Purpose, technical scheme and advantage for making the embodiment of the present invention is clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, to the embodiment of the present invention in technical scheme be clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention, rather than whole embodiments.Embodiment in based on the present invention, those of ordinary skill in the art
The every other embodiment obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.
The embodiment of the present invention one：
Fig. 1 is the enforcement Organization Chart of the embodiment of the present invention.As can be seen from the figure UE1, UE2, UE3 and UE4 can be noted
Volume can be set up with AS1 and AS2 to CSCF1 or CSCF2, CSCF1 or CSCF2 and is connected.Either MRFC1 or MRFC2,
Can be communicated with MRFP1, MRFP2, MRFP3 and MRFP4, be initiated in calling procedure in UE, AS is needed to be led to MRFC
Letter, it is that caller and called service provide resource to control MRFP by MRFC.CSCF can directly be communicated with MRFC, but for this
For inventive embodiments, the calling and called service of UE must trigger MRFC execution by AS.
Fig. 2 is the flow chart of an embodiment of the method for the present invention, as shown in Fig. 2 the method can include：
S101, resource processing entities send information request message to multiple resource control entities；
It should be noted that when resource processing entities are Multimedia resource function processor (MRFP) MRFP, resource control entity is
Multimedia resource function controller (MRFC) MRFC, or resource processing entities be IP multimedia gateway IM-MGW when, resource control entity is
Multimedia gateway control function MGCF.
Under IMS architecture, MRFC generally has multiple.MRFP with MRFC successful connections after, send information request
Message is to multiple MRFC, it is therefore intended that the state of timing acquisition MRFC, the state of AS and, alternatively, in addition it is also necessary to obtain MRFC
Priority, MRFP needs to select to be registered on specific which or which MRFC according to the information collected.
It should be noted that MRFP can collect request message to MRFC with periodically sending information, the purpose that timing sends is
Ensure within certain cycle can MRFC normal with state be attached, if after in next cycle, timing sends request message
MRFC failures or between link failure, then MRFP can normal with other states MRFC set up and be connected.
Alternatively, MRFP can also send information request message to MRFC, be received by MRFC periodically sending informations
Collect response message to MRFP.
S102, the information response message for receiving the plurality of resource control entity transmission, carry shape in the message
State information, the status information include the status information of the status information and application server AS of resource control entity；Wherein, return
Status information of the status information that returns comprising MRFC, the status information of the corresponding AS of MRFC, alternatively, the status information also includes
The precedence information of MRFC.
If the type that MRFP is configured in initialization procedure can process all users' for load sharing, i.e. each MRFP
All types of business, then also need the priority comprising MRFC in the status information, if MRFP is configured without as load sharing, and
Be arranged to exclusively enjoy, i.e. each MRFP can only process part business, then in the status information need not include MRFC priority,
Only need to the status information of the status information comprising MRFC and the corresponding AS of MRFC.
If MRFC is working properly, the MRFC status informations specially MRFC for returning is working properly；If in a period of time
MRFC does not return status information, then it is assumed that the link failure between MRFC job failures or MRFC and MRFP.Either MRFC
Link failure between failure or MRFC and MRFP itself, it is MRFC work events that MRFP can record the status information of MRFC
Barrier.
The status information of AS is specially that AS is working properly or AS job failures.
Each MRFC has a corresponding priority, and the priority of each MRFC is not mutually equal from high to low.
S103, one or more resource control entities are selected according to the status information, and be registered in the one of the selection
On individual or multiple resource control entities so that one or more resource control entities of the selection trigger the resource process real
Body provides calling and called service for user equipment (UE).
One MRFP can only be registered to a MRFC, it is also possible to be registered to multiple MRFC.Registration can be divided into two kinds：
If 1) type that MRFP is configured in initialization procedure can process all users for load sharing, i.e. each MRFP
All types of business, then MRFP can not be registered in simultaneously on multiple MRFC.Reason is if a MRFP is while be registered to
Multiple MRFC, multiple MRFC use the resource on a MRFP simultaneously, then MRFC can accurately not know that the resource on MRFP makes
Use situation.Also, if a MRFC is used or is notified other MRFC when discharging resource, then the performance meeting of MRFC and MRFP
It is greatly affected.
If 2) MRFP is configured without as load sharing, and is arranged to exclusively enjoy, i.e. each MRFP can only process part business,
If MRFP is by region point, the business of the user of each MRFP process parts region；Or by type of service point, each MRFP process
Partial service type.Then MRFP can be registered on multiple MRFC simultaneously.If reason be each MRFP can only process part business,
Then different business can only be processed on different MRFP, be not in the feelings shared by the multiple MRFP of same business
Condition.Therefore, even if be registered on different MRFC simultaneously, be also not in different MRFC while using the situation of same MRFP.
Before the registration, MRFP need to determine whether MRFC and AS is working properly.MRFP judge MRFC failures or MRFP with
Link failure between MRFC, then will not be registered on the MRFC of failure；MRFC is normal, but between AS failures or MRFC and AS
Link failure, MRFP will not be registered on the MRFC of corresponding A S failure.If it should be noted that the AS more than one of corresponding MRFC
But multiple situations, then all AS all failures just think AS failures, MRFC record AS states are job failure, otherwise it is assumed that AS
Normally, record AS states are working properly.
If MRFP is configured to load sharing, when MRFC and AS is normal, MRFC of the MRFP priority of registration in limit priority
On.If MRFP is not configured to load sharing, i.e., can only process part business, then MRFP can select to register multiple normal
On MRFC, it is not necessary to be registered on the MRFC of highest priority.
By the introduction of the embodiment of the present invention, it can be deduced that MRFP select the constraints importances registered of MRFC from
High to Low be respectively：The priority of MRFC states, AS states and MRFC.The MRFC of normal work is first selected, then from normal work
Its corresponding AS is selected in the MRFC of work working properly, finally again from working properly and corresponding A S MRFC working properly
Select the MRFC of highest priority.MRFP is registered on the MRFC for finally selecting.If it should be noted that MRFP does not match somebody with somebody
Load sharing is set to, then without the concern for priority this constraints of MRFC, i.e.,：Select working properly and corresponding A S work
Make normal MRFC, be registered on one of them or some MRFC, it is also possible to be all registered in the work of working properly and corresponding A S
On normal MRFC.Specifically it is registered on which MRFC or which MRFC, can be determined by data configuration, the present invention is real
Apply example simultaneously unrestricted to this.
When the status information that collects is changed, need to redefine MRFP and be registered on which or which MRFC.Such as
The MRFC of fruit registration is changed, for example：The MRFC failures of registration, or the corresponding AS failures of MRFC, or for Configuration Type be negative
For lotus shares the MRFP of type, the MRFC priority of registration reduces.MRFP in upper once collection status information, according to more than
The constraints of registration, nullifies original MRFC, is registered on new MRFC.
After MRFP is registered in MRFC, UE initiates calling, and call request is first sent to CSCF, and CSCF is controlled by signaling
Agreement (Session Initiation Protocol, SIP) sends " invite " message to AS, triggering AS configuration MRFP and UE
Corresponding relation, and execute the calling and called service of UE.
Corresponding relation lists of the AS according to certain allocation rule configuration MRFP and UE.In embodiments of the present invention, AS can
With the corresponding relation of traffic assignments MRFP of the domain that is located according to UE or customization and UE, releasing from the embodiment of the present invention or
Other similar allocation rules fall within the scope of embodiment of the present invention protection.
For example, UE1, MRFP1 be in Beijing, UE2, MRFP2 in Tianjin, UE3, MRFP3 in Shanghai, UE4, MRFP4 in Shenzhen,
Then, by the traffic assignments of UE1 to MRFP1, the traffic assignments of UE2 are to MRFP2, by the traffic assignments of UE3 to MRFP3, UE4's for AS
Traffic assignments are to MRFP4.Select MRFP services reduce network delay or packet loss by region, improve service quality.Also may be used
So that by business point MRFP, such as MRFP1 is responsible for the call business of the user under CSCF1, and MRFP2 is responsible for the shape of the user under CSCF1
State group message (Presence Group Message, PGM) business；MRFP3 is responsible for the call business of the user under CSCF2,
MRFP4 is responsible for the PGM business of the user under CSCF2, then, to carry out call business, AS is just by UE1's for the UE1 under CSCF1
, to MRFP1, if the UE2 under CSCF1 will carry out PGM business, AS is just by the traffic assignments of UE2 to MRFP2 for traffic assignments.With
Reason, the UE3 under CSCF2 to carry out call business, AS just by the traffic assignments of UE3 to MRFP3, if the UE4 under CSCF2 will enter
Row PGM business, then AS is just by the traffic assignments of UE4 to MRFP4.
It should be noted that all of AS can configure the corresponding relation list of MRFP and UE, an AS under IMS architecture
After having configured corresponding relation list, under IMS architecture, others AS can also update this list, it is therefore an objective to ensure configuration on each AS
Relation list is all unified.
If being responsible for the AS failures for executing calling and called service, CSCF sends a message to other AS working properly, by work
Make the calling and called service that normal AS executes UE, the corresponding relation of AS working properly according to MRFP and UE, by sending
The MRFC of " invite " message to responsible triggering MRFP, so that the corresponding MRFP of MRFC triggering UE provide calling and called service for UE.
The calling and called service can be customized by UE, for example playback, recording etc..
It should be noted that the method for the embodiment of the present invention is can be also used under IMS architecture, IP multimedia gateways are solved
(IP multimedia media gateway, IM-MGW) and MGCF (media gateway control
Function, MGCF) cannot carry out the problem of narrowband calls (PRA callings) after disconnection, and CSCF and AS is not when connecting, AS
Uncontrollable MRFC executes the problem of calling and called service.
IM-MGW is the edge access for realizing IMS and circuit domain (Circuit Switched domain, CS) intercommunication
Layer product.IM-MGW is mainly responsible for IMS domain and is converted to IP modes with the general switching in CS domains, and necessary Codec is compiled
Decoded transform function, so that realize that the whole network IPization communicates.MGCF is the net for making to be communicated between IMS user and CS user
Close.All call control signallings from CS/IMS user all point to MGCF, and it is responsible for carrying out the protocol conversion between agreement, and
Session is transmitted to IMS.MGCF also controls the media channel in IM-MGW.
In the prior art, if IM-MGW is only connected with a MGCF, most basic intercommunication during MGCF failures has
Problem, cannot more trigger calling and called service.
IM-MGW can send state information collection and ask to MGCF, and MGCF sends status information to IM-MGW, the shape
State information includes that the status information of the status information of MGCF and the corresponding AS of MGCF, IM-MGW can be provided by the embodiment of the present invention
Method, select state normal and the normal MGCF of corresponding A S state on.So, the user in CS domains is entered with the user of IMS
During row calling, it can be ensured that the reliability of PSTN network and IMS network intercommunication.
By method provided in an embodiment of the present invention, resource processing entities are according to the shape for receiving each resource control entity transmission
State information is selected and is registered on one or more resource control entities, and when UE initiates calling, resource control entity triggering is right
The resource processing entities that answers complete the calling and called service of UE, solve resource processing entities profit after resource control entity or AS failures
With the low problem of rate, the calling QoS under IMS architecture is improve.
The embodiment of the present invention two：
As shown in figure 3, in the present embodiment, under IMS architecture, the flow process of user's calling is as follows：
S201, MRFP timing sends connection request to multiple MRFC；
The usual more than one of MRFC under IMS architecture.MRFP timings send connection request, it is therefore intended that under IMS architecture
Multiple MRFC obtain connections.The time interval of timing is obtained by the data configuration to MRFP in embodiments of the present invention
's.The embodiment of the present invention is not limited to specific time interval parameter.
S202a, MRFC return connection request response message to MRFP；
After MRFC returns connection request response message, each MRFC is set up with MRFP and is connected.
S202b, MRFC collect the status information of AS；
MRFC sends state collection message to AS.AS after receiving that message, if AS states are normal, return " 200 " and disappears
Breath, if MRFC does not receive " 200 " message, then it is assumed that the link failure between AS failures or AS and MRFC, therefore MRFC record AS
Status information be failure.
It should be noted that S202a and S202b can be executed simultaneously, it is also possible to first carry out S202a, S202b is executed afterwards.
S203, MRFP send information request message to each MRFC；
MRFP sends information request message to each MRFC, it is therefore intended that the state of timing acquisition MRFC, the state of AS
Which which and the priority of MRFC, and select to be registered on specific or MRFC according to the information collected.
S204, MRFP receive the information response message of MRFC returns；
Wherein, status information of the message package of return containing MRFC, the status information of the corresponding AS of MRFC and MRFC's is excellent
First level information.
If MRFC is working properly, the MRFC status informations specially MRFC for returning is working properly；If in a period of time
MRFC does not return status information, then it is assumed that the link failure between MRFC job failures or MRFC and MRFP.Either MRFC
Link failure between failure or MRFC and MRFP itself, it is MRFC work events that MRFP can record the status information of MRFC
Barrier.
The status information of AS is specially that AS is working properly or AS job failures.
Each MRFC has a corresponding priority, and the priority of each MRFC is not mutually equal from high to low.
S205, MRFP determine one or more MRFC, and are registered in one of the determination according to information response message
Or on multiple MRFC；
One MRFP can only be registered to a MRFC, it is also possible to be registered to multiple MRFC.Registration can be divided into two kinds：
If 1) type that MRFP is configured in initialization procedure is the institute that load sharing, i.e. MRFP can process all users
There is the business of type, then MRFP can not be registered on multiple MRFC simultaneously.Reason is if a MRFP is while be registered to multiple
MRFC, multiple MRFC use the resource on a MRFP simultaneously, then MRFC can accurately not know that the resource on MRFP uses feelings
Condition.Also, if a MRFC is used or notified other MRFC when discharging resource, then the performance of MRFC and MRFP can be subject to
Very big impact.
If 2) MRFP is configured without as load sharing, and is arranged to exclusively enjoy, i.e. each MRFP can only process part business,
If MRFP is by region point, the business of the user of each MRFP process parts region；Or by type of service point, each MRFP process
Partial service type.Then MRFP can be registered on multiple MRFC simultaneously.If reason be each MRFP can only process part business,
Then different business can only be processed on different MRFP, be not in the feelings shared by the multiple MRFP of same business
Condition.Therefore, even if be registered on different MRFC simultaneously, be also not in different MRFC while using the situation of same MRFP.
Before the registration, MRFP need to determine whether MRFC and AS is working properly.MRFP judge MRFC failures or MRFP with
Link failure between MRFC, then will not be registered on the MRFC of failure；MRFC is normal, but between AS failures or MRFC and AS
Link failure, MRFP will not be registered on the MRFC of corresponding A S failure.If it should be noted that the AS more than one of corresponding MRFC
But multiple situations, then all AS all failures just think AS failures, otherwise it is assumed that AS is normal.
If MRFP is configured to load sharing, when MRFC and AS is normal, MRFC of the MRFP priority of registration in limit priority
On.If MRFP is not configured to load sharing, i.e., can only process part business, then MRFP can select to register multiple normal
On MRFC, it is not necessary to be registered on the MRFC of highest priority.
By the introduction of the embodiment of the present invention, it can be deduced that MRFP select the constraints importances registered of MRFC from
High to Low be respectively：The priority of MRFC states, AS states and MRFC.The MRFC of normal work is first selected, then from normal work
Its corresponding AS is selected in the MRFC of work working properly, finally again from working properly and corresponding A S MRFC working properly
Select the MRFC of highest priority.MRFP is registered on the MRFC for finally selecting.If it should be noted that MRFP does not match somebody with somebody
Load sharing is set to, then without the concern for priority this constraints of MRFC, that is, selects working properly and corresponding A S work
Make normal MRFC, be registered on one of them or some MRFC, it is also possible to be all registered in the work of working properly and corresponding A S
On normal MRFC.Specifically it is registered on which MRFC or which MRFC, can be determined by data configuration, the present invention is real
Apply example simultaneously unrestricted to this.
When the status data that collects is changed, need to redefine MRFP and be registered on which or which MRFC.Such as
The MRFC of fruit registration is changed, for example：The MRFC failures of registration, or the corresponding AS failures of MRFC, or for Configuration Type be negative
For lotus shares the MRFP of type, the MRFC priority of registration reduces.MRFP in second collection status data, according to more than
The constraints of registration, nullifies original MRFC, is registered on new MRFC.
S206, MRFC send log-on message to CSCF；
After MRFP succeeds in registration, MRFC by registration after information send to CSCF.For example, MRFP1 is registered in MRFC1,
MRFP2 is registered in MRFC2, then MRFC1 can send following message to CSCF1：MRFP_1 is registered in MRFC1, and MRFP2 is unregistered.
MRFC_2 can send following message to CSCF2：MRFP2 is registered in MRFC2, and MRFP1 is unregistered.
S207, UE1 initiate the calling to UE3；
Assume that UE1 is registered on CSCF1, UE3 is registered on CSCF3.UE1 initiates the calling to UE3, and call request passes through
CSCF1 is realizing.After CSCF1 receives the call request of UE1, by signaling control protocol (Session Initiation
Protocol, SIP) " invite " message is sent to AS, AS can be AS1 or AS2, for CSCF1, preferential transmission
" invite " message sends " invite " message to AS2 if AS1 failures to AS1, its object is to trigger AS configuration MRFP with
The corresponding relation list of UE, and execute the calling service of UE1.
S208, AS configure the corresponding relation list of MRFP and UE；
Corresponding relation lists of the AS according to certain allocation rule configuration MRFP and UE, in embodiments of the present invention, AS can
With the corresponding relation of traffic assignments MRFP of the domain that is located according to UE or customization and UE, releasing from the embodiment of the present invention or
Other similar allocation rules fall within the scope of embodiment of the present invention protection.
For example, UE1, MRFP1 be in Beijing, UE2, MRFP2 in Tianjin, UE3, MRFP3 in Shanghai, UE4, MRFP4 in Shenzhen,
Then, by the traffic assignments of UE1 to MRFP1, the traffic assignments of UE2 are to MRFP2, by the traffic assignments of UE3 to MRFP3, UE4's for AS
Traffic assignments are to MRFP4.Select MRFP services reduce network delay or packet loss by region, improve service quality.Also may be used
So that by business point MRFP, such as MRFP1 is responsible for the call business of the user under CSCF1, and MRFP2 is responsible for the shape of the user under CSCF1
State group message (Presence Group Message, PGM) business；MRFP3 is responsible for the call business of the user under CSCF2,
MRFP4 is responsible for the PGM business of the user under CSCF2, then, to carry out call business, AS is just by UE1's for the UE1 under CSCF1
, to MRFP1, if the UE2 under CSCF1 will carry out PGM business, AS is just by the traffic assignments of UE2 to MRFP2 for traffic assignments.With
Reason, the UE3 under CSCF2 to carry out call business, AS just by the traffic assignments of UE3 to MRFP3, if the UE4 under CSCF2 will enter
Row PGM business, then AS is just by the traffic assignments of UE4 to MRFP4.
It should be noted that all of AS can configure the corresponding relation list of MRFP and UE, an AS under IMS architecture
After having configured corresponding relation list, under IMS architecture, others AS can also update this list, it is therefore an objective to ensure configuration on each AS
Relation list is all unified.
S209, AS execute the calling service of UE1；
CSCF1 preferentially sends " invite " message to AS1 by Session Initiation Protocol, triggers the calling service that AS1 executes UE1.If
AS1 does not have failure, then directly execute the calling service of UE1.If AS1 failures, and connect normally, then between CSCF1 and AS2
CSCF1 sends " invite " message to AS2, the calling service for executing UE1 by AS2；If AS1 failures, and between CSCF1 and AS2
Connectionless or connection is abnormal, then CSCF1 routes the call to CSCF2, sends " invite " message to AS2, triggering by CSCF2
AS2 executes the calling service of UE1.
As UE1 is registered on CSCF1, AS1 belongs to CSCF1, then AS1 is the ownership application server of UE1 and AS2 is
The non-attribution application server of UE1.The calling service for triggering UE1 on AS2 has three kinds of methods, can be according to different failure feelings
Condition selects one kind, is respectively：
If the connecting fault 1) between CSCF1 and AS2, and the connection between CSCF1 and CSCF2 also failure when, then
CSCF1 is replied to UE1 and is redirected order, it is desirable to which UE1 initiates calling to CSCF2 again, is sent by CSCF2 " INVITE " message is extremely
AS2, triggers the calling service that AS2 executes UE1；
If 2) connecting fault between CSCF1 and AS2, and connect between CSCF1 and CSCF2 normally, then CSCF 1 is direct
CSCF2 is routed the call to, then CSCF1 sends " INVITE " to AS2, triggering AS2 executes the calling service of UE1 to message；
If 3) connection between CSCF1 and AS2 is normal, directly sent by CSCF1 " INVITE " message to AS2,
Triggering AS2 executes the calling service of UE1.
As AS1 and AS2 are configured with the corresponding relation list of MRFP and UE, in embodiments of the present invention, UE1 and MRFP1
Corresponding, when AS1 executes calling service, AS1 needs to send " invite " message to MRFC1, by MRFC1 by Session Initiation Protocol or
H.248 agreement sends and invites (invite) message to carry out the calling service of UE1 to trigger resource MRFP1；If AS1 failures or
MRFC1 failures, then it is known that MRFP1 is reregistered with MRFC2 from step S201-S205, therefore AS2 sends
" invite " message to MRFC2, by MRFC2 by Session Initiation Protocol or H.248 protocol integrated test system resource MRFP1 carrying out the caller of UE1
Business.
S210, AS execute the called service of UE3；
After completing the calling service of UE1, CSCF1 routes the call to CSCF2.According to domain name or other modes point
Match somebody with somebody, UE3 is corresponding with MRFP3.By Session Initiation Protocol or H.248 therefore AS2, by notifying MRFC2, by MRFC2, protocol integrated test system MRFP3 enters
The called service of row UE3.Even if this ensures that thering MRFC1 or AS1 failures, the calling and called service triggering of UE is not subject to shadow
Ring.
If it should be noted that AS2 or MRFC2 failures, it is known that MRFP3 is noted again from step S201-S205
Volume needs, in MRFC1, the called service for being executed UE3 by AS1.UE3 is registered in CSCF2, and AS1 belongs to CSCF1, therefore AS1 is
The non-attribution application server of UE3, CSCF2 execute the quilt of UE3 by one of three kinds of methods described in similar S209 to trigger AS1
It is business.After receiving the triggering message of CSCF2, AS1 sends " invite " message to MRFC1, passes through Session Initiation Protocol by MRFC1
Or H.248 protocol integrated test system resource MRFP3 carrying out the called service of UE3.
S211, UE complete call operation.
AS triggers the calling and called service of UE, and the calling between UE1 and UE3 is connected, and proceeds by call operation.
It should be noted that the method for the embodiment of the present invention is can be also used under IMS architecture, solve IM-MGW and MGCF and break
When cannot carry out the problem of narrowband calls (PRA callings) after even, and solve CSCF and AS and do not connect, the uncontrollable MRFC of AS
Execute the problem of calling and called service.
IM-MGW can send state information collection and ask to MGCF, and MGCF sends status information to IM-MGW, the shape
State information includes that the status information of the status information of MGCF and the corresponding AS of MGCF, IM-MGW can be provided by the embodiment of the present invention
Method, select state normal and the normal MGCF of corresponding A S state on.So, the user in CS domains is entered with the user of IMS
During row calling, it can be ensured that the reliability of PSTN network and IMS network intercommunication.Main quilt is provided under the IMS architecture that the present embodiment is provided
The method for being business, multiple MRFP are selected and are registered on MRFC according to the status information for receiving each MRFC transmissions, and AS is configured
The corresponding relation list of MRFC and MRFP, when UE initiates calling, MRFC triggers the calling and called that corresponding MRFP resources complete UE
After business, call establishment, after solving the problems, such as MRFC or AS failures, MRFP utilization rates are low, improve the calling under IMS architecture
QoS.
The embodiment of the present invention three：
The embodiment of the present invention provides a kind of resource processing entities, as shown in figure 4, including：
Transmitting element 301, for sending information request message to multiple resource control entities；
It should be noted that when resource processing entities are Multimedia resource function processor (MRFP) MRFP, resource control entity is
Multimedia resource function controller (MRFC) MRFC, or resource processing entities be IP multimedia gateway IM-MGW when, resource control entity is
Multimedia gateway control function MGCF.Under IMS architecture, MRFC generally has multiple.MRFP with MRFC successful connections after, send out
Send unit 301 send information ask to multiple MRFC, it is therefore intended that the state of timing acquisition MRFC, the state of AS and,
Alternatively, in addition it is also necessary to obtain the priority of MRFC, MRFP need according to the information that collects select to be registered in specific which
Or on which MRFC.
It should be noted that transmitting element 301 can collect request message to MRFC with periodically sending information, timing sends
Purpose be ensure within certain cycle can MRFC normal with state be attached, if timing sends request in next cycle
After message MRFC failures or between link failure, then MRFP can normal with other states MRFC set up and be connected.
Alternatively, transmitting element 301 can also send information request message to MRFC, be sent by MRFC timings
The receiving unit of information response message to MRFP.
Receiving unit 302, for receiving the information response message that the plurality of resource control entity sends, described disappears
Carrier state information in breath, the status information include the state letter of the status information and application server AS of resource control entity
Breath；
Wherein, status information of the status information that receiving unit 302 is received comprising MRFC, the state of the corresponding AS of MRFC
Information, alternatively, the status information also precedence information comprising MRFC.
If the type that MRFP is configured in initialization procedure can process all users' for load sharing, i.e. each MRFP
All types of business, then also need the priority comprising MRFC in the status information, if MRFP is configured without as load sharing, and
Be arranged to exclusively enjoy, i.e. each MRFP can only process part business, then in the status information need not include MRFC priority,
Only need to the status information of the status information comprising MRFC and the corresponding AS of MRFC.
If MRFC is working properly, the MRFC status informations specially MRFC for returning is working properly；If in a period of time
MRFC does not return status information, then it is assumed that the link failure between MRFC job failures or MRFC and MRFP.Either MRFC
Link failure between failure or MRFC and MRFP itself, it is MRFC work events that MRFP can record the status information of MRFC
Barrier.
The status information of AS is specially that AS is working properly or AS job failures.
Each MRFC has a corresponding priority, and the priority of each MRFC is not mutually equal from high to low.
Select unit 303, for selecting one or more resource control entities according to the status information；
It should be noted that the Configuration Type of MRFP can be divided into two kinds：
If 1) type that MRFP is configured in initialization procedure can process all users for load sharing, i.e. each MRFP
All types of business, then the registering unit of MRFP can not be registered in simultaneously on multiple MRFC.Reason is if a MRFP
Multiple MRFCs are registered to simultaneously, and multiple MRFC use the resource on a MRFP simultaneously, then MRFC can accurately not know MRFP
On resource service condition.Also, if MRFC is used or is notified other MRFC during release resource, then MRFC and
The performance of MRFP can be greatly affected.
If 2) MRFP is configured without as load sharing, and is arranged to exclusively enjoy, i.e. each MRFP can only process part business,
If MRFP is by region point, the business of the user of each MRFP process parts region；Or by type of service point, each MRFP process
Partial service type.Then the registering unit of MRFP can be registered on multiple MRFC simultaneously.If reason is each MRFP can only locate
Partial service is managed, then different business can only be processed on different MRFP, be not in that the multiple MRFP of same business enter
The situation that row is shared.Therefore, even if be registered on different MRFC simultaneously, be also not in different MRFC while using same
The situation of MRFP.
Before select unit 303 selects MRFC, need to determine whether MRFC and AS is working properly.The judging unit of MRFP is sentenced
Disconnected MRFC failures or the link failure between MRFP and MRFC, then select unit 303 will not select the MRFC of failure；MRFC is just
Often, the link failure but between AS failures or MRFC and AS, select unit 303 will not also select the MRFC of corresponding A S failure.Need
If it is noted that the AS more than one of corresponding MRFC but multiple situations, all AS all failures just think AS failures,
MRFC record AS states are job failure, otherwise it is assumed that AS is normal, MRFC record AS states are working properly.
If MRFP is configured to load sharing, when MRFC and AS is normal, 303 prioritizing selection limit priority of select unit
MRFC.If MRFP is configured to exclusively enjoy, i.e., can only process part business, then select unit 303 can select multiple normal MRFC,
The MRFC of highest priority need not be selected.
Registering unit 304, for being registered in the MRFC of the selection, so that the MRFC of the selection triggers the MRFP
Calling and called service is provided for user equipment (UE).
Registering unit 304 is registered on the MRFC of the selection of select unit 303.When the data that collects are changed, select
Unit 303 needs to reselect MRFC.If the MRFC of the registration of registering unit 304 is changed, such as：The MRFC failures of registration,
Or the corresponding AS failures of MRFC, or for MRFP of the Configuration Type for load sharing type, the registration of registering unit 304
MRFC priority reduces.Registering unit 304, is nullified according to the constraints that registers above in upper once collection status information
Former MRFC, is registered on new MRFC.
After registering unit 304 is registered in MRFC, UE initiates calling, and call request is first sent to CSCF, and CSCF passes through
Session Initiation Protocol sends " invite " message to AS, triggers the corresponding relation of AS configuration MRFP and UE, and executes the calling and called industry of UE
Business.
Corresponding relation lists of the AS according to certain allocation rule configuration MRFP and UE.In embodiments of the present invention, AS can
With the corresponding relation of traffic assignments MRFP of the domain that is located according to UE or customization and UE, releasing from the embodiment of the present invention or
Other similar allocation rules fall within the scope of embodiment of the present invention protection.
For example, UE1, MRFP1 be in Beijing, UE2, MRFP2 in Tianjin, UE3, MRFP3 in Shanghai, UE4, MRFP4 in Shenzhen,
Then, by the traffic assignments of UE1 to MRFP1, the traffic assignments of UE2 are to MRFP2, by the traffic assignments of UE3 to MRFP3, UE4's for AS
Traffic assignments are to MRFP4.Select MRFP services reduce network delay or packet loss by region, improve service quality.Also may be used
So that by business point MRFP, such as MRFP1 is responsible for the call business of the user under CSCF1, and MRFP2 is responsible for the PGM of the user under CSCF1
Business；MRFP3 is responsible for the call business of the user under CSCF2, and MRFP4 is responsible for the PGM business of the user under CSCF2, then
, to carry out call business, AS is just by the traffic assignments of UE1 to MRFP1 for UE1 under CSCF1, if the UE2 under CSCF1 will be carried out
PGM business, then AS is just by the traffic assignments of UE2 to MRFP2.In the same manner, the UE3 under CSCF2 just will to carry out call business, AS
The traffic assignments of UE3 are to MRFP3, if the UE4 under CSCF2 will carry out PGM business, the traffic assignments of UE4 are just given by AS
MRFP4.
It should be noted that all of AS can configure the corresponding relation list of MRFP and UE, an AS under IMS architecture
After having configured corresponding relation list, under IMS architecture, others AS can also update this list, it is therefore an objective to ensure configuration on each AS
Corresponding relation list is all unified.
If being responsible for the AS failures for executing calling and called service, CSCF sends a message to other AS working properly, by work
Make the calling and called service that normal AS executes UE, the corresponding relation of AS working properly according to MRFP and UE, by sending
" invite " message is to the corresponding MRFC of MRFP, so that the corresponding MRFP of MRFC triggering UE provide calling and called service for UE.
It should be noted that the device of the embodiment of the present invention can also be solved under IMS architecture, after IM-MGW and MGCF disconnections
When cannot carry out the problem of narrowband calls (PRA callings), and solve CSCF and AS and do not connect, the uncontrollable MRFC of AS are executed
The problem of calling and called service.
The transmitting element of IM-MGW can send state information collection and ask to MGCF, MGCF by status information send to
The receiving unit of IM-MGW, the status information include the status information of the status information of MGCF and the corresponding AS of MGCF, IM-MGW
Select unit select state normal and the normal MGCF of corresponding A S state, IM-MGW registering unit is registered in the MGCF
On.When the user in CS domains is called with the user of IMS, it can be ensured that the reliability of PSTN network and IMS network intercommunication.
By resource processing entities provided in an embodiment of the present invention, receiving unit receives the shape that each resource control entity sends
State information, select unit select resource control entity, registering unit to be registered on the resource control entity of select unit selection,
When UE initiates calling, resource control entity triggers corresponding resource and processes the calling and called service that actual resource completes UE, solves
After resource control entity or AS failures, resource processes the low problem of entity utilization, improves the calling QoS under IMS architecture.
The embodiment of the present invention four：
The embodiment of the present invention also provides the system for providing calling and called service under a kind of IMS architecture, as shown in figure 5, including：
Resource processing entities 401, multiple to Multimedia resource function controller (MRFC) for sending information request message
MRFC, receives the information response message that the plurality of resource control entity sends, carrier state information in the message, institute
Stating status information includes the status information of status information and application server AS of resource control entity, according to the status information
One or more resource control entities are selected, and is registered on one or more resource control entities of the selection, so that institute
The one or more resource control entities for stating selection trigger the resource processing entities and provide calling and called service for user equipment (UE)；
It should be noted that when resource processing entities are Multimedia resource function processor (MRFP) MRFP, the resources control reality
Body be Multimedia resource function controller (MRFC) MRFC, or resource processing entities be IP multimedia gateway IM-MGW when, the resource control
Entity processed is multimedia gateway control function MGCF.Under IMS architecture, MRFC generally has multiple.MRFP is being connected into MRFC
After work(, send information and ask to each MRFC, it is therefore intended that the state of acquisition MRFC, the state of AS and MRFC's is excellent
First level, and select to be registered on specific which or which MRFC according to the information collected.
It should be noted that MRFP can collect request message to MRFC with periodically sending information, the purpose that timing sends is
Ensure within certain cycle can MRFC normal with state be attached, if after in next cycle, timing sends request message
MRFC failures or between link failure, then MRFP can normal with other states MRFC set up and be connected.
The status information that MRFP is received includes the status information of MRFC, the status information of the corresponding AS of MRFC and optional
Ground, the precedence information of MRFC.
If the type that MRFP is configured in initialization procedure can process all users' for load sharing, i.e. each MRFP
All types of business, then also need the priority comprising MRFC in the status information, if MRFP is configured without as load sharing, and
Be arranged to exclusively enjoy, i.e. each MRFP can only process part business, then in the status information need not include MRFC priority,
Only need to the status information of the status information comprising MRFC and the corresponding AS of MRFC.
If MRFC is working properly, the MRFC status informations specially MRFC for returning is working properly；If in a period of time
MRFC does not return status information, then it is assumed that the link failure between MRFC job failures or MRFC and MRFP.Either MRFC
Link failure between failure or MRFC and MRFP itself, it is MRFC work events that MRFP can record the status information of MRFC
Barrier.
The status information of AS is specially that AS is working properly or AS job failures.
Each MRFC has a corresponding priority, and the priority of each MRFC is not mutually equal from high to low.
The Configuration Type of MRFP can be divided into two kinds：
If 1) type that MRFP is configured in initialization procedure is the institute that load sharing, i.e. MRFP can process all users
There is the business of type, then MRFP can not be registered on multiple MRFC simultaneously.Reason is if a MRFP is while be registered to multiple
MRFC, multiple MRFC use the resource on a MRFP simultaneously, then MRFC can accurately not know that the resource on MRFP uses feelings
Condition.Also, if a MRFC is used or notified other MRFC when discharging resource, then the performance of MRFC and MRFP can be subject to
Very big impact.
If 2) MRFP is configured without as load sharing, and is arranged to exclusively enjoy, i.e. each MRFP can only process part business,
If MRFP is by region point, the business of the user of each MRFP process parts region；Or by type of service point, each MRFP process
Partial service type.Then MRFP can be registered on multiple MRFC simultaneously.If reason be each MRFP can only process part business,
Then different business can only be processed on different MRFP, be not in the feelings shared by the multiple MRFP of same business
Condition.Therefore, even if be registered on different MRFC simultaneously, be also not in different MRFC while using the situation of same MRFP.
Before MRFP selects MRFC, need to determine whether MRFC and AS is working properly.The judgement MRFC failures of MRFP or
Link failure between MRFP and MRFC, then will not select the MRFC of failure；MRFC is normal, but between AS failures or MRFC and AS
Link failure, MRFP will not also select the MRFC of corresponding A S failure.If it should be noted that the AS more than one of corresponding MRFC
But multiple situations, then all AS all failures just think AS failures, MRFC record AS states are job failure, otherwise it is assumed that AS
Normally, MRFC record AS states are working properly.
If MRFP is configured to load sharing, when MRFC and AS is normal, the MRFC of MRFP prioritizing selection limit priorities.If
MRFP is configured to exclusively enjoy, i.e., can only process part business, then MRFP can select multiple normal MRFC, it is not necessary to select preferential
Level highest MRFC.
MRFP is registered on the MRFC of selection.When the data that collects are changed, MRFP needs to reselect MRFC.Such as
The MRFC of fruit registration is changed, for example：The MRFC failures of registration, or the corresponding AS failures of MRFC, or for Configuration Type be negative
For lotus shares the MRFP of type, the MRFC priority of MRFP registrations reduces.MRFP in upper once collection status information, according to
The constraints of above registration, nullifies original MRFC, is registered on new MRFC.
After MRFP is registered on MRFC, UE initiates calling, and call request is first sent to CSCF, and CSCF is assisted by SIP
View sends " invite " message to AS, triggers the corresponding relation list of AS configuration MRFP and UE, and executes the calling and called service of UE.
Corresponding relation lists of the AS according to certain allocation rule configuration MRFP and UE.In embodiments of the present invention, AS can
With the corresponding relation of traffic assignments MRFP of the domain that is located according to UE or customization and UE, releasing from the embodiment of the present invention or
Other similar allocation rules fall within the scope of embodiment of the present invention protection.
For example, UE1, MRFP1 be in Beijing, UE2, MRFP2 in Tianjin, UE3, MRFP3 in Shanghai, UE4, MRFP4 in Shenzhen,
Then, by the traffic assignments of UE1 to MRFP1, the traffic assignments of UE2 are to MRFP2, by the traffic assignments of UE3 to MRFP3, UE4's for AS
Traffic assignments are to MRFP4.Select MRFP services reduce network delay or packet loss by region, improve service quality.Also may be used
So that by business point MRFP, such as MRFP1 is responsible for the call business of the user under CSCF1, and MRFP2 is responsible for the shape of the user under CSCF1
State group message (Presence Group Message, PGM) business；MRFP3 is responsible for the call business of the user under CSCF2,
MRFP4 is responsible for the PGM business of the user under CSCF2, then, to carry out call business, AS is just by UE1's for the UE1 under CSCF1
, to MRFP1, if the UE2 under CSCF1 will carry out PGM business, AS is just by the traffic assignments of UE2 to MRFP2 for traffic assignments.With
Reason, the UE3 under CSCF2 to carry out call business, AS just by the traffic assignments of UE3 to MRFP3, if the UE4 under CSCF2 will enter
Row PGM business, then AS is just by the traffic assignments of UE4 to MRFP4.
It should be noted that all of AS can configure the corresponding relation list of MRFP and UE, an AS under IMS architecture
After having configured corresponding relation list, under IMS architecture, others AS can also update this list, it is therefore an objective to ensure configuration on each AS
Relation list is all unified.
If being responsible for the AS failures for executing calling and called service, CSCF sends a message to other AS working properly, by work
Make the calling and called service that normal AS executes UE, the corresponding relation of AS working properly according to MRFP and UE, by sending
" invite " message is to the corresponding MRFC of MRFP, so that the corresponding MRFP of MRFC triggering UE provide calling and called service for UE.
The resource control entity, for receiving the collection solicited message that the resource processing entities send, sends information
Response message is collected to the resource processing entities, carrier state information in the message receives the resource processing entities
Register, and trigger the resource processing entities calling and called service is provided for user equipment (UE).
Before MRFC receives the collection solicited message that MRFP sends, the status information of AS is first got, method is as follows：Send
State collection information is to AS, if AS returns " 200 " message, AS states are normal, if not returning AS states in a period of time,
Think that the connecting fault between AS failures or AS and MRFC, MRFC record the state of AS.
During MRFC encapsulates the status information of the status information of itself, precedence information and AS to response message, concurrently
Deliver in MRFP.
After the registration request for receiving MRFP, MRFC receives the registration of MRFP.And after UE initiates calling, receive AS
" invite " message for sending, triggering MRFP provide calling service for UE.
It should be noted that the system of the embodiment of the present invention is can be also used under IMS architecture, after IM-MGW and MGCF disconnections
When cannot carry out the problem of narrowband calls (PRA callings), and solve CSCF and AS and do not connect, the uncontrollable MRFC of AS are executed
The problem of calling and called service.
IM-MGW can send state information collection and ask to MGCF, and MGCF sends status information to IM-MGW, the shape
State information includes that the status information of the status information of MGCF and the corresponding AS of MGCF, IM-MGW can be provided by the embodiment of the present invention
Method, select state normal and the normal MGCF of corresponding A S state on.So, the user in CS domains is entered with the user of IMS
During row calling, it can be ensured that the reliability of PSTN network and IMS network intercommunication.
