Embodiment

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

The ISC interface adaption function:

If the business of terminal unit contractual only limits to soft switch service, 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, by newly-increased ISC interface adaptation module, the AS that the IMS business of terminal request is toggled in the IMS network is processed.

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 in IMS AS.

The Diameter function:

Be optional function, be used for the signaling of identification, translation 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 synchronizing capacity, the information of terminal unit contractual IMS Network may only be kept in HSS, does 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 to HSS, obtain the signing service sign of terminal in the IMS network, thereby finishing service triggers flow process.

Enhance?Call?Control：

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

EMSC in the embodiment of the present 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 by the intercommunications on the EMSC practical function.

Can realize the intercommunication of IMS network and flexible exchanging network due to the EMSC of embodiment of the present invention proposition, compare with the ICS framework, less to the transformation amount of network, do not need additionally to build TAS to realize the support to telecommunication service; Simultaneously, therefore the business of EMSC in the embodiment of the present invention in can also the executive software switching network guaranteed the consistency of business, and, avoid under the ICS structure service needed in flexible exchanging network by IMS network route, solved the problem of signaling process complexity.

Embodiment one:

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

In the present embodiment one, suppose that current terminal is positioned at a MSC control area, the present embodiment one provide signing service professional ability method as shown in Figure 5, comprise the following 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 the signing service in the described signing service information IMS network of having determined described terminal unit contractual and the signing service in 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 flexible exchanging network.In the present embodiment, the signing service information of terminal comprises: the signing service information in the IMS network and the signing service information in flexible exchanging network.

Step 103: extract the signing service sign in application server (AS) address and 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, AS address indication 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 described AS AS corresponding to address.

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 signing.After the service request that the one MSC will comprise the signing service sign in the IMS network sends to AS, namely and set up the grappling relation between AS, AS is considered as S-CSCF in the IMS network with a MSC, and the professional ability of the corresponding business of signing service sign in the IMS network is provided for terminal.

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

Signing service information in 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 (Terminating CAMEL SubscriptionInformation, T-CSI) that triggers as called end of terminal and one or more in the number segment trigger message.If comprise O-CSI in the signing service information in flexible exchanging network, O-CSI comprises the signing service sign of at least one business; If comprise O-CSI in the signing service information in flexible exchanging network, 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 that represents 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 flexible exchanging network sends to SCP corresponding to SCP address.

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

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

In the scheme of the embodiment of the present 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, have due to a MSC on the basis of soft switch service disposal ability and also have simultaneously the IMS traffic handing capacity, therefore, carry out simultaneously soft switch service and IMS business in the situation that allow 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 the 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.

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

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

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

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

Can for the signing service in the IMS network and the setting of the signing service in flexible exchanging network priority, when determining to clash between multi-service, can carry out successively the business that clashes according to priority order from high to low in this method.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 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 present 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 present invention is also considered terminal in flexible exchanging network different mobile management feature in IMS network and flexible exchanging network, proposition is at the net 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 namely 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: change for terminal provides the MSC of service to change constantly along with the position of terminal in flexible exchanging network.

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

Embodiment two:

A MSC in 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 fast mobile terminal, the 2nd MSC is the purpose MSC after fast mobile terminal, the first base station controller (BSC) is the network element that is subjected to a MSC to control and is connected with a MSC with being connected 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 arrange respectively.

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

The embodiment of the present invention two is a kind of updating of terminal position schemes that propose on the basis of embodiment one, and after making terminal move to the 2nd MSC control area from a MSC control area, 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 present invention two comprises the following steps:

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

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

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

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

The HLR that relates in 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, send position deletion message to a VLR, require the user profile of the terminal of a VLR deletion storage.。

Step 204: after a VLR receives described position deletion message, the grappling relation between indication the one MSC release and described AS.

The concrete grammar of the grappling relation between the one VLR indication the one MSC release and AS is:

At first, a VLR sends grappling to a MSC and concerns release message, requires a MSC to be released to described terminal and the grappling relation set up with AS.

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 de-registration request to terminal, and at this moment, the grappling relation between a MSC and AS discharges, and AS returns to the cancellation response message to a MSC, the event that notice grappling relation discharges.

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

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

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

Deleted the user profile of terminal due to a VLR, therefore, HLR requires to preserve the user profile of terminal for terminal provides the 2nd VLR of service after fast mobile terminal.

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, indication the 2nd MSC set up and described AS between the grappling relation.

Owing to having set up the grappling relation for terminal provides the 2nd MSC of service and AS after fast mobile terminal, 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.

Grappling relation between the 2nd VLR indication the 2nd MSC foundation and described AS 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 described AS to the 2nd MSC.

Then, the 2nd MSC is according to the address of the described AS that comprises in user profile, to the AS initiation registration request of correspondence, with the grappling relation between foundation and AS.

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

Due to the signing service sign that also comprises in the user profile of terminal in the IMS network, therefore, the 2nd MSC can be carried at the sign of the signing service in described IMS network in described registration request, requires AS that the ability of the corresponding business of signing service sign in described IMS network is provided for terminal.

Embodiment three:

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

As shown in Figure 7, the signaling process schematic diagram for the embodiment of the present invention three comprises the following steps:

Step 301: during fast mobile terminal to the two MSC control area, send location update message (Location Update Request) to the 2nd MSC.

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

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 immediately the user profile of the terminal of self preserving, concern release message but send grappling to a MSC, the MSC that brings due to the business in the IMS network of terminal unit contractual and the grappling relation between AS are removed in request.

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

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

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

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

Step 309: a VLR deletes the user profile of this terminal of self preserving after receiving grappling relation release response, 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 to the 2nd VLR and insert subscription data (Insert Subscriber Data, ISD) MAP message (MAP ISD), the user profile of insertion terminal in described ISD message.

Comprise IMSI, the LAI of terminal and CAMEL-Subscription-Information etc. in the user profile of the present embodiment, CAMEL-Subscription-Information comprises CAMEL-Subscription-Information and the terminal 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, then returns to the MAP response message (MAP ISD ACK) of ISD 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 user profile, signing service in the IMS network of having determined terminal unit contractual, therefore, send to the 2nd MSC the request of foundation, require the 2nd MSC to set up the grappling relation according to user profile with the AS that the signing service service is provided for terminal.

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

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