Description

A kind of method that transmits message based on the message transmission protocol of Internet protocol of using
Technical field
The messaging service that the present invention relates to Internet protocol (IP) network and mobile communications network is realized, particularly a kind of method of using IP-based message transmission protocol to transmit message.
Background technology
Continuous appearance and development along with various IP access technologies, for third generation partner program (3GPP), bearing bed will be not only existing mobile communications network, as general packet radio service (GPRS) network or mobile communication digital cell mobile communication systems (GSM), also can be other access networks based on packet switching, such as: wireless lan (wlan) and code division multiple access (CDMA) 2000 networks or the like are commonly referred to as the IP access network here.Various application in mobile communications network, also should be able on this multiple IP access network, transmit, use for the IP user, for example short message service (comprising SMS and EMS) and multimedia messaging service, MMS (MMS) are exactly a kind of business that is widely used on mobile communications network, need to consider how it to be implemented on the IP access network and and GPRS network intercommunication.
Fig. 1 comprises: the mobile switching centre (GMSC/SMS-IWMSC) of the Short Message Entity in the network (SME), Short Message Service Center (SM-SC), gateway MSC/short message-IWF, Charging Gateway Functionality/charging data function (CGF/CDF) and home signature user server/attaching position register (HSS/HLR) for prior art inserts the network architecture figure that supports short message service by IP terminal equipment (UE); IP message gateway (IP-Message-GW) in the IP access network, Online Charging System (OCS) and IP UE.
Wherein, IP-Message-GW is used to provide the protocol interconnection between IP UE and the mobile communications network, thereby supports the transmission of short message and Multimedia Message.Use the circuit switching signaling that is carried on the SS7 between IP-Message-GW and the GMSC/SMS-IWMSC, therefore for GMSC/SMS-IWMSC, mobile switching centre (MSC) or Serving GPRS Support Node (SGSN) that IP-Message-GW just is equivalent in the mobile communications network are the same, and how insert between MSC or SGSN and the GMSC/SMS-IWMSC, and then use SM-SC to realize that the transmission of short message and Multimedia Message is the implementation of short message and Multimedia Message in the existing mobile communications network by the circuit switching signaling.Interface between IP-Message-GW and the IP UE is an Interface R2, IP UE realizes short message service and multimedia messaging service, MMS by this interface, and IP UE is realizing that registration and authentication before short message service and the multimedia messaging service, MMS are the functions that IP-Message-GW provides.
SME, SM-SC and GMSC/SMS-IWMSC realize the functional entity that short message service and multimedia messaging service, MMS are used in the mobile communications network.SME provides the function of transmitting-receiving short message and Multimedia Message; SM-SC provides the function of storage short message and Multimedia Message; When terminal equipment (UE) received short message, GMSC inquired about routing iinformation by the R5 interface to HSS/HLR; SMS-IWMSC provides the authentication functions of the UE that sends SMS message.
HSS/HLR is used for preserving the UE data, in based on the IP message business, IP UE must register to IP-Message-GW in the time of will using the messaging service of IP-based message transmission protocol, IP-Message-GW with self address and the registration status notification of this IP UE and be kept among the HSS.As GMSC during to the routing iinformation of HSS/HLR inquiry IP UE, HSS returns to GMSC with the address of IP-Message-GW.
CGF/CDF user collects and handles the ticket information of the offline charging of UE and IP UE, sends to the charging center then and handles; OCS is used to collect the also ticket information of the online charging of process IP UE, sends to the charging center then and handles.
Realize that with the IP UE in the 3GPP TR 23.804v110 standard process of transmitting-receiving short message service is that example illustrates how IP UE receives and dispatches short message and Multimedia Message below.
The signaling process figure that Fig. 2 sends SMS message for prior art IP UE, its concrete steps are:
Step 200, IP UE use general registration process to be registered on the IP-Message-GW.
Step 201, IP UE send message to IP-Message-GW, and this message is used the IP address that carries content of short message and IP UE in IP-based message transmission protocol and this message.
Step 202, IP-Message-GW go out content of short message from this message extraction, and get access to the mobile user comprehensive service digital net number (MSISDN) of the IP address correspondence of IP UE at the log-on message of HSS/HLR according to IP UE, the message that structure carries the MSISDN of content of short message and IP UE sends to SMS-IWMSC, and this message is based on the circuit switching signaling.
Below transmission defines in TS23.040 based on the process details of the message of circuit switching signaling.
Step 203, SMS-IWMSC transmit this message based on the circuit switching signaling and arrive SM-SC.
The message based on the circuit switching signaling of sending step 204, the SM-SC that receives this circuit switching signaling transmits and reports to SMS-IWMSC.
This message based on the circuit switching signaling of transmitting step 205, SMS-IWMSC transmits and reports to IP-Message-GW.
Step 206, IP-Message-GW will be somebody's turn to do based on the message of circuit switching signaling and carry out protocol conversion, and structure uses the message of IP-based message transmission protocol to transmit report and sends to IP UE.
Fig. 3 is the signaling process figure that prior art IP UE receives short message, and its concrete steps are:
Step 300, purpose IP UE use general registration process to be registered on the IP-Message-GW.
Content of short message that step 301, SM-SC will receive from UE and short message information are carried at the message based on the circuit switching signaling, send to SMS-GMSC.
Step 302～303, SMS-GMSC send a request message to HSS/HLR and inquire about the routing iinformation of this message, this request message comprises that this SMS-GMSC of indication supports the indication of the messaging service of the IP-based message transmission protocol of use, and HSS/HLR returns the E.164 address of three E.164 address: MSC, the E.164 address of SGSN and the E.164 address of IP-Message-GW to SMS-GMSC.
Step 304, SMS-GMSC transmit this message according to the address that obtains, and supposition here selects the E.164 address of IP-Message-GW to transmit this message based on the circuit switching signaling.
Step 305, IP-Message-GW go out content of short message from this message extraction, MSISDN according to purpose IP UE gets access to pairing IP address from HSS/HLR, content of short message is carried in the message of using IP-based message transmission protocol sends to purpose IP UE.
After step 306, IP-Message-GW send the message of using IP-based message transmission protocol, transmit report for the SMS-GMSC return messages.
Step 307, SMS-GMSC transmit report condition for the HSS/HLR return messages.
Step 308, SMS-GMSC transmit report for the SM-SC return messages.
IP UE realizes that the process of transmitting-receiving multimedia messaging service, MMS is similar with Fig. 2 and Fig. 3 respectively, and the message body that the message of only using IP-based message transmission protocol to transmit is carried is the message content that extracts in the Multimedia Message.
Use the messaging service of IP-based message transmission protocol to also have a lot of flow processs to finish message in realizing and transmit, only described the process that the most basic initiation message transmits and receives message here, other processes please refer to 3GPP TR 23.804 standards.
From Fig. 2 and the described scheme of Fig. 3 as can be seen, when receiving and dispatching short message and Multimedia Message between IP UE and the mobile communications network, how just to have considered will from the mobile communications network pass through the circuit switching signaling or based on the message body of wireless application protocol (wap) carrying in IP-Message-GW how by protocol conversion, be converted to and use the message of IP-based message transmission protocol to send to IP UE, perhaps will from the message content that passes through IP carrying in the IP access network in IP-Message-GW how by protocol conversion, be converted to based on the circuit switching signaling or based on the message of WAP and send to mobile communications network.Like this, though can realize short message and Multimedia Message transmitting-receiving between IP UE and the mobile communications network, but in actual applications, adopt these two kinds of methods to realize that short message and Multimedia Message transmitting-receiving between IP UE and the mobile communications network are in-problem.
In actual applications, short message service and multimedia messaging service, MMS have developed a lot of application on its basis as the business that exists for a long time.When introducing the IP access network and after the IP access network is realized short message service and multimedia messaging service, MMS, IP-Message-GW is to the protocol conversion and the transmission of content of short message and multimedia information content, and there is a strong possibility can have influence on multiple application in short message service and the multimedia messaging service, MMS.Need utilize short message to trigger some application such as IP UE, but because IP-Message-GW is to based on the employing message communicating protocol encapsulation in the message of circuit switching signaling, short message information and content of short message as direct transfer applying unit (DTAP) encapsulation have carried out protocol conversion, be converted to the transportation protocol that transmits message in the IP access network, cause short message information in this message no longer to exist or need IP UE to reset triggering logic realizing original application, this changes too big for IP UE.
In the application of this external existing short message service and multimedia messaging service, MMS, as download business such as the tinkle of bells picture, be to need the user on UE, to import the specific character combination, send to the service provider by GMSC/SMS-IWMSC, the service provider triggers the applied logic that user's request is returned in corresponding configuration according to the input combination of UE, UE with its parsing and execution, wishes the application of downloading thereby obtain UE according to the rule that sets in advance after receiving this applied logic.But, because these short message service and multimedia messaging service, MMSs that all are based in the mobile communications network are expanded the application that obtains, in general, provide the service provider of these application to support mobile communications network, but might not support the IP access network, especially in the early stage of development of IP access network,, all be disadvantageous to user's the impression and the popularization of IP access network if the user has used IP UE to cause using the application of these short message services on the contrary.
In sum, how when using IP to transmit message, guarantee that short message and the information in the Multimedia Message in this message are not lost, make the IP UE that receives this message trigger corresponding being applied to according to the information that gets access to for a problem demanding prompt solution.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment and, the present invention is described in more detail with reference to accompanying drawing.
At present, the UE for using the existing mobile communication network short message service to use should support DTAP, and the network entity that DTAP is used for UE and mobile communications network carries out information interaction.For the employed IP UE of user, if wish to use the application of carrying out based on the short message service of existing mobile communications network, IP UE also wants to support DTAP so.Current, among the employed IP UE of user, some supports DTAP, and some does not support DTAP.That is to say that the tenability of employed some the IP UE of active user can be supported existing mobile communication network short message service and application thereof, the tenability of some IP UE cannot be supported existing mobile communication network short message service and application thereof.
For the IP UE that supports DTAP, it can discern and resolve the content of short message and the short message information of DTAP encapsulation, so IP-Message-GW is when IP UE sends the message of using IP-based message transmission protocol, the content of short message and the short message information of DTAP encapsulation can be carried in the message of using IP-based message transmission protocol, send to IP UE and handle; For the IP UE that does not support DTAP, it can not discern and resolve the content of short message and the short message information of DTAP encapsulation, so IP-Message-GW is when IP UE sends the message of using IP-based message transmission protocol, content of short message is carried in the message of using IP-based message transmission protocol, sends to IP UE and handle.
For IP-Message-GW, for the application of short message service being provided for the IP UE that supports DTAP, and the IP UE that does not support DTAP is not realized that the transmitting-receiving short message produces restriction, when the message that receives from mobile communications network based on the circuit switching signaling, tenability according to the purpose IP UE of this message judges whether purpose IP UE can support the encapsulation messages communication protocol that short message adopted that this message is carried, be DTAP, if then short message is directly adopted DTAP to be encapsulated in the message of using IP-based message transmission protocol and sends to purpose IP UE; Otherwise then the message content with short message extracts, and is carried in the message of using IP-based message transmission protocol and sends to purpose IP UE.
Similarly, the UE for using the existing mobile communication network multimedia messaging service, MMS to use should support WAP, and the network entity that WAP is used for UE and mobile communications network carries out information interaction.
For IP-Message-GW, for the application of multimedia messaging service, MMS being provided for the IP UE that supports WAP, and the IP UE that does not support WAP is not realized that the transmitting-receiving Multimedia Message produces restriction, when the message that receives from mobile communications network based on WAP, tenability according to the purpose IP UE of this message judges whether purpose IP UE can support the encapsulation messages communication protocol that Multimedia Message adopted that this message is carried, be WAP, if then Multimedia Message directly is encapsulated in the message of using IP-based message transmission protocol and sends to purpose IP UE; Otherwise then the message content with Multimedia Message extracts, and is carried in the message of using IP-based message transmission protocol and sends to purpose IP UE.
No matter in the message of using IP-based message transmission protocol, adopt the short message of DTAP structure still to adopt the Multimedia Message of WAP structure as message body, when this message is sent to purpose IP UE, all should increase the type specification of message body in this message header, the type is described the messaging protocol that is adopted according to the encapsulation messages body and is determined.For example, use the short message that adopts the DTAP structure in the message of IP-based message transmission protocol during as message body, the message body type specification in this message header can be short message service and application or DTAP; Use the Multimedia Message that adopts the WAP structure in the message of IP-based message transmission protocol during as message body, the message body type specification in this message header can be multimedia messaging service, MMS and application or WAP.
Fig. 4 is the method flow diagram of IP UE reception short message of the present invention or Multimedia Message, and its concrete steps are:
Step 401, IP-Message-GW receive based on the circuit switching signaling or based on the message of WAP, this message carries and sends to the short message of using the message communicating protocol encapsulation of purpose IP UE or the MSISDN of Multimedia Message and purpose IP UE, this message communicating agreement can be used employed DTAP for the mobile communications network short message service, perhaps is the employed WAP of mobile communication network multimedia messages application.
The MSISDN of the purpose IP UE that step 402, IP-Message-GW are carried according to this message determines the tenability of purpose IP UE.
In actual applications,, may use MSISDN, the tenability that also may use the phone unified resource identifier (TEL URI) that constitutes by MSISDN to remove to inquire about assigned ip UE according to the difference of inquiry mechanism.
Step 403, IP-Message-GW judge whether to support the short message service application of mobile communications network or multimedia messaging service, MMS to use according to the tenability of purpose IP UE, if, execution in step 406; Otherwise, execution in step 404.
Step 404, IP-Message-GW from this message carry with extracting message content the short message of message communicating protocol encapsulation or the Multimedia Message, message content is carried in the message of using IP-based message transmission protocol, send to purpose IP UE.
The MSISDN inquiry local data base of the purpose IP UE that IP-Message-GW can carry according to this message gets access to corresponding IP address.
Certainly, the present invention is according to the difference of employed IP-based message communicating agreement, addressing system to purpose IPUE also can be different, can not adopt the IP address of purpose IP UE to carry out addressing, and be to use the Session Initiation Protocol routing mechanism in the IP Multimedia System (IMS) to carry out addressing.
After step 405, purpose IP UE receive this message, read message content.
Step 406, IP-Message-GW will be carried in the message of using IP-based message transmission protocol with the short message of message communicating protocol encapsulation or the type specification of Multimedia Message and this message, send to purpose IP UE.
When with the message communicating protocol encapsulation be Multimedia Message the time, the message communicating agreement is WAP.
When with the message communicating protocol encapsulation be short message the time, the message communicating agreement is DTAP.
Similarly, the MSISDN inquiry local data base of the purpose IP UE that IP-Message-GW can carry according to this message gets access to corresponding IP address.
The present invention is according to the difference of the encapsulation message communicating agreement of using, also can difference to the addressing system of purpose IP UE, and can not adopt the IP address of purpose IP UE to carry out addressing, and be to use the SIP routing mechanism among the IMS to carry out addressing.
After step 407, purpose IP UE receive this message, use IP-based message transmission protocol to parse the message body of this message encapsulation earlier, promptly use the short message or the Multimedia Message of message communicating protocol encapsulation, the type specification that carries according to this message is resolved short message or Multimedia Message with the message communicating protocol encapsulation again, obtain the information in message content and the message header, trigger the application of corresponding messaging service according to the information in message content and the message header.
In order to realize the described processing of Fig. 4, in step 402, IP-Message-GW must be able to access the tenability of purpose IP UE, in order to address this problem, multiple scheme can be arranged.
First kind of scheme, when IP UE to the registration of the registrar of IP access network the time, just in registration message, carry the tenability of self, promptly carry and whether support mobile communications network short message service and application or multimedia messaging service, MMS and application thereof.This can be realized by expanding registration message of the prior art.When IP-Message-GW will obtain the tenability of IP UE, can obtain from registrar by the mode of third-party registration or signatory/notice (SUBSCRIBF/NOTIFY).When the bearer network of IP access network was IMS, this registrar was serving-call session control function (S-CSCF).
Second kind of scheme, before IP UE is initiating short message service mutual, the application server of preserving IP UE tenability in IP UE and the IP access network carries out alternately, the tenability of self is stored in this application server, and IP-Message-GW obtains the tenability of IP UE by inquiring about this application server.
The third scheme, this scheme depend on the strategy and the configuration of operator.Operator carries out correspondence with the type of number and the tenability of being distributed when giving IP UE assignment numbers, support mobile communications network short message service application as the tenability of number correspondence E.164 for this UE.Like this, IP-Message-GW just can determine the tenability of the number correspondence that IP UE has according to mapping relations, thereby gets access to the tenability that IPUE has.All numbers that IP UE is had all are stored among the HSS/HLR, when IP-Message-GW will obtain all numbers that IP UE had, can obtain by inquiry HSS/HLR.But, this scheme restriction is a lot, can not guarantee 100% accurately, this is because of the wireless lan (wlan) UE that much has MSISDN (MSISDN adopts number E.164 to construct), only carry out speech business probably, might not support mobile communication system short message service and application thereof or multimedia messaging service, MMS and application thereof with MSISDN.At this time also can consider by number is E.164 distributed according to number section, thereby judge and use this number terminal whether to support above-mentioned ability by discerning number section under certain number.
Fig. 5 is the signaling process figure of IP UE reception short message of the present invention, and its concrete steps are:
Step 500, purpose IP UE use general registration process to be registered on the IP-Message-GW.
Step 501, SM-SC will be carried at from the short message that UE receives the message based on the circuit switching signaling, send to SMS-GMSC, comprise content of short message and short message information in this short message, also carry the MSISDN of purpose IP UE in this message.
Step 502～503, SMS-GMSC according to the MSISDN of the entrained purpose IP UE of this message to HSS/HLR this routing iinformation of inquiry that sends a request message based on the message of circuit switching signaling, this request message comprises that this SMS-GMSC of indication supports the indication of the messaging service of the IP-based message transmission protocol of use, and HSS/HLR returns the E.164 address of three E.164 address: MSC, the E.164 address of SGSN and the E.164 address of IP-Message-GW to SMS-GMSC.
Step 504, SMS-GMSC transmit this message based on the circuit switching signaling according to the address that obtains, and supposition here selects the E.164 address of IP-Message-GW to transmit this message.
The MSISDN of the purpose IP UE that step 505, IP-Message-GW are carried according to this message determines the tenability of purpose IP UE.
Step 506, IP-Message-GW judge according to the tenability of this purpose IP UE whether this purpose IPUE supports the short message service and the application thereof of mobile communications network, if, execution in step 508; Otherwise, execution in step 507.
Step 507, IP-Message-GW extract content of short message from the short message with the DTAP encapsulation that this message is carried, content of short message is carried in the message of using IP-based message transmission protocol, send to purpose IP UE according to the IP address of purpose IP UE or according to the sign of purpose IP UE by the SIP route, after purpose IP UE receives this message, read content of short message, change step 509 over to.
Step 508, IP-Message-GW extracts the entrained short message with the DTAP encapsulation from this message, to be carried in the message of using IP-based message transmission protocol with the short message of DTAP encapsulation and the type specification of this message, send to purpose IP UE according to the IP address of purpose IP UE or according to the sign of purpose IP UE, after purpose IP UE receives this message of using IP-based message transmission protocol, use IP-based message transmission protocol to parse the message body of this message encapsulation earlier, promptly with the short message of DTAP encapsulation, the type specification that carries according to this message is resolved the short message that encapsulates with DTAP again, obtain the information in message content and the message header, carry out the application of corresponding messaging service according to the information in message content and the message header, change step 509 over to.
After step 509, IP-Message-GW send the message of using IP-based message transmission protocol, transmit report for the SMS-GMSC return messages.
Step 510, SMS-GMSC transmit report condition for the HSS/HLR return messages.
Step 511, SMS-GMSC transmit report for the SM-SC return messages.
Below specify when IP UE sends SMS message, how to realize the application of mobile communications network short message.
The present invention both can send the message of the IP-based message transmission protocol of use that carries content of short message for the IP UE that supports short message service and application thereof, can send the message of carrying by the IP-based message transmission protocol of use of DTAP encapsulation again.Considering short message service some demands in using, such as downloading business such as the tinkle of bells picture, is to need the user import specific character combination on terminal, and the while, the destination Mobile Station International ISDN Number place filled out that a number of service provider's appointment realizes.This destination Mobile Station International ISDN Number here also is that existing mobile communications network distributes, GMSC/SMS-IWMSC in the circuit-switched network and SM-SC send to corresponding service provider according to this destination Mobile Station International ISDN Number with short message, the service provider triggers the applied logic that user's request is returned in corresponding configuration according to the input combination of IP UE, user terminal is after receiving this applied logic, with its parsing and execution, wish the application of downloading according to the rule that sets in advance thereby obtain this user.Therefore, IP UE wishes also can use identical business in IP network, giving the service provider of appointment by IP-Message-GW and GMSC/SMS-IWMSC, it is specific destination Mobile Station International ISDN Number, sending specific character makes up when asking an application, need the short message of structure with the DTAP encapsulation, send IP-Message-GW in the message that will be carried at the IP-based message transmission protocol of use with the short message and the type specification of DTAP encapsulation, the type specification that IP-Message-GW carries according to this message determines that the short message with the DTAP encapsulation that directly this message is carried is filled to the complete message based on the circuit switching signaling and sends to GMSC/SMS-IWMSC, by GMSC/SMS-IWMSC it is handled as an existing message based on the circuit switching signaling, give SM-SC, and then SM-SC sends it to the service provider according to destination Mobile Station International ISDN Number and further handles.
In this is realized, IP UE at first constructs a short message with the DTAP encapsulation according to the application realization mechanism of mobile communications network short message service, partial information in the short message, as the position relation information between IP UE and the mobile communications network, if obtain less than, can not fill the part that can fill, as destination Mobile Station International ISDN Number etc., fill according to the usage in the existing mobile communications network exactly.Secondly, send IP-Message-GW in the message that IP UE will be carried at the IP-based message transmission protocol of use with the short message and the type specification of DTAP encapsulation.At last, the type specification that IP-Message-GW carries according to this message obtains out the short message with the DTAP encapsulation that this message is carried, after filling the partial information that does not have in the short message to fill, use sends to GMSC/SMS-IWMSC based on the message of circuit switching signaling, and then send to SM-SC, send to the service provider by SM-SC and handle.
The short message that adopts the DTAP structure in the message of using IP-based message transmission protocol is as message body, when this message is sent to IP-Message-GW by IP UE, should increase the type specification of message body in this message header, the type is described according to the tenability of IP UE and is determined.For example, when IP UE supported DTAP, the message body type specification in this message header can be short message service and application or DTAP.
The signaling process figure that Fig. 6 sends SMS message for IP UE of the present invention, its concrete steps are:
Step 600, IP UE use general registration process to be registered on the IP-Message-GW.
Step 601, IP UE send the message of the IP-based message transmission protocol of use to IP-Message-GW, carry short message and type specification through the DTAP encapsulation in this message, and this short message comprises content of short message and short message information.
The type specification that step 602, IP-Message-GW carry according to this message is determined to go out the short message that encapsulates through DTAP from this message extraction, and get access to corresponding MSISDN at the log-on message of HSS/HLR by the IP address of IP UE or the sign of purpose IP UE according to IP UE, the short message of structure process DTAP encapsulation uses the message based on the circuit switching signaling to send to SMS-IWMSC according to the MSISDN of IP UE.
Step 603, SMS-IWMSC forward the message to SM-SC.
The message that sends step 604, SM-SC transmits and reports to SMS-IWMSC.
