Description

A kind of messaging service implementation method based on the IP network IP multimedia subsystem, IMS

Technical field

The present invention relates to the network communications technology field, be specifically related to a kind of messaging service implementation method based on the IP network IP multimedia subsystem, IMS.

Background technology

Development along with broadband network, mobile communication will not only be confined to traditional Speech Communication, multimedia service in conjunction with multiple medium types such as audio frequency, video, picture and texts will be carried out gradually, by browse with presence (presenting business), short message, WEB (webpage), the combining of data services such as locating information, PUSH (pushing professional), file-sharing, can satisfy mobile subscriber's multiple demand.

Under the promotion of multiple application, normal structure such as 3GPP and 3GPP2 has successively been released the framework based on IMS (IP multimedia subsystem, IMS of IP), its objective is: use a kind of structure of standardized opening to realize diversified multimedia application in the mobile network, the mobile subscriber is more to be selected and abundanter impression thereby offer.

In 3GPP Release 5 (R5) stage, introduced IMS domain, be called for short IMS, be superimposed upon on the packet field network, by CSCF (CSCF), MGCF (MGCF), MRF (media resource function) and HSS functional entitys such as (home signature user servers) are formed, wherein CSCF can be divided into S-CSCF (serving CSCF) again, three logic entities of P-CSCF (proxy CSCF) and I-CSCF (inquiry CSCF), S-CSCF is the service switching center of IMS, carry out session control, peace preservation association's speech phase, be in charge of user profile, produce charge information etc.P-CSCF is the access point of terminal user access to IMS, finishes user's registration, is responsible for QoS control and safety management etc., and I-CSCF is responsible for the intercommunication between the IMS territory, and network topology and configuration are externally hidden in the distribution of management S-CSCF, produce metering data etc.The MGCF control gateway realizes the intercommunication of IMS network and other network, and MRF provides media resource, as the folding and unfolding sound, and encoding and decoding and multimedia conferencing bridge.HSS is a customer data base, storage IMS user's subscription data and configuration information etc.

Because it is irrelevant that the structure of IMS network has been accomplished with the bottom bearer network, therefore the IMS network of 3GPP definition also can be applied on other packet networks outside the packet field network of 3GPP definition, such as the packet network that defines among the 3GPP2, wlan network and NGN network etc., realized and the independence of terminal type and and the independence of access network type.Therefore, can not limit IMS only is applied in relevant network of 3GPP and the application, the access network of other types and the business of bearer network and application also can realize with the IMS framework, like this, IMS is the essential step that system evolution is provided to All IP Network business for the multimedia application in future provides a general business to enable platform.

At present, 3GPP has defined the messaging service of two classes based on the IMS framework: professional and conversation-based message (the Session Based Messaging) business of immediate message (ImmediateMessaging).

Below in conjunction with accompanying drawing the implementation method of messaging service immediately is elaborated.

Under the situation that called subscriber UE#2 has registered in the IMS territory, the implementation procedure that sends immediate message to UE#2 based on the calling subscriber UE#1 of IMS framework as shown in Figure 1.

Among Fig. 1, the message of step 1, UE#1 editing multimedia content, and need this message is sent to UE#2.

Send MESSAGE (message) request to step 2, UE#1 to the P-CSCF#1 corresponding, comprise its editor's content of multimedia in the message body of this MESSAGE request with it.

Transmit this MESSAGE request to step 3, P-CSCF#1 to the S-CSCF#1 of the current registration of UE#1.

To step 4, according to the carrier policy that disposes among the S-CSCF#1, S-CSCF#1 checks message-length and type in this MESSAGE request, in addition, S-CSCF#1 may trigger the service logic that is complementary with this MESSAGE request, as MESSAGE being routed to an AS (Application Server application server), to carry out follow-up processing.

Transmit this MESSAGE request to step 5, S-CSC#1 to I-CSCF#2.

Carry out routing inquiry to step 6, I-CSCF#2, promptly ask the address information of the S-CSCF of UE#2 to HSS.The address information of the S-CSCF of UE#2 is the address information of S-CSCF#2.

Transmit the MESSAGE request to step 7, I-CSCF#2 to S-CSCF#2.

To step 8, according to the carrier policy that disposes among the S-CSCF#2, S-CSCF#2 checks message-length and type in the MESSAGE request, in addition, S-CSCF#2 may trigger the service logic that is complementary with the MESSAGE request, as MESSAGE being routed to an AS to carry out follow-up processing.As when the current business that an activation is arranged of UE#2, as the business etc. that shields certain class message causes this message not issue, and AS then can respond to the S-CSCF#2 return error.

Transmit the MESSAGE request to step 9, S-CSCF#2 to the current P-CSCF#2 of UE#2.

After receiving MESSAGE request to step 10, P-CSCF#2, transmit this MESSAGE request to UE#2, UE#2 shows content of multimedia to the terminal use.

From step 11 to step 16, UE#2 is to UE#1 return messages acceptance response message.

Registration is not but UE#2 has contracted under the situation of " unregistered state business " in the IMS territory as yet at UE#2, and the implementation procedure that sends immediate message to called subscriber UE#2 based on the calling subscriber UE#1 of IMS framework as shown in Figure 2.

Among Fig. 2, the message of step 1, UE#1 editing multimedia content, and need this message is sent to UE#2.

Send the MESSAGE request to step 2, UE#1 to the P-CSCF#1 corresponding, comprise the content of multimedia that UE#1 edits in this MESSAGE request message body with it.

Transmit the MESSAGE request to step 3, P-CSCF#1 to the S-CSCF#1 of the current registration of UE#1.

Arrive step 4, S-CSCF#1 according to the carrier policy that disposes, message-length and type in the MESSAGE request are checked, in addition, S-CSCF#1 may trigger the service logic that is complementary with the MESSAGE request, as MESSAGE being routed to an AS to carry out follow-up processing.

Transmit the MESSAGE request to step 5, S-CSCF#1 to I-CSCF#2.

Carry out routing inquiry to step 6, I-CSCF#2, promptly ask the address information of the S-CSCF of UE#2 correspondence to HSS, the address information of the S-CSCF of UE#2 is the address information of S-CSCF#2.

At this moment, because UE#2 is not registered in the IMS territory, for the UE#2 that does not have registration, HSS checks whether it has contracted " unregistered state business ", if UE#2 has contracted " unregistered state business ", HSS can specify some S-CSCF as S-CSCF#2, returns the address information of this S-CSCF#2 to I-CSCF#2, or HSS returns desired S-CSCF ability information to I-CSCF#2, selects suitable S-CSCF as S-CSCF#2 voluntarily for I-CSCF#2.

Then, I-CSCF#2 transmits the MESSAGE request to S-CSCF#2, S-CSCF#2 receives the MESSAGE request, and after from HSS, downloading the relevant data of UE#2 according to the user ID of UE#2, " the unregistered state business " of contracting according to the user triggers the professional control logic of being mated again, transmit the MESSAGE request to certain AS, carry out follow-up flow processing by AS.If user's not signatory " unregistered state business ", then HSS returns the routing inquiry failure response.

Transmit the MESSAGE request to step 7, I-CSCF#2 to S-CSCF#2.

To step 8, according to the carrier policy that disposes among the S-CSCF#2, S-CSCF#2 checks message-length and type in the MESSAGE request, and can further check current whether the business that causes the activation that this message can not issue is arranged, as shield the activation of service of certain class message.In addition, S-CSCF#2 can trigger the service logic that is complementary with the MESSAGE request, as MESSAGE being routed to an AS to carry out follow-up processing.Finally, this MESSAGE is sent to UE#2.

From step 9 to step 12, UE#2 is to UE#1 return messages acceptance response message.

At present 3GPP has proposed based on the network architecture of the messaging service of IMS and traditional short message service interworking as shown in Figure 3.

Embodiment

Core of the present invention is: determine called subscriber's network domains based on the Calling Side of IP network IP multimedia subsystem, IMS according to the predetermined information that carries in calling subscriber's messaging service, described Calling Side is realized messaging service according to described called subscriber's network domains.

Based on core concept of the present invention technical scheme provided by the invention is further described below.

Because the called subscriber may be the user in the IMS network domains, also may be the user in the CS/PS network domains, so when the initiation of the calling subscriber UE#1 in the IMS network domains was professional based on the immediate message of IMS, the network of UE#1 side need be judged the network domains of called subscriber UE#2.

Judge that the CSI called subscriber identification that called subscriber's network domains is carried in can the immediate message business by UE#1 realizes, message as the UE#1 editing multimedia content, and need this message is sent to UE#2, UE#1 sends MESSAGE (message) request to P-CSCF#1, the content of multimedia that includes its editor in the message body of this MESSAGE request, P-CSCF#1 transmits this MESSAGE request to the S-CSCF#1 of the current registration of UE#1, and S-CSCF#1 receives and judge the form of the CSI called subscriber identification of carrying in the MESSAGE request.

When S-CSCF#1 determines that the CSI called subscriber identification of carrying in the MESSAGE request is the CSI called subscriber identification of SIP URI form, illustrate that then the called subscriber may be the user in the IMS network domains, S-CSCF#1 can according in the IMS network domains immediately the implementation procedure of messaging service proceed to handle, be the I-CSCF#2 that S-CSCF#1 transfers to the MESSAGE request called subscriber's side correspondence, inquire about routing iinformation by I-CSCF#2 at HSS to the called subscriber, and when HSS found that the called subscriber has been registered in the network of IMS territory, I-CSCF#2 continued to realize messaging service according to the description flow process to Fig. 1 in the background technology.When I-CSCF#2 is finding called subscriber's not registration but when having contracted " unregistered state business ", I-CSCF#2 continues to realize messaging service according to the description flow process to Fig. 2 in the background technology in the IMS territory as yet to called subscriber's HSS inquiry routing iinformation and HSS.

When S-CSCF#1 determined that the CSI called subscriber identification of carrying in the MESSAGE request is the CSI called subscriber identification of TEL URI form, S-CSCF#1 need continue to judge whether the form of the CSI called subscriber identification of carrying in this MESSAGE request can be converted to SIP URI form.The process whether CSI called subscriber identification of judging TEL URI form can be converted to the CSI called subscriber identification of SIP URI form can realize by the information interactive process of S-CSCF#1 and E.164 Number server, the CSI called subscriber identification of TELURI form is converted to the CSI called subscriber identification of SIP URI form as S-CSCF#1 request E.164 Number server.

When E.164 Number server can be successfully converts the CSI called subscriber identification of TEL URI form the CSI called subscriber identification of SIPURI form to, S-CSCF#1 can proceed to handle according to the implementation procedure of the immediate message business of IMS network domains, be the I-CSCF#2 that S-CSCF#1 transfers to the MESSAGE request called subscriber's side correspondence, when called subscriber's HSS inquiry routing iinformation and HSS find that the called subscriber has been registered in the network of IMS territory, I-CSCF#2 continues to continue to realize messaging service according to the description flow process to Fig. 1 in the background technology by I-CSCF#2.When I-CSCF#2 is finding called subscriber's not registration but when having contracted " unregistered state business ", I-CSCF#2 continues to realize messaging service according to the description flow process to Fig. 2 in the background technology in the IMS territory as yet to called subscriber's HSS inquiry routing iinformation and HSS.

When S-CSCF#1 determines that according to the result with the E.164 Number server information interaction CSI called subscriber identification of TEL URI form can not be converted to the CSI called subscriber identification of SIP URI form, S-CSCF#1 is according to the service logic that is complementary with this MESSAGE request, this MESSAGE request is routed to an AS, as IP-MESSAGE-GW, carry out the subsequent message processing procedure by IP-MESSAGE-GW.

Above-mentioned is to judge that with the S-CSCF#1 of calling subscriber's correspondence the network domains of called subscriber UE#2 is that example is described, the present invention also can be judged called subscriber's network domains by the IP-MESSAGE-GW of calling subscriber's correspondence, IP-MESSAGE-GW judges that the process of called subscriber's network domains and S-CSCF#1 judge that the process of called subscriber's network domains is basic identical, and this implementation procedure can embody from following description to accompanying drawing 7.

IP-MESSAGE-GW carries out the subsequent message processing procedure and can be specially: IP-MESSAGE-GW parses this MESSAGE message content, and it is assembled into the MAP signaling of standard, send this MAP signaling to SMS-IWMSC/SM-SC then, wherein, source address in this MAP signaling should be the MSISDN of UE#1, and destination address is the address information of the SMS-IWMSC/SM-SC of UE#1.

In addition, IP-MESSAGE-GW can also convert the identification information of the TEL URI form of called subscriber's UE#2 to the E.164 identification information of form, and with this E.164 the identification information of form fill in the message body of MAP signaling as the part of content of short message.

If IP-MESSAGE-GW can not be assembled into this MESSAGE message content the MAP signaling of standard, as carrying the unsupported information unit of MAP signaling in the MESSAGE message, method then of the present invention finishes.

The address information of the SMS-IWMSC/SM-SC of above-mentioned UE#1 can be to be parsed from the MESSAGE request that UE#1 sends by IP-MESSAGE-GW, also can be when the identification information of UE#1 and the address information of self being registered to HSS by IP-MESSAGE-GW, obtaining in the UE#1 user data of downloading from HSS, can also be by having stored the process acquisition of carrying out information interaction with the storage entity of UE#1 relevant information with other by IP-MESSAGE-GW.

The MSISDN of above-mentioned UE#1 is by IP-MESSAGE-GW that the identification information of the SIP URI form of UE#1 is converted.IP-MESSAGE-GW can be when being registered to HSS with the identification information of UE#1 and the address information of self, the corresponding relation of the identification information of the identification information of the SIP URI form of download UE#1 and MSISDN form from HSS, thereby convert the identification information of the SIP URI form of UE#1 among the MESSAGE identification information of MSISDN form to, and with the MSISDN of the UE#1 that changes out source address information as the MAP signaling by this corresponding relation.

Implementation method below in conjunction with 7 pairs in accompanying drawing 6, the accompanying drawing messaging service based on the IP network IP multimedia subsystem, IMS provided by the invention is elaborated.

Among Fig. 6, be registered among the S-CSCF according to the IMS register flow path at step 6-1, calling subscriber UE.In the register flow path of IMS, can relate to the message of transmitting between functional entitys such as I-CSCF and P-CSCF and a lot of S-CSCF and the HSS,, not list one by one here for for purpose of brevity.

Send MESSAGE request based on SIP (initial session protocol) MESSAGE mode to S-CSCF to step 6-2, calling subscriber.

Analysis and judgement is carried out in the CSI called subscriber identification of carrying in step 6-3, the S-CSCF MESSAGE request message to its reception.

When S-CSCF determines that the CSI called subscriber identification of carrying in the MESSAGE request is the CSI called subscriber identification of SIP URI form, illustrate that then the called subscriber may be the user in the IMS network domains, S-CSCF can proceed to handle according to the implementation procedure of the immediate message business in IMS territory, be the I-CSCF#2 that S-CSCF transfers to the MESSAGE request called subscriber's side correspondence, I-CSCF#2 inquires about routing iinformation at the HSS to the called subscriber, and when HSS found that the called subscriber has been registered in the network of IMS territory, I-CSCF#2 continued to realize messaging service according to the description flow process to Fig. 1 in the background technology.When I-CSCF#2 is finding called subscriber's not registration but when having contracted " unregistered state business ", I-CSCF#2 continues to realize messaging service according to the description flow process to Fig. 2 in the background technology in the IMS territory as yet to called subscriber's HSS inquiry routing iinformation and HSS.

When the CSI called subscriber identification that S-CSCF carries in determining the MESSAGE request message is the CSI called subscriber identification of TEL URI form, S-CSCF visits E.164 Number server, carry out information interaction with E.164 Number server, when S-CSCF determines that according to the information interaction result with E.164 Number server the CSI called subscriber identification of TEL URI form can be converted to the CSI called subscriber identification of SIP URI form, illustrate that the called subscriber is the user in the IMS network domains, S-CSCF can proceed to handle according to the implementation procedure of IMS territory immediate message business, be the I-CSCF#2 that S-CSCF transfers to the MESSAGE request called subscriber's correspondence, inquire about routing iinformation by I-CSCF#2 at HSS to the called subscriber, and when HSS finds that the called subscriber has been registered in the network of IMS territory, continue to realize messaging service according to the description flow process to Fig. 1 in the background technology.When I-CSCF#2 is finding called subscriber's not registration but when having contracted " unregistered state business ", I-CSCF#2 continues to realize messaging service according to the description flow process to Fig. 2 in the background technology in the IMS territory as yet to called subscriber's HSS inquiry routing iinformation and HSS.
