When asking SIP service from terminal 102, the user of request SIP service is identified as sip：john.smith@my-
company.nl.Form of the public user identity symbol with universal resource identifier (URI) of SIP service.Identify followingly
Location composition.Pattern " sip：" indicate to request SIP service.The agreement for routing the request to purpose place should be SIP.Domain
(e.g., the user that " my-company.nl " is used to export as request SIP service provides the IMS network of service
ims.provider.nl).This causes can be according to DNS service and SIP method for routing, to IMS network user route SIP clothes
Business request.User Part " john.smith " is combined with domain identifies the specific use that (as derived from domain) IMS network is serviced
Family.In the ims network, SIP service request is forwarded to (e.g., the s- of registration office (S-CSCF) 6 for being currently assigned to the user
cscfl.ims.provider.nl).When SIP request is forwarded to registration office 6, the contact that can be also included based on registration office
Address information (e.g., sip：173.68.81.221), user terminal is further transferred it to.
When SIP client 16 sends SIP request to the IMS subscriber associated with UE 102, specific to SIP service, have
The three steps forwarding of SIP request.It is easy to set up SIP service to the terminal 102 of IMS subscriber.Each step of three steps forwarding
It is all based on including the database of either statically or dynamically data.It is used to build using termination extension used in three relations to Current subscriber
The initial request of vertical multimedia communication sessions (e.g., inviting), or non-session association requests (e.g., message).First, using pair
Invitation from the SIP client 16 for initiating SIP sessions is expanded to and gone to as domain my- by the DNS query of dns server
In company.nl any subscriber (<user>@my-company.nl) IMS network serviced is provided.DNS constitutes global
DNS infrastructure and including outside DNS and inside DNS.The route based on DNS of being somebody's turn to do invited is configured based on static state DNS.Second,
In service subscriber<user>In@my-company.nI IMS network, inquired about using the HSS 8 of I-CSCF entities 10 and invite this
Expand to current registration office's S-CSCF entities 6 that service is provided for subscriber john.smith@my-company.nl.For this
The data of extension are dynamic datas, included in HSS 8, and when subscriber's cancel register or another S-CSCF entity 6 are assigned
Updated during to subscriber john.smith@my-company.nl.3rd, bound from S-CSCF entities 6 using SIP contact persons by pin
Extend to that subscriber John Smith currently register to subscriber john.smith@my-company.nl invitation is one or more
Terminal 102.Contact person's binding information is dynamic, is updated when such as terminal 102 changes IP accesses.
As described, present subscriber John Smith are now ready for receiving the request of SIP session establishments that (e.g., SIP is invited
Please) or non-session correlation SIP transactions requests (e.g., sip message).
Inventor recognizes that subscriber will be from its multimedia terminal in addition to the possibility that prior art network 101 is provided
Benefit in the possibility that additional IP services are provided, the IP services can be accessed by third party.It was recognized by the inventor that for example subscriber wishes

Fig. 6 is examined, it illustrates the flow chart for including the job step on Fig. 4 networks 1 illustrated.
There are subscriber active 202 and 3 IP of work to be served by his (movement) multimedia equipment 2.First IP
It is sip user agent 18 to be served by, and it is used to set up and receives SIP sessions or SIP isolated (stand-alone) request.Should
Sip user agent 18 is activated in IMS registration.Pass through IMS network, such as P-CSCF entities and S- well known in the prior art
CSCF, accesses the sip user agent 18.2nd IP is served by being FTP service application 20B, and it can be activated at any time when needed.
The IP access networks 4 used by the subscriber associated with multimedia equipment 2 access FTP service application 20B.3rd IP services should
With for HTTP service application 20A, it can be activated at any time when needed.Used by the subscriber associated with multimedia equipment 2
IP access networks 4 access HTTP service application 20A.
According to prior art, it is contemplated that DNS includes the domain john.smith.my- associated with subscriber John Smith
company.nl.So as to (that is, it needs to service visitor by IP needed for being served by using the IP in the IMS equipment 2 for accessing subscriber
DNS resolver in family end 16 is obtained) DNS resource records, (public) official DNS name servers 14 in the domain are carried out
Configuration.The problem of static configuration is, this configuration of DNS name servers 14 is static, and the IP address of the equipment 2 of subscriber
It is dynamic.Also, subscriber can dispose one or more IP on his multimedia equipment 2 and be served by.When needs
Wait, the IP that subscriber can activate or deactivate in his equipment 2 is served by.On (static state) DNS name servers 14 not
Can configuration this flexible activation and deactivation.Also, subscriber should have to he equipment 2 addition IP be served by and from he
Equipment 2 in remove the possibility that is served by of IP.This flexible IP clothes can not be configured on (static state) DNS name servers 14
Business application addition and removal.Herein it should be noted that the dynamic in IETF RFC 2136, domain name system updates (DNS
UPDATE) describe how to update (public) dns server.Specifically, IETF RFC 2136 define an agreement, root
According to the agreement, entity can update the DNS resource records in dns server.The renewal of these resource records is static.This is just
Strengthen problems as mentioned above, that is, subscriber must continually update (public) dns server.Whenever subscriber obtains
During new IP address for equipment 2, or when being served by subscriber activation or the IP deactivated in his equipment 2, or
Person is added or removed in his equipment 2 when IP is served by, it is necessary to update whenever subscriber.
These problems are solved by providing 204 DNS services 22 performed in equipment 2.The domain of subscriber will be related to (i.e.,
Domain john.smith.my-company.nl) DNS query forwarding 222,224,226 arrive subscriber device 2.Subscriber device 2 is by cloth
It is set to the DNS service 22 for being performed thereon and being related to the domain associated with the subscriber.Subscriber device 2 also stores 206 and is related to DNS resources
The information of record, the resource record is to access the IP just performed in equipment 2 at that time to be served by needed for 20A and 20B.
Therefore, perform DNS service 204 is subscriber's multimedia equipment 2, i.e., for the domain for the user for being related to equipment 2, equipment
2 act as the role of dns server 22 '.Because will be with the time without with the case of, dynamically installing and moving in IP address
Remove, activate and deactivate that IP is served by 20A, 20B is subscriber's multimedia equipment 2.Therefore, it is that the equipment 2 is most preferably matched somebody with somebody
It is standby to provide and the available IP information that to be served by 20A, 20B relevant in equipment 2.
Described above with reference to Fig. 2 and terminal 102 is registered to IP network 101.For being registered to IMS network 1, the registration
Performed by equipment 2.
During registering, equipment 2 also deposits the instruction of its ability for performing DNS service.Deposited according in S-CSCF entities 6
Contact person's binding is put for the principle of SIP service, equipment 2 is deposited " dns server binding " in IMS network 1.In the figure 7
Description thereof.According to IMS specifications, contact person's binding that SIP service is deposited in S-CSCF entities 6, therefore no longer describe.Dotted line
112 represent the contact address for the SIP service of the public user identity being stored in registration office 6.Dotted line 312 is represented pin
The contact address of the DNS service of the public user identity is stored in HSS 8.
The instruction that equipment performs DNS service ability is included in (shielded) SIP registration message 213, and is stored in
In HSS 8.The instruction, which is included in from S-CSCF to HSS 8, to be sent in 216 Diameter server assignment request SAR 215.
According to IMS standards, Diameter SAR can carry the copy of complete SIP registration message, including equipment performs DNS service ability
Instruction.The instruction is alignd with the validity of time with the IMS registration of equipment 2.When the IMS registration of equipment 2 it is expired failure or
During equipment cancel register, the instruction that equipment performs DNS service ability is removed.Therefore, the receiving devices of HSS 8 perform DNS service energy
The instruction of power.(need not) know that the practical IP activated in equipment 2 is served by 20A and 20B to HSS 8 yet.The instruction includes
The network address of the DNS service 22 performed in equipment 2.Therefore, the network of the DNS service 22 performed in the storage devices 2 of HSS 8
Address.
The instruction that the equipment that equipment 2 is provided to HSS 8 performs the ability of DNS service can including being inquired about for local dns
The IP address of the DNS service performed on the multimedia equipment 2 of arrival.The IP address can be that equipment 2 is received in IMS registration
The IP address for secure accessing IMS network.The IP address for being used for secure accessing IMS network is IP on P-CSCF 5
Location.Therefore, DNS query to equipment 2 will be route to equipment 2 by P-CSCF 5, P-CSCF5 will be forwarded by secure connection
DNS query.
To make P-CSCF 5 forward DNS query to subscriber device 2, P-CSCF 5 will can by DNS query with it is specific
Registering subscriber is associated.Therefore, when the IMS registration from subscriber includes the instruction for the ability that equipment performs DNS service, P-
CSCF 5 stores the instruction in the subscriber profiles of subscriber.The instruction is with being included in the network of the DNS service performed in equipment 2
Location.Therefore, when registering equipment 2, P-CSCF entities are stored in the network address of the DNS service performed in equipment 2.This causes P-
CSCF 5 can be to DNS query of the suitable registered forwarding of IMS equipment 2 for the domain associated with subscriber.
Alternatively, equipment 2 can use the IP address for being related to IP access networks 4.In this case, the DNS of equipment 2 is looked into
Inquiry will not pass through safe IMS connections.
The domain that equipment 2 is designated as official should be the domain of (being possessed) associated with the user of the equipment 2.The domain name in the domain
User Part that can be including one of the subscriber IMS public user identity (IMPU) in the implicitly registered set (IRS) of equipment 2 and domain
Part.For subscriber sip：John.smith@my-company.nl, the domain of DNS service is arranged in this example
john.smith@my-company.nl.Form of the public user identity symbol with domain of DNS service.Identify in this example with
Lower address element.Domain field " my-company.nl " causes by with forwarding SIP service to ask analogous side to IMS network
Formula, the IMS network forwarding DNS service request of service is provided to the user for domain my-company.nl.Field
" john.smith ", and please for the IMS network forwarding DNS service that service is provided to the user for domain my-company.nl
The domain field (in other words, complete domain john.smith@my-company.n1) asked, is used to identify and request DNS service
The subdomain that user is associated., can be to subdomain forwarding DNS service request using the DNS contact addresses being stored in HSS 8.Can
By the HSS Final 8, system implements the rule.
