For ease of the present invention there being further understanding, be described based on the specific implementation that realizes short message, Multimedia Message and instant messaging in the IP access network provided by the invention below in conjunction with accompanying drawing.

First kind of specific embodiments

In this embodiment, initiate message by the UE that inserts based on IP and transmit, and successfully received described message by the other side's the SM-SC of short message service center.

In this embodiment, the difference of the processing of adopting according to IP message gateway place specifically comprises two kinds of implementations that can adopt:

1, a kind ofly send response message to UE according to the message report of receiving for the IP message gateway is set to have only after receiving from the message report of SM-SC, this moment corresponding implementation procedure as shown in Figure 2;

2, in a single day another kind receives the reception of just confirming this message from the message of UE at once for the IP message gateway is set to it, and at this moment, corresponding implementation procedure as shown in Figure 3.

At first described first kind of implementation described below, as shown in Figure 2, specifically comprises following treatment step in conjunction with Fig. 2:

Step 11: IP-based UE (being called for short UE afterwards) uses general SIP or IMS registration process, and SIP or the heavy registration process of IMS be registered on the IP message gateway, realizes the registration operation of UE on the IP message gateway;

Step 12:UE uses SIP method (SIP Method) to send message to S-CSCF, and promptly UE sends message based on Session Initiation Protocol to S-CSCF, such as, can send MESSAGE message in the Session Initiation Protocol to S-CSCF;

Step 13:S-CSCF determines that according to filtering rule these message needs send to SMSIP messaging service functional entity, so the message of receiving at first is transmitted to the IP message gateway that is equivalent to an IMS AS, so that described forwards is arrived destination entity by this IP message gateway;

Step 14:IP information gateway is after receiving this message, then can carry out service authorization to the message of receiving according to the CAMEL-Subscription-Information that from HLR/HSS, obtains in the registration process, and when the service authorization success, from receive message, extract the message content that carries, and send after constructing corresponding SMSIP message, the MAP signaling that promptly can construct standard sends to SM-SC with message content through SMS-IWMSC;

In this step, the address of SM-SC is from the sip message head, as R-URI{Request-URI wherein, request URI (URI Universal resource identifier, unified resource identifier) } in header field or the sip message body;

If service authorization failure, the IP message gateway then can return a failure that contains error message to UE and reply, if promptly do not pass through authorization check, then in this step, the IP message gateway will stop receiving the processing of message, and the response message of returning a SIP MESSAGE message can indicate the UE reason of makeing mistakes for UE, described response message, so that reference is provided when carrying out subsequent treatment for UE.

After step 15:SMS-IWMSC receives the message that the IP message gateway sends, with this SMS forwards to SM-SC;

After step 16:SM-SC receives described message, then send the message transmission and report to SMS-IWMSC, write down SM-SC during message transmits and reports and whether successfully received described message;

Step 17:SMS-IWMSC continues to send it to described IP message gateway, i.e. IP-Message-GW after receiving that described message transmits report;

Step 18:IP information gateway transmits the result of report according to the message of receiving, constructs corresponding SIP response message and returns to UE;

Hypothesis SM-SC has received short message among Fig. 1, and it is success that the message of therefore returning transmits report, so the IP message gateway returns 200OK message and confirms that to UE the message that sends is successfully received;

It is other results outside the success that the message of receiving when the IP message gateway discovery transmits report, then construct the response message of corresponding SIP MESSAGE message according to this result, wherein information indication UE is the result that transmits of message this time, so that reference is provided when carrying out subsequent treatment for UE;

After step 19:S-CSCF receives described 200OK message, continue to be transmitted to UE, so far, once the transmission of messages processing procedure of being initiated by IP-based UE at SMSIP messaging service functional entity is finished dealing with, and promptly utilizes the terminal that the present invention is based on IP can realize corresponding SMSIP business in network.

Afterwards, in conjunction with Fig. 3 the processing of above-mentioned second kind of situation is described again, specifically comprises:

Step 21: IP-based UE (being called for short UE afterwards) uses general SIP/IMS registration process registration or heavily is registered on the IP message gateway;

Step 22:UE uses the SIP method, promptly adopts the message based on SIP to send information to S-CSCF, for example, can use SIP MESSAGE message;

After step 23:S-CSCF receives described message, give the IP message gateway that is equivalent to an IMS AS with the forwards of receiving according to filtering rule;

Step 24:IP information gateway is received after the described message, then the message of receiving is carried out service authorization according to the CAMEL-Subscription-Information that from HLR/HSS, obtains in the registration process, and after the service authorization success, then directly return 202Accept (202 accept) message to UE and give UE by S-CSCF, show that the message that UE sends is received by the IP message gateway, but, in this processing procedure, after UE receives described acknowledge message (being response message), do not represent this message successfully to be received, and only represent that corresponding message is received by the IP message gateway by SM-SC;

If the IP message gateway is at the service authorization failure that receives message, then it can return a failure response message that contains error message to UE by S-CSCF; Promptly in this step, if the message of receiving is not passed through authorization check, then the IP message gateway will stop receiving the processing of message, and return a response message that is used to represent the unsanctioned SIP MESSAGE of authorization check message and give UE, the indication UE reason of makeing mistakes in described response message, reference when carrying out subsequent treatment for UE.

After step 25:S-CSCF receives the message that the IP message gateway returns, then transmit described message and give UE, as with 202Accept (acceptances) forwards to UE.

Step 26: follow step 23, the IP message gateway is after receiving the message that S-CSCF sends, extract the content of carrying in the message, structure need send to the SMSIP message of corresponding entity, for example, the MAP signaling that can construct standard sends to SM-SC (the business function entity that promptly is used for treatment S MSIP message) with described content through SMS-IWMSC, and the address of wherein said SM-SC is from sip message head (as the R-URI header field) or the sip message body;

After step 27:SMS-IWMSC receives described message, forward the message to described SM-SC, thereby the message that makes UE send can be received by the SMSIP messaging service functional entity in the network exactly, to realize corresponding SMSIP business;

After step 28:SM-SC receives described message, send corresponding message to SMS-IWMSC and transmit report, write down the information whether SM-SC has successfully received described message in the described message report;

Step 29:SMS-IWMSC transmits report with the message of receiving and sends to the IP message gateway;

Described message can be transmitted to the IP message gateway via SMS-IWMSC, also can send the IP message gateway to via more intermediate entities;

After step 29, the message transmission report that the IP message gateway discovery is received is other results outside the success, and it can notify UE, perhaps also can not notify UE; Equally, successfully receive the information that UE sends, then can return corresponding acknowledge message, also can not return corresponding acknowledge message to UE if the message that the IP message gateway is received transmits report expression SM-SC.

Second kind of specific embodiments

In this embodiment, be a short message that sends from short message service among the GSM as called reception with IP-based UE, and be received as successfully that example is described.

The concrete handling process of this embodiment may further comprise the steps as shown in Figure 4:

Step 31: use general SIP/IMS registration process or heavy registration process to be registered to the IP message gateway as called IP-based UE;

Step 32:SM-SC determines and need then give SMS-GMSC with described forwards to the short message of IP-based UE transmission;

After step 33:SMS-GMSC receives described short message, then can send a request message, receive the routing iinformation of message with inquiry and acquisition to HSS/HLR;

Because described UE has finished corresponding IMS registration, therefore, HSS will return the address of IP message gateway to SMS-GMSC after receiving described request message;

Step 34:SMS-GMSC is according to the address information of the IP message gateway that obtains from HSS, send this short message to the IP message gateway as sending SMS message to MSC or SGSN, wherein, carry MSISDN (mobile station ISDN number) number information as called described UE;

Step 35:IP information gateway, be after IP-Message-GW receives the described short message that SMS-GMSC sends, the TEL-URI (resource of phone number format is unified identifier) of called UE is inserted among the R-URI of sip message, then, based on SIP corresponding message content is sent to S-CSCF, for example, can use SIP MESSAGE to send described message content;

After step 36:S-CSCF receives described message, continue to transmit this message and give described UE;

Step 37: described UE receives after this message, will construct the response message of returning according to result, for example, when UE has successfully received this message, then returns the 200OK response message by S-CSCF to the IP message gateway;

After step 38:S-CSCF receives described 200OK response message, continue to transmit described 200OK response message and give the IP message gateway;

Step 39:IP information gateway transmits report according to the response message structure that the UE that receives returns to the message that SMS-GMSC returns, described message transmits whether expression UE successfully receives described message in the report, has successfully received the message transmission report of described message here just according to the expression UE of 200OK response message structure;

After step 310:SMS-GMSC receives that described message transmits report, send this message and transmit report condition to HSS/HLR;

Step 311: simultaneously, after SMS-GMSC receives that described message transmits report, also continue to transmit report to the SM-SC return messages.

What describe in handling process shown in Figure 3 is to use SIP MESSAGE to describe as example.In actual applications, IP-based terminal is when using short message service, because the limited length of short message, so use SIP MESSAGE method to transmit just enough.

Need to prove that the present invention does not get rid of use MSRP (message session trunk protocol) and waits other to transmit the situation of information based on the agreement of SIP in the specific implementation process.That is to say, in the above-described embodiments, all be to be the explanation that example is carried out with concrete sip message, and the present invention also can realize the corresponding processing procedure that transmits by other similar protocol messages according to actual conditions in actual applications; Be that the sip message of describing among the present invention also can use other similarly to replace based on the message of Session Initiation Protocol.

The third specific embodiments

When the 3GPP of IP-based access technology support messaging service is the MMS business, can use treatment mechanism provided by the invention equally, when promptly IP-based UE initiates the transmission of MMS message.Specifically be to be example in this embodiment to adopt the MSRP agreement, describe IP-based terminal and use the realization flow of MMS business, wherein, the transport process of corresponding M MS message can adopt the similar processing of the forwarding short message of the SMS described in the second kind of specific embodiments in front similarly.

The concrete handling process of this embodiment comprises following treatment step as shown in Figure 5:

Step 41: IP-based UE (UE is called for short in the back) uses general SIP/IMS registration process to be registered on the IP message gateway;

Step 42:UE uses SIP method (promptly based on Session Initiation Protocol) to initiate the message transport process, sends INVITE (invitation) message and gives the IMS network;

In this step, specifically can use the MSRP agreement to transmit corresponding Multimedia Message, in actual applications, also can adopt other to transmit corresponding message as modes such as SIP MESSAGE;

Step 43, step 44:S-CSCF carry out professional control, determine that this message need send to SMSIP messaging service functional entity, then this INVITE are transmitted to an IMS AS (IMS application server), i.e. IP message gateway;

After step 45:IP information gateway is received described INVITE, according to the CAMEL-Subscription-Information that from HLR/HSS, obtains in the registration process message of receiving is carried out the service authorization operation, and after the service authorization at this message passes through, by the transport process of IP message gateway initiation MMS message, thereby connect with MMS Relay (relaying)/Server (server);

Wherein, described MMS message transport process comprises the professional establishment of connection of MMS, the transmission of MMS message and other relevant treatment, comprise and receive the message that UE sends through S-CSCF, and be transmitted to MMS Relay/Server, and the information that receives the message sink situation that MMS Relay/Server sends, and return corresponding acknowledge message to described UE, or the like; So, in the transport process of the MMS message that follow-up step 46 to the IP message gateway that provides between the step 413 is initiated, if any mistake takes place in MMS message transport process, then may cause the IP message gateway to send corresponding failure and reply to UE, be the failure response message such as what may be in step 46 and step 412 return to UE;

In this step, if the IP message gateway at the service authorization operation failure of corresponding message, then the IP message gateway can return a failure that contains error message to UE and replys, and promptly is the failure response message to what UE returned this moment in step 46 and step 47;

Step 46: with service authorization successfully is example, and at this moment, the IP message gateway will return 200OK message and give S-CSCF;

If do not pass through authorization check in the step 45, then the IP message gateway stops receiving the processing of message, and in this step 46, will return the response message of corresponding sip message to UE, the described response message indication UE reason of makeing mistakes, reference when carrying out subsequent treatment for UE.

After step 47:S-CSCF receives described message, continue to transmit 200OK message and give UE;

Step 48, step 49:UE confirm the successful foundation of this SIP session;

Step 410, step 411: after the SIP session was set up successfully, UE just can use SEND (transmission) message of MSRP agreement to begin to carry out the message transfer operation, and promptly UE will need the message process S-CSCF that sends to be transmitted to the IP message gateway;

Step 412, step 413: when the IP message gateway confirms that MMS Relay/Server finishes the reception of message, then need to return 200OK message and give UE;

In this step, the transmission action need of corresponding message depends on the successful foundation of the connection between IP message gateway and the MMS server, and the IP message gateway can receive message by the MSRP mode;

If before step 412, the IP message gateway occurs any unusual in MMS message transport process, the response message that then can construct corresponding M SRP in step 412 sends to described UE, unusual error reason appears in described response message carrying, UE indicates according to the error reason in the described response message, carry out corresponding process operations, described processing operation specifically comprises: carry out and retransmit, heavily consult or stop message transmission etc. at once.

Step 414 is to step 417: described UE uses BYE (leaving) message to discharge corresponding SIP session finishing after message sends, after the IP message gateway is received described BYE message, discharge and UE between the SIP session, and return 200OK message to UE;

The message that step 418:MMS server (or MMS relaying) is sent the UE that receives sends to the recipient, promptly transmits MMS message and gives recipient's subscriber equipment;

In actual application, this step can be carried out in step 417 back as required, also can conveniently begin to carry out after step 45 executes.

Step 419:MMS server (or MMS relaying) is according to the transmission result of MMS message, can send message to the IP message gateway by SMS-IWMSC and transmit report, specifically can send corresponding message and transmit report, promptly at first described message be transmitted report and send to SMS-IWMSC by short message service;

Step 420:SMS-IWMSC then inquires about the current routing iinformation of UE to HLR/HSS after receiving that described message transmits report, and obtains the address information of corresponding IP message gateway;

Step 421:SMS-IWMSC is according to the routing iinformation that obtains, and promptly the address information of IP message gateway transmits report with described message and sends to the IP message gateway;

Step 422:IP information gateway transmits the report executing subsequent processes according to the message of receiving;

If after the step 421, the message transmission report that the IP message gateway discovery is received is other results outside the success, can notify or not notify UE, if notice can be provided with as required and adopt corresponding informing mechanism; In addition, the IP message gateway also may be according to the indication in the message transmission report, and initiation and UE set up the process of SIP session, and request UE resends message.Equally, transmit successful message for the expression message of receiving and transmit report, also can notify UE or not notify UE.

The 4th kind of specific embodiments

As called reception during from the MMS message of GSM/GPRS network, corresponding specific implementation flow process may further comprise the steps as shown in Figure 6 for IP-based UE:

Step 51: IP-based UE (UE is called for short in the back) uses general SIP/IMS registration process to be registered on the IP message gateway;

Step 52 to step 55:MMS server (or MMS relaying) receives that the purpose user is based on the MMS message of the UE of IP, then at first use the mode of short message to send the notice of receiving MMS message to the IP message gateway, comprising the information of this MMS message of sign, such as a URL address of MMS ID (MMS sign) or indication MMS message preservation position;

In this processing procedure, can comprise a service authorization process, be that the IP message gateway is carried out service authorization according to the CAMEL-Subscription-Information that obtains in the registration process to the MMS message of receiving from HLR/HSS, after authorizing successfully, continue to carry out described step 56, if authorization failure, the IP message gateway returns a failure response message that contains error message to the messaging service related functional entities;

Step 56 to step 59:IP information gateway sends message informing UE according to the method for handling short message;

Promptly in this process, MMS message is sent to described UE with the form of SIP Message by S-CSCF, after UE correctly receives described message, will return 200OK message to the IP message gateway;

After carrying out described step 56 or step 59, receive the result of message according to UE, can handle to MMS server at the transmission of short message and send corresponding message transmission report, describe in this processing procedure front of considering short message, so repeat no more;

Step 510: after described UE receives the MMS message of sending in the mode of Session Initiation Protocol, initiate the message transport process, promptly at first send INVITE, wherein carry the information of the MMS message that is used to indicate needs reception to the IMS network based on SIP;

Since need transmit Multimedia Message at this, thus SIP MESSAGE do not used, and be to use the MSRP agreement, and in the practical application, various methods based on SIP (SIP method) and other agreements that realizes similar functions all can adopt.

Step 511, step 512: described INVITE at first sends to S-CSCF, and carries out professional control by S-CSCF at described message, and this INVITE is transmitted to an IMS AS, i.e. IP message gateway, and the IP message gateway is received INVITE;

Step 513:IP information gateway is received the transport process of initiating MMS message behind the described INVITE, connects with MMS Relay/Server, so that obtain corresponding M MS message from MMS Relay/Server;

Described MMS message transport process comprises: the professional establishment of connection of MMS, the transmission of MMS message and other relevant treatment, therefore, in step 514 to the processing procedure of step 519, if any mistake takes place in the MMS message transport process, all will cause the IP message gateway to send corresponding failure replys to UE, such as return the failure response message in step 514, and, if make mistakes, then step 518 may be a SIP BYE message that directly discharges this SIP session, perhaps, may be the heavily negotiations process of a SIP session; When confirming mistake not occur, then continue execution in step 514;

Step 514 to step 517:IP information gateway returns 200OK message and gives S-CSCF, after S-CSCF receives described message, continue to transmit this 200OK message and give UE, after UE receives described message, then send ACK (affirmation) message to the IP message gateway by S-CSCF, to confirm the successful foundation of this SIP session, can receive corresponding Multimedia Message;

Step 518 to the Multimedia Message that step 521:IP information gateway uses SEND (transmission) message of MSRP agreement to begin to obtain from MMS Relay/Server sends UE to, and corresponding message specifically is to be transmitted to UE through S-CSCF;

Successful connection between IP message gateway and MMS server is set up, and, receive by the MSRP mode and not occur any problem in the message process, then UE need return 200OK message to the IP message gateway when message sink is intact;

Step 522: after complete described step 521, between IP message gateway and short message service center or MMS server, send message and transmit report;

Be the result of IP message gateway, in the message transport process, also may relate to the transport process that message transmits report, if relate to the transport process that this message transmits report, then execution in step 522 and subsequent processing steps according to UE reception message;

Step 523 to step 526:IP information gateway is finished after message sends, use BYE message to discharge SIP session between itself and the UE, and UE returns 200OK message to the IP message gateway after described SIP session discharges successfully, and the message that the release conversation procedure relates to remains by S-CSCF to be transmitted.
