signing service sign of at least one business; If comprise O-CSI in the signing service information in the flexible exchanging network, then T-CSI comprises the signing service sign of at least one business.The signing service of each business sign can corresponding SCP address, and the professional ability of representing this signing service sign is provided by the SCP of the SCP address indication of correspondence.

Step 106: the service request that a MSC will comprise the signing service sign in the flexible exchanging network sends to the SCP of SCP address correspondence.

In this step, after SCP receives service request, will provide the signing service sign corresponding professional professional ability for terminal, for example, if that carry in the service request is O-CSI, then SCP provides the corresponding business ability according to the terminal that is designated of the terminal of wherein carrying; If that carry in the service request is T-CSI, then SCP provides the corresponding business ability according to the terminal called that is designated of the terminal called that wherein carries.

SCP is not and set up grappling relation between the MSC, but set up the professional incidence relation that triggers, after a MSC sends to SCP with service request, will and SCP between no longer include annexation, SCP will not be considered as the connection of terminal unit contractual business with being connected of a MSC yet, and any MSC can send service request to SCP for a certain terminal.

In the scheme of the embodiment of the invention one, the execution sequence of step 103 and step 105 is unfixing, can be that two steps are carried out simultaneously.

Scheme by above step 101～step 106, because a MSC has on the basis of soft switch service disposal ability and also has the IMS traffic handing capacity simultaneously, therefore, carry out simultaneously under the situation of soft switch service and IMS business in the permission terminal, transformation amount to network is less, and a MSC has the soft switch service ability, does not need additionally to build TAS to realize the support to telecommunication service; Simultaneously, in the scheme of present embodiment one, can carry out according to traditional soft switch flow process from the calling that flexible exchanging network is initiated, less to existing signaling transformation, traffic delay is also less.

At a MSC before AS and SCP send service request, need further to determine in the signing service and the signing service in the flexible exchanging network of terminal in the IMS network, whether there are any two or more business to clash,, then need to solve service conflict if there is conflict.In the present embodiment, the method for solution service conflict includes but not limited to following two kinds of methods:

First method: the execution of at least one business of cancellation from the business that clashes, by cancelling professional execution, avoid the conflict between the multi-service.

Can when determining to clash between multi-service, can cancel the execution of the minimum one or more business of its medium priority for signing service in the IMS network and the setting of the signing service in flexible exchanging network priority in this method.Because some business of terminal unit contractual is cancelled, therefore, in the service request of AS or SCP transmission, need to remove the professional signing service sign of cancellation.Specific practice is: if the professional corresponding signing service sign of cancellation is the signing service sign in the IMS network, then other signing service signs except that the professional corresponding signing service sign of cancellation in the sign of the signing service in the IMS network that extracts is carried at and sends to described AS in the service request; If the professional corresponding signing service sign of cancellation is the signing service sign in the flexible exchanging network, then other signing service signs except that the professional corresponding signing service sign of cancellation in the sign of the signing service in the flexible exchanging network that extracts is carried at and sends to described SCP in the service request.

Second method: adjust the professional execution sequence of conflict, professional by carrying out successively, avoid the conflict between the multi-service.

Can when determining to clash between multi-service, can carry out the business that clashes successively for signing service in the IMS network and the setting of the signing service in flexible exchanging network priority in this method according to priority order from high to low.Because the business of terminal unit contractual will be carried out in a certain order, therefore, after determining execution sequence for the business that clashes, need notice AS and SCP, concrete way is: a MSC will comprise the signing service sign in the IMS network and adjust after the service request of execution sequence of the conflict business that obtains send to described AS; EMSC will comprise the signing service sign in the flexible exchanging network and adjust after the service request of execution sequence of the conflict business that obtains send to described SCP.

The embodiment of the invention provides a kind ofly can solve the problem that the ICS framework exists for the soft switch terminal provides the method for IMS business, further, the embodiment of the invention is also considered the terminal different mobile management feature in IMS network and flexible exchanging network in the flexible exchanging network, proposition under the network environment of embodiment one, position updating process and the handoff procedure of terminal in moving process.

The mobile management feature of terminal in the IMS network is: the IMS network is in case be selected certain serving CSCF (S-CSCF) of terminal, in the whole signing service implementation of terminal, this S-CSCF can not change, and promptly AS will think always that terminal is the terminal of this S-CSCF service.And terminal in the mobile management feature of flexible exchanging network is: will constantly change along with the position change of terminal for terminal provides the MSC of service in the flexible exchanging network.

Because terminal is different with mobile management feature in the IMS network at flexible exchanging network, therefore, the mobile management that position updating process that the embodiment of the invention two～embodiment ten proposes and handoff procedure can compatible two kinds of networks.

Embodiment two:

MSC among follow-up each embodiment of the present invention and the 2nd MSC are the EMSC that proposes in the present invention, wherein, the one MSC is the source MSC before terminal moves, the 2nd MSC is the purpose MSC after terminal moves, first base station controller (BSC) is the network element that is subjected to MSC control and is connected with a MSC with first Visited Location Registor (VLR), and the 2nd BSC is the network element that is subjected to the 2nd MSC control and is connected with the 2nd MSC with the 2nd VLR.Wherein, VLR and MSC can integrate, and also can be provided with respectively.

Consider when terminal when moving to the 2nd MSC control regional under the network environment of embodiment one from the zone of MSC control, because under the mobile management feature in the IMS network, grappling relation between an AS and the MSC still exists, AS thinks that still the registration that terminal is initiated is effective when a MSC, therefore, after terminal moves to the 2nd MSC, the 2nd MSC can't finish and AS between grappling, cause terminal can't enjoy the professional ability that AS provides.

The embodiment of the invention two is a kind of updating of terminal position schemes that propose on the basis of embodiment one, make terminal move to the 2nd MSC control area from a MSC control area after, terminal still can be enjoyed the ability of the IMS network contraction business that AS provides.

As shown in Figure 6, the method flow schematic diagram for the embodiment of the invention two may further comprise the steps:

Step 201: a MSC is according to the scheme of embodiment one, by business in the IMS network of AS and SCP execution terminal unit contractual and the business in the flexible exchanging network.

This step proposes the applied environment of present embodiment, that is: the terminal unit contractual in the flexible exchanging network signing service in the IMS network and the signing service in the flexible exchanging network, and the grappling relation that has the professional ability of the signing service be used for indicating AS that the IMS network is provided between MSC and the AS, and MSC has the performance that indication SCP provides the professional ability of the signing service in the described flexible exchanging network.

Step 202: when terminal when a MSC control area moves to the 2nd MSC control area, HLR receives the location update message of self terminal.

Step 203:HLR sends position deletion message to a VLR.

The HLR that relates in the various embodiments of the present invention is the HLR of terminal attaching, and after terminal was registered in a certain MSC, MSC sent to HLR with the log-on message of terminal.Receive the location update message of self terminal as HLR after, then send position deletion message, require the user profile of the terminal of VLR deletion storage to a VLR.。

Step 204: a VLR indicates the grappling relation between MSC release and the described AS after receiving described position deletion message.

The one VLR indicates the concrete grammar of the grappling relation between MSC release and the AS to be:

At first, a VLR sends grappling to a MSC and concern release message, requires a MSC to be released to described terminal and concerns with grappling that AS sets up.

Then, a MSC sends the de-registration request of the terminal iidentification that comprises described terminal to AS.

At last, AS carries out the user log off operation according to the terminal iidentification in the de-registration request to terminal, and at this moment, the grappling relation between a MSC and the AS discharges, and AS returns the cancellation response message to a MSC, the incident that notice grappling relation discharges.

Step 205: a VLR is to HLR home position deletion response message.

In step 203, it is the user profile of requirement the one VLR deletion terminal that HLR sends position deletion message to a VLR, and after a VLR receives position deletion message, at first indicate a MSC to carry out the dispose procedure of grappling relation, after the relation of the grappling between a MSC and the AS discharges, the one MSC will return grappling relation to a VLR and discharge response, concern that to notify a VLR grappling release event finishes.After the one VLR receives described grappling relation release response, delete the user profile of the described terminal of self storing, to HLR home position deletion response message, the deletion event of information of terminal user has been finished in expression then.

Step 206:HLR sends the user profile of terminal to the 2nd VLR after receiving described position deletion response message.

Because a VLR has deleted the user profile of terminal, therefore, HLR requires terminal to move the back and preserves the user profile of terminal for terminal provides the 2nd VLR of service.

The user profile of terminal comprises signing service information, IMSI, the LAI etc. of terminal.

Step 207: the 2nd VLR is during according to the signing service in the described user profile IMS network of having determined terminal unit contractual, indicate the 2nd MSC set up with described AS between grappling concern.

Because terminal moves the back and set up the grappling relation for terminal provides the 2nd MSC of service and AS, therefore, terminal can continue to obtain the IMS subscription professional ability that AS provides in the 2nd MSC control area, guarantees the consistency of terminal unit contractual business.

The 2nd VLR grappling relation between the 2nd MSC foundation and the described AS of indicating specifically comprises:

At first, the 2nd VLR sends the foundation request that is used to indicate the grappling relation between the 2nd MSC foundation and the described AS to the 2nd MSC.

Then, the 2nd MSC initiates register requirement according to the address of the described AS that comprises in the user profile to the AS of correspondence, with the relation of the grappling between foundation and the AS.

The 2nd MSC can obtain user profile from the 2nd VLR, also can be that the 2nd VLR is carried at user profile in the request of foundation, so that the 2nd MSC obtains user profile.

Owing to also comprise the signing service sign in the IMS network in the user profile of terminal, therefore, the 2nd MSC can be carried at the sign of the signing service in the described IMS network in the described register requirement, requires AS to provide the signing service sign in the described IMS network corresponding professional ability for terminal.

Embodiment three:

The embodiment of the invention three is by concrete example, to the detailed description after terminal moves to the 2nd MSC control area from a MSC control area in the embodiment of the invention two.

As shown in Figure 7, the signaling process schematic diagram for the embodiment of the invention three may further comprise the steps:

Step 301: when terminal moves to the 2nd MSC control area, send location update message (Location Update Request) to the 2nd MSC.

Step 302: the 2nd MSC sends the MAP message (MAP LocationUpdate Request) that the position is upgraded to the 2nd VLR.

Step 303: the MAP message that the 2nd VLR upgrades the position sends to the HLR of terminal attaching.

Step 304:HLR sends the MAP message (MAP CancelLocation) of position deletion to a VLR.

Step 305: a VLR sends grappling to a MSC and concerns release message (Cancel).

In the present embodiment, after the one VLR receives MAP Cancel Location message, do not delete the user profile of the terminal of self preserving immediately, concern release message but send grappling to a MSC, request removes because MSC that the business in the IMS network of terminal unit contractual is brought and the relation of the grappling between the AS.

Step 306: a MSC sends de-registration request (Register) to AS, comprises the terminal iidentification of described terminal in this de-registration request.

The one MSC receives after grappling concerns release message, determines the terminal that occurrence positions upgrades according to the terminal iidentification that wherein carries, and this terminal iidentification is included in sends to AS in the de-registration request then.

Step 307:AS carries out the user log off operation to the terminal of described terminal iidentification correspondence, and returns and nullify response message (200OK), and at this moment, the grappling relation between a MSC and the AS discharges.

Step 308: a MSC returns the grappling relation to a VLR and discharges response (Cancel ACK).

Step 309: a VLR receives grappling relation release response back and deletes the user profile of this terminal of self preserving, and deletes the MAP message (MAP Cancel LocationACK) of response to the HLR home position.

After step 310:HLR receives MAP Cancel Location ACK, send insertion subscription data (Insert Subscriber Data, MAP message ISD) (MAP ISD), the user profile of insertion terminal in described ISD message to the 2nd VLR.

In the user profile of present embodiment, comprise IMSI, the LAI of terminal and CAMEL-Subscription-Information etc., CAMEL-Subscription-Information comprises CAMEL-Subscription-Information and terminal the CAMEL-Subscription-Information in flexible exchanging network of terminal in the IMS network, and the CAMEL-Subscription-Information of terminal in the IMS network further is included as address and signing service sign that terminal provides the AS of signing service ability.

Step 311: the 2nd VLR receives and preserves the user profile of terminal, returns the MAP response message (MAP ISD ACK) of ISD then to HLR.

Step 312: the 2nd VLR sends the request of setting up (Set Up) to the 2nd MSC.

The 2nd VLR is by detecting the CAMEL-Subscription-Information in the user profile, signing service in the IMS network of having determined terminal unit contractual, therefore, send the request of foundation, require the 2nd MSC to set up the grappling relation with the AS that the signing service service is provided for terminal according to user profile to the 2nd MSC.

Step 313: after the 2nd MSC confirms to set up the grappling relation with AS, return to the 2nd VLR and to set up request response (Set Up ACK).

Step 314: the 2nd MSC determines corresponding AS according to the address of AS, and then sends register requirement (Register) to AS, with the relation of the grappling between foundation and the AS.

EMSC among three couples of the present invention of the embodiment of the invention two and embodiment has done further perfect, at mobile management feature in IMS network and the flexible exchanging network, make terminal in moving process, also can enjoy the IMS subscription professional ability that AS provides, guaranteed the consistency of terminal traffic.

Embodiment four:

The embodiment of the invention two and embodiment three carry out the mobile management of position when upgrading at terminal, the embodiment of the invention four on the basis of embodiment one, the mobile management when switching at terminal.When terminal switched, business such as traditional voice, data will be handled according to traditional switching flow, can guarantee professional continuity; For the flexible exchanging network business of terminal unit contractual (comprising the professional and charging class business of number analysis class) all when the call setup triggering finish, not influenced by the switching of terminal, but, since terminal unit contractual the signing service in the IMS network, MSC before terminal is switched and AS have the grappling relation in entire I MS process of service execution, when terminal when a MSC control area moves to the 2nd MSC control area, if traditional changing method is not made amendment, just can't guarantee that terminal continues to obtain normal professional ability after switching from AS, particularly for thereby some needs repeatedly to finish the signing service that data are obtained or upgraded alternately with AS in the IMS network, terminal can't continue to obtain professional ability after switching.Data are obtained or the signing service upgraded includes but not limited to presence service thereby described needs are repeatedly finished alternately with AS.Presence service allows terminal initiatively to issue the presence information of self, allows the presence information of other-end inquiry self, perhaps subscribes to the presence information of other-end, and is notified when the presence information of other-end changes.

A kind of changing method that the embodiment of the invention four proposes on the basis of embodiment one exactly, this changing method is by strengthening the interface capability between a MSC and the 2nd MSC, making wins can control the transmission of signaling and/or business datum between MSC and the 2nd MSC, after even terminal moves to the 2nd MSC control area, also can obtain the professional ability of IMS Network by the relation of the grappling between a MSC and the AS.

As shown in Figure 8, the method schematic diagram for the embodiment of the invention four mainly may further comprise the steps:

Step 401: first terminal is according to the scheme of embodiment one, by business in the IMS network of AS and SCP execution terminal unit contractual and the business in the flexible exchanging network.

Step 402: when described terminal in communication process when a MSC control area moves to the 2nd MSC control area, a BSC sends handoff request message to a MSC.

Terminal will periodically report wireless signal to measure message to a BSC when a MSC control area, and wireless signal is measured the signal strength signal intensity that message is used to notify current other BSC that can measure of a BSC terminal.When the wireless signal measurement message that the one BSC basis receives determines that the signal strength signal intensity of the 2nd BSC that terminal is measured is the strongest, determine that terminal will switch to the 2nd BSC.After terminal moves to the 2nd MSC control area, will initiate handoff request to a BSC, a BSC notifies a MSC with this handoff procedure after determining that terminal switches to the 2nd BSC.

Step 403: after a MSC receives handoff request message, determine that according to the 2nd BSC sign of wherein carrying the serving BS broadcasts C after terminal is switched is a BSC, because the 2nd BSC is subjected to the control of the 2nd BSC, therefore, can determine further that terminal moves to the 2nd MSC control area.

Step 404: set up transmission channel between MSC request and the 2nd MSC.

Described transmission channel is used to transmit IMS subscription professional corresponding the control signaling and/or the business datum of terminal.

Step 405: control signaling and/or business datum that a MSC produces when AS is carried out the signing service of terminal send to the 2nd MSC by transmission channel, and receive control signaling and/or business datum from the 2nd MSC by described transmission channel.

Scheme by step 401～step 405, though terminal moves to the 2nd MSC control area by a MSC control area, but the AS of the IMS professional ability that provides for terminal still carries out grappling with a MSC and is connected, control signaling and/or business datum that the IMS subscription business of terminal produces when carrying out will be transmitted by transmission channel, both guaranteed that the grappling relation between an original MSC and the AS was constant, and made terminal can enjoy the professional ability that AS provides incessantly again simultaneously.

Because terminal is after switching to the 2nd MSC control area, traditional business such as its voice, data will switch to the 2nd MSC, therefore, before the step 404 of embodiment four, the one MSC will be released to described terminal distribution channel resource, the 2nd MSC will be the terminal distribution channel resource, and concrete way is:

At first, a MSC sends to the 2nd MSC with handoff request message, and the expression terminal has moved to the 2nd MSC control area.

Then, it is described terminal distribution channel resource that the 2nd MSC indicates the 2nd BSC, and after the 2nd BSC is described terminal distribution channel resource, notifies a MSC.

At last, a MSC determines that terminal has obtained new channel resource after the notice that receives the 2nd MSC transmission, then indicate a BSC to be released to the channel resource of described terminal distribution.

Step 507: the 2nd MSC returns ACM message to a MSC, determines that the 2nd MSC agrees and is ready to connect with a MSC.

Step 508: a MSC returns handoff response (Handover Command) to a BSC, represents that a MSC has carried out switching and prepared.

Step 509: the 2nd BSC send to switch selects (Handover Detect) to the 2nd MSC, and expression is prepared as the terminal distribution channel transmitted resource of eating dishes without rice or wine.

Step 510: the 2nd MSC sends access procedure signal (Process AccessSignalling) to a MSC, is used to notify that a MSC is current is carrying out the process that terminal inserts the 2nd MSC.

Step 511: after the 2nd BSC finishes for the terminal distribution channel resource, return switching to the 2nd MSC and finish (Handover Complete) message.

Step 512: the 2nd MSC transmits completion signal (Send End Signal) to a MSC, and the process that is used to notify a MSC terminal to insert the 2nd MSC is finished.

Step 513: a MSC sends delete command (Clear Command) to a BSC, requires a MSC to be released to the channel resource of described terminal distribution.

Step 514: after a BSC is released to the channel resource of described terminal distribution, return deletion response (Clear Complete) to a MSC.

At this moment, traditional business such as the voice of terminal, data switch to the 2nd MSC, and a MSC has been released to the channel resource of terminal distribution.

Step 515: the 2nd MSC returns ANM to a MSC, represents that the link between a MSC and the 2nd MSC is connected.

Step 516: set up transmission channel between a MSC and the 2nd MSC.

Between a MSC and the 2nd MSC, set up the transmission channel that ability strengthens, be used for IMS subscription professional corresponding the control signaling and/or the business datum of transmission terminal between a MSC and the 2nd MSC.

Step 517～step 518: a MSC carries out the Signalling exchange of IMS subscription business by transmission channel and the 2nd MSC and terminal.

Step 519 and step 520: a MSC continues to carry out the mutual of traffic signaling with AS according to normal mode, and the response message 200OK that AS returns is sent to the 2nd MSC by transmission channel.

Step 521: suppose at first on-hook of terminal, after then the 2nd MSC sent to a MSC with the message of hanging up terminal by transmission channel, a MSC sent release message (REL) to the 2nd MSC.

Step 522: behind the link of the 2nd a MSC dismounting and a MSC, return release response (RLC) to a MSC.

Step 523: after a MSC determines that link is removed, return to the 2nd MSC and to finish response signal (Send End Signal ACK).
